+Before the move to GitHub, this was the only record of changes to PCRE2. Now +there is also the log of commit messages. + +Version 10.44 07-June-2024 +-------------------------- + +1. If a pattern contained a variable-length lookbehind in which the first +branch was not the one with the shortest minimum length, and the lookbehind +contained a capturing group, and elsewhere in the pattern there was another +lookbehind that referenced that group, the pattern was incorrectly compiled, +leading to unpredictable results, including crashes in JIT compiling. An +example pattern is: /(((?<=123?456456|ABC)))(?<=\2)/ + +2. Further updates to the oss-fuzz support: + + (a) Limit quantifiers for groups and classes to be no more than 10. This + avoids very long JIT compile times that happen in some cases when groups + are replicated for quantification, and very long match times when + classes contain a lot of non-ascii characters. + + (b) Added PCRE2_EXTENDED_MORE to the list of allowed options. + + (c) Arranged for text error messages to be shown in 16-bit and 32-bit modes. + + (d) Made the output in standalone mode more readable. + + (e) General code tidies. + + (f) Limit the size of compiled patterns to 10MB (see 6 below). + + (g) Do not run JIT on patterns whose compiled length is greater than 200K + bytes because this takes a long time, causing oss-fuzz to time out. + + (h) Avoid compiling or matching twice with the same options (this could + happen if the input didn't set any options). + +3. Increase the maximum length of a name for a group from 32 to 128 because +there is a user for whom 32 is too small. + +4. Cause pcre2test to output a message when pcre2_jit_compile() gives an error +return if either jitverify or info is specified. + +5. Some auxiliary files for building under OpenVMS that were contributed by +Alexey Chupahin have been installed. + +6. Added pcre2_set_max_pattern_compiled_length() to limit the size of compiled +patterns. + +7. There was a bug in the implementation of \X caused by my (PH) misreading or +misunderstanding one of the grapheme sequence breaking rules in Unicode Annex +#29. A break should occur between two characters with the Extended Pictographic +break property unless a zero-width joiner intervenes. PCRE2 was not insisting +on the ZWJ, causing \X to match more than it should. See GitHub issue #410. + +8. Avoid compilation issues with proprietary compilers in UNIX since 10.43. + + +Version 10.43 16-February-2024 +------------------------------ + +1. The test program added by change 2 of 10.42 didn't work when the default +newline setting didn't include \n as a newline. One test needed (*LF) to ensure +that it worked. + +2. Added the new freestanding POSIX test program to the ManyConfigTests script +in the maint directory (overlooked in 2 below). Also improved the selection +facilities in that script, and added a test with JIT in a non-source directory, +fixing an oversight that would have made such a test fail before. + +3. Added pcre2_get_match_data_heapframes_size() and related pcre2test flags +to allow for finer control of the heap used when pcre2_match() without JIT is +used and the match_data might be reused. This began as PR #191, but has had +further refinement and documentation edits. + +4. Applied PR #181, which tidies some casts in pcre2_valid_utf.c. + +5. Applied PR #184, which avoids overflow issues with the heap limit +(introduced in 10.41/9). + +6. Applied PR #192, which changes the timing units for pcre2test from +milliseconds to microseconds. This is more useful for modern CPUs. + +7. Applied PR #193, which makes the requirement for C99 explicit in +configure.ac and CMakeLists.txt. + +8. Fixed a bug in pcre2test when a ridiculously large string repeat required a +stupid amount of memory. It now gives a clean realloc() failure error. + +9. Updates to restrict the interaction between ASCII and non-ASCII characters +for caseless matching and items like \d: + + (a) Added PCRE2_EXTRA_CASELESS_RESTRICT to lock out mixing of ASCII and + non-ASCII when matching caselessly. This is also /r in pcre2test and + (?r) within patterns. + + (b) Added PCRE2_EXTRA_ASCII_{BSD,BSS,BSW,POSIX} and corresponding (?aD) etc + in patterns and /a in pcre2test. + + (c) Corresponding updates to pcre2test. + +10. Unicode has been updated to 15.0.0. + +11. The Python scripts and ucptest.c in maint have been updated (a) a minor +change needed for 9(a) above; (b) fix bugs in ucptest, + +12. Integer overflow testing is now centralized in a new function. + +13. Made PCRE2_UCP the default in UTF mode in pcre2grep, and added new options +--case-restrict and --no-ucp. + +14. In the debugging printint module (which is normally only linked into +pcre2test), avoid the use of a variable called "not" because that's deprecated +in C and forbidden in C++. Also rewrite some code to avoid a goto into a block +that bypassed its initialization (though it didn't actually matter). + +15. More minor code adjustments to avoid using reserved C++ words as variable +names ("new" and "typename") and another jump that bypassed an (irrelevant) +initialization. + +16. Merged a pull request that removed pcre2_ucptables.c from the list of files +to compile in NON-AUTOTOOLS-BUILD because it is #included in pcre2_tables.c. +Also adjusted the BUILD.bazel and build.zig files, which had the same issue. At +the same time, fixed a typo in the Bazel file. + +17. Add PCRE2_EXTRA_ASCII_DIGIT to allow [:digit:] to be kept on sync with \d +even in UCP mode. + +18. Fix an invalid match of ascii word classes when invalid utf is enabled. + +19. Add a --posix-digit to pcre2grep for compatibility with GNU grep, and +other tools that prefer the POSIX compatible unicode definition for \d. + +20. Report the bit width of the library in use by pcre2test for usability. + +21. A pathological pattern conversion test could result in a string longer than +the available input buffer. Cause such a test to fail. + +22. Add a check that forces a compiler error if PCRE2_CODE_UNIT_WIDTH is not 8, +16, or 32 when compiling any of the library modules. + +23. Update pcre2_compile() to treat a NULL pattern with zero length as an empty +string. + +24. Add support for limited-length variable-length lookbehind assertions, with +default maximum length 255 characters (same as Perl) but with a function to +adjust the limit. + +25. Applied pull request #262, which updates the zig configuration, and #278 +which fixes a bug with out-of-source-tree CMake build testing. + +26. Add support for LoongArch to JIT. + +27. Fixed a bug in pcre2_match() in the code for handling the vector of +backtracking frames on the heap, which caused a heap overflow if *LIMIT_HEAP +restricted an attempt to extend to less than the frame size. Generally tidy up +the code for extending the heap frames vector. This fixes GitHub issue #275. + +28. Update pcre2_fuzzsupport.c to avoid clang sanitize complaint about shifting +left by 16 when there are non-zeros in the top 16 bits. + +29. Perl 5.34.0 changed the meaning of (for example) {,3} which did not used to +be treated as a quantifier. Now it is interpreted as {0,3} and PCRE2 has +changed to match. Note that {,} is still not a quantifier. + +30. Perl allows spaces and/or horizontal tabs after { or before } in all items +that use braces, and also before or after the comma in quantifiers. PCRE2 now +does the same, except for \u{...}, which is recognized only when +PCRE2_EXTRA_ALT_BSUX is set. This an ECMAScript, non-Perl compatible, +extension, so PCRE2 follows ECMAScript rather than Perl. + +31. Applied pull request #300 by Carlo, which fixes #261. The bug was that +pcre2_match() was not fully resetting all captures that had been set within a +(possibly recursive) subroutine call such as (?3). + +32. Changed the meaning of \w (and its synonyms) in UCP mode to match Perl. It +now matches characters whose general categories are L or N or whose particular +categories are Mn (non-spacing mark) or Pc (combining punctuation). The latter +includes underscore. + +33. Changed the meaning of [:xdigit:] in UCP mode to match Perl. It now also +matches the "fullwidth" versions of the hex digits. Just like it is done for +[:digit:], PCRE2_EXTRA_ASCII_DIGIT can be used to keep this class ASCII only +without affecting other POSIX classes. + +34. GitHub PR305 fixes a potential integer overflow in pcre2_dfa_match(). + +35. Updated handling of \b and \B in UCP mode to match the changes to \w in 32 +above because \b and \B are defined in terms of \w. + +36. Within a pattern (?aT) and (?-aT) set and reset the PCRE2_EXTRA_ASCII_DIGIT +option, and (?aP) also sets (?aT) so that (?-aP) disables all ASCII +restrictions on POSIX classes. + +37. If PCRE2_FIRSTLINE was set on an anchored pattern, pcre2_match() and +pcre2_dfa_match() misbehaved. PCRE2_FIRSTLINE is now ignored for anchored +patterns. + +38. Add a test for ridiculous ovector offset values to the substring extraction +functions. + +39. Make OP_REVERSE use IMM2_SIZE for its data instead of LINK_SIZE, for +consistency with OP_VREVERSE. + +40. In some legacy environments with a pre C99 snprintf, pcre2_regerror could +return an incorrect value when the provided buffer was too small. + +41. Applied pull request #342 which adds sanity checks for ctype functions and +locks out any accidental sign-extension. + +42. In the 32-bit library, in non-UTF mode, a quantifier that followed a +literal character with a value greater than or equal to 0x80000000u caused +undefined behaviour. + +43. \z was misbehaving when matching fragments inside invalid UTF strings. + +44. Implement --group-separator and --no-group-separator for pcre2grep. + +45. Fix \X matching in 32 bit mode without UTF in JIT. + +46. Fix backref iterators when PCRE2_MATCH_UNSET_BACKREF is set in JIT. + +47. Refactor the handling of whole-pattern recursion (?0) in pcre2_match() so +that its end is handled similarly to other recursions. This has altered the +behaviour of /|(?0)./endanchored which was previously not right. + +48. Improved the test for looping recursion by checking the last referenced +character as well as the current character. This allows some patterns that +previously triggered the check to run to completion instead of giving the loop +error. + +49. In 32-bit mode, the compiler looped for the pattern /[\x{ffffffff}]/ when +PCRE2_CASELESS and PCRE2_UCP (but not PCRE2_UTF) were set. Fixed by not trying +to look for other cases for characters above the Unicode range. + +50. In caseless 32-bit mode with UCP (but not UTF) set, the character +0xffffffff incorrectly matched any character that has more than one other case, +in particular k and s. + +51. Fix accept and endanchored interaction in JIT. + +52. Fix backreferences with unset backref and non-greedy iterators in JIT. + +53. Improve the logic that checks for a list of starting code units -- positive +lookahead assertions are now ignored if the immediately following item is one +that sets a mandatory starting character. For example, /a?(?=bc|)d/ used to set +all of a, b, and d as possible starting code units; now it sets only a and d. + +54. Fix incorrect class character matches in JIT. + +55. In pcre2test, ensure pcre2_jit_match() is used when jitfast is used with +substitution testing. + +56. Insert omitted setting of subject length in match data at the end of +pcre2_jit_match(). + +57. Implemented PCRE2_DISABLE_RECURSELOOP_CHECK for pcre2_match() to enable +some apparently looping recursions to run to completion and therefore match the +JIT behaviour. With this set, real loops will eventually get caught by match or +heap limits or run out of resource. + +58. AC did a lot of work on pcre2_fuzzsupport.c to extend it to 16-bit and +32-bit libraries and to compare JIT and non-JIT matching. + + +Version 10.42 11-December-2022 +------------------------------ + +1. Change 19 of 10.41 wasn't quite right; it put the definition of a default, +empty value for PCRE2_CALL_CONVENTION in src/pcre2posix.c instead of +src/pcre2posix.h, which meant that programs that included pcre2posix.h but not +pcre2.h failed to compile. + +2. To catch similar issues to the above in future, a new small test program +that includes pcre2posix.h but not pcre2.h has been added to the test suite. + +3. When the -S option of pcre2test was used to set a stack size greater than +the allowed maximum, the error message displayed the hard limit incorrectly. +This was pointed out on GitHub pull request #171, but the suggested patch +didn't cope with all cases. Some further modification was required. + +4. Supplying an ovector count of more than 65535 to pcre2_match_data_create() +caused a crash because the field in the match data block is only 16 bits. A +maximum of 65535 is now silently applied. + +5. Merged @carenas patch #175 which fixes #86 - segfault on aarch64 (ARM), + +6. The prototype for pcre2_substring_list_free() specified its argument as +PCRE2_SPTR * which is a const data type, whereas the yield from +pcre2_substring_list() is not const. This caused compiler warnings. I have +changed the argument of pcre2_substring_list_free() to be PCRE2_UCHAR ** to +remove this anomaly. This might cause new warnings in existing code where a +cast has been used to avoid previous ones. + + +Version 10.41 06-December-2022 +------------------------------ + +1. Add fflush() before and after a fork callout in pcre2grep to get its output +to be the same on all systems. (There were previously ordering differences in +Alpine Linux). + +2. Merged patch from @carenas (GitHub #110) for pthreads support in CMake. + +3. SSF scorecards grumbled about possible overflow in an expression in +pcre2test. It never would have overflowed in practice, but some casts have been +added and at the some time there's been some tidying of fprints that output +size_t values. + +4. PR #94 showed up an unused enum in pcre2_convert.c, which is now removed. + +5. Minor code re-arrangement to remove gcc warning about realloc() in +pcre2test. + +6. Change a number of int variables that hold buffer and line lengths in +pcre2grep to PCRE2_SIZE (aka size_t). + +7. Added an #ifdef to cut out a call to PRIV(jit_free) when JIT is not +supported (even though that function would do nothing in that case) at the +request of a user who doesn't even want to link with pcre_jit_compile.o. Also +tidied up an untidy #ifdef arrangement in pcre2test. + +8. Fixed an issue in the backtracking optimization of character repeats in +JIT. Furthermore optimize star repetitions, not just plus repetitions. + +9. Removed the use of an initial backtracking frames vector on the system stack +in pcre2_match() so that it now always uses the heap. (In a multi-thread +environment with very small stacks there had been an issue.) This also is +tidier for JIT matching, which didn't need that vector. The heap vector is now +remembered in the match data block and re-used if that block itself is re-used. +It is freed with the match data block. + +10. Adjusted the find_limits code in pcre2test to work with change 9 above. + +11. Added find_limits_noheap to pcre2test, because the heap limits are now +different in different environments and so cannot be included in the standard +tests. + +12. Created a test for pcre2_match() heap processing that is not part of the +tests run by 'make check', but can be run manually. The current output is from +a 64-bit system. + +13. Implemented -Z aka --null in pcre2grep. + +14. A minor change to pcre2test and the addition of several new pcre2grep tests +have improved LCOV coverage statistics. At the same time, code in pcre2grep and +elsewhere that can never be obeyed in normal testing has been excluded from +coverage. + +15. Fixed a bug in pcre2grep that could cause an extra newline to be written +after output generated by --output. + +16. If a file has a .bz2 extension but is not in fact compressed, pcre2grep +should process it as a plain text file. A bug stopped this happening; now fixed +and added to the tests. + +17. When pcre2grep was running not in UTF mode, if a string specified by +--output or obtained from a callout in a pattern contained a character (byte) +greater than 127, it was incorrectly output in UTF-8 format. + +18. Added some casts after warnings from Clang sanitize. + +19. Merged patch from cbouc (GitHub #139): 4 function prototypes were missing +PCRE2_CALL_CONVENTION in src/pcre2posix.h. All function prototypes returning +pointers had out of place PCRE2_CALL_CONVENTION in src/pcre2.h.*. These +produced errors when building for Windows with #define PCRE2_CALL_CONVENTION +__stdcall. + +20. A negative repeat value in a pcre2test subject line was not being +diagnosed, leading to infinite looping. + +21. Updated RunGrepTest to discard the warning that Bash now gives when setting +LC_CTYPE to a bad value (because older versions didn't). + +22. Updated pcre2grep so that it behaves like GNU grep when matching more than +one pattern and a later pattern matches at an earlier point in the subject when +the matched substrings are being identified by colour or by offsets. + +23. Updated the PrepareRelease script so that the man page that it makes for +the pcre2demo demonstration program is more standard and does not cause errors +when processed by lexgrog or mandb -c (GitHub issue #160). + +24. The JIT compiler was updated. + + +Version 10.40 15-April-2022 +--------------------------- + +1. Merged patch from @carenas (GitHub #35, 7db87842) to fix pcre2grep incorrect +handling of multiple passes. + +2. Merged patch from @carenas (GitHub #36, dae47509) to fix portability issue +in pcre2grep with buffered fseek(stdin). + +3. Merged patch from @carenas (GitHub #37, acc520924) to fix tests when -S is +not supported. + +4. Revert an unintended change in JIT repeat detection. + +5. Merged patch from @carenas (GitHub #52, b037bfa1) to fix build on GNU Hurd. + +6. Merged documentation and comments patches from @carenas (GitHub #47). + +7. Merged patch from @carenas (GitHub #49) to remove obsolete JFriedl test code +from pcre2grep. + +8. Merged patch from @carenas (GitHub #48) to fix CMake install issue #46. + +9. Merged patch from @carenas (GitHub #53) fixing NULL checks in matching and +substituting. + +10. Add null_subject and null_replacement modifiers to pcre2test. + +11. Add check for NULL subject to POSIX regexec() function. + +12. Add check for NULL replacement to pcre2_substitute(). + +13. For the subject arguments of pcre2_match(), pcre2_dfa_match(), and +pcre2_substitute(), and the replacement argument of the latter, if the pointer +is NULL and the length is zero, treat as an empty string. Apparently a number +of applications treat NULL/0 in this way. + +14. Added support for Bidi_Class and a number of binary Unicode properties, +including Bidi_Control. + +15. Fix some minor issues raised by clang sanitize. + +16. Very minor code speed up for maximizing character property matches. + +17. A number of changes to script matching for \p and \P: + + (a) Script extensions for a character are now coded as a bitmap instead of + a list of script numbers, which should be faster and does not need a + loop. + + (b) Added the syntax \p{script:xxx} and \p{script_extensions:xxx} (synonyms + sc and scx). + + (c) Changed \p{scriptname} from being the same as \p{sc:scriptname} to being + the same as \p{scx:scriptname} because this change happened in Perl at + release 5.26. + + (d) The standard Unicode 4-letter abbreviations for script names are now + recognized. + + (e) In accordance with Unicode and Perl's "loose matching" rules, spaces, + hyphens, and underscores are ignored in property names, which are then + matched independent of case. + +18. The Python scripts in the maint directory have been refactored. There are +now three scripts that generate pcre2_ucd.c, pcre2_ucp.h, and pcre2_ucptables.c +(which is #included by pcre2_tables.c). The data lists that used to be +duplicated are now held in a single common Python module. + +19. On CHERI, and thus Arm's Morello prototype, pointers are represented as +hardware capabilities, which consist of both an integer address and additional +metadata, meaning they are twice the size of the platform's size_t type, i.e. +16 bytes on a 64-bit system. The ovector member of heapframe happens to only be +8 byte aligned, and so computing frame_size ended up with a multiple of 8 but +not 16. Whilst the first frame was always suitably aligned, this then +misaligned the frame that follows, resulting in an alignment fault when storing +a pointer to Fecode at the start of match. Patch to fix this issue by Jessica +Clarke PR#72. + +20. Added -LP and -LS listing options to pcre2test. + +21. A user discovered that the library names in CMakeLists.txt for MSVC +debugger (PDB) files were incorrect - perhaps never tried for PCRE2? + +22. An item such as [Aa] is optimized into a caseless single character match. +When this was quantified (e.g. [Aa]{2}) and was also the last literal item in a +pattern, the optimizing "must be present for a match" character check was not +being flagged as caseless, causing some matches that should have succeeded to +fail. + +23. Fixed a unicode property matching issue in JIT. The character was not +fully read in caseless matching. + +24. Fixed an issue affecting recursions in JIT caused by duplicated data +transfers. + +25. Merged patch from @carenas (GitHub #96) which fixes some problems with +pcre2test and readline/readedit: + + * Use the right header for libedit in FreeBSD with autoconf + * Really allow libedit with cmake + * Avoid using readline headers with libedit + + +Version 10.39 29-October-2021 +----------------------------- + +1. Fix incorrect detection of alternatives in first character search in JIT. + +2. Merged patch from @carenas (GitHub #28): + + Visual Studio 2013 includes support for %zu and %td, so let newer + versions of it avoid the fallback, and while at it, make sure that + the first check is for DISABLE_PERCENT_ZT so it will be always + honoured if chosen. + + prtdiff_t is signed, so use a signed type instead, and make sure + that an appropriate width is chosen if pointers are 64bit wide and + long is not (ex: Windows 64bit). + + IMHO removing the cast (and therefore the possibility of truncation) + make the code cleaner and the fallback is likely portable enough + with all 64-bit POSIX systems doing LP64 except for Windows. + +3. Merged patch from @carenas (GitHub #29) to update to Unicode 14.0.0. + +4. Merged patch from @carenas (GitHub #30): + + * Cleanup: remove references to no longer used stdint.h + + Since 19c50b9d (Unconditionally use inttypes.h instead of trying for stdint.h + (simplification) and remove the now unnecessary inclusion in + pcre2_internal.h., 2018-11-14), stdint.h is no longer used. + + Remove checks for it in autotools and CMake and document better the expected + build failures for systems that might have stdint.h (C99) and not inttypes.h + (from POSIX), like old Windows. + + * Cleanup: remove detection for inttypes.h which is a hard dependency + + CMake checks for standard headers are not meant to be used for hard + dependencies, so will prevent a possible fallback to work. + + Alternatively, the header could be checked to make the configuration fail + instead of breaking the build, but that was punted, as it was missing anyway + from autotools. + +5. Merged patch from @carenas (GitHub #32): + + * jit: allow building with ancient MSVC versions + + Visual Studio older than 2013 fails to build with JIT enabled, because it is + unable to parse non C89 compatible syntax, with mixed declarations and code. + While most recent compilers wouldn't even report this as a warning since it + is valid C99, it could be also made visible by adding to gcc/clang the + -Wdeclaration-after-statement flag at build time. + + Move the code below the affected definitions. + + * pcre2grep: avoid mixing declarations with code + + Since d5a61ee8 (Patch to detect (and ignore) symlink loops in pcre2grep, + 2021-08-28), code will fail to build in a strict C89 compiler. + + Reformat slightly to make it C89 compatible again. + + +Version 10.38 01-October-2021 +----------------------------- + +1. Fix invalid single character repetition issues in JIT when the repetition +is inside a capturing bracket and the bracket is preceded by character +literals. + +2. Installed revised CMake configuration files provided by Jan-Willem Blokland. +This extends the CMake build system to build both static and shared libraries +in one go, builds the static library with PIC, and exposes PCRE2 libraries +using the CMake config files. JWB provided these notes: + +- Introduced CMake variable BUILD_STATIC_LIBS to build the static library. + +- Make a small modification to config-cmake.h.in by removing the PCRE2_STATIC + variable. Added PCRE2_STATIC variable to the static build using the + target_compile_definitions() function. + +- Extended the CMake config files. + + - Introduced CMake variable PCRE2_USE_STATIC_LIBS to easily switch between + the static and shared libraries. + + - Added the PCRE_STATIC variable to the target compile definitions for the + import of the static library. + +Building static and shared libraries using MSVC results in a name clash of +the libraries. Both static and shared library builds create, for example, the +file pcre2-8.lib. Therefore, I decided to change the static library names by +adding "-static". For example, pcre2-8.lib has become pcre2-8-static.lib. +[Comment by PH: this is MSVC-specific. It doesn't happen on Linux.] + +3. Increased the minimum release number for CMake to 3.0.0 because older than +2.8.12 is deprecated (it was set to 2.8.5) and causes warnings. Even 3.0.0 is +quite old; it was released in 2014. + +4. Implemented a modified version of Thomas Tempelmann's pcre2grep patch for +detecting symlink loops. This is dependent on the availability of realpath(), +which is now tested for in ./configure and CMakeLists.txt. + +5. Implemented a modified version of Thomas Tempelmann's patch for faster +case-independent "first code unit" searches for unanchored patterns in 8-bit +mode in the interpreters. Instead of just remembering whether one case matched +or not, it remembers the position of a previous match so as to avoid +unnecessary repeated searching. + +6. Perl now locks out \K in lookarounds, so PCRE2 now does the same by default. +However, just in case anybody was relying on the old behaviour, there is an +option called PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK that enables the old behaviour. +An option has also been added to pcre2grep to enable this. + +7. Re-enable a JIT optimization which was unintentionally disabled in 10.35. + +8. There is a loop counter to catch excessively crazy patterns when checking +the lengths of lookbehinds at compile time. This was incorrectly getting reset +whenever a lookahead was processed, leading to some fuzzer-generated patterns +taking a very long time to compile when (?|) was present in the pattern, +because (?|) disables caching of group lengths. + + +Version 10.37 26-May-2021 +------------------------- + +1. Change RunGrepTest to use tr instead of sed when testing with binary +zero bytes, because sed varies a lot from system to system and has problems +with binary zeros. This is from Bugzilla #2681. Patch from Jeremie +Courreges-Anglas via Nam Nguyen. This fixes RunGrepTest for OpenBSD. Later: +it broke it for at least one version of Solaris, where tr can't handle binary +zeros. However, that system had /usr/xpg4/bin/tr installed, which works OK, so +RunGrepTest now checks for that command and uses it if found. + +2. Compiling with gcc 10.2's -fanalyzer option showed up a hypothetical problem +with a NULL dereference. I don't think this case could ever occur in practice, +but I have put in a check in order to get rid of the compiler error. + +3. An alternative patch for CMakeLists.txt because 10.36 #4 breaks CMake on +Windows. Patch from email@cs-ware.de fixes bugzilla #2688. + +4. Two bugs related to over-large numbers have been fixed so the behaviour is +now the same as Perl. + + (a) A pattern such as /\214748364/ gave an overflow error instead of being + treated as the octal number \214 followed by literal digits. + + (b) A sequence such as {65536 that has no terminating } so is not a + quantifier was nevertheless complaining that a quantifier number was too big. + +5. A run of autoconf suggested that configure.ac was out-of-date with respect +to the latest autoconf. Running autoupdate made some valid changes, some valid +suggestions, and also some invalid changes, which were fixed by hand. Autoconf +now runs clean and the resulting "configure" seems to work, so I hope nothing +is broken. Later: the requirement for autoconf 2.70 broke some automatic test +robots. It doesn't seem to be necessary: trying a reduction to 2.60. + +6. The pattern /a\K.(?0)*/ when matched against "abac" by the interpreter gave +the answer "bac", whereas Perl and JIT both yield "c". This was because the +effect of \K was not propagating back from the full pattern recursion. Other +recursions such as /(a\K.(?1)*)/ did not have this problem. + +7. Restore single character repetition optimization in JIT. Currently fewer +character repetitions are optimized than in 10.34. + +8. When the names of the functions in the POSIX wrapper were changed to +pcre2_regcomp() etc. (see change 10.33 #4 below), functions with the original +names were left in the library so that pre-compiled programs would still work. +However, this has proved troublesome when programs link with several libraries, +some of which use PCRE2 via the POSIX interface while others use a native POSIX +library. For this reason, the POSIX function names are removed in this release. +The macros in pcre2posix.h should ensure that re-compiling fixes any programs +that haven't been compiled since before 10.33. + + +Version 10.36 04-December-2020 +------------------------------ + +1. Add CET_CFLAGS so that when Intel CET is enabled, pass -mshstk to +compiler. This fixes https://bugs.exim.org/show_bug.cgi?id=2578. Patch for +Makefile.am and configure.ac by H.J. Lu. Equivalent patch for CMakeLists.txt +invented by PH. + +2. Fix infinite loop when a single byte newline is searched in JIT when +invalid utf8 mode is enabled. + +3. Updated CMakeLists.txt with patch from Wolfgang Stöggl (Bugzilla #2584): + + - Include GNUInstallDirs and use ${CMAKE_INSTALL_LIBDIR} instead of hardcoded + lib. This allows differentiation between lib and lib64. + CMAKE_INSTALL_LIBDIR is used for installation of libraries and also for + pkgconfig file generation. + + - Add the version of PCRE2 to the configuration summary like ./configure + does. + + - Fix typo: MACTHED_STRING->MATCHED_STRING + +4. Updated CMakeLists.txt with another patch from Wolfgang Stöggl (Bugzilla +#2588): + + - Add escaped double quotes around include directory in CMakeLists.txt to + allow spaces in directory names. + + - This fixes a cmake error, if the path of the pcre2 source contains a space. + +5. Updated CMakeLists.txt with a patch from B. Scott Michel: CMake's +documentation suggests using CHECK_SYMBOL_EXISTS over CHECK_FUNCTION_EXIST. +Moreover, these functions come from specific header files, which need to be +specified (and, thankfully, are the same on both the Linux and WinXX +platforms.) + +6. Added a (uint32_t) cast to prevent a compiler warning in pcre2_compile.c. + +7. Applied a patch from Wolfgang Stöggl (Bugzilla #2600) to fix postfix for +debug Windows builds using CMake. This also updated configure so that it +generates *.pc files and pcre2-config with the same content, as in the past. + +8. If a pattern ended with (?(VERSION=n.d where n is any number but d is just a +single digit, the code unit beyond d was being read (i.e. there was a read +buffer overflow). Fixes ClusterFuzz 23779. + +9. After the rework in r1235, certain character ranges were incorrectly +handled by an optimization in JIT. Furthermore a wrong offset was used to +read a value from a buffer which could lead to memory overread. + +10. Unnoticed for many years was the fact that delimiters other than / in the +testinput1 and testinput4 files could cause incorrect behaviour when these +files were processed by perltest.sh. There were several tests that used quotes +as delimiters, and it was just luck that they didn't go wrong with perltest.sh. +All the patterns in testinput1 and testinput4 now use / as their delimiter. +This fixes Bugzilla #2641. + +11. Perl has started to give an error for \K within lookarounds (though there +are cases where it doesn't). PCRE2 still allows this, so the tests that include +this case have been moved from test 1 to test 2. + +12. Further to 10 above, pcre2test has been updated to detect and grumble if a +delimiter other than / is used after #perltest. + +13. Fixed a bug with PCRE2_MATCH_INVALID_UTF in 8-bit mode when PCRE2_CASELESS +was set and PCRE2_NO_START_OPTIMIZE was not set. The optimization for finding +the start of a match was not resetting correctly after a failed match on the +first valid fragment of the subject, possibly causing incorrect "no match" +returns on subsequent fragments. For example, the pattern /A/ failed to match +the subject \xe5A. Fixes Bugzilla #2642. + +14. Fixed a bug in character set matching when JIT is enabled and both unicode +scripts and unicode classes are present at the same time. + +15. Added GNU grep's -m (aka --max-count) option to pcre2grep. + +16. Refactored substitution processing in pcre2grep strings, both for the -O +option and when dealing with callouts. There is now a single function that +handles $ expansion in all cases (instead of multiple copies of almost +identical code). This means that the same escape sequences are available +everywhere, which was not previously the case. At the same time, the escape +sequences $x{...} and $o{...} have been introduced, to allow for characters +whose code points are greater than 255 in Unicode mode. + +17. Applied the patch from Bugzilla #2628 to RunGrepTest. This does an explicit +test for a version of sed that can handle binary zero, instead of assuming that +any Linux version will work. Later: replaced $(...) by `...` because not all +shells recognize the former. + +18. Fixed a word boundary check bug in JIT when partial matching is enabled. + +19. Fix ARM64 compilation warning in JIT. Patch by Carlo. + +20. A bug in the RunTest script meant that if the first part of test 2 failed, +the failure was not reported. + +21. Test 2 was failing when run from a directory other than the source +directory. This failure was previously missed in RunTest because of 20 above. +Fixes added to both RunTest and RunTest.bat. + +22. Patch to CMakeLists.txt from Daniel to fix problem with testing under +Windows. + + +Version 10.35 09-May-2020 +--------------------------- + +1. Use PCRE2_MATCH_EMPTY flag to detect empty matches in JIT. + +2. Fix ARMv5 JIT improper handling of labels right after a constant pool. + +3. A JIT bug is fixed which allowed to read the fields of the compiled +pattern before its existence is checked. + +4. Back in the PCRE1 day, capturing groups that contained recursive back +references to themselves were made atomic (version 8.01, change 18) because +after the end a repeated group, the captured substrings had their values from +the final repetition, not from an earlier repetition that might be the +destination of a backtrack. This feature was documented, and was carried over +into PCRE2. However, it has now been realized that the major refactoring that +was done for 10.30 has made this atomizing unnecessary, and it is confusing +when users are unaware of it, making some patterns appear not to be working as +expected. Capture values of recursive back references in repeated groups are +now correctly backtracked, so this unnecessary restriction has been removed. + +5. Added PCRE2_SUBSTITUTE_LITERAL. + +6. Avoid some VS compiler warnings. + +7. Added PCRE2_SUBSTITUTE_MATCHED. + +8. Added (?* and (?<* as synonyms for (*napla: and (*naplb: to match another +regex engine. The Perl regex folks are aware of this usage and have made a note +about it. + +9. When an assertion is repeated, PCRE2 used to limit the maximum repetition to +1, believing that repeating an assertion is pointless. However, if a positive +assertion contains capturing groups, repetition can be useful. In any case, an +assertion could always be wrapped in a repeated group. The only restriction +that is now imposed is that an unlimited maximum is changed to one more than +the minimum. + +10. Fix *THEN verbs in lookahead assertions in JIT. + +11. Added PCRE2_SUBSTITUTE_REPLACEMENT_ONLY. + +12. The JIT stack should be freed when the low-level stack allocation fails. + +13. In pcre2grep, if the final line in a scanned file is output but does not +end with a newline sequence, add a newline according to the --newline setting. + +14. (?(DEFINE)...) groups were not being handled correctly when checking for +the fixed length of a lookbehind assertion. Such a group within a lookbehind +should be skipped, as it does not contribute to the length of the group. +Instead, the (DEFINE) group was being processed, and if at the end of the +lookbehind, that end was not correctly recognized. Errors such as "lookbehind +assertion is not fixed length" and also "internal error: bad code value in +parsed_skip()" could result. + +15. Put a limit of 1000 on recursive calls in pcre2_study() when searching +nested groups for starting code units, in order to avoid stack overflow issues. +If the limit is reached, it just gives up trying for this optimization. + +16. The control verb chain list must always be restored when exiting from a +recurse function in JIT. + +17. Fix a crash which occurs when the character type of an invalid UTF +character is decoded in JIT. + +18. Changes in many areas of the code so that when Unicode is supported and +PCRE2_UCP is set without PCRE2_UTF, Unicode character properties are used for +upper/lower case computations on characters whose code points are greater than +127. + +19. The function for checking UTF-16 validity was returning an incorrect offset +for the start of the error when a high surrogate was not followed by a valid +low surrogate. This caused incorrect behaviour, for example when +PCRE2_MATCH_INVALID_UTF was set and a match started immediately following the +invalid high surrogate, such as /aa/ matching "\x{d800}aa". + +20. If a DEFINE group immediately preceded a lookbehind assertion, the pattern +could be mis-compiled and therefore not match correctly. This is the example +that found this: /(?(DEFINE)(?bar))(? has been raised to +50, (b) the new --om-capture option changes the limit, (c) an error is raised +if -o asks for a group that is above the limit. + +12. The quantifier {1} was always being ignored, but this is incorrect when it +is made possessive and applied to an item in parentheses, because a +parenthesized item may contain multiple branches or other backtracking points, +for example /(a|ab){1}+c/ or /(a+){1}+a/. + +13. For partial matches, pcre2test was always showing the maximum lookbehind +characters, flagged with "<", which is misleading when the lookbehind didn't +actually look behind the start (because it was later in the pattern). Showing +all consulted preceding characters for partial matches is now controlled by the +existing "allusedtext" modifier and, as for complete matches, this facility is +available only for non-JIT matching, because JIT does not maintain the first +and last consulted characters. + +14. DFA matching (using pcre2_dfa_match()) was not recognising a partial match +if the end of the subject was encountered in a lookahead (conditional or +otherwise), an atomic group, or a recursion. + +15. Give error if pcre2test -t, -T, -tm or -TM is given an argument of zero. + +16. Check for integer overflow when computing lookbehind lengths. Fixes +Clusterfuzz issue 15636. + +17. Implemented non-atomic positive lookaround assertions. + +18. If a lookbehind contained a lookahead that contained another lookbehind +within it, the nested lookbehind was not correctly processed. For example, if +/(?<=(?=(?<=a)))b/ was matched to "ab" it gave no match instead of matching +"b". + +19. Implemented pcre2_get_match_data_size(). + +20. Two alterations to partial matching: + + (a) The definition of a partial match is slightly changed: if a pattern + contains any lookbehinds, an empty partial match may be given, because this + is another situation where adding characters to the current subject can + lead to a full match. Example: /c*+(?<=[bc])/ with subject "ab". + + (b) Similarly, if a pattern could match an empty string, an empty partial + match may be given. Example: /(?![ab]).*/ with subject "ab". This case + applies only to PCRE2_PARTIAL_HARD. + + (c) An empty string partial hard match can be returned for \z and \Z as it + is documented that they shouldn't match. + +21. A branch that started with (*ACCEPT) was not being recognized as one that +could match an empty string. + +22. Corrected pcre2_set_character_tables() tables data type: was const unsigned +char * instead of const uint8_t *, as generated by pcre2_maketables(). + +23. Upgraded to Unicode 12.1.0. + +24. Add -jitfast command line option to pcre2test (to make all the jit options +available directly). + +25. Make pcre2test -C show if libreadline or libedit is supported. + +26. If the length of one branch of a group exceeded 65535 (the maximum value +that is remembered as a minimum length), the whole group's length was +incorrectly recorded as 65535, leading to incorrect "no match" when start-up +optimizations were in force. + +27. The "rightmost consulted character" value was not always correct; in +particular, if a pattern ended with a negative lookahead, characters that were +inspected in that lookahead were not included. + +28. Add the pcre2_maketables_free() function. + +29. The start-up optimization that looks for a unique initial matching +code unit in the interpretive engines uses memchr() in 8-bit mode. When the +search is caseless, it was doing so inefficiently, which ended up slowing down +the match drastically when the subject was very long. The revised code (a) +remembers if one case is not found, so it never repeats the search for that +case after a bumpalong and (b) when one case has been found, it searches only +up to that position for an earlier occurrence of the other case. This fix +applies to both interpretive pcre2_match() and to pcre2_dfa_match(). + +30. While scanning to find the minimum length of a group, if any branch has +minimum length zero, there is no need to scan any subsequent branches (a small +compile-time performance improvement). + +31. Installed a .gitignore file on a user's suggestion. When using the svn +repository with git (through git svn) this helps keep it tidy. + +32. Add underflow check in JIT which may occur when the value of subject +string pointer is close to 0. + +33. Arrange for classes such as [Aa] which contain just the two cases of the +same character, to be treated as a single caseless character. This causes the +first and required code unit optimizations to kick in where relevant. + +34. Improve the bitmap of starting bytes for positive classes that include wide +characters, but no property types, in UTF-8 mode. Previously, on encountering +such a class, the bits for all bytes greater than \xc4 were set, thus +specifying any character with codepoint >= 0x100. Now the only bits that are +set are for the relevant bytes that start the wide characters. This can give a +noticeable performance improvement. + +35. If the bitmap of starting code units contains only 1 or 2 bits, replace it +with a single starting code unit (1 bit) or a caseless single starting code +unit if the two relevant characters are case-partners. This is particularly +relevant to the 8-bit library, though it applies to all. It can give a +performance boost for patterns such as [Ww]ord and (word|WORD). However, this +optimization doesn't happen if there is a "required" code unit of the same +value (because the search for a "required" code unit starts at the match start +for non-unique first code unit patterns, but after a unique first code unit, +and patterns such as a*a need the former action). + +36. Small patch to pcre2posix.c to set the erroroffset field to -1 immediately +after a successful compile, instead of at the start of matching to avoid a +sanitizer complaint (regexec is supposed to be thread safe). + +37. Add NEON vectorization to JIT to speed up matching of first character and +pairs of characters on ARM64 CPUs. + +38. If a non-ASCII character was the first in a starting assertion in a +caseless match, the "first code unit" optimization did not get the casing +right, and the assertion failed to match a character in the other case if it +did not start with the same code unit. + +39. Fixed the incorrect computation of jump sizes on x86 CPUs in JIT. A masking +operation was incorrectly removed in r1136. Reported by Ralf Junker. + + +Version 10.33 16-April-2019 +--------------------------- + +1. Added "allvector" to pcre2test to make it easy to check the part of the +ovector that shouldn't be changed, in particular after substitute and failed or +partial matches. + +2. Fix subject buffer overread in JIT when UTF is disabled and \X or \R has +a greater than 1 fixed quantifier. This issue was found by Yunho Kim. + +3. Added support for callouts from pcre2_substitute(). After 10.33-RC1, but +prior to release, fixed a bug that caused a crash if pcre2_substitute() was +called with a NULL match context. + +4. The POSIX functions are now all called pcre2_regcomp() etc., with wrapper +functions that use the standard POSIX names. However, in pcre2posix.h the POSIX +names are defined as macros. This should help avoid linking with the wrong +library in some environments while still exporting the POSIX names for +pre-existing programs that use them. (The Debian alternative names are also +defined as macros, but not documented.) + +5. Fix an xclass matching issue in JIT. + +6. Implement PCRE2_EXTRA_ESCAPED_CR_IS_LF (see Bugzilla 2315). + +7. Implement the Perl 5.28 experimental alphabetic names for atomic groups and +lookaround assertions, for example, (*pla:...) and (*atomic:...). These are +characterized by a lower case letter following (* and to simplify coding for +this, the character tables created by pcre2_maketables() were updated to add a +new "is lower case letter" bit. At the same time, the now unused "is +hexadecimal digit" bit was removed. The default tables in +src/pcre2_chartables.c.dist are updated. + +8. Implement the new Perl "script run" features (*script_run:...) and +(*atomic_script_run:...) aka (*sr:...) and (*asr:...). + +9. Fixed two typos in change 22 for 10.21, which added special handling for +ranges such as a-z in EBCDIC environments. The original code probably never +worked, though there were no bug reports. + +10. Implement PCRE2_COPY_MATCHED_SUBJECT for pcre2_match() (including JIT via +pcre2_match()) and pcre2_dfa_match(), but *not* the pcre2_jit_match() fast +path. Also, when a match fails, set the subject field in the match data to NULL +for tidiness - none of the substring extractors should reference this after +match failure. + +11. If a pattern started with a subroutine call that had a quantifier with a +minimum of zero, an incorrect "match must start with this character" could be +recorded. Example: /(?&xxx)*ABC(?XYZ)/ would (incorrectly) expect 'A' to +be the first character of a match. + +12. The heap limit checking code in pcre2_dfa_match() could suffer from +overflow if the heap limit was set very large. This could cause incorrect "heap +limit exceeded" errors. + +13. Add "kibibytes" to the heap limit output from pcre2test -C to make the +units clear. + +14. Add a call to pcre2_jit_free_unused_memory() in pcre2grep, for tidiness. + +15. Updated the VMS-specific code in pcre2test on the advice of a VMS user. + +16. Removed the unnecessary inclusion of stdint.h (or inttypes.h) from +pcre2_internal.h as it is now included by pcre2.h. Also, change 17 for 10.32 +below was unnecessarily complicated, as inttypes.h is a Standard C header, +which is defined to be a superset of stdint.h. Instead of conditionally +including stdint.h or inttypes.h, pcre2.h now unconditionally includes +inttypes.h. This supports environments that do not have stdint.h but do have +inttypes.h, which are known to exist. A note in the autotools documentation +says (November 2018) that there are none known that are the other way round. + +17. Added --disable-percent-zt to "configure" (and equivalent to CMake) to +forcibly disable the use of %zu and %td in formatting strings because there is +at least one version of VMS that claims to be C99 but does not support these +modifiers. + +18. Added --disable-pcre2grep-callout-fork, which restricts the callout support +in pcre2grep to the inbuilt echo facility. This may be useful in environments +that do not support fork(). + +19. Fix two instances of <= 0 being applied to unsigned integers (the VMS +compiler complains). + +20. Added "fork" support for VMS to pcre2grep, for running an external program +via a string callout. + +21. Improve MAP_JIT flag usage on MacOS. Patch by Rich Siegel. + +22. If a pattern started with (*MARK), (*COMMIT), (*PRUNE), (*SKIP), or (*THEN) +followed by ^ it was not recognized as anchored. + +23. The RunGrepTest script used to cut out the test of NUL characters for +Solaris and MacOS as printf and sed can't handle them. It seems that the *BSD +systems can't either. I've inverted the test so that only those OS that are +known to work (currently only Linux) try to run this test. + +24. Some tests in RunGrepTest appended to testtrygrep from two different file +descriptors instead of redirecting stderr to stdout. This worked on Linux, but +it was reported not to on other systems, causing the tests to fail. + +25. In the RunTest script, make the test for stack setting use the same value +for the stack as it needs for -bigstack. + +26. Insert a cast in pcre2_dfa_match.c to suppress a compiler warning. + +26. With PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL set, escape sequences such as \s +which are valid in character classes, but not as the end of ranges, were being +treated as literals. An example is [_-\s] (but not [\s-_] because that gave an +error at the *start* of a range). Now an "invalid range" error is given +independently of PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL. + +27. Related to 26 above, PCRE2_BAD_ESCAPE_IS_LITERAL was affecting known escape +sequences such as \eX when they appeared invalidly in a character class. Now +the option applies only to unrecognized or malformed escape sequences. + +28. Fix word boundary in JIT compiler. Patch by Mike Munday. + +29. The pcre2_dfa_match() function was incorrectly handling conditional version +tests such as (?(VERSION>=0)...) when the version test was true. Incorrect +processing or a crash could result. + +30. When PCRE2_UTF is set, allow non-ASCII letters and decimal digits in group +names, as Perl does. There was a small bug in this new code, found by +ClusterFuzz 12950, fixed before release. + +31. Implemented PCRE2_EXTRA_ALT_BSUX to support ECMAScript 6's \u{hhh} +construct. + +32. Compile \p{Any} to be the same as . in DOTALL mode, so that it benefits +from auto-anchoring if \p{Any}* starts a pattern. + +33. Compile invalid UTF check in JIT test when only pcre32 is enabled. + +34. For some time now, CMake has been warning about the setting of policy +CMP0026 to "OLD" in CmakeLists.txt, and hinting that the feature might be +removed in a future version. A request for CMake expertise on the list produced +no result, so I have now hacked CMakeLists.txt along the lines of some changes +I found on the Internet. The new code no longer needs the policy setting, and +it appears to work fine on Linux. + +35. Setting --enable-jit=auto for an out-of-tree build failed because the +source directory wasn't in the search path for AC_TRY_COMPILE always. Patch +from Ross Burton. + +36. Disable SSE2 JIT optimizations in x86 CPUs when SSE2 is not available. +Patch by Guillem Jover. + +37. Changed expressions such as 1<<10 to 1u<<10 in many places because compiler +warnings were reported. + +38. Using the clang compiler with sanitizing options causes runtime complaints +about truncation for statements such as x = ~x when x is an 8-bit value; it +seems to compute ~x as a 32-bit value. Changing such statements to x = 255 ^ x +gets rid of the warnings. There were also two missing casts in pcre2test. + + +Version 10.32 10-September-2018 +------------------------------- + +1. When matching using the REG_STARTEND feature of the POSIX API with a +non-zero starting offset, unset capturing groups with lower numbers than a +group that did capture something were not being correctly returned as "unset" +(that is, with offset values of -1). + +2. When matching using the POSIX API, pcre2test used to omit listing unset +groups altogether. Now it shows those that come before any actual captures as +"", as happens for non-POSIX matching. + +3. Running "pcre2test -C" always stated "\R matches CR, LF, or CRLF only", +whatever the build configuration was. It now correctly says "\R matches all +Unicode newlines" in the default case when --enable-bsr-anycrlf has not been +specified. Similarly, running "pcre2test -C bsr" never produced the result +ANY. + +4. Matching the pattern /(*UTF)\C[^\v]+\x80/ against an 8-bit string containing +multi-code-unit characters caused bad behaviour and possibly a crash. This +issue was fixed for other kinds of repeat in release 10.20 by change 19, but +repeating character classes were overlooked. + +5. pcre2grep now supports the inclusion of binary zeros in patterns that are +read from files via the -f option. + +6. A small fix to pcre2grep to avoid compiler warnings for -Wformat-overflow=2. + +7. Added --enable-jit=auto support to configure.ac. + +8. Added some dummy variables to the heapframe structure in 16-bit and 32-bit +modes for the benefit of m68k, where pointers can be 16-bit aligned. The +dummies force 32-bit alignment and this ensures that the structure is a +multiple of PCRE2_SIZE, a requirement that is tested at compile time. In other +architectures, alignment requirements take care of this automatically. + +9. When returning an error from pcre2_pattern_convert(), ensure the error +offset is set zero for early errors. + +10. A number of patches for Windows support from Daniel Richard G: + + (a) List of error numbers in Runtest.bat corrected (it was not the same as in + Runtest). + + (b) pcre2grep snprintf() workaround as used elsewhere in the tree. + + (c) Support for non-C99 snprintf() that returns -1 in the overflow case. + +11. Minor tidy of pcre2_dfa_match() code. + +12. Refactored pcre2_dfa_match() so that the internal recursive calls no longer +use the stack for local workspace and local ovectors. Instead, an initial block +of stack is reserved, but if this is insufficient, heap memory is used. The +heap limit parameter now applies to pcre2_dfa_match(). + +13. If a "find limits" test of DFA matching in pcre2test resulted in too many +matches for the ovector, no matches were displayed. + +14. Removed an occurrence of ctrl/Z from test 6 because Windows treats it as +EOF. The test looks to have come from a fuzzer. + +15. If PCRE2 was built with a default match limit a lot greater than the +default default of 10 000 000, some JIT tests of the match limit no longer +failed. All such tests now set 10 000 000 as the upper limit. + +16. Another Windows related patch for pcregrep to ensure that WIN32 is +undefined under Cygwin. + +17. Test for the presence of stdint.h and inttypes.h in configure and CMake and +include whichever exists (stdint preferred) instead of unconditionally +including stdint. This makes life easier for old and non-standard systems. + +18. Further changes to improve portability, especially to old and or non- +standard systems: + + (a) Put all printf arguments in RunGrepTest into single, not double, quotes, + and use \0 not \x00 for binary zero. + + (b) Avoid the use of C++ (i.e. BCPL) // comments. + + (c) Parameterize the use of %zu in pcre2test to make it like %td. For both of + these now, if using MSVC or a standard C before C99, %lu is used with a + cast if necessary. + +19. Applied a contributed patch to CMakeLists.txt to increase the stack size +when linking pcre2test with MSVC. This gets rid of a stack overflow error in +the standard set of tests. + +20. Output a warning in pcre2test when ignoring the "altglobal" modifier when +it is given with the "replace" modifier. + +21. In both pcre2test and pcre2_substitute(), with global matching, a pattern +that matched an empty string, but never at the starting match offset, was not +handled in a Perl-compatible way. The pattern /(a(*:1))(?>b)(*SKIP:1)x|.*/ matched against "abc", where the *SKIP +shouldn't find a MARK (because is in an atomic group), but it did. + +26. Upgraded the perltest.sh script: (1) #pattern lines can now be used to set +a list of modifiers for all subsequent patterns - only those that the script +recognizes are meaningful; (2) #subject lines can be used to set or unset a +default "mark" modifier; (3) Unsupported #command lines give a warning when +they are ignored; (4) Mark data is output only if the "mark" modifier is +present. + +27. (*ACCEPT:ARG), (*FAIL:ARG), and (*COMMIT:ARG) are now supported. + +28. A (*MARK) name was not being passed back for positive assertions that were +terminated by (*ACCEPT). + +29. Add support for \N{U+dddd}, but only in Unicode mode. + +30. Add support for (?^) for unsetting all imnsx options. + +31. The PCRE2_EXTENDED (/x) option only ever discarded space characters whose +code point was less than 256 and that were recognized by the lookup table +generated by pcre2_maketables(), which uses isspace() to identify white space. +Now, when Unicode support is compiled, PCRE2_EXTENDED also discards U+0085, +U+200E, U+200F, U+2028, and U+2029, which are additional characters defined by +Unicode as "Pattern White Space". This makes PCRE2 compatible with Perl. + +32. In certain circumstances, option settings within patterns were not being +correctly processed. For example, the pattern /((?i)A)(?m)B/ incorrectly +matched "ab". (The (?m) setting lost the fact that (?i) should be reset at the +end of its group during the parse process, but without another setting such as +(?m) the compile phase got it right.) This bug was introduced by the +refactoring in release 10.23. + +33. PCRE2 uses bcopy() if available when memmove() is not, and it used just to +define memmove() as function call to bcopy(). This hasn't been tested for a +long time because in pcre2test the result of memmove() was being used, whereas +bcopy() doesn't return a result. This feature is now refactored always to call +an emulation function when there is no memmove(). The emulation makes use of +bcopy() when available. + +34. When serializing a pattern, set the memctl, executable_jit, and tables +fields (that is, all the fields that contain pointers) to zeros so that the +result of serializing is always the same. These fields are re-set when the +pattern is deserialized. + +35. In a pattern such as /[^\x{100}-\x{ffff}]*[\x80-\xff]/ which has a repeated +negative class with no characters less than 0x100 followed by a positive class +with only characters less than 0x100, the first class was incorrectly being +auto-possessified, causing incorrect match failures. + +36. Removed the character type bit ctype_meta, which dates from PCRE1 and is +not used in PCRE2. + +37. Tidied up unnecessarily complicated macros used in the escapes table. + +38. Since 10.21, the new testoutput8-16-4 file has accidentally been omitted +from distribution tarballs, owing to a typo in Makefile.am which had +testoutput8-16-3 twice. Now fixed. + +39. If the only branch in a conditional subpattern was anchored, the whole +subpattern was treated as anchored, when it should not have been, since the +assumed empty second branch cannot be anchored. Demonstrated by test patterns +such as /(?(1)^())b/ or /(?(?=^))b/. + +40. A repeated conditional subpattern that could match an empty string was +always assumed to be unanchored. Now it is checked just like any other +repeated conditional subpattern, and can be found to be anchored if the minimum +quantifier is one or more. I can't see much use for a repeated anchored +pattern, but the behaviour is now consistent. + +41. Minor addition to pcre2_jit_compile.c to avoid static analyzer complaint +(for an event that could never occur but you had to have external information +to know that). + +42. If before the first match in a file that was being searched by pcre2grep +there was a line that was sufficiently long to cause the input buffer to be +expanded, the variable holding the location of the end of the previous match +was being adjusted incorrectly, and could cause an overflow warning from a code +sanitizer. However, as the value is used only to print pending "after" lines +when the next match is reached (and there are no such lines in this case) this +bug could do no damage. + + +Version 10.31 12-February-2018 +------------------------------ + +1. Fix typo (missing ]) in VMS code in pcre2test.c. + +2. Replace the replicated code for matching extended Unicode grapheme sequences +(which got a lot more complicated by change 10.30/49) by a single subroutine +that is called by both pcre2_match() and pcre2_dfa_match(). + +3. Add idempotent guard to pcre2_internal.h. + +4. Add new pcre2_config() options: PCRE2_CONFIG_NEVER_BACKSLASH_C and +PCRE2_CONFIG_COMPILED_WIDTHS. + +5. Cut out \C tests in the JIT regression tests when NEVER_BACKSLASH_C is +defined (e.g. by --enable-never-backslash-C). + +6. Defined public names for all the pcre2_compile() error numbers, and used +the public names in pcre2_convert.c. + +7. Fixed a small memory leak in pcre2test (convert contexts). + +8. Added two casts to compile.c and one to match.c to avoid compiler warnings. + +9. Added code to pcre2grep when compiled under VMS to set the symbol +PCRE2GREP_RC to the exit status, because VMS does not distinguish between +exit(0) and exit(1). + +10. Added the -LM (list modifiers) option to pcre2test. Also made -C complain +about a bad option only if the following argument item does not start with a +hyphen. + +11. pcre2grep was truncating components of file names to 128 characters when +processing files with the -r option, and also (some very odd code) truncating +path names to 512 characters. There is now a check on the absolute length of +full path file names, which may be up to 2047 characters long. + +12. When an assertion contained (*ACCEPT) it caused all open capturing groups +to be closed (as for a non-assertion ACCEPT), which was wrong and could lead to +misbehaviour for subsequent references to groups that started outside the +assertion. ACCEPT in an assertion now closes only those groups that were +started within that assertion. Fixes oss-fuzz issues 3852 and 3891. + +13. Multiline matching in pcre2grep was misbehaving if the pattern matched +within a line, and then matched again at the end of the line and over into +subsequent lines. Behaviour was different with and without colouring, and +sometimes context lines were incorrectly printed and/or line endings were lost. +All these issues should now be fixed. + +14. If --line-buffered was specified for pcre2grep when input was from a +compressed file (.gz or .bz2) a segfault occurred. (Line buffering should be +ignored for compressed files.) + +15. Although pcre2_jit_match checks whether the pattern is compiled +in a given mode, it was also expected that at least one mode is available. +This is fixed and pcre2_jit_match returns with PCRE2_ERROR_JIT_BADOPTION +when the pattern is not optimized by JIT at all. + +16. The line number and related variables such as match counts in pcre2grep +were all int variables, causing overflow when files with more than 2147483647 +lines were processed (assuming 32-bit ints). They have all been changed to +unsigned long ints. + +17. If a backreference with a minimum repeat count of zero was first in a +pattern, apart from assertions, an incorrect first matching character could be +recorded. For example, for the pattern /(?=(a))\1?b/, "b" was incorrectly set +as the first character of a match. + +18. Characters in a leading positive assertion are considered for recording a +first character of a match when the rest of the pattern does not provide one. +However, a character in a non-assertive group within a leading assertion such +as in the pattern /(?=(a))\1?b/ caused this process to fail. This was an +infelicity rather than an outright bug, because it did not affect the result of +a match, just its speed. (In fact, in this case, the starting 'a' was +subsequently picked up in the study.) + +19. A minor tidy in pcre2_match(): making all PCRE2_ERROR_ returns use "return" +instead of "RRETURN" saves unwinding the backtracks in these cases (only one +didn't). + +20. Allocate a single callout block on the stack at the start of pcre2_match() +and set its never-changing fields once only. Do the same for pcre2_dfa_match(). + +21. Save the extra compile options (set in the compile context) with the +compiled pattern (they were not previously saved), add PCRE2_INFO_EXTRAOPTIONS +to retrieve them, and update pcre2test to show them. + +22. Added PCRE2_CALLOUT_STARTMATCH and PCRE2_CALLOUT_BACKTRACK bits to a new +field callout_flags in callout blocks. The bits are set by pcre2_match(), but +not by JIT or pcre2_dfa_match(). Their settings are shown in pcre2test callouts +if the callout_extra subject modifier is set. These bits are provided to help +with tracking how a backtracking match is proceeding. + +23. Updated the pcre2demo.c demonstration program, which was missing the extra +code for -g that handles the case when \K in an assertion causes the match to +end at the original start point. Also arranged for it to detect when \K causes +the end of a match to be before its start. + +24. Similar to 23 above, strange things (including loops) could happen in +pcre2grep when \K was used in an assertion when --colour was used or in +multiline mode. The "end at original start point" bug is fixed, and if the end +point is found to be before the start point, they are swapped. + +25. When PCRE2_FIRSTLINE without PCRE2_NO_START_OPTIMIZE was used in non-JIT +matching (both pcre2_match() and pcre2_dfa_match()) and the matched string +started with the first code unit of a newline sequence, matching failed because +it was not tried at the newline. + +26. Code for giving up a non-partial match after failing to find a starting +code unit anywhere in the subject was missing when searching for one of a +number of code units (the bitmap case) in both pcre2_match() and +pcre2_dfa_match(). This was a missing optimization rather than a bug. + +27. Tidied up the ACROSSCHAR macro to be like FORWARDCHAR and BACKCHAR, using a +pointer argument rather than a code unit value. This should not have affected +the generated code. + +28. The JIT compiler has been updated. + +29. Avoid pointer overflow for unset captures in pcre2_substring_list_get(). +This could not actually cause a crash because it was always used in a memcpy() +call with zero length. + +30. Some internal structures have a variable-length ovector[] as their last +element. Their actual memory is obtained dynamically, giving an ovector of +appropriate length. However, they are defined in the structure as +ovector[NUMBER], where NUMBER is large so that array bound checkers don't +grumble. The value of NUMBER was 10000, but a fuzzer exceeded 5000 capturing +groups, making the ovector larger than this. The number has been increased to +131072, which allows for the maximum number of captures (65535) plus the +overall match. This fixes oss-fuzz issue 5415. + +31. Auto-possessification at the end of a capturing group was dependent on what +follows the group (e.g. /(a+)b/ would auto-possessify the a+) but this caused +incorrect behaviour when the group was called recursively from elsewhere in the +pattern where something different might follow. This bug is an unforseen +consequence of change #1 for 10.30 - the implementation of backtracking into +recursions. Iterators at the ends of capturing groups are no longer considered +for auto-possessification if the pattern contains any recursions. Fixes +Bugzilla #2232. + + +Version 10.30 14-August-2017 +---------------------------- + +1. The main interpreter, pcre2_match(), has been refactored into a new version +that does not use recursive function calls (and therefore the stack) for +remembering backtracking positions. This makes --disable-stack-for-recursion a +NOOP. The new implementation allows backtracking into recursive group calls in +patterns, making it more compatible with Perl, and also fixes some other +hard-to-do issues such as #1887 in Bugzilla. The code is also cleaner because +the old code had a number of fudges to try to reduce stack usage. It seems to +run no slower than the old code. + +A number of bugs in the refactored code were subsequently fixed during testing +before release, but after the code was made available in the repository. These +bugs were never in fully released code, but are noted here for the record. + + (a) If a pattern had fewer capturing parentheses than the ovector supplied in + the match data block, a memory error (detectable by ASAN) occurred after + a match, because the external block was being set from non-existent + internal ovector fields. Fixes oss-fuzz issue 781. + + (b) A pattern with very many capturing parentheses (when the internal frame + size was greater than the initial frame vector on the stack) caused a + crash. A vector on the heap is now set up at the start of matching if the + vector on the stack is not big enough to handle at least 10 frames. + Fixes oss-fuzz issue 783. + + (c) Handling of (*VERB)s in recursions was wrong in some cases. + + (d) Captures in negative assertions that were used as conditions were not + happening if the assertion matched via (*ACCEPT). + + (e) Mark values were not being passed out of recursions. + + (f) Refactor some code in do_callout() to avoid picky compiler warnings about + negative indices. Fixes oss-fuzz issue 1454. + + (g) Similarly refactor the way the variable length ovector is addressed for + similar reasons. Fixes oss-fuzz issue 1465. + +2. Now that pcre2_match() no longer uses recursive function calls (see above), +the "match limit recursion" value seems misnamed. It still exists, and limits +the depth of tree that is searched. To avoid future confusion, it has been +renamed as "depth limit" in all relevant places (--with-depth-limit, +(*LIMIT_DEPTH), pcre2_set_depth_limit(), etc) but the old names are still +available for backwards compatibility. + +3. Hardened pcre2test so as to reduce the number of bugs reported by fuzzers: + + (a) Check for malloc failures when getting memory for the ovector (POSIX) or + the match data block (non-POSIX). + +4. In the 32-bit library in non-UTF mode, an attempt to find a Unicode property +for a character with a code point greater than 0x10ffff (the Unicode maximum) +caused a crash. + +5. If a lookbehind assertion that contained a back reference to a group +appearing later in the pattern was compiled with the PCRE2_ANCHORED option, +undefined actions (often a segmentation fault) could occur, depending on what +other options were set. An example assertion is (?" should be ">=" in opcode check in pcre2_auto_possess.c. + (b) Added some casts to avoid "suspicious implicit sign extension". + (c) Resource leaks in pcre2test in rare error cases. + (d) Avoid warning for never-use case OP_TABLE_LENGTH which is just a fudge + for checking at compile time that tables are the right size. + (e) Add missing "fall through" comment. + +29. Implemented PCRE2_EXTENDED_MORE and related /xx and (?xx) features. + +30. Implement (?n: for PCRE2_NO_AUTO_CAPTURE, because Perl now has this. + +31. If more than one of "push", "pushcopy", or "pushtablescopy" were set in +pcre2test, a crash could occur. + +32. Make -bigstack in RunTest allocate a 64MiB stack (instead of 16MiB) so +that all the tests can run with clang's sanitizing options. + +33. Implement extra compile options in the compile context and add the first +one: PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES. + +34. Implement newline type PCRE2_NEWLINE_NUL. + +35. A lookbehind assertion that had a zero-length branch caused undefined +behaviour when processed by pcre2_dfa_match(). This is oss-fuzz issue 1859. + +36. The match limit value now also applies to pcre2_dfa_match() as there are +patterns that can use up a lot of resources without necessarily recursing very +deeply. (Compare item 10.23/36.) This should fix oss-fuzz #1761. + +37. Implement PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL. + +38. Fix returned offsets from regexec() when REG_STARTEND is used with a +starting offset greater than zero. + +39. Implement REG_PEND (GNU extension) for the POSIX wrapper. + +40. Implement the subject_literal modifier in pcre2test, and allow jitstack on +pattern lines. + +41. Implement PCRE2_LITERAL and use it to support REG_NOSPEC. + +42. Implement PCRE2_EXTRA_MATCH_LINE and PCRE2_EXTRA_MATCH_WORD for the benefit +of pcre2grep. + +43. Re-implement pcre2grep's -F, -w, and -x options using PCRE2_LITERAL, +PCRE2_EXTRA_MATCH_WORD, and PCRE2_EXTRA_MATCH_LINE. This fixes two bugs: + + (a) The -F option did not work for fixed strings containing \E. + (b) The -w option did not work for patterns with multiple branches. + +44. Added configuration options for the SELinux compatible execmem allocator in +JIT. + +45. Increased the limit for searching for a "must be present" code unit in +subjects from 1000 to 2000 for 8-bit searches, since they use memchr() and are +much faster. + +46. Arrange for anchored patterns to record and use "first code unit" data, +because this can give a fast "no match" without searching for a "required code +unit". Previously only non-anchored patterns did this. + +47. Upgraded the Unicode tables from Unicode 8.0.0 to Unicode 10.0.0. + +48. Add the callout_no_where modifier to pcre2test. + +49. Update extended grapheme breaking rules to the latest set that are in +Unicode Standard Annex #29. + +50. Added experimental foreign pattern conversion facilities +(pcre2_pattern_convert() and friends). + +51. Change the macro FWRITE, used in pcre2grep, to FWRITE_IGNORE because FWRITE +is defined in a system header in cygwin. Also modified some of the #ifdefs in +pcre2grep related to Windows and Cygwin support. + +52. Change 3(g) for 10.23 was a bit too zealous. If a hyphen that follows a +character class is the last character in the class, Perl does not give a +warning. PCRE2 now also treats this as a literal. + +53. Related to 52, though PCRE2 was throwing an error for [[:digit:]-X] it was +not doing so for [\d-X] (and similar escapes), as is documented. + +54. Fixed a MIPS issue in the JIT compiler reported by Joshua Kinard. + +55. Fixed a "maybe uninitialized" warning for class_uchardata in \p handling in +pcre2_compile() which could never actually trigger (code should have been cut +out when Unicode support is disabled). + + +Version 10.23 14-February-2017 +------------------------------ + +1. Extended pcre2test with the utf8_input modifier so that it is able to +generate all possible 16-bit and 32-bit code unit values in non-UTF modes. + +2. In any wide-character mode (8-bit UTF or any 16-bit or 32-bit mode), without +PCRE2_UCP set, a negative character type such as \D in a positive class should +cause all characters greater than 255 to match, whatever else is in the class. +There was a bug that caused this not to happen if a Unicode property item was +added to such a class, for example [\D\P{Nd}] or [\W\pL]. + +3. There has been a major re-factoring of the pcre2_compile.c file. Most syntax +checking is now done in the pre-pass that identifies capturing groups. This has +reduced the amount of duplication and made the code tidier. While doing this, +some minor bugs and Perl incompatibilities were fixed, including: + + (a) \Q\E in the middle of a quantifier such as A+\Q\E+ is now ignored instead + of giving an invalid quantifier error. + + (b) {0} can now be used after a group in a lookbehind assertion; previously + this caused an "assertion is not fixed length" error. + + (c) Perl always treats (?(DEFINE) as a "define" group, even if a group with + the name "DEFINE" exists. PCRE2 now does likewise. + + (d) A recursion condition test such as (?(R2)...) must now refer to an + existing subpattern. + + (e) A conditional recursion test such as (?(R)...) misbehaved if there was a + group whose name began with "R". + + (f) When testing zero-terminated patterns under valgrind, the terminating + zero is now marked "no access". This catches bugs that would otherwise + show up only with non-zero-terminated patterns. + + (g) A hyphen appearing immediately after a POSIX character class (for example + /[[:ascii:]-z]/) now generates an error. Perl does accept this as a + literal, but gives a warning, so it seems best to fail it in PCRE. + + (h) An empty \Q\E sequence may appear after a callout that precedes an + assertion condition (it is, of course, ignored). + +One effect of the refactoring is that some error numbers and messages have +changed, and the pattern offset given for compiling errors is not always the +right-most character that has been read. In particular, for a variable-length +lookbehind assertion it now points to the start of the assertion. Another +change is that when a callout appears before a group, the "length of next +pattern item" that is passed now just gives the length of the opening +parenthesis item, not the length of the whole group. A length of zero is now +given only for a callout at the end of the pattern. Automatic callouts are no +longer inserted before and after explicit callouts in the pattern. + +A number of bugs in the refactored code were subsequently fixed during testing +before release, but after the code was made available in the repository. Many +of the bugs were discovered by fuzzing testing. Several of them were related to +the change from assuming a zero-terminated pattern (which previously had +required non-zero terminated strings to be copied). These bugs were never in +fully released code, but are noted here for the record. + + (a) An overall recursion such as (?0) inside a lookbehind assertion was not + being diagnosed as an error. + + (b) In utf mode, the length of a *MARK (or other verb) name was being checked + in characters instead of code units, which could lead to bad code being + compiled, leading to unpredictable behaviour. + + (c) In extended /x mode, characters whose code was greater than 255 caused + a lookup outside one of the global tables. A similar bug existed for wide + characters in *VERB names. + + (d) The amount of memory needed for a compiled pattern was miscalculated if a + lookbehind contained more than one toplevel branch and the first branch + was of length zero. + + (e) In UTF-8 or UTF-16 modes with PCRE2_EXTENDED (/x) set and a non-zero- + terminated pattern, if a # comment ran on to the end of the pattern, one + or more code units past the end were being read. + + (f) An unterminated repeat at the end of a non-zero-terminated pattern (e.g. + "{2,2") could cause reading beyond the pattern. + + (g) When reading a callout string, if the end delimiter was at the end of the + pattern one further code unit was read. + + (h) An unterminated number after \g' could cause reading beyond the pattern. + + (i) An insufficient memory size was being computed for compiling with + PCRE2_AUTO_CALLOUT. + + (j) A conditional group with an assertion condition used more memory than was + allowed for it during parsing, so too many of them could therefore + overrun a buffer. + + (k) If parsing a pattern exactly filled the buffer, the internal test for + overrun did not check when the final META_END item was added. + + (l) If a lookbehind contained a subroutine call, and the called group + contained an option setting such as (?s), and the PCRE2_ANCHORED option + was set, unpredictable behaviour could occur. The underlying bug was + incorrect code and insufficient checking while searching for the end of + the called subroutine in the parsed pattern. + + (m) Quantifiers following (*VERB)s were not being diagnosed as errors. + + (n) The use of \Q...\E in a (*VERB) name when PCRE2_ALT_VERBNAMES and + PCRE2_AUTO_CALLOUT were both specified caused undetermined behaviour. + + (o) If \Q was preceded by a quantified item, and the following \E was + followed by '?' or '+', and there was at least one literal character + between them, an internal error "unexpected repeat" occurred (example: + /.+\QX\E+/). + + (p) A buffer overflow could occur while sorting the names in the group name + list (depending on the order in which the names were seen). + + (q) A conditional group that started with a callout was not doing the right + check for a following assertion, leading to compiling bad code. Example: + /(?(C'XX))?!XX/ + + (r) If a character whose code point was greater than 0xffff appeared within + a lookbehind that was within another lookbehind, the calculation of the + lookbehind length went wrong and could provoke an internal error. + + (t) The sequence \E- or \Q\E- after a POSIX class in a character class caused + an internal error. Now the hyphen is treated as a literal. + +4. Back references are now permitted in lookbehind assertions when there are +no duplicated group numbers (that is, (?| has not been used), and, if the +reference is by name, there is only one group of that name. The referenced +group must, of course be of fixed length. + +5. pcre2test has been upgraded so that, when run under valgrind with valgrind +support enabled, reading past the end of the pattern is detected, both when +compiling and during callout processing. + +6. \g{+} (e.g. \g{+2} ) is now supported. It is a "forward back +reference" and can be useful in repetitions (compare \g{-} ). Perl does +not recognize this syntax. + +7. Automatic callouts are no longer generated before and after callouts in the +pattern. + +8. When pcre2test was outputting information from a callout, the caret indicator +for the current position in the subject line was incorrect if it was after an +escape sequence for a character whose code point was greater than \x{ff}. + +9. Change 19 for 10.22 had a typo (PCRE_STATIC_RUNTIME should be +PCRE2_STATIC_RUNTIME). Fix from David Gaussmann. + +10. Added --max-buffer-size to pcre2grep, to allow for automatic buffer +expansion when long lines are encountered. Original patch by Dmitry +Cherniachenko. + +11. If pcre2grep was compiled with JIT support, but the library was compiled +without it (something that neither ./configure nor CMake allow, but it can be +done by editing config.h), pcre2grep was giving a JIT error. Now it detects +this situation and does not try to use JIT. + +12. Added some "const" qualifiers to variables in pcre2grep. + +13. Added Dmitry Cherniachenko's patch for colouring output in Windows +(untested by me). Also, look for GREP_COLOUR or GREP_COLOR if the environment +variables PCRE2GREP_COLOUR and PCRE2GREP_COLOR are not found. + +14. Add the -t (grand total) option to pcre2grep. + +15. A number of bugs have been mended relating to match start-up optimizations +when the first thing in a pattern is a positive lookahead. These all applied +only when PCRE2_NO_START_OPTIMIZE was *not* set: + + (a) A pattern such as (?=.*X)X$ was incorrectly optimized as if it needed + both an initial 'X' and a following 'X'. + (b) Some patterns starting with an assertion that started with .* were + incorrectly optimized as having to match at the start of the subject or + after a newline. There are cases where this is not true, for example, + (?=.*[A-Z])(?=.{8,16})(?!.*[\s]) matches after the start in lines that + start with spaces. Starting .* in an assertion is no longer taken as an + indication of matching at the start (or after a newline). + +16. The "offset" modifier in pcre2test was not being ignored (as documented) +when the POSIX API was in use. + +17. Added --enable-fuzz-support to "configure", causing an non-installed +library containing a test function that can be called by fuzzers to be +compiled. A non-installed binary to run the test function locally, called +pcre2fuzzcheck is also compiled. + +18. A pattern with PCRE2_DOTALL (/s) set but not PCRE2_NO_DOTSTAR_ANCHOR, and +which started with .* inside a positive lookahead was incorrectly being +compiled as implicitly anchored. + +19. Removed all instances of "register" declarations, as they are considered +obsolete these days and in any case had become very haphazard. + +20. Add strerror() to pcre2test for failed file opening. + +21. Make pcre2test -C list valgrind support when it is enabled. + +22. Add the use_length modifier to pcre2test. + +23. Fix an off-by-one bug in pcre2test for the list of names for 'get' and +'copy' modifiers. + +24. Add PCRE2_CALL_CONVENTION into the prototype declarations in pcre2.h as it +is apparently needed there as well as in the function definitions. (Why did +nobody ask for this in PCRE1?) + +25. Change the _PCRE2_H and _PCRE2_UCP_H guard macros in the header files to +PCRE2_H_IDEMPOTENT_GUARD and PCRE2_UCP_H_IDEMPOTENT_GUARD to be more standard +compliant and unique. + +26. pcre2-config --libs-posix was listing -lpcre2posix instead of +-lpcre2-posix. Also, the CMake build process was building the library with the +wrong name. + +27. In pcre2test, give some offset information for errors in hex patterns. +This uses the C99 formatting sequence %td, except for MSVC which doesn't +support it - %lu is used instead. + +28. Implemented pcre2_code_copy_with_tables(), and added pushtablescopy to +pcre2test for testing it. + +29. Fix small memory leak in pcre2test. + +30. Fix out-of-bounds read for partial matching of /./ against an empty string +when the newline type is CRLF. + +31. Fix a bug in pcre2test that caused a crash when a locale was set either in +the current pattern or a previous one and a wide character was matched. + +32. The appearance of \p, \P, or \X in a substitution string when +PCRE2_SUBSTITUTE_EXTENDED was set caused a segmentation fault (NULL +dereference). + +33. If the starting offset was specified as greater than the subject length in +a call to pcre2_substitute() an out-of-bounds memory reference could occur. + +34. When PCRE2 was compiled to use the heap instead of the stack for recursive +calls to match(), a repeated minimizing caseless back reference, or a +maximizing one where the two cases had different numbers of code units, +followed by a caseful back reference, could lose the caselessness of the first +repeated back reference (example: /(Z)(a)\2{1,2}?(?-i)\1X/i should match ZaAAZX +but didn't). + +35. When a pattern is too complicated, PCRE2 gives up trying to find a minimum +matching length and just records zero. Typically this happens when there are +too many nested or recursive back references. If the limit was reached in +certain recursive cases it failed to be triggered and an internal error could +be the result. + +36. The pcre2_dfa_match() function now takes note of the recursion limit for +the internal recursive calls that are used for lookrounds and recursions within +the pattern. + +37. More refactoring has got rid of the internal could_be_empty_branch() +function (around 400 lines of code, including comments) by keeping track of +could-be-emptiness as the pattern is compiled instead of scanning compiled +groups. (This would have been much harder before the refactoring of #3 above.) +This lifts a restriction on the number of branches in a group (more than about +1100 would give "pattern is too complicated"). + +38. Add the "-ac" command line option to pcre2test as a synonym for "-pattern +auto_callout". + +39. In a library with Unicode support, incorrect data was compiled for a +pattern with PCRE2_UCP set without PCRE2_UTF if a class required all wide +characters to match (for example, /[\s[:^ascii:]]/). + +40. The callout_error modifier has been added to pcre2test to make it possible +to return PCRE2_ERROR_CALLOUT from a callout. + +41. A minor change to pcre2grep: colour reset is now "[0m" instead of +"[00m". + +42. The limit in the auto-possessification code that was intended to catch +overly-complicated patterns and not spend too much time auto-possessifying was +being reset too often, resulting in very long compile times for some patterns. +Now such patterns are no longer completely auto-possessified. + +43. Applied Jason Hood's revised patch for RunTest.bat. + +44. Added a new Windows script RunGrepTest.bat, courtesy of Jason Hood. + +45. Minor cosmetic fix to pcre2test: move a variable that is not used under +Windows into the "not Windows" code. + +46. Applied Jason Hood's patches to upgrade pcre2grep under Windows and tidy +some of the code: + + * normalised the Windows condition by ensuring WIN32 is defined; + * enables the callout feature under Windows; + * adds globbing (Microsoft's implementation expands quoted args), + using a tweaked opendirectory; + * implements the is_*_tty functions for Windows; + * --color=always will write the ANSI sequences to file; + * add sequences 4 (underline works on Win10) and 5 (blink as bright + background, relatively standard on DOS/Win); + * remove the (char *) casts for the now-const strings; + * remove GREP_COLOUR (grep's command line allowed the 'u', but not + the environment), parsing GREP_COLORS instead; + * uses the current colour if not set, rather than black; + * add print_match for the undefined case; + * fixes a typo. + +In addition, colour settings containing anything other than digits and +semicolon are ignored, and the colour controls are no longer output for empty +strings. + +47. Detecting patterns that are too large inside the length-measuring loop +saves processing ridiculously long patterns to their end. + +48. Ignore PCRE2_CASELESS when processing \h, \H, \v, and \V in classes as it +just wastes time. In the UTF case it can also produce redundant entries in +XCLASS lists caused by characters with multiple other cases and pairs of +characters in the same "not-x" sublists. + +49. A pattern such as /(?=(a\K))/ can report the end of the match being before +its start; pcre2test was not handling this correctly when using the POSIX +interface (it was OK with the native interface). + +50. In pcre2grep, ignore all JIT compile errors. This means that pcre2grep will +continue to work, falling back to interpretation if anything goes wrong with +JIT. + +51. Applied patches from Christian Persch to configure.ac to make use of the +AC_USE_SYSTEM_EXTENSIONS macro and to test for functions used by the JIT +modules. + +52. Minor fixes to pcre2grep from Jason Hood: + * fixed some spacing; + * Windows doesn't usually use single quotes, so I've added a define + to use appropriate quotes [in an example]; + * LC_ALL was displayed as "LCC_ALL"; + * numbers 11, 12 & 13 should end in "th"; + * use double quotes in usage message. + +53. When autopossessifying, skip empty branches without recursion, to reduce +stack usage for the benefit of clang with -fsanitize-address, which uses huge +stack frames. Example pattern: /X?(R||){3335}/. Fixes oss-fuzz issue 553. + +54. A pattern with very many explicit back references to a group that is a long +way from the start of the pattern could take a long time to compile because +searching for the referenced group in order to find the minimum length was +being done repeatedly. Now up to 128 group minimum lengths are cached and the +attempt to find a minimum length is abandoned if there is a back reference to a +group whose number is greater than 128. (In that case, the pattern is so +complicated that this optimization probably isn't worth it.) This fixes +oss-fuzz issue 557. + +55. Issue 32 for 10.22 below was not correctly fixed. If pcre2grep in multiline +mode with --only-matching matched several lines, it restarted scanning at the +next line instead of moving on to the end of the matched string, which can be +several lines after the start. + +56. Applied Jason Hood's new patch for RunGrepTest.bat that updates it in line +with updates to the non-Windows version. + + + +Version 10.22 29-July-2016 +-------------------------- + +1. Applied Jason Hood's patches to RunTest.bat and testdata/wintestoutput3 +to fix problems with running the tests under Windows. + +2. Implemented a facility for quoting literal characters within hexadecimal +patterns in pcre2test, to make it easier to create patterns with just a few +non-printing characters. + +3. Binary zeros are not supported in pcre2test input files. It now detects them +and gives an error. + +4. Updated the valgrind parameters in RunTest: (a) changed smc-check=all to +smc-check=all-non-file; (b) changed obj:* in the suppression file to obj:??? so +that it matches only unknown objects. + +5. Updated the maintenance script maint/ManyConfigTests to make it easier to +select individual groups of tests. + +6. When the POSIX wrapper function regcomp() is called, the REG_NOSUB option +used to set PCRE2_NO_AUTO_CAPTURE when calling pcre2_compile(). However, this +disables the use of back references (and subroutine calls), which are supported +by other implementations of regcomp() with RE_NOSUB. Therefore, REG_NOSUB no +longer causes PCRE2_NO_AUTO_CAPTURE to be set, though it still ignores nmatch +and pmatch when regexec() is called. + +7. Because of 6 above, pcre2test has been modified with a new modifier called +posix_nosub, to call regcomp() with REG_NOSUB. Previously the no_auto_capture +modifier had this effect. That option is now ignored when the POSIX API is in +use. + +8. Minor tidies to the pcre2demo.c sample program, including more comments +about its 8-bit-ness. + +9. Detect unmatched closing parentheses and give the error in the pre-scan +instead of later. Previously the pre-scan carried on and could give a +misleading incorrect error message. For example, /(?J)(?'a'))(?'a')/ gave a +message about invalid duplicate group names. + +10. It has happened that pcre2test was accidentally linked with another POSIX +regex library instead of libpcre2-posix. In this situation, a call to regcomp() +(in the other library) may succeed, returning zero, but of course putting its +own data into the regex_t block. In one example the re_pcre2_code field was +left as NULL, which made pcre2test think it had not got a compiled POSIX regex, +so it treated the next line as another pattern line, resulting in a confusing +error message. A check has been added to pcre2test to see if the data returned +from a successful call of regcomp() are valid for PCRE2's regcomp(). If they +are not, an error message is output and the pcre2test run is abandoned. The +message points out the possibility of a mis-linking. Hopefully this will avoid +some head-scratching the next time this happens. + +11. A pattern such as /(?<=((?C)0))/, which has a callout inside a lookbehind +assertion, caused pcre2test to output a very large number of spaces when the +callout was taken, making the program appearing to loop. + +12. A pattern that included (*ACCEPT) in the middle of a sufficiently deeply +nested set of parentheses of sufficient size caused an overflow of the +compiling workspace (which was diagnosed, but of course is not desirable). + +13. Detect missing closing parentheses during the pre-pass for group +identification. + +14. Changed some integer variable types and put in a number of casts, following +a report of compiler warnings from Visual Studio 2013 and a few tests with +gcc's -Wconversion (which still throws up a lot). + +15. Implemented pcre2_code_copy(), and added pushcopy and #popcopy to pcre2test +for testing it. + +16. Change 66 for 10.21 introduced the use of snprintf() in PCRE2's version of +regerror(). When the error buffer is too small, my version of snprintf() puts a +binary zero in the final byte. Bug #1801 seems to show that other versions do +not do this, leading to bad output from pcre2test when it was checking for +buffer overflow. It no longer assumes a binary zero at the end of a too-small +regerror() buffer. + +17. Fixed typo ("&&" for "&") in pcre2_study(). Fortunately, this could not +actually affect anything, by sheer luck. + +18. Two minor fixes for MSVC compilation: (a) removal of apparently incorrect +"const" qualifiers in pcre2test and (b) defining snprintf as _snprintf for +older MSVC compilers. This has been done both in src/pcre2_internal.h for most +of the library, and also in src/pcre2posix.c, which no longer includes +pcre2_internal.h (see 24 below). + +19. Applied Chris Wilson's patch (Bugzilla #1681) to CMakeLists.txt for MSVC +static compilation. Subsequently applied Chris Wilson's second patch, putting +the first patch under a new option instead of being unconditional when +PCRE_STATIC is set. + +20. Updated pcre2grep to set stdout as binary when run under Windows, so as not +to convert \r\n at the ends of reflected lines into \r\r\n. This required +ensuring that other output that is written to stdout (e.g. file names) uses the +appropriate line terminator: \r\n for Windows, \n otherwise. + +21. When a line is too long for pcre2grep's internal buffer, show the maximum +length in the error message. + +22. Added support for string callouts to pcre2grep (Zoltan's patch with PH +additions). + +23. RunTest.bat was missing a "set type" line for test 22. + +24. The pcre2posix.c file was including pcre2_internal.h, and using some +"private" knowledge of the data structures. This is unnecessary; the code has +been re-factored and no longer includes pcre2_internal.h. + +25. A racing condition is fixed in JIT reported by Mozilla. + +26. Minor code refactor to avoid "array subscript is below array bounds" +compiler warning. + +27. Minor code refactor to avoid "left shift of negative number" warning. + +28. Add a bit more sanity checking to pcre2_serialize_decode() and document +that it expects trusted data. + +29. Fix typo in pcre2_jit_test.c + +30. Due to an oversight, pcre2grep was not making use of JIT when available. +This is now fixed. + +31. The RunGrepTest script is updated to use the valgrind suppressions file +when testing with JIT under valgrind (compare 10.21/51 below). The suppressions +file is updated so that is now the same as for PCRE1: it suppresses the +Memcheck warnings Addr16 and Cond in unknown objects (that is, JIT-compiled +code). Also changed smc-check=all to smc-check=all-non-file as was done for +RunTest (see 4 above). + +32. Implemented the PCRE2_NO_JIT option for pcre2_match(). + +33. Fix typo that gave a compiler error when JIT not supported. + +34. Fix comment describing the returns from find_fixedlength(). + +35. Fix potential negative index in pcre2test. + +36. Calls to pcre2_get_error_message() with error numbers that are never +returned by PCRE2 functions were returning empty strings. Now the error code +PCRE2_ERROR_BADDATA is returned. A facility has been added to pcre2test to +show the texts for given error numbers (i.e. to call pcre2_get_error_message() +and display what it returns) and a few representative error codes are now +checked in RunTest. + +37. Added "&& !defined(__INTEL_COMPILER)" to the test for __GNUC__ in +pcre2_match.c, in anticipation that this is needed for the same reason it was +recently added to pcrecpp.cc in PCRE1. + +38. Using -o with -M in pcre2grep could cause unnecessary repeated output when +the match extended over a line boundary, as it tried to find more matches "on +the same line" - but it was already over the end. + +39. Allow \C in lookbehinds and DFA matching in UTF-32 mode (by converting it +to the same code as '.' when PCRE2_DOTALL is set). + +40. Fix two clang compiler warnings in pcre2test when only one code unit width +is supported. + +41. Upgrade RunTest to automatically re-run test 2 with a large (64MiB) stack +if it fails when running the interpreter with a 16MiB stack (and if changing +the stack size via pcre2test is possible). This avoids having to manually set a +large stack size when testing with clang. + +42. Fix register overwrite in JIT when SSE2 acceleration is enabled. + +43. Detect integer overflow in pcre2test pattern and data repetition counts. + +44. In pcre2test, ignore "allcaptures" after DFA matching. + +45. Fix unaligned accesses on x86. Patch by Marc Mutz. + +46. Fix some more clang compiler warnings. + + +Version 10.21 12-January-2016 +----------------------------- + +1. Improve matching speed of patterns starting with + or * in JIT. + +2. Use memchr() to find the first character in an unanchored match in 8-bit +mode in the interpreter. This gives a significant speed improvement. + +3. Removed a redundant copy of the opcode_possessify table in the +pcre2_auto_possessify.c source. + +4. Fix typos in dftables.c for z/OS. + +5. Change 36 for 10.20 broke the handling of [[:>:]] and [[:<:]] in that +processing them could involve a buffer overflow if the following character was +an opening parenthesis. + +6. Change 36 for 10.20 also introduced a bug in processing this pattern: +/((?x)(*:0))#(?'/. Specifically: if a setting of (?x) was followed by a (*MARK) +setting (which (*:0) is), then (?x) did not get unset at the end of its group +during the scan for named groups, and hence the external # was incorrectly +treated as a comment and the invalid (?' at the end of the pattern was not +diagnosed. This caused a buffer overflow during the real compile. This bug was +discovered by Karl Skomski with the LLVM fuzzer. + +7. Moved the pcre2_find_bracket() function from src/pcre2_compile.c into its +own source module to avoid a circular dependency between src/pcre2_compile.c +and src/pcre2_study.c + +8. A callout with a string argument containing an opening square bracket, for +example /(?C$[$)(?<]/, was incorrectly processed and could provoke a buffer +overflow. This bug was discovered by Karl Skomski with the LLVM fuzzer. + +9. The handling of callouts during the pre-pass for named group identification +has been tightened up. + +10. The quantifier {1} can be ignored, whether greedy, non-greedy, or +possessive. This is a very minor optimization. + +11. A possessively repeated conditional group that could match an empty string, +for example, /(?(R))*+/, was incorrectly compiled. + +12. The Unicode tables have been updated to Unicode 8.0.0 (thanks to Christian +Persch). + +13. An empty comment (?#) in a pattern was incorrectly processed and could +provoke a buffer overflow. This bug was discovered by Karl Skomski with the +LLVM fuzzer. + +14. Fix infinite recursion in the JIT compiler when certain patterns such as +/(?:|a|){100}x/ are analysed. + +15. Some patterns with character classes involving [: and \\ were incorrectly +compiled and could cause reading from uninitialized memory or an incorrect +error diagnosis. Examples are: /[[:\\](?<[::]/ and /[[:\\](?'abc')[a:]. The +first of these bugs was discovered by Karl Skomski with the LLVM fuzzer. + +16. Pathological patterns containing many nested occurrences of [: caused +pcre2_compile() to run for a very long time. This bug was found by the LLVM +fuzzer. + +17. A missing closing parenthesis for a callout with a string argument was not +being diagnosed, possibly leading to a buffer overflow. This bug was found by +the LLVM fuzzer. + +18. A conditional group with only one branch has an implicit empty alternative +branch and must therefore be treated as potentially matching an empty string. + +19. If (?R was followed by - or + incorrect behaviour happened instead of a +diagnostic. This bug was discovered by Karl Skomski with the LLVM fuzzer. + +20. Another bug that was introduced by change 36 for 10.20: conditional groups +whose condition was an assertion preceded by an explicit callout with a string +argument might be incorrectly processed, especially if the string contained \Q. +This bug was discovered by Karl Skomski with the LLVM fuzzer. + +21. Compiling PCRE2 with the sanitize options of clang showed up a number of +very pedantic coding infelicities and a buffer overflow while checking a UTF-8 +string if the final multi-byte UTF-8 character was truncated. + +22. For Perl compatibility in EBCDIC environments, ranges such as a-z in a +class, where both values are literal letters in the same case, omit the +non-letter EBCDIC code points within the range. + +23. Finding the minimum matching length of complex patterns with back +references and/or recursions can take a long time. There is now a cut-off that +gives up trying to find a minimum length when things get too complex. + +24. An optimization has been added that speeds up finding the minimum matching +length for patterns containing repeated capturing groups or recursions. + +25. If a pattern contained a back reference to a group whose number was +duplicated as a result of appearing in a (?|...) group, the computation of the +minimum matching length gave a wrong result, which could cause incorrect "no +match" errors. For such patterns, a minimum matching length cannot at present +be computed. + +26. Added a check for integer overflow in conditions (?() and +(?(R). This omission was discovered by Karl Skomski with the LLVM +fuzzer. + +27. Fixed an issue when \p{Any} inside an xclass did not read the current +character. + +28. If pcre2grep was given the -q option with -c or -l, or when handling a +binary file, it incorrectly wrote output to stdout. + +29. The JIT compiler did not restore the control verb head in case of *THEN +control verbs. This issue was found by Karl Skomski with a custom LLVM fuzzer. + +30. The way recursive references such as (?3) are compiled has been re-written +because the old way was the cause of many issues. Now, conversion of the group +number into a pattern offset does not happen until the pattern has been +completely compiled. This does mean that detection of all infinitely looping +recursions is postponed till match time. In the past, some easy ones were +detected at compile time. This re-writing was done in response to yet another +bug found by the LLVM fuzzer. + +31. A test for a back reference to a non-existent group was missing for items +such as \987. This caused incorrect code to be compiled. This issue was found +by Karl Skomski with a custom LLVM fuzzer. + +32. Error messages for syntax errors following \g and \k were giving inaccurate +offsets in the pattern. + +33. Improve the performance of starting single character repetitions in JIT. + +34. (*LIMIT_MATCH=) now gives an error instead of setting the value to 0. + +35. Error messages for syntax errors in *LIMIT_MATCH and *LIMIT_RECURSION now +give the right offset instead of zero. + +36. The JIT compiler should not check repeats after a {0,1} repeat byte code. +This issue was found by Karl Skomski with a custom LLVM fuzzer. + +37. The JIT compiler should restore the control chain for empty possessive +repeats. This issue was found by Karl Skomski with a custom LLVM fuzzer. + +38. A bug which was introduced by the single character repetition optimization +was fixed. + +39. Match limit check added to recursion. This issue was found by Karl Skomski +with a custom LLVM fuzzer. + +40. Arrange for the UTF check in pcre2_match() and pcre2_dfa_match() to look +only at the part of the subject that is relevant when the starting offset is +non-zero. + +41. Improve first character match in JIT with SSE2 on x86. + +42. Fix two assertion fails in JIT. These issues were found by Karl Skomski +with a custom LLVM fuzzer. + +43. Correct the setting of CMAKE_C_FLAGS in CMakeLists.txt (patch from Roy Ivy +III). + +44. Fix bug in RunTest.bat for new test 14, and adjust the script for the added +test (there are now 20 in total). + +45. Fixed a corner case of range optimization in JIT. + +46. Add the ${*MARK} facility to pcre2_substitute(). + +47. Modifier lists in pcre2test were splitting at spaces without the required +commas. + +48. Implemented PCRE2_ALT_VERBNAMES. + +49. Fixed two issues in JIT. These were found by Karl Skomski with a custom +LLVM fuzzer. + +50. The pcre2test program has been extended by adding the #newline_default +command. This has made it possible to run the standard tests when PCRE2 is +compiled with either CR or CRLF as the default newline convention. As part of +this work, the new command was added to several test files and the testing +scripts were modified. The pcre2grep tests can now also be run when there is no +LF in the default newline convention. + +51. The RunTest script has been modified so that, when JIT is used and valgrind +is specified, a valgrind suppressions file is set up to ignore "Invalid read of +size 16" errors because these are false positives when the hardware supports +the SSE2 instruction set. + +52. It is now possible to have comment lines amid the subject strings in +pcre2test (and perltest.sh) input. + +53. Implemented PCRE2_USE_OFFSET_LIMIT and pcre2_set_offset_limit(). + +54. Add the null_context modifier to pcre2test so that calling pcre2_compile() +and the matching functions with NULL contexts can be tested. + +55. Implemented PCRE2_SUBSTITUTE_EXTENDED. + +56. In a character class such as [\W\p{Any}] where both a negative-type escape +("not a word character") and a property escape were present, the property +escape was being ignored. + +57. Fixed integer overflow for patterns whose minimum matching length is very, +very large. + +58. Implemented --never-backslash-C. + +59. Change 55 above introduced a bug by which certain patterns provoked the +erroneous error "\ at end of pattern". + +60. The special sequences [[:<:]] and [[:>:]] gave rise to incorrect compiling +errors or other strange effects if compiled in UCP mode. Found with libFuzzer +and AddressSanitizer. + +61. Whitespace at the end of a pcre2test pattern line caused a spurious error +message if there were only single-character modifiers. It should be ignored. + +62. The use of PCRE2_NO_AUTO_CAPTURE could cause incorrect compilation results +or segmentation errors for some patterns. Found with libFuzzer and +AddressSanitizer. + +63. Very long names in (*MARK) or (*THEN) etc. items could provoke a buffer +overflow. + +64. Improve error message for overly-complicated patterns. + +65. Implemented an optional replication feature for patterns in pcre2test, to +make it easier to test long repetitive patterns. The tests for 63 above are +converted to use the new feature. + +66. In the POSIX wrapper, if regerror() was given too small a buffer, it could +misbehave. + +67. In pcre2_substitute() in UTF mode, the UTF validity check on the +replacement string was happening before the length setting when the replacement +string was zero-terminated. + +68. In pcre2_substitute() in UTF mode, PCRE2_NO_UTF_CHECK can be set for the +second and subsequent calls to pcre2_match(). + +69. There was no check for integer overflow for a replacement group number in +pcre2_substitute(). An added check for a number greater than the largest group +number in the pattern means this is not now needed. + +70. The PCRE2-specific VERSION condition didn't work correctly if only one +digit was given after the decimal point, or if more than two digits were given. +It now works with one or two digits, and gives a compile time error if more are +given. + +71. In pcre2_substitute() there was the possibility of reading one code unit +beyond the end of the replacement string. + +72. The code for checking a subject's UTF-32 validity for a pattern with a +lookbehind involved an out-of-bounds pointer, which could potentially cause +trouble in some environments. + +73. The maximum lookbehind length was incorrectly calculated for patterns such +as /(?<=(a)(?-1))x/ which have a recursion within a backreference. + +74. Give an error if a lookbehind assertion is longer than 65535 code units. + +75. Give an error in pcre2_substitute() if a match ends before it starts (as a +result of the use of \K). + +76. Check the length of subpattern names and the names in (*MARK:xx) etc. +dynamically to avoid the possibility of integer overflow. + +77. Implement pcre2_set_max_pattern_length() so that programs can restrict the +size of patterns that they are prepared to handle. + +78. (*NO_AUTO_POSSESS) was not working. + +79. Adding group information caching improves the speed of compiling when +checking whether a group has a fixed length and/or could match an empty string, +especially when recursion or subroutine calls are involved. However, this +cannot be used when (?| is present in the pattern because the same number may +be used for groups of different sizes. To catch runaway patterns in this +situation, counts have been introduced to the functions that scan for empty +branches or compute fixed lengths. + +80. Allow for the possibility of the size of the nest_save structure not being +a factor of the size of the compiling workspace (it currently is). + +81. Check for integer overflow in minimum length calculation and cap it at +65535. + +82. Small optimizations in code for finding the minimum matching length. + +83. Lock out configuring for EBCDIC with non-8-bit libraries. + +84. Test for error code <= 0 in regerror(). + +85. Check for too many replacements (more than INT_MAX) in pcre2_substitute(). + +86. Avoid the possibility of computing with an out-of-bounds pointer (though +not dereferencing it) while handling lookbehind assertions. + +87. Failure to get memory for the match data in regcomp() is now given as a +regcomp() error instead of waiting for regexec() to pick it up. + +88. In pcre2_substitute(), ensure that CRLF is not split when it is a valid +newline sequence. + +89. Paranoid check in regcomp() for bad error code from pcre2_compile(). + +90. Run test 8 (internal offsets and code sizes) for link sizes 3 and 4 as well +as for link size 2. + +91. Document that JIT has a limit on pattern size, and give more information +about JIT compile failures in pcre2test. + +92. Implement PCRE2_INFO_HASBACKSLASHC. + +93. Re-arrange valgrind support code in pcre2test to avoid spurious reports +with JIT (possibly caused by SSE2?). + +94. Support offset_limit in JIT. + +95. A sequence such as [[:punct:]b] that is, a POSIX character class followed +by a single ASCII character in a class item, was incorrectly compiled in UCP +mode. The POSIX class got lost, but only if the single character followed it. + +96. [:punct:] in UCP mode was matching some characters in the range 128-255 +that should not have been matched. + +97. If [:^ascii:] or [:^xdigit:] are present in a non-negated class, all +characters with code points greater than 255 are in the class. When a Unicode +property was also in the class (if PCRE2_UCP is set, escapes such as \w are +turned into Unicode properties), wide characters were not correctly handled, +and could fail to match. + +98. In pcre2test, make the "startoffset" modifier a synonym of "offset", +because it sets the "startoffset" parameter for pcre2_match(). + +99. If PCRE2_AUTO_CALLOUT was set on a pattern that had a (?# comment between +an item and its qualifier (for example, A(?#comment)?B) pcre2_compile() +misbehaved. This bug was found by the LLVM fuzzer. + +100. The error for an invalid UTF pattern string always gave the code unit +offset as zero instead of where the invalidity was found. + +101. Further to 97 above, negated classes such as [^[:^ascii:]\d] were also not +working correctly in UCP mode. + +102. Similar to 99 above, if an isolated \E was present between an item and its +qualifier when PCRE2_AUTO_CALLOUT was set, pcre2_compile() misbehaved. This bug +was found by the LLVM fuzzer. + +103. The POSIX wrapper function regexec() crashed if the option REG_STARTEND +was set when the pmatch argument was NULL. It now returns REG_INVARG. + +104. Allow for up to 32-bit numbers in the ordin() function in pcre2grep. + +105. An empty \Q\E sequence between an item and its qualifier caused +pcre2_compile() to misbehave when auto callouts were enabled. This bug +was found by the LLVM fuzzer. + +106. If both PCRE2_ALT_VERBNAMES and PCRE2_EXTENDED were set, and a (*MARK) or +other verb "name" ended with whitespace immediately before the closing +parenthesis, pcre2_compile() misbehaved. Example: /(*:abc )/, but only when +both those options were set. + +107. In a number of places pcre2_compile() was not handling NULL characters +correctly, and pcre2test with the "bincode" modifier was not always correctly +displaying fields containing NULLS: + + (a) Within /x extended #-comments + (b) Within the "name" part of (*MARK) and other *verbs + (c) Within the text argument of a callout + +108. If a pattern that was compiled with PCRE2_EXTENDED started with white +space or a #-type comment that was followed by (?-x), which turns off +PCRE2_EXTENDED, and there was no subsequent (?x) to turn it on again, +pcre2_compile() assumed that (?-x) applied to the whole pattern and +consequently mis-compiled it. This bug was found by the LLVM fuzzer. The fix +for this bug means that a setting of any of the (?imsxJU) options at the start +of a pattern is no longer transferred to the options that are returned by +PCRE2_INFO_ALLOPTIONS. In fact, this was an anachronism that should have +changed when the effects of those options were all moved to compile time. + +109. An escaped closing parenthesis in the "name" part of a (*verb) when +PCRE2_ALT_VERBNAMES was set caused pcre2_compile() to malfunction. This bug +was found by the LLVM fuzzer. + +110. Implemented PCRE2_SUBSTITUTE_UNSET_EMPTY, and updated pcre2test to make it +possible to test it. + +111. "Harden" pcre2test against ridiculously large values in modifiers and +command line arguments. + +112. Implemented PCRE2_SUBSTITUTE_UNKNOWN_UNSET and PCRE2_SUBSTITUTE_OVERFLOW_ +LENGTH. + +113. Fix printing of *MARK names that contain binary zeroes in pcre2test. + + +Version 10.20 30-June-2015 +-------------------------- + +1. Callouts with string arguments have been added. + +2. Assertion code generator in JIT has been optimized. + +3. The invalid pattern (?(?C) has a missing assertion condition at the end. The +pcre2_compile() function read past the end of the input before diagnosing an +error. This bug was discovered by the LLVM fuzzer. + +4. Implemented pcre2_callout_enumerate(). + +5. Fix JIT compilation of conditional blocks whose assertion is converted to +(*FAIL). E.g: /(?(?!))/. + +6. The pattern /(?(?!)^)/ caused references to random memory. This bug was +discovered by the LLVM fuzzer. + +7. The assertion (?!) is optimized to (*FAIL). This was not handled correctly +when this assertion was used as a condition, for example (?(?!)a|b). In +pcre2_match() it worked by luck; in pcre2_dfa_match() it gave an incorrect +error about an unsupported item. + +8. For some types of pattern, for example /Z*(|d*){216}/, the auto- +possessification code could take exponential time to complete. A recursion +depth limit of 1000 has been imposed to limit the resources used by this +optimization. This infelicity was discovered by the LLVM fuzzer. + +9. A pattern such as /(*UTF)[\S\V\H]/, which contains a negated special class +such as \S in non-UCP mode, explicit wide characters (> 255) can be ignored +because \S ensures they are all in the class. The code for doing this was +interacting badly with the code for computing the amount of space needed to +compile the pattern, leading to a buffer overflow. This bug was discovered by +the LLVM fuzzer. + +10. A pattern such as /((?2)+)((?1))/ which has mutual recursion nested inside +other kinds of group caused stack overflow at compile time. This bug was +discovered by the LLVM fuzzer. + +11. A pattern such as /(?1)(?#?'){8}(a)/ which had a parenthesized comment +between a subroutine call and its quantifier was incorrectly compiled, leading +to buffer overflow or other errors. This bug was discovered by the LLVM fuzzer. + +12. The illegal pattern /(?(?.*!.*)?)/ was not being diagnosed as missing an +assertion after (?(. The code was failing to check the character after (?(?< +for the ! or = that would indicate a lookbehind assertion. This bug was +discovered by the LLVM fuzzer. + +13. A pattern such as /X((?2)()*+){2}+/ which has a possessive quantifier with +a fixed maximum following a group that contains a subroutine reference was +incorrectly compiled and could trigger buffer overflow. This bug was discovered +by the LLVM fuzzer. + +14. Negative relative recursive references such as (?-7) to non-existent +subpatterns were not being diagnosed and could lead to unpredictable behaviour. +This bug was discovered by the LLVM fuzzer. + +15. The bug fixed in 14 was due to an integer variable that was unsigned when +it should have been signed. Some other "int" variables, having been checked, +have either been changed to uint32_t or commented as "must be signed". + +16. A mutual recursion within a lookbehind assertion such as (?<=((?2))((?1))) +caused a stack overflow instead of the diagnosis of a non-fixed length +lookbehind assertion. This bug was discovered by the LLVM fuzzer. + +17. The use of \K in a positive lookbehind assertion in a non-anchored pattern +(e.g. /(?<=\Ka)/) could make pcre2grep loop. + +18. There was a similar problem to 17 in pcre2test for global matches, though +the code there did catch the loop. + +19. If a greedy quantified \X was preceded by \C in UTF mode (e.g. \C\X*), +and a subsequent item in the pattern caused a non-match, backtracking over the +repeated \X did not stop, but carried on past the start of the subject, causing +reference to random memory and/or a segfault. There were also some other cases +where backtracking after \C could crash. This set of bugs was discovered by the +LLVM fuzzer. + +20. The function for finding the minimum length of a matching string could take +a very long time if mutual recursion was present many times in a pattern, for +example, /((?2){73}(?2))((?1))/. A better mutual recursion detection method has +been implemented. This infelicity was discovered by the LLVM fuzzer. + +21. Implemented PCRE2_NEVER_BACKSLASH_C. + +22. The feature for string replication in pcre2test could read from freed +memory if the replication required a buffer to be extended, and it was not +working properly in 16-bit and 32-bit modes. This issue was discovered by a +fuzzer: see http://lcamtuf.coredump.cx/afl/. + +23. Added the PCRE2_ALT_CIRCUMFLEX option. + +24. Adjust the treatment of \8 and \9 to be the same as the current Perl +behaviour. + +25. Static linking against the PCRE2 library using the pkg-config module was +failing on missing pthread symbols. + +26. If a group that contained a recursive back reference also contained a +forward reference subroutine call followed by a non-forward-reference +subroutine call, for example /.((?2)(?R)\1)()/, pcre2_compile() failed to +compile correct code, leading to undefined behaviour or an internally detected +error. This bug was discovered by the LLVM fuzzer. + +27. Quantification of certain items (e.g. atomic back references) could cause +incorrect code to be compiled when recursive forward references were involved. +For example, in this pattern: /(?1)()((((((\1++))\x85)+)|))/. This bug was +discovered by the LLVM fuzzer. + +28. A repeated conditional group whose condition was a reference by name caused +a buffer overflow if there was more than one group with the given name. This +bug was discovered by the LLVM fuzzer. + +29. A recursive back reference by name within a group that had the same name as +another group caused a buffer overflow. For example: /(?J)(?'d'(?'d'\g{d}))/. +This bug was discovered by the LLVM fuzzer. + +30. A forward reference by name to a group whose number is the same as the +current group, for example in this pattern: /(?|(\k'Pm')|(?'Pm'))/, caused a +buffer overflow at compile time. This bug was discovered by the LLVM fuzzer. + +31. Fix -fsanitize=undefined warnings for left shifts of 1 by 31 (it treats 1 +as an int; fixed by writing it as 1u). + +32. Fix pcre2grep compile when -std=c99 is used with gcc, though it still gives +a warning for "fileno" unless -std=gnu99 us used. + +33. A lookbehind assertion within a set of mutually recursive subpatterns could +provoke a buffer overflow. This bug was discovered by the LLVM fuzzer. + +34. Give an error for an empty subpattern name such as (?''). + +35. Make pcre2test give an error if a pattern that follows #forbud_utf contains +\P, \p, or \X. + +36. The way named subpatterns are handled has been refactored. There is now a +pre-pass over the regex which does nothing other than identify named +subpatterns and count the total captures. This means that information about +named patterns is known before the rest of the compile. In particular, it means +that forward references can be checked as they are encountered. Previously, the +code for handling forward references was contorted and led to several errors in +computing the memory requirements for some patterns, leading to buffer +overflows. + +37. There was no check for integer overflow in subroutine calls such as (?123). + +38. The table entry for \l in EBCDIC environments was incorrect, leading to its +being treated as a literal 'l' instead of causing an error. + +39. If a non-capturing group containing a conditional group that could match +an empty string was repeated, it was not identified as matching an empty string +itself. For example: /^(?:(?(1)x|)+)+$()/. + +40. In an EBCDIC environment, pcretest was mishandling the escape sequences +\a and \e in test subject lines. + +41. In an EBCDIC environment, \a in a pattern was converted to the ASCII +instead of the EBCDIC value. + +42. The handling of \c in an EBCDIC environment has been revised so that it is +now compatible with the specification in Perl's perlebcdic page. + +43. Single character repetition in JIT has been improved. 20-30% speedup +was achieved on certain patterns. + +44. The EBCDIC character 0x41 is a non-breaking space, equivalent to 0xa0 in +ASCII/Unicode. This has now been added to the list of characters that are +recognized as white space in EBCDIC. + +45. When PCRE2 was compiled without Unicode support, the use of \p and \P gave +an error (correctly) when used outside a class, but did not give an error +within a class. + +46. \h within a class was incorrectly compiled in EBCDIC environments. + +47. JIT should return with error when the compiled pattern requires +more stack space than the maximum. + +48. Fixed a memory leak in pcre2grep when a locale is set. + + +Version 10.10 06-March-2015 +--------------------------- + +1. When a pattern is compiled, it remembers the highest back reference so that +when matching, if the ovector is too small, extra memory can be obtained to +use instead. A conditional subpattern whose condition is a check on a capture +having happened, such as, for example in the pattern /^(?:(a)|b)(?(1)A|B)/, is +another kind of back reference, but it was not setting the highest +backreference number. This mattered only if pcre2_match() was called with an +ovector that was too small to hold the capture, and there was no other kind of +back reference (a situation which is probably quite rare). The effect of the +bug was that the condition was always treated as FALSE when the capture could +not be consulted, leading to a incorrect behaviour by pcre2_match(). This bug +has been fixed. + +2. Functions for serialization and deserialization of sets of compiled patterns +have been added. + +3. The value that is returned by PCRE2_INFO_SIZE has been corrected to remove +excess code units at the end of the data block that may occasionally occur if +the code for calculating the size over-estimates. This change stops the +serialization code copying uninitialized data, to which valgrind objects. The +documentation of PCRE2_INFO_SIZE was incorrect in stating that the size did not +include the general overhead. This has been corrected. + +4. All code units in every slot in the table of group names are now set, again +in order to avoid accessing uninitialized data when serializing. + +5. The (*NO_JIT) feature is implemented. + +6. If a bug that caused pcre2_compile() to use more memory than allocated was +triggered when using valgrind, the code in (3) above passed a stupidly large +value to valgrind. This caused a crash instead of an "internal error" return. + +7. A reference to a duplicated named group (either a back reference or a test +for being set in a conditional) that occurred in a part of the pattern where +PCRE2_DUPNAMES was not set caused the amount of memory needed for the pattern +to be incorrectly calculated, leading to overwriting. + +8. A mutually recursive set of back references such as (\2)(\1) caused a +segfault at compile time (while trying to find the minimum matching length). +The infinite loop is now broken (with the minimum length unset, that is, zero). + +9. If an assertion that was used as a condition was quantified with a minimum +of zero, matching went wrong. In particular, if the whole group had unlimited +repetition and could match an empty string, a segfault was likely. The pattern +(?(?=0)?)+ is an example that caused this. Perl allows assertions to be +quantified, but not if they are being used as conditions, so the above pattern +is faulted by Perl. PCRE2 has now been changed so that it also rejects such +patterns. + +10. The error message for an invalid quantifier has been changed from "nothing +to repeat" to "quantifier does not follow a repeatable item". + +11. If a bad UTF string is compiled with NO_UTF_CHECK, it may succeed, but +scanning the compiled pattern in subsequent auto-possessification can get out +of step and lead to an unknown opcode. Previously this could have caused an +infinite loop. Now it generates an "internal error" error. This is a tidyup, +not a bug fix; passing bad UTF with NO_UTF_CHECK is documented as having an +undefined outcome. + +12. A UTF pattern containing a "not" match of a non-ASCII character and a +subroutine reference could loop at compile time. Example: /[^\xff]((?1))/. + +13. The locale test (RunTest 3) has been upgraded. It now checks that a locale +that is found in the output of "locale -a" can actually be set by pcre2test +before it is accepted. Previously, in an environment where a locale was listed +but would not set (an example does exist), the test would "pass" without +actually doing anything. Also the fr_CA locale has been added to the list of +locales that can be used. + +14. Fixed a bug in pcre2_substitute(). If a replacement string ended in a +capturing group number without parentheses, the last character was incorrectly +literally included at the end of the replacement string. + +15. A possessive capturing group such as (a)*+ with a minimum repeat of zero +failed to allow the zero-repeat case if pcre2_match() was called with an +ovector too small to capture the group. + +16. Improved error message in pcre2test when setting the stack size (-S) fails. + +17. Fixed two bugs in CMakeLists.txt: (1) Some lines had got lost in the +transfer from PCRE1, meaning that CMake configuration failed if "build tests" +was selected. (2) The file src/pcre2_serialize.c had not been added to the list +of PCRE2 sources, which caused a failure to build pcre2test. + +18. Fixed typo in pcre2_serialize.c (DECL instead of DEFN) that causes problems +only on Windows. + +19. Use binary input when reading back saved serialized patterns in pcre2test. + +20. Added RunTest.bat for running the tests under Windows. + +21. "make distclean" was not removing config.h, a file that may be created for +use with CMake. + +22. A pattern such as "((?2){0,1999}())?", which has a group containing a +forward reference repeated a large (but limited) number of times within a +repeated outer group that has a zero minimum quantifier, caused incorrect code +to be compiled, leading to the error "internal error: previously-checked +referenced subpattern not found" when an incorrect memory address was read. +This bug was reported as "heap overflow", discovered by Kai Lu of Fortinet's +FortiGuard Labs. (Added 24-March-2015: CVE-2015-2325 was given to this.) + +23. A pattern such as "((?+1)(\1))/" containing a forward reference subroutine +call within a group that also contained a recursive back reference caused +incorrect code to be compiled. This bug was reported as "heap overflow", +discovered by Kai Lu of Fortinet's FortiGuard Labs. (Added 24-March-2015: +CVE-2015-2326 was given to this.) + +24. Computing the size of the JIT read-only data in advance has been a source +of various issues, and new ones are still appear unfortunately. To fix +existing and future issues, size computation is eliminated from the code, +and replaced by on-demand memory allocation. + +25. A pattern such as /(?i)[A-`]/, where characters in the other case are +adjacent to the end of the range, and the range contained characters with more +than one other case, caused incorrect behaviour when compiled in UTF mode. In +that example, the range a-j was left out of the class. + + +Version 10.00 05-January-2015 +----------------------------- + +Version 10.00 is the first release of PCRE2, a revised API for the PCRE +library. Changes prior to 10.00 are logged in the ChangeLog file for the old +API, up to item 20 for release 8.36. + +The code of the library was heavily revised as part of the new API +implementation. Details of each and every modification were not individually +logged. In addition to the API changes, the following changes were made. They +are either new functionality, or bug fixes and other noticeable changes of +behaviour that were implemented after the code had been forked. + +1. Including Unicode support at build time is now enabled by default, but it +can optionally be disabled. It is not enabled by default at run time (no +change). + +2. The test program, now called pcre2test, was re-specified and almost +completely re-written. Its input is not compatible with input for pcretest. + +3. Patterns may start with (*NOTEMPTY) or (*NOTEMPTY_ATSTART) to set the +PCRE2_NOTEMPTY or PCRE2_NOTEMPTY_ATSTART options for every subject line that is +matched by that pattern. + +4. For the benefit of those who use PCRE2 via some other application, that is, +not writing the function calls themselves, it is possible to check the PCRE2 +version by matching a pattern such as /(?(VERSION>=10)yes|no)/ against a +string such as "yesno". + +5. There are case-equivalent Unicode characters whose encodings use different +numbers of code units in UTF-8. U+023A and U+2C65 are one example. (It is +theoretically possible for this to happen in UTF-16 too.) If a backreference to +a group containing one of these characters was greedily repeated, and during +the match a backtrack occurred, the subject might be backtracked by the wrong +number of code units. For example, if /^(\x{23a})\1*(.)/ is matched caselessly +(and in UTF-8 mode) against "\x{23a}\x{2c65}\x{2c65}\x{2c65}", group 2 should +capture the final character, which is the three bytes E2, B1, and A5 in UTF-8. +Incorrect backtracking meant that group 2 captured only the last two bytes. +This bug has been fixed; the new code is slower, but it is used only when the +strings matched by the repetition are not all the same length. + +6.

PCRE2 is a library based on the original PCRE library, +but with a revised (and incompatible) API. To avoid confusion, the original +library is referred to as PCRE1 below. For information about testing PCRE2, see +the pcre2test documentation and the comment at the head of the RunTest file. + +PCRE1 releases were up to 8.3x when PCRE2 was developed, and later bug fix +releases carried on the 8.xx series, up to the final 8.45 release. PCRE2 +releases started at 10.00 to avoid confusion with PCRE1. + + +Historical note 1 +----------------- + +Many years ago I implemented some regular expression functions to an algorithm +suggested by Martin Richards. The rather simple patterns were not Unix-like in +form, and were quite restricted in what they could do by comparison with Perl. +The interesting part about the algorithm was that the amount of space required +to hold the compiled form of an expression was known in advance. The code to +apply an expression did not operate by backtracking, as the original Henry +Spencer code and current PCRE2 and Perl code does, but instead checked all +possibilities simultaneously by keeping a list of current states and checking +all of them as it advanced through the subject string. In the terminology of +Jeffrey Friedl's book, it was a "DFA algorithm", though it was not a +traditional Finite State Machine (FSM). When the pattern was all used up, all +remaining states were possible matches, and the one matching the longest subset +of the subject string was chosen. This did not necessarily maximize the +individual wild portions of the pattern, as is expected in Unix and Perl-style +regular expressions. + + +Historical note 2 +----------------- + +By contrast, the code originally written by Henry Spencer (which was +subsequently heavily modified for Perl) compiles the expression twice: once in +a dummy mode in order to find out how much store will be needed, and then for +real. (The Perl version may or may not still do this; I'm talking about the +original library.) The execution function operates by backtracking and +maximizing (or, optionally, minimizing, in Perl) the amount of the subject that +matches individual wild portions of the pattern. This is an "NFA algorithm" in +Friedl's terminology. + + +OK, here's the real stuff +------------------------- + +For the set of functions that formed the original PCRE1 library in 1997 (which +are unrelated to those mentioned above), I tried at first to invent an +algorithm that used an amount of store bounded by a multiple of the number of +characters in the pattern, to save on compiling time. However, because of the +greater complexity in Perl regular expressions, I couldn't do this, even though +the then current Perl 5.004 patterns were much simpler than those supported +nowadays. In any case, a first pass through the pattern is helpful for other +reasons. + + +Support for 16-bit and 32-bit data strings +------------------------------------------- + +The PCRE2 library can be compiled in any combination of 8-bit, 16-bit or 32-bit +modes, creating up to three different libraries. In the description that +follows, the word "short" is used for a 16-bit data quantity, and the phrase +"code unit" is used for a quantity that is a byte in 8-bit mode, a short in +16-bit mode and a 32-bit word in 32-bit mode. The names of PCRE2 functions are +given in generic form, without the _8, _16, or _32 suffix. + + +Computing the memory requirement: how it was +-------------------------------------------- + +Up to and including release 6.7, PCRE1 worked by running a very degenerate +first pass to calculate a maximum memory requirement, and then a second pass to +do the real compile - which might use a bit less than the predicted amount of +memory. The idea was that this would turn out faster than the Henry Spencer +code because the first pass is degenerate and the second pass can just store +stuff straight into memory, which it knows is big enough. + + +Computing the memory requirement: how it is +------------------------------------------- + +By the time I was working on a potential 6.8 release, the degenerate first pass +had become very complicated and hard to maintain. Indeed one of the early +things I did for 6.8 was to fix Yet Another Bug in the memory computation. Then +I had a flash of inspiration as to how I could run the real compile function in +a "fake" mode that enables it to compute how much memory it would need, while +in most cases only ever using a small amount of working memory, and without too +many tests of the mode that might slow it down. So I refactored the compiling +functions to work this way. This got rid of about 600 lines of source and made +further maintenance and development easier. As this was such a major change, I +never released 6.8, instead upping the number to 7.0 (other quite major changes +were also present in the 7.0 release). + +A side effect of this work was that the previous limit of 200 on the nesting +depth of parentheses was removed. However, there was a downside: compiling ran +more slowly than before (30% or more, depending on the pattern) because it now +did a full analysis of the pattern. My hope was that this would not be a big +issue, and in the event, nobody has commented on it. + +At release 8.34, a limit on the nesting depth of parentheses was re-introduced +(default 250, settable at build time) so as to put a limit on the amount of +system stack used by the compile function, which uses recursive function calls +for nested parenthesized groups. This is a safety feature for environments with +small stacks where the patterns are provided by users. + + +Yet another pattern scan +------------------------ + +History repeated itself for PCRE2 release 10.20. A number of bugs relating to +named subpatterns had been discovered by fuzzers. Most of these were related to +the handling of forward references when it was not known if the named group was +unique. (References to non-unique names use a different opcode and more +memory.) The use of duplicate group numbers (the (?| facility) also caused +issues. + +To get around these problems I adopted a new approach by adding a third pass +over the pattern (really a "pre-pass"), which did nothing other than identify +all the named subpatterns and their corresponding group numbers. This means +that the actual compile (both the memory-computing dummy run and the real +compile) has full knowledge of group names and numbers throughout. Several +dozen lines of messy code were eliminated, though the new pre-pass was not +short. In particular, parsing and skipping over [] classes is complicated. + +While working on 10.22 I realized that I could simplify yet again by moving +more of the parsing into the pre-pass, thus avoiding doing it in two places, so +after 10.22 was released, the code underwent yet another big refactoring. This +is how it is from 10.23 onwards: + +The function called parse_regex() scans the pattern characters, parsing them +into literal data and meta characters. It converts escapes such as \x{123} +into literals, handles \Q...\E, and skips over comments and non-significant +white space. The result of the scanning is put into a vector of 32-bit unsigned +integers. Values less than 0x80000000 are literal data. Higher values represent +meta-characters. The top 16-bits of such values identify the meta-character, +and these are given names such as META_CAPTURE. The lower 16-bits are available +for data, for example, the capturing group number. The only situation in which +literal data values greater than 0x7fffffff can appear is when the 32-bit +library is running in non-UTF mode. This is handled by having a special +meta-character that is followed by the 32-bit data value. + +The size of the parsed pattern vector, when auto-callouts are not enabled, is +bounded by the length of the pattern (with one exception). The code is written +so that each item in the pattern uses no more vector elements than the number +of code units in the item itself. The exception is the aforementioned large +32-bit number handling. For this reason, 32-bit non-UTF patterns are scanned in +advance to check for such values. When auto-callouts are enabled, the generous +assumption is made that there will be a callout for each pattern code unit +(which of course is only actually true if all code units are literals) plus one +at the end. A default parsed pattern vector is defined on the system stack, to +minimize memory handling, but if this is not big enough, heap memory is used. + +As before, the actual compiling function is run twice, the first time to +determine the amount of memory needed for the final compiled pattern. It +now processes the parsed pattern vector, not the pattern itself, although some +of the parsed items refer to strings in the pattern - for example, group +names. As escapes and comments have already been processed, the code is a bit +simpler than before. + +Most errors can be diagnosed during the parsing scan. For those that cannot +(for example, "lookbehind assertion is not fixed length"), the parsed code +contains offsets into the pattern so that the actual compiling code can +report where errors are. + + +The elements of the parsed pattern vector +----------------------------------------- + +The word "offset" below means a code unit offset into the pattern. When +PCRE2_SIZE (which is usually size_t) is no bigger than uint32_t, an offset is +stored in a single parsed pattern element. Otherwise (typically on 64-bit +systems) it occupies two elements. The following meta items occupy just one +element, with no data: + +META_ACCEPT (*ACCEPT) +META_ASTERISK * +META_ASTERISK_PLUS *+ +META_ASTERISK_QUERY *? +META_ATOMIC (?> start of atomic group +META_CIRCUMFLEX ^ metacharacter +META_CLASS [ start of non-empty class +META_CLASS_EMPTY [] empty class - only with PCRE2_ALLOW_EMPTY_CLASS +META_CLASS_EMPTY_NOT [^] negative empty class - ditto +META_CLASS_END ] end of non-empty class +META_CLASS_NOT [^ start non-empty negative class +META_COMMIT (*COMMIT) - no argument (see below for with argument) +META_COND_ASSERT (?(?assertion) +META_DOLLAR $ metacharacter +META_DOT . metacharacter +META_END End of pattern (this value is 0x80000000) +META_FAIL (*FAIL) +META_KET ) closing parenthesis +META_LOOKAHEAD (?= start of lookahead +META_LOOKAHEAD_NA (*napla: start of non-atomic lookahead +META_LOOKAHEADNOT (?! start of negative lookahead +META_NOCAPTURE (?: no capture parens +META_PLUS + +META_PLUS_PLUS ++ +META_PLUS_QUERY +? +META_PRUNE (*PRUNE) - no argument (see below for with argument) +META_QUERY ? +META_QUERY_PLUS ?+ +META_QUERY_QUERY ?? +META_RANGE_ESCAPED hyphen in class range with at least one escape +META_RANGE_LITERAL hyphen in class range defined literally +META_SKIP (*SKIP) - no argument (see below for with argument) +META_THEN (*THEN) - no argument (see below for with argument) + +The two RANGE values occur only in character classes. They are positioned +between two literals that define the start and end of the range. In an EBCDIC +environment it is necessary to know whether either of the range values was +specified as an escape. In an ASCII/Unicode environment the distinction is not +relevant. + +The following have data in the lower 16 bits, and may be followed by other data +elements: + +META_ALT | alternation +META_BACKREF back reference +META_CAPTURE start of capturing group +META_ESCAPE non-literal escape sequence +META_RECURSE recursion call + +If the data for META_ALT is non-zero, it is inside a lookbehind, and the data +is the maximum length of its branch (see META_LOOKBEHIND below for more +detail). + +META_BACKREF, META_CAPTURE, and META_RECURSE have the capture group number as +their data in the lower 16 bits of the element. META_RECURSE is followed by an +offset, for use in error messages. + +META_BACKREF is followed by an offset if the back reference group number is 10 +or more. The offsets of the first occurrences of references to groups whose +numbers are less than 10 are put in cb->small_ref_offset[] (only the first +occurrence is useful). On 64-bit systems this avoids using more than two parsed +pattern elements for items such as \3. The offset is used when an error occurs +because the reference is to a non-existent group. + +META_ESCAPE has an ESC_xxx value as its data. For ESC_P and ESC_p, the next +element contains the 16-bit type and data property values, packed together. +ESC_g and ESC_k are used only for named references - numerical ones are turned +into META_RECURSE or META_BACKREF as appropriate. ESC_g and ESC_k are followed +by a length and an offset into the pattern to specify the name. + +The following have one data item that follows in the next vector element: + +META_BIGVALUE Next is a literal >= META_END +META_POSIX POSIX class item (data identifies the class) +META_POSIX_NEG negative POSIX class item (ditto) + +The following are followed by a length element, then a number of character code +values (which should match with the length): + +META_MARK (*MARK:xxxx) +META_COMMIT_ARG )*COMMIT:xxxx) +META_PRUNE_ARG (*PRUNE:xxx) +META_SKIP_ARG (*SKIP:xxxx) +META_THEN_ARG (*THEN:xxxx) + +The following are followed by a length element, then an offset in the pattern +that identifies the name: + +META_COND_NAME (?() or (?('name') or (?(name) +META_COND_RNAME (?(R&name) +META_COND_RNUMBER (?(Rdigits) +META_RECURSE_BYNAME (?&name) +META_BACKREF_BYNAME \k'name' + +META_COND_RNUMBER is used for names that start with R and continue with digits, +because this is an ambiguous case. It could be a back reference to a group with +that name, or it could be a recursion test on a numbered group. + +This one is followed by an offset, for use in error messages, then a number: + +META_COND_NUMBER (?([+-]digits) + +The following is followed just by an offset, for use in error messages: + +META_COND_DEFINE (?(DEFINE) + +The following are at first also followed just by an offset for use in error +messages. After the lengths of the branches of a lookbehind group have been +checked the error offset is no longer needed. The lower 16 bits of the main +word are now set to the maximum length of the first branch of the lookbehind +group, and the second word is set to the mimimum matching length for a +variable-length lookbehind group, or to LOOKBEHIND_MAX for a group whose +branches are all of fixed length. These values are used when generating +OP_REVERSE or OP_VREVERSE for the first branch. The miminum value is also used +for any subsequent branches because there is only room for one value (the +branch maximum length) in a META_ALT item. + +META_LOOKBEHIND (?<= start of lookbehind +META_LOOKBEHIND_NA (*naplb: start of non-atomic lookbehind +META_LOOKBEHINDNOT (?' and 1 for '>='; +the next two are the major and minor numbers: + +META_COND_VERSION (?(VERSIONx.y) + +Callouts are converted into one of two items: + +META_CALLOUT_NUMBER (?C with numerical argument +META_CALLOUT_STRING (?C with string argument + +In both cases, the next two elements contain the offset and length of the next +item in the pattern. Then there is either one callout number, or a length and +an offset for the string argument. The length includes both delimiters. + + +Traditional matching function +----------------------------- + +The "traditional", and original, matching function is called pcre2_match(), and +it implements an NFA algorithm, similar to the original Henry Spencer algorithm +and the way that Perl works. This is not surprising, since it is intended to be +as compatible with Perl as possible. This is the function most users of PCRE2 +will use most of the time. If PCRE2 is compiled with just-in-time (JIT) +support, and studying a compiled pattern with JIT is successful, the JIT code +is run instead of the normal pcre2_match() code, but the result is the same. + + +Supplementary matching function +------------------------------- + +There is also a supplementary matching function called pcre2_dfa_match(). This +implements a DFA matching algorithm that searches simultaneously for all +possible matches that start at one point in the subject string. (Going back to +my roots: see Historical Note 1 above.) This function intreprets the same +compiled pattern data as pcre2_match(); however, not all the facilities are +available, and those that are do not always work in quite the same way. See the +user documentation for details. + +The algorithm that is used for pcre2_dfa_match() is not a traditional FSM, +because it may have a number of states active at one time. More work would be +needed at compile time to produce a traditional FSM where only one state is +ever active at once. I believe some other regex matchers work this way. JIT +support is not available for this kind of matching. + + +Changeable options +------------------ + +The /i, /m, or /s options (PCRE2_CASELESS, PCRE2_MULTILINE, PCRE2_DOTALL) and +some others may be changed in the middle of patterns by items such as (?i). +Their processing is handled entirely at compile time by generating different +opcodes for the different settings. The runtime functions do not need to keep +track of an option's state. + +PCRE2_DUPNAMES, PCRE2_EXTENDED, PCRE2_EXTENDED_MORE, and PCRE2_NO_AUTO_CAPTURE +are tracked and processed during the parsing pre-pass. The others are handled +from META_OPTIONS items during the main compile phase. + + +Format of compiled patterns +--------------------------- + +The compiled form of a pattern is a vector of unsigned code units (bytes in +8-bit mode, shorts in 16-bit mode, 32-bit words in 32-bit mode), containing +items of variable length. The first code unit in an item contains an opcode, +and the length of the item is either implicit in the opcode or contained in the +data that follows it. + +In many cases listed below, LINK_SIZE data values are specified for offsets +within the compiled pattern. LINK_SIZE always specifies a number of bytes. The +default value for LINK_SIZE is 2, except for the 32-bit library, where it can +only be 4. The 8-bit library can be compiled to use 3-byte or 4-byte values, +and the 16-bit library can be compiled to use 4-byte values, though this +impairs performance. Specifying a LINK_SIZE larger than 2 for these libraries is +necessary only when patterns whose compiled length is greater than 65535 code +units are going to be processed. When a LINK_SIZE value uses more than one code +unit, the most significant unit is first. + +In this description, we assume the "normal" compilation options. Data values +that are counts (e.g. quantifiers) are always two bytes long in 8-bit mode +(most significant byte first), and one code unit in 16-bit and 32-bit modes. + + +Opcodes with no following data +------------------------------ + +These items are all just one unit long: + + OP_END end of pattern + OP_ANY match any one character other than newline + OP_ALLANY match any one character, including newline + OP_ANYBYTE match any single code unit, even in UTF-8/16 mode + OP_SOD match start of data: \A + OP_SOM, start of match (subject + offset): \G + OP_SET_SOM, set start of match (\K) + OP_CIRC ^ (start of data) + OP_CIRCM ^ multiline mode (start of data or after newline) + OP_NOT_WORD_BOUNDARY \W + OP_WORD_BOUNDARY \w + OP_NOT_DIGIT \D + OP_DIGIT \d + OP_NOT_HSPACE \H + OP_HSPACE \h + OP_NOT_WHITESPACE \S + OP_WHITESPACE \s + OP_NOT_VSPACE \V + OP_VSPACE \v + OP_NOT_WORDCHAR \W + OP_WORDCHAR \w + OP_EODN match end of data or newline at end: \Z + OP_EOD match end of data: \z + OP_DOLL $ (end of data, or before final newline) + OP_DOLLM $ multiline mode (end of data or before newline) + OP_EXTUNI match an extended Unicode grapheme cluster + OP_ANYNL match any Unicode newline sequence + + OP_ASSERT_ACCEPT ) + OP_ACCEPT ) These are Perl 5.10's "backtracking control + OP_COMMIT ) verbs". If OP_ACCEPT is inside capturing + OP_FAIL ) parentheses, it may be preceded by one or more + OP_PRUNE ) OP_CLOSE, each followed by a number that + OP_SKIP ) indicates which parentheses must be closed. + OP_THEN ) + +OP_ASSERT_ACCEPT is used when (*ACCEPT) is encountered within an assertion. +This ends the assertion, not the entire pattern match. The assertion (?!) is +always optimized to OP_FAIL. + +OP_ALLANY is used for '.' when PCRE2_DOTALL is set. It is also used for \C in +non-UTF modes and in UTF-32 mode (since one code unit still equals one +character). Another use is for [^] when empty classes are permitted +(PCRE2_ALLOW_EMPTY_CLASS is set). + + +Backtracking control verbs +-------------------------- + +Verbs with no arguments generate opcodes with no following data (as listed +in the section above). + +(*MARK:NAME) generates OP_MARK followed by the mark name, preceded by a +length in one code unit, and followed by a binary zero. The name length is +limited by the size of the code unit. + +(*ACCEPT:NAME) and (*FAIL:NAME) are compiled as (*MARK:NAME)(*ACCEPT) and +(*MARK:NAME)(*FAIL) respectively. + +For (*COMMIT:NAME), (*PRUNE:NAME), (*SKIP:NAME), and (*THEN:NAME), the opcodes +OP_COMMIT_ARG, OP_PRUNE_ARG, OP_SKIP_ARG, and OP_THEN_ARG are used, with the +name following in the same format as for OP_MARK. + + +Matching literal characters +--------------------------- + +The OP_CHAR opcode is followed by a single character that is to be matched +casefully. For caseless matching of characters that have at most two +case-equivalent code points, OP_CHARI is used. In UTF-8 or UTF-16 modes, the +character may be more than one code unit long. In UTF-32 mode, characters are +always exactly one code unit long. + +If there is only one character in a character class, OP_CHAR or OP_CHARI is +used for a positive class, and OP_NOT or OP_NOTI for a negative one (that is, +for something like [^a]). + +Caseless matching (positive or negative) of characters that have more than two +case-equivalent code points (which is possible only in UTF mode) is handled by +compiling a Unicode property item (see below), with the pseudo-property +PT_CLIST. The value of this property is an offset in a vector called +"ucd_caseless_sets" which identifies the start of a short list of case +equivalent characters, terminated by the value NOTACHAR (0xffffffff). + + +Repeating single characters +--------------------------- + +The common repeats (*, +, ?), when applied to a single character, use the +following opcodes, which come in caseful and caseless versions: + + Caseful Caseless + OP_STAR OP_STARI + OP_MINSTAR OP_MINSTARI + OP_POSSTAR OP_POSSTARI + OP_PLUS OP_PLUSI + OP_MINPLUS OP_MINPLUSI + OP_POSPLUS OP_POSPLUSI + OP_QUERY OP_QUERYI + OP_MINQUERY OP_MINQUERYI + OP_POSQUERY OP_POSQUERYI + +Each opcode is followed by the character that is to be repeated. In ASCII or +UTF-32 modes, these are two-code-unit items; in UTF-8 or UTF-16 modes, the +length is variable. Those with "MIN" in their names are the minimizing +versions. Those with "POS" in their names are possessive versions. Other kinds +of repeat make use of these opcodes: + + Caseful Caseless + OP_UPTO OP_UPTOI + OP_MINUPTO OP_MINUPTOI + OP_POSUPTO OP_POSUPTOI + OP_EXACT OP_EXACTI + +Each of these is followed by a count and then the repeated character. The count +is two bytes long in 8-bit mode (most significant byte first), or one code unit +in 16-bit and 32-bit modes. + +OP_UPTO matches from 0 to the given number. A repeat with a non-zero minimum +and a fixed maximum is coded as an OP_EXACT followed by an OP_UPTO (or +OP_MINUPTO or OPT_POSUPTO). + +Another set of matching repeating opcodes (called OP_NOTSTAR, OP_NOTSTARI, +etc.) are used for repeated, negated, single-character classes such as [^a]*. +The normal single-character opcodes (OP_STAR, etc.) are used for repeated +positive single-character classes. + + +Repeating character types +------------------------- + +Repeats of things like \d are done exactly as for single characters, except +that instead of a character, the opcode for the type (e.g. OP_DIGIT) is stored +in the next code unit. The opcodes are: + + OP_TYPESTAR + OP_TYPEMINSTAR + OP_TYPEPOSSTAR + OP_TYPEPLUS + OP_TYPEMINPLUS + OP_TYPEPOSPLUS + OP_TYPEQUERY + OP_TYPEMINQUERY + OP_TYPEPOSQUERY + OP_TYPEUPTO + OP_TYPEMINUPTO + OP_TYPEPOSUPTO + OP_TYPEEXACT + + +Match by Unicode property +------------------------- + +OP_PROP and OP_NOTPROP are used for positive and negative matches of a +character by testing its Unicode property (the \p and \P escape sequences). +Each is followed by two code units that encode the desired property as a type +and a value. The types are a set of #defines of the form PT_xxx, and the values +are enumerations of the form ucp_xx, defined in the pcre2_ucp.h source file. +The value is relevant only for PT_GC (General Category), PT_PC (Particular +Category), PT_SC (Script), PT_BIDICL (Bidi Class), PT_BOOL (Boolean property), +and the pseudo-property PT_CLIST, which is used to identify a list of +case-equivalent characters when there are three or more (see above). + +Repeats of these items use the OP_TYPESTAR etc. set of opcodes, followed by +three code units: OP_PROP or OP_NOTPROP, and then the desired property type and +value. + + +Character classes +----------------- + +If there is only one character in a class, OP_CHAR or OP_CHARI is used for a +positive class, and OP_NOT or OP_NOTI for a negative one (that is, for +something like [^a]), except when caselessly matching a character that has more +than two case-equivalent code points (which can happen only in UTF mode). In +this case a Unicode property item is used, as described above in "Matching +literal characters". + +A set of repeating opcodes (called OP_NOTSTAR etc.) are used for repeated, +negated, single-character classes. The normal single-character opcodes +(OP_STAR, etc.) are used for repeated positive single-character classes. + +When there is more than one character in a class, and all the code points are +less than 256, OP_CLASS is used for a positive class, and OP_NCLASS for a +negative one. In either case, the opcode is followed by a 32-byte (16-short, +8-word) bit map containing a 1 bit for every character that is acceptable. The +bits are counted from the least significant end of each unit. In caseless mode, +bits for both cases are set. + +The reason for having both OP_CLASS and OP_NCLASS is so that, in UTF-8 and +16-bit and 32-bit modes, subject characters with values greater than 255 can be +handled correctly. For OP_CLASS they do not match, whereas for OP_NCLASS they +do. + +For classes containing characters with values greater than 255 or that contain +\p or \P, OP_XCLASS is used. It optionally uses a bit map if any acceptable +code points are less than 256, followed by a list of pairs (for a range) and/or +single characters and/or properties. In caseless mode, all equivalent +characters are explicitly listed. + +OP_XCLASS is followed by a LINK_SIZE value containing the total length of the +opcode and its data. This is followed by a code unit containing flag bits: +XCL_NOT indicates that this is a negative class, and XCL_MAP indicates that a +bit map is present. There follows the bit map, if XCL_MAP is set, and then a +sequence of items coded as follows: + + XCL_END marks the end of the list + XCL_SINGLE one character follows + XCL_RANGE two characters follow + XCL_PROP a Unicode property (type, value) follows + XCL_NOTPROP a Unicode property (type, value) follows + +If a range starts with a code point less than 256 and ends with one greater +than 255, it is split into two ranges, with characters less than 256 being +indicated in the bit map, and the rest with XCL_RANGE. + +When XCL_NOT is set, the bit map, if present, contains bits for characters that +are allowed (exactly as for OP_NCLASS), but the list of items that follow it +specifies characters and properties that are not allowed. + + +Back references +--------------- + +OP_REF (caseful) or OP_REFI (caseless) is followed by a count containing the +reference number when the reference is to a unique capturing group (either by +number or by name). When named groups are used, there may be more than one +group with the same name. In this case, a reference to such a group by name +generates OP_DNREF or OP_DNREFI. These are followed by two counts: the index +(not the byte offset) in the group name table of the first entry for the +required name, followed by the number of groups with the same name. The +matching code can then search for the first one that is set. + + +Repeating character classes and back references +----------------------------------------------- + +Single-character classes are handled specially (see above). This section +applies to other classes and also to back references. In both cases, the repeat +information follows the base item. The matching code looks at the following +opcode to see if it is one of these: + + OP_CRSTAR + OP_CRMINSTAR + OP_CRPOSSTAR + OP_CRPLUS + OP_CRMINPLUS + OP_CRPOSPLUS + OP_CRQUERY + OP_CRMINQUERY + OP_CRPOSQUERY + OP_CRRANGE + OP_CRMINRANGE + OP_CRPOSRANGE + +All but the last three are single-code-unit items, with no data. The range +opcodes are followed by the minimum and maximum repeat counts. + + +Brackets and alternation +------------------------ + +A pair of non-capturing round brackets is wrapped round each expression at +compile time, so alternation always happens in the context of brackets. + +[Note for North Americans: "bracket" to some English speakers, including +myself, can be round, square, curly, or pointy. Hence this usage rather than +"parentheses".] + +Non-capturing brackets use the opcode OP_BRA, capturing brackets use OP_CBRA. A +bracket opcode is followed by a LINK_SIZE value which gives the offset to the +next alternative OP_ALT or, if there aren't any branches, to the terminating +opcode. Each OP_ALT is followed by a LINK_SIZE value giving the offset to the +next one, or to the final opcode. For capturing brackets, the bracket number is +a count that immediately follows the offset. + +There are several opcodes that mark the end of a subpattern group. OP_KET is +used for subpatterns that do not repeat indefinitely, OP_KETRMIN and +OP_KETRMAX are used for indefinite repetitions, minimally or maximally +respectively, and OP_KETRPOS for possessive repetitions (see below for more +details). All four are followed by a LINK_SIZE value giving (as a positive +number) the offset back to the matching opening bracket opcode. + +If a subpattern is quantified such that it is permitted to match zero times, it +is preceded by one of OP_BRAZERO, OP_BRAMINZERO, or OP_SKIPZERO. These are +single-unit opcodes that tell the matcher that skipping the following +subpattern entirely is a valid match. In the case of the first two, not +skipping the pattern is also valid (greedy and non-greedy). The third is used +when a pattern has the quantifier {0,0}. It cannot be entirely discarded, +because it may be called as a subroutine from elsewhere in the pattern. + +A subpattern with an indefinite maximum repetition is replicated in the +compiled data its minimum number of times (or once with OP_BRAZERO if the +minimum is zero), with the final copy terminating with OP_KETRMIN or OP_KETRMAX +as appropriate. + +A subpattern with a bounded maximum repetition is replicated in a nested +fashion up to the maximum number of times, with OP_BRAZERO or OP_BRAMINZERO +before each replication after the minimum, so that, for example, (abc){2,5} is +compiled as (abc)(abc)((abc)((abc)(abc)?)?)?, except that each bracketed group +has the same number. + +When a repeated subpattern has an unbounded upper limit, it is checked to see +whether it could match an empty string. If this is the case, the opcode in the +final replication is changed to OP_SBRA or OP_SCBRA. This tells the matcher +that it needs to check for matching an empty string when it hits OP_KETRMIN or +OP_KETRMAX, and if so, to break the loop. + + +Possessive brackets +------------------- + +When a repeated group (capturing or non-capturing) is marked as possessive by +the "+" notation, e.g. (abc)++, different opcodes are used. Their names all +have POS on the end, e.g. OP_BRAPOS instead of OP_BRA and OP_SCBRAPOS instead +of OP_SCBRA. The end of such a group is marked by OP_KETRPOS. If the minimum +repetition is zero, the group is preceded by OP_BRAPOSZERO. + + +Once-only (atomic) groups +------------------------- + +These are just like other subpatterns, but they start with the opcode OP_ONCE. +The check for matching an empty string in an unbounded repeat is handled +entirely at runtime, so there is just this one opcode for atomic groups. + + +Assertions +---------- + +Forward assertions are also just like other subpatterns, but starting with one +of the opcodes OP_ASSERT, OP_ASSERT_NA (non-atomic assertion), or +OP_ASSERT_NOT. + +Backward assertions use the opcodes OP_ASSERTBACK, OP_ASSERTBACK_NA, and +OP_ASSERTBACK_NOT. If all the branches of a backward assertion are of fixed +length (not necessarily the same), the first opcode inside each branch is +OP_REVERSE, followed by an IMM2_SIZE count of the number of characters to move +back the pointer in the subject string, thus allowing each branch to have a +different (but fixed) length. + +Variable-length backward assertions whose maximum matching length is limited +are also supported. For such assertions, the first opcode inside each branch is +OP_VREVERSE, followed by the minimum and maximum lengths for that branch, +unless these happen to be equal, in which case OP_REVERSE is used. These +IMM2_SIZE values occupy two code units each in 8-bit mode, and 1 code unit in +16/32 bit modes. + +In ASCII or UTF-32 mode, the character counts in OP_REVERSE and OP_VREVERSE are +also the number of code units, but in UTF-8/16 mode each character may occupy +more than one code unit. + + +Conditional subpatterns +----------------------- + +These are like other subpatterns, but they start with the opcode OP_COND, or +OP_SCOND for one that might match an empty string in an unbounded repeat. + +If the condition is a back reference, this is stored at the start of the +subpattern using the opcode OP_CREF followed by a count containing the +reference number, provided that the reference is to a unique capturing group. +If the reference was by name and there is more than one group with that name, +OP_DNCREF is used instead. It is followed by two counts: the index in the group +names table, and the number of groups with the same name. The allows the +matcher to check if any group with the given name is set. + +If the condition is "in recursion" (coded as "(?(R)"), or "in recursion of +group x" (coded as "(?(Rx)"), the group number is stored at the start of the +subpattern using the opcode OP_RREF (with a value of RREF_ANY (0xffff) for "the +whole pattern") or OP_DNRREF (with data as for OP_DNCREF). + +For a DEFINE condition, OP_FALSE is used (with no associated data). During +compilation, however, a DEFINE condition is coded as OP_DEFINE so that, when +the conditional group is complete, there can be a check to ensure that it +contains only one top-level branch. Once this has happened, the opcode is +changed to OP_FALSE, so the matcher never sees OP_DEFINE. + +There is a special PCRE2-specific condition of the form (VERSION[>]=x.y), which +tests the PCRE2 version number. This compiles into one of the opcodes OP_TRUE +or OP_FALSE. + +If a condition is not a back reference, recursion test, DEFINE, or VERSION, it +must start with a parenthesized atomic assertion, whose opcode normally +immediately follows OP_COND or OP_SCOND. However, if automatic callouts are +enabled, a callout is inserted immediately before the assertion. It is also +possible to insert a manual callout at this point. Only assertion conditions +may have callouts preceding the condition. + +A condition that is the negative assertion (?!) is optimized to OP_FAIL in all +parts of the pattern, so this is another opcode that may appear as a condition. +It is treated the same as OP_FALSE. + + +Recursion +--------- + +Recursion either matches the current pattern, or some subexpression. The opcode +OP_RECURSE is followed by a LINK_SIZE value that is the offset to the starting +bracket from the start of the whole pattern. OP_RECURSE is also used for +"subroutine" calls, even though they are not strictly a recursion. Up till +release 10.30 recursions were treated as atomic groups, making them +incompatible with Perl (but PCRE had them well before Perl did). From 10.30, +backtracking into recursions is supported. + +Repeated recursions used to be wrapped inside OP_ONCE brackets, which not only +forced no backtracking, but also allowed repetition to be handled as for other +bracketed groups. From 10.30 onwards, repeated recursions are duplicated for +their minimum repetitions, and then wrapped in non-capturing brackets for the +remainder. For example, (?1){3} is treated as (?1)(?1)(?1), and (?1){2,4} is +treated as (?1)(?1)(?:(?1)){0,2}. + + +Callouts +-------- + +A callout may have either a numerical argument or a string argument. These use +OP_CALLOUT or OP_CALLOUT_STR, respectively. In each case these are followed by +two LINK_SIZE values giving the offset in the pattern string to the start of +the following item, and another count giving the length of this item. These +values make it possible for pcre2test to output useful tracing information +using callouts. + +In the case of a numeric callout, after these two values there is a single code +unit containing the callout number, in the range 0-255, with 255 being used for +callouts that are automatically inserted as a result of the PCRE2_AUTO_CALLOUT +option. Thus, this opcode item is of fixed length: + + [OP_CALLOUT] [PATTERN_OFFSET] [PATTERN_LENGTH] [NUMBER] + +For callouts with string arguments, OP_CALLOUT_STR has three more data items: +a LINK_SIZE value giving the complete length of the entire opcode item, a +LINK_SIZE item containing the offset within the pattern string to the start of +the string argument, and the string itself, preceded by its starting delimiter +and followed by a binary zero. When a callout function is called, a pointer to +the actual string is passed, but the delimiter can be accessed as string[-1] if +the application needs it. In the 8-bit library, the callout in /X(?C'abc')Y/ is +compiled as the following bytes (decimal numbers represent binary values): + + [OP_CALLOUT_STR] [0] [10] [0] [1] [0] [14] [0] [5] ['] [a] [b] [c] [0] + -------- ------- -------- ------- + | | | | + ------- LINK_SIZE items ------ + +Opcode table checking +--------------------- + +The last opcode that is defined in pcre2_internal.h is OP_TABLE_LENGTH. This is +not a real opcode, but is used to check at compile time that tables indexed by +opcode are the correct length, in order to catch updating errors. + +Philip Hazel +November 2023 diff --git a/INSTALL b/INSTALL new file mode 100644 index 0000000..e82fd21 --- /dev/null +++ b/INSTALL @@ -0,0 +1,368 @@ +Installation Instructions +************************* + + Copyright (C) 1994-1996, 1999-2002, 2004-2017, 2020-2021 Free +Software Foundation, Inc. + + Copying and distribution of this file, with or without modification, +are permitted in any medium without royalty provided the copyright +notice and this notice are preserved. This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell command './configure && make && make install' +should configure, build, and install this package. The following +more-detailed instructions are generic; see the 'README' file for +instructions specific to this package. Some packages provide this +'INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The 'configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a 'Makefile' in each directory of the package. +It may also create one or more '.h' files containing system-dependent +definitions. Finally, it creates a shell script 'config.status' that +you can run in the future to recreate the current configuration, and a +file 'config.log' containing compiler output (useful mainly for +debugging 'configure'). + + It can also use an optional file (typically called 'config.cache' and +enabled with '--cache-file=config.cache' or simply '-C') that saves the +results of its tests to speed up reconfiguring. Caching is disabled by +default to prevent problems with accidental use of stale cache files. + + If you need to do unusual things to compile the package, please try +to figure out how 'configure' could check whether to do them, and mail +diffs or instructions to the address given in the 'README' so they can +be considered for the next release. If you are using the cache, and at +some point 'config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file 'configure.ac' (or 'configure.in') is used to create +'configure' by a program called 'autoconf'. You need 'configure.ac' if +you want to change it or regenerate 'configure' using a newer version of +'autoconf'. + + The simplest way to compile this package is: + + 1. 'cd' to the directory containing the package's source code and type + './configure' to configure the package for your system. + + Running 'configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type 'make' to compile the package. + + 3. Optionally, type 'make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type 'make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the 'make install' phase executed with root + privileges. + + 5. Optionally, type 'make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior 'make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing 'make clean'. To also remove the + files that 'configure' created (so you can compile the package for + a different kind of computer), type 'make distclean'. There is + also a 'make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type 'make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide 'make + distcheck', which can by used by developers to test that all other + targets like 'make install' and 'make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the 'configure' script does not know about. Run './configure --help' +for details on some of the pertinent environment variables. + + You can give 'configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here is +an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU 'make'. 'cd' to the +directory where you want the object files and executables to go and run +the 'configure' script. 'configure' automatically checks for the source +code in the directory that 'configure' is in and in '..'. This is known +as a "VPATH" build. + + With a non-GNU 'make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use 'make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple '-arch' options to the +compiler but only a single '-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the 'lipo' tool if you have problems. + +Installation Names +================== + + By default, 'make install' installs the package's commands under +'/usr/local/bin', include files under '/usr/local/include', etc. You +can specify an installation prefix other than '/usr/local' by giving +'configure' the option '--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option '--exec-prefix=PREFIX' to 'configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like '--bindir=DIR' to specify different values for particular +kinds of files. Run 'configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the default +for these options is expressed in terms of '${prefix}', so that +specifying just '--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to 'configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +'make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, 'make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +'${prefix}'. Any directories that were specified during 'configure', +but not in terms of '${prefix}', must each be overridden at install time +for the entire installation to be relocated. The approach of makefile +variable overrides for each directory variable is required by the GNU +Coding Standards, and ideally causes no recompilation. However, some +platforms have known limitations with the semantics of shared libraries +that end up requiring recompilation when using this method, particularly +noticeable in packages that use GNU Libtool. + + The second method involves providing the 'DESTDIR' variable. For +example, 'make install DESTDIR=/alternate/directory' will prepend +'/alternate/directory' before all installation names. The approach of +'DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of '${prefix}' +at 'configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving 'configure' the +option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. + + Some packages pay attention to '--enable-FEATURE' options to +'configure', where FEATURE indicates an optional part of the package. +They may also pay attention to '--with-PACKAGE' options, where PACKAGE +is something like 'gnu-as' or 'x' (for the X Window System). The +'README' should mention any '--enable-' and '--with-' options that the +package recognizes. + + For packages that use the X Window System, 'configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the 'configure' options '--x-includes=DIR' and +'--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of 'make' will be. For these packages, running './configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with 'make V=1'; while running './configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with 'make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC +is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX 'make' updates targets which have the same timestamps as their +prerequisites, which makes it generally unusable when shipped generated +files such as 'configure' are involved. Use GNU 'make' instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its '' header file. The option '-nodtk' can be used as a +workaround. If GNU CC is not installed, it is therefore recommended to +try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put '/usr/ucb' early in your 'PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in '/usr/bin'. So, if you need '/usr/ucb' +in your 'PATH', put it _after_ '/usr/bin'. + + On Haiku, software installed for all users goes in '/boot/common', +not '/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features 'configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, 'configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +'--build=TYPE' option. TYPE can either be a short name for the system +type, such as 'sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file 'config.sub' for the possible values of each field. If +'config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option '--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with '--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for 'configure' scripts to share, +you can create a site shell script called 'config.site' that gives +default values for variables like 'CC', 'cache_file', and 'prefix'. +'configure' looks for 'PREFIX/share/config.site' if it exists, then +'PREFIX/etc/config.site' if it exists. Or, you can set the +'CONFIG_SITE' environment variable to the location of the site script. +A warning: not all 'configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to 'configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the 'configure' command line, using 'VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified 'gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an +Autoconf limitation. Until the limitation is lifted, you can use this +workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +'configure' Invocation +====================== + + 'configure' recognizes the following options to control how it +operates. + +'--help' +'-h' + Print a summary of all of the options to 'configure', and exit. + +'--help=short' +'--help=recursive' + Print a summary of the options unique to this package's + 'configure', and exit. The 'short' variant lists options used only + in the top level, while the 'recursive' variant lists options also + present in any nested packages. + +'--version' +'-V' + Print the version of Autoconf used to generate the 'configure' + script, and exit. + +'--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally 'config.cache'. FILE defaults to '/dev/null' to + disable caching. + +'--config-cache' +'-C' + Alias for '--cache-file=config.cache'. + +'--quiet' +'--silent' +'-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to '/dev/null' (any error + messages will still be shown). + +'--srcdir=DIR' + Look for the package's source code in directory DIR.

There is one new function, to set +a maximum size for a compiled pattern. The maximum name length for groups is +increased to 128. Some auxiliary files for building under VMS are added. + + +Version 10.43 16-February-2024 +------------------------------ + +There are quite a lot of changes in this release (see ChangeLog and git log for +a list). Those that are not bugfixes or code tidies are: + +* The JIT code no longer supports ARMv5 architecture. + +* A new function pcre2_get_match_data_heapframes_size() for finer heap control. + +* New option flags to restrict the interaction between ASCII and non-ASCII + characters for caseless matching and \d and friends. There are also new + pattern constructs to control these flags from within a pattern. + +* Upgrade to Unicode 15.0.0. + +* Treat a NULL pattern with zero length as an empty string. + +* Added support for limited-length variable-length lookbehind assertions, with + a default maximum length of 255 characters (same as Perl) but with a function + to adjust the limit. + +* Support for LoongArch in JIT. + +* Perl changed the meaning of (for example) {,3} which did not used to be + recognized as a quantifier. Now it means {0,3} and PCRE2 has also changed. + Note that {,} is still not a quantifier. + +* Following Perl, allow spaces and tabs after { and before } in all Perl- + compatible items that use braces, and also around commas in quantifiers. The + one exception in PCRE2 is \u{...}, which is from ECMAScript, not Perl, and + PCRE2 follows ECMAScript usage. + +* Changed the meaning of \w and its synonyms and derivatives (\b and \B) in UCP + mode to follow Perl. It now matches characters whose general categories are L + or N or whose particular categories are Mn (non-spacing mark) or Pc + (combining punctuation). + +* Changed the default meaning of [:xdigit:] in UCP mode to follow Perl. It now + matches the "fullwidth" versions of hex digits. PCRE2_EXTRA_ASCII_DIGIT can + be used to keep it ASCII only. + +* Make PCRE2_UCP the default in UTF mode in pcre2grep and add -no_ucp, + --case-restrict and --posix-digit. + +* Add --group-separator and --no-group-separator to pcre2grep. + + +Version 10.42 11-December-2022 +------------------------------ + +This is an unexpectedly early release to fix a problem that was introduced in +10.41. ChangeLog number 19 (GitHub #139) added the default definition of +PCRE2_CALL_CONVENTION to pcre2posix.c instead of pcre2posix.h, which meant that +programs including pcre2posix.h but not pcre2.h couldn't compile. A new test +that checks this case has been added. + +A couple of other minor issues are also fixed, and a patch for an intermittent +JIT fault is also included. See ChangeLog and the Git log. + + +Version 10.41 06-December-2022 +------------------------------ + +This is another mainly bug-fixing and code-tidying release. There is one +significant upgrade to pcre2grep: it now behaves like GNU grep when matching +more than one pattern and a later pattern matches at an earlier point in the +subject when the matched substrings are being identified by colour or by +offsets. + + +Version 10.40 15-April-2022 +--------------------------- + +This is mostly a bug-fixing and code-tidying release. However, there are some +extensions to Unicode property handling: + +* Added support for Bidi_Class and a number of binary Unicode properties, +including Bidi_Control. + +* A number of changes to script matching for \p and \P: + + (a) Script extensions for a character are now coded as a bitmap instead of + a list of script numbers, which should be faster and does not need a + loop. + + (b) Added the syntax \p{script:xxx} and \p{script_extensions:xxx} (synonyms + sc and scx). + + (c) Changed \p{scriptname} from being the same as \p{sc:scriptname} to being + the same as \p{scx:scriptname} because this change happened in Perl at + release 5.26. + + (d) The standard Unicode 4-letter abbreviations for script names are now + recognized. + + (e) In accordance with Unicode and Perl's "loose matching" rules, spaces, + hyphens, and underscores are ignored in property names, which are then + matched independent of case. + +As always, see ChangeLog for a list of all changes (also the Git log). + + +Version 10.39 29-October-2021 +----------------------------- + +This release is happening soon after 10.38 because the bug fix is important. + +1. Fix incorrect detection of alternatives in first character search in JIT. + +2. Update to Unicode 14.0.0. + +3. Some code cleanups (see ChangeLog). + + +Version 10.38 01-October-2021 +----------------------------- + +As well as some bug fixes and tidies (as always, see ChangeLog for details), +the documentation is updated to list the new URLs, following the move of the +source repository to GitHub and the mailing list to Google Groups. + +* The CMake build system can now build both static and shared libraries in one +go. + +* Following Perl's lead, \K is now locked out in lookaround assertions by +default, but an option is provided to re-enable the previous behaviour. + + +Version 10.37 26-May-2021 +------------------------- + +A few more bug fixes and tidies. The only change of real note is the removal of +the actual POSIX names regcomp etc. from the POSIX wrapper library because +these have caused issues for some applications (see 10.33 #2 below). + + +Version 10.36 04-December-2020 +------------------------------ + +Again, mainly bug fixes and tidies. The only enhancements are the addition of +GNU grep's -m (aka --max-count) option to pcre2grep, and also unifying the +handling of substitution strings for both -O and callouts in pcre2grep, with +the addition of $x{...} and $o{...} to allow for characters whose code points +are greater than 255 in Unicode mode. + +NOTE: there is an outstanding issue with JIT support for MacOS on arm64 +hardware. For details, please see Bugzilla issue #2618. + + +Version 10.35 15-April-2020 +--------------------------- + +Bugfixes, tidies, and a few new enhancements. + +1. Capturing groups that contain recursive backreferences to themselves are no +longer automatically atomic, because the restriction is no longer necessary +as a result of the 10.30 restructuring. + +2. Several new options for pcre2_substitute(). + +3. When Unicode is supported and PCRE2_UCP is set without PCRE2_UTF, Unicode +character properties are used for upper/lower case computations on characters +whose code points are greater than 127. + +4. The character tables (for low-valued characters) can now more easily be +saved and restored in binary. + +5. Updated to Unicode 13.0.0. + + +Version 10.34 21-November-2019 +------------------------------ + +Another release with a few enhancements as well as bugfixes and tidies. The +main new features are: + +1. There is now some support for matching in invalid UTF strings. + +2. Non-atomic positive lookarounds are implemented in the pcre2_match() +interpreter, but not in JIT. + +3. Added two new functions: pcre2_get_match_data_size() and +pcre2_maketables_free(). + +4. Upgraded to Unicode 12.1.0. + + +Version 10.33 16-April-2019 +--------------------------- + +Yet more bugfixes, tidies, and a few enhancements, summarized here (see +ChangeLog for the full list): + +1. Callouts from pcre2_substitute() are now available. + +2. The POSIX functions are now all called pcre2_regcomp() etc., with wrapper +functions that use the standard POSIX names. However, in pcre2posix.h the POSIX +names are defined as macros. This should help avoid linking with the wrong +library in some environments, while still exporting the POSIX names for +pre-existing programs that use them. + +3. Some new options: + + (a) PCRE2_EXTRA_ESCAPED_CR_IS_LF makes \r behave as \n. + + (b) PCRE2_EXTRA_ALT_BSUX enables support for ECMAScript 6's \u{hh...} + construct. + + (c) PCRE2_COPY_MATCHED_SUBJECT causes a copy of a matched subject to be + made, instead of just remembering a pointer. + +4. Some new Perl features: + + (a) Perl 5.28's experimental alphabetic names for atomic groups and + lookaround assertions, for example, (*pla:...) and (*atomic:...). + + (b) The new Perl "script run" features (*script_run:...) and + (*atomic_script_run:...) aka (*sr:...) and (*asr:...). + + (c) When PCRE2_UTF is set, allow non-ASCII letters and decimal digits in + capture group names. + +5. --disable-percent-zt disables the use of %zu and %td in formatting strings +in pcre2test. They were already automatically disabled for VC and older C +compilers. + +6. Some changes related to callouts in pcre2grep: + + (a) Support for running an external program under VMS has been added, in + addition to Windows and fork() support. + + (b) --disable-pcre2grep-callout-fork restricts the callout support in + to the inbuilt echo facility. + + +Version 10.32 10-September-2018 +------------------------------- + +This is another mainly bugfix and tidying release with a few minor +enhancements. These are the main ones: + +1. pcre2grep now supports the inclusion of binary zeros in patterns that are +read from files via the -f option. + +2. ./configure now supports --enable-jit=auto, which automatically enables JIT +if the hardware supports it. + +3. In pcre2_dfa_match(), internal recursive calls no longer use the stack for +local workspace and local ovectors. Instead, an initial block of stack is +reserved, but if this is insufficient, heap memory is used. The heap limit +parameter now applies to pcre2_dfa_match(). + +4. Updated to Unicode version 11.0.0. + +5. (*ACCEPT:ARG), (*FAIL:ARG), and (*COMMIT:ARG) are now supported. + +6. Added support for \N{U+dddd}, but only in Unicode mode. + +7. Added support for (?^) to unset all imnsx options. + + +Version 10.31 12-February-2018 +------------------------------ + +This is mainly a bugfix and tidying release (see ChangeLog for full details). +However, there are some minor enhancements. + +1. New pcre2_config() options: PCRE2_CONFIG_NEVER_BACKSLASH_C and +PCRE2_CONFIG_COMPILED_WIDTHS. + +2. New pcre2_pattern_info() option PCRE2_INFO_EXTRAOPTIONS to retrieve the +extra compile time options. + +3. There are now public names for all the pcre2_compile() error numbers. + +4. Added PCRE2_CALLOUT_STARTMATCH and PCRE2_CALLOUT_BACKTRACK bits to a new +field callout_flags in callout blocks. + + +Version 10.30 14-August-2017 +---------------------------- + +The full list of changes that includes bugfixes and tidies is, as always, in +ChangeLog. These are the most important new features: + +1. The main interpreter, pcre2_match(), has been refactored into a new version +that does not use recursive function calls (and therefore the system stack) for +remembering backtracking positions. This makes --disable-stack-for-recursion a +NOOP. The new implementation allows backtracking into recursive group calls in +patterns, making it more compatible with Perl, and also fixes some other +previously hard-to-do issues. For patterns that have a lot of backtracking, the +heap is now used, and there is an explicit limit on the amount, settable by +pcre2_set_heap_limit() or (*LIMIT_HEAP=xxx). The "recursion limit" is retained, +but is renamed as "depth limit" (though the old names remain for +compatibility). + +There is also a change in the way callouts from pcre2_match() are handled. The +offset_vector field in the callout block is no longer a pointer to the +actual ovector that was passed to the matching function in the match data +block. Instead it points to an internal ovector of a size large enough to hold +all possible captured substrings in the pattern. + +2. The new option PCRE2_ENDANCHORED insists that a pattern match must end at +the end of the subject. + +3. The new option PCRE2_EXTENDED_MORE implements Perl's /xx feature, and +pcre2test is upgraded to support it. Setting within the pattern by (?xx) is +also supported. + +4. (?n) can be used to set PCRE2_NO_AUTO_CAPTURE, because Perl now has this. + +5. Additional compile options in the compile context are now available, and the +first two are: PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES and +PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL. + +6. The newline type PCRE2_NEWLINE_NUL is now available. + +7. The match limit value now also applies to pcre2_dfa_match() as there are +patterns that can use up a lot of resources without necessarily recursing very +deeply. + +8. The option REG_PEND (a GNU extension) is now available for the POSIX +wrapper. Also there is a new option PCRE2_LITERAL which is used to support +REG_NOSPEC. + +9. PCRE2_EXTRA_MATCH_LINE and PCRE2_EXTRA_MATCH_WORD are implemented for the +benefit of pcre2grep, and pcre2grep's -F, -w, and -x options are re-implemented +using PCRE2_LITERAL, PCRE2_EXTRA_MATCH_WORD, and PCRE2_EXTRA_MATCH_LINE. This +is tidier and also fixes some bugs. + +10. The Unicode tables are upgraded from Unicode 8.0.0 to Unicode 10.0.0. + +11. There are some experimental functions for converting foreign patterns +(globs and POSIX patterns) into PCRE2 patterns. + + +Version 10.23 14-February-2017 +------------------------------ + +1. ChangeLog has the details of a lot of bug fixes and tidies. + +2. There has been a major re-factoring of the pcre2_compile.c file. Most syntax +checking is now done in the pre-pass that identifies capturing groups. This has +reduced the amount of duplication and made the code tidier. While doing this, +some minor bugs and Perl incompatibilities were fixed (see ChangeLog for +details.) + +3. Back references are now permitted in lookbehind assertions when there are +no duplicated group numbers (that is, (?| has not been used), and, if the +reference is by name, there is only one group of that name. The referenced +group must, of course be of fixed length. + +4. \g{+} (e.g. \g{+2} ) is now supported. It is a "forward back +reference" and can be useful in repetitions (compare \g{-} ). Perl does +not recognize this syntax. + +5. pcre2grep now automatically expands its buffer up to a maximum set by +--max-buffer-size. + +6. The -t option (grand total) has been added to pcre2grep. + +7. A new function called pcre2_code_copy_with_tables() exists to copy a +compiled pattern along with a private copy of the character tables that is +uses. + +8. A user supplied a number of patches to upgrade pcre2grep under Windows and +tidy the code. + +9. Several updates have been made to pcre2test and test scripts (see +ChangeLog). + + +Version 10.22 29-July-2016 +-------------------------- + +1. ChangeLog has the details of a number of bug fixes. + +2. The POSIX wrapper function regcomp() did not used to support back references +and subroutine calls if called with the REG_NOSUB option. It now does. + +3. A new function, pcre2_code_copy(), is added, to make a copy of a compiled +pattern. + +4. Support for string callouts is added to pcre2grep. + +5. Added the PCRE2_NO_JIT option to pcre2_match(). + +6. The pcre2_get_error_message() function now returns with a negative error +code if the error number it is given is unknown. + +7. Several updates have been made to pcre2test and test scripts (see +ChangeLog). + + +Version 10.21 12-January-2016 +----------------------------- + +1. Many bugs have been fixed. A large number of them were provoked only by very +strange pattern input, and were discovered by fuzzers. Some others were +discovered by code auditing. See ChangeLog for details. + +2. The Unicode tables have been updated to Unicode version 8.0.0. + +3. For Perl compatibility in EBCDIC environments, ranges such as a-z in a +class, where both values are literal letters in the same case, omit the +non-letter EBCDIC code points within the range. + +4. There have been a number of enhancements to the pcre2_substitute() function, +giving more flexibility to replacement facilities. It is now also possible to +cause the function to return the needed buffer size if the one given is too +small. + +5. The PCRE2_ALT_VERBNAMES option causes the "name" parts of special verbs such +as (*THEN:name) to be processed for backslashes and to take note of +PCRE2_EXTENDED. + +6. PCRE2_INFO_HASBACKSLASHC makes it possible for a client to find out if a +pattern uses \C, and --never-backslash-C makes it possible to compile a version +PCRE2 in which the use of \C is always forbidden. + +7. A limit to the length of pattern that can be handled can now be set by +calling pcre2_set_max_pattern_length(). + +8. When matching an unanchored pattern, a match can be required to begin within +a given number of code units after the start of the subject by calling +pcre2_set_offset_limit(). + +9. The pcre2test program has been extended to test new facilities, and it can +now run the tests when LF on its own is not a valid newline sequence. + +10. The RunTest script has also been updated to enable more tests to be run. + +11. There have been some minor performance enhancements. + + +Version 10.20 30-June-2015 +-------------------------- + +1. Callouts with string arguments and the pcre2_callout_enumerate() function +have been implemented. + +2. The PCRE2_NEVER_BACKSLASH_C option, which locks out the use of \C, is added. + +3. The PCRE2_ALT_CIRCUMFLEX option lets ^ match after a newline at the end of a +subject in multiline mode. + +4. The way named subpatterns are handled has been refactored. The previous +approach had several bugs. + +5. The handling of \c in EBCDIC environments has been changed to conform to the +perlebcdic document. This is an incompatible change. + +6. Bugs have been mended, many of them discovered by fuzzers. + + +Version 10.10 06-March-2015 +--------------------------- + +1. Serialization and de-serialization functions have been added to the API, +making it possible to save and restore sets of compiled patterns, though +restoration must be done in the same environment that was used for compilation. + +2. The (*NO_JIT) feature has been added; this makes it possible for a pattern +creator to specify that JIT is not to be used. + +3. A number of bugs have been fixed. In particular, bugs that caused building +on Windows using CMake to fail have been mended. + + +Version 10.00 05-January-2015 +----------------------------- + +Version 10.00 is the first release of PCRE2, a revised API for the PCRE +library. Changes prior to 10.00 are logged in the ChangeLog file for the old +API, up to item 20 for release 8.36. New programs are recommended to use the +new library. Programs that use the original (PCRE1) API will need changing +before linking with the new library. + +**** diff --git a/NON-AUTOTOOLS-BUILD b/NON-AUTOTOOLS-BUILD new file mode 100644 index 0000000..851976a --- /dev/null +++ b/NON-AUTOTOOLS-BUILD @@ -0,0 +1,430 @@ +Building PCRE2 without using autotools +-------------------------------------- + +This document contains the following sections: + + General + Generic instructions for the PCRE2 C libraries + Stack size in Windows environments + Linking programs in Windows environments + Calling conventions in Windows environments + Comments about Win32 builds + Building PCRE2 on Windows with CMake + Building PCRE2 on Windows with Visual Studio + Testing with RunTest.bat + Building PCRE2 on native z/OS and z/VM + Building PCRE2 under VMS + + +GENERAL + +The source of the PCRE2 libraries consists entirely of code written in Standard +C, and so should compile successfully on any system that has a Standard C +compiler and library. + +The PCRE2 distribution includes a "configure" file for use by the +configure/make (autotools) build system, as found in many Unix-like +environments. The README file contains information about the options for +"configure". + +There is also support for CMake, which some users prefer, especially in Windows +environments, though it can also be run in Unix-like environments. See the +section entitled "Building PCRE2 on Windows with CMake" below. + +Versions of src/config.h and src/pcre2.h are distributed in the PCRE2 tarballs +under the names src/config.h.generic and src/pcre2.h.generic. These are +provided for those who build PCRE2 without using "configure" or CMake. If you +use "configure" or CMake, the .generic versions are not used. + + +GENERIC INSTRUCTIONS FOR THE PCRE2 C LIBRARIES + +There are three possible PCRE2 libraries, each handling data with a specific +code unit width: 8, 16, or 32 bits. You can build any combination of them. The +following are generic instructions for building a PCRE2 C library "by hand". If +you are going to use CMake, this section does not apply to you; you can skip +ahead to the CMake section. Note that the settings concerned with 8-bit, +16-bit, and 32-bit code units relate to the type of data string that PCRE2 +processes. They are NOT referring to the underlying operating system bit width. +You do not have to do anything special to compile in a 64-bit environment, for +example. + + (1) Copy or rename the file src/config.h.generic as src/config.h, and edit the + macro settings that it contains to whatever is appropriate for your + environment. In particular, you can alter the definition of the NEWLINE + macro to specify what character(s) you want to be interpreted as line + terminators by default. You need to #define at least one of + SUPPORT_PCRE2_8, SUPPORT_PCRE2_16, or SUPPORT_PCRE2_32, depending on which + libraries you are going to build. You must set all that apply. + + When you subsequently compile any of the PCRE2 modules, you must specify + -DHAVE_CONFIG_H to your compiler so that src/config.h is included in the + sources. + + An alternative approach is not to edit src/config.h, but to use -D on the + compiler command line to make any changes that you need to the + configuration options. In this case -DHAVE_CONFIG_H must not be set. + + NOTE: There have been occasions when the way in which certain parameters + in src/config.h are used has changed between releases. (In the + configure/make world, this is handled automatically.) When upgrading to a + new release, you are strongly advised to review src/config.h.generic + before re-using what you had previously. + + Note also that the src/config.h.generic file is created from a config.h + that was generated by Autotools, which automatically includes settings of + a number of macros that are not actually used by PCRE2 (for example, + HAVE_DLFCN_H). + + (2) Copy or rename the file src/pcre2.h.generic as src/pcre2.h. + + (3) EITHER: + Copy or rename file src/pcre2_chartables.c.dist as + src/pcre2_chartables.c. + + OR: + Compile src/pcre2_dftables.c as a stand-alone program (using + -DHAVE_CONFIG_H if you have set up src/config.h), and then run it with + the single argument "src/pcre2_chartables.c". This generates a set of + standard character tables and writes them to that file. The tables are + generated using the default C locale for your system. If you want to use + a locale that is specified by LC_xxx environment variables, add the -L + option to the pcre2_dftables command. You must use this method if you + are building on a system that uses EBCDIC code. + + The tables in src/pcre2_chartables.c are defaults. The caller of PCRE2 can + specify alternative tables at run time. + + (4) For a library that supports 8-bit code units in the character strings that + it processes, compile the following source files from the src directory, + setting -DPCRE2_CODE_UNIT_WIDTH=8 as a compiler option. Also set + -DHAVE_CONFIG_H if you have set up src/config.h with your configuration, + or else use other -D settings to change the configuration as required. + + pcre2_auto_possess.c + pcre2_chkdint.c + pcre2_chartables.c + pcre2_compile.c + pcre2_config.c + pcre2_context.c + pcre2_convert.c + pcre2_dfa_match.c + pcre2_error.c + pcre2_extuni.c + pcre2_find_bracket.c + pcre2_jit_compile.c + pcre2_maketables.c + pcre2_match.c + pcre2_match_data.c + pcre2_newline.c + pcre2_ord2utf.c + pcre2_pattern_info.c + pcre2_script_run.c + pcre2_serialize.c + pcre2_string_utils.c + pcre2_study.c + pcre2_substitute.c + pcre2_substring.c + pcre2_tables.c + pcre2_ucd.c + pcre2_valid_utf.c + pcre2_xclass.c + + Make sure that you include -I. in the compiler command (or equivalent for + an unusual compiler) so that all included PCRE2 header files are first + sought in the src directory under the current directory. Otherwise you run + the risk of picking up a previously-installed file from somewhere else. + + Note that you must compile pcre2_jit_compile.c, even if you have not + defined SUPPORT_JIT in src/config.h, because when JIT support is not + configured, dummy functions are compiled. When JIT support IS configured, + pcre2_jit_compile.c #includes other files from the sljit subdirectory, + all of whose names begin with "sljit". It also #includes + src/pcre2_jit_match.c and src/pcre2_jit_misc.c, so you should not compile + those yourself. + + Note also that the pcre2_fuzzsupport.c file contains special code that is + useful to those who want to run fuzzing tests on the PCRE2 library. Unless + you are doing that, you can ignore it. + + (5) Now link all the compiled code into an object library in whichever form + your system keeps such libraries. This is the PCRE2 C 8-bit library, + typically called something like libpcre2-8. If your system has static and + shared libraries, you may have to do this once for each type. + + (6) If you want to build a library that supports 16-bit or 32-bit code units, + set 16 or 32 as the value of -DPCRE2_CODE_UNIT_WIDTH when obeying step 4 + above. If you want to build more than one PCRE2 library, repeat steps 4 + and 5 as necessary. + + (7) If you want to build the POSIX wrapper functions (which apply only to the + 8-bit library), ensure that you have the src/pcre2posix.h file and then + compile src/pcre2posix.c. Link the result (on its own) as the pcre2posix + library. If targeting a DLL in Windows, make sure to include + -DPCRE2POSIX_SHARED with your compiler flags. + + (8) The pcre2test program can be linked with any combination of the 8-bit, + 16-bit and 32-bit libraries (depending on what you specfied in + src/config.h) . Compile src/pcre2test.c; don't forget -DHAVE_CONFIG_H if + necessary, but do NOT define PCRE2_CODE_UNIT_WIDTH. Then link with the + appropriate library/ies. If you compiled an 8-bit library, pcre2test also + needs the pcre2posix wrapper library. + + (9) Run pcre2test on the testinput files in the testdata directory, and check + that the output matches the corresponding testoutput files. There are + comments about what each test does in the section entitled "Testing PCRE2" + in the README file. If you compiled more than one of the 8-bit, 16-bit and + 32-bit libraries, you need to run pcre2test with the -16 option to do + 16-bit tests and with the -32 option to do 32-bit tests. + + Some tests are relevant only when certain build-time options are selected. + For example, test 4 is for Unicode support, and will not run if you have + built PCRE2 without it. See the comments at the start of each testinput + file. If you have a suitable Unix-like shell, the RunTest script will run + the appropriate tests for you. The command "RunTest list" will output a + list of all the tests. + + Note that the supplied files are in Unix format, with just LF characters + as line terminators. You may need to edit them to change this if your + system uses a different convention. + +(10) If you have built PCRE2 with SUPPORT_JIT, the JIT features can be tested + by running pcre2test with the -jit option. This is done automatically by + the RunTest script. You might also like to build and run the freestanding + JIT test program, src/pcre2_jit_test.c. + +(11) The pcre2test program tests the POSIX wrapper library, but there is also a + freestanding test program in src/pcre2posix_test.c. It must be linked with + both the pcre2posix library and the 8-bit PCRE2 library. + +(12) If you want to use the pcre2grep command, compile and link + src/pcre2grep.c; it uses only the 8-bit PCRE2 library (it does not need + the pcre2posix library). If you have built the PCRE2 library with JIT + support by defining SUPPORT_JIT in src/config.h, you can also define + SUPPORT_PCRE2GREP_JIT, which causes pcre2grep to make use of JIT (unless + it is run with --no-jit). If you define SUPPORT_PCRE2GREP_JIT without + defining SUPPORT_JIT, pcre2grep does not try to make use of JIT. + + +STACK SIZE IN WINDOWS ENVIRONMENTS + +Prior to release 10.30 the default system stack size of 1MiB in some Windows +environments caused issues with some tests. This should no longer be the case +for 10.30 and later releases. + + +LINKING PROGRAMS IN WINDOWS ENVIRONMENTS + +If you want to statically link a program against a PCRE2 library in the form of +a non-dll .a file, you must define PCRE2_STATIC before including src/pcre2.h. + + +CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS + +It is possible to compile programs to use different calling conventions using +MSVC. Search the web for "calling conventions" for more information. To make it +easier to change the calling convention for the exported functions in a +PCRE2 library, the macro PCRE2_CALL_CONVENTION is present in all the external +definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is +not set, it defaults to empty; the default calling convention is then used +(which is what is wanted most of the time). + + +COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE2 ON WINDOWS WITH CMAKE") + +There are two ways of building PCRE2 using the "configure, make, make install" +paradigm on Windows systems: using MinGW or using Cygwin. These are not at all +the same thing; they are completely different from each other. There is also +support for building using CMake, which some users find a more straightforward +way of building PCRE2 under Windows. + +The MinGW home page (http://www.mingw.org/) says this: + + MinGW: A collection of freely available and freely distributable Windows + specific header files and import libraries combined with GNU toolsets that + allow one to produce native Windows programs that do not rely on any + 3rd-party C runtime DLLs. + +The Cygwin home page (http://www.cygwin.com/) says this: + + Cygwin is a Linux-like environment for Windows. It consists of two parts: + + . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing + substantial Linux API functionality + + . A collection of tools which provide Linux look and feel. + +On both MinGW and Cygwin, PCRE2 should build correctly using: + + ./configure && make && make install + +This should create two libraries called libpcre2-8 and libpcre2-posix. These +are independent libraries: when you link with libpcre2-posix you must also link +with libpcre2-8, which contains the basic functions. + +Using Cygwin's compiler generates libraries and executables that depend on +cygwin1.dll. If a library that is generated this way is distributed, +cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL +licence, this forces not only PCRE2 to be under the GPL, but also the entire +application. A distributor who wants to keep their own code proprietary must +purchase an appropriate Cygwin licence. + +MinGW has no such restrictions. The MinGW compiler generates a library or +executable that can run standalone on Windows without any third party dll or +licensing issues. + +But there is more complication: + +If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is +to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a +front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's +gcc and MinGW's gcc). So, a user can: + +. Build native binaries by using MinGW or by getting Cygwin and using + -mno-cygwin. + +. Build binaries that depend on cygwin1.dll by using Cygwin with the normal + compiler flags. + +The test files that are supplied with PCRE2 are in UNIX format, with LF +characters as line terminators. Unless your PCRE2 library uses a default +newline option that includes LF as a valid newline, it may be necessary to +change the line terminators in the test files to get some of the tests to work. + + +BUILDING PCRE2 ON WINDOWS WITH CMAKE + +CMake is an alternative configuration facility that can be used instead of +"configure". CMake creates project files (make files, solution files, etc.) +tailored to numerous development environments, including Visual Studio, +Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no +spaces in the names for your CMake installation and your PCRE2 source and build +directories. + +The following instructions were contributed by a PCRE1 user, but they should +also work for PCRE2. If they are not followed exactly, errors may occur. In the +event that errors do occur, it is recommended that you delete the CMake cache +before attempting to repeat the CMake build process. In the CMake GUI, the +cache can be deleted by selecting "File > Delete Cache". + +1. Install the latest CMake version available from http://www.cmake.org/, and + ensure that cmake\bin is on your path. + +2. Unzip (retaining folder structure) the PCRE2 source tree into a source + directory such as C:\pcre2. You should ensure your local date and time + is not earlier than the file dates in your source dir if the release is + very new. + +3. Create a new, empty build directory, preferably a subdirectory of the + source dir. For example, C:\pcre2\pcre2-xx\build. + +4. Run cmake-gui from the Shell environment of your build tool, for example, + Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++. Do not try + to start Cmake from the Windows Start menu, as this can lead to errors. + +5. Enter C:\pcre2\pcre2-xx and C:\pcre2\pcre2-xx\build for the source and + build directories, respectively. + +6. Hit the "Configure" button. + +7. Select the particular IDE / build tool that you are using (Visual + Studio, MSYS makefiles, MinGW makefiles, etc.) + +8. The GUI will then list several configuration options. This is where + you can disable Unicode support or select other PCRE2 optional features. + +9. Hit "Configure" again. The adjacent "Generate" button should now be + active. + +10. Hit "Generate". + +11. The build directory should now contain a usable build system, be it a + solution file for Visual Studio, makefiles for MinGW, etc. Exit from + cmake-gui and use the generated build system with your compiler or IDE. + E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE2 + solution, select the desired configuration (Debug, or Release, etc.) and + build the ALL_BUILD project. + +12. If during configuration with cmake-gui you've elected to build the test + programs, you can execute them by building the test project. E.g., for + MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The + most recent build configuration is targeted by the tests. A summary of + test results is presented. Complete test output is subsequently + available for review in Testing\Temporary under your build dir. + + +BUILDING PCRE2 ON WINDOWS WITH VISUAL STUDIO + +The code currently cannot be compiled without an inttypes.h header, which is +available only with Visual Studio 2013 or newer. However, this portable and +permissively-licensed implementation of the stdint.h header could be used as an +alternative: + + http://www.azillionmonkeys.com/qed/pstdint.h + +Just rename it and drop it into the top level of the build tree. + + +TESTING WITH RUNTEST.BAT + +If configured with CMake, building the test project ("make test" or building +ALL_TESTS in Visual Studio) creates (and runs) pcre2_test.bat (and depending +on your configuration options, possibly other test programs) in the build +directory. The pcre2_test.bat script runs RunTest.bat with correct source and +exe paths. + +For manual testing with RunTest.bat, provided the build dir is a subdirectory +of the source directory: Open command shell window. Chdir to the location +of your pcre2test.exe and pcre2grep.exe programs. Call RunTest.bat with +"..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate. + +To run only a particular test with RunTest.Bat provide a test number argument. + +Otherwise: + +1. Copy RunTest.bat into the directory where pcre2test.exe and pcre2grep.exe + have been created. + +2. Edit RunTest.bat to identify the full or relative location of + the pcre2 source (wherein which the testdata folder resides), e.g.: + + set srcdir=C:\pcre2\pcre2-10.00 + +3. In a Windows command environment, chdir to the location of your bat and + exe programs. + +4. Run RunTest.bat. Test outputs will automatically be compared to expected + results, and discrepancies will be identified in the console output. + +To independently test the just-in-time compiler, run pcre2_jit_test.exe. + + +BUILDING PCRE2 ON NATIVE Z/OS AND Z/VM + +z/OS and z/VM are operating systems for mainframe computers, produced by IBM. +The character code used is EBCDIC, not ASCII or Unicode. In z/OS, UNIX APIs and +applications can be supported through UNIX System Services, and in such an +environment it should be possible to build PCRE2 in the same way as in other +systems, with the EBCDIC related configuration settings, but it is not known if +anybody has tried this. + +In native z/OS (without UNIX System Services) and in z/VM, special ports are +required. For details, please see file 939 on this web site: + + http://www.cbttape.org + +Everything in that location, source and executable, is in EBCDIC and native +z/OS file formats. The port provides an API for LE languages such as COBOL and +for the z/OS and z/VM versions of the Rexx languages. + + +BUILDING PCRE2 UNDER VMS + +Alexey Chuphin has contributed some auxiliary files for building PCRE2 under +OpenVMS. They are in the "vms" directory in the distribution tarball. Please +read the file called vms/openvms_readme.txt. The pcre2test and pcre2grep +programs contain some VMS-specific code. + +=========================== +Last Updated: 16 April 2024 +=========================== diff --git a/PrepareRelease b/PrepareRelease new file mode 100755 index 0000000..0dc6e30 --- /dev/null +++ b/PrepareRelease @@ -0,0 +1,257 @@ +#/bin/sh + +# Script to prepare the files for building a PCRE2 release.

Since its initial release in 2015, there has been further development of +the code and it now differs from PCRE1 in more than just the API. There are new +features, and the internals have been improved. The original PCRE1 library is +now obsolete and no longer maintained. The latest release of PCRE2 is available +in .tar.gz, tar.bz2, or .zip form from this GitHub repository: + +https://github.com/PCRE2Project/pcre2/releases + +There is a mailing list for discussion about the development of PCRE2 at +pcre2-dev@googlegroups.com.

The +contents of this README file are: + + The PCRE2 APIs + Documentation for PCRE2 + Building PCRE2 on non-Unix-like systems + Building PCRE2 without using autotools + Building PCRE2 using autotools + Retrieving configuration information + Shared libraries + Cross-compiling using autotools + Making new tarballs + Testing PCRE2 + Character tables + File manifest + + +The PCRE2 APIs +-------------- + +PCRE2 is written in C, and it has its own API. There are three sets of +functions, one for the 8-bit library, which processes strings of bytes, one for +the 16-bit library, which processes strings of 16-bit values, and one for the +32-bit library, which processes strings of 32-bit values. Unlike PCRE1, there +are no C++ wrappers. + +The distribution does contain a set of C wrapper functions for the 8-bit +library that are based on the POSIX regular expression API (see the pcre2posix +man page). These are built into a library called libpcre2-posix. Note that this +just provides a POSIX calling interface to PCRE2; the regular expressions +themselves still follow Perl syntax and semantics. The POSIX API is restricted, +and does not give full access to all of PCRE2's facilities. + +The header file for the POSIX-style functions is called pcre2posix.h. The +official POSIX name is regex.h, but I did not want to risk possible problems +with existing files of that name by distributing it that way. To use PCRE2 with +an existing program that uses the POSIX API, pcre2posix.h will have to be +renamed or pointed at by a link (or the program modified, of course). See the +pcre2posix documentation for more details. + + +Documentation for PCRE2 +----------------------- + +If you install PCRE2 in the normal way on a Unix-like system, you will end up +with a set of man pages whose names all start with "pcre2". The one that is +just called "pcre2" lists all the others. In addition to these man pages, the +PCRE2 documentation is supplied in two other forms: + + 1. There are files called doc/pcre2.txt, doc/pcre2grep.txt, and + doc/pcre2test.txt in the source distribution. The first of these is a + concatenation of the text forms of all the section 3 man pages except the + listing of pcre2demo.c and those that summarize individual functions. The + other two are the text forms of the section 1 man pages for the pcre2grep + and pcre2test commands. These text forms are provided for ease of scanning + with text editors or similar tools. They are installed in + /share/doc/pcre2, where is the installation prefix + (defaulting to /usr/local). + + 2. A set of files containing all the documentation in HTML form, hyperlinked + in various ways, and rooted in a file called index.html, is distributed in + doc/html and installed in /share/doc/pcre2/html. + + +Building PCRE2 on non-Unix-like systems +--------------------------------------- + +For a non-Unix-like system, please read the file NON-AUTOTOOLS-BUILD, though if +your system supports the use of "configure" and "make" you may be able to build +PCRE2 using autotools in the same way as for many Unix-like systems. + +PCRE2 can also be configured using CMake, which can be run in various ways +(command line, GUI, etc). This creates Makefiles, solution files, etc. The file +NON-AUTOTOOLS-BUILD has information about CMake. + +PCRE2 has been compiled on many different operating systems. It should be +straightforward to build PCRE2 on any system that has a Standard C compiler and +library, because it uses only Standard C functions. + + +Building PCRE2 without using autotools +-------------------------------------- + +The use of autotools (in particular, libtool) is problematic in some +environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD +file for ways of building PCRE2 without using autotools. + + +Building PCRE2 using autotools +------------------------------ + +The following instructions assume the use of the widely used "configure; make; +make install" (autotools) process. + +If you have downloaded and unpacked a PCRE2 release tarball, run the +"configure" command from the PCRE2 directory, with your current directory set +to the directory where you want the files to be created. This command is a +standard GNU "autoconf" configuration script, for which generic instructions +are supplied in the file INSTALL. + +The files in the GitHub repository do not contain "configure". If you have +downloaded the PCRE2 source files from GitHub, before you can run "configure" +you must run the shell script called autogen.sh. This runs a number of +autotools to create a "configure" script (you must of course have the autotools +commands installed in order to do this). + +Most commonly, people build PCRE2 within its own distribution directory, and in +this case, on many systems, just running "./configure" is sufficient. However, +the usual methods of changing standard defaults are available. For example: + +CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local + +This command specifies that the C compiler should be run with the flags '-O2 +-Wall' instead of the default, and that "make install" should install PCRE2 +under /opt/local instead of the default /usr/local. + +If you want to build in a different directory, just run "configure" with that +directory as current. For example, suppose you have unpacked the PCRE2 source +into /source/pcre2/pcre2-xxx, but you want to build it in +/build/pcre2/pcre2-xxx: + +cd /build/pcre2/pcre2-xxx +/source/pcre2/pcre2-xxx/configure + +PCRE2 is written in C and is normally compiled as a C library. However, it is +possible to build it as a C++ library, though the provided building apparatus +does not have any features to support this. + +There are some optional features that can be included or omitted from the PCRE2 +library. They are also documented in the pcre2build man page. + +. By default, both shared and static libraries are built. You can change this + by adding one of these options to the "configure" command: + + --disable-shared + --disable-static + + Setting --disable-shared ensures that PCRE2 libraries are built as static + libraries. The binaries that are then created as part of the build process + (for example, pcre2test and pcre2grep) are linked statically with one or more + PCRE2 libraries, but may also be dynamically linked with other libraries such + as libc. If you want these binaries to be fully statically linked, you can + set LDFLAGS like this: + + LDFLAGS=--static ./configure --disable-shared + + Note the two hyphens in --static. Of course, this works only if static + versions of all the relevant libraries are available for linking. See also + "Shared libraries" below. + +. By default, only the 8-bit library is built. If you add --enable-pcre2-16 to + the "configure" command, the 16-bit library is also built. If you add + --enable-pcre2-32 to the "configure" command, the 32-bit library is also + built. If you want only the 16-bit or 32-bit library, use --disable-pcre2-8 + to disable building the 8-bit library. + +. If you want to include support for just-in-time (JIT) compiling, which can + give large performance improvements on certain platforms, add --enable-jit to + the "configure" command. This support is available only for certain hardware + architectures. If you try to enable it on an unsupported architecture, there + will be a compile time error. If in doubt, use --enable-jit=auto, which + enables JIT only if the current hardware is supported. + +. If you are enabling JIT under SELinux environment you may also want to add + --enable-jit-sealloc, which enables the use of an executable memory allocator + that is compatible with SELinux. Warning: this allocator is experimental! + It does not support fork() operation and may crash when no disk space is + available. This option has no effect if JIT is disabled. + +. If you do not want to make use of the default support for UTF-8 Unicode + character strings in the 8-bit library, UTF-16 Unicode character strings in + the 16-bit library, or UTF-32 Unicode character strings in the 32-bit + library, you can add --disable-unicode to the "configure" command. This + reduces the size of the libraries. It is not possible to configure one + library with Unicode support, and another without, in the same configuration. + It is also not possible to use --enable-ebcdic (see below) with Unicode + support, so if this option is set, you must also use --disable-unicode. + + When Unicode support is available, the use of a UTF encoding still has to be + enabled by setting the PCRE2_UTF option at run time or starting a pattern + with (*UTF). When PCRE2 is compiled with Unicode support, its input can only + either be ASCII or UTF-8/16/32, even when running on EBCDIC platforms. + + As well as supporting UTF strings, Unicode support includes support for the + \P, \p, and \X sequences that recognize Unicode character properties. + However, only a subset of Unicode properties are supported; see the + pcre2pattern man page for details. Escape sequences such as \d and \w in + patterns do not by default make use of Unicode properties, but can be made to + do so by setting the PCRE2_UCP option or starting a pattern with (*UCP). + +. You can build PCRE2 to recognize either CR or LF or the sequence CRLF, or any + of the preceding, or any of the Unicode newline sequences, or the NUL (zero) + character as indicating the end of a line. Whatever you specify at build time + is the default; the caller of PCRE2 can change the selection at run time. The + default newline indicator is a single LF character (the Unix standard). You + can specify the default newline indicator by adding --enable-newline-is-cr, + --enable-newline-is-lf, --enable-newline-is-crlf, + --enable-newline-is-anycrlf, --enable-newline-is-any, or + --enable-newline-is-nul to the "configure" command, respectively. + +. By default, the sequence \R in a pattern matches any Unicode line ending + sequence. This is independent of the option specifying what PCRE2 considers + to be the end of a line (see above). However, the caller of PCRE2 can + restrict \R to match only CR, LF, or CRLF. You can make this the default by + adding --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R"). + +. In a pattern, the escape sequence \C matches a single code unit, even in a + UTF mode. This can be dangerous because it breaks up multi-code-unit + characters. You can build PCRE2 with the use of \C permanently locked out by + adding --enable-never-backslash-C (note the upper case C) to the "configure" + command. When \C is allowed by the library, individual applications can lock + it out by calling pcre2_compile() with the PCRE2_NEVER_BACKSLASH_C option. + +. PCRE2 has a counter that limits the depth of nesting of parentheses in a + pattern. This limits the amount of system stack that a pattern uses when it + is compiled. The default is 250, but you can change it by setting, for + example, + + --with-parens-nest-limit=500 + +. PCRE2 has a counter that can be set to limit the amount of computing resource + it uses when matching a pattern. If the limit is exceeded during a match, the + match fails. The default is ten million. You can change the default by + setting, for example, + + --with-match-limit=500000 + + on the "configure" command. This is just the default; individual calls to + pcre2_match() or pcre2_dfa_match() can supply their own value. There is more + discussion in the pcre2api man page (search for pcre2_set_match_limit). + +. There is a separate counter that limits the depth of nested backtracking + (pcre2_match()) or nested function calls (pcre2_dfa_match()) during a + matching process, which indirectly limits the amount of heap memory that is + used, and in the case of pcre2_dfa_match() the amount of stack as well. This + counter also has a default of ten million, which is essentially "unlimited". + You can change the default by setting, for example, + + --with-match-limit-depth=5000 + + There is more discussion in the pcre2api man page (search for + pcre2_set_depth_limit). + +. You can also set an explicit limit on the amount of heap memory used by + the pcre2_match() and pcre2_dfa_match() interpreters: + + --with-heap-limit=500 + + The units are kibibytes (units of 1024 bytes). This limit does not apply when + the JIT optimization (which has its own memory control features) is used. + There is more discussion on the pcre2api man page (search for + pcre2_set_heap_limit). + +. In the 8-bit library, the default maximum compiled pattern size is around + 64 kibibytes. You can increase this by adding --with-link-size=3 to the + "configure" command. PCRE2 then uses three bytes instead of two for offsets + to different parts of the compiled pattern. In the 16-bit library, + --with-link-size=3 is the same as --with-link-size=4, which (in both + libraries) uses four-byte offsets. Increasing the internal link size reduces + performance in the 8-bit and 16-bit libraries. In the 32-bit library, the + link size setting is ignored, as 4-byte offsets are always used. + +. Lookbehind assertions in which one or more branches can match a variable + number of characters are supported only if there is a maximum matching length + for each top-level branch. There is a limit to this maximum that defaults to + 255 characters. You can alter this default by a setting such as + + --with-max-varlookbehind=100 + + The limit can be changed at runtime by calling pcre2_set_max_varlookbehind(). + Lookbehind assertions in which every branch matches a fixed number of + characters (not necessarily all the same) are not constrained by this limit. + +. For speed, PCRE2 uses four tables for manipulating and identifying characters + whose code point values are less than 256. By default, it uses a set of + tables for ASCII encoding that is part of the distribution. If you specify + + --enable-rebuild-chartables + + a program called pcre2_dftables is compiled and run in the default C locale + when you obey "make". It builds a source file called pcre2_chartables.c. If + you do not specify this option, pcre2_chartables.c is created as a copy of + pcre2_chartables.c.dist. See "Character tables" below for further + information. + +. It is possible to compile PCRE2 for use on systems that use EBCDIC as their + character code (as opposed to ASCII/Unicode) by specifying + + --enable-ebcdic --disable-unicode + + This automatically implies --enable-rebuild-chartables (see above). However, + when PCRE2 is built this way, it always operates in EBCDIC. It cannot support + both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25, + which specifies that the code value for the EBCDIC NL character is 0x25 + instead of the default 0x15. + +. If you specify --enable-debug, additional debugging code is included in the + build. This option is intended for use by the PCRE2 maintainers. + +. In environments where valgrind is installed, if you specify + + --enable-valgrind + + PCRE2 will use valgrind annotations to mark certain memory regions as + unaddressable. This allows it to detect invalid memory accesses, and is + mostly useful for debugging PCRE2 itself. + +. In environments where the gcc compiler is used and lcov is installed, if you + specify + + --enable-coverage + + the build process implements a code coverage report for the test suite. The + report is generated by running "make coverage". If ccache is installed on + your system, it must be disabled when building PCRE2 for coverage reporting. + You can do this by setting the environment variable CCACHE_DISABLE=1 before + running "make" to build PCRE2. There is more information about coverage + reporting in the "pcre2build" documentation. + +. When JIT support is enabled, pcre2grep automatically makes use of it, unless + you add --disable-pcre2grep-jit to the "configure" command. + +. There is support for calling external programs during matching in the + pcre2grep command, using PCRE2's callout facility with string arguments. This + support can be disabled by adding --disable-pcre2grep-callout to the + "configure" command. There are two kinds of callout: one that generates + output from inbuilt code, and another that calls an external program. The + latter has special support for Windows and VMS; otherwise it assumes the + existence of the fork() function. This facility can be disabled by adding + --disable-pcre2grep-callout-fork to the "configure" command. + +. The pcre2grep program currently supports only 8-bit data files, and so + requires the 8-bit PCRE2 library. It is possible to compile pcre2grep to use + libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by + specifying one or both of + + --enable-pcre2grep-libz + --enable-pcre2grep-libbz2 + + Of course, the relevant libraries must be installed on your system. + +. The default starting size (in bytes) of the internal buffer used by pcre2grep + can be set by, for example: + + --with-pcre2grep-bufsize=51200 + + The value must be a plain integer. The default is 20480. The amount of memory + used by pcre2grep is actually three times this number, to allow for "before" + and "after" lines. If very long lines are encountered, the buffer is + automatically enlarged, up to a fixed maximum size. + +. The default maximum size of pcre2grep's internal buffer can be set by, for + example: + + --with-pcre2grep-max-bufsize=2097152 + + The default is either 1048576 or the value of --with-pcre2grep-bufsize, + whichever is the larger. + +. It is possible to compile pcre2test so that it links with the libreadline + or libedit libraries, by specifying, respectively, + + --enable-pcre2test-libreadline or --enable-pcre2test-libedit + + If this is done, when pcre2test's input is from a terminal, it reads it using + the readline() function. This provides line-editing and history facilities. + Note that libreadline is GPL-licenced, so if you distribute a binary of + pcre2test linked in this way, there may be licensing issues. These can be + avoided by linking with libedit (which has a BSD licence) instead. + + Enabling libreadline causes the -lreadline option to be added to the + pcre2test build. In many operating environments with a system-installed + readline library this is sufficient. However, in some environments (e.g. if + an unmodified distribution version of readline is in use), it may be + necessary to specify something like LIBS="-lncurses" as well. This is + because, to quote the readline INSTALL, "Readline uses the termcap functions, + but does not link with the termcap or curses library itself, allowing + applications which link with readline the option to choose an appropriate + library." If you get error messages about missing functions tgetstr, tgetent, + tputs, tgetflag, or tgoto, this is the problem, and linking with the ncurses + library should fix it. + +. The C99 standard defines formatting modifiers z and t for size_t and + ptrdiff_t values, respectively. By default, PCRE2 uses these modifiers in + environments other than Microsoft Visual Studio versions earlier than 2013 + when __STDC_VERSION__ is defined and has a value greater than or equal to + 199901L (indicating C99). However, there is at least one environment that + claims to be C99 but does not support these modifiers. If + --disable-percent-zt is specified, no use is made of the z or t modifiers. + Instead of %td or %zu, %lu is used, with a cast for size_t values. + +. There is a special option called --enable-fuzz-support for use by people who + want to run fuzzing tests on PCRE2. At present this applies only to the 8-bit + library. If set, it causes an extra library called libpcre2-fuzzsupport.a to + be built, but not installed. This contains a single function called + LLVMFuzzerTestOneInput() whose arguments are a pointer to a string and the + length of the string. When called, this function tries to compile the string + as a pattern, and if that succeeds, to match it. This is done both with no + options and with some random options bits that are generated from the string. + Setting --enable-fuzz-support also causes a binary called pcre2fuzzcheck to + be created. This is normally run under valgrind or used when PCRE2 is + compiled with address sanitizing enabled. It calls the fuzzing function and + outputs information about what it is doing. The input strings are specified + by arguments: if an argument starts with "=" the rest of it is a literal + input string. Otherwise, it is assumed to be a file name, and the contents + of the file are the test string. + +. Releases before 10.30 could be compiled with --disable-stack-for-recursion, + which caused pcre2_match() to use individual blocks on the heap for + backtracking instead of recursive function calls (which use the stack). This + is now obsolete because pcre2_match() was refactored always to use the heap + (in a much more efficient way than before). This option is retained for + backwards compatibility, but has no effect other than to output a warning. + +The "configure" script builds the following files for the basic C library: + +. Makefile the makefile that builds the library +. src/config.h build-time configuration options for the library +. src/pcre2.h the public PCRE2 header file +. pcre2-config script that shows the building settings such as CFLAGS + that were set for "configure" +. libpcre2-8.pc ) +. libpcre2-16.pc ) data for the pkg-config command +. libpcre2-32.pc ) +. libpcre2-posix.pc ) +. libtool script that builds shared and/or static libraries + +Versions of config.h and pcre2.h are distributed in the src directory of PCRE2 +tarballs under the names config.h.generic and pcre2.h.generic. These are +provided for those who have to build PCRE2 without using "configure" or CMake. +If you use "configure" or CMake, the .generic versions are not used. + +The "configure" script also creates config.status, which is an executable +script that can be run to recreate the configuration, and config.log, which +contains compiler output from tests that "configure" runs. + +Once "configure" has run, you can run "make". This builds whichever of the +libraries libpcre2-8, libpcre2-16 and libpcre2-32 are configured, and a test +program called pcre2test. If you enabled JIT support with --enable-jit, another +test program called pcre2_jit_test is built as well. If the 8-bit library is +built, libpcre2-posix, pcre2posix_test, and the pcre2grep command are also +built. Running "make" with the -j option may speed up compilation on +multiprocessor systems. + +The command "make check" runs all the appropriate tests. Details of the PCRE2 +tests are given below in a separate section of this document. The -j option of +"make" can also be used when running the tests. + +You can use "make install" to install PCRE2 into live directories on your +system. The following are installed (file names are all relative to the + that is set when "configure" is run): + + Commands (bin): + pcre2test + pcre2grep (if 8-bit support is enabled) + pcre2-config + + Libraries (lib): + libpcre2-8 (if 8-bit support is enabled) + libpcre2-16 (if 16-bit support is enabled) + libpcre2-32 (if 32-bit support is enabled) + libpcre2-posix (if 8-bit support is enabled) + + Configuration information (lib/pkgconfig): + libpcre2-8.pc + libpcre2-16.pc + libpcre2-32.pc + libpcre2-posix.pc + + Header files (include): + pcre2.h + pcre2posix.h + + Man pages (share/man/man{1,3}): + pcre2grep.1 + pcre2test.1 + pcre2-config.1 + pcre2.3 + pcre2*.3 (lots more pages, all starting "pcre2") + + HTML documentation (share/doc/pcre2/html): + index.html + *.html (lots more pages, hyperlinked from index.html) + + Text file documentation (share/doc/pcre2): + AUTHORS + COPYING + ChangeLog + LICENCE + NEWS + README + pcre2.txt (a concatenation of the man(3) pages) + pcre2test.txt the pcre2test man page + pcre2grep.txt the pcre2grep man page + pcre2-config.txt the pcre2-config man page + +If you want to remove PCRE2 from your system, you can run "make uninstall". +This removes all the files that "make install" installed. However, it does not +remove any directories, because these are often shared with other programs. + + +Retrieving configuration information +------------------------------------ + +Running "make install" installs the command pcre2-config, which can be used to +recall information about the PCRE2 configuration and installation. For example: + + pcre2-config --version + +prints the version number, and + + pcre2-config --libs8 + +outputs information about where the 8-bit library is installed. This command +can be included in makefiles for programs that use PCRE2, saving the programmer +from having to remember too many details. Run pcre2-config with no arguments to +obtain a list of possible arguments. + +The pkg-config command is another system for saving and retrieving information +about installed libraries. Instead of separate commands for each library, a +single command is used. For example: + + pkg-config --libs libpcre2-16 + +The data is held in *.pc files that are installed in a directory called +/lib/pkgconfig. + + +Shared libraries +---------------- + +The default distribution builds PCRE2 as shared libraries and static libraries, +as long as the operating system supports shared libraries. Shared library +support relies on the "libtool" script which is built as part of the +"configure" process. + +The libtool script is used to compile and link both shared and static +libraries. They are placed in a subdirectory called .libs when they are newly +built. The programs pcre2test and pcre2grep are built to use these uninstalled +libraries (by means of wrapper scripts in the case of shared libraries). When +you use "make install" to install shared libraries, pcre2grep and pcre2test are +automatically re-built to use the newly installed shared libraries before being +installed themselves. However, the versions left in the build directory still +use the uninstalled libraries. + +To build PCRE2 using static libraries only you must use --disable-shared when +configuring it. For example: + +./configure --prefix=/usr/gnu --disable-shared + +Then run "make" in the usual way. Similarly, you can use --disable-static to +build only shared libraries. Note, however, that when you build only static +libraries, binary programs such as pcre2test and pcre2grep may still be +dynamically linked with other libraries (for example, libc) unless you set +LDFLAGS to --static when running "configure". + + +Cross-compiling using autotools +------------------------------- + +You can specify CC and CFLAGS in the normal way to the "configure" command, in +order to cross-compile PCRE2 for some other host. However, you should NOT +specify --enable-rebuild-chartables, because if you do, the pcre2_dftables.c +source file is compiled and run on the local host, in order to generate the +inbuilt character tables (the pcre2_chartables.c file). This will probably not +work, because pcre2_dftables.c needs to be compiled with the local compiler, +not the cross compiler. + +When --enable-rebuild-chartables is not specified, pcre2_chartables.c is +created by making a copy of pcre2_chartables.c.dist, which is a default set of +tables that assumes ASCII code. Cross-compiling with the default tables should +not be a problem. + +If you need to modify the character tables when cross-compiling, you should +move pcre2_chartables.c.dist out of the way, then compile pcre2_dftables.c by +hand and run it on the local host to make a new version of +pcre2_chartables.c.dist. See the pcre2build section "Creating character tables +at build time" for more details. + + +Making new tarballs +------------------- + +The command "make dist" creates three PCRE2 tarballs, in tar.gz, tar.bz2, and +zip formats. The command "make distcheck" does the same, but then does a trial +build of the new distribution to ensure that it works. + +If you have modified any of the man page sources in the doc directory, you +should first run the PrepareRelease script before making a distribution. This +script creates the .txt and HTML forms of the documentation from the man pages. + + +Testing PCRE2 +------------- + +To test the basic PCRE2 library on a Unix-like system, run the RunTest script. +There is another script called RunGrepTest that tests the pcre2grep command. +When the 8-bit library is built, a test program for the POSIX wrapper, called +pcre2posix_test, is compiled, and when JIT support is enabled, a test program +called pcre2_jit_test is built. The scripts and the program tests are all run +when you obey "make check". For other environments, see the instructions in +NON-AUTOTOOLS-BUILD. + +The RunTest script runs the pcre2test test program (which is documented in its +own man page) on each of the relevant testinput files in the testdata +directory, and compares the output with the contents of the corresponding +testoutput files. RunTest uses a file called testtry to hold the main output +from pcre2test. Other files whose names begin with "test" are used as working +files in some tests. + +Some tests are relevant only when certain build-time options were selected. For +example, the tests for UTF-8/16/32 features are run only when Unicode support +is available. RunTest outputs a comment when it skips a test. + +Many (but not all) of the tests that are not skipped are run twice if JIT +support is available. On the second run, JIT compilation is forced. This +testing can be suppressed by putting "-nojit" on the RunTest command line. + +The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit +libraries that are enabled. If you want to run just one set of tests, call +RunTest with either the -8, -16 or -32 option. + +If valgrind is installed, you can run the tests under it by putting "-valgrind" +on the RunTest command line. To run pcre2test on just one or more specific test +files, give their numbers as arguments to RunTest, for example: + + RunTest 2 7 11 + +You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the +end), or a number preceded by ~ to exclude a test. For example: + + Runtest 3-15 ~10 + +This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests +except test 13. Whatever order the arguments are in, the tests are always run +in numerical order. + +You can also call RunTest with the single argument "list" to cause it to output +a list of tests. + +The test sequence starts with "test 0", which is a special test that has no +input file, and whose output is not checked. This is because it will be +different on different hardware and with different configurations. The test +exists in order to exercise some of pcre2test's code that would not otherwise +be run. + +Tests 1 and 2 can always be run, as they expect only plain text strings (not +UTF) and make no use of Unicode properties. The first test file can be fed +directly into the perltest.sh script to check that Perl gives the same results. +The only difference you should see is in the first few lines, where the Perl +version is given instead of the PCRE2 version. The second set of tests check +auxiliary functions, error detection, and run-time flags that are specific to +PCRE2. It also uses the debugging flags to check some of the internals of +pcre2_compile(). + +If you build PCRE2 with a locale setting that is not the standard C locale, the +character tables may be different (see next paragraph). In some cases, this may +cause failures in the second set of tests. For example, in a locale where the +isprint() function yields TRUE for characters in the range 128-255, the use of +[:isascii:] inside a character class defines a different set of characters, and +this shows up in this test as a difference in the compiled code, which is being +listed for checking. For example, where the comparison test output contains +[\x00-\x7f] the test might contain [\x00-\xff], and similarly in some other +cases. This is not a bug in PCRE2. + +Test 3 checks pcre2_maketables(), the facility for building a set of character +tables for a specific locale and using them instead of the default tables. The +script uses the "locale" command to check for the availability of the "fr_FR", +"french", or "fr" locale, and uses the first one that it finds. If the "locale" +command fails, or if its output doesn't include "fr_FR", "french", or "fr" in +the list of available locales, the third test cannot be run, and a comment is +output to say why. If running this test produces an error like this: + + ** Failed to set locale "fr_FR" + +it means that the given locale is not available on your system, despite being +listed by "locale". This does not mean that PCRE2 is broken. There are three +alternative output files for the third test, because three different versions +of the French locale have been encountered. The test passes if its output +matches any one of them. + +Tests 4 and 5 check UTF and Unicode property support, test 4 being compatible +with the perltest.sh script, and test 5 checking PCRE2-specific things. + +Tests 6 and 7 check the pcre2_dfa_match() alternative matching function, in +non-UTF mode and UTF-mode with Unicode property support, respectively. + +Test 8 checks some internal offsets and code size features, but it is run only +when Unicode support is enabled. The output is different in 8-bit, 16-bit, and +32-bit modes and for different link sizes, so there are different output files +for each mode and link size. + +Tests 9 and 10 are run only in 8-bit mode, and tests 11 and 12 are run only in +16-bit and 32-bit modes. These are tests that generate different output in +8-bit mode. Each pair are for general cases and Unicode support, respectively. + +Test 13 checks the handling of non-UTF characters greater than 255 by +pcre2_dfa_match() in 16-bit and 32-bit modes. + +Test 14 contains some special UTF and UCP tests that give different output for +different code unit widths. + +Test 15 contains a number of tests that must not be run with JIT. They check, +among other non-JIT things, the match-limiting features of the interpretive +matcher. + +Test 16 is run only when JIT support is not available. It checks that an +attempt to use JIT has the expected behaviour. + +Test 17 is run only when JIT support is available. It checks JIT complete and +partial modes, match-limiting under JIT, and other JIT-specific features. + +Tests 18 and 19 are run only in 8-bit mode. They check the POSIX interface to +the 8-bit library, without and with Unicode support, respectively. + +Test 20 checks the serialization functions by writing a set of compiled +patterns to a file, and then reloading and checking them. + +Tests 21 and 22 test \C support when the use of \C is not locked out, without +and with UTF support, respectively. Test 23 tests \C when it is locked out. + +Tests 24 and 25 test the experimental pattern conversion functions, without and +with UTF support, respectively. + +Test 26 checks Unicode property support using tests that are generated +automatically from the Unicode data tables. + + +Character tables +---------------- + +For speed, PCRE2 uses four tables for manipulating and identifying characters +whose code point values are less than 256. By default, a set of tables that is +built into the library is used. The pcre2_maketables() function can be called +by an application to create a new set of tables in the current locale. This are +passed to PCRE2 by calling pcre2_set_character_tables() to put a pointer into a +compile context. + +The source file called pcre2_chartables.c contains the default set of tables. +By default, this is created as a copy of pcre2_chartables.c.dist, which +contains tables for ASCII coding. However, if --enable-rebuild-chartables is +specified for ./configure, a new version of pcre2_chartables.c is built by the +program pcre2_dftables (compiled from pcre2_dftables.c), which uses the ANSI C +character handling functions such as isalnum(), isalpha(), isupper(), +islower(), etc. to build the table sources. This means that the default C +locale that is set for your system will control the contents of these default +tables. You can change the default tables by editing pcre2_chartables.c and +then re-building PCRE2. If you do this, you should take care to ensure that the +file does not get automatically re-generated. The best way to do this is to +move pcre2_chartables.c.dist out of the way and replace it with your customized +tables. + +When the pcre2_dftables program is run as a result of specifying +--enable-rebuild-chartables, it uses the default C locale that is set on your +system. It does not pay attention to the LC_xxx environment variables. In other +words, it uses the system's default locale rather than whatever the compiling +user happens to have set. If you really do want to build a source set of +character tables in a locale that is specified by the LC_xxx variables, you can +run the pcre2_dftables program by hand with the -L option. For example: + + ./pcre2_dftables -L pcre2_chartables.c.special + +The second argument names the file where the source code for the tables is +written. The first two 256-byte tables provide lower casing and case flipping +functions, respectively. The next table consists of a number of 32-byte bit +maps which identify certain character classes such as digits, "word" +characters, white space, etc. These are used when building 32-byte bit maps +that represent character classes for code points less than 256. The final +256-byte table has bits indicating various character types, as follows: + + 1 white space character + 2 letter + 4 lower case letter + 8 decimal digit + 16 alphanumeric or '_' + +You can also specify -b (with or without -L) when running pcre2_dftables. This +causes the tables to be written in binary instead of as source code. A set of +binary tables can be loaded into memory by an application and passed to +pcre2_compile() in the same way as tables created dynamically by calling +pcre2_maketables(). The tables are just a string of bytes, independent of +hardware characteristics such as endianness. This means they can be bundled +with an application that runs in different environments, to ensure consistent +behaviour. + +See also the pcre2build section "Creating character tables at build time".

The appropriate tests are +# selected, depending on which build-time options were used. +# +# When JIT support is available, all appropriate tests are run with and without +# JIT, unless "-nojit" is given on the command line. There are also two tests +# for JIT-specific features, one to be run when JIT support is available +# (unless "-nojit" is specified), and one when it is not. +# +# Whichever of the 8-, 16- and 32-bit libraries exist are tested. It is also +# possible to select which to test by giving "-8", "-16" or "-32" on the +# command line. +# +# As well as "-nojit", "-8", "-16", and "-32", arguments for this script are +# individual test numbers, ranges of tests such as 3-6 or 3- (meaning 3 to the +# end), or a number preceded by ~ to exclude a test. For example, "3-15 ~10" +# runs tests 3 to 15, excluding test 10, and just "~10" runs all the tests +# except test 10. Whatever order the arguments are in, these tests are always +# run in numerical order. +# +# If no specific tests are selected (which is the case when this script is run +# via 'make check') the default is to run all the numbered tests. +# +# There may also be named (as well as numbered) tests for special purposes. At +# present there is just one, called "heap". This test's output contains the +# sizes of heap frames and frame vectors, which depend on the environment. It +# is therefore not run unless explicitly requested. +# +# Inappropriate tests are automatically skipped (with a comment to say so). For +# example, if JIT support is not compiled, test 16 is skipped, whereas if JIT +# support is compiled, test 15 is skipped. +# +# Other arguments can be one of the words "-valgrind", "-valgrind-log", or +# "-sim" followed by an argument to run cross-compiled executables under a +# simulator, for example: +# +# RunTest 3 -sim "qemu-arm -s 8388608" +# +# For backwards compatibility, -nojit, -valgrind, -valgrind-log, and -sim may +# be given without the leading "-" character. +# +# When PCRE2 is compiled by clang with -fsanitize arguments, some tests need +# very much more stack than normal. In environments where the stack can be +# set at runtime, -bigstack sets a gigantic stack. +# +# There are two special cases where only one argument is allowed: +# +# If the first and only argument is "ebcdic", the script runs the special +# EBCDIC test that can be useful for checking certain EBCDIC features, even +# when run in an ASCII environment.

The README file contains information about the options for +"configure". + +There is also support for CMake, which some users prefer, especially in Windows +environments, though it can also be run in Unix-like environments. See the +section entitled "Building PCRE2 on Windows with CMake" below. + +Versions of src/config.h and src/pcre2.h are distributed in the PCRE2 tarballs +under the names src/config.h.generic and src/pcre2.h.generic. These are +provided for those who build PCRE2 without using "configure" or CMake. If you +use "configure" or CMake, the .generic versions are not used. + + +GENERIC INSTRUCTIONS FOR THE PCRE2 C LIBRARIES + +There are three possible PCRE2 libraries, each handling data with a specific +code unit width: 8, 16, or 32 bits. You can build any combination of them. The +following are generic instructions for building a PCRE2 C library "by hand". If +you are going to use CMake, this section does not apply to you; you can skip +ahead to the CMake section. Note that the settings concerned with 8-bit, +16-bit, and 32-bit code units relate to the type of data string that PCRE2 +processes. They are NOT referring to the underlying operating system bit width. +You do not have to do anything special to compile in a 64-bit environment, for +example. + + (1) Copy or rename the file src/config.h.generic as src/config.h, and edit the + macro settings that it contains to whatever is appropriate for your + environment. In particular, you can alter the definition of the NEWLINE + macro to specify what character(s) you want to be interpreted as line + terminators by default. You need to #define at least one of + SUPPORT_PCRE2_8, SUPPORT_PCRE2_16, or SUPPORT_PCRE2_32, depending on which + libraries you are going to build. You must set all that apply. + + When you subsequently compile any of the PCRE2 modules, you must specify + -DHAVE_CONFIG_H to your compiler so that src/config.h is included in the + sources. + + An alternative approach is not to edit src/config.h, but to use -D on the + compiler command line to make any changes that you need to the + configuration options. In this case -DHAVE_CONFIG_H must not be set. + + NOTE: There have been occasions when the way in which certain parameters + in src/config.h are used has changed between releases. (In the + configure/make world, this is handled automatically.) When upgrading to a + new release, you are strongly advised to review src/config.h.generic + before re-using what you had previously. + + Note also that the src/config.h.generic file is created from a config.h + that was generated by Autotools, which automatically includes settings of + a number of macros that are not actually used by PCRE2 (for example, + HAVE_DLFCN_H). + + (2) Copy or rename the file src/pcre2.h.generic as src/pcre2.h. + + (3) EITHER: + Copy or rename file src/pcre2_chartables.c.dist as + src/pcre2_chartables.c. + + OR: + Compile src/pcre2_dftables.c as a stand-alone program (using + -DHAVE_CONFIG_H if you have set up src/config.h), and then run it with + the single argument "src/pcre2_chartables.c". This generates a set of + standard character tables and writes them to that file. The tables are + generated using the default C locale for your system. If you want to use + a locale that is specified by LC_xxx environment variables, add the -L + option to the pcre2_dftables command. You must use this method if you + are building on a system that uses EBCDIC code. + + The tables in src/pcre2_chartables.c are defaults. The caller of PCRE2 can + specify alternative tables at run time. + + (4) For a library that supports 8-bit code units in the character strings that + it processes, compile the following source files from the src directory, + setting -DPCRE2_CODE_UNIT_WIDTH=8 as a compiler option. Also set + -DHAVE_CONFIG_H if you have set up src/config.h with your configuration, + or else use other -D settings to change the configuration as required. + + pcre2_auto_possess.c + pcre2_chkdint.c + pcre2_chartables.c + pcre2_compile.c + pcre2_config.c + pcre2_context.c + pcre2_convert.c + pcre2_dfa_match.c + pcre2_error.c + pcre2_extuni.c + pcre2_find_bracket.c + pcre2_jit_compile.c + pcre2_maketables.c + pcre2_match.c + pcre2_match_data.c + pcre2_newline.c + pcre2_ord2utf.c + pcre2_pattern_info.c + pcre2_script_run.c + pcre2_serialize.c + pcre2_string_utils.c + pcre2_study.c + pcre2_substitute.c + pcre2_substring.c + pcre2_tables.c + pcre2_ucd.c + pcre2_valid_utf.c + pcre2_xclass.c + + Make sure that you include -I. in the compiler command (or equivalent for + an unusual compiler) so that all included PCRE2 header files are first + sought in the src directory under the current directory. Otherwise you run + the risk of picking up a previously-installed file from somewhere else. + + Note that you must compile pcre2_jit_compile.c, even if you have not + defined SUPPORT_JIT in src/config.h, because when JIT support is not + configured, dummy functions are compiled. When JIT support IS configured, + pcre2_jit_compile.c #includes other files from the sljit subdirectory, + all of whose names begin with "sljit". It also #includes + src/pcre2_jit_match.c and src/pcre2_jit_misc.c, so you should not compile + those yourself. + + Note also that the pcre2_fuzzsupport.c file contains special code that is + useful to those who want to run fuzzing tests on the PCRE2 library. Unless + you are doing that, you can ignore it. + + (5) Now link all the compiled code into an object library in whichever form + your system keeps such libraries. This is the PCRE2 C 8-bit library, + typically called something like libpcre2-8. If your system has static and + shared libraries, you may have to do this once for each type. + + (6) If you want to build a library that supports 16-bit or 32-bit code units, + set 16 or 32 as the value of -DPCRE2_CODE_UNIT_WIDTH when obeying step 4 + above. If you want to build more than one PCRE2 library, repeat steps 4 + and 5 as necessary. + + (7) If you want to build the POSIX wrapper functions (which apply only to the + 8-bit library), ensure that you have the src/pcre2posix.h file and then + compile src/pcre2posix.c. Link the result (on its own) as the pcre2posix + library. If targeting a DLL in Windows, make sure to include + -DPCRE2POSIX_SHARED with your compiler flags. + + (8) The pcre2test program can be linked with any combination of the 8-bit, + 16-bit and 32-bit libraries (depending on what you specfied in + src/config.h) . Compile src/pcre2test.c; don't forget -DHAVE_CONFIG_H if + necessary, but do NOT define PCRE2_CODE_UNIT_WIDTH. Then link with the + appropriate library/ies. If you compiled an 8-bit library, pcre2test also + needs the pcre2posix wrapper library. + + (9) Run pcre2test on the testinput files in the testdata directory, and check + that the output matches the corresponding testoutput files. There are + comments about what each test does in the section entitled "Testing PCRE2" + in the README file. If you compiled more than one of the 8-bit, 16-bit and + 32-bit libraries, you need to run pcre2test with the -16 option to do + 16-bit tests and with the -32 option to do 32-bit tests. + + Some tests are relevant only when certain build-time options are selected. + For example, test 4 is for Unicode support, and will not run if you have + built PCRE2 without it. See the comments at the start of each testinput + file. If you have a suitable Unix-like shell, the RunTest script will run + the appropriate tests for you. The command "RunTest list" will output a + list of all the tests. + + Note that the supplied files are in Unix format, with just LF characters + as line terminators. You may need to edit them to change this if your + system uses a different convention. + +(10) If you have built PCRE2 with SUPPORT_JIT, the JIT features can be tested + by running pcre2test with the -jit option. This is done automatically by + the RunTest script. You might also like to build and run the freestanding + JIT test program, src/pcre2_jit_test.c. + +(11) The pcre2test program tests the POSIX wrapper library, but there is also a + freestanding test program in src/pcre2posix_test.c. It must be linked with + both the pcre2posix library and the 8-bit PCRE2 library. + +(12) If you want to use the pcre2grep command, compile and link + src/pcre2grep.c; it uses only the 8-bit PCRE2 library (it does not need + the pcre2posix library). If you have built the PCRE2 library with JIT + support by defining SUPPORT_JIT in src/config.h, you can also define + SUPPORT_PCRE2GREP_JIT, which causes pcre2grep to make use of JIT (unless + it is run with --no-jit). If you define SUPPORT_PCRE2GREP_JIT without + defining SUPPORT_JIT, pcre2grep does not try to make use of JIT. + + +STACK SIZE IN WINDOWS ENVIRONMENTS + +Prior to release 10.30 the default system stack size of 1MiB in some Windows +environments caused issues with some tests. This should no longer be the case +for 10.30 and later releases. + + +LINKING PROGRAMS IN WINDOWS ENVIRONMENTS + +If you want to statically link a program against a PCRE2 library in the form of +a non-dll .a file, you must define PCRE2_STATIC before including src/pcre2.h. + + +CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS + +It is possible to compile programs to use different calling conventions using +MSVC. Search the web for "calling conventions" for more information. To make it +easier to change the calling convention for the exported functions in a +PCRE2 library, the macro PCRE2_CALL_CONVENTION is present in all the external +definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is +not set, it defaults to empty; the default calling convention is then used +(which is what is wanted most of the time). + + +COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE2 ON WINDOWS WITH CMAKE") + +There are two ways of building PCRE2 using the "configure, make, make install" +paradigm on Windows systems: using MinGW or using Cygwin. These are not at all +the same thing; they are completely different from each other. There is also +support for building using CMake, which some users find a more straightforward +way of building PCRE2 under Windows. + +The MinGW home page (http://www.mingw.org/) says this: + + MinGW: A collection of freely available and freely distributable Windows + specific header files and import libraries combined with GNU toolsets that + allow one to produce native Windows programs that do not rely on any + 3rd-party C runtime DLLs. + +The Cygwin home page (http://www.cygwin.com/) says this: + + Cygwin is a Linux-like environment for Windows. It consists of two parts: + + . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing + substantial Linux API functionality + + . A collection of tools which provide Linux look and feel. + +On both MinGW and Cygwin, PCRE2 should build correctly using: + + ./configure && make && make install + +This should create two libraries called libpcre2-8 and libpcre2-posix. These +are independent libraries: when you link with libpcre2-posix you must also link +with libpcre2-8, which contains the basic functions. + +Using Cygwin's compiler generates libraries and executables that depend on +cygwin1.dll. If a library that is generated this way is distributed, +cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL +licence, this forces not only PCRE2 to be under the GPL, but also the entire +application. A distributor who wants to keep their own code proprietary must +purchase an appropriate Cygwin licence. + +MinGW has no such restrictions. The MinGW compiler generates a library or +executable that can run standalone on Windows without any third party dll or +licensing issues. + +But there is more complication: + +If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is +to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a +front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's +gcc and MinGW's gcc). So, a user can: + +. Build native binaries by using MinGW or by getting Cygwin and using + -mno-cygwin. + +. Build binaries that depend on cygwin1.dll by using Cygwin with the normal + compiler flags. + +The test files that are supplied with PCRE2 are in UNIX format, with LF +characters as line terminators. Unless your PCRE2 library uses a default +newline option that includes LF as a valid newline, it may be necessary to +change the line terminators in the test files to get some of the tests to work. + + +BUILDING PCRE2 ON WINDOWS WITH CMAKE + +CMake is an alternative configuration facility that can be used instead of +"configure". CMake creates project files (make files, solution files, etc.) +tailored to numerous development environments, including Visual Studio, +Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no +spaces in the names for your CMake installation and your PCRE2 source and build +directories. + +The following instructions were contributed by a PCRE1 user, but they should +also work for PCRE2. If they are not followed exactly, errors may occur. In the +event that errors do occur, it is recommended that you delete the CMake cache +before attempting to repeat the CMake build process. In the CMake GUI, the +cache can be deleted by selecting "File > Delete Cache". + +1. Install the latest CMake version available from http://www.cmake.org/, and + ensure that cmake\bin is on your path. + +2. Unzip (retaining folder structure) the PCRE2 source tree into a source + directory such as C:\pcre2. You should ensure your local date and time + is not earlier than the file dates in your source dir if the release is + very new. + +3. Create a new, empty build directory, preferably a subdirectory of the + source dir. For example, C:\pcre2\pcre2-xx\build. + +4. Run cmake-gui from the Shell environment of your build tool, for example, + Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++. Do not try + to start Cmake from the Windows Start menu, as this can lead to errors. + +5. Enter C:\pcre2\pcre2-xx and C:\pcre2\pcre2-xx\build for the source and + build directories, respectively. + +6. Hit the "Configure" button. + +7. Select the particular IDE / build tool that you are using (Visual + Studio, MSYS makefiles, MinGW makefiles, etc.) + +8. The GUI will then list several configuration options. This is where + you can disable Unicode support or select other PCRE2 optional features. + +9. Hit "Configure" again. The adjacent "Generate" button should now be + active. + +10. Hit "Generate". + +11. The build directory should now contain a usable build system, be it a + solution file for Visual Studio, makefiles for MinGW, etc. Exit from + cmake-gui and use the generated build system with your compiler or IDE. + E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE2 + solution, select the desired configuration (Debug, or Release, etc.) and + build the ALL_BUILD project. + +12. If during configuration with cmake-gui you've elected to build the test + programs, you can execute them by building the test project. E.g., for + MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The + most recent build configuration is targeted by the tests. A summary of + test results is presented. Complete test output is subsequently + available for review in Testing\Temporary under your build dir. + + +BUILDING PCRE2 ON WINDOWS WITH VISUAL STUDIO + +The code currently cannot be compiled without an inttypes.h header, which is +available only with Visual Studio 2013 or newer. However, this portable and +permissively-licensed implementation of the stdint.h header could be used as an +alternative: + + http://www.azillionmonkeys.com/qed/pstdint.h + +Just rename it and drop it into the top level of the build tree. + + +TESTING WITH RUNTEST.BAT + +If configured with CMake, building the test project ("make test" or building +ALL_TESTS in Visual Studio) creates (and runs) pcre2_test.bat (and depending +on your configuration options, possibly other test programs) in the build +directory. The pcre2_test.bat script runs RunTest.bat with correct source and +exe paths. + +For manual testing with RunTest.bat, provided the build dir is a subdirectory +of the source directory: Open command shell window. Chdir to the location +of your pcre2test.exe and pcre2grep.exe programs. Call RunTest.bat with +"..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate. + +To run only a particular test with RunTest.Bat provide a test number argument. + +Otherwise: + +1. Copy RunTest.bat into the directory where pcre2test.exe and pcre2grep.exe + have been created. + +2. Edit RunTest.bat to identify the full or relative location of + the pcre2 source (wherein which the testdata folder resides), e.g.: + + set srcdir=C:\pcre2\pcre2-10.00 + +3. In a Windows command environment, chdir to the location of your bat and + exe programs. + +4. Run RunTest.bat. Test outputs will automatically be compared to expected + results, and discrepancies will be identified in the console output. + +To independently test the just-in-time compiler, run pcre2_jit_test.exe. + + +BUILDING PCRE2 ON NATIVE Z/OS AND Z/VM + +z/OS and z/VM are operating systems for mainframe computers, produced by IBM. +The character code used is EBCDIC, not ASCII or Unicode. In z/OS, UNIX APIs and +applications can be supported through UNIX System Services, and in such an +environment it should be possible to build PCRE2 in the same way as in other +systems, with the EBCDIC related configuration settings, but it is not known if +anybody has tried this. + +In native z/OS (without UNIX System Services) and in z/VM, special ports are +required. For details, please see file 939 on this web site: + + http://www.cbttape.org + +Everything in that location, source and executable, is in EBCDIC and native +z/OS file formats. The port provides an API for LE languages such as COBOL and +for the z/OS and z/VM versions of the Rexx languages. + + +BUILDING PCRE2 UNDER VMS + +Alexey Chuphin has contributed some auxiliary files for building PCRE2 under +OpenVMS. They are in the "vms" directory in the distribution tarball. Please +read the file called vms/openvms_readme.txt. The pcre2test and pcre2grep +programs contain some VMS-specific code. + +=========================== +Last Updated: 16 April 2024 +=========================== diff --git a/doc/html/README.txt b/doc/html/README.txt new file mode 100644 index 0000000..dab5e94 --- /dev/null +++ b/doc/html/README.txt @@ -0,0 +1,956 @@ +README file for PCRE2 (Perl-compatible regular expression library) +------------------------------------------------------------------ + +PCRE2 is a re-working of the original PCRE1 library to provide an entirely new +API. Since its initial release in 2015, there has been further development of +the code and it now differs from PCRE1 in more than just the API. There are new +features, and the internals have been improved. The original PCRE1 library is +now obsolete and no longer maintained. The latest release of PCRE2 is available +in .tar.gz, tar.bz2, or .zip form from this GitHub repository: + +https://github.com/PCRE2Project/pcre2/releases + +There is a mailing list for discussion about the development of PCRE2 at +pcre2-dev@googlegroups.com.

There are three sets of +functions, one for the 8-bit library, which processes strings of bytes, one for +the 16-bit library, which processes strings of 16-bit values, and one for the +32-bit library, which processes strings of 32-bit values. Unlike PCRE1, there +are no C++ wrappers. + +The distribution does contain a set of C wrapper functions for the 8-bit +library that are based on the POSIX regular expression API (see the pcre2posix +man page). These are built into a library called libpcre2-posix. Note that this +just provides a POSIX calling interface to PCRE2; the regular expressions +themselves still follow Perl syntax and semantics. The POSIX API is restricted, +and does not give full access to all of PCRE2's facilities. + +The header file for the POSIX-style functions is called pcre2posix.h. The +official POSIX name is regex.h, but I did not want to risk possible problems +with existing files of that name by distributing it that way. To use PCRE2 with +an existing program that uses the POSIX API, pcre2posix.h will have to be +renamed or pointed at by a link (or the program modified, of course). See the +pcre2posix documentation for more details. + + +Documentation for PCRE2 +----------------------- + +If you install PCRE2 in the normal way on a Unix-like system, you will end up +with a set of man pages whose names all start with "pcre2". The one that is +just called "pcre2" lists all the others. In addition to these man pages, the +PCRE2 documentation is supplied in two other forms: + + 1. There are files called doc/pcre2.txt, doc/pcre2grep.txt, and + doc/pcre2test.txt in the source distribution. The first of these is a + concatenation of the text forms of all the section 3 man pages except the + listing of pcre2demo.c and those that summarize individual functions. The + other two are the text forms of the section 1 man pages for the pcre2grep + and pcre2test commands. These text forms are provided for ease of scanning + with text editors or similar tools. They are installed in + /share/doc/pcre2, where is the installation prefix + (defaulting to /usr/local). + + 2. A set of files containing all the documentation in HTML form, hyperlinked + in various ways, and rooted in a file called index.html, is distributed in + doc/html and installed in /share/doc/pcre2/html. + + +Building PCRE2 on non-Unix-like systems +--------------------------------------- + +For a non-Unix-like system, please read the file NON-AUTOTOOLS-BUILD, though if +your system supports the use of "configure" and "make" you may be able to build +PCRE2 using autotools in the same way as for many Unix-like systems. + +PCRE2 can also be configured using CMake, which can be run in various ways +(command line, GUI, etc). This creates Makefiles, solution files, etc. The file +NON-AUTOTOOLS-BUILD has information about CMake. + +PCRE2 has been compiled on many different operating systems. It should be +straightforward to build PCRE2 on any system that has a Standard C compiler and +library, because it uses only Standard C functions. + + +Building PCRE2 without using autotools +-------------------------------------- + +The use of autotools (in particular, libtool) is problematic in some +environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD +file for ways of building PCRE2 without using autotools. + + +Building PCRE2 using autotools +------------------------------ + +The following instructions assume the use of the widely used "configure; make; +make install" (autotools) process. + +If you have downloaded and unpacked a PCRE2 release tarball, run the +"configure" command from the PCRE2 directory, with your current directory set +to the directory where you want the files to be created. This command is a +standard GNU "autoconf" configuration script, for which generic instructions +are supplied in the file INSTALL. + +The files in the GitHub repository do not contain "configure". If you have +downloaded the PCRE2 source files from GitHub, before you can run "configure" +you must run the shell script called autogen.sh. This runs a number of +autotools to create a "configure" script (you must of course have the autotools +commands installed in order to do this). + +Most commonly, people build PCRE2 within its own distribution directory, and in +this case, on many systems, just running "./configure" is sufficient. However, +the usual methods of changing standard defaults are available. For example: + +CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local + +This command specifies that the C compiler should be run with the flags '-O2 +-Wall' instead of the default, and that "make install" should install PCRE2 +under /opt/local instead of the default /usr/local. + +If you want to build in a different directory, just run "configure" with that +directory as current. For example, suppose you have unpacked the PCRE2 source +into /source/pcre2/pcre2-xxx, but you want to build it in +/build/pcre2/pcre2-xxx: + +cd /build/pcre2/pcre2-xxx +/source/pcre2/pcre2-xxx/configure + +PCRE2 is written in C and is normally compiled as a C library. However, it is +possible to build it as a C++ library, though the provided building apparatus +does not have any features to support this. + +There are some optional features that can be included or omitted from the PCRE2 +library. They are also documented in the pcre2build man page. + +. By default, both shared and static libraries are built. You can change this + by adding one of these options to the "configure" command: + + --disable-shared + --disable-static + + Setting --disable-shared ensures that PCRE2 libraries are built as static + libraries. The binaries that are then created as part of the build process + (for example, pcre2test and pcre2grep) are linked statically with one or more + PCRE2 libraries, but may also be dynamically linked with other libraries such + as libc. If you want these binaries to be fully statically linked, you can + set LDFLAGS like this: + + LDFLAGS=--static ./configure --disable-shared + + Note the two hyphens in --static. Of course, this works only if static + versions of all the relevant libraries are available for linking. See also + "Shared libraries" below. + +. By default, only the 8-bit library is built. If you add --enable-pcre2-16 to + the "configure" command, the 16-bit library is also built. If you add + --enable-pcre2-32 to the "configure" command, the 32-bit library is also + built. If you want only the 16-bit or 32-bit library, use --disable-pcre2-8 + to disable building the 8-bit library. + +. If you want to include support for just-in-time (JIT) compiling, which can + give large performance improvements on certain platforms, add --enable-jit to + the "configure" command. This support is available only for certain hardware + architectures. If you try to enable it on an unsupported architecture, there + will be a compile time error. If in doubt, use --enable-jit=auto, which + enables JIT only if the current hardware is supported. + +. If you are enabling JIT under SELinux environment you may also want to add + --enable-jit-sealloc, which enables the use of an executable memory allocator + that is compatible with SELinux. Warning: this allocator is experimental! + It does not support fork() operation and may crash when no disk space is + available. This option has no effect if JIT is disabled. + +. If you do not want to make use of the default support for UTF-8 Unicode + character strings in the 8-bit library, UTF-16 Unicode character strings in + the 16-bit library, or UTF-32 Unicode character strings in the 32-bit + library, you can add --disable-unicode to the "configure" command. This + reduces the size of the libraries. It is not possible to configure one + library with Unicode support, and another without, in the same configuration. + It is also not possible to use --enable-ebcdic (see below) with Unicode + support, so if this option is set, you must also use --disable-unicode. + + When Unicode support is available, the use of a UTF encoding still has to be + enabled by setting the PCRE2_UTF option at run time or starting a pattern + with (*UTF). When PCRE2 is compiled with Unicode support, its input can only + either be ASCII or UTF-8/16/32, even when running on EBCDIC platforms. + + As well as supporting UTF strings, Unicode support includes support for the + \P, \p, and \X sequences that recognize Unicode character properties. + However, only a subset of Unicode properties are supported; see the + pcre2pattern man page for details. Escape sequences such as \d and \w in + patterns do not by default make use of Unicode properties, but can be made to + do so by setting the PCRE2_UCP option or starting a pattern with (*UCP). + +. You can build PCRE2 to recognize either CR or LF or the sequence CRLF, or any + of the preceding, or any of the Unicode newline sequences, or the NUL (zero) + character as indicating the end of a line. Whatever you specify at build time + is the default; the caller of PCRE2 can change the selection at run time. The + default newline indicator is a single LF character (the Unix standard). You + can specify the default newline indicator by adding --enable-newline-is-cr, + --enable-newline-is-lf, --enable-newline-is-crlf, + --enable-newline-is-anycrlf, --enable-newline-is-any, or + --enable-newline-is-nul to the "configure" command, respectively. + +. By default, the sequence \R in a pattern matches any Unicode line ending + sequence. This is independent of the option specifying what PCRE2 considers + to be the end of a line (see above). However, the caller of PCRE2 can + restrict \R to match only CR, LF, or CRLF. You can make this the default by + adding --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R"). + +. In a pattern, the escape sequence \C matches a single code unit, even in a + UTF mode. This can be dangerous because it breaks up multi-code-unit + characters. You can build PCRE2 with the use of \C permanently locked out by + adding --enable-never-backslash-C (note the upper case C) to the "configure" + command. When \C is allowed by the library, individual applications can lock + it out by calling pcre2_compile() with the PCRE2_NEVER_BACKSLASH_C option. + +. PCRE2 has a counter that limits the depth of nesting of parentheses in a + pattern. This limits the amount of system stack that a pattern uses when it + is compiled. The default is 250, but you can change it by setting, for + example, + + --with-parens-nest-limit=500 + +. PCRE2 has a counter that can be set to limit the amount of computing resource + it uses when matching a pattern. If the limit is exceeded during a match, the + match fails. The default is ten million. You can change the default by + setting, for example, + + --with-match-limit=500000 + + on the "configure" command. This is just the default; individual calls to + pcre2_match() or pcre2_dfa_match() can supply their own value. There is more + discussion in the pcre2api man page (search for pcre2_set_match_limit). + +. There is a separate counter that limits the depth of nested backtracking + (pcre2_match()) or nested function calls (pcre2_dfa_match()) during a + matching process, which indirectly limits the amount of heap memory that is + used, and in the case of pcre2_dfa_match() the amount of stack as well. This + counter also has a default of ten million, which is essentially "unlimited". + You can change the default by setting, for example, + + --with-match-limit-depth=5000 + + There is more discussion in the pcre2api man page (search for + pcre2_set_depth_limit). + +. You can also set an explicit limit on the amount of heap memory used by + the pcre2_match() and pcre2_dfa_match() interpreters: + + --with-heap-limit=500 + + The units are kibibytes (units of 1024 bytes). This limit does not apply when + the JIT optimization (which has its own memory control features) is used. + There is more discussion on the pcre2api man page (search for + pcre2_set_heap_limit). + +. In the 8-bit library, the default maximum compiled pattern size is around + 64 kibibytes. You can increase this by adding --with-link-size=3 to the + "configure" command. PCRE2 then uses three bytes instead of two for offsets + to different parts of the compiled pattern. In the 16-bit library, + --with-link-size=3 is the same as --with-link-size=4, which (in both + libraries) uses four-byte offsets. Increasing the internal link size reduces + performance in the 8-bit and 16-bit libraries. In the 32-bit library, the + link size setting is ignored, as 4-byte offsets are always used. + +. Lookbehind assertions in which one or more branches can match a variable + number of characters are supported only if there is a maximum matching length + for each top-level branch. There is a limit to this maximum that defaults to + 255 characters. You can alter this default by a setting such as + + --with-max-varlookbehind=100 + + The limit can be changed at runtime by calling pcre2_set_max_varlookbehind(). + Lookbehind assertions in which every branch matches a fixed number of + characters (not necessarily all the same) are not constrained by this limit. + +. For speed, PCRE2 uses four tables for manipulating and identifying characters + whose code point values are less than 256. By default, it uses a set of + tables for ASCII encoding that is part of the distribution. If you specify + + --enable-rebuild-chartables + + a program called pcre2_dftables is compiled and run in the default C locale + when you obey "make". It builds a source file called pcre2_chartables.c. If + you do not specify this option, pcre2_chartables.c is created as a copy of + pcre2_chartables.c.dist. See "Character tables" below for further + information. + +. It is possible to compile PCRE2 for use on systems that use EBCDIC as their + character code (as opposed to ASCII/Unicode) by specifying + + --enable-ebcdic --disable-unicode + + This automatically implies --enable-rebuild-chartables (see above). However, + when PCRE2 is built this way, it always operates in EBCDIC. It cannot support + both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25, + which specifies that the code value for the EBCDIC NL character is 0x25 + instead of the default 0x15. + +. If you specify --enable-debug, additional debugging code is included in the + build. This option is intended for use by the PCRE2 maintainers. + +. In environments where valgrind is installed, if you specify + + --enable-valgrind + + PCRE2 will use valgrind annotations to mark certain memory regions as + unaddressable. This allows it to detect invalid memory accesses, and is + mostly useful for debugging PCRE2 itself. + +. In environments where the gcc compiler is used and lcov is installed, if you + specify + + --enable-coverage + + the build process implements a code coverage report for the test suite. The + report is generated by running "make coverage". If ccache is installed on + your system, it must be disabled when building PCRE2 for coverage reporting. + You can do this by setting the environment variable CCACHE_DISABLE=1 before + running "make" to build PCRE2. There is more information about coverage + reporting in the "pcre2build" documentation. + +. When JIT support is enabled, pcre2grep automatically makes use of it, unless + you add --disable-pcre2grep-jit to the "configure" command. + +. There is support for calling external programs during matching in the + pcre2grep command, using PCRE2's callout facility with string arguments. This + support can be disabled by adding --disable-pcre2grep-callout to the + "configure" command. There are two kinds of callout: one that generates + output from inbuilt code, and another that calls an external program. The + latter has special support for Windows and VMS; otherwise it assumes the + existence of the fork() function. This facility can be disabled by adding + --disable-pcre2grep-callout-fork to the "configure" command. + +. The pcre2grep program currently supports only 8-bit data files, and so + requires the 8-bit PCRE2 library. It is possible to compile pcre2grep to use + libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by + specifying one or both of + + --enable-pcre2grep-libz + --enable-pcre2grep-libbz2 + + Of course, the relevant libraries must be installed on your system. + +. The default starting size (in bytes) of the internal buffer used by pcre2grep + can be set by, for example: + + --with-pcre2grep-bufsize=51200 + + The value must be a plain integer. The default is 20480. The amount of memory + used by pcre2grep is actually three times this number, to allow for "before" + and "after" lines. If very long lines are encountered, the buffer is + automatically enlarged, up to a fixed maximum size. + +. The default maximum size of pcre2grep's internal buffer can be set by, for + example: + + --with-pcre2grep-max-bufsize=2097152 + + The default is either 1048576 or the value of --with-pcre2grep-bufsize, + whichever is the larger. + +. It is possible to compile pcre2test so that it links with the libreadline + or libedit libraries, by specifying, respectively, + + --enable-pcre2test-libreadline or --enable-pcre2test-libedit + + If this is done, when pcre2test's input is from a terminal, it reads it using + the readline() function. This provides line-editing and history facilities. + Note that libreadline is GPL-licenced, so if you distribute a binary of + pcre2test linked in this way, there may be licensing issues. These can be + avoided by linking with libedit (which has a BSD licence) instead. + + Enabling libreadline causes the -lreadline option to be added to the + pcre2test build. In many operating environments with a system-installed + readline library this is sufficient. However, in some environments (e.g. if + an unmodified distribution version of readline is in use), it may be + necessary to specify something like LIBS="-lncurses" as well. This is + because, to quote the readline INSTALL, "Readline uses the termcap functions, + but does not link with the termcap or curses library itself, allowing + applications which link with readline the option to choose an appropriate + library." If you get error messages about missing functions tgetstr, tgetent, + tputs, tgetflag, or tgoto, this is the problem, and linking with the ncurses + library should fix it. + +. The C99 standard defines formatting modifiers z and t for size_t and + ptrdiff_t values, respectively. By default, PCRE2 uses these modifiers in + environments other than Microsoft Visual Studio versions earlier than 2013 + when __STDC_VERSION__ is defined and has a value greater than or equal to + 199901L (indicating C99). However, there is at least one environment that + claims to be C99 but does not support these modifiers. If + --disable-percent-zt is specified, no use is made of the z or t modifiers. + Instead of %td or %zu, %lu is used, with a cast for size_t values. + +. There is a special option called --enable-fuzz-support for use by people who + want to run fuzzing tests on PCRE2. At present this applies only to the 8-bit + library. If set, it causes an extra library called libpcre2-fuzzsupport.a to + be built, but not installed. This contains a single function called + LLVMFuzzerTestOneInput() whose arguments are a pointer to a string and the + length of the string. When called, this function tries to compile the string + as a pattern, and if that succeeds, to match it. This is done both with no + options and with some random options bits that are generated from the string. + Setting --enable-fuzz-support also causes a binary called pcre2fuzzcheck to + be created. This is normally run under valgrind or used when PCRE2 is + compiled with address sanitizing enabled. It calls the fuzzing function and + outputs information about what it is doing. The input strings are specified + by arguments: if an argument starts with "=" the rest of it is a literal + input string. Otherwise, it is assumed to be a file name, and the contents + of the file are the test string. + +. Releases before 10.30 could be compiled with --disable-stack-for-recursion, + which caused pcre2_match() to use individual blocks on the heap for + backtracking instead of recursive function calls (which use the stack). This + is now obsolete because pcre2_match() was refactored always to use the heap + (in a much more efficient way than before). This option is retained for + backwards compatibility, but has no effect other than to output a warning. + +The "configure" script builds the following files for the basic C library: + +. Makefile the makefile that builds the library +. src/config.h build-time configuration options for the library +. src/pcre2.h the public PCRE2 header file +. pcre2-config script that shows the building settings such as CFLAGS + that were set for "configure" +. libpcre2-8.pc ) +. libpcre2-16.pc ) data for the pkg-config command +. libpcre2-32.pc ) +. libpcre2-posix.pc ) +. libtool script that builds shared and/or static libraries + +Versions of config.h and pcre2.h are distributed in the src directory of PCRE2 +tarballs under the names config.h.generic and pcre2.h.generic. These are +provided for those who have to build PCRE2 without using "configure" or CMake. +If you use "configure" or CMake, the .generic versions are not used. + +The "configure" script also creates config.status, which is an executable +script that can be run to recreate the configuration, and config.log, which +contains compiler output from tests that "configure" runs. + +Once "configure" has run, you can run "make". This builds whichever of the +libraries libpcre2-8, libpcre2-16 and libpcre2-32 are configured, and a test +program called pcre2test. If you enabled JIT support with --enable-jit, another +test program called pcre2_jit_test is built as well. If the 8-bit library is +built, libpcre2-posix, pcre2posix_test, and the pcre2grep command are also +built. Running "make" with the -j option may speed up compilation on +multiprocessor systems. + +The command "make check" runs all the appropriate tests. Details of the PCRE2 +tests are given below in a separate section of this document. The -j option of +"make" can also be used when running the tests. + +You can use "make install" to install PCRE2 into live directories on your +system. The following are installed (file names are all relative to the + that is set when "configure" is run): + + Commands (bin): + pcre2test + pcre2grep (if 8-bit support is enabled) + pcre2-config + + Libraries (lib): + libpcre2-8 (if 8-bit support is enabled) + libpcre2-16 (if 16-bit support is enabled) + libpcre2-32 (if 32-bit support is enabled) + libpcre2-posix (if 8-bit support is enabled) + + Configuration information (lib/pkgconfig): + libpcre2-8.pc + libpcre2-16.pc + libpcre2-32.pc + libpcre2-posix.pc + + Header files (include): + pcre2.h + pcre2posix.h + + Man pages (share/man/man{1,3}): + pcre2grep.1 + pcre2test.1 + pcre2-config.1 + pcre2.3 + pcre2*.3 (lots more pages, all starting "pcre2") + + HTML documentation (share/doc/pcre2/html): + index.html + *.html (lots more pages, hyperlinked from index.html) + + Text file documentation (share/doc/pcre2): + AUTHORS + COPYING + ChangeLog + LICENCE + NEWS + README + pcre2.txt (a concatenation of the man(3) pages) + pcre2test.txt the pcre2test man page + pcre2grep.txt the pcre2grep man page + pcre2-config.txt the pcre2-config man page + +If you want to remove PCRE2 from your system, you can run "make uninstall". +This removes all the files that "make install" installed. However, it does not +remove any directories, because these are often shared with other programs. + + +Retrieving configuration information +------------------------------------ + +Running "make install" installs the command pcre2-config, which can be used to +recall information about the PCRE2 configuration and installation. For example: + + pcre2-config --version + +prints the version number, and + + pcre2-config --libs8 + +outputs information about where the 8-bit library is installed. This command +can be included in makefiles for programs that use PCRE2, saving the programmer +from having to remember too many details. Run pcre2-config with no arguments to +obtain a list of possible arguments. + +The pkg-config command is another system for saving and retrieving information +about installed libraries. Instead of separate commands for each library, a +single command is used. For example: + + pkg-config --libs libpcre2-16 + +The data is held in *.pc files that are installed in a directory called +/lib/pkgconfig. + + +Shared libraries +---------------- + +The default distribution builds PCRE2 as shared libraries and static libraries, +as long as the operating system supports shared libraries. Shared library +support relies on the "libtool" script which is built as part of the +"configure" process. + +The libtool script is used to compile and link both shared and static +libraries. They are placed in a subdirectory called .libs when they are newly +built. The programs pcre2test and pcre2grep are built to use these uninstalled +libraries (by means of wrapper scripts in the case of shared libraries). When +you use "make install" to install shared libraries, pcre2grep and pcre2test are +automatically re-built to use the newly installed shared libraries before being +installed themselves. However, the versions left in the build directory still +use the uninstalled libraries. + +To build PCRE2 using static libraries only you must use --disable-shared when +configuring it. For example: + +./configure --prefix=/usr/gnu --disable-shared + +Then run "make" in the usual way. Similarly, you can use --disable-static to +build only shared libraries. Note, however, that when you build only static +libraries, binary programs such as pcre2test and pcre2grep may still be +dynamically linked with other libraries (for example, libc) unless you set +LDFLAGS to --static when running "configure". + + +Cross-compiling using autotools +------------------------------- + +You can specify CC and CFLAGS in the normal way to the "configure" command, in +order to cross-compile PCRE2 for some other host. However, you should NOT +specify --enable-rebuild-chartables, because if you do, the pcre2_dftables.c +source file is compiled and run on the local host, in order to generate the +inbuilt character tables (the pcre2_chartables.c file). This will probably not +work, because pcre2_dftables.c needs to be compiled with the local compiler, +not the cross compiler. + +When --enable-rebuild-chartables is not specified, pcre2_chartables.c is +created by making a copy of pcre2_chartables.c.dist, which is a default set of +tables that assumes ASCII code. Cross-compiling with the default tables should +not be a problem. + +If you need to modify the character tables when cross-compiling, you should +move pcre2_chartables.c.dist out of the way, then compile pcre2_dftables.c by +hand and run it on the local host to make a new version of +pcre2_chartables.c.dist. See the pcre2build section "Creating character tables +at build time" for more details. + + +Making new tarballs +------------------- + +The command "make dist" creates three PCRE2 tarballs, in tar.gz, tar.bz2, and +zip formats. The command "make distcheck" does the same, but then does a trial +build of the new distribution to ensure that it works. + +If you have modified any of the man page sources in the doc directory, you +should first run the PrepareRelease script before making a distribution. This +script creates the .txt and HTML forms of the documentation from the man pages. + + +Testing PCRE2 +------------- + +To test the basic PCRE2 library on a Unix-like system, run the RunTest script. +There is another script called RunGrepTest that tests the pcre2grep command. +When the 8-bit library is built, a test program for the POSIX wrapper, called +pcre2posix_test, is compiled, and when JIT support is enabled, a test program +called pcre2_jit_test is built. The scripts and the program tests are all run +when you obey "make check". For other environments, see the instructions in +NON-AUTOTOOLS-BUILD. + +The RunTest script runs the pcre2test test program (which is documented in its +own man page) on each of the relevant testinput files in the testdata +directory, and compares the output with the contents of the corresponding +testoutput files. RunTest uses a file called testtry to hold the main output +from pcre2test. Other files whose names begin with "test" are used as working +files in some tests. + +Some tests are relevant only when certain build-time options were selected. For +example, the tests for UTF-8/16/32 features are run only when Unicode support +is available. RunTest outputs a comment when it skips a test. + +Many (but not all) of the tests that are not skipped are run twice if JIT +support is available. On the second run, JIT compilation is forced. This +testing can be suppressed by putting "-nojit" on the RunTest command line. + +The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit +libraries that are enabled. If you want to run just one set of tests, call +RunTest with either the -8, -16 or -32 option. + +If valgrind is installed, you can run the tests under it by putting "-valgrind" +on the RunTest command line. To run pcre2test on just one or more specific test +files, give their numbers as arguments to RunTest, for example: + + RunTest 2 7 11 + +You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the +end), or a number preceded by ~ to exclude a test. For example: + + Runtest 3-15 ~10 + +This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests +except test 13. Whatever order the arguments are in, the tests are always run +in numerical order. + +You can also call RunTest with the single argument "list" to cause it to output +a list of tests. + +The test sequence starts with "test 0", which is a special test that has no +input file, and whose output is not checked. This is because it will be +different on different hardware and with different configurations. The test +exists in order to exercise some of pcre2test's code that would not otherwise +be run. + +Tests 1 and 2 can always be run, as they expect only plain text strings (not +UTF) and make no use of Unicode properties. The first test file can be fed +directly into the perltest.sh script to check that Perl gives the same results. +The only difference you should see is in the first few lines, where the Perl +version is given instead of the PCRE2 version. The second set of tests check +auxiliary functions, error detection, and run-time flags that are specific to +PCRE2. It also uses the debugging flags to check some of the internals of +pcre2_compile(). + +If you build PCRE2 with a locale setting that is not the standard C locale, the +character tables may be different (see next paragraph). In some cases, this may +cause failures in the second set of tests. For example, in a locale where the +isprint() function yields TRUE for characters in the range 128-255, the use of +[:isascii:] inside a character class defines a different set of characters, and +this shows up in this test as a difference in the compiled code, which is being +listed for checking. For example, where the comparison test output contains +[\x00-\x7f] the test might contain [\x00-\xff], and similarly in some other +cases. This is not a bug in PCRE2. + +Test 3 checks pcre2_maketables(), the facility for building a set of character +tables for a specific locale and using them instead of the default tables. The +script uses the "locale" command to check for the availability of the "fr_FR", +"french", or "fr" locale, and uses the first one that it finds. If the "locale" +command fails, or if its output doesn't include "fr_FR", "french", or "fr" in +the list of available locales, the third test cannot be run, and a comment is +output to say why. If running this test produces an error like this: + + ** Failed to set locale "fr_FR" + +it means that the given locale is not available on your system, despite being +listed by "locale". This does not mean that PCRE2 is broken. There are three +alternative output files for the third test, because three different versions +of the French locale have been encountered. The test passes if its output +matches any one of them. + +Tests 4 and 5 check UTF and Unicode property support, test 4 being compatible +with the perltest.sh script, and test 5 checking PCRE2-specific things. + +Tests 6 and 7 check the pcre2_dfa_match() alternative matching function, in +non-UTF mode and UTF-mode with Unicode property support, respectively. + +Test 8 checks some internal offsets and code size features, but it is run only +when Unicode support is enabled. The output is different in 8-bit, 16-bit, and +32-bit modes and for different link sizes, so there are different output files +for each mode and link size. + +Tests 9 and 10 are run only in 8-bit mode, and tests 11 and 12 are run only in +16-bit and 32-bit modes. These are tests that generate different output in +8-bit mode. Each pair are for general cases and Unicode support, respectively. + +Test 13 checks the handling of non-UTF characters greater than 255 by +pcre2_dfa_match() in 16-bit and 32-bit modes. + +Test 14 contains some special UTF and UCP tests that give different output for +different code unit widths. + +Test 15 contains a number of tests that must not be run with JIT. They check, +among other non-JIT things, the match-limiting features of the interpretive +matcher. + +Test 16 is run only when JIT support is not available. It checks that an +attempt to use JIT has the expected behaviour. + +Test 17 is run only when JIT support is available. It checks JIT complete and +partial modes, match-limiting under JIT, and other JIT-specific features. + +Tests 18 and 19 are run only in 8-bit mode. They check the POSIX interface to +the 8-bit library, without and with Unicode support, respectively. + +Test 20 checks the serialization functions by writing a set of compiled +patterns to a file, and then reloading and checking them. + +Tests 21 and 22 test \C support when the use of \C is not locked out, without +and with UTF support, respectively. Test 23 tests \C when it is locked out. + +Tests 24 and 25 test the experimental pattern conversion functions, without and +with UTF support, respectively. + +Test 26 checks Unicode property support using tests that are generated +automatically from the Unicode data tables. + + +Character tables +---------------- + +For speed, PCRE2 uses four tables for manipulating and identifying characters +whose code point values are less than 256. By default, a set of tables that is +built into the library is used. The pcre2_maketables() function can be called +by an application to create a new set of tables in the current locale. This are +passed to PCRE2 by calling pcre2_set_character_tables() to put a pointer into a +compile context. + +The source file called pcre2_chartables.c contains the default set of tables. +By default, this is created as a copy of pcre2_chartables.c.dist, which +contains tables for ASCII coding. However, if --enable-rebuild-chartables is +specified for ./configure, a new version of pcre2_chartables.c is built by the +program pcre2_dftables (compiled from pcre2_dftables.c), which uses the ANSI C +character handling functions such as isalnum(), isalpha(), isupper(), +islower(), etc. to build the table sources. This means that the default C +locale that is set for your system will control the contents of these default +tables. You can change the default tables by editing pcre2_chartables.c and +then re-building PCRE2. If you do this, you should take care to ensure that the +file does not get automatically re-generated. The best way to do this is to +move pcre2_chartables.c.dist out of the way and replace it with your customized +tables. + +When the pcre2_dftables program is run as a result of specifying +--enable-rebuild-chartables, it uses the default C locale that is set on your +system. It does not pay attention to the LC_xxx environment variables. In other +words, it uses the system's default locale rather than whatever the compiling +user happens to have set. If you really do want to build a source set of +character tables in a locale that is specified by the LC_xxx variables, you can +run the pcre2_dftables program by hand with the -L option. For example: + + ./pcre2_dftables -L pcre2_chartables.c.special + +The second argument names the file where the source code for the tables is +written. The first two 256-byte tables provide lower casing and case flipping +functions, respectively. The next table consists of a number of 32-byte bit +maps which identify certain character classes such as digits, "word" +characters, white space, etc. These are used when building 32-byte bit maps +that represent character classes for code points less than 256. The final +256-byte table has bits indicating various character types, as follows: + + 1 white space character + 2 letter + 4 lower case letter + 8 decimal digit + 16 alphanumeric or '_' + +You can also specify -b (with or without -L) when running pcre2_dftables. This +causes the tables to be written in binary instead of as source code. A set of +binary tables can be loaded into memory by an application and passed to +pcre2_compile() in the same way as tables created dynamically by calling +pcre2_maketables(). The tables are just a string of bytes, independent of +hardware characteristics such as endianness. This means they can be bundled +with an application that runs in different environments, to ensure consistent +behaviour. + +See also the pcre2build section "Creating character tables at build time".

+
INTRODUCTION
+

+PCRE2 is the name used for a revised API for the PCRE library, which is a set +of functions, written in C, that implement regular expression pattern matching +using the same syntax and semantics as Perl, with just a few differences. After +nearly two decades, the limitations of the original API were making development +increasingly difficult. The new API is more extensible, and it was simplified +by abolishing the separate "study" optimizing function; in PCRE2, patterns are +automatically optimized where possible. Since forking from PCRE1, the code has +been extensively refactored and new features introduced. The old library is now +obsolete and is no longer maintained. +

+

+As well as Perl-style regular expression patterns, some features that appeared +in Python and the original PCRE before they appeared in Perl are available +using the Python syntax. There is also some support for one or two .NET and +Oniguruma syntax items, and there are options for requesting some minor changes +that give better ECMAScript (aka JavaScript) compatibility. +

+

+The source code for PCRE2 can be compiled to support strings of 8-bit, 16-bit, +or 32-bit code units, which means that up to three separate libraries may be +installed, one for each code unit size. The size of code unit is not related to +the bit size of the underlying hardware. In a 64-bit environment that also +supports 32-bit applications, versions of PCRE2 that are compiled in both +64-bit and 32-bit modes may be needed. +

+

+The original work to extend PCRE to 16-bit and 32-bit code units was done by +Zoltan Herczeg and Christian Persch, respectively. In all three cases, strings +can be interpreted either as one character per code unit, or as UTF-encoded +Unicode, with support for Unicode general category properties. Unicode support +is optional at build time (but is the default). However, processing strings as +UTF code units must be enabled explicitly at run time. The version of Unicode +in use can be discovered by running +

+  pcre2test -C
+
+

+

+The three libraries contain identical sets of functions, with names ending in +_8, _16, or _32, respectively (for example, pcre2_compile_8()). However, +by defining PCRE2_CODE_UNIT_WIDTH to be 8, 16, or 32, a program that uses just +one code unit width can be written using generic names such as +pcre2_compile(), and the documentation is written assuming that this is +the case. +

+

+In addition to the Perl-compatible matching function, PCRE2 contains an +alternative function that matches the same compiled patterns in a different +way. In certain circumstances, the alternative function has some advantages. +For a discussion of the two matching algorithms, see the +pcre2matching +page. +

+

+Details of exactly which Perl regular expression features are and are not +supported by PCRE2 are given in separate documents. See the +pcre2pattern +and +pcre2compat +pages. There is a syntax summary in the +pcre2syntax +page. +

+

+Some features of PCRE2 can be included, excluded, or changed when the library +is built. The +pcre2_config() +function makes it possible for a client to discover which features are +available. The features themselves are described in the +pcre2build +page. Documentation about building PCRE2 for various operating systems can be +found in the +README +and +NON-AUTOTOOLS_BUILD +files in the source distribution. +

+

+The libraries contains a number of undocumented internal functions and data +tables that are used by more than one of the exported external functions, but +which are not intended for use by external callers. Their names all begin with +"_pcre2", which hopefully will not provoke any name clashes. In some +environments, it is possible to control which external symbols are exported +when a shared library is built, and in these cases the undocumented symbols are +not exported. +

+
SECURITY CONSIDERATIONS
+

+If you are using PCRE2 in a non-UTF application that permits users to supply +arbitrary patterns for compilation, you should be aware of a feature that +allows users to turn on UTF support from within a pattern. For example, an +8-bit pattern that begins with "(*UTF)" turns on UTF-8 mode, which interprets +patterns and subjects as strings of UTF-8 code units instead of individual +8-bit characters. This causes both the pattern and any data against which it is +matched to be checked for UTF-8 validity. If the data string is very long, such +a check might use sufficiently many resources as to cause your application to +lose performance. +

+

+One way of guarding against this possibility is to use the +pcre2_pattern_info() function to check the compiled pattern's options for +PCRE2_UTF. Alternatively, you can set the PCRE2_NEVER_UTF option when calling +pcre2_compile(). This causes a compile time error if the pattern contains +a UTF-setting sequence. +

+

+The use of Unicode properties for character types such as \d can also be +enabled from within the pattern, by specifying "(*UCP)". This feature can be +disallowed by setting the PCRE2_NEVER_UCP option. +

+

+If your application is one that supports UTF, be aware that validity checking +can take time. If the same data string is to be matched many times, you can use +the PCRE2_NO_UTF_CHECK option for the second and subsequent matches to avoid +running redundant checks. +

+

+The use of the \C escape sequence in a UTF-8 or UTF-16 pattern can lead to +problems, because it may leave the current matching point in the middle of a +multi-code-unit character. The PCRE2_NEVER_BACKSLASH_C option can be used by an +application to lock out the use of \C, causing a compile-time error if it is +encountered. It is also possible to build PCRE2 with the use of \C permanently +disabled. +

+

+Another way that performance can be hit is by running a pattern that has a very +large search tree against a string that will never match. Nested unlimited +repeats in a pattern are a common example. PCRE2 provides some protection +against this: see the pcre2_set_match_limit() function in the +pcre2api +page. There is a similar function called pcre2_set_depth_limit() that can +be used to restrict the amount of memory that is used. +

+
USER DOCUMENTATION
+

+The user documentation for PCRE2 comprises a number of different sections. In +the "man" format, each of these is a separate "man page". In the HTML format, +each is a separate page, linked from the index page. In the plain text format, +the descriptions of the pcre2grep and pcre2test programs are in +files called pcre2grep.txt and pcre2test.txt, respectively. The +remaining sections, except for the pcre2demo section (which is a program +listing), and the short pages for individual functions, are concatenated in +pcre2.txt, for ease of searching.

+
+DESCRIPTION +
+

+This function scans a compiled regular expression and calls the callback() +function for each callout within the pattern. The yield of the function is zero +for success and non-zero otherwise. The arguments are: +

+  code           Points to the compiled pattern
+  callback       The callback function
+  callout_data   User data that is passed to the callback
+
+The callback() function is passed a pointer to a data block containing +the following fields (not necessarily in this order): +
+  uint32_t   version                Block version number
+  uint32_t   callout_number         Number for numbered callouts
+  PCRE2_SIZE pattern_position       Offset to next item in pattern
+  PCRE2_SIZE next_item_length       Length of next item in pattern
+  PCRE2_SIZE callout_string_offset  Offset to string within pattern
+  PCRE2_SIZE callout_string_length  Length of callout string
+  PCRE2_SPTR callout_string         Points to callout string or is NULL
+
+The second argument passed to the callback() function is the callout data +that was passed to pcre2_callout_enumerate(). The callback() +function must return zero for success. Any other value causes the pattern scan +to stop, with the value being passed back as the result of +pcre2_callout_enumerate(). +

+
+DESCRIPTION +
+

+This function compiles a regular expression pattern into an internal form. Its +arguments are: +

+  What \R matches (Unicode newlines, or CR, LF, CRLF only);
+  PCRE2's character tables;
+  The newline character sequence;
+  The compile time nested parentheses limit;
+  The maximum pattern length (in code units) that is allowed;
+  The additional options bits.
+
+The primary option bits are: +
+  PCRE2_ANCHORED           Force pattern anchoring
+  PCRE2_ALLOW_EMPTY_CLASS  Allow empty classes
+  PCRE2_ALT_BSUX           Alternative handling of \u, \U, and \x
+  PCRE2_ALT_CIRCUMFLEX     Alternative handling of ^ in multiline mode
+  PCRE2_ALT_VERBNAMES      Process backslashes in verb names
+  PCRE2_AUTO_CALLOUT       Compile automatic callouts
+  PCRE2_CASELESS           Do caseless matching
+  PCRE2_DOLLAR_ENDONLY     $ not to match newline at end
+  PCRE2_DOTALL             . matches anything including NL
+  PCRE2_DUPNAMES           Allow duplicate names for subpatterns
+  PCRE2_ENDANCHORED        Pattern can match only at end of subject
+  PCRE2_EXTENDED           Ignore white space and # comments
+  PCRE2_FIRSTLINE          Force matching to be before newline
+  PCRE2_LITERAL            Pattern characters are all literal
+  PCRE2_MATCH_INVALID_UTF  Enable support for matching invalid UTF
+  PCRE2_MATCH_UNSET_BACKREF  Match unset backreferences
+  PCRE2_MULTILINE          ^ and $ match newlines within data
+  PCRE2_NEVER_BACKSLASH_C  Lock out the use of \C in patterns
+  PCRE2_NEVER_UCP          Lock out PCRE2_UCP, e.g. via (*UCP)
+  PCRE2_NEVER_UTF          Lock out PCRE2_UTF, e.g. via (*UTF)

+  PCRE2_NO_START_OPTIMIZE  Disable match-time start optimizations
+  PCRE2_NO_UTF_CHECK       Do not check the pattern for UTF validity
+                             (only relevant if PCRE2_UTF is set)
+  PCRE2_UCP                Use Unicode properties for \d, \w, etc.
+  PCRE2_UNGREEDY           Invert greediness of quantifiers
+  PCRE2_USE_OFFSET_LIMIT   Enable offset limit for unanchored matching
+  PCRE2_UTF                Treat pattern and subjects as UTF strings
+
+PCRE2 must be built with Unicode support (the default) in order to use +PCRE2_UTF, PCRE2_UCP and related options. +

+

+Additional options may be set in the compile context via the +pcre2_set_compile_extra_options +function. +

+

+If either of errorcode or erroroffset is NULL, the function returns +NULL immediately. Otherwise, the yield of this function is a pointer to a +private data structure that contains the compiled pattern, or NULL if an error +was detected. In the error case, a text error message can be obtained by +passing the value returned via the errorcode argument to the +pcre2_get_error_message() function. The offset (in code units) where the +error was encountered is returned via the erroroffset argument. +

+

+If there is no error, the value passed via errorcode returns the message +"no error" if passed to pcre2_get_error_message(), and the value passed +via erroroffset is zero. +

+DESCRIPTION +
+

+This function makes it possible for a client program to find out which optional +features are available in the version of the PCRE2 library it is using. The +arguments are as follows: +

+  what     A code specifying what information is required
+  where    Points to where to put the information
+
+If where is NULL, the function returns the amount of memory needed for +the requested information. When the information is a string, the value is in +code units; for other types of data it is in bytes. +

+

+If where is not NULL, for PCRE2_CONFIG_JITTARGET, +PCRE2_CONFIG_UNICODE_VERSION, and PCRE2_CONFIG_VERSION it must point to a +buffer that is large enough to hold the string. For all other codes it must +point to a uint32_t integer variable. The available codes are: +

+  PCRE2_CONFIG_BSR             Indicates what \R matches by default:
+                                 PCRE2_BSR_UNICODE

+  PCRE2_CONFIG_JITTARGET       Information (a string) about the target architecture for the JIT compiler
+  PCRE2_CONFIG_LINKSIZE        Configured internal link size (2, 3, 4)
+  PCRE2_CONFIG_MATCHLIMIT      Default internal resource limit
+  PCRE2_CONFIG_NEVER_BACKSLASH_C  Whether or not \C is disabled
+  PCRE2_CONFIG_NEWLINE         Code for the default newline sequence:
+                                 PCRE2_NEWLINE_CR
+                                 PCRE2_NEWLINE_LF

+  PCRE2_CONFIG_VERSION         The PCRE2 version (a string)
+
+The function yields a non-negative value on success or the negative value +PCRE2_ERROR_BADOPTION otherwise. This is also the result for the +PCRE2_CONFIG_JITTARGET code if JIT support is not available. When a string is +requested, the function returns the number of code units used, including the +terminating zero. +

+SYNOPSIS +

+

+int pcre2_dfa_match(const pcre2_code *code, PCRE2_SPTR subject, + PCRE2_SIZE length, PCRE2_SIZE startoffset, + uint32_t options, pcre2_match_data *match_data, + pcre2_match_context *mcontext, + int *workspace, PCRE2_SIZE wscount); +

+
+DESCRIPTION +
+

+This function matches a compiled regular expression against a given subject +string, using an alternative matching algorithm that scans the subject string +just once (except when processing lookaround assertions). This function is +not Perl-compatible (the Perl-compatible matching function is +pcre2_match()). The arguments for this function are: +

+  code         Points to the compiled pattern
+  subject      Points to the subject string
+  length       Length of the subject string
+  startoffset  Offset in the subject at which to start matching
+  options      Option bits
+  match_data   Points to a match data block, for results
+  mcontext     Points to a match context, or is NULL
+  workspace    Points to a vector of ints used as working space
+  wscount      Number of elements in the vector
+
+The size of output vector needed to contain all the results depends on the +number of simultaneous matches, not on the number of parentheses in the +pattern. Using pcre2_match_data_create_from_pattern() to create the match +data block is therefore not advisable when using this function. +

+

+A match context is needed only if you want to set up a callout function or +specify the heap limit or the match or the recursion depth limits. The +length and startoffset values are code units, not characters. The +options are: +

+  PCRE2_ANCHORED          Match only at the first position
+  PCRE2_COPY_MATCHED_SUBJECT
+                          On success, make a private subject copy
+  PCRE2_ENDANCHORED       Pattern can match only at end of subject
+  PCRE2_NOTBOL            Subject is not the beginning of a line
+  PCRE2_NOTEOL            Subject is not the end of a line
+  PCRE2_NOTEMPTY          An empty string is not a valid match
+  PCRE2_NOTEMPTY_ATSTART  An empty string at the start of the subject is not a valid match
+  PCRE2_NO_UTF_CHECK      Do not check the subject for UTF validity (only relevant if PCRE2_UTF
+                           was set at compile time)
+  PCRE2_PARTIAL_HARD      Return PCRE2_ERROR_PARTIAL for a partial match even if there is a full match
+  PCRE2_PARTIAL_SOFT      Return PCRE2_ERROR_PARTIAL for a partial match if no full matches are found
+  PCRE2_DFA_RESTART       Restart after a partial match
+  PCRE2_DFA_SHORTEST      Return only the shortest match
+
+There are restrictions on what may appear in a pattern when using this matching +function. Details are given in the +pcre2matching +documentation. For details of partial matching, see the +pcre2partial +page.

+

+The first argument is a pointer that was returned by a successful call to +pcre2_compile(), and the second must contain one or more of the following +bits: +

+
+There is also an obsolete option called PCRE2_JIT_INVALID_UTF, which has been +superseded by the pcre2_compile() option PCRE2_MATCH_INVALID_UTF. The old +option is deprecated and may be removed in the future. +

+

+The yield of the function is 0 for success, or a negative error code otherwise. +In particular, PCRE2_ERROR_JIT_BADOPTION is returned if JIT is not supported or +if an unknown bit is set in options. The function can also return +PCRE2_ERROR_NOMEMORY if JIT is unable to allocate executable memory for the +compiler, even if it was because of a system security restriction. +

+
+DESCRIPTION +
+

+This function matches a compiled regular expression that has been successfully +processed by the JIT compiler against a given subject string, using a matching +algorithm that is similar to Perl's. It is a "fast path" interface to JIT, and +it bypasses some of the sanity checks that pcre2_match() applies. +

+

+In UTF mode, the subject string is not checked for UTF validity. Unless +PCRE2_MATCH_INVALID_UTF was set when the pattern was compiled, passing an +invalid UTF string results in undefined behaviour. Your program may crash or +loop or give wrong results. In the absence of PCRE2_MATCH_INVALID_UTF you +should only call pcre2_jit_match() in UTF mode if you are sure the +subject is valid. +

+

+The arguments for pcre2_jit_match() are exactly the same as for +pcre2_match(), +except that the subject string must be specified with a length; +PCRE2_ZERO_TERMINATED is not supported. +

+

+The supported options are PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY, +PCRE2_NOTEMPTY_ATSTART, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. Unsupported +options are ignored. +

+

+The return values are the same as for pcre2_match() plus +PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial or complete) is requested +that was not compiled. For details of partial matching, see the +pcre2partial +page. +

+void pcre2_jit_stack_assign(pcre2_match_context *mcontext, + pcre2_jit_callback callback_function, void *callback_data); +

+
+DESCRIPTION +
+

+This function provides control over the memory used by JIT as a run-time stack +when pcre2_match() or pcre2_jit_match() is called with a pattern +that has been successfully processed by the JIT compiler. The information that +determines which stack is used is put into a match context that is subsequently +passed to a matching function. The arguments of this function are: +

+  mcontext       a pointer to a match context
+  callback       a callback function
+  callback_data  a JIT stack or a value to be passed to the callback
+
+

+

+If mcontext is NULL, the function returns immediately, without doing +anything. +

+

+If callback is NULL and callback_data is NULL, an internal 32KiB +block on the machine stack is used. +

+

+If callback is NULL and callback_data is not NULL, +callback_data must be a valid JIT stack, the result of calling +pcre2_jit_stack_create(). +

+

+If callback not NULL, it is called with callback_data as an +argument at the start of matching, in order to set up a JIT stack. If the +result is NULL, the internal 32KiB stack is used; otherwise the return value +must be a valid JIT stack, the result of calling +pcre2_jit_stack_create(). +

+

+You may safely use the same JIT stack for multiple patterns, as long as they +are all matched in the same thread. In a multithread application, each thread +must use its own JIT stack. For more details, see the +pcre2jit +page. +

+
+DESCRIPTION +
+

+This function is used to create a stack for use by the code compiled by the JIT +compiler. The first two arguments are a starting size for the stack, and a +maximum size to which it is allowed to grow. The final argument is a general +context, for memory allocation functions, or NULL for standard memory +allocation. The result can be passed to the JIT run-time code by calling +pcre2_jit_stack_assign() to associate the stack with a compiled pattern, +which can then be processed by pcre2_match() or pcre2_jit_match(). +A maximum stack size of 512KiB to 1MiB should be more than enough for any +pattern. If the stack couldn't be allocated or the values passed were not +reasonable, NULL will be returned. For more details, see the +pcre2jit +page. +

+
+DESCRIPTION +
+

+This function matches a compiled regular expression against a given subject +string, using a matching algorithm that is similar to Perl's. It returns +offsets to what it has matched and to captured substrings via the +match_data block, which can be processed by functions with names that +start with pcre2_get_ovector_...() or pcre2_substring_...(). The +return from pcre2_match() is one more than the highest numbered capturing +pair that has been set (for example, 1 if there are no captures), zero if the +vector of offsets is too small, or a negative error code for no match and other +errors. The function arguments are: +

+  code         Points to the compiled pattern
+  subject      Points to the subject string
+  length       Length of the subject string
+  startoffset  Offset in the subject at which to start matching
+  options      Option bits
+  match_data   Points to a match data block, for results
+  mcontext     Points to a match context, or is NULL
+
+A match context is needed only if you want to: +
+  Set up a callout function
+  Set a matching offset limit
+  Change the heap memory limit
+  Change the backtracking match limit
+  Change the backtracking depth limit
+  Set custom memory management specifically for the match
+
+The length and startoffset values are code units, not characters. +The length may be given as PCRE2_ZERO_TERMINATED for a subject that is +terminated by a binary zero code unit. The options are: +
+  PCRE2_ANCHORED          Match only at the first position
+  PCRE2_COPY_MATCHED_SUBJECT
+                          On success, make a private subject copy
+  PCRE2_DISABLE_RECURSELOOP_CHECK
+                          Only useful in rare cases; use with care
+  PCRE2_ENDANCHORED       Pattern can match only at end of subject
+  PCRE2_NOTBOL            Subject string is not the beginning of a line
+  PCRE2_NOTEOL            Subject string is not the end of a line
+  PCRE2_NOTEMPTY          An empty string is not a valid match
+  PCRE2_NOTEMPTY_ATSTART  An empty string at the start of the subject is not a valid match
+  PCRE2_NO_JIT            Do not use JIT matching
+  PCRE2_NO_UTF_CHECK      Do not check the subject for UTF validity (only relevant if PCRE2_UTF
+                           was set at compile time)
+  PCRE2_PARTIAL_HARD      Return PCRE2_ERROR_PARTIAL for a partial match even if there is a full match

+DESCRIPTION +
+

+This function creates a new match data block, which is used for holding the +result of a match. The first argument specifies the number of pairs of offsets +that are required. These form the "output vector" (ovector) within the match +data block, and are used to identify the matched string and any captured +substrings when matching with pcre2_match(), or a number of different +matches at the same point when used with pcre2_dfa_match(). There is +always one pair of offsets; if ovecsize is zero, it is treated as one. +

+DESCRIPTION +
+

+This function creates a new match data block for holding the result of a match. +The first argument points to a compiled pattern. The number of capturing +parentheses within the pattern is used to compute the number of pairs of +offsets that are required in the match data block. These form the "output +vector" (ovector) within the match data block, and are used to identify the +matched string and any captured substrings when matching with +pcre2_match(). If you are using pcre2_dfa_match(), which uses the +output vector in a different way, you should use pcre2_match_data_create() +instead of this function. +

+

+The second argument points to a general context, for custom memory management, +or is NULL to use the same memory allocator as was used for the compiled +pattern. The result of the function is NULL if the memory for the block could +not be obtained. +

+
+DESCRIPTION +
+

+This function is part of an experimental set of pattern conversion functions. +It converts a foreign pattern (for example, a glob) into a PCRE2 regular +expression pattern. Its arguments are: +

+  pattern     The foreign pattern
+  length      The length of the input pattern or PCRE2_ZERO_TERMINATED
+  options     Option bits
+  buffer      Pointer to pointer to output buffer, or NULL
+  blength     Pointer to output length field
+  cvcontext   Pointer to a convert context or NULL
+
+The length of the converted pattern (excluding the terminating zero) is +returned via blength. If buffer is NULL, the function just returns +the output length. If buffer points to a NULL pointer, heap memory is +obtained for the converted pattern, using the allocator in the context if +present (or else malloc()), and the field pointed to by buffer is +updated. If buffer points to a non-NULL field, that must point to a +buffer whose size is in the variable pointed to by blength. This value is +updated. +

+

+The option bits are: +

+  PCRE2_CONVERT_UTF                     Input is UTF
+  PCRE2_CONVERT_NO_UTF_CHECK            Do not check UTF validity
+  PCRE2_CONVERT_POSIX_BASIC             Convert POSIX basic pattern
+  PCRE2_CONVERT_POSIX_EXTENDED          Convert POSIX extended pattern
+  PCRE2_CONVERT_GLOB                    ) Convert
+  PCRE2_CONVERT_GLOB_NO_WILD_SEPARATOR  )   various types
+  PCRE2_CONVERT_GLOB_NO_STARSTAR        )     of glob
+
+The return value from pcre2_pattern_convert() is zero on success or a +non-zero PCRE2 error code. +

+

+The pattern conversion functions are described in the +pcre2convert +documentation. +

+
+DESCRIPTION +
+

+This function decodes a serialized set of compiled patterns back into a list of +individual patterns. This is possible only on a host that is running the same +version of PCRE2, with the same code unit width, and the host must also have +the same endianness, pointer width and PCRE2_SIZE type. The arguments for +pcre2_serialize_decode() are: +

+  codes            pointer to a vector in which to build the list
+  number_of_codes  number of slots in the vector
+  bytes            the serialized byte stream
+  gcontext         pointer to a general context or NULL
+
+The bytes argument must point to a block of data that was originally +created by pcre2_serialize_encode(), though it may have been saved on +disc or elsewhere in the meantime. If there are more codes in the serialized +data than slots in the list, only those compiled patterns that will fit are +decoded. The yield of the function is the number of decoded patterns, or one of +the following negative error codes: +
+  PCRE2_ERROR_BADDATA   number_of_codes is zero or less
+  PCRE2_ERROR_BADMAGIC  mismatch of id bytes in bytes
+  PCRE2_ERROR_BADMODE   mismatch of variable unit size or PCRE version
+  PCRE2_ERROR_NOMEMORY  memory allocation failed
+  PCRE2_ERROR_NULL      codes or bytes is NULL
+
+PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled +on a system with different endianness. +

+
+DESCRIPTION +
+

+This function encodes a list of compiled patterns into a byte stream that can +be saved on disc or elsewhere. Note that this is not an abstract format like +Java or .NET. Conversion of the byte stream back into usable compiled patterns +can only happen on a host that is running the same version of PCRE2, with the +same code unit width, and the host must also have the same endianness, pointer +width and PCRE2_SIZE type. The arguments for pcre2_serialize_encode() +are: +

+  codes             pointer to a vector containing the list
+  number_of_codes   number of slots in the vector
+  serialized_bytes  set to point to the serialized byte stream
+  serialized_size   set to the number of bytes in the byte stream
+  gcontext          pointer to a general context or NULL
+
+The context argument is used to obtain memory for the byte stream. When the +serialized data is no longer needed, it must be freed by calling +pcre2_serialize_free(). The yield of the function is the number of +serialized patterns, or one of the following negative error codes: +
+  PCRE2_ERROR_BADDATA      number_of_codes is zero or less
+  PCRE2_ERROR_BADMAGIC     mismatch of id bytes in one of the patterns
+  PCRE2_ERROR_MEMORY       memory allocation failed
+  PCRE2_ERROR_MIXEDTABLES  the patterns do not all use the same tables
+  PCRE2_ERROR_NULL         an argument other than gcontext is NULL
+
+PCRE2_ERROR_BADMAGIC means either that a pattern's code has been corrupted, or +that a slot in the vector does not point to a compiled pattern. +

+  subject       Points to the subject string
+  length        Length of the subject string
+  startoffset   Offset in the subject at which to start matching
+  options       Option bits
+  match_data    Points to a match data block, or is NULL
+  mcontext      Points to a match context, or is NULL
+  replacement   Points to the replacement string
+  rlength       Length of the replacement string
+  outputbuffer  Points to the output buffer
+  outlengthptr  Points to the length of the output buffer
+
+A match data block is needed only if you want to inspect the data from the +final match that is returned in that block or if PCRE2_SUBSTITUTE_MATCHED is +set. A match context is needed only if you want to: +
+  Set up a callout function
+  Set a matching offset limit
+  Change the backtracking match limit
+  Change the backtracking depth limit
+  Set custom memory management in the match context
+
+The length, startoffset and rlength values are code units, +not characters, as is the contents of the variable pointed at by +outlengthptr. This variable must contain the length of the output buffer +when the function is called. If the function is successful, the value is +changed to the length of the new string, excluding the trailing zero that is +automatically added. +

+

+The subject and replacement lengths can be given as PCRE2_ZERO_TERMINATED for +zero-terminated strings. The options are: +

+  PCRE2_ANCHORED                     Match only at the first position
+  PCRE2_ENDANCHORED                  Match only at end of subject
+  PCRE2_NOTBOL                       Subject is not the beginning of a line
+  PCRE2_NOTEOL                       Subject is not the end of a line
+  PCRE2_NOTEMPTY                     An empty string is not a valid match
+  PCRE2_NOTEMPTY_ATSTART             An empty string at the start of the subject is not a valid match
+  PCRE2_NO_JIT                       Do not use JIT matching
+  PCRE2_NO_UTF_CHECK                 Do not check for UTF validity in the subject or replacement
+                                      (only relevant if PCRE2_UTF was set at compile time)
+  PCRE2_SUBSTITUTE_EXTENDED          Do extended replacement processing
+  PCRE2_SUBSTITUTE_GLOBAL            Replace all occurrences in the subject
+  PCRE2_SUBSTITUTE_LITERAL           The replacement string is literal
+  PCRE2_SUBSTITUTE_MATCHED           Use pre-existing match data for first match
+  PCRE2_SUBSTITUTE_OVERFLOW_LENGTH   If overflow, compute needed length
+  PCRE2_SUBSTITUTE_REPLACEMENT_ONLY  Return only replacement string(s)
+  PCRE2_SUBSTITUTE_UNKNOWN_UNSET     Treat unknown group as unset
+  PCRE2_SUBSTITUTE_UNSET_EMPTY       Simple unset insert = empty string
+
+If PCRE2_SUBSTITUTE_LITERAL is set, PCRE2_SUBSTITUTE_EXTENDED, +PCRE2_SUBSTITUTE_UNKNOWN_UNSET, and PCRE2_SUBSTITUTE_UNSET_EMPTY are ignored. +

+

+If PCRE2_SUBSTITUTE_MATCHED is set, match_data must be non-NULL; its +contents must be the result of a call to pcre2_match() using the same +pattern and subject. +

+

+The function returns the number of substitutions, which may be zero if there +are no matches. The result may be greater than one only when +PCRE2_SUBSTITUTE_GLOBAL is set. In the event of an error, a negative error code +is returned. +

+This is a convenience function for extracting all the captured substrings after +a pattern match. It builds a list of pointers to the strings, and (optionally) +a second list that contains their lengths (in code units), excluding a +terminating zero that is added to each of them.

+  match_data    The match data block
+  listptr       Where to put a pointer to the list
+  lengthsptr    Where to put a pointer to the lengths, or NULL
+
+A pointer to a list of pointers is put in the variable whose address is in +listptr. The list is terminated by a NULL pointer. If lengthsptr is +not NULL, a matching list of lengths is created, and its address is placed in +lengthsptr. The yield of the function is zero on success or +PCRE2_ERROR_NOMEMORY if sufficient memory could not be obtained. +

+
PCRE2 8-BIT, 16-BIT, AND 32-BIT LIBRARIES
+

+There are three PCRE2 libraries, supporting 8-bit, 16-bit, and 32-bit code +units, respectively. However, there is just one header file, pcre2.h. +This contains the function prototypes and other definitions for all three +libraries. One, two, or all three can be installed simultaneously. On Unix-like +systems the libraries are called libpcre2-8, libpcre2-16, and +libpcre2-32, and they can also co-exist with the original PCRE libraries. +Every PCRE2 function comes in three different forms, one for each library, for +example: +

+  pcre2_compile_8()
+  pcre2_compile_16()
+  pcre2_compile_32()
+
+There are also three different sets of data types: +
+  PCRE2_UCHAR8, PCRE2_UCHAR16, PCRE2_UCHAR32
+  PCRE2_SPTR8,  PCRE2_SPTR16,  PCRE2_SPTR32
+
+The UCHAR types define unsigned code units of the appropriate widths. +For example, PCRE2_UCHAR16 is usually defined as `uint16_t'. +The SPTR types are pointers to constants of the equivalent UCHAR types, +that is, they are pointers to vectors of unsigned code units. +

+

+Character strings are passed to a PCRE2 library as sequences of unsigned +integers in code units of the appropriate width. The length of a string may +be given as a number of code units, or the string may be specified as +zero-terminated. +

+

+Many applications use only one code unit width. For their convenience, macros +are defined whose names are the generic forms such as pcre2_compile() and +PCRE2_SPTR. These macros use the value of the macro PCRE2_CODE_UNIT_WIDTH to +generate the appropriate width-specific function and macro names. +PCRE2_CODE_UNIT_WIDTH is not defined by default. An application must define it +to be 8, 16, or 32 before including pcre2.h in order to make use of the +generic names. +

+

+Applications that use more than one code unit width can be linked with more +than one PCRE2 library, but must define PCRE2_CODE_UNIT_WIDTH to be 0 before +including pcre2.h, and then use the real function names. Any code that is +to be included in an environment where the value of PCRE2_CODE_UNIT_WIDTH is +unknown should also use the real function names. (Unfortunately, it is not +possible in C code to save and restore the value of a macro.) +

+

+If PCRE2_CODE_UNIT_WIDTH is not defined before including pcre2.h, a +compiler error occurs. +

+

+When using multiple libraries in an application, you must take care when +processing any particular pattern to use only functions from a single library. +For example, if you want to run a match using a pattern that was compiled with +pcre2_compile_16(), you must do so with pcre2_match_16(), not +pcre2_match_8() or pcre2_match_32(). +

+

+In the function summaries above, and in the rest of this document and other +PCRE2 documents, functions and data types are described using their generic +names, without the _8, _16, or _32 suffix. +

+
PCRE2 API OVERVIEW
+

+PCRE2 has its own native API, which is described in this document. There are +also some wrapper functions for the 8-bit library that correspond to the +POSIX regular expression API, but they do not give access to all the +functionality of PCRE2 and they are not thread-safe. They are described in the +pcre2posix +documentation. Both these APIs define a set of C function calls. +

+

+The native API C data types, function prototypes, option values, and error +codes are defined in the header file pcre2.h, which also contains +definitions of PCRE2_MAJOR and PCRE2_MINOR, the major and minor release numbers +for the library. Applications can use these to include support for different +releases of PCRE2. +

+

+In a Windows environment, if you want to statically link an application program +against a non-dll PCRE2 library, you must define PCRE2_STATIC before including +pcre2.h. +

+

+The functions pcre2_compile() and pcre2_match() are used for +compiling and matching regular expressions in a Perl-compatible manner. A +sample program that demonstrates the simplest way of using them is provided in +the file called pcre2demo.c in the PCRE2 source distribution. A listing +of this program is given in the +pcre2demo +documentation, and the +pcre2sample +documentation describes how to compile and run it. +

+

+The compiling and matching functions recognize various options that are passed +as bits in an options argument. There are also some more complicated parameters +such as custom memory management functions and resource limits that are passed +in "contexts" (which are just memory blocks, described below). Simple +applications do not need to make use of contexts. +

+

+Just-in-time (JIT) compiler support is an optional feature of PCRE2 that can be +built in appropriate hardware environments. It greatly speeds up the matching +performance of many patterns. Programs can request that it be used if +available by calling pcre2_jit_compile() after a pattern has been +successfully compiled by pcre2_compile(). This does nothing if JIT +support is not available. +

+

+More complicated programs might need to make use of the specialist functions +pcre2_jit_stack_create(), pcre2_jit_stack_free(), and +pcre2_jit_stack_assign() in order to control the JIT code's memory usage. +

+

+JIT matching is automatically used by pcre2_match() if it is available, +unless the PCRE2_NO_JIT option is set. There is also a direct interface for JIT +matching, which gives improved performance at the expense of less sanity +checking. The JIT-specific functions are discussed in the +pcre2jit +documentation. +

+

+A second matching function, pcre2_dfa_match(), which is not +Perl-compatible, is also provided. This uses a different algorithm for the +matching. The alternative algorithm finds all possible matches (at a given +point in the subject), and scans the subject just once (unless there are +lookaround assertions). However, this algorithm does not return captured +substrings. A description of the two matching algorithms and their advantages +and disadvantages is given in the +pcre2matching +documentation. There is no JIT support for pcre2_dfa_match(). +

+

+In addition to the main compiling and matching functions, there are convenience +functions for extracting captured substrings from a subject string that has +been matched by pcre2_match(). They are: +

+  pcre2_substring_copy_byname()
+  pcre2_substring_copy_bynumber()
+  pcre2_substring_get_byname()
+  pcre2_substring_get_bynumber()
+  pcre2_substring_list_get()
+  pcre2_substring_length_byname()
+  pcre2_substring_length_bynumber()
+  pcre2_substring_nametable_scan()
+  pcre2_substring_number_from_name()
+
+pcre2_substring_free() and pcre2_substring_list_free() are also +provided, to free memory used for extracted strings. If either of these +functions is called with a NULL argument, the function returns immediately +without doing anything. +

+

+The function pcre2_substitute() can be called to match a pattern and +return a copy of the subject string with substitutions for parts that were +matched. +

+

+Functions whose names begin with pcre2_serialize_ are used for saving +compiled patterns on disc or elsewhere, and reloading them later. +

+

+Finally, there are functions for finding out information about a compiled +pattern (pcre2_pattern_info()) and about the configuration with which +PCRE2 was built (pcre2_config()). +

+

+Functions with names ending with _free() are used for freeing memory +blocks of various sorts. In all cases, if one of these functions is called with +a NULL argument, it does nothing. +

+
STRING LENGTHS AND OFFSETS
+

+The PCRE2 API uses string lengths and offsets into strings of code units in +several places. These values are always of type PCRE2_SIZE, which is an +unsigned integer type, currently always defined as size_t. The largest +value that can be stored in such a type (that is ~(PCRE2_SIZE)0) is reserved +as a special indicator for zero-terminated strings and unset offsets. +Therefore, the longest string that can be handled is one less than this +maximum. Note that string lengths are always given in code units. Only in the +8-bit library is such a length the same as the number of bytes in the string. +

+
NEWLINES
+

+PCRE2 supports five different conventions for indicating line breaks in +strings: a single CR (carriage return) character, a single LF (linefeed) +character, the two-character sequence CRLF, any of the three preceding, or any +Unicode newline sequence. The Unicode newline sequences are the three just +mentioned, plus the single characters VT (vertical tab, U+000B), FF (form feed, +U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and PS +(paragraph separator, U+2029). +

+

+Each of the first three conventions is used by at least one operating system as +its standard newline sequence. When PCRE2 is built, a default can be specified. +If it is not, the default is set to LF, which is the Unix standard. However, +the newline convention can be changed by an application when calling +pcre2_compile(), or it can be specified by special text at the start of +the pattern itself; this overrides any other settings. See the +pcre2pattern +page for details of the special character sequences. +

+

+In the PCRE2 documentation the word "newline" is used to mean "the character or +pair of characters that indicate a line break". The choice of newline +convention affects the handling of the dot, circumflex, and dollar +metacharacters, the handling of #-comments in /x mode, and, when CRLF is a +recognized line ending sequence, the match position advancement for a +non-anchored pattern. There is more detail about this in the +section on pcre2_match() options +below. +

+

+The choice of newline convention does not affect the interpretation of +the \n or \r escape sequences, nor does it affect what \R matches; this has +its own separate convention. +

+
MULTITHREADING
+

+In a multithreaded application it is important to keep thread-specific data +separate from data that can be shared between threads. The PCRE2 library code +itself is thread-safe: it contains no static or global variables. The API is +designed to be fairly simple for non-threaded applications while at the same +time ensuring that multithreaded applications can use it. +

+

+There are several different blocks of data that are used to pass information +between the application and the PCRE2 libraries. +

+
+The compiled pattern +
+

+A pointer to the compiled form of a pattern is returned to the user when +pcre2_compile() is successful. The data in the compiled pattern is fixed, +and does not change when the pattern is matched. Therefore, it is thread-safe, +that is, the same compiled pattern can be used by more than one thread +simultaneously. For example, an application can compile all its patterns at the +start, before forking off multiple threads that use them. However, if the +just-in-time (JIT) optimization feature is being used, it needs separate memory +stack areas for each thread. See the +pcre2jit +documentation for more details. +

+

+In a more complicated situation, where patterns are compiled only when they are +first needed, but are still shared between threads, pointers to compiled +patterns must be protected from simultaneous writing by multiple threads. This +is somewhat tricky to do correctly. If you know that writing to a pointer is +atomic in your environment, you can use logic like this: +

+  Get a read-only (shared) lock (mutex) for pointer
+  if (pointer == NULL)
+    {
+    Get a write (unique) lock for pointer
+    if (pointer == NULL) pointer = pcre2_compile(...
+    }
+  Release the lock
+  Use pointer in pcre2_match()
+
+Of course, testing for compilation errors should also be included in the code. +

+

+The reason for checking the pointer a second time is as follows: Several +threads may have acquired the shared lock and tested the pointer for being +NULL, but only one of them will be given the write lock, with the rest kept +waiting. The winning thread will compile the pattern and store the result. +After this thread releases the write lock, another thread will get it, and if +it does not retest pointer for being NULL, will recompile the pattern and +overwrite the pointer, creating a memory leak and possibly causing other +issues. +

+

+In an environment where writing to a pointer may not be atomic, the above logic +is not sufficient. The thread that is doing the compiling may be descheduled +after writing only part of the pointer, which could cause other threads to use +an invalid value. Instead of checking the pointer itself, a separate "pointer +is valid" flag (that can be updated atomically) must be used: +

+  Get a read-only (shared) lock (mutex) for pointer
+  if (!pointer_is_valid)
+    {
+    Get a write (unique) lock for pointer
+    if (!pointer_is_valid)
+      {
+      pointer = pcre2_compile(...
+      pointer_is_valid = TRUE
+      }
+    }
+  Release the lock
+  Use pointer in pcre2_match()
+
+If JIT is being used, but the JIT compilation is not being done immediately +(perhaps waiting to see if the pattern is used often enough), similar logic is +required. JIT compilation updates a value within the compiled code block, so a +thread must gain unique write access to the pointer before calling +pcre2_jit_compile(). Alternatively, pcre2_code_copy() or +pcre2_code_copy_with_tables() can be used to obtain a private copy of the +compiled code before calling the JIT compiler. +

+
+Context blocks +
+

+The next main section below introduces the idea of "contexts" in which PCRE2 +functions are called. A context is nothing more than a collection of parameters +that control the way PCRE2 operates. Grouping a number of parameters together +in a context is a convenient way of passing them to a PCRE2 function without +using lots of arguments. The parameters that are stored in contexts are in some +sense "advanced features" of the API. Many straightforward applications will +not need to use contexts. +

+

+In a multithreaded application, if the parameters in a context are values that +are never changed, the same context can be used by all the threads. However, if +any thread needs to change any value in a context, it must make its own +thread-specific copy. +

+
+Match blocks +
+

+The matching functions need a block of memory for storing the results of a +match. This includes details of what was matched, as well as additional +information such as the name of a (*MARK) setting. Each thread must provide its +own copy of this memory. +

+
PCRE2 CONTEXTS
+

+Some PCRE2 functions have a lot of parameters, many of which are used only by +specialist applications, for example, those that use custom memory management +or non-standard character tables. To keep function argument lists at a +reasonable size, and at the same time to keep the API extensible, "uncommon" +parameters are passed to certain functions in a context instead of +directly. A context is just a block of memory that holds the parameter values. +Applications that do not need to adjust any of the context parameters can pass +NULL when a context pointer is required. +

+

+There are three different types of context: a general context that is relevant +for several PCRE2 operations, a compile-time context, and a match-time context. +

+
+The general context +
+

+At present, this context just contains pointers to (and data for) external +memory management functions that are called from several places in the PCRE2 +library. The context is named `general' rather than specifically `memory' +because in future other fields may be added. If you do not want to supply your +own custom memory management functions, you do not need to bother with a +general context. A general context is created by: +
+
+pcre2_general_context *pcre2_general_context_create( + void *(*private_malloc)(PCRE2_SIZE, void *), + void (*private_free)(void *, void *), void *memory_data); +
+
+The two function pointers specify custom memory management functions, whose +prototypes are: +

+  void *private_malloc(PCRE2_SIZE, void *);
+  void  private_free(void *, void *);
+
+Whenever code in PCRE2 calls these functions, the final argument is the value +of memory_data. Either of the first two arguments of the creation +function may be NULL, in which case the system memory management functions +malloc() and free() are used. (This is not currently useful, as +there are no other fields in a general context, but in future there might be.) +The private_malloc() function is used (if supplied) to obtain memory for +storing the context, and all three values are saved as part of the context. +

+

+Whenever PCRE2 creates a data block of any kind, the block contains a pointer +to the free() function that matches the malloc() function that was +used. When the time comes to free the block, this function is called. +

+

+A general context can be copied by calling: +
+
+pcre2_general_context *pcre2_general_context_copy( + pcre2_general_context *gcontext); +
+
+The memory used for a general context should be freed by calling: +
+
+void pcre2_general_context_free(pcre2_general_context *gcontext); +
+
+If this function is passed a NULL argument, it returns immediately without +doing anything. +

+
+The compile context +
+

+A compile context is required if you want to provide an external function for +stack checking during compilation or to change the default values of any of the +following compile-time parameters: +

+  What \R matches (Unicode newlines or CR, LF, CRLF only)
+  PCRE2's character tables
+  The newline character sequence
+  The compile time nested parentheses limit
+  The maximum length of the pattern string
+  The extra options bits (none set by default)
+
+A compile context is also required if you are using custom memory management. +If none of these apply, just pass NULL as the context argument of +pcre2_compile(). +

+

+A compile context is created, copied, and freed by the following functions: +
+
+pcre2_compile_context *pcre2_compile_context_create( + pcre2_general_context *gcontext); +
+
+pcre2_compile_context *pcre2_compile_context_copy( + pcre2_compile_context *ccontext); +
+
+void pcre2_compile_context_free(pcre2_compile_context *ccontext); +
+
+A compile context is created with default values for its parameters. These can +be changed by calling the following functions, which return 0 on success, or +PCRE2_ERROR_BADDATA if invalid data is detected. +
+
+int pcre2_set_bsr(pcre2_compile_context *ccontext, + uint32_t value); +
+
+The value must be PCRE2_BSR_ANYCRLF, to specify that \R matches only CR, LF, +or CRLF, or PCRE2_BSR_UNICODE, to specify that \R matches any Unicode line +ending sequence. The value is used by the JIT compiler and by the two +interpreted matching functions, pcre2_match() and +pcre2_dfa_match(). +
+
+int pcre2_set_character_tables(pcre2_compile_context *ccontext, + const uint8_t *tables); +
+
+The value must be the result of a call to pcre2_maketables(), whose only +argument is a general context. This function builds a set of character tables +in the current locale. +
+
+int pcre2_set_compile_extra_options(pcre2_compile_context *ccontext, + uint32_t extra_options); +
+
+As PCRE2 has developed, almost all the 32 option bits that are available in +the options argument of pcre2_compile() have been used up. To avoid +running out, the compile context contains a set of extra option bits which are +used for some newer, assumed rarer, options. This function sets those bits. It +always sets all the bits (either on or off). It does not modify any existing +setting. The available options are defined in the section entitled "Extra +compile options" +below. +
+
+int pcre2_set_max_pattern_length(pcre2_compile_context *ccontext, + PCRE2_SIZE value); +
+
+This sets a maximum length, in code units, for any pattern string that is +compiled with this context. If the pattern is longer, an error is generated. +This facility is provided so that applications that accept patterns from +external sources can limit their size. The default is the largest number that a +PCRE2_SIZE variable can hold, which is effectively unlimited. +
+
+int pcre2_set_max_pattern_compiled_length( + pcre2_compile_context *ccontext, PCRE2_SIZE value); +
+
+This sets a maximum size, in bytes, for the memory needed to hold the compiled +version of a pattern that is compiled with this context. If the pattern needs +more memory, an error is generated. This facility is provided so that +applications that accept patterns from external sources can limit the amount of +memory they use. The default is the largest number that a PCRE2_SIZE variable +can hold, which is effectively unlimited. +
+
+int pcre2_set_max_varlookbehind(pcre2_compile_contest *ccontext, +" uint32_t value); +
+
+This sets a maximum length for the number of characters matched by a +variable-length lookbehind assertion. The default is set when PCRE2 is built, +with the ultimate default being 255, the same as Perl. Lookbehind assertions +without a bounding length are not supported. +
+
+int pcre2_set_newline(pcre2_compile_context *ccontext, + uint32_t value); +
+
+This specifies which characters or character sequences are to be recognized as +newlines. The value must be one of PCRE2_NEWLINE_CR (carriage return only), +PCRE2_NEWLINE_LF (linefeed only), PCRE2_NEWLINE_CRLF (the two-character +sequence CR followed by LF), PCRE2_NEWLINE_ANYCRLF (any of the above), +PCRE2_NEWLINE_ANY (any Unicode newline sequence), or PCRE2_NEWLINE_NUL (the +NUL character, that is a binary zero). +

+

+A pattern can override the value set in the compile context by starting with a +sequence such as (*CRLF). See the +pcre2pattern +page for details. +

+

+When a pattern is compiled with the PCRE2_EXTENDED or PCRE2_EXTENDED_MORE +option, the newline convention affects the recognition of the end of internal +comments starting with #. The value is saved with the compiled pattern for +subsequent use by the JIT compiler and by the two interpreted matching +functions, pcre2_match() and pcre2_dfa_match(). +
+
+int pcre2_set_parens_nest_limit(pcre2_compile_context *ccontext, + uint32_t value); +
+
+This parameter adjusts the limit, set when PCRE2 is built (default 250), on the +depth of parenthesis nesting in a pattern. This limit stops rogue patterns +using up too much system stack when being compiled. The limit applies to +parentheses of all kinds, not just capturing parentheses. +
+
+int pcre2_set_compile_recursion_guard(pcre2_compile_context *ccontext, + int (*guard_function)(uint32_t, void *), void *user_data); +
+
+There is at least one application that runs PCRE2 in threads with very limited +system stack, where running out of stack is to be avoided at all costs. The +parenthesis limit above cannot take account of how much stack is actually +available during compilation. For a finer control, you can supply a function +that is called whenever pcre2_compile() starts to compile a parenthesized +part of a pattern. This function can check the actual stack size (or anything +else that it wants to, of course). +

+

+The first argument to the callout function gives the current depth of +nesting, and the second is user data that is set up by the last argument of +pcre2_set_compile_recursion_guard(). The callout function should return +zero if all is well, or non-zero to force an error. +

+
+The match context +
+

+A match context is required if you want to: +

+  Set up a callout function
+  Set an offset limit for matching an unanchored pattern
+  Change the limit on the amount of heap used when matching
+  Change the backtracking match limit
+  Change the backtracking depth limit
+  Set custom memory management specifically for the match
+
+If none of these apply, just pass NULL as the context argument of +pcre2_match(), pcre2_dfa_match(), or pcre2_jit_match(). +

+

+A match context is created, copied, and freed by the following functions: +
+
+pcre2_match_context *pcre2_match_context_create( + pcre2_general_context *gcontext); +
+
+pcre2_match_context *pcre2_match_context_copy( + pcre2_match_context *mcontext); +
+
+void pcre2_match_context_free(pcre2_match_context *mcontext); +
+
+A match context is created with default values for its parameters. These can +be changed by calling the following functions, which return 0 on success, or +PCRE2_ERROR_BADDATA if invalid data is detected. +
+
+int pcre2_set_callout(pcre2_match_context *mcontext, + int (*callout_function)(pcre2_callout_block *, void *), + void *callout_data); +
+
+This sets up a callout function for PCRE2 to call at specified points +during a matching operation. Details are given in the +pcre2callout +documentation. +
+
+int pcre2_set_substitute_callout(pcre2_match_context *mcontext, + int (*callout_function)(pcre2_substitute_callout_block *, void *), + void *callout_data); +
+
+This sets up a callout function for PCRE2 to call after each substitution +made by pcre2_substitute(). Details are given in the section entitled +"Creating a new string with substitutions" +below. +
+
+int pcre2_set_offset_limit(pcre2_match_context *mcontext, + PCRE2_SIZE value); +
+
+The offset_limit parameter limits how far an unanchored search can +advance in the subject string. The default value is PCRE2_UNSET. The +pcre2_match() and pcre2_dfa_match() functions return +PCRE2_ERROR_NOMATCH if a match with a starting point before or at the given +offset is not found. The pcre2_substitute() function makes no more +substitutions. +

+

+For example, if the pattern /abc/ is matched against "123abc" with an offset +limit less than 3, the result is PCRE2_ERROR_NOMATCH. A match can never be +found if the startoffset argument of pcre2_match(), +pcre2_dfa_match(), or pcre2_substitute() is greater than the offset +limit set in the match context. +

+

+When using this facility, you must set the PCRE2_USE_OFFSET_LIMIT option when +calling pcre2_compile() so that when JIT is in use, different code can be +compiled. If a match is started with a non-default match limit when +PCRE2_USE_OFFSET_LIMIT is not set, an error is generated. +

+

+The offset limit facility can be used to track progress when searching large +subject strings or to limit the extent of global substitutions. See also the +PCRE2_FIRSTLINE option, which requires a match to start before or at the first +newline that follows the start of matching in the subject. If this is set with +an offset limit, a match must occur in the first line and also within the +offset limit. In other words, whichever limit comes first is used. +
+
+int pcre2_set_heap_limit(pcre2_match_context *mcontext, + uint32_t value); +
+
+The heap_limit parameter specifies, in units of kibibytes (1024 bytes), +the maximum amount of heap memory that pcre2_match() may use to hold +backtracking information when running an interpretive match. This limit also +applies to pcre2_dfa_match(), which may use the heap when processing +patterns with a lot of nested pattern recursion or lookarounds or atomic +groups. This limit does not apply to matching with the JIT optimization, which +has its own memory control arrangements (see the +pcre2jit +documentation for more details). If the limit is reached, the negative error +code PCRE2_ERROR_HEAPLIMIT is returned. The default limit can be set when PCRE2 +is built; if it is not, the default is set very large and is essentially +unlimited. +

+

+A value for the heap limit may also be supplied by an item at the start of a +pattern of the form +

+  (*LIMIT_HEAP=ddd)
+
+where ddd is a decimal number. However, such a setting is ignored unless ddd is +less than the limit set by the caller of pcre2_match() or, if no such +limit is set, less than the default. +

+

+The pcre2_match() function always needs some heap memory, so setting a +value of zero guarantees a "heap limit exceeded" error. Details of how +pcre2_match() uses the heap are given in the +pcre2perform +documentation. +

+

+For pcre2_dfa_match(), a vector on the system stack is used when +processing pattern recursions, lookarounds, or atomic groups, and only if this +is not big enough is heap memory used. In this case, setting a value of zero +disables the use of the heap. +
+
+int pcre2_set_match_limit(pcre2_match_context *mcontext, + uint32_t value); +
+
+The match_limit parameter provides a means of preventing PCRE2 from using +up too many computing resources when processing patterns that are not going to +match, but which have a very large number of possibilities in their search +trees. The classic example is a pattern that uses nested unlimited repeats. +

+

+There is an internal counter in pcre2_match() that is incremented each +time round its main matching loop. If this value reaches the match limit, +pcre2_match() returns the negative value PCRE2_ERROR_MATCHLIMIT. This has +the effect of limiting the amount of backtracking that can take place. For +patterns that are not anchored, the count restarts from zero for each position +in the subject string. This limit also applies to pcre2_dfa_match(), +though the counting is done in a different way. +

+

+When pcre2_match() is called with a pattern that was successfully +processed by pcre2_jit_compile(), the way in which matching is executed +is entirely different. However, there is still the possibility of runaway +matching that goes on for a very long time, and so the match_limit value +is also used in this case (but in a different way) to limit how long the +matching can continue. +

+

+The default value for the limit can be set when PCRE2 is built; the default is +10 million, which handles all but the most extreme cases. A value for the match +limit may also be supplied by an item at the start of a pattern of the form +

+  (*LIMIT_MATCH=ddd)
+
+where ddd is a decimal number. However, such a setting is ignored unless ddd is +less than the limit set by the caller of pcre2_match() or +pcre2_dfa_match() or, if no such limit is set, less than the default. +
+
+int pcre2_set_depth_limit(pcre2_match_context *mcontext, + uint32_t value); +
+
+This parameter limits the depth of nested backtracking in pcre2_match(). +Each time a nested backtracking point is passed, a new memory frame is used +to remember the state of matching at that point. Thus, this parameter +indirectly limits the amount of memory that is used in a match. However, +because the size of each memory frame depends on the number of capturing +parentheses, the actual memory limit varies from pattern to pattern. This limit +was more useful in versions before 10.30, where function recursion was used for +backtracking. +

+

+The depth limit is not relevant, and is ignored, when matching is done using +JIT compiled code. However, it is supported by pcre2_dfa_match(), which +uses it to limit the depth of nested internal recursive function calls that +implement atomic groups, lookaround assertions, and pattern recursions. This +limits, indirectly, the amount of system stack that is used. It was more useful +in versions before 10.32, when stack memory was used for local workspace +vectors for recursive function calls. From version 10.32, only local variables +are allocated on the stack and as each call uses only a few hundred bytes, even +a small stack can support quite a lot of recursion. +

+

+If the depth of internal recursive function calls is great enough, local +workspace vectors are allocated on the heap from version 10.32 onwards, so the +depth limit also indirectly limits the amount of heap memory that is used. A +recursive pattern such as /(.(?2))((?1)|)/, when matched to a very long string +using pcre2_dfa_match(), can use a great deal of memory. However, it is +probably better to limit heap usage directly by calling +pcre2_set_heap_limit(). +

+

+The default value for the depth limit can be set when PCRE2 is built; if it is +not, the default is set to the same value as the default for the match limit. +If the limit is exceeded, pcre2_match() or pcre2_dfa_match() +returns PCRE2_ERROR_DEPTHLIMIT. A value for the depth limit may also be +supplied by an item at the start of a pattern of the form +

+  (*LIMIT_DEPTH=ddd)
+
+where ddd is a decimal number. However, such a setting is ignored unless ddd is +less than the limit set by the caller of pcre2_match() or +pcre2_dfa_match() or, if no such limit is set, less than the default. +

+
CHECKING BUILD-TIME OPTIONS
+

+int pcre2_config(uint32_t what, void *where); +

+

+The function pcre2_config() makes it possible for a PCRE2 client to find +the value of certain configuration parameters and to discover which optional +features have been compiled into the PCRE2 library. The +pcre2build +documentation has more details about these features. +

+

+The first argument for pcre2_config() specifies which information is +required. The second argument is a pointer to memory into which the information +is placed. If NULL is passed, the function returns the amount of memory that is +needed for the requested information. For calls that return numerical values, +the value is in bytes; when requesting these values, where should point +to appropriately aligned memory. For calls that return strings, the required +length is given in code units, not counting the terminating zero. +

+

+When requesting information, the returned value from pcre2_config() is +non-negative on success, or the negative error code PCRE2_ERROR_BADOPTION if +the value in the first argument is not recognized. The following information is +available: +

+  PCRE2_CONFIG_BSR
+
+The output is a uint32_t integer whose value indicates what character +sequences the \R escape sequence matches by default. A value of +PCRE2_BSR_UNICODE means that \R matches any Unicode line ending sequence; a +value of PCRE2_BSR_ANYCRLF means that \R matches only CR, LF, or CRLF. The +default can be overridden when a pattern is compiled. +
+  PCRE2_CONFIG_COMPILED_WIDTHS
+
+The output is a uint32_t integer whose lower bits indicate which code unit +widths were selected when PCRE2 was built. The 1-bit indicates 8-bit support, +and the 2-bit and 4-bit indicate 16-bit and 32-bit support, respectively. +
+  PCRE2_CONFIG_DEPTHLIMIT
+
+The output is a uint32_t integer that gives the default limit for the depth of +nested backtracking in pcre2_match() or the depth of nested recursions, +lookarounds, and atomic groups in pcre2_dfa_match(). Further details are +given with pcre2_set_depth_limit() above. +
+  PCRE2_CONFIG_HEAPLIMIT
+
+The output is a uint32_t integer that gives, in kibibytes, the default limit +for the amount of heap memory used by pcre2_match() or +pcre2_dfa_match(). Further details are given with +pcre2_set_heap_limit() above. +
+  PCRE2_CONFIG_JIT
+
+The output is a uint32_t integer that is set to one if support for just-in-time +compiling is included in the library; otherwise it is set to zero. Note that +having the support in the library does not guarantee that JIT will be used for +any given match. See the +pcre2jit +documentation for more details. +
+  PCRE2_CONFIG_JITTARGET
+
+The where argument should point to a buffer that is at least 48 code +units long. (The exact length required can be found by calling +pcre2_config() with where set to NULL.) The buffer is filled with a +string that contains the name of the architecture for which the JIT compiler is +configured, for example "x86 32bit (little endian + unaligned)". If JIT support +is not available, PCRE2_ERROR_BADOPTION is returned, otherwise the number of +code units used is returned. This is the length of the string, plus one unit +for the terminating zero. +
+  PCRE2_CONFIG_LINKSIZE
+
+The output is a uint32_t integer that contains the number of bytes used for +internal linkage in compiled regular expressions. When PCRE2 is configured, the +value can be set to 2, 3, or 4, with the default being 2. This is the value +that is returned by pcre2_config(). However, when the 16-bit library is +compiled, a value of 3 is rounded up to 4, and when the 32-bit library is +compiled, internal linkages always use 4 bytes, so the configured value is not +relevant. +

+

+The default value of 2 for the 8-bit and 16-bit libraries is sufficient for all +but the most massive patterns, since it allows the size of the compiled pattern +to be up to 65535 code units. Larger values allow larger regular expressions to +be compiled by those two libraries, but at the expense of slower matching. +

+  PCRE2_CONFIG_MATCHLIMIT
+
+The output is a uint32_t integer that gives the default match limit for +pcre2_match(). Further details are given with +pcre2_set_match_limit() above. +
+  PCRE2_CONFIG_NEWLINE
+
+The output is a uint32_t integer whose value specifies the default character +sequence that is recognized as meaning "newline". The values are: +
+  PCRE2_NEWLINE_CR       Carriage return (CR)
+  PCRE2_NEWLINE_LF       Linefeed (LF)
+  PCRE2_NEWLINE_CRLF     Carriage return, linefeed (CRLF)
+  PCRE2_NEWLINE_ANY      Any Unicode line ending
+  PCRE2_NEWLINE_ANYCRLF  Any of CR, LF, or CRLF
+  PCRE2_NEWLINE_NUL      The NUL character (binary zero)
+
+The default should normally correspond to the standard sequence for your +operating system. +
+  PCRE2_CONFIG_NEVER_BACKSLASH_C
+
+The output is a uint32_t integer that is set to one if the use of \C was +permanently disabled when PCRE2 was built; otherwise it is set to zero. +
+  PCRE2_CONFIG_PARENSLIMIT
+
+The output is a uint32_t integer that gives the maximum depth of nesting +of parentheses (of any kind) in a pattern. This limit is imposed to cap the +amount of system stack used when a pattern is compiled. It is specified when +PCRE2 is built; the default is 250. This limit does not take into account the +stack that may already be used by the calling application. For finer control +over compilation stack usage, see pcre2_set_compile_recursion_guard(). +
+  PCRE2_CONFIG_STACKRECURSE
+
+This parameter is obsolete and should not be used in new code. The output is a +uint32_t integer that is always set to zero. +
+  PCRE2_CONFIG_TABLES_LENGTH
+
+The output is a uint32_t integer that gives the length of PCRE2's character +processing tables in bytes. For details of these tables see the +section on locale support +below. +
+  PCRE2_CONFIG_UNICODE_VERSION
+
+The where argument should point to a buffer that is at least 24 code +units long. (The exact length required can be found by calling +pcre2_config() with where set to NULL.) If PCRE2 has been compiled +without Unicode support, the buffer is filled with the text "Unicode not +supported". Otherwise, the Unicode version string (for example, "8.0.0") is +inserted. The number of code units used is returned. This is the length of the +string plus one unit for the terminating zero. +
+  PCRE2_CONFIG_UNICODE
+
+The output is a uint32_t integer that is set to one if Unicode support is +available; otherwise it is set to zero. Unicode support implies UTF support. +
+  PCRE2_CONFIG_VERSION
+
+The where argument should point to a buffer that is at least 24 code +units long. (The exact length required can be found by calling +pcre2_config() with where set to NULL.) The buffer is filled with +the PCRE2 version string, zero-terminated. The number of code units used is +returned. This is the length of the string plus one unit for the terminating +zero. +

+
COMPILING A PATTERN
+

+pcre2_code *pcre2_compile(PCRE2_SPTR pattern, PCRE2_SIZE length, + uint32_t options, int *errorcode, PCRE2_SIZE *erroroffset, + pcre2_compile_context *ccontext); +
+
+void pcre2_code_free(pcre2_code *code); +
+
+pcre2_code *pcre2_code_copy(const pcre2_code *code); +
+
+pcre2_code *pcre2_code_copy_with_tables(const pcre2_code *code); +

+

+The pcre2_compile() function compiles a pattern into an internal form. +The pattern is defined by a pointer to a string of code units and a length in +code units. If the pattern is zero-terminated, the length can be specified as +PCRE2_ZERO_TERMINATED. A NULL pattern pointer with a length of zero is treated +as an empty string (NULL with a non-zero length causes an error return). The +function returns a pointer to a block of memory that contains the compiled +pattern and related data, or NULL if an error occurred. +

+

+If the compile context argument ccontext is NULL, memory for the compiled +pattern is obtained by calling malloc(). Otherwise, it is obtained from +the same memory function that was used for the compile context. The caller must +free the memory by calling pcre2_code_free() when it is no longer needed. +If pcre2_code_free() is called with a NULL argument, it returns +immediately, without doing anything. +

+

+The function pcre2_code_copy() makes a copy of the compiled code in new +memory, using the same memory allocator as was used for the original. However, +if the code has been processed by the JIT compiler (see +below), +the JIT information cannot be copied (because it is position-dependent). +The new copy can initially be used only for non-JIT matching, though it can be +passed to pcre2_jit_compile() if required. If pcre2_code_copy() is +called with a NULL argument, it returns NULL. +

+

+The pcre2_code_copy() function provides a way for individual threads in a +multithreaded application to acquire a private copy of shared compiled code. +However, it does not make a copy of the character tables used by the compiled +pattern; the new pattern code points to the same tables as the original code. +(See +"Locale Support" +below for details of these character tables.) In many applications the same +tables are used throughout, so this behaviour is appropriate. Nevertheless, +there are occasions when a copy of a compiled pattern and the relevant tables +are needed. The pcre2_code_copy_with_tables() provides this facility. +Copies of both the code and the tables are made, with the new code pointing to +the new tables. The memory for the new tables is automatically freed when +pcre2_code_free() is called for the new copy of the compiled code. If +pcre2_code_copy_with_tables() is called with a NULL argument, it returns +NULL. +

+

+NOTE: When one of the matching functions is called, pointers to the compiled +pattern and the subject string are set in the match data block so that they can +be referenced by the substring extraction functions after a successful match. +After running a match, you must not free a compiled pattern or a subject string +until after all operations on the +match data block +have taken place, unless, in the case of the subject string, you have used the +PCRE2_COPY_MATCHED_SUBJECT option, which is described in the section entitled +"Option bits for pcre2_match()" +below. +

+

+The options argument for pcre2_compile() contains various bit +settings that affect the compilation. It should be zero if none of them are +required. The available options are described below. Some of them (in +particular, those that are compatible with Perl, but some others as well) can +also be set and unset from within the pattern (see the detailed description in +the +pcre2pattern +documentation). +

+

+For those options that can be different in different parts of the pattern, the +contents of the options argument specifies their settings at the start of +compilation. The PCRE2_ANCHORED, PCRE2_ENDANCHORED, and PCRE2_NO_UTF_CHECK +options can be set at the time of matching as well as at compile time. +

+

+Some additional options and less frequently required compile-time parameters +(for example, the newline setting) can be provided in a compile context (as +described +above). +

+

+If errorcode or erroroffset is NULL, pcre2_compile() returns +NULL immediately. Otherwise, the variables to which these point are set to an +error code and an offset (number of code units) within the pattern, +respectively, when pcre2_compile() returns NULL because a compilation +error has occurred. +

+

+There are nearly 100 positive error codes that pcre2_compile() may return +if it finds an error in the pattern. There are also some negative error codes +that are used for invalid UTF strings when validity checking is in force. These +are the same as given by pcre2_match() and pcre2_dfa_match(), and +are described in the +pcre2unicode +documentation. There is no separate documentation for the positive error codes, +because the textual error messages that are obtained by calling the +pcre2_get_error_message() function (see "Obtaining a textual error +message" +below) +should be self-explanatory. Macro names starting with PCRE2_ERROR_ are defined +for both positive and negative error codes in pcre2.h. When compilation +is successful errorcode is set to a value that returns the message "no +error" if passed to pcre2_get_error_message(). +

+

+The value returned in erroroffset is an indication of where in the +pattern an error occurred. When there is no error, zero is returned. A non-zero +value is not necessarily the furthest point in the pattern that was read. For +example, after the error "lookbehind assertion is not fixed length", the error +offset points to the start of the failing assertion. For an invalid UTF-8 or +UTF-16 string, the offset is that of the first code unit of the failing +character. +

+

+Some errors are not detected until the whole pattern has been scanned; in these +cases, the offset passed back is the length of the pattern. Note that the +offset is in code units, not characters, even in a UTF mode. It may sometimes +point into the middle of a UTF-8 or UTF-16 character. +

+

+This code fragment shows a typical straightforward call to +pcre2_compile(): +

+  pcre2_code *re;
+  PCRE2_SIZE erroffset;
+  int errorcode;
+  re = pcre2_compile(
+    "^A.*Z",                /* the pattern */
+    PCRE2_ZERO_TERMINATED,  /* the pattern is zero-terminated */
+    0,                      /* default options */
+    &errorcode,             /* for error code */
+    &erroffset,             /* for error offset */
+    NULL);                  /* no compile context */
+
+
+

+
+Main compile options +
+

+The following names for option bits are defined in the pcre2.h header +file: +

+  PCRE2_ANCHORED
+
+If this bit is set, the pattern is forced to be "anchored", that is, it is +constrained to match only at the first matching point in the string that is +being searched (the "subject string"). This effect can also be achieved by +appropriate constructs in the pattern itself, which is the only way to do it in +Perl. +
+  PCRE2_ALLOW_EMPTY_CLASS
+
+By default, for compatibility with Perl, a closing square bracket that +immediately follows an opening one is treated as a data character for the +class. When PCRE2_ALLOW_EMPTY_CLASS is set, it terminates the class, which +therefore contains no characters and so can never match. +
+  PCRE2_ALT_BSUX
+
+This option request alternative handling of three escape sequences, which +makes PCRE2's behaviour more like ECMAscript (aka JavaScript). When it is set: +

+

+(1) \U matches an upper case "U" character; by default \U causes a compile +time error (Perl uses \U to upper case subsequent characters). +

+

+(2) \u matches a lower case "u" character unless it is followed by four +hexadecimal digits, in which case the hexadecimal number defines the code point +to match. By default, \u causes a compile time error (Perl uses it to upper +case the following character). +

+

+(3) \x matches a lower case "x" character unless it is followed by two +hexadecimal digits, in which case the hexadecimal number defines the code point +to match. By default, as in Perl, a hexadecimal number is always expected after +\x, but it may have zero, one, or two digits (so, for example, \xz matches a +binary zero character followed by z). +

+

+ECMAscript 6 added additional functionality to \u. This can be accessed using +the PCRE2_EXTRA_ALT_BSUX extra option (see "Extra compile options" +below). +Note that this alternative escape handling applies only to patterns. Neither of +these options affects the processing of replacement strings passed to +pcre2_substitute(). +

+  PCRE2_ALT_CIRCUMFLEX
+
+In multiline mode (when PCRE2_MULTILINE is set), the circumflex metacharacter +matches at the start of the subject (unless PCRE2_NOTBOL is set), and also +after any internal newline. However, it does not match after a newline at the +end of the subject, for compatibility with Perl. If you want a multiline +circumflex also to match after a terminating newline, you must set +PCRE2_ALT_CIRCUMFLEX. +
+  PCRE2_ALT_VERBNAMES
+
+By default, for compatibility with Perl, the name in any verb sequence such as +(*MARK:NAME) is any sequence of characters that does not include a closing +parenthesis. The name is not processed in any way, and it is not possible to +include a closing parenthesis in the name. However, if the PCRE2_ALT_VERBNAMES +option is set, normal backslash processing is applied to verb names and only an +unescaped closing parenthesis terminates the name. A closing parenthesis can be +included in a name either as \) or between \Q and \E. If the PCRE2_EXTENDED +or PCRE2_EXTENDED_MORE option is set with PCRE2_ALT_VERBNAMES, unescaped +whitespace in verb names is skipped and #-comments are recognized, exactly as +in the rest of the pattern. +
+  PCRE2_AUTO_CALLOUT
+
+If this bit is set, pcre2_compile() automatically inserts callout items, +all with number 255, before each pattern item, except immediately before or +after an explicit callout in the pattern. For discussion of the callout +facility, see the +pcre2callout +documentation. +
+  PCRE2_CASELESS
+
+If this bit is set, letters in the pattern match both upper and lower case +letters in the subject. It is equivalent to Perl's /i option, and it can be +changed within a pattern by a (?i) option setting. If either PCRE2_UTF or +PCRE2_UCP is set, Unicode properties are used for all characters with more than +one other case, and for all characters whose code points are greater than +U+007F. Note that there are two ASCII characters, K and S, that, in addition to +their lower case ASCII equivalents, are case-equivalent with U+212A (Kelvin +sign) and U+017F (long S) respectively. If you do not want this case +equivalence, you can suppress it by setting PCRE2_EXTRA_CASELESS_RESTRICT. +

+

+For lower valued characters with only one other case, a lookup table is used +for speed. When neither PCRE2_UTF nor PCRE2_UCP is set, a lookup table is used +for all code points less than 256, and higher code points (available only in +16-bit or 32-bit mode) are treated as not having another case. +

+  PCRE2_DOLLAR_ENDONLY
+
+If this bit is set, a dollar metacharacter in the pattern matches only at the +end of the subject string. Without this option, a dollar also matches +immediately before a newline at the end of the string (but not before any other +newlines). The PCRE2_DOLLAR_ENDONLY option is ignored if PCRE2_MULTILINE is +set. There is no equivalent to this option in Perl, and no way to set it within +a pattern. +
+  PCRE2_DOTALL
+
+If this bit is set, a dot metacharacter in the pattern matches any character, +including one that indicates a newline. However, it only ever matches one +character, even if newlines are coded as CRLF. Without this option, a dot does +not match when the current position in the subject is at a newline. This option +is equivalent to Perl's /s option, and it can be changed within a pattern by a +(?s) option setting. A negative class such as [^a] always matches newline +characters, and the \N escape sequence always matches a non-newline character, +independent of the setting of PCRE2_DOTALL. +
+  PCRE2_DUPNAMES
+
+If this bit is set, names used to identify capture groups need not be unique. +This can be helpful for certain types of pattern when it is known that only one +instance of the named group can ever be matched. There are more details of +named capture groups below; see also the +pcre2pattern +documentation. +
+  PCRE2_ENDANCHORED
+
+If this bit is set, the end of any pattern match must be right at the end of +the string being searched (the "subject string"). If the pattern match +succeeds by reaching (*ACCEPT), but does not reach the end of the subject, the +match fails at the current starting point. For unanchored patterns, a new match +is then tried at the next starting point. However, if the match succeeds by +reaching the end of the pattern, but not the end of the subject, backtracking +occurs and an alternative match may be found. Consider these two patterns: +
+  .(*ACCEPT)|..
+  .|..
+
+If matched against "abc" with PCRE2_ENDANCHORED set, the first matches "c" +whereas the second matches "bc". The effect of PCRE2_ENDANCHORED can also be +achieved by appropriate constructs in the pattern itself, which is the only way +to do it in Perl. +

+

+For DFA matching with pcre2_dfa_match(), PCRE2_ENDANCHORED applies only +to the first (that is, the longest) matched string. Other parallel matches, +which are necessarily substrings of the first one, must obviously end before +the end of the subject. +

+  PCRE2_EXTENDED
+
+If this bit is set, most white space characters in the pattern are totally +ignored except when escaped, inside a character class, or inside a \Q...\E +sequence. However, white space is not allowed within sequences such as (?> that +introduce various parenthesized groups, nor within numerical quantifiers such +as {1,3}. Ignorable white space is permitted between an item and a following +quantifier and between a quantifier and a following + that indicates +possessiveness. PCRE2_EXTENDED is equivalent to Perl's /x option, and it can be +changed within a pattern by a (?x) option setting. +

+

+When PCRE2 is compiled without Unicode support, PCRE2_EXTENDED recognizes as +white space only those characters with code points less than 256 that are +flagged as white space in its low-character table. The table is normally +created by +pcre2_maketables(), +which uses the isspace() function to identify space characters. In most +ASCII environments, the relevant characters are those with code points 0x0009 +(tab), 0x000A (linefeed), 0x000B (vertical tab), 0x000C (formfeed), 0x000D +(carriage return), and 0x0020 (space). +

+

+When PCRE2 is compiled with Unicode support, in addition to these characters, +five more Unicode "Pattern White Space" characters are recognized by +PCRE2_EXTENDED. These are U+0085 (next line), U+200E (left-to-right mark), +U+200F (right-to-left mark), U+2028 (line separator), and U+2029 (paragraph +separator). This set of characters is the same as recognized by Perl's /x +option. Note that the horizontal and vertical space characters that are matched +by the \h and \v escapes in patterns are a much bigger set. +

+

+As well as ignoring most white space, PCRE2_EXTENDED also causes characters +between an unescaped # outside a character class and the next newline, +inclusive, to be ignored, which makes it possible to include comments inside +complicated patterns. Note that the end of this type of comment is a literal +newline sequence in the pattern; escape sequences that happen to represent a +newline do not count. +

+

+Which characters are interpreted as newlines can be specified by a setting in +the compile context that is passed to pcre2_compile() or by a special +sequence at the start of the pattern, as described in the section entitled +"Newline conventions" +in the pcre2pattern documentation. A default is defined when PCRE2 is +built. +

+  PCRE2_EXTENDED_MORE
+
+This option has the effect of PCRE2_EXTENDED, but, in addition, unescaped space +and horizontal tab characters are ignored inside a character class. Note: only +these two characters are ignored, not the full set of pattern white space +characters that are ignored outside a character class. PCRE2_EXTENDED_MORE is +equivalent to Perl's /xx option, and it can be changed within a pattern by a +(?xx) option setting. +
+  PCRE2_FIRSTLINE
+
+If this option is set, the start of an unanchored pattern match must be before +or at the first newline in the subject string following the start of matching, +though the matched text may continue over the newline. If startoffset is +non-zero, the limiting newline is not necessarily the first newline in the +subject. For example, if the subject string is "abc\nxyz" (where \n +represents a single-character newline) a pattern match for "yz" succeeds with +PCRE2_FIRSTLINE if startoffset is greater than 3. See also +PCRE2_USE_OFFSET_LIMIT, which provides a more general limiting facility. If +PCRE2_FIRSTLINE is set with an offset limit, a match must occur in the first +line and also within the offset limit. In other words, whichever limit comes +first is used. This option has no effect for anchored patterns. +
+  PCRE2_LITERAL
+
+If this option is set, all meta-characters in the pattern are disabled, and it +is treated as a literal string. Matching literal strings with a regular +expression engine is not the most efficient way of doing it. If you are doing a +lot of literal matching and are worried about efficiency, you should consider +using other approaches. The only other main options that are allowed with +PCRE2_LITERAL are: PCRE2_ANCHORED, PCRE2_ENDANCHORED, PCRE2_AUTO_CALLOUT, +PCRE2_CASELESS, PCRE2_FIRSTLINE, PCRE2_MATCH_INVALID_UTF, +PCRE2_NO_START_OPTIMIZE, PCRE2_NO_UTF_CHECK, PCRE2_UTF, and +PCRE2_USE_OFFSET_LIMIT. The extra options PCRE2_EXTRA_MATCH_LINE and +PCRE2_EXTRA_MATCH_WORD are also supported. Any other options cause an error. +
+  PCRE2_MATCH_INVALID_UTF
+
+This option forces PCRE2_UTF (see below) and also enables support for matching +by pcre2_match() in subject strings that contain invalid UTF sequences. +Note, however, that the 16-bit and 32-bit PCRE2 libraries process strings as +sequences of uint16_t or uint32_t code points. They cannot find valid UTF +sequences within an arbitrary string of bytes unless such sequences are +suitably aligned. This facility is not supported for DFA matching. For details, +see the +pcre2unicode +documentation. +
+  PCRE2_MATCH_UNSET_BACKREF
+
+If this option is set, a backreference to an unset capture group matches an +empty string (by default this causes the current matching alternative to fail). +A pattern such as (\1)(a) succeeds when this option is set (assuming it can +find an "a" in the subject), whereas it fails by default, for Perl +compatibility. Setting this option makes PCRE2 behave more like ECMAscript (aka +JavaScript). +
+  PCRE2_MULTILINE
+
+By default, for the purposes of matching "start of line" and "end of line", +PCRE2 treats the subject string as consisting of a single line of characters, +even if it actually contains newlines. The "start of line" metacharacter (^) +matches only at the start of the string, and the "end of line" metacharacter +($) matches only at the end of the string, or before a terminating newline +(except when PCRE2_DOLLAR_ENDONLY is set). Note, however, that unless +PCRE2_DOTALL is set, the "any character" metacharacter (.) does not match at a +newline. This behaviour (for ^, $, and dot) is the same as Perl. +

+

+When PCRE2_MULTILINE it is set, the "start of line" and "end of line" +constructs match immediately following or immediately before internal newlines +in the subject string, respectively, as well as at the very start and end. This +is equivalent to Perl's /m option, and it can be changed within a pattern by a +(?m) option setting. Note that the "start of line" metacharacter does not match +after a newline at the end of the subject, for compatibility with Perl. +However, you can change this by setting the PCRE2_ALT_CIRCUMFLEX option. If +there are no newlines in a subject string, or no occurrences of ^ or $ in a +pattern, setting PCRE2_MULTILINE has no effect. +

+  PCRE2_NEVER_BACKSLASH_C
+
+This option locks out the use of \C in the pattern that is being compiled. +This escape can cause unpredictable behaviour in UTF-8 or UTF-16 modes, because +it may leave the current matching point in the middle of a multi-code-unit +character. This option may be useful in applications that process patterns from +external sources. Note that there is also a build-time option that permanently +locks out the use of \C. +
+  PCRE2_NEVER_UCP
+
+This option locks out the use of Unicode properties for handling \B, \b, \D, +\d, \S, \s, \W, \w, and some of the POSIX character classes, as described +for the PCRE2_UCP option below. In particular, it prevents the creator of the +pattern from enabling this facility by starting the pattern with (*UCP). This +option may be useful in applications that process patterns from external +sources. The option combination PCRE_UCP and PCRE_NEVER_UCP causes an error. +
+  PCRE2_NEVER_UTF
+
+This option locks out interpretation of the pattern as UTF-8, UTF-16, or +UTF-32, depending on which library is in use. In particular, it prevents the +creator of the pattern from switching to UTF interpretation by starting the +pattern with (*UTF). This option may be useful in applications that process +patterns from external sources. The combination of PCRE2_UTF and +PCRE2_NEVER_UTF causes an error. +
+  PCRE2_NO_AUTO_CAPTURE
+
+If this option is set, it disables the use of numbered capturing parentheses in +the pattern. Any opening parenthesis that is not followed by ? behaves as if it +were followed by ?: but named parentheses can still be used for capturing (and +they acquire numbers in the usual way). This is the same as Perl's /n option. +Note that, when this option is set, references to capture groups +(backreferences or recursion/subroutine calls) may only refer to named groups, +though the reference can be by name or by number. +
+  PCRE2_NO_AUTO_POSSESS
+
+If this option is set, it disables "auto-possessification", which is an +optimization that, for example, turns a+b into a++b in order to avoid +backtracks into a+ that can never be successful. However, if callouts are in +use, auto-possessification means that some callouts are never taken. You can +set this option if you want the matching functions to do a full unoptimized +search and run all the callouts, but it is mainly provided for testing +purposes. +
+  PCRE2_NO_DOTSTAR_ANCHOR
+
+If this option is set, it disables an optimization that is applied when .* is +the first significant item in a top-level branch of a pattern, and all the +other branches also start with .* or with \A or \G or ^. The optimization is +automatically disabled for .* if it is inside an atomic group or a capture +group that is the subject of a backreference, or if the pattern contains +(*PRUNE) or (*SKIP). When the optimization is not disabled, such a pattern is +automatically anchored if PCRE2_DOTALL is set for all the .* items and +PCRE2_MULTILINE is not set for any ^ items. Otherwise, the fact that any match +must start either at the start of the subject or following a newline is +remembered. Like other optimizations, this can cause callouts to be skipped. +
+  PCRE2_NO_START_OPTIMIZE
+
+This is an option whose main effect is at matching time. It does not change +what pcre2_compile() generates, but it does affect the output of the JIT +compiler. +

+

+There are a number of optimizations that may occur at the start of a match, in +order to speed up the process. For example, if it is known that an unanchored +match must start with a specific code unit value, the matching code searches +the subject for that value, and fails immediately if it cannot find it, without +actually running the main matching function. This means that a special item +such as (*COMMIT) at the start of a pattern is not considered until after a +suitable starting point for the match has been found. Also, when callouts or +(*MARK) items are in use, these "start-up" optimizations can cause them to be +skipped if the pattern is never actually used. The start-up optimizations are +in effect a pre-scan of the subject that takes place before the pattern is run. +

+

+The PCRE2_NO_START_OPTIMIZE option disables the start-up optimizations, +possibly causing performance to suffer, but ensuring that in cases where the +result is "no match", the callouts do occur, and that items such as (*COMMIT) +and (*MARK) are considered at every possible starting position in the subject +string. +

+

+Setting PCRE2_NO_START_OPTIMIZE may change the outcome of a matching operation. +Consider the pattern +

+  (*COMMIT)ABC
+
+When this is compiled, PCRE2 records the fact that a match must start with the +character "A". Suppose the subject string is "DEFABC". The start-up +optimization scans along the subject, finds "A" and runs the first match +attempt from there. The (*COMMIT) item means that the pattern must match the +current starting position, which in this case, it does. However, if the same +match is run with PCRE2_NO_START_OPTIMIZE set, the initial scan along the +subject string does not happen. The first match attempt is run starting from +"D" and when this fails, (*COMMIT) prevents any further matches being tried, so +the overall result is "no match". +

+

+As another start-up optimization makes use of a minimum length for a matching +subject, which is recorded when possible. Consider the pattern +

+  (*MARK:1)B(*MARK:2)(X|Y)
+
+The minimum length for a match is two characters. If the subject is "XXBB", the +"starting character" optimization skips "XX", then tries to match "BB", which +is long enough. In the process, (*MARK:2) is encountered and remembered. When +the match attempt fails, the next "B" is found, but there is only one character +left, so there are no more attempts, and "no match" is returned with the "last +mark seen" set to "2". If NO_START_OPTIMIZE is set, however, matches are tried +at every possible starting position, including at the end of the subject, where +(*MARK:1) is encountered, but there is no "B", so the "last mark seen" that is +returned is "1". In this case, the optimizations do not affect the overall +match result, which is still "no match", but they do affect the auxiliary +information that is returned. +
+  PCRE2_NO_UTF_CHECK
+
+When PCRE2_UTF is set, the validity of the pattern as a UTF string is +automatically checked. There are discussions about the validity of +UTF-8 strings, +UTF-16 strings, +and +UTF-32 strings +in the +pcre2unicode +document. If an invalid UTF sequence is found, pcre2_compile() returns a +negative error code. +

+

+If you know that your pattern is a valid UTF string, and you want to skip this +check for performance reasons, you can set the PCRE2_NO_UTF_CHECK option. When +it is set, the effect of passing an invalid UTF string as a pattern is +undefined. It may cause your program to crash or loop. +

+

+Note that this option can also be passed to pcre2_match() and +pcre2_dfa_match(), to suppress UTF validity checking of the subject +string. +

+

+Note also that setting PCRE2_NO_UTF_CHECK at compile time does not disable the +error that is given if an escape sequence for an invalid Unicode code point is +encountered in the pattern. In particular, the so-called "surrogate" code +points (0xd800 to 0xdfff) are invalid. If you want to allow escape sequences +such as \x{d800} you can set the PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES extra +option, as described in the section entitled "Extra compile options" +below. +However, this is possible only in UTF-8 and UTF-32 modes, because these values +are not representable in UTF-16. +

+  PCRE2_UCP
+
+This option has two effects. Firstly, it change the way PCRE2 processes \B, +\b, \D, \d, \S, \s, \W, \w, and some of the POSIX character classes. By +default, only ASCII characters are recognized, but if PCRE2_UCP is set, Unicode +properties are used to classify characters. There are some PCRE2_EXTRA +options (see below) that add finer control to this behaviour. More details are +given in the section on +generic character types +in the +pcre2pattern +page. +

+

+The second effect of PCRE2_UCP is to force the use of Unicode properties for +upper/lower casing operations, even when PCRE2_UTF is not set. This makes it +possible to process strings in the 16-bit UCS-2 code. This option is available +only if PCRE2 has been compiled with Unicode support (which is the default). +The PCRE2_EXTRA_CASELESS_RESTRICT option (see below) restricts caseless +matching such that ASCII characters match only ASCII characters and non-ASCII +characters match only non-ASCII characters. +

+  PCRE2_UNGREEDY
+
+This option inverts the "greediness" of the quantifiers so that they are not +greedy by default, but become greedy if followed by "?". It is not compatible +with Perl. It can also be set by a (?U) option setting within the pattern. +
+  PCRE2_USE_OFFSET_LIMIT
+
+This option must be set for pcre2_compile() if +pcre2_set_offset_limit() is going to be used to set a non-default offset +limit in a match context for matches that use this pattern. An error is +generated if an offset limit is set without this option. For more details, see +the description of pcre2_set_offset_limit() in the +section +that describes match contexts. See also the PCRE2_FIRSTLINE +option above. +
+  PCRE2_UTF
+
+This option causes PCRE2 to regard both the pattern and the subject strings +that are subsequently processed as strings of UTF characters instead of +single-code-unit strings. It is available when PCRE2 is built to include +Unicode support (which is the default). If Unicode support is not available, +the use of this option provokes an error. Details of how PCRE2_UTF changes the +behaviour of PCRE2 are given in the +pcre2unicode +page. In particular, note that it changes the way PCRE2_CASELESS works. +

+
+Extra compile options +
+

+The option bits that can be set in a compile context by calling the +pcre2_set_compile_extra_options() function are as follows: +

+  PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK
+
+Since release 10.38 PCRE2 has forbidden the use of \K within lookaround +assertions, following Perl's lead. This option is provided to re-enable the +previous behaviour (act in positive lookarounds, ignore in negative ones) in +case anybody is relying on it. +
+  PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES
+
+This option applies when compiling a pattern in UTF-8 or UTF-32 mode. It is +forbidden in UTF-16 mode, and ignored in non-UTF modes. Unicode "surrogate" +code points in the range 0xd800 to 0xdfff are used in pairs in UTF-16 to encode +code points with values in the range 0x10000 to 0x10ffff. The surrogates cannot +therefore be represented in UTF-16. They can be represented in UTF-8 and +UTF-32, but are defined as invalid code points, and cause errors if encountered +in a UTF-8 or UTF-32 string that is being checked for validity by PCRE2. +

+

+These values also cause errors if encountered in escape sequences such as +\x{d912} within a pattern. However, it seems that some applications, when +using PCRE2 to check for unwanted characters in UTF-8 strings, explicitly test +for the surrogates using escape sequences. The PCRE2_NO_UTF_CHECK option does +not disable the error that occurs, because it applies only to the testing of +input strings for UTF validity. +

+

+If the extra option PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES is set, surrogate code +point values in UTF-8 and UTF-32 patterns no longer provoke errors and are +incorporated in the compiled pattern. However, they can only match subject +characters if the matching function is called with PCRE2_NO_UTF_CHECK set. +

+  PCRE2_EXTRA_ALT_BSUX
+
+The original option PCRE2_ALT_BSUX causes PCRE2 to process \U, \u, and \x in +the way that ECMAscript (aka JavaScript) does. Additional functionality was +defined by ECMAscript 6; setting PCRE2_EXTRA_ALT_BSUX has the effect of +PCRE2_ALT_BSUX, but in addition it recognizes \u{hhh..} as a hexadecimal +character code, where hhh.. is any number of hexadecimal digits. +
+  PCRE2_EXTRA_ASCII_BSD
+
+This option forces \d to match only ASCII digits, even when PCRE2_UCP is set. +It can be changed within a pattern by means of the (?aD) option setting. +
+  PCRE2_EXTRA_ASCII_BSS
+
+This option forces \s to match only ASCII space characters, even when +PCRE2_UCP is set. It can be changed within a pattern by means of the (?aS) +option setting. +
+  PCRE2_EXTRA_ASCII_BSW
+
+This option forces \w to match only ASCII word characters, even when PCRE2_UCP +is set. It can be changed within a pattern by means of the (?aW) option +setting. +
+  PCRE2_EXTRA_ASCII_DIGIT
+
+This option forces the POSIX character classes [:digit:] and [:xdigit:] to +match only ASCII digits, even when PCRE2_UCP is set. It can be changed within +a pattern by means of the (?aT) option setting. +
+  PCRE2_EXTRA_ASCII_POSIX
+
+This option forces all the POSIX character classes, including [:digit:] and +[:xdigit:], to match only ASCII characters, even when PCRE2_UCP is set. It can +be changed within a pattern by means of the (?aP) option setting, but note that +this also sets PCRE2_EXTRA_ASCII_DIGIT in order to ensure that (?-aP) unsets +all ASCII restrictions for POSIX classes. +
+  PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL
+
+This is a dangerous option. Use with care. By default, an unrecognized escape +such as \j or a malformed one such as \x{2z} causes a compile-time error when +detected by pcre2_compile(). Perl is somewhat inconsistent in handling +such items: for example, \j is treated as a literal "j", and non-hexadecimal +digits in \x{} are just ignored, though warnings are given in both cases if +Perl's warning switch is enabled. However, a malformed octal number after \o{ +always causes an error in Perl. +

+

+If the PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL extra option is passed to +pcre2_compile(), all unrecognized or malformed escape sequences are +treated as single-character escapes. For example, \j is a literal "j" and +\x{2z} is treated as the literal string "x{2z}". Setting this option means +that typos in patterns may go undetected and have unexpected results. Also note +that a sequence such as [\N{] is interpreted as a malformed attempt at +[\N{...}] and so is treated as [N{] whereas [\N] gives an error because an +unqualified \N is a valid escape sequence but is not supported in a character +class. To reiterate: this is a dangerous option. Use with great care. +

+  PCRE2_EXTRA_CASELESS_RESTRICT
+
+When either PCRE2_UCP or PCRE2_UTF is set, caseless matching follows Unicode +rules, which allow for more than two cases per character. There are two +case-equivalent character sets that contain both ASCII and non-ASCII +characters. The ASCII letter S is case-equivalent to U+017f (long S) and the +ASCII letter K is case-equivalent to U+212a (Kelvin sign). This option disables +recognition of case-equivalences that cross the ASCII/non-ASCII boundary. In a +caseless match, both characters must either be ASCII or non-ASCII. The option +can be changed with a pattern by the (?r) option setting. +
+  PCRE2_EXTRA_ESCAPED_CR_IS_LF
+
+There are some legacy applications where the escape sequence \r in a pattern +is expected to match a newline. If this option is set, \r in a pattern is +converted to \n so that it matches a LF (linefeed) instead of a CR (carriage +return) character. The option does not affect a literal CR in the pattern, nor +does it affect CR specified as an explicit code point such as \x{0D}. +
+  PCRE2_EXTRA_MATCH_LINE
+
+This option is provided for use by the -x option of pcre2grep. It +causes the pattern only to match complete lines. This is achieved by +automatically inserting the code for "^(?:" at the start of the compiled +pattern and ")$" at the end. Thus, when PCRE2_MULTILINE is set, the matched +line may be in the middle of the subject string. This option can be used with +PCRE2_LITERAL. +
+  PCRE2_EXTRA_MATCH_WORD
+
+This option is provided for use by the -w option of pcre2grep. It +causes the pattern only to match strings that have a word boundary at the start +and the end. This is achieved by automatically inserting the code for "\b(?:" +at the start of the compiled pattern and ")\b" at the end. The option may be +used with PCRE2_LITERAL. However, it is ignored if PCRE2_EXTRA_MATCH_LINE is +also set. +

+
JUST-IN-TIME (JIT) COMPILATION
+

+int pcre2_jit_compile(pcre2_code *code, uint32_t options); +
+
+int pcre2_jit_match(const pcre2_code *code, PCRE2_SPTR subject, + PCRE2_SIZE length, PCRE2_SIZE startoffset, + uint32_t options, pcre2_match_data *match_data, + pcre2_match_context *mcontext); +
+
+void pcre2_jit_free_unused_memory(pcre2_general_context *gcontext); +
+
+pcre2_jit_stack *pcre2_jit_stack_create(size_t startsize, + size_t maxsize, pcre2_general_context *gcontext); +
+
+void pcre2_jit_stack_assign(pcre2_match_context *mcontext, + pcre2_jit_callback callback_function, void *callback_data); +
+
+void pcre2_jit_stack_free(pcre2_jit_stack *jit_stack); +

+

+These functions provide support for JIT compilation, which, if the just-in-time +compiler is available, further processes a compiled pattern into machine code +that executes much faster than the pcre2_match() interpretive matching +function. Full details are given in the +pcre2jit +documentation. +

+

+JIT compilation is a heavyweight optimization. It can take some time for +patterns to be analyzed, and for one-off matches and simple patterns the +benefit of faster execution might be offset by a much slower compilation time. +Most (but not all) patterns can be optimized by the JIT compiler. +

+
LOCALE SUPPORT
+

+const uint8_t *pcre2_maketables(pcre2_general_context *gcontext); +
+
+void pcre2_maketables_free(pcre2_general_context *gcontext, + const uint8_t *tables); +

+

+PCRE2 handles caseless matching, and determines whether characters are letters, +digits, or whatever, by reference to a set of tables, indexed by character code +point. However, this applies only to characters whose code points are less than +256. By default, higher-valued code points never match escapes such as \w or +\d. +

+

+When PCRE2 is built with Unicode support (the default), certain Unicode +character properties can be tested with \p and \P, or, alternatively, the +PCRE2_UCP option can be set when a pattern is compiled; this causes \w and +friends to use Unicode property support instead of the built-in tables. +PCRE2_UCP also causes upper/lower casing operations on characters with code +points greater than 127 to use Unicode properties. These effects apply even +when PCRE2_UTF is not set. There are, however, some PCRE2_EXTRA options (see +above) that can be used to modify or suppress them. +

+

+The use of locales with Unicode is discouraged. If you are handling characters +with code points greater than 127, you should either use Unicode support, or +use locales, but not try to mix the two. +

+

+PCRE2 contains a built-in set of character tables that are used by default. +These are sufficient for many applications. Normally, the internal tables +recognize only ASCII characters. However, when PCRE2 is built, it is possible +to cause the internal tables to be rebuilt in the default "C" locale of the +local system, which may cause them to be different. +

+

+The built-in tables can be overridden by tables supplied by the application +that calls PCRE2. These may be created in a different locale from the default. +As more and more applications change to using Unicode, the need for this locale +support is expected to die away. +

+

+External tables are built by calling the pcre2_maketables() function, in +the relevant locale. The only argument to this function is a general context, +which can be used to pass a custom memory allocator. If the argument is NULL, +the system malloc() is used. The result can be passed to +pcre2_compile() as often as necessary, by creating a compile context and +calling pcre2_set_character_tables() to set the tables pointer therein. +

+

+For example, to build and use tables that are appropriate for the French locale +(where accented characters with values greater than 127 are treated as +letters), the following code could be used: +

+  setlocale(LC_CTYPE, "fr_FR");
+  tables = pcre2_maketables(NULL);
+  ccontext = pcre2_compile_context_create(NULL);
+  pcre2_set_character_tables(ccontext, tables);
+  re = pcre2_compile(..., ccontext);
+
+The locale name "fr_FR" is used on Linux and other Unix-like systems; if you +are using Windows, the name for the French locale is "french". +

+

+The pointer that is passed (via the compile context) to pcre2_compile() +is saved with the compiled pattern, and the same tables are used by the +matching functions. Thus, for any single pattern, compilation and matching both +happen in the same locale, but different patterns can be processed in different +locales. +

+

+It is the caller's responsibility to ensure that the memory containing the +tables remains available while they are still in use. When they are no longer +needed, you can discard them using pcre2_maketables_free(), which should +pass as its first parameter the same global context that was used to create the +tables. +

+
+Saving locale tables +
+

+The tables described above are just a sequence of binary bytes, which makes +them independent of hardware characteristics such as endianness or whether the +processor is 32-bit or 64-bit. A copy of the result of pcre2_maketables() +can therefore be saved in a file or elsewhere and re-used later, even in a +different program or on another computer. The size of the tables (number of +bytes) must be obtained by calling pcre2_config() with the +PCRE2_CONFIG_TABLES_LENGTH option because pcre2_maketables() does not +return this value. Note that the pcre2_dftables program, which is part of +the PCRE2 build system, can be used stand-alone to create a file that contains +a set of binary tables. See the +pcre2build +documentation for details. +

+
INFORMATION ABOUT A COMPILED PATTERN
+

+int pcre2_pattern_info(const pcre2 *code, uint32_t what, void *where); +

+

+The pcre2_pattern_info() function returns general information about a +compiled pattern. For information about callouts, see the +next section. +The first argument for pcre2_pattern_info() is a pointer to the compiled +pattern. The second argument specifies which piece of information is required, +and the third argument is a pointer to a variable to receive the data. If the +third argument is NULL, the first argument is ignored, and the function returns +the size in bytes of the variable that is required for the information +requested. Otherwise, the yield of the function is zero for success, or one of +the following negative numbers: +

+  PCRE2_ERROR_NULL           the argument code was NULL
+  PCRE2_ERROR_BADMAGIC       the "magic number" was not found
+  PCRE2_ERROR_BADOPTION      the value of what was invalid
+  PCRE2_ERROR_UNSET          the requested field is not set
+
+The "magic number" is placed at the start of each compiled pattern as a simple +check against passing an arbitrary memory pointer. Here is a typical call of +pcre2_pattern_info(), to obtain the length of the compiled pattern: +
+  int rc;
+  size_t length;
+  rc = pcre2_pattern_info(
+    re,               /* result of pcre2_compile() */
+    PCRE2_INFO_SIZE,  /* what is required */
+    &length);         /* where to put the data */
+
+The possible values for the second argument are defined in pcre2.h, and +are as follows: +
+  PCRE2_INFO_ALLOPTIONS
+  PCRE2_INFO_ARGOPTIONS
+  PCRE2_INFO_EXTRAOPTIONS
+
+Return copies of the pattern's options. The third argument should point to a +uint32_t variable. PCRE2_INFO_ARGOPTIONS returns exactly the options that +were passed to pcre2_compile(), whereas PCRE2_INFO_ALLOPTIONS returns +the compile options as modified by any top-level (*XXX) option settings such as +(*UTF) at the start of the pattern itself. PCRE2_INFO_EXTRAOPTIONS returns the +extra options that were set in the compile context by calling the +pcre2_set_compile_extra_options() function. +

+

+For example, if the pattern /(*UTF)abc/ is compiled with the PCRE2_EXTENDED +option, the result for PCRE2_INFO_ALLOPTIONS is PCRE2_EXTENDED and PCRE2_UTF. +Option settings such as (?i) that can change within a pattern do not affect the +result of PCRE2_INFO_ALLOPTIONS, even if they appear right at the start of the +pattern. (This was different in some earlier releases.) +

+

+A pattern compiled without PCRE2_ANCHORED is automatically anchored by PCRE2 if +the first significant item in every top-level branch is one of the following: +

+  ^     unless PCRE2_MULTILINE is set
+  \A    always
+  \G    always
+  .*    sometimes - see below
+
+When .* is the first significant item, anchoring is possible only when all the +following are true: +
+  .* is not in an atomic group
+  .* is not in a capture group that is the subject of a backreference
+  PCRE2_DOTALL is in force for .*
+  Neither (*PRUNE) nor (*SKIP) appears in the pattern
+  PCRE2_NO_DOTSTAR_ANCHOR is not set
+
+For patterns that are auto-anchored, the PCRE2_ANCHORED bit is set in the +options returned for PCRE2_INFO_ALLOPTIONS. +
+  PCRE2_INFO_BACKREFMAX
+
+Return the number of the highest backreference in the pattern. The third +argument should point to a uint32_t variable. Named capture groups +acquire numbers as well as names, and these count towards the highest +backreference. Backreferences such as \4 or \g{12} match the captured +characters of the given group, but in addition, the check that a capture +group is set in a conditional group such as (?(3)a|b) is also a backreference. +Zero is returned if there are no backreferences. +
+  PCRE2_INFO_BSR
+
+The output is a uint32_t integer whose value indicates what character sequences +the \R escape sequence matches. A value of PCRE2_BSR_UNICODE means that \R +matches any Unicode line ending sequence; a value of PCRE2_BSR_ANYCRLF means +that \R matches only CR, LF, or CRLF. +
+  PCRE2_INFO_CAPTURECOUNT
+
+Return the highest capture group number in the pattern. In patterns where (?| +is not used, this is also the total number of capture groups. The third +argument should point to a uint32_t variable. +
+  PCRE2_INFO_DEPTHLIMIT
+
+If the pattern set a backtracking depth limit by including an item of the form +(*LIMIT_DEPTH=nnnn) at the start, the value is returned. The third argument +should point to a uint32_t integer. If no such value has been set, the call to +pcre2_pattern_info() returns the error PCRE2_ERROR_UNSET. Note that this +limit will only be used during matching if it is less than the limit set or +defaulted by the caller of the match function. +
+  PCRE2_INFO_FIRSTBITMAP
+
+In the absence of a single first code unit for a non-anchored pattern, +pcre2_compile() may construct a 256-bit table that defines a fixed set of +values for the first code unit in any match. For example, a pattern that starts +with [abc] results in a table with three bits set. When code unit values +greater than 255 are supported, the flag bit for 255 means "any code unit of +value 255 or above". If such a table was constructed, a pointer to it is +returned. Otherwise NULL is returned. The third argument should point to a +const uint8_t * variable. +
+  PCRE2_INFO_FIRSTCODETYPE
+
+Return information about the first code unit of any matched string, for a +non-anchored pattern. The third argument should point to a uint32_t +variable. If there is a fixed first value, for example, the letter "c" from a +pattern such as (cat|cow|coyote), 1 is returned, and the value can be retrieved +using PCRE2_INFO_FIRSTCODEUNIT. If there is no fixed first value, but it is +known that a match can occur only at the start of the subject or following a +newline in the subject, 2 is returned. Otherwise, and for anchored patterns, 0 +is returned. +
+  PCRE2_INFO_FIRSTCODEUNIT
+
+Return the value of the first code unit of any matched string for a pattern +where PCRE2_INFO_FIRSTCODETYPE returns 1; otherwise return 0. The third +argument should point to a uint32_t variable. In the 8-bit library, the +value is always less than 256. In the 16-bit library the value can be up to +0xffff. In the 32-bit library in UTF-32 mode the value can be up to 0x10ffff, +and up to 0xffffffff when not using UTF-32 mode. +
+  PCRE2_INFO_FRAMESIZE
+
+Return the size (in bytes) of the data frames that are used to remember +backtracking positions when the pattern is processed by pcre2_match() +without the use of JIT. The third argument should point to a size_t +variable. The frame size depends on the number of capturing parentheses in the +pattern. Each additional capture group adds two PCRE2_SIZE variables. +
+  PCRE2_INFO_HASBACKSLASHC
+
+Return 1 if the pattern contains any instances of \C, otherwise 0. The third +argument should point to a uint32_t variable. +
+  PCRE2_INFO_HASCRORLF
+
+Return 1 if the pattern contains any explicit matches for CR or LF characters, +otherwise 0. The third argument should point to a uint32_t variable. An +explicit match is either a literal CR or LF character, or \r or \n or one of +the equivalent hexadecimal or octal escape sequences. +
+  PCRE2_INFO_HEAPLIMIT
+
+If the pattern set a heap memory limit by including an item of the form +(*LIMIT_HEAP=nnnn) at the start, the value is returned. The third argument +should point to a uint32_t integer. If no such value has been set, the call to +pcre2_pattern_info() returns the error PCRE2_ERROR_UNSET. Note that this +limit will only be used during matching if it is less than the limit set or +defaulted by the caller of the match function. +
+  PCRE2_INFO_JCHANGED
+
+Return 1 if the (?J) or (?-J) option setting is used in the pattern, otherwise +0. The third argument should point to a uint32_t variable. (?J) and +(?-J) set and unset the local PCRE2_DUPNAMES option, respectively. +
+  PCRE2_INFO_JITSIZE
+
+If the compiled pattern was successfully processed by +pcre2_jit_compile(), return the size of the JIT compiled code, otherwise +return zero. The third argument should point to a size_t variable. +
+  PCRE2_INFO_LASTCODETYPE
+
+Returns 1 if there is a rightmost literal code unit that must exist in any +matched string, other than at its start. The third argument should point to a +uint32_t variable. If there is no such value, 0 is returned. When 1 is +returned, the code unit value itself can be retrieved using +PCRE2_INFO_LASTCODEUNIT. For anchored patterns, a last literal value is +recorded only if it follows something of variable length. For example, for the +pattern /^a\d+z\d+/ the returned value is 1 (with "z" returned from +PCRE2_INFO_LASTCODEUNIT), but for /^a\dz\d/ the returned value is 0. +
+  PCRE2_INFO_LASTCODEUNIT
+
+Return the value of the rightmost literal code unit that must exist in any +matched string, other than at its start, for a pattern where +PCRE2_INFO_LASTCODETYPE returns 1. Otherwise, return 0. The third argument +should point to a uint32_t variable. +
+  PCRE2_INFO_MATCHEMPTY
+
+Return 1 if the pattern might match an empty string, otherwise 0. The third +argument should point to a uint32_t variable. When a pattern contains +recursive subroutine calls it is not always possible to determine whether or +not it can match an empty string. PCRE2 takes a cautious approach and returns 1 +in such cases. +
+  PCRE2_INFO_MATCHLIMIT
+
+If the pattern set a match limit by including an item of the form +(*LIMIT_MATCH=nnnn) at the start, the value is returned. The third argument +should point to a uint32_t integer. If no such value has been set, the call to +pcre2_pattern_info() returns the error PCRE2_ERROR_UNSET. Note that this +limit will only be used during matching if it is less than the limit set or +defaulted by the caller of the match function. +
+  PCRE2_INFO_MAXLOOKBEHIND
+
+A lookbehind assertion moves back a certain number of characters (not code +units) when it starts to process each of its branches. This request returns the +largest of these backward moves. The third argument should point to a uint32_t +integer. The simple assertions \b and \B require a one-character lookbehind +and cause PCRE2_INFO_MAXLOOKBEHIND to return 1 in the absence of anything +longer. \A also registers a one-character lookbehind, though it does not +actually inspect the previous character. +

+

+Note that this information is useful for multi-segment matching only +if the pattern contains no nested lookbehinds. For example, the pattern +(?<=a(?<=ba)c) returns a maximum lookbehind of 2, but when it is processed, the +first lookbehind moves back by two characters, matches one character, then the +nested lookbehind also moves back by two characters. This puts the matching +point three characters earlier than it was at the start. +PCRE2_INFO_MAXLOOKBEHIND is really only useful as a debugging tool. See the +pcre2partial +documentation for a discussion of multi-segment matching. +

+  PCRE2_INFO_MINLENGTH
+
+If a minimum length for matching subject strings was computed, its value is +returned. Otherwise the returned value is 0. This value is not computed when +PCRE2_NO_START_OPTIMIZE is set. The value is a number of characters, which in +UTF mode may be different from the number of code units. The third argument +should point to a uint32_t variable. The value is a lower bound to the +length of any matching string. There may not be any strings of that length that +do actually match, but every string that does match is at least that long. +
+  PCRE2_INFO_NAMECOUNT
+  PCRE2_INFO_NAMEENTRYSIZE
+  PCRE2_INFO_NAMETABLE
+
+PCRE2 supports the use of named as well as numbered capturing parentheses. The +names are just an additional way of identifying the parentheses, which still +acquire numbers. Several convenience functions such as +pcre2_substring_get_byname() are provided for extracting captured +substrings by name. It is also possible to extract the data directly, by first +converting the name to a number in order to access the correct pointers in the +output vector (described with pcre2_match() below). To do the conversion, +you need to use the name-to-number map, which is described by these three +values. +

+

+The map consists of a number of fixed-size entries. PCRE2_INFO_NAMECOUNT gives +the number of entries, and PCRE2_INFO_NAMEENTRYSIZE gives the size of each +entry in code units; both of these return a uint32_t value. The entry +size depends on the length of the longest name. +

+

+PCRE2_INFO_NAMETABLE returns a pointer to the first entry of the table. This is +a PCRE2_SPTR pointer to a block of code units. In the 8-bit library, the first +two bytes of each entry are the number of the capturing parenthesis, most +significant byte first. In the 16-bit library, the pointer points to 16-bit +code units, the first of which contains the parenthesis number. In the 32-bit +library, the pointer points to 32-bit code units, the first of which contains +the parenthesis number. The rest of the entry is the corresponding name, zero +terminated. +

+

+The names are in alphabetical order. If (?| is used to create multiple capture +groups with the same number, as described in the +section on duplicate group numbers +in the +pcre2pattern +page, the groups may be given the same name, but there is only one entry in the +table. Different names for groups of the same number are not permitted. +

+

+Duplicate names for capture groups with different numbers are permitted, but +only if PCRE2_DUPNAMES is set. They appear in the table in the order in which +they were found in the pattern. In the absence of (?| this is the order of +increasing number; when (?| is used this is not necessarily the case because +later capture groups may have lower numbers. +

+

+As a simple example of the name/number table, consider the following pattern +after compilation by the 8-bit library (assume PCRE2_EXTENDED is set, so white +space - including newlines - is ignored): +

+  (?<date> (?<year>(\d\d)?\d\d) - (?<month>\d\d) - (?<day>\d\d) )
+
+There are four named capture groups, so the table has four entries, and each +entry in the table is eight bytes long. The table is as follows, with +non-printing bytes shows in hexadecimal, and undefined bytes shown as ??: +
+  00 01 d  a  t  e  00 ??
+  00 05 d  a  y  00 ?? ??
+  00 04 m  o  n  t  h  00
+  00 02 y  e  a  r  00 ??
+
+When writing code to extract data from named capture groups using the +name-to-number map, remember that the length of the entries is likely to be +different for each compiled pattern. +
+  PCRE2_INFO_NEWLINE
+
+The output is one of the following uint32_t values: +
+  PCRE2_NEWLINE_CR       Carriage return (CR)
+  PCRE2_NEWLINE_LF       Linefeed (LF)
+  PCRE2_NEWLINE_CRLF     Carriage return, linefeed (CRLF)
+  PCRE2_NEWLINE_ANY      Any Unicode line ending
+  PCRE2_NEWLINE_ANYCRLF  Any of CR, LF, or CRLF
+  PCRE2_NEWLINE_NUL      The NUL character (binary zero)
+
+This identifies the character sequence that will be recognized as meaning +"newline" while matching. +
+  PCRE2_INFO_SIZE
+
+Return the size of the compiled pattern in bytes (for all three libraries). The +third argument should point to a size_t variable. This value includes the +size of the general data block that precedes the code units of the compiled +pattern itself. The value that is used when pcre2_compile() is getting +memory in which to place the compiled pattern may be slightly larger than the +value returned by this option, because there are cases where the code that +calculates the size has to over-estimate. Processing a pattern with the JIT +compiler does not alter the value returned by this option. +

+
INFORMATION ABOUT A PATTERN'S CALLOUTS
+

+int pcre2_callout_enumerate(const pcre2_code *code, + int (*callback)(pcre2_callout_enumerate_block *, void *), + void *user_data); +
+
+A script language that supports the use of string arguments in callouts might +like to scan all the callouts in a pattern before running the match. This can +be done by calling pcre2_callout_enumerate(). The first argument is a +pointer to a compiled pattern, the second points to a callback function, and +the third is arbitrary user data. The callback function is called for every +callout in the pattern in the order in which they appear. Its first argument is +a pointer to a callout enumeration block, and its second argument is the +user_data value that was passed to pcre2_callout_enumerate(). The +contents of the callout enumeration block are described in the +pcre2callout +documentation, which also gives further details about callouts. +

+
SERIALIZATION AND PRECOMPILING
+

+It is possible to save compiled patterns on disc or elsewhere, and reload them +later, subject to a number of restrictions. The host on which the patterns are +reloaded must be running the same version of PCRE2, with the same code unit +width, and must also have the same endianness, pointer width, and PCRE2_SIZE +type. Before compiled patterns can be saved, they must be converted to a +"serialized" form, which in the case of PCRE2 is really just a bytecode dump. +The functions whose names begin with pcre2_serialize_ are used for +converting to and from the serialized form. They are described in the +pcre2serialize +documentation. Note that PCRE2 serialization does not convert compiled patterns +to an abstract format like Java or .NET serialization. +

+
THE MATCH DATA BLOCK
+

+pcre2_match_data *pcre2_match_data_create(uint32_t ovecsize, + pcre2_general_context *gcontext); +
+
+pcre2_match_data *pcre2_match_data_create_from_pattern( + const pcre2_code *code, pcre2_general_context *gcontext); +
+
+void pcre2_match_data_free(pcre2_match_data *match_data); +

+

+Information about a successful or unsuccessful match is placed in a match +data block, which is an opaque structure that is accessed by function calls. In +particular, the match data block contains a vector of offsets into the subject +string that define the matched parts of the subject. This is known as the +ovector. +

+

+Before calling pcre2_match(), pcre2_dfa_match(), or +pcre2_jit_match() you must create a match data block by calling one of +the creation functions above. For pcre2_match_data_create(), the first +argument is the number of pairs of offsets in the ovector. +

+

+When using pcre2_match(), one pair of offsets is required to identify the +string that matched the whole pattern, with an additional pair for each +captured substring. For example, a value of 4 creates enough space to record +the matched portion of the subject plus three captured substrings. +

+

+When using pcre2_dfa_match() there may be multiple matched substrings of +different lengths at the same point in the subject. The ovector should be made +large enough to hold as many as are expected. +

+

+A minimum of at least 1 pair is imposed by pcre2_match_data_create(), so +it is always possible to return the overall matched string in the case of +pcre2_match() or the longest match in the case of +pcre2_dfa_match(). The maximum number of pairs is 65535; if the first +argument of pcre2_match_data_create() is greater than this, 65535 is +used. +

+

+The second argument of pcre2_match_data_create() is a pointer to a +general context, which can specify custom memory management for obtaining the +memory for the match data block. If you are not using custom memory management, +pass NULL, which causes malloc() to be used. +

+

+For pcre2_match_data_create_from_pattern(), the first argument is a +pointer to a compiled pattern. The ovector is created to be exactly the right +size to hold all the substrings a pattern might capture when matched using +pcre2_match(). You should not use this call when matching with +pcre2_dfa_match(). The second argument is again a pointer to a general +context, but in this case if NULL is passed, the memory is obtained using the +same allocator that was used for the compiled pattern (custom or default). +

+

+A match data block can be used many times, with the same or different compiled +patterns. You can extract information from a match data block after a match +operation has finished, using functions that are described in the sections on +matched strings +and +other match data +below. +

+

+When a call of pcre2_match() fails, valid data is available in the match +block only when the error is PCRE2_ERROR_NOMATCH, PCRE2_ERROR_PARTIAL, or one +of the error codes for an invalid UTF string. Exactly what is available depends +on the error, and is detailed below. +

+

+When one of the matching functions is called, pointers to the compiled pattern +and the subject string are set in the match data block so that they can be +referenced by the extraction functions after a successful match. After running +a match, you must not free a compiled pattern or a subject string until after +all operations on the match data block (for that match) have taken place, +unless, in the case of the subject string, you have used the +PCRE2_COPY_MATCHED_SUBJECT option, which is described in the section entitled +"Option bits for pcre2_match()" +below. +

+

+When a match data block itself is no longer needed, it should be freed by +calling pcre2_match_data_free(). If this function is called with a NULL +argument, it returns immediately, without doing anything. +

+
MEMORY USE FOR MATCH DATA BLOCKS
+

+PCRE2_SIZE pcre2_get_match_data_size(pcre2_match_data *match_data); +
+
+PCRE2_SIZE pcre2_get_match_data_heapframes_size( + pcre2_match_data *match_data); +

+

+The size of a match data block depends on the size of the ovector that it +contains. The function pcre2_get_match_data_size() returns the size, in +bytes, of the block that is its argument. +

+

+When pcre2_match() runs interpretively (that is, without using JIT), it +makes use of a vector of data frames for remembering backtracking positions. +The size of each individual frame depends on the number of capturing +parentheses in the pattern and can be obtained by calling +pcre2_pattern_info() with the PCRE2_INFO_FRAMESIZE option (see the +section entitled "Information about a compiled pattern" +above). +

+

+Heap memory is used for the frames vector; if the initial memory block turns +out to be too small during matching, it is automatically expanded. When +pcre2_match() returns, the memory is not freed, but remains attached to +the match data block, for use by any subsequent matches that use the same +block. It is automatically freed when the match data block itself is freed. +

+

+You can find the current size of the frames vector that a match data block owns +by calling pcre2_get_match_data_heapframes_size(). For a newly created +match data block the size will be zero. Some types of match may require a lot +of frames and thus a large vector; applications that run in environments where +memory is constrained can check this and free the match data block if the heap +frames vector has become too big. +

+
MATCHING A PATTERN: THE TRADITIONAL FUNCTION
+

+int pcre2_match(const pcre2_code *code, PCRE2_SPTR subject, + PCRE2_SIZE length, PCRE2_SIZE startoffset, + uint32_t options, pcre2_match_data *match_data, + pcre2_match_context *mcontext); +

+

+The function pcre2_match() is called to match a subject string against a +compiled pattern, which is passed in the code argument. You can call +pcre2_match() with the same code argument as many times as you +like, in order to find multiple matches in the subject string or to match +different subject strings with the same pattern. +

+

+This function is the main matching facility of the library, and it operates in +a Perl-like manner. For specialist use there is also an alternative matching +function, which is described +below +in the section about the pcre2_dfa_match() function. +

+

+Here is an example of a simple call to pcre2_match(): +

+  pcre2_match_data *md = pcre2_match_data_create(4, NULL);
+  int rc = pcre2_match(

+If the subject string is zero-terminated, the length can be given as +PCRE2_ZERO_TERMINATED. A match context must be provided if certain less common +matching parameters are to be changed. For details, see the section on +the match context +above. +

+
+The string to be matched by pcre2_match() +
+

+The subject string is passed to pcre2_match() as a pointer in +subject, a length in length, and a starting offset in +startoffset. The length and offset are in code units, not characters. +That is, they are in bytes for the 8-bit library, 16-bit code units for the +16-bit library, and 32-bit code units for the 32-bit library, whether or not +UTF processing is enabled. As a special case, if subject is NULL and +length is zero, the subject is assumed to be an empty string. If +length is non-zero, an error occurs if subject is NULL. +

+

+If startoffset is greater than the length of the subject, +pcre2_match() returns PCRE2_ERROR_BADOFFSET. When the starting offset is +zero, the search for a match starts at the beginning of the subject, and this +is by far the most common case. In UTF-8 or UTF-16 mode, the starting offset +must point to the start of a character, or to the end of the subject (in UTF-32 +mode, one code unit equals one character, so all offsets are valid). Like the +pattern string, the subject may contain binary zeros. +

+

+A non-zero starting offset is useful when searching for another match in the +same subject by calling pcre2_match() again after a previous success. +Setting startoffset differs from passing over a shortened string and +setting PCRE2_NOTBOL in the case of a pattern that begins with any kind of +lookbehind. For example, consider the pattern +

+  \Biss\B
+
+which finds occurrences of "iss" in the middle of words. (\B matches only if +the current position in the subject is not a word boundary.) When applied to +the string "Mississippi" the first call to pcre2_match() finds the first +occurrence. If pcre2_match() is called again with just the remainder of +the subject, namely "issippi", it does not match, because \B is always false +at the start of the subject, which is deemed to be a word boundary. However, if +pcre2_match() is passed the entire string again, but with +startoffset set to 4, it finds the second occurrence of "iss" because it +is able to look behind the starting point to discover that it is preceded by a +letter. +

+

+Finding all the matches in a subject is tricky when the pattern can match an +empty string. It is possible to emulate Perl's /g behaviour by first trying the +match again at the same offset, with the PCRE2_NOTEMPTY_ATSTART and +PCRE2_ANCHORED options, and then if that fails, advancing the starting offset +and trying an ordinary match again. There is some code that demonstrates how to +do this in the +pcre2demo +sample program. In the most general case, you have to check to see if the +newline convention recognizes CRLF as a newline, and if so, and the current +character is CR followed by LF, advance the starting offset by two characters +instead of one. +

+

+If a non-zero starting offset is passed when the pattern is anchored, a single +attempt to match at the given offset is made. This can only succeed if the +pattern does not require the match to be at the start of the subject. In other +words, the anchoring must be the result of setting the PCRE2_ANCHORED option or +the use of .* with PCRE2_DOTALL, not by starting the pattern with ^ or \A. +

+
+Option bits for pcre2_match() +
+

+The unused bits of the options argument for pcre2_match() must be +zero. The only bits that may be set are PCRE2_ANCHORED, +PCRE2_COPY_MATCHED_SUBJECT, PCRE2_DISABLE_RECURSELOOP_CHECK, PCRE2_ENDANCHORED, +PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART, +PCRE2_NO_JIT, PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. +Their action is described below. +

+

+Setting PCRE2_ANCHORED or PCRE2_ENDANCHORED at match time is not supported by +the just-in-time (JIT) compiler. If it is set, JIT matching is disabled and the +interpretive code in pcre2_match() is run. +PCRE2_DISABLE_RECURSELOOP_CHECK is ignored by JIT, but apart from PCRE2_NO_JIT +(obviously), the remaining options are supported for JIT matching. +

+  PCRE2_ANCHORED
+
+The PCRE2_ANCHORED option limits pcre2_match() to matching at the first +matching position. If a pattern was compiled with PCRE2_ANCHORED, or turned out +to be anchored by virtue of its contents, it cannot be made unachored at +matching time. Note that setting the option at match time disables JIT +matching. +
+  PCRE2_COPY_MATCHED_SUBJECT
+
+By default, a pointer to the subject is remembered in the match data block so +that, after a successful match, it can be referenced by the substring +extraction functions. This means that the subject's memory must not be freed +until all such operations are complete. For some applications where the +lifetime of the subject string is not guaranteed, it may be necessary to make a +copy of the subject string, but it is wasteful to do this unless the match is +successful. After a successful match, if PCRE2_COPY_MATCHED_SUBJECT is set, the +subject is copied and the new pointer is remembered in the match data block +instead of the original subject pointer. The memory allocator that was used for +the match block itself is used. The copy is automatically freed when +pcre2_match_data_free() is called to free the match data block. It is also +automatically freed if the match data block is re-used for another match +operation. +
+  PCRE2_DISABLE_RECURSELOOP_CHECK
+
+This option is relevant only to pcre2_match() for interpretive matching. +It is ignored when JIT is used, and is forbidden for pcre2_dfa_match(). +

+

+The use of recursion in patterns can lead to infinite loops. In the +interpretive matcher these would be eventually caught by the match or heap +limits, but this could take a long time and/or use a lot of memory if the +limits are large. There is therefore a check at the start of each recursion. +If the same group is still active from a previous call, and the current subject +pointer is the same as it was at the start of that group, and the furthest +inspected character of the subject has not changed, an error is generated. +

+

+There are rare cases of matches that would complete, but nevertheless trigger +this error. This option disables the check. It is provided mainly for testing +when comparing JIT and interpretive behaviour. +

+  PCRE2_ENDANCHORED
+
+If the PCRE2_ENDANCHORED option is set, any string that pcre2_match() +matches must be right at the end of the subject string. Note that setting the +option at match time disables JIT matching. +
+  PCRE2_NOTBOL
+
+This option specifies that first character of the subject string is not the +beginning of a line, so the circumflex metacharacter should not match before +it. Setting this without having set PCRE2_MULTILINE at compile time causes +circumflex never to match. This option affects only the behaviour of the +circumflex metacharacter. It does not affect \A. +
+  PCRE2_NOTEOL
+
+This option specifies that the end of the subject string is not the end of a +line, so the dollar metacharacter should not match it nor (except in multiline +mode) a newline immediately before it. Setting this without having set +PCRE2_MULTILINE at compile time causes dollar never to match. This option +affects only the behaviour of the dollar metacharacter. It does not affect \Z +or \z. +
+  PCRE2_NOTEMPTY
+
+An empty string is not considered to be a valid match if this option is set. If +there are alternatives in the pattern, they are tried. If all the alternatives +match the empty string, the entire match fails. For example, if the pattern +
+  a?b?
+
+is applied to a string not beginning with "a" or "b", it matches an empty +string at the start of the subject. With PCRE2_NOTEMPTY set, this match is not +valid, so pcre2_match() searches further into the string for occurrences +of "a" or "b". +
+  PCRE2_NOTEMPTY_ATSTART
+
+This is like PCRE2_NOTEMPTY, except that it locks out an empty string match +only at the first matching position, that is, at the start of the subject plus +the starting offset. An empty string match later in the subject is permitted. +If the pattern is anchored, such a match can occur only if the pattern contains +\K. +
+  PCRE2_NO_JIT
+
+By default, if a pattern has been successfully processed by +pcre2_jit_compile(), JIT is automatically used when pcre2_match() +is called with options that JIT supports. Setting PCRE2_NO_JIT disables the use +of JIT; it forces matching to be done by the interpreter. +
+  PCRE2_NO_UTF_CHECK
+
+When PCRE2_UTF is set at compile time, the validity of the subject as a UTF +string is checked unless PCRE2_NO_UTF_CHECK is passed to pcre2_match() or +PCRE2_MATCH_INVALID_UTF was passed to pcre2_compile(). The latter special +case is discussed in detail in the +pcre2unicode +documentation. +

+

+In the default case, if a non-zero starting offset is given, the check is +applied only to that part of the subject that could be inspected during +matching, and there is a check that the starting offset points to the first +code unit of a character or to the end of the subject. If there are no +lookbehind assertions in the pattern, the check starts at the starting offset. +Otherwise, it starts at the length of the longest lookbehind before the +starting offset, or at the start of the subject if there are not that many +characters before the starting offset. Note that the sequences \b and \B are +one-character lookbehinds. +

+

+The check is carried out before any other processing takes place, and a +negative error code is returned if the check fails. There are several UTF error +codes for each code unit width, corresponding to different problems with the +code unit sequence. There are discussions about the validity of +UTF-8 strings, +UTF-16 strings, +and +UTF-32 strings +in the +pcre2unicode +documentation. +

+

+If you know that your subject is valid, and you want to skip this check for +performance reasons, you can set the PCRE2_NO_UTF_CHECK option when calling +pcre2_match(). You might want to do this for the second and subsequent +calls to pcre2_match() if you are making repeated calls to find multiple +matches in the same subject string. +

+

+Warning: Unless PCRE2_MATCH_INVALID_UTF was set at compile time, when +PCRE2_NO_UTF_CHECK is set at match time the effect of passing an invalid +string as a subject, or an invalid value of startoffset, is undefined. +Your program may crash or loop indefinitely or give wrong results. +

+  PCRE2_PARTIAL_HARD
+  PCRE2_PARTIAL_SOFT
+
+These options turn on the partial matching feature. A partial match occurs if +the end of the subject string is reached successfully, but there are not enough +subject characters to complete the match. In addition, either at least one +character must have been inspected or the pattern must contain a lookbehind, or +the pattern must be one that could match an empty string. +

+

+If this situation arises when PCRE2_PARTIAL_SOFT (but not PCRE2_PARTIAL_HARD) +is set, matching continues by testing any remaining alternatives. Only if no +complete match can be found is PCRE2_ERROR_PARTIAL returned instead of +PCRE2_ERROR_NOMATCH. In other words, PCRE2_PARTIAL_SOFT specifies that the +caller is prepared to handle a partial match, but only if no complete match can +be found. +

+

+If PCRE2_PARTIAL_HARD is set, it overrides PCRE2_PARTIAL_SOFT. In this case, if +a partial match is found, pcre2_match() immediately returns +PCRE2_ERROR_PARTIAL, without considering any other alternatives. In other +words, when PCRE2_PARTIAL_HARD is set, a partial match is considered to be more +important that an alternative complete match. +

+

+There is a more detailed discussion of partial and multi-segment matching, with +examples, in the +pcre2partial +documentation. +

+
NEWLINE HANDLING WHEN MATCHING
+

+When PCRE2 is built, a default newline convention is set; this is usually the +standard convention for the operating system. The default can be overridden in +a +compile context +by calling pcre2_set_newline(). It can also be overridden by starting a +pattern string with, for example, (*CRLF), as described in the +section on newline conventions +in the +pcre2pattern +page. During matching, the newline choice affects the behaviour of the dot, +circumflex, and dollar metacharacters. It may also alter the way the match +starting position is advanced after a match failure for an unanchored pattern. +

+

+When PCRE2_NEWLINE_CRLF, PCRE2_NEWLINE_ANYCRLF, or PCRE2_NEWLINE_ANY is set as +the newline convention, and a match attempt for an unanchored pattern fails +when the current starting position is at a CRLF sequence, and the pattern +contains no explicit matches for CR or LF characters, the match position is +advanced by two characters instead of one, in other words, to after the CRLF. +

+

+The above rule is a compromise that makes the most common cases work as +expected. For example, if the pattern is .+A (and the PCRE2_DOTALL option is +not set), it does not match the string "\r\nA" because, after failing at the +start, it skips both the CR and the LF before retrying. However, the pattern +[\r\n]A does match that string, because it contains an explicit CR or LF +reference, and so advances only by one character after the first failure. +

+

+An explicit match for CR of LF is either a literal appearance of one of those +characters in the pattern, or one of the \r or \n or equivalent octal or +hexadecimal escape sequences. Implicit matches such as [^X] do not count, nor +does \s, even though it includes CR and LF in the characters that it matches. +

+

+Notwithstanding the above, anomalous effects may still occur when CRLF is a +valid newline sequence and explicit \r or \n escapes appear in the pattern. +

+
HOW PCRE2_MATCH() RETURNS A STRING AND CAPTURED SUBSTRINGS
+

+uint32_t pcre2_get_ovector_count(pcre2_match_data *match_data); +
+
+PCRE2_SIZE *pcre2_get_ovector_pointer(pcre2_match_data *match_data); +

+

+In general, a pattern matches a certain portion of the subject, and in +addition, further substrings from the subject may be picked out by +parenthesized parts of the pattern. Following the usage in Jeffrey Friedl's +book, this is called "capturing" in what follows, and the phrase "capture +group" (Perl terminology) is used for a fragment of a pattern that picks out a +substring. PCRE2 supports several other kinds of parenthesized group that do +not cause substrings to be captured. The pcre2_pattern_info() function +can be used to find out how many capture groups there are in a compiled +pattern. +

+

+You can use auxiliary functions for accessing captured substrings +by number +or +by name, +as described in sections below. +

+

+Alternatively, you can make direct use of the vector of PCRE2_SIZE values, +called the ovector, which contains the offsets of captured strings. It is +part of the +match data block. +The function pcre2_get_ovector_pointer() returns the address of the +ovector, and pcre2_get_ovector_count() returns the number of pairs of +values it contains. +

+

+Within the ovector, the first in each pair of values is set to the offset of +the first code unit of a substring, and the second is set to the offset of the +first code unit after the end of a substring. These values are always code unit +offsets, not character offsets. That is, they are byte offsets in the 8-bit +library, 16-bit offsets in the 16-bit library, and 32-bit offsets in the 32-bit +library. +

+

+After a partial match (error return PCRE2_ERROR_PARTIAL), only the first pair +of offsets (that is, ovector[0] and ovector[1]) are set. They +identify the part of the subject that was partially matched. See the +pcre2partial +documentation for details of partial matching. +

+

+After a fully successful match, the first pair of offsets identifies the +portion of the subject string that was matched by the entire pattern. The next +pair is used for the first captured substring, and so on. The value returned by +pcre2_match() is one more than the highest numbered pair that has been +set. For example, if two substrings have been captured, the returned value is +3. If there are no captured substrings, the return value from a successful +match is 1, indicating that just the first pair of offsets has been set. +

+

+If a pattern uses the \K escape sequence within a positive assertion, the +reported start of a successful match can be greater than the end of the match. +For example, if the pattern (?=ab\K) is matched against "ab", the start and +end offset values for the match are 2 and 0. +

+

+If a capture group is matched repeatedly within a single match operation, it is +the last portion of the subject that it matched that is returned. +

+

+If the ovector is too small to hold all the captured substring offsets, as much +as possible is filled in, and the function returns a value of zero. If captured +substrings are not of interest, pcre2_match() may be called with a match +data block whose ovector is of minimum length (that is, one pair). +

+

+It is possible for capture group number n+1 to match some part of the +subject when group n has not been used at all. For example, if the string +"abc" is matched against the pattern (a|(z))(bc) the return from the function +is 4, and groups 1 and 3 are matched, but 2 is not. When this happens, both +values in the offset pairs corresponding to unused groups are set to +PCRE2_UNSET. +

+

+Offset values that correspond to unused groups at the end of the expression are +also set to PCRE2_UNSET. For example, if the string "abc" is matched against +the pattern (abc)(x(yz)?)? groups 2 and 3 are not matched. The return from the +function is 2, because the highest used capture group number is 1. The offsets +for the second and third capture groups (assuming the vector is large enough, +of course) are set to PCRE2_UNSET. +

+

+Elements in the ovector that do not correspond to capturing parentheses in the +pattern are never changed. That is, if a pattern contains n capturing +parentheses, no more than ovector[0] to ovector[2n+1] are set by +pcre2_match(). The other elements retain whatever values they previously +had. After a failed match attempt, the contents of the ovector are unchanged. +

+
OTHER INFORMATION ABOUT A MATCH
+

+PCRE2_SPTR pcre2_get_mark(pcre2_match_data *match_data); +
+
+PCRE2_SIZE pcre2_get_startchar(pcre2_match_data *match_data); +

+

+As well as the offsets in the ovector, other information about a match is +retained in the match data block and can be retrieved by the above functions in +appropriate circumstances. If they are called at other times, the result is +undefined. +

+

+After a successful match, a partial match (PCRE2_ERROR_PARTIAL), or a failure +to match (PCRE2_ERROR_NOMATCH), a mark name may be available. The function +pcre2_get_mark() can be called to access this name, which can be +specified in the pattern by any of the backtracking control verbs, not just +(*MARK). The same function applies to all the verbs. It returns a pointer to +the zero-terminated name, which is within the compiled pattern. If no name is +available, NULL is returned. The length of the name (excluding the terminating +zero) is stored in the code unit that precedes the name. You should use this +length instead of relying on the terminating zero if the name might contain a +binary zero. +

+

+After a successful match, the name that is returned is the last mark name +encountered on the matching path through the pattern. Instances of backtracking +verbs without names do not count. Thus, for example, if the matching path +contains (*MARK:A)(*PRUNE), the name "A" is returned. After a "no match" or a +partial match, the last encountered name is returned. For example, consider +this pattern: +

+  ^(*MARK:A)((*MARK:B)a|b)c
+
+When it matches "bc", the returned name is A. The B mark is "seen" in the first +branch of the group, but it is not on the matching path. On the other hand, +when this pattern fails to match "bx", the returned name is B. +

+

+Warning: By default, certain start-of-match optimizations are used to +give a fast "no match" result in some situations. For example, if the anchoring +is removed from the pattern above, there is an initial check for the presence +of "c" in the subject before running the matching engine. This check fails for +"bx", causing a match failure without seeing any marks. You can disable the +start-of-match optimizations by setting the PCRE2_NO_START_OPTIMIZE option for +pcre2_compile() or by starting the pattern with (*NO_START_OPT). +

+

+After a successful match, a partial match, or one of the invalid UTF errors +(for example, PCRE2_ERROR_UTF8_ERR5), pcre2_get_startchar() can be +called. After a successful or partial match it returns the code unit offset of +the character at which the match started. For a non-partial match, this can be +different to the value of ovector[0] if the pattern contains the \K +escape sequence. After a partial match, however, this value is always the same +as ovector[0] because \K does not affect the result of a partial match. +

+

+After a UTF check failure, pcre2_get_startchar() can be used to obtain +the code unit offset of the invalid UTF character. Details are given in the +pcre2unicode +page. +

+
ERROR RETURNS FROM pcre2_match()
+

+If pcre2_match() fails, it returns a negative number. This can be +converted to a text string by calling the pcre2_get_error_message() +function (see "Obtaining a textual error message" +below). +Negative error codes are also returned by other functions, and are documented +with them. The codes are given names in the header file. If UTF checking is in +force and an invalid UTF subject string is detected, one of a number of +UTF-specific negative error codes is returned. Details are given in the +pcre2unicode +page. The following are the other errors that may be returned by +pcre2_match(): +

+  PCRE2_ERROR_NOMATCH
+
+The subject string did not match the pattern. +
+  PCRE2_ERROR_PARTIAL
+
+The subject string did not match, but it did match partially. See the +pcre2partial +documentation for details of partial matching. +
+  PCRE2_ERROR_BADMAGIC
+
+PCRE2 stores a 4-byte "magic number" at the start of the compiled code, to +catch the case when it is passed a junk pointer. This is the error that is +returned when the magic number is not present. +
+  PCRE2_ERROR_BADMODE
+
+This error is given when a compiled pattern is passed to a function in a +library of a different code unit width, for example, a pattern compiled by +the 8-bit library is passed to a 16-bit or 32-bit library function. +
+  PCRE2_ERROR_BADOFFSET
+
+The value of startoffset was greater than the length of the subject. +
+  PCRE2_ERROR_BADOPTION
+
+An unrecognized bit was set in the options argument. +
+  PCRE2_ERROR_BADUTFOFFSET
+
+The UTF code unit sequence that was passed as a subject was checked and found +to be valid (the PCRE2_NO_UTF_CHECK option was not set), but the value of +startoffset did not point to the beginning of a UTF character or the end +of the subject. +
+  PCRE2_ERROR_CALLOUT
+
+This error is never generated by pcre2_match() itself. It is provided for +use by callout functions that want to cause pcre2_match() or +pcre2_callout_enumerate() to return a distinctive error code. See the +pcre2callout +documentation for details. +
+  PCRE2_ERROR_DEPTHLIMIT
+
+The nested backtracking depth limit was reached. +
+  PCRE2_ERROR_HEAPLIMIT
+
+The heap limit was reached. +
+  PCRE2_ERROR_INTERNAL
+
+An unexpected internal error has occurred. This error could be caused by a bug +in PCRE2 or by overwriting of the compiled pattern. +
+  PCRE2_ERROR_JIT_STACKLIMIT
+
+This error is returned when a pattern that was successfully studied using JIT +is being matched, but the memory available for the just-in-time processing +stack is not large enough. See the +pcre2jit +documentation for more details. +
+  PCRE2_ERROR_MATCHLIMIT
+
+The backtracking match limit was reached. +
+  PCRE2_ERROR_NOMEMORY
+
+Heap memory is used to remember backtracking points. This error is given when +the memory allocation function (default or custom) fails. Note that a different +error, PCRE2_ERROR_HEAPLIMIT, is given if the amount of memory needed exceeds +the heap limit. PCRE2_ERROR_NOMEMORY is also returned if +PCRE2_COPY_MATCHED_SUBJECT is set and memory allocation fails. +
+  PCRE2_ERROR_NULL
+
+Either the code, subject, or match_data argument was passed +as NULL. +
+  PCRE2_ERROR_RECURSELOOP
+
+This error is returned when pcre2_match() detects a recursion loop within +the pattern. Specifically, it means that either the whole pattern or a +capture group has been called recursively for the second time at the same +position in the subject string. Some simple patterns that might do this are +detected and faulted at compile time, but more complicated cases, in particular +mutual recursions between two different groups, cannot be detected until +matching is attempted. +

+
OBTAINING A TEXTUAL ERROR MESSAGE
+

+int pcre2_get_error_message(int errorcode, PCRE2_UCHAR *buffer, + PCRE2_SIZE bufflen); +

+

+A text message for an error code from any PCRE2 function (compile, match, or +auxiliary) can be obtained by calling pcre2_get_error_message(). The code +is passed as the first argument, with the remaining two arguments specifying a +code unit buffer and its length in code units, into which the text message is +placed. The message is returned in code units of the appropriate width for the +library that is being used. +

+

+The returned message is terminated with a trailing zero, and the function +returns the number of code units used, excluding the trailing zero. If the +error number is unknown, the negative error code PCRE2_ERROR_BADDATA is +returned. If the buffer is too small, the message is truncated (but still with +a trailing zero), and the negative error code PCRE2_ERROR_NOMEMORY is returned. +None of the messages are very long; a buffer size of 120 code units is ample. +

+
EXTRACTING CAPTURED SUBSTRINGS BY NUMBER
+

+int pcre2_substring_length_bynumber(pcre2_match_data *match_data, + uint32_t number, PCRE2_SIZE *length); +
+
+int pcre2_substring_copy_bynumber(pcre2_match_data *match_data, + uint32_t number, PCRE2_UCHAR *buffer, + PCRE2_SIZE *bufflen); +
+
+int pcre2_substring_get_bynumber(pcre2_match_data *match_data, + uint32_t number, PCRE2_UCHAR **bufferptr, + PCRE2_SIZE *bufflen); +
+
+void pcre2_substring_free(PCRE2_UCHAR *buffer); +

+

+Captured substrings can be accessed directly by using the ovector as described +above. +For convenience, auxiliary functions are provided for extracting captured +substrings as new, separate, zero-terminated strings. A substring that contains +a binary zero is correctly extracted and has a further zero added on the end, +but the result is not, of course, a C string. +

+

+The functions in this section identify substrings by number. The number zero +refers to the entire matched substring, with higher numbers referring to +substrings captured by parenthesized groups. After a partial match, only +substring zero is available. An attempt to extract any other substring gives +the error PCRE2_ERROR_PARTIAL. The next section describes similar functions for +extracting captured substrings by name. +

+

+If a pattern uses the \K escape sequence within a positive assertion, the +reported start of a successful match can be greater than the end of the match. +For example, if the pattern (?=ab\K) is matched against "ab", the start and +end offset values for the match are 2 and 0. In this situation, calling these +functions with a zero substring number extracts a zero-length empty string. +

+

+You can find the length in code units of a captured substring without +extracting it by calling pcre2_substring_length_bynumber(). The first +argument is a pointer to the match data block, the second is the group number, +and the third is a pointer to a variable into which the length is placed. If +you just want to know whether or not the substring has been captured, you can +pass the third argument as NULL. +

+

+The pcre2_substring_copy_bynumber() function copies a captured substring +into a supplied buffer, whereas pcre2_substring_get_bynumber() copies it +into new memory, obtained using the same memory allocation function that was +used for the match data block. The first two arguments of these functions are a +pointer to the match data block and a capture group number. +

+

+The final arguments of pcre2_substring_copy_bynumber() are a pointer to +the buffer and a pointer to a variable that contains its length in code units. +This is updated to contain the actual number of code units used for the +extracted substring, excluding the terminating zero. +

+

+For pcre2_substring_get_bynumber() the third and fourth arguments point +to variables that are updated with a pointer to the new memory and the number +of code units that comprise the substring, again excluding the terminating +zero. When the substring is no longer needed, the memory should be freed by +calling pcre2_substring_free(). +

+

+The return value from all these functions is zero for success, or a negative +error code. If the pattern match failed, the match failure code is returned. +If a substring number greater than zero is used after a partial match, +PCRE2_ERROR_PARTIAL is returned. Other possible error codes are: +

+  PCRE2_ERROR_NOMEMORY
+
+The buffer was too small for pcre2_substring_copy_bynumber(), or the +attempt to get memory failed for pcre2_substring_get_bynumber(). +
+  PCRE2_ERROR_NOSUBSTRING
+
+There is no substring with that number in the pattern, that is, the number is +greater than the number of capturing parentheses. +
+  PCRE2_ERROR_UNAVAILABLE
+
+The substring number, though not greater than the number of captures in the +pattern, is greater than the number of slots in the ovector, so the substring +could not be captured. +
+  PCRE2_ERROR_UNSET
+
+The substring did not participate in the match. For example, if the pattern is +(abc)|(def) and the subject is "def", and the ovector contains at least two +capturing slots, substring number 1 is unset. +

+
EXTRACTING A LIST OF ALL CAPTURED SUBSTRINGS
+

+int pcre2_substring_list_get(pcre2_match_data *match_data, +" PCRE2_UCHAR ***listptr, PCRE2_SIZE **lengthsptr); +
+
+void pcre2_substring_list_free(PCRE2_UCHAR **list); +

+

+The pcre2_substring_list_get() function extracts all available substrings +and builds a list of pointers to them. It also (optionally) builds a second +list that contains their lengths (in code units), excluding a terminating zero +that is added to each of them. All this is done in a single block of memory +that is obtained using the same memory allocation function that was used to get +the match data block. +

+

+This function must be called only after a successful match. If called after a +partial match, the error code PCRE2_ERROR_PARTIAL is returned. +

+

+The address of the memory block is returned via listptr, which is also +the start of the list of string pointers. The end of the list is marked by a +NULL pointer. The address of the list of lengths is returned via +lengthsptr. If your strings do not contain binary zeros and you do not +therefore need the lengths, you may supply NULL as the lengthsptr +argument to disable the creation of a list of lengths. The yield of the +function is zero if all went well, or PCRE2_ERROR_NOMEMORY if the memory block +could not be obtained. When the list is no longer needed, it should be freed by +calling pcre2_substring_list_free(). +

+

+If this function encounters a substring that is unset, which can happen when +capture group number n+1 matches some part of the subject, but group +n has not been used at all, it returns an empty string. This can be +distinguished from a genuine zero-length substring by inspecting the +appropriate offset in the ovector, which contain PCRE2_UNSET for unset +substrings, or by calling pcre2_substring_length_bynumber(). +

+
EXTRACTING CAPTURED SUBSTRINGS BY NAME
+

+int pcre2_substring_number_from_name(const pcre2_code *code, + PCRE2_SPTR name); +
+
+int pcre2_substring_length_byname(pcre2_match_data *match_data, + PCRE2_SPTR name, PCRE2_SIZE *length); +
+
+int pcre2_substring_copy_byname(pcre2_match_data *match_data, + PCRE2_SPTR name, PCRE2_UCHAR *buffer, PCRE2_SIZE *bufflen); +
+
+int pcre2_substring_get_byname(pcre2_match_data *match_data, + PCRE2_SPTR name, PCRE2_UCHAR **bufferptr, PCRE2_SIZE *bufflen); +
+
+void pcre2_substring_free(PCRE2_UCHAR *buffer); +

+

+To extract a substring by name, you first have to find associated number. +For example, for this pattern: +

+  (a+)b(?<xxx>\d+)...
+
+the number of the capture group called "xxx" is 2. If the name is known to be +unique (PCRE2_DUPNAMES was not set), you can find the number from the name by +calling pcre2_substring_number_from_name(). The first argument is the +compiled pattern, and the second is the name. The yield of the function is the +group number, PCRE2_ERROR_NOSUBSTRING if there is no group with that name, or +PCRE2_ERROR_NOUNIQUESUBSTRING if there is more than one group with that name. +Given the number, you can extract the substring directly from the ovector, or +use one of the "bynumber" functions described above. +

+

+For convenience, there are also "byname" functions that correspond to the +"bynumber" functions, the only difference being that the second argument is a +name instead of a number. If PCRE2_DUPNAMES is set and there are duplicate +names, these functions scan all the groups with the given name, and return the +captured substring from the first named group that is set. +

+

+If there are no groups with the given name, PCRE2_ERROR_NOSUBSTRING is +returned. If all groups with the name have numbers that are greater than the +number of slots in the ovector, PCRE2_ERROR_UNAVAILABLE is returned. If there +is at least one group with a slot in the ovector, but no group is found to be +set, PCRE2_ERROR_UNSET is returned. +

+

+Warning: If the pattern uses the (?| feature to set up multiple +capture groups with the same number, as described in the +section on duplicate group numbers +in the +pcre2pattern +page, you cannot use names to distinguish the different capture groups, because +names are not included in the compiled code. The matching process uses only +numbers. For this reason, the use of different names for groups with the +same number causes an error at compile time. +

+
CREATING A NEW STRING WITH SUBSTITUTIONS
+

+int pcre2_substitute(const pcre2_code *code, PCRE2_SPTR subject, + PCRE2_SIZE length, PCRE2_SIZE startoffset, + uint32_t options, pcre2_match_data *match_data, + pcre2_match_context *mcontext, PCRE2_SPTR replacement, + PCRE2_SIZE rlength, PCRE2_UCHAR *outputbuffer, + PCRE2_SIZE *outlengthptr); +

+

+This function optionally calls pcre2_match() and then makes a copy of the +subject string in outputbuffer, replacing parts that were matched with +the replacement string, whose length is supplied in rlength, which +can be given as PCRE2_ZERO_TERMINATED for a zero-terminated string. As a +special case, if replacement is NULL and rlength is zero, the +replacement is assumed to be an empty string. If rlength is non-zero, an +error occurs if replacement is NULL. +

+

+There is an option (see PCRE2_SUBSTITUTE_REPLACEMENT_ONLY below) to return just +the replacement string(s). The default action is to perform just one +replacement if the pattern matches, but there is an option that requests +multiple replacements (see PCRE2_SUBSTITUTE_GLOBAL below). +

+

+If successful, pcre2_substitute() returns the number of substitutions +that were carried out. This may be zero if no match was found, and is never +greater than one unless PCRE2_SUBSTITUTE_GLOBAL is set. A negative value is +returned if an error is detected. +

+

+Matches in which a \K item in a lookahead in the pattern causes the match to +end before it starts are not supported, and give rise to an error return. For +global replacements, matches in which \K in a lookbehind causes the match to +start earlier than the point that was reached in the previous iteration are +also not supported. +

+

+The first seven arguments of pcre2_substitute() are the same as for +pcre2_match(), except that the partial matching options are not +permitted, and match_data may be passed as NULL, in which case a match +data block is obtained and freed within this function, using memory management +functions from the match context, if provided, or else those that were used to +allocate memory for the compiled code. +

+

+If match_data is not NULL and PCRE2_SUBSTITUTE_MATCHED is not set, the +provided block is used for all calls to pcre2_match(), and its contents +afterwards are the result of the final call. For global changes, this will +always be a no-match error. The contents of the ovector within the match data +block may or may not have been changed. +

+

+As well as the usual options for pcre2_match(), a number of additional +options can be set in the options argument of pcre2_substitute(). +One such option is PCRE2_SUBSTITUTE_MATCHED. When this is set, an external +match_data block must be provided, and it must have already been used for +an external call to pcre2_match() with the same pattern and subject +arguments. The data in the match_data block (return code, offset vector) +is then used for the first substitution instead of calling pcre2_match() +from within pcre2_substitute(). This allows an application to check for a +match before choosing to substitute, without having to repeat the match. +

+

+The contents of the externally supplied match data block are not changed when +PCRE2_SUBSTITUTE_MATCHED is set. If PCRE2_SUBSTITUTE_GLOBAL is also set, +pcre2_match() is called after the first substitution to check for further +matches, but this is done using an internally obtained match data block, thus +always leaving the external block unchanged. +

+

+The code argument is not used for matching before the first substitution +when PCRE2_SUBSTITUTE_MATCHED is set, but it must be provided, even when +PCRE2_SUBSTITUTE_GLOBAL is not set, because it contains information such as the +UTF setting and the number of capturing parentheses in the pattern. +

+

+The default action of pcre2_substitute() is to return a copy of the +subject string with matched substrings replaced. However, if +PCRE2_SUBSTITUTE_REPLACEMENT_ONLY is set, only the replacement substrings are +returned. In the global case, multiple replacements are concatenated in the +output buffer. Substitution callouts (see +below) +can be used to separate them if necessary. +

+

+The outlengthptr argument of pcre2_substitute() must point to a +variable that contains the length, in code units, of the output buffer. If the +function is successful, the value is updated to contain the length in code +units of the new string, excluding the trailing zero that is automatically +added. +

+

+If the function is not successful, the value set via outlengthptr depends +on the type of error. For syntax errors in the replacement string, the value is +the offset in the replacement string where the error was detected. For other +errors, the value is PCRE2_UNSET by default. This includes the case of the +output buffer being too small, unless PCRE2_SUBSTITUTE_OVERFLOW_LENGTH is set. +

+

+PCRE2_SUBSTITUTE_OVERFLOW_LENGTH changes what happens when the output buffer is +too small. The default action is to return PCRE2_ERROR_NOMEMORY immediately. If +this option is set, however, pcre2_substitute() continues to go through +the motions of matching and substituting (without, of course, writing anything) +in order to compute the size of buffer that is needed. This value is passed +back via the outlengthptr variable, with the result of the function still +being PCRE2_ERROR_NOMEMORY. +

+

+Passing a buffer size of zero is a permitted way of finding out how much memory +is needed for given substitution. However, this does mean that the entire +operation is carried out twice. Depending on the application, it may be more +efficient to allocate a large buffer and free the excess afterwards, instead of +using PCRE2_SUBSTITUTE_OVERFLOW_LENGTH. +

+

+The replacement string, which is interpreted as a UTF string in UTF mode, is +checked for UTF validity unless PCRE2_NO_UTF_CHECK is set. An invalid UTF +replacement string causes an immediate return with the relevant UTF error code. +

+

+If PCRE2_SUBSTITUTE_LITERAL is set, the replacement string is not interpreted +in any way. By default, however, a dollar character is an escape character that +can specify the insertion of characters from capture groups and names from +(*MARK) or other control verbs in the pattern. Dollar is the only escape +character (backslash is treated as literal). The following forms are always +recognized: +

+  $$                  insert a dollar character
+  $<n> or ${<n>}      insert the contents of group <n>
+  $*MARK or ${*MARK}  insert a control verb name
+
+Either a group number or a group name can be given for <n>. Curly brackets are +required only if the following character would be interpreted as part of the +number or name. The number may be zero to include the entire matched string. +For example, if the pattern a(b)c is matched with "=abc=" and the replacement +string "+$1$0$1+", the result is "=+babcb+=". +

+

+$*MARK inserts the name from the last encountered backtracking control verb on +the matching path that has a name. (*MARK) must always include a name, but the +other verbs need not. For example, in the case of (*MARK:A)(*PRUNE) the name +inserted is "A", but for (*MARK:A)(*PRUNE:B) the relevant name is "B". This +facility can be used to perform simple simultaneous substitutions, as this +pcre2test example shows: +

+  /(*MARK:pear)apple|(*MARK:orange)lemon/g,replace=${*MARK}
+      apple lemon
+   2: pear orange
+
+PCRE2_SUBSTITUTE_GLOBAL causes the function to iterate over the subject string, +replacing every matching substring. If this option is not set, only the first +matching substring is replaced. The search for matches takes place in the +original subject string (that is, previous replacements do not affect it). +Iteration is implemented by advancing the startoffset value for each +search, which is always passed the entire subject string. If an offset limit is +set in the match context, searching stops when that limit is reached. +

+

+You can restrict the effect of a global substitution to a portion of the +subject string by setting either or both of startoffset and an offset +limit. Here is a pcre2test example: +

+  /B/g,replace=!,use_offset_limit
+  ABC ABC ABC ABC\=offset=3,offset_limit=12
+   2: ABC A!C A!C ABC
+
+When continuing with global substitutions after matching a substring with zero +length, an attempt to find a non-empty match at the same offset is performed. +If this is not successful, the offset is advanced by one character except when +CRLF is a valid newline sequence and the next two characters are CR, LF. In +this case, the offset is advanced by two characters. +

+

+PCRE2_SUBSTITUTE_UNKNOWN_UNSET causes references to capture groups that do +not appear in the pattern to be treated as unset groups. This option should be +used with care, because it means that a typo in a group name or number no +longer causes the PCRE2_ERROR_NOSUBSTRING error. +

+

+PCRE2_SUBSTITUTE_UNSET_EMPTY causes unset capture groups (including unknown +groups when PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set) to be treated as empty +strings when inserted as described above. If this option is not set, an attempt +to insert an unset group causes the PCRE2_ERROR_UNSET error. This option does +not influence the extended substitution syntax described below. +

+

+PCRE2_SUBSTITUTE_EXTENDED causes extra processing to be applied to the +replacement string. Without this option, only the dollar character is special, +and only the group insertion forms listed above are valid. When +PCRE2_SUBSTITUTE_EXTENDED is set, two things change: +

+

+Firstly, backslash in a replacement string is interpreted as an escape +character. The usual forms such as \n or \x{ddd} can be used to specify +particular character codes, and backslash followed by any non-alphanumeric +character quotes that character. Extended quoting can be coded using \Q...\E, +exactly as in pattern strings. +

+

+There are also four escape sequences for forcing the case of inserted letters. +The insertion mechanism has three states: no case forcing, force upper case, +and force lower case. The escape sequences change the current state: \U and +\L change to upper or lower case forcing, respectively, and \E (when not +terminating a \Q quoted sequence) reverts to no case forcing. The sequences +\u and \l force the next character (if it is a letter) to upper or lower +case, respectively, and then the state automatically reverts to no case +forcing. Case forcing applies to all inserted characters, including those from +capture groups and letters within \Q...\E quoted sequences. If either +PCRE2_UTF or PCRE2_UCP was set when the pattern was compiled, Unicode +properties are used for case forcing characters whose code points are greater +than 127. +

+

+Note that case forcing sequences such as \U...\E do not nest. For example, +the result of processing "\Uaa\LBB\Ecc\E" is "AAbbcc"; the final \E has no +effect. Note also that the PCRE2_ALT_BSUX and PCRE2_EXTRA_ALT_BSUX options do +not apply to replacement strings. +

+

+The second effect of setting PCRE2_SUBSTITUTE_EXTENDED is to add more +flexibility to capture group substitution. The syntax is similar to that used +by Bash: +

+  ${<n>:-<string>}
+  ${<n>:+<string1>:<string2>}
+
+As before, <n> may be a group number or a name. The first form specifies a +default value. If group <n> is set, its value is inserted; if not, <string> is +expanded and the result inserted. The second form specifies strings that are +expanded and inserted when group <n> is set or unset, respectively. The first +form is just a convenient shorthand for +
+  ${<n>:+${<n>}:<string>}
+
+Backslash can be used to escape colons and closing curly brackets in the +replacement strings. A change of the case forcing state within a replacement +string remains in force afterwards, as shown in this pcre2test example: +
+  /(some)?(body)/substitute_extended,replace=${1:+\U:\L}HeLLo
+      body
+   1: hello
+      somebody
+   1: HELLO
+
+The PCRE2_SUBSTITUTE_UNSET_EMPTY option does not affect these extended +substitutions. However, PCRE2_SUBSTITUTE_UNKNOWN_UNSET does cause unknown +groups in the extended syntax forms to be treated as unset. +

+

+If PCRE2_SUBSTITUTE_LITERAL is set, PCRE2_SUBSTITUTE_UNKNOWN_UNSET, +PCRE2_SUBSTITUTE_UNSET_EMPTY, and PCRE2_SUBSTITUTE_EXTENDED are irrelevant and +are ignored. +

+
+Substitution errors +
+

+In the event of an error, pcre2_substitute() returns a negative error +code. Except for PCRE2_ERROR_NOMATCH (which is never returned), errors from +pcre2_match() are passed straight back. +

+

+PCRE2_ERROR_NOSUBSTRING is returned for a non-existent substring insertion, +unless PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set. +

+

+PCRE2_ERROR_UNSET is returned for an unset substring insertion (including an +unknown substring when PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set) when the simple +(non-extended) syntax is used and PCRE2_SUBSTITUTE_UNSET_EMPTY is not set. +

+

+PCRE2_ERROR_NOMEMORY is returned if the output buffer is not big enough. If the +PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option is set, the size of buffer that is +needed is returned via outlengthptr. Note that this does not happen by +default. +

+

+PCRE2_ERROR_NULL is returned if PCRE2_SUBSTITUTE_MATCHED is set but the +match_data argument is NULL or if the subject or replacement +arguments are NULL. For backward compatibility reasons an exception is made for +the replacement argument if the rlength argument is also 0. +

+

+PCRE2_ERROR_BADREPLACEMENT is used for miscellaneous syntax errors in the +replacement string, with more particular errors being PCRE2_ERROR_BADREPESCAPE +(invalid escape sequence), PCRE2_ERROR_REPMISSINGBRACE (closing curly bracket +not found), PCRE2_ERROR_BADSUBSTITUTION (syntax error in extended group +substitution), and PCRE2_ERROR_BADSUBSPATTERN (the pattern match ended before +it started or the match started earlier than the current position in the +subject, which can happen if \K is used in an assertion). +

+

+As for all PCRE2 errors, a text message that describes the error can be +obtained by calling the pcre2_get_error_message() function (see +"Obtaining a textual error message" +above). +

+
+Substitution callouts +
+

+int pcre2_set_substitute_callout(pcre2_match_context *mcontext, + int (*callout_function)(pcre2_substitute_callout_block *, void *), + void *callout_data); +
+
+The pcre2_set_substitution_callout() function can be used to specify a +callout function for pcre2_substitute(). This information is passed in +a match context. The callout function is called after each substitution has +been processed, but it can cause the replacement not to happen. The callout +function is not called for simulated substitutions that happen as a result of +the PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option. +

+

+The first argument of the callout function is a pointer to a substitute callout +block structure, which contains the following fields, not necessarily in this +order: +

+  uint32_t    version;
+  uint32_t    subscount;
+  PCRE2_SPTR  input;
+  PCRE2_SPTR  output;
+  PCRE2_SIZE *ovector;
+  uint32_t    oveccount;
+  PCRE2_SIZE  output_offsets[2];
+
+The version field contains the version number of the block format. The +current version is 0. The version number will increase in future if more fields +are added, but the intention is never to remove any of the existing fields. +

+

+The subscount field is the number of the current match. It is 1 for the +first callout, 2 for the second, and so on. The input and output +pointers are copies of the values passed to pcre2_substitute(). +

+

+The ovector field points to the ovector, which contains the result of the +most recent match. The oveccount field contains the number of pairs that +are set in the ovector, and is always greater than zero. +

+

+The output_offsets vector contains the offsets of the replacement in the +output string. This has already been processed for dollar and (if requested) +backslash substitutions as described above. +

+

+The second argument of the callout function is the value passed as +callout_data when the function was registered. The value returned by the +callout function is interpreted as follows: +

+

+If the value is zero, the replacement is accepted, and, if +PCRE2_SUBSTITUTE_GLOBAL is set, processing continues with a search for the next +match. If the value is not zero, the current replacement is not accepted. If +the value is greater than zero, processing continues when +PCRE2_SUBSTITUTE_GLOBAL is set. Otherwise (the value is less than zero or +PCRE2_SUBSTITUTE_GLOBAL is not set), the rest of the input is copied to the +output and the call to pcre2_substitute() exits, returning the number of +matches so far. +

+
DUPLICATE CAPTURE GROUP NAMES
+

+int pcre2_substring_nametable_scan(const pcre2_code *code, + PCRE2_SPTR name, PCRE2_SPTR *first, PCRE2_SPTR *last); +

+

+When a pattern is compiled with the PCRE2_DUPNAMES option, names for capture +groups are not required to be unique. Duplicate names are always allowed for +groups with the same number, created by using the (?| feature. Indeed, if such +groups are named, they are required to use the same names. +

+

+Normally, patterns that use duplicate names are such that in any one match, +only one of each set of identically-named groups participates. An example is +shown in the +pcre2pattern +documentation. +

+

+When duplicates are present, pcre2_substring_copy_byname() and +pcre2_substring_get_byname() return the first substring corresponding to +the given name that is set. Only if none are set is PCRE2_ERROR_UNSET is +returned. The pcre2_substring_number_from_name() function returns the +error PCRE2_ERROR_NOUNIQUESUBSTRING when there are duplicate names. +

+

+If you want to get full details of all captured substrings for a given name, +you must use the pcre2_substring_nametable_scan() function. The first +argument is the compiled pattern, and the second is the name. If the third and +fourth arguments are NULL, the function returns a group number for a unique +name, or PCRE2_ERROR_NOUNIQUESUBSTRING otherwise. +

+

+When the third and fourth arguments are not NULL, they must be pointers to +variables that are updated by the function. After it has run, they point to the +first and last entries in the name-to-number table for the given name, and the +function returns the length of each entry in code units. In both cases, +PCRE2_ERROR_NOSUBSTRING is returned if there are no entries for the given name. +

+

+The format of the name table is described +above +in the section entitled Information about a pattern. Given all the +relevant entries for the name, you can extract each of their numbers, and hence +the captured data. +

+
FINDING ALL POSSIBLE MATCHES AT ONE POSITION
+

+The traditional matching function uses a similar algorithm to Perl, which stops +when it finds the first match at a given point in the subject. If you want to +find all possible matches, or the longest possible match at a given position, +consider using the alternative matching function (see below) instead. If you +cannot use the alternative function, you can kludge it up by making use of the +callout facility, which is described in the +pcre2callout +documentation. +

+

+What you have to do is to insert a callout right at the end of the pattern. +When your callout function is called, extract and save the current matched +substring. Then return 1, which forces pcre2_match() to backtrack and try +other alternatives. Ultimately, when it runs out of matches, +pcre2_match() will yield PCRE2_ERROR_NOMATCH. +

+
MATCHING A PATTERN: THE ALTERNATIVE FUNCTION
+

+int pcre2_dfa_match(const pcre2_code *code, PCRE2_SPTR subject, + PCRE2_SIZE length, PCRE2_SIZE startoffset, + uint32_t options, pcre2_match_data *match_data, + pcre2_match_context *mcontext, + int *workspace, PCRE2_SIZE wscount); +

+

+The function pcre2_dfa_match() is called to match a subject string +against a compiled pattern, using a matching algorithm that scans the subject +string just once (not counting lookaround assertions), and does not backtrack +(except when processing lookaround assertions). This has different +characteristics to the normal algorithm, and is not compatible with Perl. Some +of the features of PCRE2 patterns are not supported. Nevertheless, there are +times when this kind of matching can be useful. For a discussion of the two +matching algorithms, and a list of features that pcre2_dfa_match() does +not support, see the +pcre2matching +documentation. +

+

+The arguments for the pcre2_dfa_match() function are the same as for +pcre2_match(), plus two extras. The ovector within the match data block +is used in a different way, and this is described below. The other common +arguments are used in the same way as for pcre2_match(), so their +description is not repeated here. +

+

+The two additional arguments provide workspace for the function. The workspace +vector should contain at least 20 elements. It is used for keeping track of +multiple paths through the pattern tree. More workspace is needed for patterns +and subjects where there are a lot of potential matches. +

+

+Here is an example of a simple call to pcre2_dfa_match(): +

+  int wspace[20];
+  pcre2_match_data *md = pcre2_match_data_create(4, NULL);
+  int rc = pcre2_dfa_match(
+    re,             /* result of pcre2_compile() */
+    "some string",  /* the subject string */
+    11,             /* the length of the subject string */
+    0,              /* start at offset 0 in the subject */
+    0,              /* default options */
+    md,             /* the match data block */
+    NULL,           /* a match context; NULL means use defaults */
+    wspace,         /* working space vector */
+    20);            /* number of elements (NOT size in bytes) */
+
+

+
+Option bits for pcre2_dfa_match() +
+

+The unused bits of the options argument for pcre2_dfa_match() must +be zero. The only bits that may be set are PCRE2_ANCHORED, +PCRE2_COPY_MATCHED_SUBJECT, PCRE2_ENDANCHORED, PCRE2_NOTBOL, PCRE2_NOTEOL, +PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART, PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD, +PCRE2_PARTIAL_SOFT, PCRE2_DFA_SHORTEST, and PCRE2_DFA_RESTART. All but the last +four of these are exactly the same as for pcre2_match(), so their +description is not repeated here. +

+  PCRE2_PARTIAL_HARD
+  PCRE2_PARTIAL_SOFT
+
+These have the same general effect as they do for pcre2_match(), but the +details are slightly different. When PCRE2_PARTIAL_HARD is set for +pcre2_dfa_match(), it returns PCRE2_ERROR_PARTIAL if the end of the +subject is reached and there is still at least one matching possibility that +requires additional characters. This happens even if some complete matches have +already been found. When PCRE2_PARTIAL_SOFT is set, the return code +PCRE2_ERROR_NOMATCH is converted into PCRE2_ERROR_PARTIAL if the end of the +subject is reached, there have been no complete matches, but there is still at +least one matching possibility. The portion of the string that was inspected +when the longest partial match was found is set as the first matching string in +both cases. There is a more detailed discussion of partial and multi-segment +matching, with examples, in the +pcre2partial +documentation. +
+  PCRE2_DFA_SHORTEST
+
+Setting the PCRE2_DFA_SHORTEST option causes the matching algorithm to stop as +soon as it has found one match. Because of the way the alternative algorithm +works, this is necessarily the shortest possible match at the first possible +matching point in the subject string. +
+  PCRE2_DFA_RESTART
+
+When pcre2_dfa_match() returns a partial match, it is possible to call it +again, with additional subject characters, and have it continue with the same +match. The PCRE2_DFA_RESTART option requests this action; when it is set, the +workspace and wscount options must reference the same vector as +before because data about the match so far is left in them after a partial +match. There is more discussion of this facility in the +pcre2partial +documentation. +

+
+Successful returns from pcre2_dfa_match() +
+

+When pcre2_dfa_match() succeeds, it may have matched more than one +substring in the subject. Note, however, that all the matches from one run of +the function start at the same point in the subject. The shorter matches are +all initial substrings of the longer matches. For example, if the pattern +

+  <.*>
+
+is matched against the string +
+  This is <something> <something else> <something further> no more
+
+the three matched strings are +
+  <something> <something else> <something further>
+  <something> <something else>
+  <something>
+
+On success, the yield of the function is a number greater than zero, which is +the number of matched substrings. The offsets of the substrings are returned in +the ovector, and can be extracted by number in the same way as for +pcre2_match(), but the numbers bear no relation to any capture groups +that may exist in the pattern, because DFA matching does not support capturing. +

+

+Calls to the convenience functions that extract substrings by name +return the error PCRE2_ERROR_DFA_UFUNC (unsupported function) if used after a +DFA match. The convenience functions that extract substrings by number never +return PCRE2_ERROR_NOSUBSTRING. +

+

+The matched strings are stored in the ovector in reverse order of length; that +is, the longest matching string is first. If there were too many matches to fit +into the ovector, the yield of the function is zero, and the vector is filled +with the longest matches. +

+

+NOTE: PCRE2's "auto-possessification" optimization usually applies to character +repeats at the end of a pattern (as well as internally). For example, the +pattern "a\d+" is compiled as if it were "a\d++". For DFA matching, this +means that only one possible match is found. If you really do want multiple +matches in such cases, either use an ungreedy repeat such as "a\d+?" or set +the PCRE2_NO_AUTO_POSSESS option when compiling. +

+
+Error returns from pcre2_dfa_match() +
+

+The pcre2_dfa_match() function returns a negative number when it fails. +Many of the errors are the same as for pcre2_match(), as described +above. +There are in addition the following errors that are specific to +pcre2_dfa_match(): +

+  PCRE2_ERROR_DFA_UITEM
+
+This return is given if pcre2_dfa_match() encounters an item in the +pattern that it does not support, for instance, the use of \C in a UTF mode or +a backreference. +
+  PCRE2_ERROR_DFA_UCOND
+
+This return is given if pcre2_dfa_match() encounters a condition item +that uses a backreference for the condition, or a test for recursion in a +specific capture group. These are not supported. +
+  PCRE2_ERROR_DFA_UINVALID_UTF
+
+This return is given if pcre2_dfa_match() is called for a pattern that +was compiled with PCRE2_MATCH_INVALID_UTF. This is not supported for DFA +matching. +
+  PCRE2_ERROR_DFA_WSSIZE
+
+This return is given if pcre2_dfa_match() runs out of space in the +workspace vector. +
+  PCRE2_ERROR_DFA_RECURSE
+
+When a recursion or subroutine call is processed, the matching function calls +itself recursively, using private memory for the ovector and workspace. +This error is given if the internal ovector is not large enough. This should be +extremely rare, as a vector of size 1000 is used. +
+  PCRE2_ERROR_DFA_BADRESTART
+
+When pcre2_dfa_match() is called with the PCRE2_DFA_RESTART option, +some plausibility checks are made on the contents of the workspace, which +should contain data about the previous partial match. If any of these checks +fail, this error is given. +

BUILDING PCRE2
+

+PCRE2 is distributed with a configure script that can be used to build +the library in Unix-like environments using the applications known as +Autotools. Also in the distribution are files to support building using +CMake instead of configure. The text file +README +contains general information about building with Autotools (some of which is +repeated below), and also has some comments about building on various operating +systems. The files in the vms directory support building under OpenVMS. +There is a lot more information about building PCRE2 without using +Autotools (including information about using CMake and building "by +hand") in the text file called +NON-AUTOTOOLS-BUILD. +You should consult this file as well as the +README +file if you are building in a non-Unix-like environment. +

+
PCRE2 BUILD-TIME OPTIONS
+

+The rest of this document describes the optional features of PCRE2 that can be +selected when the library is compiled. It assumes use of the configure +script, where the optional features are selected or deselected by providing +options to configure before running the make command. However, the +same options can be selected in both Unix-like and non-Unix-like environments +if you are using CMake instead of configure to build PCRE2. +

+

+If you are not using Autotools or CMake, option selection can be done by +editing the config.h file, or by passing parameter settings to the +compiler, as described in +NON-AUTOTOOLS-BUILD. +

+

+The complete list of options for configure (which includes the standard +ones such as the selection of the installation directory) can be obtained by +running +

+  ./configure --help
+
+The following sections include descriptions of "on/off" options whose names +begin with --enable or --disable. Because of the way that configure +works, --enable and --disable always come in pairs, so the complementary option +always exists as well, but as it specifies the default, it is not described. +Options that specify values have names that start with --with. At the end of a +configure run, a summary of the configuration is output. +

+
BUILDING 8-BIT, 16-BIT AND 32-BIT LIBRARIES
+

+By default, a library called libpcre2-8 is built, containing functions +that take string arguments contained in arrays of bytes, interpreted either as +single-byte characters, or UTF-8 strings. You can also build two other +libraries, called libpcre2-16 and libpcre2-32, which process +strings that are contained in arrays of 16-bit and 32-bit code units, +respectively. These can be interpreted either as single-unit characters or +UTF-16/UTF-32 strings. To build these additional libraries, add one or both of +the following to the configure command: +

+  --enable-pcre2-16
+  --enable-pcre2-32
+
+If you do not want the 8-bit library, add +
+  --disable-pcre2-8
+
+as well. At least one of the three libraries must be built. Note that the POSIX +wrapper is for the 8-bit library only, and that pcre2grep is an 8-bit +program. Neither of these are built if you select only the 16-bit or 32-bit +libraries. +

+
BUILDING SHARED AND STATIC LIBRARIES
+

+The Autotools PCRE2 building process uses libtool to build both shared +and static libraries by default. You can suppress an unwanted library by adding +one of +

+  --disable-shared
+  --disable-static
+
+to the configure command. Setting --disable-shared ensures that PCRE2 +libraries are built as static libraries. The binaries that are then created as +part of the build process (for example, pcre2test and pcre2grep) +are linked statically with one or more PCRE2 libraries, but may also be +dynamically linked with other libraries such as libc. If you want these +binaries to be fully statically linked, you can set LDFLAGS like this: +
+
+LDFLAGS=--static ./configure --disable-shared +
+
+Note the two hyphens in --static. Of course, this works only if static versions +of all the relevant libraries are available for linking. +

+
UNICODE AND UTF SUPPORT
+

+By default, PCRE2 is built with support for Unicode and UTF character strings. +To build it without Unicode support, add +

+  --disable-unicode
+
+to the configure command. This setting applies to all three libraries. It +is not possible to build one library with Unicode support and another without +in the same configuration. +

+

+Of itself, Unicode support does not make PCRE2 treat strings as UTF-8, UTF-16 +or UTF-32. To do that, applications that use the library can set the PCRE2_UTF +option when they call pcre2_compile() to compile a pattern. +Alternatively, patterns may be started with (*UTF) unless the application has +locked this out by setting PCRE2_NEVER_UTF. +

+

+UTF support allows the libraries to process character code points up to +0x10ffff in the strings that they handle. Unicode support also gives access to +the Unicode properties of characters, using pattern escapes such as \P, \p, +and \X. Only the general category properties such as Lu and Nd, +script names, and some bi-directional properties are supported. Details are +given in the +pcre2pattern +documentation. +

+

+Pattern escapes such as \d and \w do not by default make use of Unicode +properties. The application can request that they do by setting the PCRE2_UCP +option. Unless the application has set PCRE2_NEVER_UCP, a pattern may also +request this by starting with (*UCP). +

+
DISABLING THE USE OF \C
+

+The \C escape sequence, which matches a single code unit, even in a UTF mode, +can cause unpredictable behaviour because it may leave the current matching +point in the middle of a multi-code-unit character. The application can lock it +out by setting the PCRE2_NEVER_BACKSLASH_C option when calling +pcre2_compile(). There is also a build-time option +

+  --enable-never-backslash-C
+
+(note the upper case C) which locks out the use of \C entirely. +

+
JUST-IN-TIME COMPILER SUPPORT
+

+Just-in-time (JIT) compiler support is included in the build by specifying +

+  --enable-jit
+
+This support is available only for certain hardware architectures. If this +option is set for an unsupported architecture, a building error occurs. +If in doubt, use +
+  --enable-jit=auto
+
+which enables JIT only if the current hardware is supported. You can check +if JIT is enabled in the configuration summary that is output at the end of a +configure run. If you are enabling JIT under SELinux you may also want to +add +
+  --enable-jit-sealloc
+
+which enables the use of an execmem allocator in JIT that is compatible with +SELinux. This has no effect if JIT is not enabled. See the +pcre2jit +documentation for a discussion of JIT usage. When JIT support is enabled, +pcre2grep automatically makes use of it, unless you add +
+  --disable-pcre2grep-jit
+
+to the configure command. +

+
NEWLINE RECOGNITION
+

+By default, PCRE2 interprets the linefeed (LF) character as indicating the end +of a line. This is the normal newline character on Unix-like systems. You can +compile PCRE2 to use carriage return (CR) instead, by adding +

+  --enable-newline-is-cr
+
+to the configure command. There is also an --enable-newline-is-lf option, +which explicitly specifies linefeed as the newline character. +

+

+Alternatively, you can specify that line endings are to be indicated by the +two-character sequence CRLF (CR immediately followed by LF). If you want this, +add +

+  --enable-newline-is-crlf
+
+to the configure command. There is a fourth option, specified by +
+  --enable-newline-is-anycrlf
+
+which causes PCRE2 to recognize any of the three sequences CR, LF, or CRLF as +indicating a line ending. A fifth option, specified by +
+  --enable-newline-is-any
+
+causes PCRE2 to recognize any Unicode newline sequence. The Unicode newline +sequences are the three just mentioned, plus the single characters VT (vertical +tab, U+000B), FF (form feed, U+000C), NEL (next line, U+0085), LS (line +separator, U+2028), and PS (paragraph separator, U+2029). The final option is +
+  --enable-newline-is-nul
+
+which causes NUL (binary zero) to be set as the default line-ending character. +

+

+Whatever default line ending convention is selected when PCRE2 is built can be +overridden by applications that use the library. At build time it is +recommended to use the standard for your operating system. +

+
WHAT \R MATCHES
+

+By default, the sequence \R in a pattern matches any Unicode newline sequence, +independently of what has been selected as the line ending sequence. If you +specify +

+  --enable-bsr-anycrlf
+
+the default is changed so that \R matches only CR, LF, or CRLF. Whatever is +selected when PCRE2 is built can be overridden by applications that use the +library. +

+
HANDLING VERY LARGE PATTERNS
+

+Within a compiled pattern, offset values are used to point from one part to +another (for example, from an opening parenthesis to an alternation +metacharacter). By default, in the 8-bit and 16-bit libraries, two-byte values +are used for these offsets, leading to a maximum size for a compiled pattern of +around 64 thousand code units. This is sufficient to handle all but the most +gigantic patterns. Nevertheless, some people do want to process truly enormous +patterns, so it is possible to compile PCRE2 to use three-byte or four-byte +offsets by adding a setting such as +

+  --with-link-size=3
+
+to the configure command. The value given must be 2, 3, or 4. For the +16-bit library, a value of 3 is rounded up to 4. In these libraries, using +longer offsets slows down the operation of PCRE2 because it has to load +additional data when handling them. For the 32-bit library the value is always +4 and cannot be overridden; the value of --with-link-size is ignored. +

+
LIMITING PCRE2 RESOURCE USAGE
+

+The pcre2_match() function increments a counter each time it goes round +its main loop. Putting a limit on this counter controls the amount of computing +resource used by a single call to pcre2_match(). The limit can be changed +at run time, as described in the +pcre2api +documentation. The default is 10 million, but this can be changed by adding a +setting such as +

+  --with-match-limit=500000
+
+to the configure command. This setting also applies to the +pcre2_dfa_match() matching function, and to JIT matching (though the +counting is done differently). +

+

+The pcre2_match() function uses heap memory to record backtracking +points. The more nested backtracking points there are (that is, the deeper the +search tree), the more memory is needed. There is an upper limit, specified in +kibibytes (units of 1024 bytes). This limit can be changed at run time, as +described in the +pcre2api +documentation. The default limit (in effect unlimited) is 20 million. You can +change this by a setting such as +

+  --with-heap-limit=500
+
+which limits the amount of heap to 500 KiB. This limit applies only to +interpretive matching in pcre2_match() and pcre2_dfa_match(), which +may also use the heap for internal workspace when processing complicated +patterns. This limit does not apply when JIT (which has its own memory +arrangements) is used. +

+

+You can also explicitly limit the depth of nested backtracking in the +pcre2_match() interpreter. This limit defaults to the value that is set +for --with-match-limit. You can set a lower default limit by adding, for +example, +

+  --with-match-limit-depth=10000
+
+to the configure command. This value can be overridden at run time. This +depth limit indirectly limits the amount of heap memory that is used, but +because the size of each backtracking "frame" depends on the number of +capturing parentheses in a pattern, the amount of heap that is used before the +limit is reached varies from pattern to pattern. This limit was more useful in +versions before 10.30, where function recursion was used for backtracking. +

+

+As well as applying to pcre2_match(), the depth limit also controls +the depth of recursive function calls in pcre2_dfa_match(). These are +used for lookaround assertions, atomic groups, and recursion within patterns. +The limit does not apply to JIT matching. +

+
LIMITING VARIABLE-LENGTH LOOKBEHIND ASSERTIONS
+

+Lookbehind assertions in which one or more branches can match a variable number +of characters are supported only if there is a maximum matching length for each +top-level branch. There is a limit to this maximum that defaults to 255 +characters. You can alter this default by a setting such as +

+  --with-max-varlookbehind=100
+
+The limit can be changed at runtime by calling +pcre2_set_max_varlookbehind(). Lookbehind assertions in which every +branch matches a fixed number of characters (not necessarily all the same) are +not constrained by this limit. +

+
CREATING CHARACTER TABLES AT BUILD TIME
+

+PCRE2 uses fixed tables for processing characters whose code points are less +than 256. By default, PCRE2 is built with a set of tables that are distributed +in the file src/pcre2_chartables.c.dist. These tables are for ASCII codes +only. If you add +

+  --enable-rebuild-chartables
+
+to the configure command, the distributed tables are no longer used. +Instead, a program called pcre2_dftables is compiled and run. This +outputs the source for new set of tables, created in the default locale of your +C run-time system. This method of replacing the tables does not work if you are +cross compiling, because pcre2_dftables needs to be run on the local +host and therefore not compiled with the cross compiler. +

+

+If you need to create alternative tables when cross compiling, you will have to +do so "by hand". There may also be other reasons for creating tables manually. +To cause pcre2_dftables to be built on the local host, run a normal +compiling command, and then run the program with the output file as its +argument, for example: +

+  cc src/pcre2_dftables.c -o pcre2_dftables
+  ./pcre2_dftables src/pcre2_chartables.c
+
+This builds the tables in the default locale of the local host. If you want to +specify a locale, you must use the -L option: +
+  LC_ALL=fr_FR ./pcre2_dftables -L src/pcre2_chartables.c
+
+You can also specify -b (with or without -L). This causes the tables to be +written in binary instead of as source code. A set of binary tables can be +loaded into memory by an application and passed to pcre2_compile() in the +same way as tables created by calling pcre2_maketables(). The tables are +just a string of bytes, independent of hardware characteristics such as +endianness. This means they can be bundled with an application that runs in +different environments, to ensure consistent behaviour. +

+
USING EBCDIC CODE
+

+PCRE2 assumes by default that it will run in an environment where the character +code is ASCII or Unicode, which is a superset of ASCII. This is the case for +most computer operating systems. PCRE2 can, however, be compiled to run in an +8-bit EBCDIC environment by adding +

+  --enable-ebcdic --disable-unicode
+
+to the configure command. This setting implies +--enable-rebuild-chartables. You should only use it if you know that you are in +an EBCDIC environment (for example, an IBM mainframe operating system). +

+

+It is not possible to support both EBCDIC and UTF-8 codes in the same version +of the library. Consequently, --enable-unicode and --enable-ebcdic are mutually +exclusive. +

+

+The EBCDIC character that corresponds to an ASCII LF is assumed to have the +value 0x15 by default. However, in some EBCDIC environments, 0x25 is used. In +such an environment you should use +

+  --enable-ebcdic-nl25
+
+as well as, or instead of, --enable-ebcdic. The EBCDIC character for CR has the +same value as in ASCII, namely, 0x0d. Whichever of 0x15 and 0x25 is not +chosen as LF is made to correspond to the Unicode NEL character (which, in +Unicode, is 0x85). +

+

+The options that select newline behaviour, such as --enable-newline-is-cr, +and equivalent run-time options, refer to these character values in an EBCDIC +environment. +

+
PCRE2GREP SUPPORT FOR EXTERNAL SCRIPTS
+

+By default pcre2grep supports the use of callouts with string arguments +within the patterns it is matching. There are two kinds: one that generates +output using local code, and another that calls an external program or script. +If --disable-pcre2grep-callout-fork is added to the configure command, +only the first kind of callout is supported; if --disable-pcre2grep-callout is +used, all callouts are completely ignored. For more details of pcre2grep +callouts, see the +pcre2grep +documentation. +

+
PCRE2GREP OPTIONS FOR COMPRESSED FILE SUPPORT
+

+By default, pcre2grep reads all files as plain text. You can build it so +that it recognizes files whose names end in .gz or .bz2, and reads +them with libz or libbz2, respectively, by adding one or both of +

+  --enable-pcre2grep-libz
+  --enable-pcre2grep-libbz2
+
+to the configure command. These options naturally require that the +relevant libraries are installed on your system. Configuration will fail if +they are not. +

+
PCRE2GREP BUFFER SIZE
+

+pcre2grep uses an internal buffer to hold a "window" on the file it is +scanning, in order to be able to output "before" and "after" lines when it +finds a match. The default starting size of the buffer is 20KiB. The buffer +itself is three times this size, but because of the way it is used for holding +"before" lines, the longest line that is guaranteed to be processable is the +notional buffer size. If a longer line is encountered, pcre2grep +automatically expands the buffer, up to a specified maximum size, whose default +is 1MiB or the starting size, whichever is the larger. You can change the +default parameter values by adding, for example, +

+  --with-pcre2grep-bufsize=51200
+  --with-pcre2grep-max-bufsize=2097152
+
+to the configure command. The caller of pcre2grep can override +these values by using --buffer-size and --max-buffer-size on the command line. +

+
PCRE2TEST OPTION FOR LIBREADLINE SUPPORT
+

+If you add one of +

+  --enable-pcre2test-libreadline
+  --enable-pcre2test-libedit
+
+to the configure command, pcre2test is linked with the +libreadline orlibedit library, respectively, and when its input is +from a terminal, it reads it using the readline() function. This provides +line-editing and history facilities. Note that libreadline is +GPL-licensed, so if you distribute a binary of pcre2test linked in this +way, there may be licensing issues. These can be avoided by linking instead +with libedit, which has a BSD licence. +

+

+Setting --enable-pcre2test-libreadline causes the -lreadline option to be +added to the pcre2test build. In many operating environments with a +system-installed readline library this is sufficient. However, in some +environments (e.g. if an unmodified distribution version of readline is in +use), some extra configuration may be necessary. The INSTALL file for +libreadline says this: +

+  "Readline uses the termcap functions, but does not link with
+  the termcap or curses library itself, allowing applications
+  which link with readline the to choose an appropriate library."
+
+If your environment has not been set up so that an appropriate library is +automatically included, you may need to add something like +
+  LIBS="-ncurses"
+
+immediately before the configure command. +

+
INCLUDING DEBUGGING CODE
+

+If you add +

+  --enable-debug
+
+to the configure command, additional debugging code is included in the +build. This feature is intended for use by the PCRE2 maintainers. +

+
DEBUGGING WITH VALGRIND SUPPORT
+

+If you add +

+  --enable-valgrind
+
+to the configure command, PCRE2 will use valgrind annotations to mark +certain memory regions as unaddressable. This allows it to detect invalid +memory accesses, and is mostly useful for debugging PCRE2 itself. +

+
CODE COVERAGE REPORTING
+

+If your C compiler is gcc, you can build a version of PCRE2 that can generate a +code coverage report for its test suite. To enable this, you must install +lcov version 1.6 or above. Then specify +

+  --enable-coverage
+
+to the configure command and build PCRE2 in the usual way. +

+

+Note that using ccache (a caching C compiler) is incompatible with code +coverage reporting. If you have configured ccache to run automatically +on your system, you must set the environment variable +

+  CCACHE_DISABLE=1
+
+before running make to build PCRE2, so that ccache is not used. +

+

+When --enable-coverage is used, the following addition targets are added to the +Makefile: +

+  make coverage
+
+This creates a fresh coverage report for the PCRE2 test suite. It is equivalent +to running "make coverage-reset", "make coverage-baseline", "make check", and +then "make coverage-report". +
+  make coverage-reset
+
+This zeroes the coverage counters, but does nothing else. +
+  make coverage-baseline
+
+This captures baseline coverage information. +
+  make coverage-report
+
+This creates the coverage report. +
+  make coverage-clean-report
+
+This removes the generated coverage report without cleaning the coverage data +itself. +
+  make coverage-clean-data
+
+This removes the captured coverage data without removing the coverage files +created at compile time (*.gcno). +
+  make coverage-clean
+
+This cleans all coverage data including the generated coverage report. For more +information about code coverage, see the gcov and lcov +documentation. +

+
DISABLING THE Z AND T FORMATTING MODIFIERS
+

+The C99 standard defines formatting modifiers z and t for size_t and +ptrdiff_t values, respectively. By default, PCRE2 uses these modifiers in +environments other than old versions of Microsoft Visual Studio when +__STDC_VERSION__ is defined and has a value greater than or equal to 199901L +(indicating support for C99). +However, there is at least one environment that claims to be C99 but does not +support these modifiers. If +

+  --disable-percent-zt
+
+is specified, no use is made of the z or t modifiers. Instead of %td or %zu, +a suitable format is used depending in the size of long for the platform. +

+
SUPPORT FOR FUZZERS
+

+There is a special option for use by people who want to run fuzzing tests on +PCRE2: +

+  --enable-fuzz-support
+
+At present this applies only to the 8-bit library. If set, it causes an extra +library called libpcre2-fuzzsupport.a to be built, but not installed. This +contains a single function called LLVMFuzzerTestOneInput() whose arguments are +a pointer to a string and the length of the string. When called, this function +tries to compile the string as a pattern, and if that succeeds, to match it. +This is done both with no options and with some random options bits that are +generated from the string. +

+

+Setting --enable-fuzz-support also causes a binary called pcre2fuzzcheck +to be created. This is normally run under valgrind or used when PCRE2 is +compiled with address sanitizing enabled. It calls the fuzzing function and +outputs information about what it is doing. The input strings are specified by +arguments: if an argument starts with "=" the rest of it is a literal input +string. Otherwise, it is assumed to be a file name, and the contents of the +file are the test string. +

+
OBSOLETE OPTION
+

+In versions of PCRE2 prior to 10.30, there were two ways of handling +backtracking in the pcre2_match() function. The default was to use the +system stack, but if +

+  --disable-stack-for-recursion
+
+was set, memory on the heap was used. From release 10.30 onwards this has +changed (the stack is no longer used) and this option now does nothing except +give a warning. +

+
DESCRIPTION
+

+PCRE2 provides a feature called "callout", which is a means of temporarily +passing control to the caller of PCRE2 in the middle of pattern matching. The +caller of PCRE2 provides an external function by putting its entry point in +a match context (see pcre2_set_callout() in the +pcre2api +documentation). +

+

+When using the pcre2_substitute() function, an additional callout feature +is available. This does a callout after each change to the subject string and +is described in the +pcre2api +documentation; the rest of this document is concerned with callouts during +pattern matching. +

+

+Within a regular expression, (?C<arg>) indicates a point at which the external +function is to be called. Different callout points can be identified by putting +a number less than 256 after the letter C. The default value is zero. +Alternatively, the argument may be a delimited string. The starting delimiter +must be one of ` ' " ^ % # $ { and the ending delimiter is the same as the +start, except for {, where the ending delimiter is }. If the ending delimiter +is needed within the string, it must be doubled. For example, this pattern has +two callout points: +

+  (?C1)abc(?C"some ""arbitrary"" text")def
+
+If the PCRE2_AUTO_CALLOUT option bit is set when a pattern is compiled, PCRE2 +automatically inserts callouts, all with number 255, before each item in the +pattern except for immediately before or after an explicit callout. For +example, if PCRE2_AUTO_CALLOUT is used with the pattern +
+  A(?C3)B
+
+it is processed as if it were +
+  (?C255)A(?C3)B(?C255)
+
+Here is a more complicated example: +
+  A(\d{2}|--)
+
+With PCRE2_AUTO_CALLOUT, this pattern is processed as if it were +
+  (?C255)A(?C255)((?C255)\d{2}(?C255)|(?C255)-(?C255)-(?C255))(?C255)
+
+Notice that there is a callout before and after each parenthesis and +alternation bar. If the pattern contains a conditional group whose condition is +an assertion, an automatic callout is inserted immediately before the +condition. Such a callout may also be inserted explicitly, for example: +
+  (?(?C9)(?=a)ab|de)  (?(?C%text%)(?!=d)ab|de)
+
+This applies only to assertion conditions (because they are themselves +independent groups). +

+

+Callouts can be useful for tracking the progress of pattern matching. The +pcre2test +program has a pattern qualifier (/auto_callout) that sets automatic callouts. +When any callouts are present, the output from pcre2test indicates how +the pattern is being matched. This is useful information when you are trying to +optimize the performance of a particular pattern. +

+
MISSING CALLOUTS
+

+You should be aware that, because of optimizations in the way PCRE2 compiles +and matches patterns, callouts sometimes do not happen exactly as you might +expect. +

+
+Auto-possessification +
+

+At compile time, PCRE2 "auto-possessifies" repeated items when it knows that +what follows cannot be part of the repeat. For example, a+[bc] is compiled as +if it were a++[bc]. The pcre2test output when this pattern is compiled +with PCRE2_ANCHORED and PCRE2_AUTO_CALLOUT and then applied to the string +"aaaa" is: +

+  --->aaaa
+   +0 ^        a+
+   +2 ^   ^    [bc]
+  No match
+
+This indicates that when matching [bc] fails, there is no backtracking into a+ +(because it is being treated as a++) and therefore the callouts that would be +taken for the backtracks do not occur. You can disable the auto-possessify +feature by passing PCRE2_NO_AUTO_POSSESS to pcre2_compile(), or starting +the pattern with (*NO_AUTO_POSSESS). In this case, the output changes to this: +
+  --->aaaa
+   +0 ^        a+
+   +2 ^   ^    [bc]
+   +2 ^  ^     [bc]
+   +2 ^ ^      [bc]
+   +2 ^^       [bc]
+  No match
+
+This time, when matching [bc] fails, the matcher backtracks into a+ and tries +again, repeatedly, until a+ itself fails. +

+
+Automatic .* anchoring +
+

+By default, an optimization is applied when .* is the first significant item in +a pattern. If PCRE2_DOTALL is set, so that the dot can match any character, the +pattern is automatically anchored. If PCRE2_DOTALL is not set, a match can +start only after an internal newline or at the beginning of the subject, and +pcre2_compile() remembers this. If a pattern has more than one top-level +branch, automatic anchoring occurs if all branches are anchorable. +

+

+This optimization is disabled, however, if .* is in an atomic group or if there +is a backreference to the capture group in which it appears. It is also +disabled if the pattern contains (*PRUNE) or (*SKIP). However, the presence of +callouts does not affect it. +

+

+For example, if the pattern .*\d is compiled with PCRE2_AUTO_CALLOUT and +applied to the string "aa", the pcre2test output is: +

+  --->aa
+   +0 ^      .*
+   +2 ^ ^    \d
+   +2 ^^     \d
+   +2 ^      \d
+  No match
+
+This shows that all match attempts start at the beginning of the subject. In +other words, the pattern is anchored. You can disable this optimization by +passing PCRE2_NO_DOTSTAR_ANCHOR to pcre2_compile(), or starting the +pattern with (*NO_DOTSTAR_ANCHOR). In this case, the output changes to: +
+  --->aa
+   +0 ^      .*
+   +2 ^ ^    \d
+   +2 ^^     \d
+   +2 ^      \d
+   +0  ^     .*
+   +2  ^^    \d
+   +2  ^     \d
+  No match
+
+This shows more match attempts, starting at the second subject character. +Another optimization, described in the next section, means that there is no +subsequent attempt to match with an empty subject. +

+
+Other optimizations +
+

+Other optimizations that provide fast "no match" results also affect callouts. +For example, if the pattern is +

+  ab(?C4)cd
+
+PCRE2 knows that any matching string must contain the letter "d". If the +subject string is "abyz", the lack of "d" means that matching doesn't ever +start, and the callout is never reached. However, with "abyd", though the +result is still no match, the callout is obeyed. +

+

+For most patterns PCRE2 also knows the minimum length of a matching string, and +will immediately give a "no match" return without actually running a match if +the subject is not long enough, or, for unanchored patterns, if it has been +scanned far enough. +

+

+You can disable these optimizations by passing the PCRE2_NO_START_OPTIMIZE +option to pcre2_compile(), or by starting the pattern with +(*NO_START_OPT). This slows down the matching process, but does ensure that +callouts such as the example above are obeyed. +

+
THE CALLOUT INTERFACE
+

+During matching, when PCRE2 reaches a callout point, if an external function is +provided in the match context, it is called. This applies to both normal, +DFA, and JIT matching. The first argument to the callout function is a pointer +to a pcre2_callout block. The second argument is the void * callout data +that was supplied when the callout was set up by calling +pcre2_set_callout() (see the +pcre2api +documentation). The callout block structure contains the following fields, not +necessarily in this order: +

+  uint32_t      version;
+  uint32_t      callout_number;
+  uint32_t      capture_top;
+  uint32_t      capture_last;
+  uint32_t      callout_flags;
+  PCRE2_SIZE   *offset_vector;
+  PCRE2_SPTR    mark;
+  PCRE2_SPTR    subject;
+  PCRE2_SIZE    subject_length;
+  PCRE2_SIZE    start_match;
+  PCRE2_SIZE    current_position;
+  PCRE2_SIZE    pattern_position;
+  PCRE2_SIZE    next_item_length;
+  PCRE2_SIZE    callout_string_offset;
+  PCRE2_SIZE    callout_string_length;
+  PCRE2_SPTR    callout_string;
+
+The version field contains the version number of the block format. The +current version is 2; the three callout string fields were added for version 1, +and the callout_flags field for version 2. If you are writing an +application that might use an earlier release of PCRE2, you should check the +version number before accessing any of these fields. The version number will +increase in future if more fields are added, but the intention is never to +remove any of the existing fields. +

+
+Fields for numerical callouts +
+

+For a numerical callout, callout_string is NULL, and callout_number +contains the number of the callout, in the range 0-255. This is the number +that follows (?C for callouts that part of the pattern; it is 255 for +automatically generated callouts. +

+
+Fields for string callouts +
+

+For callouts with string arguments, callout_number is always zero, and +callout_string points to the string that is contained within the compiled +pattern. Its length is given by callout_string_length. Duplicated ending +delimiters that were present in the original pattern string have been turned +into single characters, but there is no other processing of the callout string +argument. An additional code unit containing binary zero is present after the +string, but is not included in the length. The delimiter that was used to start +the string is also stored within the pattern, immediately before the string +itself. You can access this delimiter as callout_string[-1] if you need +it. +

+

+The callout_string_offset field is the code unit offset to the start of +the callout argument string within the original pattern string. This is +provided for the benefit of applications such as script languages that might +need to report errors in the callout string within the pattern. +

+
+Fields for all callouts +
+

+The remaining fields in the callout block are the same for both kinds of +callout. +

+

+The offset_vector field is a pointer to a vector of capturing offsets +(the "ovector"). You may read the elements in this vector, but you must not +change any of them. +

+

+For calls to pcre2_match(), the offset_vector field is not (since +release 10.30) a pointer to the actual ovector that was passed to the matching +function in the match data block. Instead it points to an internal ovector of a +size large enough to hold all possible captured substrings in the pattern. Note +that whenever a recursion or subroutine call within a pattern completes, the +capturing state is reset to what it was before. +

+

+The capture_last field contains the number of the most recently captured +substring, and the capture_top field contains one more than the number of +the highest numbered captured substring so far. If no substrings have yet been +captured, the value of capture_last is 0 and the value of +capture_top is 1. The values of these fields do not always differ by one; +for example, when the callout in the pattern ((a)(b))(?C2) is taken, +capture_last is 1 but capture_top is 4. +

+

+The contents of ovector[2] to ovector[<capture_top>*2-1] can be inspected in +order to extract substrings that have been matched so far, in the same way as +extracting substrings after a match has completed. The values in ovector[0] and +ovector[1] are always PCRE2_UNSET because the match is by definition not +complete. Substrings that have not been captured but whose numbers are less +than capture_top also have both of their ovector slots set to +PCRE2_UNSET. +

+

+For DFA matching, the offset_vector field points to the ovector that was +passed to the matching function in the match data block for callouts at the top +level, but to an internal ovector during the processing of pattern recursions, +lookarounds, and atomic groups. However, these ovectors hold no useful +information because pcre2_dfa_match() does not support substring +capturing. The value of capture_top is always 1 and the value of +capture_last is always 0 for DFA matching. +

+

+The subject and subject_length fields contain copies of the values +that were passed to the matching function. +

+

+The start_match field normally contains the offset within the subject at +which the current match attempt started. However, if the escape sequence \K +has been encountered, this value is changed to reflect the modified starting +point. If the pattern is not anchored, the callout function may be called +several times from the same point in the pattern for different starting points +in the subject. +

+

+The current_position field contains the offset within the subject of the +current match pointer. +

+

+The pattern_position field contains the offset in the pattern string to +the next item to be matched. +

+

+The next_item_length field contains the length of the next item to be +processed in the pattern string. When the callout is at the end of the pattern, +the length is zero. When the callout precedes an opening parenthesis, the +length includes meta characters that follow the parenthesis. For example, in a +callout before an assertion such as (?=ab) the length is 3. For an alternation +bar or a closing parenthesis, the length is one, unless a closing parenthesis +is followed by a quantifier, in which case its length is included. (This +changed in release 10.23. In earlier releases, before an opening parenthesis +the length was that of the entire group, and before an alternation bar or a +closing parenthesis the length was zero.) +

+

+The pattern_position and next_item_length fields are intended to +help in distinguishing between different automatic callouts, which all have the +same callout number. However, they are set for all callouts, and are used by +pcre2test to show the next item to be matched when displaying callout +information. +

+

+In callouts from pcre2_match() the mark field contains a pointer to +the zero-terminated name of the most recently passed (*MARK), (*PRUNE), or +(*THEN) item in the match, or NULL if no such items have been passed. Instances +of (*PRUNE) or (*THEN) without a name do not obliterate a previous (*MARK). In +callouts from the DFA matching function this field always contains NULL. +

+

+The callout_flags field is always zero in callouts from +pcre2_dfa_match() or when JIT is being used. When pcre2_match() +without JIT is used, the following bits may be set: +

+  PCRE2_CALLOUT_STARTMATCH
+
+This is set for the first callout after the start of matching for each new +starting position in the subject. +
+  PCRE2_CALLOUT_BACKTRACK
+
+This is set if there has been a matching backtrack since the previous callout, +or since the start of matching if this is the first callout from a +pcre2_match() run. +

+

+Both bits are set when a backtrack has caused a "bumpalong" to a new starting +position in the subject. Output from pcre2test does not indicate the +presence of these bits unless the callout_extra modifier is set. +

+

+The information in the callout_flags field is provided so that +applications can track and tell their users how matching with backtracking is +done. This can be useful when trying to optimize patterns, or just to +understand how PCRE2 works. There is no support in pcre2_dfa_match() +because there is no backtracking in DFA matching, and there is no support in +JIT because JIT is all about maximimizing matching performance. In both these +cases the callout_flags field is always zero. +

+
RETURN VALUES FROM CALLOUTS
+

+The external callout function returns an integer to PCRE2. If the value is +zero, matching proceeds as normal. If the value is greater than zero, matching +fails at the current point, but the testing of other matching possibilities +goes ahead, just as if a lookahead assertion had failed. If the value is less +than zero, the match is abandoned, and the matching function returns the +negative value. +

+

+Negative values should normally be chosen from the set of PCRE2_ERROR_xxx +values. In particular, PCRE2_ERROR_NOMATCH forces a standard "no match" +failure. The error number PCRE2_ERROR_CALLOUT is reserved for use by callout +functions; it will never be used by PCRE2 itself. +

+
CALLOUT ENUMERATION
+

+int pcre2_callout_enumerate(const pcre2_code *code, + int (*callback)(pcre2_callout_enumerate_block *, void *), + void *user_data); +
+
+A script language that supports the use of string arguments in callouts might +like to scan all the callouts in a pattern before running the match. This can +be done by calling pcre2_callout_enumerate(). The first argument is a +pointer to a compiled pattern, the second points to a callback function, and +the third is arbitrary user data. The callback function is called for every +callout in the pattern in the order in which they appear. Its first argument is +a pointer to a callout enumeration block, and its second argument is the +user_data value that was passed to pcre2_callout_enumerate(). The +data block contains the following fields: +

+  version                Block version number
+  pattern_position       Offset to next item in pattern
+  next_item_length       Length of next item in pattern
+  callout_number         Number for numbered callouts
+  callout_string_offset  Offset to string within pattern
+  callout_string_length  Length of callout string
+  callout_string         Points to callout string or is NULL
+
+The version number is currently 0. It will increase if new fields are ever +added to the block. The remaining fields are the same as their namesakes in the +pcre2_callout block that is used for callouts during matching, as +described +above. +

+

+Note that the value of pattern_position is unique for each callout. +However, if a callout occurs inside a group that is quantified with a non-zero +minimum or a fixed maximum, the group is replicated inside the compiled +pattern. For example, a pattern such as /(a){2}/ is compiled as if it were +/(a)(a)/. This means that the callout will be enumerated more than once, but +with the same value for pattern_position in each case. +

+

+The callback function should normally return zero. If it returns a non-zero +value, scanning the pattern stops, and that value is returned from +pcre2_callout_enumerate(). +

+
+DIFFERENCES BETWEEN PCRE2 AND PERL +
+

+This document describes some of the known differences in the ways that PCRE2 +and Perl handle regular expressions. The differences described here are with +respect to Perl version 5.38.0, but as both Perl and PCRE2 are continually +changing, the information may at times be out of date. +

+

+1. When PCRE2_DOTALL (equivalent to Perl's /s qualifier) is not set, the +behaviour of the '.' metacharacter differs from Perl. In PCRE2, '.' matches the +next character unless it is the start of a newline sequence. This means that, +if the newline setting is CR, CRLF, or NUL, '.' will match the code point LF +(0x0A) in ASCII/Unicode environments, and NL (either 0x15 or 0x25) when using +EBCDIC. In Perl, '.' appears never to match LF, even when 0x0A is not a newline +indicator. +

+

+2. PCRE2 has only a subset of Perl's Unicode support. Details of what it does +have are given in the +pcre2unicode +page. +

+

+3. Like Perl, PCRE2 allows repeat quantifiers on parenthesized assertions, but +they do not mean what you might think. For example, (?!a){3} does not assert +that the next three characters are not "a". It just asserts that the next +character is not "a" three times (in principle; PCRE2 optimizes this to run the +assertion just once). Perl allows some repeat quantifiers on other assertions, +for example, \b* , but these do not seem to have any use. PCRE2 does not allow +any kind of quantifier on non-lookaround assertions. +

+

+4. If a braced quantifier such as {1,2} appears where there is nothing to +repeat (for example, at the start of a branch), PCRE2 raises an error whereas +Perl treats the quantifier characters as literal. +

+

+5. Capture groups that occur inside negative lookaround assertions are counted, +but their entries in the offsets vector are set only when a negative assertion +is a condition that has a matching branch (that is, the condition is false). +Perl may set such capture groups in other circumstances. +

+

+6. The following Perl escape sequences are not supported: \F, \l, \L, \u, +\U, and \N when followed by a character name. \N on its own, matching a +non-newline character, and \N{U+dd..}, matching a Unicode code point, are +supported. The escapes that modify the case of following letters are +implemented by Perl's general string-handling and are not part of its pattern +matching engine. If any of these are encountered by PCRE2, an error is +generated by default. However, if either of the PCRE2_ALT_BSUX or +PCRE2_EXTRA_ALT_BSUX options is set, \U and \u are interpreted as ECMAScript +interprets them. +

+

+7. The Perl escape sequences \p, \P, and \X are supported only if PCRE2 is +built with Unicode support (the default). The properties that can be tested +with \p and \P are limited to the general category properties such as Lu and +Nd, the derived properties Any and LC (synonym L&), script names such as Greek +or Han, Bidi_Class, Bidi_Control, and a few binary properties. Both PCRE2 and +Perl support the Cs (surrogate) property, but in PCRE2 its use is limited. See +the +pcre2pattern +documentation for details. The long synonyms for property names that Perl +supports (such as \p{Letter}) are not supported by PCRE2, nor is it permitted +to prefix any of these properties with "Is". +

+

+8. PCRE2 supports the \Q...\E escape for quoting substrings. Characters +in between are treated as literals. However, this is slightly different from +Perl in that $ and @ are also handled as literals inside the quotes. In Perl, +they cause variable interpolation (PCRE2 does not have variables). Also, Perl +does "double-quotish backslash interpolation" on any backslashes between \Q +and \E which, its documentation says, "may lead to confusing results". PCRE2 +treats a backslash between \Q and \E just like any other character. Note the +following examples: +

+    Pattern            PCRE2 matches     Perl matches
+
+    \Qabc$xyz\E        abc$xyz           abc followed by the contents of $xyz
+    \Qabc\$xyz\E       abc\$xyz          abc\$xyz
+    \Qabc\E\$\Qxyz\E   abc$xyz           abc$xyz
+    \QA\B\E            A\B               A\B
+    \Q\\E              \                 \\E
+
+The \Q...\E sequence is recognized both inside and outside character classes +by both PCRE2 and Perl. +

+

+9. Fairly obviously, PCRE2 does not support the (?{code}) and (??{code}) +constructions. However, PCRE2 does have a "callout" feature, which allows an +external function to be called during pattern matching. See the +pcre2callout +documentation for details. +

+

+10. Subroutine calls (whether recursive or not) were treated as atomic groups +up to PCRE2 release 10.23, but from release 10.30 this changed, and +backtracking into subroutine calls is now supported, as in Perl. +

+

+11. In PCRE2, if any of the backtracking control verbs are used in a group that +is called as a subroutine (whether or not recursively), their effect is +confined to that group; it does not extend to the surrounding pattern. This is +not always the case in Perl. In particular, if (*THEN) is present in a group +that is called as a subroutine, its action is limited to that group, even if +the group does not contain any | characters. Note that such groups are +processed as anchored at the point where they are tested. +

+

+12. If a pattern contains more than one backtracking control verb, the first +one that is backtracked onto acts. For example, in the pattern +A(*COMMIT)B(*PRUNE)C a failure in B triggers (*COMMIT), but a failure in C +triggers (*PRUNE). Perl's behaviour is more complex; in many cases it is the +same as PCRE2, but there are cases where it differs. +

+

+13. There are some differences that are concerned with the settings of captured +strings when part of a pattern is repeated. For example, matching "aba" against +the pattern /^(a(b)?)+$/ in Perl leaves $2 unset, but in PCRE2 it is set to +"b". +

+

+14. PCRE2's handling of duplicate capture group numbers and names is not as +general as Perl's. This is a consequence of the fact the PCRE2 works internally +just with numbers, using an external table to translate between numbers and +names. In particular, a pattern such as (?|(?<a>A)|(?<b>B)), where the two +capture groups have the same number but different names, is not supported, and +causes an error at compile time. If it were allowed, it would not be possible +to distinguish which group matched, because both names map to capture group +number 1. To avoid this confusing situation, an error is given at compile time. +

+

+15. Perl used to recognize comments in some places that PCRE2 does not, for +example, between the ( and ? at the start of a group. If the /x modifier is +set, Perl allowed white space between ( and ? though the latest Perls give an +error (for a while it was just deprecated). There may still be some cases where +Perl behaves differently. +

+

+16. Perl, when in warning mode, gives warnings for character classes such as +[A-\d] or [a-[:digit:]]. It then treats the hyphens as literals. PCRE2 has no +warning features, so it gives an error in these cases because they are almost +certainly user mistakes. +

+

+17. In PCRE2, the upper/lower case character properties Lu and Ll are not +affected when case-independent matching is specified. For example, \p{Lu} +always matches an upper case letter. I think Perl has changed in this respect; +in the release at the time of writing (5.38), \p{Lu} and \p{Ll} match all +letters, regardless of case, when case independence is specified. +

+

+18. From release 5.32.0, Perl locks out the use of \K in lookaround +assertions. From release 10.38 PCRE2 does the same by default. However, there +is an option for re-enabling the previous behaviour. When this option is set, +\K is acted on when it occurs in positive assertions, but is ignored in +negative assertions. +

+

+19. PCRE2 provides some extensions to the Perl regular expression facilities. +Perl 5.10 included new features that were not in earlier versions of Perl, some +of which (such as named parentheses) were in PCRE2 for some time before. This +list is with respect to Perl 5.38: +
+
+(a) If PCRE2_DOLLAR_ENDONLY is set and PCRE2_MULTILINE is not set, the $ +meta-character matches only at the very end of the string. +
+
+(b) A backslash followed by a letter with no special meaning is faulted. (Perl +can be made to issue a warning.) +
+
+(c) If PCRE2_UNGREEDY is set, the greediness of the repetition quantifiers is +inverted, that is, by default they are not greedy, but if followed by a +question mark they are. +
+
+(d) PCRE2_ANCHORED can be used at matching time to force a pattern to be tried +only at the first matching position in the subject string. +
+
+(e) The PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY and PCRE2_NOTEMPTY_ATSTART +options have no Perl equivalents. +
+
+(f) The \R escape sequence can be restricted to match only CR, LF, or CRLF +by the PCRE2_BSR_ANYCRLF option. +
+
+(g) The callout facility is PCRE2-specific. Perl supports codeblocks and +variable interpolation, but not general hooks on every match. +
+
+(h) The partial matching facility is PCRE2-specific. +
+
+(i) The alternative matching function (pcre2_dfa_match() matches in a +different way and is not Perl-compatible. +
+
+(j) PCRE2 recognizes some special sequences such as (*CR) or (*NO_JIT) at +the start of a pattern. These set overall options that cannot be changed within +the pattern. +
+
+(k) PCRE2 supports non-atomic positive lookaround assertions. This is an +extension to the lookaround facilities. The default, Perl-compatible +lookarounds are atomic. +
+
+(l) There are three syntactical items in patterns that can refer to a capturing +group by number: back references such as \g{2}, subroutine calls such as (?3), +and condition references such as (?(4)...). PCRE2 supports relative group +numbers such as +2 and -4 in all three cases. Perl supports both plus and minus +for subroutine calls, but only minus for back references, and no relative +numbering at all for conditions. +

+

+20. Perl has different limits than PCRE2. See the +pcre2limit +documentation for details. Perl went with 5.10 from recursion to iteration +keeping the intermediate matches on the heap, which is ~10% slower but does not +fall into any stack-overflow limit. PCRE2 made a similar change at release +10.30, and also has many build-time and run-time customizable limits. +

+

+21. Unlike Perl, PCRE2 doesn't have character set modifiers and specially no way +to set characters by context just like Perl's "/d". A regular expression using +PCRE2_UTF and PCRE2_UCP will use similar rules to Perl's "/u"; something closer +to "/a" could be selected by adding other PCRE2_EXTRA_ASCII* options on top. +

+

+22. Some recursive patterns that Perl diagnoses as infinite recursions can be +handled by PCRE2, either by the interpreter or the JIT. An example is +/(?:|(?0)abcd)(?(R)|\z)/, which matches a sequence of any number of repeated +"abcd" substrings at the end of the subject. +

EXPERIMENTAL PATTERN CONVERSION FUNCTIONS
+

+This document describes a set of functions that can be used to convert +"foreign" patterns into PCRE2 regular expressions. This facility is currently +experimental, and may be changed in future releases. Two kinds of pattern, +globs and POSIX patterns, are supported. +

+
THE CONVERT CONTEXT
+

+pcre2_convert_context *pcre2_convert_context_create( + pcre2_general_context *gcontext); +
+
+pcre2_convert_context *pcre2_convert_context_copy( + pcre2_convert_context *cvcontext); +
+
+void pcre2_convert_context_free(pcre2_convert_context *cvcontext); +
+
+int pcre2_set_glob_escape(pcre2_convert_context *cvcontext, + uint32_t escape_char); +
+
+int pcre2_set_glob_separator(pcre2_convert_context *cvcontext, + uint32_t separator_char); +
+
+A convert context is used to hold parameters that affect the way that pattern +conversion works. Like all PCRE2 contexts, you need to use a context only if +you want to override the defaults. There are the usual create, copy, and free +functions. If custom memory management functions are set in a general context +that is passed to pcre2_convert_context_create(), they are used for all +memory management within the conversion functions. +

+

+There are only two parameters in the convert context at present. Both apply +only to glob conversions. The escape character defaults to grave accent under +Windows, otherwise backslash. It can be set to zero, meaning no escape +character, or to any punctuation character with a code point less than 256. +The separator character defaults to backslash under Windows, otherwise forward +slash. It can be set to forward slash, backslash, or dot. +

+

+The two setting functions return zero on success, or PCRE2_ERROR_BADDATA if +their second argument is invalid. +

+
THE CONVERSION FUNCTION
+

+int pcre2_pattern_convert(PCRE2_SPTR pattern, PCRE2_SIZE length, + uint32_t options, PCRE2_UCHAR **buffer, + PCRE2_SIZE *blength, pcre2_convert_context *cvcontext); +
+
+void pcre2_converted_pattern_free(PCRE2_UCHAR *converted_pattern); +
+
+The first two arguments of pcre2_pattern_convert() define the foreign +pattern that is to be converted. The length may be given as +PCRE2_ZERO_TERMINATED. The options argument defines how the pattern is to +be processed. If the input is UTF, the PCRE2_CONVERT_UTF option should be set. +PCRE2_CONVERT_NO_UTF_CHECK may also be set if you are sure the input is valid. +One or more of the glob options, or one of the following POSIX options must be +set to define the type of conversion that is required: +

+  PCRE2_CONVERT_GLOB
+  PCRE2_CONVERT_GLOB_NO_WILD_SEPARATOR
+  PCRE2_CONVERT_GLOB_NO_STARSTAR
+  PCRE2_CONVERT_POSIX_BASIC
+  PCRE2_CONVERT_POSIX_EXTENDED
+
+Details of the conversions are given below. The buffer and blength +arguments define how the output is handled: +

+

+If buffer is NULL, the function just returns the length of the converted +pattern via blength. This is one less than the length of buffer needed, +because a terminating zero is always added to the output. +

+

+If buffer points to a NULL pointer, an output buffer is obtained using +the allocator in the context or malloc() if no context is supplied. A +pointer to this buffer is placed in the variable to which buffer points. +When no longer needed the output buffer must be freed by calling +pcre2_converted_pattern_free(). If this function is called with a NULL +argument, it returns immediately without doing anything. +

+

+If buffer points to a non-NULL pointer, blength must be set to the +actual length of the buffer provided (in code units). +

+

+In all cases, after successful conversion, the variable pointed to by +blength is updated to the length actually used (in code units), excluding +the terminating zero that is always added. +

+

+If an error occurs, the length (via blength) is set to the offset +within the input pattern where the error was detected. Only gross syntax errors +are caught; there are plenty of errors that will get passed on for +pcre2_compile() to discover. +

+

+The return from pcre2_pattern_convert() is zero on success or a non-zero +PCRE2 error code. Note that PCRE2 error codes may be positive or negative: +pcre2_compile() uses mostly positive codes and pcre2_match() +negative ones; pcre2_convert() uses existing codes of both kinds. A +textual error message can be obtained by calling +pcre2_get_error_message(). +

+
CONVERTING GLOBS
+

+Globs are used to match file names, and consequently have the concept of a +"path separator", which defaults to backslash under Windows and forward slash +otherwise. If PCRE2_CONVERT_GLOB is set, the wildcards * and ? are not +permitted to match separator characters, but the double-star (**) feature +(which does match separators) is supported. +

+

+PCRE2_CONVERT_GLOB_NO_WILD_SEPARATOR matches globs with wildcards allowed to +match separator characters. PCRE2_CONVERT_GLOB_NO_STARSTAR matches globs with +the double-star feature disabled. These options may be given together. +

+
CONVERTING POSIX PATTERNS
+

+POSIX defines two kinds of regular expression pattern: basic and extended. +These can be processed by setting PCRE2_CONVERT_POSIX_BASIC or +PCRE2_CONVERT_POSIX_EXTENDED, respectively. +

+

+In POSIX patterns, backslash is not special in a character class. Unmatched +closing parentheses are treated as literals. +

+

+In basic patterns, ? + | {} and () must be escaped to be recognized +as metacharacters outside a character class. If the first character in the +pattern is * it is treated as a literal. ^ is a metacharacter only at the start +of a branch. +

+

+In extended patterns, a backslash not in a character class always +makes the next character literal, whatever it is. There are no backreferences. +

+

+Note: POSIX mandates that the longest possible match at the first matching +position must be found. This is not what pcre2_match() does; it yields +the first match that is found. An application can use pcre2_dfa_match() +to find the longest match, but that does not support backreferences (but then +neither do POSIX extended patterns). +

+/*************************************************
+*           PCRE2 DEMONSTRATION PROGRAM          *
+*************************************************/
+
+/* This is a demonstration program to illustrate a straightforward way of
+using the PCRE2 regular expression library from a C program. See the
+pcre2sample documentation for a short discussion ("man pcre2sample" if you have
+the PCRE2 man pages installed). PCRE2 is a revised API for the library, and is
+incompatible with the original PCRE API.
+
+There are actually three libraries, each supporting a different code unit
+width. This demonstration program uses the 8-bit library. The default is to
+process each code unit as a separate character, but if the pattern begins with
+"(*UTF)", both it and the subject are treated as UTF-8 strings, where
+characters may occupy multiple code units.
+
+In Unix-like environments, if PCRE2 is installed in your standard system
+libraries, you should be able to compile this program using this command:
+
+cc -Wall pcre2demo.c -lpcre2-8 -o pcre2demo
+
+If PCRE2 is not installed in a standard place, it is likely to be installed
+with support for the pkg-config mechanism. If you have pkg-config, you can
+compile this program using this command:
+
+cc -Wall pcre2demo.c `pkg-config --cflags --libs libpcre2-8` -o pcre2demo
+
+If you do not have pkg-config, you may have to use something like this:
+
+cc -Wall pcre2demo.c -I/usr/local/include -L/usr/local/lib \
+  -R/usr/local/lib -lpcre2-8 -o pcre2demo
+
+Replace "/usr/local/include" and "/usr/local/lib" with wherever the include and
+library files for PCRE2 are installed on your system. Only some operating
+systems (Solaris is one) use the -R option.
+
+Building under Windows:
+
+If you want to statically link this program against a non-dll .a file, you must
+define PCRE2_STATIC before including pcre2.h, so in this environment, uncomment
+the following line. */
+
+/* #define PCRE2_STATIC */
+
+/* The PCRE2_CODE_UNIT_WIDTH macro must be defined before including pcre2.h.
+For a program that uses only one code unit width, setting it to 8, 16, or 32
+makes it possible to use generic function names such as pcre2_compile(). Note
+that just changing 8 to 16 (for example) is not sufficient to convert this
+program to process 16-bit characters. Even in a fully 16-bit environment, where
+string-handling functions such as strcmp() and printf() work with 16-bit
+characters, the code for handling the table of named substrings will still need
+to be modified. */

+* would lead to an infinite loop. Instead, a call of pcre2_match() is    *
+* made with the PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set. The *
+* first of these tells PCRE2 that an empty string at the start of the    *
+* subject is not a valid match; other possibilities must be tried. The   *
+* second flag restricts PCRE2 to one match attempt at the initial string *
+* position. If this match succeeds, an alternative to the empty string   *
+* match has been found, and we can print it and proceed round the loop,  *
+* advancing by the length of whatever was found. If this match does not  *
+* succeed, we still stay in the loop, advancing by just one character.   *

SYNOPSIS

+

+pcre2grep [options] [long options] [pattern] [path1 path2 ...]
+

+
DESCRIPTION

+

+pcre2grep searches files for character patterns, in the same way as other
+grep commands do, but it uses the PCRE2 regular expression library to support
+patterns that are compatible with the regular expressions of Perl 5. See
+pcre2syntax(3)
+for a quick-reference summary of pattern syntax, or
+pcre2pattern(3)
+for a full description of the syntax and semantics of the regular expressions
+that PCRE2 supports.
+

+

+Patterns, whether supplied on the command line or in a separate file, are given
+without delimiters. For example:
+
+  pcre2grep Thursday /etc/motd
+

+If you attempt to use delimiters (for example, by surrounding a pattern with
+slashes, as is common in Perl scripts), they are interpreted as part of the
+pattern. Quotes can of course be used to delimit patterns on the command line
+because they are interpreted by the shell, and indeed quotes are required if a
+pattern contains white space or shell metacharacters.
+

+

+The first argument that follows any option settings is treated as the single
+pattern to be matched when neither -e nor -f is present.
+Conversely, when one or both of these options are used to specify patterns, all
+arguments are treated as path names. At least one of -e, -f, or an
+argument pattern must be provided.
+

+

+If no files are specified, pcre2grep reads the standard input. The
+standard input can also be referenced by a name consisting of a single hyphen.
+For example:
+
+  pcre2grep some-pattern file1 - file3
+

+By default, input files are searched line by line, so pattern assertions about
+the beginning and end of a subject string (^, $, \A, \Z, and \z) match at
+the beginning and end of each line. When a line matches a pattern, it is copied
+to the standard output, and if there is more than one file, the file name is
+output at the start of each line, followed by a colon. However, there are
+options that can change how pcre2grep behaves. For example, the -M
+option makes it possible to search for strings that span line boundaries. What
+defines a line boundary is controlled by the -N (--newline) option.
+The -h and -H options control whether or not file names are shown,
+and the -Z option changes the file name terminator to a zero byte.
+

+

+The amount of memory used for buffering files that are being scanned is
+controlled by parameters that can be set by the --buffer-size and
+--max-buffer-size options. The first of these sets the size of buffer
+that is obtained at the start of processing. If an input file contains very
+long lines, a larger buffer may be needed; this is handled by automatically
+extending the buffer, up to the limit specified by --max-buffer-size. The
+default values for these parameters can be set when pcre2grep is
+built; if nothing is specified, the defaults are set to 20KiB and 1MiB
+respectively. An error occurs if a line is too long and the buffer can no
+longer be expanded.
+

+

+The block of memory that is actually used is three times the "buffer size", to
+allow for buffering "before" and "after" lines. If the buffer size is too
+small, fewer than requested "before" and "after" lines may be output.
+

+

+When matching with a multiline pattern, the size of the buffer must be at least
+half of the maximum match expected or the pattern might fail to match.
+

+

+Patterns can be no longer than 8KiB or BUFSIZ bytes, whichever is the greater.
+BUFSIZ is defined in <stdio.h>. When there is more than one pattern
+(specified by the use of -e and/or -f), each pattern is applied to
+each line in the order in which they are defined, except that all the -e
+patterns are tried before the -f patterns.
+

+

+By default, as soon as one pattern matches a line, no further patterns are
+considered. However, if --colour (or --color) is used to colour the
+matching substrings, or if --only-matching, --file-offsets,
+--line-offsets, or --output is used to output only the part of the
+line that matched (either shown literally, or as an offset), the behaviour is
+different. In this situation, all the patterns are applied to the line. If
+there is more than one match, the one that begins nearest to the start of the
+subject is processed; if there is more than one match at that position, the one
+with the longest matching substring is processed; if the matching substrings
+are equal, the first match found is processed.
+

+

+Scanning with all the patterns resumes immediately following the match, so that
+later matches on the same line can be found. Note, however, that an overlapping
+match that starts in the middle of another match will not be processed.
+

+

+The above behaviour was changed at release 10.41 to be more compatible with GNU
+grep. In earlier releases, pcre2grep did not recognize matches from
+later patterns that were earlier in the subject.
+

+

+Patterns that can match an empty string are accepted, but empty string
+matches are never recognized. An example is the pattern "(super)?(man)?", in
+which all components are optional. This pattern finds all occurrences of both
+"super" and "man"; the output differs from matching with "super|man" when only
+the matching substrings are being shown.
+

+

+If the LC_ALL or LC_CTYPE environment variable is set,
+pcre2grep uses the value to set a locale when calling the PCRE2 library.
+The --locale option can be used to override this.
+

+
SUPPORT FOR COMPRESSED FILES

+

+Compile-time options for pcre2grep can set it up to use libz or
+libbz2 for reading compressed files whose names end in .gz or
+.bz2, respectively. You can find out whether your pcre2grep binary
+has support for one or both of these file types by running it with the
+--help option. If the appropriate support is not present, all files are
+treated as plain text. The standard input is always so treated. If a file with
+a .gz or .bz2 extension is not in fact compressed, it is read as a
+plain text file. When input is from a compressed .gz or .bz2 file, the
+--line-buffered option is ignored.
+

+
BINARY FILES

+

+By default, a file that contains a binary zero byte within the first 1024 bytes
+is identified as a binary file, and is processed specially. However, if the
+newline type is specified as NUL, that is, the line terminator is a binary
+zero, the test for a binary file is not applied. See the --binary-files
+option for a means of changing the way binary files are handled.
+

+
BINARY ZEROS IN PATTERNS

+

+Patterns passed from the command line are strings that are terminated by a
+binary zero, so cannot contain internal zeros. However, patterns that are read
+from a file via the -f option may contain binary zeros.
+

+
OPTIONS

+

+The order in which some of the options appear can affect the output. For
+example, both the -H and -l options affect the printing of file
+names. Whichever comes later in the command line will be the one that takes
+effect. Similarly, except where noted below, if an option is given twice, the
+later setting is used. Numerical values for options may be followed by K or M,
+to signify multiplication by 1024 or 1024*1024 respectively.
+

+

+--
+This terminates the list of options. It is useful if the next item on the
+command line starts with a hyphen but is not an option. This allows for the
+processing of patterns and file names that start with hyphens.
+

+

+-A number, --after-context=number
+Output up to number lines of context after each matching line. Fewer
+lines are output if the next match or the end of the file is reached, or if the
+processing buffer size has been set too small. If file names and/or line
+numbers are being output, a hyphen separator is used instead of a colon for the
+context lines (the -Z option can be used to change the file name
+terminator to a zero byte). A line containing "--" is output between each group
+of lines, unless they are in fact contiguous in the input file. The value of
+number is expected to be relatively small. When -c is used,
+-A is ignored.
+

+

+-a, --text
+Treat binary files as text. This is equivalent to
+--binary-files=text.
+

+

+--allow-lookaround-bsk
+PCRE2 now forbids the use of \K in lookarounds by default, in line with Perl.
+This option causes pcre2grep to set the PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK
+option, which enables this somewhat dangerous usage.
+

+

+-B number, --before-context=number
+Output up to number lines of context before each matching line. Fewer
+lines are output if the previous match or the start of the file is within
+number lines, or if the processing buffer size has been set too small. If
+file names and/or line numbers are being output, a hyphen separator is used
+instead of a colon for the context lines (the -Z option can be used to
+change the file name terminator to a zero byte). A line containing "--" is
+output between each group of lines, unless they are in fact contiguous in the
+input file. The value of number is expected to be relatively small. When
+-c is used, -B is ignored.
+

+

+--binary-files=word
+Specify how binary files are to be processed. If the word is "binary" (the
+default), pattern matching is performed on binary files, but the only output is
+"Binary file <name> matches" when a match succeeds. If the word is "text",
+which is equivalent to the -a or --text option, binary files are
+processed in the same way as any other file. In this case, when a match
+succeeds, the output may be binary garbage, which can have nasty effects if
+sent to a terminal. If the word is "without-match", which is equivalent to the
+-I option, binary files are not processed at all; they are assumed not to
+be of interest and are skipped without causing any output or affecting the
+return code.
+

+

+--buffer-size=number
+Set the parameter that controls how much memory is obtained at the start of
+processing for buffering files that are being scanned. See also
+--max-buffer-size below.
+

+

+-C number, --context=number
+Output number lines of context both before and after each matching line.
+This is equivalent to setting both -A and -B to the same value.
+

+

+-c, --count
+Do not output lines from the files that are being scanned; instead output the
+number of lines that would have been shown, either because they matched, or, if
+-v is set, because they failed to match. By default, this count is
+exactly the same as the number of lines that would have been output, but if the
+-M (multiline) option is used (without -v), there may be more
+suppressed lines than the count (that is, the number of matches).
+

+

+If no lines are selected, the number zero is output. If several files are
+being scanned, a count is output for each of them and the -t option can
+be used to cause a total to be output at the end. However, if the
+--files-with-matches option is also used, only those files whose counts
+are greater than zero are listed. When -c is used, the -A,
+-B, and -C options are ignored.
+

+

+--colour, --color
+If this option is given without any data, it is equivalent to "--colour=auto".
+If data is required, it must be given in the same shell item, separated by an
+equals sign.
+

+

+--colour=value, --color=value
+This option specifies under what circumstances the parts of a line that matched
+a pattern should be coloured in the output. It is ignored if
+--file-offsets, --line-offsets, or --output is set. By
+default, output is not coloured. The value for the --colour option (which
+is optional, see above) may be "never", "always", or "auto". In the latter
+case, colouring happens only if the standard output is connected to a terminal.
+More resources are used when colouring is enabled, because pcre2grep has
+to search for all possible matches in a line, not just one, in order to colour
+them all.
+

+

+The colour that is used can be specified by setting one of the environment
+variables PCRE2GREP_COLOUR, PCRE2GREP_COLOR, PCREGREP_COLOUR, or
+PCREGREP_COLOR, which are checked in that order. If none of these are set,
+pcre2grep looks for GREP_COLORS or GREP_COLOR (in that order). The value
+of the variable should be a string of two numbers, separated by a semicolon,
+except in the case of GREP_COLORS, which must start with "ms=" or "mt="
+followed by two semicolon-separated colours, terminated by the end of the
+string or by a colon. If GREP_COLORS does not start with "ms=" or "mt=" it is
+ignored, and GREP_COLOR is checked.
+

+

+If the string obtained from one of the above variables contains any characters
+other than semicolon or digits, the setting is ignored and the default colour
+is used. The string is copied directly into the control string for setting
+colour on a terminal, so it is your responsibility to ensure that the values
+make sense. If no relevant environment variable is set, the default is "1;31",
+which gives red.
+

+

+-D action, --devices=action
+If an input path is not a regular file or a directory, "action" specifies how
+it is to be processed. Valid values are "read" (the default) or "skip"
+(silently skip the path).
+

+

+-d action, --directories=action
+If an input path is a directory, "action" specifies how it is to be processed.
+Valid values are "read" (the default in non-Windows environments, for
+compatibility with GNU grep), "recurse" (equivalent to the -r option), or
+"skip" (silently skip the path, the default in Windows environments). In the
+"read" case, directories are read as if they were ordinary files. In some
+operating systems the effect of reading a directory like this is an immediate
+end-of-file; in others it may provoke an error.
+

+

+--depth-limit=number
+See --match-limit below.
+

+

+-E, --case-restrict
+When case distinctions are being ignored in Unicode mode, two ASCII letters (K
+and S) will by default match Unicode characters U+212A (Kelvin sign) and U+017F
+(long S) respectively, as well as their lower case ASCII counterparts. When
+this option is set, case equivalences are restricted such that no ASCII
+character matches a non-ASCII character, and vice versa.
+

+

+-e pattern, --regex=pattern, --regexp=pattern
+Specify a pattern to be matched. This option can be used multiple times in
+order to specify several patterns. It can also be used as a way of specifying a
+single pattern that starts with a hyphen. When -e is used, no argument
+pattern is taken from the command line; all arguments are treated as file
+names. There is no limit to the number of patterns. They are applied to each
+line in the order in which they are defined.
+

+

+If -f is used with -e, the command line patterns are matched first,
+followed by the patterns from the file(s), independent of the order in which
+these options are specified.
+

+

+--exclude=pattern
+Files (but not directories) whose names match the pattern are skipped without
+being processed. This applies to all files, whether listed on the command line,
+obtained from --file-list, or by scanning a directory. The pattern is a
+PCRE2 regular expression, and is matched against the final component of the
+file name, not the entire path. The -F, -w, and -x options do
+not apply to this pattern. The option may be given any number of times in order
+to specify multiple patterns. If a file name matches both an --include
+and an --exclude pattern, it is excluded. There is no short form for this
+option.
+

+

+--exclude-from=filename
+Treat each non-empty line of the file as the data for an --exclude
+option. What constitutes a newline when reading the file is the operating
+system's default. The --newline option has no effect on this option. This
+option may be given more than once in order to specify a number of files to
+read.
+

+

+--exclude-dir=pattern
+Directories whose names match the pattern are skipped without being processed,
+whatever the setting of the --recursive option. This applies to all
+directories, whether listed on the command line, obtained from
+--file-list, or by scanning a parent directory. The pattern is a PCRE2
+regular expression, and is matched against the final component of the directory
+name, not the entire path. The -F, -w, and -x options do not
+apply to this pattern. The option may be given any number of times in order to
+specify more than one pattern. If a directory matches both --include-dir
+and --exclude-dir, it is excluded. There is no short form for this
+option.
+

+

+-F, --fixed-strings
+Interpret each data-matching pattern as a list of fixed strings, separated by
+newlines, instead of as a regular expression. What constitutes a newline for
+this purpose is controlled by the --newline option. The -w (match
+as a word) and -x (match whole line) options can be used with -F.
+They apply to each of the fixed strings. A line is selected if any of the fixed
+strings are found in it (subject to -w or -x, if present). This
+option applies only to the patterns that are matched against the contents of
+files; it does not apply to patterns specified by any of the --include or
+--exclude options.
+

+

+-f filename, --file=filename
+Read patterns from the file, one per line. As is the case with patterns on the
+command line, no delimiters should be used. What constitutes a newline when
+reading the file is the operating system's default interpretation of \n. The
+--newline option has no effect on this option. Trailing white space is
+removed from each line, and blank lines are ignored. An empty file contains no
+patterns and therefore matches nothing. Patterns read from a file in this way
+may contain binary zeros, which are treated as ordinary data characters.
+

+

+If this option is given more than once, all the specified files are read. A
+data line is output if any of the patterns match it. A file name can be given
+as "-" to refer to the standard input. When -f is used, patterns
+specified on the command line using -e may also be present; they are
+matched before the file's patterns. However, no pattern is taken from the
+command line; all arguments are treated as the names of paths to be searched.
+

+

+--file-list=filename
+Read a list of files and/or directories that are to be scanned from the given
+file, one per line. What constitutes a newline when reading the file is the
+operating system's default. Trailing white space is removed from each line, and
+blank lines are ignored. These paths are processed before any that are listed
+on the command line. The file name can be given as "-" to refer to the standard
+input. If --file and --file-list are both specified as "-",
+patterns are read first. This is useful only when the standard input is a
+terminal, from which further lines (the list of files) can be read after an
+end-of-file indication. If this option is given more than once, all the
+specified files are read.
+

+

+--file-offsets
+Instead of showing lines or parts of lines that match, show each match as an
+offset from the start of the file and a length, separated by a comma. In this
+mode, --colour has no effect, and no context is shown. That is, the
+-A, -B, and -C options are ignored. If there is more than one
+match in a line, each of them is shown separately. This option is mutually
+exclusive with --output, --line-offsets, and --only-matching.
+

+

+--group-separator=text
+Output this text string instead of two hyphens between groups of lines when
+-A, -B, or -C is in use. See also --no-group-separator.
+

+

+-H, --with-filename
+Force the inclusion of the file name at the start of output lines when
+searching a single file. The file name is not normally shown in this case.
+By default, for matching lines, the file name is followed by a colon; for
+context lines, a hyphen separator is used. The -Z option can be used to
+change the terminator to a zero byte. If a line number is also being output,
+it follows the file name. When the -M option causes a pattern to match
+more than one line, only the first is preceded by the file name. This option
+overrides any previous -h, -l, or -L options.
+

+

+-h, --no-filename
+Suppress the output file names when searching multiple files. File names are
+normally shown when multiple files are searched. By default, for matching
+lines, the file name is followed by a colon; for context lines, a hyphen
+separator is used. The -Z option can be used to change the terminator to
+a zero byte. If a line number is also being output, it follows the file name.
+This option overrides any previous -H, -L, or -l options.
+

+

+--heap-limit=number
+See --match-limit below.
+

+

+--help
+Output a help message, giving brief details of the command options and file
+type support, and then exit. Anything else on the command line is
+ignored.
+

+

+-I
+Ignore binary files. This is equivalent to
+--binary-files=without-match.
+

+

+-i, --ignore-case
+Ignore upper/lower case distinctions when pattern matching. This applies when
+matching path names for inclusion or exclusion as well as when matching lines
+in files.
+

+

+--include=pattern
+If any --include patterns are specified, the only files that are
+processed are those whose names match one of the patterns and do not match an
+--exclude pattern. This option does not affect directories, but it
+applies to all files, whether listed on the command line, obtained from
+--file-list, or by scanning a directory. The pattern is a PCRE2 regular
+expression, and is matched against the final component of the file name, not
+the entire path. The -F, -w, and -x options do not apply to
+this pattern. The option may be given any number of times. If a file name
+matches both an --include and an --exclude pattern, it is excluded.
+There is no short form for this option.
+

+

+--include-from=filename
+Treat each non-empty line of the file as the data for an --include
+option. What constitutes a newline for this purpose is the operating system's
+default. The --newline option has no effect on this option. This option
+may be given any number of times; all the files are read.
+

+

+--include-dir=pattern
+If any --include-dir patterns are specified, the only directories that
+are processed are those whose names match one of the patterns and do not match
+an --exclude-dir pattern. This applies to all directories, whether listed
+on the command line, obtained from --file-list, or by scanning a parent
+directory. The pattern is a PCRE2 regular expression, and is matched against
+the final component of the directory name, not the entire path. The -F,
+-w, and -x options do not apply to this pattern. The option may be
+given any number of times. If a directory matches both --include-dir and
+--exclude-dir, it is excluded. There is no short form for this option.
+

+

+-L, --files-without-match
+Instead of outputting lines from the files, just output the names of the files
+that do not contain any lines that would have been output. Each file name is
+output once, on a separate line by default, but if the -Z option is set,
+they are separated by zero bytes instead of newlines. This option overrides any
+previous -H, -h, or -l options.
+

+

+-l, --files-with-matches
+Instead of outputting lines from the files, just output the names of the files
+containing lines that would have been output. Each file name is output once, on
+a separate line, but if the -Z option is set, they are separated by zero
+bytes instead of newlines. Searching normally stops as soon as a matching line
+is found in a file. However, if the -c (count) option is also used,
+matching continues in order to obtain the correct count, and those files that
+have at least one match are listed along with their counts. Using this option
+with -c is a way of suppressing the listing of files with no matches that
+occurs with -c on its own. This option overrides any previous -H,
+-h, or -L options.
+

+

+--label=name
+This option supplies a name to be used for the standard input when file names
+are being output. If not supplied, "(standard input)" is used. There is no
+short form for this option.
+

+

+--line-buffered
+When this option is given, non-compressed input is read and processed line by
+line, and the output is flushed after each write. By default, input is read in
+large chunks, unless pcre2grep can determine that it is reading from a
+terminal, which is currently possible only in Unix-like environments or
+Windows. Output to terminal is normally automatically flushed by the operating
+system. This option can be useful when the input or output is attached to a
+pipe and you do not want pcre2grep to buffer up large amounts of data.
+However, its use will affect performance, and the -M (multiline) option
+ceases to work. When input is from a compressed .gz or .bz2 file,
+--line-buffered is ignored.
+

+

+--line-offsets
+Instead of showing lines or parts of lines that match, show each match as a
+line number, the offset from the start of the line, and a length. The line
+number is terminated by a colon (as usual; see the -n option), and the
+offset and length are separated by a comma. In this mode, --colour has no
+effect, and no context is shown. That is, the -A, -B, and -C
+options are ignored. If there is more than one match in a line, each of them is
+shown separately. This option is mutually exclusive with --output,
+--file-offsets, and --only-matching.
+

+

+--locale=locale-name
+This option specifies a locale to be used for pattern matching. It overrides
+the value in the LC_ALL or LC_CTYPE environment variables. If no
+locale is specified, the PCRE2 library's default (usually the "C" locale) is
+used. There is no short form for this option.
+

+

+-M, --multiline
+Allow patterns to match more than one line. When this option is set, the PCRE2
+library is called in "multiline" mode, and a match is allowed to continue past
+the end of the initial line and onto one or more subsequent lines.
+

+

+Patterns used with -M may usefully contain literal newline characters and
+internal occurrences of ^ and $ characters, because in multiline mode these can
+match at internal newlines. Because pcre2grep is scanning multiple lines,
+the \Z and \z assertions match only at the end of the last line in the file.
+The \A assertion matches at the start of the first line of a match. This can
+be any line in the file; it is not anchored to the first line.
+

+

+The output for a successful match may consist of more than one line. The first
+line is the line in which the match started, and the last line is the line in
+which the match ended. If the matched string ends with a newline sequence, the
+output ends at the end of that line. If -v is set, none of the lines in a
+multi-line match are output. Once a match has been handled, scanning restarts
+at the beginning of the line after the one in which the match ended.
+

+

+The newline sequence that separates multiple lines must be matched as part of
+the pattern. For example, to find the phrase "regular expression" in a file
+where "regular" might be at the end of a line and "expression" at the start of
+the next line, you could use this command:
+
+  pcre2grep -M 'regular\s+expression' <file>
+

+The \s escape sequence matches any white space character, including newlines,
+and is followed by + so as to match trailing white space on the first line as
+well as possibly handling a two-character newline sequence.
+

+

+There is a limit to the number of lines that can be matched, imposed by the way
+that pcre2grep buffers the input file as it scans it. With a sufficiently
+large processing buffer, this should not be a problem.
+

+

+The -M option does not work when input is read line by line (see
+--line-buffered.)
+

+

+-m number, --max-count=number
+Stop processing after finding number matching lines, or non-matching
+lines if -v is also set. Any trailing context lines are output after the
+final match. In multiline mode, each multiline match counts as just one line
+for this purpose. If this limit is reached when reading the standard input from
+a regular file, the file is left positioned just after the last matching line.
+If -c is also set, the count that is output is never greater than
+number. This option has no effect if used with -L, -l, or
+-q, or when just checking for a match in a binary file.
+

+

+--match-limit=number
+Processing some regular expression patterns may take a very long time to search
+for all possible matching strings. Others may require a very large amount of
+memory. There are three options that set resource limits for matching.
+

+

+The --match-limit option provides a means of limiting computing resource
+usage when processing patterns that are not going to match, but which have a
+very large number of possibilities in their search trees. The classic example
+is a pattern that uses nested unlimited repeats. Internally, PCRE2 has a
+counter that is incremented each time around its main processing loop. If the
+value set by --match-limit is reached, an error occurs.
+

+

+The --heap-limit option specifies, as a number of kibibytes (units of
+1024 bytes), the maximum amount of heap memory that may be used for matching.
+

+

+The --depth-limit option limits the depth of nested backtracking points,
+which indirectly limits the amount of memory that is used. The amount of memory
+needed for each backtracking point depends on the number of capturing
+parentheses in the pattern, so the amount of memory that is used before this
+limit acts varies from pattern to pattern. This limit is of use only if it is
+set smaller than --match-limit.
+

+

+There are no short forms for these options. The default limits can be set
+when the PCRE2 library is compiled; if they are not specified, the defaults
+are very large and so effectively unlimited.
+

+

+--max-buffer-size=number
+This limits the expansion of the processing buffer, whose initial size can be
+set by --buffer-size. The maximum buffer size is silently forced to be no
+smaller than the starting buffer size.
+

+

+-N newline-type, --newline=newline-type
+Six different conventions for indicating the ends of lines in scanned files are
+supported. For example:
+
+  pcre2grep -N CRLF 'some pattern' <file>
+

+The newline type may be specified in upper, lower, or mixed case. If the
+newline type is NUL, lines are separated by binary zero characters. The other
+types are the single-character sequences CR (carriage return) and LF
+(linefeed), the two-character sequence CRLF, an "anycrlf" type, which
+recognizes any of the preceding three types, and an "any" type, for which any
+Unicode line ending sequence is assumed to end a line. The Unicode sequences
+are the three just mentioned, plus VT (vertical tab, U+000B), FF (form feed,
+U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and PS
+(paragraph separator, U+2029).
+

+

+When the PCRE2 library is built, a default line-ending sequence is specified.
+This is normally the standard sequence for the operating system. Unless
+otherwise specified by this option, pcre2grep uses the library's default.
+

+

+This option makes it possible to use pcre2grep to scan files that have
+come from other environments without having to modify their line endings. If
+the data that is being scanned does not agree with the convention set by this
+option, pcre2grep may behave in strange ways. Note that this option does
+not apply to files specified by the -f, --exclude-from, or
+--include-from options, which are expected to use the operating system's
+standard newline sequence.
+

+

+-n, --line-number
+Precede each output line by its line number in the file, followed by a colon
+for matching lines or a hyphen for context lines. If the file name is also
+being output, it precedes the line number. When the -M option causes a
+pattern to match more than one line, only the first is preceded by its line
+number. This option is forced if --line-offsets is used.
+

+

+--no-group-separator
+Do not output a separator between groups of lines when -A, -B, or
+-C is in use. The default is to output a line containing two hyphens. See
+also --group-separator.
+

+

+--no-jit
+If the PCRE2 library is built with support for just-in-time compiling (which
+speeds up matching), pcre2grep automatically makes use of this, unless it
+was explicitly disabled at build time. This option can be used to disable the
+use of JIT at run time. It is provided for testing and working around problems.
+It should never be needed in normal use.
+

+

+-O text, --output=text
+When there is a match, instead of outputting the line that matched, output just
+the text specified in this option, followed by an operating-system standard
+newline. In this mode, --colour has no effect, and no context is shown.
+That is, the -A, -B, and -C options are ignored. The
+--newline option has no effect on this option, which is mutually
+exclusive with --only-matching, --file-offsets, and
+--line-offsets. However, like --only-matching, if there is more
+than one match in a line, each of them causes a line of output.
+

+

+Escape sequences starting with a dollar character may be used to insert the
+contents of the matched part of the line and/or captured substrings into the
+text.
+

+

+$<digits> or ${<digits>} is replaced by the captured substring of the given
+decimal number; zero substitutes the whole match. If the number is greater than
+the number of capturing substrings, or if the capture is unset, the replacement
+is empty.
+

+

+$a is replaced by bell; $b by backspace; $e by escape; $f by form feed; $n by
+newline; $r by carriage return; $t by tab; $v by vertical tab.
+

+

+$o<digits> or $o{<digits>} is replaced by the character whose code point is the
+given octal number. In the first form, up to three octal digits are processed.
+When more digits are needed in Unicode mode to specify a wide character, the
+second form must be used.
+

+

+$x<digits> or $x{<digits>} is replaced by the character represented by the
+given hexadecimal number. In the first form, up to two hexadecimal digits are
+processed. When more digits are needed in Unicode mode to specify a wide
+character, the second form must be used.
+

+

+Any other character is substituted by itself. In particular, $$ is replaced by
+a single dollar.
+

+

+-o, --only-matching
+Show only the part of the line that matched a pattern instead of the whole
+line. In this mode, no context is shown. That is, the -A, -B, and
+-C options are ignored. If there is more than one match in a line, each
+of them is shown separately, on a separate line of output. If -o is
+combined with -v (invert the sense of the match to find non-matching
+lines), no output is generated, but the return code is set appropriately. If
+the matched portion of the line is empty, nothing is output unless the file
+name or line number are being printed, in which case they are shown on an
+otherwise empty line. This option is mutually exclusive with --output,
+--file-offsets and --line-offsets.
+

+

+-onumber, --only-matching=number
+Show only the part of the line that matched the capturing parentheses of the
+given number. Up to 50 capturing parentheses are supported by default. This
+limit can be changed via the --om-capture option. A pattern may contain
+any number of capturing parentheses, but only those whose number is within the
+limit can be accessed by -o. An error occurs if the number specified by
+-o is greater than the limit.
+

+

+-o0 is the same as -o without a number. Because these options can be
+given without an argument (see above), if an argument is present, it must be
+given in the same shell item, for example, -o3 or --only-matching=2. The
+comments given for the non-argument case above also apply to this option. If
+the specified capturing parentheses do not exist in the pattern, or were not
+set in the match, nothing is output unless the file name or line number are
+being output.
+

+

+If this option is given multiple times, multiple substrings are output for each
+match, in the order the options are given, and all on one line. For example,
+-o3 -o1 -o3 causes the substrings matched by capturing parentheses 3 and 1 and
+then 3 again to be output. By default, there is no separator (but see the next
+but one option).
+

+

+--om-capture=number
+Set the number of capturing parentheses that can be accessed by -o. The
+default is 50.
+

+

+--om-separator=text
+Specify a separating string for multiple occurrences of -o. The default
+is an empty string. Separating strings are never coloured.
+

+

+-P, --no-ucp
+Starting from release 10.43, when UTF/Unicode mode is specified with -u
+or -U, the PCRE2_UCP option is used by default. This means that the
+POSIX classes in patterns match more than just ASCII characters. For example,
+[:digit:] matches any Unicode decimal digit. The --no-ucp option
+suppresses PCRE2_UCP, thus restricting the POSIX classes to ASCII characters,
+as was the case in earlier releases. Note that there are now more fine-grained
+option settings within patterns that affect individual classes. For example,
+when in UCP mode, the sequence (?aP) restricts [:word:] to ASCII letters, while
+allowing \w to match Unicode letters and digits.
+

+

+-q, --quiet
+Work quietly, that is, display nothing except error messages. The exit
+status indicates whether or not any matches were found.
+

+

+-r, --recursive
+If any given path is a directory, recursively scan the files it contains,
+taking note of any --include and --exclude settings. By default, a
+directory is read as a normal file; in some operating systems this gives an
+immediate end-of-file. This option is a shorthand for setting the -d
+option to "recurse".
+

+

+--recursion-limit=number
+This is an obsolete synonym for --depth-limit. See --match-limit
+above for details.
+

+

+-s, --no-messages
+Suppress error messages about non-existent or unreadable files. Such files are
+quietly skipped. However, the return code is still 2, even if matches were
+found in other files.
+

+

+-t, --total-count
+This option is useful when scanning more than one file. If used on its own,
+-t suppresses all output except for a grand total number of matching
+lines (or non-matching lines if -v is used) in all the files. If -t
+is used with -c, a grand total is output except when the previous output
+is just one line. In other words, it is not output when just one file's count
+is listed. If file names are being output, the grand total is preceded by
+"TOTAL:". Otherwise, it appears as just another number. The -t option is
+ignored when used with -L (list files without matches), because the grand
+total would always be zero.
+

+

+-u, --utf
+Operate in UTF/Unicode mode. This option is available only if PCRE2 has been
+compiled with UTF-8 support. All patterns (including those for any
+--exclude and --include options) and all lines that are scanned
+must be valid strings of UTF-8 characters. If an invalid UTF-8 string is
+encountered, an error occurs.
+

+

+-U, --utf-allow-invalid
+As --utf, but in addition subject lines may contain invalid UTF-8 code
+unit sequences. These can never form part of any pattern match. Patterns
+themselves, however, must still be valid UTF-8 strings. This facility allows
+valid UTF-8 strings to be sought within arbitrary byte sequences in executable
+or other binary files. For more details about matching in non-valid UTF-8
+strings, see the
+pcre2unicode(3)
+documentation.
+

+

+-V, --version
+Write the version numbers of pcre2grep and the PCRE2 library to the
+standard output and then exit. Anything else on the command line is
+ignored.
+

+

+-v, --invert-match
+Invert the sense of the match, so that lines which do not match any of
+the patterns are the ones that are found. When this option is set, options such
+as --only-matching and --output, which specify parts of a match
+that are to be output, are ignored.
+

+

+-w, --word-regex, --word-regexp
+Force the patterns only to match "words". That is, there must be a word
+boundary at the start and end of each matched string. This is equivalent to
+having "\b(?:" at the start of each pattern, and ")\b" at the end. This
+option applies only to the patterns that are matched against the contents of
+files; it does not apply to patterns specified by any of the --include or
+--exclude options.
+

+

+-x, --line-regex, --line-regexp
+Force the patterns to start matching only at the beginnings of lines, and in
+addition, require them to match entire lines. In multiline mode the match may
+be more than one line. This is equivalent to having "^(?:" at the start of each
+pattern and ")$" at the end. This option applies only to the patterns that are
+matched against the contents of files; it does not apply to patterns specified
+by any of the --include or --exclude options.
+

+

+-Z, --null
+Terminate files names in the regular output with a zero byte (the NUL
+character) instead of what would normally appear. This is useful when file
+names contain unusual characters such as colons, hyphens, or even newlines. The
+option does not apply to file names in error messages.
+

+
ENVIRONMENT VARIABLES

+

+The environment variables LC_ALL and LC_CTYPE are examined, in that
+order, for a locale. The first one that is set is used. This can be overridden
+by the --locale option. If no locale is set, the PCRE2 library's default
+(usually the "C" locale) is used.
+

+
NEWLINES

+

+The -N (--newline) option allows pcre2grep to scan files with
+newline conventions that differ from the default. This option affects only the
+way scanned files are processed. It does not affect the interpretation of files
+specified by the -f, --file-list, --exclude-from, or
+--include-from options.
+

+

+Any parts of the scanned input files that are written to the standard output
+are copied with whatever newline sequences they have in the input. However, if
+the final line of a file is output, and it does not end with a newline
+sequence, a newline sequence is added. If the newline setting is CR, LF, CRLF
+or NUL, that line ending is output; for the other settings (ANYCRLF or ANY) a
+single NL is used.
+

+

+The newline setting does not affect the way in which pcre2grep writes
+newlines in informational messages to the standard output and error streams.
+Under Windows, the standard output is set to be binary, so that "\r\n" at the
+ends of output lines that are copied from the input is not converted to
+"\r\r\n" by the C I/O library. This means that any messages written to the
+standard output must end with "\r\n". For all other operating systems, and
+for all messages to the standard error stream, "\n" is used.
+

+
OPTIONS COMPATIBILITY WITH GNU GREP

+

+Many of the short and long forms of pcre2grep's options are the same as
+in the GNU grep program. Any long option of the form --xxx-regexp
+(GNU terminology) is also available as --xxx-regex (PCRE2 terminology).
+However, the --case-restrict, --depth-limit, -E,
+--file-list, --file-offsets, --heap-limit,
+--include-dir, --line-offsets, --locale, --match-limit,
+-M, --multiline, -N, --newline, --no-ucp,
+--om-separator, --output, -P, -u, --utf,
+-U, and --utf-allow-invalid options are specific to
+pcre2grep, as is the use of the --only-matching option with a
+capturing parentheses number.
+

+

+Although most of the common options work the same way, a few are different in
+pcre2grep. For example, the --include option's argument is a glob
+for GNU grep, but in pcre2grep it is a regular expression to which
+the -i option applies. If both the -c and -l options are
+given, GNU grep lists only file names, without counts, but pcre2grep
+gives the counts as well.
+

+
OPTIONS WITH DATA

+

+There are four different ways in which an option with data can be specified.
+If a short form option is used, the data may follow immediately, or (with one
+exception) in the next command line item. For example:
+
+  -f/some/file
+  -f /some/file
+

+The exception is the -o option, which may appear with or without data.
+Because of this, if data is present, it must follow immediately in the same
+item, for example -o3.
+

+

+If a long form option is used, the data may appear in the same command line
+item, separated by an equals character, or (with two exceptions) it may appear
+in the next command line item. For example:
+
+  --file=/some/file
+  --file /some/file
+

+Note, however, that if you want to supply a file name beginning with ~ as data
+in a shell command, and have the shell expand ~ to a home directory, you must
+separate the file name from the option, because the shell does not treat ~
+specially unless it is at the start of an item.
+

+

+The exceptions to the above are the --colour (or --color) and
+--only-matching options, for which the data is optional. If one of these
+options does have data, it must be given in the first form, using an equals
+character. Otherwise pcre2grep will assume that it has no data.
+

+
USING PCRE2'S CALLOUT FACILITY

+

+pcre2grep has, by default, support for calling external programs or
+scripts or echoing specific strings during matching by making use of PCRE2's
+callout facility. However, this support can be completely or partially disabled
+when pcre2grep is built. You can find out whether your binary has support
+for callouts by running it with the --help option. If callout support is
+completely disabled, all callouts in patterns are ignored by pcre2grep.
+If the facility is partially disabled, calling external programs is not
+supported, and callouts that request it are ignored.
+

+

+A callout in a PCRE2 pattern is of the form (?C<arg>) where the argument is
+either a number or a quoted string (see the
+pcre2callout
+documentation for details). Numbered callouts are ignored by pcre2grep;
+only callouts with string arguments are useful.
+

+

+Echoing a specific string
+

+

+Starting the callout string with a pipe character invokes an echoing facility
+that avoids calling an external program or script. This facility is always
+available, provided that callouts were not completely disabled when
+pcre2grep was built. The rest of the callout string is processed as a
+zero-terminated string, which means it should not contain any internal binary
+zeros. It is written to the output, having first been passed through the same
+escape processing as text from the --output (-O) option (see
+above). However, $0 cannot be used to insert a matched substring because the
+match is still in progress. Instead, the single character '0' is inserted. Any
+syntax errors in the string (for example, a dollar not followed by another
+character) causes the callout to be ignored. No terminator is added to the
+output string, so if you want a newline, you must include it explicitly using
+the escape $n. For example:
+
+  pcre2grep '(.)(..(.))(?C"|[$1] [$2] [$3]$n")' <some file>
+

+Matching continues normally after the string is output. If you want to see only
+the callout output but not any output from an actual match, you should end the
+pattern with (*FAIL).
+

+

+Calling external programs or scripts
+

+

+This facility can be independently disabled when pcre2grep is built. It
+is supported for Windows, where a call to _spawnvp() is used, for VMS,
+where lib$spawn() is used, and for any Unix-like environment where
+fork() and execv() are available.
+

+

+If the callout string does not start with a pipe (vertical bar) character, it
+is parsed into a list of substrings separated by pipe characters. The first
+substring must be an executable name, with the following substrings specifying
+arguments:
+
+  executable_name|arg1|arg2|...
+

+Any substring (including the executable name) may contain escape sequences
+started by a dollar character. These are the same as for the --output
+(-O) option documented above, except that $0 cannot insert the matched
+string because the match is still in progress. Instead, the character '0'
+is inserted. If you need a literal dollar or pipe character in any
+substring, use $$ or $| respectively. Here is an example:
+
+  echo -e "abcde\n12345" | pcre2grep \
+    '(?x)(.)(..(.))
+    (?C"/bin/echo|Arg1: [$1] [$2] [$3]|Arg2: $|${1}$| ($4)")()' -
+
+  Output:
+
+    Arg1: [a] [bcd] [d] Arg2: |a| ()
+    abcde
+    Arg1: [1] [234] [4] Arg2: |1| ()
+    12345
+

+The parameters for the system call that is used to run the program or script
+are zero-terminated strings. This means that binary zero characters in the
+callout argument will cause premature termination of their substrings, and
+therefore should not be present. Any syntax errors in the string (for example,
+a dollar not followed by another character) causes the callout to be ignored.
+If running the program fails for any reason (including the non-existence of the
+executable), a local matching failure occurs and the matcher backtracks in the
+normal way.
+

+
MATCHING ERRORS

+

+It is possible to supply a regular expression that takes a very long time to
+fail to match certain lines. Such patterns normally involve nested indefinite
+repeats, for example: (a+)*\d when matched against a line of a's with no final
+digit. The PCRE2 matching function has a resource limit that causes it to abort
+in these circumstances. If this happens, pcre2grep outputs an error
+message and the line that caused the problem to the standard error stream. If
+there are more than 20 such errors, pcre2grep gives up.
+

+

+The --match-limit option of pcre2grep can be used to set the
+overall resource limit. There are also other limits that affect the amount of
+memory used during matching; see the discussion of --heap-limit and
+--depth-limit above.
+

+
DIAGNOSTICS

+

+Exit status is 0 if any matches were found, 1 if no matches were found, and 2
+for syntax errors, overlong lines, non-existent or inaccessible files (even if
+matches were found in other files) or too many matching errors. Using the
+-s option to suppress error messages about inaccessible files does not
+affect the return code.
+

+

+When run under VMS, the return code is placed in the symbol PCRE2GREP_RC
+because VMS does not distinguish between exit(0) and exit(1).

PCRE2 JUST-IN-TIME COMPILER SUPPORT

+

+Just-in-time compiling is a heavyweight optimization that can greatly speed up
+pattern matching. However, it comes at the cost of extra processing before the
+match is performed, so it is of most benefit when the same pattern is going to
+be matched many times. This does not necessarily mean many calls of a matching
+function; if the pattern is not anchored, matching attempts may take place many
+times at various positions in the subject, even for a single call. Therefore,
+if the subject string is very long, it may still pay to use JIT even for
+one-off matches. JIT support is available for all of the 8-bit, 16-bit and
+32-bit PCRE2 libraries.
+

+

+JIT support applies only to the traditional Perl-compatible matching function.
+It does not apply when the DFA matching function is being used. The code for
+JIT support was written by Zoltan Herczeg.
+

+
AVAILABILITY OF JIT SUPPORT

+

+JIT support is an optional feature of PCRE2. The "configure" option
+--enable-jit (or equivalent CMake option) must be set when PCRE2 is built if
+you want to use JIT. The support is limited to the following hardware
+platforms:
+
+  ARM 32-bit (v7, and Thumb2)
+  ARM 64-bit
+  IBM s390x 64 bit
+  Intel x86 32-bit and 64-bit
+  LoongArch 64 bit
+  MIPS 32-bit and 64-bit
+  Power PC 32-bit and 64-bit
+  RISC-V 32-bit and 64-bit
+

+If --enable-jit is set on an unsupported platform, compilation fails.
+

+

+A client program can tell if JIT support is available by calling
+pcre2_config() with the PCRE2_CONFIG_JIT option. The result is one if
+PCRE2 was built with JIT support, and zero otherwise. However, having the JIT
+code available does not guarantee that it will be used for any particular
+match. One reason for this is that there are a number of options and pattern
+items that are
+not supported by JIT
+(see below). Another reason is that in some environments JIT is unable to get
+memory in which to build its compiled code. The only guarantee from
+pcre2_config() is that if it returns zero, JIT will definitely not
+be used.
+

+

+A simple program does not need to check availability in order to use JIT when
+possible. The API is implemented in a way that falls back to the interpretive
+code if JIT is not available or cannot be used for a given match. For programs
+that need the best possible performance, there is a
+"fast path"
+API that is JIT-specific.
+

+
SIMPLE USE OF JIT

+

+To make use of the JIT support in the simplest way, all you have to do is to
+call pcre2_jit_compile() after successfully compiling a pattern with
+pcre2_compile(). This function has two arguments: the first is the
+compiled pattern pointer that was returned by pcre2_compile(), and the
+second is zero or more of the following option bits: PCRE2_JIT_COMPLETE,
+PCRE2_JIT_PARTIAL_HARD, or PCRE2_JIT_PARTIAL_SOFT.
+

+

+If JIT support is not available, a call to pcre2_jit_compile() does
+nothing and returns PCRE2_ERROR_JIT_BADOPTION. Otherwise, the compiled pattern
+is passed to the JIT compiler, which turns it into machine code that executes
+much faster than the normal interpretive code, but yields exactly the same
+results. The returned value from pcre2_jit_compile() is zero on success,
+or a negative error code.
+

+

+There is a limit to the size of pattern that JIT supports, imposed by the size
+of machine stack that it uses. The exact rules are not documented because they
+may change at any time, in particular, when new optimizations are introduced.
+If a pattern is too big, a call to pcre2_jit_compile() returns
+PCRE2_ERROR_NOMEMORY.
+

+

+PCRE2_JIT_COMPLETE requests the JIT compiler to generate code for complete
+matches. If you want to run partial matches using the PCRE2_PARTIAL_HARD or
+PCRE2_PARTIAL_SOFT options of pcre2_match(), you should set one or both
+of the other options as well as, or instead of PCRE2_JIT_COMPLETE. The JIT
+compiler generates different optimized code for each of the three modes
+(normal, soft partial, hard partial). When pcre2_match() is called, the
+appropriate code is run if it is available. Otherwise, the pattern is matched
+using interpretive code.
+

+

+You can call pcre2_jit_compile() multiple times for the same compiled
+pattern. It does nothing if it has previously compiled code for any of the
+option bits. For example, you can call it once with PCRE2_JIT_COMPLETE and
+(perhaps later, when you find you need partial matching) again with
+PCRE2_JIT_COMPLETE and PCRE2_JIT_PARTIAL_HARD. This time it will ignore
+PCRE2_JIT_COMPLETE and just compile code for partial matching. If
+pcre2_jit_compile() is called with no option bits set, it immediately
+returns zero. This is an alternative way of testing whether JIT is available.
+

+

+At present, it is not possible to free JIT compiled code except when the entire
+compiled pattern is freed by calling pcre2_code_free().
+

+

+In some circumstances you may need to call additional functions. These are
+described in the section entitled
+"Controlling the JIT stack"
+below.
+

+

+There are some pcre2_match() options that are not supported by JIT, and
+there are also some pattern items that JIT cannot handle. Details are given
+below.
+In both cases, matching automatically falls back to the interpretive code. If
+you want to know whether JIT was actually used for a particular match, you
+should arrange for a JIT callback function to be set up as described in the
+section entitled
+"Controlling the JIT stack"
+below, even if you do not need to supply a non-default JIT stack. Such a
+callback function is called whenever JIT code is about to be obeyed. If the
+match-time options are not right for JIT execution, the callback function is
+not obeyed.
+

+

+If the JIT compiler finds an unsupported item, no JIT data is generated. You
+can find out if JIT compilation was successful for a compiled pattern by
+calling pcre2_pattern_info() with the PCRE2_INFO_JITSIZE option. A
+non-zero result means that JIT compilation was successful. A result of 0 means
+that JIT support is not available, or the pattern was not processed by
+pcre2_jit_compile(), or the JIT compiler was not able to handle the
+pattern. Successful JIT compilation does not, however, guarantee the use of JIT
+at match time because there are some match time options that are not supported
+by JIT.
+

+
MATCHING SUBJECTS CONTAINING INVALID UTF

+

+When a pattern is compiled with the PCRE2_UTF option, subject strings are
+normally expected to be a valid sequence of UTF code units. By default, this is
+checked at the start of matching and an error is generated if invalid UTF is
+detected. The PCRE2_NO_UTF_CHECK option can be passed to pcre2_match() to
+skip the check (for improved performance) if you are sure that a subject string
+is valid. If this option is used with an invalid string, the result is
+undefined. The calling program may crash or loop or otherwise misbehave.
+

+

+However, a way of running matches on strings that may contain invalid UTF
+sequences is available. Calling pcre2_compile() with the
+PCRE2_MATCH_INVALID_UTF option has two effects: it tells the interpreter in
+pcre2_match() to support invalid UTF, and, if pcre2_jit_compile()
+is subsequently called, the compiled JIT code also supports invalid UTF.
+Details of how this support works, in both the JIT and the interpretive cases,
+is given in the
+pcre2unicode
+documentation.
+

+

+There is also an obsolete option for pcre2_jit_compile() called
+PCRE2_JIT_INVALID_UTF, which currently exists only for backward compatibility.
+It is superseded by the pcre2_compile() option PCRE2_MATCH_INVALID_UTF
+and should no longer be used. It may be removed in future.
+

+
UNSUPPORTED OPTIONS AND PATTERN ITEMS

+

+The pcre2_match() options that are supported for JIT matching are
+PCRE2_COPY_MATCHED_SUBJECT, PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY,
+PCRE2_NOTEMPTY_ATSTART, PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD, and
+PCRE2_PARTIAL_SOFT. The PCRE2_ANCHORED and PCRE2_ENDANCHORED options are not
+supported at match time.
+

+

+If the PCRE2_NO_JIT option is passed to pcre2_match() it disables the
+use of JIT, forcing matching by the interpreter code.
+

+

+The only unsupported pattern items are \C (match a single data unit) when
+running in a UTF mode, and a callout immediately before an assertion condition
+in a conditional group.
+

+
RETURN VALUES FROM JIT MATCHING

+

+When a pattern is matched using JIT, the return values are the same as those
+given by the interpretive pcre2_match() code, with the addition of one
+new error code: PCRE2_ERROR_JIT_STACKLIMIT. This means that the memory used for
+the JIT stack was insufficient. See
+"Controlling the JIT stack"
+below for a discussion of JIT stack usage.
+

+

+The error code PCRE2_ERROR_MATCHLIMIT is returned by the JIT code if searching
+a very large pattern tree goes on for too long, as it is in the same
+circumstance when JIT is not used, but the details of exactly what is counted
+are not the same. The PCRE2_ERROR_DEPTHLIMIT error code is never returned
+when JIT matching is used.
+

+
CONTROLLING THE JIT STACK

+

+When the compiled JIT code runs, it needs a block of memory to use as a stack.
+By default, it uses 32KiB on the machine stack. However, some large or
+complicated patterns need more than this. The error PCRE2_ERROR_JIT_STACKLIMIT
+is given when there is not enough stack. Three functions are provided for
+managing blocks of memory for use as JIT stacks. There is further discussion
+about the use of JIT stacks in the section entitled
+"JIT stack FAQ"
+below.
+

+

+The pcre2_jit_stack_create() function creates a JIT stack. Its arguments
+are a starting size, a maximum size, and a general context (for memory
+allocation functions, or NULL for standard memory allocation). It returns a
+pointer to an opaque structure of type pcre2_jit_stack, or NULL if there
+is an error. The pcre2_jit_stack_free() function is used to free a stack
+that is no longer needed. If its argument is NULL, this function returns
+immediately, without doing anything. (For the technically minded: the address
+space is allocated by mmap or VirtualAlloc.) A maximum stack size of 512KiB to
+1MiB should be more than enough for any pattern.
+

+

+The pcre2_jit_stack_assign() function specifies which stack JIT code
+should use. Its arguments are as follows:
+
+  pcre2_match_context  *mcontext
+  pcre2_jit_callback    callback
+  void                 *data
+

+The first argument is a pointer to a match context. When this is subsequently
+passed to a matching function, its information determines which JIT stack is
+used. If this argument is NULL, the function returns immediately, without doing
+anything. There are three cases for the values of the other two options:
+
+  (1) If callback is NULL and data is NULL, an internal 32KiB block
+      on the machine stack is used. This is the default when a match
+      context is created.
+
+  (2) If callback is NULL and data is not NULL, data must be
+      a pointer to a valid JIT stack, the result of calling
+      pcre2_jit_stack_create().
+
+  (3) If callback is not NULL, it must point to a function that is
+      called with data as an argument at the start of matching, in
+      order to set up a JIT stack. If the return from the callback
+      function is NULL, the internal 32KiB stack is used; otherwise the
+      return value must be a valid JIT stack, the result of calling
+      pcre2_jit_stack_create().
+

+A callback function is obeyed whenever JIT code is about to be run; it is not
+obeyed when pcre2_match() is called with options that are incompatible
+for JIT matching. A callback function can therefore be used to determine
+whether a match operation was executed by JIT or by the interpreter.
+

+

+You may safely use the same JIT stack for more than one pattern (either by
+assigning directly or by callback), as long as the patterns are matched
+sequentially in the same thread. Currently, the only way to set up
+non-sequential matches in one thread is to use callouts: if a callout function
+starts another match, that match must use a different JIT stack to the one used
+for currently suspended match(es).
+

+

+In a multithread application, if you do not specify a JIT stack, or if you
+assign or pass back NULL from a callback, that is thread-safe, because each
+thread has its own machine stack. However, if you assign or pass back a
+non-NULL JIT stack, this must be a different stack for each thread so that the
+application is thread-safe.
+

+

+Strictly speaking, even more is allowed. You can assign the same non-NULL stack
+to a match context that is used by any number of patterns, as long as they are
+not used for matching by multiple threads at the same time. For example, you
+could use the same stack in all compiled patterns, with a global mutex in the
+callback to wait until the stack is available for use. However, this is an
+inefficient solution, and not recommended.
+

+

+This is a suggestion for how a multithreaded program that needs to set up
+non-default JIT stacks might operate:
+
+  During thread initialization
+    thread_local_var = pcre2_jit_stack_create(...)
+
+  During thread exit
+    pcre2_jit_stack_free(thread_local_var)
+
+  Use a one-line callback function
+    return thread_local_var
+

+All the functions described in this section do nothing if JIT is not available.
+

+
JIT STACK FAQ

+

+(1) Why do we need JIT stacks?
+

+

+PCRE2 (and JIT) is a recursive, depth-first engine, so it needs a stack where
+the local data of the current node is pushed before checking its child nodes.
+Allocating real machine stack on some platforms is difficult. For example, the
+stack chain needs to be updated every time if we extend the stack on PowerPC.
+Although it is possible, its updating time overhead decreases performance. So
+we do the recursion in memory.
+

+

+(2) Why don't we simply allocate blocks of memory with malloc()?
+

+

+Modern operating systems have a nice feature: they can reserve an address space
+instead of allocating memory. We can safely allocate memory pages inside this
+address space, so the stack could grow without moving memory data (this is
+important because of pointers). Thus we can allocate 1MiB address space, and
+use only a single memory page (usually 4KiB) if that is enough. However, we can
+still grow up to 1MiB anytime if needed.
+

+

+(3) Who "owns" a JIT stack?
+

+

+The owner of the stack is the user program, not the JIT studied pattern or
+anything else. The user program must ensure that if a stack is being used by
+pcre2_match(), (that is, it is assigned to a match context that is passed
+to the pattern currently running), that stack must not be used by any other
+threads (to avoid overwriting the same memory area). The best practice for
+multithreaded programs is to allocate a stack for each thread, and return this
+stack through the JIT callback function.
+

+

+(4) When should a JIT stack be freed?
+

+

+You can free a JIT stack at any time, as long as it will not be used by
+pcre2_match() again. When you assign the stack to a match context, only a
+pointer is set. There is no reference counting or any other magic. You can free
+compiled patterns, contexts, and stacks in any order, anytime.
+Just do not call pcre2_match() with a match context pointing to an
+already freed stack, as that will cause SEGFAULT. (Also, do not free a stack
+currently used by pcre2_match() in another thread). You can also replace
+the stack in a context at any time when it is not in use. You should free the
+previous stack before assigning a replacement.
+

+

+(5) Should I allocate/free a stack every time before/after calling
+pcre2_match()?
+

+

+No, because this is too costly in terms of resources. However, you could
+implement some clever idea which release the stack if it is not used in let's
+say two minutes. The JIT callback can help to achieve this without keeping a
+list of patterns.
+

+

+(6) OK, the stack is for long term memory allocation. But what happens if a
+pattern causes stack overflow with a stack of 1MiB? Is that 1MiB kept until the
+stack is freed?
+

+

+Especially on embedded systems, it might be a good idea to release memory
+sometimes without freeing the stack. There is no API for this at the moment.
+Probably a function call which returns with the currently allocated memory for
+any stack and another which allows releasing memory (shrinking the stack) would
+be a good idea if someone needs this.
+

+

+(7) This is too much of a headache. Isn't there any better solution for JIT
+stack handling?
+

+

+No, thanks to Windows. If POSIX threads were used everywhere, we could throw
+out this complicated API.
+

+
FREEING JIT SPECULATIVE MEMORY

+

+void pcre2_jit_free_unused_memory(pcre2_general_context *gcontext);
+

+

+The JIT executable allocator does not free all memory when it is possible. It
+expects new allocations, and keeps some free memory around to improve
+allocation speed. However, in low memory conditions, it might be better to free
+all possible memory. You can cause this to happen by calling
+pcre2_jit_free_unused_memory(). Its argument is a general context, for custom
+memory management, or NULL for standard memory management.
+

+
EXAMPLE CODE

+

+This is a single-threaded example that specifies a JIT stack without using a
+callback. A real program should include error checking after all the function
+calls.
+
+  int rc;
+  pcre2_code *re;
+  pcre2_match_data *match_data;
+  pcre2_match_context *mcontext;
+  pcre2_jit_stack *jit_stack;
+
+  re = pcre2_compile(pattern, PCRE2_ZERO_TERMINATED, 0,
+    &errornumber, &erroffset, NULL);
+  rc = pcre2_jit_compile(re, PCRE2_JIT_COMPLETE);
+  mcontext = pcre2_match_context_create(NULL);
+  jit_stack = pcre2_jit_stack_create(32*1024, 512*1024, NULL);
+  pcre2_jit_stack_assign(mcontext, NULL, jit_stack);
+  match_data = pcre2_match_data_create(re, 10);
+  rc = pcre2_match(re, subject, length, 0, 0, match_data, mcontext);
+  /* Process result */
+
+  pcre2_code_free(re);
+  pcre2_match_data_free(match_data);
+  pcre2_match_context_free(mcontext);
+  pcre2_jit_stack_free(jit_stack);
+
+

+

+
JIT FAST PATH API

+

+Because the API described above falls back to interpreted matching when JIT is
+not available, it is convenient for programs that are written for general use
+in many environments. However, calling JIT via pcre2_match() does have a
+performance impact. Programs that are written for use where JIT is known to be
+available, and which need the best possible performance, can instead use a
+"fast path" API to call JIT matching directly instead of calling
+pcre2_match() (obviously only for patterns that have been successfully
+processed by pcre2_jit_compile()).
+

+

+The fast path function is called pcre2_jit_match(), and it takes exactly
+the same arguments as pcre2_match(). However, the subject string must be
+specified with a length; PCRE2_ZERO_TERMINATED is not supported. Unsupported
+option bits (for example, PCRE2_ANCHORED and PCRE2_ENDANCHORED) are ignored, as
+is the PCRE2_NO_JIT option. The return values are also the same as for
+pcre2_match(), plus PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial
+or complete) is requested that was not compiled.
+

+

+When you call pcre2_match(), as well as testing for invalid options, a
+number of other sanity checks are performed on the arguments. For example, if
+the subject pointer is NULL but the length is non-zero, an immediate error is
+given. Also, unless PCRE2_NO_UTF_CHECK is set, a UTF subject string is tested
+for validity. In the interests of speed, these checks do not happen on the JIT
+fast path. If invalid UTF data is passed when PCRE2_MATCH_INVALID_UTF was not
+set for pcre2_compile(), the result is undefined. The program may crash
+or loop or give wrong results. In the absence of PCRE2_MATCH_INVALID_UTF you
+should call pcre2_jit_match() in UTF mode only if you are sure the
+subject is valid.
+

+

+Bypassing the sanity checks and the pcre2_match() wrapping can give
+speedups of more than 10%.

+SIZE AND OTHER LIMITATIONS
+

+

+There are some size limitations in PCRE2 but it is hoped that they will never
+in practice be relevant.
+

+

+The maximum size of a compiled pattern is approximately 64 thousand code units
+for the 8-bit and 16-bit libraries if PCRE2 is compiled with the default
+internal linkage size, which is 2 bytes for these libraries. If you want to
+process regular expressions that are truly enormous, you can compile PCRE2 with
+an internal linkage size of 3 or 4 (when building the 16-bit library, 3 is
+rounded up to 4). See the README file in the source distribution and the
+pcre2build
+documentation for details. In these cases the limit is substantially larger.
+However, the speed of execution is slower. In the 32-bit library, the internal
+linkage size is always 4.
+

+

+The maximum length of a source pattern string is essentially unlimited; it is
+the largest number a PCRE2_SIZE variable can hold. However, the program that
+calls pcre2_compile() can specify a smaller limit.
+

+

+The maximum length (in code units) of a subject string is one less than the
+largest number a PCRE2_SIZE variable can hold. PCRE2_SIZE is an unsigned
+integer type, usually defined as size_t. Its maximum value (that is
+~(PCRE2_SIZE)0) is reserved as a special indicator for zero-terminated strings
+and unset offsets.
+

+

+All values in repeating quantifiers must be less than 65536.
+

+

+There are two different limits that apply to branches of lookbehind assertions.
+If every branch in such an assertion matches a fixed number of characters,
+the maximum length of any branch is 65535 characters. If any branch matches a
+variable number of characters, then the maximum matching length for every
+branch is limited. The default limit is set at compile time, defaulting to 255,
+but can be changed by the calling program.
+

+

+There is no limit to the number of parenthesized groups, but there can be no
+more than 65535 capture groups, and there is a limit to the depth of nesting of
+parenthesized subpatterns of all kinds. This is imposed in order to limit the
+amount of system stack used at compile time. The default limit can be specified
+when PCRE2 is built; if not, the default is set to 250. An application can
+change this limit by calling pcre2_set_parens_nest_limit() to set the limit in
+a compile context.
+

+

+The maximum length of name for a named capture group is 32 code units, and the
+maximum number of such groups is 10000.
+

+

+The maximum length of a name in a (*MARK), (*PRUNE), (*SKIP), or (*THEN) verb
+is 255 code units for the 8-bit library and 65535 code units for the 16-bit and
+32-bit libraries.
+

+

+The maximum length of a string argument to a callout is the largest number a
+32-bit unsigned integer can hold.
+

+

+The maximum amount of heap memory used for matching is controlled by the heap
+limit, which can be set in a pattern or in a match context. The default is a
+very large number, effectively unlimited.

PCRE2 MATCHING ALGORITHMS

+

+This document describes the two different algorithms that are available in
+PCRE2 for matching a compiled regular expression against a given subject
+string. The "standard" algorithm is the one provided by the pcre2_match()
+function. This works in the same as Perl's matching function, and provide a
+Perl-compatible matching operation. The just-in-time (JIT) optimization that is
+described in the
+pcre2jit
+documentation is compatible with this function.
+

+

+An alternative algorithm is provided by the pcre2_dfa_match() function;
+it operates in a different way, and is not Perl-compatible. This alternative
+has advantages and disadvantages compared with the standard algorithm, and
+these are described below.
+

+

+When there is only one possible way in which a given subject string can match a
+pattern, the two algorithms give the same answer. A difference arises, however,
+when there are multiple possibilities. For example, if the pattern
+
+  ^<.*>
+

+is matched against the string
+
+  <something> <something else> <something further>
+

+there are three possible answers. The standard algorithm finds only one of
+them, whereas the alternative algorithm finds all three.
+

+
REGULAR EXPRESSIONS AS TREES

+

+The set of strings that are matched by a regular expression can be represented
+as a tree structure. An unlimited repetition in the pattern makes the tree of
+infinite size, but it is still a tree. Matching the pattern to a given subject
+string (from a given starting point) can be thought of as a search of the tree.
+There are two ways to search a tree: depth-first and breadth-first, and these
+correspond to the two matching algorithms provided by PCRE2.
+

+
THE STANDARD MATCHING ALGORITHM

+

+In the terminology of Jeffrey Friedl's book "Mastering Regular Expressions",
+the standard algorithm is an "NFA algorithm". It conducts a depth-first search
+of the pattern tree. That is, it proceeds along a single path through the tree,
+checking that the subject matches what is required. When there is a mismatch,
+the algorithm tries any alternatives at the current point, and if they all
+fail, it backs up to the previous branch point in the tree, and tries the next
+alternative branch at that level. This often involves backing up (moving to the
+left) in the subject string as well. The order in which repetition branches are
+tried is controlled by the greedy or ungreedy nature of the quantifier.
+

+

+If a leaf node is reached, a matching string has been found, and at that point
+the algorithm stops. Thus, if there is more than one possible match, this
+algorithm returns the first one that it finds. Whether this is the shortest,
+the longest, or some intermediate length depends on the way the alternations
+and the greedy or ungreedy repetition quantifiers are specified in the
+pattern.
+

+

+Because it ends up with a single path through the tree, it is relatively
+straightforward for this algorithm to keep track of the substrings that are
+matched by portions of the pattern in parentheses. This provides support for
+capturing parentheses and backreferences.
+

+
THE ALTERNATIVE MATCHING ALGORITHM

+

+This algorithm conducts a breadth-first search of the tree. Starting from the
+first matching point in the subject, it scans the subject string from left to
+right, once, character by character, and as it does this, it remembers all the
+paths through the tree that represent valid matches. In Friedl's terminology,
+this is a kind of "DFA algorithm", though it is not implemented as a
+traditional finite state machine (it keeps multiple states active
+simultaneously).
+

+

+Although the general principle of this matching algorithm is that it scans the
+subject string only once, without backtracking, there is one exception: when a
+lookaround assertion is encountered, the characters following or preceding the
+current point have to be independently inspected.
+

+

+The scan continues until either the end of the subject is reached, or there are
+no more unterminated paths. At this point, terminated paths represent the
+different matching possibilities (if there are none, the match has failed).
+Thus, if there is more than one possible match, this algorithm finds all of
+them, and in particular, it finds the longest. The matches are returned in
+the output vector in decreasing order of length. There is an option to stop the
+algorithm after the first match (which is necessarily the shortest) is found.
+

+

+Note that the size of vector needed to contain all the results depends on the
+number of simultaneous matches, not on the number of parentheses in the
+pattern. Using pcre2_match_data_create_from_pattern() to create the match
+data block is therefore not advisable when doing DFA matching.
+

+

+Note also that all the matches that are found start at the same point in the
+subject. If the pattern
+
+  cat(er(pillar)?)?
+

+is matched against the string "the caterpillar catchment", the result is the
+three strings "caterpillar", "cater", and "cat" that start at the fifth
+character of the subject. The algorithm does not automatically move on to find
+matches that start at later positions.
+

+

+PCRE2's "auto-possessification" optimization usually applies to character
+repeats at the end of a pattern (as well as internally). For example, the
+pattern "a\d+" is compiled as if it were "a\d++" because there is no point
+even considering the possibility of backtracking into the repeated digits. For
+DFA matching, this means that only one possible match is found. If you really
+do want multiple matches in such cases, either use an ungreedy repeat
+("a\d+?") or set the PCRE2_NO_AUTO_POSSESS option when compiling.
+

+

+There are a number of features of PCRE2 regular expressions that are not
+supported or behave differently in the alternative matching function. Those
+that are not supported cause an error if encountered.
+

+

+1. Because the algorithm finds all possible matches, the greedy or ungreedy
+nature of repetition quantifiers is not relevant (though it may affect
+auto-possessification, as just described). During matching, greedy and ungreedy
+quantifiers are treated in exactly the same way. However, possessive
+quantifiers can make a difference when what follows could also match what is
+quantified, for example in a pattern like this:
+
+  ^a++\w!
+

+This pattern matches "aaab!" but not "aaa!", which would be matched by a
+non-possessive quantifier. Similarly, if an atomic group is present, it is
+matched as if it were a standalone pattern at the current point, and the
+longest match is then "locked in" for the rest of the overall pattern.
+

+

+2. When dealing with multiple paths through the tree simultaneously, it is not
+straightforward to keep track of captured substrings for the different matching
+possibilities, and PCRE2's implementation of this algorithm does not attempt to
+do this. This means that no captured substrings are available.
+

+

+3. Because no substrings are captured, backreferences within the pattern are
+not supported.
+

+

+4. For the same reason, conditional expressions that use a backreference as the
+condition or test for a specific group recursion are not supported.
+

+

+5. Again for the same reason, script runs are not supported.
+

+

+6. Because many paths through the tree may be active, the \K escape sequence,
+which resets the start of the match when encountered (but may be on some paths
+and not on others), is not supported.
+

+

+7. Callouts are supported, but the value of the capture_top field is
+always 1, and the value of the capture_last field is always 0.
+

+

+8. The \C escape sequence, which (in the standard algorithm) always matches a
+single code unit, even in a UTF mode, is not supported in these modes, because
+the alternative algorithm moves through the subject string one character (not
+code unit) at a time, for all active paths through the tree.
+

+

+9. Except for (*FAIL), the backtracking control verbs such as (*PRUNE) are not
+supported. (*FAIL) is supported, and behaves like a failing negative assertion.
+

+

+10. The PCRE2_MATCH_INVALID_UTF option for pcre2_compile() is not
+supported by pcre2_dfa_match().
+

+
ADVANTAGES OF THE ALTERNATIVE ALGORITHM

+

+The main advantage of the alternative algorithm is that all possible matches
+(at a single point in the subject) are automatically found, and in particular,
+the longest match is found. To find more than one match at the same point using
+the standard algorithm, you have to do kludgy things with callouts.
+

+

+Partial matching is possible with this algorithm, though it has some
+limitations. The
+pcre2partial
+documentation gives details of partial matching and discusses multi-segment
+matching.
+

+
DISADVANTAGES OF THE ALTERNATIVE ALGORITHM

+

+The alternative algorithm suffers from a number of disadvantages:
+

+

+1. It is substantially slower than the standard algorithm. This is partly
+because it has to search for all possible matches, but is also because it is
+less susceptible to optimization.
+

+

+2. Capturing parentheses, backreferences, script runs, and matching within
+invalid UTF string are not supported.
+

+

+3. Although atomic groups are supported, their use does not provide the
+performance advantage that it does for the standard algorithm.
+

+

+4. JIT optimization is not supported.

+
PARTIAL MATCHING IN PCRE2

+

+In normal use of PCRE2, if there is a match up to the end of a subject string,
+but more characters are needed to match the entire pattern, PCRE2_ERROR_NOMATCH
+is returned, just like any other failing match. There are circumstances where
+it might be helpful to distinguish this "partial match" case.
+

+

+One example is an application where the subject string is very long, and not
+all available at once. The requirement here is to be able to do the matching
+segment by segment, but special action is needed when a matched substring spans
+the boundary between two segments.
+

+

+Another example is checking a user input string as it is typed, to ensure that
+it conforms to a required format. Invalid characters can be immediately
+diagnosed and rejected, giving instant feedback.
+

+

+Partial matching is a PCRE2-specific feature; it is not Perl-compatible. It is
+requested by setting one of the PCRE2_PARTIAL_HARD or PCRE2_PARTIAL_SOFT
+options when calling a matching function. The difference between the two
+options is whether or not a partial match is preferred to an alternative
+complete match, though the details differ between the two types of matching
+function. If both options are set, PCRE2_PARTIAL_HARD takes precedence.
+

+

+If you want to use partial matching with just-in-time optimized code, as well
+as setting a partial match option for the matching function, you must also call
+pcre2_jit_compile() with one or both of these options:
+
+  PCRE2_JIT_PARTIAL_HARD
+  PCRE2_JIT_PARTIAL_SOFT
+

+PCRE2_JIT_COMPLETE should also be set if you are going to run non-partial
+matches on the same pattern. Separate code is compiled for each mode. If the
+appropriate JIT mode has not been compiled, interpretive matching code is used.
+

+

+Setting a partial matching option disables two of PCRE2's standard
+optimization hints. PCRE2 remembers the last literal code unit in a pattern,
+and abandons matching immediately if it is not present in the subject string.
+This optimization cannot be used for a subject string that might match only
+partially. PCRE2 also remembers a minimum length of a matching string, and does
+not bother to run the matching function on shorter strings. This optimization
+is also disabled for partial matching.
+

+
REQUIREMENTS FOR A PARTIAL MATCH

+

+A possible partial match occurs during matching when the end of the subject
+string is reached successfully, but either more characters are needed to
+complete the match, or the addition of more characters might change what is
+matched.
+

+

+Example 1: if the pattern is /abc/ and the subject is "ab", more characters are
+definitely needed to complete a match. In this case both hard and soft matching
+options yield a partial match.
+

+

+Example 2: if the pattern is /ab+/ and the subject is "ab", a complete match
+can be found, but the addition of more characters might change what is
+matched. In this case, only PCRE2_PARTIAL_HARD returns a partial match;
+PCRE2_PARTIAL_SOFT returns the complete match.
+

+

+On reaching the end of the subject, when PCRE2_PARTIAL_HARD is set, if the next
+pattern item is \z, \Z, \b, \B, or $ there is always a partial match.
+Otherwise, for both options, the next pattern item must be one that inspects a
+character, and at least one of the following must be true:
+

+

+(1) At least one character has already been inspected. An inspected character
+need not form part of the final matched string; lookbehind assertions and the
+\K escape sequence provide ways of inspecting characters before the start of a
+matched string.
+

+

+(2) The pattern contains one or more lookbehind assertions. This condition
+exists in case there is a lookbehind that inspects characters before the start
+of the match.
+

+

+(3) There is a special case when the whole pattern can match an empty string.
+When the starting point is at the end of the subject, the empty string match is
+a possibility, and if PCRE2_PARTIAL_SOFT is set and neither of the above
+conditions is true, it is returned. However, because adding more characters
+might result in a non-empty match, PCRE2_PARTIAL_HARD returns a partial match,
+which in this case means "there is going to be a match at this point, but until
+some more characters are added, we do not know if it will be an empty string or
+something longer".
+

+
PARTIAL MATCHING USING pcre2_match()

+

+When a partial matching option is set, the result of calling
+pcre2_match() can be one of the following:
+

+

+A successful match
+A complete match has been found, starting and ending within this subject.
+

+

+PCRE2_ERROR_NOMATCH
+No match can start anywhere in this subject.
+

+

+PCRE2_ERROR_PARTIAL
+Adding more characters may result in a complete match that uses one or more
+characters from the end of this subject.
+

+

+When a partial match is returned, the first two elements in the ovector point
+to the portion of the subject that was matched, but the values in the rest of
+the ovector are undefined. The appearance of \K in the pattern has no effect
+for a partial match. Consider this pattern:
+
+  /abc\K123/
+

+If it is matched against "456abc123xyz" the result is a complete match, and the
+ovector defines the matched string as "123", because \K resets the "start of
+match" point. However, if a partial match is requested and the subject string
+is "456abc12", a partial match is found for the string "abc12", because all
+these characters are needed for a subsequent re-match with additional
+characters.
+

+

+If there is more than one partial match, the first one that was found provides
+the data that is returned. Consider this pattern:
+
+  /123\w+X|dogY/
+

+If this is matched against the subject string "abc123dog", both alternatives
+fail to match, but the end of the subject is reached during matching, so
+PCRE2_ERROR_PARTIAL is returned. The offsets are set to 3 and 9, identifying
+"123dog" as the first partial match. (In this example, there are two partial
+matches, because "dog" on its own partially matches the second alternative.)
+

+

+How a partial match is processed by pcre2_match()
+

+

+What happens when a partial match is identified depends on which of the two
+partial matching options is set.
+

+

+If PCRE2_PARTIAL_HARD is set, PCRE2_ERROR_PARTIAL is returned as soon as a
+partial match is found, without continuing to search for possible complete
+matches. This option is "hard" because it prefers an earlier partial match over
+a later complete match. For this reason, the assumption is made that the end of
+the supplied subject string is not the true end of the available data, which is
+why \z, \Z, \b, \B, and $ always give a partial match.
+

+

+If PCRE2_PARTIAL_SOFT is set, the partial match is remembered, but matching
+continues as normal, and other alternatives in the pattern are tried. If no
+complete match can be found, PCRE2_ERROR_PARTIAL is returned instead of
+PCRE2_ERROR_NOMATCH. This option is "soft" because it prefers a complete match
+over a partial match. All the various matching items in a pattern behave as if
+the subject string is potentially complete; \z, \Z, and $ match at the end of
+the subject, as normal, and for \b and \B the end of the subject is treated
+as a non-alphanumeric.
+

+

+The difference between the two partial matching options can be illustrated by a
+pattern such as:
+
+  /dog(sbody)?/
+

+This matches either "dog" or "dogsbody", greedily (that is, it prefers the
+longer string if possible). If it is matched against the string "dog" with
+PCRE2_PARTIAL_SOFT, it yields a complete match for "dog". However, if
+PCRE2_PARTIAL_HARD is set, the result is PCRE2_ERROR_PARTIAL. On the other
+hand, if the pattern is made ungreedy the result is different:
+
+  /dog(sbody)??/
+

+In this case the result is always a complete match because that is found first,
+and matching never continues after finding a complete match. It might be easier
+to follow this explanation by thinking of the two patterns like this:
+
+  /dog(sbody)?/    is the same as  /dogsbody|dog/
+  /dog(sbody)??/   is the same as  /dog|dogsbody/
+

+The second pattern will never match "dogsbody", because it will always find the
+shorter match first.
+

+

+Example of partial matching using pcre2test
+

+

+The pcre2test data modifiers partial_hard (or ph) and
+partial_soft (or ps) set PCRE2_PARTIAL_HARD and PCRE2_PARTIAL_SOFT,
+respectively, when calling pcre2_match(). Here is a run of
+pcre2test using a pattern that matches the whole subject in the form of a
+date:
+
+    re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+  data> 25dec3\=ph
+  Partial match: 23dec3
+  data> 3ju\=ph
+  Partial match: 3ju
+  data> 3juj\=ph
+  No match
+

+This example gives the same results for both hard and soft partial matching
+options. Here is an example where there is a difference:
+
+    re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+  data> 25jun04\=ps
+   0: 25jun04
+   1: jun
+  data> 25jun04\=ph
+  Partial match: 25jun04
+

+With PCRE2_PARTIAL_SOFT, the subject is matched completely. For
+PCRE2_PARTIAL_HARD, however, the subject is assumed not to be complete, so
+there is only a partial match.
+

+
MULTI-SEGMENT MATCHING WITH pcre2_match()

+

+PCRE was not originally designed with multi-segment matching in mind. However,
+over time, features (including partial matching) that make multi-segment
+matching possible have been added. A very long string can be searched segment
+by segment by calling pcre2_match() repeatedly, with the aim of achieving
+the same results that would happen if the entire string was available for
+searching all the time. Normally, the strings that are being sought are much
+shorter than each individual segment, and are in the middle of very long
+strings, so the pattern is normally not anchored.
+

+

+Special logic must be implemented to handle a matched substring that spans a
+segment boundary. PCRE2_PARTIAL_HARD should be used, because it returns a
+partial match at the end of a segment whenever there is the possibility of
+changing the match by adding more characters. The PCRE2_NOTBOL option should
+also be set for all but the first segment.
+

+

+When a partial match occurs, the next segment must be added to the current
+subject and the match re-run, using the startoffset argument of
+pcre2_match() to begin at the point where the partial match started.
+For example:
+
+    re> /\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d/
+  data> ...the date is 23ja\=ph
+  Partial match: 23ja
+  data> ...the date is 23jan19 and on that day...\=offset=15
+   0: 23jan19
+   1: jan
+

+Note the use of the offset modifier to start the new match where the
+partial match was found. In this example, the next segment was added to the one
+in which the partial match was found. This is the most straightforward
+approach, typically using a memory buffer that is twice the size of each
+segment. After a partial match, the first half of the buffer is discarded, the
+second half is moved to the start of the buffer, and a new segment is added
+before repeating the match as in the example above. After a no match, the
+entire buffer can be discarded.
+

+

+If there are memory constraints, you may want to discard text that precedes a
+partial match before adding the next segment. Unfortunately, this is not at
+present straightforward. In cases such as the above, where the pattern does not
+contain any lookbehinds, it is sufficient to retain only the partially matched
+substring. However, if the pattern contains a lookbehind assertion, characters
+that precede the start of the partial match may have been inspected during the
+matching process. When pcre2test displays a partial match, it indicates
+these characters with '<' if the allusedtext modifier is set:
+
+    re> "(?<=123)abc"
+  data> xx123ab\=ph,allusedtext
+  Partial match: 123ab
+                 <<<
+

+However, the allusedtext modifier is not available for JIT matching,
+because JIT matching does not record the first (or last) consulted characters.
+For this reason, this information is not available via the API. It is therefore
+not possible in general to obtain the exact number of characters that must be
+retained in order to get the right match result. If you cannot retain the
+entire segment, you must find some heuristic way of choosing.
+

+

+If you know the approximate length of the matching substrings, you can use that
+to decide how much text to retain. The only lookbehind information that is
+currently available via the API is the length of the longest individual
+lookbehind in a pattern, but this can be misleading if there are nested
+lookbehinds. The value returned by calling pcre2_pattern_info() with the
+PCRE2_INFO_MAXLOOKBEHIND option is the maximum number of characters (not code
+units) that any individual lookbehind moves back when it is processed. A
+pattern such as "(?<=(?<!b)a)" has a maximum lookbehind value of one, but
+inspects two characters before its starting point.
+

+

+In a non-UTF or a 32-bit case, moving back is just a subtraction, but in
+UTF-8 or UTF-16 you have to count characters while moving back through the code
+units.
+

+
PARTIAL MATCHING USING pcre2_dfa_match()

+

+The DFA function moves along the subject string character by character, without
+backtracking, searching for all possible matches simultaneously. If the end of
+the subject is reached before the end of the pattern, there is the possibility
+of a partial match.
+

+

+When PCRE2_PARTIAL_SOFT is set, PCRE2_ERROR_PARTIAL is returned only if there
+have been no complete matches. Otherwise, the complete matches are returned.
+If PCRE2_PARTIAL_HARD is set, a partial match takes precedence over any
+complete matches. The portion of the string that was matched when the longest
+partial match was found is set as the first matching string.
+

+

+Because the DFA function always searches for all possible matches, and there is
+no difference between greedy and ungreedy repetition, its behaviour is
+different from the pcre2_match(). Consider the string "dog" matched
+against this ungreedy pattern:
+
+  /dog(sbody)??/
+

+Whereas the standard function stops as soon as it finds the complete match for
+"dog", the DFA function also finds the partial match for "dogsbody", and so
+returns that when PCRE2_PARTIAL_HARD is set.
+

+
MULTI-SEGMENT MATCHING WITH pcre2_dfa_match()

+

+When a partial match has been found using the DFA matching function, it is
+possible to continue the match by providing additional subject data and calling
+the function again with the same compiled regular expression, this time setting
+the PCRE2_DFA_RESTART option. You must pass the same working space as before,
+because this is where details of the previous partial match are stored. You can
+set the PCRE2_PARTIAL_SOFT or PCRE2_PARTIAL_HARD options with PCRE2_DFA_RESTART
+to continue partial matching over multiple segments. Here is an example using
+pcre2test:
+
+    re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+  data> 23ja\=dfa,ps
+  Partial match: 23ja
+  data> n05\=dfa,dfa_restart
+   0: n05
+

+The first call has "23ja" as the subject, and requests partial matching; the
+second call has "n05" as the subject for the continued (restarted) match.
+Notice that when the match is complete, only the last part is shown; PCRE2 does
+not retain the previously partially-matched string. It is up to the calling
+program to do that if it needs to. This means that, for an unanchored pattern,
+if a continued match fails, it is not possible to try again at a new starting
+point. All this facility is capable of doing is continuing with the previous
+match attempt. For example, consider this pattern:
+
+  1234|3789
+

+If the first part of the subject is "ABC123", a partial match of the first
+alternative is found at offset 3. There is no partial match for the second
+alternative, because such a match does not start at the same point in the
+subject string. Attempting to continue with the string "7890" does not yield a
+match because only those alternatives that match at one point in the subject
+are remembered. Depending on the application, this may or may not be what you
+want.
+

+

+If you do want to allow for starting again at the next character, one way of
+doing it is to retain some or all of the segment and try a new complete match,
+as described for pcre2_match() above. Another possibility is to work with
+two buffers. If a partial match at offset n in the first buffer is
+followed by "no match" when PCRE2_DFA_RESTART is used on the second buffer, you
+can then try a new match starting at offset n+1 in the first buffer.

PCRE2 REGULAR EXPRESSION DETAILS

+

+The syntax and semantics of the regular expressions that are supported by PCRE2
+are described in detail below. There is a quick-reference syntax summary in the
+pcre2syntax
+page. PCRE2 tries to match Perl syntax and semantics as closely as it can.
+PCRE2 also supports some alternative regular expression syntax (which does not
+conflict with the Perl syntax) in order to provide some compatibility with
+regular expressions in Python, .NET, and Oniguruma.
+

+

+Perl's regular expressions are described in its own documentation, and regular
+expressions in general are covered in a number of books, some of which have
+copious examples. Jeffrey Friedl's "Mastering Regular Expressions", published
+by O'Reilly, covers regular expressions in great detail. This description of
+PCRE2's regular expressions is intended as reference material.
+

+

+This document discusses the regular expression patterns that are supported by
+PCRE2 when its main matching function, pcre2_match(), is used. PCRE2 also
+has an alternative matching function, pcre2_dfa_match(), which matches
+using a different algorithm that is not Perl-compatible. Some of the features
+discussed below are not available when DFA matching is used. The advantages and
+disadvantages of the alternative function, and how it differs from the normal
+function, are discussed in the
+pcre2matching
+page.
+

+
SPECIAL START-OF-PATTERN ITEMS

+

+A number of options that can be passed to pcre2_compile() can also be set
+by special items at the start of a pattern. These are not Perl-compatible, but
+are provided to make these options accessible to pattern writers who are not
+able to change the program that processes the pattern. Any number of these
+items may appear, but they must all be together right at the start of the
+pattern string, and the letters must be in upper case.
+

+

+UTF support
+

+

+In the 8-bit and 16-bit PCRE2 libraries, characters may be coded either as
+single code units, or as multiple UTF-8 or UTF-16 code units. UTF-32 can be
+specified for the 32-bit library, in which case it constrains the character
+values to valid Unicode code points. To process UTF strings, PCRE2 must be
+built to include Unicode support (which is the default). When using UTF strings
+you must either call the compiling function with one or both of the PCRE2_UTF
+or PCRE2_MATCH_INVALID_UTF options, or the pattern must start with the special
+sequence (*UTF), which is equivalent to setting the relevant PCRE2_UTF. How
+setting a UTF mode affects pattern matching is mentioned in several places
+below. There is also a summary of features in the
+pcre2unicode
+page.
+

+

+Some applications that allow their users to supply patterns may wish to
+restrict them to non-UTF data for security reasons. If the PCRE2_NEVER_UTF
+option is passed to pcre2_compile(), (*UTF) is not allowed, and its
+appearance in a pattern causes an error.
+

+

+Unicode property support
+

+

+Another special sequence that may appear at the start of a pattern is (*UCP).
+This has the same effect as setting the PCRE2_UCP option: it causes sequences
+such as \d and \w to use Unicode properties to determine character types,
+instead of recognizing only characters with codes less than 256 via a lookup
+table. If also causes upper/lower casing operations to use Unicode properties
+for characters with code points greater than 127, even when UTF is not set.
+These behaviours can be changed within the pattern; see the section entitled
+"Internal Option Setting"
+below.
+

+

+Some applications that allow their users to supply patterns may wish to
+restrict them for security reasons. If the PCRE2_NEVER_UCP option is passed to
+pcre2_compile(), (*UCP) is not allowed, and its appearance in a pattern
+causes an error.
+

+

+Locking out empty string matching
+

+

+Starting a pattern with (*NOTEMPTY) or (*NOTEMPTY_ATSTART) has the same effect
+as passing the PCRE2_NOTEMPTY or PCRE2_NOTEMPTY_ATSTART option to whichever
+matching function is subsequently called to match the pattern. These options
+lock out the matching of empty strings, either entirely, or only at the start
+of the subject.
+

+

+Disabling auto-possessification
+

+

+If a pattern starts with (*NO_AUTO_POSSESS), it has the same effect as setting
+the PCRE2_NO_AUTO_POSSESS option. This stops PCRE2 from making quantifiers
+possessive when what follows cannot match the repeated item. For example, by
+default a+b is treated as a++b. For more details, see the
+pcre2api
+documentation.
+

+

+Disabling start-up optimizations
+

+

+If a pattern starts with (*NO_START_OPT), it has the same effect as setting the
+PCRE2_NO_START_OPTIMIZE option. This disables several optimizations for quickly
+reaching "no match" results. For more details, see the
+pcre2api
+documentation.
+

+

+Disabling automatic anchoring
+

+

+If a pattern starts with (*NO_DOTSTAR_ANCHOR), it has the same effect as
+setting the PCRE2_NO_DOTSTAR_ANCHOR option. This disables optimizations that
+apply to patterns whose top-level branches all start with .* (match any number
+of arbitrary characters). For more details, see the
+pcre2api
+documentation.
+

+

+Disabling JIT compilation
+

+

+If a pattern that starts with (*NO_JIT) is successfully compiled, an attempt by
+the application to apply the JIT optimization by calling
+pcre2_jit_compile() is ignored.
+

+

+Setting match resource limits
+

+

+The pcre2_match() function contains a counter that is incremented every
+time it goes round its main loop. The caller of pcre2_match() can set a
+limit on this counter, which therefore limits the amount of computing resource
+used for a match. The maximum depth of nested backtracking can also be limited;
+this indirectly restricts the amount of heap memory that is used, but there is
+also an explicit memory limit that can be set.
+

+

+These facilities are provided to catch runaway matches that are provoked by
+patterns with huge matching trees. A common example is a pattern with nested
+unlimited repeats applied to a long string that does not match. When one of
+these limits is reached, pcre2_match() gives an error return. The limits
+can also be set by items at the start of the pattern of the form
+
+  (*LIMIT_HEAP=d)
+  (*LIMIT_MATCH=d)
+  (*LIMIT_DEPTH=d)
+

+where d is any number of decimal digits. However, the value of the setting must
+be less than the value set (or defaulted) by the caller of pcre2_match()
+for it to have any effect. In other words, the pattern writer can lower the
+limits set by the programmer, but not raise them. If there is more than one
+setting of one of these limits, the lower value is used. The heap limit is
+specified in kibibytes (units of 1024 bytes).
+

+

+Prior to release 10.30, LIMIT_DEPTH was called LIMIT_RECURSION. This name is
+still recognized for backwards compatibility.
+

+

+The heap limit applies only when the pcre2_match() or
+pcre2_dfa_match() interpreters are used for matching. It does not apply
+to JIT. The match limit is used (but in a different way) when JIT is being
+used, or when pcre2_dfa_match() is called, to limit computing resource
+usage by those matching functions. The depth limit is ignored by JIT but is
+relevant for DFA matching, which uses function recursion for recursions within
+the pattern and for lookaround assertions and atomic groups. In this case, the
+depth limit controls the depth of such recursion.
+

+

+Newline conventions
+

+

+PCRE2 supports six different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, any
+Unicode newline sequence, or the NUL character (binary zero). The
+pcre2api
+page has
+further discussion
+about newlines, and shows how to set the newline convention when calling
+pcre2_compile().
+

+

+It is also possible to specify a newline convention by starting a pattern
+string with one of the following sequences:
+
+  (*CR)        carriage return
+  (*LF)        linefeed
+  (*CRLF)      carriage return, followed by linefeed
+  (*ANYCRLF)   any of the three above
+  (*ANY)       all Unicode newline sequences
+  (*NUL)       the NUL character (binary zero)
+

+These override the default and the options given to the compiling function. For
+example, on a Unix system where LF is the default newline sequence, the pattern
+
+  (*CR)a.b
+

+changes the convention to CR. That pattern matches "a\nb" because LF is no
+longer a newline. If more than one of these settings is present, the last one
+is used.
+

+

+The newline convention affects where the circumflex and dollar assertions are
+true. It also affects the interpretation of the dot metacharacter when
+PCRE2_DOTALL is not set, and the behaviour of \N when not followed by an
+opening brace. However, it does not affect what the \R escape sequence
+matches. By default, this is any Unicode newline sequence, for Perl
+compatibility. However, this can be changed; see the next section and the
+description of \R in the section entitled
+"Newline sequences"
+below. A change of \R setting can be combined with a change of newline
+convention.
+

+

+Specifying what \R matches
+

+

+It is possible to restrict \R to match only CR, LF, or CRLF (instead of the
+complete set of Unicode line endings) by setting the option PCRE2_BSR_ANYCRLF
+at compile time. This effect can also be achieved by starting a pattern with
+(*BSR_ANYCRLF). For completeness, (*BSR_UNICODE) is also recognized,
+corresponding to PCRE2_BSR_UNICODE.
+

+
EBCDIC CHARACTER CODES

+

+PCRE2 can be compiled to run in an environment that uses EBCDIC as its
+character code instead of ASCII or Unicode (typically a mainframe system). In
+the sections below, character code values are ASCII or Unicode; in an EBCDIC
+environment these characters may have different code values, and there are no
+code points greater than 255.
+

+
CHARACTERS AND METACHARACTERS

+

+A regular expression is a pattern that is matched against a subject string from
+left to right. Most characters stand for themselves in a pattern, and match the
+corresponding characters in the subject. As a trivial example, the pattern
+
+  The quick brown fox
+

+matches a portion of a subject string that is identical to itself. When
+caseless matching is specified (the PCRE2_CASELESS option or (?i) within the
+pattern), letters are matched independently of case. Note that there are two
+ASCII characters, K and S, that, in addition to their lower case ASCII
+equivalents, are case-equivalent with Unicode U+212A (Kelvin sign) and U+017F
+(long S) respectively when either PCRE2_UTF or PCRE2_UCP is set, unless the
+PCRE2_EXTRA_CASELESS_RESTRICT option is in force (either passed to
+pcre2_compile() or set by (?r) within the pattern).
+

+

+The power of regular expressions comes from the ability to include wild cards,
+character classes, alternatives, and repetitions in the pattern. These are
+encoded in the pattern by the use of metacharacters, which do not stand
+for themselves but instead are interpreted in some special way.
+

+

+There are two different sets of metacharacters: those that are recognized
+anywhere in the pattern except within square brackets, and those that are
+recognized within square brackets. Outside square brackets, the metacharacters
+are as follows:
+
+  \      general escape character with several uses
+  ^      assert start of string (or line, in multiline mode)
+  $      assert end of string (or line, in multiline mode)
+  .      match any character except newline (by default)
+  [      start character class definition
+  |      start of alternative branch
+  (      start group or control verb
+  )      end group or control verb
+  *      0 or more quantifier
+  +      1 or more quantifier; also "possessive quantifier"
+  ?      0 or 1 quantifier; also quantifier minimizer
+  {      potential start of min/max quantifier
+

+Brace characters { and } are also used to enclose data for constructions such
+as \g{2} or \k{name}. In almost all uses of braces, space and/or horizontal
+tab characters that follow { or precede } are allowed and are ignored. In the
+case of quantifiers, they may also appear before or after the comma. The
+exception to this is \u{...} which is an ECMAScript compatibility feature
+that is recognized only when the PCRE2_EXTRA_ALT_BSUX option is set. ECMAScript
+does not ignore such white space; it causes the item to be interpreted as
+literal.
+

+

+Part of a pattern that is in square brackets is called a "character class". In
+a character class the only metacharacters are:
+
+  \      general escape character
+  ^      negate the class, but only if the first character
+  -      indicates character range
+  [      POSIX character class (if followed by POSIX syntax)
+  ]      terminates the character class
+

+If a pattern is compiled with the PCRE2_EXTENDED option, most white space in
+the pattern, other than in a character class, within a \Q...\E sequence, or
+between a # outside a character class and the next newline, inclusive, are
+ignored. An escaping backslash can be used to include a white space or a #
+character as part of the pattern. If the PCRE2_EXTENDED_MORE option is set, the
+same applies, but in addition unescaped space and horizontal tab characters are
+ignored inside a character class. Note: only these two characters are ignored,
+not the full set of pattern white space characters that are ignored outside a
+character class. Option settings can be changed within a pattern; see the
+section entitled
+"Internal Option Setting"
+below.
+

+

+The following sections describe the use of each of the metacharacters.
+

+
BACKSLASH

+

+The backslash character has several uses. Firstly, if it is followed by a
+character that is not a digit or a letter, it takes away any special meaning
+that character may have. This use of backslash as an escape character applies
+both inside and outside character classes.
+

+

+For example, if you want to match a * character, you must write \* in the
+pattern. This escaping action applies whether or not the following character
+would otherwise be interpreted as a metacharacter, so it is always safe to
+precede a non-alphanumeric with backslash to specify that it stands for itself.
+In particular, if you want to match a backslash, you write \\.
+

+

+Only ASCII digits and letters have any special meaning after a backslash. All
+other characters (in particular, those whose code points are greater than 127)
+are treated as literals.
+

+

+If you want to treat all characters in a sequence as literals, you can do so by
+putting them between \Q and \E. Note that this includes white space even when
+the PCRE2_EXTENDED option is set so that most other white space is ignored. The
+behaviour is different from Perl in that $ and @ are handled as literals in
+\Q...\E sequences in PCRE2, whereas in Perl, $ and @ cause variable
+interpolation. Also, Perl does "double-quotish backslash interpolation" on any
+backslashes between \Q and \E which, its documentation says, "may lead to
+confusing results". PCRE2 treats a backslash between \Q and \E just like any
+other character. Note the following examples:
+
+  Pattern            PCRE2 matches   Perl matches
+
+  \Qabc$xyz\E        abc$xyz        abc followed by the contents of $xyz
+  \Qabc\$xyz\E       abc\$xyz       abc\$xyz
+  \Qabc\E\$\Qxyz\E   abc$xyz        abc$xyz
+  \QA\B\E            A\B            A\B
+  \Q\\E              \              \\E
+

+The \Q...\E sequence is recognized both inside and outside character classes.
+An isolated \E that is not preceded by \Q is ignored. If \Q is not followed
+by \E later in the pattern, the literal interpretation continues to the end of
+the pattern (that is, \E is assumed at the end). If the isolated \Q is inside
+a character class, this causes an error, because the character class is then
+not terminated by a closing square bracket.
+

+

+Non-printing characters
+

+

+A second use of backslash provides a way of encoding non-printing characters
+in patterns in a visible manner. There is no restriction on the appearance of
+non-printing characters in a pattern, but when a pattern is being prepared by
+text editing, it is often easier to use one of the following escape sequences
+instead of the binary character it represents. In an ASCII or Unicode
+environment, these escapes are as follows:
+
+  \a          alarm, that is, the BEL character (hex 07)
+  \cx         "control-x", where x is a non-control ASCII character
+  \e          escape (hex 1B)
+  \f          form feed (hex 0C)
+  \n          linefeed (hex 0A)
+  \r          carriage return (hex 0D) (but see below)
+  \t          tab (hex 09)
+  \0dd        character with octal code 0dd
+  \ddd        character with octal code ddd, or backreference
+  \o{ddd..}   character with octal code ddd..
+  \xhh        character with hex code hh
+  \x{hhh..}   character with hex code hhh..
+  \N{U+hhh..} character with Unicode hex code point hhh..
+

+By default, after \x that is not followed by {, from zero to two hexadecimal
+digits are read (letters can be in upper or lower case). Any number of
+hexadecimal digits may appear between \x{ and }. If a character other than a
+hexadecimal digit appears between \x{ and }, or if there is no terminating },
+an error occurs.
+

+

+Characters whose code points are less than 256 can be defined by either of the
+two syntaxes for \x or by an octal sequence. There is no difference in the way
+they are handled. For example, \xdc is exactly the same as \x{dc} or \334.
+However, using the braced versions does make such sequences easier to read.
+

+

+Support is available for some ECMAScript (aka JavaScript) escape sequences via
+two compile-time options. If PCRE2_ALT_BSUX is set, the sequence \x followed
+by { is not recognized. Only if \x is followed by two hexadecimal digits is it
+recognized as a character escape. Otherwise it is interpreted as a literal "x"
+character. In this mode, support for code points greater than 256 is provided
+by \u, which must be followed by four hexadecimal digits; otherwise it is
+interpreted as a literal "u" character.
+

+

+PCRE2_EXTRA_ALT_BSUX has the same effect as PCRE2_ALT_BSUX and, in addition,
+\u{hhh..} is recognized as the character specified by hexadecimal code point.
+There may be any number of hexadecimal digits, but unlike other places that
+also use curly brackets, spaces are not allowed and would result in the string
+being interpreted as a literal. This syntax is from ECMAScript 6.
+

+

+The \N{U+hhh..} escape sequence is recognized only when PCRE2 is operating in
+UTF mode. Perl also uses \N{name} to specify characters by Unicode name; PCRE2
+does not support this. Note that when \N is not followed by an opening brace
+(curly bracket) it has an entirely different meaning, matching any character
+that is not a newline.
+

+

+There are some legacy applications where the escape sequence \r is expected to
+match a newline. If the PCRE2_EXTRA_ESCAPED_CR_IS_LF option is set, \r in a
+pattern is converted to \n so that it matches a LF (linefeed) instead of a CR
+(carriage return) character.
+

+

+An error occurs if \c is not followed by a character whose ASCII code point
+is in the range 32 to 126. The precise effect of \cx is as follows: if x is a
+lower case letter, it is converted to upper case. Then bit 6 of the character
+(hex 40) is inverted. Thus \cA to \cZ become hex 01 to hex 1A (A is 41, Z is
+5A), but \c{ becomes hex 3B ({ is 7B), and \c; becomes hex 7B (; is 3B). If
+the code unit following \c has a code point less than 32 or greater than 126,
+a compile-time error occurs.
+

+

+When PCRE2 is compiled in EBCDIC mode, \N{U+hhh..} is not supported. \a, \e,
+\f, \n, \r, and \t generate the appropriate EBCDIC code values. The \c
+escape is processed as specified for Perl in the perlebcdic document. The
+only characters that are allowed after \c are A-Z, a-z, or one of @, [, \, ],
+^, _, or ?. Any other character provokes a compile-time error. The sequence
+\c@ encodes character code 0; after \c the letters (in either case) encode
+characters 1-26 (hex 01 to hex 1A); [, \, ], ^, and _ encode characters 27-31
+(hex 1B to hex 1F), and \c? becomes either 255 (hex FF) or 95 (hex 5F).
+

+

+Thus, apart from \c?, these escapes generate the same character code values as
+they do in an ASCII environment, though the meanings of the values mostly
+differ. For example, \cG always generates code value 7, which is BEL in ASCII
+but DEL in EBCDIC.
+

+

+The sequence \c? generates DEL (127, hex 7F) in an ASCII environment, but
+because 127 is not a control character in EBCDIC, Perl makes it generate the
+APC character. Unfortunately, there are several variants of EBCDIC. In most of
+them the APC character has the value 255 (hex FF), but in the one Perl calls
+POSIX-BC its value is 95 (hex 5F). If certain other characters have POSIX-BC
+values, PCRE2 makes \c? generate 95; otherwise it generates 255.
+

+

+After \0 up to two further octal digits are read. If there are fewer than two
+digits, just those that are present are used. Thus the sequence \0\x\015
+specifies two binary zeros followed by a CR character (code value 13). Make
+sure you supply two digits after the initial zero if the pattern character that
+follows is itself an octal digit.
+

+

+The escape \o must be followed by a sequence of octal digits, enclosed in
+braces. An error occurs if this is not the case. This escape is a recent
+addition to Perl; it provides way of specifying character code points as octal
+numbers greater than 0777, and it also allows octal numbers and backreferences
+to be unambiguously specified.
+

+

+For greater clarity and unambiguity, it is best to avoid following \ by a
+digit greater than zero. Instead, use \o{...} or \x{...} to specify numerical
+character code points, and \g{...} to specify backreferences. The following
+paragraphs describe the old, ambiguous syntax.
+

+

+The handling of a backslash followed by a digit other than 0 is complicated,
+and Perl has changed over time, causing PCRE2 also to change.
+

+

+Outside a character class, PCRE2 reads the digit and any following digits as a
+decimal number. If the number is less than 10, begins with the digit 8 or 9, or
+if there are at least that many previous capture groups in the expression, the
+entire sequence is taken as a backreference. A description of how this
+works is given
+later,
+following the discussion of
+parenthesized groups.
+Otherwise, up to three octal digits are read to form a character code.
+

+

+Inside a character class, PCRE2 handles \8 and \9 as the literal characters
+"8" and "9", and otherwise reads up to three octal digits following the
+backslash, using them to generate a data character. Any subsequent digits stand
+for themselves. For example, outside a character class:
+
+  \040   is another way of writing an ASCII space
+  \40    is the same, provided there are fewer than 40 previous capture groups
+  \7     is always a backreference
+  \11    might be a backreference, or another way of writing a tab
+  \011   is always a tab
+  \0113  is a tab followed by the character "3"
+  \113   might be a backreference, otherwise the character with octal code 113
+  \377   might be a backreference, otherwise the value 255 (decimal)
+  \81    is always a backreference
+

+Note that octal values of 100 or greater that are specified using this syntax
+must not be introduced by a leading zero, because no more than three octal
+digits are ever read.
+

+

+Constraints on character values
+

+

+Characters that are specified using octal or hexadecimal numbers are
+limited to certain values, as follows:
+
+  8-bit non-UTF mode    no greater than 0xff
+  16-bit non-UTF mode   no greater than 0xffff
+  32-bit non-UTF mode   no greater than 0xffffffff
+  All UTF modes         no greater than 0x10ffff and a valid code point
+

+Invalid Unicode code points are all those in the range 0xd800 to 0xdfff (the
+so-called "surrogate" code points). The check for these can be disabled by the
+caller of pcre2_compile() by setting the option
+PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES. However, this is possible only in UTF-8
+and UTF-32 modes, because these values are not representable in UTF-16.
+

+

+Escape sequences in character classes
+

+

+All the sequences that define a single character value can be used both inside
+and outside character classes. In addition, inside a character class, \b is
+interpreted as the backspace character (hex 08).
+

+

+When not followed by an opening brace, \N is not allowed in a character class.
+\B, \R, and \X are not special inside a character class. Like other
+unrecognized alphabetic escape sequences, they cause an error. Outside a
+character class, these sequences have different meanings.
+

+

+Unsupported escape sequences
+

+

+In Perl, the sequences \F, \l, \L, \u, and \U are recognized by its string
+handler and used to modify the case of following characters. By default, PCRE2
+does not support these escape sequences in patterns. However, if either of the
+PCRE2_ALT_BSUX or PCRE2_EXTRA_ALT_BSUX options is set, \U matches a "U"
+character, and \u can be used to define a character by code point, as
+described above.
+

+

+Absolute and relative backreferences
+

+

+The sequence \g followed by a signed or unsigned number, optionally enclosed
+in braces, is an absolute or relative backreference. A named backreference
+can be coded as \g{name}. Backreferences are discussed
+later,
+following the discussion of
+parenthesized groups.
+

+

+Absolute and relative subroutine calls
+

+

+For compatibility with Oniguruma, the non-Perl syntax \g followed by a name or
+a number enclosed either in angle brackets or single quotes, is an alternative
+syntax for referencing a capture group as a subroutine. Details are discussed
+later.
+Note that \g{...} (Perl syntax) and \g<...> (Oniguruma syntax) are not
+synonymous. The former is a backreference; the latter is a
+subroutine
+call.
+

+

+Generic character types
+

+

+Another use of backslash is for specifying generic character types:
+
+  \d     any decimal digit
+  \D     any character that is not a decimal digit
+  \h     any horizontal white space character
+  \H     any character that is not a horizontal white space character
+  \N     any character that is not a newline
+  \s     any white space character
+  \S     any character that is not a white space character
+  \v     any vertical white space character
+  \V     any character that is not a vertical white space character
+  \w     any "word" character
+  \W     any "non-word" character
+

+The \N escape sequence has the same meaning as
+the "." metacharacter
+when PCRE2_DOTALL is not set, but setting PCRE2_DOTALL does not change the
+meaning of \N. Note that when \N is followed by an opening brace it has a
+different meaning. See the section entitled
+"Non-printing characters"
+above for details. Perl also uses \N{name} to specify characters by Unicode
+name; PCRE2 does not support this.
+

+

+Each pair of lower and upper case escape sequences partitions the complete set
+of characters into two disjoint sets. Any given character matches one, and only
+one, of each pair. The sequences can appear both inside and outside character
+classes. They each match one character of the appropriate type. If the current
+matching point is at the end of the subject string, all of them fail, because
+there is no character to match.
+

+

+The default \s characters are HT (9), LF (10), VT (11), FF (12), CR (13), and
+space (32), which are defined as white space in the "C" locale. This list may
+vary if locale-specific matching is taking place. For example, in some locales
+the "non-breaking space" character (\xA0) is recognized as white space, and in
+others the VT character is not.
+

+

+A "word" character is an underscore or any character that is a letter or digit.
+By default, the definition of letters and digits is controlled by PCRE2's
+low-valued character tables, and may vary if locale-specific matching is taking
+place (see
+"Locale support"
+in the
+pcre2api
+page). For example, in a French locale such as "fr_FR" in Unix-like systems,
+or "french" in Windows, some character codes greater than 127 are used for
+accented letters, and these are then matched by \w. The use of locales with
+Unicode is discouraged.
+

+

+By default, characters whose code points are greater than 127 never match \d,
+\s, or \w, and always match \D, \S, and \W, although this may be different
+for characters in the range 128-255 when locale-specific matching is happening.
+These escape sequences retain their original meanings from before Unicode
+support was available, mainly for efficiency reasons. If the PCRE2_UCP option
+is set, the behaviour is changed so that Unicode properties are used to
+determine character types, as follows:
+
+  \d  any character that matches \p{Nd} (decimal digit)
+  \s  any character that matches \p{Z} or \h or \v
+  \w  any character that matches \p{L}, \p{N}, \p{Mn}, or \p{Pc}
+

+The addition of \p{Mn} (non-spacing mark) and the replacement of an explicit
+test for underscore with a test for \p{Pc} (connector punctuation) happened in
+PCRE2 release 10.43. This brings PCRE2 into line with Perl.
+

+

+The upper case escapes match the inverse sets of characters. Note that \d
+matches only decimal digits, whereas \w matches any Unicode digit, as well as
+other character categories. Note also that PCRE2_UCP affects \b, and
+\B because they are defined in terms of \w and \W. Matching these sequences
+is noticeably slower when PCRE2_UCP is set.
+

+

+The effect of PCRE2_UCP on any one of these escape sequences can be negated by
+the options PCRE2_EXTRA_ASCII_BSD, PCRE2_EXTRA_ASCII_BSS, and
+PCRE2_EXTRA_ASCII_BSW, respectively. These options can be set and reset within
+a pattern by means of an internal option setting
+(see below).
+

+

+The sequences \h, \H, \v, and \V, in contrast to the other sequences, which
+match only ASCII characters by default, always match a specific list of code
+points, whether or not PCRE2_UCP is set. The horizontal space characters are:
+
+  U+0009     Horizontal tab (HT)
+  U+0020     Space
+  U+00A0     Non-break space
+  U+1680     Ogham space mark
+  U+180E     Mongolian vowel separator
+  U+2000     En quad
+  U+2001     Em quad
+  U+2002     En space
+  U+2003     Em space
+  U+2004     Three-per-em space
+  U+2005     Four-per-em space
+  U+2006     Six-per-em space
+  U+2007     Figure space
+  U+2008     Punctuation space
+  U+2009     Thin space
+  U+200A     Hair space
+  U+202F     Narrow no-break space
+  U+205F     Medium mathematical space
+  U+3000     Ideographic space
+

+The vertical space characters are:
+
+  U+000A     Linefeed (LF)
+  U+000B     Vertical tab (VT)
+  U+000C     Form feed (FF)
+  U+000D     Carriage return (CR)
+  U+0085     Next line (NEL)
+  U+2028     Line separator
+  U+2029     Paragraph separator
+

+In 8-bit, non-UTF-8 mode, only the characters with code points less than 256
+are relevant.
+

+

+Newline sequences
+

+

+Outside a character class, by default, the escape sequence \R matches any
+Unicode newline sequence. In 8-bit non-UTF-8 mode \R is equivalent to the
+following:
+
+  (?>\r\n|\n|\x0b|\f|\r|\x85)
+

+This is an example of an "atomic group", details of which are given
+below.
+This particular group matches either the two-character sequence CR followed by
+LF, or one of the single characters LF (linefeed, U+000A), VT (vertical tab,
+U+000B), FF (form feed, U+000C), CR (carriage return, U+000D), or NEL (next
+line, U+0085). Because this is an atomic group, the two-character sequence is
+treated as a single unit that cannot be split.
+

+

+In other modes, two additional characters whose code points are greater than 255
+are added: LS (line separator, U+2028) and PS (paragraph separator, U+2029).
+Unicode support is not needed for these characters to be recognized.
+

+

+It is possible to restrict \R to match only CR, LF, or CRLF (instead of the
+complete set of Unicode line endings) by setting the option PCRE2_BSR_ANYCRLF
+at compile time. (BSR is an abbreviation for "backslash R".) This can be made
+the default when PCRE2 is built; if this is the case, the other behaviour can
+be requested via the PCRE2_BSR_UNICODE option. It is also possible to specify
+these settings by starting a pattern string with one of the following
+sequences:
+
+  (*BSR_ANYCRLF)   CR, LF, or CRLF only
+  (*BSR_UNICODE)   any Unicode newline sequence
+

+These override the default and the options given to the compiling function.
+Note that these special settings, which are not Perl-compatible, are recognized
+only at the very start of a pattern, and that they must be in upper case. If
+more than one of them is present, the last one is used. They can be combined
+with a change of newline convention; for example, a pattern can start with:
+
+  (*ANY)(*BSR_ANYCRLF)
+

+They can also be combined with the (*UTF) or (*UCP) special sequences. Inside a
+character class, \R is treated as an unrecognized escape sequence, and causes
+an error.
+

+

+Unicode character properties
+

+

+When PCRE2 is built with Unicode support (the default), three additional escape
+sequences that match characters with specific properties are available. They
+can be used in any mode, though in 8-bit and 16-bit non-UTF modes these
+sequences are of course limited to testing characters whose code points are
+less than U+0100 and U+10000, respectively. In 32-bit non-UTF mode, code points
+greater than 0x10ffff (the Unicode limit) may be encountered. These are all
+treated as being in the Unknown script and with an unassigned type.
+

+

+Matching characters by Unicode property is not fast, because PCRE2 has to do a
+multistage table lookup in order to find a character's property. That is why
+the traditional escape sequences such as \d and \w do not use Unicode
+properties in PCRE2 by default, though you can make them do so by setting the
+PCRE2_UCP option or by starting the pattern with (*UCP).
+

+

+The extra escape sequences that provide property support are:
+
+  \p{xx}   a character with the xx property
+  \P{xx}   a character without the xx property
+  \X       a Unicode extended grapheme cluster
+

+The property names represented by xx above are not case-sensitive, and in
+accordance with Unicode's "loose matching" rules, spaces, hyphens, and
+underscores are ignored. There is support for Unicode script names, Unicode
+general category properties, "Any", which matches any character (including
+newline), Bidi_Class, a number of binary (yes/no) properties, and some special
+PCRE2 properties (described
+below).
+Certain other Perl properties such as "InMusicalSymbols" are not supported by
+PCRE2. Note that \P{Any} does not match any characters, so always causes a
+match failure.
+

+

+Script properties for \p and \P
+

+

+There are three different syntax forms for matching a script. Each Unicode
+character has a basic script and, optionally, a list of other scripts ("Script
+Extensions") with which it is commonly used. Using the Adlam script as an
+example, \p{sc:Adlam} matches characters whose basic script is Adlam, whereas
+\p{scx:Adlam} matches, in addition, characters that have Adlam in their
+extensions list. The full names "script" and "script extensions" for the
+property types are recognized, and a equals sign is an alternative to the
+colon. If a script name is given without a property type, for example,
+\p{Adlam}, it is treated as \p{scx:Adlam}. Perl changed to this
+interpretation at release 5.26 and PCRE2 changed at release 10.40.
+

+

+Unassigned characters (and in non-UTF 32-bit mode, characters with code points
+greater than 0x10FFFF) are assigned the "Unknown" script. Others that are not
+part of an identified script are lumped together as "Common". The current list
+of recognized script names and their 4-character abbreviations can be obtained
+by running this command:
+
+  pcre2test -LS
+
+

+

+

+The general category property for \p and \P
+

+

+Each character has exactly one Unicode general category property, specified by
+a two-letter abbreviation. For compatibility with Perl, negation can be
+specified by including a circumflex between the opening brace and the property
+name. For example, \p{^Lu} is the same as \P{Lu}.
+

+

+If only one letter is specified with \p or \P, it includes all the general
+category properties that start with that letter. In this case, in the absence
+of negation, the curly brackets in the escape sequence are optional; these two
+examples have the same effect:
+
+  \p{L}
+  \pL
+

+The following general category property codes are supported:
+
+  C     Other
+  Cc    Control
+  Cf    Format
+  Cn    Unassigned
+  Co    Private use
+  Cs    Surrogate
+
+  L     Letter
+  Ll    Lower case letter
+  Lm    Modifier letter
+  Lo    Other letter
+  Lt    Title case letter
+  Lu    Upper case letter
+
+  M     Mark
+  Mc    Spacing mark
+  Me    Enclosing mark
+  Mn    Non-spacing mark
+
+  N     Number
+  Nd    Decimal number
+  Nl    Letter number
+  No    Other number
+
+  P     Punctuation
+  Pc    Connector punctuation
+  Pd    Dash punctuation
+  Pe    Close punctuation
+  Pf    Final punctuation
+  Pi    Initial punctuation
+  Po    Other punctuation
+  Ps    Open punctuation
+
+  S     Symbol
+  Sc    Currency symbol
+  Sk    Modifier symbol
+  Sm    Mathematical symbol
+  So    Other symbol
+
+  Z     Separator
+  Zl    Line separator
+  Zp    Paragraph separator
+  Zs    Space separator
+

+The special property LC, which has the synonym L&, is also supported: it
+matches a character that has the Lu, Ll, or Lt property, in other words, a
+letter that is not classified as a modifier or "other".
+

+

+The Cs (Surrogate) property applies only to characters whose code points are in
+the range U+D800 to U+DFFF. These characters are no different to any other
+character when PCRE2 is not in UTF mode (using the 16-bit or 32-bit library).
+However, they are not valid in Unicode strings and so cannot be tested by PCRE2
+in UTF mode, unless UTF validity checking has been turned off (see the
+discussion of PCRE2_NO_UTF_CHECK in the
+pcre2api
+page).
+

+

+The long synonyms for property names that Perl supports (such as \p{Letter})
+are not supported by PCRE2, nor is it permitted to prefix any of these
+properties with "Is".
+

+

+No character that is in the Unicode table has the Cn (unassigned) property.
+Instead, this property is assumed for any code point that is not in the
+Unicode table.
+

+

+Specifying caseless matching does not affect these escape sequences. For
+example, \p{Lu} always matches only upper case letters. This is different from
+the behaviour of current versions of Perl.
+

+

+Binary (yes/no) properties for \p and \P
+

+

+Unicode defines a number of binary properties, that is, properties whose only
+values are true or false. You can obtain a list of those that are recognized by
+\p and \P, along with their abbreviations, by running this command:
+
+  pcre2test -LP
+
+

+

+

+The Bidi_Class property for \p and \P
+

+

+
+  \p{Bidi_Class:<class>}   matches a character with the given class
+  \p{BC:<class>}           matches a character with the given class
+

+The recognized classes are:
+
+  AL          Arabic letter
+  AN          Arabic number
+  B           paragraph separator
+  BN          boundary neutral
+  CS          common separator
+  EN          European number
+  ES          European separator
+  ET          European terminator
+  FSI         first strong isolate
+  L           left-to-right
+  LRE         left-to-right embedding
+  LRI         left-to-right isolate
+  LRO         left-to-right override
+  NSM         non-spacing mark
+  ON          other neutral
+  PDF         pop directional format
+  PDI         pop directional isolate
+  R           right-to-left
+  RLE         right-to-left embedding
+  RLI         right-to-left isolate
+  RLO         right-to-left override
+  S           segment separator
+  WS          which space
+

+An equals sign may be used instead of a colon. The class names are
+case-insensitive; only the short names listed above are recognized.
+

+

+Extended grapheme clusters
+

+

+The \X escape matches any number of Unicode characters that form an "extended
+grapheme cluster", and treats the sequence as an atomic group
+(see below).
+Unicode supports various kinds of composite character by giving each character
+a grapheme breaking property, and having rules that use these properties to
+define the boundaries of extended grapheme clusters. The rules are defined in
+Unicode Standard Annex 29, "Unicode Text Segmentation". Unicode 11.0.0
+abandoned the use of some previous properties that had been used for emojis.
+Instead it introduced various emoji-specific properties. PCRE2 uses only the
+Extended Pictographic property.
+

+

+\X always matches at least one character. Then it decides whether to add
+additional characters according to the following rules for ending a cluster:
+

+

+1. End at the end of the subject string.
+

+

+2. Do not end between CR and LF; otherwise end after any control character.
+

+

+3. Do not break Hangul (a Korean script) syllable sequences. Hangul characters
+are of five types: L, V, T, LV, and LVT. An L character may be followed by an
+L, V, LV, or LVT character; an LV or V character may be followed by a V or T
+character; an LVT or T character may be followed only by a T character.
+

+

+4. Do not end before extending characters or spacing marks or the zero-width
+joiner (ZWJ) character. Characters with the "mark" property always have the
+"extend" grapheme breaking property.
+

+

+5. Do not end after prepend characters.
+

+

+6. Do not end within emoji modifier sequences or emoji ZWJ (zero-width
+joiner) sequences. An emoji ZWJ sequence consists of a character with the
+Extended_Pictographic property, optionally followed by one or more characters
+with the Extend property, followed by the ZWJ character, followed by another
+Extended_Pictographic character.
+

+

+7. Do not break within emoji flag sequences. That is, do not break between
+regional indicator (RI) characters if there are an odd number of RI characters
+before the break point.
+

+

+8. Otherwise, end the cluster.
+

+

+PCRE2's additional properties
+

+

+As well as the standard Unicode properties described above, PCRE2 supports four
+more that make it possible to convert traditional escape sequences such as \w
+and \s to use Unicode properties. PCRE2 uses these non-standard, non-Perl
+properties internally when PCRE2_UCP is set. However, they may also be used
+explicitly. These properties are:
+
+  Xan   Any alphanumeric character
+  Xps   Any POSIX space character
+  Xsp   Any Perl space character
+  Xwd   Any Perl "word" character
+

+Xan matches characters that have either the L (letter) or the N (number)
+property. Xps matches the characters tab, linefeed, vertical tab, form feed, or
+carriage return, and any other character that has the Z (separator) property.
+Xsp is the same as Xps; in PCRE1 it used to exclude vertical tab, for Perl
+compatibility, but Perl changed. Xwd matches the same characters as Xan, plus
+those that match Mn (non-spacing mark) or Pc (connector punctuation, which
+includes underscore).
+

+

+There is another non-standard property, Xuc, which matches any character that
+can be represented by a Universal Character Name in C++ and other programming
+languages. These are the characters $, @, ` (grave accent), and all characters
+with Unicode code points greater than or equal to U+00A0, except for the
+surrogates U+D800 to U+DFFF. Note that most base (ASCII) characters are
+excluded. (Universal Character Names are of the form \uHHHH or \UHHHHHHHH
+where H is a hexadecimal digit. Note that the Xuc property does not match these
+sequences but the characters that they represent.)
+

+

+Resetting the match start
+

+

+In normal use, the escape sequence \K causes any previously matched characters
+not to be included in the final matched sequence that is returned. For example,
+the pattern:
+
+  foo\Kbar
+

+matches "foobar", but reports that it has matched "bar". \K does not interact
+with anchoring in any way. The pattern:
+
+  ^foo\Kbar
+

+matches only when the subject begins with "foobar" (in single line mode),
+though it again reports the matched string as "bar". This feature is similar to
+a lookbehind assertion
+(described below),
+but the part of the pattern that precedes \K is not constrained to match a
+limited number of characters, as is required for a lookbehind assertion. The
+use of \K does not interfere with the setting of
+captured substrings.
+For example, when the pattern
+
+  (foo)\Kbar
+

+matches "foobar", the first substring is still set to "foo".
+

+

+From version 5.32.0 Perl forbids the use of \K in lookaround assertions. From
+release 10.38 PCRE2 also forbids this by default. However, the
+PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK option can be used when calling
+pcre2_compile() to re-enable the previous behaviour. When this option is
+set, \K is acted upon when it occurs inside positive assertions, but is
+ignored in negative assertions. Note that when a pattern such as (?=ab\K)
+matches, the reported start of the match can be greater than the end of the
+match. Using \K in a lookbehind assertion at the start of a pattern can also
+lead to odd effects. For example, consider this pattern:
+
+  (?<=\Kfoo)bar
+

+If the subject is "foobar", a call to pcre2_match() with a starting
+offset of 3 succeeds and reports the matching string as "foobar", that is, the
+start of the reported match is earlier than where the match started.
+

+

+Simple assertions
+

+

+The final use of backslash is for certain simple assertions. An assertion
+specifies a condition that has to be met at a particular point in a match,
+without consuming any characters from the subject string. The use of
+groups for more complicated assertions is described
+below.
+The backslashed assertions are:
+
+  \b     matches at a word boundary
+  \B     matches when not at a word boundary
+  \A     matches at the start of the subject
+  \Z     matches at the end of the subject
+          also matches before a newline at the end of the subject
+  \z     matches only at the end of the subject
+  \G     matches at the first matching position in the subject
+

+Inside a character class, \b has a different meaning; it matches the backspace
+character. If any other of these assertions appears in a character class, an
+"invalid escape sequence" error is generated.
+

+

+A word boundary is a position in the subject string where the current character
+and the previous character do not both match \w or \W (i.e. one matches
+\w and the other matches \W), or the start or end of the string if the
+first or last character matches \w, respectively. When PCRE2 is built with
+Unicode support, the meanings of \w and \W can be changed by setting the
+PCRE2_UCP option. When this is done, it also affects \b and \B. Neither PCRE2
+nor Perl has a separate "start of word" or "end of word" metasequence. However,
+whatever follows \b normally determines which it is. For example, the fragment
+\ba matches "a" at the start of a word.
+

+

+The \A, \Z, and \z assertions differ from the traditional circumflex and
+dollar (described in the next section) in that they only ever match at the very
+start and end of the subject string, whatever options are set. Thus, they are
+independent of multiline mode. These three assertions are not affected by the
+PCRE2_NOTBOL or PCRE2_NOTEOL options, which affect only the behaviour of the
+circumflex and dollar metacharacters. However, if the startoffset
+argument of pcre2_match() is non-zero, indicating that matching is to
+start at a point other than the beginning of the subject, \A can never match.
+The difference between \Z and \z is that \Z matches before a newline at the
+end of the string as well as at the very end, whereas \z matches only at the
+end.
+

+

+The \G assertion is true only when the current matching position is at the
+start point of the matching process, as specified by the startoffset
+argument of pcre2_match(). It differs from \A when the value of
+startoffset is non-zero. By calling pcre2_match() multiple times
+with appropriate arguments, you can mimic Perl's /g option, and it is in this
+kind of implementation where \G can be useful.
+

+

+Note, however, that PCRE2's implementation of \G, being true at the starting
+character of the matching process, is subtly different from Perl's, which
+defines it as true at the end of the previous match. In Perl, these can be
+different when the previously matched string was empty. Because PCRE2 does just
+one match at a time, it cannot reproduce this behaviour.
+

+

+If all the alternatives of a pattern begin with \G, the expression is anchored
+to the starting match position, and the "anchored" flag is set in the compiled
+regular expression.
+

+
CIRCUMFLEX AND DOLLAR

+

+The circumflex and dollar metacharacters are zero-width assertions. That is,
+they test for a particular condition being true without consuming any
+characters from the subject string. These two metacharacters are concerned with
+matching the starts and ends of lines. If the newline convention is set so that
+only the two-character sequence CRLF is recognized as a newline, isolated CR
+and LF characters are treated as ordinary data characters, and are not
+recognized as newlines.
+

+

+Outside a character class, in the default matching mode, the circumflex
+character is an assertion that is true only if the current matching point is at
+the start of the subject string. If the startoffset argument of
+pcre2_match() is non-zero, or if PCRE2_NOTBOL is set, circumflex can
+never match if the PCRE2_MULTILINE option is unset. Inside a character class,
+circumflex has an entirely different meaning
+(see below).
+

+

+Circumflex need not be the first character of the pattern if a number of
+alternatives are involved, but it should be the first thing in each alternative
+in which it appears if the pattern is ever to match that branch. If all
+possible alternatives start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is said to be an
+"anchored" pattern. (There are also other constructs that can cause a pattern
+to be anchored.)
+

+

+The dollar character is an assertion that is true only if the current matching
+point is at the end of the subject string, or immediately before a newline at
+the end of the string (by default), unless PCRE2_NOTEOL is set. Note, however,
+that it does not actually match the newline. Dollar need not be the last
+character of the pattern if a number of alternatives are involved, but it
+should be the last item in any branch in which it appears. Dollar has no
+special meaning in a character class.
+

+

+The meaning of dollar can be changed so that it matches only at the very end of
+the string, by setting the PCRE2_DOLLAR_ENDONLY option at compile time. This
+does not affect the \Z assertion.
+

+

+The meanings of the circumflex and dollar metacharacters are changed if the
+PCRE2_MULTILINE option is set. When this is the case, a dollar character
+matches before any newlines in the string, as well as at the very end, and a
+circumflex matches immediately after internal newlines as well as at the start
+of the subject string. It does not match after a newline that ends the string,
+for compatibility with Perl. However, this can be changed by setting the
+PCRE2_ALT_CIRCUMFLEX option.
+

+

+For example, the pattern /^abc$/ matches the subject string "def\nabc" (where
+\n represents a newline) in multiline mode, but not otherwise. Consequently,
+patterns that are anchored in single line mode because all branches start with
+^ are not anchored in multiline mode, and a match for circumflex is possible
+when the startoffset argument of pcre2_match() is non-zero. The
+PCRE2_DOLLAR_ENDONLY option is ignored if PCRE2_MULTILINE is set.
+

+

+When the newline convention (see
+"Newline conventions"
+below) recognizes the two-character sequence CRLF as a newline, this is
+preferred, even if the single characters CR and LF are also recognized as
+newlines. For example, if the newline convention is "any", a multiline mode
+circumflex matches before "xyz" in the string "abc\r\nxyz" rather than after
+CR, even though CR on its own is a valid newline. (It also matches at the very
+start of the string, of course.)
+

+

+Note that the sequences \A, \Z, and \z can be used to match the start and
+end of the subject in both modes, and if all branches of a pattern start with
+\A it is always anchored, whether or not PCRE2_MULTILINE is set.
+

+
FULL STOP (PERIOD, DOT) AND \N

+

+Outside a character class, a dot in the pattern matches any one character in
+the subject string except (by default) a character that signifies the end of a
+line. One or more characters may be specified as line terminators (see
+"Newline conventions"
+above).
+

+

+Dot never matches a single line-ending character. When the two-character
+sequence CRLF is the only line ending, dot does not match CR if it is
+immediately followed by LF, but otherwise it matches all characters (including
+isolated CRs and LFs). When ANYCRLF is selected for line endings, no occurrences
+of CR of LF match dot. When all Unicode line endings are being recognized, dot
+does not match CR or LF or any of the other line ending characters.
+

+

+The behaviour of dot with regard to newlines can be changed. If the
+PCRE2_DOTALL option is set, a dot matches any one character, without exception.
+If the two-character sequence CRLF is present in the subject string, it takes
+two dots to match it.
+

+

+The handling of dot is entirely independent of the handling of circumflex and
+dollar, the only relationship being that they both involve newlines. Dot has no
+special meaning in a character class.
+

+

+The escape sequence \N when not followed by an opening brace behaves like a
+dot, except that it is not affected by the PCRE2_DOTALL option. In other words,
+it matches any character except one that signifies the end of a line.
+

+

+When \N is followed by an opening brace it has a different meaning. See the
+section entitled
+"Non-printing characters"
+above for details. Perl also uses \N{name} to specify characters by Unicode
+name; PCRE2 does not support this.
+

+
MATCHING A SINGLE CODE UNIT

+

+Outside a character class, the escape sequence \C matches any one code unit,
+whether or not a UTF mode is set. In the 8-bit library, one code unit is one
+byte; in the 16-bit library it is a 16-bit unit; in the 32-bit library it is a
+32-bit unit. Unlike a dot, \C always matches line-ending characters. The
+feature is provided in Perl in order to match individual bytes in UTF-8 mode,
+but it is unclear how it can usefully be used.
+

+

+Because \C breaks up characters into individual code units, matching one unit
+with \C in UTF-8 or UTF-16 mode means that the rest of the string may start
+with a malformed UTF character. This has undefined results, because PCRE2
+assumes that it is matching character by character in a valid UTF string (by
+default it checks the subject string's validity at the start of processing
+unless the PCRE2_NO_UTF_CHECK or PCRE2_MATCH_INVALID_UTF option is used).
+

+

+An application can lock out the use of \C by setting the
+PCRE2_NEVER_BACKSLASH_C option when compiling a pattern. It is also possible to
+build PCRE2 with the use of \C permanently disabled.
+

+

+PCRE2 does not allow \C to appear in lookbehind assertions
+(described below)
+in UTF-8 or UTF-16 modes, because this would make it impossible to calculate
+the length of the lookbehind. Neither the alternative matching function
+pcre2_dfa_match() nor the JIT optimizer support \C in these UTF modes.
+The former gives a match-time error; the latter fails to optimize and so the
+match is always run using the interpreter.
+

+

+In the 32-bit library, however, \C is always supported (when not explicitly
+locked out) because it always matches a single code unit, whether or not UTF-32
+is specified.
+

+

+In general, the \C escape sequence is best avoided. However, one way of using
+it that avoids the problem of malformed UTF-8 or UTF-16 characters is to use a
+lookahead to check the length of the next character, as in this pattern, which
+could be used with a UTF-8 string (ignore white space and line breaks):
+
+  (?| (?=[\x00-\x7f])(\C) |
+      (?=[\x80-\x{7ff}])(\C)(\C) |
+      (?=[\x{800}-\x{ffff}])(\C)(\C)(\C) |
+      (?=[\x{10000}-\x{1fffff}])(\C)(\C)(\C)(\C))
+

+In this example, a group that starts with (?| resets the capturing parentheses
+numbers in each alternative (see
+"Duplicate Group Numbers"
+below). The assertions at the start of each branch check the next UTF-8
+character for values whose encoding uses 1, 2, 3, or 4 bytes, respectively. The
+character's individual bytes are then captured by the appropriate number of
+\C groups.
+

+
SQUARE BRACKETS AND CHARACTER CLASSES

+

+An opening square bracket introduces a character class, terminated by a closing
+square bracket. A closing square bracket on its own is not special by default.
+If a closing square bracket is required as a member of the class, it should be
+the first data character in the class (after an initial circumflex, if present)
+or escaped with a backslash. This means that, by default, an empty class cannot
+be defined. However, if the PCRE2_ALLOW_EMPTY_CLASS option is set, a closing
+square bracket at the start does end the (empty) class.
+

+

+A character class matches a single character in the subject. A matched
+character must be in the set of characters defined by the class, unless the
+first character in the class definition is a circumflex, in which case the
+subject character must not be in the set defined by the class. If a circumflex
+is actually required as a member of the class, ensure it is not the first
+character, or escape it with a backslash.
+

+

+For example, the character class [aeiou] matches any lower case vowel, while
+[^aeiou] matches any character that is not a lower case vowel. Note that a
+circumflex is just a convenient notation for specifying the characters that
+are in the class by enumerating those that are not. A class that starts with a
+circumflex is not an assertion; it still consumes a character from the subject
+string, and therefore it fails if the current pointer is at the end of the
+string.
+

+

+Characters in a class may be specified by their code points using \o, \x, or
+\N{U+hh..} in the usual way. When caseless matching is set, any letters in a
+class represent both their upper case and lower case versions, so for example,
+a caseless [aeiou] matches "A" as well as "a", and a caseless [^aeiou] does not
+match "A", whereas a caseful version would. Note that there are two ASCII
+characters, K and S, that, in addition to their lower case ASCII equivalents,
+are case-equivalent with Unicode U+212A (Kelvin sign) and U+017F (long S)
+respectively when either PCRE2_UTF or PCRE2_UCP is set.
+

+

+Characters that might indicate line breaks are never treated in any special way
+when matching character classes, whatever line-ending sequence is in use, and
+whatever setting of the PCRE2_DOTALL and PCRE2_MULTILINE options is used. A
+class such as [^a] always matches one of these characters.
+

+

+The generic character type escape sequences \d, \D, \h, \H, \p, \P, \s,
+\S, \v, \V, \w, and \W may appear in a character class, and add the
+characters that they match to the class. For example, [\dABCDEF] matches any
+hexadecimal digit. In UTF modes, the PCRE2_UCP option affects the meanings of
+\d, \s, \w and their upper case partners, just as it does when they appear
+outside a character class, as described in the section entitled
+"Generic character types"
+above. The escape sequence \b has a different meaning inside a character
+class; it matches the backspace character. The sequences \B, \R, and \X are
+not special inside a character class. Like any other unrecognized escape
+sequences, they cause an error. The same is true for \N when not followed by
+an opening brace.
+

+

+The minus (hyphen) character can be used to specify a range of characters in a
+character class. For example, [d-m] matches any letter between d and m,
+inclusive. If a minus character is required in a class, it must be escaped with
+a backslash or appear in a position where it cannot be interpreted as
+indicating a range, typically as the first or last character in the class,
+or immediately after a range. For example, [b-d-z] matches letters in the range
+b to d, a hyphen character, or z.
+

+

+Perl treats a hyphen as a literal if it appears before or after a POSIX class
+(see below) or before or after a character type escape such as \d or \H.
+However, unless the hyphen is the last character in the class, Perl outputs a
+warning in its warning mode, as this is most likely a user error. As PCRE2 has
+no facility for warning, an error is given in these cases.
+

+

+It is not possible to have the literal character "]" as the end character of a
+range. A pattern such as [W-]46] is interpreted as a class of two characters
+("W" and "-") followed by a literal string "46]", so it would match "W46]" or
+"-46]". However, if the "]" is escaped with a backslash it is interpreted as
+the end of range, so [W-\]46] is interpreted as a class containing a range
+followed by two other characters. The octal or hexadecimal representation of
+"]" can also be used to end a range.
+

+

+Ranges normally include all code points between the start and end characters,
+inclusive. They can also be used for code points specified numerically, for
+example [\000-\037]. Ranges can include any characters that are valid for the
+current mode. In any UTF mode, the so-called "surrogate" characters (those
+whose code points lie between 0xd800 and 0xdfff inclusive) may not be specified
+explicitly by default (the PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES option disables
+this check). However, ranges such as [\x{d7ff}-\x{e000}], which include the
+surrogates, are always permitted.
+

+

+There is a special case in EBCDIC environments for ranges whose end points are
+both specified as literal letters in the same case. For compatibility with
+Perl, EBCDIC code points within the range that are not letters are omitted. For
+example, [h-k] matches only four characters, even though the codes for h and k
+are 0x88 and 0x92, a range of 11 code points. However, if the range is
+specified numerically, for example, [\x88-\x92] or [h-\x92], all code points
+are included.
+

+

+If a range that includes letters is used when caseless matching is set, it
+matches the letters in either case. For example, [W-c] is equivalent to
+[][\\^_`wxyzabc], matched caselessly, and in a non-UTF mode, if character
+tables for a French locale are in use, [\xc8-\xcb] matches accented E
+characters in both cases.
+

+

+A circumflex can conveniently be used with the upper case character types to
+specify a more restricted set of characters than the matching lower case type.
+For example, the class [^\W_] matches any letter or digit, but not underscore,
+whereas [\w] includes underscore. A positive character class should be read as
+"something OR something OR ..." and a negative class as "NOT something AND NOT
+something AND NOT ...".
+

+

+The only metacharacters that are recognized in character classes are backslash,
+hyphen (only where it can be interpreted as specifying a range), circumflex
+(only at the start), opening square bracket (only when it can be interpreted as
+introducing a POSIX class name, or for a special compatibility feature - see
+the next two sections), and the terminating closing square bracket. However,
+escaping other non-alphanumeric characters does no harm.
+

+
POSIX CHARACTER CLASSES

+

+Perl supports the POSIX notation for character classes. This uses names
+enclosed by [: and :] within the enclosing square brackets. PCRE2 also supports
+this notation. For example,
+
+  [01[:alpha:]%]
+

+matches "0", "1", any alphabetic character, or "%". The supported class names
+are:
+
+  alnum    letters and digits
+  alpha    letters
+  ascii    character codes 0 - 127
+  blank    space or tab only
+  cntrl    control characters
+  digit    decimal digits (same as \d)
+  graph    printing characters, excluding space
+  lower    lower case letters
+  print    printing characters, including space
+  punct    printing characters, excluding letters and digits and space
+  space    white space (the same as \s from PCRE2 8.34)
+  upper    upper case letters
+  word     "word" characters (same as \w)
+  xdigit   hexadecimal digits
+

+The default "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13),
+and space (32). If locale-specific matching is taking place, the list of space
+characters may be different; there may be fewer or more of them. "Space" and
+\s match the same set of characters, as do "word" and \w.
+

+

+The name "word" is a Perl extension, and "blank" is a GNU extension from Perl
+5.8. Another Perl extension is negation, which is indicated by a ^ character
+after the colon. For example,
+
+  [12[:^digit:]]
+

+matches "1", "2", or any non-digit. PCRE2 (and Perl) also recognize the POSIX
+syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not
+supported, and an error is given if they are encountered.
+

+

+By default, characters with values greater than 127 do not match any of the
+POSIX character classes, although this may be different for characters in the
+range 128-255 when locale-specific matching is happening. However, in UCP mode,
+unless certain options are set (see below), some of the classes are changed so
+that Unicode character properties are used. This is achieved by replacing
+POSIX classes with other sequences, as follows:
+
+  [:alnum:]  becomes  \p{Xan}
+  [:alpha:]  becomes  \p{L}
+  [:blank:]  becomes  \h
+  [:cntrl:]  becomes  \p{Cc}
+  [:digit:]  becomes  \p{Nd}
+  [:lower:]  becomes  \p{Ll}
+  [:space:]  becomes  \p{Xps}
+  [:upper:]  becomes  \p{Lu}
+  [:word:]   becomes  \p{Xwd}
+

+Negated versions, such as [:^alpha:] use \P instead of \p. Four other POSIX
+classes are handled specially in UCP mode:
+

+

+[:graph:]
+This matches characters that have glyphs that mark the page when printed. In
+Unicode property terms, it matches all characters with the L, M, N, P, S, or Cf
+properties, except for:
+
+  U+061C           Arabic Letter Mark
+  U+180E           Mongolian Vowel Separator
+  U+2066 - U+2069  Various "isolate"s
+
+

+

+

+[:print:]
+This matches the same characters as [:graph:] plus space characters that are
+not controls, that is, characters with the Zs property.
+

+

+[:punct:]
+This matches all characters that have the Unicode P (punctuation) property,
+plus those characters with code points less than 256 that have the S (Symbol)
+property.
+

+

+[:xdigit:]
+In addition to the ASCII hexadecimal digits, this also matches the "fullwidth"
+versions of those characters, whose Unicode code points start at U+FF10. This
+is a change that was made in PCRE release 10.43 for Perl compatibility.
+

+

+The other POSIX classes are unchanged by PCRE2_UCP, and match only characters
+with code points less than 256.
+

+

+There are two options that can be used to restrict the POSIX classes to ASCII
+characters when PCRE2_UCP is set. The option PCRE2_EXTRA_ASCII_DIGIT affects
+just [:digit:] and [:xdigit:]. Within a pattern, this can be set and unset by
+(?aT) and (?-aT). The PCRE2_EXTRA_ASCII_POSIX option disables UCP processing
+for all POSIX classes, including [:digit:] and [:xdigit:]. Within a pattern,
+(?aP) and (?-aP) set and unset both these options for consistency.
+

+
COMPATIBILITY FEATURE FOR WORD BOUNDARIES

+

+In the POSIX.2 compliant library that was included in 4.4BSD Unix, the ugly
+syntax [[:<:]] and [[:>:]] is used for matching "start of word" and "end of
+word". PCRE2 treats these items as follows:
+
+  [[:<:]]  is converted to  \b(?=\w)
+  [[:>:]]  is converted to  \b(?<=\w)
+

+Only these exact character sequences are recognized. A sequence such as
+[a[:<:]b] provokes error for an unrecognized POSIX class name. This support is
+not compatible with Perl. It is provided to help migrations from other
+environments, and is best not used in any new patterns. Note that \b matches
+at the start and the end of a word (see
+"Simple assertions"
+above), and in a Perl-style pattern the preceding or following character
+normally shows which is wanted, without the need for the assertions that are
+used above in order to give exactly the POSIX behaviour. Note also that the
+PCRE2_UCP option changes the meaning of \w (and therefore \b) by default, so
+it also affects these POSIX sequences.
+

+
VERTICAL BAR

+

+Vertical bar characters are used to separate alternative patterns. For example,
+the pattern
+
+  gilbert|sullivan
+

+matches either "gilbert" or "sullivan". Any number of alternatives may appear,
+and an empty alternative is permitted (matching the empty string). The matching
+process tries each alternative in turn, from left to right, and the first one
+that succeeds is used. If the alternatives are within a group
+(defined below),
+"succeeds" means matching the rest of the main pattern as well as the
+alternative in the group.
+

+
INTERNAL OPTION SETTING

+

+The settings of several options can be changed within a pattern by a sequence
+of letters enclosed between "(?" and ")". The following are Perl-compatible,
+and are described in detail in the
+pcre2api
+documentation. The option letters are:
+
+  i  for PCRE2_CASELESS
+  m  for PCRE2_MULTILINE
+  n  for PCRE2_NO_AUTO_CAPTURE
+  s  for PCRE2_DOTALL
+  x  for PCRE2_EXTENDED
+  xx for PCRE2_EXTENDED_MORE
+

+For example, (?im) sets caseless, multiline matching. It is also possible to
+unset these options by preceding the relevant letters with a hyphen, for
+example (?-im). The two "extended" options are not independent; unsetting
+either one cancels the effects of both of them.
+

+

+A combined setting and unsetting such as (?im-sx), which sets PCRE2_CASELESS
+and PCRE2_MULTILINE while unsetting PCRE2_DOTALL and PCRE2_EXTENDED, is also
+permitted. Only one hyphen may appear in the options string. If a letter
+appears both before and after the hyphen, the option is unset. An empty options
+setting "(?)" is allowed. Needless to say, it has no effect.
+

+

+If the first character following (? is a circumflex, it causes all of the above
+options to be unset. Letters may follow the circumflex to cause some options to
+be re-instated, but a hyphen may not appear.
+

+

+Some PCRE2-specific options can be changed by the same mechanism using these
+pairs or individual letters:
+
+  aD for PCRE2_EXTRA_ASCII_BSD
+  aS for PCRE2_EXTRA_ASCII_BSS
+  aW for PCRE2_EXTRA_ASCII_BSW
+  aP for PCRE2_EXTRA_ASCII_POSIX and PCRE2_EXTRA_ASCII_DIGIT
+  aT for PCRE2_EXTRA_ASCII_DIGIT
+  r  for PCRE2_EXTRA_CASELESS_RESTRICT
+  J  for PCRE2_DUPNAMES
+  U  for PCRE2_UNGREEDY
+

+However, except for 'r', these are not unset by (?^), which is equivalent to
+(?-imnrsx). If 'a' is not followed by any of the upper case letters shown
+above, it sets (or unsets) all the ASCII options.
+

+

+PCRE2_EXTRA_ASCII_DIGIT has no additional effect when PCRE2_EXTRA_ASCII_POSIX
+is set, but including it in (?aP) means that (?-aP) suppresses all ASCII
+restrictions for POSIX classes.
+

+

+When one of these option changes occurs at top level (that is, not inside group
+parentheses), the change applies until a subsequent change, or the end of the
+pattern. An option change within a group (see below for a description of
+groups) affects only that part of the group that follows it. At the end of the
+group these options are reset to the state they were before the group. For
+example,
+
+  (a(?i)b)c
+

+matches abc and aBc and no other strings (assuming PCRE2_CASELESS is not set
+externally). Any changes made in one alternative do carry on into subsequent
+branches within the same group. For example,
+
+  (a(?i)b|c)
+

+matches "ab", "aB", "c", and "C", even though when matching "C" the first
+branch is abandoned before the option setting. This is because the effects of
+option settings happen at compile time. There would be some very weird
+behaviour otherwise.
+

+

+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing group (see the next section), the option letters may
+appear between the "?" and the ":". Thus the two patterns
+
+  (?i:saturday|sunday)
+  (?:(?i)saturday|sunday)
+

+match exactly the same set of strings.
+

+

+Note: There are other PCRE2-specific options, applying to the whole
+pattern, which can be set by the application when the compiling function is
+called. In addition, the pattern can contain special leading sequences such as
+(*CRLF) to override what the application has set or what has been defaulted.
+Details are given in the section entitled
+"Newline sequences"
+above. There are also the (*UTF) and (*UCP) leading sequences that can be used
+to set UTF and Unicode property modes; they are equivalent to setting the
+PCRE2_UTF and PCRE2_UCP options, respectively. However, the application can set
+the PCRE2_NEVER_UTF or PCRE2_NEVER_UCP options, which lock out the use of the
+(*UTF) and (*UCP) sequences.
+

+
GROUPS

+

+Groups are delimited by parentheses (round brackets), which can be nested.
+Turning part of a pattern into a group does two things:
+

+

+1. It localizes a set of alternatives. For example, the pattern
+
+  cat(aract|erpillar|)
+

+matches "cataract", "caterpillar", or "cat". Without the parentheses, it would
+match "cataract", "erpillar" or an empty string.
+

+

+2. It creates a "capture group". This means that, when the whole pattern
+matches, the portion of the subject string that matched the group is passed
+back to the caller, separately from the portion that matched the whole pattern.
+(This applies only to the traditional matching function; the DFA matching
+function does not support capturing.)
+

+

+Opening parentheses are counted from left to right (starting from 1) to obtain
+numbers for capture groups. For example, if the string "the red king" is
+matched against the pattern
+
+  the ((red|white) (king|queen))
+

+the captured substrings are "red king", "red", and "king", and are numbered 1,
+2, and 3, respectively.
+

+

+The fact that plain parentheses fulfil two functions is not always helpful.
+There are often times when grouping is required without capturing. If an
+opening parenthesis is followed by a question mark and a colon, the group
+does not do any capturing, and is not counted when computing the number of any
+subsequent capture groups. For example, if the string "the white queen"
+is matched against the pattern
+
+  the ((?:red|white) (king|queen))
+

+the captured substrings are "white queen" and "queen", and are numbered 1 and
+2. The maximum number of capture groups is 65535.
+

+

+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing group, the option letters may appear between the "?" and the
+":". Thus the two patterns
+
+  (?i:saturday|sunday)
+  (?:(?i)saturday|sunday)
+

+match exactly the same set of strings. Because alternative branches are tried
+from left to right, and options are not reset until the end of the group is
+reached, an option setting in one branch does affect subsequent branches, so
+the above patterns match "SUNDAY" as well as "Saturday".
+

+
DUPLICATE GROUP NUMBERS

+

+Perl 5.10 introduced a feature whereby each alternative in a group uses the
+same numbers for its capturing parentheses. Such a group starts with (?| and is
+itself a non-capturing group. For example, consider this pattern:
+
+  (?|(Sat)ur|(Sun))day
+

+Because the two alternatives are inside a (?| group, both sets of capturing
+parentheses are numbered one. Thus, when the pattern matches, you can look
+at captured substring number one, whichever alternative matched. This construct
+is useful when you want to capture part, but not all, of one of a number of
+alternatives. Inside a (?| group, parentheses are numbered as usual, but the
+number is reset at the start of each branch. The numbers of any capturing
+parentheses that follow the whole group start after the highest number used in
+any branch. The following example is taken from the Perl documentation. The
+numbers underneath show in which buffer the captured content will be stored.
+
+  # before  ---------------branch-reset----------- after
+  / ( a )  (?| x ( y ) z | (p (q) r) | (t) u (v) ) ( z ) /x
+  # 1            2         2  3        2     3     4
+

+A backreference to a capture group uses the most recent value that is set for
+the group. The following pattern matches "abcabc" or "defdef":
+
+  /(?|(abc)|(def))\1/
+

+In contrast, a subroutine call to a capture group always refers to the
+first one in the pattern with the given number. The following pattern matches
+"abcabc" or "defabc":
+
+  /(?|(abc)|(def))(?1)/
+

+A relative reference such as (?-1) is no different: it is just a convenient way
+of computing an absolute group number.
+

+

+If a
+condition test
+for a group's having matched refers to a non-unique number, the test is
+true if any group with that number has matched.
+

+

+An alternative approach to using this "branch reset" feature is to use
+duplicate named groups, as described in the next section.
+

+
NAMED CAPTURE GROUPS

+

+Identifying capture groups by number is simple, but it can be very hard to keep
+track of the numbers in complicated patterns. Furthermore, if an expression is
+modified, the numbers may change. To help with this difficulty, PCRE2 supports
+the naming of capture groups. This feature was not added to Perl until release
+5.10. Python had the feature earlier, and PCRE1 introduced it at release 4.0,
+using the Python syntax. PCRE2 supports both the Perl and the Python syntax.
+

+

+In PCRE2, a capture group can be named in one of three ways: (?<name>...) or
+(?'name'...) as in Perl, or (?P<name>...) as in Python. Names may be up to 128
+code units long. When PCRE2_UTF is not set, they may contain only ASCII
+alphanumeric characters and underscores, but must start with a non-digit. When
+PCRE2_UTF is set, the syntax of group names is extended to allow any Unicode
+letter or Unicode decimal digit. In other words, group names must match one of
+these patterns:
+
+  ^[_A-Za-z][_A-Za-z0-9]*\z   when PCRE2_UTF is not set
+  ^[_\p{L}][_\p{L}\p{Nd}]*\z  when PCRE2_UTF is set
+

+References to capture groups from other parts of the pattern, such as
+backreferences,
+recursion,
+and
+conditions,
+can all be made by name as well as by number.
+

+

+Named capture groups are allocated numbers as well as names, exactly as
+if the names were not present. In both PCRE2 and Perl, capture groups
+are primarily identified by numbers; any names are just aliases for these
+numbers. The PCRE2 API provides function calls for extracting the complete
+name-to-number translation table from a compiled pattern, as well as
+convenience functions for extracting captured substrings by name.
+

+

+Warning: When more than one capture group has the same number, as
+described in the previous section, a name given to one of them applies to all
+of them. Perl allows identically numbered groups to have different names.
+Consider this pattern, where there are two capture groups, both numbered 1:
+
+  (?|(?<AA>aa)|(?<BB>bb))
+

+Perl allows this, with both names AA and BB as aliases of group 1. Thus, after
+a successful match, both names yield the same value (either "aa" or "bb").
+

+

+In an attempt to reduce confusion, PCRE2 does not allow the same group number
+to be associated with more than one name. The example above provokes a
+compile-time error. However, there is still scope for confusion. Consider this
+pattern:
+
+  (?|(?<AA>aa)|(bb))
+

+Although the second group number 1 is not explicitly named, the name AA is
+still an alias for any group 1. Whether the pattern matches "aa" or "bb", a
+reference by name to group AA yields the matched string.
+

+

+By default, a name must be unique within a pattern, except that duplicate names
+are permitted for groups with the same number, for example:
+
+  (?|(?<AA>aa)|(?<AA>bb))
+

+The duplicate name constraint can be disabled by setting the PCRE2_DUPNAMES
+option at compile time, or by the use of (?J) within the pattern, as described
+in the section entitled
+"Internal Option Setting"
+above.
+

+

+Duplicate names can be useful for patterns where only one instance of the named
+capture group can match. Suppose you want to match the name of a weekday,
+either as a 3-letter abbreviation or as the full name, and in both cases you
+want to extract the abbreviation. This pattern (ignoring the line breaks) does
+the job:
+
+  (?J)
+  (?<DN>Mon|Fri|Sun)(?:day)?|
+  (?<DN>Tue)(?:sday)?|
+  (?<DN>Wed)(?:nesday)?|
+  (?<DN>Thu)(?:rsday)?|
+  (?<DN>Sat)(?:urday)?
+

+There are five capture groups, but only one is ever set after a match. The
+convenience functions for extracting the data by name returns the substring for
+the first (and in this example, the only) group of that name that matched. This
+saves searching to find which numbered group it was. (An alternative way of
+solving this problem is to use a "branch reset" group, as described in the
+previous section.)
+

+

+If you make a backreference to a non-unique named group from elsewhere in the
+pattern, the groups to which the name refers are checked in the order in which
+they appear in the overall pattern. The first one that is set is used for the
+reference. For example, this pattern matches both "foofoo" and "barbar" but not
+"foobar" or "barfoo":
+
+  (?J)(?:(?<n>foo)|(?<n>bar))\k<n>
+
+

+

+

+If you make a subroutine call to a non-unique named group, the one that
+corresponds to the first occurrence of the name is used. In the absence of
+duplicate numbers this is the one with the lowest number.
+

+

+If you use a named reference in a condition
+test (see the
+section about conditions
+below), either to check whether a capture group has matched, or to check for
+recursion, all groups with the same name are tested. If the condition is true
+for any one of them, the overall condition is true. This is the same behaviour
+as testing by number. For further details of the interfaces for handling named
+capture groups, see the
+pcre2api
+documentation.
+

+
REPETITION

+

+Repetition is specified by quantifiers, which may follow any one of these
+items:
+
+  a literal data character
+  the dot metacharacter
+  the \C escape sequence
+  the \R escape sequence
+  the \X escape sequence
+  any escape sequence that matches a single character
+  a character class
+  a backreference
+  a parenthesized group (including lookaround assertions)
+  a subroutine call (recursive or otherwise)
+

+If a quantifier does not follow a repeatable item, an error occurs. The
+general repetition quantifier specifies a minimum and maximum number of
+permitted matches by giving two numbers in curly brackets (braces), separated
+by a comma. The numbers must be less than 65536, and the first must be less
+than or equal to the second. For example,
+
+  z{2,4}
+

+matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special
+character. If the second number is omitted, but the comma is present, there is
+no upper limit; if the second number and the comma are both omitted, the
+quantifier specifies an exact number of required matches. Thus
+
+  [aeiou]{3,}
+

+matches at least 3 successive vowels, but may match many more, whereas
+
+  \d{8}
+

+matches exactly 8 digits. If the first number is omitted, the lower limit is
+taken as zero; in this case the upper limit must be present.
+
+  X{,4} is interpreted as X{0,4}
+

+This is a change in behaviour that happened in Perl 5.34.0 and PCRE2 10.43. In
+earlier versions such a sequence was not interpreted as a quantifier. Other
+regular expression engines may behave either way.
+

+

+If the characters that follow an opening brace do not match the syntax of a
+quantifier, the brace is taken as a literal character. In particular, this
+means that {,} is a literal string of three characters.
+

+

+Note that not every opening brace is potentially the start of a quantifier
+because braces are used in other items such as \N{U+345} or \k{name}.
+

+

+In UTF modes, quantifiers apply to characters rather than to individual code
+units. Thus, for example, \x{100}{2} matches two characters, each of
+which is represented by a two-byte sequence in a UTF-8 string. Similarly,
+\X{3} matches three Unicode extended grapheme clusters, each of which may be
+several code units long (and they may be of different lengths).
+

+

+The quantifier {0} is permitted, causing the expression to behave as if the
+previous item and the quantifier were not present. This may be useful for
+capture groups that are referenced as
+subroutines
+from elsewhere in the pattern (but see also the section entitled
+"Defining capture groups for use by reference only"
+below). Except for parenthesized groups, items that have a {0} quantifier are
+omitted from the compiled pattern.
+

+

+For convenience, the three most common quantifiers have single-character
+abbreviations:
+
+  *    is equivalent to {0,}
+  +    is equivalent to {1,}
+  ?    is equivalent to {0,1}
+

+It is possible to construct infinite loops by following a group that can match
+no characters with a quantifier that has no upper limit, for example:
+
+  (a?)*
+

+Earlier versions of Perl and PCRE1 used to give an error at compile time for
+such patterns. However, because there are cases where this can be useful, such
+patterns are now accepted, but whenever an iteration of such a group matches no
+characters, matching moves on to the next item in the pattern instead of
+repeatedly matching an empty string. This does not prevent backtracking into
+any of the iterations if a subsequent item fails to match.
+

+

+By default, quantifiers are "greedy", that is, they match as much as possible
+(up to the maximum number of permitted repetitions), without causing the rest
+of the pattern to fail. The classic example of where this gives problems is in
+trying to match comments in C programs. These appear between /* and */ and
+within the comment, individual * and / characters may appear. An attempt to
+match C comments by applying the pattern
+
+  /\*.*\*/
+

+to the string
+
+  /* first comment */  not comment  /* second comment */
+

+fails, because it matches the entire string owing to the greediness of the .*
+item. However, if a quantifier is followed by a question mark, it ceases to be
+greedy, and instead matches the minimum number of times possible, so the
+pattern
+
+  /\*.*?\*/
+

+does the right thing with C comments. The meaning of the various quantifiers is
+not otherwise changed, just the preferred number of matches. Do not confuse
+this use of question mark with its use as a quantifier in its own right.
+Because it has two uses, it can sometimes appear doubled, as in
+
+  \d??\d
+

+which matches one digit by preference, but can match two if that is the only
+way the rest of the pattern matches.
+

+

+If the PCRE2_UNGREEDY option is set (an option that is not available in Perl),
+the quantifiers are not greedy by default, but individual ones can be made
+greedy by following them with a question mark. In other words, it inverts the
+default behaviour.
+

+

+When a parenthesized group is quantified with a minimum repeat count that
+is greater than 1 or with a limited maximum, more memory is required for the
+compiled pattern, in proportion to the size of the minimum or maximum.
+

+

+If a pattern starts with .* or .{0,} and the PCRE2_DOTALL option (equivalent
+to Perl's /s) is set, thus allowing the dot to match newlines, the pattern is
+implicitly anchored, because whatever follows will be tried against every
+character position in the subject string, so there is no point in retrying the
+overall match at any position after the first. PCRE2 normally treats such a
+pattern as though it were preceded by \A.
+

+

+In cases where it is known that the subject string contains no newlines, it is
+worth setting PCRE2_DOTALL in order to obtain this optimization, or
+alternatively, using ^ to indicate anchoring explicitly.
+

+

+However, there are some cases where the optimization cannot be used. When .*
+is inside capturing parentheses that are the subject of a backreference
+elsewhere in the pattern, a match at the start may fail where a later one
+succeeds. Consider, for example:
+
+  (.*)abc\1
+

+If the subject is "xyz123abc123" the match point is the fourth character. For
+this reason, such a pattern is not implicitly anchored.
+

+

+Another case where implicit anchoring is not applied is when the leading .* is
+inside an atomic group. Once again, a match at the start may fail where a later
+one succeeds. Consider this pattern:
+
+  (?>.*?a)b
+

+It matches "ab" in the subject "aab". The use of the backtracking control verbs
+(*PRUNE) and (*SKIP) also disable this optimization, and there is an option,
+PCRE2_NO_DOTSTAR_ANCHOR, to do so explicitly.
+

+

+When a capture group is repeated, the value captured is the substring that
+matched the final iteration. For example, after
+
+  (tweedle[dume]{3}\s*)+
+

+has matched "tweedledum tweedledee" the value of the captured substring is
+"tweedledee". However, if there are nested capture groups, the corresponding
+captured values may have been set in previous iterations. For example, after
+
+  (a|(b))+
+

+matches "aba" the value of the second captured substring is "b".
+

+
ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS

+

+With both maximizing ("greedy") and minimizing ("ungreedy" or "lazy")
+repetition, failure of what follows normally causes the repeated item to be
+re-evaluated to see if a different number of repeats allows the rest of the
+pattern to match. Sometimes it is useful to prevent this, either to change the
+nature of the match, or to cause it fail earlier than it otherwise might, when
+the author of the pattern knows there is no point in carrying on.
+

+

+Consider, for example, the pattern \d+foo when applied to the subject line
+
+  123456bar
+

+After matching all 6 digits and then failing to match "foo", the normal
+action of the matcher is to try again with only 5 digits matching the \d+
+item, and then with 4, and so on, before ultimately failing. "Atomic grouping"
+(a term taken from Jeffrey Friedl's book) provides the means for specifying
+that once a group has matched, it is not to be re-evaluated in this way.
+

+

+If we use atomic grouping for the previous example, the matcher gives up
+immediately on failing to match "foo" the first time. The notation is a kind of
+special parenthesis, starting with (?> as in this example:
+
+  (?>\d+)foo
+

+Perl 5.28 introduced an experimental alphabetic form starting with (* which may
+be easier to remember:
+
+  (*atomic:\d+)foo
+

+This kind of parenthesized group "locks up" the part of the pattern it contains
+once it has matched, and a failure further into the pattern is prevented from
+backtracking into it. Backtracking past it to previous items, however, works as
+normal.
+

+

+An alternative description is that a group of this type matches exactly the
+string of characters that an identical standalone pattern would match, if
+anchored at the current point in the subject string.
+

+

+Atomic groups are not capture groups. Simple cases such as the above example
+can be thought of as a maximizing repeat that must swallow everything it can.
+So, while both \d+ and \d+? are prepared to adjust the number of digits they
+match in order to make the rest of the pattern match, (?>\d+) can only match
+an entire sequence of digits.
+

+

+Atomic groups in general can of course contain arbitrarily complicated
+expressions, and can be nested. However, when the contents of an atomic
+group is just a single repeated item, as in the example above, a simpler
+notation, called a "possessive quantifier" can be used. This consists of an
+additional + character following a quantifier. Using this notation, the
+previous example can be rewritten as
+
+  \d++foo
+

+Note that a possessive quantifier can be used with an entire group, for
+example:
+
+  (abc|xyz){2,3}+
+

+Possessive quantifiers are always greedy; the setting of the PCRE2_UNGREEDY
+option is ignored. They are a convenient notation for the simpler forms of
+atomic group. However, there is no difference in the meaning of a possessive
+quantifier and the equivalent atomic group, though there may be a performance
+difference; possessive quantifiers should be slightly faster.
+

+

+The possessive quantifier syntax is an extension to the Perl 5.8 syntax.
+Jeffrey Friedl originated the idea (and the name) in the first edition of his
+book. Mike McCloskey liked it, so implemented it when he built Sun's Java
+package, and PCRE1 copied it from there. It found its way into Perl at release
+5.10.
+

+

+PCRE2 has an optimization that automatically "possessifies" certain simple
+pattern constructs. For example, the sequence A+B is treated as A++B because
+there is no point in backtracking into a sequence of A's when B must follow.
+This feature can be disabled by the PCRE2_NO_AUTOPOSSESS option, or starting
+the pattern with (*NO_AUTO_POSSESS).
+

+

+When a pattern contains an unlimited repeat inside a group that can itself be
+repeated an unlimited number of times, the use of an atomic group is the only
+way to avoid some failing matches taking a very long time indeed. The pattern
+
+  (\D+|<\d+>)*[!?]
+

+matches an unlimited number of substrings that either consist of non-digits, or
+digits enclosed in <>, followed by either ! or ?. When it matches, it runs
+quickly. However, if it is applied to
+
+  aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+

+it takes a long time before reporting failure. This is because the string can
+be divided between the internal \D+ repeat and the external * repeat in a
+large number of ways, and all have to be tried. (The example uses [!?] rather
+than a single character at the end, because both PCRE2 and Perl have an
+optimization that allows for fast failure when a single character is used. They
+remember the last single character that is required for a match, and fail early
+if it is not present in the string.) If the pattern is changed so that it uses
+an atomic group, like this:
+
+  ((?>\D+)|<\d+>)*[!?]
+

+sequences of non-digits cannot be broken, and failure happens quickly.
+

+
BACKREFERENCES

+

+Outside a character class, a backslash followed by a digit greater than 0 (and
+possibly further digits) is a backreference to a capture group earlier (that
+is, to its left) in the pattern, provided there have been that many previous
+capture groups.
+

+

+However, if the decimal number following the backslash is less than 8, it is
+always taken as a backreference, and causes an error only if there are not that
+many capture groups in the entire pattern. In other words, the group that is
+referenced need not be to the left of the reference for numbers less than 8. A
+"forward backreference" of this type can make sense when a repetition is
+involved and the group to the right has participated in an earlier iteration.
+

+

+It is not possible to have a numerical "forward backreference" to a group whose
+number is 8 or more using this syntax because a sequence such as \50 is
+interpreted as a character defined in octal. See the subsection entitled
+"Non-printing characters"
+above
+for further details of the handling of digits following a backslash. Other
+forms of backreferencing do not suffer from this restriction. In particular,
+there is no problem when named capture groups are used (see below).
+

+

+Another way of avoiding the ambiguity inherent in the use of digits following a
+backslash is to use the \g escape sequence. This escape must be followed by a
+signed or unsigned number, optionally enclosed in braces. These examples are
+all identical:
+
+  (ring), \1
+  (ring), \g1
+  (ring), \g{1}
+

+An unsigned number specifies an absolute reference without the ambiguity that
+is present in the older syntax. It is also useful when literal digits follow
+the reference. A signed number is a relative reference. Consider this example:
+
+  (abc(def)ghi)\g{-1}
+

+The sequence \g{-1} is a reference to the capture group whose number is one
+less than the number of the next group to be started, so in this example (where
+the next group would be numbered 3) is it equivalent to \2, and \g{-2} would
+be equivalent to \1. Note that if this construct is inside a capture group,
+that group is included in the count, so in this example \g{-2} also refers to
+group 1:
+
+  (A)(\g{-2}B)
+

+The use of relative references can be helpful in long patterns, and also in
+patterns that are created by joining together fragments that contain references
+within themselves.
+

+

+The sequence \g{+1} is a reference to the next capture group that is started
+after this item, and \g{+2} refers to the one after that, and so on. This kind
+of forward reference can be useful in patterns that repeat. Perl does not
+support the use of + in this way.
+

+

+A backreference matches whatever actually most recently matched the capture
+group in the current subject string, rather than anything at all that matches
+the group (see
+"Groups as subroutines"
+below for a way of doing that). So the pattern
+
+  (sens|respons)e and \1ibility
+

+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If caseful matching is in force at the time of the
+backreference, the case of letters is relevant. For example,
+
+  ((?i)rah)\s+\1
+

+matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original
+capture group is matched caselessly.
+

+

+There are several different ways of writing backreferences to named capture
+groups. The .NET syntax is \k{name}, the Python syntax is (?=name), and the
+original Perl syntax is \k<name> or \k'name'. All of these are now supported
+by both Perl and PCRE2. Perl 5.10's unified backreference syntax, in which \g
+can be used for both numeric and named references, is also supported by PCRE2.
+We could rewrite the above example in any of the following ways:
+
+  (?<p1>(?i)rah)\s+\k<p1>
+  (?'p1'(?i)rah)\s+\k{p1}
+  (?P<p1>(?i)rah)\s+(?P=p1)
+  (?<p1>(?i)rah)\s+\g{p1}
+

+A capture group that is referenced by name may appear in the pattern before or
+after the reference.
+

+

+There may be more than one backreference to the same group. If a group has not
+actually been used in a particular match, backreferences to it always fail by
+default. For example, the pattern
+
+  (a|(bc))\2
+

+always fails if it starts to match "a" rather than "bc". However, if the
+PCRE2_MATCH_UNSET_BACKREF option is set at compile time, a backreference to an
+unset value matches an empty string.
+

+

+Because there may be many capture groups in a pattern, all digits following a
+backslash are taken as part of a potential backreference number. If the pattern
+continues with a digit character, some delimiter must be used to terminate the
+backreference. If the PCRE2_EXTENDED or PCRE2_EXTENDED_MORE option is set, this
+can be white space. Otherwise, the \g{} syntax or an empty comment (see
+"Comments"
+below) can be used.
+

+

+Recursive backreferences
+

+

+A backreference that occurs inside the group to which it refers fails when the
+group is first used, so, for example, (a\1) never matches. However, such
+references can be useful inside repeated groups. For example, the pattern
+
+  (a|b\1)+
+

+matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of
+the group, the backreference matches the character string corresponding to the
+previous iteration. In order for this to work, the pattern must be such that
+the first iteration does not need to match the backreference. This can be done
+using alternation, as in the example above, or by a quantifier with a minimum
+of zero.
+

+

+For versions of PCRE2 less than 10.25, backreferences of this type used to
+cause the group that they reference to be treated as an
+atomic group.
+This restriction no longer applies, and backtracking into such groups can occur
+as normal.
+

+
ASSERTIONS

+

+An assertion is a test on the characters following or preceding the current
+matching point that does not consume any characters. The simple assertions
+coded as \b, \B, \A, \G, \Z, \z, ^ and $ are described
+above.
+

+

+More complicated assertions are coded as parenthesized groups. There are two
+kinds: those that look ahead of the current position in the subject string, and
+those that look behind it, and in each case an assertion may be positive (must
+match for the assertion to be true) or negative (must not match for the
+assertion to be true). An assertion group is matched in the normal way,
+and if it is true, matching continues after it, but with the matching position
+in the subject string reset to what it was before the assertion was processed.
+

+

+The Perl-compatible lookaround assertions are atomic. If an assertion is true,
+but there is a subsequent matching failure, there is no backtracking into the
+assertion. However, there are some cases where non-atomic assertions can be
+useful. PCRE2 has some support for these, described in the section entitled
+"Non-atomic assertions"
+below, but they are not Perl-compatible.
+

+

+A lookaround assertion may appear as the condition in a
+conditional group
+(see below). In this case, the result of matching the assertion determines
+which branch of the condition is followed.
+

+

+Assertion groups are not capture groups. If an assertion contains capture
+groups within it, these are counted for the purposes of numbering the capture
+groups in the whole pattern. Within each branch of an assertion, locally
+captured substrings may be referenced in the usual way. For example, a sequence
+such as (.)\g{-1} can be used to check that two adjacent characters are the
+same.
+

+

+When a branch within an assertion fails to match, any substrings that were
+captured are discarded (as happens with any pattern branch that fails to
+match). A negative assertion is true only when all its branches fail to match;
+this means that no captured substrings are ever retained after a successful
+negative assertion. When an assertion contains a matching branch, what happens
+depends on the type of assertion.
+

+

+For a positive assertion, internally captured substrings in the successful
+branch are retained, and matching continues with the next pattern item after
+the assertion. For a negative assertion, a matching branch means that the
+assertion is not true. If such an assertion is being used as a condition in a
+conditional group
+(see below), captured substrings are retained, because matching continues with
+the "no" branch of the condition. For other failing negative assertions,
+control passes to the previous backtracking point, thus discarding any captured
+strings within the assertion.
+

+

+Most assertion groups may be repeated; though it makes no sense to assert the
+same thing several times, the side effect of capturing in positive assertions
+may occasionally be useful. However, an assertion that forms the condition for
+a conditional group may not be quantified. PCRE2 used to restrict the
+repetition of assertions, but from release 10.35 the only restriction is that
+an unlimited maximum repetition is changed to be one more than the minimum. For
+example, {3,} is treated as {3,4}.
+

+

+Alphabetic assertion names
+

+

+Traditionally, symbolic sequences such as (?= and (?<= have been used to
+specify lookaround assertions. Perl 5.28 introduced some experimental
+alphabetic alternatives which might be easier to remember. They all start with
+(* instead of (? and must be written using lower case letters. PCRE2 supports
+the following synonyms:
+
+  (*positive_lookahead:  or (*pla: is the same as (?=
+  (*negative_lookahead:  or (*nla: is the same as (?!
+  (*positive_lookbehind: or (*plb: is the same as (?<=
+  (*negative_lookbehind: or (*nlb: is the same as (?<!
+

+For example, (*pla:foo) is the same assertion as (?=foo). In the following
+sections, the various assertions are described using the original symbolic
+forms.
+

+

+Lookahead assertions
+

+

+Lookahead assertions start with (?= for positive assertions and (?! for
+negative assertions. For example,
+
+  \w+(?=;)
+

+matches a word followed by a semicolon, but does not include the semicolon in
+the match, and
+
+  foo(?!bar)
+

+matches any occurrence of "foo" that is not followed by "bar". Note that the
+apparently similar pattern
+
+  (?!foo)bar
+

+does not find an occurrence of "bar" that is preceded by something other than
+"foo"; it finds any occurrence of "bar" whatsoever, because the assertion
+(?!foo) is always true when the next three characters are "bar". A
+lookbehind assertion is needed to achieve the other effect.
+

+

+If you want to force a matching failure at some point in a pattern, the most
+convenient way to do it is with (?!) because an empty string always matches, so
+an assertion that requires there not to be an empty string must always fail.
+The backtracking control verb (*FAIL) or (*F) is a synonym for (?!).
+

+

+Lookbehind assertions
+

+

+Lookbehind assertions start with (?<= for positive assertions and (?<! for
+negative assertions. For example,
+
+  (?<!foo)bar
+

+does find an occurrence of "bar" that is not preceded by "foo". The contents of
+a lookbehind assertion are restricted such that there must be a known maximum
+to the lengths of all the strings it matches. There are two cases:
+

+

+If every top-level alternative matches a fixed length, for example
+
+  (?<=colour|color)
+

+there is a limit of 65535 characters to the lengths, which do not have to be
+the same, as this example demonstrates. This is the only kind of lookbehind
+supported by PCRE2 versions earlier than 10.43 and by the alternative matching
+function pcre2_dfa_match().
+

+

+In PCRE2 10.43 and later, pcre2_match() supports lookbehind assertions in
+which one or more top-level alternatives can match more than one string length,
+for example
+
+  (?<=colou?r)
+

+The maximum matching length for any branch of the lookbehind is limited to a
+value set by the calling program (default 255 characters). Unlimited repetition
+(for example \d*) is not supported. In some cases, the escape sequence \K
+(see above)
+can be used instead of a lookbehind assertion at the start of a pattern to get
+round the length limit restriction.
+

+

+In UTF-8 and UTF-16 modes, PCRE2 does not allow the \C escape (which matches a
+single code unit even in a UTF mode) to appear in lookbehind assertions,
+because it makes it impossible to calculate the length of the lookbehind. The
+\X and \R escapes, which can match different numbers of code units, are never
+permitted in lookbehinds.
+

+

+"Subroutine"
+calls (see below) such as (?2) or (?&X) are permitted in lookbehinds, as long
+as the called capture group matches a limited-length string. However,
+recursion,
+that is, a "subroutine" call into a group that is already active,
+is not supported.
+

+

+PCRE2 supports backreferences in lookbehinds, but only if certain conditions
+are met. The PCRE2_MATCH_UNSET_BACKREF option must not be set, there must be no
+use of (?| in the pattern (it creates duplicate group numbers), and if the
+backreference is by name, the name must be unique. Of course, the referenced
+group must itself match a limited length substring. The following pattern
+matches words containing at least two characters that begin and end with the
+same character:
+
+   \b(\w)\w++(?<=\1)
+

+

+

+Possessive quantifiers can be used in conjunction with lookbehind assertions to
+specify efficient matching at the end of subject strings. Consider a simple
+pattern such as
+
+  abcd$
+

+when applied to a long string that does not match. Because matching proceeds
+from left to right, PCRE2 will look for each "a" in the subject and then see if
+what follows matches the rest of the pattern. If the pattern is specified as
+
+  ^.*abcd$
+

+the initial .* matches the entire string at first, but when this fails (because
+there is no following "a"), it backtracks to match all but the last character,
+then all but the last two characters, and so on. Once again the search for "a"
+covers the entire string, from right to left, so we are no better off. However,
+if the pattern is written as
+
+  ^.*+(?<=abcd)
+

+there can be no backtracking for the .*+ item because of the possessive
+quantifier; it can match only the entire string. The subsequent lookbehind
+assertion does a single test on the last four characters. If it fails, the
+match fails immediately. For long strings, this approach makes a significant
+difference to the processing time.
+

+

+Using multiple assertions
+

+

+Several assertions (of any sort) may occur in succession. For example,
+
+  (?<=\d{3})(?<!999)foo
+

+matches "foo" preceded by three digits that are not "999". Notice that each of
+the assertions is applied independently at the same point in the subject
+string. First there is a check that the previous three characters are all
+digits, and then there is a check that the same three characters are not "999".
+This pattern does not match "foo" preceded by six characters, the first
+of which are digits and the last three of which are not "999". For example, it
+doesn't match "123abcfoo". A pattern to do that is
+
+  (?<=\d{3}...)(?<!999)foo
+

+This time the first assertion looks at the preceding six characters, checking
+that the first three are digits, and then the second assertion checks that the
+preceding three characters are not "999".
+

+

+Assertions can be nested in any combination. For example,
+
+  (?<=(?<!foo)bar)baz
+

+matches an occurrence of "baz" that is preceded by "bar" which in turn is not
+preceded by "foo", while
+
+  (?<=\d{3}(?!999)...)foo
+

+is another pattern that matches "foo" preceded by three digits and any three
+characters that are not "999".
+

+
NON-ATOMIC ASSERTIONS

+

+Traditional lookaround assertions are atomic. That is, if an assertion is true,
+but there is a subsequent matching failure, there is no backtracking into the
+assertion. However, there are some cases where non-atomic positive assertions
+can be useful. PCRE2 provides these using the following syntax:
+
+  (*non_atomic_positive_lookahead:  or (*napla: or (?*
+  (*non_atomic_positive_lookbehind: or (*naplb: or (?<*
+

+Consider the problem of finding the right-most word in a string that also
+appears earlier in the string, that is, it must appear at least twice in total.
+This pattern returns the required result as captured substring 1:
+
+  ^(?x)(*napla: .* \b(\w++)) (?> .*? \b\1\b ){2}
+

+For a subject such as "word1 word2 word3 word2 word3 word4" the result is
+"word3". How does it work? At the start, ^(?x) anchors the pattern and sets the
+"x" option, which causes white space (introduced for readability) to be
+ignored. Inside the assertion, the greedy .* at first consumes the entire
+string, but then has to backtrack until the rest of the assertion can match a
+word, which is captured by group 1. In other words, when the assertion first
+succeeds, it captures the right-most word in the string.
+

+

+The current matching point is then reset to the start of the subject, and the
+rest of the pattern match checks for two occurrences of the captured word,
+using an ungreedy .*? to scan from the left. If this succeeds, we are done, but
+if the last word in the string does not occur twice, this part of the pattern
+fails. If a traditional atomic lookahead (?= or (*pla: had been used, the
+assertion could not be re-entered, and the whole match would fail. The pattern
+would succeed only if the very last word in the subject was found twice.
+

+

+Using a non-atomic lookahead, however, means that when the last word does not
+occur twice in the string, the lookahead can backtrack and find the second-last
+word, and so on, until either the match succeeds, or all words have been
+tested.
+

+

+Two conditions must be met for a non-atomic assertion to be useful: the
+contents of one or more capturing groups must change after a backtrack into the
+assertion, and there must be a backreference to a changed group later in the
+pattern. If this is not the case, the rest of the pattern match fails exactly
+as before because nothing has changed, so using a non-atomic assertion just
+wastes resources.
+

+

+There is one exception to backtracking into a non-atomic assertion. If an
+(*ACCEPT) control verb is triggered, the assertion succeeds atomically. That
+is, a subsequent match failure cannot backtrack into the assertion.
+

+

+Non-atomic assertions are not supported by the alternative matching function
+pcre2_dfa_match(). They are supported by JIT, but only if they do not
+contain any control verbs such as (*ACCEPT). (This may change in future). Note
+that assertions that appear as conditions for
+conditional groups
+(see below) must be atomic.
+

+
SCRIPT RUNS

+

+In concept, a script run is a sequence of characters that are all from the same
+Unicode script such as Latin or Greek. However, because some scripts are
+commonly used together, and because some diacritical and other marks are used
+with multiple scripts, it is not that simple. There is a full description of
+the rules that PCRE2 uses in the section entitled
+"Script Runs"
+in the
+pcre2unicode
+documentation.
+

+

+If part of a pattern is enclosed between (*script_run: or (*sr: and a closing
+parenthesis, it fails if the sequence of characters that it matches are not a
+script run. After a failure, normal backtracking occurs. Script runs can be
+used to detect spoofing attacks using characters that look the same, but are
+from different scripts. The string "paypal.com" is an infamous example, where
+the letters could be a mixture of Latin and Cyrillic. This pattern ensures that
+the matched characters in a sequence of non-spaces that follow white space are
+a script run:
+
+  \s+(*sr:\S+)
+

+To be sure that they are all from the Latin script (for example), a lookahead
+can be used:
+
+  \s+(?=\p{Latin})(*sr:\S+)
+

+This works as long as the first character is expected to be a character in that
+script, and not (for example) punctuation, which is allowed with any script. If
+this is not the case, a more creative lookahead is needed. For example, if
+digits, underscore, and dots are permitted at the start:
+
+  \s+(?=[0-9_.]*\p{Latin})(*sr:\S+)
+
+

+

+

+In many cases, backtracking into a script run pattern fragment is not
+desirable. The script run can employ an atomic group to prevent this. Because
+this is a common requirement, a shorthand notation is provided by
+(*atomic_script_run: or (*asr:
+
+  (*asr:...) is the same as (*sr:(?>...))
+

+Note that the atomic group is inside the script run. Putting it outside would
+not prevent backtracking into the script run pattern.
+

+

+Support for script runs is not available if PCRE2 is compiled without Unicode
+support. A compile-time error is given if any of the above constructs is
+encountered. Script runs are not supported by the alternate matching function,
+pcre2_dfa_match() because they use the same mechanism as capturing
+parentheses.
+

+

+Warning: The (*ACCEPT) control verb
+(see below)
+should not be used within a script run group, because it causes an immediate
+exit from the group, bypassing the script run checking.
+

+
CONDITIONAL GROUPS

+

+It is possible to cause the matching process to obey a pattern fragment
+conditionally or to choose between two alternative fragments, depending on
+the result of an assertion, or whether a specific capture group has
+already been matched. The two possible forms of conditional group are:
+
+  (?(condition)yes-pattern)
+  (?(condition)yes-pattern|no-pattern)
+

+If the condition is satisfied, the yes-pattern is used; otherwise the
+no-pattern (if present) is used. An absent no-pattern is equivalent to an empty
+string (it always matches). If there are more than two alternatives in the
+group, a compile-time error occurs. Each of the two alternatives may itself
+contain nested groups of any form, including conditional groups; the
+restriction to two alternatives applies only at the level of the condition
+itself. This pattern fragment is an example where the alternatives are complex:
+
+  (?(1) (A|B|C) | (D | (?(2)E|F) | E) )
+
+

+

+

+There are five kinds of condition: references to capture groups, references to
+recursion, two pseudo-conditions called DEFINE and VERSION, and assertions.
+

+

+Checking for a used capture group by number
+

+

+If the text between the parentheses consists of a sequence of digits, the
+condition is true if a capture group of that number has previously matched. If
+there is more than one capture group with the same number (see the earlier
+section about duplicate group numbers),
+the condition is true if any of them have matched. An alternative notation,
+which is a PCRE2 extension, not supported by Perl, is to precede the digits
+with a plus or minus sign. In this case, the group number is relative rather
+than absolute. The most recently opened capture group (which could be enclosing
+this condition) can be referenced by (?(-1), the next most recent by (?(-2),
+and so on. Inside loops it can also make sense to refer to subsequent groups.
+The next capture group to be opened can be referenced as (?(+1), and so on. The
+value zero in any of these forms is not used; it provokes a compile-time error.
+

+

+Consider the following pattern, which contains non-significant white space to
+make it more readable (assume the PCRE2_EXTENDED option) and to divide it into
+three parts for ease of discussion:
+
+  ( \( )?    [^()]+    (?(1) \) )
+

+The first part matches an optional opening parenthesis, and if that
+character is present, sets it as the first captured substring. The second part
+matches one or more characters that are not parentheses. The third part is a
+conditional group that tests whether or not the first capture group
+matched. If it did, that is, if subject started with an opening parenthesis,
+the condition is true, and so the yes-pattern is executed and a closing
+parenthesis is required. Otherwise, since no-pattern is not present, the
+conditional group matches nothing. In other words, this pattern matches a
+sequence of non-parentheses, optionally enclosed in parentheses.
+

+

+If you were embedding this pattern in a larger one, you could use a relative
+reference:
+
+  ...other stuff... ( \( )?    [^()]+    (?(-1) \) ) ...
+

+This makes the fragment independent of the parentheses in the larger pattern.
+

+

+Checking for a used capture group by name
+

+

+Perl uses the syntax (?(<name>)...) or (?('name')...) to test for a used
+capture group by name. For compatibility with earlier versions of PCRE1, which
+had this facility before Perl, the syntax (?(name)...) is also recognized.
+Note, however, that undelimited names consisting of the letter R followed by
+digits are ambiguous (see the following section). Rewriting the above example
+to use a named group gives this:
+
+  (?<OPEN> \( )?    [^()]+    (?(<OPEN>) \) )
+

+If the name used in a condition of this kind is a duplicate, the test is
+applied to all groups of the same name, and is true if any one of them has
+matched.
+

+

+Checking for pattern recursion
+

+

+"Recursion" in this sense refers to any subroutine-like call from one part of
+the pattern to another, whether or not it is actually recursive. See the
+sections entitled
+"Recursive patterns"
+and
+"Groups as subroutines"
+below for details of recursion and subroutine calls.
+

+

+If a condition is the string (R), and there is no capture group with the name
+R, the condition is true if matching is currently in a recursion or subroutine
+call to the whole pattern or any capture group. If digits follow the letter R,
+and there is no group with that name, the condition is true if the most recent
+call is into a group with the given number, which must exist somewhere in the
+overall pattern. This is a contrived example that is equivalent to a+b:
+
+  ((?(R1)a+|(?1)b))
+

+However, in both cases, if there is a capture group with a matching name, the
+condition tests for its being set, as described in the section above, instead
+of testing for recursion. For example, creating a group with the name R1 by
+adding (?<R1>) to the above pattern completely changes its meaning.
+

+

+If a name preceded by ampersand follows the letter R, for example:
+
+  (?(R&name)...)
+

+the condition is true if the most recent recursion is into a group of that name
+(which must exist within the pattern).
+

+

+This condition does not check the entire recursion stack. It tests only the
+current level. If the name used in a condition of this kind is a duplicate, the
+test is applied to all groups of the same name, and is true if any one of
+them is the most recent recursion.
+

+

+At "top level", all these recursion test conditions are false.
+

+

+Defining capture groups for use by reference only
+

+

+If the condition is the string (DEFINE), the condition is always false, even if
+there is a group with the name DEFINE. In this case, there may be only one
+alternative in the rest of the conditional group. It is always skipped if
+control reaches this point in the pattern; the idea of DEFINE is that it can be
+used to define subroutines that can be referenced from elsewhere. (The use of
+subroutines
+is described below.) For example, a pattern to match an IPv4 address such as
+"192.168.23.245" could be written like this (ignore white space and line
+breaks):
+
+  (?(DEFINE) (?<byte> 2[0-4]\d | 25[0-5] | 1\d\d | [1-9]?\d) )
+  \b (?&byte) (\.(?&byte)){3} \b
+

+The first part of the pattern is a DEFINE group inside which another group
+named "byte" is defined. This matches an individual component of an IPv4
+address (a number less than 256). When matching takes place, this part of the
+pattern is skipped because DEFINE acts like a false condition. The rest of the
+pattern uses references to the named group to match the four dot-separated
+components of an IPv4 address, insisting on a word boundary at each end.
+

+

+Checking the PCRE2 version
+

+

+Programs that link with a PCRE2 library can check the version by calling
+pcre2_config() with appropriate arguments. Users of applications that do
+not have access to the underlying code cannot do this. A special "condition"
+called VERSION exists to allow such users to discover which version of PCRE2
+they are dealing with by using this condition to match a string such as
+"yesno". VERSION must be followed either by "=" or ">=" and a version number.
+For example:
+
+  (?(VERSION>=10.4)yes|no)
+

+This pattern matches "yes" if the PCRE2 version is greater or equal to 10.4, or
+"no" otherwise. The fractional part of the version number may not contain more
+than two digits.
+

+

+Assertion conditions
+

+

+If the condition is not in any of the above formats, it must be a parenthesized
+assertion. This may be a positive or negative lookahead or lookbehind
+assertion. However, it must be a traditional atomic assertion, not one of the
+non-atomic assertions.
+

+

+Consider this pattern, again containing non-significant white space, and with
+the two alternatives on the second line:
+
+  (?(?=[^a-z]*[a-z])
+  \d{2}-[a-z]{3}-\d{2}  |  \d{2}-\d{2}-\d{2} )
+

+The condition is a positive lookahead assertion that matches an optional
+sequence of non-letters followed by a letter. In other words, it tests for the
+presence of at least one letter in the subject. If a letter is found, the
+subject is matched against the first alternative; otherwise it is matched
+against the second. This pattern matches strings in one of the two forms
+dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits.
+

+

+When an assertion that is a condition contains capture groups, any
+capturing that occurs in a matching branch is retained afterwards, for both
+positive and negative assertions, because matching always continues after the
+assertion, whether it succeeds or fails. (Compare non-conditional assertions,
+for which captures are retained only for positive assertions that succeed.)
+

+
COMMENTS

+

+There are two ways of including comments in patterns that are processed by
+PCRE2. In both cases, the start of the comment must not be in a character
+class, nor in the middle of any other sequence of related characters such as
+(?: or a group name or number. The characters that make up a comment play
+no part in the pattern matching.
+

+

+The sequence (?# marks the start of a comment that continues up to the next
+closing parenthesis. Nested parentheses are not permitted. If the
+PCRE2_EXTENDED or PCRE2_EXTENDED_MORE option is set, an unescaped # character
+also introduces a comment, which in this case continues to immediately after
+the next newline character or character sequence in the pattern. Which
+characters are interpreted as newlines is controlled by an option passed to the
+compiling function or by a special sequence at the start of the pattern, as
+described in the section entitled
+"Newline conventions"
+above. Note that the end of this type of comment is a literal newline sequence
+in the pattern; escape sequences that happen to represent a newline do not
+count. For example, consider this pattern when PCRE2_EXTENDED is set, and the
+default newline convention (a single linefeed character) is in force:
+
+  abc #comment \n still comment
+

+On encountering the # character, pcre2_compile() skips along, looking for
+a newline in the pattern. The sequence \n is still literal at this stage, so
+it does not terminate the comment. Only an actual character with the code value
+0x0a (the default newline) does so.
+

+
RECURSIVE PATTERNS

+

+Consider the problem of matching a string in parentheses, allowing for
+unlimited nested parentheses. Without the use of recursion, the best that can
+be done is to use a pattern that matches up to some fixed depth of nesting. It
+is not possible to handle an arbitrary nesting depth.
+

+

+For some time, Perl has provided a facility that allows regular expressions to
+recurse (amongst other things). It does this by interpolating Perl code in the
+expression at run time, and the code can refer to the expression itself. A Perl
+pattern using code interpolation to solve the parentheses problem can be
+created like this:
+
+  $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;
+

+The (?p{...}) item interpolates Perl code at run time, and in this case refers
+recursively to the pattern in which it appears.
+

+

+Obviously, PCRE2 cannot support the interpolation of Perl code. Instead, it
+supports special syntax for recursion of the entire pattern, and also for
+individual capture group recursion. After its introduction in PCRE1 and Python,
+this kind of recursion was subsequently introduced into Perl at release 5.10.
+

+

+A special item that consists of (? followed by a number greater than zero and a
+closing parenthesis is a recursive subroutine call of the capture group of the
+given number, provided that it occurs inside that group. (If not, it is a
+non-recursive subroutine
+call, which is described in the next section.) The special item (?R) or (?0) is
+a recursive call of the entire regular expression.
+

+

+This PCRE2 pattern solves the nested parentheses problem (assume the
+PCRE2_EXTENDED option is set so that white space is ignored):
+
+  \( ( [^()]++ | (?R) )* \)
+

+First it matches an opening parenthesis. Then it matches any number of
+substrings which can either be a sequence of non-parentheses, or a recursive
+match of the pattern itself (that is, a correctly parenthesized substring).
+Finally there is a closing parenthesis. Note the use of a possessive quantifier
+to avoid backtracking into sequences of non-parentheses.
+

+

+If this were part of a larger pattern, you would not want to recurse the entire
+pattern, so instead you could use this:
+
+  ( \( ( [^()]++ | (?1) )* \) )
+

+We have put the pattern into parentheses, and caused the recursion to refer to
+them instead of the whole pattern.
+

+

+In a larger pattern, keeping track of parenthesis numbers can be tricky. This
+is made easier by the use of relative references. Instead of (?1) in the
+pattern above you can write (?-2) to refer to the second most recently opened
+parentheses preceding the recursion. In other words, a negative number counts
+capturing parentheses leftwards from the point at which it is encountered.
+

+

+Be aware however, that if
+duplicate capture group numbers
+are in use, relative references refer to the earliest group with the
+appropriate number. Consider, for example:
+
+  (?|(a)|(b)) (c) (?-2)
+

+The first two capture groups (a) and (b) are both numbered 1, and group (c)
+is number 2. When the reference (?-2) is encountered, the second most recently
+opened parentheses has the number 1, but it is the first such group (the (a)
+group) to which the recursion refers. This would be the same if an absolute
+reference (?1) was used. In other words, relative references are just a
+shorthand for computing a group number.
+

+

+It is also possible to refer to subsequent capture groups, by writing
+references such as (?+2). However, these cannot be recursive because the
+reference is not inside the parentheses that are referenced. They are always
+non-recursive subroutine
+calls, as described in the next section.
+

+

+An alternative approach is to use named parentheses. The Perl syntax for this
+is (?&name); PCRE1's earlier syntax (?P>name) is also supported. We could
+rewrite the above example as follows:
+
+  (?<pn> \( ( [^()]++ | (?&pn) )* \) )
+

+If there is more than one group with the same name, the earliest one is
+used.
+

+

+The example pattern that we have been looking at contains nested unlimited
+repeats, and so the use of a possessive quantifier for matching strings of
+non-parentheses is important when applying the pattern to strings that do not
+match. For example, when this pattern is applied to
+
+  (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+

+it yields "no match" quickly. However, if a possessive quantifier is not used,
+the match runs for a very long time indeed because there are so many different
+ways the + and * repeats can carve up the subject, and all have to be tested
+before failure can be reported.
+

+

+At the end of a match, the values of capturing parentheses are those from
+the outermost level. If you want to obtain intermediate values, a callout
+function can be used (see below and the
+pcre2callout
+documentation). If the pattern above is matched against
+
+  (ab(cd)ef)
+

+the value for the inner capturing parentheses (numbered 2) is "ef", which is
+the last value taken on at the top level. If a capture group is not matched at
+the top level, its final captured value is unset, even if it was (temporarily)
+set at a deeper level during the matching process.
+

+

+Do not confuse the (?R) item with the condition (R), which tests for recursion.
+Consider this pattern, which matches text in angle brackets, allowing for
+arbitrary nesting. Only digits are allowed in nested brackets (that is, when
+recursing), whereas any characters are permitted at the outer level.
+
+  < (?: (?(R) \d++  | [^<>]*+) | (?R)) * >
+

+In this pattern, (?(R) is the start of a conditional group, with two different
+alternatives for the recursive and non-recursive cases. The (?R) item is the
+actual recursive call.
+

+

+Differences in recursion processing between PCRE2 and Perl
+

+

+Some former differences between PCRE2 and Perl no longer exist.
+

+

+Before release 10.30, recursion processing in PCRE2 differed from Perl in that
+a recursive subroutine call was always treated as an atomic group. That is,
+once it had matched some of the subject string, it was never re-entered, even
+if it contained untried alternatives and there was a subsequent matching
+failure. (Historical note: PCRE implemented recursion before Perl did.)
+

+

+Starting with release 10.30, recursive subroutine calls are no longer treated
+as atomic. That is, they can be re-entered to try unused alternatives if there
+is a matching failure later in the pattern. This is now compatible with the way
+Perl works. If you want a subroutine call to be atomic, you must explicitly
+enclose it in an atomic group.
+

+

+Supporting backtracking into recursions simplifies certain types of recursive
+pattern. For example, this pattern matches palindromic strings:
+
+  ^((.)(?1)\2|.?)$
+

+The second branch in the group matches a single central character in the
+palindrome when there are an odd number of characters, or nothing when there
+are an even number of characters, but in order to work it has to be able to try
+the second case when the rest of the pattern match fails. If you want to match
+typical palindromic phrases, the pattern has to ignore all non-word characters,
+which can be done like this:
+
+  ^\W*+((.)\W*+(?1)\W*+\2|\W*+.?)\W*+$
+

+If run with the PCRE2_CASELESS option, this pattern matches phrases such as "A
+man, a plan, a canal: Panama!". Note the use of the possessive quantifier *+ to
+avoid backtracking into sequences of non-word characters. Without this, PCRE2
+takes a great deal longer (ten times or more) to match typical phrases, and
+Perl takes so long that you think it has gone into a loop.
+

+

+Another way in which PCRE2 and Perl used to differ in their recursion
+processing is in the handling of captured values. Formerly in Perl, when a
+group was called recursively or as a subroutine (see the next section), it
+had no access to any values that were captured outside the recursion, whereas
+in PCRE2 these values can be referenced. Consider this pattern:
+
+  ^(.)(\1|a(?2))
+

+This pattern matches "bab". The first capturing parentheses match "b", then in
+the second group, when the backreference \1 fails to match "b", the second
+alternative matches "a" and then recurses. In the recursion, \1 does now match
+"b" and so the whole match succeeds. This match used to fail in Perl, but in
+later versions (I tried 5.024) it now works.
+

+
GROUPS AS SUBROUTINES

+

+If the syntax for a recursive group call (either by number or by name) is used
+outside the parentheses to which it refers, it operates a bit like a subroutine
+in a programming language. More accurately, PCRE2 treats the referenced group
+as an independent subpattern which it tries to match at the current matching
+position. The called group may be defined before or after the reference. A
+numbered reference can be absolute or relative, as in these examples:
+
+  (...(absolute)...)...(?2)...
+  (...(relative)...)...(?-1)...
+  (...(?+1)...(relative)...
+

+An earlier example pointed out that the pattern
+
+  (sens|respons)e and \1ibility
+

+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If instead the pattern
+
+  (sens|respons)e and (?1)ibility
+

+is used, it does match "sense and responsibility" as well as the other two
+strings. Another example is given in the discussion of DEFINE above.
+

+

+Like recursions, subroutine calls used to be treated as atomic, but this
+changed at PCRE2 release 10.30, so backtracking into subroutine calls can now
+occur. However, any capturing parentheses that are set during the subroutine
+call revert to their previous values afterwards.
+

+

+Processing options such as case-independence are fixed when a group is
+defined, so if it is used as a subroutine, such options cannot be changed for
+different calls. For example, consider this pattern:
+
+  (abc)(?i:(?-1))
+

+It matches "abcabc". It does not match "abcABC" because the change of
+processing option does not affect the called group.
+

+

+The behaviour of
+backtracking control verbs
+in groups when called as subroutines is described in the section entitled
+"Backtracking verbs in subroutines"
+below.
+

+
ONIGURUMA SUBROUTINE SYNTAX

+

+For compatibility with Oniguruma, the non-Perl syntax \g followed by a name or
+a number enclosed either in angle brackets or single quotes, is an alternative
+syntax for calling a group as a subroutine, possibly recursively. Here are two
+of the examples used above, rewritten using this syntax:
+
+  (?<pn> \( ( (?>[^()]+) | \g<pn> )* \) )
+  (sens|respons)e and \g'1'ibility
+

+PCRE2 supports an extension to Oniguruma: if a number is preceded by a
+plus or a minus sign it is taken as a relative reference. For example:
+
+  (abc)(?i:\g<-1>)
+

+Note that \g{...} (Perl syntax) and \g<...> (Oniguruma syntax) are not
+synonymous. The former is a backreference; the latter is a subroutine call.
+

+
CALLOUTS

+

+Perl has a feature whereby using the sequence (?{...}) causes arbitrary Perl
+code to be obeyed in the middle of matching a regular expression. This makes it
+possible, amongst other things, to extract different substrings that match the
+same pair of parentheses when there is a repetition.
+

+

+PCRE2 provides a similar feature, but of course it cannot obey arbitrary Perl
+code. The feature is called "callout". The caller of PCRE2 provides an external
+function by putting its entry point in a match context using the function
+pcre2_set_callout(), and then passing that context to pcre2_match()
+or pcre2_dfa_match(). If no match context is passed, or if the callout
+entry point is set to NULL, callouts are disabled.
+

+

+Within a regular expression, (?C<arg>) indicates a point at which the external
+function is to be called. There are two kinds of callout: those with a
+numerical argument and those with a string argument. (?C) on its own with no
+argument is treated as (?C0). A numerical argument allows the application to
+distinguish between different callouts. String arguments were added for release
+10.20 to make it possible for script languages that use PCRE2 to embed short
+scripts within patterns in a similar way to Perl.
+

+

+During matching, when PCRE2 reaches a callout point, the external function is
+called. It is provided with the number or string argument of the callout, the
+position in the pattern, and one item of data that is also set in the match
+block. The callout function may cause matching to proceed, to backtrack, or to
+fail.
+

+

+By default, PCRE2 implements a number of optimizations at matching time, and
+one side-effect is that sometimes callouts are skipped. If you need all
+possible callouts to happen, you need to set options that disable the relevant
+optimizations. More details, including a complete description of the
+programming interface to the callout function, are given in the
+pcre2callout
+documentation.
+

+

+Callouts with numerical arguments
+

+

+If you just want to have a means of identifying different callout points, put a
+number less than 256 after the letter C. For example, this pattern has two
+callout points:
+
+  (?C1)abc(?C2)def
+

+If the PCRE2_AUTO_CALLOUT flag is passed to pcre2_compile(), numerical
+callouts are automatically installed before each item in the pattern. They are
+all numbered 255. If there is a conditional group in the pattern whose
+condition is an assertion, an additional callout is inserted just before the
+condition. An explicit callout may also be set at this position, as in this
+example:
+
+  (?(?C9)(?=a)abc|def)
+

+Note that this applies only to assertion conditions, not to other types of
+condition.
+

+

+Callouts with string arguments
+

+

+A delimited string may be used instead of a number as a callout argument. The
+starting delimiter must be one of ` ' " ^ % # $ { and the ending delimiter is
+the same as the start, except for {, where the ending delimiter is }. If the
+ending delimiter is needed within the string, it must be doubled. For
+example:
+
+  (?C'ab ''c'' d')xyz(?C{any text})pqr
+

+The doubling is removed before the string is passed to the callout function.
+

+
BACKTRACKING CONTROL

+

+There are a number of special "Backtracking Control Verbs" (to use Perl's
+terminology) that modify the behaviour of backtracking during matching. They
+are generally of the form (*VERB) or (*VERB:NAME). Some verbs take either form,
+and may behave differently depending on whether or not a name argument is
+present. The names are not required to be unique within the pattern.
+

+

+By default, for compatibility with Perl, a name is any sequence of characters
+that does not include a closing parenthesis. The name is not processed in
+any way, and it is not possible to include a closing parenthesis in the name.
+This can be changed by setting the PCRE2_ALT_VERBNAMES option, but the result
+is no longer Perl-compatible.
+

+

+When PCRE2_ALT_VERBNAMES is set, backslash processing is applied to verb names
+and only an unescaped closing parenthesis terminates the name. However, the
+only backslash items that are permitted are \Q, \E, and sequences such as
+\x{100} that define character code points. Character type escapes such as \d
+are faulted.
+

+

+A closing parenthesis can be included in a name either as \) or between \Q
+and \E. In addition to backslash processing, if the PCRE2_EXTENDED or
+PCRE2_EXTENDED_MORE option is also set, unescaped whitespace in verb names is
+skipped, and #-comments are recognized, exactly as in the rest of the pattern.
+PCRE2_EXTENDED and PCRE2_EXTENDED_MORE do not affect verb names unless
+PCRE2_ALT_VERBNAMES is also set.
+

+

+The maximum length of a name is 255 in the 8-bit library and 65535 in the
+16-bit and 32-bit libraries. If the name is empty, that is, if the closing
+parenthesis immediately follows the colon, the effect is as if the colon were
+not there. Any number of these verbs may occur in a pattern. Except for
+(*ACCEPT), they may not be quantified.
+

+

+Since these verbs are specifically related to backtracking, most of them can be
+used only when the pattern is to be matched using the traditional matching
+function, because that uses a backtracking algorithm. With the exception of
+(*FAIL), which behaves like a failing negative assertion, the backtracking
+control verbs cause an error if encountered by the DFA matching function.
+

+

+The behaviour of these verbs in
+repeated groups,
+assertions,
+and in
+capture groups called as subroutines
+(whether or not recursively) is documented below.
+

+

+Optimizations that affect backtracking verbs
+

+

+PCRE2 contains some optimizations that are used to speed up matching by running
+some checks at the start of each match attempt. For example, it may know the
+minimum length of matching subject, or that a particular character must be
+present. When one of these optimizations bypasses the running of a match, any
+included backtracking verbs will not, of course, be processed. You can suppress
+the start-of-match optimizations by setting the PCRE2_NO_START_OPTIMIZE option
+when calling pcre2_compile(), or by starting the pattern with
+(*NO_START_OPT). There is more discussion of this option in the section
+entitled
+"Compiling a pattern"
+in the
+pcre2api
+documentation.
+

+

+Experiments with Perl suggest that it too has similar optimizations, and like
+PCRE2, turning them off can change the result of a match.
+

+

+Verbs that act immediately
+

+

+The following verbs act as soon as they are encountered.
+
+   (*ACCEPT) or (*ACCEPT:NAME)
+

+This verb causes the match to end successfully, skipping the remainder of the
+pattern. However, when it is inside a capture group that is called as a
+subroutine, only that group is ended successfully. Matching then continues
+at the outer level. If (*ACCEPT) in triggered in a positive assertion, the
+assertion succeeds; in a negative assertion, the assertion fails.
+

+

+If (*ACCEPT) is inside capturing parentheses, the data so far is captured. For
+example:
+
+  A((?:A|B(*ACCEPT)|C)D)
+

+This matches "AB", "AAD", or "ACD"; when it matches "AB", "B" is captured by
+the outer parentheses.
+

+

+(*ACCEPT) is the only backtracking verb that is allowed to be quantified
+because an ungreedy quantification with a minimum of zero acts only when a
+backtrack happens. Consider, for example,
+
+  (A(*ACCEPT)??B)C
+

+where A, B, and C may be complex expressions. After matching "A", the matcher
+processes "BC"; if that fails, causing a backtrack, (*ACCEPT) is triggered and
+the match succeeds. In both cases, all but C is captured. Whereas (*COMMIT)
+(see below) means "fail on backtrack", a repeated (*ACCEPT) of this type means
+"succeed on backtrack".
+

+

+Warning: (*ACCEPT) should not be used within a script run group, because
+it causes an immediate exit from the group, bypassing the script run checking.
+
+  (*FAIL) or (*FAIL:NAME)
+

+This verb causes a matching failure, forcing backtracking to occur. It may be
+abbreviated to (*F). It is equivalent to (?!) but easier to read. The Perl
+documentation notes that it is probably useful only when combined with (?{}) or
+(??{}). Those are, of course, Perl features that are not present in PCRE2. The
+nearest equivalent is the callout feature, as for example in this pattern:
+
+  a+(?C)(*FAIL)
+

+A match with the string "aaaa" always fails, but the callout is taken before
+each backtrack happens (in this example, 10 times).
+

+

+(*ACCEPT:NAME) and (*FAIL:NAME) behave the same as (*MARK:NAME)(*ACCEPT) and
+(*MARK:NAME)(*FAIL), respectively, that is, a (*MARK) is recorded just before
+the verb acts.
+

+

+Recording which path was taken
+

+

+There is one verb whose main purpose is to track how a match was arrived at,
+though it also has a secondary use in conjunction with advancing the match
+starting point (see (*SKIP) below).
+
+  (*MARK:NAME) or (*:NAME)
+

+A name is always required with this verb. For all the other backtracking
+control verbs, a NAME argument is optional.
+

+

+When a match succeeds, the name of the last-encountered mark name on the
+matching path is passed back to the caller as described in the section entitled
+"Other information about the match"
+in the
+pcre2api
+documentation. This applies to all instances of (*MARK) and other verbs,
+including those inside assertions and atomic groups. However, there are
+differences in those cases when (*MARK) is used in conjunction with (*SKIP) as
+described below.
+

+

+The mark name that was last encountered on the matching path is passed back. A
+verb without a NAME argument is ignored for this purpose. Here is an example of
+pcre2test output, where the "mark" modifier requests the retrieval and
+outputting of (*MARK) data:
+
+    re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+  data> XY
+   0: XY
+  MK: A
+  XZ
+   0: XZ
+  MK: B
+

+The (*MARK) name is tagged with "MK:" in this output, and in this example it
+indicates which of the two alternatives matched. This is a more efficient way
+of obtaining this information than putting each alternative in its own
+capturing parentheses.
+

+

+If a verb with a name is encountered in a positive assertion that is true, the
+name is recorded and passed back if it is the last-encountered. This does not
+happen for negative assertions or failing positive assertions.
+

+

+After a partial match or a failed match, the last encountered name in the
+entire match process is returned. For example:
+
+    re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+  data> XP
+  No match, mark = B
+

+Note that in this unanchored example the mark is retained from the match
+attempt that started at the letter "X" in the subject. Subsequent match
+attempts starting at "P" and then with an empty string do not get as far as the
+(*MARK) item, but nevertheless do not reset it.
+

+

+If you are interested in (*MARK) values after failed matches, you should
+probably set the PCRE2_NO_START_OPTIMIZE option
+(see above)
+to ensure that the match is always attempted.
+

+

+Verbs that act after backtracking
+

+

+The following verbs do nothing when they are encountered. Matching continues
+with what follows, but if there is a subsequent match failure, causing a
+backtrack to the verb, a failure is forced. That is, backtracking cannot pass
+to the left of the verb. However, when one of these verbs appears inside an
+atomic group or in a lookaround assertion that is true, its effect is confined
+to that group, because once the group has been matched, there is never any
+backtracking into it. Backtracking from beyond an assertion or an atomic group
+ignores the entire group, and seeks a preceding backtracking point.
+

+

+These verbs differ in exactly what kind of failure occurs when backtracking
+reaches them. The behaviour described below is what happens when the verb is
+not in a subroutine or an assertion. Subsequent sections cover these special
+cases.
+
+  (*COMMIT) or (*COMMIT:NAME)
+

+This verb causes the whole match to fail outright if there is a later matching
+failure that causes backtracking to reach it. Even if the pattern is
+unanchored, no further attempts to find a match by advancing the starting point
+take place. If (*COMMIT) is the only backtracking verb that is encountered,
+once it has been passed pcre2_match() is committed to finding a match at
+the current starting point, or not at all. For example:
+
+  a+(*COMMIT)b
+

+This matches "xxaab" but not "aacaab". It can be thought of as a kind of
+dynamic anchor, or "I've started, so I must finish."
+

+

+The behaviour of (*COMMIT:NAME) is not the same as (*MARK:NAME)(*COMMIT). It is
+like (*MARK:NAME) in that the name is remembered for passing back to the
+caller. However, (*SKIP:NAME) searches only for names that are set with
+(*MARK), ignoring those set by any of the other backtracking verbs.
+

+

+If there is more than one backtracking verb in a pattern, a different one that
+follows (*COMMIT) may be triggered first, so merely passing (*COMMIT) during a
+match does not always guarantee that a match must be at this starting point.
+

+

+Note that (*COMMIT) at the start of a pattern is not the same as an anchor,
+unless PCRE2's start-of-match optimizations are turned off, as shown in this
+output from pcre2test:
+
+    re> /(*COMMIT)abc/
+  data> xyzabc
+   0: abc
+  data>
+  re> /(*COMMIT)abc/no_start_optimize
+  data> xyzabc
+  No match
+

+For the first pattern, PCRE2 knows that any match must start with "a", so the
+optimization skips along the subject to "a" before applying the pattern to the
+first set of data. The match attempt then succeeds. The second pattern disables
+the optimization that skips along to the first character. The pattern is now
+applied starting at "x", and so the (*COMMIT) causes the match to fail without
+trying any other starting points.
+
+  (*PRUNE) or (*PRUNE:NAME)
+

+This verb causes the match to fail at the current starting position in the
+subject if there is a later matching failure that causes backtracking to reach
+it. If the pattern is unanchored, the normal "bumpalong" advance to the next
+starting character then happens. Backtracking can occur as usual to the left of
+(*PRUNE), before it is reached, or when matching to the right of (*PRUNE), but
+if there is no match to the right, backtracking cannot cross (*PRUNE). In
+simple cases, the use of (*PRUNE) is just an alternative to an atomic group or
+possessive quantifier, but there are some uses of (*PRUNE) that cannot be
+expressed in any other way. In an anchored pattern (*PRUNE) has the same effect
+as (*COMMIT).
+

+

+The behaviour of (*PRUNE:NAME) is not the same as (*MARK:NAME)(*PRUNE). It is
+like (*MARK:NAME) in that the name is remembered for passing back to the
+caller. However, (*SKIP:NAME) searches only for names set with (*MARK),
+ignoring those set by other backtracking verbs.
+
+  (*SKIP)
+

+This verb, when given without a name, is like (*PRUNE), except that if the
+pattern is unanchored, the "bumpalong" advance is not to the next character,
+but to the position in the subject where (*SKIP) was encountered. (*SKIP)
+signifies that whatever text was matched leading up to it cannot be part of a
+successful match if there is a later mismatch. Consider:
+
+  a+(*SKIP)b
+

+If the subject is "aaaac...", after the first match attempt fails (starting at
+the first character in the string), the starting point skips on to start the
+next attempt at "c". Note that a possessive quantifier does not have the same
+effect as this example; although it would suppress backtracking during the
+first match attempt, the second attempt would start at the second character
+instead of skipping on to "c".
+

+

+If (*SKIP) is used to specify a new starting position that is the same as the
+starting position of the current match, or (by being inside a lookbehind)
+earlier, the position specified by (*SKIP) is ignored, and instead the normal
+"bumpalong" occurs.
+
+  (*SKIP:NAME)
+

+When (*SKIP) has an associated name, its behaviour is modified. When such a
+(*SKIP) is triggered, the previous path through the pattern is searched for the
+most recent (*MARK) that has the same name. If one is found, the "bumpalong"
+advance is to the subject position that corresponds to that (*MARK) instead of
+to where (*SKIP) was encountered. If no (*MARK) with a matching name is found,
+the (*SKIP) is ignored.
+

+

+The search for a (*MARK) name uses the normal backtracking mechanism, which
+means that it does not see (*MARK) settings that are inside atomic groups or
+assertions, because they are never re-entered by backtracking. Compare the
+following pcre2test examples:
+
+    re> /a(?>(*MARK:X))(*SKIP:X)(*F)|(.)/
+  data: abc
+   0: a
+   1: a
+  data:
+    re> /a(?:(*MARK:X))(*SKIP:X)(*F)|(.)/
+  data: abc
+   0: b
+   1: b
+

+In the first example, the (*MARK) setting is in an atomic group, so it is not
+seen when (*SKIP:X) triggers, causing the (*SKIP) to be ignored. This allows
+the second branch of the pattern to be tried at the first character position.
+In the second example, the (*MARK) setting is not in an atomic group. This
+allows (*SKIP:X) to find the (*MARK) when it backtracks, and this causes a new
+matching attempt to start at the second character. This time, the (*MARK) is
+never seen because "a" does not match "b", so the matcher immediately jumps to
+the second branch of the pattern.
+

+

+Note that (*SKIP:NAME) searches only for names set by (*MARK:NAME). It ignores
+names that are set by other backtracking verbs.
+
+  (*THEN) or (*THEN:NAME)
+

+This verb causes a skip to the next innermost alternative when backtracking
+reaches it. That is, it cancels any further backtracking within the current
+alternative. Its name comes from the observation that it can be used for a
+pattern-based if-then-else block:
+
+  ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+

+If the COND1 pattern matches, FOO is tried (and possibly further items after
+the end of the group if FOO succeeds); on failure, the matcher skips to the
+second alternative and tries COND2, without backtracking into COND1. If that
+succeeds and BAR fails, COND3 is tried. If subsequently BAZ fails, there are no
+more alternatives, so there is a backtrack to whatever came before the entire
+group. If (*THEN) is not inside an alternation, it acts like (*PRUNE).
+

+

+The behaviour of (*THEN:NAME) is not the same as (*MARK:NAME)(*THEN). It is
+like (*MARK:NAME) in that the name is remembered for passing back to the
+caller. However, (*SKIP:NAME) searches only for names set with (*MARK),
+ignoring those set by other backtracking verbs.
+

+

+A group that does not contain a | character is just a part of the enclosing
+alternative; it is not a nested alternation with only one alternative. The
+effect of (*THEN) extends beyond such a group to the enclosing alternative.
+Consider this pattern, where A, B, etc. are complex pattern fragments that do
+not contain any | characters at this level:
+
+  A (B(*THEN)C) | D
+

+If A and B are matched, but there is a failure in C, matching does not
+backtrack into A; instead it moves to the next alternative, that is, D.
+However, if the group containing (*THEN) is given an alternative, it
+behaves differently:
+
+  A (B(*THEN)C | (*FAIL)) | D
+

+The effect of (*THEN) is now confined to the inner group. After a failure in C,
+matching moves to (*FAIL), which causes the whole group to fail because there
+are no more alternatives to try. In this case, matching does backtrack into A.
+

+

+Note that a conditional group is not considered as having two alternatives,
+because only one is ever used. In other words, the | character in a conditional
+group has a different meaning. Ignoring white space, consider:
+
+  ^.*? (?(?=a) a | b(*THEN)c )
+

+If the subject is "ba", this pattern does not match. Because .*? is ungreedy,
+it initially matches zero characters. The condition (?=a) then fails, the
+character "b" is matched, but "c" is not. At this point, matching does not
+backtrack to .*? as might perhaps be expected from the presence of the |
+character. The conditional group is part of the single alternative that
+comprises the whole pattern, and so the match fails. (If there was a backtrack
+into .*?, allowing it to match "b", the match would succeed.)
+

+

+The verbs just described provide four different "strengths" of control when
+subsequent matching fails. (*THEN) is the weakest, carrying on the match at the
+next alternative. (*PRUNE) comes next, failing the match at the current
+starting position, but allowing an advance to the next character (for an
+unanchored pattern). (*SKIP) is similar, except that the advance may be more
+than one character. (*COMMIT) is the strongest, causing the entire match to
+fail.
+

+

+More than one backtracking verb
+

+

+If more than one backtracking verb is present in a pattern, the one that is
+backtracked onto first acts. For example, consider this pattern, where A, B,
+etc. are complex pattern fragments:
+
+  (A(*COMMIT)B(*THEN)C|ABD)
+

+If A matches but B fails, the backtrack to (*COMMIT) causes the entire match to
+fail. However, if A and B match, but C fails, the backtrack to (*THEN) causes
+the next alternative (ABD) to be tried. This behaviour is consistent, but is
+not always the same as Perl's. It means that if two or more backtracking verbs
+appear in succession, all but the last of them has no effect. Consider this
+example:
+
+  ...(*COMMIT)(*PRUNE)...
+

+If there is a matching failure to the right, backtracking onto (*PRUNE) causes
+it to be triggered, and its action is taken. There can never be a backtrack
+onto (*COMMIT).

+Backtracking verbs in repeated groups
+

+

+PCRE2 sometimes differs from Perl in its handling of backtracking verbs in
+repeated groups. For example, consider:
+
+  /(a(*COMMIT)b)+ac/
+

+If the subject is "abac", Perl matches unless its optimizations are disabled,
+but PCRE2 always fails because the (*COMMIT) in the second repeat of the group
+acts.
+

+

+Backtracking verbs in assertions
+

+

+(*FAIL) in any assertion has its normal effect: it forces an immediate
+backtrack. The behaviour of the other backtracking verbs depends on whether or
+not the assertion is standalone or acting as the condition in a conditional
+group.
+

+

+(*ACCEPT) in a standalone positive assertion causes the assertion to succeed
+without any further processing; captured strings and a mark name (if set) are
+retained. In a standalone negative assertion, (*ACCEPT) causes the assertion to
+fail without any further processing; captured substrings and any mark name are
+discarded.
+

+

+If the assertion is a condition, (*ACCEPT) causes the condition to be true for
+a positive assertion and false for a negative one; captured substrings are
+retained in both cases.
+

+

+The remaining verbs act only when a later failure causes a backtrack to
+reach them. This means that, for the Perl-compatible assertions, their effect
+is confined to the assertion, because Perl lookaround assertions are atomic. A
+backtrack that occurs after such an assertion is complete does not jump back
+into the assertion. Note in particular that a (*MARK) name that is set in an
+assertion is not "seen" by an instance of (*SKIP:NAME) later in the pattern.
+

+

+PCRE2 now supports non-atomic positive assertions, as described in the section
+entitled
+"Non-atomic assertions"
+above. These assertions must be standalone (not used as conditions). They are
+not Perl-compatible. For these assertions, a later backtrack does jump back
+into the assertion, and therefore verbs such as (*COMMIT) can be triggered by
+backtracks from later in the pattern.
+

+

+The effect of (*THEN) is not allowed to escape beyond an assertion. If there
+are no more branches to try, (*THEN) causes a positive assertion to be false,
+and a negative assertion to be true.
+

+

+The other backtracking verbs are not treated specially if they appear in a
+standalone positive assertion. In a conditional positive assertion,
+backtracking (from within the assertion) into (*COMMIT), (*SKIP), or (*PRUNE)
+causes the condition to be false. However, for both standalone and conditional
+negative assertions, backtracking into (*COMMIT), (*SKIP), or (*PRUNE) causes
+the assertion to be true, without considering any further alternative branches.
+

+

+Backtracking verbs in subroutines
+

+

+These behaviours occur whether or not the group is called recursively.
+

+

+(*ACCEPT) in a group called as a subroutine causes the subroutine match to
+succeed without any further processing. Matching then continues after the
+subroutine call. Perl documents this behaviour. Perl's treatment of the other
+verbs in subroutines is different in some cases.
+

+

+(*FAIL) in a group called as a subroutine has its normal effect: it forces
+an immediate backtrack.
+

+

+(*COMMIT), (*SKIP), and (*PRUNE) cause the subroutine match to fail when
+triggered by being backtracked to in a group called as a subroutine. There is
+then a backtrack at the outer level.
+

+

+(*THEN), when triggered, skips to the next alternative in the innermost
+enclosing group that has alternatives (its normal behaviour). However, if there
+is no such group within the subroutine's group, the subroutine match fails and
+there is a backtrack at the outer level.

+
PCRE2 PERFORMANCE

+

+Two aspects of performance are discussed below: memory usage and processing
+time. The way you express your pattern as a regular expression can affect both
+of them.
+

+
COMPILED PATTERN MEMORY USAGE

+

+Patterns are compiled by PCRE2 into a reasonably efficient interpretive code,
+so that most simple patterns do not use much memory for storing the compiled
+version. However, there is one case where the memory usage of a compiled
+pattern can be unexpectedly large. If a parenthesized group has a quantifier
+with a minimum greater than 1 and/or a limited maximum, the whole group is
+repeated in the compiled code. For example, the pattern
+
+  (abc|def){2,4}
+

+is compiled as if it were
+
+  (abc|def)(abc|def)((abc|def)(abc|def)?)?
+

+(Technical aside: It is done this way so that backtrack points within each of
+the repetitions can be independently maintained.)
+

+

+For regular expressions whose quantifiers use only small numbers, this is not
+usually a problem. However, if the numbers are large, and particularly if such
+repetitions are nested, the memory usage can become an embarrassment. For
+example, the very simple pattern
+
+  ((ab){1,1000}c){1,3}
+

+uses over 50KiB when compiled using the 8-bit library. When PCRE2 is
+compiled with its default internal pointer size of two bytes, the size limit on
+a compiled pattern is 65535 code units in the 8-bit and 16-bit libraries, and
+this is reached with the above pattern if the outer repetition is increased
+from 3 to 4. PCRE2 can be compiled to use larger internal pointers and thus
+handle larger compiled patterns, but it is better to try to rewrite your
+pattern to use less memory if you can.
+

+

+One way of reducing the memory usage for such patterns is to make use of
+PCRE2's
+"subroutine"
+facility. Re-writing the above pattern as
+
+  ((ab)(?2){0,999}c)(?1){0,2}
+

+reduces the memory requirements to around 16KiB, and indeed it remains under
+20KiB even with the outer repetition increased to 100. However, this kind of
+pattern is not always exactly equivalent, because any captures within
+subroutine calls are lost when the subroutine completes. If this is not a
+problem, this kind of rewriting will allow you to process patterns that PCRE2
+cannot otherwise handle. The matching performance of the two different versions
+of the pattern are roughly the same. (This applies from release 10.30 - things
+were different in earlier releases.)
+

+
STACK AND HEAP USAGE AT RUN TIME

+

+From release 10.30, the interpretive (non-JIT) version of pcre2_match()
+uses very little system stack at run time. In earlier releases recursive
+function calls could use a great deal of stack, and this could cause problems,
+but this usage has been eliminated. Backtracking positions are now explicitly
+remembered in memory frames controlled by the code.
+

+

+The size of each frame depends on the size of pointer variables and the number
+of capturing parenthesized groups in the pattern being matched. On a 64-bit
+system the frame size for a pattern with no captures is 128 bytes. For each
+capturing group the size increases by 16 bytes.
+

+

+Until release 10.41, an initial 20KiB frames vector was allocated on the system
+stack, but this still caused some issues for multi-thread applications where
+each thread has a very small stack. From release 10.41 backtracking memory
+frames are always held in heap memory. An initial heap allocation is obtained
+the first time any match data block is passed to pcre2_match(). This is
+remembered with the match data block and re-used if that block is used for
+another match. It is freed when the match data block itself is freed.
+

+

+The size of the initial block is the larger of 20KiB or ten times the pattern's
+frame size, unless the heap limit is less than this, in which case the heap
+limit is used. If the initial block proves to be too small during matching, it
+is replaced by a larger block, subject to the heap limit. The heap limit is
+checked only when a new block is to be allocated. Reducing the heap limit
+between calls to pcre2_match() with the same match data block does not
+affect the saved block.
+

+

+In contrast to pcre2_match(), pcre2_dfa_match() does use recursive
+function calls, but only for processing atomic groups, lookaround assertions,
+and recursion within the pattern. The original version of the code used to
+allocate quite large internal workspace vectors on the stack, which caused some
+problems for some patterns in environments with small stacks. From release
+10.32 the code for pcre2_dfa_match() has been re-factored to use heap
+memory when necessary for internal workspace when recursing, though recursive
+function calls are still used.
+

+

+The "match depth" parameter can be used to limit the depth of function
+recursion, and the "match heap" parameter to limit heap memory in
+pcre2_dfa_match().
+

+
PROCESSING TIME

+

+Certain items in regular expression patterns are processed more efficiently
+than others. It is more efficient to use a character class like [aeiou] than a
+set of single-character alternatives such as (a|e|i|o|u). In general, the
+simplest construction that provides the required behaviour is usually the most
+efficient. Jeffrey Friedl's book contains a lot of useful general discussion
+about optimizing regular expressions for efficient performance. This document
+contains a few observations about PCRE2.
+

+

+Using Unicode character properties (the \p, \P, and \X escapes) is slow,
+because PCRE2 has to use a multi-stage table lookup whenever it needs a
+character's property. If you can find an alternative pattern that does not use
+character properties, it will probably be faster.
+

+

+By default, the escape sequences \b, \d, \s, and \w, and the POSIX
+character classes such as [:alpha:] do not use Unicode properties, partly for
+backwards compatibility, and partly for performance reasons. However, you can
+set the PCRE2_UCP option or start the pattern with (*UCP) if you want Unicode
+character properties to be used. This can double the matching time for items
+such as \d, when matched with pcre2_match(); the performance loss is
+less with a DFA matching function, and in both cases there is not much
+difference for \b.
+

+

+When a pattern begins with .* not in atomic parentheses, nor in parentheses
+that are the subject of a backreference, and the PCRE2_DOTALL option is set,
+the pattern is implicitly anchored by PCRE2, since it can match only at the
+start of a subject string. If the pattern has multiple top-level branches, they
+must all be anchorable. The optimization can be disabled by the
+PCRE2_NO_DOTSTAR_ANCHOR option, and is automatically disabled if the pattern
+contains (*PRUNE) or (*SKIP).
+

+

+If PCRE2_DOTALL is not set, PCRE2 cannot make this optimization, because the
+dot metacharacter does not then match a newline, and if the subject string
+contains newlines, the pattern may match from the character immediately
+following one of them instead of from the very start. For example, the pattern
+
+  .*second
+

+matches the subject "first\nand second" (where \n stands for a newline
+character), with the match starting at the seventh character. In order to do
+this, PCRE2 has to retry the match starting after every newline in the subject.
+

+

+If you are using such a pattern with subject strings that do not contain
+newlines, the best performance is obtained by setting PCRE2_DOTALL, or starting
+the pattern with ^.* or ^.*? to indicate explicit anchoring. That saves PCRE2
+from having to scan along the subject looking for a newline to restart at.
+

+

+Beware of patterns that contain nested indefinite repeats. These can take a
+long time to run when applied to a string that does not match. Consider the
+pattern fragment
+
+  ^(a+)*
+

+This can match "aaaa" in 16 different ways, and this number increases very
+rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4
+times, and for each of those cases other than 0 or 4, the + repeats can match
+different numbers of times.) When the remainder of the pattern is such that the
+entire match is going to fail, PCRE2 has in principle to try every possible
+variation, and this can take an extremely long time, even for relatively short
+strings.
+

+

+An optimization catches some of the more simple cases such as
+
+  (a+)*b
+

+where a literal character follows. Before embarking on the standard matching
+procedure, PCRE2 checks that there is a "b" later in the subject string, and if
+there is not, it fails the match immediately. However, when there is no
+following literal this optimization cannot be used. You can see the difference
+by comparing the behaviour of
+
+  (a+)*\d
+

+with the pattern above. The former gives a failure almost instantly when
+applied to a whole line of "a" characters, whereas the latter takes an
+appreciable time with strings longer than about 20 characters.
+

+

+In many cases, the solution to this kind of performance issue is to use an
+atomic group or a possessive quantifier. This can often reduce memory
+requirements as well. As another example, consider this pattern:
+
+  ([^<]|<(?!inet))+
+

+It matches from wherever it starts until it encounters "<inet" or the end of
+the data, and is the kind of pattern that might be used when processing an XML
+file. Each iteration of the outer parentheses matches either one character that
+is not "<" or a "<" that is not followed by "inet". However, each time a
+parenthesis is processed, a backtracking position is passed, so this
+formulation uses a memory frame for each matched character. For a long string,
+a lot of memory is required. Consider now this rewritten pattern, which matches
+exactly the same strings:
+
+  ([^<]++|<(?!inet))+
+

+This runs much faster, because sequences of characters that do not contain "<"
+are "swallowed" in one item inside the parentheses, and a possessive quantifier
+is used to stop any backtracking into the runs of non-"<" characters. This
+version also uses a lot less memory because entry to a new set of parentheses
+happens only when a "<" character that is not followed by "inet" is encountered
+(and we assume this is relatively rare).
+

+

+This example shows that one way of optimizing performance when matching long
+subject strings is to write repeated parenthesized subpatterns to match more
+than one character whenever possible.
+

+

+SETTING RESOURCE LIMITS
+

+

+You can set limits on the amount of processing that takes place when matching,
+and on the amount of heap memory that is used. The default values of the limits
+are very large, and unlikely ever to operate. They can be changed when PCRE2 is
+built, and they can also be set when pcre2_match() or
+pcre2_dfa_match() is called. For details of these interfaces, see the
+pcre2build
+documentation and the section entitled
+"The match context"
+in the
+pcre2api
+documentation.
+

+

+The pcre2test test program has a modifier called "find_limits" which, if
+applied to a subject line, causes it to find the smallest limits that allow a
+pattern to match. This is done by repeatedly matching with different limits.

DESCRIPTION

+

+This set of functions provides a POSIX-style API for the PCRE2 regular
+expression 8-bit library. There are no POSIX-style wrappers for PCRE2's 16-bit
+and 32-bit libraries. See the
+pcre2api
+documentation for a description of PCRE2's native API, which contains much
+additional functionality.
+

+

+IMPORTANT NOTE: The functions described here are NOT thread-safe, and
+should not be used in multi-threaded applications. They are also limited to
+processing subjects that are not bigger than 2GB. Use the native API instead.
+

+

+These functions are wrapper functions that ultimately call the PCRE2 native
+API. Their prototypes are defined in the pcre2posix.h header file, and
+they all have unique names starting with pcre2_. However, the
+pcre2posix.h header also contains macro definitions that convert the
+standard POSIX names such regcomp() into pcre2_regcomp() etc. This
+means that a program can use the usual POSIX names without running the risk of
+accidentally linking with POSIX functions from a different library.
+

+

+On Unix-like systems the PCRE2 POSIX library is called libpcre2-posix, so
+can be accessed by adding -lpcre2-posix to the command for linking an
+application. Because the POSIX functions call the native ones, it is also
+necessary to add -lpcre2-8.
+

+

+On Windows systems, if you are linking to a DLL version of the library, it is
+recommended that PCRE2POSIX_SHARED is defined before including the
+pcre2posix.h header, as it will allow for a more efficient way to
+invoke the functions by adding the __declspec(dllimport) decorator.
+

+

+Although they were not defined as prototypes in pcre2posix.h, releases
+10.33 to 10.36 of the library contained functions with the POSIX names
+regcomp() etc. These simply passed their arguments to the PCRE2
+functions. These functions were provided for backwards compatibility with
+earlier versions of PCRE2, which had only POSIX names. However, this has proved
+troublesome in situations where a program links with several libraries, some of
+which use PCRE2's POSIX interface while others use the real POSIX functions.
+For this reason, the POSIX names have been removed since release 10.37.
+

+

+Calling the header file pcre2posix.h avoids any conflict with other POSIX
+libraries. It can, of course, be renamed or aliased as regex.h, which is
+the "correct" name, if there is no clash. It provides two structure types,
+regex_t for compiled internal forms, and regmatch_t for returning
+captured substrings. It also defines some constants whose names start with
+"REG_"; these are used for setting options and identifying error codes.
+

+
USING THE POSIX FUNCTIONS

+

+Note that these functions are just POSIX-style wrappers for PCRE2's native API.
+They do not give POSIX regular expression behaviour, and they are not
+thread-safe or even POSIX compatible.
+

+

+Those POSIX option bits that can reasonably be mapped to PCRE2 native options
+have been implemented. In addition, the option REG_EXTENDED is defined with the
+value zero. This has no effect, but since programs that are written to the
+POSIX interface often use it, this makes it easier to slot in PCRE2 as a
+replacement library. Other POSIX options are not even defined.
+

+

+There are also some options that are not defined by POSIX. These have been
+added at the request of users who want to make use of certain PCRE2-specific
+features via the POSIX calling interface or to add BSD or GNU functionality.
+

+

+When PCRE2 is called via these functions, it is only the API that is POSIX-like
+in style. The syntax and semantics of the regular expressions themselves are
+still those of Perl, subject to the setting of various PCRE2 options, as
+described below. "POSIX-like in style" means that the API approximates to the
+POSIX definition; it is not fully POSIX-compatible, and in multi-unit encoding
+domains it is probably even less compatible.
+

+

+The descriptions below use the actual names of the functions, but, as described
+above, the standard POSIX names (without the pcre2_ prefix) may also be
+used.
+

+
COMPILING A PATTERN

+

+The function pcre2_regcomp() is called to compile a pattern into an
+internal form. By default, the pattern is a C string terminated by a binary
+zero (but see REG_PEND below). The preg argument is a pointer to a
+regex_t structure that is used as a base for storing information about
+the compiled regular expression. It is also used for input when REG_PEND is
+set. The regex_t structure used by pcre2_regcomp() is defined in
+pcre2posix.h and is not the same as the structure used by other libraries
+that provide POSIX-style matching.
+

+

+The argument cflags is either zero, or contains one or more of the bits
+defined by the following macros:
+
+  REG_DOTALL
+

+The PCRE2_DOTALL option is set when the regular expression is passed for
+compilation to the native function. Note that REG_DOTALL is not part of the
+POSIX standard.
+
+  REG_ICASE
+

+The PCRE2_CASELESS option is set when the regular expression is passed for
+compilation to the native function.
+
+  REG_NEWLINE
+

+The PCRE2_MULTILINE option is set when the regular expression is passed for
+compilation to the native function. Note that this does not mimic the
+defined POSIX behaviour for REG_NEWLINE (see the following section).
+
+  REG_NOSPEC
+

+The PCRE2_LITERAL option is set when the regular expression is passed for
+compilation to the native function. This disables all meta characters in the
+pattern, causing it to be treated as a literal string. The only other options
+that are allowed with REG_NOSPEC are REG_ICASE, REG_NOSUB, REG_PEND, and
+REG_UTF. Note that REG_NOSPEC is not part of the POSIX standard.
+
+  REG_NOSUB
+

+When a pattern that is compiled with this flag is passed to
+pcre2_regexec() for matching, the nmatch and pmatch arguments
+are ignored, and no captured strings are returned. Versions of the PCRE library
+prior to 10.22 used to set the PCRE2_NO_AUTO_CAPTURE compile option, but this
+no longer happens because it disables the use of backreferences.
+
+  REG_PEND
+

+If this option is set, the reg_endp field in the preg structure
+(which has the type const char *) must be set to point to the character beyond
+the end of the pattern before calling pcre2_regcomp(). The pattern itself
+may now contain binary zeros, which are treated as data characters. Without
+REG_PEND, a binary zero terminates the pattern and the re_endp field is
+ignored. This is a GNU extension to the POSIX standard and should be used with
+caution in software intended to be portable to other systems.
+
+  REG_UCP
+

+The PCRE2_UCP option is set when the regular expression is passed for
+compilation to the native function. This causes PCRE2 to use Unicode properties
+when matching \d, \w, etc., instead of just recognizing ASCII values. Note
+that REG_UCP is not part of the POSIX standard.
+
+  REG_UNGREEDY
+

+The PCRE2_UNGREEDY option is set when the regular expression is passed for
+compilation to the native function. Note that REG_UNGREEDY is not part of the
+POSIX standard.
+
+  REG_UTF
+

+The PCRE2_UTF option is set when the regular expression is passed for
+compilation to the native function. This causes the pattern itself and all data
+strings used for matching it to be treated as UTF-8 strings. Note that REG_UTF
+is not part of the POSIX standard.
+

+

+In the absence of these flags, no options are passed to the native function.
+This means that the regex is compiled with PCRE2 default semantics. In
+particular, the way it handles newline characters in the subject string is the
+Perl way, not the POSIX way. Note that setting PCRE2_MULTILINE has only
+some of the effects specified for REG_NEWLINE. It does not affect the way
+newlines are matched by the dot metacharacter (they are not) or by a negative
+class such as [^a] (they are).
+

+

+The yield of pcre2_regcomp() is zero on success, and non-zero otherwise.
+The preg structure is filled in on success, and one other member of the
+structure (as well as re_endp) is public: re_nsub contains the
+number of capturing subpatterns in the regular expression. Various error codes
+are defined in the header file.
+

+

+NOTE: If the yield of pcre2_regcomp() is non-zero, you must not attempt
+to use the contents of the preg structure. If, for example, you pass it
+to pcre2_regexec(), the result is undefined and your program is likely to
+crash.
+

+
MATCHING NEWLINE CHARACTERS

+

+This area is not simple, because POSIX and Perl take different views of things.
+It is not possible to get PCRE2 to obey POSIX semantics, but then PCRE2 was
+never intended to be a POSIX engine. The following table lists the different
+possibilities for matching newline characters in Perl and PCRE2:
+
+                          Default   Change with
+
+  . matches newline          no     PCRE2_DOTALL
+  newline matches [^a]       yes    not changeable
+  $ matches \n at end        yes    PCRE2_DOLLAR_ENDONLY
+  $ matches \n in middle     no     PCRE2_MULTILINE
+  ^ matches \n in middle     no     PCRE2_MULTILINE
+

+This is the equivalent table for a POSIX-compatible pattern matcher:
+
+                          Default   Change with
+
+  . matches newline          yes    REG_NEWLINE
+  newline matches [^a]       yes    REG_NEWLINE
+  $ matches \n at end        no     REG_NEWLINE
+  $ matches \n in middle     no     REG_NEWLINE
+  ^ matches \n in middle     no     REG_NEWLINE
+

+This behaviour is not what happens when PCRE2 is called via its POSIX
+API. By default, PCRE2's behaviour is the same as Perl's, except that there is
+no equivalent for PCRE2_DOLLAR_ENDONLY in Perl. In both PCRE2 and Perl, there
+is no way to stop newline from matching [^a].
+

+

+Default POSIX newline handling can be obtained by setting PCRE2_DOTALL and
+PCRE2_DOLLAR_ENDONLY when calling pcre2_compile() directly, but there is
+no way to make PCRE2 behave exactly as for the REG_NEWLINE action. When using
+the POSIX API, passing REG_NEWLINE to PCRE2's pcre2_regcomp() function
+causes PCRE2_MULTILINE to be passed to pcre2_compile(), and REG_DOTALL
+passes PCRE2_DOTALL. There is no way to pass PCRE2_DOLLAR_ENDONLY.
+

+
MATCHING A PATTERN

+

+The function pcre2_regexec() is called to match a compiled pattern
+preg against a given string, which is by default terminated by a
+zero byte (but see REG_STARTEND below), subject to the options in eflags.
+These can be:
+
+  REG_NOTBOL
+

+The PCRE2_NOTBOL option is set when calling the underlying PCRE2 matching
+function.
+
+  REG_NOTEMPTY
+

+The PCRE2_NOTEMPTY option is set when calling the underlying PCRE2 matching
+function. Note that REG_NOTEMPTY is not part of the POSIX standard. However,
+setting this option can give more POSIX-like behaviour in some situations.
+
+  REG_NOTEOL
+

+The PCRE2_NOTEOL option is set when calling the underlying PCRE2 matching
+function.
+
+  REG_STARTEND
+

+When this option is set, the subject string starts at string +
+pmatch[0].rm_so and ends at string + pmatch[0].rm_eo, which
+should point to the first character beyond the string. There may be binary
+zeros within the subject string, and indeed, using REG_STARTEND is the only
+way to pass a subject string that contains a binary zero.
+

+

+Whatever the value of pmatch[0].rm_so, the offsets of the matched string
+and any captured substrings are still given relative to the start of
+string itself. (Before PCRE2 release 10.30 these were given relative to
+string + pmatch[0].rm_so, but this differs from other
+implementations.)
+

+

+This is a BSD extension, compatible with but not specified by IEEE Standard
+1003.2 (POSIX.2), and should be used with caution in software intended to be
+portable to other systems. Note that a non-zero rm_so does not imply
+REG_NOTBOL; REG_STARTEND affects only the location and length of the string,
+not how it is matched. Setting REG_STARTEND and passing pmatch as NULL
+are mutually exclusive; the error REG_INVARG is returned.
+

+

+If the pattern was compiled with the REG_NOSUB flag, no data about any matched
+strings is returned. The nmatch and pmatch arguments of
+pcre2_regexec() are ignored (except possibly as input for REG_STARTEND).
+

+

+The value of nmatch may be zero, and the value pmatch may be NULL
+(unless REG_STARTEND is set); in both these cases no data about any matched
+strings is returned.
+

+

+Otherwise, the portion of the string that was matched, and also any captured
+substrings, are returned via the pmatch argument, which points to an
+array of nmatch structures of type regmatch_t, containing the
+members rm_so and rm_eo. These contain the byte offset to the first
+character of each substring and the offset to the first character after the end
+of each substring, respectively. The 0th element of the vector relates to the
+entire portion of string that was matched; subsequent elements relate to
+the capturing subpatterns of the regular expression. Unused entries in the
+array have both structure members set to -1.
+

+

+regmatch_t as well as the regoff_t typedef it uses are defined in
+pcre2posix.h and are not warranted to have the same size or layout as other
+similarly named types from other libraries that provide POSIX-style matching.
+

+

+A successful match yields a zero return; various error codes are defined in the
+header file, of which REG_NOMATCH is the "expected" failure code.
+

+
ERROR MESSAGES

+

+The pcre2_regerror() function maps a non-zero errorcode from either
+pcre2_regcomp() or pcre2_regexec() to a printable message. If
+preg is not NULL, the error should have arisen from the use of that
+structure. A message terminated by a binary zero is placed in errbuf. If
+the buffer is too short, only the first errbuf_size - 1 characters of the
+error message are used. The yield of the function is the size of buffer needed
+to hold the whole message, including the terminating zero. This value is
+greater than errbuf_size if the message was truncated.
+

+
MEMORY USAGE

+

+Compiling a regular expression causes memory to be allocated and associated
+with the preg structure. The function pcre2_regfree() frees all
+such memory, after which preg may no longer be used as a compiled
+expression.

+PCRE2 SAMPLE PROGRAM
+

+

+A simple, complete demonstration program to get you started with using PCRE2 is
+supplied in the file pcre2demo.c in the src directory in the PCRE2
+distribution. A listing of this program is given in the
+pcre2demo
+documentation. If you do not have a copy of the PCRE2 distribution, you can
+save this listing to re-create the contents of pcre2demo.c.
+

+

+The demonstration program compiles the regular expression that is its
+first argument, and matches it against the subject string in its second
+argument. No PCRE2 options are set, and default character tables are used. If
+matching succeeds, the program outputs the portion of the subject that matched,
+together with the contents of any captured substrings.
+

+

+If the -g option is given on the command line, the program then goes on to
+check for further matches of the same regular expression in the same subject
+string. The logic is a little bit tricky because of the possibility of matching
+an empty string. Comments in the code explain what is going on.
+

+

+The code in pcre2demo.c is an 8-bit program that uses the PCRE2 8-bit
+library. It handles strings and characters that are stored in 8-bit code units.
+By default, one character corresponds to one code unit, but if the pattern
+starts with "(*UTF)", both it and the subject are treated as UTF-8 strings,
+where characters may occupy multiple code units.
+

+

+If PCRE2 is installed in the standard include and library directories for your
+operating system, you should be able to compile the demonstration program using
+a command like this:
+
+  cc -o pcre2demo pcre2demo.c -lpcre2-8
+

+If PCRE2 is installed elsewhere, you may need to add additional options to the
+command line. For example, on a Unix-like system that has PCRE2 installed in
+/usr/local, you can compile the demonstration program using a command
+like this:
+
+  cc -o pcre2demo -I/usr/local/include pcre2demo.c -L/usr/local/lib -lpcre2-8
+

+Once you have built the demonstration program, you can run simple tests like
+this:
+
+  ./pcre2demo 'cat|dog' 'the cat sat on the mat'
+  ./pcre2demo -g 'cat|dog' 'the dog sat on the cat'
+

+Note that there is a much more comprehensive test program, called
+pcre2test,
+which supports many more facilities for testing regular expressions using all
+three PCRE2 libraries (8-bit, 16-bit, and 32-bit, though not all three need be
+installed). The
+pcre2demo
+program is provided as a relatively simple coding example.
+

+

+If you try to run
+pcre2demo
+when PCRE2 is not installed in the standard library directory, you may get an
+error like this on some operating systems (e.g. Solaris):
+
+  ld.so.1: pcre2demo: fatal: libpcre2-8.so.0: open failed: No such file or directory
+

+This is caused by the way shared library support works on those systems. You
+need to add
+
+  -R/usr/local/lib
+

+(for example) to the compile command to get round this problem.

SAVING AND RE-USING PRECOMPILED PCRE2 PATTERNS

+

+  pcre2_general_context *gcontext);

+

+

+int32_t pcre2_serialize_get_number_of_codes(const uint8_t *bytes);
+

+

+If you are running an application that uses a large number of regular
+expression patterns, it may be useful to store them in a precompiled form
+instead of having to compile them every time the application is run. However,
+if you are using the just-in-time optimization feature, it is not possible to
+save and reload the JIT data, because it is position-dependent. The host on
+which the patterns are reloaded must be running the same version of PCRE2, with
+the same code unit width, and must also have the same endianness, pointer width
+and PCRE2_SIZE type. For example, patterns compiled on a 32-bit system using
+PCRE2's 16-bit library cannot be reloaded on a 64-bit system, nor can they be
+reloaded using the 8-bit library.
+

+

+Note that "serialization" in PCRE2 does not convert compiled patterns to an
+abstract format like Java or .NET serialization. The serialized output is
+really just a bytecode dump, which is why it can only be reloaded in the same
+environment as the one that created it. Hence the restrictions mentioned above.
+Applications that are not statically linked with a fixed version of PCRE2 must
+be prepared to recompile patterns from their sources, in order to be immune to
+PCRE2 upgrades.
+

+
SECURITY CONCERNS

+

+The facility for saving and restoring compiled patterns is intended for use
+within individual applications. As such, the data supplied to
+pcre2_serialize_decode() is expected to be trusted data, not data from
+arbitrary external sources. There is only some simple consistency checking, not
+complete validation of what is being re-loaded. Corrupted data may cause
+undefined results. For example, if the length field of a pattern in the
+serialized data is corrupted, the deserializing code may read beyond the end of
+the byte stream that is passed to it.
+

+
SAVING COMPILED PATTERNS

+

+Before compiled patterns can be saved they must be serialized, which in PCRE2
+means converting the pattern to a stream of bytes. A single byte stream may
+contain any number of compiled patterns, but they must all use the same
+character tables. A single copy of the tables is included in the byte stream
+(its size is 1088 bytes). For more details of character tables, see the
+section on locale support
+in the
+pcre2api
+documentation.
+

+

+The function pcre2_serialize_encode() creates a serialized byte stream
+from a list of compiled patterns. Its first two arguments specify the list,
+being a pointer to a vector of pointers to compiled patterns, and the length of
+the vector. The third and fourth arguments point to variables which are set to
+point to the created byte stream and its length, respectively. The final
+argument is a pointer to a general context, which can be used to specify custom
+memory management functions. If this argument is NULL, malloc() is used
+to obtain memory for the byte stream. The yield of the function is the number
+of serialized patterns, or one of the following negative error codes:
+
+  PCRE2_ERROR_BADDATA      the number of patterns is zero or less
+  PCRE2_ERROR_BADMAGIC     mismatch of id bytes in one of the patterns
+  PCRE2_ERROR_NOMEMORY     memory allocation failed
+  PCRE2_ERROR_MIXEDTABLES  the patterns do not all use the same tables
+  PCRE2_ERROR_NULL         the 1st, 3rd, or 4th argument is NULL
+

+PCRE2_ERROR_BADMAGIC means either that a pattern's code has been corrupted, or
+that a slot in the vector does not point to a compiled pattern.
+

+

+Once a set of patterns has been serialized you can save the data in any
+appropriate manner. Here is sample code that compiles two patterns and writes
+them to a file. It assumes that the variable fd refers to a file that is
+open for output. The error checking that should be present in a real
+application has been omitted for simplicity.
+
+  int errorcode;
+  uint8_t *bytes;
+  PCRE2_SIZE erroroffset;
+  PCRE2_SIZE bytescount;
+  pcre2_code *list_of_codes[2];
+  list_of_codes[0] = pcre2_compile("first pattern",
+    PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+  list_of_codes[1] = pcre2_compile("second pattern",
+    PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+  errorcode = pcre2_serialize_encode(list_of_codes, 2, &bytes,
+    &bytescount, NULL);
+  errorcode = fwrite(bytes, 1, bytescount, fd);
+

+Note that the serialized data is binary data that may contain any of the 256
+possible byte values. On systems that make a distinction between binary and
+non-binary data, be sure that the file is opened for binary output.
+

+

+Serializing a set of patterns leaves the original data untouched, so they can
+still be used for matching. Their memory must eventually be freed in the usual
+way by calling pcre2_code_free(). When you have finished with the byte
+stream, it too must be freed by calling pcre2_serialize_free(). If this
+function is called with a NULL argument, it returns immediately without doing
+anything.
+

+
RE-USING PRECOMPILED PATTERNS

+

+In order to re-use a set of saved patterns you must first make the serialized
+byte stream available in main memory (for example, by reading from a file). The
+management of this memory block is up to the application. You can use the
+pcre2_serialize_get_number_of_codes() function to find out how many
+compiled patterns are in the serialized data without actually decoding the
+patterns:
+
+  uint8_t *bytes = <serialized data>;
+  int32_t number_of_codes = pcre2_serialize_get_number_of_codes(bytes);
+

+The pcre2_serialize_decode() function reads a byte stream and recreates
+the compiled patterns in new memory blocks, setting pointers to them in a
+vector. The first two arguments are a pointer to a suitable vector and its
+length, and the third argument points to a byte stream. The final argument is a
+pointer to a general context, which can be used to specify custom memory
+management functions for the decoded patterns. If this argument is NULL,
+malloc() and free() are used. After deserialization, the byte
+stream is no longer needed and can be discarded.
+
+  pcre2_code *list_of_codes[2];
+  uint8_t *bytes = <serialized data>;
+  int32_t number_of_codes =
+    pcre2_serialize_decode(list_of_codes, 2, bytes, NULL);
+

+If the vector is not large enough for all the patterns in the byte stream, it
+is filled with those that fit, and the remainder are ignored. The yield of the
+function is the number of decoded patterns, or one of the following negative
+error codes:
+
+  PCRE2_ERROR_BADDATA    second argument is zero or less
+  PCRE2_ERROR_BADMAGIC   mismatch of id bytes in the data
+  PCRE2_ERROR_BADMODE    mismatch of code unit size or PCRE2 version
+  PCRE2_ERROR_BADSERIALIZEDDATA  other sanity check failure
+  PCRE2_ERROR_MEMORY     memory allocation failed
+  PCRE2_ERROR_NULL       first or third argument is NULL
+

+PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled
+on a system with different endianness.
+

+

+Decoded patterns can be used for matching in the usual way, and must be freed
+by calling pcre2_code_free(). However, be aware that there is a potential
+race issue if you are using multiple patterns that were decoded from a single
+byte stream in a multithreaded application. A single copy of the character
+tables is used by all the decoded patterns and a reference count is used to
+arrange for its memory to be automatically freed when the last pattern is
+freed, but there is no locking on this reference count. Therefore, if you want
+to call pcre2_code_free() for these patterns in different threads, you
+must arrange your own locking, and ensure that pcre2_code_free() cannot
+be called by two threads at the same time.
+

+

+If a pattern was processed by pcre2_jit_compile() before being
+serialized, the JIT data is discarded and so is no longer available after a
+save/restore cycle. You can, however, process a restored pattern with
+pcre2_jit_compile() if you wish.

PCRE2 REGULAR EXPRESSION SYNTAX SUMMARY

+

+The full syntax and semantics of the regular expressions that are supported by
+PCRE2 are described in the
+pcre2pattern
+documentation. This document contains a quick-reference summary of the syntax.
+

+
QUOTING

+

+
+  \x         where x is non-alphanumeric is a literal x
+  \Q...\E    treat enclosed characters as literal
+

+Note that white space inside \Q...\E is always treated as literal, even if
+PCRE2_EXTENDED is set, causing most other white space to be ignored.
+

+
BRACED ITEMS

+

+With one exception, wherever brace characters { and } are required to enclose
+data for constructions such as \g{2} or \k{name}, space and/or horizontal tab
+characters that follow { or precede } are allowed and are ignored. In the case
+of quantifiers, they may also appear before or after the comma. The exception
+is \u{...} which is not Perl-compatible and is recognized only when
+PCRE2_EXTRA_ALT_BSUX is set. This is an ECMAScript compatibility feature, and
+follows ECMAScript's behaviour.
+

+
ESCAPED CHARACTERS

+

+This table applies to ASCII and Unicode environments. An unrecognized escape
+sequence causes an error.
+
+  \a         alarm, that is, the BEL character (hex 07)
+  \cx        "control-x", where x is a non-control ASCII character
+  \e         escape (hex 1B)
+  \f         form feed (hex 0C)
+  \n         newline (hex 0A)
+  \r         carriage return (hex 0D)
+  \t         tab (hex 09)
+  \0dd       character with octal code 0dd
+  \ddd       character with octal code ddd, or backreference
+  \o{ddd..}  character with octal code ddd..
+  \N{U+hh..} character with Unicode code point hh.. (Unicode mode only)
+  \xhh       character with hex code hh
+  \x{hh..}   character with hex code hh..
+

+If PCRE2_ALT_BSUX or PCRE2_EXTRA_ALT_BSUX is set ("ALT_BSUX mode"), the
+following are also recognized:
+
+  \U         the character "U"
+  \uhhhh     character with hex code hhhh
+  \u{hh..}   character with hex code hh.. but only for EXTRA_ALT_BSUX
+

+When \x is not followed by {, from zero to two hexadecimal digits are read,
+but in ALT_BSUX mode \x must be followed by two hexadecimal digits to be
+recognized as a hexadecimal escape; otherwise it matches a literal "x".
+Likewise, if \u (in ALT_BSUX mode) is not followed by four hexadecimal digits
+or (in EXTRA_ALT_BSUX mode) a sequence of hex digits in curly brackets, it
+matches a literal "u".
+

+

+Note that \0dd is always an octal code. The treatment of backslash followed by
+a non-zero digit is complicated; for details see the section
+"Non-printing characters"
+in the
+pcre2pattern
+documentation, where details of escape processing in EBCDIC environments are
+also given. \N{U+hh..} is synonymous with \x{hh..} in PCRE2 but is not
+supported in EBCDIC environments. Note that \N not followed by an opening
+curly bracket has a different meaning (see below).
+

+
CHARACTER TYPES

+

+
+  .          any character except newline;
+               in dotall mode, any character whatsoever
+  \C         one code unit, even in UTF mode (best avoided)
+  \d         a decimal digit
+  \D         a character that is not a decimal digit
+  \h         a horizontal white space character
+  \H         a character that is not a horizontal white space character
+  \N         a character that is not a newline
+  \p{xx}     a character with the xx property
+  \P{xx}     a character without the xx property
+  \R         a newline sequence
+  \s         a white space character
+  \S         a character that is not a white space character
+  \v         a vertical white space character
+  \V         a character that is not a vertical white space character
+  \w         a "word" character
+  \W         a "non-word" character
+  \X         a Unicode extended grapheme cluster
+

+\C is dangerous because it may leave the current matching point in the middle
+of a UTF-8 or UTF-16 character. The application can lock out the use of \C by
+setting the PCRE2_NEVER_BACKSLASH_C option. It is also possible to build PCRE2
+with the use of \C permanently disabled.
+

+

+By default, \d, \s, and \w match only ASCII characters, even in UTF-8 mode
+or in the 16-bit and 32-bit libraries. However, if locale-specific matching is
+happening, \s and \w may also match characters with code points in the range
+128-255. If the PCRE2_UCP option is set, the behaviour of these escape
+sequences is changed to use Unicode properties and they match many more
+characters, but there are some option settings that can restrict individual
+sequences to matching only ASCII characters.
+

+

+Property descriptions in \p and \P are matched caselessly; hyphens,
+underscores, and white space are ignored, in accordance with Unicode's "loose
+matching" rules.
+

+\p and \P, along with their abbreviations, by running this command:
+
+  pcre2test -LP
+

+

+
SCRIPT MATCHING WITH \p AND \P

+

+Many script names and their 4-letter abbreviations are recognized in
+\p{sc:...} or \p{scx:...} items, or on their own with \p (and also \P of
+course). You can obtain a list of these scripts by running this command:
+
+  pcre2test -LS
+

+

+
THE BIDI_CLASS PROPERTY FOR \p AND \P

+

+
+  \p{Bidi_Class:<class>}   matches a character with the given class
+  \p{BC:<class>}           matches a character with the given class

OPTION SETTING

+Changes of these options within a group are automatically cancelled at the end
+of the group.
+
+  (?a)            all ASCII options
+  (?aD)           restrict \d to ASCII in UCP mode

+  (?-...)         unset the given option(s)
+  (?^)            unset imnrsx options
+

+(?aP) implies (?aT) as well, though this has no additional effect. However, it
+means that (?-aP) is really (?-PT) which disables all ASCII restrictions for
+POSIX classes.
+

+

+Unsetting x or xx unsets both. Several options may be set at once, and a
+mixture of setting and unsetting such as (?i-x) is allowed, but there may be
+only one hyphen. Setting (but no unsetting) is allowed after (?^ for example
+(?^in). An option setting may appear at the start of a non-capture group, for
+example (?i:...).
+

+

+The following are recognized only at the very start of a pattern or after one
+of the newline or \R options with similar syntax. More than one of them may
+appear. For the first three, d is a decimal number.
+
+  (*LIMIT_DEPTH=d) set the backtracking limit to d
+  (*LIMIT_HEAP=d)  set the heap size limit to d * 1024 bytes
+  (*LIMIT_MATCH=d) set the match limit to d
+  (*NOTEMPTY)      set PCRE2_NOTEMPTY when matching
+  (*NOTEMPTY_ATSTART) set PCRE2_NOTEMPTY_ATSTART when matching
+  (*NO_AUTO_POSSESS) no auto-possessification (PCRE2_NO_AUTO_POSSESS)
+  (*NO_DOTSTAR_ANCHOR) no .* anchoring (PCRE2_NO_DOTSTAR_ANCHOR)
+  (*NO_JIT)       disable JIT optimization
+  (*NO_START_OPT) no start-match optimization (PCRE2_NO_START_OPTIMIZE)
+  (*UTF)          set appropriate UTF mode for the library in use
+  (*UCP)          set PCRE2_UCP (use Unicode properties for \d etc)
+

+Note that LIMIT_DEPTH, LIMIT_HEAP, and LIMIT_MATCH can only reduce the value of
+the limits set by the caller of pcre2_match() or pcre2_dfa_match(),
+not increase them. LIMIT_RECURSION is an obsolete synonym for LIMIT_DEPTH. The
+application can lock out the use of (*UTF) and (*UCP) by setting the
+PCRE2_NEVER_UTF or PCRE2_NEVER_UCP options, respectively, at compile time.

+
NEWLINE CONVENTION

+These are recognized only at the very start of the pattern or after option
+settings with a similar syntax.

+
BACKTRACKING CONTROL

+

+All backtracking control verbs may be in the form (*VERB:NAME). For (*MARK) the
+name is mandatory, for the others it is optional. (*SKIP) changes its behaviour
+if :NAME is present. The others just set a name for passing back to the caller,
+but this is not a name that (*SKIP) can see. The following act immediately they
+are reached:
+
+  (*ACCEPT)       force successful match
+  (*FAIL)         force backtrack; synonym (*F)
+  (*MARK:NAME)    set name to be passed back; synonym (*:NAME)
+

+The following act only when a subsequent match failure causes a backtrack to
+reach them. They all force a match failure, but they differ in what happens
+afterwards. Those that advance the start-of-match point do so only if the
+pattern is not anchored.
+
+  (*COMMIT)       overall failure, no advance of starting point
+  (*PRUNE)        advance to next starting character
+  (*SKIP)         advance to current matching position
+  (*SKIP:NAME)    advance to position corresponding to an earlier
+                  (*MARK:NAME); if not found, the (*SKIP) is ignored
+  (*THEN)         local failure, backtrack to next alternation
+

+The effect of one of these verbs in a group called as a subroutine is confined
+to the subroutine call.
+

+
CALLOUTS

+

+
+  (?C)            callout (assumed number 0)
+  (?Cn)           callout with numerical data n
+  (?C"text")      callout with string data
+

+The allowed string delimiters are ` ' " ^ % # $ (which are the same for the
+start and the end), and the starting delimiter { matched with the ending
+delimiter }. To encode the ending delimiter within the string, double it.

SYNOPSIS

+

+pcre2test [options] [input file [output file]]
+

+

+pcre2test is a test program for the PCRE2 regular expression libraries,
+but it can also be used for experimenting with regular expressions. This
+document describes the features of the test program; for details of the regular
+expressions themselves, see the
+pcre2pattern
+documentation. For details of the PCRE2 library function calls and their
+options, see the
+pcre2api
+documentation.
+

+

+The input for pcre2test is a sequence of regular expression patterns and
+subject strings to be matched. There are also command lines for setting
+defaults and controlling some special actions. The output shows the result of
+each match attempt. Modifiers on external or internal command lines, the
+patterns, and the subject lines specify PCRE2 function options, control how the
+subject is processed, and what output is produced.
+

+

+There are many obscure modifiers, some of which are specifically designed for
+use in conjunction with the test script and data files that are distributed as
+part of PCRE2. All the modifiers are documented here, some without much
+justification, but many of them are unlikely to be of use except when testing
+the libraries.
+

+
PCRE2's 8-BIT, 16-BIT AND 32-BIT LIBRARIES

+

+Different versions of the PCRE2 library can be built to support character
+strings that are encoded in 8-bit, 16-bit, or 32-bit code units. One, two, or
+all three of these libraries may be simultaneously installed. The
+pcre2test program can be used to test all the libraries. However, its own
+input and output are always in 8-bit format. When testing the 16-bit or 32-bit
+libraries, patterns and subject strings are converted to 16-bit or 32-bit
+format before being passed to the library functions. Results are converted back
+to 8-bit code units for output.
+

+

+In the rest of this document, the names of library functions and structures
+are given in generic form, for example, pcre2_compile(). The actual
+names used in the libraries have a suffix _8, _16, or _32, as appropriate.
+

+
INPUT ENCODING

+

+Input to pcre2test is processed line by line, either by calling the C
+library's fgets() function, or via the libreadline or libedit
+library. In some Windows environments character 26 (hex 1A) causes an immediate
+end of file, and no further data is read, so this character should be avoided
+unless you really want that action.
+

+

+The input is processed using C's string functions, so must not contain binary
+zeros, even though in Unix-like environments, fgets() treats any bytes
+other than newline as data characters. An error is generated if a binary zero
+is encountered. By default subject lines are processed for backslash escapes,
+which makes it possible to include any data value in strings that are passed to
+the library for matching. For patterns, there is a facility for specifying some
+or all of the 8-bit input characters as hexadecimal pairs, which makes it
+possible to include binary zeros.
+

+

+Input for the 16-bit and 32-bit libraries
+

+

+When testing the 16-bit or 32-bit libraries, there is a need to be able to
+generate character code points greater than 255 in the strings that are passed
+to the library. For subject lines, backslash escapes can be used. In addition,
+when the utf modifier (see
+"Setting compilation options"
+below) is set, the pattern and any following subject lines are interpreted as
+UTF-8 strings and translated to UTF-16 or UTF-32 as appropriate.
+

+

+For non-UTF testing of wide characters, the utf8_input modifier can be
+used. This is mutually exclusive with utf, and is allowed only in 16-bit
+or 32-bit mode. It causes the pattern and following subject lines to be treated
+as UTF-8 according to the original definition (RFC 2279), which allows for
+character values up to 0x7fffffff. Each character is placed in one 16-bit or
+32-bit code unit (in the 16-bit case, values greater than 0xffff cause an error
+to occur).
+

+

+UTF-8 (in its original definition) is not capable of encoding values greater
+than 0x7fffffff, but such values can be handled by the 32-bit library. When
+testing this library in non-UTF mode with utf8_input set, if any
+character is preceded by the byte 0xff (which is an invalid byte in UTF-8)
+0x80000000 is added to the character's value. This is the only way of passing
+such code points in a pattern string. For subject strings, using an escape
+sequence is preferable.
+

+
COMMAND LINE OPTIONS

+

+-8
+If the 8-bit library has been built, this option causes it to be used (this is
+the default). If the 8-bit library has not been built, this option causes an
+error.
+

+

+-16
+If the 16-bit library has been built, this option causes it to be used. If the
+8-bit library has not been built, this is the default. If the 16-bit library
+has not been built, this option causes an error.
+

+

+-32
+If the 32-bit library has been built, this option causes it to be used. If no
+other library has been built, this is the default. If the 32-bit library has
+not been built, this option causes an error.
+

+

+-ac
+Behave as if each pattern has the auto_callout modifier, that is, insert
+automatic callouts into every pattern that is compiled.
+

+

+-AC
+As for -ac, but in addition behave as if each subject line has the
+callout_extra modifier, that is, show additional information from
+callouts.
+

+

+-b
+Behave as if each pattern has the fullbincode modifier; the full
+internal binary form of the pattern is output after compilation.
+

+

+-C
+Output the version number of the PCRE2 library, and all available information
+about the optional features that are included, and then exit with zero exit
+code. All other options are ignored. If both -C and -LM are present, whichever
+is first is recognized.
+

+

+-C option
+Output information about a specific build-time option, then exit. This
+functionality is intended for use in scripts such as RunTest. The
+following options output the value and set the exit code as indicated:
+

+  unicode      Unicode support is available
+

+If an unknown option is given, an error message is output; the exit code is 0.
+

+

+-d
+Behave as if each pattern has the debug modifier; the internal
+form and information about the compiled pattern is output after compilation;
+-d is equivalent to -b -i.
+

+

+-dfa
+Behave as if each subject line has the dfa modifier; matching is done
+using the pcre2_dfa_match() function instead of the default
+pcre2_match().
+

+

+-error number[,number,...]
+Call pcre2_get_error_message() for each of the error numbers in the
+comma-separated list, display the resulting messages on the standard output,
+then exit with zero exit code. The numbers may be positive or negative. This is
+a convenience facility for PCRE2 maintainers.
+

+

+-help
+Output a brief summary these options and then exit.
+

+

+-i
+Behave as if each pattern has the info modifier; information about the
+compiled pattern is given after compilation.
+

+

+-jit
+Behave as if each pattern line has the jit modifier; after successful
+compilation, each pattern is passed to the just-in-time compiler, if available.
+

+

+-jitfast
+Behave as if each pattern line has the jitfast modifier; after
+successful compilation, each pattern is passed to the just-in-time compiler, if
+available, and each subject line is passed directly to the JIT matcher via its
+"fast path".
+

+

+-jitverify
+Behave as if each pattern line has the jitverify modifier; after

+

+

+-q
+Do not output the version number of pcre2test at the start of execution.
+

+

+-S size
+On Unix-like systems, set the size of the run-time stack to size

+-subject modifier-list
+Behave as if each subject line contains the given modifiers.
+

+

+-t
+Run each compile and match many times with a timer, and output the resulting
+times per compile or match. When JIT is used, separate times are given for the
+initial compile and the JIT compile. You can control the number of iterations
+that are used for timing by following -t with a number (as a separate
+item on the command line). For example, "-t 1000" iterates 1000 times. The
+default is to iterate 500,000 times.
+

+

+-tm
+This is like -t except that it times only the matching phase, not the
+compile phase.
+

+

+-T -TM
+These behave like -t and -tm, but in addition, at the end of a run,
+the total times for all compiles and matches are output.
+

+

+-version
+Output the PCRE2 version number and then exit.
+

+
DESCRIPTION

+

+If pcre2test is given two filename arguments, it reads from the first and
+writes to the second. If the first name is "-", input is taken from the
+standard input. If pcre2test is given only one argument, it reads from
+that file and writes to stdout. Otherwise, it reads from stdin and writes to
+stdout.
+

+

+When pcre2test is built, a configuration option can specify that it
+should be linked with the libreadline or libedit library. When this
+is done, if the input is from a terminal, it is read using the readline()
+function. This provides line-editing and history facilities. The output from
+the -help option states whether or not readline() will be used.
+

+

+The program handles any number of tests, each of which consists of a set of
+input lines. Each set starts with a regular expression pattern, followed by any
+number of subject lines to be matched against that pattern. In between sets of
+test data, command lines that begin with # may appear. This file format, with
+some restrictions, can also be processed by the perltest.sh script that
+is distributed with PCRE2 as a means of checking that the behaviour of PCRE2
+and Perl is the same. For a specification of perltest.sh, see the
+comments near its beginning. See also the #perltest command below.
+

+

+When the input is a terminal, pcre2test prompts for each line of input,
+using "re>" to prompt for regular expression patterns, and "data>" to prompt
+for subject lines. Command lines starting with # can be entered only in
+response to the "re>" prompt.
+

+

+Each subject line is matched separately and independently. If you want to do
+multi-line matches, you have to use the \n escape sequence (or \r or \r\n,
+etc., depending on the newline setting) in a single line of input to encode the
+newline sequences. There is no limit on the length of subject lines; the input
+buffer is automatically extended if it is too small. There are replication
+features that makes it possible to generate long repetitive pattern or subject
+lines without having to supply them explicitly.
+

+

+An empty line or the end of the file signals the end of the subject lines for a
+test, at which point a new pattern or command line is expected if there is
+still input to be read.
+

+
COMMAND LINES

+

+In between sets of test data, a line that begins with # is interpreted as a
+command line. If the first character is followed by white space or an
+exclamation mark, the line is treated as a comment, and ignored. Otherwise, the
+following commands are recognized:
+
+  #forbid_utf
+

+Subsequent patterns automatically have the PCRE2_NEVER_UTF and PCRE2_NEVER_UCP
+options set, which locks out the use of the PCRE2_UTF and PCRE2_UCP options and
+the use of (*UTF) and (*UCP) at the start of patterns. This command also forces
+an error if a subsequent pattern contains any occurrences of \P, \p, or \X,
+which are still supported when PCRE2_UTF is not set, but which require Unicode
+property support to be included in the library.
+

+

+This is a trigger guard that is used in test files to ensure that UTF or
+Unicode property tests are not accidentally added to files that are used when
+Unicode support is not included in the library. Setting PCRE2_NEVER_UTF and
+PCRE2_NEVER_UCP as a default can also be obtained by the use of #pattern;
+the difference is that #forbid_utf cannot be unset, and the automatic
+options are not displayed in pattern information, to avoid cluttering up test
+output.
+
+  #load <filename>
+

+This command is used to load a set of precompiled patterns from a file, as
+described in the section entitled "Saving and restoring compiled patterns"
+below.
+
+  #loadtables <filename>
+

+This command is used to load a set of binary character tables that can be
+accessed by the tables=3 qualifier. Such tables can be created by the
+pcre2_dftables program with the -b option.
+
+  #newline_default [<newline-list>]
+

+When PCRE2 is built, a default newline convention can be specified. This
+determines which characters and/or character pairs are recognized as indicating
+a newline in a pattern or subject string. The default can be overridden when a
+pattern is compiled. The standard test files contain tests of various newline
+conventions, but the majority of the tests expect a single linefeed to be
+recognized as a newline by default. Without special action the tests would fail
+when PCRE2 is compiled with either CR or CRLF as the default newline.
+

+

+The #newline_default command specifies a list of newline types that are
+acceptable as the default. The types must be one of CR, LF, CRLF, ANYCRLF,
+ANY, or NUL (in upper or lower case), for example:
+
+  #newline_default LF Any anyCRLF
+

+If the default newline is in the list, this command has no effect. Otherwise,
+except when testing the POSIX API, a newline modifier that specifies the
+first newline convention in the list (LF in the above example) is added to any
+pattern that does not already have a newline modifier. If the newline
+list is empty, the feature is turned off. This command is present in a number
+of the standard test input files.
+

+

+When the POSIX API is being tested there is no way to override the default
+newline convention, though it is possible to set the newline convention from
+within the pattern. A warning is given if the posix or posix_nosub
+modifier is used when #newline_default would set a default for the
+non-POSIX API.
+
+  #pattern <modifier-list>
+

+This command sets a default modifier list that applies to all subsequent
+patterns. Modifiers on a pattern can change these settings.
+
+  #perltest
+

+This line is used in test files that can also be processed by perltest.sh
+to confirm that Perl gives the same results as PCRE2. Subsequent tests are
+checked for the use of pcre2test features that are incompatible with the
+perltest.sh script.
+

+

+Patterns must use '/' as their delimiter, and only certain modifiers are
+supported. Comment lines, #pattern commands, and #subject commands that set or
+unset "mark" are recognized and acted on. The #perltest, #forbid_utf, and
+#newline_default commands, which are needed in the relevant pcre2test files,
+are silently ignored. All other command lines are ignored, but give a warning
+message. The #perltest command helps detect tests that are accidentally
+put in the wrong file or use the wrong delimiter. For more details of the
+perltest.sh script see the comments it contains.
+
+  #pop [<modifiers>]
+  #popcopy [<modifiers>]
+

+These commands are used to manipulate the stack of compiled patterns, as
+described in the section entitled "Saving and restoring compiled patterns"
+below.
+
+  #save <filename>
+

+This command is used to save a set of compiled patterns to a file, as described
+in the section entitled "Saving and restoring compiled patterns"
+below.
+
+  #subject <modifier-list>
+

+This command sets a default modifier list that applies to all subsequent
+subject lines. Modifiers on a subject line can change these settings.
+

+
MODIFIER SYNTAX

+

+Modifier lists are used with both pattern and subject lines. Items in a list
+are separated by commas followed by optional white space. Trailing whitespace
+in a modifier list is ignored. Some modifiers may be given for both patterns
+and subject lines, whereas others are valid only for one or the other. Each
+modifier has a long name, for example "anchored", and some of them must be
+followed by an equals sign and a value, for example, "offset=12". Values cannot
+contain comma characters, but may contain spaces. Modifiers that do not take
+values may be preceded by a minus sign to turn off a previous setting.
+

+

+A few of the more common modifiers can also be specified as single letters, for
+example "i" for "caseless". In documentation, following the Perl convention,
+these are written with a slash ("the /i modifier") for clarity. Abbreviated
+modifiers must all be concatenated in the first item of a modifier list. If the
+first item is not recognized as a long modifier name, it is interpreted as a
+sequence of these abbreviations. For example:
+
+  /abc/ig,newline=cr,jit=3
+

+This is a pattern line whose modifier list starts with two one-letter modifiers
+(/i and /g). The lower-case abbreviated modifiers are the same as used in Perl.
+

+
PATTERN SYNTAX

+

+A pattern line must start with one of the following characters (common symbols,
+excluding pattern meta-characters):
+
+  / ! " ' ` - = _ : ; , % & @ ~
+

+This is interpreted as the pattern's delimiter. A regular expression may be
+continued over several input lines, in which case the newline characters are
+included within it. It is possible to include the delimiter as a literal within
+the pattern by escaping it with a backslash, for example
+
+  /abc\/def/
+

+If you do this, the escape and the delimiter form part of the pattern, but
+since the delimiters are all non-alphanumeric, the inclusion of the backslash
+does not affect the pattern's interpretation. Note, however, that this trick
+does not work within \Q...\E literal bracketing because the backslash will
+itself be interpreted as a literal. If the terminating delimiter is immediately
+followed by a backslash, for example,
+
+  /abc/\
+

+a backslash is added to the end of the pattern. This is done to provide a way
+of testing the error condition that arises if a pattern finishes with a
+backslash, because
+
+  /abc\/
+

+is interpreted as the first line of a pattern that starts with "abc/", causing
+pcre2test to read the next line as a continuation of the regular expression.
+

+

+A pattern can be followed by a modifier list (details below).
+

+
SUBJECT LINE SYNTAX

+

+Before each subject line is passed to pcre2_match(),
+pcre2_dfa_match(), or pcre2_jit_match(), leading and trailing white
+space is removed, and the line is scanned for backslash escapes, unless the
+subject_literal modifier was set for the pattern. The following provide a
+means of encoding non-printing characters in a visible way:
+
+  \a         alarm (BEL, \x07)
+  \b         backspace (\x08)
+  \e         escape (\x27)
+  \f         form feed (\x0c)
+  \n         newline (\x0a)
+  \r         carriage return (\x0d)
+  \t         tab (\x09)
+  \v         vertical tab (\x0b)
+  \nnn       octal character (up to 3 octal digits); always
+               a byte unless > 255 in UTF-8 or 16-bit or 32-bit mode
+  \o{dd...}  octal character (any number of octal digits}
+  \xhh       hexadecimal byte (up to 2 hex digits)
+  \x{hh...}  hexadecimal character (any number of hex digits)
+

+The use of \x{hh...} is not dependent on the use of the utf modifier on
+the pattern. It is recognized always. There may be any number of hexadecimal
+digits inside the braces; invalid values provoke error messages.
+

+

+Note that \xhh specifies one byte rather than one character in UTF-8 mode;
+this makes it possible to construct invalid UTF-8 sequences for testing
+purposes. On the other hand, \x{hh} is interpreted as a UTF-8 character in
+UTF-8 mode, generating more than one byte if the value is greater than 127.
+When testing the 8-bit library not in UTF-8 mode, \x{hh} generates one byte
+for values less than 256, and causes an error for greater values.
+

+

+In UTF-16 mode, all 4-digit \x{hhhh} values are accepted. This makes it
+possible to construct invalid UTF-16 sequences for testing purposes.
+

+

+In UTF-32 mode, all 4- to 8-digit \x{...} values are accepted. This makes it
+possible to construct invalid UTF-32 sequences for testing purposes.
+

+

+There is a special backslash sequence that specifies replication of one or more
+characters:
+
+  \[<characters>]{<count>}
+

+This makes it possible to test long strings without having to provide them as
+part of the file. For example:
+
+  \[abc]{4}
+

+is converted to "abcabcabcabc". This feature does not support nesting. To
+include a closing square bracket in the characters, code it as \x5D.
+

+

+A backslash followed by an equals sign marks the end of the subject string and
+the start of a modifier list. For example:
+
+  abc\=notbol,notempty
+

+If the subject string is empty and \= is followed by whitespace, the line is
+treated as a comment line, and is not used for matching. For example:
+
+  \= This is a comment.
+  abc\= This is an invalid modifier list.
+

+A backslash followed by any other non-alphanumeric character just escapes that
+character. A backslash followed by anything else causes an error. However, if
+the very last character in the line is a backslash (and there is no modifier
+list), it is ignored. This gives a way of passing an empty line as data, since
+a real empty line terminates the data input.
+

+

+If the subject_literal modifier is set for a pattern, all subject lines
+that follow are treated as literals, with no special treatment of backslashes.
+No replication is possible, and any subject modifiers must be set as defaults
+by a #subject command.
+

+
PATTERN MODIFIERS

+

+There are several types of modifier that can appear in pattern lines. Except
+where noted below, they may also be used in #pattern commands. A
+pattern's modifier list can add to or override default modifiers that were set
+by a previous #pattern command.
+

+

+Setting compilation options
+

+

+The following modifiers set options for pcre2_compile(). Most of them set
+bits in the options argument of that function, but those whose names start with
+PCRE2_EXTRA are additional options that are set in the compile context.
+Some of these options have single-letter abbreviations. There is special
+handling for /x: if a second x is present, PCRE2_EXTENDED is converted into
+PCRE2_EXTENDED_MORE as in Perl. A third appearance adds PCRE2_EXTENDED as well,
+though this makes no difference to the way pcre2_compile() behaves. See
+pcre2api
+for a description of the effects of these options.

+      utf                       set PCRE2_UTF
+

+As well as turning on the PCRE2_UTF option, the utf modifier causes all
+non-printing characters in output strings to be printed using the \x{hh...}
+notation. Otherwise, those less than 0x100 are output in hex without the curly
+brackets. Setting utf in 16-bit or 32-bit mode also causes pattern and
+subject strings to be translated to UTF-16 or UTF-32, respectively, before
+being passed to library functions.
+

+

+Setting compilation controls
+

+

+The following modifiers affect the compilation process or request information
+about the pattern. There are single-letter abbreviations for some that are
+heavily used in the test files.

+      use_length                do not zero-terminate the pattern
+      utf8_input                treat input as UTF-8
+

+The effects of these modifiers are described in the following sections.
+

+

+Newline and \R handling
+

+

+The bsr modifier specifies what \R in a pattern should match. If it is
+set to "anycrlf", \R matches CR, LF, or CRLF only. If it is set to "unicode",
+\R matches any Unicode newline sequence. The default can be specified when
+PCRE2 is built; if it is not, the default is set to Unicode.
+

+

+The newline modifier specifies which characters are to be interpreted as
+newlines, both in the pattern and in subject lines. The type must be one of CR,
+LF, CRLF, ANYCRLF, ANY, or NUL (in upper or lower case).
+

+

+Information about a pattern
+

+

+The debug modifier is a shorthand for info,fullbincode, requesting
+all available information.
+

+

+The bincode modifier causes a representation of the compiled code to be
+output after compilation. This information does not contain length and offset
+values, which ensures that the same output is generated for different internal
+link sizes and different code unit widths. By using bincode, the same
+regression tests can be used in different environments.
+

+

+The fullbincode modifier, by contrast, does include length and
+offset values. This is used in a few special tests that run only for specific
+code unit widths and link sizes, and is also useful for one-off tests.
+

+

+The info modifier requests information about the compiled pattern
+(whether it is anchored, has a fixed first character, and so on). The
+information is obtained from the pcre2_pattern_info() function. Here are
+some typical examples:
+
+    re> /(?i)(^a|^b)/m,info
+  Capture group count = 1
+  Compile options: multiline
+  Overall options: caseless multiline
+  First code unit at start or follows newline
+  Subject length lower bound = 1
+
+    re> /(?i)abc/info
+  Capture group count = 0
+  Compile options: <none>
+  Overall options: caseless
+  First code unit = 'a' (caseless)
+  Last code unit = 'c' (caseless)
+  Subject length lower bound = 3
+

+"Compile options" are those specified by modifiers; "overall options" have
+added options that are taken or deduced from the pattern. If both sets of
+options are the same, just a single "options" line is output; if there are no
+options, the line is omitted. "First code unit" is where any match must start;
+if there is more than one they are listed as "starting code units". "Last code
+unit" is the last literal code unit that must be present in any match. This is
+not necessarily the last character. These lines are omitted if no starting or
+ending code units are recorded. The subject length line is omitted when
+no_start_optimize is set because the minimum length is not calculated
+when it can never be used.
+

+

+The framesize modifier shows the size, in bytes, of each storage frame
+used by pcre2_match() for handling backtracking. The size depends on the
+number of capturing parentheses in the pattern. A vector of these frames is
+used at matching time; its overall size is shown when the heaframes_size
+subject modifier is set.
+

+

+The callout_info modifier requests information about all the callouts in
+the pattern. A list of them is output at the end of any other information that
+is requested. For each callout, either its number or string is given, followed
+by the item that follows it in the pattern.
+

+

+Passing a NULL context
+

+

+Normally, pcre2test passes a context block to pcre2_compile(). If
+the null_context modifier is set, however, NULL is passed. This is for
+testing that pcre2_compile() behaves correctly in this case (it uses
+default values).
+

+

+Passing a NULL pattern
+

+

+The null_pattern modifier is for testing the behaviour of
+pcre2_compile() when the pattern argument is NULL. The length value
+passed is the default PCRE2_ZERO_TERMINATED unless use_length is set.
+Any length other than zero causes an error.
+

+

+Specifying pattern characters in hexadecimal
+

+

+The hex modifier specifies that the characters of the pattern, except for
+substrings enclosed in single or double quotes, are to be interpreted as pairs
+of hexadecimal digits. This feature is provided as a way of creating patterns
+that contain binary zeros and other non-printing characters. White space is
+permitted between pairs of digits. For example, this pattern contains three
+characters:
+
+  /ab 32 59/hex
+

+Parts of such a pattern are taken literally if quoted. This pattern contains
+nine characters, only two of which are specified in hexadecimal:
+
+  /ab "literal" 32/hex
+

+Either single or double quotes may be used. There is no way of including
+the delimiter within a substring. The hex and expand modifiers are
+mutually exclusive.
+

+

+Specifying the pattern's length
+

+

+By default, patterns are passed to the compiling functions as zero-terminated
+strings but can be passed by length instead of being zero-terminated. The
+use_length modifier causes this to happen. Using a length happens
+automatically (whether or not use_length is set) when hex is set,
+because patterns specified in hexadecimal may contain binary zeros.
+

+

+If hex or use_length is used with the POSIX wrapper API (see
+"Using the POSIX wrapper API"
+below), the REG_PEND extension is used to pass the pattern's length.
+

+

+Specifying a maximum for variable lookbehinds
+

+

+Variable lookbehind assertions are supported only if, for each one, there is a
+maximum length (in characters) that it can match. There is a limit on this,
+whose default can be set at build time, with an ultimate default of 255. The
+max_varlookbehind modifier uses the pcre2_set_max_varlookbehind()
+function to change the limit. Lookbehinds whose branches each match a fixed
+length are limited to 65535 characters per branch.
+

+

+Specifying wide characters in 16-bit and 32-bit modes
+

+

+In 16-bit and 32-bit modes, all input is automatically treated as UTF-8 and
+translated to UTF-16 or UTF-32 when the utf modifier is set. For testing
+the 16-bit and 32-bit libraries in non-UTF mode, the utf8_input modifier
+can be used. It is mutually exclusive with utf. Input lines are
+interpreted as UTF-8 as a means of specifying wide characters. More details are
+given in
+"Input encoding"
+above.
+

+

+Generating long repetitive patterns
+

+

+Some tests use long patterns that are very repetitive. Instead of creating a
+very long input line for such a pattern, you can use a special repetition
+feature, similar to the one described for subject lines above. If the
+expand modifier is present on a pattern, parts of the pattern that have
+the form
+
+  \[<characters>]{<count>}
+

+are expanded before the pattern is passed to pcre2_compile(). For
+example, \[AB]{6000} is expanded to "ABAB..." 6000 times. This construction
+cannot be nested. An initial "\[" sequence is recognized only if "]{" followed
+by decimal digits and "}" is found later in the pattern. If not, the characters
+remain in the pattern unaltered. The expand and hex modifiers are
+mutually exclusive.
+

+

+If part of an expanded pattern looks like an expansion, but is really part of
+the actual pattern, unwanted expansion can be avoided by giving two values in
+the quantifier. For example, \[AB]{6000,6000} is not recognized as an
+expansion item.
+

+

+If the info modifier is set on an expanded pattern, the result of the
+expansion is included in the information that is output.
+

+

+JIT compilation
+

+

+Just-in-time (JIT) compiling is a heavyweight optimization that can greatly
+speed up pattern matching. See the
+pcre2jit
+documentation for details. JIT compiling happens, optionally, after a pattern
+has been successfully compiled into an internal form. The JIT compiler converts
+this to optimized machine code. It needs to know whether the match-time options
+PCRE2_PARTIAL_HARD and PCRE2_PARTIAL_SOFT are going to be used, because
+different code is generated for the different cases. See the partial
+modifier in "Subject Modifiers"
+below
+for details of how these options are specified for each match attempt.
+

+

+JIT compilation is requested by the jit pattern modifier, which may
+optionally be followed by an equals sign and a number in the range 0 to 7.
+The three bits that make up the number specify which of the three JIT operating
+modes are to be compiled:
+
+  1  compile JIT code for non-partial matching
+  2  compile JIT code for soft partial matching
+  4  compile JIT code for hard partial matching
+

+The possible values for the jit modifier are therefore:
+
+  0  disable JIT
+  1  normal matching only
+  2  soft partial matching only
+  3  normal and soft partial matching
+  4  hard partial matching only
+  6  soft and hard partial matching only
+  7  all three modes
+

+If no number is given, 7 is assumed. The phrase "partial matching" means a call
+to pcre2_match() with either the PCRE2_PARTIAL_SOFT or the
+PCRE2_PARTIAL_HARD option set. Note that such a call may return a complete
+match; the options enable the possibility of a partial match, but do not
+require it. Note also that if you request JIT compilation only for partial
+matching (for example, jit=2) but do not set the partial modifier on a
+subject line, that match will not use JIT code because none was compiled for
+non-partial matching.
+

+

+If JIT compilation is successful, the compiled JIT code will automatically be
+used when an appropriate type of match is run, except when incompatible
+run-time options are specified. For more details, see the
+pcre2jit
+documentation. See also the jitstack modifier below for a way of
+setting the size of the JIT stack.
+

+

+If the jitfast modifier is specified, matching is done using the JIT
+"fast path" interface, pcre2_jit_match(), which skips some of the sanity
+checks that are done by pcre2_match(), and of course does not work when
+JIT is not supported. If jitfast is specified without jit, jit=7 is
+assumed.
+

+

+If the jitverify modifier is specified, information about the compiled
+pattern shows whether JIT compilation was or was not successful. If
+jitverify is specified without jit, jit=7 is assumed. If JIT
+compilation is successful when jitverify is set, the text "(JIT)" is
+added to the first output line after a match or non match when JIT-compiled
+code was actually used in the match.
+

+

+Setting a locale
+

+

+The locale modifier must specify the name of a locale, for example:
+
+  /pattern/locale=fr_FR
+

+The given locale is set, pcre2_maketables() is called to build a set of
+character tables for the locale, and this is then passed to
+pcre2_compile() when compiling the regular expression. The same tables
+are used when matching the following subject lines. The locale modifier
+applies only to the pattern on which it appears, but can be given in a
+#pattern command if a default is needed. Setting a locale and alternate
+character tables are mutually exclusive.
+

+

+Showing pattern memory
+

+

+The memory modifier causes the size in bytes of the memory used to hold
+the compiled pattern to be output. This does not include the size of the
+pcre2_code block; it is just the actual compiled data. If the pattern is
+subsequently passed to the JIT compiler, the size of the JIT compiled code is
+also output. Here is an example:
+
+    re> /a(b)c/jit,memory
+  Memory allocation (code space): 21
+  Memory allocation (JIT code): 1910
+
+

+

+

+Limiting nested parentheses
+

+

+The parens_nest_limit modifier sets a limit on the depth of nested
+parentheses in a pattern. Breaching the limit causes a compilation error.
+The default for the library is set when PCRE2 is built, but pcre2test
+sets its own default of 220, which is required for running the standard test
+suite.
+

+

+Limiting the pattern length
+

+

+The max_pattern_length modifier sets a limit, in code units, to the
+length of pattern that pcre2_compile() will accept. Breaching the limit
+causes a compilation error. The default is the largest number a PCRE2_SIZE
+variable can hold (essentially unlimited).
+

+

+Limiting the size of a compiled pattern
+

+

+The max_pattern_compiled_length modifier sets a limit, in bytes, to the
+amount of memory used by a compiled pattern. Breaching the limit causes a
+compilation error. The default is the largest number a PCRE2_SIZE variable can
+hold (essentially unlimited).
+

+

+Using the POSIX wrapper API
+

+

+The posix and posix_nosub modifiers cause pcre2test to call
+PCRE2 via the POSIX wrapper API rather than its native API. When
+posix_nosub is used, the POSIX option REG_NOSUB is passed to
+regcomp(). The POSIX wrapper supports only the 8-bit library. Note that
+it does not imply POSIX matching semantics; for more detail see the
+pcre2posix
+documentation. The following pattern modifiers set options for the
+regcomp() function:
+
+  caseless           REG_ICASE
+  multiline          REG_NEWLINE
+  dotall             REG_DOTALL     )
+  ungreedy           REG_UNGREEDY   ) These options are not part of
+  ucp                REG_UCP        )   the POSIX standard
+  utf                REG_UTF8       )
+

+The regerror_buffsize modifier specifies a size for the error buffer that
+is passed to regerror() in the event of a compilation error. For example:
+
+  /abc/posix,regerror_buffsize=20
+

+This provides a means of testing the behaviour of regerror() when the
+buffer is too small for the error message. If this modifier has not been set, a
+large buffer is used.
+

+

+The aftertext and allaftertext subject modifiers work as described
+below. All other modifiers are either ignored, with a warning message, or cause
+an error.
+

+

+The pattern is passed to regcomp() as a zero-terminated string by
+default, but if the use_length or hex modifiers are set, the
+REG_PEND extension is used to pass it by length.
+

+

+Testing the stack guard feature
+

+

+The stackguard modifier is used to test the use of
+pcre2_set_compile_recursion_guard(), a function that is provided to
+enable stack availability to be checked during compilation (see the
+pcre2api
+documentation for details). If the number specified by the modifier is greater
+than zero, pcre2_set_compile_recursion_guard() is called to set up
+callback from pcre2_compile() to a local function. The argument it
+receives is the current nesting parenthesis depth; if this is greater than the
+value given by the modifier, non-zero is returned, causing the compilation to
+be aborted.
+

+

+Using alternative character tables
+

+

+The value specified for the tables modifier must be one of the digits 0,
+1, 2, or 3. It causes a specific set of built-in character tables to be passed
+to pcre2_compile(). This is used in the PCRE2 tests to check behaviour
+with different character tables. The digit specifies the tables as follows:
+
+  0   do not pass any special character tables
+  1   the default ASCII tables, as distributed in
+        pcre2_chartables.c.dist
+  2   a set of tables defining ISO 8859 characters
+  3   a set of tables loaded by the #loadtables command
+

+In tables 2, some characters whose codes are greater than 128 are identified as
+letters, digits, spaces, etc. Tables 3 can be used only after a
+#loadtables command has loaded them from a binary file. Setting alternate
+character tables and a locale are mutually exclusive.
+

+

+Setting certain match controls
+

+

+The following modifiers are really subject modifiers, and are described under
+"Subject Modifiers" below. However, they may be included in a pattern's
+modifier list, in which case they are applied to every subject line that is
+processed with that pattern. These modifiers do not affect the compilation
+process.
+
+      aftertext                   show text after match
+      allaftertext                show text after captures
+      allcaptures                 show all captures
+      allvector                   show the entire ovector
+      allusedtext                 show all consulted text
+      altglobal                   alternative global matching
+  /g  global                      global matching
+      heapframes_size             show match data heapframes size
+      jitstack=<n>                set size of JIT stack
+      mark                        show mark values
+      replace=<string>            specify a replacement string
+      startchar                   show starting character when relevant
+      substitute_callout          use substitution callouts
+      substitute_extended         use PCRE2_SUBSTITUTE_EXTENDED
+      substitute_literal          use PCRE2_SUBSTITUTE_LITERAL
+      substitute_matched          use PCRE2_SUBSTITUTE_MATCHED
+      substitute_overflow_length  use PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+      substitute_replacement_only use PCRE2_SUBSTITUTE_REPLACEMENT_ONLY
+      substitute_skip=<n>         skip substitution <n>
+      substitute_stop=<n>         skip substitution <n> and following
+      substitute_unknown_unset    use PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+      substitute_unset_empty      use PCRE2_SUBSTITUTE_UNSET_EMPTY
+

+These modifiers may not appear in a #pattern command. If you want them as
+defaults, set them in a #subject command.
+

+

+Specifying literal subject lines
+

+

+If the subject_literal modifier is present on a pattern, all the subject
+lines that it matches are taken as literal strings, with no interpretation of
+backslashes. It is not possible to set subject modifiers on such lines, but any
+that are set as defaults by a #subject command are recognized.
+

+

+Saving a compiled pattern
+

+

+When a pattern with the push modifier is successfully compiled, it is
+pushed onto a stack of compiled patterns, and pcre2test expects the next
+line to contain a new pattern (or a command) instead of a subject line. This
+facility is used when saving compiled patterns to a file, as described in the
+section entitled "Saving and restoring compiled patterns"
+below.
+If pushcopy is used instead of push, a copy of the compiled
+pattern is stacked, leaving the original as current, ready to match the
+following input lines. This provides a way of testing the
+pcre2_code_copy() function.
+The push and pushcopy  modifiers are incompatible with compilation
+modifiers such as global that act at match time. Any that are specified
+are ignored (for the stacked copy), with a warning message, except for
+replace, which causes an error. Note that jitverify, which is
+allowed, does not carry through to any subsequent matching that uses a stacked
+pattern.
+

+

+Testing foreign pattern conversion
+

+

+The experimental foreign pattern conversion functions in PCRE2 can be tested by
+setting the convert modifier. Its argument is a colon-separated list of
+options, which set the equivalent option for the pcre2_pattern_convert()
+function:
+
+  glob                    PCRE2_CONVERT_GLOB
+  glob_no_starstar        PCRE2_CONVERT_GLOB_NO_STARSTAR
+  glob_no_wild_separator  PCRE2_CONVERT_GLOB_NO_WILD_SEPARATOR
+  posix_basic             PCRE2_CONVERT_POSIX_BASIC
+  posix_extended          PCRE2_CONVERT_POSIX_EXTENDED
+  unset                   Unset all options
+

+The "unset" value is useful for turning off a default that has been set by a
+#pattern command. When one of these options is set, the input pattern is
+passed to pcre2_pattern_convert(). If the conversion is successful, the
+result is reflected in the output and then passed to pcre2_compile(). The
+normal utf and no_utf_check options, if set, cause the
+PCRE2_CONVERT_UTF and PCRE2_CONVERT_NO_UTF_CHECK options to be passed to
+pcre2_pattern_convert().
+

+

+By default, the conversion function is allowed to allocate a buffer for its
+output. However, if the convert_length modifier is set to a value greater
+than zero, pcre2test passes a buffer of the given length. This makes it
+possible to test the length check.
+

+

+The convert_glob_escape and convert_glob_separator modifiers can be
+used to specify the escape and separator characters for glob processing,
+overriding the defaults, which are operating-system dependent.
+

+
SUBJECT MODIFIERS

+

+The modifiers that can appear in subject lines and the #subject
+command are of two types.
+

+

+Setting match options
+

+

+The following modifiers set options for pcre2_match() or
+pcre2_dfa_match(). See
+pcreapi
+for a description of their effects.
+
+      anchored                   set PCRE2_ANCHORED
+      endanchored                set PCRE2_ENDANCHORED
+      dfa_restart                set PCRE2_DFA_RESTART
+      dfa_shortest               set PCRE2_DFA_SHORTEST
+      disable_recurseloop_check  set PCRE2_DISABLE_RECURSELOOP_CHECK
+      no_jit                     set PCRE2_NO_JIT
+      no_utf_check               set PCRE2_NO_UTF_CHECK
+      notbol                     set PCRE2_NOTBOL
+      notempty                   set PCRE2_NOTEMPTY
+      notempty_atstart           set PCRE2_NOTEMPTY_ATSTART
+      noteol                     set PCRE2_NOTEOL
+      partial_hard (or ph)       set PCRE2_PARTIAL_HARD
+      partial_soft (or ps)       set PCRE2_PARTIAL_SOFT
+

+The partial matching modifiers are provided with abbreviations because they
+appear frequently in tests.
+

+

+If the posix or posix_nosub modifier was present on the pattern,
+causing the POSIX wrapper API to be used, the only option-setting modifiers
+that have any effect are notbol, notempty, and noteol,
+causing REG_NOTBOL, REG_NOTEMPTY, and REG_NOTEOL, respectively, to be passed to
+regexec(). The other modifiers are ignored, with a warning message.
+

+

+There is one additional modifier that can be used with the POSIX wrapper. It is
+ignored (with a warning) if used for non-POSIX matching.
+
+      posix_startend=<n>[:<m>]
+

+This causes the subject string to be passed to regexec() using the
+REG_STARTEND option, which uses offsets to specify which part of the string is
+searched. If only one number is given, the end offset is passed as the end of
+the subject string. For more detail of REG_STARTEND, see the
+pcre2posix
+documentation. If the subject string contains binary zeros (coded as escapes
+such as \x{00} because pcre2test does not support actual binary zeros in
+its input), you must use posix_startend to specify its length.
+

+

+Setting match controls
+

+

+The following modifiers affect the matching process or request additional
+information. Some of them may also be specified on a pattern line (see above),
+in which case they apply to every subject line that is matched against that
+pattern, but can be overridden by modifiers on the subject.
+
+      aftertext                  show text after match
+      allaftertext               show text after captures
+      allcaptures                show all captures
+      allvector                  show the entire ovector
+      allusedtext                show all consulted text (non-JIT only)
+      altglobal                  alternative global matching
+      callout_capture            show captures at callout time
+      callout_data=<n>           set a value to pass via callouts
+      callout_error=<n>[:<m>]    control callout error
+      callout_extra              show extra callout information
+      callout_fail=<n>[:<m>]     control callout failure
+      callout_no_where           do not show position of a callout
+      callout_none               do not supply a callout function
+      copy=<number or name>      copy captured substring
+      depth_limit=<n>            set a depth limit
+      dfa                        use pcre2_dfa_match()
+      find_limits                find heap, match and depth limits
+      find_limits_noheap         find match and depth limits
+      get=<number or name>       extract captured substring
+      getall                     extract all captured substrings
+  /g  global                     global matching
+      heapframes_size            show match data heapframes size
+      heap_limit=<n>             set a limit on heap memory (Kbytes)
+      jitstack=<n>               set size of JIT stack
+      mark                       show mark values
+      match_limit=<n>            set a match limit

+

+The effects of these modifiers are described in the following sections. When
+matching via the POSIX wrapper API, the aftertext, allaftertext,
+and ovector subject modifiers work as described below. All other
+modifiers are either ignored, with a warning message, or cause an error.
+

+

+Showing more text
+

+

+The aftertext modifier requests that as well as outputting the part of
+the subject string that matched the entire pattern, pcre2test should in
+addition output the remainder of the subject string. This is useful for tests
+where the subject contains multiple copies of the same substring. The
+allaftertext modifier requests the same action for captured substrings as
+well as the main matched substring. In each case the remainder is output on the
+following line with a plus character following the capture number.
+

+

+The allusedtext modifier requests that all the text that was consulted
+during a successful pattern match by the interpreter should be shown, for both
+full and partial matches. This feature is not supported for JIT matching, and
+if requested with JIT it is ignored (with a warning message). Setting this
+modifier affects the output if there is a lookbehind at the start of a match,
+or, for a complete match, a lookahead at the end, or if \K is used in the
+pattern. Characters that precede or follow the start and end of the actual
+match are indicated in the output by '<' or '>' characters underneath them.
+Here is an example:
+
+    re> /(?<=pqr)abc(?=xyz)/
+  data> 123pqrabcxyz456\=allusedtext
+   0: pqrabcxyz
+      <<<   >>>
+  data> 123pqrabcxy\=ph,allusedtext
+  Partial match: pqrabcxy
+                 <<<
+

+The first, complete match shows that the matched string is "abc", with the
+preceding and following strings "pqr" and "xyz" having been consulted during
+the match (when processing the assertions). The partial match can indicate only
+the preceding string.
+

+

+The startchar modifier requests that the starting character for the match
+be indicated, if it is different to the start of the matched string. The only
+time when this occurs is when \K has been processed as part of the match. In
+this situation, the output for the matched string is displayed from the
+starting character instead of from the match point, with circumflex characters
+under the earlier characters. For example:
+
+    re> /abc\Kxyz/
+  data> abcxyz\=startchar
+   0: abcxyz
+      ^^^
+

+Unlike allusedtext, the startchar modifier can be used with JIT.
+However, these two modifiers are mutually exclusive.
+

+

+Showing the value of all capture groups
+

+

+The allcaptures modifier requests that the values of all potential
+captured parentheses be output after a match. By default, only those up to the
+highest one actually used in the match are output (corresponding to the return
+code from pcre2_match()). Groups that did not take part in the match
+are output as "<unset>". This modifier is not relevant for DFA matching (which
+does no capturing) and does not apply when replace is specified; it is
+ignored, with a warning message, if present.
+

+

+Showing the entire ovector, for all outcomes
+

+

+The allvector modifier requests that the entire ovector be shown,
+whatever the outcome of the match. Compare allcaptures, which shows only
+up to the maximum number of capture groups for the pattern, and then only for a
+successful complete non-DFA match. This modifier, which acts after any match
+result, and also for DFA matching, provides a means of checking that there are
+no unexpected modifications to ovector fields. Before each match attempt, the
+ovector is filled with a special value, and if this is found in both elements
+of a capturing pair, "<unchanged>" is output. After a successful match, this
+applies to all groups after the maximum capture group for the pattern. In other
+cases it applies to the entire ovector. After a partial match, the first two
+elements are the only ones that should be set. After a DFA match, the amount of
+ovector that is used depends on the number of matches that were found.
+

+

+Testing pattern callouts
+

+

+A callout function is supplied when pcre2test calls the library matching
+functions, unless callout_none is specified. Its behaviour can be
+controlled by various modifiers listed above whose names begin with
+callout_. Details are given in the section entitled "Callouts"
+below.
+Testing callouts from pcre2_substitute() is described separately in
+"Testing the substitution function"
+below.
+

+

+Finding all matches in a string
+

+

+Searching for all possible matches within a subject can be requested by the
+global or altglobal modifier. After finding a match, the matching
+function is called again to search the remainder of the subject. The difference
+between global and altglobal is that the former uses the
+start_offset argument to pcre2_match() or pcre2_dfa_match()
+to start searching at a new point within the entire string (which is what Perl
+does), whereas the latter passes over a shortened subject. This makes a
+difference to the matching process if the pattern begins with a lookbehind
+assertion (including \b or \B).
+

+

+If an empty string is matched, the next match is done with the
+PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set, in order to search for
+another, non-empty, match at the same point in the subject. If this match
+fails, the start offset is advanced, and the normal match is retried. This
+imitates the way Perl handles such cases when using the /g modifier or
+the split() function. Normally, the start offset is advanced by one
+character, but if the newline convention recognizes CRLF as a newline, and the
+current character is CR followed by LF, an advance of two characters occurs.
+

+

+Testing substring extraction functions
+

+

+The copy and get modifiers can be used to test the
+pcre2_substring_copy_xxx() and pcre2_substring_get_xxx() functions.
+They can be given more than once, and each can specify a capture group name or
+number, for example:
+
+   abcd\=copy=1,copy=3,get=G1
+

+If the #subject command is used to set default copy and/or get lists,
+these can be unset by specifying a negative number to cancel all numbered
+groups and an empty name to cancel all named groups.
+

+

+The getall modifier tests pcre2_substring_list_get(), which
+extracts all captured substrings.
+

+

+If the subject line is successfully matched, the substrings extracted by the
+convenience functions are output with C, G, or L after the string number
+instead of a colon. This is in addition to the normal full list. The string
+length (that is, the return from the extraction function) is given in
+parentheses after each substring, followed by the name when the extraction was
+by name.
+

+

+Testing the substitution function
+

+

+If the replace modifier is set, the pcre2_substitute() function is
+called instead of one of the matching functions (or after one call of
+pcre2_match() in the case of PCRE2_SUBSTITUTE_MATCHED). Note that
+replacement strings cannot contain commas, because a comma signifies the end of
+a modifier. This is not thought to be an issue in a test program.
+

+

+Specifying a completely empty replacement string disables this modifier.
+However, it is possible to specify an empty replacement by providing a buffer
+length, as described below, for an otherwise empty replacement.
+

+

+Unlike subject strings, pcre2test does not process replacement strings
+for escape sequences. In UTF mode, a replacement string is checked to see if it
+is a valid UTF-8 string. If so, it is correctly converted to a UTF string of
+the appropriate code unit width. If it is not a valid UTF-8 string, the
+individual code units are copied directly. This provides a means of passing an
+invalid UTF-8 string for testing purposes.
+

+

+The following modifiers set options (in additional to the normal match options)
+for pcre2_substitute():
+
+  global                      PCRE2_SUBSTITUTE_GLOBAL
+  substitute_extended         PCRE2_SUBSTITUTE_EXTENDED
+  substitute_literal          PCRE2_SUBSTITUTE_LITERAL
+  substitute_matched          PCRE2_SUBSTITUTE_MATCHED
+  substitute_overflow_length  PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+  substitute_replacement_only PCRE2_SUBSTITUTE_REPLACEMENT_ONLY
+  substitute_unknown_unset    PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+  substitute_unset_empty      PCRE2_SUBSTITUTE_UNSET_EMPTY
+

+See the
+pcre2api
+documentation for details of these options.
+

+

+After a successful substitution, the modified string is output, preceded by the
+number of replacements. This may be zero if there were no matches. Here is a
+simple example of a substitution test:
+
+  /abc/replace=xxx
+      =abc=abc=
+   1: =xxx=abc=
+      =abc=abc=\=global
+   2: =xxx=xxx=
+

+Subject and replacement strings should be kept relatively short (fewer than 256
+characters) for substitution tests, as fixed-size buffers are used. To make it
+easy to test for buffer overflow, if the replacement string starts with a
+number in square brackets, that number is passed to pcre2_substitute() as
+the size of the output buffer, with the replacement string starting at the next
+character. Here is an example that tests the edge case:
+
+  /abc/
+      123abc123\=replace=[10]XYZ
+   1: 123XYZ123
+      123abc123\=replace=[9]XYZ
+  Failed: error -47: no more memory
+

+The default action of pcre2_substitute() is to return
+PCRE2_ERROR_NOMEMORY when the output buffer is too small. However, if the
+PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option is set (by using the
+substitute_overflow_length modifier), pcre2_substitute() continues
+to go through the motions of matching and substituting (but not doing any
+callouts), in order to compute the size of buffer that is required. When this
+happens, pcre2test shows the required buffer length (which includes space
+for the trailing zero) as part of the error message. For example:
+
+  /abc/substitute_overflow_length
+      123abc123\=replace=[9]XYZ
+  Failed: error -47: no more memory: 10 code units are needed
+

+A replacement string is ignored with POSIX and DFA matching. Specifying partial
+matching provokes an error return ("bad option value") from
+pcre2_substitute().
+

+

+Testing substitute callouts
+

+

+If the substitute_callout modifier is set, a substitution callout
+function is set up. The null_context modifier must not be set, because
+the address of the callout function is passed in a match context. When the
+callout function is called (after each substitution), details of the input
+and output strings are output. For example:
+
+  /abc/g,replace=<$0>,substitute_callout
+      abcdefabcpqr
+   1(1) Old 0 3 "abc" New 0 5 "<abc>"
+   2(1) Old 6 9 "abc" New 8 13 "<abc>"
+   2: <abc>def<abc>pqr
+

+The first number on each callout line is the count of matches. The
+parenthesized number is the number of pairs that are set in the ovector (that
+is, one more than the number of capturing groups that were set). Then are
+listed the offsets of the old substring, its contents, and the same for the
+replacement.
+

+

+By default, the substitution callout function returns zero, which accepts the
+replacement and causes matching to continue if /g was used. Two further
+modifiers can be used to test other return values. If substitute_skip is
+set to a value greater than zero the callout function returns +1 for the match
+of that number, and similarly substitute_stop returns -1. These cause the
+replacement to be rejected, and -1 causes no further matching to take place. If
+either of them are set, substitute_callout is assumed. For example:
+
+  /abc/g,replace=<$0>,substitute_skip=1
+      abcdefabcpqr
+   1(1) Old 0 3 "abc" New 0 5 "<abc> SKIPPED"
+   2(1) Old 6 9 "abc" New 6 11 "<abc>"
+   2: abcdef<abc>pqr
+      abcdefabcpqr\=substitute_stop=1
+   1(1) Old 0 3 "abc" New 0 5 "<abc> STOPPED"
+   1: abcdefabcpqr
+

+If both are set for the same number, stop takes precedence. Only a single skip
+or stop is supported, which is sufficient for testing that the feature works.
+

+

+Setting the JIT stack size
+

+

+The jitstack modifier provides a way of setting the maximum stack size
+that is used by the just-in-time optimization code. It is ignored if JIT
+optimization is not being used. The value is a number of kibibytes (units of
+1024 bytes). Setting zero reverts to the default of 32KiB. Providing a stack
+that is larger than the default is necessary only for very complicated
+patterns. If jitstack is set non-zero on a subject line it overrides any
+value that was set on the pattern.
+

+

+Setting heap, match, and depth limits
+

+

+The heap_limit, match_limit, and depth_limit modifiers set
+the appropriate limits in the match context. These values are ignored when the
+find_limits or find_limits_noheap modifier is specified.
+

+

+Finding minimum limits
+

+

+If the find_limits modifier is present on a subject line, pcre2test
+calls the relevant matching function several times, setting different values in
+the match context via pcre2_set_heap_limit(),
+pcre2_set_match_limit(), or pcre2_set_depth_limit() until it finds
+the smallest value for each parameter that allows the match to complete without
+a "limit exceeded" error. The match itself may succeed or fail. An alternative
+modifier, find_limits_noheap, omits the heap limit. This is used in the
+standard tests, because the minimum heap limit varies between systems. If JIT
+is being used, only the match limit is relevant, and the other two are
+automatically omitted.
+

+

+When using this modifier, the pattern should not contain any limit settings
+such as (*LIMIT_MATCH=...) within it. If such a setting is present and is
+lower than the minimum matching value, the minimum value cannot be found
+because pcre2_set_match_limit() etc. are only able to reduce the value of
+an in-pattern limit; they cannot increase it.
+

+

+For non-DFA matching, the minimum depth_limit number is a measure of how
+much nested backtracking happens (that is, how deeply the pattern's tree is
+searched). In the case of DFA matching, depth_limit controls the depth of
+recursive calls of the internal function that is used for handling pattern
+recursion, lookaround assertions, and atomic groups.
+

+

+For non-DFA matching, the match_limit number is a measure of the amount
+of backtracking that takes place, and learning the minimum value can be
+instructive. For most simple matches, the number is quite small, but for
+patterns with very large numbers of matching possibilities, it can become large
+very quickly with increasing length of subject string. In the case of DFA
+matching, match_limit controls the total number of calls, both recursive
+and non-recursive, to the internal matching function, thus controlling the
+overall amount of computing resource that is used.
+

+

+For both kinds of matching, the heap_limit number, which is in kibibytes
+(units of 1024 bytes), limits the amount of heap memory used for matching.
+

+

+Showing MARK names
+

+

+The mark modifier causes the names from backtracking control verbs that
+are returned from calls to pcre2_match() to be displayed. If a mark is
+returned for a match, non-match, or partial match, pcre2test shows it.
+For a match, it is on a line by itself, tagged with "MK:". Otherwise, it
+is added to the non-match message.
+

+

+Showing memory usage
+

+

+The memory modifier causes pcre2test to log the sizes of all heap
+memory allocation and freeing calls that occur during a call to
+pcre2_match() or pcre2_dfa_match(). In the latter case, heap memory
+is used only when a match requires more internal workspace that the default
+allocation on the stack, so in many cases there will be no output. No heap
+memory is allocated during matching with JIT. For this modifier to work, the
+null_context modifier must not be set on both the pattern and the
+subject, though it can be set on one or the other.
+

+

+Showing the heap frame overall vector size
+

+

+The heapframes_size modifier is relevant for matches using
+pcre2_match() without JIT. After a match has run (whether successful or
+not) the size, in bytes, of the allocated heap frames vector that is left
+attached to the match data block is shown. If the matching action involved
+several calls to pcre2_match() (for example, global matching or for
+timing) only the final value is shown.
+

+

+This modifier is ignored, with a warning, for POSIX or DFA matching. JIT
+matching does not use the heap frames vector, so the size is always zero,
+unless there was a previous non-JIT match. Note that specifing a size of zero
+for the output vector (see below) causes pcre2test to free its match data
+block (and associated heap frames vector) and allocate a new one.
+

+

+Setting a starting offset
+

+

+The offset modifier sets an offset in the subject string at which
+matching starts. Its value is a number of code units, not characters.
+

+

+Setting an offset limit
+

+

+The offset_limit modifier sets a limit for unanchored matches. If a match
+cannot be found starting at or before this offset in the subject, a "no match"
+return is given. The data value is a number of code units, not characters. When
+this modifier is used, the use_offset_limit modifier must have been set
+for the pattern; if not, an error is generated.
+

+

+Setting the size of the output vector
+

+

+The ovector modifier applies only to the subject line in which it
+appears, though of course it can also be used to set a default in a
+#subject command. It specifies the number of pairs of offsets that are
+available for storing matching information. The default is 15.
+

+

+A value of zero is useful when testing the POSIX API because it causes
+regexec() to be called with a NULL capture vector. When not testing the
+POSIX API, a value of zero is used to cause
+pcre2_match_data_create_from_pattern() to be called, in order to create a
+new match block of exactly the right size for the pattern. (It is not possible
+to create a match block with a zero-length ovector; there is always at least
+one pair of offsets.) The old match data block is freed.
+

+

+Passing the subject as zero-terminated
+

+

+By default, the subject string is passed to a native API matching function with
+its correct length. In order to test the facility for passing a zero-terminated
+string, the zero_terminate modifier is provided. It causes the length to
+be passed as PCRE2_ZERO_TERMINATED. When matching via the POSIX interface,
+this modifier is ignored, with a warning.
+

+

+When testing pcre2_substitute(), this modifier also has the effect of
+passing the replacement string as zero-terminated.
+

+

+Passing a NULL context, subject, or replacement
+

+

+Normally, pcre2test passes a context block to pcre2_match(),
+pcre2_dfa_match(), pcre2_jit_match() or pcre2_substitute().
+If the null_context modifier is set, however, NULL is passed. This is for
+testing that the matching and substitution functions behave correctly in this
+case (they use default values). This modifier cannot be used with the
+find_limits, find_limits_noheap, or substitute_callout
+modifiers.
+

+

+Similarly, for testing purposes, if the null_subject or
+null_replacement modifier is set, the subject or replacement string
+pointers are passed as NULL, respectively, to the relevant functions.
+

+
THE ALTERNATIVE MATCHING FUNCTION

+

+By default, pcre2test uses the standard PCRE2 matching function,
+pcre2_match() to match each subject line. PCRE2 also supports an
+alternative matching function, pcre2_dfa_match(), which operates in a
+different way, and has some restrictions. The differences between the two
+functions are described in the
+pcre2matching
+documentation.
+

+

+If the dfa modifier is set, the alternative matching function is used.
+This function finds all possible matches at a given point in the subject. If,
+however, the dfa_shortest modifier is set, processing stops after the
+first match is found. This is always the shortest possible match.
+

+
DEFAULT OUTPUT FROM pcre2test

+

+This section describes the output when the normal matching function,
+pcre2_match(), is being used.
+

+

+When a match succeeds, pcre2test outputs the list of captured substrings,
+starting with number 0 for the string that matched the whole pattern.
+Otherwise, it outputs "No match" when the return is PCRE2_ERROR_NOMATCH, or
+"Partial match:" followed by the partially matching substring when the
+return is PCRE2_ERROR_PARTIAL. (Note that this is the
+entire substring that was inspected during the partial match; it may include
+characters before the actual match start if a lookbehind assertion, \K, \b,
+or \B was involved.)
+

+

+For any other return, pcre2test outputs the PCRE2 negative error number
+and a short descriptive phrase. If the error is a failed UTF string check, the
+code unit offset of the start of the failing character is also output. Here is
+an example of an interactive pcre2test run.
+
+  $ pcre2test
+  PCRE2 version 10.22 2016-07-29
+
+    re> /^abc(\d+)/
+  data> abc123
+   0: abc123
+   1: 123
+  data> xyz
+  No match
+

+Unset capturing substrings that are not followed by one that is set are not
+shown by pcre2test unless the allcaptures modifier is specified. In
+the following example, there are two capturing substrings, but when the first
+data line is matched, the second, unset substring is not shown. An "internal"
+unset substring is shown as "<unset>", as for the second data line.
+
+    re> /(a)|(b)/
+  data> a
+   0: a
+   1: a
+  data> b
+   0: b
+   1: <unset>
+   2: b
+

+If the strings contain any non-printing characters, they are output as \xhh
+escapes if the value is less than 256 and UTF mode is not set. Otherwise they
+are output as \x{hh...} escapes. See below for the definition of non-printing
+characters. If the aftertext modifier is set, the output for substring 0
+is followed by the rest of the subject string, identified by "0+" like this:
+
+    re> /cat/aftertext
+  data> cataract
+   0: cat
+   0+ aract
+

+If global matching is requested, the results of successive matching attempts
+are output in sequence, like this:
+
+    re> /\Bi(\w\w)/g
+  data> Mississippi
+   0: iss
+   1: ss
+   0: iss
+   1: ss
+   0: ipp
+   1: pp
+

+"No match" is output only if the first match attempt fails. Here is an example
+of a failure message (the offset 4 that is specified by the offset
+modifier is past the end of the subject string):
+
+    re> /xyz/
+  data> xyz\=offset=4
+  Error -24 (bad offset value)
+

+

+

+Note that whereas patterns can be continued over several lines (a plain ">"
+prompt is used for continuations), subject lines may not. However newlines can
+be included in a subject by means of the \n escape (or \r, \r\n, etc.,
+depending on the newline sequence setting).
+

+
OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION

+

+When the alternative matching function, pcre2_dfa_match(), is used, the
+output consists of a list of all the matches that start at the first point in
+the subject where there is at least one match. For example:
+
+    re> /(tang|tangerine|tan)/
+  data> yellow tangerine\=dfa
+   0: tangerine
+   1: tang
+   2: tan
+

+Using the normal matching function on this data finds only "tang". The
+longest matching string is always given first (and numbered zero). After a
+PCRE2_ERROR_PARTIAL return, the output is "Partial match:", followed by the
+partially matching substring. Note that this is the entire substring that was
+inspected during the partial match; it may include characters before the actual
+match start if a lookbehind assertion, \b, or \B was involved. (\K is not
+supported for DFA matching.)
+

+

+If global matching is requested, the search for further matches resumes
+at the end of the longest match. For example:
+
+    re> /(tang|tangerine|tan)/g
+  data> yellow tangerine and tangy sultana\=dfa
+   0: tangerine
+   1: tang
+   2: tan
+   0: tang
+   1: tan
+   0: tan
+

+The alternative matching function does not support substring capture, so the
+modifiers that are concerned with captured substrings are not relevant.
+

+
RESTARTING AFTER A PARTIAL MATCH

+

+When the alternative matching function has given the PCRE2_ERROR_PARTIAL
+return, indicating that the subject partially matched the pattern, you can
+restart the match with additional subject data by means of the
+dfa_restart modifier. For example:
+
+    re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+  data> 23ja\=ps,dfa
+  Partial match: 23ja
+  data> n05\=dfa,dfa_restart
+   0: n05
+

+For further information about partial matching, see the
+pcre2partial
+documentation.
+

+
CALLOUTS

+

+If the pattern contains any callout requests, pcre2test's callout
+function is called during matching unless callout_none is specified. This
+works with both matching functions, and with JIT, though there are some
+differences in behaviour. The output for callouts with numerical arguments and
+those with string arguments is slightly different.
+

+

+Callouts with numerical arguments
+

+

+By default, the callout function displays the callout number, the start and
+current positions in the subject text at the callout time, and the next pattern
+item to be tested. For example:
+
+  --->pqrabcdef
+    0    ^  ^     \d
+

+This output indicates that callout number 0 occurred for a match attempt
+starting at the fourth character of the subject string, when the pointer was at
+the seventh character, and when the next pattern item was \d. Just
+one circumflex is output if the start and current positions are the same, or if
+the current position precedes the start position, which can happen if the
+callout is in a lookbehind assertion.
+

+

+Callouts numbered 255 are assumed to be automatic callouts, inserted as a
+result of the auto_callout pattern modifier. In this case, instead of
+showing the callout number, the offset in the pattern, preceded by a plus, is
+output. For example:
+
+    re> /\d?[A-E]\*/auto_callout
+  data> E*
+  --->E*
+   +0 ^      \d?
+   +3 ^      [A-E]
+   +8 ^^     \*
+  +10 ^ ^
+   0: E*
+

+If a pattern contains (*MARK) items, an additional line is output whenever
+a change of latest mark is passed to the callout function. For example:
+
+    re> /a(*MARK:X)bc/auto_callout
+  data> abc
+  --->abc
+   +0 ^       a
+   +1 ^^      (*MARK:X)
+  +10 ^^      b
+  Latest Mark: X
+  +11 ^ ^     c
+  +12 ^  ^
+   0: abc
+

+The mark changes between matching "a" and "b", but stays the same for the rest
+of the match, so nothing more is output. If, as a result of backtracking, the
+mark reverts to being unset, the text "<unset>" is output.
+

+

+Callouts with string arguments
+

+

+The output for a callout with a string argument is similar, except that instead
+of outputting a callout number before the position indicators, the callout
+string and its offset in the pattern string are output before the reflection of
+the subject string, and the subject string is reflected for each callout. For
+example:
+
+    re> /^ab(?C'first')cd(?C"second")ef/
+  data> abcdefg
+  Callout (7): 'first'
+  --->abcdefg
+      ^ ^         c
+  Callout (20): "second"
+  --->abcdefg
+      ^   ^       e
+   0: abcdef
+
+

+

+

+Callout modifiers
+

+

+The callout function in pcre2test returns zero (carry on matching) by
+default, but you can use a callout_fail modifier in a subject line to
+change this and other parameters of the callout (see below).
+

+

+If the callout_capture modifier is set, the current captured groups are
+output when a callout occurs. This is useful only for non-DFA matching, as
+pcre2_dfa_match() does not support capturing, so no captures are ever
+shown.
+

+

+The normal callout output, showing the callout number or pattern offset (as
+described above) is suppressed if the callout_no_where modifier is set.
+

+

+When using the interpretive matching function pcre2_match() without JIT,
+setting the callout_extra modifier causes additional output from
+pcre2test's callout function to be generated. For the first callout in a
+match attempt at a new starting position in the subject, "New match attempt" is
+output. If there has been a backtrack since the last callout (or start of
+matching if this is the first callout), "Backtrack" is output, followed by "No
+other matching paths" if the backtrack ended the previous match attempt. For
+example:
+
+   re> /(a+)b/auto_callout,no_start_optimize,no_auto_possess
+  data> aac\=callout_extra
+  New match attempt
+  --->aac
+   +0 ^       (
+   +1 ^       a+
+   +3 ^ ^     )
+   +4 ^ ^     b
+  Backtrack
+  --->aac
+   +3 ^^      )
+   +4 ^^      b
+  Backtrack
+  No other matching paths
+  New match attempt
+  --->aac
+   +0  ^      (
+   +1  ^      a+
+   +3  ^^     )
+   +4  ^^     b
+  Backtrack
+  No other matching paths
+  New match attempt
+  --->aac
+   +0   ^     (
+   +1   ^     a+
+  Backtrack
+  No other matching paths
+  New match attempt
+  --->aac
+   +0    ^    (
+   +1    ^    a+
+  No match
+

+Notice that various optimizations must be turned off if you want all possible
+matching paths to be scanned. If no_start_optimize is not used, there is
+an immediate "no match", without any callouts, because the starting
+optimization fails to find "b" in the subject, which it knows must be present
+for any match. If no_auto_possess is not used, the "a+" item is turned
+into "a++", which reduces the number of backtracks.
+

+

+The callout_extra modifier has no effect if used with the DFA matching
+function, or with JIT.
+

+

+Return values from callouts
+

+

+The default return from the callout function is zero, which allows matching to
+continue. The callout_fail modifier can be given one or two numbers. If
+there is only one number, 1 is returned instead of 0 (causing matching to
+backtrack) when a callout of that number is reached. If two numbers (<n>:<m>)
+are given, 1 is returned when callout <n> is reached and there have been at
+least <m> callouts. The callout_error modifier is similar, except that
+PCRE2_ERROR_CALLOUT is returned, causing the entire matching process to be
+aborted. If both these modifiers are set for the same callout number,
+callout_error takes precedence. Note that callouts with string arguments
+are always given the number zero.
+

+

+The callout_data modifier can be given an unsigned or a negative number.
+This is set as the "user data" that is passed to the matching function, and
+passed back when the callout function is invoked. Any value other than zero is
+used as a return from pcre2test's callout function.
+

+

+Inserting callouts can be helpful when using pcre2test to check
+complicated regular expressions. For further information about callouts, see
+the
+pcre2callout
+documentation.
+

+
NON-PRINTING CHARACTERS

+

+When pcre2test is outputting text in the compiled version of a pattern,
+bytes other than 32-126 are always treated as non-printing characters and are
+therefore shown as hex escapes.
+

+

+When pcre2test is outputting text that is a matched part of a subject
+string, it behaves in the same way, unless a different locale has been set for
+the pattern (using the locale modifier). In this case, the
+isprint() function is used to distinguish printing and non-printing
+characters.
+

+
SAVING AND RESTORING COMPILED PATTERNS

+

+It is possible to save compiled patterns on disc or elsewhere, and reload them
+later, subject to a number of restrictions. JIT data cannot be saved. The host
+on which the patterns are reloaded must be running the same version of PCRE2,
+with the same code unit width, and must also have the same endianness, pointer
+width and PCRE2_SIZE type. Before compiled patterns can be saved they must be
+serialized, that is, converted to a stream of bytes. A single byte stream may
+contain any number of compiled patterns, but they must all use the same
+character tables. A single copy of the tables is included in the byte stream
+(its size is 1088 bytes).
+

+

+The functions whose names begin with pcre2_serialize_ are used
+for serializing and de-serializing. They are described in the
+pcre2serialize
+documentation. In this section we describe the features of pcre2test that
+can be used to test these functions.
+

+

+Note that "serialization" in PCRE2 does not convert compiled patterns to an
+abstract format like Java or .NET. It just makes a reloadable byte code stream.
+Hence the restrictions on reloading mentioned above.
+

+

+In pcre2test, when a pattern with push modifier is successfully
+compiled, it is pushed onto a stack of compiled patterns, and pcre2test
+expects the next line to contain a new pattern (or command) instead of a
+subject line. By contrast, the pushcopy modifier causes a copy of the
+compiled pattern to be stacked, leaving the original available for immediate
+matching. By using push and/or pushcopy, a number of patterns can
+be compiled and retained. These modifiers are incompatible with posix,
+and control modifiers that act at match time are ignored (with a message) for
+the stacked patterns. The jitverify modifier applies only at compile
+time.
+

+

+The command
+
+  #save <filename>
+

+causes all the stacked patterns to be serialized and the result written to the
+named file. Afterwards, all the stacked patterns are freed. The command
+
+  #load <filename>
+

+reads the data in the file, and then arranges for it to be de-serialized, with
+the resulting compiled patterns added to the pattern stack. The pattern on the
+top of the stack can be retrieved by the #pop command, which must be followed
+by lines of subjects that are to be matched with the pattern, terminated as
+usual by an empty line or end of file. This command may be followed by a
+modifier list containing only
+control modifiers
+that act after a pattern has been compiled. In particular, hex,
+posix, posix_nosub, push, and pushcopy are not allowed,
+nor are any
+option-setting modifiers.
+The JIT modifiers are, however permitted. Here is an example that saves and
+reloads two patterns.
+
+  /abc/push
+  /xyz/push
+  #save tempfile
+  #load tempfile
+  #pop info
+  xyz
+
+  #pop jit,bincode
+  abc
+

+If jitverify is used with #pop, it does not automatically imply
+jit, which is different behaviour from when it is used on a pattern.
+

+

+The #popcopy command is analogous to the pushcopy modifier in that it
+makes current a copy of the topmost stack pattern, leaving the original still
+on the stack.

+

+UNICODE AND UTF SUPPORT
+

+

+PCRE2 is normally built with Unicode support, though if you do not need it, you
+can build it without, in which case the library will be smaller. With Unicode
+support, PCRE2 has knowledge of Unicode character properties and can process
+strings of text in UTF-8, UTF-16, and UTF-32 format (depending on the code unit
+width), but this is not the default. Unless specifically requested, PCRE2
+treats each code unit in a string as one character.
+

+

+There are two ways of telling PCRE2 to switch to UTF mode, where characters may
+consist of more than one code unit and the range of values is constrained. The
+program can call
+pcre2_compile()
+with the PCRE2_UTF option, or the pattern may start with the sequence (*UTF).
+However, the latter facility can be locked out by the PCRE2_NEVER_UTF option.
+That is, the programmer can prevent the supplier of the pattern from switching
+to UTF mode.
+

+

+Note that the PCRE2_MATCH_INVALID_UTF option (see
+below)
+forces PCRE2_UTF to be set.
+

+

+In UTF mode, both the pattern and any subject strings that are matched against
+it are treated as UTF strings instead of strings of individual one-code-unit
+characters. There are also some other changes to the way characters are
+handled, as documented below.
+

+

+UNICODE PROPERTY SUPPORT
+

+

+When PCRE2 is built with Unicode support, the escape sequences \p{..},
+\P{..}, and \X can be used. This is not dependent on the PCRE2_UTF setting.
+The Unicode properties that can be tested are a subset of those that Perl
+supports. Currently they are limited to the general category properties such as
+Lu for an upper case letter or Nd for a decimal number, the derived properties
+Any and LC (synonym L&), the Unicode script names such as Arabic or Han,
+Bidi_Class, Bidi_Control, and a few binary properties.
+

+

+The full lists are given in the
+pcre2pattern
+and
+pcre2syntax
+documentation. In general, only the short names for properties are supported.
+For example, \p{L} matches a letter. Its longer synonym, \p{Letter}, is not
+supported. Furthermore, in Perl, many properties may optionally be prefixed by
+"Is", for compatibility with Perl 5.6. PCRE2 does not support this.
+

+

+WIDE CHARACTERS AND UTF MODES
+

+

+Code points less than 256 can be specified in patterns by either braced or
+unbraced hexadecimal escape sequences (for example, \x{b3} or \xb3). Larger
+values have to use braced sequences. Unbraced octal code points up to \777 are
+also recognized; larger ones can be coded using \o{...}.
+

+

+The escape sequence \N{U+<hex digits>} is recognized as another way of
+specifying a Unicode character by code point in a UTF mode. It is not allowed
+in non-UTF mode.
+

+

+In UTF mode, repeat quantifiers apply to complete UTF characters, not to
+individual code units.
+

+

+In UTF mode, the dot metacharacter matches one UTF character instead of a
+single code unit.
+

+

+In UTF mode, capture group names are not restricted to ASCII, and may contain
+any Unicode letters and decimal digits, as well as underscore.
+

+

+The escape sequence \C can be used to match a single code unit in UTF mode,
+but its use can lead to some strange effects because it breaks up multi-unit
+characters (see the description of \C in the
+pcre2pattern
+documentation). For this reason, there is a build-time option that disables
+support for \C completely. There is also a less draconian compile-time option
+for locking out the use of \C when a pattern is compiled.
+

+

+The use of \C is not supported by the alternative matching function
+pcre2_dfa_match() when in UTF-8 or UTF-16 mode, that is, when a character
+may consist of more than one code unit. The use of \C in these modes provokes
+a match-time error. Also, the JIT optimization does not support \C in these
+modes. If JIT optimization is requested for a UTF-8 or UTF-16 pattern that
+contains \C, it will not succeed, and so when pcre2_match() is called,
+the matching will be carried out by the interpretive function.
+

+

+The character escapes \b, \B, \d, \D, \s, \S, \w, and \W correctly test
+characters of any code value, but, by default, the characters that PCRE2
+recognizes as digits, spaces, or word characters remain the same set as in
+non-UTF mode, all with code points less than 256. This remains true even when
+PCRE2 is built to include Unicode support, because to do otherwise would slow
+down matching in many common cases. Note that this also applies to \b
+and \B, because they are defined in terms of \w and \W. If you want
+to test for a wider sense of, say, "digit", you can use explicit Unicode
+property tests such as \p{Nd}. Alternatively, if you set the PCRE2_UCP option,
+the way that the character escapes work is changed so that Unicode properties
+are used to determine which characters match, though there are some options
+that suppress this for individual escapes. For details see the section on
+generic character types
+in the
+pcre2pattern
+documentation.
+

+

+Like the escapes, characters that match the POSIX named character classes are
+all low-valued characters unless the PCRE2_UCP option is set, but there is an
+option to override this.
+

+

+In contrast to the character escapes and character classes, the special
+horizontal and vertical white space escapes (\h, \H, \v, and \V) do match
+all the appropriate Unicode characters, whether or not PCRE2_UCP is set.
+

+

+UNICODE CASE-EQUIVALENCE
+

+

+If either PCRE2_UTF or PCRE2_UCP is set, upper/lower case processing makes use
+of Unicode properties except for characters whose code points are less than 128
+and that have at most two case-equivalent values. For these, a direct table
+lookup is used for speed. A few Unicode characters such as Greek sigma have
+more than two code points that are case-equivalent, and these are treated
+specially. Setting PCRE2_UCP without PCRE2_UTF allows Unicode-style case
+processing for non-UTF character encodings such as UCS-2.
+

+

+There are two ASCII characters (S and K) that, in addition to their ASCII lower
+case equivalents, have a non-ASCII one as well (long S and Kelvin sign).
+Recognition of these non-ASCII characters as case-equivalent to their ASCII
+counterparts can be disabled by setting the PCRE2_EXTRA_CASELESS_RESTRICT
+option. When this is set, all characters in a case equivalence must either be
+ASCII or non-ASCII; there can be no mixing.
+

+

+SCRIPT RUNS
+

+

+The pattern constructs (*script_run:...) and (*atomic_script_run:...), with
+synonyms (*sr:...) and (*asr:...), verify that the string matched within the
+parentheses is a script run. In concept, a script run is a sequence of
+characters that are all from the same Unicode script. However, because some
+scripts are commonly used together, and because some diacritical and other
+marks are used with multiple scripts, it is not that simple.
+

+

+Every Unicode character has a Script property, mostly with a value
+corresponding to the name of a script, such as Latin, Greek, or Cyrillic. There
+are also three special values:
+

+

+"Unknown" is used for code points that have not been assigned, and also for the
+surrogate code points. In the PCRE2 32-bit library, characters whose code
+points are greater than the Unicode maximum (U+10FFFF), which are accessible
+only in non-UTF mode, are assigned the Unknown script.
+

+

+"Common" is used for characters that are used with many scripts. These include
+punctuation, emoji, mathematical, musical, and currency symbols, and the ASCII
+digits 0 to 9.
+

+

+"Inherited" is used for characters such as diacritical marks that modify a
+previous character. These are considered to take on the script of the character
+that they modify.
+

+

+Some Inherited characters are used with many scripts, but many of them are only
+normally used with a small number of scripts. For example, U+102E0 (Coptic
+Epact thousands mark) is used only with Arabic and Coptic. In order to make it
+possible to check this, a Unicode property called Script Extension exists. Its
+value is a list of scripts that apply to the character. For the majority of
+characters, the list contains just one script, the same one as the Script
+property. However, for characters such as U+102E0 more than one Script is
+listed. There are also some Common characters that have a single, non-Common
+script in their Script Extension list.
+

+

+The next section describes the basic rules for deciding whether a given string
+of characters is a script run. Note, however, that there are some special cases
+involving the Chinese Han script, and an additional constraint for decimal
+digits. These are covered in subsequent sections.
+

+

+Basic script run rules
+

+

+A string that is less than two characters long is a script run. This is the
+only case in which an Unknown character can be part of a script run. Longer
+strings are checked using only the Script Extensions property, not the basic
+Script property.
+

+

+If a character's Script Extension property is the single value "Inherited", it
+is always accepted as part of a script run. This is also true for the property
+"Common", subject to the checking of decimal digits described below. All the
+remaining characters in a script run must have at least one script in common in
+their Script Extension lists. In set-theoretic terminology, the intersection of
+all the sets of scripts must not be empty.
+

+

+A simple example is an Internet name such as "google.com". The letters are all
+in the Latin script, and the dot is Common, so this string is a script run.
+However, the Cyrillic letter "o" looks exactly the same as the Latin "o"; a
+string that looks the same, but with Cyrillic "o"s is not a script run.
+

+

+More interesting examples involve characters with more than one script in their
+Script Extension. Consider the following characters:
+
+  U+060C  Arabic comma
+  U+06D4  Arabic full stop
+

+The first has the Script Extension list Arabic, Hanifi Rohingya, Syriac, and
+Thaana; the second has just Arabic and Hanifi Rohingya. Both of them could
+appear in script runs of either Arabic or Hanifi Rohingya. The first could also
+appear in Syriac or Thaana script runs, but the second could not.
+

+

+The Chinese Han script
+

+

+The Chinese Han script is commonly used in conjunction with other scripts for
+writing certain languages. Japanese uses the Hiragana and Katakana scripts
+together with Han; Korean uses Hangul and Han; Taiwanese Mandarin uses Bopomofo
+and Han. These three combinations are treated as special cases when checking
+script runs and are, in effect, "virtual scripts". Thus, a script run may
+contain a mixture of Hiragana, Katakana, and Han, or a mixture of Hangul and
+Han, or a mixture of Bopomofo and Han, but not, for example, a mixture of
+Hangul and Bopomofo and Han. PCRE2 (like Perl) follows Unicode's Technical
+Standard 39 ("Unicode Security Mechanisms", http://unicode.org/reports/tr39/)
+in allowing such mixtures.
+

+

+Decimal digits
+

+

+Unicode contains many sets of 10 decimal digits in different scripts, and some
+scripts (including the Common script) contain more than one set. Some of these
+decimal digits them are visually indistinguishable from the common ASCII
+digits. In addition to the script checking described above, if a script run
+contains any decimal digits, they must all come from the same set of 10
+adjacent characters.
+

+

+VALIDITY OF UTF STRINGS
+

+

+When the PCRE2_UTF option is set, the strings passed as patterns and subjects
+are (by default) checked for validity on entry to the relevant functions. If an
+invalid UTF string is passed, a negative error code is returned. The code unit
+offset to the offending character can be extracted from the match data block by
+calling pcre2_get_startchar(), which is used for this purpose after a UTF
+error.
+

+

+In some situations, you may already know that your strings are valid, and
+therefore want to skip these checks in order to improve performance, for
+example in the case of a long subject string that is being scanned repeatedly.
+If you set the PCRE2_NO_UTF_CHECK option at compile time or at match time,
+PCRE2 assumes that the pattern or subject it is given (respectively) contains
+only valid UTF code unit sequences.
+

+

+If you pass an invalid UTF string when PCRE2_NO_UTF_CHECK is set, the result
+is undefined and your program may crash or loop indefinitely or give incorrect
+results. There is, however, one mode of matching that can handle invalid UTF
+subject strings. This is enabled by passing PCRE2_MATCH_INVALID_UTF to
+pcre2_compile() and is discussed below in the next section. The rest of
+this section covers the case when PCRE2_MATCH_INVALID_UTF is not set.
+

+

+Passing PCRE2_NO_UTF_CHECK to pcre2_compile() just disables the UTF check
+for the pattern; it does not also apply to subject strings. If you want to
+disable the check for a subject string you must pass this same option to
+pcre2_match() or pcre2_dfa_match().
+

+

+UTF-16 and UTF-32 strings can indicate their endianness by special code knows
+as a byte-order mark (BOM). The PCRE2 functions do not handle this, expecting
+strings to be in host byte order.
+

+

+Unless PCRE2_NO_UTF_CHECK is set, a UTF string is checked before any other
+processing takes place. In the case of pcre2_match() and
+pcre2_dfa_match() calls with a non-zero starting offset, the check is
+applied only to that part of the subject that could be inspected during
+matching, and there is a check that the starting offset points to the first
+code unit of a character or to the end of the subject. If there are no
+lookbehind assertions in the pattern, the check starts at the starting offset.
+Otherwise, it starts at the length of the longest lookbehind before the
+starting offset, or at the start of the subject if there are not that many
+characters before the starting offset. Note that the sequences \b and \B are
+one-character lookbehinds.
+

+

+In addition to checking the format of the string, there is a check to ensure
+that all code points lie in the range U+0 to U+10FFFF, excluding the surrogate
+area. The so-called "non-character" code points are not excluded because
+Unicode corrigendum #9 makes it clear that they should not be.
+

+

+Characters in the "Surrogate Area" of Unicode are reserved for use by UTF-16,
+where they are used in pairs to encode code points with values greater than
+0xFFFF. The code points that are encoded by UTF-16 pairs are available
+independently in the UTF-8 and UTF-32 encodings. (In other words, the whole
+surrogate thing is a fudge for UTF-16 which unfortunately messes up UTF-8 and
+UTF-32.)
+

+

+Setting PCRE2_NO_UTF_CHECK at compile time does not disable the error that is
+given if an escape sequence for an invalid Unicode code point is encountered in
+the pattern. If you want to allow escape sequences such as \x{d800} (a
+surrogate code point) you can set the PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES extra
+option. However, this is possible only in UTF-8 and UTF-32 modes, because these
+values are not representable in UTF-16.
+

+

+Errors in UTF-8 strings
+

+

+The following negative error codes are given for invalid UTF-8 strings:
+
+  PCRE2_ERROR_UTF8_ERR1
+  PCRE2_ERROR_UTF8_ERR2
+  PCRE2_ERROR_UTF8_ERR3
+  PCRE2_ERROR_UTF8_ERR4
+  PCRE2_ERROR_UTF8_ERR5
+

+The string ends with a truncated UTF-8 character; the code specifies how many
+bytes are missing (1 to 5). Although RFC 3629 restricts UTF-8 characters to be
+no longer than 4 bytes, the encoding scheme (originally defined by RFC 2279)
+allows for up to 6 bytes, and this is checked first; hence the possibility of
+4 or 5 missing bytes.
+
+  PCRE2_ERROR_UTF8_ERR6
+  PCRE2_ERROR_UTF8_ERR7
+  PCRE2_ERROR_UTF8_ERR8
+  PCRE2_ERROR_UTF8_ERR9
+  PCRE2_ERROR_UTF8_ERR10
+

+The two most significant bits of the 2nd, 3rd, 4th, 5th, or 6th byte of the
+character do not have the binary value 0b10 (that is, either the most
+significant bit is 0, or the next bit is 1).
+
+  PCRE2_ERROR_UTF8_ERR11
+  PCRE2_ERROR_UTF8_ERR12
+

+A character that is valid by the RFC 2279 rules is either 5 or 6 bytes long;
+these code points are excluded by RFC 3629.
+
+  PCRE2_ERROR_UTF8_ERR13
+

+A 4-byte character has a value greater than 0x10ffff; these code points are
+excluded by RFC 3629.
+
+  PCRE2_ERROR_UTF8_ERR14
+

+A 3-byte character has a value in the range 0xd800 to 0xdfff; this range of
+code points are reserved by RFC 3629 for use with UTF-16, and so are excluded
+from UTF-8.
+
+  PCRE2_ERROR_UTF8_ERR15
+  PCRE2_ERROR_UTF8_ERR16
+  PCRE2_ERROR_UTF8_ERR17
+  PCRE2_ERROR_UTF8_ERR18
+  PCRE2_ERROR_UTF8_ERR19
+

+A 2-, 3-, 4-, 5-, or 6-byte character is "overlong", that is, it codes for a
+value that can be represented by fewer bytes, which is invalid. For example,
+the two bytes 0xc0, 0xae give the value 0x2e, whose correct coding uses just
+one byte.
+
+  PCRE2_ERROR_UTF8_ERR20
+

+The two most significant bits of the first byte of a character have the binary
+value 0b10 (that is, the most significant bit is 1 and the second is 0). Such a
+byte can only validly occur as the second or subsequent byte of a multi-byte
+character.
+
+  PCRE2_ERROR_UTF8_ERR21
+

+The first byte of a character has the value 0xfe or 0xff. These values can
+never occur in a valid UTF-8 string.
+

+

+Errors in UTF-16 strings
+

+

+The following negative error codes are given for invalid UTF-16 strings:
+
+  PCRE2_ERROR_UTF16_ERR1  Missing low surrogate at end of string
+  PCRE2_ERROR_UTF16_ERR2  Invalid low surrogate follows high surrogate
+  PCRE2_ERROR_UTF16_ERR3  Isolated low surrogate
+
+

+

+

+Errors in UTF-32 strings
+

+

+The following negative error codes are given for invalid UTF-32 strings:
+
+  PCRE2_ERROR_UTF32_ERR1  Surrogate character (0xd800 to 0xdfff)
+  PCRE2_ERROR_UTF32_ERR2  Code point is greater than 0x10ffff
+
+

+

+

+MATCHING IN INVALID UTF STRINGS
+

+

+You can run pattern matches on subject strings that may contain invalid UTF
+sequences if you call pcre2_compile() with the PCRE2_MATCH_INVALID_UTF
+option. This is supported by pcre2_match(), including JIT matching, but
+not by pcre2_dfa_match(). When PCRE2_MATCH_INVALID_UTF is set, it forces
+PCRE2_UTF to be set as well. Note, however, that the pattern itself must be a
+valid UTF string.
+

+

+If you do not set PCRE2_MATCH_INVALID_UTF when calling pcre2_compile, and
+you are not certain that your subject strings are valid UTF sequences, you
+should not make use of the JIT "fast path" function pcre2_jit_match()
+because it bypasses sanity checks, including the one for UTF validity. An
+invalid string may cause undefined behaviour, including looping, crashing, or
+giving the wrong answer.
+

+

+Setting PCRE2_MATCH_INVALID_UTF does not affect what pcre2_compile()
+generates, but if pcre2_jit_compile() is subsequently called, it does
+generate different code. If JIT is not used, the option affects the behaviour
+of the interpretive code in pcre2_match(). When PCRE2_MATCH_INVALID_UTF
+is set at compile time, PCRE2_NO_UTF_CHECK is ignored at match time.
+

+

+In this mode, an invalid code unit sequence in the subject never matches any
+pattern item. It does not match dot, it does not match \p{Any}, it does not
+even match negative items such as [^X]. A lookbehind assertion fails if it
+encounters an invalid sequence while moving the current point backwards. In
+other words, an invalid UTF code unit sequence acts as a barrier which no match
+can cross.
+

+

+You can also think of this as the subject being split up into fragments of
+valid UTF, delimited internally by invalid code unit sequences. The pattern is
+matched fragment by fragment. The result of a successful match, however, is
+given as code unit offsets in the entire subject string in the usual way. There
+are a few points to consider:
+

+

+The internal boundaries are not interpreted as the beginnings or ends of lines
+and so do not match circumflex or dollar characters in the pattern.
+

+

+If pcre2_match() is called with an offset that points to an invalid
+UTF-sequence, that sequence is skipped, and the match starts at the next valid
+UTF character, or the end of the subject.
+

+

+At internal fragment boundaries, \b and \B behave in the same way as at the
+beginning and end of the subject. For example, a sequence such as \bWORD\b
+would match an instance of WORD that is surrounded by invalid UTF code units.
+

+

+Using PCRE2_MATCH_INVALID_UTF, an application can run matches on arbitrary
+data, knowing that any matched strings that are returned are valid UTF. This
+can be useful when searching for UTF text in executable or other binary files.
+

+

+Note, however, that the 16-bit and 32-bit PCRE2 libraries process strings as
+sequences of uint16_t or uint32_t code points. They cannot find valid UTF
+sequences within an arbitrary string of bytes unless such sequences are
+suitably aligned.

+.TH PCRE2 3 "27 August 2021" "PCRE2 10.38"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH INTRODUCTION
+.rs
+.sp
+PCRE2 is the name used for a revised API for the PCRE library, which is a set
+of functions, written in C, that implement regular expression pattern matching
+using the same syntax and semantics as Perl, with just a few differences. After
+nearly two decades, the limitations of the original API were making development
+increasingly difficult. The new API is more extensible, and it was simplified
+by abolishing the separate "study" optimizing function; in PCRE2, patterns are
+automatically optimized where possible. Since forking from PCRE1, the code has
+been extensively refactored and new features introduced. The old library is now
+obsolete and is no longer maintained.
+.P
+As well as Perl-style regular expression patterns, some features that appeared
+in Python and the original PCRE before they appeared in Perl are available
+using the Python syntax. There is also some support for one or two .NET and
+Oniguruma syntax items, and there are options for requesting some minor changes
+that give better ECMAScript (aka JavaScript) compatibility.
+.P
+The source code for PCRE2 can be compiled to support strings of 8-bit, 16-bit,
+or 32-bit code units, which means that up to three separate libraries may be
+installed, one for each code unit size. The size of code unit is not related to
+the bit size of the underlying hardware. In a 64-bit environment that also
+supports 32-bit applications, versions of PCRE2 that are compiled in both
+64-bit and 32-bit modes may be needed.
+.P
+The original work to extend PCRE to 16-bit and 32-bit code units was done by
+Zoltan Herczeg and Christian Persch, respectively. In all three cases, strings
+can be interpreted either as one character per code unit, or as UTF-encoded
+Unicode, with support for Unicode general category properties. Unicode support
+is optional at build time (but is the default). However, processing strings as
+UTF code units must be enabled explicitly at run time. The version of Unicode
+in use can be discovered by running
+.sp
+  pcre2test -C
+.P
+The three libraries contain identical sets of functions, with names ending in
+_8, _16, or _32, respectively (for example, \fBpcre2_compile_8()\fP). However,
+by defining PCRE2_CODE_UNIT_WIDTH to be 8, 16, or 32, a program that uses just
+one code unit width can be written using generic names such as
+\fBpcre2_compile()\fP, and the documentation is written assuming that this is
+the case.
+.P
+In addition to the Perl-compatible matching function, PCRE2 contains an
+alternative function that matches the same compiled patterns in a different
+way. In certain circumstances, the alternative function has some advantages.
+For a discussion of the two matching algorithms, see the
+.\" HREF
+\fBpcre2matching\fP

+page.

+Details of exactly which Perl regular expression features are and are not
+supported by PCRE2 are given in separate documents. See the
+.\" HREF

+and
+.\" HREF
+\fBpcre2compat\fP
+.\"
+pages. There is a syntax summary in the
+.\" HREF
+\fBpcre2syntax\fP
+.\"
+page.
+.P
+Some features of PCRE2 can be included, excluded, or changed when the library
+is built. The
+.\" HREF
+\fBpcre2_config()\fP
+.\"
+function makes it possible for a client to discover which features are
+available. The features themselves are described in the
+.\" HREF
+\fBpcre2build\fP

+found in the

+files in the source distribution.

+The libraries contains a number of undocumented internal functions and data
+tables that are used by more than one of the exported external functions, but
+which are not intended for use by external callers. Their names all begin with
+"_pcre2", which hopefully will not provoke any name clashes. In some
+environments, it is possible to control which external symbols are exported
+when a shared library is built, and in these cases the undocumented symbols are
+not exported.
+.
+.
+.SH "SECURITY CONSIDERATIONS"
+.rs
+.sp
+If you are using PCRE2 in a non-UTF application that permits users to supply
+arbitrary patterns for compilation, you should be aware of a feature that
+allows users to turn on UTF support from within a pattern. For example, an
+8-bit pattern that begins with "(*UTF)" turns on UTF-8 mode, which interprets
+patterns and subjects as strings of UTF-8 code units instead of individual
+8-bit characters. This causes both the pattern and any data against which it is
+matched to be checked for UTF-8 validity. If the data string is very long, such
+a check might use sufficiently many resources as to cause your application to
+lose performance.
+.P
+One way of guarding against this possibility is to use the
+\fBpcre2_pattern_info()\fP function to check the compiled pattern's options for
+PCRE2_UTF. Alternatively, you can set the PCRE2_NEVER_UTF option when calling
+\fBpcre2_compile()\fP. This causes a compile time error if the pattern contains
+a UTF-setting sequence.
+.P
+The use of Unicode properties for character types such as \ed can also be
+enabled from within the pattern, by specifying "(*UCP)". This feature can be
+disallowed by setting the PCRE2_NEVER_UCP option.
+.P
+If your application is one that supports UTF, be aware that validity checking
+can take time. If the same data string is to be matched many times, you can use
+the PCRE2_NO_UTF_CHECK option for the second and subsequent matches to avoid
+running redundant checks.
+.P
+The use of the \eC escape sequence in a UTF-8 or UTF-16 pattern can lead to
+problems, because it may leave the current matching point in the middle of a
+multi-code-unit character. The PCRE2_NEVER_BACKSLASH_C option can be used by an
+application to lock out the use of \eC, causing a compile-time error if it is
+encountered. It is also possible to build PCRE2 with the use of \eC permanently
+disabled.
+.P
+Another way that performance can be hit is by running a pattern that has a very
+large search tree against a string that will never match. Nested unlimited
+repeats in a pattern are a common example. PCRE2 provides some protection
+against this: see the \fBpcre2_set_match_limit()\fP function in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+page. There is a similar function called \fBpcre2_set_depth_limit()\fP that can
+be used to restrict the amount of memory that is used.
+.
+.
+.SH "USER DOCUMENTATION"
+.rs
+.sp
+The user documentation for PCRE2 comprises a number of different sections. In
+the "man" format, each of these is a separate "man page". In the HTML format,

+NAME
+       PCRE2 - Perl-compatible regular expressions (revised API)
+
+
+INTRODUCTION
+
+       PCRE2 is the name used for a revised API for the PCRE library, which is
+       a  set  of  functions,  written in C, that implement regular expression
+       pattern matching using the same syntax and semantics as Perl, with just
+       a few differences. After nearly two decades,  the  limitations  of  the
+       original  API  were  making development increasingly difficult. The new
+       API is more extensible, and it was simplified by abolishing  the  sepa-
+       rate  "study" optimizing function; in PCRE2, patterns are automatically
+       optimized where possible. Since forking from PCRE1, the code  has  been
+       extensively  refactored and new features introduced. The old library is
+       now obsolete and is no longer maintained.
+
+       As well as Perl-style regular expression patterns, some  features  that
+       appeared  in  Python and the original PCRE before they appeared in Perl
+       are available using the Python syntax. There is also some  support  for
+       one  or  two .NET and Oniguruma syntax items, and there are options for
+       requesting  some  minor  changes  that  give  better  ECMAScript   (aka
+       JavaScript) compatibility.
+
+       The  source code for PCRE2 can be compiled to support strings of 8-bit,
+       16-bit, or 32-bit code units, which means that up to three separate li-
+       braries may be installed, one for each code unit size. The size of code
+       unit is not related to the bit size of the underlying  hardware.  In  a
+       64-bit  environment that also supports 32-bit applications, versions of
+       PCRE2 that are compiled in both 64-bit and 32-bit modes may be needed.
+
+       The original work to extend PCRE to 16-bit and 32-bit  code  units  was
+       done by Zoltan Herczeg and Christian Persch, respectively. In all three
+       cases,  strings  can  be  interpreted  either as one character per code
+       unit, or as UTF-encoded Unicode, with support for Unicode general cate-
+       gory properties. Unicode support is optional at build time (but is  the
+       default). However, processing strings as UTF code units must be enabled
+       explicitly at run time. The version of Unicode in use can be discovered
+       by running
+
+         pcre2test -C
+
+       The  three  libraries  contain  identical sets of functions, with names
+       ending in _8,  _16,  or  _32,  respectively  (for  example,  pcre2_com-
+       pile_8()).  However,  by defining PCRE2_CODE_UNIT_WIDTH to be 8, 16, or
+       32, a program that uses just one code unit width can be  written  using
+       generic names such as pcre2_compile(), and the documentation is written
+       assuming that this is the case.
+
+       In addition to the Perl-compatible matching function, PCRE2 contains an
+       alternative  function that matches the same compiled patterns in a dif-
+       ferent way. In certain circumstances, the alternative function has some
+       advantages.  For a discussion of the two matching algorithms,  see  the
+       pcre2matching page.
+
+       Details  of  exactly which Perl regular expression features are and are
+       not supported by  PCRE2  are  given  in  separate  documents.  See  the
+       pcre2pattern  and  pcre2compat  pages. There is a syntax summary in the
+       pcre2syntax page.
+
+       Some features of PCRE2 can be included, excluded, or changed  when  the
+       library  is  built. The pcre2_config() function makes it possible for a
+       client to discover which features are  available.  The  features  them-
+       selves are described in the pcre2build page. Documentation about build-
+       ing  PCRE2 for various operating systems can be found in the README and
+       NON-AUTOTOOLS_BUILD files in the source distribution.
+
+       The libraries contains a number of undocumented internal functions  and
+       data  tables  that  are  used by more than one of the exported external
+       functions, but which are not intended  for  use  by  external  callers.
+       Their  names  all begin with "_pcre2", which hopefully will not provoke
+       any name clashes. In some environments, it is possible to control which
+       external symbols are exported when a shared library is  built,  and  in
+       these cases the undocumented symbols are not exported.
+
+
+SECURITY CONSIDERATIONS
+
+       If  you  are using PCRE2 in a non-UTF application that permits users to
+       supply arbitrary patterns for compilation, you should  be  aware  of  a
+       feature that allows users to turn on UTF support from within a pattern.
+       For  example, an 8-bit pattern that begins with "(*UTF)" turns on UTF-8
+       mode, which interprets patterns and subjects as strings of  UTF-8  code
+       units instead of individual 8-bit characters. This causes both the pat-
+       tern  and  any data against which it is matched to be checked for UTF-8
+       validity. If the data string is very long, such a check might use  suf-
+       ficiently  many  resources as to cause your application to lose perfor-
+       mance.
+
+       One way of guarding against this possibility is to use  the  pcre2_pat-
+       tern_info()  function  to  check  the  compiled  pattern's  options for
+       PCRE2_UTF. Alternatively, you can set the PCRE2_NEVER_UTF  option  when
+       calling  pcre2_compile().  This causes a compile time error if the pat-
+       tern contains a UTF-setting sequence.
+
+       The use of Unicode properties for character types such as \d  can  also
+       be  enabled  from within the pattern, by specifying "(*UCP)". This fea-
+       ture can be disallowed by setting the PCRE2_NEVER_UCP option.
+
+       If your application is one that supports UTF, be  aware  that  validity
+       checking  can  take time. If the same data string is to be matched many
+       times, you can use the PCRE2_NO_UTF_CHECK option  for  the  second  and
+       subsequent matches to avoid running redundant checks.
+
+       The use of the \C escape sequence in a UTF-8 or UTF-16 pattern can lead
+       to  problems,  because  it  may leave the current matching point in the
+       middle of a multi-code-unit character. The PCRE2_NEVER_BACKSLASH_C  op-
+       tion can be used by an application to lock out the use of \C, causing a
+       compile-time  error  if it is encountered. It is also possible to build
+       PCRE2 with the use of \C permanently disabled.
+
+       Another way that performance can be hit is by running  a  pattern  that
+       has  a  very  large search tree against a string that will never match.
+       Nested unlimited repeats in a pattern are a common example. PCRE2  pro-
+       vides  some  protection  against  this: see the pcre2_set_match_limit()
+       function in the pcre2api page.  There  is  a  similar  function  called
+       pcre2_set_depth_limit() that can be used to restrict the amount of mem-
+       ory that is used.
+
+
+USER DOCUMENTATION
+
+       The  user  documentation for PCRE2 comprises a number of different sec-
+       tions. In the "man" format, each of these is a separate "man page".  In
+       the  HTML  format, each is a separate page, linked from the index page.
+       In the plain  text  format,  the  descriptions  of  the  pcre2grep  and

+       respectively.  The remaining sections, except for the pcre2demo section

+
+       These  functions  provide  a  way of converting non-PCRE2 patterns into
+       patterns that can be processed by pcre2_compile(). This facility is ex-
+       perimental and may be changed in future releases. At  present,  "globs"
+       and  POSIX  basic  and  extended patterns can be converted. Details are
+       given in the pcre2convert documentation.
+
+
+PCRE2 8-BIT, 16-BIT, AND 32-BIT LIBRARIES
+
+       There are three PCRE2 libraries, supporting 8-bit, 16-bit,  and  32-bit
+       code  units,  respectively.  However,  there  is  just one header file,
+       pcre2.h.  This contains the function prototypes and  other  definitions
+       for all three libraries. One, two, or all three can be installed simul-
+       taneously.  On  Unix-like  systems the libraries are called libpcre2-8,
+       libpcre2-16, and libpcre2-32, and they can also co-exist with the orig-
+       inal PCRE libraries.  Every PCRE2 function  comes  in  three  different
+       forms, one for each library, for example:
+
+         pcre2_compile_8()
+         pcre2_compile_16()
+         pcre2_compile_32()
+
+       There are also three different sets of data types:
+
+         PCRE2_UCHAR8, PCRE2_UCHAR16, PCRE2_UCHAR32
+         PCRE2_SPTR8,  PCRE2_SPTR16,  PCRE2_SPTR32
+
+       The  UCHAR  types define unsigned code units of the appropriate widths.
+       For example, PCRE2_UCHAR16 is usually defined as `uint16_t'.  The  SPTR
+       types are pointers to constants of the equivalent UCHAR types, that is,
+       they are pointers to vectors of unsigned code units.
+
+       Character  strings  are  passed  to a PCRE2 library as sequences of un-
+       signed integers in code units of the appropriate width. The length of a
+       string may be given as a number of code units, or  the  string  may  be
+       specified as zero-terminated.
+
+       Many  applications use only one code unit width. For their convenience,
+       macros are defined whose names are the generic forms such as pcre2_com-
+       pile() and  PCRE2_SPTR.  These  macros  use  the  value  of  the  macro
+       PCRE2_CODE_UNIT_WIDTH  to generate the appropriate width-specific func-
+       tion and macro names.  PCRE2_CODE_UNIT_WIDTH is not defined by default.
+       An application must define it to be  8,  16,  or  32  before  including
+       pcre2.h in order to make use of the generic names.
+
+       Applications  that use more than one code unit width can be linked with
+       more than one PCRE2 library, but must define  PCRE2_CODE_UNIT_WIDTH  to
+       be  0  before  including pcre2.h, and then use the real function names.
+       Any code that is to be included in an environment where  the  value  of
+       PCRE2_CODE_UNIT_WIDTH  is  unknown  should  also  use the real function
+       names. (Unfortunately, it is not possible in C code to save and restore
+       the value of a macro.)
+
+       If PCRE2_CODE_UNIT_WIDTH is not defined  before  including  pcre2.h,  a
+       compiler error occurs.
+
+       When  using  multiple  libraries  in an application, you must take care
+       when processing any particular pattern to use  only  functions  from  a
+       single  library.   For example, if you want to run a match using a pat-
+       tern that was compiled with pcre2_compile_16(), you  must  do  so  with
+       pcre2_match_16(), not pcre2_match_8() or pcre2_match_32().
+
+       In  the  function summaries above, and in the rest of this document and
+       other PCRE2 documents, functions and data  types  are  described  using
+       their generic names, without the _8, _16, or _32 suffix.
+
+
+PCRE2 API OVERVIEW
+
+       PCRE2  has  its  own  native  API, which is described in this document.
+       There are also some wrapper functions for the 8-bit library that corre-
+       spond to the POSIX regular expression API, but they do not give  access
+       to  all  the  functionality of PCRE2 and they are not thread-safe. They
+       are described in the pcre2posix documentation. Both these APIs define a
+       set of C function calls.
+
+       The native API C data types, function prototypes,  option  values,  and
+       error codes are defined in the header file pcre2.h, which also contains
+       definitions of PCRE2_MAJOR and PCRE2_MINOR, the major and minor release
+       numbers  for the library. Applications can use these to include support
+       for different releases of PCRE2.
+
+       In a Windows environment, if you want to statically link an application
+       program against a non-dll PCRE2 library, you must  define  PCRE2_STATIC
+       before including pcre2.h.
+
+       The  functions pcre2_compile() and pcre2_match() are used for compiling
+       and matching regular expressions in a Perl-compatible manner. A  sample
+       program that demonstrates the simplest way of using them is provided in
+       the file called pcre2demo.c in the PCRE2 source distribution. A listing
+       of  this  program  is  given  in  the  pcre2demo documentation, and the
+       pcre2sample documentation describes how to compile and run it.
+
+       The compiling and matching functions recognize various options that are
+       passed as bits in an options argument. There are also some more compli-
+       cated parameters such as custom memory  management  functions  and  re-
+       source  limits  that  are  passed  in "contexts" (which are just memory
+       blocks, described below). Simple applications do not need to  make  use
+       of contexts.
+
+       Just-in-time  (JIT)  compiler  support  is an optional feature of PCRE2
+       that can be built in  appropriate  hardware  environments.  It  greatly
+       speeds  up  the matching performance of many patterns. Programs can re-
+       quest that it be used if available by calling pcre2_jit_compile() after
+       a pattern has been successfully compiled by pcre2_compile(). This  does
+       nothing if JIT support is not available.
+
+       More  complicated  programs  might  need  to make use of the specialist
+       functions   pcre2_jit_stack_create(),    pcre2_jit_stack_free(),    and
+       pcre2_jit_stack_assign()  in order to control the JIT code's memory us-
+       age.
+
+       JIT matching is automatically used by pcre2_match() if it is available,
+       unless the PCRE2_NO_JIT option is set. There is also a direct interface
+       for JIT matching, which gives improved performance at  the  expense  of
+       less  sanity  checking. The JIT-specific functions are discussed in the
+       pcre2jit documentation.
+
+       A second matching function, pcre2_dfa_match(), which is  not  Perl-com-
+       patible,  is  also  provided.  This  uses a different algorithm for the
+       matching. The alternative algorithm finds all possible  matches  (at  a
+       given  point  in  the subject), and scans the subject just once (unless
+       there are lookaround assertions). However, this algorithm does not  re-
+       turn  captured substrings. A description of the two matching algorithms
+       and their advantages and disadvantages is given  in  the  pcre2matching
+       documentation. There is no JIT support for pcre2_dfa_match().
+
+       In  addition  to  the  main compiling and matching functions, there are
+       convenience functions for extracting captured substrings from a subject
+       string that has been matched by pcre2_match(). They are:
+
+         pcre2_substring_copy_byname()
+         pcre2_substring_copy_bynumber()
+         pcre2_substring_get_byname()
+         pcre2_substring_get_bynumber()
+         pcre2_substring_list_get()
+         pcre2_substring_length_byname()
+         pcre2_substring_length_bynumber()
+         pcre2_substring_nametable_scan()
+         pcre2_substring_number_from_name()
+
+       pcre2_substring_free() and pcre2_substring_list_free()  are  also  pro-
+       vided,  to  free  memory used for extracted strings. If either of these
+       functions is called with a NULL argument, the function returns  immedi-
+       ately without doing anything.
+
+       The  function  pcre2_substitute()  can be called to match a pattern and
+       return a copy of the subject string with substitutions for  parts  that
+       were matched.
+
+       Functions  whose  names begin with pcre2_serialize_ are used for saving
+       compiled patterns on disc or elsewhere, and reloading them later.
+
+       Finally, there are functions for finding out information about  a  com-
+       piled  pattern  (pcre2_pattern_info()) and about the configuration with
+       which PCRE2 was built (pcre2_config()).
+
+       Functions with names ending with _free() are used  for  freeing  memory
+       blocks  of  various  sorts.  In all cases, if one of these functions is
+       called with a NULL argument, it does nothing.
+
+
+STRING LENGTHS AND OFFSETS
+
+       The PCRE2 API uses string lengths and  offsets  into  strings  of  code
+       units  in  several  places. These values are always of type PCRE2_SIZE,
+       which is an unsigned integer type, currently always defined as  size_t.
+       The  largest  value  that  can  be  stored  in  such  a  type  (that is
+       ~(PCRE2_SIZE)0) is reserved as a special indicator for  zero-terminated
+       strings  and  unset offsets.  Therefore, the longest string that can be
+       handled is one less than this maximum. Note that string lengths are al-
+       ways given in code units. Only in the 8-bit library is  such  a  length
+       the same as the number of bytes in the string.
+
+
+NEWLINES
+
+       PCRE2 supports five different conventions for indicating line breaks in
+       strings:  a  single  CR (carriage return) character, a single LF (line-
+       feed) character, the two-character sequence CRLF, any of the three pre-
+       ceding, or any Unicode newline sequence. The Unicode newline  sequences
+       are  the  three just mentioned, plus the single characters VT (vertical
+       tab, U+000B), FF (form feed, U+000C), NEL (next line, U+0085), LS (line
+       separator, U+2028), and PS (paragraph separator, U+2029).
+
+       Each of the first three conventions is used by at least  one  operating
+       system as its standard newline sequence. When PCRE2 is built, a default
+       can be specified.  If it is not, the default is set to LF, which is the
+       Unix standard. However, the newline convention can be changed by an ap-
+       plication  when calling pcre2_compile(), or it can be specified by spe-
+       cial text at the start of the pattern itself; this overrides any  other
+       settings.  See the pcre2pattern page for details of the special charac-
+       ter sequences.
+
+       In the PCRE2 documentation the word "newline"  is  used  to  mean  "the
+       character or pair of characters that indicate a line break". The choice
+       of  newline convention affects the handling of the dot, circumflex, and
+       dollar metacharacters, the handling of #-comments in /x mode, and, when
+       CRLF is a recognized line ending sequence, the match position  advance-
+       ment for a non-anchored pattern. There is more detail about this in the
+       section on pcre2_match() options below.
+
+       The  choice of newline convention does not affect the interpretation of
+       the \n or \r escape sequences, nor does it affect what \R matches; this
+       has its own separate convention.
+
+
+MULTITHREADING
+
+       In a multithreaded application it is important to keep  thread-specific
+       data  separate  from data that can be shared between threads. The PCRE2
+       library code itself is thread-safe: it contains  no  static  or  global
+       variables. The API is designed to be fairly simple for non-threaded ap-
+       plications  while at the same time ensuring that multithreaded applica-
+       tions can use it.
+
+       There are several different blocks of data that are used to pass infor-
+       mation between the application and the PCRE2 libraries.
+
+   The compiled pattern
+
+       A pointer to the compiled form of a pattern is  returned  to  the  user
+       when pcre2_compile() is successful. The data in the compiled pattern is
+       fixed,  and  does not change when the pattern is matched. Therefore, it
+       is thread-safe, that is, the same compiled pattern can be used by  more
+       than one thread simultaneously. For example, an application can compile
+       all its patterns at the start, before forking off multiple threads that
+       use  them.  However,  if the just-in-time (JIT) optimization feature is
+       being used, it needs separate memory stack areas for each  thread.  See
+       the pcre2jit documentation for more details.
+
+       In  a more complicated situation, where patterns are compiled only when
+       they are first needed, but are still shared between  threads,  pointers
+       to  compiled  patterns  must  be protected from simultaneous writing by
+       multiple threads. This is somewhat tricky to do correctly. If you  know
+       that  writing  to  a pointer is atomic in your environment, you can use
+       logic like this:
+
+         Get a read-only (shared) lock (mutex) for pointer
+         if (pointer == NULL)
+           {
+           Get a write (unique) lock for pointer
+           if (pointer == NULL) pointer = pcre2_compile(...
+           }
+         Release the lock
+         Use pointer in pcre2_match()
+
+       Of course, testing for compilation errors should also  be  included  in
+       the code.
+
+       The  reason  for checking the pointer a second time is as follows: Sev-
+       eral threads may have acquired the shared lock and tested  the  pointer
+       for being NULL, but only one of them will be given the write lock, with
+       the  rest kept waiting. The winning thread will compile the pattern and
+       store the result.  After this thread releases the write  lock,  another
+       thread  will  get it, and if it does not retest pointer for being NULL,
+       will recompile the pattern and overwrite the pointer, creating a memory
+       leak and possibly causing other issues.
+
+       In an environment where writing to a pointer may  not  be  atomic,  the
+       above  logic  is not sufficient. The thread that is doing the compiling
+       may be descheduled after writing only part of the pointer, which  could
+       cause  other  threads  to use an invalid value. Instead of checking the
+       pointer itself, a separate "pointer is valid" flag (that can be updated
+       atomically) must be used:
+
+         Get a read-only (shared) lock (mutex) for pointer
+         if (!pointer_is_valid)
+           {
+           Get a write (unique) lock for pointer
+           if (!pointer_is_valid)
+             {
+             pointer = pcre2_compile(...
+             pointer_is_valid = TRUE
+             }
+           }
+         Release the lock
+         Use pointer in pcre2_match()
+
+       If JIT is being used, but the JIT compilation is not being done immedi-
+       ately (perhaps waiting to see if the pattern  is  used  often  enough),
+       similar  logic  is required. JIT compilation updates a value within the
+       compiled code block, so a thread must gain unique write access  to  the
+       pointer     before    calling    pcre2_jit_compile().    Alternatively,
+       pcre2_code_copy() or pcre2_code_copy_with_tables() can be used  to  ob-
+       tain  a  private  copy of the compiled code before calling the JIT com-
+       piler.
+
+   Context blocks
+
+       The next main section below introduces the idea of "contexts" in  which
+       PCRE2 functions are called. A context is nothing more than a collection
+       of parameters that control the way PCRE2 operates. Grouping a number of
+       parameters together in a context is a convenient way of passing them to
+       a  PCRE2  function without using lots of arguments. The parameters that
+       are stored in contexts are in some sense  "advanced  features"  of  the
+       API. Many straightforward applications will not need to use contexts.
+
+       In a multithreaded application, if the parameters in a context are val-
+       ues  that  are  never  changed, the same context can be used by all the
+       threads. However, if any thread needs to change any value in a context,
+       it must make its own thread-specific copy.
+
+   Match blocks
+
+       The matching functions need a block of memory for storing  the  results
+       of a match. This includes details of what was matched, as well as addi-
+       tional  information  such as the name of a (*MARK) setting. Each thread
+       must provide its own copy of this memory.
+
+
+PCRE2 CONTEXTS
+
+       Some PCRE2 functions have a lot of parameters, many of which  are  used
+       only  by  specialist  applications,  for example, those that use custom
+       memory management or non-standard character tables.  To  keep  function
+       argument  lists  at a reasonable size, and at the same time to keep the
+       API extensible, "uncommon" parameters are passed to  certain  functions
+       in  a  context instead of directly. A context is just a block of memory
+       that holds the parameter values.  Applications that do not need to  ad-
+       just any of the context parameters can pass NULL when a context pointer
+       is required.
+
+       There  are  three different types of context: a general context that is
+       relevant for several PCRE2 operations, a compile-time  context,  and  a
+       match-time context.
+
+   The general context
+
+       At  present,  this context just contains pointers to (and data for) ex-
+       ternal memory management functions that are called from several  places
+       in  the  PCRE2  library.  The  context  is  named `general' rather than
+       specifically `memory' because in future other fields may be  added.  If
+       you  do not want to supply your own custom memory management functions,
+       you do not need to bother with a general context. A general context  is
+       created by:
+
+       pcre2_general_context *pcre2_general_context_create(
+         void *(*private_malloc)(PCRE2_SIZE, void *),
+         void (*private_free)(void *, void *), void *memory_data);
+
+       The  two  function pointers specify custom memory management functions,
+       whose prototypes are:
+
+         void *private_malloc(PCRE2_SIZE, void *);
+         void  private_free(void *, void *);
+
+       Whenever code in PCRE2 calls these functions, the final argument is the
+       value of memory_data. Either of the first two arguments of the creation
+       function may be NULL, in which case the system memory management  func-
+       tions  malloc()  and free() are used. (This is not currently useful, as
+       there are no other fields in a general context,  but  in  future  there
+       might  be.)  The private_malloc() function is used (if supplied) to ob-
+       tain memory for storing the context, and all three values are saved  as
+       part of the context.
+
+       Whenever  PCRE2  creates a data block of any kind, the block contains a
+       pointer to the free() function that matches the malloc() function  that
+       was  used.  When  the  time  comes  to free the block, this function is
+       called.
+
+       A general context can be copied by calling:
+
+       pcre2_general_context *pcre2_general_context_copy(
+         pcre2_general_context *gcontext);
+
+       The memory used for a general context should be freed by calling:
+
+       void pcre2_general_context_free(pcre2_general_context *gcontext);
+
+       If this function is passed a  NULL  argument,  it  returns  immediately
+       without doing anything.
+
+   The compile context
+
+       A  compile context is required if you want to provide an external func-
+       tion for stack checking during compilation or  to  change  the  default
+       values of any of the following compile-time parameters:
+
+         What \R matches (Unicode newlines or CR, LF, CRLF only)
+         PCRE2's character tables
+         The newline character sequence
+         The compile time nested parentheses limit
+         The maximum length of the pattern string
+         The extra options bits (none set by default)
+
+       A  compile context is also required if you are using custom memory man-
+       agement.  If none of these apply, just pass NULL as the  context  argu-
+       ment of pcre2_compile().
+
+       A  compile context is created, copied, and freed by the following func-
+       tions:
+
+       pcre2_compile_context *pcre2_compile_context_create(
+         pcre2_general_context *gcontext);
+
+       pcre2_compile_context *pcre2_compile_context_copy(
+         pcre2_compile_context *ccontext);
+
+       void pcre2_compile_context_free(pcre2_compile_context *ccontext);
+
+       A compile context is created with default values  for  its  parameters.
+       These can be changed by calling the following functions, which return 0
+       on success, or PCRE2_ERROR_BADDATA if invalid data is detected.
+
+       int pcre2_set_bsr(pcre2_compile_context *ccontext,
+         uint32_t value);
+
+       The  value  must  be PCRE2_BSR_ANYCRLF, to specify that \R matches only
+       CR, LF, or CRLF, or PCRE2_BSR_UNICODE, to specify that \R  matches  any
+       Unicode line ending sequence. The value is used by the JIT compiler and
+       by   the   two   interpreted   matching  functions,  pcre2_match()  and
+       pcre2_dfa_match().
+
+       int pcre2_set_character_tables(pcre2_compile_context *ccontext,
+         const uint8_t *tables);
+
+       The value must be the result of a  call  to  pcre2_maketables(),  whose
+       only argument is a general context. This function builds a set of char-
+       acter tables in the current locale.
+
+       int pcre2_set_compile_extra_options(pcre2_compile_context *ccontext,
+         uint32_t extra_options);
+
+       As  PCRE2  has developed, almost all the 32 option bits that are avail-
+       able in the options argument of pcre2_compile() have been used  up.  To
+       avoid  running  out, the compile context contains a set of extra option
+       bits which are used for some newer, assumed rarer, options. This  func-
+       tion  sets  those bits. It always sets all the bits (either on or off).
+       It does not modify any existing setting. The available options are  de-
+       fined in the section entitled "Extra compile options" below.
+
+       int pcre2_set_max_pattern_length(pcre2_compile_context *ccontext,
+         PCRE2_SIZE value);
+
+       This  sets a maximum length, in code units, for any pattern string that
+       is compiled with this context. If the pattern is longer,  an  error  is
+       generated.   This facility is provided so that applications that accept
+       patterns from external sources can limit their size. The default is the
+       largest number that a PCRE2_SIZE variable can  hold,  which  is  effec-
+       tively unlimited.
+
+       int pcre2_set_max_pattern_compiled_length(
+         pcre2_compile_context *ccontext, PCRE2_SIZE value);
+
+       This  sets  a maximum size, in bytes, for the memory needed to hold the
+       compiled version of a pattern that is compiled with  this  context.  If
+       the  pattern needs more memory, an error is generated. This facility is
+       provided so  that  applications  that  accept  patterns  from  external
+       sources  can  limit  the  amount of memory they use. The default is the
+       largest number that a PCRE2_SIZE variable can  hold,  which  is  effec-
+       tively unlimited.
+
+       int pcre2_set_max_varlookbehind(pcre2_compile_contest *ccontext,
+         uint32_t value);
+
+       This  sets  a  maximum length for the number of characters matched by a
+       variable-length lookbehind assertion. The default is set when PCRE2  is
+       built,  with  the ultimate default being 255, the same as Perl. Lookbe-
+       hind assertions without a bounding length are not supported.
+
+       int pcre2_set_newline(pcre2_compile_context *ccontext,
+         uint32_t value);
+
+       This specifies which characters or character sequences are to be recog-
+       nized as newlines. The value must be one of PCRE2_NEWLINE_CR  (carriage
+       return only), PCRE2_NEWLINE_LF (linefeed only), PCRE2_NEWLINE_CRLF (the
+       two-character  sequence  CR followed by LF), PCRE2_NEWLINE_ANYCRLF (any
+       of the above), PCRE2_NEWLINE_ANY (any  Unicode  newline  sequence),  or
+       PCRE2_NEWLINE_NUL (the NUL character, that is a binary zero).
+
+       A pattern can override the value set in the compile context by starting
+       with a sequence such as (*CRLF). See the pcre2pattern page for details.
+
+       When  a  pattern  is  compiled  with  the  PCRE2_EXTENDED  or PCRE2_EX-
+       TENDED_MORE option, the newline convention affects the  recognition  of
+       the  end  of internal comments starting with #. The value is saved with
+       the compiled pattern for subsequent use by the JIT compiler and by  the
+       two     interpreted     matching     functions,    pcre2_match()    and
+       pcre2_dfa_match().
+
+       int pcre2_set_parens_nest_limit(pcre2_compile_context *ccontext,
+         uint32_t value);
+
+       This parameter adjusts the limit, set  when  PCRE2  is  built  (default
+       250),  on  the  depth  of  parenthesis nesting in a pattern. This limit
+       stops rogue patterns using up too much system  stack  when  being  com-
+       piled.  The limit applies to parentheses of all kinds, not just captur-
+       ing parentheses.
+
+       int pcre2_set_compile_recursion_guard(pcre2_compile_context *ccontext,
+         int (*guard_function)(uint32_t, void *), void *user_data);
+
+       There is at least one application that runs PCRE2 in threads with  very
+       limited  system  stack,  where running out of stack is to be avoided at
+       all costs. The parenthesis limit above cannot take account of how  much
+       stack  is  actually  available during compilation. For a finer control,
+       you can supply a  function  that  is  called  whenever  pcre2_compile()
+       starts  to compile a parenthesized part of a pattern. This function can
+       check the actual stack size (or anything else  that  it  wants  to,  of
+       course).
+
+       The  first  argument to the callout function gives the current depth of
+       nesting, and the second is user data that is set up by the  last  argu-
+       ment   of  pcre2_set_compile_recursion_guard().  The  callout  function
+       should return zero if all is well, or non-zero to force an error.
+
+   The match context
+
+       A match context is required if you want to:
+
+         Set up a callout function
+         Set an offset limit for matching an unanchored pattern
+         Change the limit on the amount of heap used when matching
+         Change the backtracking match limit
+         Change the backtracking depth limit
+         Set custom memory management specifically for the match
+
+       If none of these apply, just pass  NULL  as  the  context  argument  of
+       pcre2_match(), pcre2_dfa_match(), or pcre2_jit_match().
+
+       A  match  context  is created, copied, and freed by the following func-
+       tions:
+
+       pcre2_match_context *pcre2_match_context_create(
+         pcre2_general_context *gcontext);
+
+       pcre2_match_context *pcre2_match_context_copy(
+         pcre2_match_context *mcontext);
+
+       void pcre2_match_context_free(pcre2_match_context *mcontext);
+
+       A match context is created with  default  values  for  its  parameters.
+       These can be changed by calling the following functions, which return 0
+       on success, or PCRE2_ERROR_BADDATA if invalid data is detected.
+
+       int pcre2_set_callout(pcre2_match_context *mcontext,
+         int (*callout_function)(pcre2_callout_block *, void *),
+         void *callout_data);
+
+       This  sets  up a callout function for PCRE2 to call at specified points
+       during a matching operation. Details are given in the pcre2callout doc-
+       umentation.
+
+       int pcre2_set_substitute_callout(pcre2_match_context *mcontext,
+         int (*callout_function)(pcre2_substitute_callout_block *, void *),
+         void *callout_data);
+
+       This sets up a callout function for PCRE2 to call after each  substitu-
+       tion made by pcre2_substitute(). Details are given in the section enti-
+       tled "Creating a new string with substitutions" below.
+
+       int pcre2_set_offset_limit(pcre2_match_context *mcontext,
+         PCRE2_SIZE value);
+
+       The  offset_limit parameter limits how far an unanchored search can ad-
+       vance in the subject string. The  default  value  is  PCRE2_UNSET.  The
+       pcre2_match()  and  pcre2_dfa_match()  functions return PCRE2_ERROR_NO-
+       MATCH if a match with a starting point before or at the given offset is
+       not found. The pcre2_substitute() function makes no more substitutions.
+
+       For example, if the pattern /abc/ is matched against "123abc"  with  an
+       offset  limit  less  than 3, the result is PCRE2_ERROR_NOMATCH. A match
+       can never be  found  if  the  startoffset  argument  of  pcre2_match(),
+       pcre2_dfa_match(),  or  pcre2_substitute()  is  greater than the offset
+       limit set in the match context.
+
+       When using this facility, you must set the  PCRE2_USE_OFFSET_LIMIT  op-
+       tion when calling pcre2_compile() so that when JIT is in use, different
+       code  can  be  compiled. If a match is started with a non-default match
+       limit when PCRE2_USE_OFFSET_LIMIT is not set, an error is generated.
+
+       The offset limit facility can be used to track progress when  searching
+       large  subject  strings or to limit the extent of global substitutions.
+       See also the PCRE2_FIRSTLINE option, which requires a  match  to  start
+       before  or  at  the first newline that follows the start of matching in
+       the subject. If this is set with an offset limit, a match must occur in
+       the first line and also  within  the  offset  limit.  In  other  words,
+       whichever limit comes first is used.
+
+       int pcre2_set_heap_limit(pcre2_match_context *mcontext,
+         uint32_t value);
+
+       The heap_limit parameter specifies, in units of kibibytes (1024 bytes),
+       the  maximum  amount  of heap memory that pcre2_match() may use to hold
+       backtracking information when running an interpretive match. This limit
+       also applies to pcre2_dfa_match(), which may use the heap when process-
+       ing patterns with a lot of nested pattern recursion or  lookarounds  or
+       atomic groups. This limit does not apply to matching with the JIT opti-
+       mization,  which  has  its  own  memory  control  arrangements (see the
+       pcre2jit documentation for more details). If the limit is reached,  the
+       negative  error  code  PCRE2_ERROR_HEAPLIMIT  is  returned. The default
+       limit can be set when PCRE2 is built; if it is not, the default is  set
+       very large and is essentially unlimited.
+
+       A value for the heap limit may also be supplied by an item at the start
+       of a pattern of the form
+
+         (*LIMIT_HEAP=ddd)
+
+       where  ddd  is a decimal number. However, such a setting is ignored un-
+       less ddd is less than the limit set by the caller of pcre2_match()  or,
+       if no such limit is set, less than the default.
+
+       The  pcre2_match() function always needs some heap memory, so setting a
+       value of zero guarantees a "heap limit exceeded" error. Details of  how
+       pcre2_match()  uses  the  heap are given in the pcre2perform documenta-
+       tion.
+
+       For pcre2_dfa_match(), a vector on the system stack is used  when  pro-
+       cessing  pattern recursions, lookarounds, or atomic groups, and only if
+       this is not big enough is heap memory used. In  this  case,  setting  a
+       value of zero disables the use of the heap.
+
+       int pcre2_set_match_limit(pcre2_match_context *mcontext,
+         uint32_t value);
+
+       The match_limit parameter provides a means of preventing PCRE2 from us-
+       ing  up  too many computing resources when processing patterns that are
+       not going to match, but which have a very large number of possibilities
+       in their search trees. The classic  example  is  a  pattern  that  uses
+       nested unlimited repeats.
+
+       There  is an internal counter in pcre2_match() that is incremented each
+       time round its main matching loop. If  this  value  reaches  the  match
+       limit, pcre2_match() returns the negative value PCRE2_ERROR_MATCHLIMIT.
+       This  has  the  effect  of limiting the amount of backtracking that can
+       take place. For patterns that are not anchored, the count restarts from
+       zero for each position in the subject string. This limit  also  applies
+       to pcre2_dfa_match(), though the counting is done in a different way.
+
+       When  pcre2_match()  is  called  with  a  pattern that was successfully
+       processed by pcre2_jit_compile(), the way in which matching is executed
+       is entirely different. However, there is still the possibility of  run-
+       away matching that goes on for a very long time, and so the match_limit
+       value  is  also used in this case (but in a different way) to limit how
+       long the matching can continue.
+
+       The default value for the limit can be set when PCRE2 is built; the de-
+       fault is 10 million, which handles all but the most  extreme  cases.  A
+       value  for the match limit may also be supplied by an item at the start
+       of a pattern of the form
+
+         (*LIMIT_MATCH=ddd)
+
+       where ddd is a decimal number. However, such a setting is  ignored  un-
+       less  ddd  is less than the limit set by the caller of pcre2_match() or
+       pcre2_dfa_match() or, if no such limit is set, less than the default.
+
+       int pcre2_set_depth_limit(pcre2_match_context *mcontext,
+         uint32_t value);
+
+       This  parameter  limits   the   depth   of   nested   backtracking   in
+       pcre2_match().   Each time a nested backtracking point is passed, a new
+       memory frame is used to remember the state of matching at  that  point.
+       Thus,  this  parameter  indirectly  limits the amount of memory that is
+       used in a match. However, because the size of each memory frame depends
+       on the number of capturing parentheses, the actual memory limit  varies
+       from  pattern to pattern. This limit was more useful in versions before
+       10.30, where function recursion was used for backtracking.
+
+       The depth limit is not relevant, and is ignored, when matching is  done
+       using JIT compiled code. However, it is supported by pcre2_dfa_match(),
+       which  uses it to limit the depth of nested internal recursive function
+       calls that implement atomic groups, lookaround assertions, and  pattern
+       recursions. This limits, indirectly, the amount of system stack that is
+       used.  It  was  more useful in versions before 10.32, when stack memory
+       was used for local workspace vectors for recursive function calls. From
+       version 10.32, only local variables are allocated on the stack  and  as
+       each call uses only a few hundred bytes, even a small stack can support
+       quite a lot of recursion.
+
+       If  the depth of internal recursive function calls is great enough, lo-
+       cal workspace vectors are allocated on the heap from version 10.32  on-
+       wards,  so  the  depth  limit also indirectly limits the amount of heap
+       memory that is used. A recursive pattern such as /(.(?2))((?1)|)/, when
+       matched to a very long string using pcre2_dfa_match(), can use a  great
+       deal  of memory. However, it is probably better to limit heap usage di-
+       rectly by calling pcre2_set_heap_limit().
+
+       The default value for the depth limit can be set when PCRE2  is  built;
+       if  it  is not, the default is set to the same value as the default for
+       the  match  limit.   If  the  limit  is  exceeded,   pcre2_match()   or
+       pcre2_dfa_match() returns PCRE2_ERROR_DEPTHLIMIT. A value for the depth
+       limit  may also be supplied by an item at the start of a pattern of the
+       form
+
+         (*LIMIT_DEPTH=ddd)
+
+       where ddd is a decimal number. However, such a setting is  ignored  un-
+       less  ddd  is less than the limit set by the caller of pcre2_match() or
+       pcre2_dfa_match() or, if no such limit is set, less than the default.
+
+
+CHECKING BUILD-TIME OPTIONS
+
+       int pcre2_config(uint32_t what, void *where);
+
+       The function pcre2_config() makes it possible for  a  PCRE2  client  to
+       find  the  value  of  certain  configuration parameters and to discover
+       which optional features have been compiled into the PCRE2 library.  The
+       pcre2build documentation has more details about these features.
+
+       The  first  argument  for pcre2_config() specifies which information is
+       required. The second argument is a pointer to memory into which the in-
+       formation is placed. If NULL is passed, the function returns the amount
+       of memory that is needed for the requested information. For calls  that
+       return  numerical  values, the value is in bytes; when requesting these
+       values, where should point to appropriately aligned memory.  For  calls
+       that  return  strings,  the required length is given in code units, not
+       counting the terminating zero.
+
+       When requesting information, the returned value from pcre2_config()  is
+       non-negative  on success, or the negative error code PCRE2_ERROR_BADOP-
+       TION if the value in the first argument is not recognized. The  follow-
+       ing information is available:
+
+         PCRE2_CONFIG_BSR
+
+       The  output  is a uint32_t integer whose value indicates what character
+       sequences the \R  escape  sequence  matches  by  default.  A  value  of
+       PCRE2_BSR_UNICODE  means  that  \R  matches any Unicode line ending se-
+       quence; a value of PCRE2_BSR_ANYCRLF means that \R matches only CR, LF,
+       or CRLF. The default can be overridden when a pattern is compiled.
+
+         PCRE2_CONFIG_COMPILED_WIDTHS
+
+       The output is a uint32_t integer whose lower bits indicate  which  code
+       unit  widths  were  selected  when PCRE2 was built. The 1-bit indicates
+       8-bit support, and the 2-bit and 4-bit indicate 16-bit and 32-bit  sup-
+       port, respectively.
+
+         PCRE2_CONFIG_DEPTHLIMIT
+
+       The  output  is a uint32_t integer that gives the default limit for the
+       depth of nested backtracking in pcre2_match() or the  depth  of  nested
+       recursions,  lookarounds,  and atomic groups in pcre2_dfa_match(). Fur-
+       ther details are given with pcre2_set_depth_limit() above.
+
+         PCRE2_CONFIG_HEAPLIMIT
+
+       The output is a uint32_t integer that gives, in kibibytes, the  default
+       limit   for  the  amount  of  heap  memory  used  by  pcre2_match()  or
+       pcre2_dfa_match().     Further     details     are      given      with
+       pcre2_set_heap_limit() above.
+
+         PCRE2_CONFIG_JIT
+
+       The  output  is  a  uint32_t  integer that is set to one if support for
+       just-in-time compiling is included in the library; otherwise it is  set
+       to zero. Note that having the support in the library does not guarantee
+       that  JIT will be used for any given match. See the pcre2jit documenta-
+       tion for more details.
+
+         PCRE2_CONFIG_JITTARGET
+
+       The where argument should point to a buffer that is at  least  48  code
+       units  long.  (The  exact  length  required  can  be  found  by calling
+       pcre2_config() with where set to NULL.) The buffer  is  filled  with  a
+       string  that  contains  the  name of the architecture for which the JIT
+       compiler is configured, for example "x86 32bit  (little  endian  +  un-
+       aligned)".  If  JIT  support is not available, PCRE2_ERROR_BADOPTION is
+       returned, otherwise the number of code units used is returned. This  is
+       the length of the string, plus one unit for the terminating zero.
+
+         PCRE2_CONFIG_LINKSIZE
+
+       The output is a uint32_t integer that contains the number of bytes used
+       for  internal  linkage  in  compiled regular expressions. When PCRE2 is
+       configured, the value can be set to 2, 3, or 4, with the default  being
+       2.  This is the value that is returned by pcre2_config(). However, when
+       the 16-bit library is compiled, a value of 3 is rounded up  to  4,  and
+       when  the  32-bit  library  is compiled, internal linkages always use 4
+       bytes, so the configured value is not relevant.
+
+       The default value of 2 for the 8-bit and 16-bit libraries is sufficient
+       for all but the most massive patterns, since it allows the size of  the
+       compiled  pattern  to  be  up  to 65535 code units. Larger values allow
+       larger regular expressions to be compiled by those two  libraries,  but
+       at the expense of slower matching.
+
+         PCRE2_CONFIG_MATCHLIMIT
+
+       The output is a uint32_t integer that gives the default match limit for
+       pcre2_match().  Further  details are given with pcre2_set_match_limit()
+       above.
+
+         PCRE2_CONFIG_NEWLINE
+
+       The output is a uint32_t integer  whose  value  specifies  the  default
+       character  sequence that is recognized as meaning "newline". The values
+       are:
+
+         PCRE2_NEWLINE_CR       Carriage return (CR)
+         PCRE2_NEWLINE_LF       Linefeed (LF)
+         PCRE2_NEWLINE_CRLF     Carriage return, linefeed (CRLF)
+         PCRE2_NEWLINE_ANY      Any Unicode line ending
+         PCRE2_NEWLINE_ANYCRLF  Any of CR, LF, or CRLF
+         PCRE2_NEWLINE_NUL      The NUL character (binary zero)
+
+       The default should normally correspond to  the  standard  sequence  for
+       your operating system.
+
+         PCRE2_CONFIG_NEVER_BACKSLASH_C
+
+       The  output  is  a uint32_t integer that is set to one if the use of \C
+       was permanently disabled when PCRE2 was built; otherwise it is  set  to
+       zero.
+
+         PCRE2_CONFIG_PARENSLIMIT
+
+       The  output is a uint32_t integer that gives the maximum depth of nest-
+       ing of parentheses (of any kind) in a pattern. This limit is imposed to
+       cap the amount of system stack used when a pattern is compiled.  It  is
+       specified  when PCRE2 is built; the default is 250. This limit does not
+       take into account the stack that may already be used by the calling ap-
+       plication.  For  finer  control  over  compilation  stack  usage,   see
+       pcre2_set_compile_recursion_guard().
+
+         PCRE2_CONFIG_STACKRECURSE
+
+       This parameter is obsolete and should not be used in new code. The out-
+       put is a uint32_t integer that is always set to zero.
+
+         PCRE2_CONFIG_TABLES_LENGTH
+
+       The output is a uint32_t integer that gives the length of PCRE2's char-
+       acter  processing  tables in bytes. For details of these tables see the
+       section on locale support below.
+
+         PCRE2_CONFIG_UNICODE_VERSION
+
+       The where argument should point to a buffer that is at  least  24  code
+       units  long.  (The  exact  length  required  can  be  found  by calling
+       pcre2_config() with where set to NULL.)  If  PCRE2  has  been  compiled
+       without  Unicode  support,  the buffer is filled with the text "Unicode
+       not supported". Otherwise, the Unicode  version  string  (for  example,
+       "8.0.0")  is  inserted. The number of code units used is returned. This
+       is the length of the string plus one unit for the terminating zero.
+
+         PCRE2_CONFIG_UNICODE
+
+       The output is a uint32_t integer that is set to one if Unicode  support
+       is  available; otherwise it is set to zero. Unicode support implies UTF
+       support.
+
+         PCRE2_CONFIG_VERSION
+
+       The where argument should point to a buffer that is at  least  24  code
+       units  long.  (The  exact  length  required  can  be  found  by calling
+       pcre2_config() with where set to NULL.) The buffer is filled  with  the
+       PCRE2 version string, zero-terminated. The number of code units used is
+       returned. This is the length of the string plus one unit for the termi-
+       nating zero.
+
+
+COMPILING A PATTERN
+
+       pcre2_code *pcre2_compile(PCRE2_SPTR pattern, PCRE2_SIZE length,
+         uint32_t options, int *errorcode, PCRE2_SIZE *erroroffset,
+         pcre2_compile_context *ccontext);
+
+       void pcre2_code_free(pcre2_code *code);
+
+       pcre2_code *pcre2_code_copy(const pcre2_code *code);
+
+       pcre2_code *pcre2_code_copy_with_tables(const pcre2_code *code);
+
+       The  pcre2_compile() function compiles a pattern into an internal form.
+       The pattern is defined by a pointer to a string of  code  units  and  a
+       length in code units. If the pattern is zero-terminated, the length can
+       be  specified  as  PCRE2_ZERO_TERMINATED. A NULL pattern pointer with a
+       length of zero is treated as an empty  string  (NULL  with  a  non-zero
+       length  causes  an  error  return). The function returns a pointer to a
+       block of memory that contains the compiled pattern and related data, or
+       NULL if an error occurred.
+
+       If the compile context argument ccontext is NULL, memory for  the  com-
+       piled  pattern  is  obtained  by calling malloc(). Otherwise, it is ob-
+       tained from the same memory function that was used for the compile con-
+       text. The caller must free the memory by calling pcre2_code_free() when
+       it is no longer needed.  If pcre2_code_free() is called with a NULL ar-
+       gument, it returns immediately, without doing anything.
+
+       The function pcre2_code_copy() makes a copy of the compiled code in new
+       memory, using the same memory allocator as was used for  the  original.
+       However,  if  the  code has been processed by the JIT compiler (see be-
+       low), the JIT information cannot be copied (because it is  position-de-
+       pendent).   The  new copy can initially be used only for non-JIT match-
+       ing, though it can be passed to  pcre2_jit_compile()  if  required.  If
+       pcre2_code_copy() is called with a NULL argument, it returns NULL.
+
+       The pcre2_code_copy() function provides a way for individual threads in
+       a  multithreaded  application  to acquire a private copy of shared com-
+       piled code.  However, it does not make a copy of the  character  tables
+       used  by  the compiled pattern; the new pattern code points to the same
+       tables as the original code.  (See "Locale Support" below  for  details
+       of  these  character  tables.) In many applications the same tables are
+       used throughout, so this behaviour is appropriate. Nevertheless,  there
+       are occasions when a copy of a compiled pattern and the relevant tables
+       are  needed.  The pcre2_code_copy_with_tables() provides this facility.
+       Copies of both the code and the tables are  made,  with  the  new  code
+       pointing  to the new tables. The memory for the new tables is automati-
+       cally freed when pcre2_code_free() is called for the new  copy  of  the
+       compiled  code.  If pcre2_code_copy_with_tables() is called with a NULL
+       argument, it returns NULL.
+
+       NOTE: When one of the matching functions is  called,  pointers  to  the
+       compiled pattern and the subject string are set in the match data block
+       so  that  they  can be referenced by the substring extraction functions
+       after a successful match.  After running a match, you must not  free  a
+       compiled  pattern or a subject string until after all operations on the
+       match data block have taken place, unless, in the case of  the  subject
+       string,  you  have used the PCRE2_COPY_MATCHED_SUBJECT option, which is
+       described in the section entitled "Option bits for  pcre2_match()"  be-
+       low.
+
+       The  options argument for pcre2_compile() contains various bit settings
+       that affect the compilation. It should be zero if none of them are  re-
+       quired.  The  available  options  are described below. Some of them (in
+       particular, those that are compatible with Perl,  but  some  others  as
+       well)  can  also  be set and unset from within the pattern (see the de-
+       tailed description in the pcre2pattern documentation).
+
+       For those options that can be different in different parts of the  pat-
+       tern,  the contents of the options argument specifies their settings at
+       the start of compilation. The  PCRE2_ANCHORED,  PCRE2_ENDANCHORED,  and
+       PCRE2_NO_UTF_CHECK  options  can be set at the time of matching as well
+       as at compile time.
+
+       Some additional options and less frequently required compile-time para-
+       meters (for example, the newline setting) can be provided in a  compile
+       context (as described above).
+
+       If errorcode or erroroffset is NULL, pcre2_compile() returns NULL imme-
+       diately.  Otherwise,  the  variables to which these point are set to an
+       error code and an offset (number of code units) within the pattern, re-
+       spectively, when pcre2_compile() returns NULL because a compilation er-
+       ror has occurred.
+
+       There are nearly 100 positive error codes that pcre2_compile() may  re-
+       turn  if it finds an error in the pattern. There are also some negative
+       error codes that are used for invalid UTF strings when validity  check-
+       ing  is  in  force.  These  are  the same as given by pcre2_match() and
+       pcre2_dfa_match(), and are described in the pcre2unicode documentation.
+       There is no separate documentation for the positive  error  codes,  be-
+       cause  the  textual  error  messages  that  are obtained by calling the
+       pcre2_get_error_message() function (see "Obtaining a textual error mes-
+       sage" below) should be  self-explanatory.  Macro  names  starting  with
+       PCRE2_ERROR_  are defined for both positive and negative error codes in
+       pcre2.h. When compilation is successful errorcode is  set  to  a  value
+       that  returns  the message "no error" if passed to pcre2_get_error_mes-
+       sage().
+
+       The value returned in erroroffset is an indication of where in the pat-
+       tern an error occurred. When there is no error,  zero  is  returned.  A
+       non-zero  value  is  not  necessarily the furthest point in the pattern
+       that was read. For example, after the error  "lookbehind  assertion  is
+       not  fixed length", the error offset points to the start of the failing
+       assertion. For an invalid UTF-8 or UTF-16 string, the offset is that of
+       the first code unit of the failing character.
+
+       Some errors are not detected until the whole pattern has been  scanned;
+       in  these  cases,  the offset passed back is the length of the pattern.
+       Note that the offset is in code units, not characters, even  in  a  UTF
+       mode. It may sometimes point into the middle of a UTF-8 or UTF-16 char-
+       acter.
+
+       This  code  fragment shows a typical straightforward call to pcre2_com-
+       pile():
+
+         pcre2_code *re;
+         PCRE2_SIZE erroffset;
+         int errorcode;
+         re = pcre2_compile(
+           "^A.*Z",                /* the pattern */
+           PCRE2_ZERO_TERMINATED,  /* the pattern is zero-terminated */
+           0,                      /* default options */
+           &errorcode,             /* for error code */
+           &erroffset,             /* for error offset */
+           NULL);                  /* no compile context */
+
+
+   Main compile options
+
+       The following names for option bits are defined in the  pcre2.h  header
+       file:
+
+         PCRE2_ANCHORED
+
+       If this bit is set, the pattern is forced to be "anchored", that is, it
+       is  constrained to match only at the first matching point in the string
+       that is being searched (the "subject string"). This effect can also  be
+       achieved  by appropriate constructs in the pattern itself, which is the
+       only way to do it in Perl.
+
+         PCRE2_ALLOW_EMPTY_CLASS
+
+       By default, for compatibility with Perl, a closing square bracket  that
+       immediately  follows  an opening one is treated as a data character for
+       the class. When  PCRE2_ALLOW_EMPTY_CLASS  is  set,  it  terminates  the
+       class, which therefore contains no characters and so can never match.
+
+         PCRE2_ALT_BSUX
+
+       This  option  request  alternative  handling of three escape sequences,
+       which makes PCRE2's behaviour more like  ECMAscript  (aka  JavaScript).
+       When it is set:
+
+       (1) \U matches an upper case "U" character; by default \U causes a com-
+       pile time error (Perl uses \U to upper case subsequent characters).
+
+       (2) \u matches a lower case "u" character unless it is followed by four
+       hexadecimal  digits,  in  which case the hexadecimal number defines the
+       code point to match. By default, \u causes a compile time  error  (Perl
+       uses it to upper case the following character).
+
+       (3)  \x matches a lower case "x" character unless it is followed by two
+       hexadecimal digits, in which case the hexadecimal  number  defines  the
+       code  point  to  match. By default, as in Perl, a hexadecimal number is
+       always expected after \x, but it may have zero, one, or two digits (so,
+       for example, \xz matches a binary zero character followed by z).
+
+       ECMAscript 6 added additional functionality to \u. This can be accessed
+       using the PCRE2_EXTRA_ALT_BSUX extra option  (see  "Extra  compile  op-
+       tions" below).  Note that this alternative escape handling applies only
+       to  patterns.  Neither  of  these options affects the processing of re-
+       placement strings passed to pcre2_substitute().
+
+         PCRE2_ALT_CIRCUMFLEX
+
+       In  multiline  mode  (when  PCRE2_MULTILINE  is  set),  the  circumflex
+       metacharacter  matches at the start of the subject (unless PCRE2_NOTBOL
+       is set), and also after any internal  newline.  However,  it  does  not
+       match after a newline at the end of the subject, for compatibility with
+       Perl.  If  you want a multiline circumflex also to match after a termi-
+       nating newline, you must set PCRE2_ALT_CIRCUMFLEX.
+
+         PCRE2_ALT_VERBNAMES
+
+       By default, for compatibility with Perl, the name in any verb  sequence
+       such  as  (*MARK:NAME)  is any sequence of characters that does not in-
+       clude a closing parenthesis. The name is not processed in any way,  and
+       it  is  not possible to include a closing parenthesis in the name. How-
+       ever, if the PCRE2_ALT_VERBNAMES option is set, normal  backslash  pro-
+       cessing  is  applied to verb names and only an unescaped closing paren-
+       thesis terminates the name. A closing parenthesis can be included in  a
+       name  either  as  \)  or  between  \Q  and \E. If the PCRE2_EXTENDED or
+       PCRE2_EXTENDED_MORE option is set with  PCRE2_ALT_VERBNAMES,  unescaped
+       whitespace  in verb names is skipped and #-comments are recognized, ex-
+       actly as in the rest of the pattern.
+
+         PCRE2_AUTO_CALLOUT
+
+       If this bit  is  set,  pcre2_compile()  automatically  inserts  callout
+       items,  all  with  number 255, before each pattern item, except immedi-
+       ately before or after an explicit callout in the pattern.  For  discus-
+       sion of the callout facility, see the pcre2callout documentation.
+
+         PCRE2_CASELESS
+
+       If  this  bit is set, letters in the pattern match both upper and lower
+       case letters in the subject. It is equivalent to Perl's /i option,  and
+       it  can be changed within a pattern by a (?i) option setting. If either
+       PCRE2_UTF or PCRE2_UCP is set, Unicode  properties  are  used  for  all
+       characters  with more than one other case, and for all characters whose
+       code points are greater than U+007F. Note  that  there  are  two  ASCII
+       characters, K and S, that, in addition to their lower case ASCII equiv-
+       alents,  are case-equivalent with U+212A (Kelvin sign) and U+017F (long
+       S) respectively. If you do not want this case equivalence, you can sup-
+       press it by setting PCRE2_EXTRA_CASELESS_RESTRICT.
+
+       For lower valued characters with only one other case, a lookup table is
+       used for speed. When neither PCRE2_UTF nor PCRE2_UCP is set,  a  lookup
+       table is used for all code points less than 256, and higher code points
+       (available only in 16-bit or 32-bit mode) are treated as not having an-
+       other case.
+
+         PCRE2_DOLLAR_ENDONLY
+
+       If  this bit is set, a dollar metacharacter in the pattern matches only
+       at the end of the subject string. Without this option,  a  dollar  also
+       matches  immediately before a newline at the end of the string (but not
+       before any other newlines). The PCRE2_DOLLAR_ENDONLY option is  ignored
+       if  PCRE2_MULTILINE  is  set.  There is no equivalent to this option in
+       Perl, and no way to set it within a pattern.
+
+         PCRE2_DOTALL
+
+       If this bit is set, a dot metacharacter  in  the  pattern  matches  any
+       character,  including  one  that  indicates a newline. However, it only
+       ever matches one character, even if newlines are coded as CRLF. Without
+       this option, a dot does not match when the current position in the sub-
+       ject is at a newline. This option is equivalent to  Perl's  /s  option,
+       and it can be changed within a pattern by a (?s) option setting. A neg-
+       ative  class such as [^a] always matches newline characters, and the \N
+       escape sequence always matches a non-newline character, independent  of
+       the setting of PCRE2_DOTALL.
+
+         PCRE2_DUPNAMES
+
+       If  this  bit is set, names used to identify capture groups need not be
+       unique.  This can be helpful for certain types of pattern  when  it  is
+       known  that  only  one instance of the named group can ever be matched.
+       There are more details of named capture  groups  below;  see  also  the
+       pcre2pattern documentation.
+
+         PCRE2_ENDANCHORED
+
+       If  this  bit is set, the end of any pattern match must be right at the
+       end of the string being searched (the "subject string"). If the pattern
+       match succeeds by reaching (*ACCEPT), but does not reach the end of the
+       subject, the match fails at the current starting point. For  unanchored
+       patterns,  a  new  match is then tried at the next starting point. How-
+       ever, if the match succeeds by reaching the end of the pattern, but not
+       the end of the subject, backtracking occurs and  an  alternative  match
+       may be found. Consider these two patterns:
+
+         .(*ACCEPT)|..
+         .|..
+
+       If  matched against "abc" with PCRE2_ENDANCHORED set, the first matches
+       "c" whereas the second matches "bc". The  effect  of  PCRE2_ENDANCHORED
+       can  also  be achieved by appropriate constructs in the pattern itself,
+       which is the only way to do it in Perl.
+
+       For DFA matching with pcre2_dfa_match(), PCRE2_ENDANCHORED applies only
+       to the first (that is, the  longest)  matched  string.  Other  parallel
+       matches,  which are necessarily substrings of the first one, must obvi-
+       ously end before the end of the subject.
+
+         PCRE2_EXTENDED
+
+       If this bit is set, most white space characters in the pattern are  to-
+       tally  ignored except when escaped, inside a character class, or inside
+       a \Q...\E sequence. However, white space  is  not  allowed  within  se-
+       quences  such  as  (?> that introduce various parenthesized groups, nor
+       within numerical quantifiers such as {1,3}. Ignorable  white  space  is
+       permitted  between  an  item  and  a following quantifier and between a
+       quantifier and a following + that indicates  possessiveness.  PCRE2_EX-
+       TENDED  is equivalent to Perl's /x option, and it can be changed within
+       a pattern by a (?x) option setting.
+
+       When PCRE2 is compiled without Unicode support,  PCRE2_EXTENDED  recog-
+       nizes  as  white space only those characters with code points less than
+       256 that are flagged as white space in its low-character table. The ta-
+       ble is normally created by pcre2_maketables(), which uses the isspace()
+       function to identify space characters. In most ASCII environments,  the
+       relevant  characters  are  those  with code points 0x0009 (tab), 0x000A
+       (linefeed), 0x000B (vertical tab), 0x000C (formfeed), 0x000D  (carriage
+       return), and 0x0020 (space).
+
+       When PCRE2 is compiled with Unicode support, in addition to these char-
+       acters,  five  more Unicode "Pattern White Space" characters are recog-
+       nized by PCRE2_EXTENDED. These are U+0085 (next line), U+200E (left-to-
+       right mark), U+200F (right-to-left mark), U+2028 (line separator),  and
+       U+2029  (paragraph  separator).  This  set of characters is the same as
+       recognized by Perl's /x option. Note that the horizontal  and  vertical
+       space  characters that are matched by the \h and \v escapes in patterns
+       are a much bigger set.
+
+       As well as ignoring most white space, PCRE2_EXTENDED also causes  char-
+       acters  between  an  unescaped # outside a character class and the next
+       newline, inclusive, to be ignored, which makes it possible  to  include
+       comments inside complicated patterns. Note that the end of this type of
+       comment  is a literal newline sequence in the pattern; escape sequences
+       that happen to represent a newline do not count.
+
+       Which characters are interpreted as newlines can be specified by a set-
+       ting in the compile context that is passed to pcre2_compile() or  by  a
+       special  sequence at the start of the pattern, as described in the sec-
+       tion entitled "Newline conventions" in the pcre2pattern  documentation.
+       A default is defined when PCRE2 is built.
+
+         PCRE2_EXTENDED_MORE
+
+       This  option  has  the  effect of PCRE2_EXTENDED, but, in addition, un-
+       escaped space and horizontal tab characters are ignored inside a  char-
+       acter  class. Note: only these two characters are ignored, not the full
+       set of pattern white space characters that are ignored outside a  char-
+       acter  class.  PCRE2_EXTENDED_MORE  is equivalent to Perl's /xx option,
+       and it can be changed within a pattern by a (?xx) option setting.
+
+         PCRE2_FIRSTLINE
+
+       If this option is set, the start of an unanchored pattern match must be
+       before or at the first newline in  the  subject  string  following  the
+       start  of  matching, though the matched text may continue over the new-
+       line. If startoffset is non-zero, the limiting newline is not necessar-
+       ily the first newline in the  subject.  For  example,  if  the  subject
+       string is "abc\nxyz" (where \n represents a single-character newline) a
+       pattern  match for "yz" succeeds with PCRE2_FIRSTLINE if startoffset is
+       greater than 3. See also PCRE2_USE_OFFSET_LIMIT, which provides a  more
+       general  limiting  facility.  If  PCRE2_FIRSTLINE is set with an offset
+       limit, a match must occur in the first line and also within the  offset
+       limit. In other words, whichever limit comes first is used. This option
+       has no effect for anchored patterns.
+
+         PCRE2_LITERAL
+
+       If this option is set, all meta-characters in the pattern are disabled,
+       and  it is treated as a literal string. Matching literal strings with a
+       regular expression engine is not the most efficient way of doing it. If
+       you are doing a lot of literal matching and  are  worried  about  effi-
+       ciency, you should consider using other approaches. The only other main
+       options  that  are  allowed  with  PCRE2_LITERAL  are:  PCRE2_ANCHORED,
+       PCRE2_ENDANCHORED, PCRE2_AUTO_CALLOUT, PCRE2_CASELESS, PCRE2_FIRSTLINE,
+       PCRE2_MATCH_INVALID_UTF,  PCRE2_NO_START_OPTIMIZE,  PCRE2_NO_UTF_CHECK,
+       PCRE2_UTF,  and  PCRE2_USE_OFFSET_LIMIT.  The  extra  options PCRE2_EX-
+       TRA_MATCH_LINE and PCRE2_EXTRA_MATCH_WORD are also supported. Any other
+       options cause an error.
+
+         PCRE2_MATCH_INVALID_UTF
+
+       This option forces PCRE2_UTF (see below) and also enables  support  for
+       matching  by  pcre2_match() in subject strings that contain invalid UTF
+       sequences.  Note, however, that the 16-bit and 32-bit  PCRE2  libraries
+       process  strings as sequences of uint16_t or uint32_t code points. They
+       cannot find valid UTF sequences within an arbitrary string of bytes un-
+       less such sequences are suitably aligned. This  facility  is  not  sup-
+       ported  for  DFA matching. For details, see the pcre2unicode documenta-
+       tion.
+
+         PCRE2_MATCH_UNSET_BACKREF
+
+       If this option is set,  a  backreference  to  an  unset  capture  group
+       matches  an  empty  string (by default this causes the current matching
+       alternative to fail).  A pattern such as (\1)(a) succeeds when this op-
+       tion is set (assuming it can find an "a" in the  subject),  whereas  it
+       fails  by  default,  for  Perl compatibility. Setting this option makes
+       PCRE2 behave more like ECMAscript (aka JavaScript).
+
+         PCRE2_MULTILINE
+
+       By default, for the purposes of matching "start of line"  and  "end  of
+       line",  PCRE2  treats the subject string as consisting of a single line
+       of characters, even if it actually contains  newlines.  The  "start  of
+       line"  metacharacter  (^)  matches only at the start of the string, and
+       the "end of line" metacharacter ($) matches only  at  the  end  of  the
+       string,  or  before a terminating newline (except when PCRE2_DOLLAR_EN-
+       DONLY is set). Note, however, that unless PCRE2_DOTALL is set, the "any
+       character" metacharacter (.) does not match at a newline.  This  behav-
+       iour (for ^, $, and dot) is the same as Perl.
+
+       When  PCRE2_MULTILINE  it is set, the "start of line" and "end of line"
+       constructs match immediately following or immediately  before  internal
+       newlines  in  the  subject string, respectively, as well as at the very
+       start and end. This is equivalent to Perl's /m option, and  it  can  be
+       changed within a pattern by a (?m) option setting. Note that the "start
+       of line" metacharacter does not match after a newline at the end of the
+       subject,  for compatibility with Perl.  However, you can change this by
+       setting the PCRE2_ALT_CIRCUMFLEX option. If there are no newlines in  a
+       subject  string,  or  no  occurrences  of  ^ or $ in a pattern, setting
+       PCRE2_MULTILINE has no effect.
+
+         PCRE2_NEVER_BACKSLASH_C
+
+       This option locks out the use of \C in the pattern that is  being  com-
+       piled.   This  escape  can  cause  unpredictable  behaviour in UTF-8 or
+       UTF-16 modes, because it may leave the current matching  point  in  the
+       middle of a multi-code-unit character. This option may be useful in ap-
+       plications that process patterns from external sources. Note that there
+       is also a build-time option that permanently locks out the use of \C.
+
+         PCRE2_NEVER_UCP
+
+       This  option  locks  out the use of Unicode properties for handling \B,
+       \b, \D, \d, \S, \s, \W, \w, and some of the POSIX character classes, as
+       described for the PCRE2_UCP option below. In  particular,  it  prevents
+       the  creator of the pattern from enabling this facility by starting the
+       pattern with (*UCP). This option may be  useful  in  applications  that
+       process patterns from external sources. The option combination PCRE_UCP
+       and PCRE_NEVER_UCP causes an error.
+
+         PCRE2_NEVER_UTF
+
+       This  option  locks out interpretation of the pattern as UTF-8, UTF-16,
+       or UTF-32, depending on which library is in use. In particular, it pre-
+       vents the creator of the pattern from switching to  UTF  interpretation
+       by  starting  the pattern with (*UTF). This option may be useful in ap-
+       plications that process patterns from external sources. The combination
+       of PCRE2_UTF and PCRE2_NEVER_UTF causes an error.
+
+         PCRE2_NO_AUTO_CAPTURE
+
+       If this option is set, it disables the use of numbered capturing paren-
+       theses in the pattern. Any opening parenthesis that is not followed  by
+       ?  behaves as if it were followed by ?: but named parentheses can still
+       be used for capturing (and they acquire numbers in the usual way). This
+       is the same as Perl's /n option.  Note that, when this option  is  set,
+       references  to  capture  groups (backreferences or recursion/subroutine
+       calls) may only refer to named groups, though the reference can  be  by
+       name or by number.
+
+         PCRE2_NO_AUTO_POSSESS
+
+       If this option is set, it disables "auto-possessification", which is an
+       optimization  that,  for example, turns a+b into a++b in order to avoid
+       backtracks into a+ that can never be successful. However,  if  callouts
+       are  in  use,  auto-possessification means that some callouts are never
+       taken. You can set this option if you want the matching functions to do
+       a full unoptimized search and run all the callouts, but  it  is  mainly
+       provided for testing purposes.
+
+         PCRE2_NO_DOTSTAR_ANCHOR
+
+       If this option is set, it disables an optimization that is applied when
+       .*  is  the  first significant item in a top-level branch of a pattern,
+       and all the other branches also start with .* or with \A or  \G  or  ^.
+       The  optimization  is  automatically disabled for .* if it is inside an
+       atomic group or a capture group that is the subject of a backreference,
+       or if the pattern contains (*PRUNE) or (*SKIP). When  the  optimization
+       is   not   disabled,  such  a  pattern  is  automatically  anchored  if
+       PCRE2_DOTALL is set for all the .* items and PCRE2_MULTILINE is not set
+       for any ^ items. Otherwise, the fact that any match must  start  either
+       at  the start of the subject or following a newline is remembered. Like
+       other optimizations, this can cause callouts to be skipped.
+
+         PCRE2_NO_START_OPTIMIZE
+
+       This is an option whose main effect is at matching time.  It  does  not
+       change what pcre2_compile() generates, but it does affect the output of
+       the JIT compiler.
+
+       There  are  a  number of optimizations that may occur at the start of a
+       match, in order to speed up the process. For example, if  it  is  known
+       that  an  unanchored  match must start with a specific code unit value,
+       the matching code searches the subject for that value, and fails  imme-
+       diately  if it cannot find it, without actually running the main match-
+       ing function. This means that a special item such as (*COMMIT)  at  the
+       start  of  a  pattern is not considered until after a suitable starting
+       point for the match has been found.  Also,  when  callouts  or  (*MARK)
+       items  are  in use, these "start-up" optimizations can cause them to be
+       skipped if the pattern is never actually used. The  start-up  optimiza-
+       tions  are  in effect a pre-scan of the subject that takes place before
+       the pattern is run.
+
+       The PCRE2_NO_START_OPTIMIZE option disables the start-up optimizations,
+       possibly causing performance to suffer,  but  ensuring  that  in  cases
+       where  the  result is "no match", the callouts do occur, and that items
+       such as (*COMMIT) and (*MARK) are considered at every possible starting
+       position in the subject string.
+
+       Setting PCRE2_NO_START_OPTIMIZE may change the outcome  of  a  matching
+       operation.  Consider the pattern
+
+         (*COMMIT)ABC
+
+       When  this  is compiled, PCRE2 records the fact that a match must start
+       with the character "A". Suppose the subject  string  is  "DEFABC".  The
+       start-up  optimization  scans along the subject, finds "A" and runs the
+       first match attempt from there. The (*COMMIT) item means that the  pat-
+       tern  must  match the current starting position, which in this case, it
+       does. However, if the same match is  run  with  PCRE2_NO_START_OPTIMIZE
+       set,  the  initial  scan  along the subject string does not happen. The
+       first match attempt is run starting  from  "D"  and  when  this  fails,
+       (*COMMIT)  prevents any further matches being tried, so the overall re-
+       sult is "no match".
+
+       As another start-up optimization makes use of a minimum  length  for  a
+       matching subject, which is recorded when possible. Consider the pattern
+
+         (*MARK:1)B(*MARK:2)(X|Y)
+
+       The  minimum  length  for  a match is two characters. If the subject is
+       "XXBB", the "starting character" optimization skips "XX", then tries to
+       match "BB", which is long enough. In the process, (*MARK:2) is  encoun-
+       tered  and  remembered.  When  the match attempt fails, the next "B" is
+       found, but there is only one character left, so there are no  more  at-
+       tempts,  and  "no  match"  is returned with the "last mark seen" set to
+       "2". If NO_START_OPTIMIZE is set, however, matches are tried  at  every
+       possible  starting position, including at the end of the subject, where
+       (*MARK:1) is encountered, but there is no "B", so the "last mark  seen"
+       that  is returned is "1". In this case, the optimizations do not affect
+       the overall match result, which is still "no match", but they do affect
+       the auxiliary information that is returned.
+
+         PCRE2_NO_UTF_CHECK
+
+       When PCRE2_UTF is set, the validity of the pattern as a UTF  string  is
+       automatically  checked.  There  are  discussions  about the validity of
+       UTF-8 strings, UTF-16 strings, and UTF-32 strings in  the  pcre2unicode
+       document.  If an invalid UTF sequence is found, pcre2_compile() returns
+       a negative error code.
+
+       If you know that your pattern is a valid UTF string, and  you  want  to
+       skip   this   check   for   performance   reasons,   you  can  set  the
+       PCRE2_NO_UTF_CHECK option. When it is set, the effect of passing an in-
+       valid UTF string as a pattern is undefined. It may cause  your  program
+       to crash or loop.
+
+       Note  that  this  option  can  also  be  passed  to  pcre2_match()  and
+       pcre2_dfa_match(), to suppress UTF validity  checking  of  the  subject
+       string.
+
+       Note also that setting PCRE2_NO_UTF_CHECK at compile time does not dis-
+       able  the error that is given if an escape sequence for an invalid Uni-
+       code code point is encountered in the pattern. In particular,  the  so-
+       called  "surrogate"  code points (0xd800 to 0xdfff) are invalid. If you
+       want to allow escape  sequences  such  as  \x{d800}  you  can  set  the
+       PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES  extra  option, as described in the
+       section entitled "Extra compile options" below.  However, this is  pos-
+       sible only in UTF-8 and UTF-32 modes, because these values are not rep-
+       resentable in UTF-16.
+
+         PCRE2_UCP
+
+       This option has two effects. Firstly, it change the way PCRE2 processes
+       \B,  \b,  \D,  \d,  \S,  \s,  \W,  \w,  and some of the POSIX character
+       classes. By default, only  ASCII  characters  are  recognized,  but  if
+       PCRE2_UCP  is  set, Unicode properties are used to classify characters.
+       There are some PCRE2_EXTRA options (see below) that add  finer  control
+       to  this  behaviour.  More  details are given in the section on generic
+       character types in the pcre2pattern page.
+
+       The second effect of PCRE2_UCP is to force the use of  Unicode  proper-
+       ties for upper/lower casing operations, even when PCRE2_UTF is not set.
+       This  makes  it  possible  to process strings in the 16-bit UCS-2 code.
+       This option is available only if PCRE2 has been compiled  with  Unicode
+       support  (which is the default).  The PCRE2_EXTRA_CASELESS_RESTRICT op-
+       tion (see below) restricts caseless matching such that ASCII characters
+       match only ASCII characters and non-ASCII characters  match  only  non-
+       ASCII characters.
+
+         PCRE2_UNGREEDY
+
+       This  option  inverts  the "greediness" of the quantifiers so that they
+       are not greedy by default, but become greedy if followed by "?". It  is
+       not  compatible  with Perl. It can also be set by a (?U) option setting
+       within the pattern.
+
+         PCRE2_USE_OFFSET_LIMIT
+
+       This option must be set for pcre2_compile() if pcre2_set_offset_limit()
+       is going to be used to set a non-default offset limit in a  match  con-
+       text  for  matches  that  use this pattern. An error is generated if an
+       offset limit is set without this option. For more details, see the  de-
+       scription  of  pcre2_set_offset_limit()  in  the section that describes
+       match contexts. See also the PCRE2_FIRSTLINE option above.
+
+         PCRE2_UTF
+
+       This option causes PCRE2 to regard both the  pattern  and  the  subject
+       strings  that  are  subsequently processed as strings of UTF characters
+       instead of single-code-unit strings. It  is  available  when  PCRE2  is
+       built  to  include  Unicode  support (which is the default). If Unicode
+       support is not available, the use of this option provokes an error. De-
+       tails of how PCRE2_UTF changes the behaviour of PCRE2 are given in  the
+       pcre2unicode  page.  In  particular,  note  that  it  changes  the  way
+       PCRE2_CASELESS works.
+
+   Extra compile options
+
+       The option bits that can be set in a compile  context  by  calling  the
+       pcre2_set_compile_extra_options() function are as follows:
+
+         PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK
+
+       Since release 10.38 PCRE2 has forbidden the use of \K within lookaround
+       assertions, following Perl's lead. This option is provided to re-enable
+       the previous behaviour (act in positive lookarounds, ignore in negative
+       ones) in case anybody is relying on it.
+
+         PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES
+
+       This  option  applies when compiling a pattern in UTF-8 or UTF-32 mode.
+       It is forbidden in UTF-16 mode, and ignored in non-UTF  modes.  Unicode
+       "surrogate" code points in the range 0xd800 to 0xdfff are used in pairs
+       in  UTF-16  to  encode  code points with values in the range 0x10000 to
+       0x10ffff. The surrogates cannot therefore  be  represented  in  UTF-16.
+       They can be represented in UTF-8 and UTF-32, but are defined as invalid
+       code  points,  and  cause  errors  if  encountered in a UTF-8 or UTF-32
+       string that is being checked for validity by PCRE2.
+
+       These values also cause errors if encountered in escape sequences  such
+       as \x{d912} within a pattern. However, it seems that some applications,
+       when using PCRE2 to check for unwanted characters in UTF-8 strings, ex-
+       plicitly   test   for   the  surrogates  using  escape  sequences.  The
+       PCRE2_NO_UTF_CHECK option does not disable the error that  occurs,  be-
+       cause it applies only to the testing of input strings for UTF validity.
+
+       If  the extra option PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES is set, surro-
+       gate code point values in UTF-8 and UTF-32 patterns no  longer  provoke
+       errors  and are incorporated in the compiled pattern. However, they can
+       only match subject characters if the matching function is  called  with
+       PCRE2_NO_UTF_CHECK set.
+
+         PCRE2_EXTRA_ALT_BSUX
+
+       The  original option PCRE2_ALT_BSUX causes PCRE2 to process \U, \u, and
+       \x in the way that ECMAscript (aka JavaScript) does.  Additional  func-
+       tionality was defined by ECMAscript 6; setting PCRE2_EXTRA_ALT_BSUX has
+       the  effect  of PCRE2_ALT_BSUX, but in addition it recognizes \u{hhh..}
+       as a hexadecimal character code, where hhh.. is any number of hexadeci-
+       mal digits.
+
+         PCRE2_EXTRA_ASCII_BSD
+
+       This option forces \d to match only ASCII digits, even  when  PCRE2_UCP
+       is  set.   It can be changed within a pattern by means of the (?aD) op-
+       tion setting.
+
+         PCRE2_EXTRA_ASCII_BSS
+
+       This option forces \s to match only ASCII space characters,  even  when
+       PCRE2_UCP  is  set.  It can be changed within a pattern by means of the
+       (?aS) option setting.
+
+         PCRE2_EXTRA_ASCII_BSW
+
+       This option forces \w to match only ASCII word  characters,  even  when
+       PCRE2_UCP  is  set.  It can be changed within a pattern by means of the
+       (?aW) option setting.
+
+         PCRE2_EXTRA_ASCII_DIGIT
+
+       This option forces the POSIX character classes [:digit:] and [:xdigit:]
+       to match only ASCII digits, even when  PCRE2_UCP  is  set.  It  can  be
+       changed within a pattern by means of the (?aT) option setting.
+
+         PCRE2_EXTRA_ASCII_POSIX
+
+       This option forces all the POSIX character classes, including [:digit:]
+       and  [:xdigit:], to match only ASCII characters, even when PCRE2_UCP is
+       set. It can be changed within a pattern by means of  the  (?aP)  option
+       setting,  but note that this also sets PCRE2_EXTRA_ASCII_DIGIT in order
+       to ensure that (?-aP) unsets all ASCII restrictions for POSIX classes.
+
+         PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL
+
+       This is a dangerous option. Use with care. By default, an  unrecognized
+       escape  such  as \j or a malformed one such as \x{2z} causes a compile-
+       time error when detected by pcre2_compile(). Perl is somewhat inconsis-
+       tent in handling such items: for example, \j is treated  as  a  literal
+       "j",  and non-hexadecimal digits in \x{} are just ignored, though warn-
+       ings are given in both cases if Perl's warning switch is enabled.  How-
+       ever,  a  malformed  octal  number  after \o{ always causes an error in
+       Perl.
+
+       If the PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL  extra  option  is  passed  to
+       pcre2_compile(),  all  unrecognized  or  malformed escape sequences are
+       treated as single-character escapes. For example, \j is a  literal  "j"
+       and  \x{2z}  is treated as the literal string "x{2z}". Setting this op-
+       tion means that typos in patterns may go undetected and have unexpected
+       results. Also note that a sequence such as [\N{] is  interpreted  as  a
+       malformed  attempt  at [\N{...}] and so is treated as [N{] whereas [\N]
+       gives an error because an unqualified \N is a valid escape sequence but
+       is not supported in a character class. To reiterate: this is a  danger-
+       ous option. Use with great care.
+
+         PCRE2_EXTRA_CASELESS_RESTRICT
+
+       When  either  PCRE2_UCP  or PCRE2_UTF is set, caseless matching follows
+       Unicode rules, which allow for more than two cases per character. There
+       are two case-equivalent character sets that contain both ASCII and non-
+       ASCII characters. The ASCII letter S is case-equivalent to U+017f (long
+       S) and the ASCII letter K is case-equivalent to U+212a  (Kelvin  sign).
+       This  option  disables  recognition of case-equivalences that cross the
+       ASCII/non-ASCII boundary. In a caseless match, both characters must ei-
+       ther be ASCII or non-ASCII. The option can be changed with a pattern by
+       the (?r) option setting.
+
+         PCRE2_EXTRA_ESCAPED_CR_IS_LF
+
+       There are some legacy applications where the escape sequence  \r  in  a
+       pattern  is expected to match a newline. If this option is set, \r in a
+       pattern is converted to \n so that it matches a LF  (linefeed)  instead
+       of  a CR (carriage return) character. The option does not affect a lit-
+       eral CR in the pattern, nor does it affect CR specified as an  explicit
+       code point such as \x{0D}.
+
+         PCRE2_EXTRA_MATCH_LINE
+
+       This  option  is  provided  for  use  by the -x option of pcre2grep. It
+       causes the pattern only to match complete lines. This  is  achieved  by
+       automatically  inserting  the  code for "^(?:" at the start of the com-
+       piled pattern and ")$" at the end. Thus, when PCRE2_MULTILINE  is  set,
+       the  matched  line may be in the middle of the subject string. This op-
+       tion can be used with PCRE2_LITERAL.
+
+         PCRE2_EXTRA_MATCH_WORD
+
+       This option is provided for use by  the  -w  option  of  pcre2grep.  It
+       causes  the  pattern only to match strings that have a word boundary at
+       the start and the end. This is achieved by automatically inserting  the
+       code  for "\b(?:" at the start of the compiled pattern and ")\b" at the
+       end. The option may be used with PCRE2_LITERAL. However, it is  ignored
+       if PCRE2_EXTRA_MATCH_LINE is also set.
+
+
+JUST-IN-TIME (JIT) COMPILATION
+
+       int pcre2_jit_compile(pcre2_code *code, uint32_t options);
+
+       int pcre2_jit_match(const pcre2_code *code, PCRE2_SPTR subject,
+         PCRE2_SIZE length, PCRE2_SIZE startoffset,
+         uint32_t options, pcre2_match_data *match_data,
+         pcre2_match_context *mcontext);
+
+       void pcre2_jit_free_unused_memory(pcre2_general_context *gcontext);
+
+       pcre2_jit_stack *pcre2_jit_stack_create(size_t startsize,
+         size_t maxsize, pcre2_general_context *gcontext);
+
+       void pcre2_jit_stack_assign(pcre2_match_context *mcontext,
+         pcre2_jit_callback callback_function, void *callback_data);
+
+       void pcre2_jit_stack_free(pcre2_jit_stack *jit_stack);
+
+       These  functions  provide  support  for  JIT compilation, which, if the
+       just-in-time compiler is available, further processes a  compiled  pat-
+       tern into machine code that executes much faster than the pcre2_match()
+       interpretive  matching function. Full details are given in the pcre2jit
+       documentation.
+
+       JIT compilation is a heavyweight optimization. It can  take  some  time
+       for  patterns  to  be analyzed, and for one-off matches and simple pat-
+       terns the benefit of faster execution might be offset by a much  slower
+       compilation  time.  Most (but not all) patterns can be optimized by the
+       JIT compiler.
+
+
+LOCALE SUPPORT
+
+       const uint8_t *pcre2_maketables(pcre2_general_context *gcontext);
+
+       void pcre2_maketables_free(pcre2_general_context *gcontext,
+         const uint8_t *tables);
+
+       PCRE2 handles caseless matching, and determines whether characters  are
+       letters,  digits, or whatever, by reference to a set of tables, indexed
+       by character code point. However, this applies only to characters whose
+       code points are less than 256. By default,  higher-valued  code  points
+       never match escapes such as \w or \d.
+
+       When PCRE2 is built with Unicode support (the default), certain Unicode
+       character  properties  can be tested with \p and \P, or, alternatively,
+       the PCRE2_UCP option can be set when a pattern is compiled; this causes
+       \w and friends to use Unicode property support instead of the  built-in
+       tables.  PCRE2_UCP also causes upper/lower casing operations on charac-
+       ters with code points greater than 127 to use Unicode properties. These
+       effects  apply even when PCRE2_UTF is not set. There are, however, some
+       PCRE2_EXTRA options (see above) that can be used to modify or  suppress
+       them.
+
+       The  use  of  locales  with Unicode is discouraged. If you are handling
+       characters with code points greater than 127,  you  should  either  use
+       Unicode support, or use locales, but not try to mix the two.
+
+       PCRE2  contains a built-in set of character tables that are used by de-
+       fault.  These are sufficient for many applications. Normally,  the  in-
+       ternal  tables  recognize only ASCII characters. However, when PCRE2 is
+       built, it is possible to cause the internal tables to be rebuilt in the
+       default "C" locale of the local system, which may cause them to be dif-
+       ferent.
+
+       The built-in tables can be overridden by tables supplied by the  appli-
+       cation  that  calls  PCRE2.  These may be created in a different locale
+       from the default.  As more and more applications change to  using  Uni-
+       code, the need for this locale support is expected to die away.
+
+       External  tables  are built by calling the pcre2_maketables() function,
+       in the relevant locale. The only argument to this function is a general
+       context, which can be used to pass a custom memory  allocator.  If  the
+       argument is NULL, the system malloc() is used. The result can be passed
+       to pcre2_compile() as often as necessary, by creating a compile context
+       and  calling  pcre2_set_character_tables()  to  set  the tables pointer
+       therein.
+
+       For example, to build and use  tables  that  are  appropriate  for  the
+       French  locale  (where accented characters with values greater than 127
+       are treated as letters), the following code could be used:
+
+         setlocale(LC_CTYPE, "fr_FR");
+         tables = pcre2_maketables(NULL);
+         ccontext = pcre2_compile_context_create(NULL);
+         pcre2_set_character_tables(ccontext, tables);
+         re = pcre2_compile(..., ccontext);
+
+       The locale name "fr_FR" is used on Linux and other  Unix-like  systems;
+       if you are using Windows, the name for the French locale is "french".
+
+       The pointer that is passed (via the compile context) to pcre2_compile()
+       is saved with the compiled pattern, and the same tables are used by the
+       matching  functions.  Thus,  for  any  single  pattern, compilation and
+       matching both happen in the same locale, but different patterns can  be
+       processed in different locales.
+
+       It  is the caller's responsibility to ensure that the memory containing
+       the tables remains available while they are still in use. When they are
+       no longer needed, you can discard them  using  pcre2_maketables_free(),
+       which  should  pass as its first parameter the same global context that
+       was used to create the tables.
+
+   Saving locale tables
+
+       The tables described above are just a sequence of binary  bytes,  which
+       makes  them  independent of hardware characteristics such as endianness
+       or whether the processor is 32-bit or 64-bit. A copy of the  result  of
+       pcre2_maketables()  can  therefore  be saved in a file or elsewhere and
+       re-used later, even in a different program or on another computer.  The
+       size  of  the  tables  (number  of  bytes)  must be obtained by calling
+       pcre2_config()  with  the  PCRE2_CONFIG_TABLES_LENGTH  option   because
+       pcre2_maketables()   does   not   return  this  value.  Note  that  the
+       pcre2_dftables program, which is part of the PCRE2 build system, can be
+       used stand-alone to create a file that contains a set of binary tables.
+       See the pcre2build documentation for details.
+
+
+INFORMATION ABOUT A COMPILED PATTERN
+
+       int pcre2_pattern_info(const pcre2 *code, uint32_t what, void *where);
+
+       The pcre2_pattern_info() function returns general information  about  a
+       compiled pattern. For information about callouts, see the next section.
+       The  first  argument  for pcre2_pattern_info() is a pointer to the com-
+       piled pattern. The second argument specifies which piece of information
+       is required, and the third argument is a pointer to a variable  to  re-
+       ceive  the  data.  If the third argument is NULL, the first argument is
+       ignored, and the function returns the size in  bytes  of  the  variable
+       that is required for the information requested. Otherwise, the yield of
+       the function is zero for success, or one of the following negative num-
+       bers:
+
+         PCRE2_ERROR_NULL           the argument code was NULL
+         PCRE2_ERROR_BADMAGIC       the "magic number" was not found
+         PCRE2_ERROR_BADOPTION      the value of what was invalid
+         PCRE2_ERROR_UNSET          the requested field is not set
+
+       The "magic number" is placed at the start of each compiled pattern as a
+       simple  check  against  passing  an arbitrary memory pointer. Here is a
+       typical call of pcre2_pattern_info(), to obtain the length of the  com-
+       piled pattern:
+
+         int rc;
+         size_t length;
+         rc = pcre2_pattern_info(
+           re,               /* result of pcre2_compile() */
+           PCRE2_INFO_SIZE,  /* what is required */
+           &length);         /* where to put the data */
+
+       The possible values for the second argument are defined in pcre2.h, and
+       are as follows:
+
+         PCRE2_INFO_ALLOPTIONS
+         PCRE2_INFO_ARGOPTIONS
+         PCRE2_INFO_EXTRAOPTIONS
+
+       Return copies of the pattern's options. The third argument should point
+       to  a  uint32_t variable. PCRE2_INFO_ARGOPTIONS returns exactly the op-
+       tions that were passed to  pcre2_compile(),  whereas  PCRE2_INFO_ALLOP-
+       TIONS  returns  the compile options as modified by any top-level (*XXX)
+       option settings such as (*UTF) at the  start  of  the  pattern  itself.
+       PCRE2_INFO_EXTRAOPTIONS  returns the extra options that were set in the
+       compile context by calling the pcre2_set_compile_extra_options()  func-
+       tion.
+
+       For  example, if the pattern /(*UTF)abc/ is compiled with the PCRE2_EX-
+       TENDED option, the result for PCRE2_INFO_ALLOPTIONS  is  PCRE2_EXTENDED
+       and  PCRE2_UTF.   Option settings such as (?i) that can change within a
+       pattern do not affect the result of PCRE2_INFO_ALLOPTIONS, even if they
+       appear right at the start of the pattern. (This was different  in  some
+       earlier releases.)
+
+       A  pattern compiled without PCRE2_ANCHORED is automatically anchored by
+       PCRE2 if the first significant item in every top-level branch is one of
+       the following:
+
+         ^     unless PCRE2_MULTILINE is set
+         \A    always
+         \G    always
+         .*    sometimes - see below
+
+       When .* is the first significant item, anchoring is possible only  when
+       all the following are true:
+
+         .* is not in an atomic group
+         .* is not in a capture group that is the subject
+              of a backreference
+         PCRE2_DOTALL is in force for .*
+         Neither (*PRUNE) nor (*SKIP) appears in the pattern
+         PCRE2_NO_DOTSTAR_ANCHOR is not set
+
+       For  patterns  that are auto-anchored, the PCRE2_ANCHORED bit is set in
+       the options returned for PCRE2_INFO_ALLOPTIONS.
+
+         PCRE2_INFO_BACKREFMAX
+
+       Return the number of the highest  backreference  in  the  pattern.  The
+       third  argument  should  point  to  a  uint32_t variable. Named capture
+       groups acquire numbers as well as names, and these  count  towards  the
+       highest  backreference.  Backreferences  such as \4 or \g{12} match the
+       captured characters of the given group, but in addition, the check that
+       a capture group is set in a conditional group such as (?(3)a|b) is also
+       a backreference.  Zero is returned if there are no backreferences.
+
+         PCRE2_INFO_BSR
+
+       The output is a uint32_t integer whose value indicates  what  character
+       sequences  the \R escape sequence matches. A value of PCRE2_BSR_UNICODE
+       means that \R matches any Unicode line  ending  sequence;  a  value  of
+       PCRE2_BSR_ANYCRLF means that \R matches only CR, LF, or CRLF.
+
+         PCRE2_INFO_CAPTURECOUNT
+
+       Return  the  highest  capture  group number in the pattern. In patterns
+       where (?| is not used, this is also the total number of capture groups.
+       The third argument should point to a uint32_t variable.
+
+         PCRE2_INFO_DEPTHLIMIT
+
+       If the pattern set a backtracking depth limit by including an  item  of
+       the  form  (*LIMIT_DEPTH=nnnn) at the start, the value is returned. The
+       third argument should point to a uint32_t integer. If no such value has
+       been set, the call to pcre2_pattern_info() returns the error  PCRE2_ER-
+       ROR_UNSET. Note that this limit will only be used during matching if it
+       is  less  than  the  limit  set or defaulted by the caller of the match
+       function.
+
+         PCRE2_INFO_FIRSTBITMAP
+
+       In the absence of a single first code unit for a non-anchored  pattern,
+       pcre2_compile()  may construct a 256-bit table that defines a fixed set
+       of values for the first code unit in any match. For example, a  pattern
+       that  starts  with  [abc]  results in a table with three bits set. When
+       code unit values greater than 255 are supported, the flag bit  for  255
+       means  "any  code unit of value 255 or above". If such a table was con-
+       structed, a pointer to it is returned. Otherwise NULL is returned.  The
+       third argument should point to a const uint8_t * variable.
+
+         PCRE2_INFO_FIRSTCODETYPE
+
+       Return information about the first code unit of any matched string, for
+       a  non-anchored  pattern. The third argument should point to a uint32_t
+       variable. If there is a fixed first value, for example, the letter  "c"
+       from  a  pattern such as (cat|cow|coyote), 1 is returned, and the value
+       can be retrieved using PCRE2_INFO_FIRSTCODEUNIT. If there is  no  fixed
+       first  value,  but it is known that a match can occur only at the start
+       of the subject or following a newline in the subject,  2  is  returned.
+       Otherwise, and for anchored patterns, 0 is returned.
+
+         PCRE2_INFO_FIRSTCODEUNIT
+
+       Return  the  value  of  the first code unit of any matched string for a
+       pattern where PCRE2_INFO_FIRSTCODETYPE returns 1; otherwise  return  0.
+       The  third  argument  should point to a uint32_t variable. In the 8-bit
+       library, the value is always less than 256. In the 16-bit  library  the
+       value  can  be  up  to 0xffff. In the 32-bit library in UTF-32 mode the
+       value can be up to 0x10ffff, and up to 0xffffffff when not using UTF-32
+       mode.
+
+         PCRE2_INFO_FRAMESIZE
+
+       Return the size (in bytes) of the data frames that are used to remember
+       backtracking positions when the pattern is processed  by  pcre2_match()
+       without  the  use  of  JIT. The third argument should point to a size_t
+       variable. The frame size depends on the number of capturing parentheses
+       in the pattern. Each additional capture group adds two PCRE2_SIZE vari-
+       ables.
+
+         PCRE2_INFO_HASBACKSLASHC
+
+       Return 1 if the pattern contains any instances of \C, otherwise 0.  The
+       third argument should point to a uint32_t variable.
+
+         PCRE2_INFO_HASCRORLF
+
+       Return  1  if  the  pattern  contains any explicit matches for CR or LF
+       characters, otherwise 0. The third argument should point to a  uint32_t
+       variable.  An explicit match is either a literal CR or LF character, or
+       \r or \n or one of the  equivalent  hexadecimal  or  octal  escape  se-
+       quences.
+
+         PCRE2_INFO_HEAPLIMIT
+
+       If the pattern set a heap memory limit by including an item of the form
+       (*LIMIT_HEAP=nnnn) at the start, the value is returned. The third argu-
+       ment should point to a uint32_t integer. If no such value has been set,
+       the  call  to pcre2_pattern_info() returns the error PCRE2_ERROR_UNSET.
+       Note that this limit will only be used during matching if  it  is  less
+       than the limit set or defaulted by the caller of the match function.
+
+         PCRE2_INFO_JCHANGED
+
+       Return  1  if  the (?J) or (?-J) option setting is used in the pattern,
+       otherwise 0. The third argument should point to  a  uint32_t  variable.
+       (?J)  and  (?-J) set and unset the local PCRE2_DUPNAMES option, respec-
+       tively.
+
+         PCRE2_INFO_JITSIZE
+
+       If the compiled pattern was successfully  processed  by  pcre2_jit_com-
+       pile(),  return  the  size  of  the JIT compiled code, otherwise return
+       zero. The third argument should point to a size_t variable.
+
+         PCRE2_INFO_LASTCODETYPE
+
+       Returns 1 if there is a rightmost literal code unit that must exist  in
+       any  matched string, other than at its start. The third argument should
+       point to a uint32_t variable. If there is no such value, 0 is returned.
+       When 1 is returned, the code unit value itself can be  retrieved  using
+       PCRE2_INFO_LASTCODEUNIT. For anchored patterns, a last literal value is
+       recorded  only if it follows something of variable length. For example,
+       for the pattern /^a\d+z\d+/ the returned value is 1 (with "z"  returned
+       from  PCRE2_INFO_LASTCODEUNIT), but for /^a\dz\d/ the returned value is
+       0.
+
+         PCRE2_INFO_LASTCODEUNIT
+
+       Return the value of the rightmost literal code unit that must exist  in
+       any  matched  string,  other  than  at  its  start, for a pattern where
+       PCRE2_INFO_LASTCODETYPE returns 1. Otherwise, return 0. The third argu-
+       ment should point to a uint32_t variable.
+
+         PCRE2_INFO_MATCHEMPTY
+
+       Return 1 if the pattern might match an empty string, otherwise  0.  The
+       third argument should point to a uint32_t variable. When a pattern con-
+       tains recursive subroutine calls it is not always possible to determine
+       whether or not it can match an empty string. PCRE2 takes a cautious ap-
+       proach and returns 1 in such cases.
+
+         PCRE2_INFO_MATCHLIMIT
+
+       If  the  pattern  set  a  match  limit by including an item of the form
+       (*LIMIT_MATCH=nnnn) at the start, the value is returned. The third  ar-
+       gument  should  point  to a uint32_t integer. If no such value has been
+       set, the call to pcre2_pattern_info() returns the error PCRE2_ERROR_UN-
+       SET. Note that this limit will only be used during matching  if  it  is
+       less  than  the limit set or defaulted by the caller of the match func-
+       tion.
+
+         PCRE2_INFO_MAXLOOKBEHIND
+
+       A lookbehind assertion moves back a certain number of  characters  (not
+       code  units)  when  it starts to process each of its branches. This re-
+       quest returns the largest of these backward moves. The  third  argument
+       should point to a uint32_t integer. The simple assertions \b and \B re-
+       quire  a one-character lookbehind and cause PCRE2_INFO_MAXLOOKBEHIND to
+       return 1 in the absence of anything longer. \A also  registers  a  one-
+       character  lookbehind, though it does not actually inspect the previous
+       character.
+
+       Note that this information is useful for multi-segment matching only if
+       the pattern contains no nested lookbehinds. For  example,  the  pattern
+       (?<=a(?<=ba)c)  returns  a  maximum  lookbehind  of  2,  but when it is
+       processed, the first lookbehind moves back by two  characters,  matches
+       one  character, then the nested lookbehind also moves back by two char-
+       acters. This puts the matching point three characters earlier  than  it
+       was  at the start.  PCRE2_INFO_MAXLOOKBEHIND is really only useful as a
+       debugging tool. See the pcre2partial documentation for a discussion  of
+       multi-segment matching.
+
+         PCRE2_INFO_MINLENGTH
+
+       If  a  minimum  length  for  matching subject strings was computed, its
+       value is returned. Otherwise the returned value is 0. This value is not
+       computed when PCRE2_NO_START_OPTIMIZE is set. The value is a number  of
+       characters,  which in UTF mode may be different from the number of code
+       units. The third argument should point  to  a  uint32_t  variable.  The
+       value  is a lower bound to the length of any matching string. There may
+       not be any strings of that length that do  actually  match,  but  every
+       string that does match is at least that long.
+
+         PCRE2_INFO_NAMECOUNT
+         PCRE2_INFO_NAMEENTRYSIZE
+         PCRE2_INFO_NAMETABLE
+
+       PCRE2 supports the use of named as well as numbered capturing parenthe-
+       ses.  The names are just an additional way of identifying the parenthe-
+       ses, which still acquire numbers. Several convenience functions such as
+       pcre2_substring_get_byname() are provided for extracting captured  sub-
+       strings  by  name. It is also possible to extract the data directly, by
+       first converting the name to a number in order to  access  the  correct
+       pointers  in the output vector (described with pcre2_match() below). To
+       do the conversion, you need to use the name-to-number map, which is de-
+       scribed by these three values.
+
+       The map consists of a number of  fixed-size  entries.  PCRE2_INFO_NAME-
+       COUNT  gives  the number of entries, and PCRE2_INFO_NAMEENTRYSIZE gives
+       the size of each entry in code units; both of these return  a  uint32_t
+       value. The entry size depends on the length of the longest name.
+
+       PCRE2_INFO_NAMETABLE returns a pointer to the first entry of the table.
+       This is a PCRE2_SPTR pointer to a block of code units. In the 8-bit li-
+       brary,  the first two bytes of each entry are the number of the captur-
+       ing parenthesis, most significant byte first. In  the  16-bit  library,
+       the  pointer  points  to 16-bit code units, the first of which contains
+       the parenthesis number. In the 32-bit library, the  pointer  points  to
+       32-bit  code units, the first of which contains the parenthesis number.
+       The rest of the entry is the corresponding name, zero terminated.
+
+       The names are in alphabetical order. If (?| is used to create  multiple
+       capture groups with the same number, as described in the section on du-
+       plicate group numbers in the pcre2pattern page, the groups may be given
+       the  same  name,  but  there  is only one entry in the table. Different
+       names for groups of the same number are not permitted.
+
+       Duplicate names for capture groups with different numbers  are  permit-
+       ted, but only if PCRE2_DUPNAMES is set. They appear in the table in the
+       order  in  which  they were found in the pattern. In the absence of (?|
+       this is the order of increasing number; when (?| is used  this  is  not
+       necessarily  the  case because later capture groups may have lower num-
+       bers.
+
+       As a simple example of the name/number table,  consider  the  following
+       pattern  after  compilation by the 8-bit library (assume PCRE2_EXTENDED
+       is set, so white space - including newlines - is ignored):
+
+         (? (?(\d\d)?\d\d) -
+         (?\d\d) - (?\d\d) )
+
+       There are four named capture groups, so the table has four entries, and
+       each entry in the table is eight bytes long. The table is  as  follows,
+       with non-printing bytes shows in hexadecimal, and undefined bytes shown
+       as ??:
+
+         00 01 d  a  t  e  00 ??
+         00 05 d  a  y  00 ?? ??
+         00 04 m  o  n  t  h  00
+         00 02 y  e  a  r  00 ??
+
+       When  writing  code to extract data from named capture groups using the
+       name-to-number map, remember that the length of the entries  is  likely
+       to be different for each compiled pattern.
+
+         PCRE2_INFO_NEWLINE
+
+       The output is one of the following uint32_t values:
+
+         PCRE2_NEWLINE_CR       Carriage return (CR)
+         PCRE2_NEWLINE_LF       Linefeed (LF)
+         PCRE2_NEWLINE_CRLF     Carriage return, linefeed (CRLF)
+         PCRE2_NEWLINE_ANY      Any Unicode line ending
+         PCRE2_NEWLINE_ANYCRLF  Any of CR, LF, or CRLF
+         PCRE2_NEWLINE_NUL      The NUL character (binary zero)
+
+       This identifies the character sequence that will be recognized as mean-
+       ing "newline" while matching.
+
+         PCRE2_INFO_SIZE
+
+       Return  the  size  of  the compiled pattern in bytes (for all three li-
+       braries). The third argument should point to a  size_t  variable.  This
+       value  includes  the  size  of the general data block that precedes the
+       code units of the compiled pattern itself. The value that is used  when
+       pcre2_compile()  is  getting memory in which to place the compiled pat-
+       tern may be slightly larger than the value returned by this option, be-
+       cause there are cases where the code that calculates the  size  has  to
+       over-estimate.  Processing a pattern with the JIT compiler does not al-
+       ter the value returned by this option.
+
+
+INFORMATION ABOUT A PATTERN'S CALLOUTS
+
+       int pcre2_callout_enumerate(const pcre2_code *code,
+         int (*callback)(pcre2_callout_enumerate_block *, void *),
+         void *user_data);
+
+       A script language that supports the use of string arguments in callouts
+       might like to scan all the callouts in a  pattern  before  running  the
+       match. This can be done by calling pcre2_callout_enumerate(). The first
+       argument  is  a  pointer  to a compiled pattern, the second points to a
+       callback function, and the third is arbitrary user data.  The  callback
+       function  is  called  for  every callout in the pattern in the order in
+       which they appear. Its first argument is a pointer to a callout enumer-
+       ation block, and its second argument is the user_data  value  that  was
+       passed  to  pcre2_callout_enumerate(). The contents of the callout enu-
+       meration block are described in the pcre2callout  documentation,  which
+       also gives further details about callouts.
+
+
+SERIALIZATION AND PRECOMPILING
+
+       It  is possible to save compiled patterns on disc or elsewhere, and re-
+       load them later, subject to a number of restrictions. The host on which
+       the patterns are reloaded must be running the same  version  of  PCRE2,
+       with  the same code unit width, and must also have the same endianness,
+       pointer width, and PCRE2_SIZE type. Before  compiled  patterns  can  be
+       saved, they must be converted to a "serialized" form, which in the case
+       of PCRE2 is really just a bytecode dump.  The functions whose names be-
+       gin with pcre2_serialize_ are used for converting to and from the seri-
+       alized  form.  They  are described in the pcre2serialize documentation.
+       Note that PCRE2 serialization does not convert compiled patterns to  an
+       abstract format like Java or .NET serialization.
+
+
+THE MATCH DATA BLOCK
+
+       pcre2_match_data *pcre2_match_data_create(uint32_t ovecsize,
+         pcre2_general_context *gcontext);
+
+       pcre2_match_data *pcre2_match_data_create_from_pattern(
+         const pcre2_code *code, pcre2_general_context *gcontext);
+
+       void pcre2_match_data_free(pcre2_match_data *match_data);
+
+       Information  about  a  successful  or unsuccessful match is placed in a
+       match data block, which is an opaque  structure  that  is  accessed  by
+       function  calls.  In particular, the match data block contains a vector
+       of offsets into the subject string that define the matched parts of the
+       subject. This is known as the ovector.
+
+       Before calling pcre2_match(), pcre2_dfa_match(),  or  pcre2_jit_match()
+       you must create a match data block by calling one of the creation func-
+       tions  above.  For pcre2_match_data_create(), the first argument is the
+       number of pairs of offsets in the ovector.
+
+       When using pcre2_match(), one pair of offsets is required  to  identify
+       the  string that matched the whole pattern, with an additional pair for
+       each captured substring. For example, a value of 4 creates enough space
+       to record the matched portion of the subject plus three  captured  sub-
+       strings.
+
+       When  using  pcre2_dfa_match() there may be multiple matched substrings
+       of different lengths at the same point  in  the  subject.  The  ovector
+       should be made large enough to hold as many as are expected.
+
+       A  minimum  of at least 1 pair is imposed by pcre2_match_data_create(),
+       so it is always possible to return the overall matched  string  in  the
+       case   of   pcre2_match()   or   the  longest  match  in  the  case  of
+       pcre2_dfa_match(). The maximum number of pairs is 65535; if  the  first
+       argument  of  pcre2_match_data_create()  is greater than this, 65535 is
+       used.
+
+       The second argument of pcre2_match_data_create() is a pointer to a gen-
+       eral context, which can specify custom memory management for  obtaining
+       the memory for the match data block. If you are not using custom memory
+       management, pass NULL, which causes malloc() to be used.
+
+       For  pcre2_match_data_create_from_pattern(),  the  first  argument is a
+       pointer to a compiled pattern. The ovector is created to be exactly the
+       right size to hold all the substrings  a  pattern  might  capture  when
+       matched using pcre2_match(). You should not use this call when matching
+       with  pcre2_dfa_match().  The  second  argument is again a pointer to a
+       general context, but in this case if NULL is passed, the memory is  ob-
+       tained  using the same allocator that was used for the compiled pattern
+       (custom or default).
+
+       A match data block can be used many times, with the same  or  different
+       compiled  patterns. You can extract information from a match data block
+       after a match operation has finished,  using  functions  that  are  de-
+       scribed in the sections on matched strings and other match data below.
+
+       When  a  call  of  pcre2_match()  fails, valid data is available in the
+       match block only  when  the  error  is  PCRE2_ERROR_NOMATCH,  PCRE2_ER-
+       ROR_PARTIAL,  or  one of the error codes for an invalid UTF string. Ex-
+       actly what is available depends on the error, and is detailed below.
+
+       When one of the matching functions is called, pointers to the  compiled
+       pattern  and the subject string are set in the match data block so that
+       they can be referenced by the extraction functions after  a  successful
+       match. After running a match, you must not free a compiled pattern or a
+       subject  string until after all operations on the match data block (for
+       that match) have taken place,  unless,  in  the  case  of  the  subject
+       string,  you  have used the PCRE2_COPY_MATCHED_SUBJECT option, which is
+       described in the section entitled "Option bits for  pcre2_match()"  be-
+       low.
+
+       When  a match data block itself is no longer needed, it should be freed
+       by calling pcre2_match_data_free(). If this function is called  with  a
+       NULL argument, it returns immediately, without doing anything.
+
+
+MEMORY USE FOR MATCH DATA BLOCKS
+
+       PCRE2_SIZE pcre2_get_match_data_size(pcre2_match_data *match_data);
+
+       PCRE2_SIZE pcre2_get_match_data_heapframes_size(
+         pcre2_match_data *match_data);
+
+       The  size of a match data block depends on the size of the ovector that
+       it contains. The function pcre2_get_match_data_size() returns the size,
+       in bytes, of the block that is its argument.
+
+       When pcre2_match() runs interpretively (that is, without using JIT), it
+       makes use of a vector of data frames for remembering backtracking posi-
+       tions.  The size of each individual frame depends on the number of cap-
+       turing parentheses in the  pattern  and  can  be  obtained  by  calling
+       pcre2_pattern_info() with the PCRE2_INFO_FRAMESIZE option (see the sec-
+       tion entitled "Information about a compiled pattern" above).
+
+       Heap  memory is used for the frames vector; if the initial memory block
+       turns out to be too small during  matching,  it  is  automatically  ex-
+       panded.  When  pcre2_match()  returns, the memory is not freed, but re-
+       mains attached to the match data  block,  for  use  by  any  subsequent
+       matches  that  use  the  same block. It is automatically freed when the
+       match data block itself is freed.
+
+       You can find the current size of the frames vector that  a  match  data
+       block  owns  by  calling  pcre2_get_match_data_heapframes_size(). For a
+       newly created match data block the size will be  zero.  Some  types  of
+       match may require a lot of frames and thus a large vector; applications
+       that run in environments where memory is constrained can check this and
+       free the match data block if the heap frames vector has become too big.
+
+
+MATCHING A PATTERN: THE TRADITIONAL FUNCTION
+
+       int pcre2_match(const pcre2_code *code, PCRE2_SPTR subject,
+         PCRE2_SIZE length, PCRE2_SIZE startoffset,
+         uint32_t options, pcre2_match_data *match_data,
+         pcre2_match_context *mcontext);
+
+       The  function pcre2_match() is called to match a subject string against
+       a compiled pattern, which is passed in the code argument. You can  call
+       pcre2_match() with the same code argument as many times as you like, in
+       order  to  find multiple matches in the subject string or to match dif-
+       ferent subject strings with the same pattern.
+
+       This function is the main matching facility of the library, and it  op-
+       erates  in  a Perl-like manner. For specialist use there is also an al-
+       ternative matching function, which is described below  in  the  section
+       about the pcre2_dfa_match() function.
+
+       Here is an example of a simple call to pcre2_match():
+
+         pcre2_match_data *md = pcre2_match_data_create(4, NULL);
+         int rc = pcre2_match(
+           re,             /* result of pcre2_compile() */
+           "some string",  /* the subject string */
+           11,             /* the length of the subject string */
+           0,              /* start at offset 0 in the subject */
+           0,              /* default options */
+           md,             /* the match data block */
+           NULL);          /* a match context; NULL means use defaults */
+
+       If  the  subject  string is zero-terminated, the length can be given as
+       PCRE2_ZERO_TERMINATED. A match context must be provided if certain less
+       common matching parameters are to be changed. For details, see the sec-
+       tion on the match context above.
+
+   The string to be matched by pcre2_match()
+
+       The subject string is passed to pcre2_match() as a pointer in  subject,
+       a  length  in  length, and a starting offset in startoffset. The length
+       and offset are in code units, not characters.  That  is,  they  are  in
+       bytes  for the 8-bit library, 16-bit code units for the 16-bit library,
+       and 32-bit code units for the 32-bit library, whether or not  UTF  pro-
+       cessing is enabled. As a special case, if subject is NULL and length is
+       zero,  the  subject is assumed to be an empty string. If length is non-
+       zero, an error occurs if subject is NULL.
+
+       If startoffset is greater than the length of the subject, pcre2_match()
+       returns PCRE2_ERROR_BADOFFSET. When the starting offset  is  zero,  the
+       search  for a match starts at the beginning of the subject, and this is
+       by far the most common case. In UTF-8 or UTF-16 mode, the starting off-
+       set must point to the start of a character, or to the end of  the  sub-
+       ject  (in  UTF-32 mode, one code unit equals one character, so all off-
+       sets are valid). Like the pattern string, the subject may  contain  bi-
+       nary zeros.
+
+       A  non-zero  starting offset is useful when searching for another match
+       in the same subject by calling pcre2_match()  again  after  a  previous
+       success.   Setting  startoffset  differs  from passing over a shortened
+       string and setting PCRE2_NOTBOL in the case of a  pattern  that  begins
+       with any kind of lookbehind. For example, consider the pattern
+
+         \Biss\B
+
+       which  finds  occurrences  of "iss" in the middle of words. (\B matches
+       only if the current position in the subject is not  a  word  boundary.)
+       When   applied   to   the   string  "Mississippi"  the  first  call  to
+       pcre2_match() finds the first occurrence. If  pcre2_match()  is  called
+       again with just the remainder of the subject, namely "issippi", it does
+       not  match,  because  \B  is  always false at the start of the subject,
+       which is deemed to be a word boundary.  However,  if  pcre2_match()  is
+       passed the entire string again, but with startoffset set to 4, it finds
+       the  second  occurrence  of "iss" because it is able to look behind the
+       starting point to discover that it is preceded by a letter.
+
+       Finding all the matches in a subject is tricky  when  the  pattern  can
+       match an empty string. It is possible to emulate Perl's /g behaviour by
+       first   trying   the   match   again  at  the  same  offset,  with  the
+       PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED options,  and  then  if  that
+       fails,  advancing  the  starting  offset  and  trying an ordinary match
+       again. There is some code that demonstrates  how  to  do  this  in  the
+       pcre2demo  sample  program. In the most general case, you have to check
+       to see if the newline convention recognizes CRLF as a newline,  and  if
+       so,  and the current character is CR followed by LF, advance the start-
+       ing offset by two characters instead of one.
+
+       If a non-zero starting offset is passed when the pattern is anchored, a
+       single attempt to match at the given offset is made. This can only suc-
+       ceed if the pattern does not require the match to be at  the  start  of
+       the  subject.  In other words, the anchoring must be the result of set-
+       ting the PCRE2_ANCHORED option or the use of .* with PCRE2_DOTALL,  not
+       by starting the pattern with ^ or \A.
+
+   Option bits for pcre2_match()
+
+       The unused bits of the options argument for pcre2_match() must be zero.
+       The    only    bits    that    may    be    set   are   PCRE2_ANCHORED,
+       PCRE2_COPY_MATCHED_SUBJECT, PCRE2_DISABLE_RECURSELOOP_CHECK,  PCRE2_EN-
+       DANCHORED,       PCRE2_NOTBOL,       PCRE2_NOTEOL,      PCRE2_NOTEMPTY,
+       PCRE2_NOTEMPTY_ATSTART,  PCRE2_NO_JIT,  PCRE2_NO_UTF_CHECK,  PCRE2_PAR-
+       TIAL_HARD, and PCRE2_PARTIAL_SOFT.  Their action is described below.
+
+       Setting  PCRE2_ANCHORED  or PCRE2_ENDANCHORED at match time is not sup-
+       ported by the just-in-time (JIT) compiler. If it is set,  JIT  matching
+       is  disabled  and  the  interpretive  code  in  pcre2_match()  is  run.
+       PCRE2_DISABLE_RECURSELOOP_CHECK is  ignored  by  JIT,  but  apart  from
+       PCRE2_NO_JIT  (obviously),  the remaining options are supported for JIT
+       matching.
+
+         PCRE2_ANCHORED
+
+       The PCRE2_ANCHORED option limits pcre2_match() to matching at the first
+       matching position. If a pattern was compiled  with  PCRE2_ANCHORED,  or
+       turned  out to be anchored by virtue of its contents, it cannot be made
+       unachored at matching time. Note that setting the option at match  time
+       disables JIT matching.
+
+         PCRE2_COPY_MATCHED_SUBJECT
+
+       By  default,  a  pointer to the subject is remembered in the match data
+       block so that, after a successful match, it can be  referenced  by  the
+       substring  extraction  functions.  This means that the subject's memory
+       must not be freed until all such operations are complete. For some  ap-
+       plications  where the lifetime of the subject string is not guaranteed,
+       it may be necessary to make a copy of the subject  string,  but  it  is
+       wasteful  to do this unless the match is successful. After a successful
+       match, if PCRE2_COPY_MATCHED_SUBJECT is set, the subject is copied  and
+       the  new  pointer  is remembered in the match data block instead of the
+       original subject pointer. The memory allocator that was  used  for  the
+       match  block  itself  is  used.  The  copy  is automatically freed when
+       pcre2_match_data_free() is called to free the match data block.  It  is
+       also automatically freed if the match data block is re-used for another
+       match operation.
+
+         PCRE2_DISABLE_RECURSELOOP_CHECK
+
+       This  option  is relevant only to pcre2_match() for interpretive match-
+       ing.   It  is  ignored  when  JIT  is  used,  and  is   forbidden   for
+       pcre2_dfa_match().
+
+       The use of recursion in patterns can lead to infinite loops. In the in-
+       terpretive  matcher  these  would  be eventually caught by the match or
+       heap limits, but this could take a long time and/or use a lot of memory
+       if the limits are large. There is therefore a check  at  the  start  of
+       each  recursion.   If  the  same  group is still active from a previous
+       call, and the current subject pointer is the same  as  it  was  at  the
+       start  of  that group, and the furthest inspected character of the sub-
+       ject has not changed, an error is generated.
+
+       There are rare cases of matches that would complete,  but  nevertheless
+       trigger  this  error.  This  option  disables the check. It is provided
+       mainly for testing when comparing JIT and interpretive behaviour.
+
+         PCRE2_ENDANCHORED
+
+       If the PCRE2_ENDANCHORED option is set, any string  that  pcre2_match()
+       matches  must be right at the end of the subject string. Note that set-
+       ting the option at match time disables JIT matching.
+
+         PCRE2_NOTBOL
+
+       This option specifies that first character of the subject string is not
+       the beginning of a line, so the  circumflex  metacharacter  should  not
+       match  before  it.  Setting  this without having set PCRE2_MULTILINE at
+       compile time causes circumflex never to match. This option affects only
+       the behaviour of the circumflex metacharacter. It does not affect \A.
+
+         PCRE2_NOTEOL
+
+       This option specifies that the end of the subject string is not the end
+       of a line, so the dollar metacharacter should not match it nor  (except
+       in  multiline mode) a newline immediately before it. Setting this with-
+       out having set PCRE2_MULTILINE at compile time causes dollar  never  to
+       match. This option affects only the behaviour of the dollar metacharac-
+       ter. It does not affect \Z or \z.
+
+         PCRE2_NOTEMPTY
+
+       An empty string is not considered to be a valid match if this option is
+       set.  If  there are alternatives in the pattern, they are tried. If all
+       the alternatives match the empty string, the entire  match  fails.  For
+       example, if the pattern
+
+         a?b?
+
+       is  applied  to  a  string not beginning with "a" or "b", it matches an
+       empty string at the start of the subject. With PCRE2_NOTEMPTY set, this
+       match is not valid, so pcre2_match() searches further into  the  string
+       for occurrences of "a" or "b".
+
+         PCRE2_NOTEMPTY_ATSTART
+
+       This  is  like PCRE2_NOTEMPTY, except that it locks out an empty string
+       match only at the first matching position, that is, at the start of the
+       subject plus the starting offset. An empty string match  later  in  the
+       subject is permitted.  If the pattern is anchored, such a match can oc-
+       cur only if the pattern contains \K.
+
+         PCRE2_NO_JIT
+
+       By   default,   if   a  pattern  has  been  successfully  processed  by
+       pcre2_jit_compile(), JIT is automatically used  when  pcre2_match()  is
+       called  with  options  that JIT supports. Setting PCRE2_NO_JIT disables
+       the use of JIT; it forces matching to be done by the interpreter.
+
+         PCRE2_NO_UTF_CHECK
+
+       When PCRE2_UTF is set at compile time, the validity of the subject as a
+       UTF  string  is  checked  unless  PCRE2_NO_UTF_CHECK   is   passed   to
+       pcre2_match() or PCRE2_MATCH_INVALID_UTF was passed to pcre2_compile().
+       The latter special case is discussed in detail in the pcre2unicode doc-
+       umentation.
+
+       In  the default case, if a non-zero starting offset is given, the check
+       is applied only to that part of the subject  that  could  be  inspected
+       during  matching,  and there is a check that the starting offset points
+       to the first code unit of a character or to the end of the subject.  If
+       there  are no lookbehind assertions in the pattern, the check starts at
+       the starting offset.  Otherwise, it starts at the length of the longest
+       lookbehind before the starting offset, or at the start of  the  subject
+       if  there are not that many characters before the starting offset. Note
+       that the sequences \b and \B are one-character lookbehinds.
+
+       The check is carried out before any other processing takes place, and a
+       negative error code is returned if the check fails. There  are  several
+       UTF  error  codes  for each code unit width, corresponding to different
+       problems with the code unit sequence. There are discussions  about  the
+       validity  of  UTF-8  strings, UTF-16 strings, and UTF-32 strings in the
+       pcre2unicode documentation.
+
+       If you know that your subject is valid, and you want to skip this check
+       for performance reasons, you can set the PCRE2_NO_UTF_CHECK option when
+       calling pcre2_match(). You might want to do this  for  the  second  and
+       subsequent  calls  to pcre2_match() if you are making repeated calls to
+       find multiple matches in the same subject string.
+
+       Warning: Unless PCRE2_MATCH_INVALID_UTF was set at compile  time,  when
+       PCRE2_NO_UTF_CHECK  is  set  at match time the effect of passing an in-
+       valid string as a subject, or an invalid value of startoffset, is unde-
+       fined.  Your program may crash or loop indefinitely or give  wrong  re-
+       sults.
+
+         PCRE2_PARTIAL_HARD
+         PCRE2_PARTIAL_SOFT
+
+       These options turn on the partial matching feature. A partial match oc-
+       curs  if  the  end  of  the subject string is reached successfully, but
+       there are not enough subject characters to complete the match. In addi-
+       tion, either at least one character must have  been  inspected  or  the
+       pattern  must  contain  a  lookbehind,  or the pattern must be one that
+       could match an empty string.
+
+       If this situation arises when PCRE2_PARTIAL_SOFT  (but  not  PCRE2_PAR-
+       TIAL_HARD) is set, matching continues by testing any remaining alterna-
+       tives.  Only  if  no complete match can be found is PCRE2_ERROR_PARTIAL
+       returned instead of PCRE2_ERROR_NOMATCH.  In  other  words,  PCRE2_PAR-
+       TIAL_SOFT  specifies  that  the  caller is prepared to handle a partial
+       match, but only if no complete match can be found.
+
+       If PCRE2_PARTIAL_HARD is set, it overrides PCRE2_PARTIAL_SOFT. In  this
+       case,  if  a  partial match is found, pcre2_match() immediately returns
+       PCRE2_ERROR_PARTIAL, without considering  any  other  alternatives.  In
+       other words, when PCRE2_PARTIAL_HARD is set, a partial match is consid-
+       ered to be more important that an alternative complete match.
+
+       There is a more detailed discussion of partial and multi-segment match-
+       ing, with examples, in the pcre2partial documentation.
+
+
+NEWLINE HANDLING WHEN MATCHING
+
+       When  PCRE2 is built, a default newline convention is set; this is usu-
+       ally the standard convention for the operating system. The default  can
+       be  overridden  in a compile context by calling pcre2_set_newline(). It
+       can also be overridden by starting a pattern string with, for  example,
+       (*CRLF),  as  described  in  the  section on newline conventions in the
+       pcre2pattern page. During matching, the newline choice affects the  be-
+       haviour  of the dot, circumflex, and dollar metacharacters. It may also
+       alter the way the match starting position is  advanced  after  a  match
+       failure for an unanchored pattern.
+
+       When PCRE2_NEWLINE_CRLF, PCRE2_NEWLINE_ANYCRLF, or PCRE2_NEWLINE_ANY is
+       set  as  the  newline convention, and a match attempt for an unanchored
+       pattern fails when the current starting position is at a CRLF sequence,
+       and the pattern contains no explicit matches for CR or  LF  characters,
+       the  match  position  is  advanced by two characters instead of one, in
+       other words, to after the CRLF.
+
+       The above rule is a compromise that makes the most common cases work as
+       expected. For example, if the pattern is .+A (and the PCRE2_DOTALL  op-
+       tion  is  not set), it does not match the string "\r\nA" because, after
+       failing at the start, it skips both the CR and the LF before  retrying.
+       However,  the  pattern  [\r\n]A does match that string, because it con-
+       tains an explicit CR or LF reference, and so advances only by one char-
+       acter after the first failure.
+
+       An explicit match for CR of LF is either a literal appearance of one of
+       those characters in the pattern, or one of the \r or \n  or  equivalent
+       octal or hexadecimal escape sequences. Implicit matches such as [^X] do
+       not  count, nor does \s, even though it includes CR and LF in the char-
+       acters that it matches.
+
+       Notwithstanding the above, anomalous effects may still occur when  CRLF
+       is a valid newline sequence and explicit \r or \n escapes appear in the
+       pattern.
+
+
+HOW PCRE2_MATCH() RETURNS A STRING AND CAPTURED SUBSTRINGS
+
+       uint32_t pcre2_get_ovector_count(pcre2_match_data *match_data);
+
+       PCRE2_SIZE *pcre2_get_ovector_pointer(pcre2_match_data *match_data);
+
+       In  general, a pattern matches a certain portion of the subject, and in
+       addition, further substrings from the subject  may  be  picked  out  by
+       parenthesized  parts  of  the  pattern.  Following the usage in Jeffrey
+       Friedl's book, this is called "capturing"  in  what  follows,  and  the
+       phrase  "capture  group" (Perl terminology) is used for a fragment of a
+       pattern that picks out a substring. PCRE2 supports several other  kinds
+       of parenthesized group that do not cause substrings to be captured. The
+       pcre2_pattern_info()  function can be used to find out how many capture
+       groups there are in a compiled pattern.
+
+       You can use auxiliary functions for accessing  captured  substrings  by
+       number or by name, as described in sections below.
+
+       Alternatively, you can make direct use of the vector of PCRE2_SIZE val-
+       ues,  called  the  ovector,  which  contains  the  offsets  of captured
+       strings.  It  is  part  of  the  match  data   block.    The   function
+       pcre2_get_ovector_pointer()  returns  the  address  of the ovector, and
+       pcre2_get_ovector_count() returns the number of pairs of values it con-
+       tains.
+
+       Within the ovector, the first in each pair of values is set to the off-
+       set of the first code unit of a substring, and the second is set to the
+       offset of the first code unit after the end of a substring. These  val-
+       ues  are always code unit offsets, not character offsets. That is, they
+       are byte offsets in the 8-bit library, 16-bit offsets in the 16-bit li-
+       brary, and 32-bit offsets in the 32-bit library.
+
+       After a partial match  (error  return  PCRE2_ERROR_PARTIAL),  only  the
+       first  pair  of  offsets  (that is, ovector[0] and ovector[1]) are set.
+       They identify the part of the subject that was partially  matched.  See
+       the pcre2partial documentation for details of partial matching.
+
+       After  a  fully  successful match, the first pair of offsets identifies
+       the portion of the subject string that was matched by the  entire  pat-
+       tern.  The  next  pair is used for the first captured substring, and so
+       on. The value returned by pcre2_match() is one more  than  the  highest
+       numbered  pair  that  has been set. For example, if two substrings have
+       been captured, the returned value is 3. If there are no  captured  sub-
+       strings, the return value from a successful match is 1, indicating that
+       just the first pair of offsets has been set.
+
+       If  a  pattern uses the \K escape sequence within a positive assertion,
+       the reported start of a successful match can be greater than the end of
+       the match.  For example, if the pattern  (?=ab\K)  is  matched  against
+       "ab", the start and end offset values for the match are 2 and 0.
+
+       If  a  capture group is matched repeatedly within a single match opera-
+       tion, it is the last portion of the subject that it matched that is re-
+       turned.
+
+       If the ovector is too small to hold all the captured substring offsets,
+       as much as possible is filled in, and the function returns a  value  of
+       zero.  If captured substrings are not of interest, pcre2_match() may be
+       called with a match data block whose ovector is of minimum length (that
+       is, one pair).
+
+       It is possible for capture group number n+1 to match some part  of  the
+       subject  when  group  n  has  not been used at all. For example, if the
+       string "abc" is matched against the pattern (a|(z))(bc) the return from
+       the function is 4, and groups 1 and 3 are matched, but 2 is  not.  When
+       this  happens,  both values in the offset pairs corresponding to unused
+       groups are set to PCRE2_UNSET.
+
+       Offset values that correspond to unused groups at the end  of  the  ex-
+       pression  are also set to PCRE2_UNSET. For example, if the string "abc"
+       is matched against the pattern (abc)(x(yz)?)? groups 2 and  3  are  not
+       matched.  The  return  from the function is 2, because the highest used
+       capture group number is 1. The offsets for the second and third capture
+       groups (assuming the vector is large enough,  of  course)  are  set  to
+       PCRE2_UNSET.
+
+       Elements in the ovector that do not correspond to capturing parentheses
+       in the pattern are never changed. That is, if a pattern contains n cap-
+       turing parentheses, no more than ovector[0] to ovector[2n+1] are set by
+       pcre2_match().  The  other  elements retain whatever values they previ-
+       ously had. After a failed match attempt, the contents  of  the  ovector
+       are unchanged.

+OTHER INFORMATION ABOUT A MATCH

+
+       PCRE2_SIZE pcre2_get_startchar(pcre2_match_data *match_data);
+
+       As  well as the offsets in the ovector, other information about a match
+       is retained in the match data block and can be retrieved by  the  above
+       functions  in  appropriate  circumstances.  If they are called at other
+       times, the result is undefined.
+
+       After a successful match, a partial match (PCRE2_ERROR_PARTIAL),  or  a
+       failure  to  match (PCRE2_ERROR_NOMATCH), a mark name may be available.
+       The function pcre2_get_mark() can be called to access this name,  which
+       can  be  specified  in  the  pattern by any of the backtracking control
+       verbs, not just (*MARK). The same function applies to all the verbs. It
+       returns a pointer to the zero-terminated name, which is within the com-
+       piled pattern. If no name is available, NULL is returned. The length of
+       the name (excluding the terminating zero) is stored in  the  code  unit
+       that  precedes  the name. You should use this length instead of relying
+       on the terminating zero if the name might contain a binary zero.
+
+       After a successful match, the name that is returned is  the  last  mark
+       name encountered on the matching path through the pattern. Instances of
+       backtracking  verbs  without  names do not count. Thus, for example, if
+       the matching path contains (*MARK:A)(*PRUNE), the name "A" is returned.
+       After a "no match" or a partial match, the last encountered name is re-
+       turned. For example, consider this pattern:
+
+         ^(*MARK:A)((*MARK:B)a|b)c
+
+       When it matches "bc", the returned name is A. The B mark is  "seen"  in
+       the  first  branch of the group, but it is not on the matching path. On
+       the other hand, when this pattern fails to  match  "bx",  the  returned
+       name is B.
+
+       Warning:  By  default, certain start-of-match optimizations are used to
+       give a fast "no match" result in some situations. For example,  if  the
+       anchoring  is removed from the pattern above, there is an initial check
+       for the presence of "c" in the subject before running the matching  en-
+       gine. This check fails for "bx", causing a match failure without seeing
+       any  marks. You can disable the start-of-match optimizations by setting
+       the PCRE2_NO_START_OPTIMIZE option for pcre2_compile() or  by  starting
+       the pattern with (*NO_START_OPT).
+
+       After  a  successful  match, a partial match, or one of the invalid UTF
+       errors (for example, PCRE2_ERROR_UTF8_ERR5), pcre2_get_startchar()  can
+       be called. After a successful or partial match it returns the code unit
+       offset  of  the character at which the match started. For a non-partial
+       match, this can be different to the value of ovector[0] if the  pattern
+       contains  the  \K escape sequence. After a partial match, however, this
+       value is always the same as ovector[0] because \K does not  affect  the
+       result of a partial match.
+
+       After  a UTF check failure, pcre2_get_startchar() can be used to obtain
+       the code unit offset of the invalid UTF character. Details are given in
+       the pcre2unicode page.
+
+
+ERROR RETURNS FROM pcre2_match()
+
+       If pcre2_match() fails, it returns a negative number. This can be  con-
+       verted  to a text string by calling the pcre2_get_error_message() func-
+       tion (see "Obtaining a textual error message" below).   Negative  error
+       codes  are  also  returned  by other functions, and are documented with
+       them. The codes are given names in the header file. If UTF checking  is
+       in force and an invalid UTF subject string is detected, one of a number
+       of  UTF-specific negative error codes is returned. Details are given in
+       the pcre2unicode page. The following are the other errors that  may  be
+       returned by pcre2_match():
+
+         PCRE2_ERROR_NOMATCH
+
+       The subject string did not match the pattern.
+
+         PCRE2_ERROR_PARTIAL
+
+       The  subject  string did not match, but it did match partially. See the
+       pcre2partial documentation for details of partial matching.
+
+         PCRE2_ERROR_BADMAGIC
+
+       PCRE2 stores a 4-byte "magic number" at the start of the compiled code,
+       to catch the case when it is passed a junk pointer. This is  the  error
+       that is returned when the magic number is not present.
+
+         PCRE2_ERROR_BADMODE
+
+       This  error is given when a compiled pattern is passed to a function in
+       a library of a different code unit width, for example, a  pattern  com-
+       piled  by  the  8-bit  library  is passed to a 16-bit or 32-bit library
+       function.
+
+         PCRE2_ERROR_BADOFFSET
+
+       The value of startoffset was greater than the length of the subject.
+
+         PCRE2_ERROR_BADOPTION
+
+       An unrecognized bit was set in the options argument.
+
+         PCRE2_ERROR_BADUTFOFFSET
+
+       The UTF code unit sequence that was passed as a subject was checked and
+       found to be valid (the PCRE2_NO_UTF_CHECK option was not set), but  the
+       value  of startoffset did not point to the beginning of a UTF character
+       or the end of the subject.
+
+         PCRE2_ERROR_CALLOUT
+
+       This error is never generated by pcre2_match() itself. It  is  provided
+       for  use  by  callout  functions  that  want  to cause pcre2_match() or
+       pcre2_callout_enumerate() to return a distinctive error code.  See  the
+       pcre2callout documentation for details.
+
+         PCRE2_ERROR_DEPTHLIMIT
+
+       The nested backtracking depth limit was reached.
+
+         PCRE2_ERROR_HEAPLIMIT
+
+       The heap limit was reached.
+
+         PCRE2_ERROR_INTERNAL
+
+       An  unexpected  internal error has occurred. This error could be caused
+       by a bug in PCRE2 or by overwriting of the compiled pattern.
+
+         PCRE2_ERROR_JIT_STACKLIMIT
+
+       This error is returned when a pattern that was successfully studied us-
+       ing JIT is being matched, but the memory available for the just-in-time
+       processing stack is not large enough. See  the  pcre2jit  documentation
+       for more details.
+
+         PCRE2_ERROR_MATCHLIMIT
+
+       The backtracking match limit was reached.
+
+         PCRE2_ERROR_NOMEMORY
+
+       Heap  memory  is  used  to  remember backtracking points. This error is
+       given when the memory allocation function (default  or  custom)  fails.
+       Note  that  a  different  error, PCRE2_ERROR_HEAPLIMIT, is given if the
+       amount of memory needed exceeds the heap limit. PCRE2_ERROR_NOMEMORY is
+       also returned if PCRE2_COPY_MATCHED_SUBJECT is set and  memory  alloca-
+       tion fails.
+
+         PCRE2_ERROR_NULL
+
+       Either the code, subject, or match_data argument was passed as NULL.
+
+         PCRE2_ERROR_RECURSELOOP
+
+       This  error  is  returned  when  pcre2_match() detects a recursion loop
+       within the pattern. Specifically, it means that either the  whole  pat-
+       tern or a capture group has been called recursively for the second time
+       at  the  same position in the subject string. Some simple patterns that
+       might do this are detected and faulted at compile time, but  more  com-
+       plicated  cases,  in particular mutual recursions between two different
+       groups, cannot be detected until matching is attempted.
+
+
+OBTAINING A TEXTUAL ERROR MESSAGE
+
+       int pcre2_get_error_message(int errorcode, PCRE2_UCHAR *buffer,
+         PCRE2_SIZE bufflen);
+
+       A text message for an error code  from  any  PCRE2  function  (compile,
+       match,  or  auxiliary)  can be obtained by calling pcre2_get_error_mes-
+       sage(). The code is passed as the first argument,  with  the  remaining
+       two  arguments  specifying  a  code  unit buffer and its length in code
+       units, into which the text message is placed. The message  is  returned
+       in  code  units  of the appropriate width for the library that is being
+       used.
+
+       The returned message is terminated with a trailing zero, and the  func-
+       tion  returns  the  number  of  code units used, excluding the trailing
+       zero. If the error number is unknown, the negative error code PCRE2_ER-
+       ROR_BADDATA is returned. If the buffer is too  small,  the  message  is
+       truncated (but still with a trailing zero), and the negative error code
+       PCRE2_ERROR_NOMEMORY  is returned.  None of the messages are very long;
+       a buffer size of 120 code units is ample.
+
+
+EXTRACTING CAPTURED SUBSTRINGS BY NUMBER
+
+       int pcre2_substring_length_bynumber(pcre2_match_data *match_data,
+         uint32_t number, PCRE2_SIZE *length);
+
+       int pcre2_substring_copy_bynumber(pcre2_match_data *match_data,
+         uint32_t number, PCRE2_UCHAR *buffer,
+         PCRE2_SIZE *bufflen);
+
+       int pcre2_substring_get_bynumber(pcre2_match_data *match_data,
+         uint32_t number, PCRE2_UCHAR **bufferptr,
+         PCRE2_SIZE *bufflen);
+
+       void pcre2_substring_free(PCRE2_UCHAR *buffer);
+
+       Captured substrings can be accessed directly by using  the  ovector  as
+       described above.  For convenience, auxiliary functions are provided for
+       extracting   captured  substrings  as  new,  separate,  zero-terminated
+       strings. A substring that contains a binary zero is correctly extracted
+       and has a further zero added on the end, but  the  result  is  not,  of
+       course, a C string.
+
+       The functions in this section identify substrings by number. The number
+       zero refers to the entire matched substring, with higher numbers refer-
+       ring  to  substrings  captured by parenthesized groups. After a partial
+       match, only substring zero is available.  An  attempt  to  extract  any
+       other  substring  gives the error PCRE2_ERROR_PARTIAL. The next section
+       describes similar functions for extracting captured substrings by name.
+
+       If a pattern uses the \K escape sequence within a  positive  assertion,
+       the reported start of a successful match can be greater than the end of
+       the  match.   For  example,  if the pattern (?=ab\K) is matched against
+       "ab", the start and end offset values for the match are  2  and  0.  In
+       this  situation,  calling  these functions with a zero substring number
+       extracts a zero-length empty string.
+
+       You can find the length in code units of a captured  substring  without
+       extracting  it  by calling pcre2_substring_length_bynumber(). The first
+       argument is a pointer to the match data block, the second is the  group
+       number,  and the third is a pointer to a variable into which the length
+       is placed. If you just want to know whether or not  the  substring  has
+       been captured, you can pass the third argument as NULL.
+
+       The  pcre2_substring_copy_bynumber()  function  copies  a captured sub-
+       string into a supplied buffer,  whereas  pcre2_substring_get_bynumber()
+       copies  it  into  new memory, obtained using the same memory allocation
+       function that was used for the match data block. The  first  two  argu-
+       ments  of  these  functions are a pointer to the match data block and a
+       capture group number.
+
+       The final arguments of pcre2_substring_copy_bynumber() are a pointer to
+       the buffer and a pointer to a variable that contains its length in code
+       units.  This is updated to contain the actual number of code units used
+       for the extracted substring, excluding the terminating zero.
+
+       For pcre2_substring_get_bynumber() the third and fourth arguments point
+       to variables that are updated with a pointer to the new memory and  the
+       number  of  code units that comprise the substring, again excluding the
+       terminating zero. When the substring is no longer  needed,  the  memory
+       should be freed by calling pcre2_substring_free().
+
+       The  return  value  from  all these functions is zero for success, or a
+       negative error code. If the pattern match  failed,  the  match  failure
+       code  is returned.  If a substring number greater than zero is used af-
+       ter a partial match, PCRE2_ERROR_PARTIAL is  returned.  Other  possible
+       error codes are:
+
+         PCRE2_ERROR_NOMEMORY
+
+       The  buffer  was  too small for pcre2_substring_copy_bynumber(), or the
+       attempt to get memory failed for pcre2_substring_get_bynumber().
+
+         PCRE2_ERROR_NOSUBSTRING
+
+       There is no substring with that number in the  pattern,  that  is,  the
+       number is greater than the number of capturing parentheses.
+
+         PCRE2_ERROR_UNAVAILABLE
+
+       The substring number, though not greater than the number of captures in
+       the pattern, is greater than the number of slots in the ovector, so the
+       substring could not be captured.
+
+         PCRE2_ERROR_UNSET
+
+       The  substring  did  not  participate in the match. For example, if the
+       pattern is (abc)|(def) and the subject is "def", and the  ovector  con-
+       tains at least two capturing slots, substring number 1 is unset.
+
+
+EXTRACTING A LIST OF ALL CAPTURED SUBSTRINGS
+
+       int pcre2_substring_list_get(pcre2_match_data *match_data,
+         PCRE2_UCHAR ***listptr, PCRE2_SIZE **lengthsptr);
+
+       void pcre2_substring_list_free(PCRE2_UCHAR **list);
+
+       The  pcre2_substring_list_get()  function  extracts  all available sub-
+       strings and builds a list of pointers to  them.  It  also  (optionally)
+       builds  a  second list that contains their lengths (in code units), ex-
+       cluding a terminating zero that is added to each of them. All  this  is
+       done in a single block of memory that is obtained using the same memory
+       allocation function that was used to get the match data block.
+
+       This  function  must be called only after a successful match. If called
+       after a partial match, the error code PCRE2_ERROR_PARTIAL is returned.
+
+       The address of the memory block is returned via listptr, which is  also
+       the start of the list of string pointers. The end of the list is marked
+       by  a  NULL pointer. The address of the list of lengths is returned via
+       lengthsptr. If your strings do not contain binary zeros and you do  not
+       therefore need the lengths, you may supply NULL as the lengthsptr argu-
+       ment  to  disable  the  creation of a list of lengths. The yield of the
+       function is zero if all went well, or PCRE2_ERROR_NOMEMORY if the  mem-
+       ory  block could not be obtained. When the list is no longer needed, it
+       should be freed by calling pcre2_substring_list_free().
+
+       If this function encounters a substring that is unset, which can happen
+       when capture group number n+1 matches some part  of  the  subject,  but
+       group  n has not been used at all, it returns an empty string. This can
+       be distinguished from a genuine zero-length substring by inspecting the
+       appropriate offset in the ovector, which contain PCRE2_UNSET for  unset
+       substrings, or by calling pcre2_substring_length_bynumber().
+
+
+EXTRACTING CAPTURED SUBSTRINGS BY NAME
+
+       int pcre2_substring_number_from_name(const pcre2_code *code,
+         PCRE2_SPTR name);
+
+       int pcre2_substring_length_byname(pcre2_match_data *match_data,
+         PCRE2_SPTR name, PCRE2_SIZE *length);
+
+       int pcre2_substring_copy_byname(pcre2_match_data *match_data,
+         PCRE2_SPTR name, PCRE2_UCHAR *buffer, PCRE2_SIZE *bufflen);
+
+       int pcre2_substring_get_byname(pcre2_match_data *match_data,
+         PCRE2_SPTR name, PCRE2_UCHAR **bufferptr, PCRE2_SIZE *bufflen);
+
+       void pcre2_substring_free(PCRE2_UCHAR *buffer);
+
+       To  extract a substring by name, you first have to find associated num-
+       ber.  For example, for this pattern:
+
+         (a+)b(?\d+)...
+
+       the number of the capture group called "xxx" is 2. If the name is known
+       to be unique (PCRE2_DUPNAMES was not set), you can find the number from
+       the name by calling pcre2_substring_number_from_name(). The first argu-
+       ment is the compiled pattern, and the second is the name. The yield  of
+       the  function  is the group number, PCRE2_ERROR_NOSUBSTRING if there is
+       no group with that name, or PCRE2_ERROR_NOUNIQUESUBSTRING if  there  is
+       more  than one group with that name.  Given the number, you can extract
+       the substring directly from the ovector, or use one of  the  "bynumber"
+       functions described above.
+
+       For  convenience,  there are also "byname" functions that correspond to
+       the "bynumber" functions, the only difference being that the second ar-
+       gument is a name instead of a number.  If  PCRE2_DUPNAMES  is  set  and
+       there are duplicate names, these functions scan all the groups with the
+       given  name,  and  return  the  captured substring from the first named
+       group that is set.
+
+       If there are no groups with the given name, PCRE2_ERROR_NOSUBSTRING  is
+       returned.  If  all  groups  with the name have numbers that are greater
+       than the number of slots in the ovector, PCRE2_ERROR_UNAVAILABLE is re-
+       turned. If there is at least one group with a slot in the ovector,  but
+       no group is found to be set, PCRE2_ERROR_UNSET is returned.
+
+       Warning: If the pattern uses the (?| feature to set up multiple capture
+       groups  with  the same number, as described in the section on duplicate
+       group numbers in the pcre2pattern page, you cannot use names to distin-
+       guish the different capture groups, because names are not  included  in
+       the  compiled  code.  The  matching process uses only numbers. For this
+       reason, the use of different names for  groups  with  the  same  number
+       causes an error at compile time.
+
+
+CREATING A NEW STRING WITH SUBSTITUTIONS
+
+       int pcre2_substitute(const pcre2_code *code, PCRE2_SPTR subject,
+         PCRE2_SIZE length, PCRE2_SIZE startoffset,
+         uint32_t options, pcre2_match_data *match_data,
+         pcre2_match_context *mcontext, PCRE2_SPTR replacement,
+         PCRE2_SIZE rlength, PCRE2_UCHAR *outputbuffer,
+         PCRE2_SIZE *outlengthptr);
+
+       This  function  optionally calls pcre2_match() and then makes a copy of
+       the subject string in outputbuffer, replacing parts that  were  matched
+       with the replacement string, whose length is supplied in rlength, which
+       can  be given as PCRE2_ZERO_TERMINATED for a zero-terminated string. As
+       a special case, if replacement is NULL and rlength  is  zero,  the  re-
+       placement  is assumed to be an empty string. If rlength is non-zero, an
+       error occurs if replacement is NULL.
+
+       There is an option (see PCRE2_SUBSTITUTE_REPLACEMENT_ONLY below) to re-
+       turn just the replacement string(s). The default action is  to  perform
+       just  one  replacement  if  the pattern matches, but there is an option
+       that requests multiple replacements  (see  PCRE2_SUBSTITUTE_GLOBAL  be-
+       low).
+
+       If  successful,  pcre2_substitute() returns the number of substitutions
+       that were carried out. This may be zero if no match was found,  and  is
+       never  greater  than one unless PCRE2_SUBSTITUTE_GLOBAL is set. A nega-
+       tive value is returned if an error is detected.
+
+       Matches in which a \K item in a lookahead in  the  pattern  causes  the
+       match  to  end  before it starts are not supported, and give rise to an
+       error return. For global replacements, matches in which \K in a lookbe-
+       hind causes the match to start earlier than the point that was  reached
+       in the previous iteration are also not supported.
+
+       The  first  seven  arguments  of pcre2_substitute() are the same as for
+       pcre2_match(), except that the partial matching options are not permit-
+       ted, and match_data may be passed as NULL, in which case a  match  data
+       block  is obtained and freed within this function, using memory manage-
+       ment functions from the match context, if provided, or else those  that
+       were used to allocate memory for the compiled code.
+
+       If  match_data is not NULL and PCRE2_SUBSTITUTE_MATCHED is not set, the
+       provided block is used for all calls to pcre2_match(), and its contents
+       afterwards are the result of the final call. For global  changes,  this
+       will always be a no-match error. The contents of the ovector within the
+       match data block may or may not have been changed.
+
+       As  well as the usual options for pcre2_match(), a number of additional
+       options can be set in the options argument of pcre2_substitute().   One
+       such  option is PCRE2_SUBSTITUTE_MATCHED. When this is set, an external
+       match_data block must be provided, and it must have already  been  used
+       for an external call to pcre2_match() with the same pattern and subject
+       arguments.  The  data in the match_data block (return code, offset vec-
+       tor) is then  used  for  the  first  substitution  instead  of  calling
+       pcre2_match()  from  within pcre2_substitute(). This allows an applica-
+       tion to check for a match before choosing to substitute, without having
+       to repeat the match.
+
+       The contents of the  externally  supplied  match  data  block  are  not
+       changed   when   PCRE2_SUBSTITUTE_MATCHED   is  set.  If  PCRE2_SUBSTI-
+       TUTE_GLOBAL is also set, pcre2_match() is called after the  first  sub-
+       stitution  to  check for further matches, but this is done using an in-
+       ternally obtained match data block, thus always  leaving  the  external
+       block unchanged.
+
+       The  code  argument is not used for matching before the first substitu-
+       tion when PCRE2_SUBSTITUTE_MATCHED is set, but  it  must  be  provided,
+       even  when  PCRE2_SUBSTITUTE_GLOBAL is not set, because it contains in-
+       formation such as the UTF setting and the number of capturing parenthe-
+       ses in the pattern.

+       The default action of pcre2_substitute() is to return  a  copy  of  the
+       subject string with matched substrings replaced. However, if PCRE2_SUB-
+       STITUTE_REPLACEMENT_ONLY  is  set,  only the replacement substrings are
+       returned. In the global case, multiple replacements are concatenated in
+       the output buffer. Substitution callouts (see below)  can  be  used  to
+       separate them if necessary.
+
+       The  outlengthptr  argument of pcre2_substitute() must point to a vari-
+       able that contains the length, in code units, of the output buffer.  If
+       the  function is successful, the value is updated to contain the length
+       in code units of the new string, excluding the trailing  zero  that  is
+       automatically added.
+
+       If  the  function is not successful, the value set via outlengthptr de-
+       pends on the type of  error.  For  syntax  errors  in  the  replacement
+       string, the value is the offset in the replacement string where the er-
+       ror  was  detected.  For  other errors, the value is PCRE2_UNSET by de-
+       fault. This includes the case of the output buffer being too small, un-
+       less PCRE2_SUBSTITUTE_OVERFLOW_LENGTH is set.
+
+       PCRE2_SUBSTITUTE_OVERFLOW_LENGTH changes what happens when  the  output
+       buffer is too small. The default action is to return PCRE2_ERROR_NOMEM-
+       ORY  immediately.  If  this  option is set, however, pcre2_substitute()
+       continues to go through the motions of matching and substituting (with-
+       out, of course, writing anything) in  order  to  compute  the  size  of
+       buffer  that  is needed. This value is passed back via the outlengthptr
+       variable, with  the  result  of  the  function  still  being  PCRE2_ER-
+       ROR_NOMEMORY.
+
+       Passing  a  buffer  size  of zero is a permitted way of finding out how
+       much memory is needed for given substitution. However, this  does  mean
+       that the entire operation is carried out twice. Depending on the appli-
+       cation,  it  may  be more efficient to allocate a large buffer and free
+       the  excess  afterwards,  instead   of   using   PCRE2_SUBSTITUTE_OVER-
+       FLOW_LENGTH.
+
+       The  replacement  string,  which  is interpreted as a UTF string in UTF
+       mode, is checked for UTF validity unless PCRE2_NO_UTF_CHECK is set.  An
+       invalid UTF replacement string causes an immediate return with the rel-
+       evant UTF error code.
+
+       If  PCRE2_SUBSTITUTE_LITERAL  is set, the replacement string is not in-
+       terpreted in any way. By default, however, a dollar character is an es-
+       cape character that can specify the insertion of characters  from  cap-
+       ture  groups  and names from (*MARK) or other control verbs in the pat-
+       tern. Dollar is the only escape character (backslash is treated as lit-
+       eral). The following forms are always recognized:
+
+         $$                  insert a dollar character
+         $ or ${}      insert the contents of group 
+         $*MARK or ${*MARK}  insert a control verb name
+
+       Either a group number or a group name  can  be  given  for  .  Curly
+       brackets  are  required only if the following character would be inter-
+       preted as part of the number or name. The number may be zero to include
+       the entire matched string.   For  example,  if  the  pattern  a(b)c  is
+       matched  with "=abc=" and the replacement string "+$1$0$1+", the result
+       is "=+babcb+=".
+
+       $*MARK inserts the name from the last encountered backtracking  control
+       verb  on the matching path that has a name. (*MARK) must always include
+       a name, but the other verbs need not.  For  example,  in  the  case  of
+       (*MARK:A)(*PRUNE) the name inserted is "A", but for (*MARK:A)(*PRUNE:B)
+       the  relevant  name is "B". This facility can be used to perform simple
+       simultaneous substitutions, as this pcre2test example shows:
+
+         /(*MARK:pear)apple|(*MARK:orange)lemon/g,replace=${*MARK}
+             apple lemon
+          2: pear orange
+
+       PCRE2_SUBSTITUTE_GLOBAL causes the function to iterate over the subject
+       string, replacing every matching substring. If this option is not  set,
+       only  the  first matching substring is replaced. The search for matches
+       takes place in the original subject string (that is, previous  replace-
+       ments  do  not  affect  it).  Iteration is implemented by advancing the
+       startoffset value for each search, which is always  passed  the  entire
+       subject string. If an offset limit is set in the match context, search-
+       ing stops when that limit is reached.
+
+       You  can  restrict  the effect of a global substitution to a portion of
+       the subject string by setting either or both of startoffset and an off-
+       set limit. Here is a pcre2test example:
+
+         /B/g,replace=!,use_offset_limit
+         ABC ABC ABC ABC\=offset=3,offset_limit=12
+          2: ABC A!C A!C ABC
+
+       When continuing with global substitutions after  matching  a  substring
+       with zero length, an attempt to find a non-empty match at the same off-
+       set is performed.  If this is not successful, the offset is advanced by
+       one character except when CRLF is a valid newline sequence and the next
+       two  characters are CR, LF. In this case, the offset is advanced by two
+       characters.
+
+       PCRE2_SUBSTITUTE_UNKNOWN_UNSET causes references to capture groups that
+       do not appear in the pattern to be treated as unset groups. This option
+       should be used with care, because it means that a typo in a group  name
+       or number no longer causes the PCRE2_ERROR_NOSUBSTRING error.
+
+       PCRE2_SUBSTITUTE_UNSET_EMPTY causes unset capture groups (including un-
+       known  groups when PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set) to be treated
+       as empty strings when inserted as described above. If  this  option  is
+       not set, an attempt to insert an unset group causes the PCRE2_ERROR_UN-
+       SET  error.  This  option  does not influence the extended substitution
+       syntax described below.
+
+       PCRE2_SUBSTITUTE_EXTENDED causes extra processing to be applied to  the
+       replacement  string.  Without this option, only the dollar character is
+       special, and only the group insertion forms  listed  above  are  valid.
+       When PCRE2_SUBSTITUTE_EXTENDED is set, two things change:
+
+       Firstly,  backslash in a replacement string is interpreted as an escape
+       character. The usual forms such as \n or \x{ddd} can be used to specify
+       particular character codes, and backslash followed by any  non-alphanu-
+       meric  character  quotes  that character. Extended quoting can be coded
+       using \Q...\E, exactly as in pattern strings.
+
+       There are also four escape sequences for forcing the case  of  inserted
+       letters.   The  insertion  mechanism has three states: no case forcing,
+       force upper case, and force lower case. The escape sequences change the
+       current state: \U and \L change to upper or lower case forcing, respec-
+       tively, and \E (when not terminating a \Q quoted sequence)  reverts  to
+       no  case  forcing. The sequences \u and \l force the next character (if
+       it is a letter) to upper or lower  case,  respectively,  and  then  the
+       state automatically reverts to no case forcing. Case forcing applies to
+       all  inserted  characters, including those from capture groups and let-
+       ters within \Q...\E quoted sequences. If either PCRE2_UTF or  PCRE2_UCP
+       was  set when the pattern was compiled, Unicode properties are used for
+       case forcing characters whose code points are greater than 127.
+
+       Note that case forcing sequences such as \U...\E do not nest. For exam-
+       ple, the result of processing "\Uaa\LBB\Ecc\E" is "AAbbcc";  the  final
+       \E  has  no  effect.  Note  also  that the PCRE2_ALT_BSUX and PCRE2_EX-
+       TRA_ALT_BSUX options do not apply to replacement strings.
+
+       The second effect of setting PCRE2_SUBSTITUTE_EXTENDED is to  add  more
+       flexibility  to  capture  group  substitution. The syntax is similar to
+       that used by Bash:
+
+         ${:-}
+         ${:+:}
+
+       As before,  may be a group number or a name. The first  form  speci-
+       fies  a  default  value. If group  is set, its value is inserted; if
+       not,  is expanded and the  result  inserted.  The  second  form
+       specifies  strings that are expanded and inserted when group  is set
+       or unset, respectively. The first form is just a  convenient  shorthand
+       for
+
+         ${:+${}:}
+
+       Backslash  can  be  used to escape colons and closing curly brackets in
+       the replacement strings. A change of the case forcing  state  within  a
+       replacement  string  remains  in  force  afterwards,  as  shown in this
+       pcre2test example:
+
+         /(some)?(body)/substitute_extended,replace=${1:+\U:\L}HeLLo
+             body
+          1: hello
+             somebody
+          1: HELLO
+
+       The PCRE2_SUBSTITUTE_UNSET_EMPTY option does not affect these  extended
+       substitutions.  However,  PCRE2_SUBSTITUTE_UNKNOWN_UNSET does cause un-
+       known groups in the extended syntax forms to be treated as unset.
+
+       If  PCRE2_SUBSTITUTE_LITERAL  is  set,  PCRE2_SUBSTITUTE_UNKNOWN_UNSET,
+       PCRE2_SUBSTITUTE_UNSET_EMPTY, and PCRE2_SUBSTITUTE_EXTENDED are irrele-
+       vant and are ignored.
+
+   Substitution errors
+
+       In  the  event of an error, pcre2_substitute() returns a negative error
+       code. Except for PCRE2_ERROR_NOMATCH (which is never returned),  errors
+       from pcre2_match() are passed straight back.
+
+       PCRE2_ERROR_NOSUBSTRING is returned for a non-existent substring inser-
+       tion, unless PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set.
+
+       PCRE2_ERROR_UNSET is returned for an unset substring insertion (includ-
+       ing  an  unknown  substring when PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set)
+       when the simple (non-extended) syntax is used and  PCRE2_SUBSTITUTE_UN-
+       SET_EMPTY is not set.
+
+       PCRE2_ERROR_NOMEMORY  is  returned  if  the  output  buffer  is not big
+       enough. If the PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option is set, the size
+       of buffer that is needed is returned via outlengthptr. Note  that  this
+       does not happen by default.
+
+       PCRE2_ERROR_NULL is returned if PCRE2_SUBSTITUTE_MATCHED is set but the
+       match_data  argument is NULL or if the subject or replacement arguments
+       are NULL. For backward compatibility reasons an exception is  made  for
+       the replacement argument if the rlength argument is also 0.
+
+       PCRE2_ERROR_BADREPLACEMENT  is  used for miscellaneous syntax errors in
+       the replacement string, with more  particular  errors  being  PCRE2_ER-
+       ROR_BADREPESCAPE (invalid escape sequence), PCRE2_ERROR_REPMISSINGBRACE
+       (closing  curly bracket not found), PCRE2_ERROR_BADSUBSTITUTION (syntax
+       error in extended group substitution),  and  PCRE2_ERROR_BADSUBSPATTERN
+       (the pattern match ended before it started or the match started earlier
+       than  the  current  position  in the subject, which can happen if \K is
+       used in an assertion).
+
+       As for all PCRE2 errors, a text message that describes the error can be
+       obtained by calling the pcre2_get_error_message()  function  (see  "Ob-
+       taining a textual error message" above).
+
+   Substitution callouts
+
+       int pcre2_set_substitute_callout(pcre2_match_context *mcontext,
+         int (*callout_function)(pcre2_substitute_callout_block *, void *),
+         void *callout_data);
+
+       The  pcre2_set_substitution_callout() function can be used to specify a
+       callout function for pcre2_substitute(). This information is passed  in
+       a match context. The callout function is called after each substitution
+       has been processed, but it can cause the replacement not to happen. The
+       callout  function is not called for simulated substitutions that happen
+       as a result of the PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option.
+
+       The first argument of the callout function is a pointer to a substitute
+       callout block structure, which contains the following fields, not  nec-
+       essarily in this order:
+
+         uint32_t    version;
+         uint32_t    subscount;
+         PCRE2_SPTR  input;
+         PCRE2_SPTR  output;
+         PCRE2_SIZE *ovector;
+         uint32_t    oveccount;
+         PCRE2_SIZE  output_offsets[2];
+
+       The  version field contains the version number of the block format. The
+       current version is 0. The version number will  increase  in  future  if
+       more  fields are added, but the intention is never to remove any of the
+       existing fields.
+
+       The subscount field is the number of the current match. It is 1 for the
+       first callout, 2 for the second, and so on. The input and output point-
+       ers are copies of the values passed to pcre2_substitute().
+
+       The ovector field points to the ovector, which contains the  result  of
+       the most recent match. The oveccount field contains the number of pairs
+       that are set in the ovector, and is always greater than zero.
+
+       The  output_offsets  vector  contains the offsets of the replacement in
+       the output string. This has already been processed for dollar  and  (if
+       requested) backslash substitutions as described above.
+
+       The  second  argument  of  the  callout function is the value passed as
+       callout_data when the function was registered. The  value  returned  by
+       the callout function is interpreted as follows:
+
+       If  the  value is zero, the replacement is accepted, and, if PCRE2_SUB-
+       STITUTE_GLOBAL is set, processing continues with a search for the  next
+       match.  If  the  value  is not zero, the current replacement is not ac-
+       cepted. If the value is greater than zero,  processing  continues  when
+       PCRE2_SUBSTITUTE_GLOBAL  is set. Otherwise (the value is less than zero
+       or PCRE2_SUBSTITUTE_GLOBAL is not set), the rest of the input is copied
+       to the output and the call to pcre2_substitute() exits,  returning  the
+       number of matches so far.
+
+
+DUPLICATE CAPTURE GROUP NAMES
+
+       int pcre2_substring_nametable_scan(const pcre2_code *code,
+         PCRE2_SPTR name, PCRE2_SPTR *first, PCRE2_SPTR *last);
+
+       When  a  pattern  is compiled with the PCRE2_DUPNAMES option, names for
+       capture groups are not required to be unique. Duplicate names  are  al-
+       ways  allowed for groups with the same number, created by using the (?|
+       feature. Indeed, if such groups are named, they are required to use the
+       same names.
+
+       Normally, patterns that use duplicate names are such that  in  any  one
+       match,  only  one of each set of identically-named groups participates.
+       An example is shown in the pcre2pattern documentation.
+
+       When  duplicates   are   present,   pcre2_substring_copy_byname()   and
+       pcre2_substring_get_byname()  return  the first substring corresponding
+       to the given name that is set. Only if none are set is  PCRE2_ERROR_UN-
+       SET  is  returned.  The pcre2_substring_number_from_name() function re-
+       turns the error PCRE2_ERROR_NOUNIQUESUBSTRING when there are  duplicate
+       names.
+
+       If  you want to get full details of all captured substrings for a given
+       name, you must use the pcre2_substring_nametable_scan()  function.  The
+       first  argument is the compiled pattern, and the second is the name. If
+       the third and fourth arguments are NULL, the function returns  a  group
+       number for a unique name, or PCRE2_ERROR_NOUNIQUESUBSTRING otherwise.
+
+       When the third and fourth arguments are not NULL, they must be pointers
+       to  variables  that are updated by the function. After it has run, they
+       point to the first and last entries in the name-to-number table for the
+       given name, and the function returns the length of each entry  in  code
+       units.  In both cases, PCRE2_ERROR_NOSUBSTRING is returned if there are
+       no entries for the given name.
+
+       The format of the name table is described above in the section entitled
+       Information about a pattern. Given all the  relevant  entries  for  the
+       name,  you  can  extract  each of their numbers, and hence the captured
+       data.
+
+
+FINDING ALL POSSIBLE MATCHES AT ONE POSITION
+
+       The traditional matching function uses a  similar  algorithm  to  Perl,
+       which  stops when it finds the first match at a given point in the sub-
+       ject. If you want to find all possible matches, or the longest possible
+       match at a given position,  consider  using  the  alternative  matching
+       function  (see  below) instead. If you cannot use the alternative func-
+       tion, you can kludge it up by making use of the callout facility, which
+       is described in the pcre2callout documentation.
+
+       What you have to do is to insert a callout right at the end of the pat-
+       tern.  When your callout function is called, extract and save the  cur-
+       rent  matched  substring.  Then return 1, which forces pcre2_match() to
+       backtrack and try other alternatives. Ultimately, when it runs  out  of
+       matches, pcre2_match() will yield PCRE2_ERROR_NOMATCH.
+
+
+MATCHING A PATTERN: THE ALTERNATIVE FUNCTION
+
+       int pcre2_dfa_match(const pcre2_code *code, PCRE2_SPTR subject,
+         PCRE2_SIZE length, PCRE2_SIZE startoffset,
+         uint32_t options, pcre2_match_data *match_data,
+         pcre2_match_context *mcontext,
+         int *workspace, PCRE2_SIZE wscount);
+
+       The  function  pcre2_dfa_match()  is  called  to match a subject string
+       against a compiled pattern, using a matching algorithm that  scans  the
+       subject string just once (not counting lookaround assertions), and does
+       not  backtrack (except when processing lookaround assertions). This has
+       different characteristics to the normal algorithm, and is not  compati-
+       ble  with  Perl.  Some  of  the features of PCRE2 patterns are not sup-
+       ported. Nevertheless, there are times when this kind of matching can be
+       useful. For a discussion of the two matching algorithms, and a list  of
+       features that pcre2_dfa_match() does not support, see the pcre2matching
+       documentation.
+
+       The  arguments  for  the pcre2_dfa_match() function are the same as for
+       pcre2_match(), plus two extras. The ovector within the match data block
+       is used in a different way, and this is described below. The other com-
+       mon arguments are used in the same way as for pcre2_match(),  so  their
+       description is not repeated here.
+
+       The  two  additional  arguments provide workspace for the function. The
+       workspace vector should contain at least 20 elements. It  is  used  for
+       keeping  track  of  multiple paths through the pattern tree. More work-
+       space is needed for patterns and subjects where there are a lot of  po-
+       tential matches.
+
+       Here is an example of a simple call to pcre2_dfa_match():
+
+         int wspace[20];
+         pcre2_match_data *md = pcre2_match_data_create(4, NULL);
+         int rc = pcre2_dfa_match(
+           re,             /* result of pcre2_compile() */
+           "some string",  /* the subject string */
+           11,             /* the length of the subject string */
+           0,              /* start at offset 0 in the subject */
+           0,              /* default options */
+           md,             /* the match data block */
+           NULL,           /* a match context; NULL means use defaults */
+           wspace,         /* working space vector */
+           20);            /* number of elements (NOT size in bytes) */
+
+   Option bits for pcre2_dfa_match()
+
+       The  unused  bits of the options argument for pcre2_dfa_match() must be
+       zero.  The  only   bits   that   may   be   set   are   PCRE2_ANCHORED,
+       PCRE2_COPY_MATCHED_SUBJECT,  PCRE2_ENDANCHORED, PCRE2_NOTBOL, PCRE2_NO-
+       TEOL,   PCRE2_NOTEMPTY,   PCRE2_NOTEMPTY_ATSTART,   PCRE2_NO_UTF_CHECK,
+       PCRE2_PARTIAL_HARD,    PCRE2_PARTIAL_SOFT,    PCRE2_DFA_SHORTEST,   and
+       PCRE2_DFA_RESTART. All but the last four of these are exactly the  same
+       as for pcre2_match(), so their description is not repeated here.
+
+         PCRE2_PARTIAL_HARD
+         PCRE2_PARTIAL_SOFT
+
+       These  have  the  same general effect as they do for pcre2_match(), but
+       the details are slightly different. When PCRE2_PARTIAL_HARD is set  for
+       pcre2_dfa_match(),  it  returns  PCRE2_ERROR_PARTIAL  if the end of the
+       subject is reached and there is still at least one matching possibility
+       that requires additional characters. This happens even if some complete
+       matches have already been found. When PCRE2_PARTIAL_SOFT  is  set,  the
+       return  code  PCRE2_ERROR_NOMATCH is converted into PCRE2_ERROR_PARTIAL
+       if the end of the subject is  reached,  there  have  been  no  complete
+       matches, but there is still at least one matching possibility. The por-
+       tion  of  the  string that was inspected when the longest partial match
+       was found is set as the first matching string in both cases. There is a
+       more detailed discussion of partial and  multi-segment  matching,  with
+       examples, in the pcre2partial documentation.
+
+         PCRE2_DFA_SHORTEST
+
+       Setting  the PCRE2_DFA_SHORTEST option causes the matching algorithm to
+       stop as soon as it has found one match. Because of the way the alterna-
+       tive algorithm works, this is necessarily the shortest  possible  match
+       at the first possible matching point in the subject string.
+
+         PCRE2_DFA_RESTART
+
+       When  pcre2_dfa_match() returns a partial match, it is possible to call
+       it again, with additional subject characters, and have it continue with
+       the same match. The PCRE2_DFA_RESTART option requests this action; when
+       it is set, the workspace and wscount options must  reference  the  same
+       vector  as  before  because data about the match so far is left in them
+       after a partial match. There is more discussion of this facility in the
+       pcre2partial documentation.
+
+   Successful returns from pcre2_dfa_match()
+
+       When pcre2_dfa_match() succeeds, it may have matched more than one sub-
+       string in the subject. Note, however, that all the matches from one run
+       of the function start at the same point in  the  subject.  The  shorter
+       matches  are all initial substrings of the longer matches. For example,
+       if the pattern
+
+         <.*>
+
+       is matched against the string
+
+         This is    no more
+
+       the three matched strings are
+
+           
+          
+         
+
+       On success, the yield of the function is a number  greater  than  zero,
+       which  is  the  number  of  matched substrings. The offsets of the sub-
+       strings are returned in the ovector, and can be extracted by number  in
+       the  same way as for pcre2_match(), but the numbers bear no relation to
+       any capture groups that may exist in the pattern, because DFA  matching
+       does not support capturing.
+
+       Calls  to the convenience functions that extract substrings by name re-
+       turn the error PCRE2_ERROR_DFA_UFUNC (unsupported function) if used af-
+       ter a DFA match. The convenience functions that extract  substrings  by
+       number never return PCRE2_ERROR_NOSUBSTRING.
+
+       The  matched  strings  are  stored  in  the ovector in reverse order of
+       length; that is, the longest matching string is first.  If  there  were
+       too  many matches to fit into the ovector, the yield of the function is
+       zero, and the vector is filled with the longest matches.
+
+       NOTE: PCRE2's "auto-possessification" optimization usually  applies  to
+       character  repeats at the end of a pattern (as well as internally). For
+       example, the pattern "a\d+" is compiled as if it were "a\d++". For  DFA
+       matching,  this means that only one possible match is found. If you re-
+       ally do want multiple matches in such cases, either use an ungreedy re-
+       peat such as "a\d+?" or set the PCRE2_NO_AUTO_POSSESS option when  com-
+       piling.
+
+   Error returns from pcre2_dfa_match()
+
+       The pcre2_dfa_match() function returns a negative number when it fails.
+       Many  of  the  errors  are  the same as for pcre2_match(), as described
+       above.  There are in addition the following errors that are specific to
+       pcre2_dfa_match():
+
+         PCRE2_ERROR_DFA_UITEM
+
+       This return is given if pcre2_dfa_match() encounters  an  item  in  the
+       pattern  that it does not support, for instance, the use of \C in a UTF
+       mode or a backreference.
+
+         PCRE2_ERROR_DFA_UCOND
+
+       This return is given if pcre2_dfa_match() encounters a  condition  item
+       that uses a backreference for the condition, or a test for recursion in
+       a specific capture group. These are not supported.
+
+         PCRE2_ERROR_DFA_UINVALID_UTF
+
+       This  return is given if pcre2_dfa_match() is called for a pattern that
+       was compiled with PCRE2_MATCH_INVALID_UTF. This is  not  supported  for
+       DFA matching.
+
+         PCRE2_ERROR_DFA_WSSIZE
+
+       This  return  is  given  if  pcre2_dfa_match() runs out of space in the
+       workspace vector.
+
+         PCRE2_ERROR_DFA_RECURSE
+
+       When a recursion or subroutine call is processed, the matching function
+       calls itself recursively, using private  memory  for  the  ovector  and
+       workspace.   This  error  is given if the internal ovector is not large
+       enough. This should be extremely rare, as a  vector  of  size  1000  is
+       used.
+
+         PCRE2_ERROR_DFA_BADRESTART
+
+       When  pcre2_dfa_match()  is  called  with the PCRE2_DFA_RESTART option,
+       some plausibility checks are made on the  contents  of  the  workspace,
+       which  should  contain data about the previous partial match. If any of
+       these checks fail, this error is given.

+BUILDING PCRE2
+
+       PCRE2  is distributed with a configure script that can be used to build
+       the library in Unix-like environments using the applications  known  as
+       Autotools. Also in the distribution are files to support building using
+       CMake  instead  of configure. The text file README contains general in-
+       formation about building with Autotools (some of which is repeated  be-
+       low),  and  also  has some comments about building on various operating
+       systems. The files in the vms directory support building under OpenVMS.
+       There is a lot more information about building PCRE2 without using  Au-
+       totools  (including  information  about  using  CMake  and building "by
+       hand") in the text file called NON-AUTOTOOLS-BUILD.  You should consult
+       this file as well as the README file if you are building in a non-Unix-
+       like environment.
+
+
+PCRE2 BUILD-TIME OPTIONS
+
+       The rest of this document describes the optional features of PCRE2 that
+       can be selected when the library is compiled. It  assumes  use  of  the
+       configure  script,  where  the  optional features are selected or dese-
+       lected by providing options to configure before running the  make  com-
+       mand.  However,  the same options can be selected in both Unix-like and
+       non-Unix-like environments if you are using CMake instead of  configure
+       to build PCRE2.
+
+       If  you  are not using Autotools or CMake, option selection can be done
+       by editing the config.h file, or by passing parameter settings  to  the
+       compiler, as described in NON-AUTOTOOLS-BUILD.
+
+       The complete list of options for configure (which includes the standard
+       ones  such  as  the selection of the installation directory) can be ob-
+       tained by running
+
+         ./configure --help
+
+       The following sections include descriptions of "on/off"  options  whose
+       names begin with --enable or --disable. Because of the way that config-
+       ure  works, --enable and --disable always come in pairs, so the comple-
+       mentary option always exists as well, but as it specifies the  default,
+       it is not described.  Options that specify values have names that start
+       with --with. At the end of a configure run, a summary of the configura-
+       tion is output.
+
+
+BUILDING 8-BIT, 16-BIT AND 32-BIT LIBRARIES
+
+       By  default, a library called libpcre2-8 is built, containing functions
+       that take string arguments contained in arrays  of  bytes,  interpreted
+       either  as single-byte characters, or UTF-8 strings. You can also build
+       two other libraries, called libpcre2-16 and libpcre2-32, which  process
+       strings  that  are contained in arrays of 16-bit and 32-bit code units,
+       respectively. These can be interpreted either as single-unit characters
+       or UTF-16/UTF-32 strings. To build these additional libraries, add  one
+       or both of the following to the configure command:
+
+         --enable-pcre2-16
+         --enable-pcre2-32
+
+       If you do not want the 8-bit library, add
+
+         --disable-pcre2-8
+
+       as  well.  At least one of the three libraries must be built. Note that
+       the POSIX wrapper is for the 8-bit library only, and that pcre2grep  is
+       an  8-bit  program.  Neither  of these are built if you select only the
+       16-bit or 32-bit libraries.
+
+
+BUILDING SHARED AND STATIC LIBRARIES
+
+       The Autotools PCRE2 building process uses libtool to build both  shared
+       and  static  libraries by default. You can suppress an unwanted library
+       by adding one of
+
+         --disable-shared
+         --disable-static
+
+       to the configure command. Setting --disable-shared ensures  that  PCRE2
+       libraries  are  built  as  static libraries. The binaries that are then
+       created as part of  the  build  process  (for  example,  pcre2test  and
+       pcre2grep)  are linked statically with one or more PCRE2 libraries, but
+       may also be dynamically linked with other libraries such  as  libc.  If
+       you  want these binaries to be fully statically linked, you can set LD-
+       FLAGS like this:
+
+       LDFLAGS=--static ./configure --disable-shared
+
+       Note the two hyphens in --static. Of course, this works only if  static
+       versions of all the relevant libraries are available for linking.
+
+
+UNICODE AND UTF SUPPORT
+
+       By  default,  PCRE2 is built with support for Unicode and UTF character
+       strings.  To build it without Unicode support, add
+
+         --disable-unicode
+
+       to the configure command. This setting applies to all three  libraries.
+       It  is  not  possible to build one library with Unicode support and an-
+       other without in the same configuration.
+
+       Of itself, Unicode support does not make PCRE2 treat strings as  UTF-8,
+       UTF-16 or UTF-32. To do that, applications that use the library can set
+       the  PCRE2_UTF  option when they call pcre2_compile() to compile a pat-
+       tern.  Alternatively, patterns may be started with  (*UTF)  unless  the
+       application has locked this out by setting PCRE2_NEVER_UTF.
+
+       UTF support allows the libraries to process character code points up to
+       0x10ffff  in  the  strings that they handle. Unicode support also gives
+       access to the Unicode properties of characters, using  pattern  escapes
+       such as \P, \p, and \X. Only the general category properties such as Lu
+       and Nd, script names, and some bi-directional properties are supported.
+       Details are given in the pcre2pattern documentation.
+
+       Pattern escapes such as \d and \w do not by default make use of Unicode
+       properties.  The  application  can  request that they do by setting the
+       PCRE2_UCP option. Unless the application  has  set  PCRE2_NEVER_UCP,  a
+       pattern may also request this by starting with (*UCP).
+
+
+DISABLING THE USE OF \C
+
+       The \C escape sequence, which matches a single code unit, even in a UTF
+       mode,  can  cause unpredictable behaviour because it may leave the cur-
+       rent matching point in the middle of a multi-code-unit  character.  The
+       application  can lock it out by setting the PCRE2_NEVER_BACKSLASH_C op-
+       tion when calling pcre2_compile(). There is also a build-time option
+
+         --enable-never-backslash-C
+
+       (note the upper case C) which locks out the use of \C entirely.
+
+
+JUST-IN-TIME COMPILER SUPPORT
+
+       Just-in-time (JIT) compiler support is included in the build by  speci-
+       fying
+
+         --enable-jit
+
+       This  support  is available only for certain hardware architectures. If
+       this option is set for an unsupported architecture,  a  building  error
+       occurs.  If in doubt, use
+
+         --enable-jit=auto
+
+       which  enables  JIT  only if the current hardware is supported. You can
+       check if JIT is enabled in the configuration summary that is output  at
+       the  end  of a configure run. If you are enabling JIT under SELinux you
+       may also want to add
+
+         --enable-jit-sealloc
+
+       which enables the use of an execmem allocator in JIT that is compatible
+       with SELinux. This has no  effect  if  JIT  is  not  enabled.  See  the
+       pcre2jit  documentation for a discussion of JIT usage. When JIT support
+       is enabled, pcre2grep automatically makes use of it, unless you add
+
+         --disable-pcre2grep-jit
+
+       to the configure command.
+
+
+NEWLINE RECOGNITION
+
+       By default, PCRE2 interprets the linefeed (LF) character as  indicating
+       the  end  of  a line. This is the normal newline character on Unix-like
+       systems. You can compile PCRE2 to use carriage return (CR) instead,  by
+       adding
+
+         --enable-newline-is-cr
+
+       to  the  configure command. There is also an --enable-newline-is-lf op-
+       tion, which explicitly specifies linefeed as the newline character.
+
+       Alternatively, you can specify that line endings are to be indicated by
+       the two-character sequence CRLF (CR immediately followed by LF). If you
+       want this, add
+
+         --enable-newline-is-crlf
+
+       to the configure command. There is a fourth option, specified by
+
+         --enable-newline-is-anycrlf
+
+       which causes PCRE2 to recognize any of the three sequences CR,  LF,  or
+       CRLF as indicating a line ending. A fifth option, specified by
+
+         --enable-newline-is-any
+
+       causes  PCRE2  to  recognize  any Unicode newline sequence. The Unicode
+       newline sequences are the three just mentioned, plus the single charac-
+       ters VT (vertical tab, U+000B), FF (form feed, U+000C), NEL (next line,
+       U+0085), LS (line separator,  U+2028),  and  PS  (paragraph  separator,
+       U+2029). The final option is
+
+         --enable-newline-is-nul
+
+       which  causes  NUL  (binary  zero) to be set as the default line-ending
+       character.
+
+       Whatever default line ending convention is selected when PCRE2 is built
+       can be overridden by applications that use the library. At  build  time
+       it is recommended to use the standard for your operating system.
+
+
+WHAT \R MATCHES
+
+       By  default,  the  sequence \R in a pattern matches any Unicode newline
+       sequence, independently of what has been selected as  the  line  ending
+       sequence. If you specify
+
+         --enable-bsr-anycrlf
+
+       the  default  is changed so that \R matches only CR, LF, or CRLF. What-
+       ever is selected when PCRE2 is built can be overridden by  applications
+       that use the library.
+
+
+HANDLING VERY LARGE PATTERNS
+
+       Within  a  compiled  pattern,  offset values are used to point from one
+       part to another (for example, from an opening parenthesis to an  alter-
+       nation  metacharacter).  By default, in the 8-bit and 16-bit libraries,
+       two-byte values are used for these offsets, leading to a  maximum  size
+       for a compiled pattern of around 64 thousand code units. This is suffi-
+       cient  to handle all but the most gigantic patterns. Nevertheless, some
+       people do want to process truly enormous patterns, so it is possible to
+       compile PCRE2 to use three-byte or four-byte offsets by adding  a  set-
+       ting such as
+
+         --with-link-size=3
+
+       to  the  configure command. The value given must be 2, 3, or 4. For the
+       16-bit library, a value of 3 is rounded up to 4.  In  these  libraries,
+       using  longer  offsets slows down the operation of PCRE2 because it has
+       to load additional data when handling them. For the 32-bit library  the
+       value  is  always 4 and cannot be overridden; the value of --with-link-
+       size is ignored.
+
+
+LIMITING PCRE2 RESOURCE USAGE
+
+       The pcre2_match() function increments a counter each time it goes round
+       its main loop. Putting a limit on this counter controls the  amount  of
+       computing  resource  used  by a single call to pcre2_match(). The limit
+       can be changed at run time, as described in the pcre2api documentation.
+       The default is 10 million, but this can be changed by adding a  setting
+       such as
+
+         --with-match-limit=500000
+
+       to   the   configure   command.   This  setting  also  applies  to  the
+       pcre2_dfa_match() matching function, and to JIT  matching  (though  the
+       counting is done differently).
+
+       The  pcre2_match()  function  uses  heap  memory to record backtracking
+       points. The more nested backtracking points there  are  (that  is,  the
+       deeper  the  search tree), the more memory is needed. There is an upper
+       limit, specified in kibibytes (units of 1024 bytes). This limit can  be
+       changed  at  run  time, as described in the pcre2api documentation. The
+       default limit (in effect unlimited) is 20 million. You can change  this
+       by a setting such as
+
+         --with-heap-limit=500
+
+       which  limits the amount of heap to 500 KiB. This limit applies only to
+       interpretive matching in pcre2_match() and pcre2_dfa_match(), which may
+       also use the heap for internal workspace  when  processing  complicated
+       patterns.  This limit does not apply when JIT (which has its own memory
+       arrangements) is used.
+
+       You can also explicitly limit the depth of nested backtracking  in  the
+       pcre2_match() interpreter. This limit defaults to the value that is set
+       for  --with-match-limit.  You  can set a lower default limit by adding,
+       for example,
+
+         --with-match-limit-depth=10000
+
+       to the configure command. This value can be  overridden  at  run  time.
+       This  depth  limit  indirectly limits the amount of heap memory that is
+       used, but because the size of each backtracking "frame" depends on  the
+       number  of  capturing parentheses in a pattern, the amount of heap that
+       is used before the limit is reached varies  from  pattern  to  pattern.
+       This limit was more useful in versions before 10.30, where function re-
+       cursion was used for backtracking.
+
+       As well as applying to pcre2_match(), the depth limit also controls the
+       depth  of recursive function calls in pcre2_dfa_match(). These are used
+       for lookaround assertions, atomic groups,  and  recursion  within  pat-
+       terns.  The limit does not apply to JIT matching.
+
+
+LIMITING VARIABLE-LENGTH LOOKBEHIND ASSERTIONS
+
+       Lookbehind  assertions  in which one or more branches can match a vari-
+       able number of characters are supported only  if  there  is  a  maximum
+       matching  length  for  each  top-level branch. There is a limit to this
+       maximum that defaults to 255 characters. You can alter this default  by
+       a setting such as
+
+         --with-max-varlookbehind=100
+
+       The limit can be changed at runtime by calling pcre2_set_max_varlookbe-
+       hind().  Lookbehind  assertions  in  which every branch matches a fixed
+       number of characters (not necessarily all the same) are not constrained
+       by this limit.
+
+
+CREATING CHARACTER TABLES AT BUILD TIME
+
+       PCRE2 uses fixed tables for processing characters whose code points are
+       less than 256. By default, PCRE2 is built with a set of tables that are
+       distributed in the file src/pcre2_chartables.c.dist. These  tables  are
+       for ASCII codes only. If you add
+
+         --enable-rebuild-chartables
+
+       to  the  configure  command, the distributed tables are no longer used.
+       Instead, a program called pcre2_dftables is compiled and run. This out-
+       puts the source for new set of tables, created in the default locale of
+       your C run-time system. This method of replacing the  tables  does  not
+       work if you are cross compiling, because pcre2_dftables needs to be run
+       on the local host and therefore not compiled with the cross compiler.
+
+       If you need to create alternative tables when cross compiling, you will
+       have  to  do so "by hand". There may also be other reasons for creating
+       tables manually.  To cause pcre2_dftables to  be  built  on  the  local
+       host, run a normal compiling command, and then run the program with the
+       output file as its argument, for example:
+
+         cc src/pcre2_dftables.c -o pcre2_dftables
+         ./pcre2_dftables src/pcre2_chartables.c
+
+       This  builds the tables in the default locale of the local host. If you
+       want to specify a locale, you must use the -L option:
+
+         LC_ALL=fr_FR ./pcre2_dftables -L src/pcre2_chartables.c
+
+       You can also specify -b (with or without -L). This causes the tables to
+       be written in binary instead of as source code. A set of binary  tables
+       can  be  loaded  into memory by an application and passed to pcre2_com-
+       pile() in the same way as tables created by calling pcre2_maketables().
+       The tables are just a string of bytes, independent of hardware  charac-
+       teristics  such  as  endianness. This means they can be bundled with an
+       application that runs in different environments, to  ensure  consistent
+       behaviour.
+
+
+USING EBCDIC CODE
+
+       PCRE2  assumes  by default that it will run in an environment where the
+       character code is ASCII or Unicode, which is a superset of ASCII.  This
+       is the case for most computer operating systems. PCRE2 can, however, be
+       compiled to run in an 8-bit EBCDIC environment by adding
+
+         --enable-ebcdic --disable-unicode
+
+       to the configure command. This setting implies --enable-rebuild-charta-
+       bles.  You should only use it if you know that you are in an EBCDIC en-
+       vironment (for example, an IBM mainframe operating system).
+
+       It is not possible to support both EBCDIC and UTF-8 codes in  the  same
+       version  of  the  library. Consequently, --enable-unicode and --enable-
+       ebcdic are mutually exclusive.
+
+       The EBCDIC character that corresponds to an ASCII LF is assumed to have
+       the value 0x15 by default. However, in some EBCDIC  environments,  0x25
+       is used. In such an environment you should use
+
+         --enable-ebcdic-nl25
+
+       as well as, or instead of, --enable-ebcdic. The EBCDIC character for CR
+       has  the  same  value  as in ASCII, namely, 0x0d. Whichever of 0x15 and
+       0x25 is not chosen as LF is made to correspond to the Unicode NEL char-
+       acter (which, in Unicode, is 0x85).
+
+       The options that select newline behaviour, such as --enable-newline-is-
+       cr, and equivalent run-time options, refer to these character values in
+       an EBCDIC environment.
+
+
+PCRE2GREP SUPPORT FOR EXTERNAL SCRIPTS
+
+       By default pcre2grep supports the use of callouts with string arguments
+       within the patterns it is matching. There are two kinds: one that  gen-
+       erates output using local code, and another that calls an external pro-
+       gram  or  script.   If --disable-pcre2grep-callout-fork is added to the
+       configure command, only the first kind  of  callout  is  supported;  if
+       --disable-pcre2grep-callout  is  used,  all callouts are completely ig-
+       nored. For more details of pcre2grep callouts, see the pcre2grep  docu-
+       mentation.
+
+
+PCRE2GREP OPTIONS FOR COMPRESSED FILE SUPPORT
+
+       By  default,  pcre2grep reads all files as plain text. You can build it
+       so that it recognizes files whose names end in .gz or .bz2,  and  reads
+       them with libz or libbz2, respectively, by adding one or both of
+
+         --enable-pcre2grep-libz
+         --enable-pcre2grep-libbz2
+
+       to the configure command. These options naturally require that the rel-
+       evant  libraries  are installed on your system. Configuration will fail
+       if they are not.
+
+
+PCRE2GREP BUFFER SIZE
+
+       pcre2grep uses an internal buffer to hold a "window" on the file it  is
+       scanning, in order to be able to output "before" and "after" lines when
+       it finds a match. The default starting size of the buffer is 20KiB. The
+       buffer  itself  is  three times this size, but because of the way it is
+       used for holding "before" lines, the longest line that is guaranteed to
+       be processable is the notional buffer size. If a longer line is encoun-
+       tered, pcre2grep automatically expands the buffer, up  to  a  specified
+       maximum  size, whose default is 1MiB or the starting size, whichever is
+       the larger. You can change the default parameter values by adding,  for
+       example,
+
+         --with-pcre2grep-bufsize=51200
+         --with-pcre2grep-max-bufsize=2097152
+
+       to  the  configure  command. The caller of pcre2grep can override these
+       values by using --buffer-size  and  --max-buffer-size  on  the  command
+       line.
+
+
+PCRE2TEST OPTION FOR LIBREADLINE SUPPORT
+
+       If you add one of
+
+         --enable-pcre2test-libreadline
+         --enable-pcre2test-libedit
+
+       to  the configure command, pcre2test is linked with the libreadline or-
+       libedit library, respectively, and when its input is from  a  terminal,
+       it  reads  it using the readline() function. This provides line-editing
+       and history facilities. Note that libreadline is  GPL-licensed,  so  if
+       you  distribute  a binary of pcre2test linked in this way, there may be
+       licensing issues. These can be avoided by linking instead with libedit,
+       which has a BSD licence.
+
+       Setting --enable-pcre2test-libreadline causes the -lreadline option  to
+       be  added to the pcre2test build. In many operating environments with a
+       system-installed readline library this is sufficient. However, in  some
+       environments (e.g. if an unmodified distribution version of readline is
+       in  use),  some  extra configuration may be necessary. The INSTALL file
+       for libreadline says this:
+
+         "Readline uses the termcap functions, but does not link with
+         the termcap or curses library itself, allowing applications
+         which link with readline the to choose an appropriate library."
+
+       If your environment has not been set up so that an appropriate  library
+       is automatically included, you may need to add something like
+
+         LIBS="-ncurses"
+
+       immediately before the configure command.
+
+
+INCLUDING DEBUGGING CODE
+
+       If you add
+
+         --enable-debug
+
+       to  the configure command, additional debugging code is included in the
+       build. This feature is intended for use by the PCRE2 maintainers.
+
+
+DEBUGGING WITH VALGRIND SUPPORT
+
+       If you add
+
+         --enable-valgrind
+
+       to the configure command, PCRE2 will use valgrind annotations  to  mark
+       certain  memory  regions as unaddressable. This allows it to detect in-
+       valid memory accesses, and is mostly useful for debugging PCRE2 itself.
+
+
+CODE COVERAGE REPORTING
+
+       If your C compiler is gcc, you can build a version of  PCRE2  that  can
+       generate a code coverage report for its test suite. To enable this, you
+       must install lcov version 1.6 or above. Then specify
+
+         --enable-coverage
+
+       to the configure command and build PCRE2 in the usual way.
+
+       Note that using ccache (a caching C compiler) is incompatible with code
+       coverage  reporting. If you have configured ccache to run automatically
+       on your system, you must set the environment variable
+
+         CCACHE_DISABLE=1
+
+       before running make to build PCRE2, so that ccache is not used.
+
+       When --enable-coverage is used,  the  following  addition  targets  are
+       added to the Makefile:
+
+         make coverage
+
+       This  creates  a  fresh coverage report for the PCRE2 test suite. It is
+       equivalent to running "make coverage-reset", "make  coverage-baseline",
+       "make check", and then "make coverage-report".
+
+         make coverage-reset
+
+       This zeroes the coverage counters, but does nothing else.
+
+         make coverage-baseline
+
+       This captures baseline coverage information.
+
+         make coverage-report
+
+       This creates the coverage report.
+
+         make coverage-clean-report
+
+       This  removes the generated coverage report without cleaning the cover-
+       age data itself.
+
+         make coverage-clean-data
+
+       This removes the captured coverage data without removing  the  coverage
+       files created at compile time (*.gcno).
+
+         make coverage-clean
+
+       This  cleans all coverage data including the generated coverage report.
+       For more information about code coverage, see the gcov and  lcov  docu-
+       mentation.
+
+
+DISABLING THE Z AND T FORMATTING MODIFIERS
+
+       The  C99  standard  defines formatting modifiers z and t for size_t and
+       ptrdiff_t values, respectively. By default, PCRE2 uses these  modifiers
+       in environments other than old versions of Microsoft Visual Studio when
+       __STDC_VERSION__  is  defined  and has a value greater than or equal to
+       199901L (indicating support for C99).  However, there is at  least  one
+       environment that claims to be C99 but does not support these modifiers.
+       If
+
+         --disable-percent-zt
+
+       is specified, no use is made of the z or t modifiers. Instead of %td or
+       %zu,  a  suitable  format is used depending in the size of long for the
+       platform.
+
+
+SUPPORT FOR FUZZERS
+
+       There is a special option for use by people who  want  to  run  fuzzing
+       tests on PCRE2:
+
+         --enable-fuzz-support
+
+       At present this applies only to the 8-bit library. If set, it causes an
+       extra  library  called  libpcre2-fuzzsupport.a to be built, but not in-
+       stalled. This contains a single  function  called  LLVMFuzzerTestOneIn-
+       put()  whose  arguments are a pointer to a string and the length of the
+       string. When called, this function tries to compile  the  string  as  a
+       pattern,  and if that succeeds, to match it.  This is done both with no
+       options and with some random options bits that are generated  from  the
+       string.
+
+       Setting  --enable-fuzz-support  also  causes  a binary called pcre2fuz-
+       zcheck to be created. This is normally run under valgrind or used  when
+       PCRE2 is compiled with address sanitizing enabled. It calls the fuzzing
+       function  and  outputs  information  about  what it is doing. The input
+       strings are specified by arguments: if an argument starts with "="  the
+       rest  of it is a literal input string. Otherwise, it is assumed to be a
+       file name, and the contents of the file are the test string.
+
+
+OBSOLETE OPTION
+
+       In versions of PCRE2 prior to 10.30, there were two  ways  of  handling
+       backtracking  in the pcre2_match() function. The default was to use the
+       system stack, but if
+
+         --disable-stack-for-recursion
+
+       was set, memory on the heap was used. From release 10.30  onwards  this
+       has  changed  (the  stack  is  no longer used) and this option now does
+       nothing except give a warning.

+DESCRIPTION
+
+       PCRE2  provides  a  feature  called "callout", which is a means of tem-
+       porarily passing control to the caller of PCRE2 in the middle  of  pat-
+       tern  matching.  The  caller  of PCRE2 provides an external function by
+       putting its entry point in a match context (see pcre2_set_callout()  in
+       the pcre2api documentation).
+
+       When  using the pcre2_substitute() function, an additional callout fea-
+       ture is available. This does a callout after each change to the subject
+       string and is described in the pcre2api documentation; the rest of this
+       document is concerned with callouts during pattern matching.
+
+       Within a regular expression, (?C) indicates a point at  which  the
+       external  function  is  to  be  called. Different callout points can be
+       identified by putting a number less than 256 after the  letter  C.  The
+       default  value is zero.  Alternatively, the argument may be a delimited
+       string. The starting delimiter must be one of ` ' " ^ % # $ {  and  the
+       ending delimiter is the same as the start, except for {, where the end-
+       ing  delimiter  is  }.  If  the  ending  delimiter is needed within the
+       string, it must be doubled. For example, this pattern has  two  callout
+       points:
+
+         (?C1)abc(?C"some ""arbitrary"" text")def
+
+       If the PCRE2_AUTO_CALLOUT option bit is set when a pattern is compiled,
+       PCRE2  automatically inserts callouts, all with number 255, before each
+       item in the pattern except for immediately before or after an  explicit
+       callout. For example, if PCRE2_AUTO_CALLOUT is used with the pattern
+
+         A(?C3)B
+
+       it is processed as if it were
+
+         (?C255)A(?C3)B(?C255)
+
+       Here is a more complicated example:
+
+         A(\d{2}|--)
+
+       With PCRE2_AUTO_CALLOUT, this pattern is processed as if it were
+
+         (?C255)A(?C255)((?C255)\d{2}(?C255)|(?C255)-(?C255)-(?C255))(?C255)
+
+       Notice  that  there  is a callout before and after each parenthesis and
+       alternation bar. If the pattern contains a conditional group whose con-
+       dition is an assertion, an automatic callout  is  inserted  immediately
+       before  the  condition. Such a callout may also be inserted explicitly,
+       for example:
+
+         (?(?C9)(?=a)ab|de)  (?(?C%text%)(?!=d)ab|de)
+
+       This applies only to assertion conditions (because they are  themselves
+       independent groups).
+
+       Callouts  can  be useful for tracking the progress of pattern matching.
+       The pcre2test program has a pattern qualifier (/auto_callout) that sets
+       automatic callouts.  When any callouts are  present,  the  output  from
+       pcre2test  indicates  how  the pattern is being matched. This is useful
+       information when you are trying to optimize the performance of  a  par-
+       ticular pattern.
+
+
+MISSING CALLOUTS
+
+       You  should  be  aware  that, because of optimizations in the way PCRE2
+       compiles and matches patterns, callouts sometimes do not happen exactly
+       as you might expect.
+
+   Auto-possessification
+
+       At compile time, PCRE2 "auto-possessifies" repeated items when it knows
+       that what follows cannot be part of the repeat. For example, a+[bc]  is
+       compiled  as if it were a++[bc]. The pcre2test output when this pattern
+       is compiled with PCRE2_ANCHORED and PCRE2_AUTO_CALLOUT and then applied
+       to the string "aaaa" is:
+
+         --->aaaa
+          +0 ^        a+
+          +2 ^   ^    [bc]
+         No match
+
+       This indicates that when matching [bc] fails, there is no  backtracking
+       into a+ (because it is being treated as a++) and therefore the callouts
+       that  would  be  taken for the backtracks do not occur. You can disable
+       the  auto-possessify  feature  by  passing   PCRE2_NO_AUTO_POSSESS   to
+       pcre2_compile(),  or  starting  the pattern with (*NO_AUTO_POSSESS). In
+       this case, the output changes to this:
+
+         --->aaaa
+          +0 ^        a+
+          +2 ^   ^    [bc]
+          +2 ^  ^     [bc]
+          +2 ^ ^      [bc]
+          +2 ^^       [bc]
+         No match
+
+       This time, when matching [bc] fails, the matcher backtracks into a+ and
+       tries again, repeatedly, until a+ itself fails.
+
+   Automatic .* anchoring
+
+       By default, an optimization is applied when .* is the first significant
+       item in a pattern. If PCRE2_DOTALL is set, so that the  dot  can  match
+       any  character,  the pattern is automatically anchored. If PCRE2_DOTALL
+       is not set, a match can start only after an internal newline or at  the
+       beginning of the subject, and pcre2_compile() remembers this. If a pat-
+       tern  has more than one top-level branch, automatic anchoring occurs if
+       all branches are anchorable.
+
+       This optimization is disabled, however, if .* is in an atomic group  or
+       if  there  is a backreference to the capture group in which it appears.
+       It is also disabled if the pattern contains (*PRUNE) or  (*SKIP).  How-
+       ever, the presence of callouts does not affect it.
+
+       For  example,  if  the pattern .*\d is compiled with PCRE2_AUTO_CALLOUT
+       and applied to the string "aa", the pcre2test output is:
+
+         --->aa
+          +0 ^      .*
+          +2 ^ ^    \d
+          +2 ^^     \d
+          +2 ^      \d
+         No match
+
+       This shows that all match attempts start at the beginning of  the  sub-
+       ject. In other words, the pattern is anchored. You can disable this op-
+       timization  by  passing  PCRE2_NO_DOTSTAR_ANCHOR to pcre2_compile(), or
+       starting the pattern with (*NO_DOTSTAR_ANCHOR). In this case, the  out-
+       put changes to:
+
+         --->aa
+          +0 ^      .*
+          +2 ^ ^    \d
+          +2 ^^     \d
+          +2 ^      \d
+          +0  ^     .*
+          +2  ^^    \d
+          +2  ^     \d
+         No match
+
+       This  shows more match attempts, starting at the second subject charac-
+       ter.  Another optimization, described in the next section,  means  that
+       there is no subsequent attempt to match with an empty subject.
+
+   Other optimizations
+
+       Other  optimizations  that  provide fast "no match" results also affect
+       callouts.  For example, if the pattern is
+
+         ab(?C4)cd
+
+       PCRE2 knows that any matching string must contain the  letter  "d".  If
+       the  subject  string  is  "abyz",  the  lack of "d" means that matching
+       doesn't ever start, and the callout is  never  reached.  However,  with
+       "abyd", though the result is still no match, the callout is obeyed.
+
+       For  most  patterns  PCRE2  also knows the minimum length of a matching
+       string, and will immediately give a "no match" return without  actually
+       running  a  match if the subject is not long enough, or, for unanchored
+       patterns, if it has been scanned far enough.
+
+       You can disable these optimizations by passing the PCRE2_NO_START_OPTI-
+       MIZE option  to  pcre2_compile(),  or  by  starting  the  pattern  with
+       (*NO_START_OPT).  This slows down the matching process, but does ensure
+       that callouts such as the example above are obeyed.
+
+
+THE CALLOUT INTERFACE
+
+       During matching, when PCRE2 reaches a callout  point,  if  an  external
+       function  is  provided in the match context, it is called. This applies
+       to both normal, DFA, and JIT matching. The first argument to the  call-
+       out function is a pointer to a pcre2_callout block. The second argument
+       is  the  void * callout data that was supplied when the callout was set
+       up by calling pcre2_set_callout() (see the pcre2api documentation). The
+       callout block structure contains the following fields, not  necessarily
+       in this order:
+
+         uint32_t      version;
+         uint32_t      callout_number;
+         uint32_t      capture_top;
+         uint32_t      capture_last;
+         uint32_t      callout_flags;
+         PCRE2_SIZE   *offset_vector;
+         PCRE2_SPTR    mark;
+         PCRE2_SPTR    subject;

+         PCRE2_SIZE    start_match;

+         PCRE2_SIZE    callout_string_length;
+         PCRE2_SPTR    callout_string;
+
+       The  version field contains the version number of the block format. The
+       current version is 2; the three callout string fields  were  added  for
+       version  1, and the callout_flags field for version 2. If you are writ-
+       ing an application that might use an  earlier  release  of  PCRE2,  you
+       should  check  the version number before accessing any of these fields.
+       The version number will increase in future if more  fields  are  added,
+       but the intention is never to remove any of the existing fields.
+
+   Fields for numerical callouts
+
+       For  a  numerical  callout,  callout_string is NULL, and callout_number
+       contains the number of the callout, in the range  0-255.  This  is  the
+       number  that  follows  (?C for callouts that part of the pattern; it is
+       255 for automatically generated callouts.
+
+   Fields for string callouts
+
+       For callouts with string arguments, callout_number is always zero,  and
+       callout_string  points  to the string that is contained within the com-
+       piled pattern. Its length is given by callout_string_length. Duplicated
+       ending delimiters that were present in the original pattern string have
+       been turned into single characters, but there is no other processing of
+       the callout string argument. An additional code unit containing  binary
+       zero  is  present  after the string, but is not included in the length.
+       The delimiter that was used to start the string is also  stored  within
+       the  pattern, immediately before the string itself. You can access this
+       delimiter as callout_string[-1] if you need it.
+
+       The callout_string_offset field is the code unit offset to the start of
+       the callout argument string within the original pattern string. This is
+       provided for the benefit of applications such as script languages  that
+       might need to report errors in the callout string within the pattern.
+
+   Fields for all callouts
+
+       The  remaining  fields in the callout block are the same for both kinds
+       of callout.
+
+       The offset_vector field is a pointer to a vector of  capturing  offsets
+       (the "ovector"). You may read the elements in this vector, but you must
+       not change any of them.
+
+       For  calls  to pcre2_match(), the offset_vector field is not (since re-
+       lease 10.30) a pointer to the actual ovector that  was  passed  to  the
+       matching  function in the match data block. Instead it points to an in-
+       ternal ovector of a size large enough to  hold  all  possible  captured
+       substrings in the pattern. Note that whenever a recursion or subroutine
+       call  within  a pattern completes, the capturing state is reset to what
+       it was before.
+
+       The capture_last field contains the number of the  most  recently  cap-
+       tured  substring,  and the capture_top field contains one more than the
+       number of the highest numbered captured substring so far.  If  no  sub-
+       strings  have yet been captured, the value of capture_last is 0 and the
+       value of capture_top is 1. The values of these  fields  do  not  always
+       differ   by   one;  for  example,  when  the  callout  in  the  pattern
+       ((a)(b))(?C2) is taken, capture_last is 1 but capture_top is 4.
+
+       The contents of ovector[2] to  ovector[*2-1]  can  be  in-
+       spected  in  order to extract substrings that have been matched so far,
+       in the same way as extracting substrings after a match  has  completed.
+       The  values in ovector[0] and ovector[1] are always PCRE2_UNSET because
+       the match is by definition not complete. Substrings that have not  been
+       captured  but whose numbers are less than capture_top also have both of
+       their ovector slots set to PCRE2_UNSET.
+
+       For DFA matching, the offset_vector field points to  the  ovector  that
+       was  passed  to the matching function in the match data block for call-
+       outs at the top level, but to an internal ovector during the processing
+       of pattern recursions, lookarounds, and atomic groups.  However,  these
+       ovectors  hold no useful information because pcre2_dfa_match() does not
+       support substring capturing. The value of capture_top is always  1  and
+       the value of capture_last is always 0 for DFA matching.
+
+       The subject and subject_length fields contain copies of the values that
+       were passed to the matching function.
+
+       The  start_match  field normally contains the offset within the subject
+       at which the current match attempt started. However, if the escape  se-
+       quence  \K  has  been encountered, this value is changed to reflect the
+       modified starting point. If the pattern is not  anchored,  the  callout
+       function may be called several times from the same point in the pattern
+       for different starting points in the subject.
+
+       The  current_position  field  contains the offset within the subject of
+       the current match pointer.
+
+       The pattern_position field contains the offset in the pattern string to
+       the next item to be matched.
+
+       The next_item_length field contains the length of the next item  to  be
+       processed  in the pattern string. When the callout is at the end of the
+       pattern, the length is zero.  When  the  callout  precedes  an  opening
+       parenthesis, the length includes meta characters that follow the paren-
+       thesis.  For  example,  in a callout before an assertion such as (?=ab)
+       the length is 3. For an alternation bar or a closing  parenthesis,  the
+       length  is  one,  unless a closing parenthesis is followed by a quanti-
+       fier, in which case its length is included. (This  changed  in  release
+       10.23.  In  earlier  releases, before an opening parenthesis the length
+       was that of the entire group, and before an alternation bar or a  clos-
+       ing parenthesis the length was zero.)
+
+       The  pattern_position  and next_item_length fields are intended to help
+       in distinguishing between different automatic callouts, which all  have
+       the  same  callout  number. However, they are set for all callouts, and
+       are used by pcre2test to show the next item to be matched when display-
+       ing callout information.
+
+       In callouts from pcre2_match() the mark field contains a pointer to the
+       zero-terminated name of the most recently passed (*MARK), (*PRUNE),  or
+       (*THEN)  item  in the match, or NULL if no such items have been passed.
+       Instances of (*PRUNE) or (*THEN) without a name  do  not  obliterate  a
+       previous (*MARK). In callouts from the DFA matching function this field
+       always contains NULL.
+
+       The   callout_flags   field   is   always   zero   in   callouts   from
+       pcre2_dfa_match() or when JIT is being used. When pcre2_match() without
+       JIT is used, the following bits may be set:
+
+         PCRE2_CALLOUT_STARTMATCH
+
+       This is set for the first callout after the start of matching for  each
+       new starting position in the subject.
+
+         PCRE2_CALLOUT_BACKTRACK
+
+       This  is  set if there has been a matching backtrack since the previous
+       callout, or since the start of matching if this is  the  first  callout
+       from a pcre2_match() run.
+
+       Both  bits  are  set when a backtrack has caused a "bumpalong" to a new
+       starting position in the subject. Output from pcre2test does not  indi-
+       cate  the  presence  of these bits unless the callout_extra modifier is
+       set.
+
+       The information in the callout_flags field is provided so that applica-
+       tions can track and tell their users how matching with backtracking  is
+       done.  This  can be useful when trying to optimize patterns, or just to
+       understand how PCRE2 works. There is no  support  in  pcre2_dfa_match()
+       because  there is no backtracking in DFA matching, and there is no sup-
+       port in JIT because JIT is all about maximimizing matching performance.
+       In both these cases the callout_flags field is always zero.
+
+
+RETURN VALUES FROM CALLOUTS
+
+       The external callout function returns an integer to PCRE2. If the value
+       is zero, matching proceeds as normal. If  the  value  is  greater  than
+       zero,  matching  fails  at  the current point, but the testing of other
+       matching possibilities goes ahead, just as if a lookahead assertion had
+       failed. If the value is less than zero, the match is abandoned, and the
+       matching function returns the negative value.
+
+       Negative values should normally be chosen from  the  set  of  PCRE2_ER-
+       ROR_xxx  values.  In  particular, PCRE2_ERROR_NOMATCH forces a standard
+       "no match" failure. The error number  PCRE2_ERROR_CALLOUT  is  reserved
+       for use by callout functions; it will never be used by PCRE2 itself.
+
+
+CALLOUT ENUMERATION
+
+       int pcre2_callout_enumerate(const pcre2_code *code,
+         int (*callback)(pcre2_callout_enumerate_block *, void *),
+         void *user_data);
+
+       A script language that supports the use of string arguments in callouts
+       might  like  to  scan  all the callouts in a pattern before running the
+       match. This can be done by calling pcre2_callout_enumerate(). The first
+       argument is a pointer to a compiled pattern, the  second  points  to  a
+       callback  function,  and the third is arbitrary user data. The callback
+       function is called for every callout in the pattern  in  the  order  in
+       which they appear. Its first argument is a pointer to a callout enumer-
+       ation  block,  and  its second argument is the user_data value that was
+       passed to pcre2_callout_enumerate(). The data block contains  the  fol-
+       lowing fields:
+
+         version                Block version number
+         pattern_position       Offset to next item in pattern
+         next_item_length       Length of next item in pattern
+         callout_number         Number for numbered callouts
+         callout_string_offset  Offset to string within pattern
+         callout_string_length  Length of callout string
+         callout_string         Points to callout string or is NULL
+
+       The  version  number is currently 0. It will increase if new fields are
+       ever added to the block. The remaining fields are  the  same  as  their
+       namesakes  in  the pcre2_callout block that is used for callouts during
+       matching, as described above.
+
+       Note that the value of pattern_position is  unique  for  each  callout.
+       However,  if  a callout occurs inside a group that is quantified with a
+       non-zero minimum or a fixed maximum, the group is replicated inside the
+       compiled pattern. For example, a pattern such as /(a){2}/  is  compiled
+       as  if it were /(a)(a)/. This means that the callout will be enumerated
+       more than once, but with the same value for  pattern_position  in  each
+       case.
+
+       The callback function should normally return zero. If it returns a non-
+       zero value, scanning the pattern stops, and that value is returned from
+       pcre2_callout_enumerate().

+
+
+DIFFERENCES BETWEEN PCRE2 AND PERL
+
+       This  document describes some of the known differences in the ways that
+       PCRE2 and Perl handle regular expressions.  The  differences  described
+       here  are  with  respect  to  Perl version 5.38.0, but as both Perl and
+       PCRE2 are continually changing, the information may at times be out  of
+       date.
+
+       1.  When  PCRE2_DOTALL  (equivalent to Perl's /s qualifier) is not set,
+       the behaviour of the '.' metacharacter differs from Perl. In PCRE2, '.'
+       matches the next character unless it is the  start  of  a  newline  se-
+       quence.  This  means  that, if the newline setting is CR, CRLF, or NUL,
+       '.' will match the code point LF (0x0A) in ASCII/Unicode  environments,
+       and  NL  (either  0x15 or 0x25) when using EBCDIC. In Perl, '.' appears
+       never to match LF, even when 0x0A is not a newline indicator.
+
+       2. PCRE2 has only a subset of Perl's Unicode support. Details  of  what
+       it does have are given in the pcre2unicode page.
+
+       3.  Like  Perl, PCRE2 allows repeat quantifiers on parenthesized asser-
+       tions, but they do not mean what you might think. For example, (?!a){3}
+       does not assert that the next three characters are not "a". It just as-
+       serts that the next character is not "a"  three  times  (in  principle;
+       PCRE2  optimizes this to run the assertion just once). Perl allows some
+       repeat quantifiers on other assertions, for example, \b* , but these do
+       not seem to have any use. PCRE2 does not allow any kind  of  quantifier
+       on non-lookaround assertions.
+
+       4.  If a braced quantifier such as {1,2} appears where there is nothing
+       to repeat (for example, at the start of a branch), PCRE2 raises an  er-
+       ror whereas Perl treats the quantifier characters as literal.
+
+       5.  Capture groups that occur inside negative lookaround assertions are
+       counted, but their entries in the offsets vector are set  only  when  a
+       negative  assertion is a condition that has a matching branch (that is,
+       the condition is false).  Perl may set such  capture  groups  in  other
+       circumstances.
+
+       6.  The  following Perl escape sequences are not supported: \F, \l, \L,
+       \u, \U, and \N when followed by a character name. \N on its own, match-
+       ing a non-newline character, and \N{U+dd..}, matching  a  Unicode  code
+       point,  are  supported.  The  escapes that modify the case of following
+       letters are implemented by Perl's general string-handling and  are  not
+       part of its pattern matching engine. If any of these are encountered by
+       PCRE2,  an  error  is  generated  by default. However, if either of the
+       PCRE2_ALT_BSUX or PCRE2_EXTRA_ALT_BSUX options is set, \U  and  \u  are
+       interpreted as ECMAScript interprets them.
+
+       7. The Perl escape sequences \p, \P, and \X are supported only if PCRE2
+       is built with Unicode support (the default). The properties that can be
+       tested  with  \p  and \P are limited to the general category properties
+       such as Lu and Nd, the derived properties  Any  and  LC  (synonym  L&),
+       script  names such as Greek or Han, Bidi_Class, Bidi_Control, and a few
+       binary properties. Both PCRE2 and Perl support the Cs (surrogate) prop-
+       erty, but in PCRE2 its use is limited. See the pcre2pattern  documenta-
+       tion  for  details. The long synonyms for property names that Perl sup-
+       ports (such as \p{Letter}) are not supported by PCRE2, nor is  it  per-
+       mitted to prefix any of these properties with "Is".
+
+       8. PCRE2 supports the \Q...\E escape for quoting substrings. Characters
+       in between are treated as literals. However, this is slightly different
+       from  Perl  in  that  $  and  @ are also handled as literals inside the
+       quotes. In Perl, they cause variable interpolation (PCRE2 does not have
+       variables). Also, Perl does "double-quotish backslash interpolation" on
+       any backslashes between \Q and \E which, its documentation  says,  "may
+       lead  to confusing results". PCRE2 treats a backslash between \Q and \E
+       just like any other character. Note the following examples:
+
+           Pattern            PCRE2 matches     Perl matches
+
+           \Qabc$xyz\E        abc$xyz           abc followed by the
+                                                  contents of $xyz
+           \Qabc\$xyz\E       abc\$xyz          abc\$xyz
+           \Qabc\E\$\Qxyz\E   abc$xyz           abc$xyz
+           \QA\B\E            A\B               A\B
+           \Q\\E              \                 \\E
+
+       The \Q...\E sequence is recognized both inside  and  outside  character
+       classes by both PCRE2 and Perl.
+
+       9.   Fairly  obviously,  PCRE2  does  not  support  the  (?{code})  and
+       (??{code}) constructions. However, PCRE2 does have a "callout" feature,
+       which allows an external function to be called during pattern matching.
+       See the pcre2callout documentation for details.
+
+       10. Subroutine calls (whether recursive or not) were treated as  atomic
+       groups  up to PCRE2 release 10.23, but from release 10.30 this changed,
+       and backtracking into subroutine calls is now supported, as in Perl.
+
+       11. In PCRE2, if any of the backtracking control verbs are  used  in  a
+       group  that  is  called  as  a subroutine (whether or not recursively),
+       their effect is confined to that group; it does not extend to the  sur-
+       rounding  pattern.  This is not always the case in Perl. In particular,
+       if (*THEN) is present in a group that is called as  a  subroutine,  its
+       action is limited to that group, even if the group does not contain any
+       |  characters.  Note  that such groups are processed as anchored at the
+       point where they are tested.
+
+       12. If a pattern contains more than one backtracking control verb,  the
+       first  one  that  is backtracked onto acts. For example, in the pattern
+       A(*COMMIT)B(*PRUNE)C a failure in B triggers (*COMMIT), but  a  failure
+       in C triggers (*PRUNE). Perl's behaviour is more complex; in many cases
+       it is the same as PCRE2, but there are cases where it differs.
+
+       13.  There are some differences that are concerned with the settings of
+       captured strings when part of  a  pattern  is  repeated.  For  example,
+       matching  "aba"  against the pattern /^(a(b)?)+$/ in Perl leaves $2 un-
+       set, but in PCRE2 it is set to "b".
+
+       14. PCRE2's handling of duplicate capture group numbers  and  names  is
+       not  as  general as Perl's. This is a consequence of the fact the PCRE2
+       works internally just with numbers, using an external table  to  trans-
+       late  between  numbers  and  names.  In  particular,  a pattern such as
+       (?|(?A)|(?B)), where the two capture groups have the same  number
+       but  different  names, is not supported, and causes an error at compile
+       time. If it were allowed, it would not be possible to distinguish which
+       group matched, because both names map to capture  group  number  1.  To
+       avoid this confusing situation, an error is given at compile time.
+
+       15. Perl used to recognize comments in some places that PCRE2 does not,
+       for  example,  between  the  ( and ? at the start of a group. If the /x
+       modifier is set, Perl allowed white space between ( and  ?  though  the
+       latest  Perls give an error (for a while it was just deprecated). There
+       may still be some cases where Perl behaves differently.
+
+       16. Perl, when in warning mode, gives warnings  for  character  classes
+       such  as  [A-\d] or [a-[:digit:]]. It then treats the hyphens as liter-
+       als. PCRE2 has no warning features, so it gives an error in these cases
+       because they are almost certainly user mistakes.
+
+       17. In PCRE2, the upper/lower case character properties Lu and  Ll  are
+       not  affected when case-independent matching is specified. For example,
+       \p{Lu} always matches an upper case letter. I think Perl has changed in
+       this respect; in the release at the time of writing (5.38), \p{Lu}  and
+       \p{Ll} match all letters, regardless of case, when case independence is
+       specified.
+
+       18. From release 5.32.0, Perl locks out the use of \K in lookaround as-
+       sertions.  From  release 10.38 PCRE2 does the same by default. However,
+       there is an option for re-enabling the previous  behaviour.  When  this
+       option  is  set,  \K is acted on when it occurs in positive assertions,
+       but is ignored in negative assertions.
+
+       19. PCRE2 provides some extensions to the Perl regular  expression  fa-
+       cilities.   Perl  5.10  included  new features that were not in earlier
+       versions of Perl, some of which (such as  named  parentheses)  were  in
+       PCRE2 for some time before. This list is with respect to Perl 5.38:
+
+       (a)  If PCRE2_DOLLAR_ENDONLY is set and PCRE2_MULTILINE is not set, the
+       $ meta-character matches only at the very end of the string.
+
+       (b) A backslash followed  by  a  letter  with  no  special  meaning  is
+       faulted. (Perl can be made to issue a warning.)
+
+       (c)  If PCRE2_UNGREEDY is set, the greediness of the repetition quanti-
+       fiers is inverted, that is, by default they are not greedy, but if fol-
+       lowed by a question mark they are.
+
+       (d) PCRE2_ANCHORED can be used at matching time to force a  pattern  to
+       be tried only at the first matching position in the subject string.
+
+       (e)     The     PCRE2_NOTBOL,    PCRE2_NOTEOL,    PCRE2_NOTEMPTY    and
+       PCRE2_NOTEMPTY_ATSTART options have no Perl equivalents.
+
+       (f) The \R escape sequence can be restricted to match only CR,  LF,  or
+       CRLF by the PCRE2_BSR_ANYCRLF option.
+
+       (g)  The  callout  facility is PCRE2-specific. Perl supports codeblocks
+       and variable interpolation, but not general hooks on every match.
+
+       (h) The partial matching facility is PCRE2-specific.
+
+       (i) The alternative matching function (pcre2_dfa_match() matches  in  a
+       different way and is not Perl-compatible.
+
+       (j)  PCRE2 recognizes some special sequences such as (*CR) or (*NO_JIT)
+       at the start of a pattern. These set overall  options  that  cannot  be
+       changed within the pattern.
+
+       (k)  PCRE2  supports non-atomic positive lookaround assertions. This is
+       an extension to the lookaround facilities. The default, Perl-compatible
+       lookarounds are atomic.
+
+       (l) There are three syntactical items in patterns that can refer  to  a
+       capturing  group  by  number: back references such as \g{2}, subroutine
+       calls such as (?3), and condition references such as  (?(4)...).  PCRE2
+       supports  relative  group numbers such as +2 and -4 in all three cases.
+       Perl supports both plus and minus for subroutine calls, but only  minus
+       for back references, and no relative numbering at all for conditions.
+
+       20. Perl has different limits than PCRE2. See the pcre2limit documenta-
+       tion for details. Perl went with 5.10 from recursion to iteration keep-
+       ing the intermediate matches on the heap, which is ~10% slower but does
+       not  fall into any stack-overflow limit. PCRE2 made a similar change at
+       release 10.30, and also has many build-time and  run-time  customizable
+       limits.
+
+       21.  Unlike  Perl,  PCRE2 doesn't have character set modifiers and spe-
+       cially no way to set characters by context just  like  Perl's  "/d".  A
+       regular expression using PCRE2_UTF and PCRE2_UCP will use similar rules
+       to  Perl's  "/u";  something closer to "/a" could be selected by adding
+       other PCRE2_EXTRA_ASCII* options on top.
+
+       22. Some recursive patterns that Perl diagnoses as infinite  recursions
+       can be handled by PCRE2, either by the interpreter or the JIT. An exam-
+       ple is /(?:|(?0)abcd)(?(R)|\z)/, which matches a sequence of any number
+       of repeated "abcd" substrings at the end of the subject.

+PCRE2 JUST-IN-TIME COMPILER SUPPORT
+
+       Just-in-time  compiling  is a heavyweight optimization that can greatly
+       speed up pattern matching. However, it comes at the cost of extra  pro-
+       cessing  before  the  match is performed, so it is of most benefit when
+       the same pattern is going to be matched many times. This does not  nec-
+       essarily  mean many calls of a matching function; if the pattern is not
+       anchored, matching attempts may take place many times at various  posi-
+       tions in the subject, even for a single call. Therefore, if the subject
+       string  is  very  long,  it  may  still pay to use JIT even for one-off
+       matches. JIT support is available for all  of  the  8-bit,  16-bit  and
+       32-bit PCRE2 libraries.
+
+       JIT  support  applies  only to the traditional Perl-compatible matching
+       function.  It does not apply when the DFA matching  function  is  being
+       used. The code for JIT support was written by Zoltan Herczeg.
+
+
+AVAILABILITY OF JIT SUPPORT
+
+       JIT  support  is  an  optional feature of PCRE2. The "configure" option
+       --enable-jit (or equivalent CMake option) must be  set  when  PCRE2  is
+       built  if  you want to use JIT. The support is limited to the following
+       hardware platforms:
+
+         ARM 32-bit (v7, and Thumb2)
+         ARM 64-bit
+         IBM s390x 64 bit
+         Intel x86 32-bit and 64-bit
+         LoongArch 64 bit
+         MIPS 32-bit and 64-bit
+         Power PC 32-bit and 64-bit
+         RISC-V 32-bit and 64-bit
+
+       If --enable-jit is set on an unsupported platform, compilation fails.
+
+       A client program can tell  if  JIT  support  is  available  by  calling
+       pcre2_config()  with  the PCRE2_CONFIG_JIT option. The result is one if
+       PCRE2 was built with JIT support, and zero otherwise.  However,  having
+       the  JIT code available does not guarantee that it will be used for any
+       particular match. One reason for this is that there are a number of op-
+       tions and pattern items that are not supported by JIT (see below).  An-
+       other  reason  is that in some environments JIT is unable to get memory
+       in which to build its compiled code. The only guarantee from pcre2_con-
+       fig() is that if it returns zero, JIT will definitely not be used.
+
+       A simple program does not need to check availability in  order  to  use
+       JIT  when  possible. The API is implemented in a way that falls back to
+       the interpretive code if JIT is not available or cannot be used  for  a
+       given  match.  For  programs  that  need the best possible performance,
+       there is a "fast path" API that is JIT-specific.
+
+
+SIMPLE USE OF JIT
+
+       To make use of the JIT support in the simplest way, all you have to  do
+       is  to  call pcre2_jit_compile() after successfully compiling a pattern
+       with pcre2_compile(). This function has two arguments: the first is the
+       compiled pattern pointer that was returned by pcre2_compile(), and  the
+       second  is  zero  or  more of the following option bits: PCRE2_JIT_COM-
+       PLETE, PCRE2_JIT_PARTIAL_HARD, or PCRE2_JIT_PARTIAL_SOFT.
+
+       If JIT support is not available, a  call  to  pcre2_jit_compile()  does
+       nothing  and returns PCRE2_ERROR_JIT_BADOPTION. Otherwise, the compiled
+       pattern is passed to the JIT compiler, which turns it into machine code
+       that executes much faster than the normal interpretive code, but yields
+       exactly the same results. The returned value  from  pcre2_jit_compile()
+       is zero on success, or a negative error code.
+
+       There  is  a limit to the size of pattern that JIT supports, imposed by
+       the size of machine stack that it uses. The exact rules are  not  docu-
+       mented because they may change at any time, in particular, when new op-
+       timizations  are  introduced.   If  a  pattern  is  too  big, a call to
+       pcre2_jit_compile() returns PCRE2_ERROR_NOMEMORY.
+
+       PCRE2_JIT_COMPLETE requests the JIT compiler to generate code for  com-
+       plete  matches. If you want to run partial matches using the PCRE2_PAR-
+       TIAL_HARD or PCRE2_PARTIAL_SOFT options of  pcre2_match(),  you  should
+       set  one  or  both  of  the  other  options  as  well as, or instead of
+       PCRE2_JIT_COMPLETE. The JIT compiler generates different optimized code
+       for each of the three modes (normal, soft partial, hard partial).  When
+       pcre2_match()  is  called,  the appropriate code is run if it is avail-
+       able. Otherwise, the pattern is matched using interpretive code.
+
+       You can call pcre2_jit_compile() multiple times for the  same  compiled
+       pattern.  It does nothing if it has previously compiled code for any of
+       the option bits. For example, you can call it once with  PCRE2_JIT_COM-
+       PLETE  and  (perhaps  later,  when  you find you need partial matching)
+       again with PCRE2_JIT_COMPLETE and PCRE2_JIT_PARTIAL_HARD. This time  it
+       will ignore PCRE2_JIT_COMPLETE and just compile code for partial match-
+       ing. If pcre2_jit_compile() is called with no option bits set, it imme-
+       diately returns zero. This is an alternative way of testing whether JIT
+       is available.
+
+       At  present,  it  is not possible to free JIT compiled code except when
+       the entire compiled pattern is freed by calling pcre2_code_free().
+
+       In some circumstances you may need to call additional functions.  These
+       are  described  in the section entitled "Controlling the JIT stack" be-
+       low.
+
+       There are some pcre2_match() options that are not supported by JIT, and
+       there are also some pattern items that JIT cannot handle.  Details  are
+       given  below.   In both cases, matching automatically falls back to the
+       interpretive code. If you want to know whether JIT  was  actually  used
+       for  a particular match, you should arrange for a JIT callback function
+       to be set up as described in the section entitled "Controlling the  JIT
+       stack"  below,  even  if  you  do  not need to supply a non-default JIT
+       stack. Such a callback function is called whenever JIT code is about to
+       be obeyed. If the match-time options are not right for  JIT  execution,
+       the callback function is not obeyed.
+
+       If  the  JIT  compiler finds an unsupported item, no JIT data is gener-
+       ated. You can find out if JIT compilation was successful for a compiled
+       pattern by calling pcre2_pattern_info() with the PCRE2_INFO_JITSIZE op-
+       tion. A non-zero result means that JIT compilation  was  successful.  A
+       result of 0 means that JIT support is not available, or the pattern was
+       not  processed by pcre2_jit_compile(), or the JIT compiler was not able
+       to handle the pattern. Successful JIT compilation  does  not,  however,
+       guarantee  the  use  of  JIT at match time because there are some match
+       time options that are not supported by JIT.
+
+
+MATCHING SUBJECTS CONTAINING INVALID UTF
+
+       When a pattern is compiled with the PCRE2_UTF option,  subject  strings
+       are  normally expected to be a valid sequence of UTF code units. By de-
+       fault, this is checked at the start of matching and an error is  gener-
+       ated  if  invalid UTF is detected. The PCRE2_NO_UTF_CHECK option can be
+       passed to pcre2_match() to skip the check (for improved performance) if
+       you are sure that a subject string is valid. If  this  option  is  used
+       with  an  invalid  string, the result is undefined. The calling program
+       may crash or loop or otherwise misbehave.
+
+       However, a way of running matches on strings that may  contain  invalid
+       UTF   sequences   is   available.   Calling  pcre2_compile()  with  the
+       PCRE2_MATCH_INVALID_UTF option has two effects:  it  tells  the  inter-
+       preter  in pcre2_match() to support invalid UTF, and, if pcre2_jit_com-
+       pile() is subsequently called, the compiled JIT code also supports  in-
+       valid  UTF.  Details of how this support works, in both the JIT and the
+       interpretive cases, is given in the pcre2unicode documentation.
+
+       There  is  also  an  obsolete  option  for  pcre2_jit_compile()  called
+       PCRE2_JIT_INVALID_UTF, which currently exists only for backward compat-
+       ibility.     It   is   superseded   by   the   pcre2_compile()   option
+       PCRE2_MATCH_INVALID_UTF and should no longer be used. It may be removed
+       in future.
+
+
+UNSUPPORTED OPTIONS AND PATTERN ITEMS
+
+       The pcre2_match() options that  are  supported  for  JIT  matching  are
+       PCRE2_COPY_MATCHED_SUBJECT, PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY,
+       PCRE2_NOTEMPTY_ATSTART,   PCRE2_NO_UTF_CHECK,  PCRE2_PARTIAL_HARD,  and
+       PCRE2_PARTIAL_SOFT. The PCRE2_ANCHORED  and  PCRE2_ENDANCHORED  options
+       are not supported at match time.
+
+       If  the  PCRE2_NO_JIT option is passed to pcre2_match() it disables the
+       use of JIT, forcing matching by the interpreter code.
+
+       The only unsupported pattern items are \C (match a  single  data  unit)
+       when  running in a UTF mode, and a callout immediately before an asser-
+       tion condition in a conditional group.
+
+
+RETURN VALUES FROM JIT MATCHING
+
+       When a pattern is matched using JIT, the return values are the same  as
+       those  given  by the interpretive pcre2_match() code, with the addition
+       of one new error code: PCRE2_ERROR_JIT_STACKLIMIT. This means that  the
+       memory  used  for  the JIT stack was insufficient. See "Controlling the
+       JIT stack" below for a discussion of JIT stack usage.
+
+       The error code PCRE2_ERROR_MATCHLIMIT is returned by the  JIT  code  if
+       searching  a  very large pattern tree goes on for too long, as it is in
+       the same circumstance when JIT is not used, but the details of  exactly
+       what is counted are not the same. The PCRE2_ERROR_DEPTHLIMIT error code
+       is never returned when JIT matching is used.
+
+
+CONTROLLING THE JIT STACK
+
+       When the compiled JIT code runs, it needs a block of memory to use as a
+       stack.   By  default, it uses 32KiB on the machine stack. However, some
+       large or complicated patterns need more than this. The error  PCRE2_ER-
+       ROR_JIT_STACKLIMIT is given when there is not enough stack. Three func-
+       tions are provided for managing blocks of memory for use as JIT stacks.
+       There  is further discussion about the use of JIT stacks in the section
+       entitled "JIT stack FAQ" below.
+
+       The pcre2_jit_stack_create() function creates a JIT  stack.  Its  argu-
+       ments  are  a starting size, a maximum size, and a general context (for
+       memory allocation functions, or NULL for standard  memory  allocation).
+       It returns a pointer to an opaque structure of type pcre2_jit_stack, or
+       NULL  if there is an error. The pcre2_jit_stack_free() function is used
+       to free a stack that is no longer needed. If its argument is NULL, this
+       function returns immediately, without doing anything. (For the  techni-
+       cally  minded: the address space is allocated by mmap or VirtualAlloc.)
+       A maximum stack size of 512KiB to 1MiB should be more than  enough  for
+       any pattern.
+
+       The  pcre2_jit_stack_assign()  function  specifies which stack JIT code
+       should use. Its arguments are as follows:
+
+         pcre2_match_context  *mcontext
+         pcre2_jit_callback    callback
+         void                 *data
+
+       The first argument is a pointer to a match context. When this is subse-
+       quently passed to a matching function, its information determines which
+       JIT stack is used. If this argument is NULL, the function returns imme-
+       diately, without doing anything. There are three cases for  the  values
+       of the other two options:
+
+         (1) If callback is NULL and data is NULL, an internal 32KiB block
+             on the machine stack is used. This is the default when a match
+             context is created.
+
+         (2) If callback is NULL and data is not NULL, data must be
+             a pointer to a valid JIT stack, the result of calling
+             pcre2_jit_stack_create().
+
+         (3) If callback is not NULL, it must point to a function that is
+             called with data as an argument at the start of matching, in
+             order to set up a JIT stack. If the return from the callback
+             function is NULL, the internal 32KiB stack is used; otherwise the
+             return value must be a valid JIT stack, the result of calling
+             pcre2_jit_stack_create().
+
+       A  callback function is obeyed whenever JIT code is about to be run; it
+       is not obeyed when pcre2_match() is called with options that are incom-
+       patible for JIT matching. A callback function can therefore be used  to
+       determine  whether  a match operation was executed by JIT or by the in-
+       terpreter.
+
+       You may safely use the same JIT stack for more than one pattern (either
+       by assigning directly or by callback), as  long  as  the  patterns  are
+       matched sequentially in the same thread. Currently, the only way to set
+       up  non-sequential matches in one thread is to use callouts: if a call-
+       out function starts another match, that match must use a different  JIT
+       stack to the one used for currently suspended match(es).
+
+       In  a multithread application, if you do not specify a JIT stack, or if
+       you assign or pass back NULL from a callback, that is thread-safe,  be-
+       cause  each thread has its own machine stack. However, if you assign or
+       pass back a non-NULL JIT stack, this must be a different stack for each
+       thread so that the application is thread-safe.
+
+       Strictly speaking, even more is allowed. You can assign the  same  non-
+       NULL  stack  to a match context that is used by any number of patterns,
+       as long as they are not used for matching by multiple  threads  at  the
+       same  time.  For  example, you could use the same stack in all compiled
+       patterns, with a global mutex in the callback to wait until  the  stack
+       is available for use. However, this is an inefficient solution, and not
+       recommended.
+
+       This  is a suggestion for how a multithreaded program that needs to set
+       up non-default JIT stacks might operate:
+
+         During thread initialization
+           thread_local_var = pcre2_jit_stack_create(...)
+
+         During thread exit
+           pcre2_jit_stack_free(thread_local_var)
+
+         Use a one-line callback function
+           return thread_local_var
+
+       All the functions described in this section do nothing if  JIT  is  not
+       available.
+
+
+JIT STACK FAQ
+
+       (1) Why do we need JIT stacks?
+
+       PCRE2 (and JIT) is a recursive, depth-first engine, so it needs a stack
+       where  the local data of the current node is pushed before checking its
+       child nodes.  Allocating real machine stack on some platforms is diffi-
+       cult. For example, the stack chain needs to be updated every time if we
+       extend the stack on PowerPC.  Although it  is  possible,  its  updating
+       time overhead decreases performance. So we do the recursion in memory.
+
+       (2) Why don't we simply allocate blocks of memory with malloc()?
+
+       Modern  operating  systems have a nice feature: they can reserve an ad-
+       dress space instead of allocating memory. We can safely allocate memory
+       pages inside this address space, so the stack could grow without moving
+       memory data (this is important because of pointers). Thus we can  allo-
+       cate  1MiB  address  space,  and use only a single memory page (usually
+       4KiB) if that is enough. However, we can still grow up to 1MiB  anytime
+       if needed.
+
+       (3) Who "owns" a JIT stack?
+
+       The owner of the stack is the user program, not the JIT studied pattern
+       or anything else. The user program must ensure that if a stack is being
+       used by pcre2_match(), (that is, it is assigned to a match context that
+       is  passed  to  the  pattern currently running), that stack must not be
+       used by any other threads (to avoid overwriting the same memory  area).
+       The best practice for multithreaded programs is to allocate a stack for
+       each thread, and return this stack through the JIT callback function.
+
+       (4) When should a JIT stack be freed?
+
+       You can free a JIT stack at any time, as long as it will not be used by
+       pcre2_match() again. When you assign the stack to a match context, only
+       a  pointer  is  set. There is no reference counting or any other magic.
+       You can free compiled patterns, contexts, and stacks in any order, any-
+       time.  Just do not call pcre2_match() with a match context pointing  to
+       an already freed stack, as that will cause SEGFAULT. (Also, do not free
+       a  stack  currently  used  by pcre2_match() in another thread). You can
+       also replace the stack in a context at any time when it is not in  use.
+       You should free the previous stack before assigning a replacement.
+
+       (5)  Should  I  allocate/free  a  stack every time before/after calling
+       pcre2_match()?
+
+       No, because this is too costly in  terms  of  resources.  However,  you
+       could  implement  some clever idea which release the stack if it is not
+       used in let's say two minutes. The JIT callback  can  help  to  achieve
+       this without keeping a list of patterns.
+
+       (6)  OK, the stack is for long term memory allocation. But what happens
+       if a pattern causes stack overflow with a stack of 1MiB? Is  that  1MiB
+       kept until the stack is freed?
+
+       Especially on embedded systems, it might be a good idea to release mem-
+       ory  sometimes  without  freeing the stack. There is no API for this at
+       the moment.  Probably a function call which returns with the  currently
+       allocated  memory for any stack and another which allows releasing mem-
+       ory (shrinking the stack) would be a good idea if someone needs this.
+
+       (7) This is too much of a headache. Isn't there any better solution for
+       JIT stack handling?
+
+       No, thanks to Windows. If POSIX threads were used everywhere, we  could
+       throw out this complicated API.
+
+
+FREEING JIT SPECULATIVE MEMORY
+
+       void pcre2_jit_free_unused_memory(pcre2_general_context *gcontext);
+
+       The JIT executable allocator does not free all memory when it is possi-
+       ble.  It  expects new allocations, and keeps some free memory around to
+       improve allocation speed. However, in low memory conditions,  it  might
+       be  better to free all possible memory. You can cause this to happen by
+       calling pcre2_jit_free_unused_memory(). Its argument is a general  con-
+       text, for custom memory management, or NULL for standard memory manage-
+       ment.
+
+
+EXAMPLE CODE
+
+       This  is  a  single-threaded example that specifies a JIT stack without
+       using a callback. A real program should include  error  checking  after
+       all the function calls.
+
+         int rc;
+         pcre2_code *re;
+         pcre2_match_data *match_data;
+         pcre2_match_context *mcontext;
+         pcre2_jit_stack *jit_stack;
+
+         re = pcre2_compile(pattern, PCRE2_ZERO_TERMINATED, 0,
+           &errornumber, &erroffset, NULL);
+         rc = pcre2_jit_compile(re, PCRE2_JIT_COMPLETE);
+         mcontext = pcre2_match_context_create(NULL);
+         jit_stack = pcre2_jit_stack_create(32*1024, 512*1024, NULL);
+         pcre2_jit_stack_assign(mcontext, NULL, jit_stack);
+         match_data = pcre2_match_data_create(re, 10);
+         rc = pcre2_match(re, subject, length, 0, 0, match_data, mcontext);
+         /* Process result */
+
+         pcre2_code_free(re);
+         pcre2_match_data_free(match_data);
+         pcre2_match_context_free(mcontext);
+         pcre2_jit_stack_free(jit_stack);
+
+
+JIT FAST PATH API
+
+       Because the API described above falls back to interpreted matching when
+       JIT  is  not  available, it is convenient for programs that are written
+       for  general  use  in  many  environments.  However,  calling  JIT  via
+       pcre2_match() does have a performance impact. Programs that are written
+       for  use  where  JIT  is known to be available, and which need the best
+       possible performance, can instead use a "fast path"  API  to  call  JIT
+       matching  directly instead of calling pcre2_match() (obviously only for
+       patterns that have been successfully processed by pcre2_jit_compile()).
+
+       The fast path function is called pcre2_jit_match(), and  it  takes  ex-
+       actly  the same arguments as pcre2_match(). However, the subject string
+       must be specified with a  length;  PCRE2_ZERO_TERMINATED  is  not  sup-
+       ported.  Unsupported  option  bits  (for  example,  PCRE2_ANCHORED  and
+       PCRE2_ENDANCHORED) are ignored, as is the PCRE2_NO_JIT option. The  re-
+       turn  values  are  also  the  same as for pcre2_match(), plus PCRE2_ER-
+       ROR_JIT_BADOPTION if a matching mode (partial or complete) is requested
+       that was not compiled.
+
+       When you call pcre2_match(), as well as testing for invalid options,  a
+       number of other sanity checks are performed on the arguments. For exam-
+       ple,  if the subject pointer is NULL but the length is non-zero, an im-
+       mediate error is given. Also, unless PCRE2_NO_UTF_CHECK is set,  a  UTF
+       subject string is tested for validity. In the interests of speed, these
+       checks  do  not  happen  on  the  JIT fast path. If invalid UTF data is
+       passed when PCRE2_MATCH_INVALID_UTF was not  set  for  pcre2_compile(),
+       the  result  is  undefined. The program may crash or loop or give wrong
+       results. In the absence  of  PCRE2_MATCH_INVALID_UTF  you  should  call
+       pcre2_jit_match()  in  UTF  mode  only  if  you are sure the subject is
+       valid.
+
+       Bypassing the sanity checks and the  pcre2_match()  wrapping  can  give
+       speedups of more than 10%.

+
+SIZE AND OTHER LIMITATIONS
+
+       There are some size limitations in PCRE2 but it is hoped that they will
+       never in practice be relevant.
+
+       The  maximum  size  of  a compiled pattern is approximately 64 thousand
+       code units for the 8-bit and 16-bit libraries if PCRE2 is compiled with
+       the default internal linkage size, which  is  2  bytes  for  these  li-
+       braries.  If  you  want  to  process regular expressions that are truly
+       enormous, you can compile PCRE2 with an internal linkage size of 3 or 4
+       (when building the 16-bit library, 3 is  rounded  up  to  4).  See  the
+       README file in the source distribution and the pcre2build documentation
+       for  details.  In  these cases the limit is substantially larger.  How-
+       ever, the speed of execution is slower. In the 32-bit library, the  in-
+       ternal linkage size is always 4.
+
+       The maximum length of a source pattern string is essentially unlimited;
+       it  is  the largest number a PCRE2_SIZE variable can hold. However, the
+       program that calls pcre2_compile() can specify a smaller limit.
+
+       The maximum length (in code units) of a subject string is one less than
+       the largest number a PCRE2_SIZE variable can hold. PCRE2_SIZE is an un-
+       signed integer type, usually defined as size_t. Its maximum value (that
+       is ~(PCRE2_SIZE)0) is reserved as a special indicator  for  zero-termi-
+       nated strings and unset offsets.
+
+       All values in repeating quantifiers must be less than 65536.
+
+       There are two different limits that apply to branches of lookbehind as-
+       sertions.   If every branch in such an assertion matches a fixed number
+       of characters, the maximum length of any branch is 65535 characters. If
+       any branch matches a variable number of characters,  then  the  maximum
+       matching  length  for every branch is limited. The default limit is set
+       at compile time, defaulting to 255, but can be changed by  the  calling
+       program.
+
+       There  is no limit to the number of parenthesized groups, but there can
+       be no more than 65535 capture groups, and there is a limit to the depth
+       of nesting of parenthesized subpatterns of all kinds. This  is  imposed
+       in  order to limit the amount of system stack used at compile time. The
+       default limit can be specified when PCRE2 is built; if not, the default
+       is set to  250.  An  application  can  change  this  limit  by  calling
+       pcre2_set_parens_nest_limit() to set the limit in a compile context.
+
+       The  maximum length of name for a named capture group is 32 code units,
+       and the maximum number of such groups is 10000.
+
+       The maximum length of a  name  in  a  (*MARK),  (*PRUNE),  (*SKIP),  or
+       (*THEN)  verb  is  255  code units for the 8-bit library and 65535 code
+       units for the 16-bit and 32-bit libraries.
+
+       The maximum length of a string argument to a  callout  is  the  largest
+       number a 32-bit unsigned integer can hold.
+
+       The  maximum  amount  of heap memory used for matching is controlled by
+       the heap limit, which can be set in a pattern or in  a  match  context.
+       The default is a very large number, effectively unlimited.

+PCRE2 MATCHING ALGORITHMS
+
+       This document describes the two different algorithms that are available
+       in  PCRE2  for  matching  a compiled regular expression against a given
+       subject string. The "standard" algorithm is the  one  provided  by  the
+       pcre2_match() function. This works in the same as Perl's matching func-
+       tion,  and  provide  a Perl-compatible matching operation. The just-in-
+       time (JIT) optimization that is described in the pcre2jit documentation
+       is compatible with this function.
+
+       An alternative algorithm is provided by the pcre2_dfa_match() function;
+       it operates in a different way, and is not Perl-compatible. This alter-
+       native has advantages and disadvantages compared with the standard  al-
+       gorithm, and these are described below.
+
+       When there is only one possible way in which a given subject string can
+       match  a pattern, the two algorithms give the same answer. A difference
+       arises, however, when there are multiple possibilities. For example, if
+       the pattern
+
+         ^<.*>
+
+       is matched against the string
+
+           
+
+       there are three possible answers. The standard algorithm finds only one
+       of them, whereas the alternative algorithm finds all three.
+
+
+REGULAR EXPRESSIONS AS TREES
+
+       The set of strings that are matched by a regular expression can be rep-
+       resented as a tree structure. An unlimited repetition  in  the  pattern
+       makes  the  tree of infinite size, but it is still a tree. Matching the
+       pattern to a given subject string (from a given starting point) can  be
+       thought  of  as  a  search of the tree.  There are two ways to search a
+       tree: depth-first and breadth-first, and these correspond  to  the  two
+       matching algorithms provided by PCRE2.
+
+
+THE STANDARD MATCHING ALGORITHM
+
+       In  the terminology of Jeffrey Friedl's book "Mastering Regular Expres-
+       sions", the standard algorithm is an "NFA  algorithm".  It  conducts  a
+       depth-first  search  of  the pattern tree. That is, it proceeds along a
+       single path through the tree, checking that the subject matches what is
+       required. When there is a mismatch, the algorithm  tries  any  alterna-
+       tives  at  the  current point, and if they all fail, it backs up to the
+       previous branch point in the  tree,  and  tries  the  next  alternative
+       branch  at  that  level.  This often involves backing up (moving to the
+       left) in the subject string as well.  The  order  in  which  repetition
+       branches  are  tried  is controlled by the greedy or ungreedy nature of
+       the quantifier.
+
+       If a leaf node is reached, a matching string has  been  found,  and  at
+       that  point the algorithm stops. Thus, if there is more than one possi-
+       ble match, this algorithm returns the first one that it finds.  Whether
+       this  is the shortest, the longest, or some intermediate length depends
+       on the way the alternations and the greedy or ungreedy repetition quan-
+       tifiers are specified in the pattern.
+
+       Because it ends up with a single path through the  tree,  it  is  rela-
+       tively  straightforward  for  this  algorithm to keep track of the sub-
+       strings that are matched by portions of  the  pattern  in  parentheses.
+       This provides support for capturing parentheses and backreferences.
+
+
+THE ALTERNATIVE MATCHING ALGORITHM
+
+       This  algorithm  conducts  a breadth-first search of the tree. Starting
+       from the first matching point in the  subject,  it  scans  the  subject
+       string from left to right, once, character by character, and as it does
+       this,  it remembers all the paths through the tree that represent valid
+       matches. In Friedl's terminology, this is a kind  of  "DFA  algorithm",
+       though  it is not implemented as a traditional finite state machine (it
+       keeps multiple states active simultaneously).
+
+       Although the general principle of this matching algorithm  is  that  it
+       scans  the subject string only once, without backtracking, there is one
+       exception: when a lookaround assertion is encountered,  the  characters
+       following  or  preceding the current point have to be independently in-
+       spected.
+
+       The scan continues until either the end of the subject is  reached,  or
+       there  are  no more unterminated paths. At this point, terminated paths
+       represent the different matching possibilities (if there are none,  the
+       match  has  failed).   Thus,  if there is more than one possible match,
+       this algorithm finds all of them,  and  in  particular,  it  finds  the
+       longest.  The  matches  are returned in the output vector in decreasing
+       order of length. There is an option to stop  the  algorithm  after  the
+       first match (which is necessarily the shortest) is found.
+
+       Note  that the size of vector needed to contain all the results depends
+       on the number of simultaneous matches, not on the number of parentheses
+       in the pattern. Using pcre2_match_data_create_from_pattern() to  create
+       the  match  data block is therefore not advisable when doing DFA match-
+       ing.
+
+       Note also that all the matches that are found start at the  same  point
+       in the subject. If the pattern
+
+         cat(er(pillar)?)?
+
+       is  matched  against the string "the caterpillar catchment", the result
+       is the three strings "caterpillar", "cater", and "cat"  that  start  at
+       the  fifth  character  of the subject. The algorithm does not automati-
+       cally move on to find matches that start at later positions.
+
+       PCRE2's "auto-possessification" optimization usually applies to charac-
+       ter repeats at the end of a pattern (as well as internally). For  exam-
+       ple, the pattern "a\d+" is compiled as if it were "a\d++" because there
+       is  no  point even considering the possibility of backtracking into the
+       repeated digits. For DFA matching, this means that  only  one  possible
+       match  is  found. If you really do want multiple matches in such cases,
+       either use an ungreedy repeat ("a\d+?") or set  the  PCRE2_NO_AUTO_POS-
+       SESS option when compiling.
+
+       There  are  a  number of features of PCRE2 regular expressions that are
+       not supported or behave differently in the alternative  matching  func-
+       tion. Those that are not supported cause an error if encountered.
+
+       1.  Because the algorithm finds all possible matches, the greedy or un-
+       greedy nature of repetition quantifiers is not relevant (though it  may
+       affect  auto-possessification,  as  just  described).  During matching,
+       greedy and ungreedy quantifiers are treated in exactly  the  same  way.
+       However, possessive quantifiers can make a difference when what follows
+       could  also  match  what  is  quantified, for example in a pattern like
+       this:
+
+         ^a++\w!
+
+       This pattern matches "aaab!" but not "aaa!", which would be matched  by
+       a  non-possessive quantifier. Similarly, if an atomic group is present,
+       it is matched as if it were a standalone pattern at the current  point,
+       and  the  longest match is then "locked in" for the rest of the overall
+       pattern.
+
+       2. When dealing with multiple paths through the tree simultaneously, it
+       is not straightforward to keep track of  captured  substrings  for  the
+       different  matching  possibilities,  and PCRE2's implementation of this
+       algorithm does not attempt to do this. This means that no captured sub-
+       strings are available.
+
+       3. Because no substrings are captured, backreferences within  the  pat-
+       tern are not supported.
+
+       4.  For  the same reason, conditional expressions that use a backrefer-
+       ence as the condition or test for a specific group  recursion  are  not
+       supported.
+
+       5. Again for the same reason, script runs are not supported.
+
+       6. Because many paths through the tree may be active, the \K escape se-
+       quence,  which  resets the start of the match when encountered (but may
+       be on some paths and not on others), is not supported.
+
+       7. Callouts are supported, but the value of the  capture_top  field  is
+       always 1, and the value of the capture_last field is always 0.
+
+       8.  The  \C  escape  sequence, which (in the standard algorithm) always
+       matches a single code unit, even in a UTF mode,  is  not  supported  in
+       these  modes,  because the alternative algorithm moves through the sub-
+       ject string one character (not code unit) at a  time,  for  all  active
+       paths through the tree.
+
+       9.  Except for (*FAIL), the backtracking control verbs such as (*PRUNE)
+       are not supported. (*FAIL) is supported, and  behaves  like  a  failing
+       negative assertion.
+
+       10.  The PCRE2_MATCH_INVALID_UTF option for pcre2_compile() is not sup-
+       ported by pcre2_dfa_match().
+
+
+ADVANTAGES OF THE ALTERNATIVE ALGORITHM
+
+       The main advantage of the alternative algorithm is  that  all  possible
+       matches (at a single point in the subject) are automatically found, and
+       in  particular, the longest match is found. To find more than one match
+       at the same point using the standard algorithm, you have to  do  kludgy
+       things with callouts.
+
+       Partial  matching  is  possible with this algorithm, though it has some
+       limitations. The pcre2partial documentation gives  details  of  partial
+       matching and discusses multi-segment matching.
+
+
+DISADVANTAGES OF THE ALTERNATIVE ALGORITHM
+
+       The alternative algorithm suffers from a number of disadvantages:
+
+       1.  It  is  substantially  slower  than the standard algorithm. This is
+       partly because it has to search for all possible matches, but  is  also
+       because it is less susceptible to optimization.
+
+       2.  Capturing  parentheses,  backreferences,  script runs, and matching
+       within invalid UTF string are not supported.
+
+       3. Although atomic groups are supported, their use does not provide the
+       performance advantage that it does for the standard algorithm.
+
+       4. JIT optimization is not supported.

+
+
+PARTIAL MATCHING IN PCRE2
+
+       In  normal use of PCRE2, if there is a match up to the end of a subject
+       string, but more characters are needed to  match  the  entire  pattern,
+       PCRE2_ERROR_NOMATCH  is  returned,  just  like any other failing match.
+       There are circumstances where it might be helpful to  distinguish  this
+       "partial match" case.
+
+       One  example  is  an application where the subject string is very long,
+       and not all available at once. The requirement here is to be able to do
+       the matching segment by segment, but special action is  needed  when  a
+       matched substring spans the boundary between two segments.
+
+       Another  example is checking a user input string as it is typed, to en-
+       sure that it conforms to a required format. Invalid characters  can  be
+       immediately diagnosed and rejected, giving instant feedback.
+
+       Partial  matching  is a PCRE2-specific feature; it is not Perl-compati-
+       ble. It is requested  by  setting  one  of  the  PCRE2_PARTIAL_HARD  or
+       PCRE2_PARTIAL_SOFT  options  when calling a matching function. The dif-
+       ference between the two options is whether or not a  partial  match  is
+       preferred  to  an alternative complete match, though the details differ
+       between the two types of matching function. If both  options  are  set,
+       PCRE2_PARTIAL_HARD takes precedence.
+
+       If  you  want to use partial matching with just-in-time optimized code,
+       as well as setting a partial match option for  the  matching  function,
+       you  must  also  call pcre2_jit_compile() with one or both of these op-
+       tions:
+
+         PCRE2_JIT_PARTIAL_HARD
+         PCRE2_JIT_PARTIAL_SOFT
+
+       PCRE2_JIT_COMPLETE should also be set if you are going to run  non-par-
+       tial  matches  on  the same pattern. Separate code is compiled for each
+       mode. If the appropriate JIT mode has not been  compiled,  interpretive
+       matching code is used.
+
+       Setting  a partial matching option disables two of PCRE2's standard op-
+       timization hints. PCRE2 remembers the last literal code unit in a  pat-
+       tern,  and  abandons  matching  immediately if it is not present in the
+       subject string.  This optimization cannot be used for a subject  string
+       that  might match only partially. PCRE2 also remembers a minimum length
+       of a matching string, and does not bother to run the matching  function
+       on  shorter  strings.  This  optimization  is also disabled for partial
+       matching.
+
+
+REQUIREMENTS FOR A PARTIAL MATCH
+
+       A possible partial match occurs during matching when  the  end  of  the
+       subject  string is reached successfully, but either more characters are
+       needed to complete the match, or the addition of more characters  might
+       change what is matched.
+
+       Example  1: if the pattern is /abc/ and the subject is "ab", more char-
+       acters are definitely needed to complete a match.  In  this  case  both
+       hard and soft matching options yield a partial match.
+
+       Example  2: if the pattern is /ab+/ and the subject is "ab", a complete
+       match can be found, but the addition of more  characters  might  change
+       what  is  matched. In this case, only PCRE2_PARTIAL_HARD returns a par-
+       tial match; PCRE2_PARTIAL_SOFT returns the complete match.
+
+       On reaching the end of the subject, when PCRE2_PARTIAL_HARD is set,  if
+       the next pattern item is \z, \Z, \b, \B, or $ there is always a partial
+       match.   Otherwise, for both options, the next pattern item must be one
+       that inspects a character, and at least one of the  following  must  be
+       true:
+
+       (1)  At  least  one  character has already been inspected. An inspected
+       character need not form part of the final  matched  string;  lookbehind
+       assertions  and the \K escape sequence provide ways of inspecting char-
+       acters before the start of a matched string.
+
+       (2) The pattern contains one or more lookbehind assertions. This condi-
+       tion exists in case there is a lookbehind that inspects characters  be-
+       fore the start of the match.
+
+       (3)  There  is a special case when the whole pattern can match an empty
+       string.  When the starting point is at the  end  of  the  subject,  the
+       empty  string  match is a possibility, and if PCRE2_PARTIAL_SOFT is set
+       and neither of the above conditions is true, it is  returned.  However,
+       because  adding  more  characters  might  result  in a non-empty match,
+       PCRE2_PARTIAL_HARD returns a partial match, which in  this  case  means
+       "there  is going to be a match at this point, but until some more char-
+       acters are added, we do not know if it will be an empty string or some-
+       thing longer".
+
+
+PARTIAL MATCHING USING pcre2_match()
+
+       When  a  partial  matching  option  is  set,  the  result  of   calling
+       pcre2_match() can be one of the following:
+
+       A successful match
+         A complete match has been found, starting and ending within this sub-
+         ject.
+
+       PCRE2_ERROR_NOMATCH
+         No match can start anywhere in this subject.
+
+       PCRE2_ERROR_PARTIAL
+         Adding  more  characters may result in a complete match that uses one
+         or more characters from the end of this subject.
+
+       When a partial match is returned, the first two elements in the ovector
+       point to the portion of the subject that was matched, but the values in
+       the rest of the ovector are undefined. The appearance of \K in the pat-
+       tern has no effect for a partial match. Consider this pattern:
+
+         /abc\K123/
+
+       If it is matched against "456abc123xyz" the result is a complete match,
+       and the ovector defines the matched string as "123", because \K  resets
+       the  "start  of  match" point. However, if a partial match is requested
+       and the subject string is "456abc12", a partial match is found for  the
+       string  "abc12",  because  all these characters are needed for a subse-
+       quent re-match with additional characters.
+
+       If there is more than one partial match, the first one that  was  found
+       provides the data that is returned. Consider this pattern:
+
+         /123\w+X|dogY/
+
+       If  this is matched against the subject string "abc123dog", both alter-
+       natives fail to match, but the end of the  subject  is  reached  during
+       matching,  so PCRE2_ERROR_PARTIAL is returned. The offsets are set to 3
+       and 9, identifying "123dog" as the first partial match. (In this  exam-
+       ple,  there are two partial matches, because "dog" on its own partially
+       matches the second alternative.)
+
+   How a partial match is processed by pcre2_match()
+
+       What happens when a partial match is identified depends on which of the
+       two partial matching options is set.
+
+       If PCRE2_PARTIAL_HARD is set, PCRE2_ERROR_PARTIAL is returned  as  soon
+       as  a partial match is found, without continuing to search for possible
+       complete matches. This option is "hard" because it prefers  an  earlier
+       partial match over a later complete match. For this reason, the assump-
+       tion  is  made  that  the end of the supplied subject string is not the
+       true end of the available data, which is why \z, \Z, \b, \B, and $  al-
+       ways give a partial match.
+
+       If  PCRE2_PARTIAL_SOFT  is  set,  the  partial match is remembered, but
+       matching continues as normal, and other alternatives in the pattern are
+       tried. If no complete match can be found,  PCRE2_ERROR_PARTIAL  is  re-
+       turned instead of PCRE2_ERROR_NOMATCH. This option is "soft" because it
+       prefers a complete match over a partial match. All the various matching
+       items  in a pattern behave as if the subject string is potentially com-
+       plete; \z, \Z, and $ match at the end of the subject,  as  normal,  and
+       for \b and \B the end of the subject is treated as a non-alphanumeric.
+
+       The  difference  between the two partial matching options can be illus-
+       trated by a pattern such as:
+
+         /dog(sbody)?/
+
+       This matches either "dog" or "dogsbody", greedily (that is, it  prefers
+       the  longer  string  if  possible). If it is matched against the string
+       "dog" with PCRE2_PARTIAL_SOFT, it yields a complete  match  for  "dog".
+       However,  if  PCRE2_PARTIAL_HARD is set, the result is PCRE2_ERROR_PAR-
+       TIAL. On the other hand, if the pattern is made ungreedy the result  is
+       different:
+
+         /dog(sbody)??/
+
+       In  this  case  the  result  is always a complete match because that is
+       found first, and matching never  continues  after  finding  a  complete
+       match. It might be easier to follow this explanation by thinking of the
+       two patterns like this:
+
+         /dog(sbody)?/    is the same as  /dogsbody|dog/
+         /dog(sbody)??/   is the same as  /dog|dogsbody/
+
+       The  second pattern will never match "dogsbody", because it will always
+       find the shorter match first.
+
+   Example of partial matching using pcre2test
+
+       The pcre2test data modifiers partial_hard (or ph) and partial_soft  (or
+       ps)  set  PCRE2_PARTIAL_HARD and PCRE2_PARTIAL_SOFT, respectively, when
+       calling pcre2_match(). Here is a run of pcre2test using a pattern  that
+       matches the whole subject in the form of a date:
+
+           re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+         data> 25dec3\=ph
+         Partial match: 23dec3
+         data> 3ju\=ph
+         Partial match: 3ju
+         data> 3juj\=ph
+         No match
+
+       This  example  gives  the  same  results for both hard and soft partial
+       matching options. Here is an example where there is a difference:
+
+           re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+         data> 25jun04\=ps
+          0: 25jun04
+          1: jun
+         data> 25jun04\=ph
+         Partial match: 25jun04
+
+       With  PCRE2_PARTIAL_SOFT,  the  subject  is  matched  completely.   For
+       PCRE2_PARTIAL_HARD, however, the subject is assumed not to be complete,
+       so there is only a partial match.
+
+
+MULTI-SEGMENT MATCHING WITH pcre2_match()
+
+       PCRE  was  not originally designed with multi-segment matching in mind.
+       However, over time, features (including  partial  matching)  that  make
+       multi-segment matching possible have been added. A very long string can
+       be  searched  segment  by  segment by calling pcre2_match() repeatedly,
+       with the aim of achieving the same results that would happen if the en-
+       tire string was available for searching all  the  time.  Normally,  the
+       strings  that  are  being  sought are much shorter than each individual
+       segment, and are in the middle of very long strings, so the pattern  is
+       normally not anchored.
+
+       Special  logic  must  be implemented to handle a matched substring that
+       spans a segment boundary. PCRE2_PARTIAL_HARD should be used, because it
+       returns a partial match at the end of a segment whenever there  is  the
+       possibility  of  changing  the  match  by  adding  more characters. The
+       PCRE2_NOTBOL option should also be set for all but the first segment.
+
+       When a partial match occurs, the next segment must be added to the cur-
+       rent subject and the match re-run, using the  startoffset  argument  of
+       pcre2_match()  to  begin  at the point where the partial match started.
+       For example:
+
+           re> /\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d/
+         data> ...the date is 23ja\=ph
+         Partial match: 23ja
+         data> ...the date is 23jan19 and on that day...\=offset=15
+          0: 23jan19
+          1: jan
+
+       Note the use of the offset modifier to start the new  match  where  the
+       partial match was found. In this example, the next segment was added to
+       the  one  in  which  the  partial  match  was  found.  This is the most
+       straightforward approach, typically using a memory buffer that is twice
+       the size of each segment. After a partial match, the first half of  the
+       buffer  is  discarded,  the  second  half  is moved to the start of the
+       buffer, and a new segment is added before repeating the match as in the
+       example above. After a no match, the entire buffer can be discarded.
+
+       If there are memory constraints, you may want to discard text that pre-
+       cedes a partial match before adding the  next  segment.  Unfortunately,
+       this  is  not  at  present straightforward. In cases such as the above,
+       where the pattern does not contain any lookbehinds, it is sufficient to
+       retain only the partially matched substring. However,  if  the  pattern
+       contains  a  lookbehind assertion, characters that precede the start of
+       the partial match may have been inspected during the matching  process.
+       When  pcre2test displays a partial match, it indicates these characters
+       with '<' if the allusedtext modifier is set:
+
+           re> "(?<=123)abc"
+         data> xx123ab\=ph,allusedtext
+         Partial match: 123ab
+                        <<<
+
+       However, the allusedtext modifier is not available  for  JIT  matching,
+       because  JIT  matching  does  not  record the first (or last) consulted
+       characters.  For this reason, this information is not available via the
+       API. It is therefore not possible in general to obtain the exact number
+       of characters that must be retained in order to get the right match re-
+       sult. If you cannot retain the  entire  segment,  you  must  find  some
+       heuristic way of choosing.
+
+       If  you know the approximate length of the matching substrings, you can
+       use that to decide how much text to retain. The only lookbehind  infor-
+       mation  that  is  currently  available via the API is the length of the
+       longest individual lookbehind in a pattern, but this can be  misleading
+       if  there  are  nested  lookbehinds.  The  value  returned  by  calling
+       pcre2_pattern_info() with the PCRE2_INFO_MAXLOOKBEHIND  option  is  the
+       maximum number of characters (not code units) that any individual look-
+       behind   moves   back   when   it  is  processed.  A  pattern  such  as
+       "(?<=(? /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+         data> 23ja\=dfa,ps
+         Partial match: 23ja
+         data> n05\=dfa,dfa_restart
+          0: n05
+
+       The first call has "23ja" as the subject, and requests  partial  match-
+       ing;  the  second  call  has  "n05"  as  the  subject for the continued
+       (restarted) match.  Notice that when the match is  complete,  only  the
+       last  part  is  shown;  PCRE2 does not retain the previously partially-
+       matched string. It is up to the calling program to do that if it  needs
+       to.  This  means  that, for an unanchored pattern, if a continued match
+       fails, it is not possible to try again at a  new  starting  point.  All
+       this facility is capable of doing is continuing with the previous match
+       attempt. For example, consider this pattern:
+
+         1234|3789
+
+       If  the  first  part of the subject is "ABC123", a partial match of the
+       first alternative is found at offset 3. There is no partial  match  for
+       the second alternative, because such a match does not start at the same
+       point  in  the  subject  string. Attempting to continue with the string
+       "7890" does not yield a match  because  only  those  alternatives  that
+       match  at one point in the subject are remembered. Depending on the ap-
+       plication, this may or may not be what you want.
+
+       If you do want to allow for starting again at the next  character,  one
+       way  of  doing it is to retain some or all of the segment and try a new
+       complete match, as described for pcre2_match() above. Another possibil-
+       ity is to work with two buffers. If a partial match at offset n in  the
+       first  buffer  is followed by "no match" when PCRE2_DFA_RESTART is used
+       on the second buffer, you can then try a new match starting  at  offset
+       n+1 in the first buffer.

+
+PCRE2 REGULAR EXPRESSION DETAILS
+
+       The  syntax and semantics of the regular expressions that are supported
+       by PCRE2 are described in detail below. There is a quick-reference syn-
+       tax summary in the pcre2syntax page. PCRE2 tries to match  Perl  syntax
+       and  semantics as closely as it can.  PCRE2 also supports some alterna-
+       tive regular expression syntax (which does not conflict with  the  Perl
+       syntax) in order to provide some compatibility with regular expressions
+       in Python, .NET, and Oniguruma.
+
+       Perl's  regular expressions are described in its own documentation, and
+       regular expressions in general are covered in a number of  books,  some
+       of which have copious examples. Jeffrey Friedl's "Mastering Regular Ex-
+       pressions",  published by O'Reilly, covers regular expressions in great
+       detail. This description of PCRE2's regular expressions is intended  as
+       reference material.
+
+       This  document  discusses the regular expression patterns that are sup-
+       ported by PCRE2 when its  main  matching  function,  pcre2_match(),  is
+       used.    PCRE2    also    has   an   alternative   matching   function,
+       pcre2_dfa_match(), which matches using a different  algorithm  that  is
+       not  Perl-compatible.  Some  of  the  features  discussed below are not
+       available when DFA matching is used. The advantages  and  disadvantages
+       of  the  alternative function, and how it differs from the normal func-
+       tion, are discussed in the pcre2matching page.
+
+
+SPECIAL START-OF-PATTERN ITEMS
+
+       A number of options that can be passed to pcre2_compile() can  also  be
+       set by special items at the start of a pattern. These are not Perl-com-
+       patible,  but  are provided to make these options accessible to pattern
+       writers who are not able to change the program that processes the  pat-
+       tern.  Any  number  of these items may appear, but they must all be to-
+       gether right at the start of the pattern string, and the  letters  must
+       be in upper case.
+
+   UTF support
+
+       In the 8-bit and 16-bit PCRE2 libraries, characters may be coded either
+       as single code units, or as multiple UTF-8 or UTF-16 code units. UTF-32
+       can  be  specified  for the 32-bit library, in which case it constrains
+       the character values to valid  Unicode  code  points.  To  process  UTF
+       strings,  PCRE2  must be built to include Unicode support (which is the
+       default). When using UTF strings you must  either  call  the  compiling
+       function  with  one or both of the PCRE2_UTF or PCRE2_MATCH_INVALID_UTF
+       options, or the pattern must start with the  special  sequence  (*UTF),
+       which  is  equivalent  to setting the relevant PCRE2_UTF. How setting a
+       UTF mode affects pattern matching is mentioned in several places below.
+       There is also a summary of features in the pcre2unicode page.
+
+       Some applications that allow their users to supply patterns may wish to
+       restrict  them  to  non-UTF  data  for   security   reasons.   If   the
+       PCRE2_NEVER_UTF  option is passed to pcre2_compile(), (*UTF) is not al-
+       lowed, and its appearance in a pattern causes an error.
+
+   Unicode property support
+
+       Another special sequence that may appear at the start of a  pattern  is
+       (*UCP).   This  has the same effect as setting the PCRE2_UCP option: it
+       causes sequences such as \d and \w to use Unicode properties to  deter-
+       mine character types, instead of recognizing only characters with codes
+       less than 256 via a lookup table. If also causes upper/lower casing op-
+       erations  to  use  Unicode  properties  for characters with code points
+       greater than 127, even when UTF is not set.  These  behaviours  can  be
+       changed  within  the pattern; see the section entitled "Internal Option
+       Setting" below.
+
+       Some applications that allow their users to supply patterns may wish to
+       restrict them for security reasons. If the  PCRE2_NEVER_UCP  option  is
+       passed to pcre2_compile(), (*UCP) is not allowed, and its appearance in
+       a pattern causes an error.
+
+   Locking out empty string matching
+
+       Starting a pattern with (*NOTEMPTY) or (*NOTEMPTY_ATSTART) has the same
+       effect  as  passing the PCRE2_NOTEMPTY or PCRE2_NOTEMPTY_ATSTART option
+       to whichever matching function is subsequently called to match the pat-
+       tern. These options lock out the matching of empty strings, either  en-
+       tirely, or only at the start of the subject.
+
+   Disabling auto-possessification
+
+       If  a pattern starts with (*NO_AUTO_POSSESS), it has the same effect as
+       setting the PCRE2_NO_AUTO_POSSESS option. This stops PCRE2 from  making
+       quantifiers  possessive  when  what  follows  cannot match the repeated
+       item. For example, by default a+b is treated as a++b. For more details,
+       see the pcre2api documentation.
+
+   Disabling start-up optimizations
+
+       If a pattern starts with (*NO_START_OPT), it has  the  same  effect  as
+       setting the PCRE2_NO_START_OPTIMIZE option. This disables several opti-
+       mizations  for  quickly  reaching "no match" results. For more details,
+       see the pcre2api documentation.
+
+   Disabling automatic anchoring
+
+       If a pattern starts with (*NO_DOTSTAR_ANCHOR), it has the  same  effect
+       as  setting the PCRE2_NO_DOTSTAR_ANCHOR option. This disables optimiza-
+       tions that apply to patterns whose top-level branches all start with .*
+       (match any number of arbitrary characters). For more details,  see  the
+       pcre2api documentation.
+
+   Disabling JIT compilation
+
+       If  a  pattern  that starts with (*NO_JIT) is successfully compiled, an
+       attempt by the application to apply the  JIT  optimization  by  calling
+       pcre2_jit_compile() is ignored.
+
+   Setting match resource limits
+
+       The pcre2_match() function contains a counter that is incremented every
+       time it goes round its main loop. The caller of pcre2_match() can set a
+       limit  on  this counter, which therefore limits the amount of computing
+       resource used for a match. The maximum depth of nested backtracking can
+       also be limited; this indirectly restricts the amount  of  heap  memory
+       that  is  used,  but there is also an explicit memory limit that can be
+       set.
+
+       These facilities are provided to catch runaway matches  that  are  pro-
+       voked  by patterns with huge matching trees. A common example is a pat-
+       tern with nested unlimited repeats applied to a long string  that  does
+       not  match. When one of these limits is reached, pcre2_match() gives an
+       error return. The limits can also be set by items at the start  of  the
+       pattern of the form
+
+         (*LIMIT_HEAP=d)
+         (*LIMIT_MATCH=d)
+         (*LIMIT_DEPTH=d)
+
+       where d is any number of decimal digits. However, the value of the set-
+       ting  must  be  less than the value set (or defaulted) by the caller of
+       pcre2_match() for it to have any effect. In other  words,  the  pattern
+       writer  can lower the limits set by the programmer, but not raise them.
+       If there is more than one setting of one of  these  limits,  the  lower
+       value  is used. The heap limit is specified in kibibytes (units of 1024
+       bytes).
+
+       Prior to release 10.30, LIMIT_DEPTH was  called  LIMIT_RECURSION.  This
+       name is still recognized for backwards compatibility.
+
+       The heap limit applies only when the pcre2_match() or pcre2_dfa_match()
+       interpreters are used for matching. It does not apply to JIT. The match
+       limit  is used (but in a different way) when JIT is being used, or when
+       pcre2_dfa_match() is called, to limit computing resource usage by those
+       matching functions. The depth limit is ignored by JIT but  is  relevant
+       for  DFA  matching, which uses function recursion for recursions within
+       the pattern and for lookaround assertions and atomic  groups.  In  this
+       case, the depth limit controls the depth of such recursion.
+
+   Newline conventions
+
+       PCRE2  supports six different conventions for indicating line breaks in
+       strings: a single CR (carriage return) character, a  single  LF  (line-
+       feed) character, the two-character sequence CRLF, any of the three pre-
+       ceding,  any  Unicode  newline  sequence,  or the NUL character (binary
+       zero). The pcre2api page has further  discussion  about  newlines,  and
+       shows how to set the newline convention when calling pcre2_compile().
+
+       It  is also possible to specify a newline convention by starting a pat-
+       tern string with one of the following sequences:
+
+         (*CR)        carriage return
+         (*LF)        linefeed
+         (*CRLF)      carriage return, followed by linefeed
+         (*ANYCRLF)   any of the three above
+         (*ANY)       all Unicode newline sequences
+         (*NUL)       the NUL character (binary zero)
+
+       These override the default and the options given to the compiling func-
+       tion. For example, on a Unix system where LF is the default newline se-
+       quence, the pattern
+
+         (*CR)a.b
+
+       changes the convention to CR. That pattern matches "a\nb" because LF is
+       no longer a newline. If more than one of these settings is present, the
+       last one is used.
+
+       The newline convention affects where the circumflex and  dollar  asser-
+       tions are true. It also affects the interpretation of the dot metachar-
+       acter  when  PCRE2_DOTALL  is not set, and the behaviour of \N when not
+       followed by an opening brace. However, it does not affect what  the  \R
+       escape  sequence  matches.  By default, this is any Unicode newline se-
+       quence, for Perl compatibility. However, this can be changed;  see  the
+       next section and the description of \R in the section entitled "Newline
+       sequences"  below. A change of \R setting can be combined with a change
+       of newline convention.
+
+   Specifying what \R matches
+
+       It is possible to restrict \R to match only CR, LF, or CRLF (instead of
+       the complete set  of  Unicode  line  endings)  by  setting  the  option
+       PCRE2_BSR_ANYCRLF  at compile time. This effect can also be achieved by
+       starting a pattern with (*BSR_ANYCRLF).  For  completeness,  (*BSR_UNI-
+       CODE) is also recognized, corresponding to PCRE2_BSR_UNICODE.
+
+
+EBCDIC CHARACTER CODES
+
+       PCRE2  can be compiled to run in an environment that uses EBCDIC as its
+       character code instead of ASCII or Unicode (typically a mainframe  sys-
+       tem).  In  the  sections below, character code values are ASCII or Uni-
+       code; in an EBCDIC environment these characters may have different code
+       values, and there are no code points greater than 255.
+
+
+CHARACTERS AND METACHARACTERS
+
+       A regular expression is a pattern that is  matched  against  a  subject
+       string  from  left  to right. Most characters stand for themselves in a
+       pattern, and match the corresponding characters in the  subject.  As  a
+       trivial example, the pattern
+
+         The quick brown fox
+
+       matches a portion of a subject string that is identical to itself. When
+       caseless  matching  is  specified  (the  PCRE2_CASELESS  option or (?i)
+       within the pattern), letters are matched independently  of  case.  Note
+       that  there  are  two  ASCII  characters, K and S, that, in addition to
+       their lower case ASCII equivalents, are  case-equivalent  with  Unicode
+       U+212A  (Kelvin  sign)  and  U+017F  (long  S) respectively when either
+       PCRE2_UTF or PCRE2_UCP is set, unless the PCRE2_EXTRA_CASELESS_RESTRICT
+       option is in force (either passed to pcre2_compile()  or  set  by  (?r)
+       within the pattern).
+
+       The power of regular expressions comes from the ability to include wild
+       cards, character classes, alternatives, and repetitions in the pattern.
+       These are encoded in the pattern by the use of metacharacters, which do
+       not  stand  for  themselves but instead are interpreted in some special
+       way.
+
+       There are two different sets of metacharacters: those that  are  recog-
+       nized  anywhere in the pattern except within square brackets, and those
+       that are recognized within square brackets.  Outside  square  brackets,
+       the metacharacters are as follows:
+
+         \      general escape character with several uses
+         ^      assert start of string (or line, in multiline mode)
+         $      assert end of string (or line, in multiline mode)
+         .      match any character except newline (by default)
+         [      start character class definition
+         |      start of alternative branch
+         (      start group or control verb
+         )      end group or control verb
+         *      0 or more quantifier
+         +      1 or more quantifier; also "possessive quantifier"
+         ?      0 or 1 quantifier; also quantifier minimizer
+         {      potential start of min/max quantifier
+
+       Brace  characters  {  and } are also used to enclose data for construc-
+       tions such as \g{2} or \k{name}. In almost all uses  of  braces,  space
+       and/or horizontal tab characters that follow { or precede } are allowed
+       and  are  ignored. In the case of quantifiers, they may also appear be-
+       fore or after the comma. The exception to this is \u{...} which  is  an
+       ECMAScript  compatibility  feature  that  is  recognized  only when the
+       PCRE2_EXTRA_ALT_BSUX option is set. ECMAScript  does  not  ignore  such
+       white space; it causes the item to be interpreted as literal.
+
+       Part  of  a  pattern  that is in square brackets is called a "character
+       class". In a character class the only metacharacters are:
+
+         \      general escape character
+         ^      negate the class, but only if the first character
+         -      indicates character range
+         [      POSIX character class (if followed by POSIX syntax)
+         ]      terminates the character class
+
+       If a pattern is compiled with the  PCRE2_EXTENDED  option,  most  white
+       space in the pattern, other than in a character class, within a \Q...\E
+       sequence,  or  between  a # outside a character class and the next new-
+       line, inclusive, are ignored. An escaping backslash can be used to  in-
+       clude  a  white  space  or a # character as part of the pattern. If the
+       PCRE2_EXTENDED_MORE option is set, the same applies,  but  in  addition
+       unescaped  space  and  horizontal  tab  characters are ignored inside a
+       character class. Note: only these two characters are ignored,  not  the
+       full  set  of pattern white space characters that are ignored outside a
+       character class. Option settings can be changed within a  pattern;  see
+       the section entitled "Internal Option Setting" below.
+
+       The following sections describe the use of each of the metacharacters.
+
+
+BACKSLASH
+
+       The backslash character has several uses. Firstly, if it is followed by
+       a  character that is not a digit or a letter, it takes away any special
+       meaning that character may have. This use of  backslash  as  an  escape
+       character applies both inside and outside character classes.
+
+       For  example,  if you want to match a * character, you must write \* in
+       the pattern. This escaping action applies whether or not the  following
+       character  would  otherwise be interpreted as a metacharacter, so it is
+       always safe to precede a non-alphanumeric  with  backslash  to  specify
+       that it stands for itself.  In particular, if you want to match a back-
+       slash, you write \\.
+
+       Only  ASCII  digits  and letters have any special meaning after a back-
+       slash. All other characters (in particular, those whose code points are
+       greater than 127) are treated as literals.
+
+       If you want to treat all characters in a sequence as literals, you  can
+       do  so by putting them between \Q and \E. Note that this includes white
+       space even when the PCRE2_EXTENDED option is set  so  that  most  other
+       white  space is ignored. The behaviour is different from Perl in that $
+       and @ are handled as literals in \Q...\E sequences in PCRE2, whereas in
+       Perl, $ and @ cause variable interpolation. Also,  Perl  does  "double-
+       quotish  backslash  interpolation" on any backslashes between \Q and \E
+       which, its documentation says, "may lead to confusing  results".  PCRE2
+       treats  a  backslash  between  \Q and \E just like any other character.
+       Note the following examples:
+
+         Pattern            PCRE2 matches   Perl matches
+
+         \Qabc$xyz\E        abc$xyz        abc followed by the
+                                             contents of $xyz
+         \Qabc\$xyz\E       abc\$xyz       abc\$xyz
+         \Qabc\E\$\Qxyz\E   abc$xyz        abc$xyz
+         \QA\B\E            A\B            A\B
+         \Q\\E              \              \\E
+
+       The \Q...\E sequence is recognized both inside  and  outside  character
+       classes.   An  isolated \E that is not preceded by \Q is ignored. If \Q
+       is not followed by \E later in the pattern, the literal  interpretation
+       continues  to  the  end  of  the pattern (that is, \E is assumed at the
+       end). If the isolated \Q is inside a character class,  this  causes  an
+       error,  because the character class is then not terminated by a closing
+       square bracket.
+
+   Non-printing characters
+
+       A second use of backslash provides a way of encoding non-printing char-
+       acters in patterns in a visible manner. There is no restriction on  the
+       appearance  of non-printing characters in a pattern, but when a pattern
+       is being prepared by text editing, it is often easier to use one of the
+       following escape sequences instead of the binary  character  it  repre-
+       sents.  In  an  ASCII or Unicode environment, these escapes are as fol-
+       lows:
+
+         \a          alarm, that is, the BEL character (hex 07)
+         \cx         "control-x", where x is a non-control ASCII character
+         \e          escape (hex 1B)
+         \f          form feed (hex 0C)
+         \n          linefeed (hex 0A)
+         \r          carriage return (hex 0D) (but see below)
+         \t          tab (hex 09)
+         \0dd        character with octal code 0dd
+         \ddd        character with octal code ddd, or backreference
+         \o{ddd..}   character with octal code ddd..
+         \xhh        character with hex code hh
+         \x{hhh..}   character with hex code hhh..
+         \N{U+hhh..} character with Unicode hex code point hhh..
+
+       By default, after \x that is not followed by {, from zero to two  hexa-
+       decimal  digits  are  read (letters can be in upper or lower case). Any
+       number of hexadecimal digits may appear between \x{ and }. If a charac-
+       ter other than a hexadecimal digit appears between \x{  and  },  or  if
+       there is no terminating }, an error occurs.
+
+       Characters whose code points are less than 256 can be defined by either
+       of the two syntaxes for \x or by an octal sequence. There is no differ-
+       ence in the way they are handled. For example, \xdc is exactly the same
+       as  \x{dc}  or \334.  However, using the braced versions does make such
+       sequences easier to read.
+
+       Support is available for some ECMAScript (aka  JavaScript)  escape  se-
+       quences via two compile-time options. If PCRE2_ALT_BSUX is set, the se-
+       quence  \x  followed  by { is not recognized. Only if \x is followed by
+       two hexadecimal digits is it recognized as a character  escape.  Other-
+       wise  it  is interpreted as a literal "x" character. In this mode, sup-
+       port for code points greater than 256 is provided by \u, which must  be
+       followed  by  four hexadecimal digits; otherwise it is interpreted as a
+       literal "u" character.
+
+       PCRE2_EXTRA_ALT_BSUX has the same effect as PCRE2_ALT_BSUX and, in  ad-
+       dition, \u{hhh..} is recognized as the character specified by hexadeci-
+       mal code point.  There may be any number of hexadecimal digits, but un-
+       like  other places that also use curly brackets, spaces are not allowed
+       and would result in the string being interpreted  as  a  literal.  This
+       syntax is from ECMAScript 6.
+
+       The  \N{U+hhh..} escape sequence is recognized only when PCRE2 is oper-
+       ating in UTF mode. Perl also uses \N{name}  to  specify  characters  by
+       Unicode  name;  PCRE2  does  not support this. Note that when \N is not
+       followed by an opening brace (curly bracket) it has an entirely differ-
+       ent meaning, matching any character that is not a newline.
+
+       There are some legacy applications where the escape sequence \r is  ex-
+       pected  to  match a newline. If the PCRE2_EXTRA_ESCAPED_CR_IS_LF option
+       is set, \r in a pattern is converted to \n so  that  it  matches  a  LF
+       (linefeed) instead of a CR (carriage return) character.
+
+       An  error  occurs if \c is not followed by a character whose ASCII code
+       point is in the range 32 to 126. The precise effect of \cx is  as  fol-
+       lows:  if x is a lower case letter, it is converted to upper case. Then
+       bit 6 of the character (hex 40) is inverted. Thus \cA to \cZ become hex
+       01 to hex 1A (A is 41, Z is 5A), but \c{ becomes hex 3B ({ is 7B),  and
+       \c;  becomes hex 7B (; is 3B). If the code unit following \c has a code
+       point less than 32 or greater than 126, a compile-time error occurs.
+
+       When PCRE2 is compiled in EBCDIC mode, \N{U+hhh..}  is  not  supported.
+       \a, \e, \f, \n, \r, and \t generate the appropriate EBCDIC code values.
+       The \c escape is processed as specified for Perl in the perlebcdic doc-
+       ument.  The  only characters that are allowed after \c are A-Z, a-z, or
+       one of @, [, \, ], ^, _, or ?. Any other character provokes a  compile-
+       time  error.  The  sequence  \c@ encodes character code 0; after \c the
+       letters (in either case) encode characters 1-26 (hex 01 to hex 1A);  [,
+       \,  ], ^, and _ encode characters 27-31 (hex 1B to hex 1F), and \c? be-
+       comes either 255 (hex FF) or 95 (hex 5F).
+
+       Thus, apart from \c?, these escapes generate the  same  character  code
+       values  as  they do in an ASCII environment, though the meanings of the
+       values mostly differ. For example, \cG always generates code  value  7,
+       which is BEL in ASCII but DEL in EBCDIC.
+
+       The  sequence  \c? generates DEL (127, hex 7F) in an ASCII environment,
+       but because 127 is not a control character in  EBCDIC,  Perl  makes  it
+       generate  the  APC character. Unfortunately, there are several variants
+       of EBCDIC. In most of them the APC character has  the  value  255  (hex
+       FF),  but  in  the one Perl calls POSIX-BC its value is 95 (hex 5F). If
+       certain other characters have POSIX-BC values, PCRE2 makes \c? generate
+       95; otherwise it generates 255.
+
+       After \0 up to two further octal digits are read. If  there  are  fewer
+       than  two  digits,  just  those that are present are used. Thus the se-
+       quence \0\x\015 specifies two binary zeros followed by a  CR  character
+       (code value 13). Make sure you supply two digits after the initial zero
+       if the pattern character that follows is itself an octal digit.
+
+       The  escape \o must be followed by a sequence of octal digits, enclosed
+       in braces. An error occurs if this is not the case. This  escape  is  a
+       recent  addition  to Perl; it provides way of specifying character code
+       points as octal numbers greater than 0777, and  it  also  allows  octal
+       numbers and backreferences to be unambiguously specified.
+
+       For greater clarity and unambiguity, it is best to avoid following \ by
+       a  digit  greater than zero. Instead, use \o{...} or \x{...} to specify
+       numerical character code points, and \g{...} to specify backreferences.
+       The following paragraphs describe the old, ambiguous syntax.
+
+       The handling of a backslash followed by a digit other than 0 is compli-
+       cated, and Perl has changed over time, causing PCRE2 also to change.
+
+       Outside a character class, PCRE2 reads the digit and any following dig-
+       its as a decimal number. If the number is less than 10, begins with the
+       digit 8 or 9, or if there are  at  least  that  many  previous  capture
+       groups  in the expression, the entire sequence is taken as a backrefer-
+       ence. A description of how this works is  given  later,  following  the
+       discussion  of parenthesized groups.  Otherwise, up to three octal dig-
+       its are read to form a character code.
+
+       Inside a character class, PCRE2 handles \8 and \9 as the literal  char-
+       acters  "8"  and "9", and otherwise reads up to three octal digits fol-
+       lowing the backslash, using them to generate a data character. Any sub-
+       sequent digits stand for themselves. For example, outside  a  character
+       class:
+
+         \040   is another way of writing an ASCII space
+         \40    is the same, provided there are fewer than 40
+                   previous capture groups
+         \7     is always a backreference
+         \11    might be a backreference, or another way of
+                   writing a tab
+         \011   is always a tab
+         \0113  is a tab followed by the character "3"
+         \113   might be a backreference, otherwise the
+                   character with octal code 113
+         \377   might be a backreference, otherwise
+                   the value 255 (decimal)
+         \81    is always a backreference
+
+       Note  that octal values of 100 or greater that are specified using this
+       syntax must not be introduced by a leading zero, because no  more  than
+       three octal digits are ever read.
+
+   Constraints on character values
+
+       Characters  that  are  specified using octal or hexadecimal numbers are
+       limited to certain values, as follows:
+
+         8-bit non-UTF mode    no greater than 0xff
+         16-bit non-UTF mode   no greater than 0xffff
+         32-bit non-UTF mode   no greater than 0xffffffff
+         All UTF modes         no greater than 0x10ffff and a valid code point
+
+       Invalid Unicode code points are all those in the range 0xd800 to 0xdfff
+       (the so-called "surrogate" code points). The check  for  these  can  be
+       disabled  by  the  caller  of  pcre2_compile()  by  setting  the option
+       PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES. However, this is possible only  in
+       UTF-8  and  UTF-32 modes, because these values are not representable in
+       UTF-16.
+
+   Escape sequences in character classes
+
+       All the sequences that define a single character value can be used both
+       inside and outside character classes. In addition, inside  a  character
+       class, \b is interpreted as the backspace character (hex 08).
+
+       When not followed by an opening brace, \N is not allowed in a character
+       class.   \B,  \R, and \X are not special inside a character class. Like
+       other unrecognized alphabetic escape sequences, they  cause  an  error.
+       Outside a character class, these sequences have different meanings.
+
+   Unsupported escape sequences
+
+       In  Perl,  the  sequences  \F, \l, \L, \u, and \U are recognized by its
+       string handler and used to modify the case of following characters.  By
+       default,  PCRE2  does  not  support these escape sequences in patterns.
+       However, if either of the PCRE2_ALT_BSUX  or  PCRE2_EXTRA_ALT_BSUX  op-
+       tions  is set, \U matches a "U" character, and \u can be used to define
+       a character by code point, as described above.
+
+   Absolute and relative backreferences
+
+       The sequence \g followed by a signed or unsigned number, optionally en-
+       closed in braces, is an absolute or  relative  backreference.  A  named
+       backreference  can  be  coded as \g{name}. Backreferences are discussed
+       later, following the discussion of parenthesized groups.
+
+   Absolute and relative subroutine calls
+
+       For compatibility with Oniguruma, the non-Perl syntax \g followed by  a
+       name or a number enclosed either in angle brackets or single quotes, is
+       an  alternative syntax for referencing a capture group as a subroutine.
+       Details are discussed later.   Note  that  \g{...}  (Perl  syntax)  and
+       \g<...> (Oniguruma syntax) are not synonymous. The former is a backref-
+       erence; the latter is a subroutine call.
+
+   Generic character types
+
+       Another use of backslash is for specifying generic character types:
+
+         \d     any decimal digit
+         \D     any character that is not a decimal digit
+         \h     any horizontal white space character
+         \H     any character that is not a horizontal white space character
+         \N     any character that is not a newline
+         \s     any white space character
+         \S     any character that is not a white space character
+         \v     any vertical white space character
+         \V     any character that is not a vertical white space character
+         \w     any "word" character
+         \W     any "non-word" character
+
+       The  \N  escape  sequence has the same meaning as the "." metacharacter
+       when PCRE2_DOTALL is not set, but setting PCRE2_DOTALL does not  change
+       the meaning of \N. Note that when \N is followed by an opening brace it
+       has a different meaning. See the section entitled "Non-printing charac-
+       ters"  above for details. Perl also uses \N{name} to specify characters
+       by Unicode name; PCRE2 does not support this.
+
+       Each pair of lower and upper case escape sequences partitions the  com-
+       plete  set  of  characters  into two disjoint sets. Any given character
+       matches one, and only one, of each pair. The sequences can appear  both
+       inside  and outside character classes. They each match one character of
+       the appropriate type. If the current matching point is at  the  end  of
+       the  subject string, all of them fail, because there is no character to
+       match.
+
+       The default \s characters are HT (9), LF (10), VT  (11),  FF  (12),  CR
+       (13),  and  space (32), which are defined as white space in the "C" lo-
+       cale. This list may vary if locale-specific matching is  taking  place.
+       For  example, in some locales the "non-breaking space" character (\xA0)
+       is recognized as white space, and in others the VT character is not.
+
+       A "word" character is an underscore or any character that is  a  letter
+       or  digit.   By  default,  the definition of letters and digits is con-
+       trolled by PCRE2's low-valued character tables, and may vary if locale-
+       specific matching is taking place (see "Locale support" in the pcre2api
+       page). For example, in a French locale such  as  "fr_FR"  in  Unix-like
+       systems,  or "french" in Windows, some character codes greater than 127
+       are used for accented letters, and these are then matched  by  \w.  The
+       use of locales with Unicode is discouraged.
+
+       By  default,  characters  whose  code points are greater than 127 never
+       match \d, \s, or \w, and always match \D, \S, and \W, although this may
+       be different for characters in the range 128-255  when  locale-specific
+       matching  is  happening.   These escape sequences retain their original
+       meanings from before Unicode support was available,  mainly  for  effi-
+       ciency  reasons.  If  the  PCRE2_UCP  option  is  set, the behaviour is
+       changed so that Unicode properties  are  used  to  determine  character
+       types, as follows:
+
+         \d  any character that matches \p{Nd} (decimal digit)
+         \s  any character that matches \p{Z} or \h or \v
+         \w  any character that matches \p{L}, \p{N}, \p{Mn}, or \p{Pc}
+
+       The addition of \p{Mn} (non-spacing mark) and the replacement of an ex-
+       plicit  test  for underscore with a test for \p{Pc} (connector punctua-
+       tion) happened in PCRE2 release 10.43. This brings PCRE2 into line with
+       Perl.
+
+       The upper case escapes match the inverse sets of characters. Note  that
+       \d  matches  only decimal digits, whereas \w matches any Unicode digit,
+       as well as other character categories. Note also that PCRE2_UCP affects
+       \b, and \B because they are defined in terms of  \w  and  \W.  Matching
+       these sequences is noticeably slower when PCRE2_UCP is set.
+
+       The  effect  of  PCRE2_UCP  on any one of these escape sequences can be
+       negated by the  options  PCRE2_EXTRA_ASCII_BSD,  PCRE2_EXTRA_ASCII_BSS,
+       and  PCRE2_EXTRA_ASCII_BSW,  respectively. These options can be set and
+       reset within a pattern by means of an internal option setting (see  be-
+       low).
+
+       The  sequences  \h, \H, \v, and \V, in contrast to the other sequences,
+       which match only ASCII characters by default, always match  a  specific
+       list  of  code  points, whether or not PCRE2_UCP is set. The horizontal
+       space characters are:
+
+         U+0009     Horizontal tab (HT)
+         U+0020     Space
+         U+00A0     Non-break space
+         U+1680     Ogham space mark
+         U+180E     Mongolian vowel separator
+         U+2000     En quad
+         U+2001     Em quad
+         U+2002     En space
+         U+2003     Em space
+         U+2004     Three-per-em space
+         U+2005     Four-per-em space
+         U+2006     Six-per-em space
+         U+2007     Figure space
+         U+2008     Punctuation space
+         U+2009     Thin space
+         U+200A     Hair space
+         U+202F     Narrow no-break space
+         U+205F     Medium mathematical space
+         U+3000     Ideographic space
+
+       The vertical space characters are:
+
+         U+000A     Linefeed (LF)
+         U+000B     Vertical tab (VT)
+         U+000C     Form feed (FF)
+         U+000D     Carriage return (CR)
+         U+0085     Next line (NEL)
+         U+2028     Line separator
+         U+2029     Paragraph separator
+
+       In 8-bit, non-UTF-8 mode, only the characters  with  code  points  less
+       than 256 are relevant.
+
+   Newline sequences
+
+       Outside  a  character class, by default, the escape sequence \R matches
+       any Unicode newline sequence. In 8-bit non-UTF-8 mode \R is  equivalent
+       to the following:
+
+         (?>\r\n|\n|\x0b|\f|\r|\x85)
+
+       This is an example of an "atomic group", details of which are given be-
+       low.   This  particular group matches either the two-character sequence
+       CR followed by LF, or  one  of  the  single  characters  LF  (linefeed,
+       U+000A),  VT  (vertical  tab, U+000B), FF (form feed, U+000C), CR (car-
+       riage return, U+000D), or NEL (next line, U+0085). Because this  is  an
+       atomic  group,  the  two-character sequence is treated as a single unit
+       that cannot be split.
+
+       In other modes, two additional characters whose code points are greater
+       than 255 are added: LS (line separator, U+2028) and PS (paragraph sepa-
+       rator, U+2029).  Unicode support is not needed for these characters  to
+       be recognized.
+
+       It is possible to restrict \R to match only CR, LF, or CRLF (instead of
+       the  complete  set  of  Unicode  line  endings)  by  setting the option
+       PCRE2_BSR_ANYCRLF at compile time. (BSR is an abbreviation  for  "back-
+       slash R".) This can be made the default when PCRE2 is built; if this is
+       the  case,  the other behaviour can be requested via the PCRE2_BSR_UNI-
+       CODE option. It is also possible to specify these settings by  starting
+       a pattern string with one of the following sequences:
+
+         (*BSR_ANYCRLF)   CR, LF, or CRLF only
+         (*BSR_UNICODE)   any Unicode newline sequence
+
+       These override the default and the options given to the compiling func-
+       tion.  Note that these special settings, which are not Perl-compatible,
+       are  recognized only at the very start of a pattern, and that they must
+       be in upper case. If more than one of them is present, the last one  is
+       used. They can be combined with a change of newline convention; for ex-
+       ample, a pattern can start with:
+
+         (*ANY)(*BSR_ANYCRLF)
+
+       They  can also be combined with the (*UTF) or (*UCP) special sequences.
+       Inside a character class, \R is treated as an unrecognized  escape  se-
+       quence, and causes an error.
+
+   Unicode character properties
+
+       When  PCRE2  is  built  with Unicode support (the default), three addi-
+       tional escape sequences that match characters with specific  properties
+       are available. They can be used in any mode, though in 8-bit and 16-bit
+       non-UTF  modes these sequences are of course limited to testing charac-
+       ters whose code points are less than U+0100 and U+10000,  respectively.
+       In  32-bit non-UTF mode, code points greater than 0x10ffff (the Unicode
+       limit) may be encountered. These are all treated as being  in  the  Un-
+       known script and with an unassigned type.
+
+       Matching  characters by Unicode property is not fast, because PCRE2 has
+       to do a multistage table lookup in order to find  a  character's  prop-
+       erty. That is why the traditional escape sequences such as \d and \w do
+       not  use  Unicode  properties  in PCRE2 by default, though you can make
+       them do so by setting the PCRE2_UCP option or by starting  the  pattern
+       with (*UCP).
+
+       The extra escape sequences that provide property support are:
+
+         \p{xx}   a character with the xx property
+         \P{xx}   a character without the xx property
+         \X       a Unicode extended grapheme cluster
+
+       The  property names represented by xx above are not case-sensitive, and
+       in accordance with Unicode's "loose matching" rules,  spaces,  hyphens,
+       and underscores are ignored. There is support for Unicode script names,
+       Unicode general category properties, "Any", which matches any character
+       (including  newline),  Bidi_Class,  a number of binary (yes/no) proper-
+       ties, and some special PCRE2  properties  (described  below).   Certain
+       other  Perl  properties such as "InMusicalSymbols" are not supported by
+       PCRE2. Note that \P{Any} does  not  match  any  characters,  so  always
+       causes a match failure.
+
+   Script properties for \p and \P
+
+       There are three different syntax forms for matching a script. Each Uni-
+       code  character  has  a  basic  script and, optionally, a list of other
+       scripts ("Script Extensions") with which it is commonly used. Using the
+       Adlam script as an example, \p{sc:Adlam} matches characters whose basic
+       script is Adlam, whereas \p{scx:Adlam} matches, in addition, characters
+       that have Adlam in their extensions list. The full names  "script"  and
+       "script extensions" for the property types are recognized, and a equals
+       sign  is an alternative to the colon. If a script name is given without
+       a property type, for example, \p{Adlam}, it is  treated  as  \p{scx:Ad-
+       lam}.  Perl  changed  to  this interpretation at release 5.26 and PCRE2
+       changed at release 10.40.
+
+       Unassigned characters (and in non-UTF 32-bit mode, characters with code
+       points greater than 0x10FFFF) are assigned the "Unknown" script. Others
+       that are not part of an identified script are lumped together as  "Com-
+       mon". The current list of recognized script names and their 4-character
+       abbreviations can be obtained by running this command:
+
+         pcre2test -LS
+
+
+   The general category property for \p and \P
+
+       Each character has exactly one Unicode general category property, spec-
+       ified  by a two-letter abbreviation. For compatibility with Perl, nega-
+       tion can be specified by including a  circumflex  between  the  opening
+       brace  and  the  property  name.  For  example,  \p{^Lu} is the same as
+       \P{Lu}.
+
+       If only one letter is specified with \p or \P, it includes all the gen-
+       eral category properties that start with that letter. In this case,  in
+       the  absence of negation, the curly brackets in the escape sequence are
+       optional; these two examples have the same effect:
+
+         \p{L}
+         \pL
+
+       The following general category property codes are supported:
+
+         C     Other
+         Cc    Control
+         Cf    Format
+         Cn    Unassigned
+         Co    Private use
+         Cs    Surrogate
+
+         L     Letter
+         Ll    Lower case letter
+         Lm    Modifier letter
+         Lo    Other letter
+         Lt    Title case letter
+         Lu    Upper case letter
+
+         M     Mark
+         Mc    Spacing mark
+         Me    Enclosing mark
+         Mn    Non-spacing mark
+
+         N     Number
+         Nd    Decimal number
+         Nl    Letter number
+         No    Other number
+
+         P     Punctuation
+         Pc    Connector punctuation
+         Pd    Dash punctuation
+         Pe    Close punctuation
+         Pf    Final punctuation
+         Pi    Initial punctuation
+         Po    Other punctuation
+         Ps    Open punctuation
+
+         S     Symbol
+         Sc    Currency symbol
+         Sk    Modifier symbol
+         Sm    Mathematical symbol
+         So    Other symbol
+
+         Z     Separator
+         Zl    Line separator
+         Zp    Paragraph separator
+         Zs    Space separator
+
+       The special property LC, which has the synonym L&, is  also  supported:
+       it  matches  a  character that has the Lu, Ll, or Lt property, in other
+       words, a letter that is not classified as a modifier or "other".
+
+       The Cs (Surrogate) property  applies  only  to  characters  whose  code
+       points  are in the range U+D800 to U+DFFF. These characters are no dif-
+       ferent to any other character when PCRE2 is not in UTF mode (using  the
+       16-bit  or  32-bit  library).   However,  they are not valid in Unicode
+       strings and so cannot be tested by PCRE2 in UTF mode, unless UTF valid-
+       ity  checking  has   been   turned   off   (see   the   discussion   of
+       PCRE2_NO_UTF_CHECK in the pcre2api page).
+
+       The  long  synonyms  for  property  names  that  Perl supports (such as
+       \p{Letter}) are not supported by PCRE2, nor is it permitted  to  prefix
+       any of these properties with "Is".
+
+       No character that is in the Unicode table has the Cn (unassigned) prop-
+       erty.  Instead, this property is assumed for any code point that is not
+       in the Unicode table.
+
+       Specifying  caseless  matching  does not affect these escape sequences.
+       For example, \p{Lu} always matches only upper  case  letters.  This  is
+       different from the behaviour of current versions of Perl.
+
+   Binary (yes/no) properties for \p and \P
+
+       Unicode  defines  a  number  of  binary properties, that is, properties
+       whose only values are true or false. You can obtain  a  list  of  those
+       that  are  recognized  by \p and \P, along with their abbreviations, by
+       running this command:
+
+         pcre2test -LP
+
+
+   The Bidi_Class property for \p and \P
+
+         \p{Bidi_Class:}   matches a character with the given class
+         \p{BC:}           matches a character with the given class
+
+       The recognized classes are:
+
+         AL          Arabic letter
+         AN          Arabic number
+         B           paragraph separator
+         BN          boundary neutral
+         CS          common separator
+         EN          European number
+         ES          European separator
+         ET          European terminator
+         FSI         first strong isolate
+         L           left-to-right
+         LRE         left-to-right embedding
+         LRI         left-to-right isolate
+         LRO         left-to-right override
+         NSM         non-spacing mark
+         ON          other neutral
+         PDF         pop directional format
+         PDI         pop directional isolate
+         R           right-to-left

+         RLI         right-to-left isolate
+         RLO         right-to-left override
+         S           segment separator
+         WS          which space
+
+       An equals sign may be used instead of a  colon.  The  class  names  are
+       case-insensitive; only the short names listed above are recognized.
+
+   Extended grapheme clusters
+
+       The  \X  escape  matches  any number of Unicode characters that form an
+       "extended grapheme cluster", and treats the sequence as an atomic group
+       (see below).  Unicode supports various kinds of composite character  by
+       giving  each  character  a grapheme breaking property, and having rules
+       that use these properties to define the boundaries of extended grapheme
+       clusters. The rules are defined in Unicode Standard Annex 29,  "Unicode
+       Text  Segmentation".  Unicode 11.0.0 abandoned the use of some previous
+       properties that had been used for emojis.  Instead it introduced  vari-
+       ous  emoji-specific  properties.  PCRE2  uses  only the Extended Picto-
+       graphic property.
+
+       \X always matches at least one character. Then it  decides  whether  to
+       add additional characters according to the following rules for ending a
+       cluster:
+
+       1. End at the end of the subject string.
+
+       2.  Do not end between CR and LF; otherwise end after any control char-
+       acter.
+
+       3. Do not break Hangul (a Korean  script)  syllable  sequences.  Hangul
+       characters  are of five types: L, V, T, LV, and LVT. An L character may
+       be followed by an L, V, LV, or LVT character; an LV or V character  may
+       be  followed  by  a V or T character; an LVT or T character may be fol-
+       lowed only by a T character.
+
+       4. Do not end before extending characters or spacing marks or the zero-
+       width joiner (ZWJ) character. Characters with the "mark"  property  al-
+       ways have the "extend" grapheme breaking property.
+
+       5. Do not end after prepend characters.
+
+       6.  Do not end within emoji modifier sequences or emoji ZWJ (zero-width
+       joiner) sequences. An emoji ZWJ sequence consists of a  character  with
+       the  Extended_Pictographic property, optionally followed by one or more
+       characters with the Extend property, followed  by  the  ZWJ  character,
+       followed by another Extended_Pictographic character.
+
+       7.  Do not break within emoji flag sequences. That is, do not break be-
+       tween regional indicator (RI) characters if there are an odd number  of
+       RI characters before the break point.
+
+       8. Otherwise, end the cluster.
+
+   PCRE2's additional properties
+
+       As  well as the standard Unicode properties described above, PCRE2 sup-
+       ports four more that make it possible to convert traditional escape se-
+       quences such as \w and \s to use Unicode properties. PCRE2  uses  these
+       non-standard,  non-Perl  properties  internally  when PCRE2_UCP is set.
+       However, they may also be used explicitly. These properties are:
+
+         Xan   Any alphanumeric character
+         Xps   Any POSIX space character
+         Xsp   Any Perl space character
+         Xwd   Any Perl "word" character
+
+       Xan matches characters that have either the L (letter) or the  N  (num-
+       ber)  property. Xps matches the characters tab, linefeed, vertical tab,
+       form feed, or carriage return, and any other character that has  the  Z
+       (separator)  property.  Xsp is the same as Xps; in PCRE1 it used to ex-
+       clude vertical tab, for  Perl  compatibility,  but  Perl  changed.  Xwd
+       matches the same characters as Xan, plus those that match Mn (non-spac-
+       ing mark) or Pc (connector punctuation, which includes underscore).
+
+       There  is another non-standard property, Xuc, which matches any charac-
+       ter that can be represented by a Universal Character Name  in  C++  and
+       other  programming  languages.  These are the characters $, @, ` (grave
+       accent), and all characters with Unicode code points  greater  than  or
+       equal  to U+00A0, except for the surrogates U+D800 to U+DFFF. Note that
+       most base (ASCII) characters are excluded. (Universal  Character  Names
+       are  of  the  form \uHHHH or \UHHHHHHHH where H is a hexadecimal digit.
+       Note that the Xuc property does not match these sequences but the char-
+       acters that they represent.)
+
+   Resetting the match start
+
+       In normal use, the escape sequence \K  causes  any  previously  matched
+       characters not to be included in the final matched sequence that is re-
+       turned. For example, the pattern:
+
+         foo\Kbar
+
+       matches  "foobar",  but  reports that it has matched "bar". \K does not
+       interact with anchoring in any way. The pattern:
+
+         ^foo\Kbar
+
+       matches only when the subject begins  with  "foobar"  (in  single  line
+       mode),  though  it again reports the matched string as "bar". This fea-
+       ture is similar to a lookbehind assertion (described  below),  but  the
+       part of the pattern that precedes \K is not constrained to match a lim-
+       ited  number  of characters, as is required for a lookbehind assertion.
+       The use of \K does not interfere with  the  setting  of  captured  sub-
+       strings.  For example, when the pattern
+
+         (foo)\Kbar
+
+       matches "foobar", the first substring is still set to "foo".
+
+       From  version  5.32.0  Perl  forbids the use of \K in lookaround asser-
+       tions. From release 10.38 PCRE2 also forbids this by default.  However,
+       the  PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK  option  can be used when calling
+       pcre2_compile() to re-enable the previous behaviour. When  this  option
+       is set, \K is acted upon when it occurs inside positive assertions, but
+       is  ignored  in  negative  assertions. Note that when a pattern such as
+       (?=ab\K) matches, the reported start of the match can be  greater  than
+       the  end  of the match. Using \K in a lookbehind assertion at the start
+       of a pattern can also lead to odd effects. For example,  consider  this
+       pattern:
+
+         (?<=\Kfoo)bar
+
+       If  the  subject  is  "foobar", a call to pcre2_match() with a starting
+       offset of 3 succeeds and reports the matching string as "foobar",  that
+       is,  the  start  of  the reported match is earlier than where the match
+       started.
+
+   Simple assertions
+
+       The final use of backslash is for certain simple assertions. An  asser-
+       tion  specifies a condition that has to be met at a particular point in
+       a match, without consuming any characters from the subject string.  The
+       use  of groups for more complicated assertions is described below.  The
+       backslashed assertions are:
+
+         \b     matches at a word boundary
+         \B     matches when not at a word boundary
+         \A     matches at the start of the subject
+         \Z     matches at the end of the subject
+                 also matches before a newline at the end of the subject
+         \z     matches only at the end of the subject
+         \G     matches at the first matching position in the subject
+
+       Inside a character class, \b has a different meaning;  it  matches  the
+       backspace  character.  If  any  other  of these assertions appears in a
+       character class, an "invalid escape sequence" error is generated.
+
+       A word boundary is a position in the subject string where  the  current
+       character  and  the previous character do not both match \w or \W (i.e.
+       one matches \w and the other matches \W), or the start or  end  of  the
+       string  if  the  first or last character matches \w, respectively. When
+       PCRE2 is built with Unicode support, the meanings of \w and \W  can  be
+       changed by setting the PCRE2_UCP option. When this is done, it also af-
+       fects  \b and \B. Neither PCRE2 nor Perl has a separate "start of word"
+       or "end of word" metasequence. However, whatever  follows  \b  normally
+       determines  which  it  is. For example, the fragment \ba matches "a" at
+       the start of a word.
+
+       The \A, \Z, and \z assertions differ from  the  traditional  circumflex
+       and dollar (described in the next section) in that they only ever match
+       at  the  very start and end of the subject string, whatever options are
+       set. Thus, they are independent of multiline mode. These  three  asser-
+       tions  are  not  affected  by the PCRE2_NOTBOL or PCRE2_NOTEOL options,
+       which affect only the behaviour of the circumflex and dollar  metachar-
+       acters.  However,  if the startoffset argument of pcre2_match() is non-
+       zero, indicating that matching is to start at a point  other  than  the
+       beginning  of  the subject, \A can never match.  The difference between
+       \Z and \z is that \Z matches before a newline at the end of the  string
+       as well as at the very end, whereas \z matches only at the end.
+
+       The  \G assertion is true only when the current matching position is at
+       the start point of the matching process, as specified by the  startoff-
+       set  argument  of  pcre2_match().  It differs from \A when the value of
+       startoffset is non-zero. By calling pcre2_match() multiple  times  with
+       appropriate  arguments,  you  can  mimic Perl's /g option, and it is in
+       this kind of implementation where \G can be useful.
+
+       Note, however, that PCRE2's implementation of \G,  being  true  at  the
+       starting  character  of  the matching process, is subtly different from
+       Perl's, which defines it as true at the end of the previous  match.  In
+       Perl,  these  can  be  different when the previously matched string was
+       empty. Because PCRE2 does just one match at a time, it cannot reproduce
+       this behaviour.
+
+       If all the alternatives of a pattern begin with \G, the  expression  is
+       anchored to the starting match position, and the "anchored" flag is set
+       in the compiled regular expression.
+
+
+CIRCUMFLEX AND DOLLAR
+
+       The  circumflex  and  dollar  metacharacters are zero-width assertions.
+       That is, they test for a particular condition being true  without  con-
+       suming any characters from the subject string. These two metacharacters
+       are  concerned  with matching the starts and ends of lines. If the new-
+       line convention is set so that only the two-character sequence CRLF  is
+       recognized  as  a newline, isolated CR and LF characters are treated as
+       ordinary data characters, and are not recognized as newlines.
+
+       Outside a character class, in the default matching mode, the circumflex
+       character is an assertion that is true only  if  the  current  matching
+       point  is  at the start of the subject string. If the startoffset argu-
+       ment of pcre2_match() is non-zero, or if PCRE2_NOTBOL is  set,  circum-
+       flex  can  never match if the PCRE2_MULTILINE option is unset. Inside a
+       character class, circumflex has an entirely different meaning (see  be-
+       low).
+
+       Circumflex  need  not be the first character of the pattern if a number
+       of alternatives are involved, but it should be the first thing in  each
+       alternative  in  which  it appears if the pattern is ever to match that
+       branch. If all possible alternatives start with a circumflex, that  is,
+       if  the  pattern  is constrained to match only at the start of the sub-
+       ject, it is said to be an "anchored" pattern.  (There  are  also  other
+       constructs that can cause a pattern to be anchored.)
+
+       The  dollar  character is an assertion that is true only if the current
+       matching point is at the end of the subject string, or immediately  be-
+       fore  a newline at the end of the string (by default), unless PCRE2_NO-
+       TEOL is set. Note, however, that it does not actually  match  the  new-
+       line.  Dollar need not be the last character of the pattern if a number
+       of alternatives are involved, but it should be the  last  item  in  any
+       branch  in which it appears. Dollar has no special meaning in a charac-
+       ter class.
+
+       The meaning of dollar can be changed so that it  matches  only  at  the
+       very  end  of the string, by setting the PCRE2_DOLLAR_ENDONLY option at
+       compile time. This does not affect the \Z assertion.
+
+       The meanings of the circumflex and dollar metacharacters are changed if
+       the PCRE2_MULTILINE option is set. When this  is  the  case,  a  dollar
+       character  matches before any newlines in the string, as well as at the
+       very end, and a circumflex matches immediately after internal  newlines
+       as  well as at the start of the subject string. It does not match after
+       a newline that ends the string, for compatibility with  Perl.  However,
+       this can be changed by setting the PCRE2_ALT_CIRCUMFLEX option.
+
+       For  example, the pattern /^abc$/ matches the subject string "def\nabc"
+       (where \n represents a newline) in multiline mode, but  not  otherwise.
+       Consequently,  patterns  that  are anchored in single line mode because
+       all branches start with ^ are not anchored in  multiline  mode,  and  a
+       match  for  circumflex  is  possible  when  the startoffset argument of
+       pcre2_match() is non-zero. The PCRE2_DOLLAR_ENDONLY option  is  ignored
+       if PCRE2_MULTILINE is set.
+
+       When  the  newline  convention (see "Newline conventions" below) recog-
+       nizes the two-character sequence CRLF as a newline, this is  preferred,
+       even  if  the  single  characters CR and LF are also recognized as new-
+       lines. For example, if the newline convention  is  "any",  a  multiline
+       mode  circumflex matches before "xyz" in the string "abc\r\nxyz" rather
+       than after CR, even though CR on its own is a valid newline.  (It  also
+       matches at the very start of the string, of course.)
+
+       Note  that  the sequences \A, \Z, and \z can be used to match the start
+       and end of the subject in both modes, and if all branches of a  pattern
+       start  with \A it is always anchored, whether or not PCRE2_MULTILINE is
+       set.
+
+
+FULL STOP (PERIOD, DOT) AND \N
+
+       Outside a character class, a dot in the pattern matches any one charac-
+       ter in the subject string except (by default) a character  that  signi-
+       fies the end of a line. One or more characters may be specified as line
+       terminators (see "Newline conventions" above).
+
+       Dot  never matches a single line-ending character. When the two-charac-
+       ter sequence CRLF is the only line ending, dot does not match CR if  it
+       is  immediately followed by LF, but otherwise it matches all characters
+       (including isolated CRs and LFs). When ANYCRLF  is  selected  for  line
+       endings,  no  occurrences  of CR of LF match dot. When all Unicode line
+       endings are being recognized, dot does not match CR or LF or any of the
+       other line ending characters.
+
+       The behaviour of dot with regard to newlines can  be  changed.  If  the
+       PCRE2_DOTALL  option  is  set, a dot matches any one character, without
+       exception.  If the two-character sequence CRLF is present in  the  sub-
+       ject string, it takes two dots to match it.
+
+       The  handling of dot is entirely independent of the handling of circum-
+       flex and dollar, the only relationship being  that  they  both  involve
+       newlines. Dot has no special meaning in a character class.
+
+       The  escape  sequence  \N when not followed by an opening brace behaves
+       like a dot, except that it is not affected by the PCRE2_DOTALL  option.
+       In  other words, it matches any character except one that signifies the
+       end of a line.
+
+       When \N is followed by an opening brace it has a different meaning. See
+       the section entitled "Non-printing characters" above for details.  Perl
+       also  uses  \N{name}  to specify characters by Unicode name; PCRE2 does
+       not support this.
+
+
+MATCHING A SINGLE CODE UNIT
+
+       Outside a character class, the escape sequence \C matches any one  code
+       unit,  whether or not a UTF mode is set. In the 8-bit library, one code
+       unit is one byte; in the 16-bit library it is a  16-bit  unit;  in  the
+       32-bit  library  it  is  a 32-bit unit. Unlike a dot, \C always matches
+       line-ending characters. The feature is provided in  Perl  in  order  to
+       match individual bytes in UTF-8 mode, but it is unclear how it can use-
+       fully be used.
+
+       Because  \C  breaks  up characters into individual code units, matching
+       one unit with \C in UTF-8 or UTF-16 mode means that  the  rest  of  the
+       string may start with a malformed UTF character. This has undefined re-
+       sults, because PCRE2 assumes that it is matching character by character
+       in a valid UTF string (by default it checks the subject string's valid-
+       ity  at  the  start  of  processing  unless  the  PCRE2_NO_UTF_CHECK or
+       PCRE2_MATCH_INVALID_UTF option is used).
+
+       An  application  can  lock  out  the  use  of   \C   by   setting   the
+       PCRE2_NEVER_BACKSLASH_C  option  when  compiling  a pattern. It is also
+       possible to build PCRE2 with the use of \C permanently disabled.
+
+       PCRE2 does not allow \C to appear in lookbehind  assertions  (described
+       below)  in UTF-8 or UTF-16 modes, because this would make it impossible
+       to calculate the length of  the  lookbehind.  Neither  the  alternative
+       matching function pcre2_dfa_match() nor the JIT optimizer support \C in
+       these UTF modes.  The former gives a match-time error; the latter fails
+       to optimize and so the match is always run using the interpreter.
+
+       In  the  32-bit  library, however, \C is always supported (when not ex-
+       plicitly locked out) because it always  matches  a  single  code  unit,
+       whether or not UTF-32 is specified.
+
+       In general, the \C escape sequence is best avoided. However, one way of
+       using  it  that avoids the problem of malformed UTF-8 or UTF-16 charac-
+       ters is to use a lookahead to check the length of the  next  character,
+       as  in  this  pattern,  which could be used with a UTF-8 string (ignore
+       white space and line breaks):
+
+         (?| (?=[\x00-\x7f])(\C) |
+             (?=[\x80-\x{7ff}])(\C)(\C) |
+             (?=[\x{800}-\x{ffff}])(\C)(\C)(\C) |
+             (?=[\x{10000}-\x{1fffff}])(\C)(\C)(\C)(\C))
+
+       In this example, a group that starts  with  (?|  resets  the  capturing
+       parentheses  numbers in each alternative (see "Duplicate Group Numbers"
+       below). The assertions at the start of each branch check the next UTF-8
+       character for values whose encoding uses 1, 2, 3, or 4  bytes,  respec-
+       tively.  The  character's individual bytes are then captured by the ap-
+       propriate number of \C groups.
+
+
+SQUARE BRACKETS AND CHARACTER CLASSES
+
+       An opening square bracket introduces a character class, terminated by a
+       closing square bracket. A closing square bracket on its own is not spe-
+       cial by default.  If a closing square bracket is required as  a  member
+       of the class, it should be the first data character in the class (after
+       an  initial  circumflex,  if present) or escaped with a backslash. This
+       means that, by default, an empty class cannot be defined.  However,  if
+       the  PCRE2_ALLOW_EMPTY_CLASS option is set, a closing square bracket at
+       the start does end the (empty) class.
+
+       A character class matches a single character in the subject. A  matched
+       character must be in the set of characters defined by the class, unless
+       the  first  character in the class definition is a circumflex, in which
+       case the subject character must not be in the set defined by the class.
+       If a circumflex is actually required as a member of the  class,  ensure
+       it is not the first character, or escape it with a backslash.
+
+       For  example, the character class [aeiou] matches any lower case vowel,
+       while [^aeiou] matches any character that is not a  lower  case  vowel.
+       Note that a circumflex is just a convenient notation for specifying the
+       characters  that  are in the class by enumerating those that are not. A
+       class that starts with a circumflex is not an assertion; it still  con-
+       sumes  a  character  from the subject string, and therefore it fails if
+       the current pointer is at the end of the string.
+
+       Characters in a class may be specified by their code points  using  \o,
+       \x,  or \N{U+hh..} in the usual way. When caseless matching is set, any
+       letters in a class represent both their upper case and lower case  ver-
+       sions,  so  for example, a caseless [aeiou] matches "A" as well as "a",
+       and a caseless [^aeiou] does not match "A", whereas a  caseful  version
+       would.  Note that there are two ASCII characters, K and S, that, in ad-
+       dition to their lower case ASCII equivalents, are case-equivalent  with
+       Unicode  U+212A (Kelvin sign) and U+017F (long S) respectively when ei-
+       ther PCRE2_UTF or PCRE2_UCP is set.
+
+       Characters that might indicate line breaks are  never  treated  in  any
+       special  way  when matching character classes, whatever line-ending se-
+       quence is  in  use,  and  whatever  setting  of  the  PCRE2_DOTALL  and
+       PCRE2_MULTILINE  options  is  used. A class such as [^a] always matches
+       one of these characters.
+
+       The generic character type escape sequences \d, \D, \h, \H, \p, \P, \s,
+       \S, \v, \V, \w, and \W may appear in a character  class,  and  add  the
+       characters  that  they  match  to  the  class.  For example, [\dABCDEF]
+       matches any hexadecimal digit. In UTF modes, the PCRE2_UCP  option  af-
+       fects the meanings of \d, \s, \w and their upper case partners, just as
+       it does when they appear outside a character class, as described in the
+       section  entitled  "Generic character types" above. The escape sequence
+       \b has a different meaning inside a character  class;  it  matches  the
+       backspace  character.  The sequences \B, \R, and \X are not special in-
+       side a character class. Like any other unrecognized  escape  sequences,
+       they  cause  an  error. The same is true for \N when not followed by an
+       opening brace.
+
+       The minus (hyphen) character can be used to specify a range of  charac-
+       ters  in  a  character class. For example, [d-m] matches any letter be-
+       tween d and m, inclusive. If a minus character is required in a  class,
+       it  must  be  escaped with a backslash or appear in a position where it
+       cannot be interpreted as indicating a range, typically as the first  or
+       last character in the class, or immediately after a range. For example,
+       [b-d-z] matches letters in the range b to d, a hyphen character, or z.
+
+       Perl treats a hyphen as a literal if it appears before or after a POSIX
+       class (see below) or before or after a character type escape such as \d
+       or  \H.  However, unless the hyphen is the last character in the class,
+       Perl outputs a warning in its warning mode, as this is  most  likely  a
+       user  error. As PCRE2 has no facility for warning, an error is given in
+       these cases.
+
+       It is not possible to have the literal character "]" as the end charac-
+       ter of a range. A pattern such as [W-]46] is interpreted as a class  of
+       two  characters ("W" and "-") followed by a literal string "46]", so it
+       would match "W46]" or "-46]". However, if the "]"  is  escaped  with  a
+       backslash  it is interpreted as the end of range, so [W-\]46] is inter-
+       preted as a class containing a range followed by two other  characters.
+       The  octal or hexadecimal representation of "]" can also be used to end
+       a range.
+
+       Ranges normally include all code points between the start and end char-
+       acters, inclusive. They can also be used for code points specified  nu-
+       merically,  for  example [\000-\037]. Ranges can include any characters
+       that are valid for the current mode. In any  UTF  mode,  the  so-called
+       "surrogate"  characters (those whose code points lie between 0xd800 and
+       0xdfff inclusive) may not  be  specified  explicitly  by  default  (the
+       PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES  option  disables this check). How-
+       ever, ranges such as [\x{d7ff}-\x{e000}], which include the surrogates,
+       are always permitted.
+
+       There is a special case in EBCDIC environments  for  ranges  whose  end
+       points are both specified as literal letters in the same case. For com-
+       patibility  with Perl, EBCDIC code points within the range that are not
+       letters are omitted. For example, [h-k] matches only  four  characters,
+       even though the codes for h and k are 0x88 and 0x92, a range of 11 code
+       points.  However,  if  the range is specified numerically, for example,
+       [\x88-\x92] or [h-\x92], all code points are included.
+
+       If a range that includes letters is used when caseless matching is set,
+       it matches the letters in either case. For example, [W-c] is equivalent
+       to [][\\^_`wxyzabc], matched caselessly, and  in  a  non-UTF  mode,  if
+       character  tables  for  a French locale are in use, [\xc8-\xcb] matches
+       accented E characters in both cases.
+
+       A circumflex can conveniently be used with  the  upper  case  character
+       types  to specify a more restricted set of characters than the matching
+       lower case type.  For example, the class [^\W_] matches any  letter  or
+       digit, but not underscore, whereas [\w] includes underscore. A positive
+       character class should be read as "something OR something OR ..." and a
+       negative class as "NOT something AND NOT something AND NOT ...".
+
+       The  only  metacharacters  that are recognized in character classes are
+       backslash, hyphen (only where it can be  interpreted  as  specifying  a
+       range),  circumflex  (only  at the start), opening square bracket (only
+       when it can be interpreted as introducing a POSIX class name, or for  a
+       special  compatibility  feature  -  see the next two sections), and the
+       terminating closing square bracket.  However,  escaping  other  non-al-
+       phanumeric characters does no harm.
+
+
+POSIX CHARACTER CLASSES
+
+       Perl supports the POSIX notation for character classes. This uses names
+       enclosed  by [: and :] within the enclosing square brackets. PCRE2 also
+       supports this notation. For example,
+
+         [01[:alpha:]%]
+
+       matches "0", "1", any alphabetic character, or "%". The supported class
+       names are:
+
+         alnum    letters and digits
+         alpha    letters
+         ascii    character codes 0 - 127
+         blank    space or tab only
+         cntrl    control characters
+         digit    decimal digits (same as \d)
+         graph    printing characters, excluding space
+         lower    lower case letters
+         print    printing characters, including space
+         punct    printing characters, excluding letters and digits and space
+         space    white space (the same as \s from PCRE2 8.34)
+         upper    upper case letters
+         word     "word" characters (same as \w)
+         xdigit   hexadecimal digits
+
+       The default "space" characters are HT (9), LF (10), VT (11),  FF  (12),
+       CR  (13),  and space (32). If locale-specific matching is taking place,
+       the list of space characters may be different; there may  be  fewer  or
+       more  of  them.  "Space" and \s match the same set of characters, as do
+       "word" and \w.
+
+       The name "word" is a Perl extension, and "blank"  is  a  GNU  extension
+       from  Perl  5.8. Another Perl extension is negation, which is indicated
+       by a ^ character after the colon. For example,
+
+         [12[:^digit:]]
+
+       matches "1", "2", or any non-digit. PCRE2 (and Perl) also recognize the
+       POSIX syntax [.ch.] and [=ch=] where "ch" is a "collating element", but
+       these are not supported, and an error is given if they are encountered.
+
+       By default, characters with values greater than 127 do not match any of
+       the POSIX character classes, although this may be different for charac-
+       ters in the range 128-255 when locale-specific matching  is  happening.
+       However,  in UCP mode, unless certain options are set (see below), some
+       of the classes are changed so that  Unicode  character  properties  are
+       used. This is achieved by replacing POSIX classes with other sequences,
+       as follows:
+
+         [:alnum:]  becomes  \p{Xan}
+         [:alpha:]  becomes  \p{L}
+         [:blank:]  becomes  \h
+         [:cntrl:]  becomes  \p{Cc}
+         [:digit:]  becomes  \p{Nd}
+         [:lower:]  becomes  \p{Ll}
+         [:space:]  becomes  \p{Xps}
+         [:upper:]  becomes  \p{Lu}
+         [:word:]   becomes  \p{Xwd}
+
+       Negated  versions,  such as [:^alpha:] use \P instead of \p. Four other
+       POSIX classes are handled specially in UCP mode:
+
+       [:graph:] This matches characters that have glyphs that mark  the  page
+                 when printed. In Unicode property terms, it matches all char-
+                 acters with the L, M, N, P, S, or Cf properties, except for:
+
+                   U+061C           Arabic Letter Mark
+                   U+180E           Mongolian Vowel Separator
+                   U+2066 - U+2069  Various "isolate"s
+
+
+       [:print:] This  matches  the  same  characters  as [:graph:] plus space
+                 characters that are not controls, that  is,  characters  with
+                 the Zs property.
+
+       [:punct:] This matches all characters that have the Unicode P (punctua-
+                 tion)  property,  plus those characters with code points less
+                 than 256 that have the S (Symbol) property.
+
+       [:xdigit:]
+                 In addition  to  the  ASCII  hexadecimal  digits,  this  also
+                 matches  the  "fullwidth" versions of those characters, whose
+                 Unicode code points start at U+FF10. This is  a  change  that
+                 was made in PCRE release 10.43 for Perl compatibility.
+
+       The  other  POSIX  classes  are  unchanged by PCRE2_UCP, and match only
+       characters with code points less than 256.
+
+       There are two options that can be used to restrict the POSIX classes to
+       ASCII  characters  when  PCRE2_UCP  is  set.   The   option   PCRE2_EX-
+       TRA_ASCII_DIGIT  affects  just  [:digit:] and [:xdigit:]. Within a pat-
+       tern, this can be set and unset by  (?aT)  and  (?-aT).  The  PCRE2_EX-
+       TRA_ASCII_POSIX  option  disables UCP processing for all POSIX classes,
+       including [:digit:] and [:xdigit:]. Within a pattern, (?aP) and  (?-aP)
+       set and unset both these options for consistency.
+
+
+COMPATIBILITY FEATURE FOR WORD BOUNDARIES
+
+       In  the POSIX.2 compliant library that was included in 4.4BSD Unix, the
+       ugly syntax [[:<:]] and [[:>:]] is used for matching  "start  of  word"
+       and "end of word". PCRE2 treats these items as follows:
+
+         [[:<:]]  is converted to  \b(?=\w)
+         [[:>:]]  is converted to  \b(?<=\w)
+
+       Only these exact character sequences are recognized. A sequence such as
+       [a[:<:]b]  provokes  error  for  an unrecognized POSIX class name. This
+       support is not compatible with Perl. It is provided to help  migrations
+       from other environments, and is best not used in any new patterns. Note
+       that  \b matches at the start and the end of a word (see "Simple asser-
+       tions" above), and in a Perl-style pattern the preceding  or  following
+       character  normally shows which is wanted, without the need for the as-
+       sertions that are used above in order to give exactly the POSIX  behav-
+       iour.  Note  also  that  the PCRE2_UCP option changes the meaning of \w
+       (and therefore \b) by default, so  it  also  affects  these  POSIX  se-
+       quences.
+
+
+VERTICAL BAR
+
+       Vertical  bar characters are used to separate alternative patterns. For
+       example, the pattern
+
+         gilbert|sullivan
+
+       matches either "gilbert" or "sullivan". Any number of alternatives  may
+       appear,  and  an  empty  alternative  is  permitted (matching the empty
+       string). The matching process tries each alternative in turn, from left
+       to right, and the first one that succeeds is used. If the  alternatives
+       are  within a group (defined below), "succeeds" means matching the rest
+       of the main pattern as well as the alternative in the group.
+
+
+INTERNAL OPTION SETTING
+
+       The settings of several options can be changed within a  pattern  by  a
+       sequence  of  letters  enclosed between "(?" and ")". The following are
+       Perl-compatible, and are described in detail in the pcre2api documenta-
+       tion. The option letters are:
+
+         i  for PCRE2_CASELESS
+         m  for PCRE2_MULTILINE
+         n  for PCRE2_NO_AUTO_CAPTURE
+         s  for PCRE2_DOTALL
+         x  for PCRE2_EXTENDED
+         xx for PCRE2_EXTENDED_MORE
+
+       For example, (?im) sets caseless, multiline matching. It is also possi-
+       ble to unset these options by preceding the relevant letters with a hy-
+       phen, for example (?-im). The two "extended" options are  not  indepen-
+       dent; unsetting either one cancels the effects of both of them.
+
+       A   combined  setting  and  unsetting  such  as  (?im-sx),  which  sets
+       PCRE2_CASELESS and PCRE2_MULTILINE  while  unsetting  PCRE2_DOTALL  and
+       PCRE2_EXTENDED,  is  also  permitted. Only one hyphen may appear in the
+       options string. If a letter appears both before and after  the  hyphen,
+       the  option  is unset. An empty options setting "(?)" is allowed. Need-
+       less to say, it has no effect.
+
+       If the first character following (? is a circumflex, it causes  all  of
+       the  above  options  to  be unset. Letters may follow the circumflex to
+       cause some options to be re-instated, but a hyphen may not appear.
+
+       Some PCRE2-specific options can be changed by the same mechanism  using
+       these pairs or individual letters:
+
+         aD for PCRE2_EXTRA_ASCII_BSD
+         aS for PCRE2_EXTRA_ASCII_BSS
+         aW for PCRE2_EXTRA_ASCII_BSW
+         aP for PCRE2_EXTRA_ASCII_POSIX and PCRE2_EXTRA_ASCII_DIGIT
+         aT for PCRE2_EXTRA_ASCII_DIGIT
+         r  for PCRE2_EXTRA_CASELESS_RESTRICT
+         J  for PCRE2_DUPNAMES
+         U  for PCRE2_UNGREEDY
+
+       However,  except for 'r', these are not unset by (?^), which is equiva-
+       lent to (?-imnrsx). If 'a' is not followed by any  of  the  upper  case
+       letters shown above, it sets (or unsets) all the ASCII options.
+
+       PCRE2_EXTRA_ASCII_DIGIT   has   no  additional  effect  when  PCRE2_EX-
+       TRA_ASCII_POSIX is set, but including it in  (?aP)  means  that  (?-aP)
+       suppresses all ASCII restrictions for POSIX classes.
+
+       When  one of these option changes occurs at top level (that is, not in-
+       side group parentheses), the change applies until a subsequent  change,
+       or  the  end of the pattern. An option change within a group (see below
+       for a description of groups) affects only that part of the  group  that
+       follows  it.  At  the  end  of the group these options are reset to the
+       state they were before the group. For example,
+
+         (a(?i)b)c
+
+       matches abc and aBc and no other strings  (assuming  PCRE2_CASELESS  is
+       not  set  externally).  Any changes made in one alternative do carry on
+       into subsequent branches within the same group. For example,
+
+         (a(?i)b|c)
+
+       matches "ab", "aB", "c", and "C", even though  when  matching  "C"  the
+       first  branch  is  abandoned before the option setting. This is because
+       the effects of option settings happen at compile time. There  would  be
+       some very weird behaviour otherwise.
+
+       As  a  convenient shorthand, if any option settings are required at the
+       start of a non-capturing group (see the next section), the option  let-
+       ters may appear between the "?" and the ":". Thus the two patterns
+
+         (?i:saturday|sunday)
+         (?:(?i)saturday|sunday)
+
+       match exactly the same set of strings.
+
+       Note:  There  are  other  PCRE2-specific options, applying to the whole
+       pattern, which can be set by the application when the  compiling  func-
+       tion  is  called.  In addition, the pattern can contain special leading
+       sequences such as (*CRLF) to override what the application has  set  or
+       what  has  been  defaulted.   Details are given in the section entitled
+       "Newline sequences" above. There are also the (*UTF) and (*UCP) leading
+       sequences that can be used to set UTF and Unicode property modes;  they
+       are  equivalent to setting the PCRE2_UTF and PCRE2_UCP options, respec-
+       tively.  However,  the  application  can  set  the  PCRE2_NEVER_UTF  or
+       PCRE2_NEVER_UCP  options,  which  lock  out  the  use of the (*UTF) and
+       (*UCP) sequences.
+
+
+GROUPS
+
+       Groups are delimited by parentheses  (round  brackets),  which  can  be
+       nested.  Turning part of a pattern into a group does two things:
+
+       1. It localizes a set of alternatives. For example, the pattern
+
+         cat(aract|erpillar|)
+
+       matches  "cataract",  "caterpillar", or "cat". Without the parentheses,
+       it would match "cataract", "erpillar" or an empty string.
+
+       2. It creates a "capture group". This means that, when the  whole  pat-
+       tern  matches, the portion of the subject string that matched the group
+       is passed back to the caller, separately from the portion that  matched
+       the  whole  pattern.   (This  applies  only to the traditional matching
+       function; the DFA matching function does not support capturing.)
+
+       Opening parentheses are counted from left to right (starting from 1) to
+       obtain numbers for capture groups. For example, if the string "the  red
+       king" is matched against the pattern
+
+         the ((red|white) (king|queen))
+
+       the captured substrings are "red king", "red", and "king", and are num-
+       bered 1, 2, and 3, respectively.
+
+       The  fact  that  plain  parentheses  fulfil two functions is not always
+       helpful.  There are often times when grouping is required without  cap-
+       turing.  If an opening parenthesis is followed by a question mark and a
+       colon, the group does not do any capturing, and  is  not  counted  when
+       computing  the number of any subsequent capture groups. For example, if
+       the string "the white queen" is matched against the pattern
+
+         the ((?:red|white) (king|queen))
+
+       the captured substrings are "white queen" and "queen", and are numbered
+       1 and 2. The maximum number of capture groups is 65535.
+
+       As a convenient shorthand, if any option settings are required  at  the
+       start  of  a non-capturing group, the option letters may appear between
+       the "?" and the ":". Thus the two patterns
+
+         (?i:saturday|sunday)
+         (?:(?i)saturday|sunday)
+
+       match exactly the same set of strings. Because alternative branches are
+       tried from left to right, and options are not reset until  the  end  of
+       the  group is reached, an option setting in one branch does affect sub-
+       sequent branches, so the above patterns match "SUNDAY" as well as "Sat-
+       urday".
+
+
+DUPLICATE GROUP NUMBERS
+
+       Perl 5.10 introduced a feature whereby each alternative in a group uses
+       the same numbers for its capturing parentheses.  Such  a  group  starts
+       with  (?|  and  is  itself a non-capturing group. For example, consider
+       this pattern:
+
+         (?|(Sat)ur|(Sun))day
+
+       Because the two alternatives are inside a (?| group, both sets of  cap-
+       turing  parentheses  are  numbered one. Thus, when the pattern matches,
+       you can look at captured substring number  one,  whichever  alternative
+       matched.  This  construct  is useful when you want to capture part, but
+       not all, of one of a number of alternatives. Inside a (?| group, paren-
+       theses are numbered as usual, but the number is reset at the  start  of
+       each  branch.  The numbers of any capturing parentheses that follow the
+       whole group start after the highest number used in any branch. The fol-
+       lowing example is taken from the Perl documentation. The numbers under-
+       neath show in which buffer the captured content will be stored.
+
+         # before  ---------------branch-reset----------- after
+         / ( a )  (?| x ( y ) z | (p (q) r) | (t) u (v) ) ( z ) /x
+         # 1            2         2  3        2     3     4
+
+       A backreference to a capture group uses the most recent value  that  is
+       set for the group. The following pattern matches "abcabc" or "defdef":
+
+         /(?|(abc)|(def))\1/
+
+       In  contrast, a subroutine call to a capture group always refers to the
+       first one in the pattern with the given number. The  following  pattern
+       matches "abcabc" or "defabc":
+
+         /(?|(abc)|(def))(?1)/
+
+       A relative reference such as (?-1) is no different: it is just a conve-
+       nient way of computing an absolute group number.
+
+       If a condition test for a group's having matched refers to a non-unique
+       number, the test is true if any group with that number has matched.
+
+       An  alternative approach to using this "branch reset" feature is to use
+       duplicate named groups, as described in the next section.
+
+
+NAMED CAPTURE GROUPS
+
+       Identifying capture groups by number is simple, but it can be very hard
+       to keep track of the numbers in complicated patterns.  Furthermore,  if
+       an  expression  is  modified, the numbers may change. To help with this
+       difficulty, PCRE2 supports the naming of capture groups.  This  feature
+       was  not  added to Perl until release 5.10. Python had the feature ear-
+       lier, and PCRE1 introduced it at release 4.0, using the Python  syntax.
+       PCRE2 supports both the Perl and the Python syntax.
+
+       In  PCRE2,  a  capture  group  can  be  named  in  one  of  three ways:
+       (?...) or (?'name'...) as in Perl, or (?P...) as in Python.
+       Names may be up to 128 code units long. When PCRE2_UTF is not set, they
+       may contain only ASCII alphanumeric  characters  and  underscores,  but
+       must start with a non-digit. When PCRE2_UTF is set, the syntax of group
+       names is extended to allow any Unicode letter or Unicode decimal digit.
+       In other words, group names must match one of these patterns:
+
+         ^[_A-Za-z][_A-Za-z0-9]*\z   when PCRE2_UTF is not set
+         ^[_\p{L}][_\p{L}\p{Nd}]*\z  when PCRE2_UTF is set
+
+       References  to  capture groups from other parts of the pattern, such as
+       backreferences, recursion, and conditions, can all be made by  name  as
+       well as by number.
+
+       Named capture groups are allocated numbers as well as names, exactly as
+       if  the  names were not present. In both PCRE2 and Perl, capture groups
+       are primarily identified by numbers; any names  are  just  aliases  for
+       these numbers. The PCRE2 API provides function calls for extracting the
+       complete  name-to-number  translation table from a compiled pattern, as
+       well as convenience functions for  extracting  captured  substrings  by
+       name.
+
+       Warning:  When  more than one capture group has the same number, as de-
+       scribed in the previous section, a name given to one of them applies to
+       all of them. Perl allows identically numbered groups to have  different
+       names.  Consider this pattern, where there are two capture groups, both
+       numbered 1:
+
+         (?|(?aa)|(?bb))
+
+       Perl  allows  this,  with  both  names AA and BB as aliases of group 1.
+       Thus, after a successful match, both names yield the same value (either
+       "aa" or "bb").
+
+       In an attempt to reduce confusion, PCRE2 does not allow the same  group
+       number to be associated with more than one name. The example above pro-
+       vokes  a  compile-time  error. However, there is still scope for confu-
+       sion. Consider this pattern:
+
+         (?|(?aa)|(bb))
+
+       Although the second group number 1 is not explicitly named, the name AA
+       is still an alias for any group 1. Whether the pattern matches "aa"  or
+       "bb", a reference by name to group AA yields the matched string.
+
+       By  default, a name must be unique within a pattern, except that dupli-
+       cate names are permitted for groups with the same number, for example:
+
+         (?|(?aa)|(?bb))
+
+       The duplicate name constraint can be disabled by setting the PCRE2_DUP-
+       NAMES option at compile time, or by the use of (?J) within the pattern,
+       as described in the section entitled "Internal Option Setting" above.
+
+       Duplicate names can be useful for patterns where only one  instance  of
+       the  named  capture group can match. Suppose you want to match the name
+       of a weekday, either as a 3-letter abbreviation or as  the  full  name,
+       and  in  both  cases you want to extract the abbreviation. This pattern
+       (ignoring the line breaks) does the job:
+
+         (?J)
+         (?Mon|Fri|Sun)(?:day)?|
+         (?Tue)(?:sday)?|
+         (?Wed)(?:nesday)?|
+         (?Thu)(?:rsday)?|
+         (?Sat)(?:urday)?
+
+       There are five capture groups, but only one is ever set after a  match.
+       The  convenience  functions for extracting the data by name returns the
+       substring for the first (and in this example, the only) group  of  that
+       name that matched. This saves searching to find which numbered group it
+       was.  (An  alternative  way of solving this problem is to use a "branch
+       reset" group, as described in the previous section.)
+
+       If you make a backreference to a non-unique named group from  elsewhere
+       in  the pattern, the groups to which the name refers are checked in the
+       order in which they appear in the overall pattern. The first  one  that
+       is  set  is  used  for the reference. For example, this pattern matches
+       both "foofoo" and "barbar" but not "foobar" or "barfoo":
+
+         (?J)(?:(?foo)|(?bar))\k
+
+
+       If you make a subroutine call to a non-unique named group, the one that
+       corresponds to the first occurrence of the name is used. In the absence
+       of duplicate numbers this is the one with the lowest number.
+
+       If you use a named reference in a condition test (see the section about
+       conditions below), either to check whether a capture group has matched,
+       or to check for recursion, all groups with the same name are tested. If
+       the condition is true for any one of them,  the  overall  condition  is
+       true.  This is the same behaviour as testing by number. For further de-
+       tails of the interfaces for handling  named  capture  groups,  see  the
+       pcre2api documentation.
+
+
+REPETITION
+
+       Repetition  is  specified  by  quantifiers, which may follow any one of
+       these items:
+
+         a literal data character
+         the dot metacharacter
+         the \C escape sequence
+         the \R escape sequence
+         the \X escape sequence
+         any escape sequence that matches a single character
+         a character class
+         a backreference
+         a parenthesized group (including lookaround assertions)
+         a subroutine call (recursive or otherwise)
+
+       If a quantifier does not follow a repeatable item, an error occurs. The
+       general repetition quantifier specifies a minimum and maximum number of
+       permitted matches by giving two numbers  in  curly  brackets  (braces),
+       separated  by  a  comma.  The  numbers must be less than 65536, and the
+       first must be less than or equal to the second. For example,
+
+         z{2,4}
+
+       matches "zz", "zzz", or "zzzz". A closing brace on its  own  is  not  a
+       special  character.  If  the second number is omitted, but the comma is
+       present, there is no upper limit; if the second number  and  the  comma
+       are  both omitted, the quantifier specifies an exact number of required
+       matches. Thus
+
+         [aeiou]{3,}
+
+       matches at least 3 successive vowels, but may match many more, whereas
+
+         \d{8}
+
+       matches exactly 8 digits. If the first number  is  omitted,  the  lower
+       limit is taken as zero; in this case the upper limit must be present.
+
+         X{,4} is interpreted as X{0,4}
+
+       This  is  a  change in behaviour that happened in Perl 5.34.0 and PCRE2
+       10.43. In earlier versions such a sequence was  not  interpreted  as  a
+       quantifier. Other regular expression engines may behave either way.
+
+       If  the characters that follow an opening brace do not match the syntax
+       of a quantifier, the brace is taken as a literal character. In particu-
+       lar, this means that {,} is a literal string of three characters.
+
+       Note that not every opening brace is potentially the start of a quanti-
+       fier because braces are used  in  other  items  such  as  \N{U+345}  or
+       \k{name}.
+
+       In UTF modes, quantifiers apply to characters rather than to individual
+       code  units. Thus, for example, \x{100}{2} matches two characters, each
+       of which is represented by a two-byte sequence in a UTF-8 string. Simi-
+       larly, \X{3} matches three Unicode extended grapheme clusters, each  of
+       which  may  be  several  code  units long (and they may be of different
+       lengths).
+
+       The quantifier {0} is permitted, causing the expression to behave as if
+       the previous item and the quantifier were not present. This may be use-
+       ful for capture groups that are referenced as  subroutines  from  else-
+       where  in the pattern (but see also the section entitled "Defining cap-
+       ture groups for use by reference only" below). Except for parenthesized
+       groups, items that have a {0} quantifier are omitted from the  compiled
+       pattern.
+
+       For  convenience, the three most common quantifiers have single-charac-
+       ter abbreviations:
+
+         *    is equivalent to {0,}
+         +    is equivalent to {1,}
+         ?    is equivalent to {0,1}
+
+       It is possible to construct infinite loops by following  a  group  that
+       can  match no characters with a quantifier that has no upper limit, for
+       example:
+
+         (a?)*
+
+       Earlier versions of Perl and PCRE1 used to give  an  error  at  compile
+       time for such patterns. However, because there are cases where this can
+       be useful, such patterns are now accepted, but whenever an iteration of
+       such  a group matches no characters, matching moves on to the next item
+       in the pattern instead of repeatedly matching  an  empty  string.  This
+       does  not  prevent  backtracking into any of the iterations if a subse-
+       quent item fails to match.
+
+       By default, quantifiers are "greedy", that is, they match  as  much  as
+       possible  (up  to the maximum number of permitted repetitions), without
+       causing the rest of the pattern to fail. The classic example  of  where
+       this gives problems is in trying to match comments in C programs. These
+       appear  between  /*  and  */ and within the comment, individual * and /
+       characters may appear. An attempt to match C comments by  applying  the
+       pattern
+
+         /\*.*\*/
+
+       to the string
+
+         /* first comment */  not comment  /* second comment */
+
+       fails,  because it matches the entire string owing to the greediness of
+       the .*  item. However, if a quantifier is followed by a question  mark,
+       it ceases to be greedy, and instead matches the minimum number of times
+       possible, so the pattern
+
+         /\*.*?\*/
+
+       does  the right thing with C comments. The meaning of the various quan-
+       tifiers is not otherwise changed, just the preferred number of matches.
+       Do not confuse this use of question mark with its use as  a  quantifier
+       in  its  own  right.   Because it has two uses, it can sometimes appear
+       doubled, as in
+
+         \d??\d
+
+       which matches one digit by preference, but can match two if that is the
+       only way the rest of the pattern matches.
+
+       If the PCRE2_UNGREEDY option is set (an option that is not available in
+       Perl), the quantifiers are not greedy by default, but  individual  ones
+       can  be  made  greedy  by following them with a question mark. In other
+       words, it inverts the default behaviour.
+
+       When a parenthesized group is quantified with a  minimum  repeat  count
+       that  is  greater  than 1 or with a limited maximum, more memory is re-
+       quired for the compiled pattern, in proportion to the size of the mini-
+       mum or maximum.
+
+       If a pattern starts with  .*  or  .{0,}  and  the  PCRE2_DOTALL  option
+       (equivalent  to  Perl's /s) is set, thus allowing the dot to match new-
+       lines, the pattern is implicitly  anchored,  because  whatever  follows
+       will  be  tried against every character position in the subject string,
+       so there is no point in retrying the overall match at any position  af-
+       ter  the  first. PCRE2 normally treats such a pattern as though it were
+       preceded by \A.
+
+       In cases where it is known that the subject  string  contains  no  new-
+       lines,  it  is worth setting PCRE2_DOTALL in order to obtain this opti-
+       mization, or alternatively, using ^ to indicate anchoring explicitly.
+
+       However, there are some cases where the optimization  cannot  be  used.
+       When  .*   is  inside  capturing  parentheses that are the subject of a
+       backreference elsewhere in the pattern, a match at the start  may  fail
+       where a later one succeeds. Consider, for example:
+
+         (.*)abc\1
+
+       If  the subject is "xyz123abc123" the match point is the fourth charac-
+       ter. For this reason, such a pattern is not implicitly anchored.
+
+       Another case where implicit anchoring is not applied is when the  lead-
+       ing  .* is inside an atomic group. Once again, a match at the start may
+       fail where a later one succeeds. Consider this pattern:
+
+         (?>.*?a)b
+
+       It matches "ab" in the subject "aab". The use of the backtracking  con-
+       trol  verbs  (*PRUNE)  and  (*SKIP) also disable this optimization, and
+       there is an option, PCRE2_NO_DOTSTAR_ANCHOR, to do so explicitly.
+
+       When a capture group is repeated, the value captured is  the  substring
+       that matched the final iteration. For example, after
+
+         (tweedle[dume]{3}\s*)+
+
+       has matched "tweedledum tweedledee" the value of the captured substring
+       is  "tweedledee". However, if there are nested capture groups, the cor-
+       responding captured values may have been set  in  previous  iterations.
+       For example, after
+
+         (a|(b))+
+
+       matches "aba" the value of the second captured substring is "b".
+
+
+ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS
+
+       With  both  maximizing ("greedy") and minimizing ("ungreedy" or "lazy")
+       repetition, failure of what follows normally causes the  repeated  item
+       to  be  re-evaluated to see if a different number of repeats allows the
+       rest of the pattern to match. Sometimes it is useful to  prevent  this,
+       either  to  change the nature of the match, or to cause it fail earlier
+       than it otherwise might, when the author of the pattern knows there  is
+       no point in carrying on.
+
+       Consider,  for  example, the pattern \d+foo when applied to the subject
+       line
+
+         123456bar
+
+       After matching all 6 digits and then failing to match "foo", the normal
+       action of the matcher is to try again with only 5 digits  matching  the
+       \d+  item,  and  then  with  4,  and  so on, before ultimately failing.
+       "Atomic grouping" (a term taken from Jeffrey  Friedl's  book)  provides
+       the means for specifying that once a group has matched, it is not to be
+       re-evaluated in this way.
+
+       If  we  use atomic grouping for the previous example, the matcher gives
+       up immediately on failing to match "foo" the first time.  The  notation
+       is a kind of special parenthesis, starting with (?> as in this example:
+
+         (?>\d+)foo
+
+       Perl  5.28  introduced an experimental alphabetic form starting with (*
+       which may be easier to remember:
+
+         (*atomic:\d+)foo
+
+       This kind of parenthesized group "locks up" the part of the pattern  it
+       contains once it has matched, and a failure further into the pattern is
+       prevented  from  backtracking into it. Backtracking past it to previous
+       items, however, works as normal.
+
+       An alternative description is that a group of this type matches exactly
+       the string of characters that an  identical  standalone  pattern  would
+       match, if anchored at the current point in the subject string.
+
+       Atomic  groups  are  not capture groups. Simple cases such as the above
+       example can be thought of as a  maximizing  repeat  that  must  swallow
+       everything  it can.  So, while both \d+ and \d+? are prepared to adjust
+       the number of digits they match in order to make the rest of  the  pat-
+       tern match, (?>\d+) can only match an entire sequence of digits.
+
+       Atomic  groups in general can of course contain arbitrarily complicated
+       expressions, and can be nested. However, when the contents of an atomic
+       group is just a single repeated item, as in the example above,  a  sim-
+       pler  notation, called a "possessive quantifier" can be used. This con-
+       sists of an additional + character following a quantifier.  Using  this
+       notation, the previous example can be rewritten as
+
+         \d++foo
+
+       Note that a possessive quantifier can be used with an entire group, for
+       example:
+
+         (abc|xyz){2,3}+
+
+       Possessive  quantifiers are always greedy; the setting of the PCRE2_UN-
+       GREEDY option is ignored. They are a convenient notation for  the  sim-
+       pler  forms  of  atomic  group.  However, there is no difference in the
+       meaning of a possessive quantifier and  the  equivalent  atomic  group,
+       though  there  may  be a performance difference; possessive quantifiers
+       should be slightly faster.
+
+       The possessive quantifier syntax is an extension to the Perl  5.8  syn-
+       tax.   Jeffrey  Friedl  originated the idea (and the name) in the first
+       edition of his book. Mike McCloskey liked it, so implemented it when he
+       built Sun's Java package, and PCRE1 copied it from there. It found  its
+       way into Perl at release 5.10.
+
+       PCRE2  has  an  optimization  that automatically "possessifies" certain
+       simple pattern constructs. For example, the sequence A+B is treated  as
+       A++B  because  there is no point in backtracking into a sequence of A's
+       when B must follow.  This feature can be disabled by the PCRE2_NO_AUTO-
+       POSSESS option, or starting the pattern with (*NO_AUTO_POSSESS).
+
+       When a pattern contains an unlimited repeat inside a group that can it-
+       self be repeated an unlimited number of times, the  use  of  an  atomic
+       group  is the only way to avoid some failing matches taking a very long
+       time indeed. The pattern
+
+         (\D+|<\d+>)*[!?]
+
+       matches an unlimited number of substrings that either consist  of  non-
+       digits,  or  digits  enclosed in <>, followed by either ! or ?. When it
+       matches, it runs quickly. However, if it is applied to
+
+         aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+
+       it takes a long time before reporting  failure.  This  is  because  the
+       string  can be divided between the internal \D+ repeat and the external
+       * repeat in a large number of ways, and all have to be tried. (The  ex-
+       ample uses [!?] rather than a single character at the end, because both
+       PCRE2 and Perl have an optimization that allows for fast failure when a
+       single  character is used. They remember the last single character that
+       is required for a match, and fail early if it is  not  present  in  the
+       string.)  If  the  pattern  is changed so that it uses an atomic group,
+       like this:
+
+         ((?>\D+)|<\d+>)*[!?]
+
+       sequences of non-digits cannot be broken, and failure happens quickly.
+
+
+BACKREFERENCES
+
+       Outside a character class, a backslash followed by a digit greater than
+       0 (and possibly further digits) is a backreference to a  capture  group
+       earlier (that is, to its left) in the pattern, provided there have been
+       that many previous capture groups.
+
+       However,  if the decimal number following the backslash is less than 8,
+       it is always taken as a backreference, and  causes  an  error  only  if
+       there  are not that many capture groups in the entire pattern. In other
+       words, the group that is referenced need not be to the left of the ref-
+       erence for numbers less than 8. A "forward backreference" of this  type
+       can make sense when a repetition is involved and the group to the right
+       has participated in an earlier iteration.
+
+       It  is  not  possible  to have a numerical "forward backreference" to a
+       group whose number is 8 or more using this syntax  because  a  sequence
+       such  as  \50  is  interpreted as a character defined in octal. See the
+       subsection entitled "Non-printing characters" above for further details
+       of the handling of digits following a backslash. Other forms  of  back-
+       referencing  do  not suffer from this restriction. In particular, there
+       is no problem when named capture groups are used (see below).
+
+       Another way of avoiding the ambiguity inherent in  the  use  of  digits
+       following  a  backslash  is  to use the \g escape sequence. This escape
+       must be followed by a signed or unsigned number, optionally enclosed in
+       braces. These examples are all identical:
+
+         (ring), \1
+         (ring), \g1
+         (ring), \g{1}
+
+       An unsigned number specifies an absolute reference without the  ambigu-
+       ity that is present in the older syntax. It is also useful when literal
+       digits  follow  the reference. A signed number is a relative reference.
+       Consider this example:
+
+         (abc(def)ghi)\g{-1}
+
+       The sequence \g{-1} is a reference to the capture group whose number is
+       one less than the number of the next group to be started,  so  in  this
+       example  (where the next group would be numbered 3) is it equivalent to
+       \2, and \g{-2} would be equivalent to \1. Note that if  this  construct
+       is  inside  a capture group, that group is included in the count, so in
+       this example \g{-2} also refers to group 1:
+
+         (A)(\g{-2}B)
+
+       The use of relative references can be helpful  in  long  patterns,  and
+       also  in  patterns  that are created by joining together fragments that
+       contain references within themselves.
+
+       The sequence \g{+1} is a reference to the next capture  group  that  is
+       started  after  this item, and \g{+2} refers to the one after that, and
+       so on. This kind of forward reference can be useful  in  patterns  that
+       repeat. Perl does not support the use of + in this way.
+
+       A  backreference  matches  whatever  actually most recently matched the
+       capture group in the current subject string, rather  than  anything  at
+       all that matches the group (see "Groups as subroutines" below for a way
+       of doing that). So the pattern
+
+         (sens|respons)e and \1ibility
+
+       matches  "sense and sensibility" and "response and responsibility", but
+       not "sense and responsibility". If caseful matching is in force at  the
+       time  of  the backreference, the case of letters is relevant. For exam-
+       ple,
+
+         ((?i)rah)\s+\1
+
+       matches "rah rah" and "RAH RAH", but not "RAH  rah",  even  though  the
+       original capture group is matched caselessly.
+
+       There  are  several  different  ways of writing backreferences to named
+       capture groups. The .NET syntax  is  \k{name},  the  Python  syntax  is
+       (?=name),  and the original Perl syntax is \k or \k'name'. All of
+       these are now supported by both Perl and  PCRE2.  Perl  5.10's  unified
+       backreference  syntax,  in  which  \g  can be used for both numeric and
+       named references, is also supported by PCRE2.   We  could  rewrite  the
+       above example in any of the following ways:
+
+         (?(?i)rah)\s+\k
+         (?'p1'(?i)rah)\s+\k{p1}
+         (?P(?i)rah)\s+(?P=p1)
+         (?(?i)rah)\s+\g{p1}
+
+       A  capture  group  that is referenced by name may appear in the pattern
+       before or after the reference.
+
+       There may be more than one backreference to the same group. If a  group
+       has  not actually been used in a particular match, backreferences to it
+       always fail by default. For example, the pattern
+
+         (a|(bc))\2
+
+       always fails if it starts to match "a" rather than  "bc".  However,  if
+       the PCRE2_MATCH_UNSET_BACKREF option is set at compile time, a backref-
+       erence to an unset value matches an empty string.
+
+       Because  there may be many capture groups in a pattern, all digits fol-
+       lowing a backslash are taken as part of a potential backreference  num-
+       ber.  If  the  pattern continues with a digit character, some delimiter
+       must be used to terminate the backreference. If the  PCRE2_EXTENDED  or
+       PCRE2_EXTENDED_MORE  option is set, this can be white space. Otherwise,
+       the \g{} syntax or an empty comment (see "Comments" below) can be used.
+
+   Recursive backreferences
+
+       A backreference that occurs inside the group to which it  refers  fails
+       when  the  group  is  first used, so, for example, (a\1) never matches.
+       However, such references can be useful inside repeated groups. For  ex-
+       ample, the pattern
+
+         (a|b\1)+
+
+       matches any number of "a"s and also "aba", "ababbaa" etc. At each iter-
+       ation of the group, the backreference matches the character string cor-
+       responding  to  the  previous iteration. In order for this to work, the
+       pattern must be such that the first iteration does not  need  to  match
+       the  backreference. This can be done using alternation, as in the exam-
+       ple above, or by a quantifier with a minimum of zero.
+
+       For versions of PCRE2 less than 10.25, backreferences of this type used
+       to cause the group that they reference  to  be  treated  as  an  atomic
+       group.   This restriction no longer applies, and backtracking into such
+       groups can occur as normal.
+
+
+ASSERTIONS
+
+       An assertion is a test on the characters  following  or  preceding  the
+       current matching point that does not consume any characters. The simple
+       assertions  coded  as  \b,  \B,  \A,  \G, \Z, \z, ^ and $ are described
+       above.
+
+       More complicated assertions are coded as  parenthesized  groups.  There
+       are  two  kinds:  those  that look ahead of the current position in the
+       subject string, and those that look behind it, and in each case an  as-
+       sertion  may  be  positive (must match for the assertion to be true) or
+       negative (must not match for the assertion to be  true).  An  assertion
+       group is matched in the normal way, and if it is true, matching contin-
+       ues  after it, but with the matching position in the subject string re-
+       set to what it was before the assertion was processed.
+
+       The Perl-compatible lookaround assertions are atomic. If  an  assertion
+       is  true, but there is a subsequent matching failure, there is no back-
+       tracking into the assertion. However, there are some cases  where  non-
+       atomic  assertions can be useful. PCRE2 has some support for these, de-
+       scribed in the section entitled "Non-atomic assertions" below, but they
+       are not Perl-compatible.
+
+       A lookaround assertion may appear as the  condition  in  a  conditional
+       group  (see  below). In this case, the result of matching the assertion
+       determines which branch of the condition is followed.
+
+       Assertion groups are not capture groups. If an assertion contains  cap-
+       ture  groups within it, these are counted for the purposes of numbering
+       the capture groups in the whole pattern. Within each branch of  an  as-
+       sertion,  locally  captured  substrings  may be referenced in the usual
+       way. For example, a sequence such as (.)\g{-1} can  be  used  to  check
+       that two adjacent characters are the same.
+
+       When  a  branch within an assertion fails to match, any substrings that
+       were captured are discarded (as happens with any  pattern  branch  that
+       fails  to  match).  A  negative  assertion  is  true  only when all its
+       branches fail to match; this means that no captured substrings are ever
+       retained after a successful negative assertion. When an assertion  con-
+       tains a matching branch, what happens depends on the type of assertion.
+
+       For  a  positive  assertion, internally captured substrings in the suc-
+       cessful branch are retained, and matching continues with the next  pat-
+       tern  item  after  the  assertion. For a negative assertion, a matching
+       branch means that the assertion is not true. If such  an  assertion  is
+       being  used as a condition in a conditional group (see below), captured
+       substrings are retained,  because  matching  continues  with  the  "no"
+       branch of the condition. For other failing negative assertions, control
+       passes to the previous backtracking point, thus discarding any captured
+       strings within the assertion.
+
+       Most  assertion groups may be repeated; though it makes no sense to as-
+       sert the same thing several times, the side effect of capturing in pos-
+       itive assertions may occasionally be useful. However, an assertion that
+       forms the condition for a conditional  group  may  not  be  quantified.
+       PCRE2  used  to restrict the repetition of assertions, but from release
+       10.35 the only restriction is that an unlimited maximum  repetition  is
+       changed  to  be one more than the minimum. For example, {3,} is treated
+       as {3,4}.
+
+   Alphabetic assertion names
+
+       Traditionally, symbolic sequences such as (?= and (?<= have  been  used
+       to  specify lookaround assertions. Perl 5.28 introduced some experimen-
+       tal alphabetic alternatives which might be easier to remember. They all
+       start with (* instead of (? and must be written using lower  case  let-
+       ters. PCRE2 supports the following synonyms:
+
+         (*positive_lookahead:  or (*pla: is the same as (?=
+         (*negative_lookahead:  or (*nla: is the same as (?!
+         (*positive_lookbehind: or (*plb: is the same as (?<=
+         (*negative_lookbehind: or (*nlb: is the same as (? .*? \b\1\b ){2}
+
+       For  a subject such as "word1 word2 word3 word2 word3 word4" the result
+       is "word3". How does it work? At the start, ^(?x) anchors  the  pattern
+       and sets the "x" option, which causes white space (introduced for read-
+       ability)  to  be  ignored. Inside the assertion, the greedy .* at first
+       consumes the entire string, but then has to backtrack until the rest of
+       the assertion can match a word, which is captured by group 1. In  other
+       words,  when  the  assertion first succeeds, it captures the right-most
+       word in the string.
+
+       The current matching point is then reset to the start of  the  subject,
+       and  the  rest  of  the pattern match checks for two occurrences of the
+       captured word, using an ungreedy .*? to scan from  the  left.  If  this
+       succeeds,  we are done, but if the last word in the string does not oc-
+       cur twice, this part of the pattern  fails.  If  a  traditional  atomic
+       lookahead  (?=  or (*pla: had been used, the assertion could not be re-
+       entered, and the whole match would fail. The pattern would succeed only
+       if the very last word in the subject was found twice.
+
+       Using a non-atomic lookahead, however, means that when  the  last  word
+       does  not  occur  twice  in the string, the lookahead can backtrack and
+       find the second-last word, and so on, until either the match  succeeds,
+       or all words have been tested.
+
+       Two conditions must be met for a non-atomic assertion to be useful: the
+       contents  of one or more capturing groups must change after a backtrack
+       into the assertion, and there must be  a  backreference  to  a  changed
+       group  later  in  the pattern. If this is not the case, the rest of the
+       pattern match fails exactly as before because nothing has  changed,  so
+       using a non-atomic assertion just wastes resources.
+
+       There  is one exception to backtracking into a non-atomic assertion. If
+       an (*ACCEPT) control verb is triggered, the assertion  succeeds  atomi-
+       cally.  That  is,  a subsequent match failure cannot backtrack into the
+       assertion.
+
+       Non-atomic assertions are not supported  by  the  alternative  matching
+       function pcre2_dfa_match(). They are supported by JIT, but only if they
+       do not contain any control verbs such as (*ACCEPT). (This may change in
+       future). Note that assertions that appear as conditions for conditional
+       groups (see below) must be atomic.
+
+
+SCRIPT RUNS
+
+       In  concept, a script run is a sequence of characters that are all from
+       the same Unicode script such as Latin or Greek. However,  because  some
+       scripts  are  commonly  used together, and because some diacritical and
+       other marks are used with multiple scripts,  it  is  not  that  simple.
+       There is a full description of the rules that PCRE2 uses in the section
+       entitled "Script Runs" in the pcre2unicode documentation.
+
+       If  part  of a pattern is enclosed between (*script_run: or (*sr: and a
+       closing parenthesis, it fails if the sequence  of  characters  that  it
+       matches  are not a script run. After a failure, normal backtracking oc-
+       curs. Script runs can be used to detect spoofing attacks using  charac-
+       ters  that  look  the  same, but are from different scripts. The string
+       "paypal.com" is an infamous example, where the letters could be a  mix-
+       ture of Latin and Cyrillic. This pattern ensures that the matched char-
+       acters in a sequence of non-spaces that follow white space are a script
+       run:
+
+         \s+(*sr:\S+)
+
+       To  be  sure  that  they are all from the Latin script (for example), a
+       lookahead can be used:
+
+         \s+(?=\p{Latin})(*sr:\S+)
+
+       This works as long as the first character is expected to be a character
+       in that script, and not (for example)  punctuation,  which  is  allowed
+       with  any script. If this is not the case, a more creative lookahead is
+       needed. For example, if digits, underscore, and dots are  permitted  at
+       the start:
+
+         \s+(?=[0-9_.]*\p{Latin})(*sr:\S+)
+
+
+       In  many  cases, backtracking into a script run pattern fragment is not
+       desirable. The script run can employ an atomic group to  prevent  this.
+       Because  this is a common requirement, a shorthand notation is provided
+       by (*atomic_script_run: or (*asr:
+
+         (*asr:...) is the same as (*sr:(?>...))
+
+       Note that the atomic group is inside the script run. Putting it outside
+       would not prevent backtracking into the script run pattern.
+
+       Support for script runs is not available if PCRE2 is  compiled  without
+       Unicode support. A compile-time error is given if any of the above con-
+       structs  is encountered. Script runs are not supported by the alternate
+       matching function, pcre2_dfa_match() because they use the  same  mecha-
+       nism as capturing parentheses.
+
+       Warning:  The  (*ACCEPT)  control  verb  (see below) should not be used
+       within a script run group, because it causes an immediate exit from the
+       group, bypassing the script run checking.
+
+
+CONDITIONAL GROUPS
+
+       It is possible to cause the matching process to obey a pattern fragment
+       conditionally or to choose between two alternative fragments, depending
+       on the result of an assertion, or whether a specific capture group  has
+       already been matched. The two possible forms of conditional group are:
+
+         (?(condition)yes-pattern)
+         (?(condition)yes-pattern|no-pattern)
+
+       If  the  condition is satisfied, the yes-pattern is used; otherwise the
+       no-pattern (if present) is used. An absent no-pattern is equivalent  to
+       an  empty string (it always matches). If there are more than two alter-
+       natives in the group, a compile-time error occurs. Each of the two  al-
+       ternatives may itself contain nested groups of any form, including con-
+       ditional  groups;  the  restriction to two alternatives applies only at
+       the level of the condition itself. This pattern fragment is an  example
+       where the alternatives are complex:
+
+         (?(1) (A|B|C) | (D | (?(2)E|F) | E) )
+
+
+       There are five kinds of condition: references to capture groups, refer-
+       ences  to  recursion,  two pseudo-conditions called DEFINE and VERSION,
+       and assertions.
+
+   Checking for a used capture group by number
+
+       If the text between the parentheses consists of a sequence  of  digits,
+       the  condition is true if a capture group of that number has previously
+       matched. If there is more than one capture group with the  same  number
+       (see  the earlier section about duplicate group numbers), the condition
+       is true if any of them have matched. An alternative notation, which  is
+       a PCRE2 extension, not supported by Perl, is to precede the digits with
+       a plus or minus sign. In this case, the group number is relative rather
+       than  absolute.  The most recently opened capture group (which could be
+       enclosing this condition) can be referenced by (?(-1),  the  next  most
+       recent by (?(-2), and so on. Inside loops it can also make sense to re-
+       fer  to  subsequent groups.  The next capture group to be opened can be
+       referenced as (?(+1), and so on. The value zero in any of  these  forms
+       is not used; it provokes a compile-time error.
+
+       Consider  the  following  pattern, which contains non-significant white
+       space to make it more readable (assume the PCRE2_EXTENDED  option)  and
+       to divide it into three parts for ease of discussion:
+
+         ( \( )?    [^()]+    (?(1) \) )
+
+       The  first  part  matches  an optional opening parenthesis, and if that
+       character is present, sets it as the first captured substring. The sec-
+       ond part matches one or more characters that are not  parentheses.  The
+       third  part  is a conditional group that tests whether or not the first
+       capture group matched. If it did, that is, if subject started  with  an
+       opening  parenthesis,  the condition is true, and so the yes-pattern is
+       executed and a closing parenthesis is required.  Otherwise,  since  no-
+       pattern is not present, the conditional group matches nothing. In other
+       words,  this  pattern matches a sequence of non-parentheses, optionally
+       enclosed in parentheses.
+
+       If you were embedding this pattern in a larger one,  you  could  use  a
+       relative reference:
+
+         ...other stuff... ( \( )?    [^()]+    (?(-1) \) ) ...
+
+       This  makes  the  fragment independent of the parentheses in the larger
+       pattern.
+
+   Checking for a used capture group by name
+
+       Perl uses the syntax (?()...) or (?('name')...)  to  test  for  a
+       used  capture group by name. For compatibility with earlier versions of
+       PCRE1, which had this facility before Perl, the syntax (?(name)...)  is
+       also  recognized.   Note, however, that undelimited names consisting of
+       the letter R followed by digits are ambiguous (see the  following  sec-
+       tion). Rewriting the above example to use a named group gives this:
+
+         (? \( )?    [^()]+    (?() \) )
+
+       If  the  name used in a condition of this kind is a duplicate, the test
+       is applied to all groups of the same name, and is true if  any  one  of
+       them has matched.
+
+   Checking for pattern recursion
+
+       "Recursion"  in  this sense refers to any subroutine-like call from one
+       part of the pattern to another, whether or not it  is  actually  recur-
+       sive.  See  the  sections  entitled "Recursive patterns" and "Groups as
+       subroutines" below for details of recursion and subroutine calls.
+
+       If a condition is the string (R), and there is no  capture  group  with
+       the  name R, the condition is true if matching is currently in a recur-
+       sion or subroutine call to the whole pattern or any capture  group.  If
+       digits  follow  the letter R, and there is no group with that name, the
+       condition is true if the most recent call is  into  a  group  with  the
+       given  number,  which must exist somewhere in the overall pattern. This
+       is a contrived example that is equivalent to a+b:
+
+         ((?(R1)a+|(?1)b))
+
+       However, in both cases, if there is a capture  group  with  a  matching
+       name,  the  condition tests for its being set, as described in the sec-
+       tion above, instead of testing for recursion. For example,  creating  a
+       group  with  the  name  R1  by adding (?) to the above pattern com-
+       pletely changes its meaning.
+
+       If a name preceded by ampersand follows the letter R, for example:
+
+         (?(R&name)...)
+
+       the condition is true if the most recent recursion is into a  group  of
+       that name (which must exist within the pattern).
+
+       This condition does not check the entire recursion stack. It tests only
+       the  current  level.  If the name used in a condition of this kind is a
+       duplicate, the test is applied to all groups of the same name,  and  is
+       true if any one of them is the most recent recursion.
+
+       At "top level", all these recursion test conditions are false.
+
+   Defining capture groups for use by reference only
+
+       If the condition is the string (DEFINE), the condition is always false,
+       even  if there is a group with the name DEFINE. In this case, there may
+       be only one alternative in the rest of the conditional group. It is al-
+       ways skipped if control reaches this point in the pattern; the idea  of
+       DEFINE  is that it can be used to define subroutines that can be refer-
+       enced from elsewhere. (The use of subroutines is described below.)  For
+       example,  a  pattern  to match an IPv4 address such as "192.168.23.245"
+       could be written like this (ignore white space and line breaks):
+
+         (?(DEFINE) (? 2[0-4]\d | 25[0-5] | 1\d\d | [1-9]?\d) )
+         \b (?&byte) (\.(?&byte)){3} \b
+
+       The first part of the pattern is a DEFINE group  inside  which  another
+       group  named "byte" is defined. This matches an individual component of
+       an IPv4 address (a number less than 256). When  matching  takes  place,
+       this  part  of  the pattern is skipped because DEFINE acts like a false
+       condition. The rest of the pattern uses references to the  named  group
+       to  match the four dot-separated components of an IPv4 address, insist-
+       ing on a word boundary at each end.
+
+   Checking the PCRE2 version
+
+       Programs that link with a PCRE2 library can check the version by  call-
+       ing  pcre2_config()  with  appropriate arguments. Users of applications
+       that do not have access to the underlying code cannot do this.  A  spe-
+       cial  "condition" called VERSION exists to allow such users to discover
+       which version of PCRE2 they are dealing with by using this condition to
+       match a string such as "yesno". VERSION must be followed either by  "="
+       or ">=" and a version number.  For example:
+
+         (?(VERSION>=10.4)yes|no)
+
+       This  pattern matches "yes" if the PCRE2 version is greater or equal to
+       10.4, or "no" otherwise. The fractional part of the version number  may
+       not contain more than two digits.
+
+   Assertion conditions
+
+       If  the  condition  is  not  in  any of the above formats, it must be a
+       parenthesized assertion. This may be a positive or  negative  lookahead
+       or  lookbehind  assertion. However, it must be a traditional atomic as-
+       sertion, not one of the non-atomic assertions.
+
+       Consider this pattern, again containing  non-significant  white  space,
+       and with the two alternatives on the second line:
+
+         (?(?=[^a-z]*[a-z])
+         \d{2}-[a-z]{3}-\d{2}  |  \d{2}-\d{2}-\d{2} )
+
+       The  condition  is  a  positive lookahead assertion that matches an op-
+       tional sequence of non-letters followed by a letter. In other words, it
+       tests for the presence of at least one letter in the subject. If a let-
+       ter is found, the subject is matched  against  the  first  alternative;
+       otherwise  it  is  matched  against  the  second.  This pattern matches
+       strings in one of the two forms dd-aaa-dd or dd-dd-dd,  where  aaa  are
+       letters and dd are digits.
+
+       When an assertion that is a condition contains capture groups, any cap-
+       turing  that  occurs  in  a matching branch is retained afterwards, for
+       both positive and negative assertions, because matching always  contin-
+       ues  after  the  assertion, whether it succeeds or fails. (Compare non-
+       conditional assertions, for which captures are retained only for  posi-
+       tive assertions that succeed.)
+
+
+COMMENTS
+
+       There are two ways of including comments in patterns that are processed
+       by  PCRE2.  In  both  cases,  the start of the comment must not be in a
+       character class, nor in the middle of any  other  sequence  of  related
+       characters  such  as (?: or a group name or number. The characters that
+       make up a comment play no part in the pattern matching.
+
+       The sequence (?# marks the start of a comment that continues up to  the
+       next  closing parenthesis. Nested parentheses are not permitted. If the
+       PCRE2_EXTENDED or PCRE2_EXTENDED_MORE option is  set,  an  unescaped  #
+       character  also  introduces  a comment, which in this case continues to
+       immediately after the next newline character or character  sequence  in
+       the pattern. Which characters are interpreted as newlines is controlled
+       by  an option passed to the compiling function or by a special sequence
+       at the start of the pattern, as described in the section entitled "New-
+       line conventions" above. Note that the end of this type of comment is a
+       literal newline sequence in the pattern; escape sequences  that  happen
+       to represent a newline do not count. For example, consider this pattern
+       when  PCRE2_EXTENDED is set, and the default newline convention (a sin-
+       gle linefeed character) is in force:
+
+         abc #comment \n still comment
+
+       On encountering the # character, pcre2_compile() skips  along,  looking
+       for  a newline in the pattern. The sequence \n is still literal at this
+       stage, so it does not terminate the comment. Only an  actual  character
+       with the code value 0x0a (the default newline) does so.
+
+
+RECURSIVE PATTERNS
+
+       Consider  the problem of matching a string in parentheses, allowing for
+       unlimited nested parentheses. Without the use of  recursion,  the  best
+       that  can  be  done  is  to use a pattern that matches up to some fixed
+       depth of nesting. It is not possible to  handle  an  arbitrary  nesting
+       depth.
+
+       For some time, Perl has provided a facility that allows regular expres-
+       sions  to recurse (amongst other things). It does this by interpolating
+       Perl code in the expression at run time, and the code can refer to  the
+       expression itself. A Perl pattern using code interpolation to solve the
+       parentheses problem can be created like this:
+
+         $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;
+
+       The (?p{...}) item interpolates Perl code at run time, and in this case
+       refers recursively to the pattern in which it appears.
+
+       Obviously,  PCRE2  cannot  support  the interpolation of Perl code. In-
+       stead, it supports special syntax for recursion of the entire  pattern,
+       and also for individual capture group recursion. After its introduction
+       in PCRE1 and Python, this kind of recursion was subsequently introduced
+       into Perl at release 5.10.
+
+       A  special  item  that consists of (? followed by a number greater than
+       zero and a closing parenthesis is a recursive subroutine  call  of  the
+       capture  group of the given number, provided that it occurs inside that
+       group. (If not, it is a non-recursive subroutine  call,  which  is  de-
+       scribed in the next section.) The special item (?R) or (?0) is a recur-
+       sive call of the entire regular expression.
+
+       This  PCRE2  pattern  solves the nested parentheses problem (assume the
+       PCRE2_EXTENDED option is set so that white space is ignored):
+
+         \( ( [^()]++ | (?R) )* \)
+
+       First it matches an opening parenthesis. Then it matches any number  of
+       substrings  which can either be a sequence of non-parentheses, or a re-
+       cursive match of the pattern itself (that is, a correctly parenthesized
+       substring).  Finally there is a closing parenthesis. Note the use of  a
+       possessive  quantifier  to  avoid  backtracking  into sequences of non-
+       parentheses.
+
+       If this were part of a larger pattern, you would not  want  to  recurse
+       the entire pattern, so instead you could use this:
+
+         ( \( ( [^()]++ | (?1) )* \) )
+
+       We  have  put the pattern into parentheses, and caused the recursion to
+       refer to them instead of the whole pattern.
+
+       In a larger pattern,  keeping  track  of  parenthesis  numbers  can  be
+       tricky.  This is made easier by the use of relative references. Instead
+       of (?1) in the pattern above you can write (?-2) to refer to the second
+       most recently opened parentheses  preceding  the  recursion.  In  other
+       words,  a  negative  number counts capturing parentheses leftwards from
+       the point at which it is encountered.
+
+       Be aware however, that if duplicate capture group numbers are  in  use,
+       relative  references  refer  to the earliest group with the appropriate
+       number. Consider, for example:
+
+         (?|(a)|(b)) (c) (?-2)
+
+       The first two capture groups (a) and (b) are both numbered 1, and group
+       (c) is number 2. When the reference (?-2) is  encountered,  the  second
+       most  recently opened parentheses has the number 1, but it is the first
+       such group (the (a) group) to which the recursion refers. This would be
+       the same if an absolute reference (?1) was used. In other words,  rela-
+       tive references are just a shorthand for computing a group number.
+
+       It  is  also possible to refer to subsequent capture groups, by writing
+       references such as (?+2). However, these cannot  be  recursive  because
+       the  reference  is not inside the parentheses that are referenced. They
+       are always non-recursive subroutine calls, as  described  in  the  next
+       section.
+
+       An  alternative  approach  is to use named parentheses. The Perl syntax
+       for this is (?&name); PCRE1's earlier syntax  (?P>name)  is  also  sup-
+       ported. We could rewrite the above example as follows:
+
+         (? \( ( [^()]++ | (?&pn) )* \) )
+
+       If there is more than one group with the same name, the earliest one is
+       used.
+
+       The example pattern that we have been looking at contains nested unlim-
+       ited  repeats,  and  so the use of a possessive quantifier for matching
+       strings of non-parentheses is important when applying  the  pattern  to
+       strings that do not match. For example, when this pattern is applied to
+
+         (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+
+       it  yields  "no  match" quickly. However, if a possessive quantifier is
+       not used, the match runs for a very long time indeed because there  are
+       so  many  different  ways the + and * repeats can carve up the subject,
+       and all have to be tested before failure can be reported.
+
+       At the end of a match, the values of capturing  parentheses  are  those
+       from  the outermost level. If you want to obtain intermediate values, a
+       callout function can be used (see below and the pcre2callout documenta-
+       tion). If the pattern above is matched against
+
+         (ab(cd)ef)
+
+       the value for the inner capturing parentheses  (numbered  2)  is  "ef",
+       which  is  the last value taken on at the top level. If a capture group
+       is not matched at the top level, its final  captured  value  is  unset,
+       even  if it was (temporarily) set at a deeper level during the matching
+       process.
+
+       Do not confuse the (?R) item with the condition (R),  which  tests  for
+       recursion.   Consider  this pattern, which matches text in angle brack-
+       ets, allowing for arbitrary nesting. Only digits are allowed in  nested
+       brackets  (that is, when recursing), whereas any characters are permit-
+       ted at the outer level.
+
+         < (?: (?(R) \d++  | [^<>]*+) | (?R)) * >
+
+       In this pattern, (?(R) is the start of a conditional  group,  with  two
+       different  alternatives  for the recursive and non-recursive cases. The
+       (?R) item is the actual recursive call.
+
+   Differences in recursion processing between PCRE2 and Perl
+
+       Some former differences between PCRE2 and Perl no longer exist.
+
+       Before release 10.30, recursion processing in PCRE2 differed from  Perl
+       in  that  a  recursive  subroutine call was always treated as an atomic
+       group. That is, once it had matched some of the subject string, it  was
+       never  re-entered,  even if it contained untried alternatives and there
+       was a subsequent matching failure. (Historical note:  PCRE  implemented
+       recursion before Perl did.)
+
+       Starting  with  release 10.30, recursive subroutine calls are no longer
+       treated as atomic. That is, they can be re-entered to try unused alter-
+       natives if there is a matching failure later in the  pattern.  This  is
+       now  compatible  with the way Perl works. If you want a subroutine call
+       to be atomic, you must explicitly enclose it in an atomic group.
+
+       Supporting backtracking into recursions simplifies certain types of re-
+       cursive pattern. For example, this pattern matches palindromic strings:
+
+         ^((.)(?1)\2|.?)$
+
+       The second branch in the group matches a single  central  character  in
+       the  palindrome  when there are an odd number of characters, or nothing
+       when there are an even number of characters, but in order  to  work  it
+       has  to  be  able  to  try the second case when the rest of the pattern
+       match fails. If you want to match typical palindromic phrases, the pat-
+       tern has to ignore all non-word characters,  which  can  be  done  like
+       this:
+
+         ^\W*+((.)\W*+(?1)\W*+\2|\W*+.?)\W*+$
+
+       If  run  with  the  PCRE2_CASELESS option, this pattern matches phrases
+       such as "A man, a plan, a canal: Panama!". Note the use of the  posses-
+       sive  quantifier  *+  to  avoid backtracking into sequences of non-word
+       characters. Without this, PCRE2 takes a great deal longer (ten times or
+       more) to match typical phrases, and Perl takes so long that  you  think
+       it has gone into a loop.
+
+       Another  way  in which PCRE2 and Perl used to differ in their recursion
+       processing is in the handling of captured  values.  Formerly  in  Perl,
+       when  a  group  was called recursively or as a subroutine (see the next
+       section), it had no access to any values that were captured outside the
+       recursion, whereas in PCRE2 these values can  be  referenced.  Consider
+       this pattern:
+
+         ^(.)(\1|a(?2))
+
+       This  pattern matches "bab". The first capturing parentheses match "b",
+       then in the second group, when the backreference \1 fails to match "b",
+       the second alternative matches "a" and then recurses. In the recursion,
+       \1 does now match "b" and so the whole match succeeds. This match  used
+       to fail in Perl, but in later versions (I tried 5.024) it now works.
+
+
+GROUPS AS SUBROUTINES
+
+       If  the syntax for a recursive group call (either by number or by name)
+       is used outside the parentheses to which it refers, it operates  a  bit
+       like  a  subroutine  in  a programming language. More accurately, PCRE2
+       treats the referenced group as an independent subpattern which it tries
+       to match at the current matching position. The called group may be  de-
+       fined  before  or  after the reference. A numbered reference can be ab-
+       solute or relative, as in these examples:
+
+         (...(absolute)...)...(?2)...
+         (...(relative)...)...(?-1)...
+         (...(?+1)...(relative)...
+
+       An earlier example pointed out that the pattern
+
+         (sens|respons)e and \1ibility
+
+       matches "sense and sensibility" and "response and responsibility",  but
+       not "sense and responsibility". If instead the pattern
+
+         (sens|respons)e and (?1)ibility
+
+       is  used, it does match "sense and responsibility" as well as the other
+       two strings. Another example is  given  in  the  discussion  of  DEFINE
+       above.
+
+       Like  recursions,  subroutine  calls  used to be treated as atomic, but
+       this changed at PCRE2 release 10.30, so  backtracking  into  subroutine
+       calls  can  now  occur. However, any capturing parentheses that are set
+       during the subroutine call revert to their previous values afterwards.
+
+       Processing options such as case-independence are fixed when a group  is
+       defined,  so  if  it  is  used  as a subroutine, such options cannot be
+       changed for different calls. For example, consider this pattern:
+
+         (abc)(?i:(?-1))
+
+       It matches "abcabc". It does not match "abcABC" because the  change  of
+       processing option does not affect the called group.
+
+       The  behaviour  of  backtracking control verbs in groups when called as
+       subroutines is described in the section entitled "Backtracking verbs in
+       subroutines" below.
+
+
+ONIGURUMA SUBROUTINE SYNTAX
+
+       For compatibility with Oniguruma, the non-Perl syntax \g followed by  a
+       name or a number enclosed either in angle brackets or single quotes, is
+       an alternative syntax for calling a group as a subroutine, possibly re-
+       cursively.  Here  are  two  of the examples used above, rewritten using
+       this syntax:
+
+         (? \( ( (?>[^()]+) | \g )* \) )
+         (sens|respons)e and \g'1'ibility
+
+       PCRE2 supports an extension to Oniguruma: if a number is preceded by  a
+       plus or a minus sign it is taken as a relative reference. For example:
+
+         (abc)(?i:\g<-1>)
+
+       Note  that \g{...} (Perl syntax) and \g<...> (Oniguruma syntax) are not
+       synonymous. The former is a backreference; the latter is  a  subroutine
+       call.
+
+
+CALLOUTS
+
+       Perl has a feature whereby using the sequence (?{...}) causes arbitrary
+       Perl  code to be obeyed in the middle of matching a regular expression.
+       This makes it possible, amongst other things, to extract different sub-
+       strings that match the same pair of parentheses when there is a repeti-
+       tion.
+
+       PCRE2 provides a similar feature, but of course it  cannot  obey  arbi-
+       trary  Perl  code. The feature is called "callout". The caller of PCRE2
+       provides an external function by putting its entry  point  in  a  match
+       context  using  the function pcre2_set_callout(), and then passing that
+       context to pcre2_match() or pcre2_dfa_match(). If no match  context  is
+       passed, or if the callout entry point is set to NULL, callouts are dis-
+       abled.
+
+       Within  a  regular expression, (?C) indicates a point at which the
+       external function is to be called. There  are  two  kinds  of  callout:
+       those  with a numerical argument and those with a string argument. (?C)
+       on its own with no argument is treated as (?C0). A  numerical  argument
+       allows  the  application  to  distinguish  between  different callouts.
+       String arguments were added for release 10.20 to make it  possible  for
+       script  languages that use PCRE2 to embed short scripts within patterns
+       in a similar way to Perl.
+
+       During matching, when PCRE2 reaches a callout point, the external func-
+       tion is called. It is provided with the number or  string  argument  of
+       the  callout, the position in the pattern, and one item of data that is
+       also set in the match block. The callout function may cause matching to
+       proceed, to backtrack, or to fail.
+
+       By default, PCRE2 implements a  number  of  optimizations  at  matching
+       time,  and  one  side-effect is that sometimes callouts are skipped. If
+       you need all possible callouts to happen, you need to set options  that
+       disable  the relevant optimizations. More details, including a complete
+       description of the programming interface to the callout  function,  are
+       given in the pcre2callout documentation.
+
+   Callouts with numerical arguments
+
+       If  you  just  want  to  have  a means of identifying different callout
+       points, put a number less than 256 after the  letter  C.  For  example,
+       this pattern has two callout points:
+
+         (?C1)abc(?C2)def
+
+       If  the PCRE2_AUTO_CALLOUT flag is passed to pcre2_compile(), numerical
+       callouts are automatically installed before each item in  the  pattern.
+       They  are all numbered 255. If there is a conditional group in the pat-
+       tern whose condition is an assertion, an additional callout is inserted
+       just before the condition. An explicit callout may also be set at  this
+       position, as in this example:
+
+         (?(?C9)(?=a)abc|def)
+
+       Note that this applies only to assertion conditions, not to other types
+       of condition.
+
+   Callouts with string arguments
+
+       A  delimited  string may be used instead of a number as a callout argu-
+       ment. The starting delimiter must be one of ` ' " ^ % #  $  {  and  the
+       ending delimiter is the same as the start, except for {, where the end-
+       ing  delimiter  is  }.  If  the  ending  delimiter is needed within the
+       string, it must be doubled. For example:
+
+         (?C'ab ''c'' d')xyz(?C{any text})pqr
+
+       The doubling is removed before the string  is  passed  to  the  callout
+       function.
+
+
+BACKTRACKING CONTROL
+
+       There  are  a  number  of  special "Backtracking Control Verbs" (to use
+       Perl's terminology) that modify the behaviour  of  backtracking  during
+       matching.  They are generally of the form (*VERB) or (*VERB:NAME). Some
+       verbs take either form, and may behave differently depending on whether
+       or not a name argument is present. The names are  not  required  to  be
+       unique within the pattern.
+
+       By  default,  for  compatibility  with  Perl, a name is any sequence of
+       characters that does not include a closing parenthesis. The name is not
+       processed in any way, and it is  not  possible  to  include  a  closing
+       parenthesis   in  the  name.   This  can  be  changed  by  setting  the
+       PCRE2_ALT_VERBNAMES option, but the result is no  longer  Perl-compati-
+       ble.
+
+       When  PCRE2_ALT_VERBNAMES  is  set,  backslash processing is applied to
+       verb names and only an unescaped  closing  parenthesis  terminates  the
+       name.  However, the only backslash items that are permitted are \Q, \E,
+       and sequences such as \x{100} that define character code points.  Char-
+       acter type escapes such as \d are faulted.
+
+       A closing parenthesis can be included in a name either as \) or between
+       \Q  and  \E. In addition to backslash processing, if the PCRE2_EXTENDED
+       or PCRE2_EXTENDED_MORE option is also set, unescaped whitespace in verb
+       names is skipped, and #-comments are recognized, exactly as in the rest
+       of the pattern.  PCRE2_EXTENDED and PCRE2_EXTENDED_MORE do  not  affect
+       verb names unless PCRE2_ALT_VERBNAMES is also set.
+
+       The  maximum  length of a name is 255 in the 8-bit library and 65535 in
+       the 16-bit and 32-bit libraries. If the name is empty, that is, if  the
+       closing  parenthesis immediately follows the colon, the effect is as if
+       the colon were not there. Any number of these verbs may occur in a pat-
+       tern. Except for (*ACCEPT), they may not be quantified.
+
+       Since these verbs are specifically related  to  backtracking,  most  of
+       them  can be used only when the pattern is to be matched using the tra-
+       ditional matching function, because that uses a backtracking algorithm.
+       With the exception of (*FAIL), which behaves like  a  failing  negative
+       assertion, the backtracking control verbs cause an error if encountered
+       by the DFA matching function.
+
+       The  behaviour  of  these  verbs in repeated groups, assertions, and in
+       capture groups called as subroutines (whether or  not  recursively)  is
+       documented below.
+
+   Optimizations that affect backtracking verbs
+
+       PCRE2 contains some optimizations that are used to speed up matching by
+       running some checks at the start of each match attempt. For example, it
+       may  know  the minimum length of matching subject, or that a particular
+       character must be present. When one of these optimizations bypasses the
+       running of a match,  any  included  backtracking  verbs  will  not,  of
+       course, be processed. You can suppress the start-of-match optimizations
+       by  setting  the PCRE2_NO_START_OPTIMIZE option when calling pcre2_com-
+       pile(), or by starting the pattern with (*NO_START_OPT). There is  more
+       discussion of this option in the section entitled "Compiling a pattern"
+       in the pcre2api documentation.
+
+       Experiments  with  Perl  suggest that it too has similar optimizations,
+       and like PCRE2, turning them off can change the result of a match.
+
+   Verbs that act immediately
+
+       The following verbs act as soon as they are encountered.
+
+          (*ACCEPT) or (*ACCEPT:NAME)
+
+       This verb causes the match to end successfully, skipping the  remainder
+       of  the  pattern.  However,  when  it is inside a capture group that is
+       called as a subroutine, only that group is ended successfully. Matching
+       then continues at the outer level. If (*ACCEPT) in triggered in a posi-
+       tive assertion, the assertion succeeds; in a  negative  assertion,  the
+       assertion fails.
+
+       If  (*ACCEPT)  is inside capturing parentheses, the data so far is cap-
+       tured. For example:
+
+         A((?:A|B(*ACCEPT)|C)D)
+
+       This matches "AB", "AAD", or "ACD"; when it matches "AB", "B"  is  cap-
+       tured by the outer parentheses.
+
+       (*ACCEPT)  is  the only backtracking verb that is allowed to be quanti-
+       fied because an ungreedy quantification with a  minimum  of  zero  acts
+       only when a backtrack happens. Consider, for example,
+
+         (A(*ACCEPT)??B)C
+
+       where  A,  B, and C may be complex expressions. After matching "A", the
+       matcher processes "BC"; if that fails, causing a  backtrack,  (*ACCEPT)
+       is  triggered  and the match succeeds. In both cases, all but C is cap-
+       tured. Whereas (*COMMIT) (see below) means "fail on backtrack",  a  re-
+       peated (*ACCEPT) of this type means "succeed on backtrack".
+
+       Warning:  (*ACCEPT)  should  not be used within a script run group, be-
+       cause it causes an immediate exit from the group, bypassing the  script
+       run checking.
+
+         (*FAIL) or (*FAIL:NAME)
+
+       This  verb causes a matching failure, forcing backtracking to occur. It
+       may be abbreviated to (*F). It is equivalent  to  (?!)  but  easier  to
+       read. The Perl documentation notes that it is probably useful only when
+       combined with (?{}) or (??{}). Those are, of course, Perl features that
+       are  not  present  in PCRE2. The nearest equivalent is the callout fea-
+       ture, as for example in this pattern:
+
+         a+(?C)(*FAIL)
+
+       A match with the string "aaaa" always fails, but the callout  is  taken
+       before each backtrack happens (in this example, 10 times).
+
+       (*ACCEPT:NAME)  and  (*FAIL:NAME)  behave the same as (*MARK:NAME)(*AC-
+       CEPT) and (*MARK:NAME)(*FAIL), respectively,  that  is,  a  (*MARK)  is
+       recorded just before the verb acts.
+
+   Recording which path was taken
+
+       There  is  one  verb whose main purpose is to track how a match was ar-
+       rived at, though it also has a secondary use in  conjunction  with  ad-
+       vancing the match starting point (see (*SKIP) below).
+
+         (*MARK:NAME) or (*:NAME)
+
+       A  name is always required with this verb. For all the other backtrack-
+       ing control verbs, a NAME argument is optional.
+
+       When a match succeeds, the name of the last-encountered  mark  name  on
+       the matching path is passed back to the caller as described in the sec-
+       tion entitled "Other information about the match" in the pcre2api docu-
+       mentation.  This  applies  to all instances of (*MARK) and other verbs,
+       including those inside assertions and atomic groups. However, there are
+       differences in those cases when (*MARK) is  used  in  conjunction  with
+       (*SKIP) as described below.
+
+       The  mark name that was last encountered on the matching path is passed
+       back. A verb without a NAME argument is ignored for this purpose.  Here
+       is  an  example of pcre2test output, where the "mark" modifier requests
+       the retrieval and outputting of (*MARK) data:
+
+           re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+         data> XY
+          0: XY
+         MK: A
+         XZ
+          0: XZ
+         MK: B
+
+       The (*MARK) name is tagged with "MK:" in this output, and in this exam-
+       ple it indicates which of the two alternatives matched. This is a  more
+       efficient  way of obtaining this information than putting each alterna-
+       tive in its own capturing parentheses.
+
+       If a verb with a name is encountered in a positive  assertion  that  is
+       true,  the  name  is recorded and passed back if it is the last-encoun-
+       tered. This does not happen for negative assertions or failing positive
+       assertions.
+
+       After a partial match or a failed match, the last encountered  name  in
+       the entire match process is returned. For example:
+
+           re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+         data> XP
+         No match, mark = B
+
+       Note  that  in  this  unanchored  example the mark is retained from the
+       match attempt that started at the letter "X" in the subject. Subsequent
+       match attempts starting at "P" and then with an empty string do not get
+       as far as the (*MARK) item, but nevertheless do not reset it.
+
+       If you are interested in  (*MARK)  values  after  failed  matches,  you
+       should  probably  set the PCRE2_NO_START_OPTIMIZE option (see above) to
+       ensure that the match is always attempted.
+
+   Verbs that act after backtracking
+
+       The following verbs do nothing when they are encountered. Matching con-
+       tinues with what follows, but if there is a subsequent  match  failure,
+       causing  a  backtrack  to the verb, a failure is forced. That is, back-
+       tracking cannot pass to the left of the  verb.  However,  when  one  of
+       these verbs appears inside an atomic group or in a lookaround assertion
+       that  is  true,  its effect is confined to that group, because once the
+       group has been matched, there is never any backtracking into it.  Back-
+       tracking from beyond an assertion or an atomic group ignores the entire
+       group, and seeks a preceding backtracking point.
+
+       These  verbs  differ  in exactly what kind of failure occurs when back-
+       tracking reaches them. The behaviour described below  is  what  happens
+       when  the  verb is not in a subroutine or an assertion. Subsequent sec-
+       tions cover these special cases.
+
+         (*COMMIT) or (*COMMIT:NAME)
+
+       This verb causes the whole match to fail outright if there is  a  later
+       matching failure that causes backtracking to reach it. Even if the pat-
+       tern  is  unanchored,  no further attempts to find a match by advancing
+       the starting point take place. If (*COMMIT) is  the  only  backtracking
+       verb that is encountered, once it has been passed pcre2_match() is com-
+       mitted to finding a match at the current starting point, or not at all.
+       For example:
+
+         a+(*COMMIT)b
+
+       This  matches  "xxaab" but not "aacaab". It can be thought of as a kind
+       of dynamic anchor, or "I've started, so I must finish."
+
+       The behaviour of (*COMMIT:NAME) is not the same  as  (*MARK:NAME)(*COM-
+       MIT).  It is like (*MARK:NAME) in that the name is remembered for pass-
+       ing back to the caller. However, (*SKIP:NAME) searches only  for  names
+       that are set with (*MARK), ignoring those set by any of the other back-
+       tracking verbs.
+
+       If  there  is more than one backtracking verb in a pattern, a different
+       one that follows (*COMMIT) may be triggered first,  so  merely  passing
+       (*COMMIT) during a match does not always guarantee that a match must be
+       at this starting point.
+
+       Note that (*COMMIT) at the start of a pattern is not the same as an an-
+       chor,  unless  PCRE2's  start-of-match optimizations are turned off, as
+       shown in this output from pcre2test:
+
+           re> /(*COMMIT)abc/
+         data> xyzabc
+          0: abc
+         data>
+         re> /(*COMMIT)abc/no_start_optimize
+         data> xyzabc
+         No match
+
+       For the first pattern, PCRE2 knows that any match must start with  "a",
+       so  the optimization skips along the subject to "a" before applying the
+       pattern to the first set of data. The match attempt then succeeds.  The
+       second  pattern disables the optimization that skips along to the first
+       character. The pattern is now applied  starting  at  "x",  and  so  the
+       (*COMMIT)  causes  the  match to fail without trying any other starting
+       points.
+
+         (*PRUNE) or (*PRUNE:NAME)
+
+       This verb causes the match to fail at the current starting position  in
+       the subject if there is a later matching failure that causes backtrack-
+       ing  to  reach it. If the pattern is unanchored, the normal "bumpalong"
+       advance to the next starting character then happens.  Backtracking  can
+       occur  as  usual to the left of (*PRUNE), before it is reached, or when
+       matching to the right of (*PRUNE), but if there  is  no  match  to  the
+       right,  backtracking cannot cross (*PRUNE). In simple cases, the use of
+       (*PRUNE) is just an alternative to an atomic group or possessive  quan-
+       tifier, but there are some uses of (*PRUNE) that cannot be expressed in
+       any  other  way. In an anchored pattern (*PRUNE) has the same effect as
+       (*COMMIT).
+
+       The behaviour of (*PRUNE:NAME) is not the same as (*MARK:NAME)(*PRUNE).
+       It is like (*MARK:NAME) in that the name is remembered for passing back
+       to the caller. However, (*SKIP:NAME) searches only for names  set  with
+       (*MARK), ignoring those set by other backtracking verbs.
+
+         (*SKIP)
+
+       This  verb, when given without a name, is like (*PRUNE), except that if
+       the pattern is unanchored, the "bumpalong" advance is not to  the  next
+       character, but to the position in the subject where (*SKIP) was encoun-
+       tered.  (*SKIP)  signifies that whatever text was matched leading up to
+       it cannot be part of a successful match if there is a  later  mismatch.
+       Consider:
+
+         a+(*SKIP)b
+
+       If  the  subject  is  "aaaac...",  after  the first match attempt fails
+       (starting at the first character in the  string),  the  starting  point
+       skips on to start the next attempt at "c". Note that a possessive quan-
+       tifier does not have the same effect as this example; although it would
+       suppress  backtracking  during  the first match attempt, the second at-
+       tempt would start at the second character instead  of  skipping  on  to
+       "c".
+
+       If  (*SKIP) is used to specify a new starting position that is the same
+       as the starting position of the current match, or (by  being  inside  a
+       lookbehind)  earlier, the position specified by (*SKIP) is ignored, and
+       instead the normal "bumpalong" occurs.
+
+         (*SKIP:NAME)
+
+       When (*SKIP) has an associated name, its behaviour  is  modified.  When
+       such  a  (*SKIP) is triggered, the previous path through the pattern is
+       searched for the most recent (*MARK) that has the same name. If one  is
+       found,  the  "bumpalong" advance is to the subject position that corre-
+       sponds to that (*MARK) instead of to where (*SKIP) was encountered.  If
+       no (*MARK) with a matching name is found, the (*SKIP) is ignored.
+
+       The  search  for a (*MARK) name uses the normal backtracking mechanism,
+       which means that it does not  see  (*MARK)  settings  that  are  inside
+       atomic groups or assertions, because they are never re-entered by back-
+       tracking. Compare the following pcre2test examples:
+
+           re> /a(?>(*MARK:X))(*SKIP:X)(*F)|(.)/
+         data: abc
+          0: a
+          1: a
+         data:
+           re> /a(?:(*MARK:X))(*SKIP:X)(*F)|(.)/
+         data: abc
+          0: b
+          1: b
+
+       In  the first example, the (*MARK) setting is in an atomic group, so it
+       is not seen when (*SKIP:X) triggers, causing the (*SKIP) to be ignored.
+       This allows the second branch of the pattern to be tried at  the  first
+       character  position.  In the second example, the (*MARK) setting is not
+       in an atomic group. This allows (*SKIP:X) to find the (*MARK)  when  it
+       backtracks, and this causes a new matching attempt to start at the sec-
+       ond  character.  This  time, the (*MARK) is never seen because "a" does
+       not match "b", so the matcher immediately jumps to the second branch of
+       the pattern.
+
+       Note that (*SKIP:NAME) searches only for names set by (*MARK:NAME).  It
+       ignores names that are set by other backtracking verbs.
+
+         (*THEN) or (*THEN:NAME)
+
+       This  verb  causes  a skip to the next innermost alternative when back-
+       tracking reaches it. That  is,  it  cancels  any  further  backtracking
+       within  the  current  alternative.  Its name comes from the observation
+       that it can be used for a pattern-based if-then-else block:
+
+         ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+
+       If the COND1 pattern matches, FOO is tried (and possibly further  items
+       after  the  end  of the group if FOO succeeds); on failure, the matcher
+       skips to the second alternative and tries COND2,  without  backtracking
+       into  COND1.  If that succeeds and BAR fails, COND3 is tried. If subse-
+       quently BAZ fails, there are no more alternatives, so there is a  back-
+       track  to  whatever came before the entire group. If (*THEN) is not in-
+       side an alternation, it acts like (*PRUNE).
+
+       The behaviour of (*THEN:NAME) is not the same  as  (*MARK:NAME)(*THEN).
+       It is like (*MARK:NAME) in that the name is remembered for passing back
+       to  the  caller. However, (*SKIP:NAME) searches only for names set with
+       (*MARK), ignoring those set by other backtracking verbs.
+
+       A group that does not contain a | character is just a part of  the  en-
+       closing  alternative;  it is not a nested alternation with only one al-
+       ternative. The effect of (*THEN) extends beyond such a group to the en-
+       closing alternative.  Consider this pattern, where A, B, etc. are  com-
+       plex  pattern  fragments  that  do not contain any | characters at this
+       level:
+
+         A (B(*THEN)C) | D
+
+       If A and B are matched, but there is a failure in C, matching does  not
+       backtrack into A; instead it moves to the next alternative, that is, D.
+       However,  if  the  group containing (*THEN) is given an alternative, it
+       behaves differently:
+
+         A (B(*THEN)C | (*FAIL)) | D
+
+       The effect of (*THEN) is now confined to the inner group. After a fail-
+       ure in C, matching moves to (*FAIL), which causes the  whole  group  to
+       fail  because  there  are  no  more  alternatives to try. In this case,
+       matching does backtrack into A.
+
+       Note that a conditional group is not considered as having two  alterna-
+       tives,  because  only one is ever used. In other words, the | character
+       in a conditional group has a different meaning. Ignoring  white  space,
+       consider:
+
+         ^.*? (?(?=a) a | b(*THEN)c )
+
+       If the subject is "ba", this pattern does not match. Because .*? is un-
+       greedy,  it initially matches zero characters. The condition (?=a) then
+       fails, the character "b" is matched, but "c" is  not.  At  this  point,
+       matching  does  not  backtrack to .*? as might perhaps be expected from
+       the presence of the | character. The conditional group is part  of  the
+       single  alternative  that comprises the whole pattern, and so the match
+       fails. (If there was a backtrack into .*?, allowing it  to  match  "b",
+       the match would succeed.)
+
+       The  verbs just described provide four different "strengths" of control
+       when subsequent matching fails. (*THEN) is the weakest, carrying on the
+       match at the next alternative. (*PRUNE) comes next, failing  the  match
+       at  the  current starting position, but allowing an advance to the next
+       character (for an unanchored pattern). (*SKIP) is similar, except  that
+       the advance may be more than one character. (*COMMIT) is the strongest,
+       causing the entire match to fail.
+
+   More than one backtracking verb
+
+       If  more  than  one  backtracking verb is present in a pattern, the one
+       that is backtracked onto first acts. For example,  consider  this  pat-
+       tern, where A, B, etc. are complex pattern fragments:
+
+         (A(*COMMIT)B(*THEN)C|ABD)
+
+       If  A matches but B fails, the backtrack to (*COMMIT) causes the entire
+       match to fail. However, if A and B match, but C fails, the backtrack to
+       (*THEN) causes the next alternative (ABD) to be tried.  This  behaviour
+       is  consistent,  but is not always the same as Perl's. It means that if
+       two or more backtracking verbs appear in succession, all but  the  last
+       of them has no effect. Consider this example:
+
+         ...(*COMMIT)(*PRUNE)...
+
+       If there is a matching failure to the right, backtracking onto (*PRUNE)
+       causes  it to be triggered, and its action is taken. There can never be
+       a backtrack onto (*COMMIT).
+
+   Backtracking verbs in repeated groups
+
+       PCRE2 sometimes differs from Perl in its handling of backtracking verbs
+       in repeated groups. For example, consider:
+
+         /(a(*COMMIT)b)+ac/
+
+       If the subject is "abac", Perl matches  unless  its  optimizations  are
+       disabled,  but  PCRE2  always fails because the (*COMMIT) in the second
+       repeat of the group acts.
+
+   Backtracking verbs in assertions
+
+       (*FAIL) in any assertion has its normal effect: it forces an  immediate
+       backtrack.  The  behaviour  of  the other backtracking verbs depends on
+       whether or not the assertion is standalone or acting as  the  condition
+       in a conditional group.
+
+       (*ACCEPT)  in  a  standalone positive assertion causes the assertion to
+       succeed without any further processing; captured  strings  and  a  mark
+       name  (if  set) are retained. In a standalone negative assertion, (*AC-
+       CEPT) causes the assertion to fail without any further processing; cap-
+       tured substrings and any mark name are discarded.
+
+       If the assertion is a condition, (*ACCEPT) causes the condition  to  be
+       true  for  a  positive assertion and false for a negative one; captured
+       substrings are retained in both cases.
+
+       The remaining verbs act only when a later failure causes a backtrack to
+       reach them. This means that, for the Perl-compatible assertions,  their
+       effect is confined to the assertion, because Perl lookaround assertions
+       are atomic. A backtrack that occurs after such an assertion is complete
+       does  not  jump  back  into  the  assertion.  Note in particular that a
+       (*MARK) name that is set in an assertion is not "seen" by  an  instance
+       of (*SKIP:NAME) later in the pattern.
+
+       PCRE2  now supports non-atomic positive assertions, as described in the
+       section entitled "Non-atomic assertions" above. These  assertions  must
+       be  standalone  (not used as conditions). They are not Perl-compatible.
+       For these assertions, a later backtrack does jump back into the  asser-
+       tion,  and  therefore verbs such as (*COMMIT) can be triggered by back-
+       tracks from later in the pattern.
+
+       The effect of (*THEN) is not allowed to escape beyond an assertion.  If
+       there  are no more branches to try, (*THEN) causes a positive assertion
+       to be false, and a negative assertion to be true.
+
+       The other backtracking verbs are not treated specially if  they  appear
+       in  a  standalone  positive assertion. In a conditional positive asser-
+       tion, backtracking (from within the assertion) into (*COMMIT), (*SKIP),
+       or (*PRUNE) causes the condition to be false. However, for both  stand-
+       alone and conditional negative assertions, backtracking into (*COMMIT),
+       (*SKIP), or (*PRUNE) causes the assertion to be true, without consider-
+       ing any further alternative branches.
+
+   Backtracking verbs in subroutines
+
+       These behaviours occur whether or not the group is called recursively.
+
+       (*ACCEPT) in a group called as a subroutine causes the subroutine match
+       to  succeed without any further processing. Matching then continues af-
+       ter the subroutine call. Perl documents this behaviour.  Perl's  treat-
+       ment of the other verbs in subroutines is different in some cases.
+
+       (*FAIL)  in  a  group  called as a subroutine has its normal effect: it
+       forces an immediate backtrack.
+
+       (*COMMIT), (*SKIP), and (*PRUNE) cause the  subroutine  match  to  fail
+       when  triggered  by being backtracked to in a group called as a subrou-
+       tine. There is then a backtrack at the outer level.
+
+       (*THEN), when triggered, skips to the next alternative in the innermost
+       enclosing group that has alternatives (its normal behaviour).  However,
+       if there is no such group within the subroutine's group, the subroutine
+       match fails and there is a backtrack at the outer level.

+PCRE2 PERFORMANCE
+
+       Two  aspects  of performance are discussed below: memory usage and pro-
+       cessing time. The way you express your pattern as a regular  expression
+       can affect both of them.
+
+
+COMPILED PATTERN MEMORY USAGE
+
+       Patterns are compiled by PCRE2 into a reasonably efficient interpretive
+       code,  so  that most simple patterns do not use much memory for storing
+       the compiled version. However, there is one case where the memory usage
+       of a compiled pattern can be unexpectedly  large.  If  a  parenthesized
+       group  has  a quantifier with a minimum greater than 1 and/or a limited
+       maximum, the whole group is repeated in the compiled code. For example,
+       the pattern
+
+         (abc|def){2,4}
+
+       is compiled as if it were
+
+         (abc|def)(abc|def)((abc|def)(abc|def)?)?
+
+       (Technical aside: It is done this way so that backtrack  points  within
+       each of the repetitions can be independently maintained.)
+
+       For  regular expressions whose quantifiers use only small numbers, this
+       is not usually a problem. However, if the numbers are large,  and  par-
+       ticularly  if  such repetitions are nested, the memory usage can become
+       an embarrassment. For example, the very simple pattern
+
+         ((ab){1,1000}c){1,3}
+
+       uses over 50KiB when compiled using the 8-bit library.  When  PCRE2  is
+       compiled  with its default internal pointer size of two bytes, the size
+       limit on a compiled pattern is 65535 code units in the 8-bit and 16-bit
+       libraries, and this is reached with the above pattern if the outer rep-
+       etition is increased from 3 to 4. PCRE2 can be compiled to  use  larger
+       internal  pointers  and thus handle larger compiled patterns, but it is
+       better to try to rewrite your pattern to use less memory if you can.
+
+       One way of reducing the memory usage for such patterns is to  make  use
+       of PCRE2's "subroutine" facility. Re-writing the above pattern as
+
+         ((ab)(?2){0,999}c)(?1){0,2}
+
+       reduces  the memory requirements to around 16KiB, and indeed it remains
+       under 20KiB even with the outer repetition increased to  100.  However,
+       this kind of pattern is not always exactly equivalent, because any cap-
+       tures  within  subroutine calls are lost when the subroutine completes.
+       If this is not a problem, this kind of  rewriting  will  allow  you  to
+       process  patterns that PCRE2 cannot otherwise handle. The matching per-
+       formance of the two different versions of the pattern are  roughly  the
+       same.  (This applies from release 10.30 - things were different in ear-
+       lier releases.)
+
+
+STACK AND HEAP USAGE AT RUN TIME
+
+       From release 10.30, the interpretive (non-JIT) version of pcre2_match()
+       uses very little system stack at run time. In earlier  releases  recur-
+       sive  function  calls  could  use a great deal of stack, and this could
+       cause problems, but this usage has been eliminated. Backtracking  posi-
+       tions  are now explicitly remembered in memory frames controlled by the
+       code.
+
+       The size of each frame depends on the size of pointer variables and the
+       number of capturing parenthesized groups in the pattern being  matched.
+       On a 64-bit system the frame size for a pattern with no captures is 128
+       bytes. For each capturing group the size increases by 16 bytes.
+
+       Until  release  10.41,  an initial 20KiB frames vector was allocated on
+       the system stack, but this still caused some  issues  for  multi-thread
+       applications  where  each  thread  has a very small stack. From release
+       10.41 backtracking memory frames are always held  in  heap  memory.  An
+       initial heap allocation is obtained the first time any match data block
+       is  passed  to  pcre2_match().  This  is remembered with the match data
+       block and re-used if that block is used for another match. It is  freed
+       when the match data block itself is freed.
+
+       The  size  of the initial block is the larger of 20KiB or ten times the
+       pattern's frame size, unless the heap limit is less than this, in which
+       case the heap limit is used. If the initial  block  proves  to  be  too
+       small during matching, it is replaced by a larger block, subject to the
+       heap  limit.  The  heap limit is checked only when a new block is to be
+       allocated. Reducing the heap limit between calls to pcre2_match()  with
+       the same match data block does not affect the saved block.
+
+       In  contrast  to  pcre2_match(),  pcre2_dfa_match()  does use recursive
+       function calls, but only for processing atomic groups,  lookaround  as-
+       sertions, and recursion within the pattern. The original version of the
+       code  used  to  allocate  quite large internal workspace vectors on the
+       stack, which caused some problems for  some  patterns  in  environments
+       with  small  stacks.  From release 10.32 the code for pcre2_dfa_match()
+       has been re-factored to use heap memory  when  necessary  for  internal
+       workspace  when  recursing,  though  recursive function calls are still
+       used.
+
+       The "match depth" parameter can be used to limit the depth of  function
+       recursion,  and  the  "match  heap"  parameter  to limit heap memory in
+       pcre2_dfa_match().
+
+
+PROCESSING TIME
+
+       Certain items in regular expression patterns are processed  more  effi-
+       ciently than others. It is more efficient to use a character class like
+       [aeiou]   than   a   set   of  single-character  alternatives  such  as
+       (a|e|i|o|u). In general, the simplest construction  that  provides  the
+       required behaviour is usually the most efficient. Jeffrey Friedl's book
+       contains  a  lot  of useful general discussion about optimizing regular
+       expressions for efficient performance. This document contains a few ob-
+       servations about PCRE2.
+
+       Using Unicode character properties (the \p,  \P,  and  \X  escapes)  is
+       slow,  because  PCRE2 has to use a multi-stage table lookup whenever it
+       needs a character's property. If you can find  an  alternative  pattern
+       that does not use character properties, it will probably be faster.
+
+       By  default,  the  escape  sequences  \b, \d, \s, and \w, and the POSIX
+       character classes such as [:alpha:]  do  not  use  Unicode  properties,
+       partly for backwards compatibility, and partly for performance reasons.
+       However,  you  can  set  the PCRE2_UCP option or start the pattern with
+       (*UCP) if you want Unicode character properties to be  used.  This  can
+       double  the  matching  time  for  items  such  as \d, when matched with
+       pcre2_match(); the performance loss is less with a DFA  matching  func-
+       tion, and in both cases there is not much difference for \b.
+
+       When  a pattern begins with .* not in atomic parentheses, nor in paren-
+       theses that are the subject of a backreference,  and  the  PCRE2_DOTALL
+       option  is  set,  the pattern is implicitly anchored by PCRE2, since it
+       can match only at the start of a subject string.  If  the  pattern  has
+       multiple top-level branches, they must all be anchorable. The optimiza-
+       tion  can be disabled by the PCRE2_NO_DOTSTAR_ANCHOR option, and is au-
+       tomatically disabled if the pattern contains (*PRUNE) or (*SKIP).
+
+       If PCRE2_DOTALL is not set, PCRE2 cannot make  this  optimization,  be-
+       cause  the  dot metacharacter does not then match a newline, and if the
+       subject string contains newlines, the pattern may match from the  char-
+       acter immediately following one of them instead of from the very start.
+       For example, the pattern
+
+         .*second
+
+       matches  the subject "first\nand second" (where \n stands for a newline
+       character), with the match starting at the seventh character. In  order
+       to  do  this, PCRE2 has to retry the match starting after every newline
+       in the subject.
+
+       If you are using such a pattern with subject strings that do  not  con-
+       tain   newlines,   the   best   performance   is  obtained  by  setting
+       PCRE2_DOTALL, or starting the pattern with ^.* or ^.*? to indicate  ex-
+       plicit  anchoring.  That saves PCRE2 from having to scan along the sub-
+       ject looking for a newline to restart at.
+
+       Beware of patterns that contain nested indefinite  repeats.  These  can
+       take  a  long time to run when applied to a string that does not match.
+       Consider the pattern fragment
+
+         ^(a+)*
+
+       This can match "aaaa" in 16 different ways, and this  number  increases
+       very  rapidly  as the string gets longer. (The * repeat can match 0, 1,
+       2, 3, or 4 times, and for each of those cases other than 0 or 4, the  +
+       repeats  can  match  different numbers of times.) When the remainder of
+       the pattern is such that the entire match is going to fail,  PCRE2  has
+       in  principle to try every possible variation, and this can take an ex-
+       tremely long time, even for relatively short strings.
+
+       An optimization catches some of the more simple cases such as
+
+         (a+)*b
+
+       where a literal character follows. Before  embarking  on  the  standard
+       matching  procedure, PCRE2 checks that there is a "b" later in the sub-
+       ject string, and if there is not, it fails the match immediately.  How-
+       ever,  when  there  is no following literal this optimization cannot be
+       used. You can see the difference by comparing the behaviour of
+
+         (a+)*\d
+
+       with the pattern above. The former gives  a  failure  almost  instantly
+       when  applied  to  a  whole  line of "a" characters, whereas the latter
+       takes an appreciable time with strings longer than about 20 characters.
+
+       In many cases, the solution to this kind of performance issue is to use
+       an atomic group or a possessive quantifier. This can often reduce  mem-
+       ory requirements as well. As another example, consider this pattern:
+
+         ([^<]|<(?!inet))+
+
+       It  matches  from wherever it starts until it encounters "
+
+       int pcre2_regcomp(regex_t *preg, const char *pattern,
+            int cflags);
+
+       int pcre2_regexec(const regex_t *preg, const char *string,
+            size_t nmatch, regmatch_t pmatch[], int eflags);
+
+       size_t pcre2_regerror(int errcode, const regex_t *preg,
+            char *errbuf, size_t errbuf_size);
+
+       void pcre2_regfree(regex_t *preg);

+
+DESCRIPTION
+
+       This  set of functions provides a POSIX-style API for the PCRE2 regular
+       expression 8-bit library. There are no POSIX-style wrappers for PCRE2's
+       16-bit and 32-bit libraries. See the pcre2api documentation for  a  de-
+       scription  of  PCRE2's native API, which contains much additional func-
+       tionality.
+
+       IMPORTANT NOTE: The functions described here are NOT  thread-safe,  and
+       should  not  be used in multi-threaded applications. They are also lim-
+       ited to processing subjects that are not bigger than 2GB. Use  the  na-
+       tive API instead.
+
+       These  functions  are  wrapper functions that ultimately call the PCRE2
+       native API. Their prototypes are defined  in  the  pcre2posix.h  header
+       file, and they all have unique names starting with pcre2_. However, the
+       pcre2posix.h  header  also  contains macro definitions that convert the
+       standard POSIX names such  regcomp()  into  pcre2_regcomp()  etc.  This
+       means  that a program can use the usual POSIX names without running the
+       risk of accidentally linking with POSIX functions from a different  li-
+       brary.
+
+       On  Unix-like systems the PCRE2 POSIX library is called libpcre2-posix,
+       so can be accessed by adding -lpcre2-posix to the command  for  linking
+       an application. Because the POSIX functions call the native ones, it is
+       also necessary to add -lpcre2-8.
+
+       On Windows systems, if you are linking to a DLL version of the library,
+       it  is  recommended  that PCRE2POSIX_SHARED is defined before including
+       the pcre2posix.h header, as it will allow for a more efficient  way  to
+       invoke the functions by adding the __declspec(dllimport) decorator.
+
+       Although  they were not defined as prototypes in pcre2posix.h, releases
+       10.33 to 10.36 of the library contained functions with the POSIX  names
+       regcomp()  etc.  These simply passed their arguments to the PCRE2 func-
+       tions. These functions were provided for backwards  compatibility  with
+       earlier  versions  of  PCRE2, which had only POSIX names. However, this
+       has proved troublesome in situations where a program links with several
+       libraries, some of which use PCRE2's POSIX interface while  others  use
+       the  real  POSIX functions.  For this reason, the POSIX names have been
+       removed since release 10.37.
+
+       Calling the header file pcre2posix.h avoids  any  conflict  with  other
+       POSIX  libraries.  It can, of course, be renamed or aliased as regex.h,
+       which is the "correct" name, if there is  no  clash.  It  provides  two
+       structure  types,  regex_t  for compiled internal forms, and regmatch_t
+       for returning captured substrings. It also defines some constants whose
+       names start with "REG_"; these are used for setting options and identi-
+       fying error codes.
+
+
+USING THE POSIX FUNCTIONS
+
+       Note that these functions are just POSIX-style wrappers for PCRE2's na-
+       tive API.  They do not give POSIX  regular  expression  behaviour,  and
+       they are not thread-safe or even POSIX compatible.
+
+       Those  POSIX  option bits that can reasonably be mapped to PCRE2 native
+       options have been implemented. In addition, the option REG_EXTENDED  is
+       defined  with  the  value  zero. This has no effect, but since programs
+       that are written to the POSIX interface often use  it,  this  makes  it
+       easier  to  slot in PCRE2 as a replacement library. Other POSIX options
+       are not even defined.
+
+       There are also some options that are not defined by POSIX.  These  have
+       been  added  at  the  request  of users who want to make use of certain
+       PCRE2-specific features via the POSIX calling interface or to  add  BSD
+       or GNU functionality.
+
+       When  PCRE2  is  called via these functions, it is only the API that is
+       POSIX-like in style. The syntax and semantics of  the  regular  expres-
+       sions  themselves  are  still  those of Perl, subject to the setting of
+       various PCRE2 options, as described below. "POSIX-like in style"  means
+       that  the  API  approximates  to  the POSIX definition; it is not fully
+       POSIX-compatible, and in multi-unit encoding  domains  it  is  probably
+       even less compatible.
+
+       The  descriptions  below use the actual names of the functions, but, as
+       described above, the standard POSIX names (without the  pcre2_  prefix)
+       may also be used.
+
+
+COMPILING A PATTERN
+
+       The function pcre2_regcomp() is called to compile a pattern into an in-
+       ternal  form. By default, the pattern is a C string terminated by a bi-
+       nary zero (but see REG_PEND below). The preg argument is a pointer to a
+       regex_t structure that is used as a base for storing information  about
+       the  compiled  regular  expression.  It  is  also  used  for input when
+       REG_PEND is set. The regex_t structure used by pcre2_regcomp()  is  de-
+       fined  in  pcre2posix.h  and  is  not the same as the structure used by
+       other libraries that provide POSIX-style matching.
+
+       The argument cflags is either zero, or contains one or more of the bits
+       defined by the following macros:
+
+         REG_DOTALL
+
+       The PCRE2_DOTALL option is set when the regular  expression  is  passed
+       for  compilation  to  the  native function. Note that REG_DOTALL is not
+       part of the POSIX standard.
+
+         REG_ICASE
+
+       The PCRE2_CASELESS option is set when the regular expression is  passed
+       for compilation to the native function.
+
+         REG_NEWLINE
+
+       The PCRE2_MULTILINE option is set when the regular expression is passed
+       for  compilation  to the native function. Note that this does not mimic
+       the defined POSIX behaviour for REG_NEWLINE  (see  the  following  sec-
+       tion).
+
+         REG_NOSPEC
+
+       The  PCRE2_LITERAL  option is set when the regular expression is passed
+       for compilation to the native function. This disables all meta  charac-
+       ters  in the pattern, causing it to be treated as a literal string. The
+       only other options that are  allowed  with  REG_NOSPEC  are  REG_ICASE,
+       REG_NOSUB,  REG_PEND,  and REG_UTF. Note that REG_NOSPEC is not part of
+       the POSIX standard.
+
+         REG_NOSUB
+
+       When  a  pattern  that  is  compiled  with  this  flag  is  passed   to
+       pcre2_regexec()  for  matching, the nmatch and pmatch arguments are ig-
+       nored, and no captured strings are returned. Versions of the  PCRE  li-
+       brary  prior to 10.22 used to set the PCRE2_NO_AUTO_CAPTURE compile op-
+       tion, but this no longer happens because it disables the use  of  back-
+       references.
+
+         REG_PEND
+
+       If  this option is set, the reg_endp field in the preg structure (which
+       has the type const char *) must be set to point to the character beyond
+       the end of the pattern before calling pcre2_regcomp(). The pattern  it-
+       self  may  now  contain binary zeros, which are treated as data charac-
+       ters. Without REG_PEND, a binary zero terminates the  pattern  and  the
+       re_endp field is ignored. This is a GNU extension to the POSIX standard
+       and  should be used with caution in software intended to be portable to
+       other systems.
+
+         REG_UCP
+
+       The PCRE2_UCP option is set when the regular expression is  passed  for
+       compilation  to  the  native function. This causes PCRE2 to use Unicode
+       properties when matching \d, \w,  etc.,  instead  of  just  recognizing
+       ASCII values. Note that REG_UCP is not part of the POSIX standard.
+
+         REG_UNGREEDY
+
+       The  PCRE2_UNGREEDY option is set when the regular expression is passed
+       for compilation to the native function. Note that REG_UNGREEDY  is  not
+       part of the POSIX standard.
+
+         REG_UTF
+
+       The  PCRE2_UTF  option is set when the regular expression is passed for
+       compilation to the native function. This causes the pattern itself  and
+       all  data  strings used for matching it to be treated as UTF-8 strings.
+       Note that REG_UTF is not part of the POSIX standard.
+
+       In the absence of these flags, no options  are  passed  to  the  native
+       function.  This means that the regex is compiled with PCRE2 default se-
+       mantics.  In  particular,  the way it handles newline characters in the
+       subject string is the Perl way, not the POSIX way.  Note  that  setting
+       PCRE2_MULTILINE has only some of the effects specified for REG_NEWLINE.
+       It  does not affect the way newlines are matched by the dot metacharac-
+       ter (they are not) or by a negative class such as [^a] (they are).
+
+       The yield of pcre2_regcomp() is zero on success,  and  non-zero  other-
+       wise.  The preg structure is filled in on success, and one other member
+       of  the  structure (as well as re_endp) is public: re_nsub contains the
+       number of capturing subpatterns in the regular expression. Various  er-
+       ror codes are defined in the header file.
+
+       NOTE: If the yield of pcre2_regcomp() is non-zero, you must not attempt
+       to use the contents of the preg structure. If, for example, you pass it
+       to  pcre2_regexec(), the result is undefined and your program is likely
+       to crash.
+
+
+MATCHING NEWLINE CHARACTERS
+
+       This area is not simple, because POSIX and Perl take different views of
+       things.  It is not possible to get PCRE2 to obey POSIX  semantics,  but
+       then PCRE2 was never intended to be a POSIX engine. The following table
+       lists  the  different  possibilities for matching newline characters in
+       Perl and PCRE2:
+
+                                 Default   Change with
+
+         . matches newline          no     PCRE2_DOTALL
+         newline matches [^a]       yes    not changeable
+         $ matches \n at end        yes    PCRE2_DOLLAR_ENDONLY
+         $ matches \n in middle     no     PCRE2_MULTILINE
+         ^ matches \n in middle     no     PCRE2_MULTILINE
+
+       This is the equivalent table for a POSIX-compatible pattern matcher:
+
+                                 Default   Change with
+
+         . matches newline          yes    REG_NEWLINE
+         newline matches [^a]       yes    REG_NEWLINE
+         $ matches \n at end        no     REG_NEWLINE
+         $ matches \n in middle     no     REG_NEWLINE
+         ^ matches \n in middle     no     REG_NEWLINE
+
+       This behaviour is not what happens when PCRE2 is called via  its  POSIX
+       API.  By  default, PCRE2's behaviour is the same as Perl's, except that
+       there is no equivalent for PCRE2_DOLLAR_ENDONLY in Perl. In both  PCRE2
+       and Perl, there is no way to stop newline from matching [^a].
+
+       Default  POSIX newline handling can be obtained by setting PCRE2_DOTALL
+       and PCRE2_DOLLAR_ENDONLY when  calling  pcre2_compile()  directly,  but
+       there is no way to make PCRE2 behave exactly as for the REG_NEWLINE ac-
+       tion.  When  using  the  POSIX  API,  passing  REG_NEWLINE  to  PCRE2's
+       pcre2_regcomp()  function  causes  PCRE2_MULTILINE  to  be  passed   to
+       pcre2_compile(), and REG_DOTALL passes PCRE2_DOTALL. There is no way to
+       pass PCRE2_DOLLAR_ENDONLY.
+

+       The function pcre2_regexec() is called to match a compiled pattern preg
+       against  a  given string, which is by default terminated by a zero byte
+       (but see REG_STARTEND below), subject to the options in eflags.   These
+       can be:
+
+         REG_NOTBOL
+
+       The PCRE2_NOTBOL option is set when calling the underlying PCRE2 match-
+       ing function.
+
+         REG_NOTEMPTY
+
+       The  PCRE2_NOTEMPTY  option  is  set  when calling the underlying PCRE2
+       matching function. Note that REG_NOTEMPTY is  not  part  of  the  POSIX
+       standard.  However, setting this option can give more POSIX-like behav-
+       iour in some situations.
+
+         REG_NOTEOL
+
+       The PCRE2_NOTEOL option is set when calling the underlying PCRE2 match-
+       ing function.
+
+         REG_STARTEND
+
+       When this option  is  set,  the  subject  string  starts  at  string  +
+       pmatch[0].rm_so  and  ends  at  string  + pmatch[0].rm_eo, which should
+       point to the first character beyond the string. There may be binary ze-
+       ros within the subject string, and indeed, using  REG_STARTEND  is  the
+       only way to pass a subject string that contains a binary zero.
+
+       Whatever  the  value  of  pmatch[0].rm_so,  the  offsets of the matched
+       string and any captured substrings are  still  given  relative  to  the
+       start  of  string  itself. (Before PCRE2 release 10.30 these were given
+       relative to string + pmatch[0].rm_so, but this differs from  other  im-
+       plementations.)
+
+       This  is  a  BSD  extension,  compatible with but not specified by IEEE
+       Standard 1003.2 (POSIX.2), and should be used with caution in  software
+       intended  to  be  portable to other systems. Note that a non-zero rm_so
+       does not imply REG_NOTBOL; REG_STARTEND affects only the  location  and
+       length  of  the string, not how it is matched. Setting REG_STARTEND and
+       passing pmatch as NULL are mutually exclusive; the error REG_INVARG  is
+       returned.
+
+       If  the pattern was compiled with the REG_NOSUB flag, no data about any
+       matched strings  is  returned.  The  nmatch  and  pmatch  arguments  of
+       pcre2_regexec()  are  ignored  (except  possibly as input for REG_STAR-
+       TEND).
+
+       The value of nmatch may be zero, and the value pmatch may be NULL  (un-
+       less  REG_STARTEND  is  set);  in  both  these  cases no data about any
+       matched strings is returned.
+
+       Otherwise, the portion of the string that was  matched,  and  also  any
+       captured substrings, are returned via the pmatch argument, which points
+       to  an  array  of  nmatch structures of type regmatch_t, containing the
+       members rm_so and rm_eo. These contain the byte  offset  to  the  first
+       character of each substring and the offset to the first character after
+       the  end of each substring, respectively. The 0th element of the vector
+       relates to the entire portion of string that  was  matched;  subsequent
+       elements relate to the capturing subpatterns of the regular expression.
+       Unused entries in the array have both structure members set to -1.
+
+       regmatch_t  as  well  as  the  regoff_t  typedef it uses are defined in
+       pcre2posix.h and are not warranted to have the same size or  layout  as
+       other  similarly  named  types from other libraries that provide POSIX-
+       style matching.
+
+       A successful match yields a zero return; various error  codes  are  de-
+       fined  in the header file, of which REG_NOMATCH is the "expected" fail-
+       ure code.
+
+
+ERROR MESSAGES
+
+       The pcre2_regerror() function maps a  non-zero  errorcode  from  either
+       pcre2_regcomp()  or  pcre2_regexec() to a printable message. If preg is
+       not NULL, the error should have arisen from the use of that  structure.
+       A  message  terminated  by  a  binary  zero is placed in errbuf. If the
+       buffer is too short, only the first errbuf_size - 1 characters  of  the
+       error message are used. The yield of the function is the size of buffer
+       needed  to hold the whole message, including the terminating zero. This
+       value is greater than errbuf_size if the message was truncated.
+
+
+MEMORY USAGE
+
+       Compiling a regular expression causes memory to be allocated and  asso-
+       ciated  with the preg structure. The function pcre2_regfree() frees all
+       such memory, after which preg may no longer be used as a  compiled  ex-
+       pression.

+
+PCRE2 SAMPLE PROGRAM
+
+       A  simple, complete demonstration program to get you started with using
+       PCRE2 is supplied in the file pcre2demo.c in the src directory  in  the
+       PCRE2 distribution. A listing of this program is given in the pcre2demo
+       documentation. If you do not have a copy of the PCRE2 distribution, you
+       can save this listing to re-create the contents of pcre2demo.c.
+
+       The  demonstration  program compiles the regular expression that is its
+       first argument, and matches it against the subject string in its second
+       argument. No PCRE2 options are set, and default  character  tables  are
+       used. If matching succeeds, the program outputs the portion of the sub-
+       ject  that  matched,  together  with  the contents of any captured sub-
+       strings.
+
+       If the -g option is given on the command line, the program then goes on
+       to check for further matches of the same regular expression in the same
+       subject string. The logic is a little bit tricky because of the  possi-
+       bility  of  matching an empty string. Comments in the code explain what
+       is going on.
+
+       The code in pcre2demo.c is an 8-bit program that uses the  PCRE2  8-bit
+       library.  It  handles  strings  and characters that are stored in 8-bit
+       code units.  By default, one character corresponds to  one  code  unit,
+       but  if  the  pattern starts with "(*UTF)", both it and the subject are
+       treated as UTF-8 strings, where characters  may  occupy  multiple  code
+       units.
+
+       If  PCRE2  is installed in the standard include and library directories
+       for your operating system, you should be able to compile the demonstra-
+       tion program using a command like this:
+
+         cc -o pcre2demo pcre2demo.c -lpcre2-8
+
+       If PCRE2 is installed elsewhere, you may need to add additional options
+       to the command line. For example, on a Unix-like system that has  PCRE2
+       installed  in /usr/local, you can compile the demonstration program us-
+       ing a command like this:
+
+         cc -o pcre2demo -I/usr/local/include pcre2demo.c \
+            -L/usr/local/lib -lpcre2-8
+
+       Once you have built the demonstration program, you can run simple tests
+       like this:
+
+         ./pcre2demo 'cat|dog' 'the cat sat on the mat'
+         ./pcre2demo -g 'cat|dog' 'the dog sat on the cat'
+
+       Note that there is a  much  more  comprehensive  test  program,  called
+       pcre2test,  which supports many more facilities for testing regular ex-
+       pressions using all three PCRE2 libraries (8-bit, 16-bit,  and  32-bit,
+       though  not all three need be installed). The pcre2demo program is pro-
+       vided as a relatively simple coding example.
+
+       If you try to run pcre2demo when PCRE2 is not installed in the standard
+       library directory, you may get an error like  this  on  some  operating
+       systems (e.g. Solaris):
+
+         ld.so.1: pcre2demo: fatal: libpcre2-8.so.0: open failed: No such file
+       or directory
+
+       This  is  caused  by the way shared library support works on those sys-
+       tems. You need to add
+
+         -R/usr/local/lib
+
+       (for example) to the compile command to get round this problem.

+
+       If  you  are running an application that uses a large number of regular
+       expression patterns, it may be useful to store them  in  a  precompiled
+       form  instead  of  having to compile them every time the application is
+       run. However, if you are using the just-in-time  optimization  feature,
+       it is not possible to save and reload the JIT data, because it is posi-
+       tion-dependent.  The  host  on  which the patterns are reloaded must be
+       running the same version of PCRE2, with the same code unit  width,  and
+       must  also have the same endianness, pointer width and PCRE2_SIZE type.
+       For example, patterns compiled on a 32-bit system using PCRE2's  16-bit
+       library cannot be reloaded on a 64-bit system, nor can they be reloaded
+       using the 8-bit library.
+
+       Note  that  "serialization" in PCRE2 does not convert compiled patterns
+       to an abstract format like Java or .NET serialization.  The  serialized
+       output  is really just a bytecode dump, which is why it can only be re-
+       loaded in the same environment as the one that created  it.  Hence  the
+       restrictions  mentioned  above.   Applications  that are not statically
+       linked with a fixed version of PCRE2 must be prepared to recompile pat-
+       terns from their sources, in order to be immune to PCRE2 upgrades.
+
+
+SECURITY CONCERNS
+
+       The facility for saving and restoring compiled patterns is intended for
+       use within individual applications.  As  such,  the  data  supplied  to
+       pcre2_serialize_decode()  is expected to be trusted data, not data from
+       arbitrary external sources.  There  is  only  some  simple  consistency
+       checking, not complete validation of what is being re-loaded. Corrupted
+       data may cause undefined results. For example, if the length field of a
+       pattern in the serialized data is corrupted, the deserializing code may
+       read beyond the end of the byte stream that is passed to it.
+
+
+SAVING COMPILED PATTERNS
+
+       Before compiled patterns can be saved they must be serialized, which in
+       PCRE2  means converting the pattern to a stream of bytes. A single byte
+       stream may contain any number of compiled patterns, but they  must  all
+       use  the same character tables. A single copy of the tables is included
+       in the byte stream (its size is 1088 bytes). For more details of  char-
+       acter  tables,  see the section on locale support in the pcre2api docu-
+       mentation.
+
+       The function pcre2_serialize_encode() creates a serialized byte  stream
+       from  a  list of compiled patterns. Its first two arguments specify the
+       list, being a pointer to a vector of pointers to compiled patterns, and
+       the length of the vector. The third and fourth arguments point to vari-
+       ables which are set to point to the created byte stream and its length,
+       respectively. The final argument is a pointer  to  a  general  context,
+       which  can  be  used  to specify custom memory management functions. If
+       this argument is NULL, malloc() is used to obtain memory for  the  byte
+       stream. The yield of the function is the number of serialized patterns,
+       or one of the following negative error codes:
+
+         PCRE2_ERROR_BADDATA      the number of patterns is zero or less
+         PCRE2_ERROR_BADMAGIC     mismatch of id bytes in one of the patterns
+         PCRE2_ERROR_NOMEMORY     memory allocation failed
+         PCRE2_ERROR_MIXEDTABLES  the patterns do not all use the same tables
+         PCRE2_ERROR_NULL         the 1st, 3rd, or 4th argument is NULL
+
+       PCRE2_ERROR_BADMAGIC  means  either that a pattern's code has been cor-
+       rupted, or that a slot in the vector does not point to a compiled  pat-
+       tern.
+
+       Once a set of patterns has been serialized you can save the data in any
+       appropriate  manner. Here is sample code that compiles two patterns and
+       writes them to a file. It assumes that the variable fd refers to a file
+       that is open for output. The error checking that should be present in a
+       real application has been omitted for simplicity.
+
+         int errorcode;
+         uint8_t *bytes;
+         PCRE2_SIZE erroroffset;
+         PCRE2_SIZE bytescount;
+         pcre2_code *list_of_codes[2];
+         list_of_codes[0] = pcre2_compile("first pattern",
+           PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+         list_of_codes[1] = pcre2_compile("second pattern",
+           PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+         errorcode = pcre2_serialize_encode(list_of_codes, 2, &bytes,
+           &bytescount, NULL);
+         errorcode = fwrite(bytes, 1, bytescount, fd);
+
+       Note that the serialized data is binary data that may  contain  any  of
+       the  256  possible  byte values. On systems that make a distinction be-
+       tween binary and non-binary data, be sure that the file is  opened  for
+       binary output.
+
+       Serializing  a  set  of patterns leaves the original data untouched, so
+       they can still be used for matching. Their memory  must  eventually  be
+       freed in the usual way by calling pcre2_code_free(). When you have fin-
+       ished with the byte stream, it too must be freed by calling pcre2_seri-
+       alize_free().  If  this function is called with a NULL argument, it re-
+       turns immediately without doing anything.
+
+
+RE-USING PRECOMPILED PATTERNS
+
+       In order to re-use a set of saved patterns you must first make the  se-
+       rialized  byte stream available in main memory (for example, by reading
+       from a file). The management of this memory block is up to the applica-
+       tion. You can use the pcre2_serialize_get_number_of_codes() function to
+       find out how many compiled patterns are in the serialized data  without
+       actually decoding the patterns:
+
+         uint8_t *bytes = ;
+         int32_t number_of_codes = pcre2_serialize_get_number_of_codes(bytes);
+
+       The pcre2_serialize_decode() function reads a byte stream and recreates
+       the compiled patterns in new memory blocks, setting pointers to them in
+       a  vector.  The  first two arguments are a pointer to a suitable vector
+       and its length, and the third argument points to a byte stream. The fi-
+       nal argument is a pointer to a general context, which can  be  used  to
+       specify custom memory management functions for the decoded patterns. If
+       this argument is NULL, malloc() and free() are used. After deserializa-
+       tion, the byte stream is no longer needed and can be discarded.
+
+         pcre2_code *list_of_codes[2];
+         uint8_t *bytes = ;
+         int32_t number_of_codes =
+           pcre2_serialize_decode(list_of_codes, 2, bytes, NULL);
+
+       If  the  vector  is  not  large enough for all the patterns in the byte
+       stream, it is filled with those that fit, and  the  remainder  are  ig-
+       nored.  The yield of the function is the number of decoded patterns, or
+       one of the following negative error codes:
+
+         PCRE2_ERROR_BADDATA    second argument is zero or less
+         PCRE2_ERROR_BADMAGIC   mismatch of id bytes in the data
+         PCRE2_ERROR_BADMODE    mismatch of code unit size or PCRE2 version
+         PCRE2_ERROR_BADSERIALIZEDDATA  other sanity check failure
+         PCRE2_ERROR_MEMORY     memory allocation failed
+         PCRE2_ERROR_NULL       first or third argument is NULL
+
+       PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it  was
+       compiled on a system with different endianness.
+
+       Decoded patterns can be used for matching in the usual way, and must be
+       freed  by  calling pcre2_code_free(). However, be aware that there is a
+       potential race issue if you are using multiple patterns that  were  de-
+       coded  from a single byte stream in a multithreaded application. A sin-
+       gle copy of the character tables is used by all  the  decoded  patterns
+       and a reference count is used to arrange for its memory to be automati-
+       cally  freed when the last pattern is freed, but there is no locking on
+       this reference count. Therefore, if you want to call  pcre2_code_free()
+       for  these  patterns  in  different  threads, you must arrange your own
+       locking, and ensure that pcre2_code_free()  cannot  be  called  by  two
+       threads at the same time.
+
+       If  a pattern was processed by pcre2_jit_compile() before being serial-
+       ized, the JIT data is discarded and so is no longer available  after  a
+       save/restore  cycle.  You can, however, process a restored pattern with
+       pcre2_jit_compile() if you wish.

+       PCRE2 - Perl-compatible regular expressions (revised API)
+
+
+PCRE2 REGULAR EXPRESSION SYNTAX SUMMARY
+
+       The  full syntax and semantics of the regular expressions that are sup-
+       ported by PCRE2 are described in the pcre2pattern  documentation.  This
+       document contains a quick-reference summary of the syntax.
+
+
+QUOTING
+
+         \x         where x is non-alphanumeric is a literal x
+         \Q...\E    treat enclosed characters as literal
+
+       Note that white space inside \Q...\E is always treated as literal, even
+       if PCRE2_EXTENDED is set, causing most other white space to be ignored.
+
+
+BRACED ITEMS
+
+       With  one  exception, wherever brace characters { and } are required to
+       enclose data for constructions such as \g{2} or \k{name}, space  and/or
+       horizontal  tab  characters  that follow { or precede } are allowed and
+       are ignored. In the case of quantifiers, they may also appear before or
+       after the comma. The exception is \u{...} which is not  Perl-compatible
+       and is recognized only when PCRE2_EXTRA_ALT_BSUX is set. This is an EC-
+       MAScript compatibility feature, and follows ECMAScript's behaviour.
+
+
+ESCAPED CHARACTERS
+
+       This  table  applies to ASCII and Unicode environments. An unrecognized
+       escape sequence causes an error.
+
+         \a         alarm, that is, the BEL character (hex 07)
+         \cx        "control-x", where x is a non-control ASCII character
+         \e         escape (hex 1B)
+         \f         form feed (hex 0C)
+         \n         newline (hex 0A)
+         \r         carriage return (hex 0D)
+         \t         tab (hex 09)
+         \0dd       character with octal code 0dd
+         \ddd       character with octal code ddd, or backreference
+         \o{ddd..}  character with octal code ddd..
+         \N{U+hh..} character with Unicode code point hh.. (Unicode mode only)
+         \xhh       character with hex code hh
+         \x{hh..}   character with hex code hh..
+
+       If PCRE2_ALT_BSUX or PCRE2_EXTRA_ALT_BSUX is set ("ALT_BSUX mode"), the
+       following are also recognized:
+
+         \U         the character "U"
+         \uhhhh     character with hex code hhhh
+         \u{hh..}   character with hex code hh.. but only for EXTRA_ALT_BSUX
+
+       When \x is not followed by {, from zero to two hexadecimal  digits  are
+       read,  but in ALT_BSUX mode \x must be followed by two hexadecimal dig-
+       its to be recognized as a hexadecimal escape; otherwise  it  matches  a
+       literal  "x".   Likewise,  if  \u (in ALT_BSUX mode) is not followed by
+       four hexadecimal digits or (in EXTRA_ALT_BSUX mode) a sequence  of  hex
+       digits in curly brackets, it matches a literal "u".
+
+       Note that \0dd is always an octal code. The treatment of backslash fol-
+       lowed  by  a non-zero digit is complicated; for details see the section
+       "Non-printing characters" in the pcre2pattern documentation, where  de-
+       tails  of  escape  processing  in  EBCDIC  environments are also given.
+       \N{U+hh..} is synonymous with \x{hh..} in PCRE2 but is not supported in
+       EBCDIC environments. Note that \N not  followed  by  an  opening  curly
+       bracket has a different meaning (see below).

+
+CHARACTER TYPES
+
+         .          any character except newline;
+                      in dotall mode, any character whatsoever
+         \C         one code unit, even in UTF mode (best avoided)
+         \d         a decimal digit
+         \D         a character that is not a decimal digit
+         \h         a horizontal white space character
+         \H         a character that is not a horizontal white space character
+         \N         a character that is not a newline
+         \p{xx}     a character with the xx property
+         \P{xx}     a character without the xx property
+         \R         a newline sequence
+         \s         a white space character
+         \S         a character that is not a white space character
+         \v         a vertical white space character
+         \V         a character that is not a vertical white space character
+         \w         a "word" character
+         \W         a "non-word" character
+         \X         a Unicode extended grapheme cluster
+
+       \C  is dangerous because it may leave the current matching point in the
+       middle of a UTF-8 or UTF-16 character. The application can lock out the
+       use of \C by setting the PCRE2_NEVER_BACKSLASH_C  option.  It  is  also
+       possible to build PCRE2 with the use of \C permanently disabled.
+
+       By  default,  \d, \s, and \w match only ASCII characters, even in UTF-8
+       mode or in the 16-bit and 32-bit libraries. However, if locale-specific
+       matching is happening, \s and \w may also match  characters  with  code
+       points in the range 128-255. If the PCRE2_UCP option is set, the behav-
+       iour of these escape sequences is changed to use Unicode properties and
+       they  match  many  more  characters, but there are some option settings
+       that can restrict individual sequences to matching only  ASCII  charac-
+       ters.
+
+       Property descriptions in \p and \P are matched caselessly; hyphens, un-
+       derscores,  and  white  space are ignored, in accordance with Unicode's
+       "loose matching" rules.

+
+
+BINARY PROPERTIES FOR \p AND \P
+
+       Unicode defines a number of  binary  properties,  that  is,  properties
+       whose  only  values  are  true or false. You can obtain a list of those
+       that are recognized by \p and \P, along with  their  abbreviations,  by
+       running this command:
+
+         pcre2test -LP
+
+
+SCRIPT MATCHING WITH \p AND \P
+
+       Many  script  names  and their 4-letter abbreviations are recognized in
+       \p{sc:...} or \p{scx:...} items, or on their own with \p (and  also  \P
+       of course). You can obtain a list of these scripts by running this com-
+       mand:

+OPTION SETTING
+       Changes  of these options within a group are automatically cancelled at
+       the end of the group.
+
+         (?a)            all ASCII options
+         (?aD)           restrict \d to ASCII in UCP mode
+         (?aS)           restrict \s to ASCII in UCP mode
+         (?aW)           restrict \w to ASCII in UCP mode

+         (?J)            allow duplicate named groups
+         (?m)            multiline
+         (?n)            no auto capture
+         (?r)            restrict caseless to either ASCII or non-ASCII
+         (?s)            single line (dotall)
+         (?U)            default ungreedy (lazy)
+         (?x)            ignore white space except in classes or \Q...\E
+         (?xx)           as (?x) but also ignore space and tab in classes
+         (?-...)         unset the given option(s)
+         (?^)            unset imnrsx options
+
+       (?aP) implies (?aT) as well, though this has no additional effect. How-
+       ever, it means that (?-aP) is really (?-PT) which  disables  all  ASCII
+       restrictions for POSIX classes.
+
+       Unsetting  x or xx unsets both. Several options may be set at once, and
+       a mixture of setting and unsetting such as (?i-x) is allowed, but there
+       may be only one hyphen. Setting (but no unsetting) is allowed after (?^
+       for example (?^in). An option setting may appear at the start of a non-
+       capture group, for example (?i:...).
+
+       The following are recognized only at the very start of a pattern or af-
+       ter one of the newline or \R options with similar syntax. More than one
+       of them may appear. For the first three, d is a decimal number.
+
+         (*LIMIT_DEPTH=d) set the backtracking limit to d
+         (*LIMIT_HEAP=d)  set the heap size limit to d * 1024 bytes
+         (*LIMIT_MATCH=d) set the match limit to d
+         (*NOTEMPTY)      set PCRE2_NOTEMPTY when matching
+         (*NOTEMPTY_ATSTART) set PCRE2_NOTEMPTY_ATSTART when matching
+         (*NO_AUTO_POSSESS) no auto-possessification (PCRE2_NO_AUTO_POSSESS)
+         (*NO_DOTSTAR_ANCHOR) no .* anchoring (PCRE2_NO_DOTSTAR_ANCHOR)
+         (*NO_JIT)       disable JIT optimization
+         (*NO_START_OPT) no start-match optimization (PCRE2_NO_START_OPTIMIZE)
+         (*UTF)          set appropriate UTF mode for the library in use
+         (*UCP)          set PCRE2_UCP (use Unicode properties for \d etc)
+
+       Note that LIMIT_DEPTH, LIMIT_HEAP, and LIMIT_MATCH can only reduce  the
+       value   of   the   limits   set  by  the  caller  of  pcre2_match()  or
+       pcre2_dfa_match(), not increase them. LIMIT_RECURSION  is  an  obsolete
+       synonym for LIMIT_DEPTH. The application can lock out the use of (*UTF)
+       and  (*UCP)  by setting the PCRE2_NEVER_UTF or PCRE2_NEVER_UCP options,
+       respectively, at compile time.

+
+
+BACKTRACKING CONTROL
+
+       All  backtracking  control  verbs  may be in the form (*VERB:NAME). For
+       (*MARK) the name is mandatory, for the others it is  optional.  (*SKIP)
+       changes  its  behaviour if :NAME is present. The others just set a name
+       for passing back to the caller, but this is not a name that (*SKIP) can
+       see. The following act immediately they are reached:
+
+         (*ACCEPT)       force successful match
+         (*FAIL)         force backtrack; synonym (*F)
+         (*MARK:NAME)    set name to be passed back; synonym (*:NAME)
+
+       The following act only when a subsequent match failure causes  a  back-
+       track to reach them. They all force a match failure, but they differ in
+       what happens afterwards. Those that advance the start-of-match point do
+       so only if the pattern is not anchored.
+
+         (*COMMIT)       overall failure, no advance of starting point
+         (*PRUNE)        advance to next starting character
+         (*SKIP)         advance to current matching position
+         (*SKIP:NAME)    advance to position corresponding to an earlier
+                         (*MARK:NAME); if not found, the (*SKIP) is ignored
+         (*THEN)         local failure, backtrack to next alternation
+
+       The  effect  of one of these verbs in a group called as a subroutine is
+       confined to the subroutine call.
+

+CALLOUTS

+
+
+UNICODE AND UTF SUPPORT
+
+       PCRE2 is normally built with Unicode support, though if you do not need
+       it,  you  can  build  it  without,  in  which  case the library will be
+       smaller. With Unicode support, PCRE2 has knowledge of Unicode character
+       properties and can process strings of text in UTF-8, UTF-16, and UTF-32
+       format (depending on the code unit width), but this is not the default.
+       Unless specifically requested, PCRE2 treats each code unit in a  string
+       as one character.
+
+       There  are two ways of telling PCRE2 to switch to UTF mode, where char-
+       acters may consist of more than one code unit and the range  of  values
+       is constrained. The program can call pcre2_compile() with the PCRE2_UTF
+       option,  or  the  pattern may start with the sequence (*UTF).  However,
+       the latter facility can be locked out by  the  PCRE2_NEVER_UTF  option.
+       That  is,  the  programmer can prevent the supplier of the pattern from
+       switching to UTF mode.
+
+       Note  that  the  PCRE2_MATCH_INVALID_UTF  option  (see  below)   forces
+       PCRE2_UTF to be set.
+
+       In  UTF mode, both the pattern and any subject strings that are matched
+       against it are treated as UTF strings instead of strings of  individual
+       one-code-unit  characters. There are also some other changes to the way
+       characters are handled, as documented below.
+
+
+UNICODE PROPERTY SUPPORT
+
+       When PCRE2 is built with Unicode support, the escape sequences  \p{..},
+       \P{..}, and \X can be used. This is not dependent on the PCRE2_UTF set-
+       ting.   The Unicode properties that can be tested are a subset of those
+       that Perl supports. Currently they are limited to the general  category
+       properties such as Lu for an upper case letter or Nd for a decimal num-
+       ber, the derived properties Any and LC (synonym L&), the Unicode script
+       names such as Arabic or Han, Bidi_Class, Bidi_Control, and a few binary
+       properties.
+
+       The full lists are given in the pcre2pattern and pcre2syntax documenta-
+       tion.  In  general,  only the short names for properties are supported.
+       For example, \p{L} matches a letter. Its longer synonym, \p{Letter}, is
+       not supported. Furthermore, in Perl, many properties may optionally  be
+       prefixed  by "Is", for compatibility with Perl 5.6. PCRE2 does not sup-
+       port this.
+
+
+WIDE CHARACTERS AND UTF MODES
+
+       Code points less than 256 can be specified in patterns by either braced
+       or unbraced hexadecimal escape sequences (for example, \x{b3} or \xb3).
+       Larger values have to use braced sequences. Unbraced octal code  points
+       up to \777 are also recognized; larger ones can be coded using \o{...}.
+
+       The  escape sequence \N{U+} is recognized as another way of
+       specifying a Unicode character by code point in a UTF mode. It  is  not
+       allowed in non-UTF mode.
+
+       In  UTF  mode, repeat quantifiers apply to complete UTF characters, not
+       to individual code units.
+
+       In UTF mode, the dot metacharacter matches one UTF character instead of
+       a single code unit.
+
+       In UTF mode, capture group names are not restricted to ASCII,  and  may
+       contain any Unicode letters and decimal digits, as well as underscore.
+
+       The  escape  sequence \C can be used to match a single code unit in UTF
+       mode, but its use can lead to some strange effects because it breaks up
+       multi-unit characters (see the description of \C  in  the  pcre2pattern
+       documentation). For this reason, there is a build-time option that dis-
+       ables  support  for  \C completely. There is also a less draconian com-
+       pile-time option for locking out the use of \C when a pattern  is  com-
+       piled.
+
+       The  use  of  \C  is not supported by the alternative matching function
+       pcre2_dfa_match() when in UTF-8 or UTF-16 mode, that is, when a charac-
+       ter may consist of more than one code unit. The  use  of  \C  in  these
+       modes  provokes a match-time error. Also, the JIT optimization does not
+       support \C in these modes. If JIT optimization is requested for a UTF-8
+       or UTF-16 pattern that contains \C, it will not succeed,  and  so  when
+       pcre2_match() is called, the matching will be carried out by the inter-
+       pretive function.
+
+       The character escapes \b, \B, \d, \D, \s, \S, \w, and \W correctly test
+       characters  of  any  code  value,  but, by default, the characters that
+       PCRE2 recognizes as digits, spaces, or word characters remain the  same
+       set  as  in  non-UTF mode, all with code points less than 256. This re-
+       mains true even when PCRE2 is built to include Unicode support, because
+       to do otherwise would slow down matching in  many  common  cases.  Note
+       that  this also applies to \b and \B, because they are defined in terms
+       of \w and \W. If you want to test for a wider sense of,  say,  "digit",
+       you  can  use  explicit Unicode property tests such as \p{Nd}. Alterna-
+       tively, if you set the PCRE2_UCP option, the way that the character es-
+       capes work is changed so that Unicode properties are used to  determine
+       which  characters  match,  though  there are some options that suppress
+       this for individual escapes. For details see  the  section  on  generic
+       character types in the pcre2pattern documentation.
+
+       Like  the  escapes,  characters  that  match  the POSIX named character
+       classes are all low-valued characters unless the  PCRE2_UCP  option  is
+       set, but there is an option to override this.
+
+       In contrast to the character escapes and character classes, the special
+       horizontal  and  vertical  white  space escapes (\h, \H, \v, and \V) do
+       match all the appropriate Unicode characters, whether or not  PCRE2_UCP
+       is set.
+
+
+UNICODE CASE-EQUIVALENCE
+
+       If  either  PCRE2_UTF  or PCRE2_UCP is set, upper/lower case processing
+       makes use of Unicode properties except for characters whose code points
+       are less than 128 and that have at most two case-equivalent values. For
+       these, a direct table lookup is used for speed. A few  Unicode  charac-
+       ters  such as Greek sigma have more than two code points that are case-
+       equivalent, and these are treated specially. Setting PCRE2_UCP  without
+       PCRE2_UTF  allows  Unicode-style  case processing for non-UTF character
+       encodings such as UCS-2.
+
+       There are two ASCII characters (S and K) that,  in  addition  to  their
+       ASCII  lower case equivalents, have a non-ASCII one as well (long S and
+       Kelvin sign).  Recognition of these non-ASCII characters as case-equiv-
+       alent to their ASCII  counterparts  can  be  disabled  by  setting  the
+       PCRE2_EXTRA_CASELESS_RESTRICT  option. When this is set, all characters
+       in a case equivalence must either be ASCII or non-ASCII; there  can  be
+       no mixing.
+
+
+SCRIPT RUNS
+
+       The  pattern constructs (*script_run:...) and (*atomic_script_run:...),
+       with synonyms (*sr:...) and (*asr:...), verify that the string  matched
+       within  the  parentheses is a script run. In concept, a script run is a
+       sequence of characters that are all from the same Unicode script.  How-
+       ever, because some scripts are commonly used together, and because some
+       diacritical  and  other marks are used with multiple scripts, it is not
+       that simple.
+
+       Every Unicode character has a Script property, mostly with a value cor-
+       responding to the name of a script, such as Latin, Greek, or  Cyrillic.
+       There are also three special values:
+
+       "Unknown" is used for code points that have not been assigned, and also
+       for  the surrogate code points. In the PCRE2 32-bit library, characters
+       whose code points are greater  than  the  Unicode  maximum  (U+10FFFF),
+       which  are  accessible  only  in non-UTF mode, are assigned the Unknown
+       script.
+
+       "Common" is used for characters that are used with many scripts.  These
+       include  punctuation,  emoji,  mathematical, musical, and currency sym-
+       bols, and the ASCII digits 0 to 9.
+
+       "Inherited" is used for characters such as diacritical marks that  mod-
+       ify a previous character. These are considered to take on the script of
+       the character that they modify.
+
+       Some  Inherited characters are used with many scripts, but many of them
+       are only normally used with a small number  of  scripts.  For  example,
+       U+102E0 (Coptic Epact thousands mark) is used only with Arabic and Cop-
+       tic.  In  order  to  make it possible to check this, a Unicode property
+       called Script Extension exists. Its value is a list of scripts that ap-
+       ply to the character. For the majority of characters, the list contains
+       just one script, the same one as  the  Script  property.  However,  for
+       characters  such  as  U+102E0 more than one Script is listed. There are
+       also some Common characters that have a single,  non-Common  script  in
+       their Script Extension list.
+
+       The next section describes the basic rules for deciding whether a given
+       string  of  characters  is  a script run. Note, however, that there are
+       some special cases involving the Chinese Han script, and an  additional
+       constraint  for  decimal  digits.  These are covered in subsequent sec-
+       tions.
+
+   Basic script run rules
+
+       A string that is less than two characters long is a script run. This is
+       the only case in which an Unknown character can be  part  of  a  script
+       run.  Longer strings are checked using only the Script Extensions prop-
+       erty, not the basic Script property.
+
+       If a character's Script Extension property is the single value  "Inher-
+       ited", it is always accepted as part of a script run. This is also true
+       for  the  property  "Common", subject to the checking of decimal digits
+       described below. All the remaining characters in a script run must have
+       at least one script in common in their Script Extension lists. In  set-
+       theoretic terminology, the intersection of all the sets of scripts must
+       not be empty.
+
+       A  simple example is an Internet name such as "google.com". The letters
+       are all in the Latin script, and the dot is Common, so this string is a
+       script run.  However, the Cyrillic letter "o" looks exactly the same as
+       the Latin "o"; a string that looks the same, but with Cyrillic "o"s  is
+       not a script run.
+
+       More  interesting examples involve characters with more than one script
+       in their Script Extension. Consider the following characters:
+
+         U+060C  Arabic comma
+         U+06D4  Arabic full stop
+
+       The first has the Script Extension list Arabic, Hanifi  Rohingya,  Syr-
+       iac,  and  Thaana; the second has just Arabic and Hanifi Rohingya. Both
+       of them could appear in script runs of  either  Arabic  or  Hanifi  Ro-
+       hingya.  The  first  could also appear in Syriac or Thaana script runs,
+       but the second could not.
+
+   The Chinese Han script
+
+       The Chinese Han script is  commonly  used  in  conjunction  with  other
+       scripts  for  writing certain languages. Japanese uses the Hiragana and
+       Katakana scripts together with Han; Korean uses Hangul  and  Han;  Tai-
+       wanese  Mandarin  uses  Bopomofo  and Han. These three combinations are
+       treated as special cases when checking script runs and are, in  effect,
+       "virtual  scripts".  Thus,  a script run may contain a mixture of Hira-
+       gana, Katakana, and Han, or a mixture of Hangul and Han, or  a  mixture
+       of  Bopomofo  and  Han,  but  not, for example, a mixture of Hangul and
+       Bopomofo and Han. PCRE2 (like Perl) follows Unicode's  Technical  Stan-
+       dard   39   ("Unicode   Security   Mechanisms",  http://unicode.org/re-
+       ports/tr39/) in allowing such mixtures.
+
+   Decimal digits
+
+       Unicode contains many sets of 10 decimal digits in  different  scripts,
+       and  some  scripts  (including the Common script) contain more than one
+       set. Some of these decimal digits them are  visually  indistinguishable
+       from  the  common  ASCII digits. In addition to the script checking de-
+       scribed above, if a script run contains any decimal digits,  they  must
+       all come from the same set of 10 adjacent characters.
+
+
+VALIDITY OF UTF STRINGS
+
+       When  the  PCRE2_UTF  option is set, the strings passed as patterns and
+       subjects are (by default) checked for validity on entry to the relevant
+       functions. If an invalid UTF string is passed, a negative error code is
+       returned. The code unit offset to the offending character  can  be  ex-
+       tracted  from  the  match  data block by calling pcre2_get_startchar(),
+       which is used for this purpose after a UTF error.
+
+       In some situations, you may already know that your strings  are  valid,
+       and  therefore  want  to  skip these checks in order to improve perfor-
+       mance, for example in the case of a long subject string that  is  being
+       scanned  repeatedly.   If you set the PCRE2_NO_UTF_CHECK option at com-
+       pile time or at match time, PCRE2 assumes that the pattern  or  subject
+       it is given (respectively) contains only valid UTF code unit sequences.
+
+       If  you  pass an invalid UTF string when PCRE2_NO_UTF_CHECK is set, the
+       result is undefined and your program may crash or loop indefinitely  or
+       give  incorrect  results.  There is, however, one mode of matching that
+       can handle invalid UTF subject strings.  This  is  enabled  by  passing
+       PCRE2_MATCH_INVALID_UTF  to  pcre2_compile()  and is discussed below in
+       the next section. The  rest  of  this  section  covers  the  case  when
+       PCRE2_MATCH_INVALID_UTF is not set.
+
+       Passing  PCRE2_NO_UTF_CHECK  to  pcre2_compile()  just disables the UTF
+       check for the pattern; it does not also apply to  subject  strings.  If
+       you  want  to disable the check for a subject string you must pass this
+       same option to pcre2_match() or pcre2_dfa_match().
+
+       UTF-16 and UTF-32 strings can indicate their endianness by special code
+       knows as a byte-order mark (BOM). The PCRE2  functions  do  not  handle
+       this, expecting strings to be in host byte order.
+
+       Unless  PCRE2_NO_UTF_CHECK  is  set, a UTF string is checked before any
+       other  processing  takes  place.  In  the  case  of  pcre2_match()  and
+       pcre2_dfa_match()  calls  with a non-zero starting offset, the check is
+       applied only to that part of the subject that could be inspected during
+       matching, and there is a check that the starting offset points  to  the
+       first  code  unit of a character or to the end of the subject. If there
+       are no lookbehind assertions in the pattern, the check  starts  at  the
+       starting  offset.   Otherwise,  it  starts at the length of the longest
+       lookbehind before the starting offset, or at the start of  the  subject
+       if  there are not that many characters before the starting offset. Note
+       that the sequences \b and \B are one-character lookbehinds.
+
+       In addition to checking the format of the string, there is a  check  to
+       ensure that all code points lie in the range U+0 to U+10FFFF, excluding
+       the  surrogate  area. The so-called "non-character" code points are not
+       excluded because Unicode corrigendum #9 makes it clear that they should
+       not be.
+
+       Characters in the "Surrogate Area" of Unicode are reserved for  use  by
+       UTF-16,  where they are used in pairs to encode code points with values
+       greater than 0xFFFF. The code points that are encoded by  UTF-16  pairs
+       are  available  independently  in  the  UTF-8 and UTF-32 encodings. (In
+       other words, the whole surrogate thing is a fudge for UTF-16 which  un-
+       fortunately messes up UTF-8 and UTF-32.)
+
+       Setting  PCRE2_NO_UTF_CHECK  at compile time does not disable the error
+       that is given if an escape sequence for an invalid Unicode  code  point
+       is  encountered  in  the pattern. If you want to allow escape sequences
+       such as \x{d800} (a surrogate code point) you  can  set  the  PCRE2_EX-
+       TRA_ALLOW_SURROGATE_ESCAPES  extra  option.  However,  this is possible
+       only in UTF-8 and UTF-32 modes, because these  values  are  not  repre-
+       sentable in UTF-16.
+
+   Errors in UTF-8 strings
+
+       The following negative error codes are given for invalid UTF-8 strings:
+
+         PCRE2_ERROR_UTF8_ERR1
+         PCRE2_ERROR_UTF8_ERR2
+         PCRE2_ERROR_UTF8_ERR3
+         PCRE2_ERROR_UTF8_ERR4
+         PCRE2_ERROR_UTF8_ERR5
+
+       The  string  ends  with a truncated UTF-8 character; the code specifies

+       checked first; hence the possibility of 4 or 5 missing bytes.

+         PCRE2_ERROR_UTF8_ERR14
+
+       A  3-byte  character  has  a  value in the range 0xd800 to 0xdfff; this
+       range of code points are reserved by RFC 3629 for use with UTF-16,  and

+
+       A  2-, 3-, 4-, 5-, or 6-byte character is "overlong", that is, it codes
+       for a value that can be represented by fewer bytes, which  is  invalid.

+         PCRE2_ERROR_UTF8_ERR20
+
+       The two most significant bits of the first byte of a character have the
+       binary value 0b10 (that is, the most significant bit is 1 and the  sec-
+       ond  is  0). Such a byte can only validly occur as the second or subse-
+       quent byte of a multi-byte character.
+
+         PCRE2_ERROR_UTF8_ERR21
+
+       The first byte of a character has the value 0xfe or 0xff. These  values

+         PCRE2_ERROR_UTF32_ERR2  Code point is greater than 0x10ffff
+
+
+MATCHING IN INVALID UTF STRINGS
+
+       You can run pattern matches on subject strings that may contain invalid
+       UTF  sequences  if  you  call  pcre2_compile() with the PCRE2_MATCH_IN-
+       VALID_UTF option. This is supported  by  pcre2_match(),  including  JIT
+       matching, but not by pcre2_dfa_match(). When PCRE2_MATCH_INVALID_UTF is
+       set,  it  forces  PCRE2_UTF  to be set as well. Note, however, that the
+       pattern itself must be a valid UTF string.
+
+       If you do not set PCRE2_MATCH_INVALID_UTF when  calling  pcre2_compile,
+       and  you  are  not  certain that your subject strings are valid UTF se-
+       quences, you should not make  use  of  the  JIT  "fast  path"  function
+       pcre2_jit_match()  because it bypasses sanity checks, including the one
+       for UTF validity. An invalid string may cause undefined behaviour,  in-
+       cluding looping, crashing, or giving the wrong answer.
+
+       Setting  PCRE2_MATCH_INVALID_UTF  does  not affect what pcre2_compile()
+       generates, but if pcre2_jit_compile() is subsequently called,  it  does
+       generate different code. If JIT is not used, the option affects the be-
+       haviour of the interpretive code in pcre2_match(). When PCRE2_MATCH_IN-
+       VALID_UTF  is  set  at  compile  time, PCRE2_NO_UTF_CHECK is ignored at
+       match time.
+
+       In this mode, an invalid  code  unit  sequence  in  the  subject  never
+       matches  any  pattern  item.  It  does not match dot, it does not match
+       \p{Any}, it does not even match negative items such as [^X]. A  lookbe-
+       hind  assertion fails if it encounters an invalid sequence while moving
+       the current point backwards. In other words, an invalid UTF  code  unit
+       sequence acts as a barrier which no match can cross.
+
+       You can also think of this as the subject being split up into fragments
+       of  valid UTF, delimited internally by invalid code unit sequences. The
+       pattern is matched fragment by fragment. The  result  of  a  successful
+       match,  however,  is  given  as code unit offsets in the entire subject
+       string in the usual way. There are a few points to consider:
+
+       The internal boundaries are not interpreted as the beginnings  or  ends
+       of  lines  and  so  do not match circumflex or dollar characters in the
+       pattern.
+
+       If pcre2_match() is called with an offset that  points  to  an  invalid
+       UTF-sequence,  that  sequence  is  skipped, and the match starts at the
+       next valid UTF character, or the end of the subject.
+
+       At internal fragment boundaries, \b and \B behave in the same way as at
+       the beginning and end of the subject. For example, a sequence  such  as
+       \bWORD\b  would match an instance of WORD that is surrounded by invalid
+       UTF code units.
+
+       Using PCRE2_MATCH_INVALID_UTF, an application can run matches on  arbi-
+       trary  data,  knowing  that  any  matched strings that are returned are
+       valid UTF. This can be useful when searching for UTF text in executable
+       or other binary files.
+
+       Note, however, that the  16-bit  and  32-bit  PCRE2  libraries  process
+       strings  as  sequences of uint16_t or uint32_t code points. They cannot
+       find valid UTF sequences within an arbitrary  string  of  bytes  unless
+       such sequences are suitably aligned.

+.B int pcre2_callout_enumerate(const pcre2_code *\fIcode\fP,
+.B "  int (*\fIcallback\fP)(pcre2_callout_enumerate_block *, void *),"
+.B "  void *\fIcallout_data\fP);"
+.fi
+.
+.SH DESCRIPTION
+.rs
+.sp
+This function scans a compiled regular expression and calls the \fIcallback()\fP
+function for each callout within the pattern. The yield of the function is zero
+for success and non-zero otherwise. The arguments are:
+.sp
+  \fIcode\fP           Points to the compiled pattern
+  \fIcallback\fP       The callback function
+  \fIcallout_data\fP   User data that is passed to the callback
+.sp
+The \fIcallback()\fP function is passed a pointer to a data block containing
+the following fields (not necessarily in this order):
+.sp
+  uint32_t   \fIversion\fP                Block version number
+  uint32_t   \fIcallout_number\fP         Number for numbered callouts
+  PCRE2_SIZE \fIpattern_position\fP       Offset to next item in pattern
+  PCRE2_SIZE \fInext_item_length\fP       Length of next item in pattern
+  PCRE2_SIZE \fIcallout_string_offset\fP  Offset to string within pattern
+  PCRE2_SIZE \fIcallout_string_length\fP  Length of callout string
+  PCRE2_SPTR \fIcallout_string\fP         Points to callout string or is NULL
+.sp
+The second argument passed to the \fBcallback()\fP function is the callout data
+that was passed to \fBpcre2_callout_enumerate()\fP. The \fBcallback()\fP
+function must return zero for success. Any other value causes the pattern scan
+to stop, with the value being passed back as the result of
+\fBpcre2_callout_enumerate()\fP.

+This function compiles a regular expression pattern into an internal form. Its
+arguments are:
+.sp
+  \fIpattern\fP       A string containing expression to be compiled
+  \fIlength\fP        The length of the string or PCRE2_ZERO_TERMINATED

+.sp
+The length of the pattern and any error offset that is returned are in code
+units, not characters. A NULL pattern with zero length is treated as an empty
+string. A compile context is needed only if you want to provide custom memory
+allocation functions, or to provide an external function for system stack size
+checking (see \fBpcre2_set_compile_recursion_guard()\fP), or to change one or
+more of these parameters:
+.sp
+  What \eR matches (Unicode newlines, or CR, LF, CRLF only);
+  PCRE2's character tables;
+  The newline character sequence;
+  The compile time nested parentheses limit;
+  The maximum pattern length (in code units) that is allowed;
+  The additional options bits.
+.sp
+The primary option bits are:
+.sp
+  PCRE2_ANCHORED           Force pattern anchoring
+  PCRE2_ALLOW_EMPTY_CLASS  Allow empty classes

+  PCRE2_AUTO_CALLOUT       Compile automatic callouts
+  PCRE2_CASELESS           Do caseless matching
+  PCRE2_DOLLAR_ENDONLY     $ not to match newline at end
+  PCRE2_DOTALL             . matches anything including NL
+  PCRE2_DUPNAMES           Allow duplicate names for subpatterns
+  PCRE2_ENDANCHORED        Pattern can match only at end of subject
+  PCRE2_EXTENDED           Ignore white space and # comments
+  PCRE2_FIRSTLINE          Force matching to be before newline
+  PCRE2_LITERAL            Pattern characters are all literal
+  PCRE2_MATCH_INVALID_UTF  Enable support for matching invalid UTF
+  PCRE2_MATCH_UNSET_BACKREF  Match unset backreferences
+  PCRE2_MULTILINE          ^ and $ match newlines within data
+  PCRE2_NEVER_BACKSLASH_C  Lock out the use of \eC in patterns

+.SH DESCRIPTION
+.rs
+.sp
+This function makes it possible for a client program to find out which optional
+features are available in the version of the PCRE2 library it is using. The
+arguments are as follows:
+.sp
+  \fIwhat\fP     A code specifying what information is required
+  \fIwhere\fP    Points to where to put the information
+.sp
+If \fIwhere\fP is NULL, the function returns the amount of memory needed for
+the requested information. When the information is a string, the value is in
+code units; for other types of data it is in bytes.
+.P
+If \fBwhere\fP is not NULL, for PCRE2_CONFIG_JITTARGET,
+PCRE2_CONFIG_UNICODE_VERSION, and PCRE2_CONFIG_VERSION it must point to a
+buffer that is large enough to hold the string. For all other codes it must
+point to a uint32_t integer variable. The available codes are:
+.sp
+  PCRE2_CONFIG_BSR             Indicates what \eR matches by default:
+                                 PCRE2_BSR_UNICODE

+.\" JOIN
+  PCRE2_CONFIG_JITTARGET       Information (a string) about the target
+                                 architecture for the JIT compiler
+  PCRE2_CONFIG_LINKSIZE        Configured internal link size (2, 3, 4)

+.
+.SH DESCRIPTION
+.rs
+.sp
+This function matches a compiled regular expression against a given subject
+string, using an alternative matching algorithm that scans the subject string
+just once (except when processing lookaround assertions). This function is
+\fInot\fP Perl-compatible (the Perl-compatible matching function is
+\fBpcre2_match()\fP). The arguments for this function are:
+.sp
+  \fIcode\fP         Points to the compiled pattern
+  \fIsubject\fP      Points to the subject string
+  \fIlength\fP       Length of the subject string
+  \fIstartoffset\fP  Offset in the subject at which to start matching
+  \fIoptions\fP      Option bits
+  \fImatch_data\fP   Points to a match data block, for results
+  \fImcontext\fP     Points to a match context, or is NULL
+  \fIworkspace\fP    Points to a vector of ints used as working space
+  \fIwscount\fP      Number of elements in the vector
+.sp
+The size of output vector needed to contain all the results depends on the
+number of simultaneous matches, not on the number of parentheses in the
+pattern. Using \fBpcre2_match_data_create_from_pattern()\fP to create the match
+data block is therefore not advisable when using this function.
+.P
+A match context is needed only if you want to set up a callout function or
+specify the heap limit or the match or the recursion depth limits. The
+\fIlength\fP and \fIstartoffset\fP values are code units, not characters. The
+options are:
+.sp
+  PCRE2_ANCHORED          Match only at the first position
+  PCRE2_COPY_MATCHED_SUBJECT
+                          On success, make a private subject copy
+  PCRE2_ENDANCHORED       Pattern can match only at end of subject
+  PCRE2_NOTBOL            Subject is not the beginning of a line
+  PCRE2_NOTEOL            Subject is not the end of a line
+  PCRE2_NOTEMPTY          An empty string is not a valid match
+.\" JOIN
+  PCRE2_NOTEMPTY_ATSTART  An empty string at the start of the subject
+                           is not a valid match

+option is deprecated and may be removed in the future.
+.P
+The yield of the function is 0 for success, or a negative error code otherwise.
+In particular, PCRE2_ERROR_JIT_BADOPTION is returned if JIT is not supported or

+.
+.SH DESCRIPTION
+.rs
+.sp
+This function matches a compiled regular expression that has been successfully
+processed by the JIT compiler against a given subject string, using a matching
+algorithm that is similar to Perl's. It is a "fast path" interface to JIT, and
+it bypasses some of the sanity checks that \fBpcre2_match()\fP applies.
+.P
+In UTF mode, the subject string is not checked for UTF validity. Unless
+PCRE2_MATCH_INVALID_UTF was set when the pattern was compiled, passing an
+invalid UTF string results in undefined behaviour. Your program may crash or
+loop or give wrong results. In the absence of PCRE2_MATCH_INVALID_UTF you
+should only call \fBpcre2_jit_match()\fP in UTF mode if you are sure the
+subject is valid.
+.P
+The arguments for \fBpcre2_jit_match()\fP are exactly the same as for
+.\" HREF
+\fBpcre2_match()\fP,
+.\"
+except that the subject string must be specified with a length;
+PCRE2_ZERO_TERMINATED is not supported.
+.P
+The supported options are PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY,
+PCRE2_NOTEMPTY_ATSTART, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. Unsupported
+options are ignored.
+.P
+The return values are the same as for \fBpcre2_match()\fP plus
+PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial or complete) is requested
+that was not compiled. For details of partial matching, see the

+.SH DESCRIPTION
+.rs
+.sp
+This function provides control over the memory used by JIT as a run-time stack
+when \fBpcre2_match()\fP or \fBpcre2_jit_match()\fP is called with a pattern
+that has been successfully processed by the JIT compiler. The information that
+determines which stack is used is put into a match context that is subsequently
+passed to a matching function. The arguments of this function are:
+.sp
+  mcontext       a pointer to a match context
+  callback       a callback function
+  callback_data  a JIT stack or a value to be passed to the callback
+.P
+If \fImcontext\fP is NULL, the function returns immediately, without doing
+anything.
+.P
+If \fIcallback\fP is NULL and \fIcallback_data\fP is NULL, an internal 32KiB
+block on the machine stack is used.
+.P
+If \fIcallback\fP is NULL and \fIcallback_data\fP is not NULL,
+\fIcallback_data\fP must be a valid JIT stack, the result of calling
+\fBpcre2_jit_stack_create()\fP.
+.P
+If \fIcallback\fP not NULL, it is called with \fIcallback_data\fP as an
+argument at the start of matching, in order to set up a JIT stack. If the
+result is NULL, the internal 32KiB stack is used; otherwise the return value
+must be a valid JIT stack, the result of calling
+\fBpcre2_jit_stack_create()\fP.
+.P
+You may safely use the same JIT stack for multiple patterns, as long as they
+are all matched in the same thread. In a multithread application, each thread
+must use its own JIT stack. For more details, see the

+This function is used to create a stack for use by the code compiled by the JIT

+allocation. The result can be passed to the JIT run-time code by calling
+\fBpcre2_jit_stack_assign()\fP to associate the stack with a compiled pattern,
+which can then be processed by \fBpcre2_match()\fP or \fBpcre2_jit_match()\fP.
+A maximum stack size of 512KiB to 1MiB should be more than enough for any
+pattern. If the stack couldn't be allocated or the values passed were not
+reasonable, NULL will be returned. For more details, see the

+.SH DESCRIPTION
+.rs
+.sp
+This function creates a new match data block for holding the result of a match.
+The first argument points to a compiled pattern. The number of capturing
+parentheses within the pattern is used to compute the number of pairs of
+offsets that are required in the match data block. These form the "output
+vector" (ovector) within the match data block, and are used to identify the
+matched string and any captured substrings when matching with
+\fBpcre2_match()\fP. If you are using \fBpcre2_dfa_match()\fP, which uses the
+output vector in a different way, you should use \fBpcre2_match_data_create()\fP
+instead of this function.
+.P
+The second argument points to a general context, for custom memory management,
+or is NULL to use the same memory allocator as was used for the compiled
+pattern. The result of the function is NULL if the memory for the block could
+not be obtained.

+.
+.SH DESCRIPTION
+.rs
+.sp
+This function is part of an experimental set of pattern conversion functions.
+It converts a foreign pattern (for example, a glob) into a PCRE2 regular
+expression pattern. Its arguments are:
+.sp
+  \fIpattern\fP     The foreign pattern
+  \fIlength\fP      The length of the input pattern or PCRE2_ZERO_TERMINATED
+  \fIoptions\fP     Option bits
+  \fIbuffer\fP      Pointer to pointer to output buffer, or NULL
+  \fIblength\fP     Pointer to output length field
+  \fIcvcontext\fP   Pointer to a convert context or NULL
+.sp
+The length of the converted pattern (excluding the terminating zero) is
+returned via \fIblength\fP. If \fIbuffer\fP is NULL, the function just returns
+the output length. If \fIbuffer\fP points to a NULL pointer, heap memory is
+obtained for the converted pattern, using the allocator in the context if
+present (or else \fBmalloc()\fP), and the field pointed to by \fIbuffer\fP is
+updated. If \fIbuffer\fP points to a non-NULL field, that must point to a
+buffer whose size is in the variable pointed to by \fIblength\fP. This value is
+updated.
+.P
+The option bits are:
+.sp
+  PCRE2_CONVERT_UTF                     Input is UTF
+  PCRE2_CONVERT_NO_UTF_CHECK            Do not check UTF validity
+  PCRE2_CONVERT_POSIX_BASIC             Convert POSIX basic pattern
+  PCRE2_CONVERT_POSIX_EXTENDED          Convert POSIX extended pattern
+  PCRE2_CONVERT_GLOB                    ) Convert
+  PCRE2_CONVERT_GLOB_NO_WILD_SEPARATOR  )   various types
+  PCRE2_CONVERT_GLOB_NO_STARSTAR        )     of glob
+.sp
+The return value from \fBpcre2_pattern_convert()\fP is zero on success or a
+non-zero PCRE2 error code.
+.P
+The pattern conversion functions are described in the
+.\" HREF

+.rs
+.sp
+This function decodes a serialized set of compiled patterns back into a list of

+.sp
+The \fIbytes\fP argument must point to a block of data that was originally

+.SH DESCRIPTION
+.rs
+.sp
+This function encodes a list of compiled patterns into a byte stream that can
+be saved on disc or elsewhere. Note that this is not an abstract format like
+Java or .NET. Conversion of the byte stream back into usable compiled patterns
+can only happen on a host that is running the same version of PCRE2, with the
+same code unit width, and the host must also have the same endianness, pointer
+width and PCRE2_SIZE type. The arguments for \fBpcre2_serialize_encode()\fP
+are:

+  \fIcodes\fP             pointer to a vector containing the list
+  \fInumber_of_codes\fP   number of slots in the vector
+  \fIserialized_bytes\fP  set to point to the serialized byte stream
+  \fIserialized_size\fP   set to the number of bytes in the byte stream
+  \fIgcontext\fP          pointer to a general context or NULL
+.sp
+The context argument is used to obtain memory for the byte stream. When the
+serialized data is no longer needed, it must be freed by calling
+\fBpcre2_serialize_free()\fP. The yield of the function is the number of
+serialized patterns, or one of the following negative error codes:

+  PCRE2_ERROR_NULL         an argument other than \fIgcontext\fP is NULL
+.sp

+parenthesis nesting, and the second is user data that is supplied when the
+function is set up. The callout function should return zero if all is well, or
+non-zero to force an error. This feature is provided so that applications can
+check the available system stack space, in order to avoid running out. The
+result of \fBpcre2_set_compile_recursion_guard()\fP is always zero.

+.
+.
+.SH "PCRE2 8-BIT, 16-BIT, AND 32-BIT LIBRARIES"
+.rs
+.sp
+There are three PCRE2 libraries, supporting 8-bit, 16-bit, and 32-bit code
+units, respectively. However, there is just one header file, \fBpcre2.h\fP.
+This contains the function prototypes and other definitions for all three
+libraries. One, two, or all three can be installed simultaneously. On Unix-like
+systems the libraries are called \fBlibpcre2-8\fP, \fBlibpcre2-16\fP, and
+\fBlibpcre2-32\fP, and they can also co-exist with the original PCRE libraries.
+Every PCRE2 function comes in three different forms, one for each library, for
+example:
+.sp
+  \fBpcre2_compile_8()\fP
+  \fBpcre2_compile_16()\fP
+  \fBpcre2_compile_32()\fP
+.sp
+There are also three different sets of data types:
+.sp
+  \fBPCRE2_UCHAR8, PCRE2_UCHAR16, PCRE2_UCHAR32\fP
+  \fBPCRE2_SPTR8,  PCRE2_SPTR16,  PCRE2_SPTR32\fP
+.sp
+The UCHAR types define unsigned code units of the appropriate widths.
+For example, PCRE2_UCHAR16 is usually defined as `uint16_t'.
+The SPTR types are pointers to constants of the equivalent UCHAR types,
+that is, they are pointers to vectors of unsigned code units.
+.P
+Character strings are passed to a PCRE2 library as sequences of unsigned
+integers in code units of the appropriate width. The length of a string may
+be given as a number of code units, or the string may be specified as
+zero-terminated.
+.P
+Many applications use only one code unit width. For their convenience, macros
+are defined whose names are the generic forms such as \fBpcre2_compile()\fP and
+PCRE2_SPTR. These macros use the value of the macro PCRE2_CODE_UNIT_WIDTH to
+generate the appropriate width-specific function and macro names.
+PCRE2_CODE_UNIT_WIDTH is not defined by default. An application must define it
+to be 8, 16, or 32 before including \fBpcre2.h\fP in order to make use of the
+generic names.
+.P
+Applications that use more than one code unit width can be linked with more
+than one PCRE2 library, but must define PCRE2_CODE_UNIT_WIDTH to be 0 before
+including \fBpcre2.h\fP, and then use the real function names. Any code that is
+to be included in an environment where the value of PCRE2_CODE_UNIT_WIDTH is
+unknown should also use the real function names. (Unfortunately, it is not
+possible in C code to save and restore the value of a macro.)
+.P
+If PCRE2_CODE_UNIT_WIDTH is not defined before including \fBpcre2.h\fP, a
+compiler error occurs.
+.P
+When using multiple libraries in an application, you must take care when
+processing any particular pattern to use only functions from a single library.
+For example, if you want to run a match using a pattern that was compiled with
+\fBpcre2_compile_16()\fP, you must do so with \fBpcre2_match_16()\fP, not
+\fBpcre2_match_8()\fP or \fBpcre2_match_32()\fP.
+.P
+In the function summaries above, and in the rest of this document and other
+PCRE2 documents, functions and data types are described using their generic
+names, without the _8, _16, or _32 suffix.
+.
+.
+.SH "PCRE2 API OVERVIEW"
+.rs
+.sp
+PCRE2 has its own native API, which is described in this document. There are
+also some wrapper functions for the 8-bit library that correspond to the
+POSIX regular expression API, but they do not give access to all the
+functionality of PCRE2 and they are not thread-safe. They are described in the
+.\" HREF
+\fBpcre2posix\fP
+.\"
+documentation. Both these APIs define a set of C function calls.
+.P
+The native API C data types, function prototypes, option values, and error
+codes are defined in the header file \fBpcre2.h\fP, which also contains
+definitions of PCRE2_MAJOR and PCRE2_MINOR, the major and minor release numbers
+for the library. Applications can use these to include support for different
+releases of PCRE2.
+.P
+In a Windows environment, if you want to statically link an application program
+against a non-dll PCRE2 library, you must define PCRE2_STATIC before including
+\fBpcre2.h\fP.
+.P
+The functions \fBpcre2_compile()\fP and \fBpcre2_match()\fP are used for
+compiling and matching regular expressions in a Perl-compatible manner. A
+sample program that demonstrates the simplest way of using them is provided in
+the file called \fIpcre2demo.c\fP in the PCRE2 source distribution. A listing
+of this program is given in the
+.\" HREF
+\fBpcre2demo\fP
+.\"
+documentation, and the
+.\" HREF
+\fBpcre2sample\fP
+.\"
+documentation describes how to compile and run it.
+.P
+The compiling and matching functions recognize various options that are passed
+as bits in an options argument. There are also some more complicated parameters
+such as custom memory management functions and resource limits that are passed
+in "contexts" (which are just memory blocks, described below). Simple
+applications do not need to make use of contexts.
+.P
+Just-in-time (JIT) compiler support is an optional feature of PCRE2 that can be
+built in appropriate hardware environments. It greatly speeds up the matching
+performance of many patterns. Programs can request that it be used if
+available by calling \fBpcre2_jit_compile()\fP after a pattern has been
+successfully compiled by \fBpcre2_compile()\fP. This does nothing if JIT
+support is not available.
+.P
+More complicated programs might need to make use of the specialist functions
+\fBpcre2_jit_stack_create()\fP, \fBpcre2_jit_stack_free()\fP, and
+\fBpcre2_jit_stack_assign()\fP in order to control the JIT code's memory usage.
+.P
+JIT matching is automatically used by \fBpcre2_match()\fP if it is available,
+unless the PCRE2_NO_JIT option is set. There is also a direct interface for JIT
+matching, which gives improved performance at the expense of less sanity
+checking. The JIT-specific functions are discussed in the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation.
+.P
+A second matching function, \fBpcre2_dfa_match()\fP, which is not
+Perl-compatible, is also provided. This uses a different algorithm for the
+matching. The alternative algorithm finds all possible matches (at a given
+point in the subject), and scans the subject just once (unless there are
+lookaround assertions). However, this algorithm does not return captured
+substrings. A description of the two matching algorithms and their advantages
+and disadvantages is given in the
+.\" HREF
+\fBpcre2matching\fP
+.\"
+documentation. There is no JIT support for \fBpcre2_dfa_match()\fP.
+.P
+In addition to the main compiling and matching functions, there are convenience
+functions for extracting captured substrings from a subject string that has
+been matched by \fBpcre2_match()\fP. They are:
+.sp
+  \fBpcre2_substring_copy_byname()\fP
+  \fBpcre2_substring_copy_bynumber()\fP
+  \fBpcre2_substring_get_byname()\fP
+  \fBpcre2_substring_get_bynumber()\fP
+  \fBpcre2_substring_list_get()\fP
+  \fBpcre2_substring_length_byname()\fP
+  \fBpcre2_substring_length_bynumber()\fP
+  \fBpcre2_substring_nametable_scan()\fP
+  \fBpcre2_substring_number_from_name()\fP
+.sp
+\fBpcre2_substring_free()\fP and \fBpcre2_substring_list_free()\fP are also
+provided, to free memory used for extracted strings. If either of these
+functions is called with a NULL argument, the function returns immediately
+without doing anything.
+.P
+The function \fBpcre2_substitute()\fP can be called to match a pattern and
+return a copy of the subject string with substitutions for parts that were
+matched.
+.P
+Functions whose names begin with \fBpcre2_serialize_\fP are used for saving
+compiled patterns on disc or elsewhere, and reloading them later.
+.P
+Finally, there are functions for finding out information about a compiled
+pattern (\fBpcre2_pattern_info()\fP) and about the configuration with which
+PCRE2 was built (\fBpcre2_config()\fP).
+.P
+Functions with names ending with \fB_free()\fP are used for freeing memory
+blocks of various sorts. In all cases, if one of these functions is called with
+a NULL argument, it does nothing.
+.
+.
+.SH "STRING LENGTHS AND OFFSETS"
+.rs
+.sp
+The PCRE2 API uses string lengths and offsets into strings of code units in
+several places. These values are always of type PCRE2_SIZE, which is an
+unsigned integer type, currently always defined as \fIsize_t\fP. The largest
+value that can be stored in such a type (that is ~(PCRE2_SIZE)0) is reserved
+as a special indicator for zero-terminated strings and unset offsets.
+Therefore, the longest string that can be handled is one less than this
+maximum. Note that string lengths are always given in code units. Only in the
+8-bit library is such a length the same as the number of bytes in the string.
+.
+.
+.\" HTML 
+.SH NEWLINES
+.rs
+.sp
+PCRE2 supports five different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, or any
+Unicode newline sequence. The Unicode newline sequences are the three just
+mentioned, plus the single characters VT (vertical tab, U+000B), FF (form feed,
+U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and PS
+(paragraph separator, U+2029).
+.P
+Each of the first three conventions is used by at least one operating system as
+its standard newline sequence. When PCRE2 is built, a default can be specified.
+If it is not, the default is set to LF, which is the Unix standard. However,
+the newline convention can be changed by an application when calling
+\fBpcre2_compile()\fP, or it can be specified by special text at the start of
+the pattern itself; this overrides any other settings. See the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+page for details of the special character sequences.
+.P
+In the PCRE2 documentation the word "newline" is used to mean "the character or
+pair of characters that indicate a line break". The choice of newline
+convention affects the handling of the dot, circumflex, and dollar
+metacharacters, the handling of #-comments in /x mode, and, when CRLF is a
+recognized line ending sequence, the match position advancement for a
+non-anchored pattern. There is more detail about this in the
+.\" HTML 
+.\" 
+section on \fBpcre2_match()\fP options
+.\"
+below.
+.P
+The choice of newline convention does not affect the interpretation of
+the \en or \er escape sequences, nor does it affect what \eR matches; this has
+its own separate convention.
+.
+.
+.SH MULTITHREADING
+.rs
+.sp
+In a multithreaded application it is important to keep thread-specific data
+separate from data that can be shared between threads. The PCRE2 library code
+itself is thread-safe: it contains no static or global variables. The API is
+designed to be fairly simple for non-threaded applications while at the same
+time ensuring that multithreaded applications can use it.
+.P
+There are several different blocks of data that are used to pass information
+between the application and the PCRE2 libraries.
+.
+.
+.SS "The compiled pattern"
+.rs
+.sp
+A pointer to the compiled form of a pattern is returned to the user when
+\fBpcre2_compile()\fP is successful. The data in the compiled pattern is fixed,
+and does not change when the pattern is matched. Therefore, it is thread-safe,
+that is, the same compiled pattern can be used by more than one thread
+simultaneously. For example, an application can compile all its patterns at the
+start, before forking off multiple threads that use them. However, if the
+just-in-time (JIT) optimization feature is being used, it needs separate memory
+stack areas for each thread. See the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation for more details.
+.P
+In a more complicated situation, where patterns are compiled only when they are
+first needed, but are still shared between threads, pointers to compiled
+patterns must be protected from simultaneous writing by multiple threads. This
+is somewhat tricky to do correctly. If you know that writing to a pointer is
+atomic in your environment, you can use logic like this:
+.sp
+  Get a read-only (shared) lock (mutex) for pointer
+  if (pointer == NULL)
+    {
+    Get a write (unique) lock for pointer
+    if (pointer == NULL) pointer = pcre2_compile(...
+    }
+  Release the lock
+  Use pointer in pcre2_match()
+.sp
+Of course, testing for compilation errors should also be included in the code.
+.P
+The reason for checking the pointer a second time is as follows: Several
+threads may have acquired the shared lock and tested the pointer for being
+NULL, but only one of them will be given the write lock, with the rest kept
+waiting. The winning thread will compile the pattern and store the result.
+After this thread releases the write lock, another thread will get it, and if
+it does not retest pointer for being NULL, will recompile the pattern and
+overwrite the pointer, creating a memory leak and possibly causing other
+issues.
+.P
+In an environment where writing to a pointer may not be atomic, the above logic
+is not sufficient. The thread that is doing the compiling may be descheduled
+after writing only part of the pointer, which could cause other threads to use
+an invalid value. Instead of checking the pointer itself, a separate "pointer
+is valid" flag (that can be updated atomically) must be used:
+.sp
+  Get a read-only (shared) lock (mutex) for pointer
+  if (!pointer_is_valid)
+    {
+    Get a write (unique) lock for pointer
+    if (!pointer_is_valid)
+      {
+      pointer = pcre2_compile(...
+      pointer_is_valid = TRUE
+      }
+    }
+  Release the lock
+  Use pointer in pcre2_match()
+.sp
+If JIT is being used, but the JIT compilation is not being done immediately
+(perhaps waiting to see if the pattern is used often enough), similar logic is
+required. JIT compilation updates a value within the compiled code block, so a
+thread must gain unique write access to the pointer before calling
+\fBpcre2_jit_compile()\fP. Alternatively, \fBpcre2_code_copy()\fP or
+\fBpcre2_code_copy_with_tables()\fP can be used to obtain a private copy of the
+compiled code before calling the JIT compiler.
+.
+.
+.SS "Context blocks"
+.rs
+.sp
+The next main section below introduces the idea of "contexts" in which PCRE2
+functions are called. A context is nothing more than a collection of parameters
+that control the way PCRE2 operates. Grouping a number of parameters together
+in a context is a convenient way of passing them to a PCRE2 function without
+using lots of arguments. The parameters that are stored in contexts are in some
+sense "advanced features" of the API. Many straightforward applications will
+not need to use contexts.
+.P
+In a multithreaded application, if the parameters in a context are values that
+are never changed, the same context can be used by all the threads. However, if
+any thread needs to change any value in a context, it must make its own
+thread-specific copy.
+.
+.
+.SS "Match blocks"
+.rs
+.sp
+The matching functions need a block of memory for storing the results of a
+match. This includes details of what was matched, as well as additional
+information such as the name of a (*MARK) setting. Each thread must provide its
+own copy of this memory.
+.
+.
+.SH "PCRE2 CONTEXTS"
+.rs
+.sp
+Some PCRE2 functions have a lot of parameters, many of which are used only by
+specialist applications, for example, those that use custom memory management
+or non-standard character tables. To keep function argument lists at a
+reasonable size, and at the same time to keep the API extensible, "uncommon"
+parameters are passed to certain functions in a \fBcontext\fP instead of
+directly. A context is just a block of memory that holds the parameter values.
+Applications that do not need to adjust any of the context parameters can pass
+NULL when a context pointer is required.
+.P
+There are three different types of context: a general context that is relevant
+for several PCRE2 operations, a compile-time context, and a match-time context.
+.
+.
+.SS "The general context"
+.rs
+.sp
+At present, this context just contains pointers to (and data for) external
+memory management functions that are called from several places in the PCRE2
+library. The context is named `general' rather than specifically `memory'
+because in future other fields may be added. If you do not want to supply your
+own custom memory management functions, you do not need to bother with a
+general context. A general context is created by:
+.sp
+.nf
+.B pcre2_general_context *pcre2_general_context_create(
+.B "  void *(*\fIprivate_malloc\fP)(PCRE2_SIZE, void *),"
+.B "  void (*\fIprivate_free\fP)(void *, void *), void *\fImemory_data\fP);"
+.fi
+.sp
+The two function pointers specify custom memory management functions, whose
+prototypes are:
+.sp
+  \fBvoid *private_malloc(PCRE2_SIZE, void *);\fP
+  \fBvoid  private_free(void *, void *);\fP
+.sp
+Whenever code in PCRE2 calls these functions, the final argument is the value
+of \fImemory_data\fP. Either of the first two arguments of the creation
+function may be NULL, in which case the system memory management functions
+\fImalloc()\fP and \fIfree()\fP are used. (This is not currently useful, as
+there are no other fields in a general context, but in future there might be.)
+The \fIprivate_malloc()\fP function is used (if supplied) to obtain memory for
+storing the context, and all three values are saved as part of the context.
+.P
+Whenever PCRE2 creates a data block of any kind, the block contains a pointer
+to the \fIfree()\fP function that matches the \fImalloc()\fP function that was
+used. When the time comes to free the block, this function is called.
+.P
+A general context can be copied by calling:
+.sp
+.nf
+.B pcre2_general_context *pcre2_general_context_copy(
+.B "  pcre2_general_context *\fIgcontext\fP);"
+.fi
+.sp
+The memory used for a general context should be freed by calling:
+.sp
+.nf
+.B void pcre2_general_context_free(pcre2_general_context *\fIgcontext\fP);
+.fi
+.sp
+If this function is passed a NULL argument, it returns immediately without
+doing anything.
+.
+.
+.\" HTML 
+.SS "The compile context"
+.rs
+.sp
+A compile context is required if you want to provide an external function for
+stack checking during compilation or to change the default values of any of the
+following compile-time parameters:
+.sp
+  What \eR matches (Unicode newlines or CR, LF, CRLF only)
+  PCRE2's character tables
+  The newline character sequence
+  The compile time nested parentheses limit
+  The maximum length of the pattern string
+  The extra options bits (none set by default)
+.sp
+A compile context is also required if you are using custom memory management.
+If none of these apply, just pass NULL as the context argument of
+\fIpcre2_compile()\fP.

+ending sequence. The value is used by the JIT compiler and by the two
+interpreted matching functions, \fIpcre2_match()\fP and
+\fIpcre2_dfa_match()\fP.
+.sp
+.nf
+.B int pcre2_set_character_tables(pcre2_compile_context *\fIccontext\fP,

+PCRE2_NEWLINE_LF (linefeed only), PCRE2_NEWLINE_CRLF (the two-character
+sequence CR followed by LF), PCRE2_NEWLINE_ANYCRLF (any of the above),
+PCRE2_NEWLINE_ANY (any Unicode newline sequence), or PCRE2_NEWLINE_NUL (the

+.P
+When a pattern is compiled with the PCRE2_EXTENDED or PCRE2_EXTENDED_MORE

+.sp
+The \fImatch_limit\fP parameter provides a means of preventing PCRE2 from using
+up too many computing resources when processing patterns that are not going to
+match, but which have a very large number of possibilities in their search
+trees. The classic example is a pattern that uses nested unlimited repeats.
+.P
+There is an internal counter in \fBpcre2_match()\fP that is incremented each
+time round its main matching loop. If this value reaches the match limit,
+\fBpcre2_match()\fP returns the negative value PCRE2_ERROR_MATCHLIMIT. This has
+the effect of limiting the amount of backtracking that can take place. For
+patterns that are not anchored, the count restarts from zero for each position
+in the subject string. This limit also applies to \fBpcre2_dfa_match()\fP,
+though the counting is done in a different way.
+.P
+When \fBpcre2_match()\fP is called with a pattern that was successfully
+processed by \fBpcre2_jit_compile()\fP, the way in which matching is executed
+is entirely different. However, there is still the possibility of runaway
+matching that goes on for a very long time, and so the \fImatch_limit\fP value
+is also used in this case (but in a different way) to limit how long the
+matching can continue.
+.P
+The default value for the limit can be set when PCRE2 is built; the default is
+10 million, which handles all but the most extreme cases. A value for the match
+limit may also be supplied by an item at the start of a pattern of the form
+.sp

+.B "  uint32_t \fIvalue\fP);"
+.fi
+.sp
+This parameter limits the depth of nested backtracking in \fBpcre2_match()\fP.
+Each time a nested backtracking point is passed, a new memory frame is used
+to remember the state of matching at that point. Thus, this parameter
+indirectly limits the amount of memory that is used in a match. However,
+because the size of each memory frame depends on the number of capturing
+parentheses, the actual memory limit varies from pattern to pattern. This limit
+was more useful in versions before 10.30, where function recursion was used for
+backtracking.
+.P
+The depth limit is not relevant, and is ignored, when matching is done using
+JIT compiled code. However, it is supported by \fBpcre2_dfa_match()\fP, which
+uses it to limit the depth of nested internal recursive function calls that
+implement atomic groups, lookaround assertions, and pattern recursions. This
+limits, indirectly, the amount of system stack that is used. It was more useful
+in versions before 10.32, when stack memory was used for local workspace
+vectors for recursive function calls. From version 10.32, only local variables
+are allocated on the stack and as each call uses only a few hundred bytes, even
+a small stack can support quite a lot of recursion.
+.P
+If the depth of internal recursive function calls is great enough, local
+workspace vectors are allocated on the heap from version 10.32 onwards, so the
+depth limit also indirectly limits the amount of heap memory that is used. A
+recursive pattern such as /(.(?2))((?1)|)/, when matched to a very long string
+using \fBpcre2_dfa_match()\fP, can use a great deal of memory. However, it is
+probably better to limit heap usage directly by calling
+\fBpcre2_set_heap_limit()\fP.
+.P
+The default value for the depth limit can be set when PCRE2 is built; if it is
+not, the default is set to the same value as the default for the match limit.
+If the limit is exceeded, \fBpcre2_match()\fP or \fBpcre2_dfa_match()\fP
+returns PCRE2_ERROR_DEPTHLIMIT. A value for the depth limit may also be
+supplied by an item at the start of a pattern of the form
+.sp
+  (*LIMIT_DEPTH=ddd)

+where ddd is a decimal number. However, such a setting is ignored unless ddd is

+and the 2-bit and 4-bit indicate 16-bit and 32-bit support, respectively.
+.sp
+  PCRE2_CONFIG_DEPTHLIMIT
+.sp
+The output is a uint32_t integer that gives the default limit for the depth of
+nested backtracking in \fBpcre2_match()\fP or the depth of nested recursions,
+lookarounds, and atomic groups in \fBpcre2_dfa_match()\fP. Further details are
+given with \fBpcre2_set_depth_limit()\fP above.
+.sp
+  PCRE2_CONFIG_HEAPLIMIT
+.sp
+The output is a uint32_t integer that gives, in kibibytes, the default limit
+for the amount of heap memory used by \fBpcre2_match()\fP or
+\fBpcre2_dfa_match()\fP. Further details are given with
+\fBpcre2_set_heap_limit()\fP above.
+.sp
+  PCRE2_CONFIG_JIT
+.sp
+The output is a uint32_t integer that is set to one if support for just-in-time
+compiling is included in the library; otherwise it is set to zero. Note that
+having the support in the library does not guarantee that JIT will be used for
+any given match. See the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation for more details.
+.sp
+  PCRE2_CONFIG_JITTARGET
+.sp
+The \fIwhere\fP argument should point to a buffer that is at least 48 code
+units long. (The exact length required can be found by calling
+\fBpcre2_config()\fP with \fBwhere\fP set to NULL.) The buffer is filled with a
+string that contains the name of the architecture for which the JIT compiler is
+configured, for example "x86 32bit (little endian + unaligned)". If JIT support
+is not available, PCRE2_ERROR_BADOPTION is returned, otherwise the number of
+code units used is returned. This is the length of the string, plus one unit
+for the terminating zero.
+.sp
+  PCRE2_CONFIG_LINKSIZE
+.sp
+The output is a uint32_t integer that contains the number of bytes used for
+internal linkage in compiled regular expressions. When PCRE2 is configured, the
+value can be set to 2, 3, or 4, with the default being 2. This is the value
+that is returned by \fBpcre2_config()\fP. However, when the 16-bit library is
+compiled, a value of 3 is rounded up to 4, and when the 32-bit library is
+compiled, internal linkages always use 4 bytes, so the configured value is not
+relevant.
+.P
+The default value of 2 for the 8-bit and 16-bit libraries is sufficient for all
+but the most massive patterns, since it allows the size of the compiled pattern
+to be up to 65535 code units. Larger values allow larger regular expressions to
+be compiled by those two libraries, but at the expense of slower matching.
+.sp
+  PCRE2_CONFIG_MATCHLIMIT
+.sp
+The output is a uint32_t integer that gives the default match limit for
+\fBpcre2_match()\fP. Further details are given with
+\fBpcre2_set_match_limit()\fP above.
+.sp
+  PCRE2_CONFIG_NEWLINE
+.sp
+The output is a uint32_t integer whose value specifies the default character
+sequence that is recognized as meaning "newline". The values are:
+.sp
+  PCRE2_NEWLINE_CR       Carriage return (CR)
+  PCRE2_NEWLINE_LF       Linefeed (LF)
+  PCRE2_NEWLINE_CRLF     Carriage return, linefeed (CRLF)
+  PCRE2_NEWLINE_ANY      Any Unicode line ending
+  PCRE2_NEWLINE_ANYCRLF  Any of CR, LF, or CRLF
+  PCRE2_NEWLINE_NUL      The NUL character (binary zero)
+.sp
+The default should normally correspond to the standard sequence for your
+operating system.
+.sp
+  PCRE2_CONFIG_NEVER_BACKSLASH_C
+.sp
+The output is a uint32_t integer that is set to one if the use of \eC was
+permanently disabled when PCRE2 was built; otherwise it is set to zero.
+.sp
+  PCRE2_CONFIG_PARENSLIMIT
+.sp
+The output is a uint32_t integer that gives the maximum depth of nesting
+of parentheses (of any kind) in a pattern. This limit is imposed to cap the
+amount of system stack used when a pattern is compiled. It is specified when
+PCRE2 is built; the default is 250. This limit does not take into account the
+stack that may already be used by the calling application. For finer control
+over compilation stack usage, see \fBpcre2_set_compile_recursion_guard()\fP.
+.sp
+  PCRE2_CONFIG_STACKRECURSE
+.sp
+This parameter is obsolete and should not be used in new code. The output is a
+uint32_t integer that is always set to zero.
+.sp
+  PCRE2_CONFIG_TABLES_LENGTH
+.sp
+The output is a uint32_t integer that gives the length of PCRE2's character
+processing tables in bytes. For details of these tables see the
+.\" HTML 
+.\" 
+section on locale support
+.\"
+below.
+.sp
+  PCRE2_CONFIG_UNICODE_VERSION
+.sp
+The \fIwhere\fP argument should point to a buffer that is at least 24 code
+units long. (The exact length required can be found by calling
+\fBpcre2_config()\fP with \fBwhere\fP set to NULL.) If PCRE2 has been compiled
+without Unicode support, the buffer is filled with the text "Unicode not
+supported". Otherwise, the Unicode version string (for example, "8.0.0") is
+inserted. The number of code units used is returned. This is the length of the
+string plus one unit for the terminating zero.
+.sp
+  PCRE2_CONFIG_UNICODE
+.sp
+The output is a uint32_t integer that is set to one if Unicode support is
+available; otherwise it is set to zero. Unicode support implies UTF support.
+.sp
+  PCRE2_CONFIG_VERSION
+.sp
+The \fIwhere\fP argument should point to a buffer that is at least 24 code
+units long. (The exact length required can be found by calling
+\fBpcre2_config()\fP with \fBwhere\fP set to NULL.) The buffer is filled with
+the PCRE2 version string, zero-terminated. The number of code units used is
+returned. This is the length of the string plus one unit for the terminating
+zero.

+.P
+The \fBpcre2_compile()\fP function compiles a pattern into an internal form.
+The pattern is defined by a pointer to a string of code units and a length in
+code units. If the pattern is zero-terminated, the length can be specified as
+PCRE2_ZERO_TERMINATED. A NULL pattern pointer with a length of zero is treated
+as an empty string (NULL with a non-zero length causes an error return). The
+function returns a pointer to a block of memory that contains the compiled
+pattern and related data, or NULL if an error occurred.
+.P
+If the compile context argument \fIccontext\fP is NULL, memory for the compiled
+pattern is obtained by calling \fBmalloc()\fP. Otherwise, it is obtained from
+the same memory function that was used for the compile context. The caller must
+free the memory by calling \fBpcre2_code_free()\fP when it is no longer needed.
+If \fBpcre2_code_free()\fP is called with a NULL argument, it returns
+immediately, without doing anything.
+.P
+The function \fBpcre2_code_copy()\fP makes a copy of the compiled code in new
+memory, using the same memory allocator as was used for the original. However,
+if the code has been processed by the JIT compiler (see
+.\" HTML 
+.\" 
+below),
+.\"
+the JIT information cannot be copied (because it is position-dependent).
+The new copy can initially be used only for non-JIT matching, though it can be
+passed to \fBpcre2_jit_compile()\fP if required. If \fBpcre2_code_copy()\fP is
+called with a NULL argument, it returns NULL.
+.P
+The \fBpcre2_code_copy()\fP function provides a way for individual threads in a
+multithreaded application to acquire a private copy of shared compiled code.
+However, it does not make a copy of the character tables used by the compiled
+pattern; the new pattern code points to the same tables as the original code.
+(See
+.\" HTML 
+.\" 
+"Locale Support"
+.\"
+below for details of these character tables.) In many applications the same
+tables are used throughout, so this behaviour is appropriate. Nevertheless,
+there are occasions when a copy of a compiled pattern and the relevant tables
+are needed. The \fBpcre2_code_copy_with_tables()\fP provides this facility.
+Copies of both the code and the tables are made, with the new code pointing to
+the new tables. The memory for the new tables is automatically freed when
+\fBpcre2_code_free()\fP is called for the new copy of the compiled code. If
+\fBpcre2_code_copy_with_tables()\fP is called with a NULL argument, it returns
+NULL.
+.P
+NOTE: When one of the matching functions is called, pointers to the compiled
+pattern and the subject string are set in the match data block so that they can
+be referenced by the substring extraction functions after a successful match.
+After running a match, you must not free a compiled pattern or a subject string
+until after all operations on the
+.\" HTML 
+.\" 
+match data block
+.\"
+have taken place, unless, in the case of the subject string, you have used the
+PCRE2_COPY_MATCHED_SUBJECT option, which is described in the section entitled
+"Option bits for \fBpcre2_match()\fP"
+.\" HTML 
+.\" 
+below.
+.\"
+.P
+The \fIoptions\fP argument for \fBpcre2_compile()\fP contains various bit
+settings that affect the compilation. It should be zero if none of them are
+required. The available options are described below. Some of them (in
+particular, those that are compatible with Perl, but some others as well) can
+also be set and unset from within the pattern (see the detailed description in
+the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation).
+.P
+For those options that can be different in different parts of the pattern, the
+contents of the \fIoptions\fP argument specifies their settings at the start of
+compilation. The PCRE2_ANCHORED, PCRE2_ENDANCHORED, and PCRE2_NO_UTF_CHECK
+options can be set at the time of matching as well as at compile time.
+.P
+Some additional options and less frequently required compile-time parameters
+(for example, the newline setting) can be provided in a compile context (as
+described
+.\" HTML 
+.\" 
+above).
+.\"
+.P
+If \fIerrorcode\fP or \fIerroroffset\fP is NULL, \fBpcre2_compile()\fP returns
+NULL immediately. Otherwise, the variables to which these point are set to an
+error code and an offset (number of code units) within the pattern,
+respectively, when \fBpcre2_compile()\fP returns NULL because a compilation
+error has occurred.
+.P
+There are nearly 100 positive error codes that \fBpcre2_compile()\fP may return
+if it finds an error in the pattern. There are also some negative error codes
+that are used for invalid UTF strings when validity checking is in force. These
+are the same as given by \fBpcre2_match()\fP and \fBpcre2_dfa_match()\fP, and
+are described in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+documentation. There is no separate documentation for the positive error codes,
+because the textual error messages that are obtained by calling the
+\fBpcre2_get_error_message()\fP function (see "Obtaining a textual error
+message"
+.\" HTML 
+.\" 
+below)
+.\"
+should be self-explanatory. Macro names starting with PCRE2_ERROR_ are defined
+for both positive and negative error codes in \fBpcre2.h\fP. When compilation
+is successful \fIerrorcode\fP is set to a value that returns the message "no
+error" if passed to \fBpcre2_get_error_message()\fP.
+.P
+The value returned in \fIerroroffset\fP is an indication of where in the
+pattern an error occurred. When there is no error, zero is returned. A non-zero
+value is not necessarily the furthest point in the pattern that was read. For
+example, after the error "lookbehind assertion is not fixed length", the error
+offset points to the start of the failing assertion. For an invalid UTF-8 or
+UTF-16 string, the offset is that of the first code unit of the failing
+character.
+.P
+Some errors are not detected until the whole pattern has been scanned; in these
+cases, the offset passed back is the length of the pattern. Note that the
+offset is in code units, not characters, even in a UTF mode. It may sometimes
+point into the middle of a UTF-8 or UTF-16 character.
+.P
+This code fragment shows a typical straightforward call to
+\fBpcre2_compile()\fP:
+.sp
+  pcre2_code *re;
+  PCRE2_SIZE erroffset;
+  int errorcode;
+  re = pcre2_compile(
+    "^A.*Z",                /* the pattern */

+    0,                      /* default options */
+    &errorcode,             /* for error code */
+    &erroffset,             /* for error offset */
+    NULL);                  /* no compile context */
+.sp
+.
+.
+.SS "Main compile options"
+.rs
+.sp
+The following names for option bits are defined in the \fBpcre2.h\fP header
+file:
+.sp
+  PCRE2_ANCHORED
+.sp
+If this bit is set, the pattern is forced to be "anchored", that is, it is
+constrained to match only at the first matching point in the string that is
+being searched (the "subject string"). This effect can also be achieved by
+appropriate constructs in the pattern itself, which is the only way to do it in
+Perl.
+.sp
+  PCRE2_ALLOW_EMPTY_CLASS
+.sp
+By default, for compatibility with Perl, a closing square bracket that
+immediately follows an opening one is treated as a data character for the
+class. When PCRE2_ALLOW_EMPTY_CLASS is set, it terminates the class, which
+therefore contains no characters and so can never match.
+.sp
+  PCRE2_ALT_BSUX
+.sp
+This option request alternative handling of three escape sequences, which
+makes PCRE2's behaviour more like ECMAscript (aka JavaScript). When it is set:
+.P
+(1) \eU matches an upper case "U" character; by default \eU causes a compile
+time error (Perl uses \eU to upper case subsequent characters).
+.P
+(2) \eu matches a lower case "u" character unless it is followed by four
+hexadecimal digits, in which case the hexadecimal number defines the code point
+to match. By default, \eu causes a compile time error (Perl uses it to upper
+case the following character).
+.P
+(3) \ex matches a lower case "x" character unless it is followed by two
+hexadecimal digits, in which case the hexadecimal number defines the code point
+to match. By default, as in Perl, a hexadecimal number is always expected after
+\ex, but it may have zero, one, or two digits (so, for example, \exz matches a
+binary zero character followed by z).
+.P
+ECMAscript 6 added additional functionality to \eu. This can be accessed using
+the PCRE2_EXTRA_ALT_BSUX extra option (see "Extra compile options"
+.\" HTML 
+.\" 
+below).
+.\"
+Note that this alternative escape handling applies only to patterns. Neither of
+these options affects the processing of replacement strings passed to
+\fBpcre2_substitute()\fP.
+.sp
+  PCRE2_ALT_CIRCUMFLEX
+.sp
+In multiline mode (when PCRE2_MULTILINE is set), the circumflex metacharacter
+matches at the start of the subject (unless PCRE2_NOTBOL is set), and also
+after any internal newline. However, it does not match after a newline at the
+end of the subject, for compatibility with Perl. If you want a multiline
+circumflex also to match after a terminating newline, you must set
+PCRE2_ALT_CIRCUMFLEX.
+.sp
+  PCRE2_ALT_VERBNAMES
+.sp
+By default, for compatibility with Perl, the name in any verb sequence such as
+(*MARK:NAME) is any sequence of characters that does not include a closing
+parenthesis. The name is not processed in any way, and it is not possible to
+include a closing parenthesis in the name. However, if the PCRE2_ALT_VERBNAMES
+option is set, normal backslash processing is applied to verb names and only an
+unescaped closing parenthesis terminates the name. A closing parenthesis can be
+included in a name either as \e) or between \eQ and \eE. If the PCRE2_EXTENDED
+or PCRE2_EXTENDED_MORE option is set with PCRE2_ALT_VERBNAMES, unescaped
+whitespace in verb names is skipped and #-comments are recognized, exactly as
+in the rest of the pattern.
+.sp
+  PCRE2_AUTO_CALLOUT
+.sp
+If this bit is set, \fBpcre2_compile()\fP automatically inserts callout items,
+all with number 255, before each pattern item, except immediately before or
+after an explicit callout in the pattern. For discussion of the callout
+facility, see the
+.\" HREF
+\fBpcre2callout\fP
+.\"
+documentation.
+.sp
+  PCRE2_CASELESS
+.sp
+If this bit is set, letters in the pattern match both upper and lower case
+letters in the subject. It is equivalent to Perl's /i option, and it can be
+changed within a pattern by a (?i) option setting. If either PCRE2_UTF or
+PCRE2_UCP is set, Unicode properties are used for all characters with more than
+one other case, and for all characters whose code points are greater than
+U+007F. Note that there are two ASCII characters, K and S, that, in addition to
+their lower case ASCII equivalents, are case-equivalent with U+212A (Kelvin
+sign) and U+017F (long S) respectively. If you do not want this case
+equivalence, you can suppress it by setting PCRE2_EXTRA_CASELESS_RESTRICT.
+.P
+For lower valued characters with only one other case, a lookup table is used
+for speed. When neither PCRE2_UTF nor PCRE2_UCP is set, a lookup table is used
+for all code points less than 256, and higher code points (available only in
+16-bit or 32-bit mode) are treated as not having another case.
+.sp
+  PCRE2_DOLLAR_ENDONLY
+.sp
+If this bit is set, a dollar metacharacter in the pattern matches only at the
+end of the subject string. Without this option, a dollar also matches
+immediately before a newline at the end of the string (but not before any other
+newlines). The PCRE2_DOLLAR_ENDONLY option is ignored if PCRE2_MULTILINE is
+set. There is no equivalent to this option in Perl, and no way to set it within
+a pattern.
+.sp
+  PCRE2_DOTALL
+.sp
+If this bit is set, a dot metacharacter in the pattern matches any character,
+including one that indicates a newline. However, it only ever matches one
+character, even if newlines are coded as CRLF. Without this option, a dot does
+not match when the current position in the subject is at a newline. This option
+is equivalent to Perl's /s option, and it can be changed within a pattern by a
+(?s) option setting. A negative class such as [^a] always matches newline
+characters, and the \eN escape sequence always matches a non-newline character,
+independent of the setting of PCRE2_DOTALL.
+.sp
+  PCRE2_DUPNAMES
+.sp
+If this bit is set, names used to identify capture groups need not be unique.
+This can be helpful for certain types of pattern when it is known that only one
+instance of the named group can ever be matched. There are more details of
+named capture groups below; see also the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation.
+.sp
+  PCRE2_ENDANCHORED
+.sp
+If this bit is set, the end of any pattern match must be right at the end of
+the string being searched (the "subject string"). If the pattern match
+succeeds by reaching (*ACCEPT), but does not reach the end of the subject, the
+match fails at the current starting point. For unanchored patterns, a new match
+is then tried at the next starting point. However, if the match succeeds by
+reaching the end of the pattern, but not the end of the subject, backtracking
+occurs and an alternative match may be found. Consider these two patterns:
+.sp
+  .(*ACCEPT)|..
+  .|..
+.sp
+If matched against "abc" with PCRE2_ENDANCHORED set, the first matches "c"
+whereas the second matches "bc". The effect of PCRE2_ENDANCHORED can also be
+achieved by appropriate constructs in the pattern itself, which is the only way
+to do it in Perl.
+.P
+For DFA matching with \fBpcre2_dfa_match()\fP, PCRE2_ENDANCHORED applies only
+to the first (that is, the longest) matched string. Other parallel matches,
+which are necessarily substrings of the first one, must obviously end before
+the end of the subject.
+.sp
+  PCRE2_EXTENDED
+.sp
+If this bit is set, most white space characters in the pattern are totally
+ignored except when escaped, inside a character class, or inside a \eQ...\eE
+sequence. However, white space is not allowed within sequences such as (?> that
+introduce various parenthesized groups, nor within numerical quantifiers such
+as {1,3}. Ignorable white space is permitted between an item and a following
+quantifier and between a quantifier and a following + that indicates
+possessiveness. PCRE2_EXTENDED is equivalent to Perl's /x option, and it can be
+changed within a pattern by a (?x) option setting.
+.P
+When PCRE2 is compiled without Unicode support, PCRE2_EXTENDED recognizes as
+white space only those characters with code points less than 256 that are
+flagged as white space in its low-character table. The table is normally
+created by
+.\" HREF
+\fBpcre2_maketables()\fP,
+.\"
+which uses the \fBisspace()\fP function to identify space characters. In most
+ASCII environments, the relevant characters are those with code points 0x0009
+(tab), 0x000A (linefeed), 0x000B (vertical tab), 0x000C (formfeed), 0x000D
+(carriage return), and 0x0020 (space).
+.P
+When PCRE2 is compiled with Unicode support, in addition to these characters,
+five more Unicode "Pattern White Space" characters are recognized by
+PCRE2_EXTENDED. These are U+0085 (next line), U+200E (left-to-right mark),
+U+200F (right-to-left mark), U+2028 (line separator), and U+2029 (paragraph
+separator). This set of characters is the same as recognized by Perl's /x
+option. Note that the horizontal and vertical space characters that are matched
+by the \eh and \ev escapes in patterns are a much bigger set.
+.P
+As well as ignoring most white space, PCRE2_EXTENDED also causes characters
+between an unescaped # outside a character class and the next newline,
+inclusive, to be ignored, which makes it possible to include comments inside
+complicated patterns. Note that the end of this type of comment is a literal
+newline sequence in the pattern; escape sequences that happen to represent a
+newline do not count.
+.P
+Which characters are interpreted as newlines can be specified by a setting in
+the compile context that is passed to \fBpcre2_compile()\fP or by a special
+sequence at the start of the pattern, as described in the section entitled
+.\" HTML 
+.\" 
+"Newline conventions"
+.\"
+in the \fBpcre2pattern\fP documentation. A default is defined when PCRE2 is
+built.
+.sp
+  PCRE2_EXTENDED_MORE
+.sp
+This option has the effect of PCRE2_EXTENDED, but, in addition, unescaped space
+and horizontal tab characters are ignored inside a character class. Note: only
+these two characters are ignored, not the full set of pattern white space
+characters that are ignored outside a character class. PCRE2_EXTENDED_MORE is
+equivalent to Perl's /xx option, and it can be changed within a pattern by a
+(?xx) option setting.
+.sp
+  PCRE2_FIRSTLINE
+.sp
+If this option is set, the start of an unanchored pattern match must be before
+or at the first newline in the subject string following the start of matching,
+though the matched text may continue over the newline. If \fIstartoffset\fP is
+non-zero, the limiting newline is not necessarily the first newline in the
+subject. For example, if the subject string is "abc\enxyz" (where \en
+represents a single-character newline) a pattern match for "yz" succeeds with
+PCRE2_FIRSTLINE if \fIstartoffset\fP is greater than 3. See also
+PCRE2_USE_OFFSET_LIMIT, which provides a more general limiting facility. If
+PCRE2_FIRSTLINE is set with an offset limit, a match must occur in the first
+line and also within the offset limit. In other words, whichever limit comes
+first is used. This option has no effect for anchored patterns.
+.sp
+  PCRE2_LITERAL
+.sp
+If this option is set, all meta-characters in the pattern are disabled, and it
+is treated as a literal string. Matching literal strings with a regular
+expression engine is not the most efficient way of doing it. If you are doing a
+lot of literal matching and are worried about efficiency, you should consider
+using other approaches. The only other main options that are allowed with
+PCRE2_LITERAL are: PCRE2_ANCHORED, PCRE2_ENDANCHORED, PCRE2_AUTO_CALLOUT,
+PCRE2_CASELESS, PCRE2_FIRSTLINE, PCRE2_MATCH_INVALID_UTF,
+PCRE2_NO_START_OPTIMIZE, PCRE2_NO_UTF_CHECK, PCRE2_UTF, and
+PCRE2_USE_OFFSET_LIMIT. The extra options PCRE2_EXTRA_MATCH_LINE and
+PCRE2_EXTRA_MATCH_WORD are also supported. Any other options cause an error.
+.sp
+  PCRE2_MATCH_INVALID_UTF
+.sp
+This option forces PCRE2_UTF (see below) and also enables support for matching
+by \fBpcre2_match()\fP in subject strings that contain invalid UTF sequences.
+Note, however, that the 16-bit and 32-bit PCRE2 libraries process strings as
+sequences of uint16_t or uint32_t code points. They cannot find valid UTF
+sequences within an arbitrary string of bytes unless such sequences are
+suitably aligned. This facility is not supported for DFA matching. For details,
+see the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+documentation.
+.sp
+  PCRE2_MATCH_UNSET_BACKREF
+.sp
+If this option is set, a backreference to an unset capture group matches an
+empty string (by default this causes the current matching alternative to fail).
+A pattern such as (\e1)(a) succeeds when this option is set (assuming it can
+find an "a" in the subject), whereas it fails by default, for Perl
+compatibility. Setting this option makes PCRE2 behave more like ECMAscript (aka
+JavaScript).
+.sp
+  PCRE2_MULTILINE
+.sp
+By default, for the purposes of matching "start of line" and "end of line",
+PCRE2 treats the subject string as consisting of a single line of characters,
+even if it actually contains newlines. The "start of line" metacharacter (^)
+matches only at the start of the string, and the "end of line" metacharacter
+($) matches only at the end of the string, or before a terminating newline
+(except when PCRE2_DOLLAR_ENDONLY is set). Note, however, that unless
+PCRE2_DOTALL is set, the "any character" metacharacter (.) does not match at a
+newline. This behaviour (for ^, $, and dot) is the same as Perl.
+.P
+When PCRE2_MULTILINE it is set, the "start of line" and "end of line"
+constructs match immediately following or immediately before internal newlines
+in the subject string, respectively, as well as at the very start and end. This
+is equivalent to Perl's /m option, and it can be changed within a pattern by a
+(?m) option setting. Note that the "start of line" metacharacter does not match
+after a newline at the end of the subject, for compatibility with Perl.
+However, you can change this by setting the PCRE2_ALT_CIRCUMFLEX option. If
+there are no newlines in a subject string, or no occurrences of ^ or $ in a
+pattern, setting PCRE2_MULTILINE has no effect.
+.sp
+  PCRE2_NEVER_BACKSLASH_C
+.sp
+This option locks out the use of \eC in the pattern that is being compiled.
+This escape can cause unpredictable behaviour in UTF-8 or UTF-16 modes, because
+it may leave the current matching point in the middle of a multi-code-unit
+character. This option may be useful in applications that process patterns from
+external sources. Note that there is also a build-time option that permanently
+locks out the use of \eC.
+.sp
+  PCRE2_NEVER_UCP
+.sp
+This option locks out the use of Unicode properties for handling \eB, \eb, \eD,
+\ed, \eS, \es, \eW, \ew, and some of the POSIX character classes, as described
+for the PCRE2_UCP option below. In particular, it prevents the creator of the
+pattern from enabling this facility by starting the pattern with (*UCP). This
+option may be useful in applications that process patterns from external
+sources. The option combination PCRE_UCP and PCRE_NEVER_UCP causes an error.
+.sp
+  PCRE2_NEVER_UTF
+.sp
+This option locks out interpretation of the pattern as UTF-8, UTF-16, or
+UTF-32, depending on which library is in use. In particular, it prevents the
+creator of the pattern from switching to UTF interpretation by starting the
+pattern with (*UTF). This option may be useful in applications that process
+patterns from external sources. The combination of PCRE2_UTF and
+PCRE2_NEVER_UTF causes an error.
+.sp
+  PCRE2_NO_AUTO_CAPTURE
+.sp
+If this option is set, it disables the use of numbered capturing parentheses in
+the pattern. Any opening parenthesis that is not followed by ? behaves as if it
+were followed by ?: but named parentheses can still be used for capturing (and
+they acquire numbers in the usual way). This is the same as Perl's /n option.
+Note that, when this option is set, references to capture groups
+(backreferences or recursion/subroutine calls) may only refer to named groups,
+though the reference can be by name or by number.
+.sp
+  PCRE2_NO_AUTO_POSSESS
+.sp
+If this option is set, it disables "auto-possessification", which is an
+optimization that, for example, turns a+b into a++b in order to avoid
+backtracks into a+ that can never be successful. However, if callouts are in
+use, auto-possessification means that some callouts are never taken. You can
+set this option if you want the matching functions to do a full unoptimized
+search and run all the callouts, but it is mainly provided for testing
+purposes.
+.sp
+  PCRE2_NO_DOTSTAR_ANCHOR
+.sp
+If this option is set, it disables an optimization that is applied when .* is
+the first significant item in a top-level branch of a pattern, and all the
+other branches also start with .* or with \eA or \eG or ^. The optimization is
+automatically disabled for .* if it is inside an atomic group or a capture
+group that is the subject of a backreference, or if the pattern contains
+(*PRUNE) or (*SKIP). When the optimization is not disabled, such a pattern is
+automatically anchored if PCRE2_DOTALL is set for all the .* items and
+PCRE2_MULTILINE is not set for any ^ items. Otherwise, the fact that any match
+must start either at the start of the subject or following a newline is
+remembered. Like other optimizations, this can cause callouts to be skipped.
+.sp
+  PCRE2_NO_START_OPTIMIZE
+.sp
+This is an option whose main effect is at matching time. It does not change
+what \fBpcre2_compile()\fP generates, but it does affect the output of the JIT
+compiler.
+.P
+There are a number of optimizations that may occur at the start of a match, in
+order to speed up the process. For example, if it is known that an unanchored
+match must start with a specific code unit value, the matching code searches
+the subject for that value, and fails immediately if it cannot find it, without
+actually running the main matching function. This means that a special item
+such as (*COMMIT) at the start of a pattern is not considered until after a
+suitable starting point for the match has been found. Also, when callouts or
+(*MARK) items are in use, these "start-up" optimizations can cause them to be
+skipped if the pattern is never actually used. The start-up optimizations are
+in effect a pre-scan of the subject that takes place before the pattern is run.
+.P
+The PCRE2_NO_START_OPTIMIZE option disables the start-up optimizations,
+possibly causing performance to suffer, but ensuring that in cases where the
+result is "no match", the callouts do occur, and that items such as (*COMMIT)
+and (*MARK) are considered at every possible starting position in the subject
+string.
+.P
+Setting PCRE2_NO_START_OPTIMIZE may change the outcome of a matching operation.
+Consider the pattern
+.sp
+  (*COMMIT)ABC
+.sp
+When this is compiled, PCRE2 records the fact that a match must start with the
+character "A". Suppose the subject string is "DEFABC". The start-up
+optimization scans along the subject, finds "A" and runs the first match
+attempt from there. The (*COMMIT) item means that the pattern must match the
+current starting position, which in this case, it does. However, if the same
+match is run with PCRE2_NO_START_OPTIMIZE set, the initial scan along the
+subject string does not happen. The first match attempt is run starting from
+"D" and when this fails, (*COMMIT) prevents any further matches being tried, so
+the overall result is "no match".
+.P
+As another start-up optimization makes use of a minimum length for a matching
+subject, which is recorded when possible. Consider the pattern
+.sp
+  (*MARK:1)B(*MARK:2)(X|Y)
+.sp
+The minimum length for a match is two characters. If the subject is "XXBB", the
+"starting character" optimization skips "XX", then tries to match "BB", which
+is long enough. In the process, (*MARK:2) is encountered and remembered. When
+the match attempt fails, the next "B" is found, but there is only one character
+left, so there are no more attempts, and "no match" is returned with the "last
+mark seen" set to "2". If NO_START_OPTIMIZE is set, however, matches are tried
+at every possible starting position, including at the end of the subject, where
+(*MARK:1) is encountered, but there is no "B", so the "last mark seen" that is
+returned is "1". In this case, the optimizations do not affect the overall
+match result, which is still "no match", but they do affect the auxiliary
+information that is returned.
+.sp
+  PCRE2_NO_UTF_CHECK
+.sp
+When PCRE2_UTF is set, the validity of the pattern as a UTF string is
+automatically checked. There are discussions about the validity of
+.\" HTML 
+.\" 
+UTF-8 strings,
+.\"
+.\" HTML 
+.\" 
+UTF-16 strings,
+.\"
+and
+.\" HTML 
+.\" 
+UTF-32 strings
+.\"
+in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+document. If an invalid UTF sequence is found, \fBpcre2_compile()\fP returns a
+negative error code.
+.P
+If you know that your pattern is a valid UTF string, and you want to skip this
+check for performance reasons, you can set the PCRE2_NO_UTF_CHECK option. When
+it is set, the effect of passing an invalid UTF string as a pattern is
+undefined. It may cause your program to crash or loop.
+.P
+Note that this option can also be passed to \fBpcre2_match()\fP and
+\fBpcre2_dfa_match()\fP, to suppress UTF validity checking of the subject
+string.
+.P
+Note also that setting PCRE2_NO_UTF_CHECK at compile time does not disable the
+error that is given if an escape sequence for an invalid Unicode code point is
+encountered in the pattern. In particular, the so-called "surrogate" code
+points (0xd800 to 0xdfff) are invalid. If you want to allow escape sequences
+such as \ex{d800} you can set the PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES extra
+option, as described in the section entitled "Extra compile options"
+.\" HTML 
+.\" 
+below.
+.\"
+However, this is possible only in UTF-8 and UTF-32 modes, because these values
+are not representable in UTF-16.
+.sp
+  PCRE2_UCP
+.sp
+This option has two effects. Firstly, it change the way PCRE2 processes \eB,
+\eb, \eD, \ed, \eS, \es, \eW, \ew, and some of the POSIX character classes. By
+default, only ASCII characters are recognized, but if PCRE2_UCP is set, Unicode
+properties are used to classify characters. There are some PCRE2_EXTRA
+options (see below) that add finer control to this behaviour. More details are
+given in the section on
+.\" HTML 
+.\" 
+generic character types
+.\"
+in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+page.
+.P
+The second effect of PCRE2_UCP is to force the use of Unicode properties for
+upper/lower casing operations, even when PCRE2_UTF is not set. This makes it
+possible to process strings in the 16-bit UCS-2 code. This option is available
+only if PCRE2 has been compiled with Unicode support (which is the default).
+The PCRE2_EXTRA_CASELESS_RESTRICT option (see below) restricts caseless
+matching such that ASCII characters match only ASCII characters and non-ASCII
+characters match only non-ASCII characters.
+.sp
+  PCRE2_UNGREEDY
+.sp
+This option inverts the "greediness" of the quantifiers so that they are not
+greedy by default, but become greedy if followed by "?". It is not compatible
+with Perl. It can also be set by a (?U) option setting within the pattern.
+.sp
+  PCRE2_USE_OFFSET_LIMIT
+.sp
+This option must be set for \fBpcre2_compile()\fP if
+\fBpcre2_set_offset_limit()\fP is going to be used to set a non-default offset
+limit in a match context for matches that use this pattern. An error is
+generated if an offset limit is set without this option. For more details, see
+the description of \fBpcre2_set_offset_limit()\fP in the
+.\" HTML 
+.\" 
+section
+.\"
+that describes match contexts. See also the PCRE2_FIRSTLINE
+option above.
+.sp
+  PCRE2_UTF
+.sp
+This option causes PCRE2 to regard both the pattern and the subject strings
+that are subsequently processed as strings of UTF characters instead of
+single-code-unit strings. It is available when PCRE2 is built to include
+Unicode support (which is the default). If Unicode support is not available,
+the use of this option provokes an error. Details of how PCRE2_UTF changes the
+behaviour of PCRE2 are given in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+page. In particular, note that it changes the way PCRE2_CASELESS works.
+.
+.
+.\" HTML 
+.SS "Extra compile options"
+.rs
+.sp
+The option bits that can be set in a compile context by calling the
+\fBpcre2_set_compile_extra_options()\fP function are as follows:
+.sp
+  PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK
+.sp
+Since release 10.38 PCRE2 has forbidden the use of \eK within lookaround
+assertions, following Perl's lead. This option is provided to re-enable the
+previous behaviour (act in positive lookarounds, ignore in negative ones) in
+case anybody is relying on it.
+.sp
+  PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES
+.sp
+This option applies when compiling a pattern in UTF-8 or UTF-32 mode. It is
+forbidden in UTF-16 mode, and ignored in non-UTF modes. Unicode "surrogate"
+code points in the range 0xd800 to 0xdfff are used in pairs in UTF-16 to encode
+code points with values in the range 0x10000 to 0x10ffff. The surrogates cannot
+therefore be represented in UTF-16. They can be represented in UTF-8 and
+UTF-32, but are defined as invalid code points, and cause errors if encountered
+in a UTF-8 or UTF-32 string that is being checked for validity by PCRE2.
+.P
+These values also cause errors if encountered in escape sequences such as
+\ex{d912} within a pattern. However, it seems that some applications, when
+using PCRE2 to check for unwanted characters in UTF-8 strings, explicitly test
+for the surrogates using escape sequences. The PCRE2_NO_UTF_CHECK option does
+not disable the error that occurs, because it applies only to the testing of
+input strings for UTF validity.
+.P
+If the extra option PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES is set, surrogate code
+point values in UTF-8 and UTF-32 patterns no longer provoke errors and are
+incorporated in the compiled pattern. However, they can only match subject
+characters if the matching function is called with PCRE2_NO_UTF_CHECK set.
+.sp
+  PCRE2_EXTRA_ALT_BSUX
+.sp
+The original option PCRE2_ALT_BSUX causes PCRE2 to process \eU, \eu, and \ex in
+the way that ECMAscript (aka JavaScript) does. Additional functionality was
+defined by ECMAscript 6; setting PCRE2_EXTRA_ALT_BSUX has the effect of
+PCRE2_ALT_BSUX, but in addition it recognizes \eu{hhh..} as a hexadecimal
+character code, where hhh.. is any number of hexadecimal digits.
+.sp
+  PCRE2_EXTRA_ASCII_BSD
+.sp
+This option forces \ed to match only ASCII digits, even when PCRE2_UCP is set.
+It can be changed within a pattern by means of the (?aD) option setting.
+.sp
+  PCRE2_EXTRA_ASCII_BSS
+.sp
+This option forces \es to match only ASCII space characters, even when
+PCRE2_UCP is set. It can be changed within a pattern by means of the (?aS)
+option setting.
+.sp
+  PCRE2_EXTRA_ASCII_BSW
+.sp
+This option forces \ew to match only ASCII word characters, even when PCRE2_UCP
+is set. It can be changed within a pattern by means of the (?aW) option
+setting.
+.sp
+  PCRE2_EXTRA_ASCII_DIGIT
+.sp
+This option forces the POSIX character classes [:digit:] and [:xdigit:] to
+match only ASCII digits, even when PCRE2_UCP is set. It can be changed within
+a pattern by means of the (?aT) option setting.
+.sp
+  PCRE2_EXTRA_ASCII_POSIX
+.sp
+This option forces all the POSIX character classes, including [:digit:] and
+[:xdigit:], to match only ASCII characters, even when PCRE2_UCP is set. It can
+be changed within a pattern by means of the (?aP) option setting, but note that
+this also sets PCRE2_EXTRA_ASCII_DIGIT in order to ensure that (?-aP) unsets
+all ASCII restrictions for POSIX classes.
+.sp
+  PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL
+.sp
+This is a dangerous option. Use with care. By default, an unrecognized escape
+such as \ej or a malformed one such as \ex{2z} causes a compile-time error when
+detected by \fBpcre2_compile()\fP. Perl is somewhat inconsistent in handling
+such items: for example, \ej is treated as a literal "j", and non-hexadecimal
+digits in \ex{} are just ignored, though warnings are given in both cases if
+Perl's warning switch is enabled. However, a malformed octal number after \eo{
+always causes an error in Perl.
+.P
+If the PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL extra option is passed to
+\fBpcre2_compile()\fP, all unrecognized or malformed escape sequences are
+treated as single-character escapes. For example, \ej is a literal "j" and
+\ex{2z} is treated as the literal string "x{2z}". Setting this option means
+that typos in patterns may go undetected and have unexpected results. Also note
+that a sequence such as [\eN{] is interpreted as a malformed attempt at
+[\eN{...}] and so is treated as [N{] whereas [\eN] gives an error because an
+unqualified \eN is a valid escape sequence but is not supported in a character
+class. To reiterate: this is a dangerous option. Use with great care.
+.sp
+  PCRE2_EXTRA_CASELESS_RESTRICT
+.sp
+When either PCRE2_UCP or PCRE2_UTF is set, caseless matching follows Unicode
+rules, which allow for more than two cases per character. There are two
+case-equivalent character sets that contain both ASCII and non-ASCII
+characters. The ASCII letter S is case-equivalent to U+017f (long S) and the
+ASCII letter K is case-equivalent to U+212a (Kelvin sign). This option disables
+recognition of case-equivalences that cross the ASCII/non-ASCII boundary. In a
+caseless match, both characters must either be ASCII or non-ASCII. The option
+can be changed with a pattern by the (?r) option setting.
+.sp
+  PCRE2_EXTRA_ESCAPED_CR_IS_LF
+.sp
+There are some legacy applications where the escape sequence \er in a pattern
+is expected to match a newline. If this option is set, \er in a pattern is
+converted to \en so that it matches a LF (linefeed) instead of a CR (carriage
+return) character. The option does not affect a literal CR in the pattern, nor
+does it affect CR specified as an explicit code point such as \ex{0D}.
+.sp
+  PCRE2_EXTRA_MATCH_LINE
+.sp
+This option is provided for use by the \fB-x\fP option of \fBpcre2grep\fP. It
+causes the pattern only to match complete lines. This is achieved by
+automatically inserting the code for "^(?:" at the start of the compiled
+pattern and ")$" at the end. Thus, when PCRE2_MULTILINE is set, the matched
+line may be in the middle of the subject string. This option can be used with
+PCRE2_LITERAL.
+.sp
+  PCRE2_EXTRA_MATCH_WORD
+.sp
+This option is provided for use by the \fB-w\fP option of \fBpcre2grep\fP. It
+causes the pattern only to match strings that have a word boundary at the start
+and the end. This is achieved by automatically inserting the code for "\eb(?:"
+at the start of the compiled pattern and ")\eb" at the end. The option may be
+used with PCRE2_LITERAL. However, it is ignored if PCRE2_EXTRA_MATCH_LINE is
+also set.

+.P
+PCRE2 handles caseless matching, and determines whether characters are letters,

+point. However, this applies only to characters whose code points are less than
+256. By default, higher-valued code points never match escapes such as \ew or
+\ed.
+.P
+When PCRE2 is built with Unicode support (the default), certain Unicode
+character properties can be tested with \ep and \eP, or, alternatively, the
+PCRE2_UCP option can be set when a pattern is compiled; this causes \ew and
+friends to use Unicode property support instead of the built-in tables.
+PCRE2_UCP also causes upper/lower casing operations on characters with code
+points greater than 127 to use Unicode properties. These effects apply even
+when PCRE2_UTF is not set. There are, however, some PCRE2_EXTRA options (see
+above) that can be used to modify or suppress them.
+.P
+The use of locales with Unicode is discouraged. If you are handling characters
+with code points greater than 127, you should either use Unicode support, or
+use locales, but not try to mix the two.
+.P
+PCRE2 contains a built-in set of character tables that are used by default.
+These are sufficient for many applications. Normally, the internal tables
+recognize only ASCII characters. However, when PCRE2 is built, it is possible
+to cause the internal tables to be rebuilt in the default "C" locale of the
+local system, which may cause them to be different.
+.P
+The built-in tables can be overridden by tables supplied by the application
+that calls PCRE2. These may be created in a different locale from the default.
+As more and more applications change to using Unicode, the need for this locale
+support is expected to die away.
+.P
+External tables are built by calling the \fBpcre2_maketables()\fP function, in
+the relevant locale. The only argument to this function is a general context,
+which can be used to pass a custom memory allocator. If the argument is NULL,
+the system \fBmalloc()\fP is used. The result can be passed to
+\fBpcre2_compile()\fP as often as necessary, by creating a compile context and
+calling \fBpcre2_set_character_tables()\fP to set the tables pointer therein.
+.P
+For example, to build and use tables that are appropriate for the French locale
+(where accented characters with values greater than 127 are treated as
+letters), the following code could be used:
+.sp
+  setlocale(LC_CTYPE, "fr_FR");
+  tables = pcre2_maketables(NULL);
+  ccontext = pcre2_compile_context_create(NULL);
+  pcre2_set_character_tables(ccontext, tables);
+  re = pcre2_compile(..., ccontext);
+.sp
+The locale name "fr_FR" is used on Linux and other Unix-like systems; if you
+are using Windows, the name for the French locale is "french".
+.P
+The pointer that is passed (via the compile context) to \fBpcre2_compile()\fP
+is saved with the compiled pattern, and the same tables are used by the
+matching functions. Thus, for any single pattern, compilation and matching both
+happen in the same locale, but different patterns can be processed in different
+locales.
+.P
+It is the caller's responsibility to ensure that the memory containing the
+tables remains available while they are still in use. When they are no longer
+needed, you can discard them using \fBpcre2_maketables_free()\fP, which should
+pass as its first parameter the same global context that was used to create the
+tables.
+.
+.
+.SS "Saving locale tables"
+.rs
+.sp
+The tables described above are just a sequence of binary bytes, which makes
+them independent of hardware characteristics such as endianness or whether the

+can therefore be saved in a file or elsewhere and re-used later, even in a

+.\"
+The first argument for \fBpcre2_pattern_info()\fP is a pointer to the compiled
+pattern. The second argument specifies which piece of information is required,
+and the third argument is a pointer to a variable to receive the data. If the
+third argument is NULL, the first argument is ignored, and the function returns
+the size in bytes of the variable that is required for the information

+The "magic number" is placed at the start of each compiled pattern as a simple

+pcre2_set_compile_extra_options() function.
+.P
+For example, if the pattern /(*UTF)abc/ is compiled with the PCRE2_EXTENDED

+pattern. (This was different in some earlier releases.)
+.P
+A pattern compiled without PCRE2_ANCHORED is automatically anchored by PCRE2 if
+the first significant item in every top-level branch is one of the following:
+.sp
+  ^     unless PCRE2_MULTILINE is set
+  \eA    always
+  \eG    always
+  .*    sometimes - see below
+.sp
+When .* is the first significant item, anchoring is possible only when all the
+following are true:
+.sp
+  .* is not in an atomic group
+.\" JOIN
+  .* is not in a capture group that is the subject
+       of a backreference
+  PCRE2_DOTALL is in force for .*
+  Neither (*PRUNE) nor (*SKIP) appears in the pattern
+  PCRE2_NO_DOTSTAR_ANCHOR is not set
+.sp
+For patterns that are auto-anchored, the PCRE2_ANCHORED bit is set in the
+options returned for PCRE2_INFO_ALLOPTIONS.
+.sp
+  PCRE2_INFO_BACKREFMAX
+.sp
+Return the number of the highest backreference in the pattern. The third
+argument should point to a \fBuint32_t\fP variable. Named capture groups
+acquire numbers as well as names, and these count towards the highest
+backreference. Backreferences such as \e4 or \eg{12} match the captured
+characters of the given group, but in addition, the check that a capture
+group is set in a conditional group such as (?(3)a|b) is also a backreference.
+Zero is returned if there are no backreferences.
+.sp
+  PCRE2_INFO_BSR
+.sp
+The output is a uint32_t integer whose value indicates what character sequences
+the \eR escape sequence matches. A value of PCRE2_BSR_UNICODE means that \eR
+matches any Unicode line ending sequence; a value of PCRE2_BSR_ANYCRLF means
+that \eR matches only CR, LF, or CRLF.
+.sp
+  PCRE2_INFO_CAPTURECOUNT
+.sp
+Return the highest capture group number in the pattern. In patterns where (?|
+is not used, this is also the total number of capture groups. The third
+argument should point to a \fBuint32_t\fP variable.
+.sp
+  PCRE2_INFO_DEPTHLIMIT
+.sp
+If the pattern set a backtracking depth limit by including an item of the form
+(*LIMIT_DEPTH=nnnn) at the start, the value is returned. The third argument
+should point to a uint32_t integer. If no such value has been set, the call to
+\fBpcre2_pattern_info()\fP returns the error PCRE2_ERROR_UNSET. Note that this
+limit will only be used during matching if it is less than the limit set or
+defaulted by the caller of the match function.
+.sp
+  PCRE2_INFO_FIRSTBITMAP
+.sp
+In the absence of a single first code unit for a non-anchored pattern,
+\fBpcre2_compile()\fP may construct a 256-bit table that defines a fixed set of
+values for the first code unit in any match. For example, a pattern that starts
+with [abc] results in a table with three bits set. When code unit values
+greater than 255 are supported, the flag bit for 255 means "any code unit of
+value 255 or above". If such a table was constructed, a pointer to it is
+returned. Otherwise NULL is returned. The third argument should point to a
+\fBconst uint8_t *\fP variable.
+.sp
+  PCRE2_INFO_FIRSTCODETYPE
+.sp
+Return information about the first code unit of any matched string, for a
+non-anchored pattern. The third argument should point to a \fBuint32_t\fP
+variable. If there is a fixed first value, for example, the letter "c" from a
+pattern such as (cat|cow|coyote), 1 is returned, and the value can be retrieved
+using PCRE2_INFO_FIRSTCODEUNIT. If there is no fixed first value, but it is
+known that a match can occur only at the start of the subject or following a
+newline in the subject, 2 is returned. Otherwise, and for anchored patterns, 0
+is returned.
+.sp
+  PCRE2_INFO_FIRSTCODEUNIT
+.sp
+Return the value of the first code unit of any matched string for a pattern
+where PCRE2_INFO_FIRSTCODETYPE returns 1; otherwise return 0. The third
+argument should point to a \fBuint32_t\fP variable. In the 8-bit library, the
+value is always less than 256. In the 16-bit library the value can be up to
+0xffff. In the 32-bit library in UTF-32 mode the value can be up to 0x10ffff,
+and up to 0xffffffff when not using UTF-32 mode.
+.sp
+  PCRE2_INFO_FRAMESIZE
+.sp
+Return the size (in bytes) of the data frames that are used to remember
+backtracking positions when the pattern is processed by \fBpcre2_match()\fP
+without the use of JIT. The third argument should point to a \fBsize_t\fP
+variable. The frame size depends on the number of capturing parentheses in the
+pattern. Each additional capture group adds two PCRE2_SIZE variables.
+.sp
+  PCRE2_INFO_HASBACKSLASHC
+.sp
+Return 1 if the pattern contains any instances of \eC, otherwise 0. The third
+argument should point to a \fBuint32_t\fP variable.
+.sp
+  PCRE2_INFO_HASCRORLF
+.sp
+Return 1 if the pattern contains any explicit matches for CR or LF characters,
+otherwise 0. The third argument should point to a \fBuint32_t\fP variable. An
+explicit match is either a literal CR or LF character, or \er or \en or one of
+the equivalent hexadecimal or octal escape sequences.
+.sp
+  PCRE2_INFO_HEAPLIMIT
+.sp
+If the pattern set a heap memory limit by including an item of the form
+(*LIMIT_HEAP=nnnn) at the start, the value is returned. The third argument
+should point to a uint32_t integer. If no such value has been set, the call to
+\fBpcre2_pattern_info()\fP returns the error PCRE2_ERROR_UNSET. Note that this
+limit will only be used during matching if it is less than the limit set or
+defaulted by the caller of the match function.
+.sp
+  PCRE2_INFO_JCHANGED
+.sp
+Return 1 if the (?J) or (?-J) option setting is used in the pattern, otherwise
+0. The third argument should point to a \fBuint32_t\fP variable. (?J) and
+(?-J) set and unset the local PCRE2_DUPNAMES option, respectively.
+.sp
+  PCRE2_INFO_JITSIZE
+.sp
+If the compiled pattern was successfully processed by
+\fBpcre2_jit_compile()\fP, return the size of the JIT compiled code, otherwise
+return zero. The third argument should point to a \fBsize_t\fP variable.
+.sp
+  PCRE2_INFO_LASTCODETYPE
+.sp
+Returns 1 if there is a rightmost literal code unit that must exist in any
+matched string, other than at its start. The third argument should point to a
+\fBuint32_t\fP variable. If there is no such value, 0 is returned. When 1 is
+returned, the code unit value itself can be retrieved using
+PCRE2_INFO_LASTCODEUNIT. For anchored patterns, a last literal value is
+recorded only if it follows something of variable length. For example, for the
+pattern /^a\ed+z\ed+/ the returned value is 1 (with "z" returned from
+PCRE2_INFO_LASTCODEUNIT), but for /^a\edz\ed/ the returned value is 0.
+.sp
+  PCRE2_INFO_LASTCODEUNIT
+.sp
+Return the value of the rightmost literal code unit that must exist in any
+matched string, other than at its start, for a pattern where
+PCRE2_INFO_LASTCODETYPE returns 1. Otherwise, return 0. The third argument
+should point to a \fBuint32_t\fP variable.
+.sp
+  PCRE2_INFO_MATCHEMPTY
+.sp
+Return 1 if the pattern might match an empty string, otherwise 0. The third
+argument should point to a \fBuint32_t\fP variable. When a pattern contains
+recursive subroutine calls it is not always possible to determine whether or
+not it can match an empty string. PCRE2 takes a cautious approach and returns 1
+in such cases.
+.sp
+  PCRE2_INFO_MATCHLIMIT
+.sp
+If the pattern set a match limit by including an item of the form
+(*LIMIT_MATCH=nnnn) at the start, the value is returned. The third argument
+should point to a uint32_t integer. If no such value has been set, the call to
+\fBpcre2_pattern_info()\fP returns the error PCRE2_ERROR_UNSET. Note that this
+limit will only be used during matching if it is less than the limit set or
+defaulted by the caller of the match function.
+.sp
+  PCRE2_INFO_MAXLOOKBEHIND
+.sp
+A lookbehind assertion moves back a certain number of characters (not code
+units) when it starts to process each of its branches. This request returns the
+largest of these backward moves. The third argument should point to a uint32_t
+integer. The simple assertions \eb and \eB require a one-character lookbehind
+and cause PCRE2_INFO_MAXLOOKBEHIND to return 1 in the absence of anything
+longer. \eA also registers a one-character lookbehind, though it does not
+actually inspect the previous character.
+.P
+Note that this information is useful for multi-segment matching only
+if the pattern contains no nested lookbehinds. For example, the pattern
+(?<=a(?<=ba)c) returns a maximum lookbehind of 2, but when it is processed, the
+first lookbehind moves back by two characters, matches one character, then the
+nested lookbehind also moves back by two characters. This puts the matching
+point three characters earlier than it was at the start.
+PCRE2_INFO_MAXLOOKBEHIND is really only useful as a debugging tool. See the
+.\" HREF
+\fBpcre2partial\fP
+.\"
+documentation for a discussion of multi-segment matching.
+.sp
+  PCRE2_INFO_MINLENGTH
+.sp
+If a minimum length for matching subject strings was computed, its value is
+returned. Otherwise the returned value is 0. This value is not computed when
+PCRE2_NO_START_OPTIMIZE is set. The value is a number of characters, which in
+UTF mode may be different from the number of code units. The third argument
+should point to a \fBuint32_t\fP variable. The value is a lower bound to the
+length of any matching string. There may not be any strings of that length that
+do actually match, but every string that does match is at least that long.
+.sp
+  PCRE2_INFO_NAMECOUNT
+  PCRE2_INFO_NAMEENTRYSIZE
+  PCRE2_INFO_NAMETABLE
+.sp
+PCRE2 supports the use of named as well as numbered capturing parentheses. The
+names are just an additional way of identifying the parentheses, which still
+acquire numbers. Several convenience functions such as
+\fBpcre2_substring_get_byname()\fP are provided for extracting captured
+substrings by name. It is also possible to extract the data directly, by first
+converting the name to a number in order to access the correct pointers in the
+output vector (described with \fBpcre2_match()\fP below). To do the conversion,
+you need to use the name-to-number map, which is described by these three
+values.
+.P
+The map consists of a number of fixed-size entries. PCRE2_INFO_NAMECOUNT gives
+the number of entries, and PCRE2_INFO_NAMEENTRYSIZE gives the size of each
+entry in code units; both of these return a \fBuint32_t\fP value. The entry
+size depends on the length of the longest name.
+.P
+PCRE2_INFO_NAMETABLE returns a pointer to the first entry of the table. This is
+a PCRE2_SPTR pointer to a block of code units. In the 8-bit library, the first
+two bytes of each entry are the number of the capturing parenthesis, most
+significant byte first. In the 16-bit library, the pointer points to 16-bit
+code units, the first of which contains the parenthesis number. In the 32-bit
+library, the pointer points to 32-bit code units, the first of which contains
+the parenthesis number. The rest of the entry is the corresponding name, zero
+terminated.
+.P
+The names are in alphabetical order. If (?| is used to create multiple capture
+groups with the same number, as described in the
+.\" HTML 
+.\" 
+section on duplicate group numbers
+.\"
+in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+page, the groups may be given the same name, but there is only one entry in the
+table. Different names for groups of the same number are not permitted.
+.P
+Duplicate names for capture groups with different numbers are permitted, but
+only if PCRE2_DUPNAMES is set. They appear in the table in the order in which
+they were found in the pattern. In the absence of (?| this is the order of
+increasing number; when (?| is used this is not necessarily the case because
+later capture groups may have lower numbers.
+.P
+As a simple example of the name/number table, consider the following pattern
+after compilation by the 8-bit library (assume PCRE2_EXTENDED is set, so white
+space - including newlines - is ignored):
+.sp
+.\" JOIN
+  (? (?(\ed\ed)?\ed\ed) -
+  (?\ed\ed) - (?\ed\ed) )
+.sp
+There are four named capture groups, so the table has four entries, and each
+entry in the table is eight bytes long. The table is as follows, with
+non-printing bytes shows in hexadecimal, and undefined bytes shown as ??:
+.sp
+  00 01 d  a  t  e  00 ??
+  00 05 d  a  y  00 ?? ??
+  00 04 m  o  n  t  h  00
+  00 02 y  e  a  r  00 ??
+.sp
+When writing code to extract data from named capture groups using the
+name-to-number map, remember that the length of the entries is likely to be
+different for each compiled pattern.
+.sp
+  PCRE2_INFO_NEWLINE
+.sp
+The output is one of the following \fBuint32_t\fP values:
+.sp
+  PCRE2_NEWLINE_CR       Carriage return (CR)
+  PCRE2_NEWLINE_LF       Linefeed (LF)
+  PCRE2_NEWLINE_CRLF     Carriage return, linefeed (CRLF)
+  PCRE2_NEWLINE_ANY      Any Unicode line ending
+  PCRE2_NEWLINE_ANYCRLF  Any of CR, LF, or CRLF
+  PCRE2_NEWLINE_NUL      The NUL character (binary zero)
+.sp
+This identifies the character sequence that will be recognized as meaning
+"newline" while matching.
+.sp
+  PCRE2_INFO_SIZE
+.sp
+Return the size of the compiled pattern in bytes (for all three libraries). The
+third argument should point to a \fBsize_t\fP variable. This value includes the
+size of the general data block that precedes the code units of the compiled
+pattern itself. The value that is used when \fBpcre2_compile()\fP is getting
+memory in which to place the compiled pattern may be slightly larger than the
+value returned by this option, because there are cases where the code that
+calculates the size has to over-estimate. Processing a pattern with the JIT
+compiler does not alter the value returned by this option.

+Information about a successful or unsuccessful match is placed in a match
+data block, which is an opaque structure that is accessed by function calls. In
+particular, the match data block contains a vector of offsets into the subject
+string that define the matched parts of the subject. This is known as the
+\fIovector\fP.
+.P
+Before calling \fBpcre2_match()\fP, \fBpcre2_dfa_match()\fP, or
+\fBpcre2_jit_match()\fP you must create a match data block by calling one of
+the creation functions above. For \fBpcre2_match_data_create()\fP, the first
+argument is the number of pairs of offsets in the \fIovector\fP.
+.P
+When using \fBpcre2_match()\fP, one pair of offsets is required to identify the
+string that matched the whole pattern, with an additional pair for each
+captured substring. For example, a value of 4 creates enough space to record
+the matched portion of the subject plus three captured substrings.
+.P
+When using \fBpcre2_dfa_match()\fP there may be multiple matched substrings of
+different lengths at the same point in the subject. The ovector should be made
+large enough to hold as many as are expected.
+.P
+A minimum of at least 1 pair is imposed by \fBpcre2_match_data_create()\fP, so
+it is always possible to return the overall matched string in the case of
+\fBpcre2_match()\fP or the longest match in the case of
+\fBpcre2_dfa_match()\fP. The maximum number of pairs is 65535; if the first
+argument of \fBpcre2_match_data_create()\fP is greater than this, 65535 is
+used.
+.P
+The second argument of \fBpcre2_match_data_create()\fP is a pointer to a
+general context, which can specify custom memory management for obtaining the
+memory for the match data block. If you are not using custom memory management,
+pass NULL, which causes \fBmalloc()\fP to be used.
+.P
+For \fBpcre2_match_data_create_from_pattern()\fP, the first argument is a
+pointer to a compiled pattern. The ovector is created to be exactly the right
+size to hold all the substrings a pattern might capture when matched using
+\fBpcre2_match()\fP. You should not use this call when matching with
+\fBpcre2_dfa_match()\fP. The second argument is again a pointer to a general
+context, but in this case if NULL is passed, the memory is obtained using the
+same allocator that was used for the compiled pattern (custom or default).
+.P
+A match data block can be used many times, with the same or different compiled

+block only when the error is PCRE2_ERROR_NOMATCH, PCRE2_ERROR_PARTIAL, or one

+on the error, and is detailed below.
+.P
+When one of the matching functions is called, pointers to the compiled pattern
+and the subject string are set in the match data block so that they can be
+referenced by the extraction functions after a successful match. After running

+.
+.SS "The string to be matched by \fBpcre2_match()\fP"
+.rs
+.sp
+The subject string is passed to \fBpcre2_match()\fP as a pointer in
+\fIsubject\fP, a length in \fIlength\fP, and a starting offset in
+\fIstartoffset\fP. The length and offset are in code units, not characters.
+That is, they are in bytes for the 8-bit library, 16-bit code units for the
+16-bit library, and 32-bit code units for the 32-bit library, whether or not
+UTF processing is enabled. As a special case, if \fIsubject\fP is NULL and
+\fIlength\fP is zero, the subject is assumed to be an empty string. If
+\fIlength\fP is non-zero, an error occurs if \fIsubject\fP is NULL.
+.P
+If \fIstartoffset\fP is greater than the length of the subject,
+\fBpcre2_match()\fP returns PCRE2_ERROR_BADOFFSET. When the starting offset is
+zero, the search for a match starts at the beginning of the subject, and this
+is by far the most common case. In UTF-8 or UTF-16 mode, the starting offset
+must point to the start of a character, or to the end of the subject (in UTF-32
+mode, one code unit equals one character, so all offsets are valid). Like the
+pattern string, the subject may contain binary zeros.
+.P
+A non-zero starting offset is useful when searching for another match in the
+same subject by calling \fBpcre2_match()\fP again after a previous success.
+Setting \fIstartoffset\fP differs from passing over a shortened string and
+setting PCRE2_NOTBOL in the case of a pattern that begins with any kind of
+lookbehind. For example, consider the pattern
+.sp
+  \eBiss\eB
+.sp
+which finds occurrences of "iss" in the middle of words. (\eB matches only if
+the current position in the subject is not a word boundary.) When applied to
+the string "Mississippi" the first call to \fBpcre2_match()\fP finds the first
+occurrence. If \fBpcre2_match()\fP is called again with just the remainder of
+the subject, namely "issippi", it does not match, because \eB is always false
+at the start of the subject, which is deemed to be a word boundary. However, if
+\fBpcre2_match()\fP is passed the entire string again, but with
+\fIstartoffset\fP set to 4, it finds the second occurrence of "iss" because it
+is able to look behind the starting point to discover that it is preceded by a
+letter.
+.P
+Finding all the matches in a subject is tricky when the pattern can match an
+empty string. It is possible to emulate Perl's /g behaviour by first trying the
+match again at the same offset, with the PCRE2_NOTEMPTY_ATSTART and
+PCRE2_ANCHORED options, and then if that fails, advancing the starting offset
+and trying an ordinary match again. There is some code that demonstrates how to
+do this in the
+.\" HREF
+\fBpcre2demo\fP
+.\"
+sample program. In the most general case, you have to check to see if the
+newline convention recognizes CRLF as a newline, and if so, and the current
+character is CR followed by LF, advance the starting offset by two characters
+instead of one.
+.P
+If a non-zero starting offset is passed when the pattern is anchored, a single
+attempt to match at the given offset is made. This can only succeed if the
+pattern does not require the match to be at the start of the subject. In other
+words, the anchoring must be the result of setting the PCRE2_ANCHORED option or
+the use of .* with PCRE2_DOTALL, not by starting the pattern with ^ or \eA.

+.\" HTML 
+.SS "Option bits for \fBpcre2_match()\fP"
+.rs
+.sp
+The unused bits of the \fIoptions\fP argument for \fBpcre2_match()\fP must be
+zero. The only bits that may be set are PCRE2_ANCHORED,
+PCRE2_COPY_MATCHED_SUBJECT, PCRE2_DISABLE_RECURSELOOP_CHECK, PCRE2_ENDANCHORED,
+PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART,
+PCRE2_NO_JIT, PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT.
+Their action is described below.
+.P
+Setting PCRE2_ANCHORED or PCRE2_ENDANCHORED at match time is not supported by
+the just-in-time (JIT) compiler. If it is set, JIT matching is disabled and the
+interpretive code in \fBpcre2_match()\fP is run.
+PCRE2_DISABLE_RECURSELOOP_CHECK is ignored by JIT, but apart from PCRE2_NO_JIT
+(obviously), the remaining options are supported for JIT matching.
+.sp
+  PCRE2_ANCHORED
+.sp
+The PCRE2_ANCHORED option limits \fBpcre2_match()\fP to matching at the first
+matching position. If a pattern was compiled with PCRE2_ANCHORED, or turned out
+to be anchored by virtue of its contents, it cannot be made unachored at
+matching time. Note that setting the option at match time disables JIT
+matching.
+.sp
+  PCRE2_COPY_MATCHED_SUBJECT
+.sp
+By default, a pointer to the subject is remembered in the match data block so
+that, after a successful match, it can be referenced by the substring
+extraction functions. This means that the subject's memory must not be freed
+until all such operations are complete. For some applications where the
+lifetime of the subject string is not guaranteed, it may be necessary to make a
+copy of the subject string, but it is wasteful to do this unless the match is
+successful. After a successful match, if PCRE2_COPY_MATCHED_SUBJECT is set, the
+subject is copied and the new pointer is remembered in the match data block
+instead of the original subject pointer. The memory allocator that was used for
+the match block itself is used. The copy is automatically freed when
+\fBpcre2_match_data_free()\fP is called to free the match data block. It is also
+automatically freed if the match data block is re-used for another match
+operation.
+.sp
+  PCRE2_DISABLE_RECURSELOOP_CHECK
+.sp
+This option is relevant only to \fBpcre2_match()\fP for interpretive matching.
+It is ignored when JIT is used, and is forbidden for \fBpcre2_dfa_match()\fP.
+.P
+The use of recursion in patterns can lead to infinite loops. In the
+interpretive matcher these would be eventually caught by the match or heap
+limits, but this could take a long time and/or use a lot of memory if the
+limits are large. There is therefore a check at the start of each recursion.
+If the same group is still active from a previous call, and the current subject
+pointer is the same as it was at the start of that group, and the furthest
+inspected character of the subject has not changed, an error is generated.
+.P
+There are rare cases of matches that would complete, but nevertheless trigger
+this error. This option disables the check. It is provided mainly for testing
+when comparing JIT and interpretive behaviour.
+.sp
+  PCRE2_ENDANCHORED
+.sp
+If the PCRE2_ENDANCHORED option is set, any string that \fBpcre2_match()\fP
+matches must be right at the end of the subject string. Note that setting the
+option at match time disables JIT matching.
+.sp
+  PCRE2_NOTBOL
+.sp
+This option specifies that first character of the subject string is not the
+beginning of a line, so the circumflex metacharacter should not match before
+it. Setting this without having set PCRE2_MULTILINE at compile time causes
+circumflex never to match. This option affects only the behaviour of the
+circumflex metacharacter. It does not affect \eA.
+.sp
+  PCRE2_NOTEOL
+.sp
+This option specifies that the end of the subject string is not the end of a
+line, so the dollar metacharacter should not match it nor (except in multiline
+mode) a newline immediately before it. Setting this without having set
+PCRE2_MULTILINE at compile time causes dollar never to match. This option
+affects only the behaviour of the dollar metacharacter. It does not affect \eZ
+or \ez.
+.sp
+  PCRE2_NOTEMPTY
+.sp
+An empty string is not considered to be a valid match if this option is set. If
+there are alternatives in the pattern, they are tried. If all the alternatives
+match the empty string, the entire match fails. For example, if the pattern
+.sp
+  a?b?
+.sp
+is applied to a string not beginning with "a" or "b", it matches an empty
+string at the start of the subject. With PCRE2_NOTEMPTY set, this match is not
+valid, so \fBpcre2_match()\fP searches further into the string for occurrences
+of "a" or "b".
+.sp
+  PCRE2_NOTEMPTY_ATSTART
+.sp
+This is like PCRE2_NOTEMPTY, except that it locks out an empty string match
+only at the first matching position, that is, at the start of the subject plus
+the starting offset. An empty string match later in the subject is permitted.
+If the pattern is anchored, such a match can occur only if the pattern contains
+\eK.
+.sp
+  PCRE2_NO_JIT
+.sp
+By default, if a pattern has been successfully processed by
+\fBpcre2_jit_compile()\fP, JIT is automatically used when \fBpcre2_match()\fP
+is called with options that JIT supports. Setting PCRE2_NO_JIT disables the use
+of JIT; it forces matching to be done by the interpreter.
+.sp
+  PCRE2_NO_UTF_CHECK
+.sp
+When PCRE2_UTF is set at compile time, the validity of the subject as a UTF
+string is checked unless PCRE2_NO_UTF_CHECK is passed to \fBpcre2_match()\fP or
+PCRE2_MATCH_INVALID_UTF was passed to \fBpcre2_compile()\fP. The latter special
+case is discussed in detail in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+documentation.
+.P
+In the default case, if a non-zero starting offset is given, the check is
+applied only to that part of the subject that could be inspected during
+matching, and there is a check that the starting offset points to the first
+code unit of a character or to the end of the subject. If there are no
+lookbehind assertions in the pattern, the check starts at the starting offset.
+Otherwise, it starts at the length of the longest lookbehind before the
+starting offset, or at the start of the subject if there are not that many
+characters before the starting offset. Note that the sequences \eb and \eB are
+one-character lookbehinds.
+.P
+The check is carried out before any other processing takes place, and a
+negative error code is returned if the check fails. There are several UTF error
+codes for each code unit width, corresponding to different problems with the
+code unit sequence. There are discussions about the validity of
+.\" HTML 
+.\" 
+UTF-8 strings,
+.\"
+.\" HTML 
+.\" 
+UTF-16 strings,
+.\"
+and
+.\" HTML 
+.\" 
+UTF-32 strings
+.\"
+in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+documentation.
+.P
+If you know that your subject is valid, and you want to skip this check for
+performance reasons, you can set the PCRE2_NO_UTF_CHECK option when calling
+\fBpcre2_match()\fP. You might want to do this for the second and subsequent
+calls to \fBpcre2_match()\fP if you are making repeated calls to find multiple
+matches in the same subject string.
+.P
+\fBWarning:\fP Unless PCRE2_MATCH_INVALID_UTF was set at compile time, when
+PCRE2_NO_UTF_CHECK is set at match time the effect of passing an invalid
+string as a subject, or an invalid value of \fIstartoffset\fP, is undefined.
+Your program may crash or loop indefinitely or give wrong results.
+.sp
+  PCRE2_PARTIAL_HARD
+  PCRE2_PARTIAL_SOFT
+.sp
+These options turn on the partial matching feature. A partial match occurs if
+the end of the subject string is reached successfully, but there are not enough
+subject characters to complete the match. In addition, either at least one
+character must have been inspected or the pattern must contain a lookbehind, or
+the pattern must be one that could match an empty string.
+.P
+If this situation arises when PCRE2_PARTIAL_SOFT (but not PCRE2_PARTIAL_HARD)
+is set, matching continues by testing any remaining alternatives. Only if no
+complete match can be found is PCRE2_ERROR_PARTIAL returned instead of
+PCRE2_ERROR_NOMATCH. In other words, PCRE2_PARTIAL_SOFT specifies that the
+caller is prepared to handle a partial match, but only if no complete match can
+be found.
+.P
+If PCRE2_PARTIAL_HARD is set, it overrides PCRE2_PARTIAL_SOFT. In this case, if
+a partial match is found, \fBpcre2_match()\fP immediately returns
+PCRE2_ERROR_PARTIAL, without considering any other alternatives. In other
+words, when PCRE2_PARTIAL_HARD is set, a partial match is considered to be more
+important that an alternative complete match.

+There is a more detailed discussion of partial and multi-segment matching, with
+examples, in the

+.
+.SH "NEWLINE HANDLING WHEN MATCHING"
+.rs
+.sp
+When PCRE2 is built, a default newline convention is set; this is usually the
+standard convention for the operating system. The default can be overridden in
+a
+.\" HTML 
+.\" 
+compile context
+.\"
+by calling \fBpcre2_set_newline()\fP. It can also be overridden by starting a
+pattern string with, for example, (*CRLF), as described in the
+.\" HTML 
+.\" 
+section on newline conventions
+.\"
+in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+page. During matching, the newline choice affects the behaviour of the dot,
+circumflex, and dollar metacharacters. It may also alter the way the match
+starting position is advanced after a match failure for an unanchored pattern.
+.P
+When PCRE2_NEWLINE_CRLF, PCRE2_NEWLINE_ANYCRLF, or PCRE2_NEWLINE_ANY is set as
+the newline convention, and a match attempt for an unanchored pattern fails
+when the current starting position is at a CRLF sequence, and the pattern
+contains no explicit matches for CR or LF characters, the match position is
+advanced by two characters instead of one, in other words, to after the CRLF.
+.P
+The above rule is a compromise that makes the most common cases work as
+expected. For example, if the pattern is .+A (and the PCRE2_DOTALL option is
+not set), it does not match the string "\er\enA" because, after failing at the
+start, it skips both the CR and the LF before retrying. However, the pattern
+[\er\en]A does match that string, because it contains an explicit CR or LF
+reference, and so advances only by one character after the first failure.
+.P
+An explicit match for CR of LF is either a literal appearance of one of those
+characters in the pattern, or one of the \er or \en or equivalent octal or
+hexadecimal escape sequences. Implicit matches such as [^X] do not count, nor
+does \es, even though it includes CR and LF in the characters that it matches.
+.P
+Notwithstanding the above, anomalous effects may still occur when CRLF is a
+valid newline sequence and explicit \er or \en escapes appear in the pattern.

+.fi
+.P
+In general, a pattern matches a certain portion of the subject, and in
+addition, further substrings from the subject may be picked out by
+parenthesized parts of the pattern. Following the usage in Jeffrey Friedl's
+book, this is called "capturing" in what follows, and the phrase "capture
+group" (Perl terminology) is used for a fragment of a pattern that picks out a
+substring. PCRE2 supports several other kinds of parenthesized group that do
+not cause substrings to be captured. The \fBpcre2_pattern_info()\fP function
+can be used to find out how many capture groups there are in a compiled
+pattern.
+.P
+You can use auxiliary functions for accessing captured substrings
+.\" HTML 
+.\" 
+by number
+.\"
+or
+.\" HTML 
+.\" 
+by name,
+.\"
+as described in sections below.
+.P
+Alternatively, you can make direct use of the vector of PCRE2_SIZE values,
+called the \fBovector\fP, which contains the offsets of captured strings. It is
+part of the
+.\" HTML 
+.\" 
+match data block.
+.\"
+The function \fBpcre2_get_ovector_pointer()\fP returns the address of the
+ovector, and \fBpcre2_get_ovector_count()\fP returns the number of pairs of
+values it contains.
+.P
+Within the ovector, the first in each pair of values is set to the offset of
+the first code unit of a substring, and the second is set to the offset of the
+first code unit after the end of a substring. These values are always code unit
+offsets, not character offsets. That is, they are byte offsets in the 8-bit
+library, 16-bit offsets in the 16-bit library, and 32-bit offsets in the 32-bit
+library.
+.P
+After a partial match (error return PCRE2_ERROR_PARTIAL), only the first pair
+of offsets (that is, \fIovector[0]\fP and \fIovector[1]\fP) are set. They
+identify the part of the subject that was partially matched. See the
+.\" HREF
+\fBpcre2partial\fP
+.\"
+documentation for details of partial matching.
+.P
+After a fully successful match, the first pair of offsets identifies the
+portion of the subject string that was matched by the entire pattern. The next
+pair is used for the first captured substring, and so on. The value returned by
+\fBpcre2_match()\fP is one more than the highest numbered pair that has been
+set. For example, if two substrings have been captured, the returned value is
+3. If there are no captured substrings, the return value from a successful
+match is 1, indicating that just the first pair of offsets has been set.
+.P
+If a pattern uses the \eK escape sequence within a positive assertion, the
+reported start of a successful match can be greater than the end of the match.
+For example, if the pattern (?=ab\eK) is matched against "ab", the start and
+end offset values for the match are 2 and 0.
+.P
+If a capture group is matched repeatedly within a single match operation, it is
+the last portion of the subject that it matched that is returned.
+.P
+If the ovector is too small to hold all the captured substring offsets, as much
+as possible is filled in, and the function returns a value of zero. If captured
+substrings are not of interest, \fBpcre2_match()\fP may be called with a match
+data block whose ovector is of minimum length (that is, one pair).
+.P
+It is possible for capture group number \fIn+1\fP to match some part of the
+subject when group \fIn\fP has not been used at all. For example, if the string
+"abc" is matched against the pattern (a|(z))(bc) the return from the function
+is 4, and groups 1 and 3 are matched, but 2 is not. When this happens, both
+values in the offset pairs corresponding to unused groups are set to
+PCRE2_UNSET.
+.P
+Offset values that correspond to unused groups at the end of the expression are
+also set to PCRE2_UNSET. For example, if the string "abc" is matched against
+the pattern (abc)(x(yz)?)? groups 2 and 3 are not matched. The return from the
+function is 2, because the highest used capture group number is 1. The offsets
+for the second and third capture groups (assuming the vector is large enough,
+of course) are set to PCRE2_UNSET.
+.P
+Elements in the ovector that do not correspond to capturing parentheses in the
+pattern are never changed. That is, if a pattern contains \fIn\fP capturing
+parentheses, no more than \fIovector[0]\fP to \fIovector[2n+1]\fP are set by
+\fBpcre2_match()\fP. The other elements retain whatever values they previously
+had. After a failed match attempt, the contents of the ovector are unchanged.

+undefined.
+.P
+After a successful match, a partial match (PCRE2_ERROR_PARTIAL), or a failure
+to match (PCRE2_ERROR_NOMATCH), a mark name may be available. The function
+\fBpcre2_get_mark()\fP can be called to access this name, which can be
+specified in the pattern by any of the backtracking control verbs, not just
+(*MARK). The same function applies to all the verbs. It returns a pointer to
+the zero-terminated name, which is within the compiled pattern. If no name is
+available, NULL is returned. The length of the name (excluding the terminating
+zero) is stored in the code unit that precedes the name. You should use this
+length instead of relying on the terminating zero if the name might contain a
+binary zero.
+.P
+After a successful match, the name that is returned is the last mark name
+encountered on the matching path through the pattern. Instances of backtracking
+verbs without names do not count. Thus, for example, if the matching path
+contains (*MARK:A)(*PRUNE), the name "A" is returned. After a "no match" or a
+partial match, the last encountered name is returned. For example, consider
+this pattern:
+.sp
+  ^(*MARK:A)((*MARK:B)a|b)c
+.sp
+When it matches "bc", the returned name is A. The B mark is "seen" in the first
+branch of the group, but it is not on the matching path. On the other hand,
+when this pattern fails to match "bx", the returned name is B.
+.P
+\fBWarning:\fP By default, certain start-of-match optimizations are used to
+give a fast "no match" result in some situations. For example, if the anchoring
+is removed from the pattern above, there is an initial check for the presence
+of "c" in the subject before running the matching engine. This check fails for
+"bx", causing a match failure without seeing any marks. You can disable the
+start-of-match optimizations by setting the PCRE2_NO_START_OPTIMIZE option for
+\fBpcre2_compile()\fP or by starting the pattern with (*NO_START_OPT).
+.P
+After a successful match, a partial match, or one of the invalid UTF errors
+(for example, PCRE2_ERROR_UTF8_ERR5), \fBpcre2_get_startchar()\fP can be
+called. After a successful or partial match it returns the code unit offset of
+the character at which the match started. For a non-partial match, this can be
+different to the value of \fIovector[0]\fP if the pattern contains the \eK
+escape sequence. After a partial match, however, this value is always the same
+as \fIovector[0]\fP because \eK does not affect the result of a partial match.

+substring zero is available. An attempt to extract any other substring gives
+the error PCRE2_ERROR_PARTIAL. The next section describes similar functions for
+extracting captured substrings by name.
+.P
+If a pattern uses the \eK escape sequence within a positive assertion, the
+reported start of a successful match can be greater than the end of the match.
+For example, if the pattern (?=ab\eK) is matched against "ab", the start and
+end offset values for the match are 2 and 0. In this situation, calling these
+functions with a zero substring number extracts a zero-length empty string.
+.P
+You can find the length in code units of a captured substring without
+extracting it by calling \fBpcre2_substring_length_bynumber()\fP. The first
+argument is a pointer to the match data block, the second is the group number,
+and the third is a pointer to a variable into which the length is placed. If
+you just want to know whether or not the substring has been captured, you can
+pass the third argument as NULL.
+.P
+The \fBpcre2_substring_copy_bynumber()\fP function copies a captured substring
+into a supplied buffer, whereas \fBpcre2_substring_get_bynumber()\fP copies it
+into new memory, obtained using the same memory allocation function that was
+used for the match data block. The first two arguments of these functions are a
+pointer to the match data block and a capture group number.
+.P
+The final arguments of \fBpcre2_substring_copy_bynumber()\fP are a pointer to
+the buffer and a pointer to a variable that contains its length in code units.
+This is updated to contain the actual number of code units used for the
+extracted substring, excluding the terminating zero.
+.P
+For \fBpcre2_substring_get_bynumber()\fP the third and fourth arguments point
+to variables that are updated with a pointer to the new memory and the number
+of code units that comprise the substring, again excluding the terminating
+zero. When the substring is no longer needed, the memory should be freed by
+calling \fBpcre2_substring_free()\fP.
+.P
+The return value from all these functions is zero for success, or a negative
+error code. If the pattern match failed, the match failure code is returned.
+If a substring number greater than zero is used after a partial match,
+PCRE2_ERROR_PARTIAL is returned. Other possible error codes are:
+.sp
+  PCRE2_ERROR_NOMEMORY
+.sp
+The buffer was too small for \fBpcre2_substring_copy_bynumber()\fP, or the
+attempt to get memory failed for \fBpcre2_substring_get_bynumber()\fP.
+.sp
+  PCRE2_ERROR_NOSUBSTRING
+.sp
+There is no substring with that number in the pattern, that is, the number is
+greater than the number of capturing parentheses.
+.sp
+  PCRE2_ERROR_UNAVAILABLE
+.sp
+The substring number, though not greater than the number of captures in the
+pattern, is greater than the number of slots in the ovector, so the substring
+could not be captured.
+.sp
+  PCRE2_ERROR_UNSET
+.sp
+The substring did not participate in the match. For example, if the pattern is
+(abc)|(def) and the subject is "def", and the ovector contains at least two
+capturing slots, substring number 1 is unset.

+could not be obtained. When the list is no longer needed, it should be freed by

+\fIn\fP has not been used at all, it returns an empty string. This can be

+Given the number, you can extract the substring directly from the ovector, or

+can be given as PCRE2_ZERO_TERMINATED for a zero-terminated string. As a

+replacement is assumed to be an empty string. If \fIrlength\fP is non-zero, an
+error occurs if \fIreplacement\fP is NULL.
+.P
+There is an option (see PCRE2_SUBSTITUTE_REPLACEMENT_ONLY below) to return just
+the replacement string(s). The default action is to perform just one
+replacement if the pattern matches, but there is an option that requests
+multiple replacements (see PCRE2_SUBSTITUTE_GLOBAL below).
+.P
+If successful, \fBpcre2_substitute()\fP returns the number of substitutions
+that were carried out. This may be zero if no match was found, and is never
+greater than one unless PCRE2_SUBSTITUTE_GLOBAL is set. A negative value is
+returned if an error is detected.
+.P
+Matches in which a \eK item in a lookahead in the pattern causes the match to
+end before it starts are not supported, and give rise to an error return. For
+global replacements, matches in which \eK in a lookbehind causes the match to
+start earlier than the point that was reached in the previous iteration are
+also not supported.
+.P
+The first seven arguments of \fBpcre2_substitute()\fP are the same as for
+\fBpcre2_match()\fP, except that the partial matching options are not
+permitted, and \fImatch_data\fP may be passed as NULL, in which case a match
+data block is obtained and freed within this function, using memory management
+functions from the match context, if provided, or else those that were used to
+allocate memory for the compiled code.
+.P
+If \fImatch_data\fP is not NULL and PCRE2_SUBSTITUTE_MATCHED is not set, the
+provided block is used for all calls to \fBpcre2_match()\fP, and its contents
+afterwards are the result of the final call. For global changes, this will
+always be a no-match error. The contents of the ovector within the match data
+block may or may not have been changed.
+.P
+As well as the usual options for \fBpcre2_match()\fP, a number of additional
+options can be set in the \fIoptions\fP argument of \fBpcre2_substitute()\fP.
+One such option is PCRE2_SUBSTITUTE_MATCHED. When this is set, an external
+\fImatch_data\fP block must be provided, and it must have already been used for
+an external call to \fBpcre2_match()\fP with the same pattern and subject
+arguments. The data in the \fImatch_data\fP block (return code, offset vector)
+is then used for the first substitution instead of calling \fBpcre2_match()\fP
+from within \fBpcre2_substitute()\fP. This allows an application to check for a
+match before choosing to substitute, without having to repeat the match.
+.P
+The contents of the externally supplied match data block are not changed when
+PCRE2_SUBSTITUTE_MATCHED is set. If PCRE2_SUBSTITUTE_GLOBAL is also set,
+\fBpcre2_match()\fP is called after the first substitution to check for further
+matches, but this is done using an internally obtained match data block, thus
+always leaving the external block unchanged.
+.P
+The \fIcode\fP argument is not used for matching before the first substitution
+when PCRE2_SUBSTITUTE_MATCHED is set, but it must be provided, even when
+PCRE2_SUBSTITUTE_GLOBAL is not set, because it contains information such as the
+UTF setting and the number of capturing parentheses in the pattern.
+.P
+The default action of \fBpcre2_substitute()\fP is to return a copy of the
+subject string with matched substrings replaced. However, if
+PCRE2_SUBSTITUTE_REPLACEMENT_ONLY is set, only the replacement substrings are
+returned. In the global case, multiple replacements are concatenated in the
+output buffer. Substitution callouts (see
+.\" HTML 
+.\" 
+below)
+.\"
+can be used to separate them if necessary.
+.P
+The \fIoutlengthptr\fP argument of \fBpcre2_substitute()\fP must point to a
+variable that contains the length, in code units, of the output buffer. If the
+function is successful, the value is updated to contain the length in code
+units of the new string, excluding the trailing zero that is automatically
+added.
+.P
+If the function is not successful, the value set via \fIoutlengthptr\fP depends
+on the type of error. For syntax errors in the replacement string, the value is
+the offset in the replacement string where the error was detected. For other
+errors, the value is PCRE2_UNSET by default. This includes the case of the
+output buffer being too small, unless PCRE2_SUBSTITUTE_OVERFLOW_LENGTH is set.
+.P
+PCRE2_SUBSTITUTE_OVERFLOW_LENGTH changes what happens when the output buffer is
+too small. The default action is to return PCRE2_ERROR_NOMEMORY immediately. If
+this option is set, however, \fBpcre2_substitute()\fP continues to go through
+the motions of matching and substituting (without, of course, writing anything)
+in order to compute the size of buffer that is needed. This value is passed
+back via the \fIoutlengthptr\fP variable, with the result of the function still
+being PCRE2_ERROR_NOMEMORY.
+.P
+Passing a buffer size of zero is a permitted way of finding out how much memory
+is needed for given substitution. However, this does mean that the entire
+operation is carried out twice. Depending on the application, it may be more
+efficient to allocate a large buffer and free the excess afterwards, instead of
+using PCRE2_SUBSTITUTE_OVERFLOW_LENGTH.
+.P
+The replacement string, which is interpreted as a UTF string in UTF mode, is
+checked for UTF validity unless PCRE2_NO_UTF_CHECK is set. An invalid UTF
+replacement string causes an immediate return with the relevant UTF error code.
+.P
+If PCRE2_SUBSTITUTE_LITERAL is set, the replacement string is not interpreted
+in any way. By default, however, a dollar character is an escape character that
+can specify the insertion of characters from capture groups and names from
+(*MARK) or other control verbs in the pattern. Dollar is the only escape
+character (backslash is treated as literal). The following forms are always
+recognized:
+.sp
+  $$                  insert a dollar character
+  $ or ${}      insert the contents of group 
+  $*MARK or ${*MARK}  insert a control verb name
+.sp
+Either a group number or a group name can be given for . Curly brackets are
+required only if the following character would be interpreted as part of the
+number or name. The number may be zero to include the entire matched string.
+For example, if the pattern a(b)c is matched with "=abc=" and the replacement
+string "+$1$0$1+", the result is "=+babcb+=".
+.P
+$*MARK inserts the name from the last encountered backtracking control verb on
+the matching path that has a name. (*MARK) must always include a name, but the
+other verbs need not. For example, in the case of (*MARK:A)(*PRUNE) the name
+inserted is "A", but for (*MARK:A)(*PRUNE:B) the relevant name is "B". This
+facility can be used to perform simple simultaneous substitutions, as this
+\fBpcre2test\fP example shows:
+.sp
+  /(*MARK:pear)apple|(*MARK:orange)lemon/g,replace=${*MARK}
+      apple lemon
+   2: pear orange
+.sp
+PCRE2_SUBSTITUTE_GLOBAL causes the function to iterate over the subject string,
+replacing every matching substring. If this option is not set, only the first
+matching substring is replaced. The search for matches takes place in the
+original subject string (that is, previous replacements do not affect it).
+Iteration is implemented by advancing the \fIstartoffset\fP value for each
+search, which is always passed the entire subject string. If an offset limit is
+set in the match context, searching stops when that limit is reached.
+.P
+You can restrict the effect of a global substitution to a portion of the
+subject string by setting either or both of \fIstartoffset\fP and an offset
+limit. Here is a \fBpcre2test\fP example:
+.sp
+  /B/g,replace=!,use_offset_limit
+  ABC ABC ABC ABC\e=offset=3,offset_limit=12
+   2: ABC A!C A!C ABC
+.sp
+When continuing with global substitutions after matching a substring with zero
+length, an attempt to find a non-empty match at the same offset is performed.
+If this is not successful, the offset is advanced by one character except when
+CRLF is a valid newline sequence and the next two characters are CR, LF. In
+this case, the offset is advanced by two characters.
+.P
+PCRE2_SUBSTITUTE_UNKNOWN_UNSET causes references to capture groups that do
+not appear in the pattern to be treated as unset groups. This option should be
+used with care, because it means that a typo in a group name or number no
+longer causes the PCRE2_ERROR_NOSUBSTRING error.
+.P
+PCRE2_SUBSTITUTE_UNSET_EMPTY causes unset capture groups (including unknown
+groups when PCRE2_SUBSTITUTE_UNKNOWN_UNSET is set) to be treated as empty
+strings when inserted as described above. If this option is not set, an attempt
+to insert an unset group causes the PCRE2_ERROR_UNSET error. This option does
+not influence the extended substitution syntax described below.
+.P
+PCRE2_SUBSTITUTE_EXTENDED causes extra processing to be applied to the
+replacement string. Without this option, only the dollar character is special,
+and only the group insertion forms listed above are valid. When
+PCRE2_SUBSTITUTE_EXTENDED is set, two things change:
+.P
+Firstly, backslash in a replacement string is interpreted as an escape
+character. The usual forms such as \en or \ex{ddd} can be used to specify
+particular character codes, and backslash followed by any non-alphanumeric
+character quotes that character. Extended quoting can be coded using \eQ...\eE,
+exactly as in pattern strings.
+.P
+There are also four escape sequences for forcing the case of inserted letters.
+The insertion mechanism has three states: no case forcing, force upper case,
+and force lower case. The escape sequences change the current state: \eU and
+\eL change to upper or lower case forcing, respectively, and \eE (when not
+terminating a \eQ quoted sequence) reverts to no case forcing. The sequences
+\eu and \el force the next character (if it is a letter) to upper or lower
+case, respectively, and then the state automatically reverts to no case
+forcing. Case forcing applies to all inserted characters, including those from
+capture groups and letters within \eQ...\eE quoted sequences. If either
+PCRE2_UTF or PCRE2_UCP was set when the pattern was compiled, Unicode
+properties are used for case forcing characters whose code points are greater
+than 127.
+.P
+Note that case forcing sequences such as \eU...\eE do not nest. For example,
+the result of processing "\eUaa\eLBB\eEcc\eE" is "AAbbcc"; the final \eE has no
+effect. Note also that the PCRE2_ALT_BSUX and PCRE2_EXTRA_ALT_BSUX options do
+not apply to replacement strings.
+.P
+The second effect of setting PCRE2_SUBSTITUTE_EXTENDED is to add more
+flexibility to capture group substitution. The syntax is similar to that used
+by Bash:
+.sp
+  ${:-}
+  ${:+:}
+.sp
+As before,  may be a group number or a name. The first form specifies a
+default value. If group  is set, its value is inserted; if not,  is
+expanded and the result inserted. The second form specifies strings that are
+expanded and inserted when group  is set or unset, respectively. The first
+form is just a convenient shorthand for
+.sp
+  ${:+${}:}
+.sp
+Backslash can be used to escape colons and closing curly brackets in the
+replacement strings. A change of the case forcing state within a replacement
+string remains in force afterwards, as shown in this \fBpcre2test\fP example:
+.sp
+  /(some)?(body)/substitute_extended,replace=${1:+\eU:\eL}HeLLo
+      body
+   1: hello
+      somebody
+   1: HELLO
+.sp
+The PCRE2_SUBSTITUTE_UNSET_EMPTY option does not affect these extended
+substitutions. However, PCRE2_SUBSTITUTE_UNKNOWN_UNSET does cause unknown
+groups in the extended syntax forms to be treated as unset.
+.P
+If PCRE2_SUBSTITUTE_LITERAL is set, PCRE2_SUBSTITUTE_UNKNOWN_UNSET,
+PCRE2_SUBSTITUTE_UNSET_EMPTY, and PCRE2_SUBSTITUTE_EXTENDED are irrelevant and
+are ignored.
+.

+name, or PCRE2_ERROR_NOUNIQUESUBSTRING otherwise.
+.P
+When the third and fourth arguments are not NULL, they must be pointers to
+variables that are updated by the function. After it has run, they point to the
+first and last entries in the name-to-number table for the given name, and the
+function returns the length of each entry in code units. In both cases,
+PCRE2_ERROR_NOSUBSTRING is returned if there are no entries for the given name.
+.P
+The format of the name table is described
+.\" HTML

+in the section entitled \fIInformation about a pattern\fP. Given all the

+the captured data.
+.
+.
+.SH "FINDING ALL POSSIBLE MATCHES AT ONE POSITION"
+.rs
+.sp
+The traditional matching function uses a similar algorithm to Perl, which stops
+when it finds the first match at a given point in the subject. If you want to
+find all possible matches, or the longest possible match at a given position,
+consider using the alternative matching function (see below) instead. If you
+cannot use the alternative function, you can kludge it up by making use of the
+callout facility, which is described in the
+.\" HREF
+\fBpcre2callout\fP
+.\"
+documentation.
+.P
+What you have to do is to insert a callout right at the end of the pattern.
+When your callout function is called, extract and save the current matched
+substring. Then return 1, which forces \fBpcre2_match()\fP to backtrack and try
+other alternatives. Ultimately, when it runs out of matches,
+\fBpcre2_match()\fP will yield PCRE2_ERROR_NOMATCH.

+.P
+The function \fBpcre2_dfa_match()\fP is called to match a subject string
+against a compiled pattern, using a matching algorithm that scans the subject
+string just once (not counting lookaround assertions), and does not backtrack
+(except when processing lookaround assertions). This has different
+characteristics to the normal algorithm, and is not compatible with Perl. Some
+of the features of PCRE2 patterns are not supported. Nevertheless, there are
+times when this kind of matching can be useful. For a discussion of the two
+matching algorithms, and a list of features that \fBpcre2_dfa_match()\fP does
+not support, see the
+.\" HREF
+\fBpcre2matching\fP
+.\"
+documentation.
+.P
+The arguments for the \fBpcre2_dfa_match()\fP function are the same as for
+\fBpcre2_match()\fP, plus two extras. The ovector within the match data block
+is used in a different way, and this is described below. The other common
+arguments are used in the same way as for \fBpcre2_match()\fP, so their
+description is not repeated here.
+.P
+The two additional arguments provide workspace for the function. The workspace
+vector should contain at least 20 elements. It is used for keeping track of
+multiple paths through the pattern tree. More workspace is needed for patterns
+and subjects where there are a lot of potential matches.
+.P
+Here is an example of a simple call to \fBpcre2_dfa_match()\fP:
+.sp
+  int wspace[20];
+  pcre2_match_data *md = pcre2_match_data_create(4, NULL);
+  int rc = pcre2_dfa_match(
+    re,             /* result of pcre2_compile() */
+    "some string",  /* the subject string */
+    11,             /* the length of the subject string */
+    0,              /* start at offset 0 in the subject */
+    0,              /* default options */
+    md,             /* the match data block */
+    NULL,           /* a match context; NULL means use defaults */
+    wspace,         /* working space vector */
+    20);            /* number of elements (NOT size in bytes) */
+.
+.SS "Option bits for \fBpcre2_dfa_match()\fP"
+.rs
+.sp
+The unused bits of the \fIoptions\fP argument for \fBpcre2_dfa_match()\fP must
+be zero. The only bits that may be set are PCRE2_ANCHORED,
+PCRE2_COPY_MATCHED_SUBJECT, PCRE2_ENDANCHORED, PCRE2_NOTBOL, PCRE2_NOTEOL,
+PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART, PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD,
+PCRE2_PARTIAL_SOFT, PCRE2_DFA_SHORTEST, and PCRE2_DFA_RESTART. All but the last
+four of these are exactly the same as for \fBpcre2_match()\fP, so their
+description is not repeated here.
+.sp
+  PCRE2_PARTIAL_HARD
+  PCRE2_PARTIAL_SOFT
+.sp
+These have the same general effect as they do for \fBpcre2_match()\fP, but the
+details are slightly different. When PCRE2_PARTIAL_HARD is set for
+\fBpcre2_dfa_match()\fP, it returns PCRE2_ERROR_PARTIAL if the end of the
+subject is reached and there is still at least one matching possibility that
+requires additional characters. This happens even if some complete matches have
+already been found. When PCRE2_PARTIAL_SOFT is set, the return code
+PCRE2_ERROR_NOMATCH is converted into PCRE2_ERROR_PARTIAL if the end of the
+subject is reached, there have been no complete matches, but there is still at
+least one matching possibility. The portion of the string that was inspected
+when the longest partial match was found is set as the first matching string in
+both cases. There is a more detailed discussion of partial and multi-segment
+matching, with examples, in the
+.\" HREF
+\fBpcre2partial\fP
+.\"
+documentation.
+.sp
+  PCRE2_DFA_SHORTEST
+.sp
+Setting the PCRE2_DFA_SHORTEST option causes the matching algorithm to stop as
+soon as it has found one match. Because of the way the alternative algorithm
+works, this is necessarily the shortest possible match at the first possible
+matching point in the subject string.
+.sp
+  PCRE2_DFA_RESTART
+.sp
+When \fBpcre2_dfa_match()\fP returns a partial match, it is possible to call it
+again, with additional subject characters, and have it continue with the same
+match. The PCRE2_DFA_RESTART option requests this action; when it is set, the
+\fIworkspace\fP and \fIwscount\fP options must reference the same vector as
+before because data about the match so far is left in them after a partial
+match. There is more discussion of this facility in the
+.\" HREF
+\fBpcre2partial\fP
+.\"
+documentation.
+.
+.
+.SS "Successful returns from \fBpcre2_dfa_match()\fP"
+.rs
+.sp
+When \fBpcre2_dfa_match()\fP succeeds, it may have matched more than one
+substring in the subject. Note, however, that all the matches from one run of
+the function start at the same point in the subject. The shorter matches are
+all initial substrings of the longer matches. For example, if the pattern
+.sp
+  <.*>
+.sp
+is matched against the string
+.sp
+  This is    no more
+.sp
+the three matched strings are
+.sp
+    
+   
+  
+.sp
+On success, the yield of the function is a number greater than zero, which is
+the number of matched substrings. The offsets of the substrings are returned in
+the ovector, and can be extracted by number in the same way as for
+\fBpcre2_match()\fP, but the numbers bear no relation to any capture groups
+that may exist in the pattern, because DFA matching does not support capturing.
+.P
+Calls to the convenience functions that extract substrings by name
+return the error PCRE2_ERROR_DFA_UFUNC (unsupported function) if used after a
+DFA match. The convenience functions that extract substrings by number never
+return PCRE2_ERROR_NOSUBSTRING.
+.P
+The matched strings are stored in the ovector in reverse order of length; that
+is, the longest matching string is first. If there were too many matches to fit
+into the ovector, the yield of the function is zero, and the vector is filled
+with the longest matches.
+.P
+NOTE: PCRE2's "auto-possessification" optimization usually applies to character
+repeats at the end of a pattern (as well as internally). For example, the
+pattern "a\ed+" is compiled as if it were "a\ed++". For DFA matching, this
+means that only one possible match is found. If you really do want multiple
+matches in such cases, either use an ungreedy repeat such as "a\ed+?" or set
+the PCRE2_NO_AUTO_POSSESS option when compiling.
+.
+.
+.SS "Error returns from \fBpcre2_dfa_match()\fP"
+.rs
+.sp
+The \fBpcre2_dfa_match()\fP function returns a negative number when it fails.
+Many of the errors are the same as for \fBpcre2_match()\fP, as described
+.\" HTML 
+.\" 
+above.
+.\"
+There are in addition the following errors that are specific to
+\fBpcre2_dfa_match()\fP:
+.sp
+  PCRE2_ERROR_DFA_UITEM
+.sp
+This return is given if \fBpcre2_dfa_match()\fP encounters an item in the
+pattern that it does not support, for instance, the use of \eC in a UTF mode or
+a backreference.
+.sp
+  PCRE2_ERROR_DFA_UCOND
+.sp
+This return is given if \fBpcre2_dfa_match()\fP encounters a condition item
+that uses a backreference for the condition, or a test for recursion in a
+specific capture group. These are not supported.
+.sp
+  PCRE2_ERROR_DFA_UINVALID_UTF
+.sp
+This return is given if \fBpcre2_dfa_match()\fP is called for a pattern that
+was compiled with PCRE2_MATCH_INVALID_UTF. This is not supported for DFA
+matching.
+.sp
+  PCRE2_ERROR_DFA_WSSIZE
+.sp
+This return is given if \fBpcre2_dfa_match()\fP runs out of space in the
+\fIworkspace\fP vector.
+.sp
+  PCRE2_ERROR_DFA_RECURSE
+.sp
+When a recursion or subroutine call is processed, the matching function calls
+itself recursively, using private memory for the ovector and \fIworkspace\fP.
+This error is given if the internal ovector is not large enough. This should be
+extremely rare, as a vector of size 1000 is used.
+.sp
+  PCRE2_ERROR_DFA_BADRESTART
+.sp
+When \fBpcre2_dfa_match()\fP is called with the \fBPCRE2_DFA_RESTART\fP option,
+some plausibility checks are made on the contents of the workspace, which
+should contain data about the previous partial match. If any of these checks
+fail, this error is given.

+.SH "BUILDING PCRE2"
+.rs
+.sp
+PCRE2 is distributed with a \fBconfigure\fP script that can be used to build
+the library in Unix-like environments using the applications known as
+Autotools. Also in the distribution are files to support building using
+\fBCMake\fP instead of \fBconfigure\fP. The text file
+.\" HTML 
+.\" 
+\fBREADME\fP
+.\"
+contains general information about building with Autotools (some of which is
+repeated below), and also has some comments about building on various operating
+systems. The files in the \fBvms\fP directory support building under OpenVMS.
+There is a lot more information about building PCRE2 without using
+Autotools (including information about using \fBCMake\fP and building "by
+hand") in the text file called
+.\" HTML 
+.\" 
+\fBNON-AUTOTOOLS-BUILD\fP.
+.\"
+You should consult this file as well as the
+.\" HTML 
+.\" 
+\fBREADME\fP
+.\"
+file if you are building in a non-Unix-like environment.
+.
+.
+.SH "PCRE2 BUILD-TIME OPTIONS"
+.rs
+.sp
+The rest of this document describes the optional features of PCRE2 that can be
+selected when the library is compiled. It assumes use of the \fBconfigure\fP
+script, where the optional features are selected or deselected by providing
+options to \fBconfigure\fP before running the \fBmake\fP command. However, the
+same options can be selected in both Unix-like and non-Unix-like environments
+if you are using \fBCMake\fP instead of \fBconfigure\fP to build PCRE2.
+.P
+If you are not using Autotools or \fBCMake\fP, option selection can be done by
+editing the \fBconfig.h\fP file, or by passing parameter settings to the
+compiler, as described in
+.\" HTML 
+.\" 
+\fBNON-AUTOTOOLS-BUILD\fP.
+.\"
+.P
+The complete list of options for \fBconfigure\fP (which includes the standard
+ones such as the selection of the installation directory) can be obtained by
+running
+.sp
+  ./configure --help
+.sp
+The following sections include descriptions of "on/off" options whose names
+begin with --enable or --disable. Because of the way that \fBconfigure\fP
+works, --enable and --disable always come in pairs, so the complementary option
+always exists as well, but as it specifies the default, it is not described.
+Options that specify values have names that start with --with. At the end of a
+\fBconfigure\fP run, a summary of the configuration is output.
+.
+.
+.SH "BUILDING 8-BIT, 16-BIT AND 32-BIT LIBRARIES"
+.rs
+.sp
+By default, a library called \fBlibpcre2-8\fP is built, containing functions
+that take string arguments contained in arrays of bytes, interpreted either as
+single-byte characters, or UTF-8 strings. You can also build two other
+libraries, called \fBlibpcre2-16\fP and \fBlibpcre2-32\fP, which process
+strings that are contained in arrays of 16-bit and 32-bit code units,
+respectively. These can be interpreted either as single-unit characters or
+UTF-16/UTF-32 strings. To build these additional libraries, add one or both of
+the following to the \fBconfigure\fP command:
+.sp
+  --enable-pcre2-16
+  --enable-pcre2-32
+.sp
+If you do not want the 8-bit library, add
+.sp
+  --disable-pcre2-8
+.sp
+as well. At least one of the three libraries must be built. Note that the POSIX
+wrapper is for the 8-bit library only, and that \fBpcre2grep\fP is an 8-bit
+program. Neither of these are built if you select only the 16-bit or 32-bit
+libraries.
+.
+.
+.SH "BUILDING SHARED AND STATIC LIBRARIES"
+.rs
+.sp
+The Autotools PCRE2 building process uses \fBlibtool\fP to build both shared
+and static libraries by default. You can suppress an unwanted library by adding
+one of
+.sp
+  --disable-shared
+  --disable-static
+.sp
+to the \fBconfigure\fP command. Setting --disable-shared ensures that PCRE2
+libraries are built as static libraries. The binaries that are then created as
+part of the build process (for example, \fBpcre2test\fP and \fBpcre2grep\fP)
+are linked statically with one or more PCRE2 libraries, but may also be
+dynamically linked with other libraries such as \fBlibc\fP. If you want these
+binaries to be fully statically linked, you can set LDFLAGS like this:
+.sp
+LDFLAGS=--static ./configure --disable-shared
+.sp
+Note the two hyphens in --static. Of course, this works only if static versions
+of all the relevant libraries are available for linking.
+.
+.
+.SH "UNICODE AND UTF SUPPORT"
+.rs
+.sp
+By default, PCRE2 is built with support for Unicode and UTF character strings.
+To build it without Unicode support, add
+.sp
+  --disable-unicode
+.sp
+to the \fBconfigure\fP command. This setting applies to all three libraries. It
+is not possible to build one library with Unicode support and another without
+in the same configuration.
+.P
+Of itself, Unicode support does not make PCRE2 treat strings as UTF-8, UTF-16
+or UTF-32. To do that, applications that use the library can set the PCRE2_UTF
+option when they call \fBpcre2_compile()\fP to compile a pattern.
+Alternatively, patterns may be started with (*UTF) unless the application has
+locked this out by setting PCRE2_NEVER_UTF.
+.P
+UTF support allows the libraries to process character code points up to
+0x10ffff in the strings that they handle. Unicode support also gives access to
+the Unicode properties of characters, using pattern escapes such as \eP, \ep,
+and \eX. Only the general category properties such as \fILu\fP and \fINd\fP,
+script names, and some bi-directional properties are supported. Details are
+given in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation.
+.P
+Pattern escapes such as \ed and \ew do not by default make use of Unicode
+properties. The application can request that they do by setting the PCRE2_UCP
+option. Unless the application has set PCRE2_NEVER_UCP, a pattern may also
+request this by starting with (*UCP).
+.
+.
+.SH "DISABLING THE USE OF \eC"
+.rs
+.sp
+The \eC escape sequence, which matches a single code unit, even in a UTF mode,
+can cause unpredictable behaviour because it may leave the current matching
+point in the middle of a multi-code-unit character. The application can lock it
+out by setting the PCRE2_NEVER_BACKSLASH_C option when calling
+\fBpcre2_compile()\fP. There is also a build-time option
+.sp
+  --enable-never-backslash-C
+.sp
+(note the upper case C) which locks out the use of \eC entirely.
+.
+.
+.SH "JUST-IN-TIME COMPILER SUPPORT"
+.rs
+.sp
+Just-in-time (JIT) compiler support is included in the build by specifying
+.sp
+  --enable-jit
+.sp
+This support is available only for certain hardware architectures. If this
+option is set for an unsupported architecture, a building error occurs.
+If in doubt, use
+.sp
+  --enable-jit=auto
+.sp
+which enables JIT only if the current hardware is supported. You can check
+if JIT is enabled in the configuration summary that is output at the end of a
+\fBconfigure\fP run. If you are enabling JIT under SELinux you may also want to
+add
+.sp
+  --enable-jit-sealloc
+.sp
+which enables the use of an execmem allocator in JIT that is compatible with
+SELinux. This has no effect if JIT is not enabled. See the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation for a discussion of JIT usage. When JIT support is enabled,
+\fBpcre2grep\fP automatically makes use of it, unless you add
+.sp
+  --disable-pcre2grep-jit
+.sp
+to the \fBconfigure\fP command.
+.
+.
+.SH "NEWLINE RECOGNITION"
+.rs
+.sp
+By default, PCRE2 interprets the linefeed (LF) character as indicating the end
+of a line. This is the normal newline character on Unix-like systems. You can
+compile PCRE2 to use carriage return (CR) instead, by adding
+.sp
+  --enable-newline-is-cr
+.sp
+to the \fBconfigure\fP command. There is also an --enable-newline-is-lf option,
+which explicitly specifies linefeed as the newline character.
+.P
+Alternatively, you can specify that line endings are to be indicated by the
+two-character sequence CRLF (CR immediately followed by LF). If you want this,
+add
+.sp
+  --enable-newline-is-crlf
+.sp
+to the \fBconfigure\fP command. There is a fourth option, specified by
+.sp
+  --enable-newline-is-anycrlf
+.sp
+which causes PCRE2 to recognize any of the three sequences CR, LF, or CRLF as
+indicating a line ending. A fifth option, specified by
+.sp
+  --enable-newline-is-any
+.sp
+causes PCRE2 to recognize any Unicode newline sequence. The Unicode newline
+sequences are the three just mentioned, plus the single characters VT (vertical
+tab, U+000B), FF (form feed, U+000C), NEL (next line, U+0085), LS (line
+separator, U+2028), and PS (paragraph separator, U+2029). The final option is
+.sp
+  --enable-newline-is-nul
+.sp
+which causes NUL (binary zero) to be set as the default line-ending character.
+.P
+Whatever default line ending convention is selected when PCRE2 is built can be
+overridden by applications that use the library. At build time it is
+recommended to use the standard for your operating system.
+.
+.
+.SH "WHAT \eR MATCHES"
+.rs
+.sp
+By default, the sequence \eR in a pattern matches any Unicode newline sequence,
+independently of what has been selected as the line ending sequence. If you
+specify
+.sp
+  --enable-bsr-anycrlf
+.sp
+the default is changed so that \eR matches only CR, LF, or CRLF. Whatever is
+selected when PCRE2 is built can be overridden by applications that use the
+library.
+.
+.
+.SH "HANDLING VERY LARGE PATTERNS"
+.rs
+.sp
+Within a compiled pattern, offset values are used to point from one part to
+another (for example, from an opening parenthesis to an alternation
+metacharacter). By default, in the 8-bit and 16-bit libraries, two-byte values
+are used for these offsets, leading to a maximum size for a compiled pattern of
+around 64 thousand code units. This is sufficient to handle all but the most
+gigantic patterns. Nevertheless, some people do want to process truly enormous
+patterns, so it is possible to compile PCRE2 to use three-byte or four-byte
+offsets by adding a setting such as
+.sp
+  --with-link-size=3
+.sp
+to the \fBconfigure\fP command. The value given must be 2, 3, or 4. For the
+16-bit library, a value of 3 is rounded up to 4. In these libraries, using
+longer offsets slows down the operation of PCRE2 because it has to load
+additional data when handling them. For the 32-bit library the value is always
+4 and cannot be overridden; the value of --with-link-size is ignored.
+.
+.
+.SH "LIMITING PCRE2 RESOURCE USAGE"
+.rs
+.sp
+The \fBpcre2_match()\fP function increments a counter each time it goes round
+its main loop. Putting a limit on this counter controls the amount of computing
+resource used by a single call to \fBpcre2_match()\fP. The limit can be changed
+at run time, as described in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation. The default is 10 million, but this can be changed by adding a
+setting such as
+.sp
+  --with-match-limit=500000
+.sp
+to the \fBconfigure\fP command. This setting also applies to the
+\fBpcre2_dfa_match()\fP matching function, and to JIT matching (though the
+counting is done differently).
+.P
+The \fBpcre2_match()\fP function uses heap memory to record backtracking
+points. The more nested backtracking points there are (that is, the deeper the
+search tree), the more memory is needed. There is an upper limit, specified in
+kibibytes (units of 1024 bytes). This limit can be changed at run time, as
+described in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation. The default limit (in effect unlimited) is 20 million. You can
+change this by a setting such as
+.sp
+  --with-heap-limit=500
+.sp
+which limits the amount of heap to 500 KiB. This limit applies only to
+interpretive matching in \fBpcre2_match()\fP and \fBpcre2_dfa_match()\fP, which
+may also use the heap for internal workspace when processing complicated
+patterns. This limit does not apply when JIT (which has its own memory
+arrangements) is used.
+.P
+You can also explicitly limit the depth of nested backtracking in the
+\fBpcre2_match()\fP interpreter. This limit defaults to the value that is set
+for --with-match-limit. You can set a lower default limit by adding, for
+example,
+.sp
+  --with-match-limit-depth=10000
+.sp
+to the \fBconfigure\fP command. This value can be overridden at run time. This
+depth limit indirectly limits the amount of heap memory that is used, but
+because the size of each backtracking "frame" depends on the number of
+capturing parentheses in a pattern, the amount of heap that is used before the
+limit is reached varies from pattern to pattern. This limit was more useful in
+versions before 10.30, where function recursion was used for backtracking.
+.P
+As well as applying to \fBpcre2_match()\fP, the depth limit also controls
+the depth of recursive function calls in \fBpcre2_dfa_match()\fP. These are
+used for lookaround assertions, atomic groups, and recursion within patterns.
+The limit does not apply to JIT matching.
+.
+.
+.SH "LIMITING VARIABLE-LENGTH LOOKBEHIND ASSERTIONS"
+.rs
+.sp
+Lookbehind assertions in which one or more branches can match a variable number
+of characters are supported only if there is a maximum matching length for each
+top-level branch. There is a limit to this maximum that defaults to 255
+characters. You can alter this default by a setting such as
+.sp
+  --with-max-varlookbehind=100
+.sp
+The limit can be changed at runtime by calling
+\fBpcre2_set_max_varlookbehind()\fP. Lookbehind assertions in which every
+branch matches a fixed number of characters (not necessarily all the same) are
+not constrained by this limit.
+.
+.
+.\" HTML 
+.SH "CREATING CHARACTER TABLES AT BUILD TIME"
+.rs
+.sp
+PCRE2 uses fixed tables for processing characters whose code points are less
+than 256. By default, PCRE2 is built with a set of tables that are distributed
+in the file \fIsrc/pcre2_chartables.c.dist\fP. These tables are for ASCII codes
+only. If you add
+.sp
+  --enable-rebuild-chartables
+.sp
+to the \fBconfigure\fP command, the distributed tables are no longer used.
+Instead, a program called \fBpcre2_dftables\fP is compiled and run. This
+outputs the source for new set of tables, created in the default locale of your
+C run-time system. This method of replacing the tables does not work if you are
+cross compiling, because \fBpcre2_dftables\fP needs to be run on the local
+host and therefore not compiled with the cross compiler.
+.P
+If you need to create alternative tables when cross compiling, you will have to
+do so "by hand". There may also be other reasons for creating tables manually.
+To cause \fBpcre2_dftables\fP to be built on the local host, run a normal
+compiling command, and then run the program with the output file as its
+argument, for example:
+.sp
+  cc src/pcre2_dftables.c -o pcre2_dftables
+  ./pcre2_dftables src/pcre2_chartables.c
+.sp
+This builds the tables in the default locale of the local host. If you want to
+specify a locale, you must use the -L option:
+.sp
+  LC_ALL=fr_FR ./pcre2_dftables -L src/pcre2_chartables.c
+.sp
+You can also specify -b (with or without -L). This causes the tables to be
+written in binary instead of as source code. A set of binary tables can be
+loaded into memory by an application and passed to \fBpcre2_compile()\fP in the
+same way as tables created by calling \fBpcre2_maketables()\fP. The tables are
+just a string of bytes, independent of hardware characteristics such as
+endianness. This means they can be bundled with an application that runs in
+different environments, to ensure consistent behaviour.
+.
+.
+.SH "USING EBCDIC CODE"
+.rs
+.sp
+PCRE2 assumes by default that it will run in an environment where the character
+code is ASCII or Unicode, which is a superset of ASCII. This is the case for
+most computer operating systems. PCRE2 can, however, be compiled to run in an
+8-bit EBCDIC environment by adding
+.sp
+  --enable-ebcdic --disable-unicode
+.sp
+to the \fBconfigure\fP command. This setting implies
+--enable-rebuild-chartables. You should only use it if you know that you are in
+an EBCDIC environment (for example, an IBM mainframe operating system).
+.P
+It is not possible to support both EBCDIC and UTF-8 codes in the same version
+of the library. Consequently, --enable-unicode and --enable-ebcdic are mutually
+exclusive.
+.P
+The EBCDIC character that corresponds to an ASCII LF is assumed to have the
+value 0x15 by default. However, in some EBCDIC environments, 0x25 is used. In
+such an environment you should use
+.sp
+  --enable-ebcdic-nl25
+.sp
+as well as, or instead of, --enable-ebcdic. The EBCDIC character for CR has the
+same value as in ASCII, namely, 0x0d. Whichever of 0x15 and 0x25 is \fInot\fP
+chosen as LF is made to correspond to the Unicode NEL character (which, in
+Unicode, is 0x85).
+.P
+The options that select newline behaviour, such as --enable-newline-is-cr,
+and equivalent run-time options, refer to these character values in an EBCDIC
+environment.
+.
+.
+.SH "PCRE2GREP SUPPORT FOR EXTERNAL SCRIPTS"
+.rs
+.sp
+By default \fBpcre2grep\fP supports the use of callouts with string arguments
+within the patterns it is matching. There are two kinds: one that generates
+output using local code, and another that calls an external program or script.
+If --disable-pcre2grep-callout-fork is added to the \fBconfigure\fP command,
+only the first kind of callout is supported; if --disable-pcre2grep-callout is
+used, all callouts are completely ignored. For more details of \fBpcre2grep\fP
+callouts, see the
+.\" HREF
+\fBpcre2grep\fP
+.\"
+documentation.
+.
+.
+.SH "PCRE2GREP OPTIONS FOR COMPRESSED FILE SUPPORT"
+.rs
+.sp
+By default, \fBpcre2grep\fP reads all files as plain text. You can build it so
+that it recognizes files whose names end in \fB.gz\fP or \fB.bz2\fP, and reads
+them with \fBlibz\fP or \fBlibbz2\fP, respectively, by adding one or both of
+.sp
+  --enable-pcre2grep-libz
+  --enable-pcre2grep-libbz2
+.sp
+to the \fBconfigure\fP command. These options naturally require that the
+relevant libraries are installed on your system. Configuration will fail if
+they are not.
+.
+.
+.SH "PCRE2GREP BUFFER SIZE"
+.rs
+.sp
+\fBpcre2grep\fP uses an internal buffer to hold a "window" on the file it is
+scanning, in order to be able to output "before" and "after" lines when it
+finds a match. The default starting size of the buffer is 20KiB. The buffer
+itself is three times this size, but because of the way it is used for holding
+"before" lines, the longest line that is guaranteed to be processable is the
+notional buffer size. If a longer line is encountered, \fBpcre2grep\fP
+automatically expands the buffer, up to a specified maximum size, whose default
+is 1MiB or the starting size, whichever is the larger. You can change the
+default parameter values by adding, for example,
+.sp
+  --with-pcre2grep-bufsize=51200
+  --with-pcre2grep-max-bufsize=2097152
+.sp
+to the \fBconfigure\fP command. The caller of \fBpcre2grep\fP can override
+these values by using --buffer-size and --max-buffer-size on the command line.
+.
+.
+.SH "PCRE2TEST OPTION FOR LIBREADLINE SUPPORT"
+.rs
+.sp
+If you add one of
+.sp
+  --enable-pcre2test-libreadline
+  --enable-pcre2test-libedit
+.sp
+to the \fBconfigure\fP command, \fBpcre2test\fP is linked with the
+\fBlibreadline\fP or\fBlibedit\fP library, respectively, and when its input is
+from a terminal, it reads it using the \fBreadline()\fP function. This provides
+line-editing and history facilities. Note that \fBlibreadline\fP is
+GPL-licensed, so if you distribute a binary of \fBpcre2test\fP linked in this
+way, there may be licensing issues. These can be avoided by linking instead
+with \fBlibedit\fP, which has a BSD licence.
+.P
+Setting --enable-pcre2test-libreadline causes the \fB-lreadline\fP option to be
+added to the \fBpcre2test\fP build. In many operating environments with a
+system-installed readline library this is sufficient. However, in some
+environments (e.g. if an unmodified distribution version of readline is in
+use), some extra configuration may be necessary. The INSTALL file for
+\fBlibreadline\fP says this:
+.sp
+  "Readline uses the termcap functions, but does not link with
+  the termcap or curses library itself, allowing applications
+  which link with readline the to choose an appropriate library."
+.sp
+If your environment has not been set up so that an appropriate library is
+automatically included, you may need to add something like
+.sp
+  LIBS="-ncurses"
+.sp
+immediately before the \fBconfigure\fP command.
+.
+.
+.SH "INCLUDING DEBUGGING CODE"
+.rs
+.sp
+If you add
+.sp
+  --enable-debug
+.sp
+to the \fBconfigure\fP command, additional debugging code is included in the
+build. This feature is intended for use by the PCRE2 maintainers.
+.
+.
+.SH "DEBUGGING WITH VALGRIND SUPPORT"
+.rs
+.sp
+If you add
+.sp
+  --enable-valgrind
+.sp
+to the \fBconfigure\fP command, PCRE2 will use valgrind annotations to mark
+certain memory regions as unaddressable. This allows it to detect invalid
+memory accesses, and is mostly useful for debugging PCRE2 itself.
+.
+.
+.SH "CODE COVERAGE REPORTING"
+.rs
+.sp
+If your C compiler is gcc, you can build a version of PCRE2 that can generate a
+code coverage report for its test suite. To enable this, you must install
+\fBlcov\fP version 1.6 or above. Then specify
+.sp
+  --enable-coverage
+.sp
+to the \fBconfigure\fP command and build PCRE2 in the usual way.
+.P
+Note that using \fBccache\fP (a caching C compiler) is incompatible with code
+coverage reporting. If you have configured \fBccache\fP to run automatically
+on your system, you must set the environment variable
+.sp
+  CCACHE_DISABLE=1
+.sp
+before running \fBmake\fP to build PCRE2, so that \fBccache\fP is not used.
+.P
+When --enable-coverage is used, the following addition targets are added to the
+\fIMakefile\fP:
+.sp
+  make coverage
+.sp
+This creates a fresh coverage report for the PCRE2 test suite. It is equivalent
+to running "make coverage-reset", "make coverage-baseline", "make check", and
+then "make coverage-report".
+.sp
+  make coverage-reset
+.sp
+This zeroes the coverage counters, but does nothing else.
+.sp
+  make coverage-baseline
+.sp
+This captures baseline coverage information.
+.sp
+  make coverage-report
+.sp
+This creates the coverage report.
+.sp
+  make coverage-clean-report
+.sp
+This removes the generated coverage report without cleaning the coverage data
+itself.
+.sp
+  make coverage-clean-data
+.sp
+This removes the captured coverage data without removing the coverage files
+created at compile time (*.gcno).
+.sp
+  make coverage-clean
+.sp
+This cleans all coverage data including the generated coverage report. For more
+information about code coverage, see the \fBgcov\fP and \fBlcov\fP
+documentation.
+.
+.
+.SH "DISABLING THE Z AND T FORMATTING MODIFIERS"
+.rs
+.sp
+The C99 standard defines formatting modifiers z and t for size_t and
+ptrdiff_t values, respectively. By default, PCRE2 uses these modifiers in
+environments other than old versions of Microsoft Visual Studio when
+__STDC_VERSION__ is defined and has a value greater than or equal to 199901L
+(indicating support for C99).
+However, there is at least one environment that claims to be C99 but does not
+support these modifiers. If
+.sp
+  --disable-percent-zt
+.sp
+is specified, no use is made of the z or t modifiers. Instead of %td or %zu,
+a suitable format is used depending in the size of long for the platform.
+.
+.
+.SH "SUPPORT FOR FUZZERS"
+.rs
+.sp
+There is a special option for use by people who want to run fuzzing tests on
+PCRE2:
+.sp
+  --enable-fuzz-support
+.sp
+At present this applies only to the 8-bit library. If set, it causes an extra
+library called libpcre2-fuzzsupport.a to be built, but not installed. This
+contains a single function called LLVMFuzzerTestOneInput() whose arguments are
+a pointer to a string and the length of the string. When called, this function
+tries to compile the string as a pattern, and if that succeeds, to match it.
+This is done both with no options and with some random options bits that are
+generated from the string.
+.P
+Setting --enable-fuzz-support also causes a binary called \fBpcre2fuzzcheck\fP
+to be created. This is normally run under valgrind or used when PCRE2 is
+compiled with address sanitizing enabled. It calls the fuzzing function and
+outputs information about what it is doing. The input strings are specified by
+arguments: if an argument starts with "=" the rest of it is a literal input
+string. Otherwise, it is assumed to be a file name, and the contents of the
+file are the test string.
+.
+.
+.SH "OBSOLETE OPTION"
+.rs
+.sp
+In versions of PCRE2 prior to 10.30, there were two ways of handling
+backtracking in the \fBpcre2_match()\fP function. The default was to use the
+system stack, but if
+.sp
+  --disable-stack-for-recursion
+.sp
+was set, memory on the heap was used. From release 10.30 onwards this has
+changed (the stack is no longer used) and this option now does nothing except
+give a warning.

+.fi
+.
+.SH DESCRIPTION
+.rs
+.sp
+PCRE2 provides a feature called "callout", which is a means of temporarily
+passing control to the caller of PCRE2 in the middle of pattern matching. The
+caller of PCRE2 provides an external function by putting its entry point in
+a match context (see \fBpcre2_set_callout()\fP in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation).
+.P
+When using the \fBpcre2_substitute()\fP function, an additional callout feature
+is available. This does a callout after each change to the subject string and
+is described in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation; the rest of this document is concerned with callouts during
+pattern matching.
+.P
+Within a regular expression, (?C) indicates a point at which the external
+function is to be called. Different callout points can be identified by putting
+a number less than 256 after the letter C. The default value is zero.
+Alternatively, the argument may be a delimited string. The starting delimiter
+must be one of ` ' " ^ % # $ { and the ending delimiter is the same as the
+start, except for {, where the ending delimiter is }. If the ending delimiter
+is needed within the string, it must be doubled. For example, this pattern has
+two callout points:
+.sp
+  (?C1)abc(?C"some ""arbitrary"" text")def
+.sp
+If the PCRE2_AUTO_CALLOUT option bit is set when a pattern is compiled, PCRE2
+automatically inserts callouts, all with number 255, before each item in the
+pattern except for immediately before or after an explicit callout. For
+example, if PCRE2_AUTO_CALLOUT is used with the pattern
+.sp
+  A(?C3)B
+.sp
+it is processed as if it were
+.sp
+  (?C255)A(?C3)B(?C255)
+.sp
+Here is a more complicated example:
+.sp
+  A(\ed{2}|--)
+.sp
+With PCRE2_AUTO_CALLOUT, this pattern is processed as if it were
+.sp
+  (?C255)A(?C255)((?C255)\ed{2}(?C255)|(?C255)-(?C255)-(?C255))(?C255)
+.sp
+Notice that there is a callout before and after each parenthesis and
+alternation bar. If the pattern contains a conditional group whose condition is
+an assertion, an automatic callout is inserted immediately before the
+condition. Such a callout may also be inserted explicitly, for example:
+.sp
+  (?(?C9)(?=a)ab|de)  (?(?C%text%)(?!=d)ab|de)
+.sp
+This applies only to assertion conditions (because they are themselves
+independent groups).
+.P
+Callouts can be useful for tracking the progress of pattern matching. The
+.\" HREF
+\fBpcre2test\fP
+.\"
+program has a pattern qualifier (/auto_callout) that sets automatic callouts.
+When any callouts are present, the output from \fBpcre2test\fP indicates how
+the pattern is being matched. This is useful information when you are trying to
+optimize the performance of a particular pattern.
+.
+.
+.SH "MISSING CALLOUTS"
+.rs
+.sp
+You should be aware that, because of optimizations in the way PCRE2 compiles
+and matches patterns, callouts sometimes do not happen exactly as you might
+expect.
+.
+.
+.SS "Auto-possessification"
+.rs
+.sp
+At compile time, PCRE2 "auto-possessifies" repeated items when it knows that
+what follows cannot be part of the repeat. For example, a+[bc] is compiled as
+if it were a++[bc]. The \fBpcre2test\fP output when this pattern is compiled
+with PCRE2_ANCHORED and PCRE2_AUTO_CALLOUT and then applied to the string
+"aaaa" is:
+.sp
+  --->aaaa
+   +0 ^        a+
+   +2 ^   ^    [bc]
+  No match
+.sp
+This indicates that when matching [bc] fails, there is no backtracking into a+
+(because it is being treated as a++) and therefore the callouts that would be
+taken for the backtracks do not occur. You can disable the auto-possessify
+feature by passing PCRE2_NO_AUTO_POSSESS to \fBpcre2_compile()\fP, or starting
+the pattern with (*NO_AUTO_POSSESS). In this case, the output changes to this:
+.sp
+  --->aaaa
+   +0 ^        a+
+   +2 ^   ^    [bc]
+   +2 ^  ^     [bc]
+   +2 ^ ^      [bc]
+   +2 ^^       [bc]
+  No match
+.sp
+This time, when matching [bc] fails, the matcher backtracks into a+ and tries
+again, repeatedly, until a+ itself fails.
+.
+.
+.SS "Automatic .* anchoring"
+.rs
+.sp
+By default, an optimization is applied when .* is the first significant item in
+a pattern. If PCRE2_DOTALL is set, so that the dot can match any character, the
+pattern is automatically anchored. If PCRE2_DOTALL is not set, a match can
+start only after an internal newline or at the beginning of the subject, and
+\fBpcre2_compile()\fP remembers this. If a pattern has more than one top-level
+branch, automatic anchoring occurs if all branches are anchorable.
+.P
+This optimization is disabled, however, if .* is in an atomic group or if there
+is a backreference to the capture group in which it appears. It is also
+disabled if the pattern contains (*PRUNE) or (*SKIP). However, the presence of
+callouts does not affect it.
+.P
+For example, if the pattern .*\ed is compiled with PCRE2_AUTO_CALLOUT and
+applied to the string "aa", the \fBpcre2test\fP output is:
+.sp
+  --->aa
+   +0 ^      .*
+   +2 ^ ^    \ed
+   +2 ^^     \ed
+   +2 ^      \ed
+  No match
+.sp
+This shows that all match attempts start at the beginning of the subject. In
+other words, the pattern is anchored. You can disable this optimization by
+passing PCRE2_NO_DOTSTAR_ANCHOR to \fBpcre2_compile()\fP, or starting the
+pattern with (*NO_DOTSTAR_ANCHOR). In this case, the output changes to:
+.sp
+  --->aa
+   +0 ^      .*
+   +2 ^ ^    \ed
+   +2 ^^     \ed
+   +2 ^      \ed
+   +0  ^     .*
+   +2  ^^    \ed
+   +2  ^     \ed
+  No match
+.sp
+This shows more match attempts, starting at the second subject character.
+Another optimization, described in the next section, means that there is no
+subsequent attempt to match with an empty subject.
+.
+.
+.SS "Other optimizations"
+.rs
+.sp
+Other optimizations that provide fast "no match" results also affect callouts.
+For example, if the pattern is
+.sp
+  ab(?C4)cd
+.sp
+PCRE2 knows that any matching string must contain the letter "d". If the
+subject string is "abyz", the lack of "d" means that matching doesn't ever
+start, and the callout is never reached. However, with "abyd", though the
+result is still no match, the callout is obeyed.
+.P
+For most patterns PCRE2 also knows the minimum length of a matching string, and
+will immediately give a "no match" return without actually running a match if
+the subject is not long enough, or, for unanchored patterns, if it has been
+scanned far enough.
+.P
+You can disable these optimizations by passing the PCRE2_NO_START_OPTIMIZE
+option to \fBpcre2_compile()\fP, or by starting the pattern with
+(*NO_START_OPT). This slows down the matching process, but does ensure that
+callouts such as the example above are obeyed.
+.
+.
+.\" HTML 
+.SH "THE CALLOUT INTERFACE"
+.rs
+.sp
+During matching, when PCRE2 reaches a callout point, if an external function is
+provided in the match context, it is called. This applies to both normal,
+DFA, and JIT matching. The first argument to the callout function is a pointer
+to a \fBpcre2_callout\fP block. The second argument is the void * callout data
+that was supplied when the callout was set up by calling
+\fBpcre2_set_callout()\fP (see the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation). The callout block structure contains the following fields, not
+necessarily in this order:
+.sp
+  uint32_t      \fIversion\fP;
+  uint32_t      \fIcallout_number\fP;
+  uint32_t      \fIcapture_top\fP;
+  uint32_t      \fIcapture_last\fP;
+  uint32_t      \fIcallout_flags\fP;
+  PCRE2_SIZE   *\fIoffset_vector\fP;
+  PCRE2_SPTR    \fImark\fP;
+  PCRE2_SPTR    \fIsubject\fP;
+  PCRE2_SIZE    \fIsubject_length\fP;
+  PCRE2_SIZE    \fIstart_match\fP;
+  PCRE2_SIZE    \fIcurrent_position\fP;
+  PCRE2_SIZE    \fIpattern_position\fP;
+  PCRE2_SIZE    \fInext_item_length\fP;
+  PCRE2_SIZE    \fIcallout_string_offset\fP;
+  PCRE2_SIZE    \fIcallout_string_length\fP;
+  PCRE2_SPTR    \fIcallout_string\fP;
+.sp
+The \fIversion\fP field contains the version number of the block format. The
+current version is 2; the three callout string fields were added for version 1,
+and the \fIcallout_flags\fP field for version 2. If you are writing an
+application that might use an earlier release of PCRE2, you should check the
+version number before accessing any of these fields. The version number will
+increase in future if more fields are added, but the intention is never to
+remove any of the existing fields.
+.
+.
+.SS "Fields for numerical callouts"
+.rs
+.sp
+For a numerical callout, \fIcallout_string\fP is NULL, and \fIcallout_number\fP
+contains the number of the callout, in the range 0-255. This is the number
+that follows (?C for callouts that part of the pattern; it is 255 for
+automatically generated callouts.
+.
+.
+.SS "Fields for string callouts"
+.rs
+.sp
+For callouts with string arguments, \fIcallout_number\fP is always zero, and
+\fIcallout_string\fP points to the string that is contained within the compiled
+pattern. Its length is given by \fIcallout_string_length\fP. Duplicated ending
+delimiters that were present in the original pattern string have been turned
+into single characters, but there is no other processing of the callout string
+argument. An additional code unit containing binary zero is present after the
+string, but is not included in the length. The delimiter that was used to start
+the string is also stored within the pattern, immediately before the string
+itself. You can access this delimiter as \fIcallout_string\fP[-1] if you need
+it.
+.P
+The \fIcallout_string_offset\fP field is the code unit offset to the start of
+the callout argument string within the original pattern string. This is
+provided for the benefit of applications such as script languages that might
+need to report errors in the callout string within the pattern.
+.
+.
+.SS "Fields for all callouts"
+.rs
+.sp
+The remaining fields in the callout block are the same for both kinds of
+callout.
+.P
+The \fIoffset_vector\fP field is a pointer to a vector of capturing offsets
+(the "ovector"). You may read the elements in this vector, but you must not
+change any of them.
+.P
+For calls to \fBpcre2_match()\fP, the \fIoffset_vector\fP field is not (since
+release 10.30) a pointer to the actual ovector that was passed to the matching
+function in the match data block. Instead it points to an internal ovector of a
+size large enough to hold all possible captured substrings in the pattern. Note
+that whenever a recursion or subroutine call within a pattern completes, the
+capturing state is reset to what it was before.
+.P
+The \fIcapture_last\fP field contains the number of the most recently captured
+substring, and the \fIcapture_top\fP field contains one more than the number of
+the highest numbered captured substring so far. If no substrings have yet been
+captured, the value of \fIcapture_last\fP is 0 and the value of
+\fIcapture_top\fP is 1. The values of these fields do not always differ by one;
+for example, when the callout in the pattern ((a)(b))(?C2) is taken,
+\fIcapture_last\fP is 1 but \fIcapture_top\fP is 4.
+.P
+The contents of ovector[2] to ovector[*2-1] can be inspected in
+order to extract substrings that have been matched so far, in the same way as
+extracting substrings after a match has completed. The values in ovector[0] and
+ovector[1] are always PCRE2_UNSET because the match is by definition not
+complete. Substrings that have not been captured but whose numbers are less
+than \fIcapture_top\fP also have both of their ovector slots set to
+PCRE2_UNSET.
+.P
+For DFA matching, the \fIoffset_vector\fP field points to the ovector that was
+passed to the matching function in the match data block for callouts at the top
+level, but to an internal ovector during the processing of pattern recursions,
+lookarounds, and atomic groups. However, these ovectors hold no useful
+information because \fBpcre2_dfa_match()\fP does not support substring
+capturing. The value of \fIcapture_top\fP is always 1 and the value of
+\fIcapture_last\fP is always 0 for DFA matching.
+.P
+The \fIsubject\fP and \fIsubject_length\fP fields contain copies of the values
+that were passed to the matching function.
+.P
+The \fIstart_match\fP field normally contains the offset within the subject at
+which the current match attempt started. However, if the escape sequence \eK
+has been encountered, this value is changed to reflect the modified starting
+point. If the pattern is not anchored, the callout function may be called
+several times from the same point in the pattern for different starting points
+in the subject.
+.P
+The \fIcurrent_position\fP field contains the offset within the subject of the
+current match pointer.
+.P
+The \fIpattern_position\fP field contains the offset in the pattern string to
+the next item to be matched.
+.P
+The \fInext_item_length\fP field contains the length of the next item to be
+processed in the pattern string. When the callout is at the end of the pattern,
+the length is zero. When the callout precedes an opening parenthesis, the
+length includes meta characters that follow the parenthesis. For example, in a
+callout before an assertion such as (?=ab) the length is 3. For an alternation
+bar or a closing parenthesis, the length is one, unless a closing parenthesis
+is followed by a quantifier, in which case its length is included. (This
+changed in release 10.23. In earlier releases, before an opening parenthesis
+the length was that of the entire group, and before an alternation bar or a
+closing parenthesis the length was zero.)
+.P
+The \fIpattern_position\fP and \fInext_item_length\fP fields are intended to
+help in distinguishing between different automatic callouts, which all have the
+same callout number. However, they are set for all callouts, and are used by
+\fBpcre2test\fP to show the next item to be matched when displaying callout
+information.
+.P
+In callouts from \fBpcre2_match()\fP the \fImark\fP field contains a pointer to
+the zero-terminated name of the most recently passed (*MARK), (*PRUNE), or
+(*THEN) item in the match, or NULL if no such items have been passed. Instances
+of (*PRUNE) or (*THEN) without a name do not obliterate a previous (*MARK). In
+callouts from the DFA matching function this field always contains NULL.
+.P
+The \fIcallout_flags\fP field is always zero in callouts from
+\fBpcre2_dfa_match()\fP or when JIT is being used. When \fBpcre2_match()\fP
+without JIT is used, the following bits may be set:
+.sp
+  PCRE2_CALLOUT_STARTMATCH
+.sp
+This is set for the first callout after the start of matching for each new
+starting position in the subject.
+.sp
+  PCRE2_CALLOUT_BACKTRACK
+.sp
+This is set if there has been a matching backtrack since the previous callout,
+or since the start of matching if this is the first callout from a
+\fBpcre2_match()\fP run.
+.P
+Both bits are set when a backtrack has caused a "bumpalong" to a new starting
+position in the subject. Output from \fBpcre2test\fP does not indicate the
+presence of these bits unless the \fBcallout_extra\fP modifier is set.
+.P
+The information in the \fBcallout_flags\fP field is provided so that
+applications can track and tell their users how matching with backtracking is
+done. This can be useful when trying to optimize patterns, or just to
+understand how PCRE2 works. There is no support in \fBpcre2_dfa_match()\fP
+because there is no backtracking in DFA matching, and there is no support in
+JIT because JIT is all about maximimizing matching performance. In both these
+cases the \fBcallout_flags\fP field is always zero.
+.
+.
+.SH "RETURN VALUES FROM CALLOUTS"
+.rs
+.sp
+The external callout function returns an integer to PCRE2. If the value is
+zero, matching proceeds as normal. If the value is greater than zero, matching
+fails at the current point, but the testing of other matching possibilities
+goes ahead, just as if a lookahead assertion had failed. If the value is less
+than zero, the match is abandoned, and the matching function returns the
+negative value.
+.P
+Negative values should normally be chosen from the set of PCRE2_ERROR_xxx
+values. In particular, PCRE2_ERROR_NOMATCH forces a standard "no match"
+failure. The error number PCRE2_ERROR_CALLOUT is reserved for use by callout
+functions; it will never be used by PCRE2 itself.
+.
+.
+.SH "CALLOUT ENUMERATION"
+.rs
+.sp
+.nf
+.B int pcre2_callout_enumerate(const pcre2_code *\fIcode\fP,
+.B "  int (*\fIcallback\fP)(pcre2_callout_enumerate_block *, void *),"
+.B "  void *\fIuser_data\fP);"
+.fi
+.sp
+A script language that supports the use of string arguments in callouts might
+like to scan all the callouts in a pattern before running the match. This can
+be done by calling \fBpcre2_callout_enumerate()\fP. The first argument is a
+pointer to a compiled pattern, the second points to a callback function, and
+the third is arbitrary user data. The callback function is called for every
+callout in the pattern in the order in which they appear. Its first argument is
+a pointer to a callout enumeration block, and its second argument is the
+\fIuser_data\fP value that was passed to \fBpcre2_callout_enumerate()\fP. The
+data block contains the following fields:
+.sp
+  \fIversion\fP                Block version number
+  \fIpattern_position\fP       Offset to next item in pattern
+  \fInext_item_length\fP       Length of next item in pattern
+  \fIcallout_number\fP         Number for numbered callouts
+  \fIcallout_string_offset\fP  Offset to string within pattern
+  \fIcallout_string_length\fP  Length of callout string
+  \fIcallout_string\fP         Points to callout string or is NULL
+.sp
+The version number is currently 0. It will increase if new fields are ever
+added to the block. The remaining fields are the same as their namesakes in the
+\fBpcre2_callout\fP block that is used for callouts during matching, as
+described
+.\" HTML 
+.\" 
+above.
+.\"
+.P
+Note that the value of \fIpattern_position\fP is unique for each callout.
+However, if a callout occurs inside a group that is quantified with a non-zero
+minimum or a fixed maximum, the group is replicated inside the compiled
+pattern. For example, a pattern such as /(a){2}/ is compiled as if it were
+/(a)(a)/. This means that the callout will be enumerated more than once, but
+with the same value for \fIpattern_position\fP in each case.
+.P
+The callback function should normally return zero. If it returns a non-zero
+value, scanning the pattern stops, and that value is returned from
+\fBpcre2_callout_enumerate()\fP.

+.TH PCRE2COMPAT 3 "30 November 2023" "PCRE2 10.43"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "DIFFERENCES BETWEEN PCRE2 AND PERL"
+.rs
+.sp
+This document describes some of the known differences in the ways that PCRE2
+and Perl handle regular expressions. The differences described here are with
+respect to Perl version 5.38.0, but as both Perl and PCRE2 are continually
+changing, the information may at times be out of date.
+.P
+1. When PCRE2_DOTALL (equivalent to Perl's /s qualifier) is not set, the
+behaviour of the '.' metacharacter differs from Perl. In PCRE2, '.' matches the
+next character unless it is the start of a newline sequence. This means that,
+if the newline setting is CR, CRLF, or NUL, '.' will match the code point LF
+(0x0A) in ASCII/Unicode environments, and NL (either 0x15 or 0x25) when using
+EBCDIC. In Perl, '.' appears never to match LF, even when 0x0A is not a newline
+indicator.
+.P
+2. PCRE2 has only a subset of Perl's Unicode support. Details of what it does
+have are given in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+page.
+.P
+3. Like Perl, PCRE2 allows repeat quantifiers on parenthesized assertions, but
+they do not mean what you might think. For example, (?!a){3} does not assert
+that the next three characters are not "a". It just asserts that the next
+character is not "a" three times (in principle; PCRE2 optimizes this to run the
+assertion just once). Perl allows some repeat quantifiers on other assertions,
+for example, \eb* , but these do not seem to have any use. PCRE2 does not allow
+any kind of quantifier on non-lookaround assertions.
+.P
+4. If a braced quantifier such as {1,2} appears where there is nothing to
+repeat (for example, at the start of a branch), PCRE2 raises an error whereas
+Perl treats the quantifier characters as literal.
+.P
+5. Capture groups that occur inside negative lookaround assertions are counted,
+but their entries in the offsets vector are set only when a negative assertion
+is a condition that has a matching branch (that is, the condition is false).
+Perl may set such capture groups in other circumstances.
+.P
+6. The following Perl escape sequences are not supported: \eF, \el, \eL, \eu,
+\eU, and \eN when followed by a character name. \eN on its own, matching a
+non-newline character, and \eN{U+dd..}, matching a Unicode code point, are
+supported. The escapes that modify the case of following letters are
+implemented by Perl's general string-handling and are not part of its pattern
+matching engine. If any of these are encountered by PCRE2, an error is
+generated by default. However, if either of the PCRE2_ALT_BSUX or
+PCRE2_EXTRA_ALT_BSUX options is set, \eU and \eu are interpreted as ECMAScript
+interprets them.
+.P
+7. The Perl escape sequences \ep, \eP, and \eX are supported only if PCRE2 is
+built with Unicode support (the default). The properties that can be tested
+with \ep and \eP are limited to the general category properties such as Lu and
+Nd, the derived properties Any and LC (synonym L&), script names such as Greek
+or Han, Bidi_Class, Bidi_Control, and a few binary properties. Both PCRE2 and
+Perl support the Cs (surrogate) property, but in PCRE2 its use is limited. See
+the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation for details. The long synonyms for property names that Perl
+supports (such as \ep{Letter}) are not supported by PCRE2, nor is it permitted
+to prefix any of these properties with "Is".
+.P
+8. PCRE2 supports the \eQ...\eE escape for quoting substrings. Characters
+in between are treated as literals. However, this is slightly different from
+Perl in that $ and @ are also handled as literals inside the quotes. In Perl,
+they cause variable interpolation (PCRE2 does not have variables). Also, Perl
+does "double-quotish backslash interpolation" on any backslashes between \eQ
+and \eE which, its documentation says, "may lead to confusing results". PCRE2
+treats a backslash between \eQ and \eE just like any other character. Note the
+following examples:
+.sp
+    Pattern            PCRE2 matches     Perl matches
+.sp
+.\" JOIN
+    \eQabc$xyz\eE        abc$xyz           abc followed by the
+                                           contents of $xyz
+    \eQabc\e$xyz\eE       abc\e$xyz          abc\e$xyz
+    \eQabc\eE\e$\eQxyz\eE   abc$xyz           abc$xyz
+    \eQA\eB\eE            A\eB               A\eB
+    \eQ\e\eE              \e                 \e\eE
+.sp
+The \eQ...\eE sequence is recognized both inside and outside character classes
+by both PCRE2 and Perl.
+.P
+9. Fairly obviously, PCRE2 does not support the (?{code}) and (??{code})
+constructions. However, PCRE2 does have a "callout" feature, which allows an
+external function to be called during pattern matching. See the
+.\" HREF
+\fBpcre2callout\fP
+.\"
+documentation for details.
+.P
+10. Subroutine calls (whether recursive or not) were treated as atomic groups
+up to PCRE2 release 10.23, but from release 10.30 this changed, and
+backtracking into subroutine calls is now supported, as in Perl.
+.P
+11. In PCRE2, if any of the backtracking control verbs are used in a group that
+is called as a subroutine (whether or not recursively), their effect is
+confined to that group; it does not extend to the surrounding pattern. This is
+not always the case in Perl. In particular, if (*THEN) is present in a group
+that is called as a subroutine, its action is limited to that group, even if
+the group does not contain any | characters. Note that such groups are
+processed as anchored at the point where they are tested.
+.P
+12. If a pattern contains more than one backtracking control verb, the first
+one that is backtracked onto acts. For example, in the pattern
+A(*COMMIT)B(*PRUNE)C a failure in B triggers (*COMMIT), but a failure in C
+triggers (*PRUNE). Perl's behaviour is more complex; in many cases it is the
+same as PCRE2, but there are cases where it differs.
+.P
+13. There are some differences that are concerned with the settings of captured
+strings when part of a pattern is repeated. For example, matching "aba" against
+the pattern /^(a(b)?)+$/ in Perl leaves $2 unset, but in PCRE2 it is set to
+"b".
+.P
+14. PCRE2's handling of duplicate capture group numbers and names is not as
+general as Perl's. This is a consequence of the fact the PCRE2 works internally
+just with numbers, using an external table to translate between numbers and
+names. In particular, a pattern such as (?|(?A)|(?B)), where the two
+capture groups have the same number but different names, is not supported, and
+causes an error at compile time. If it were allowed, it would not be possible
+to distinguish which group matched, because both names map to capture group
+number 1. To avoid this confusing situation, an error is given at compile time.
+.P
+15. Perl used to recognize comments in some places that PCRE2 does not, for
+example, between the ( and ? at the start of a group. If the /x modifier is
+set, Perl allowed white space between ( and ? though the latest Perls give an
+error (for a while it was just deprecated). There may still be some cases where
+Perl behaves differently.
+.P
+16. Perl, when in warning mode, gives warnings for character classes such as
+[A-\ed] or [a-[:digit:]]. It then treats the hyphens as literals. PCRE2 has no
+warning features, so it gives an error in these cases because they are almost
+certainly user mistakes.
+.P
+17. In PCRE2, the upper/lower case character properties Lu and Ll are not
+affected when case-independent matching is specified. For example, \ep{Lu}
+always matches an upper case letter. I think Perl has changed in this respect;
+in the release at the time of writing (5.38), \ep{Lu} and \ep{Ll} match all
+letters, regardless of case, when case independence is specified.
+.P
+18. From release 5.32.0, Perl locks out the use of \eK in lookaround
+assertions. From release 10.38 PCRE2 does the same by default. However, there
+is an option for re-enabling the previous behaviour. When this option is set,
+\eK is acted on when it occurs in positive assertions, but is ignored in
+negative assertions.
+.P
+19. PCRE2 provides some extensions to the Perl regular expression facilities.
+Perl 5.10 included new features that were not in earlier versions of Perl, some
+of which (such as named parentheses) were in PCRE2 for some time before. This
+list is with respect to Perl 5.38:
+.sp
+(a) If PCRE2_DOLLAR_ENDONLY is set and PCRE2_MULTILINE is not set, the $
+meta-character matches only at the very end of the string.
+.sp
+(b) A backslash followed by a letter with no special meaning is faulted. (Perl
+can be made to issue a warning.)
+.sp
+(c) If PCRE2_UNGREEDY is set, the greediness of the repetition quantifiers is
+inverted, that is, by default they are not greedy, but if followed by a
+question mark they are.
+.sp
+(d) PCRE2_ANCHORED can be used at matching time to force a pattern to be tried
+only at the first matching position in the subject string.
+.sp
+(e) The PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY and PCRE2_NOTEMPTY_ATSTART
+options have no Perl equivalents.
+.sp
+(f) The \eR escape sequence can be restricted to match only CR, LF, or CRLF
+by the PCRE2_BSR_ANYCRLF option.
+.sp
+(g) The callout facility is PCRE2-specific. Perl supports codeblocks and
+variable interpolation, but not general hooks on every match.
+.sp
+(h) The partial matching facility is PCRE2-specific.
+.sp
+(i) The alternative matching function (\fBpcre2_dfa_match()\fP matches in a
+different way and is not Perl-compatible.
+.sp
+(j) PCRE2 recognizes some special sequences such as (*CR) or (*NO_JIT) at
+the start of a pattern. These set overall options that cannot be changed within
+the pattern.
+.sp
+(k) PCRE2 supports non-atomic positive lookaround assertions. This is an
+extension to the lookaround facilities. The default, Perl-compatible
+lookarounds are atomic.
+.sp
+(l) There are three syntactical items in patterns that can refer to a capturing
+group by number: back references such as \eg{2}, subroutine calls such as (?3),
+and condition references such as (?(4)...). PCRE2 supports relative group
+numbers such as +2 and -4 in all three cases. Perl supports both plus and minus
+for subroutine calls, but only minus for back references, and no relative
+numbering at all for conditions.
+.P
+20. Perl has different limits than PCRE2. See the
+.\" HREF
+\fBpcre2limit\fP
+.\"
+documentation for details. Perl went with 5.10 from recursion to iteration
+keeping the intermediate matches on the heap, which is ~10% slower but does not
+fall into any stack-overflow limit. PCRE2 made a similar change at release
+10.30, and also has many build-time and run-time customizable limits.
+.P
+21. Unlike Perl, PCRE2 doesn't have character set modifiers and specially no way
+to set characters by context just like Perl's "/d". A regular expression using
+PCRE2_UTF and PCRE2_UCP will use similar rules to Perl's "/u"; something closer
+to "/a" could be selected by adding other PCRE2_EXTRA_ASCII* options on top.
+.P
+22. Some recursive patterns that Perl diagnoses as infinite recursions can be
+handled by PCRE2, either by the interpreter or the JIT. An example is
+/(?:|(?0)abcd)(?(R)|\ez)/, which matches a sequence of any number of repeated
+"abcd" substrings at the end of the subject.

+.TH PCRE2CONVERT 3 "28 June 2018" "PCRE2 10.32"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "EXPERIMENTAL PATTERN CONVERSION FUNCTIONS"
+.rs
+.sp
+This document describes a set of functions that can be used to convert
+"foreign" patterns into PCRE2 regular expressions. This facility is currently
+experimental, and may be changed in future releases. Two kinds of pattern,
+globs and POSIX patterns, are supported.
+.
+.
+.SH "THE CONVERT CONTEXT"
+.rs
+.sp
+.nf
+.B pcre2_convert_context *pcre2_convert_context_create(
+.B "  pcre2_general_context *\fIgcontext\fP);"
+.sp
+.B pcre2_convert_context *pcre2_convert_context_copy(

+.sp
+.B int pcre2_set_glob_separator(pcre2_convert_context *\fIcvcontext\fP,
+.B "  uint32_t \fIseparator_char\fP);"
+.fi
+.sp
+A convert context is used to hold parameters that affect the way that pattern
+conversion works. Like all PCRE2 contexts, you need to use a context only if
+you want to override the defaults. There are the usual create, copy, and free
+functions. If custom memory management functions are set in a general context
+that is passed to \fBpcre2_convert_context_create()\fP, they are used for all
+memory management within the conversion functions.
+.P
+There are only two parameters in the convert context at present. Both apply
+only to glob conversions. The escape character defaults to grave accent under
+Windows, otherwise backslash. It can be set to zero, meaning no escape
+character, or to any punctuation character with a code point less than 256.
+The separator character defaults to backslash under Windows, otherwise forward
+slash. It can be set to forward slash, backslash, or dot.
+.P
+The two setting functions return zero on success, or PCRE2_ERROR_BADDATA if
+their second argument is invalid.
+.
+.
+.SH "THE CONVERSION FUNCTION"
+.rs
+.sp
+.nf
+.B int pcre2_pattern_convert(PCRE2_SPTR \fIpattern\fP, PCRE2_SIZE \fIlength\fP,
+.B "  uint32_t \fIoptions\fP, PCRE2_UCHAR **\fIbuffer\fP,"
+.B "  PCRE2_SIZE *\fIblength\fP, pcre2_convert_context *\fIcvcontext\fP);"
+.sp
+.B void pcre2_converted_pattern_free(PCRE2_UCHAR *\fIconverted_pattern\fP);
+.fi
+.sp
+The first two arguments of \fBpcre2_pattern_convert()\fP define the foreign
+pattern that is to be converted. The length may be given as
+PCRE2_ZERO_TERMINATED. The \fBoptions\fP argument defines how the pattern is to
+be processed. If the input is UTF, the PCRE2_CONVERT_UTF option should be set.
+PCRE2_CONVERT_NO_UTF_CHECK may also be set if you are sure the input is valid.
+One or more of the glob options, or one of the following POSIX options must be
+set to define the type of conversion that is required:
+.sp
+  PCRE2_CONVERT_GLOB
+  PCRE2_CONVERT_GLOB_NO_WILD_SEPARATOR
+  PCRE2_CONVERT_GLOB_NO_STARSTAR
+  PCRE2_CONVERT_POSIX_BASIC
+  PCRE2_CONVERT_POSIX_EXTENDED
+.sp
+Details of the conversions are given below. The \fBbuffer\fP and \fBblength\fP
+arguments define how the output is handled:
+.P
+If \fBbuffer\fP is NULL, the function just returns the length of the converted
+pattern via \fBblength\fP. This is one less than the length of buffer needed,
+because a terminating zero is always added to the output.
+.P
+If \fBbuffer\fP points to a NULL pointer, an output buffer is obtained using
+the allocator in the context or \fBmalloc()\fP if no context is supplied. A
+pointer to this buffer is placed in the variable to which \fBbuffer\fP points.
+When no longer needed the output buffer must be freed by calling
+\fBpcre2_converted_pattern_free()\fP. If this function is called with a NULL
+argument, it returns immediately without doing anything.
+.P
+If \fBbuffer\fP points to a non-NULL pointer, \fBblength\fP must be set to the
+actual length of the buffer provided (in code units).
+.P
+In all cases, after successful conversion, the variable pointed to by
+\fBblength\fP is updated to the length actually used (in code units), excluding
+the terminating zero that is always added.
+.P
+If an error occurs, the length (via \fBblength\fP) is set to the offset
+within the input pattern where the error was detected. Only gross syntax errors
+are caught; there are plenty of errors that will get passed on for
+\fBpcre2_compile()\fP to discover.
+.P
+The return from \fBpcre2_pattern_convert()\fP is zero on success or a non-zero
+PCRE2 error code. Note that PCRE2 error codes may be positive or negative:
+\fBpcre2_compile()\fP uses mostly positive codes and \fBpcre2_match()\fP
+negative ones; \fBpcre2_convert()\fP uses existing codes of both kinds. A
+textual error message can be obtained by calling
+\fBpcre2_get_error_message()\fP.
+.
+.
+.SH "CONVERTING GLOBS"
+.rs
+.sp
+Globs are used to match file names, and consequently have the concept of a
+"path separator", which defaults to backslash under Windows and forward slash
+otherwise. If PCRE2_CONVERT_GLOB is set, the wildcards * and ? are not
+permitted to match separator characters, but the double-star (**) feature
+(which does match separators) is supported.
+.P
+PCRE2_CONVERT_GLOB_NO_WILD_SEPARATOR matches globs with wildcards allowed to
+match separator characters. PCRE2_CONVERT_GLOB_NO_STARSTAR matches globs with
+the double-star feature disabled. These options may be given together.
+.
+.
+.SH "CONVERTING POSIX PATTERNS"
+.rs
+.sp
+POSIX defines two kinds of regular expression pattern: basic and extended.
+These can be processed by setting PCRE2_CONVERT_POSIX_BASIC or
+PCRE2_CONVERT_POSIX_EXTENDED, respectively.
+.P
+In POSIX patterns, backslash is not special in a character class. Unmatched
+closing parentheses are treated as literals.
+.P
+In basic patterns, ? + | {} and () must be escaped to be recognized
+as metacharacters outside a character class. If the first character in the
+pattern is * it is treated as a literal. ^ is a metacharacter only at the start
+of a branch.
+.P
+In extended patterns, a backslash not in a character class always
+makes the next character literal, whatever it is. There are no backreferences.
+.P
+Note: POSIX mandates that the longest possible match at the first matching
+position must be found. This is not what \fBpcre2_match()\fP does; it yields
+the first match that is found. An application can use \fBpcre2_dfa_match()\fP
+to find the longest match, but that does not support backreferences (but then
+neither do POSIX extended patterns).

+*           PCRE2 DEMONSTRATION PROGRAM          *
+*************************************************/
+
+/* This is a demonstration program to illustrate a straightforward way of
+using the PCRE2 regular expression library from a C program. See the
+pcre2sample documentation for a short discussion ("man pcre2sample" if you have
+the PCRE2 man pages installed). PCRE2 is a revised API for the library, and is
+incompatible with the original PCRE API.
+
+There are actually three libraries, each supporting a different code unit
+width. This demonstration program uses the 8-bit library. The default is to
+process each code unit as a separate character, but if the pattern begins with
+"(*UTF)", both it and the subject are treated as UTF-8 strings, where
+characters may occupy multiple code units.
+
+In Unix-like environments, if PCRE2 is installed in your standard system
+libraries, you should be able to compile this program using this command:
+
+cc -Wall pcre2demo.c -lpcre2-8 -o pcre2demo
+
+If PCRE2 is not installed in a standard place, it is likely to be installed
+with support for the pkg-config mechanism. If you have pkg-config, you can
+compile this program using this command:
+
+cc -Wall pcre2demo.c `pkg-config --cflags --libs libpcre2-8` -o pcre2demo
+
+If you do not have pkg-config, you may have to use something like this:
+
+cc -Wall pcre2demo.c -I/usr/local/include -L/usr/local/lib \e
+  -R/usr/local/lib -lpcre2-8 -o pcre2demo
+
+Replace "/usr/local/include" and "/usr/local/lib" with wherever the include and
+library files for PCRE2 are installed on your system. Only some operating
+systems (Solaris is one) use the -R option.
+
+Building under Windows:
+
+If you want to statically link this program against a non-dll .a file, you must
+define PCRE2_STATIC before including pcre2.h, so in this environment, uncomment
+the following line. */
+
+/* #define PCRE2_STATIC */
+
+/* The PCRE2_CODE_UNIT_WIDTH macro must be defined before including pcre2.h.
+For a program that uses only one code unit width, setting it to 8, 16, or 32
+makes it possible to use generic function names such as pcre2_compile(). Note
+that just changing 8 to 16 (for example) is not sufficient to convert this
+program to process 16-bit characters. Even in a fully 16-bit environment, where
+string-handling functions such as strcmp() and printf() work with 16-bit
+characters, the code for handling the table of named substrings will still need
+to be modified. */

+* If the "-g" option was given on the command line, we want to continue  *

+* might think because of the possibility of matching an empty string.    *
+* What happens is as follows:                                            *
+*                                                                        *

+* the next match at the end of the previous one.                         *
+*                                                                        *
+* If the previous match WAS for an empty string, we can't do that, as it *
+* would lead to an infinite loop. Instead, a call of pcre2_match() is    *
+* made with the PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set. The *
+* first of these tells PCRE2 that an empty string at the start of the    *
+* subject is not a valid match; other possibilities must be tried. The   *
+* second flag restricts PCRE2 to one match attempt at the initial string *
+* position. If this match succeeds, an alternative to the empty string   *
+* match has been found, and we can print it and proceed round the loop,  *
+* advancing by the length of whatever was found. If this match does not  *
+* succeed, we still stay in the loop, advancing by just one character.   *
+* In UTF-8 mode, which can be set by (*UTF) in the pattern, this may be  *
+* more than one byte.                                                    *

+* However, there is a complication concerned with newlines. When the     *
+* newline convention is such that CRLF is a valid newline, we must       *
+* advance by two characters rather than one. The newline convention can  *
+* be set in the regex by (*CR), etc.; if not, we must find the default.  *

+.SH NAME
+pcre2grep - a grep with Perl-compatible regular expressions.
+.SH SYNOPSIS
+.B pcre2grep [options] [long options] [pattern] [path1 path2 ...]
+.
+.SH DESCRIPTION
+.rs
+.sp
+\fBpcre2grep\fP searches files for character patterns, in the same way as other
+grep commands do, but it uses the PCRE2 regular expression library to support
+patterns that are compatible with the regular expressions of Perl 5. See
+.\" HREF
+\fBpcre2syntax\fP(3)
+.\"
+for a quick-reference summary of pattern syntax, or
+.\" HREF
+\fBpcre2pattern\fP(3)
+.\"
+for a full description of the syntax and semantics of the regular expressions
+that PCRE2 supports.
+.P
+Patterns, whether supplied on the command line or in a separate file, are given
+without delimiters. For example:
+.sp
+  pcre2grep Thursday /etc/motd
+.sp
+If you attempt to use delimiters (for example, by surrounding a pattern with
+slashes, as is common in Perl scripts), they are interpreted as part of the
+pattern. Quotes can of course be used to delimit patterns on the command line
+because they are interpreted by the shell, and indeed quotes are required if a
+pattern contains white space or shell metacharacters.
+.P
+The first argument that follows any option settings is treated as the single
+pattern to be matched when neither \fB-e\fP nor \fB-f\fP is present.
+Conversely, when one or both of these options are used to specify patterns, all
+arguments are treated as path names. At least one of \fB-e\fP, \fB-f\fP, or an
+argument pattern must be provided.
+.P
+If no files are specified, \fBpcre2grep\fP reads the standard input. The
+standard input can also be referenced by a name consisting of a single hyphen.
+For example:
+.sp
+  pcre2grep some-pattern file1 - file3
+.sp
+By default, input files are searched line by line, so pattern assertions about
+the beginning and end of a subject string (^, $, \eA, \eZ, and \ez) match at
+the beginning and end of each line. When a line matches a pattern, it is copied
+to the standard output, and if there is more than one file, the file name is
+output at the start of each line, followed by a colon. However, there are
+options that can change how \fBpcre2grep\fP behaves. For example, the \fB-M\fP
+option makes it possible to search for strings that span line boundaries. What
+defines a line boundary is controlled by the \fB-N\fP (\fB--newline\fP) option.
+The \fB-h\fP and \fB-H\fP options control whether or not file names are shown,
+and the \fB-Z\fP option changes the file name terminator to a zero byte.
+.P
+The amount of memory used for buffering files that are being scanned is
+controlled by parameters that can be set by the \fB--buffer-size\fP and
+\fB--max-buffer-size\fP options. The first of these sets the size of buffer
+that is obtained at the start of processing. If an input file contains very
+long lines, a larger buffer may be needed; this is handled by automatically
+extending the buffer, up to the limit specified by \fB--max-buffer-size\fP. The
+default values for these parameters can be set when \fBpcre2grep\fP is
+built; if nothing is specified, the defaults are set to 20KiB and 1MiB
+respectively. An error occurs if a line is too long and the buffer can no
+longer be expanded.
+.P
+The block of memory that is actually used is three times the "buffer size", to
+allow for buffering "before" and "after" lines. If the buffer size is too
+small, fewer than requested "before" and "after" lines may be output.
+.P
+When matching with a multiline pattern, the size of the buffer must be at least
+half of the maximum match expected or the pattern might fail to match.
+.P
+Patterns can be no longer than 8KiB or BUFSIZ bytes, whichever is the greater.
+BUFSIZ is defined in \fB\fP. When there is more than one pattern
+(specified by the use of \fB-e\fP and/or \fB-f\fP), each pattern is applied to
+each line in the order in which they are defined, except that all the \fB-e\fP
+patterns are tried before the \fB-f\fP patterns.
+.P
+By default, as soon as one pattern matches a line, no further patterns are
+considered. However, if \fB--colour\fP (or \fB--color\fP) is used to colour the
+matching substrings, or if \fB--only-matching\fP, \fB--file-offsets\fP,
+\fB--line-offsets\fP, or \fB--output\fP is used to output only the part of the
+line that matched (either shown literally, or as an offset), the behaviour is
+different. In this situation, all the patterns are applied to the line. If
+there is more than one match, the one that begins nearest to the start of the
+subject is processed; if there is more than one match at that position, the one
+with the longest matching substring is processed; if the matching substrings
+are equal, the first match found is processed.
+.P
+Scanning with all the patterns resumes immediately following the match, so that
+later matches on the same line can be found. Note, however, that an overlapping
+match that starts in the middle of another match will not be processed.
+.P
+The above behaviour was changed at release 10.41 to be more compatible with GNU
+grep. In earlier releases, \fBpcre2grep\fP did not recognize matches from
+later patterns that were earlier in the subject.
+.P
+Patterns that can match an empty string are accepted, but empty string
+matches are never recognized. An example is the pattern "(super)?(man)?", in
+which all components are optional. This pattern finds all occurrences of both
+"super" and "man"; the output differs from matching with "super|man" when only
+the matching substrings are being shown.
+.P
+If the \fBLC_ALL\fP or \fBLC_CTYPE\fP environment variable is set,
+\fBpcre2grep\fP uses the value to set a locale when calling the PCRE2 library.
+The \fB--locale\fP option can be used to override this.
+.
+.
+.SH "SUPPORT FOR COMPRESSED FILES"
+.rs
+.sp
+Compile-time options for \fBpcre2grep\fP can set it up to use \fBlibz\fP or
+\fBlibbz2\fP for reading compressed files whose names end in \fB.gz\fP or
+\fB.bz2\fP, respectively. You can find out whether your \fBpcre2grep\fP binary
+has support for one or both of these file types by running it with the
+\fB--help\fP option. If the appropriate support is not present, all files are
+treated as plain text. The standard input is always so treated. If a file with
+a \fB.gz\fP or \fB.bz2\fP extension is not in fact compressed, it is read as a
+plain text file. When input is from a compressed .gz or .bz2 file, the
+\fB--line-buffered\fP option is ignored.
+.
+.
+.SH "BINARY FILES"
+.rs
+.sp
+By default, a file that contains a binary zero byte within the first 1024 bytes
+is identified as a binary file, and is processed specially. However, if the
+newline type is specified as NUL, that is, the line terminator is a binary
+zero, the test for a binary file is not applied. See the \fB--binary-files\fP
+option for a means of changing the way binary files are handled.
+.
+.
+.SH "BINARY ZEROS IN PATTERNS"
+.rs
+.sp
+Patterns passed from the command line are strings that are terminated by a
+binary zero, so cannot contain internal zeros. However, patterns that are read
+from a file via the \fB-f\fP option may contain binary zeros.
+.
+.
+.SH OPTIONS
+.rs
+.sp
+The order in which some of the options appear can affect the output. For
+example, both the \fB-H\fP and \fB-l\fP options affect the printing of file
+names. Whichever comes later in the command line will be the one that takes
+effect. Similarly, except where noted below, if an option is given twice, the
+later setting is used. Numerical values for options may be followed by K or M,
+to signify multiplication by 1024 or 1024*1024 respectively.
+.TP 10
+\fB--\fP
+This terminates the list of options. It is useful if the next item on the
+command line starts with a hyphen but is not an option. This allows for the
+processing of patterns and file names that start with hyphens.
+.TP
+\fB-A\fP \fInumber\fP, \fB--after-context=\fP\fInumber\fP
+Output up to \fInumber\fP lines of context after each matching line. Fewer
+lines are output if the next match or the end of the file is reached, or if the
+processing buffer size has been set too small. If file names and/or line
+numbers are being output, a hyphen separator is used instead of a colon for the
+context lines (the \fB-Z\fP option can be used to change the file name
+terminator to a zero byte). A line containing "--" is output between each group
+of lines, unless they are in fact contiguous in the input file. The value of
+\fInumber\fP is expected to be relatively small. When \fB-c\fP is used,
+\fB-A\fP is ignored.
+.TP
+\fB-a\fP, \fB--text\fP
+Treat binary files as text. This is equivalent to
+\fB--binary-files\fP=\fItext\fP.
+.TP
+\fB--allow-lookaround-bsk\fP
+PCRE2 now forbids the use of \eK in lookarounds by default, in line with Perl.
+This option causes \fBpcre2grep\fP to set the PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK
+option, which enables this somewhat dangerous usage.
+.TP
+\fB-B\fP \fInumber\fP, \fB--before-context=\fP\fInumber\fP
+Output up to \fInumber\fP lines of context before each matching line. Fewer
+lines are output if the previous match or the start of the file is within
+\fInumber\fP lines, or if the processing buffer size has been set too small. If
+file names and/or line numbers are being output, a hyphen separator is used
+instead of a colon for the context lines (the \fB-Z\fP option can be used to
+change the file name terminator to a zero byte). A line containing "--" is
+output between each group of lines, unless they are in fact contiguous in the
+input file. The value of \fInumber\fP is expected to be relatively small. When
+\fB-c\fP is used, \fB-B\fP is ignored.
+.TP
+\fB--binary-files=\fP\fIword\fP
+Specify how binary files are to be processed. If the word is "binary" (the
+default), pattern matching is performed on binary files, but the only output is
+"Binary file  matches" when a match succeeds. If the word is "text",
+which is equivalent to the \fB-a\fP or \fB--text\fP option, binary files are
+processed in the same way as any other file. In this case, when a match
+succeeds, the output may be binary garbage, which can have nasty effects if
+sent to a terminal. If the word is "without-match", which is equivalent to the
+\fB-I\fP option, binary files are not processed at all; they are assumed not to
+be of interest and are skipped without causing any output or affecting the
+return code.
+.TP
+\fB--buffer-size=\fP\fInumber\fP
+Set the parameter that controls how much memory is obtained at the start of
+processing for buffering files that are being scanned. See also
+\fB--max-buffer-size\fP below.
+.TP
+\fB-C\fP \fInumber\fP, \fB--context=\fP\fInumber\fP
+Output \fInumber\fP lines of context both before and after each matching line.
+This is equivalent to setting both \fB-A\fP and \fB-B\fP to the same value.
+.TP
+\fB-c\fP, \fB--count\fP
+Do not output lines from the files that are being scanned; instead output the
+number of lines that would have been shown, either because they matched, or, if
+\fB-v\fP is set, because they failed to match. By default, this count is
+exactly the same as the number of lines that would have been output, but if the
+\fB-M\fP (multiline) option is used (without \fB-v\fP), there may be more
+suppressed lines than the count (that is, the number of matches).
+.sp
+If no lines are selected, the number zero is output. If several files are
+being scanned, a count is output for each of them and the \fB-t\fP option can
+be used to cause a total to be output at the end. However, if the
+\fB--files-with-matches\fP option is also used, only those files whose counts
+are greater than zero are listed. When \fB-c\fP is used, the \fB-A\fP,
+\fB-B\fP, and \fB-C\fP options are ignored.
+.TP
+\fB--colour\fP, \fB--color\fP
+If this option is given without any data, it is equivalent to "--colour=auto".
+If data is required, it must be given in the same shell item, separated by an
+equals sign.
+.TP
+\fB--colour=\fP\fIvalue\fP, \fB--color=\fP\fIvalue\fP
+This option specifies under what circumstances the parts of a line that matched
+a pattern should be coloured in the output. It is ignored if
+\fB--file-offsets\fP, \fB--line-offsets\fP, or \fB--output\fP is set. By
+default, output is not coloured. The value for the \fB--colour\fP option (which
+is optional, see above) may be "never", "always", or "auto". In the latter
+case, colouring happens only if the standard output is connected to a terminal.
+More resources are used when colouring is enabled, because \fBpcre2grep\fP has
+to search for all possible matches in a line, not just one, in order to colour
+them all.
+.sp
+The colour that is used can be specified by setting one of the environment
+variables PCRE2GREP_COLOUR, PCRE2GREP_COLOR, PCREGREP_COLOUR, or
+PCREGREP_COLOR, which are checked in that order. If none of these are set,
+\fBpcre2grep\fP looks for GREP_COLORS or GREP_COLOR (in that order). The value
+of the variable should be a string of two numbers, separated by a semicolon,
+except in the case of GREP_COLORS, which must start with "ms=" or "mt="
+followed by two semicolon-separated colours, terminated by the end of the
+string or by a colon. If GREP_COLORS does not start with "ms=" or "mt=" it is
+ignored, and GREP_COLOR is checked.
+.sp
+If the string obtained from one of the above variables contains any characters
+other than semicolon or digits, the setting is ignored and the default colour
+is used. The string is copied directly into the control string for setting
+colour on a terminal, so it is your responsibility to ensure that the values
+make sense. If no relevant environment variable is set, the default is "1;31",
+which gives red.
+.TP
+\fB-D\fP \fIaction\fP, \fB--devices=\fP\fIaction\fP
+If an input path is not a regular file or a directory, "action" specifies how
+it is to be processed. Valid values are "read" (the default) or "skip"
+(silently skip the path).
+.TP
+\fB-d\fP \fIaction\fP, \fB--directories=\fP\fIaction\fP
+If an input path is a directory, "action" specifies how it is to be processed.
+Valid values are "read" (the default in non-Windows environments, for
+compatibility with GNU grep), "recurse" (equivalent to the \fB-r\fP option), or
+"skip" (silently skip the path, the default in Windows environments). In the
+"read" case, directories are read as if they were ordinary files. In some
+operating systems the effect of reading a directory like this is an immediate
+end-of-file; in others it may provoke an error.
+.TP
+\fB--depth-limit\fP=\fInumber\fP
+See \fB--match-limit\fP below.
+.TP
+\fB-E\fP, \fB--case-restrict\fP
+When case distinctions are being ignored in Unicode mode, two ASCII letters (K
+and S) will by default match Unicode characters U+212A (Kelvin sign) and U+017F
+(long S) respectively, as well as their lower case ASCII counterparts. When
+this option is set, case equivalences are restricted such that no ASCII
+character matches a non-ASCII character, and vice versa.
+.TP
+\fB-e\fP \fIpattern\fP, \fB--regex=\fP\fIpattern\fP, \fB--regexp=\fP\fIpattern\fP
+Specify a pattern to be matched. This option can be used multiple times in
+order to specify several patterns. It can also be used as a way of specifying a
+single pattern that starts with a hyphen. When \fB-e\fP is used, no argument
+pattern is taken from the command line; all arguments are treated as file
+names. There is no limit to the number of patterns. They are applied to each
+line in the order in which they are defined.
+.sp
+If \fB-f\fP is used with \fB-e\fP, the command line patterns are matched first,
+followed by the patterns from the file(s), independent of the order in which
+these options are specified.
+.TP
+\fB--exclude\fP=\fIpattern\fP
+Files (but not directories) whose names match the pattern are skipped without
+being processed. This applies to all files, whether listed on the command line,
+obtained from \fB--file-list\fP, or by scanning a directory. The pattern is a
+PCRE2 regular expression, and is matched against the final component of the
+file name, not the entire path. The \fB-F\fP, \fB-w\fP, and \fB-x\fP options do
+not apply to this pattern. The option may be given any number of times in order
+to specify multiple patterns. If a file name matches both an \fB--include\fP
+and an \fB--exclude\fP pattern, it is excluded. There is no short form for this
+option.
+.TP
+\fB--exclude-from=\fP\fIfilename\fP
+Treat each non-empty line of the file as the data for an \fB--exclude\fP
+option. What constitutes a newline when reading the file is the operating
+system's default. The \fB--newline\fP option has no effect on this option. This
+option may be given more than once in order to specify a number of files to
+read.
+.TP
+\fB--exclude-dir\fP=\fIpattern\fP
+Directories whose names match the pattern are skipped without being processed,
+whatever the setting of the \fB--recursive\fP option. This applies to all
+directories, whether listed on the command line, obtained from
+\fB--file-list\fP, or by scanning a parent directory. The pattern is a PCRE2
+regular expression, and is matched against the final component of the directory
+name, not the entire path. The \fB-F\fP, \fB-w\fP, and \fB-x\fP options do not
+apply to this pattern. The option may be given any number of times in order to
+specify more than one pattern. If a directory matches both \fB--include-dir\fP
+and \fB--exclude-dir\fP, it is excluded. There is no short form for this
+option.
+.TP
+\fB-F\fP, \fB--fixed-strings\fP
+Interpret each data-matching pattern as a list of fixed strings, separated by
+newlines, instead of as a regular expression. What constitutes a newline for
+this purpose is controlled by the \fB--newline\fP option. The \fB-w\fP (match
+as a word) and \fB-x\fP (match whole line) options can be used with \fB-F\fP.
+They apply to each of the fixed strings. A line is selected if any of the fixed
+strings are found in it (subject to \fB-w\fP or \fB-x\fP, if present). This
+option applies only to the patterns that are matched against the contents of
+files; it does not apply to patterns specified by any of the \fB--include\fP or
+\fB--exclude\fP options.
+.TP
+\fB-f\fP \fIfilename\fP, \fB--file=\fP\fIfilename\fP
+Read patterns from the file, one per line. As is the case with patterns on the
+command line, no delimiters should be used. What constitutes a newline when
+reading the file is the operating system's default interpretation of \en. The
+\fB--newline\fP option has no effect on this option. Trailing white space is
+removed from each line, and blank lines are ignored. An empty file contains no
+patterns and therefore matches nothing. Patterns read from a file in this way
+may contain binary zeros, which are treated as ordinary data characters.
+.sp
+If this option is given more than once, all the specified files are read. A
+data line is output if any of the patterns match it. A file name can be given
+as "-" to refer to the standard input. When \fB-f\fP is used, patterns
+specified on the command line using \fB-e\fP may also be present; they are
+matched before the file's patterns. However, no pattern is taken from the
+command line; all arguments are treated as the names of paths to be searched.
+.TP
+\fB--file-list\fP=\fIfilename\fP
+Read a list of files and/or directories that are to be scanned from the given
+file, one per line. What constitutes a newline when reading the file is the
+operating system's default. Trailing white space is removed from each line, and
+blank lines are ignored. These paths are processed before any that are listed
+on the command line. The file name can be given as "-" to refer to the standard
+input. If \fB--file\fP and \fB--file-list\fP are both specified as "-",
+patterns are read first. This is useful only when the standard input is a
+terminal, from which further lines (the list of files) can be read after an
+end-of-file indication. If this option is given more than once, all the
+specified files are read.
+.TP
+\fB--file-offsets\fP
+Instead of showing lines or parts of lines that match, show each match as an
+offset from the start of the file and a length, separated by a comma. In this
+mode, \fB--colour\fP has no effect, and no context is shown. That is, the
+\fB-A\fP, \fB-B\fP, and \fB-C\fP options are ignored. If there is more than one
+match in a line, each of them is shown separately. This option is mutually
+exclusive with \fB--output\fP, \fB--line-offsets\fP, and \fB--only-matching\fP.
+.TP
+\fB--group-separator\fP=\fItext\fP
+Output this text string instead of two hyphens between groups of lines when
+\fB-A\fP, \fB-B\fP, or \fB-C\fP is in use. See also \fB--no-group-separator\fP.
+.TP
+\fB-H\fP, \fB--with-filename\fP
+Force the inclusion of the file name at the start of output lines when
+searching a single file. The file name is not normally shown in this case.
+By default, for matching lines, the file name is followed by a colon; for
+context lines, a hyphen separator is used. The \fB-Z\fP option can be used to
+change the terminator to a zero byte. If a line number is also being output,
+it follows the file name. When the \fB-M\fP option causes a pattern to match
+more than one line, only the first is preceded by the file name. This option
+overrides any previous \fB-h\fP, \fB-l\fP, or \fB-L\fP options.
+.TP
+\fB-h\fP, \fB--no-filename\fP
+Suppress the output file names when searching multiple files. File names are
+normally shown when multiple files are searched. By default, for matching
+lines, the file name is followed by a colon; for context lines, a hyphen
+separator is used. The \fB-Z\fP option can be used to change the terminator to
+a zero byte. If a line number is also being output, it follows the file name.
+This option overrides any previous \fB-H\fP, \fB-L\fP, or \fB-l\fP options.
+.TP
+\fB--heap-limit\fP=\fInumber\fP
+See \fB--match-limit\fP below.
+.TP
+\fB--help\fP
+Output a help message, giving brief details of the command options and file
+type support, and then exit. Anything else on the command line is
+ignored.
+.TP
+\fB-I\fP
+Ignore binary files. This is equivalent to
+\fB--binary-files\fP=\fIwithout-match\fP.
+.TP
+\fB-i\fP, \fB--ignore-case\fP
+Ignore upper/lower case distinctions when pattern matching. This applies when
+matching path names for inclusion or exclusion as well as when matching lines
+in files.
+.TP
+\fB--include\fP=\fIpattern\fP
+If any \fB--include\fP patterns are specified, the only files that are
+processed are those whose names match one of the patterns and do not match an
+\fB--exclude\fP pattern. This option does not affect directories, but it
+applies to all files, whether listed on the command line, obtained from
+\fB--file-list\fP, or by scanning a directory. The pattern is a PCRE2 regular
+expression, and is matched against the final component of the file name, not
+the entire path. The \fB-F\fP, \fB-w\fP, and \fB-x\fP options do not apply to
+this pattern. The option may be given any number of times. If a file name
+matches both an \fB--include\fP and an \fB--exclude\fP pattern, it is excluded.
+There is no short form for this option.
+.TP
+\fB--include-from=\fP\fIfilename\fP
+Treat each non-empty line of the file as the data for an \fB--include\fP
+option. What constitutes a newline for this purpose is the operating system's
+default. The \fB--newline\fP option has no effect on this option. This option
+may be given any number of times; all the files are read.
+.TP
+\fB--include-dir\fP=\fIpattern\fP
+If any \fB--include-dir\fP patterns are specified, the only directories that
+are processed are those whose names match one of the patterns and do not match
+an \fB--exclude-dir\fP pattern. This applies to all directories, whether listed
+on the command line, obtained from \fB--file-list\fP, or by scanning a parent
+directory. The pattern is a PCRE2 regular expression, and is matched against
+the final component of the directory name, not the entire path. The \fB-F\fP,
+\fB-w\fP, and \fB-x\fP options do not apply to this pattern. The option may be
+given any number of times. If a directory matches both \fB--include-dir\fP and
+\fB--exclude-dir\fP, it is excluded. There is no short form for this option.
+.TP
+\fB-L\fP, \fB--files-without-match\fP
+Instead of outputting lines from the files, just output the names of the files
+that do not contain any lines that would have been output. Each file name is
+output once, on a separate line by default, but if the \fB-Z\fP option is set,
+they are separated by zero bytes instead of newlines. This option overrides any
+previous \fB-H\fP, \fB-h\fP, or \fB-l\fP options.
+.TP
+\fB-l\fP, \fB--files-with-matches\fP
+Instead of outputting lines from the files, just output the names of the files
+containing lines that would have been output. Each file name is output once, on
+a separate line, but if the \fB-Z\fP option is set, they are separated by zero
+bytes instead of newlines. Searching normally stops as soon as a matching line
+is found in a file. However, if the \fB-c\fP (count) option is also used,
+matching continues in order to obtain the correct count, and those files that
+have at least one match are listed along with their counts. Using this option
+with \fB-c\fP is a way of suppressing the listing of files with no matches that
+occurs with \fB-c\fP on its own. This option overrides any previous \fB-H\fP,
+\fB-h\fP, or \fB-L\fP options.
+.TP
+\fB--label\fP=\fIname\fP
+This option supplies a name to be used for the standard input when file names
+are being output. If not supplied, "(standard input)" is used. There is no
+short form for this option.
+.TP
+\fB--line-buffered\fP
+When this option is given, non-compressed input is read and processed line by
+line, and the output is flushed after each write. By default, input is read in
+large chunks, unless \fBpcre2grep\fP can determine that it is reading from a
+terminal, which is currently possible only in Unix-like environments or
+Windows. Output to terminal is normally automatically flushed by the operating
+system. This option can be useful when the input or output is attached to a
+pipe and you do not want \fBpcre2grep\fP to buffer up large amounts of data.
+However, its use will affect performance, and the \fB-M\fP (multiline) option
+ceases to work. When input is from a compressed .gz or .bz2 file,
+\fB--line-buffered\fP is ignored.
+.TP
+\fB--line-offsets\fP
+Instead of showing lines or parts of lines that match, show each match as a
+line number, the offset from the start of the line, and a length. The line
+number is terminated by a colon (as usual; see the \fB-n\fP option), and the
+offset and length are separated by a comma. In this mode, \fB--colour\fP has no
+effect, and no context is shown. That is, the \fB-A\fP, \fB-B\fP, and \fB-C\fP
+options are ignored. If there is more than one match in a line, each of them is
+shown separately. This option is mutually exclusive with \fB--output\fP,
+\fB--file-offsets\fP, and \fB--only-matching\fP.
+.TP
+\fB--locale\fP=\fIlocale-name\fP
+This option specifies a locale to be used for pattern matching. It overrides
+the value in the \fBLC_ALL\fP or \fBLC_CTYPE\fP environment variables. If no
+locale is specified, the PCRE2 library's default (usually the "C" locale) is
+used. There is no short form for this option.
+.TP
+\fB-M\fP, \fB--multiline\fP
+Allow patterns to match more than one line. When this option is set, the PCRE2
+library is called in "multiline" mode, and a match is allowed to continue past
+the end of the initial line and onto one or more subsequent lines.
+.sp
+Patterns used with \fB-M\fP may usefully contain literal newline characters and
+internal occurrences of ^ and $ characters, because in multiline mode these can
+match at internal newlines. Because \fBpcre2grep\fP is scanning multiple lines,
+the \eZ and \ez assertions match only at the end of the last line in the file.
+The \eA assertion matches at the start of the first line of a match. This can
+be any line in the file; it is not anchored to the first line.
+.sp
+The output for a successful match may consist of more than one line. The first
+line is the line in which the match started, and the last line is the line in
+which the match ended. If the matched string ends with a newline sequence, the
+output ends at the end of that line. If \fB-v\fP is set, none of the lines in a
+multi-line match are output. Once a match has been handled, scanning restarts
+at the beginning of the line after the one in which the match ended.
+.sp
+The newline sequence that separates multiple lines must be matched as part of
+the pattern. For example, to find the phrase "regular expression" in a file
+where "regular" might be at the end of a line and "expression" at the start of
+the next line, you could use this command:
+.sp
+  pcre2grep -M 'regular\es+expression' 
+.sp
+The \es escape sequence matches any white space character, including newlines,
+and is followed by + so as to match trailing white space on the first line as
+well as possibly handling a two-character newline sequence.
+.sp
+There is a limit to the number of lines that can be matched, imposed by the way
+that \fBpcre2grep\fP buffers the input file as it scans it. With a sufficiently
+large processing buffer, this should not be a problem.
+.sp
+The \fB-M\fP option does not work when input is read line by line (see
+\fB--line-buffered\fP.)
+.TP
+\fB-m\fP \fInumber\fP, \fB--max-count\fP=\fInumber\fP
+Stop processing after finding \fInumber\fP matching lines, or non-matching
+lines if \fB-v\fP is also set. Any trailing context lines are output after the
+final match. In multiline mode, each multiline match counts as just one line
+for this purpose. If this limit is reached when reading the standard input from
+a regular file, the file is left positioned just after the last matching line.
+If \fB-c\fP is also set, the count that is output is never greater than
+\fInumber\fP. This option has no effect if used with \fB-L\fP, \fB-l\fP, or
+\fB-q\fP, or when just checking for a match in a binary file.
+.TP
+\fB--match-limit\fP=\fInumber\fP
+Processing some regular expression patterns may take a very long time to search
+for all possible matching strings. Others may require a very large amount of
+memory. There are three options that set resource limits for matching.
+.sp
+The \fB--match-limit\fP option provides a means of limiting computing resource
+usage when processing patterns that are not going to match, but which have a
+very large number of possibilities in their search trees. The classic example
+is a pattern that uses nested unlimited repeats. Internally, PCRE2 has a
+counter that is incremented each time around its main processing loop. If the
+value set by \fB--match-limit\fP is reached, an error occurs.
+.sp
+The \fB--heap-limit\fP option specifies, as a number of kibibytes (units of
+1024 bytes), the maximum amount of heap memory that may be used for matching.
+.sp
+The \fB--depth-limit\fP option limits the depth of nested backtracking points,
+which indirectly limits the amount of memory that is used. The amount of memory
+needed for each backtracking point depends on the number of capturing
+parentheses in the pattern, so the amount of memory that is used before this
+limit acts varies from pattern to pattern. This limit is of use only if it is
+set smaller than \fB--match-limit\fP.
+.sp
+There are no short forms for these options. The default limits can be set
+when the PCRE2 library is compiled; if they are not specified, the defaults
+are very large and so effectively unlimited.
+.TP
+\fB--max-buffer-size\fP=\fInumber\fP
+This limits the expansion of the processing buffer, whose initial size can be
+set by \fB--buffer-size\fP. The maximum buffer size is silently forced to be no
+smaller than the starting buffer size.
+.TP
+\fB-N\fP \fInewline-type\fP, \fB--newline\fP=\fInewline-type\fP
+Six different conventions for indicating the ends of lines in scanned files are
+supported. For example:
+.sp
+  pcre2grep -N CRLF 'some pattern' 
+.sp
+The newline type may be specified in upper, lower, or mixed case. If the
+newline type is NUL, lines are separated by binary zero characters. The other
+types are the single-character sequences CR (carriage return) and LF
+(linefeed), the two-character sequence CRLF, an "anycrlf" type, which
+recognizes any of the preceding three types, and an "any" type, for which any
+Unicode line ending sequence is assumed to end a line. The Unicode sequences
+are the three just mentioned, plus VT (vertical tab, U+000B), FF (form feed,
+U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and PS
+(paragraph separator, U+2029).
+.sp
+When the PCRE2 library is built, a default line-ending sequence is specified.
+This is normally the standard sequence for the operating system. Unless
+otherwise specified by this option, \fBpcre2grep\fP uses the library's default.
+.sp
+This option makes it possible to use \fBpcre2grep\fP to scan files that have
+come from other environments without having to modify their line endings. If
+the data that is being scanned does not agree with the convention set by this
+option, \fBpcre2grep\fP may behave in strange ways. Note that this option does
+not apply to files specified by the \fB-f\fP, \fB--exclude-from\fP, or
+\fB--include-from\fP options, which are expected to use the operating system's
+standard newline sequence.
+.TP
+\fB-n\fP, \fB--line-number\fP
+Precede each output line by its line number in the file, followed by a colon
+for matching lines or a hyphen for context lines. If the file name is also
+being output, it precedes the line number. When the \fB-M\fP option causes a
+pattern to match more than one line, only the first is preceded by its line
+number. This option is forced if \fB--line-offsets\fP is used.
+.TP
+\fB--no-group-separator\fP
+Do not output a separator between groups of lines when \fB-A\fP, \fB-B\fP, or
+\fB-C\fP is in use. The default is to output a line containing two hyphens. See
+also \fB--group-separator\fP.
+.TP
+\fB--no-jit\fP
+If the PCRE2 library is built with support for just-in-time compiling (which
+speeds up matching), \fBpcre2grep\fP automatically makes use of this, unless it
+was explicitly disabled at build time. This option can be used to disable the
+use of JIT at run time. It is provided for testing and working around problems.
+It should never be needed in normal use.
+.TP
+\fB-O\fP \fItext\fP, \fB--output\fP=\fItext\fP
+When there is a match, instead of outputting the line that matched, output just
+the text specified in this option, followed by an operating-system standard
+newline. In this mode, \fB--colour\fP has no effect, and no context is shown.
+That is, the \fB-A\fP, \fB-B\fP, and \fB-C\fP options are ignored. The
+\fB--newline\fP option has no effect on this option, which is mutually
+exclusive with \fB--only-matching\fP, \fB--file-offsets\fP, and
+\fB--line-offsets\fP. However, like \fB--only-matching\fP, if there is more
+than one match in a line, each of them causes a line of output.
+.sp
+Escape sequences starting with a dollar character may be used to insert the
+contents of the matched part of the line and/or captured substrings into the
+text.
+.sp
+$ or ${} is replaced by the captured substring of the given
+decimal number; zero substitutes the whole match. If the number is greater than
+the number of capturing substrings, or if the capture is unset, the replacement
+is empty.
+.sp
+$a is replaced by bell; $b by backspace; $e by escape; $f by form feed; $n by
+newline; $r by carriage return; $t by tab; $v by vertical tab.
+.sp
+$o or $o{} is replaced by the character whose code point is the
+given octal number. In the first form, up to three octal digits are processed.
+When more digits are needed in Unicode mode to specify a wide character, the
+second form must be used.
+.sp
+$x or $x{} is replaced by the character represented by the
+given hexadecimal number. In the first form, up to two hexadecimal digits are
+processed. When more digits are needed in Unicode mode to specify a wide
+character, the second form must be used.
+.sp
+Any other character is substituted by itself. In particular, $$ is replaced by
+a single dollar.
+.TP
+\fB-o\fP, \fB--only-matching\fP
+Show only the part of the line that matched a pattern instead of the whole
+line. In this mode, no context is shown. That is, the \fB-A\fP, \fB-B\fP, and
+\fB-C\fP options are ignored. If there is more than one match in a line, each
+of them is shown separately, on a separate line of output. If \fB-o\fP is
+combined with \fB-v\fP (invert the sense of the match to find non-matching
+lines), no output is generated, but the return code is set appropriately. If
+the matched portion of the line is empty, nothing is output unless the file
+name or line number are being printed, in which case they are shown on an
+otherwise empty line. This option is mutually exclusive with \fB--output\fP,
+\fB--file-offsets\fP and \fB--line-offsets\fP.
+.TP
+\fB-o\fP\fInumber\fP, \fB--only-matching\fP=\fInumber\fP
+Show only the part of the line that matched the capturing parentheses of the
+given number. Up to 50 capturing parentheses are supported by default. This
+limit can be changed via the \fB--om-capture\fP option. A pattern may contain
+any number of capturing parentheses, but only those whose number is within the
+limit can be accessed by \fB-o\fP. An error occurs if the number specified by
+\fB-o\fP is greater than the limit.
+.sp
+-o0 is the same as \fB-o\fP without a number. Because these options can be
+given without an argument (see above), if an argument is present, it must be
+given in the same shell item, for example, -o3 or --only-matching=2. The
+comments given for the non-argument case above also apply to this option. If
+the specified capturing parentheses do not exist in the pattern, or were not
+set in the match, nothing is output unless the file name or line number are
+being output.
+.sp
+If this option is given multiple times, multiple substrings are output for each
+match, in the order the options are given, and all on one line. For example,
+-o3 -o1 -o3 causes the substrings matched by capturing parentheses 3 and 1 and
+then 3 again to be output. By default, there is no separator (but see the next
+but one option).
+.TP
+\fB--om-capture\fP=\fInumber\fP
+Set the number of capturing parentheses that can be accessed by \fB-o\fP. The
+default is 50.
+.TP
+\fB--om-separator\fP=\fItext\fP
+Specify a separating string for multiple occurrences of \fB-o\fP. The default
+is an empty string. Separating strings are never coloured.
+.TP
+\fB-P\fP, \fB--no-ucp\fP
+Starting from release 10.43, when UTF/Unicode mode is specified with \fB-u\fP
+or \fB-U\fP, the PCRE2_UCP option is used by default. This means that the
+POSIX classes in patterns match more than just ASCII characters. For example,
+[:digit:] matches any Unicode decimal digit. The \fB--no-ucp\fP option
+suppresses PCRE2_UCP, thus restricting the POSIX classes to ASCII characters,
+as was the case in earlier releases. Note that there are now more fine-grained
+option settings within patterns that affect individual classes. For example,
+when in UCP mode, the sequence (?aP) restricts [:word:] to ASCII letters, while
+allowing \ew to match Unicode letters and digits.
+.TP
+\fB-q\fP, \fB--quiet\fP
+Work quietly, that is, display nothing except error messages. The exit
+status indicates whether or not any matches were found.
+.TP
+\fB-r\fP, \fB--recursive\fP
+If any given path is a directory, recursively scan the files it contains,
+taking note of any \fB--include\fP and \fB--exclude\fP settings. By default, a
+directory is read as a normal file; in some operating systems this gives an
+immediate end-of-file. This option is a shorthand for setting the \fB-d\fP
+option to "recurse".
+.TP
+\fB--recursion-limit\fP=\fInumber\fP
+This is an obsolete synonym for \fB--depth-limit\fP. See \fB--match-limit\fP
+above for details.
+.TP
+\fB-s\fP, \fB--no-messages\fP
+Suppress error messages about non-existent or unreadable files. Such files are
+quietly skipped. However, the return code is still 2, even if matches were
+found in other files.
+.TP
+\fB-t\fP, \fB--total-count\fP
+This option is useful when scanning more than one file. If used on its own,
+\fB-t\fP suppresses all output except for a grand total number of matching
+lines (or non-matching lines if \fB-v\fP is used) in all the files. If \fB-t\fP
+is used with \fB-c\fP, a grand total is output except when the previous output
+is just one line. In other words, it is not output when just one file's count
+is listed. If file names are being output, the grand total is preceded by
+"TOTAL:". Otherwise, it appears as just another number. The \fB-t\fP option is
+ignored when used with \fB-L\fP (list files without matches), because the grand
+total would always be zero.
+.TP
+\fB-u\fP, \fB--utf\fP
+Operate in UTF/Unicode mode. This option is available only if PCRE2 has been
+compiled with UTF-8 support. All patterns (including those for any
+\fB--exclude\fP and \fB--include\fP options) and all lines that are scanned
+must be valid strings of UTF-8 characters. If an invalid UTF-8 string is
+encountered, an error occurs.
+.TP
+\fB-U\fP, \fB--utf-allow-invalid\fP
+As \fB--utf\fP, but in addition subject lines may contain invalid UTF-8 code
+unit sequences. These can never form part of any pattern match. Patterns
+themselves, however, must still be valid UTF-8 strings. This facility allows
+valid UTF-8 strings to be sought within arbitrary byte sequences in executable
+or other binary files. For more details about matching in non-valid UTF-8
+strings, see the
+.\" HREF
+\fBpcre2unicode\fP(3)
+.\"
+documentation.
+.TP
+\fB-V\fP, \fB--version\fP
+Write the version numbers of \fBpcre2grep\fP and the PCRE2 library to the
+standard output and then exit. Anything else on the command line is
+ignored.
+.TP
+\fB-v\fP, \fB--invert-match\fP
+Invert the sense of the match, so that lines which do \fInot\fP match any of
+the patterns are the ones that are found. When this option is set, options such
+as \fB--only-matching\fP and \fB--output\fP, which specify parts of a match
+that are to be output, are ignored.
+.TP
+\fB-w\fP, \fB--word-regex\fP, \fB--word-regexp\fP
+Force the patterns only to match "words". That is, there must be a word
+boundary at the start and end of each matched string. This is equivalent to
+having "\eb(?:" at the start of each pattern, and ")\eb" at the end. This
+option applies only to the patterns that are matched against the contents of
+files; it does not apply to patterns specified by any of the \fB--include\fP or
+\fB--exclude\fP options.
+.TP
+\fB-x\fP, \fB--line-regex\fP, \fB--line-regexp\fP
+Force the patterns to start matching only at the beginnings of lines, and in
+addition, require them to match entire lines. In multiline mode the match may
+be more than one line. This is equivalent to having "^(?:" at the start of each
+pattern and ")$" at the end. This option applies only to the patterns that are
+matched against the contents of files; it does not apply to patterns specified
+by any of the \fB--include\fP or \fB--exclude\fP options.
+.TP
+\fB-Z\fP, \fB--null\fP
+Terminate files names in the regular output with a zero byte (the NUL
+character) instead of what would normally appear. This is useful when file
+names contain unusual characters such as colons, hyphens, or even newlines. The
+option does not apply to file names in error messages.
+.
+.
+.SH "ENVIRONMENT VARIABLES"
+.rs
+.sp
+The environment variables \fBLC_ALL\fP and \fBLC_CTYPE\fP are examined, in that
+order, for a locale. The first one that is set is used. This can be overridden
+by the \fB--locale\fP option. If no locale is set, the PCRE2 library's default
+(usually the "C" locale) is used.
+.
+.
+.SH "NEWLINES"
+.rs
+.sp
+The \fB-N\fP (\fB--newline\fP) option allows \fBpcre2grep\fP to scan files with
+newline conventions that differ from the default. This option affects only the
+way scanned files are processed. It does not affect the interpretation of files
+specified by the \fB-f\fP, \fB--file-list\fP, \fB--exclude-from\fP, or
+\fB--include-from\fP options.
+.P
+Any parts of the scanned input files that are written to the standard output
+are copied with whatever newline sequences they have in the input. However, if
+the final line of a file is output, and it does not end with a newline
+sequence, a newline sequence is added. If the newline setting is CR, LF, CRLF
+or NUL, that line ending is output; for the other settings (ANYCRLF or ANY) a
+single NL is used.
+.P
+The newline setting does not affect the way in which \fBpcre2grep\fP writes
+newlines in informational messages to the standard output and error streams.
+Under Windows, the standard output is set to be binary, so that "\er\en" at the
+ends of output lines that are copied from the input is not converted to
+"\er\er\en" by the C I/O library. This means that any messages written to the
+standard output must end with "\er\en". For all other operating systems, and
+for all messages to the standard error stream, "\en" is used.
+.
+.
+.SH "OPTIONS COMPATIBILITY WITH GNU GREP"
+.rs
+.sp
+Many of the short and long forms of \fBpcre2grep\fP's options are the same as
+in the GNU \fBgrep\fP program. Any long option of the form \fB--xxx-regexp\fP
+(GNU terminology) is also available as \fB--xxx-regex\fP (PCRE2 terminology).
+However, the \fB--case-restrict\fP, \fB--depth-limit\fP, \fB-E\fP,
+\fB--file-list\fP, \fB--file-offsets\fP, \fB--heap-limit\fP,
+\fB--include-dir\fP, \fB--line-offsets\fP, \fB--locale\fP, \fB--match-limit\fP,
+\fB-M\fP, \fB--multiline\fP, \fB-N\fP, \fB--newline\fP, \fB--no-ucp\fP,
+\fB--om-separator\fP, \fB--output\fP, \fB-P\fP, \fB-u\fP, \fB--utf\fP,
+\fB-U\fP, and \fB--utf-allow-invalid\fP options are specific to
+\fBpcre2grep\fP, as is the use of the \fB--only-matching\fP option with a
+capturing parentheses number.
+.P
+Although most of the common options work the same way, a few are different in
+\fBpcre2grep\fP. For example, the \fB--include\fP option's argument is a glob
+for GNU \fBgrep\fP, but in \fBpcre2grep\fP it is a regular expression to which
+the \fB-i\fP option applies. If both the \fB-c\fP and \fB-l\fP options are
+given, GNU grep lists only file names, without counts, but \fBpcre2grep\fP
+gives the counts as well.
+.
+.
+.SH "OPTIONS WITH DATA"
+.rs
+.sp
+There are four different ways in which an option with data can be specified.
+If a short form option is used, the data may follow immediately, or (with one
+exception) in the next command line item. For example:
+.sp
+  -f/some/file
+  -f /some/file
+.sp
+The exception is the \fB-o\fP option, which may appear with or without data.
+Because of this, if data is present, it must follow immediately in the same
+item, for example -o3.
+.P
+If a long form option is used, the data may appear in the same command line
+item, separated by an equals character, or (with two exceptions) it may appear
+in the next command line item. For example:
+.sp
+  --file=/some/file
+  --file /some/file
+.sp
+Note, however, that if you want to supply a file name beginning with ~ as data
+in a shell command, and have the shell expand ~ to a home directory, you must
+separate the file name from the option, because the shell does not treat ~
+specially unless it is at the start of an item.
+.P
+The exceptions to the above are the \fB--colour\fP (or \fB--color\fP) and
+\fB--only-matching\fP options, for which the data is optional. If one of these
+options does have data, it must be given in the first form, using an equals
+character. Otherwise \fBpcre2grep\fP will assume that it has no data.
+.
+.
+.SH "USING PCRE2'S CALLOUT FACILITY"
+.rs
+.sp
+\fBpcre2grep\fP has, by default, support for calling external programs or
+scripts or echoing specific strings during matching by making use of PCRE2's
+callout facility. However, this support can be completely or partially disabled
+when \fBpcre2grep\fP is built. You can find out whether your binary has support
+for callouts by running it with the \fB--help\fP option. If callout support is
+completely disabled, all callouts in patterns are ignored by \fBpcre2grep\fP.
+If the facility is partially disabled, calling external programs is not
+supported, and callouts that request it are ignored.
+.P
+A callout in a PCRE2 pattern is of the form (?C) where the argument is
+either a number or a quoted string (see the
+.\" HREF
+\fBpcre2callout\fP
+.\"
+documentation for details). Numbered callouts are ignored by \fBpcre2grep\fP;
+only callouts with string arguments are useful.
+.
+.
+.SS "Echoing a specific string"
+.rs
+.sp
+Starting the callout string with a pipe character invokes an echoing facility
+that avoids calling an external program or script. This facility is always
+available, provided that callouts were not completely disabled when
+\fBpcre2grep\fP was built. The rest of the callout string is processed as a
+zero-terminated string, which means it should not contain any internal binary
+zeros. It is written to the output, having first been passed through the same
+escape processing as text from the \fB--output\fP (\fB-O\fP) option (see
+above). However, $0 cannot be used to insert a matched substring because the
+match is still in progress. Instead, the single character '0' is inserted. Any
+syntax errors in the string (for example, a dollar not followed by another
+character) causes the callout to be ignored. No terminator is added to the
+output string, so if you want a newline, you must include it explicitly using
+the escape $n. For example:
+.sp
+  pcre2grep '(.)(..(.))(?C"|[$1] [$2] [$3]$n")' 
+.sp
+Matching continues normally after the string is output. If you want to see only
+the callout output but not any output from an actual match, you should end the
+pattern with (*FAIL).
+.
+.
+.SS "Calling external programs or scripts"
+.rs
+.sp
+This facility can be independently disabled when \fBpcre2grep\fP is built. It
+is supported for Windows, where a call to \fB_spawnvp()\fP is used, for VMS,
+where \fBlib$spawn()\fP is used, and for any Unix-like environment where
+\fBfork()\fP and \fBexecv()\fP are available.
+.P
+If the callout string does not start with a pipe (vertical bar) character, it
+is parsed into a list of substrings separated by pipe characters. The first
+substring must be an executable name, with the following substrings specifying
+arguments:
+.sp
+  executable_name|arg1|arg2|...
+.sp
+Any substring (including the executable name) may contain escape sequences
+started by a dollar character. These are the same as for the \fB--output\fP
+(\fB-O\fP) option documented above, except that $0 cannot insert the matched
+string because the match is still in progress. Instead, the character '0'
+is inserted. If you need a literal dollar or pipe character in any
+substring, use $$ or $| respectively. Here is an example:
+.sp
+  echo -e "abcde\en12345" | pcre2grep \e
+    '(?x)(.)(..(.))
+    (?C"/bin/echo|Arg1: [$1] [$2] [$3]|Arg2: $|${1}$| ($4)")()' -
+.sp
+  Output:
+.sp
+    Arg1: [a] [bcd] [d] Arg2: |a| ()
+    abcde
+    Arg1: [1] [234] [4] Arg2: |1| ()
+    12345
+.sp
+The parameters for the system call that is used to run the program or script
+are zero-terminated strings. This means that binary zero characters in the
+callout argument will cause premature termination of their substrings, and
+therefore should not be present. Any syntax errors in the string (for example,
+a dollar not followed by another character) causes the callout to be ignored.
+If running the program fails for any reason (including the non-existence of the
+executable), a local matching failure occurs and the matcher backtracks in the
+normal way.
+.
+.
+.SH "MATCHING ERRORS"
+.rs
+.sp
+It is possible to supply a regular expression that takes a very long time to
+fail to match certain lines. Such patterns normally involve nested indefinite
+repeats, for example: (a+)*\ed when matched against a line of a's with no final
+digit. The PCRE2 matching function has a resource limit that causes it to abort
+in these circumstances. If this happens, \fBpcre2grep\fP outputs an error
+message and the line that caused the problem to the standard error stream. If
+there are more than 20 such errors, \fBpcre2grep\fP gives up.
+.P
+The \fB--match-limit\fP option of \fBpcre2grep\fP can be used to set the
+overall resource limit. There are also other limits that affect the amount of
+memory used during matching; see the discussion of \fB--heap-limit\fP and
+\fB--depth-limit\fP above.
+.
+.
+.SH DIAGNOSTICS
+.rs
+.sp
+Exit status is 0 if any matches were found, 1 if no matches were found, and 2
+for syntax errors, overlong lines, non-existent or inaccessible files (even if
+matches were found in other files) or too many matching errors. Using the
+\fB-s\fP option to suppress error messages about inaccessible files does not
+affect the return code.

+When run under VMS, the return code is placed in the symbol PCRE2GREP_RC

+PCRE2GREP(1)                General Commands Manual               PCRE2GREP(1)
+
+
+NAME
+       pcre2grep - a grep with Perl-compatible regular expressions.
+
+
+SYNOPSIS
+       pcre2grep [options] [long options] [pattern] [path1 path2 ...]
+
+
+DESCRIPTION
+
+       pcre2grep  searches  files  for  character patterns, in the same way as
+       other grep commands do, but it uses the PCRE2  regular  expression  li-
+       brary  to support patterns that are compatible with the regular expres-
+       sions of Perl 5. See pcre2syntax(3) for a  quick-reference  summary  of
+       pattern syntax, or pcre2pattern(3) for a full description of the syntax
+       and semantics of the regular expressions that PCRE2 supports.
+
+       Patterns,  whether  supplied on the command line or in a separate file,
+       are given without delimiters. For example:
+
+         pcre2grep Thursday /etc/motd
+
+       If you attempt to use delimiters (for example, by surrounding a pattern
+       with slashes, as is common in Perl scripts), they  are  interpreted  as
+       part  of  the pattern. Quotes can of course be used to delimit patterns
+       on the command line because they are interpreted by the shell, and  in-
+       deed  quotes  are  required  if a pattern contains white space or shell
+       metacharacters.
+
+       The first argument that follows any option settings is treated  as  the
+       single  pattern  to be matched when neither -e nor -f is present.  Con-
+       versely, when one or both of these options are  used  to  specify  pat-
+       terns, all arguments are treated as path names. At least one of -e, -f,
+       or an argument pattern must be provided.
+
+       If  no  files  are  specified,  pcre2grep reads the standard input. The
+       standard input can also be referenced by a name consisting of a  single
+       hyphen.  For example:
+
+         pcre2grep some-pattern file1 - file3
+
+       By  default,  input  files are searched line by line, so pattern asser-
+       tions about the beginning and end of a subject string (^,  $,  \A,  \Z,
+       and  \z)  match  at  the  beginning  and  end of each line. When a line
+       matches a pattern, it is copied to the standard output, and if there is
+       more than one file, the file name is output at the start of each  line,
+       followed  by  a  colon.  However, there are options that can change how
+       pcre2grep behaves. For example, the -M  option  makes  it  possible  to
+       search  for  strings  that  span  line  boundaries. What defines a line
+       boundary is controlled by the -N (--newline) option.  The -h and -H op-
+       tions control whether or not file names are shown, and  the  -Z  option
+       changes the file name terminator to a zero byte.
+
+       The amount of memory used for buffering files that are being scanned is
+       controlled  by  parameters  that  can  be  set by the --buffer-size and
+       --max-buffer-size options. The first of these sets the size  of  buffer
+       that  is obtained at the start of processing. If an input file contains
+       very long lines, a larger buffer may be needed; this is handled by  au-
+       tomatically  extending  the buffer, up to the limit specified by --max-
+       buffer-size. The default values for these parameters can  be  set  when
+       pcre2grep  is  built;  if nothing is specified, the defaults are set to
+       20KiB and 1MiB respectively. An error occurs if a line is too long  and
+       the buffer can no longer be expanded.
+
+       The  block  of  memory that is actually used is three times the "buffer
+       size", to allow for buffering "before" and "after" lines. If the buffer
+       size is too small, fewer than requested "before" and "after" lines  may
+       be output.
+
+       When  matching with a multiline pattern, the size of the buffer must be
+       at least half of the maximum match expected or the pattern  might  fail
+       to match.
+
+       Patterns  can  be no longer than 8KiB or BUFSIZ bytes, whichever is the
+       greater.  BUFSIZ is defined in . When there is more  than  one
+       pattern (specified by the use of -e and/or -f), each pattern is applied
+       to  each  line  in the order in which they are defined, except that all
+       the -e patterns are tried before the -f patterns.
+
+       By default, as soon as one pattern matches a line, no further  patterns
+       are considered. However, if --colour (or --color) is used to colour the
+       matching substrings, or if --only-matching, --file-offsets, --line-off-
+       sets,  or  --output  is  used  to output only the part of the line that
+       matched (either shown literally, or as an  offset),  the  behaviour  is
+       different. In this situation, all the patterns are applied to the line.
+       If  there  is  more  than one match, the one that begins nearest to the
+       start of the subject is processed; if there is more than one  match  at
+       that   position,  the  one  with  the  longest  matching  substring  is
+       processed; if the matching substrings are equal, the first match  found
+       is processed.
+
+       Scanning with all the patterns resumes immediately following the match,
+       so  that  later  matches  on the same line can be found. Note, however,
+       that an overlapping match that starts in the middle  of  another  match
+       will not be processed.
+
+       The  above behaviour was changed at release 10.41 to be more compatible
+       with GNU grep. In earlier releases, pcre2grep did not recognize matches
+       from later patterns that were earlier in the subject.
+
+       Patterns that can match an empty string are accepted, but empty  string
+       matches   are  never  recognized.  An  example  is  the  pattern  "(su-
+       per)?(man)?", in which all components are optional. This pattern  finds
+       all  occurrences  of  both  "super"  and "man"; the output differs from
+       matching with "super|man" when only the matching substrings  are  being
+       shown.
+
+       If  the  LC_ALL or LC_CTYPE environment variable is set, pcre2grep uses
+       the value to set a locale when calling the PCRE2 library.  The --locale
+       option can be used to override this.
+
+
+SUPPORT FOR COMPRESSED FILES
+
+       Compile-time options for pcre2grep can set it up to use libz or  libbz2
+       for  reading  compressed  files whose names end in .gz or .bz2, respec-
+       tively. You can find out whether your pcre2grep binary has support  for
+       one  or  both of these file types by running it with the --help option.
+       If the appropriate support is not present, all  files  are  treated  as
+       plain  text.  The standard input is always so treated. If a file with a
+       .gz or .bz2 extension is not in fact compressed, it is read as a  plain
+       text  file.  When  input  is  from  a  compressed .gz or .bz2 file, the
+       --line-buffered option is ignored.
+
+
+BINARY FILES
+
+       By default, a file that contains a binary zero byte  within  the  first
+       1024  bytes is identified as a binary file, and is processed specially.
+       However, if the newline type is specified as NUL,  that  is,  the  line
+       terminator is a binary zero, the test for a binary file is not applied.
+       See  the  --binary-files  option for a means of changing the way binary
+       files are handled.
+
+
+BINARY ZEROS IN PATTERNS
+
+       Patterns passed from the command line are strings that  are  terminated
+       by  a  binary zero, so cannot contain internal zeros. However, patterns
+       that are read from a file via the -f option may contain binary zeros.
+
+
+OPTIONS
+
+       The order in which some of the options appear can  affect  the  output.
+       For  example,  both  the  -H and -l options affect the printing of file
+       names. Whichever comes later in the command line will be the  one  that
+       takes  effect.  Similarly,  except  where  noted below, if an option is
+       given twice, the later setting is used. Numerical  values  for  options
+       may  be  followed  by  K  or  M,  to  signify multiplication by 1024 or
+       1024*1024 respectively.
+
+       --        This terminates the list of options. It is useful if the next
+                 item on the command line starts with a hyphen but is  not  an
+                 option.  This  allows for the processing of patterns and file
+                 names that start with hyphens.
+
+       -A number, --after-context=number
+                 Output up to number lines  of  context  after  each  matching
+                 line.  Fewer lines are output if the next match or the end of
+                 the file is reached, or if the  processing  buffer  size  has
+                 been set too small. If file names and/or line numbers are be-
+                 ing output, a hyphen separator is used instead of a colon for
+                 the  context  lines  (the -Z option can be used to change the
+                 file name terminator to a zero byte). A line containing  "--"
+                 is  output  between  each  group of lines, unless they are in
+                 fact contiguous in the input file. The value of number is ex-
+                 pected to be relatively small. When -c is  used,  -A  is  ig-
+                 nored.
+
+       -a, --text
+                 Treat  binary  files as text. This is equivalent to --binary-
+                 files=text.
+
+       --allow-lookaround-bsk
+                 PCRE2 now forbids the use of \K in lookarounds by default, in
+                 line with Perl.  This option  causes  pcre2grep  to  set  the
+                 PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK  option,  which enables this
+                 somewhat dangerous usage.
+
+       -B number, --before-context=number
+                 Output up to number lines of  context  before  each  matching
+                 line.  Fewer  lines  are  output if the previous match or the
+                 start of the file is within number lines, or if the  process-
+                 ing  buffer size has been set too small. If file names and/or
+                 line numbers are being output, a hyphen separator is used in-
+                 stead of a colon for the context lines (the -Z option can  be
+                 used  to  change  the file name terminator to a zero byte). A
+                 line containing "--" is output between each group  of  lines,
+                 unless  they  are  in  fact contiguous in the input file. The
+                 value of number is expected to be relatively small.  When  -c
+                 is used, -B is ignored.
+
+       --binary-files=word
+                 Specify  how binary files are to be processed. If the word is
+                 "binary" (the default), pattern matching is performed on  bi-
+                 nary  files,  but  the  only  output  is  "Binary file 
+                 matches" when a match succeeds. If the word is "text",  which
+                 is  equivalent  to  the -a or --text option, binary files are
+                 processed in the same way as any other file.  In  this  case,
+                 when  a  match  succeeds,  the  output may be binary garbage,
+                 which can have nasty effects if sent to a  terminal.  If  the
+                 word  is  "without-match",  which is equivalent to the -I op-
+                 tion, binary files are not processed at all; they are assumed
+                 not to be of interest and are  skipped  without  causing  any
+                 output or affecting the return code.
+
+       --buffer-size=number
+                 Set  the  parameter that controls how much memory is obtained
+                 at the start of processing for buffering files that are being
+                 scanned. See also --max-buffer-size below.
+
+       -C number, --context=number
+                 Output number lines of context both  before  and  after  each
+                 matching  line.  This is equivalent to setting both -A and -B
+                 to the same value.
+
+       -c, --count
+                 Do not output lines from the files that  are  being  scanned;
+                 instead  output  the  number  of  lines  that would have been
+                 shown, either because they matched, or, if -v is set, because
+                 they failed to match. By default, this count is  exactly  the
+                 same  as the number of lines that would have been output, but
+                 if the -M (multiline) option is used (without -v), there  may
+                 be  more suppressed lines than the count (that is, the number
+                 of matches).
+
+                 If no lines are selected, the number zero is output. If  sev-
+                 eral  files  are being scanned, a count is output for each of
+                 them and the -t option can be used to cause  a  total  to  be
+                 output  at  the end. However, if the --files-with-matches op-
+                 tion is also used, only those files whose counts are  greater
+                 than zero are listed. When -c is used, the -A, -B, and -C op-
+                 tions are ignored.
+
+       --colour, --color
+                 If this option is given without any data, it is equivalent to
+                 "--colour=auto".   If  data  is required, it must be given in
+                 the same shell item, separated by an equals sign.
+
+       --colour=value, --color=value
+                 This option specifies under what circumstances the parts of a
+                 line that matched a pattern should be coloured in the output.
+                 It is ignored if --file-offsets, --line-offsets, or  --output
+                 is set. By default, output is not coloured. The value for the
+                 --colour  option  (which  is  optional,  see  above)  may  be
+                 "never", "always", or "auto". In the latter  case,  colouring
+                 happens  only if the standard output is connected to a termi-
+                 nal.  More resources are used when colouring is enabled,  be-
+                 cause  pcre2grep  has to search for all possible matches in a
+                 line, not just one, in order to colour them all.
+
+                 The colour that is used can be specified by  setting  one  of
+                 the  environment variables PCRE2GREP_COLOUR, PCRE2GREP_COLOR,
+                 PCREGREP_COLOUR, or PCREGREP_COLOR, which are checked in that
+                 order.  If  none  of  these  are  set,  pcre2grep  looks  for
+                 GREP_COLORS  or  GREP_COLOR (in that order). The value of the
+                 variable should be a string of two numbers,  separated  by  a
+                 semicolon,  except  in  the  case  of GREP_COLORS, which must
+                 start with "ms=" or "mt=" followed by two semicolon-separated
+                 colours, terminated by the end of the string or by  a  colon.
+                 If  GREP_COLORS  does not start with "ms=" or "mt=" it is ig-
+                 nored, and GREP_COLOR is checked.
+
+                 If the string obtained from one of the above  variables  con-
+                 tains any characters other than semicolon or digits, the set-
+                 ting is ignored and the default colour is used. The string is
+                 copied directly into the control string for setting colour on
+                 a  terminal,  so it is your responsibility to ensure that the
+                 values make sense. If no  relevant  environment  variable  is
+                 set, the default is "1;31", which gives red.
+
+       -D action, --devices=action
+                 If  an  input path is not a regular file or a directory, "ac-
+                 tion" specifies how it is to be processed. Valid  values  are
+                 "read" (the default) or "skip" (silently skip the path).
+
+       -d action, --directories=action
+                 If an input path is a directory, "action" specifies how it is
+                 to  be  processed.   Valid  values are "read" (the default in
+                 non-Windows environments, for compatibility with  GNU  grep),
+                 "recurse"  (equivalent to the -r option), or "skip" (silently
+                 skip the path, the default in Windows environments).  In  the
+                 "read"  case,  directories  are read as if they were ordinary
+                 files. In some operating systems the effect of reading a  di-
+                 rectory  like  this is an immediate end-of-file; in others it
+                 may provoke an error.
+
+       --depth-limit=number
+                 See --match-limit below.
+
+       -E, --case-restrict
+                 When case distinctions are being ignored in Unicode mode, two
+                 ASCII letters (K and S) will by default match Unicode charac-
+                 ters U+212A (Kelvin sign) and U+017F (long  S)  respectively,
+                 as well as their lower case ASCII counterparts. When this op-
+                 tion  is  set,  case equivalences are restricted such that no
+                 ASCII character  matches  a  non-ASCII  character,  and  vice
+                 versa.
+
+       -e pattern, --regex=pattern, --regexp=pattern
+                 Specify a pattern to be matched. This option can be used mul-
+                 tiple times in order to specify several patterns. It can also
+                 be  used  as a way of specifying a single pattern that starts
+                 with a hyphen. When -e is used, no argument pattern is  taken
+                 from  the  command  line;  all  arguments are treated as file
+                 names. There is no limit to the number of patterns. They  are
+                 applied to each line in the order in which they are defined.
+
+                 If  -f is used with -e, the command line patterns are matched
+                 first, followed by the patterns from the file(s), independent
+                 of the order in which these options are specified.
+
+       --exclude=pattern
+                 Files (but not directories) whose names match the pattern are
+                 skipped without being processed. This applies to  all  files,
+                 whether  listed  on  the  command line, obtained from --file-
+                 list, or by scanning a directory. The pattern is a PCRE2 reg-
+                 ular expression, and is matched against the  final  component
+                 of the file name, not the entire path. The -F, -w, and -x op-
+                 tions  do  not apply to this pattern. The option may be given
+                 any number of times in order to specify multiple patterns. If
+                 a file name matches both an --include and an  --exclude  pat-
+                 tern, it is excluded. There is no short form for this option.
+
+       --exclude-from=filename
+                 Treat  each  non-empty  line  of  the file as the data for an
+                 --exclude option. What constitutes a newline when reading the
+                 file is the operating system's default. The --newline  option
+                 has  no  effect on this option. This option may be given more
+                 than once in order to specify a number of files to read.
+
+       --exclude-dir=pattern
+                 Directories whose names match the pattern are skipped without
+                 being processed, whatever the setting of the --recursive  op-
+                 tion.  This applies to all directories, whether listed on the
+                 command line, obtained from --file-list,  or  by  scanning  a
+                 parent  directory. The pattern is a PCRE2 regular expression,
+                 and is matched against the final component of  the  directory
+                 name,  not the entire path. The -F, -w, and -x options do not
+                 apply to this pattern. The option may be given any number  of
+                 times  in order to specify more than one pattern. If a direc-
+                 tory matches both --include-dir and --exclude-dir, it is  ex-
+                 cluded. There is no short form for this option.
+
+       -F, --fixed-strings
+                 Interpret  each  data-matching  pattern  as  a  list of fixed
+                 strings, separated by newlines, instead of as a  regular  ex-
+                 pression. What constitutes a newline for this purpose is con-
+                 trolled by the --newline option. The -w (match as a word) and
+                 -x  (match whole line) options can be used with -F.  They ap-
+                 ply to each of the fixed strings. A line is selected  if  any
+                 of the fixed strings are found in it (subject to -w or -x, if
+                 present).  This  option applies only to the patterns that are
+                 matched against the contents of files; it does not  apply  to
+                 patterns  specified  by any of the --include or --exclude op-
+                 tions.
+
+       -f filename, --file=filename
+                 Read patterns from the file, one per line.  As  is  the  case
+                 with  patterns  on  the command line, no delimiters should be
+                 used. What constitutes a newline when reading the file is the
+                 operating system's default interpretation of \n.  The  --new-
+                 line  option  has  no  effect  on this option. Trailing white
+                 space is removed from each line, and blank lines are ignored.
+                 An empty file contains  no  patterns  and  therefore  matches
+                 nothing.  Patterns  read  from a file in this way may contain
+                 binary zeros, which are treated as ordinary data characters.
+
+                 If this option is given more than  once,  all  the  specified
+                 files  are read. A data line is output if any of the patterns
+                 match it. A file name can be given as "-"  to  refer  to  the
+                 standard  input.  When  -f is used, patterns specified on the
+                 command line using -e may also be present; they  are  matched
+                 before the file's patterns. However, no pattern is taken from
+                 the  command  line; all arguments are treated as the names of
+                 paths to be searched.
+
+       --file-list=filename
+                 Read a list of  files  and/or  directories  that  are  to  be
+                 scanned from the given file, one per line. What constitutes a
+                 newline  when  reading the file is the operating system's de-
+                 fault. Trailing white space is removed from  each  line,  and
+                 blank lines are ignored. These paths are processed before any
+                 that  are  listed  on  the command line. The file name can be
+                 given as "-" to refer to the standard input.  If  --file  and
+                 --file-list  are  both  specified  as  "-", patterns are read
+                 first. This is useful only when the standard input is a  ter-
+                 minal,  from  which  further lines (the list of files) can be
+                 read after an end-of-file indication. If this option is given
+                 more than once, all the specified files are read.
+
+       --file-offsets
+                 Instead of showing lines or parts of lines that  match,  show
+                 each  match  as  an  offset  from the start of the file and a
+                 length, separated by a comma. In this mode, --colour  has  no
+                 effect,  and no context is shown. That is, the -A, -B, and -C
+                 options are ignored. If there is more than  one  match  in  a
+                 line,  each of them is shown separately. This option is mutu-
+                 ally exclusive with  --output,  --line-offsets,  and  --only-
+                 matching.
+
+       --group-separator=text
+                 Output this text string instead of two hyphens between groups
+                 of  lines  when -A, -B, or -C is in use. See also --no-group-
+                 separator.
+
+       -H, --with-filename
+                 Force the inclusion of the file name at the start  of  output
+                 lines when searching a single file. The file name is not nor-
+                 mally  shown  in  this case.  By default, for matching lines,
+                 the file name is followed by a colon; for  context  lines,  a
+                 hyphen separator is used. The -Z option can be used to change
+                 the terminator to a zero byte. If a line number is also being
+                 output, it follows the file name. When the -M option causes a
+                 pattern  to  match more than one line, only the first is pre-
+                 ceded by the file name. This option  overrides  any  previous
+                 -h, -l, or -L options.
+
+       -h, --no-filename
+                 Suppress the output file names when searching multiple files.
+                 File  names  are  normally  shown  when  multiple  files  are
+                 searched. By default, for matching lines, the  file  name  is
+                 followed by a colon; for context lines, a hyphen separator is
+                 used. The -Z option can be used to change the terminator to a
+                 zero  byte. If a line number is also being output, it follows
+                 the file name.  This option overrides any previous -H, -L, or
+                 -l options.
+
+       --heap-limit=number
+                 See --match-limit below.
+
+       --help    Output a help message, giving brief details  of  the  command
+                 options  and  file type support, and then exit. Anything else
+                 on the command line is ignored.
+
+       -I        Ignore  binary  files.  This  is  equivalent   to   --binary-
+                 files=without-match.
+
+       -i, --ignore-case
+                 Ignore  upper/lower  case distinctions when pattern matching.
+                 This applies when matching path names for inclusion or exclu-
+                 sion as well as when matching lines in files.
+
+       --include=pattern
+                 If any --include patterns are specified, the only files  that
+                 are processed are those whose names match one of the patterns
+                 and  do  not match an --exclude pattern. This option does not
+                 affect directories, but it  applies  to  all  files,  whether
+                 listed  on the command line, obtained from --file-list, or by
+                 scanning a directory. The pattern is a PCRE2 regular  expres-
+                 sion,  and is matched against the final component of the file
+                 name, not the entire path. The -F, -w, and -x options do  not
+                 apply  to this pattern. The option may be given any number of
+                 times. If a file name matches both an --include and an  --ex-
+                 clude  pattern,  it  is excluded.  There is no short form for
+                 this option.
+
+       --include-from=filename
+                 Treat each non-empty line of the file  as  the  data  for  an
+                 --include option. What constitutes a newline for this purpose
+                 is  the  operating system's default. The --newline option has
+                 no effect on this option. This option may be given any number
+                 of times; all the files are read.
+
+       --include-dir=pattern
+                 If any --include-dir patterns are specified, the only  direc-
+                 tories  that are processed are those whose names match one of
+                 the patterns and do not match an --exclude-dir pattern.  This
+                 applies  to  all  directories,  whether listed on the command
+                 line, obtained from --file-list, or by scanning a parent  di-
+                 rectory.  The  pattern  is a PCRE2 regular expression, and is
+                 matched against the final component of  the  directory  name,
+                 not  the entire path. The -F, -w, and -x options do not apply
+                 to this pattern. The option may be given any number of times.
+                 If a directory matches both --include-dir and  --exclude-dir,
+                 it is excluded. There is no short form for this option.
+
+       -L, --files-without-match
+                 Instead  of  outputting lines from the files, just output the
+                 names of the files that do not contain any lines  that  would
+                 have  been  output. Each file name is output once, on a sepa-
+                 rate line by default, but if the -Z option is set,  they  are
+                 separated  by  zero  bytes  instead  of newlines. This option
+                 overrides any previous -H, -h, or -l options.
+
+       -l, --files-with-matches
+                 Instead of outputting lines from the files, just  output  the
+                 names of the files containing lines that would have been out-
+                 put.  Each  file name is output once, on a separate line, but
+                 if the -Z option is set, they are separated by zero bytes in-
+                 stead of newlines. Searching normally  stops  as  soon  as  a
+                 matching  line is found in a file. However, if the -c (count)
+                 option is also used, matching continues in  order  to  obtain
+                 the  correct  count,  and  those files that have at least one
+                 match are listed along with their counts. Using  this  option
+                 with  -c is a way of suppressing the listing of files with no
+                 matches that occurs with -c on its own. This option overrides
+                 any previous -H, -h, or -L options.
+
+       --label=name
+                 This option supplies a name to be used for the standard input
+                 when file names are being output. If not supplied, "(standard
+                 input)" is used. There is no short form for this option.
+
+       --line-buffered
+                 When this option is given, non-compressed input is  read  and
+                 processed  line by line, and the output is flushed after each
+                 write. By default, input is  read  in  large  chunks,  unless
+                 pcre2grep  can  determine that it is reading from a terminal,
+                 which is currently possible only in Unix-like environments or
+                 Windows. Output to terminal is normally automatically flushed
+                 by the operating system. This option can be useful  when  the
+                 input  or  output  is  attached to a pipe and you do not want
+                 pcre2grep to buffer up large amounts of data.   However,  its
+                 use  will  affect  performance, and the -M (multiline) option
+                 ceases to work. When input is from a compressed .gz  or  .bz2
+                 file, --line-buffered is ignored.
+
+       --line-offsets
+                 Instead  of  showing lines or parts of lines that match, show
+                 each match as a line number, the offset from the start of the
+                 line, and a length. The line number is terminated by a  colon
+                 (as  usual; see the -n option), and the offset and length are
+                 separated by a comma. In this mode, --colour has  no  effect,
+                 and  no context is shown. That is, the -A, -B, and -C options
+                 are ignored. If there is more than one match in a line,  each
+                 of  them  is shown separately. This option is mutually exclu-
+                 sive with --output, --file-offsets, and --only-matching.
+
+       --locale=locale-name
+                 This option specifies a locale to be used for pattern  match-
+                 ing.  It  overrides the value in the LC_ALL or LC_CTYPE envi-
+                 ronment variables. If no locale is specified, the  PCRE2  li-
+                 brary's default (usually the "C" locale) is used. There is no
+                 short form for this option.
+
+       -M, --multiline
+                 Allow  patterns to match more than one line. When this option
+                 is set, the PCRE2 library is called in "multiline" mode,  and
+                 a  match  is  allowed to continue past the end of the initial
+                 line and onto one or more subsequent lines.
+
+                 Patterns used with -M may usefully  contain  literal  newline
+                 characters  and  internal  occurrences of ^ and $ characters,
+                 because in multiline mode these can match  at  internal  new-
+                 lines.  Because  pcre2grep is scanning multiple lines, the \Z
+                 and \z assertions match only at the end of the last  line  in
+                 the file.  The \A assertion matches at the start of the first
+                 line  of a match. This can be any line in the file; it is not
+                 anchored to the first line.
+
+                 The output for a successful match may consist  of  more  than
+                 one  line.  The  first  line  is  the line in which the match
+                 started, and the last line is the line  in  which  the  match
+                 ended.  If  the  matched string ends with a newline sequence,
+                 the output ends at the end of that line. If -v is  set,  none
+                 of  the  lines in a multi-line match are output. Once a match
+                 has been handled, scanning restarts at the beginning  of  the
+                 line after the one in which the match ended.
+
+                 The  newline  sequence  that separates multiple lines must be
+                 matched as part of the pattern.  For  example,  to  find  the
+                 phrase  "regular  expression" in a file where "regular" might
+                 be at the end of a line and "expression" at the start of  the
+                 next line, you could use this command:
+
+                   pcre2grep -M 'regular\s+expression' 
+
+                 The \s escape sequence matches any white space character, in-
+                 cluding  newlines, and is followed by + so as to match trail-
+                 ing white space on the first line as well  as  possibly  han-
+                 dling a two-character newline sequence.
+
+                 There  is a limit to the number of lines that can be matched,
+                 imposed by the way that pcre2grep buffers the input  file  as
+                 it  scans  it.  With  a sufficiently large processing buffer,
+                 this should not be a problem.
+
+                 The -M option does not work when input is read line  by  line
+                 (see --line-buffered.)
+
+       -m number, --max-count=number
+                 Stop  processing after finding number matching lines, or non-
+                 matching lines if -v is also set. Any trailing context  lines
+                 are  output  after  the  final match. In multiline mode, each
+                 multiline match counts as just one line for this purpose.  If
+                 this  limit is reached when reading the standard input from a
+                 regular file, the file is left positioned just after the last
+                 matching line.  If -c is also set, the count that  is  output
+                 is  never  greater  than number. This option has no effect if
+                 used with -L, -l, or -q, or when just checking for a match in
+                 a binary file.
+
+       --match-limit=number
+                 Processing some regular expression patterns may take  a  very
+                 long time to search for all possible matching strings. Others
+                 may  require  a  very large amount of memory. There are three
+                 options that set resource limits for matching.
+
+                 The --match-limit option provides a means of limiting comput-
+                 ing resource usage when processing patterns that are not  go-
+                 ing to match, but which have a very large number of possibil-
+                 ities in their search trees. The classic example is a pattern
+                 that  uses  nested unlimited repeats. Internally, PCRE2 has a
+                 counter that is incremented each time around  its  main  pro-
+                 cessing  loop.  If the value set by --match-limit is reached,
+                 an error occurs.
+
+                 The --heap-limit option specifies, as a number  of  kibibytes
+                 (units of 1024 bytes), the maximum amount of heap memory that
+                 may be used for matching.
+
+                 The  --depth-limit  option  limits  the depth of nested back-
+                 tracking points, which indirectly limits the amount of memory
+                 that is used. The amount of memory needed for each backtrack-
+                 ing point depends on the number of capturing  parentheses  in
+                 the pattern, so the amount of memory that is used before this
+                 limit  acts  varies from pattern to pattern. This limit is of
+                 use only if it is set smaller than --match-limit.
+
+                 There are no short forms for these options. The default  lim-
+                 its  can  be  set when the PCRE2 library is compiled; if they
+                 are not specified, the defaults are very large and so  effec-
+                 tively unlimited.
+
+       --max-buffer-size=number
+                 This  limits  the  expansion  of the processing buffer, whose
+                 initial size can be set by --buffer-size. The maximum  buffer
+                 size  is  silently  forced to be no smaller than the starting
+                 buffer size.
+
+       -N newline-type, --newline=newline-type
+                 Six different conventions for indicating the ends of lines in
+                 scanned files are supported. For example:
+
+                   pcre2grep -N CRLF 'some pattern' 
+
+                 The newline type may be specified in upper, lower,  or  mixed
+                 case.  If the newline type is NUL, lines are separated by bi-
+                 nary zero characters. The other types are the  single-charac-
+                 ter  sequences  CR  (carriage  return) and LF (linefeed), the
+                 two-character sequence CRLF, an "anycrlf" type, which  recog-
+                 nizes  any  of  the preceding three types, and an "any" type,
+                 for which any Unicode line ending sequence is assumed to  end
+                 a  line.  The Unicode sequences are the three just mentioned,
+                 plus VT (vertical tab, U+000B), FF (form feed,  U+000C),  NEL
+                 (next  line,  U+0085),  LS  (line  separator, U+2028), and PS
+                 (paragraph separator, U+2029).
+
+                 When the PCRE2 library is built, a  default  line-ending  se-
+                 quence  is specified.  This is normally the standard sequence
+                 for the operating system. Unless otherwise specified by  this
+                 option, pcre2grep uses the library's default.
+
+                 This  option makes it possible to use pcre2grep to scan files
+                 that have come from other environments without having to mod-
+                 ify their line endings. If the data  that  is  being  scanned
+                 does  not  agree  with  the  convention  set  by this option,
+                 pcre2grep may behave in strange ways. Note that  this  option
+                 does  not apply to files specified by the -f, --exclude-from,
+                 or --include-from options, which are expected to use the  op-
+                 erating system's standard newline sequence.
+
+       -n, --line-number
+                 Precede each output line by its line number in the file, fol-
+                 lowed  by  a colon for matching lines or a hyphen for context
+                 lines. If the file name is also being output, it precedes the
+                 line number. When the -M option causes  a  pattern  to  match
+                 more  than  one  line, only the first is preceded by its line
+                 number. This option is forced if --line-offsets is used.
+
+       --no-group-separator
+                 Do not output a separator between groups of  lines  when  -A,
+                 -B, or -C is in use. The default is to output a line contain-
+                 ing two hyphens. See also --group-separator.
+
+       --no-jit  If  the  PCRE2 library is built with support for just-in-time
+                 compiling (which speeds up matching), pcre2grep automatically
+                 makes use of this, unless it was explicitly disabled at build
+                 time. This option can be used to disable the use  of  JIT  at
+                 run time. It is provided for testing and working around prob-
+                 lems.  It should never be needed in normal use.
+
+       -O text, --output=text
+                 When  there  is  a match, instead of outputting the line that
+                 matched, output just the text specified in this option,  fol-
+                 lowed  by an operating-system standard newline. In this mode,
+                 --colour has no effect, and no context is  shown.   That  is,
+                 the  -A, -B, and -C options are ignored. The --newline option
+                 has no effect on this option,  which  is  mutually  exclusive
+                 with  --only-matching,  --file-offsets,  and  --line-offsets.
+                 However, like --only-matching, if  there  is  more  than  one
+                 match in a line, each of them causes a line of output.
+
+                 Escape sequences starting with a dollar character may be used
+                 to insert the contents of the matched part of the line and/or
+                 captured substrings into the text.
+
+                 $  or  ${}  is  replaced by the captured sub-
+                 string of the given  decimal  number;  zero  substitutes  the
+                 whole match. If the number is greater than the number of cap-
+                 turing  substrings,  or if the capture is unset, the replace-
+                 ment is empty.
+
+                 $a is replaced by bell; $b by backspace; $e by escape; $f  by
+                 form  feed;  $n by newline; $r by carriage return; $t by tab;
+                 $v by vertical tab.
+
+                 $o or $o{} is replaced by the character whose
+                 code point is the given octal number. In the first  form,  up
+                 to  three  octal  digits are processed.  When more digits are
+                 needed in Unicode mode to specify a wide character, the  sec-
+                 ond form must be used.
+
+                 $x  or $x{} is replaced by the character rep-
+                 resented by the given hexadecimal number. In the first  form,
+                 up  to two hexadecimal digits are processed. When more digits
+                 are needed in Unicode mode to specify a wide  character,  the
+                 second form must be used.
+
+                 Any  other character is substituted by itself. In particular,
+                 $$ is replaced by a single dollar.
+
+       -o, --only-matching
+                 Show only the part of the line that matched a pattern instead
+                 of the whole line. In this mode, no context  is  shown.  That
+                 is,  the -A, -B, and -C options are ignored. If there is more
+                 than one match in a line, each of them is  shown  separately,
+                 on  a separate line of output. If -o is combined with -v (in-
+                 vert the sense of the match to find non-matching  lines),  no
+                 output  is  generated,  but  the return code is set appropri-
+                 ately. If the matched portion of the line is  empty,  nothing
+                 is  output  unless  the  file  name  or line number are being
+                 printed, in which case they are shown on an  otherwise  empty
+                 line.  This  option  is  mutually  exclusive  with  --output,
+                 --file-offsets and --line-offsets.
+
+       -onumber, --only-matching=number
+                 Show only the part of the line  that  matched  the  capturing
+                 parentheses of the given number. Up to 50 capturing parenthe-
+                 ses  are  supported by default. This limit can be changed via
+                 the --om-capture option. A pattern may contain any number  of
+                 capturing  parentheses, but only those whose number is within
+                 the limit can be accessed by -o. An error occurs if the  num-
+                 ber specified by -o is greater than the limit.
+
+                 -o0 is the same as -o without a number. Because these options
+                 can  be given without an argument (see above), if an argument
+                 is present, it must be given in the same shell item, for  ex-
+                 ample,  -o3  or --only-matching=2. The comments given for the
+                 non-argument case above also apply to  this  option.  If  the
+                 specified  capturing parentheses do not exist in the pattern,
+                 or were not set in the match, nothing is  output  unless  the
+                 file name or line number are being output.
+
+                 If  this  option is given multiple times, multiple substrings
+                 are output for each match,  in  the  order  the  options  are
+                 given,  and  all on one line. For example, -o3 -o1 -o3 causes
+                 the substrings matched by capturing parentheses 3 and  1  and
+                 then  3 again to be output. By default, there is no separator
+                 (but see the next but one option).
+
+       --om-capture=number
+                 Set the number of capturing parentheses that can be  accessed
+                 by -o. The default is 50.
+
+       --om-separator=text
+                 Specify  a  separating string for multiple occurrences of -o.
+                 The default is an empty string. Separating strings are  never
+                 coloured.
+
+       -P, --no-ucp
+                 Starting  from release 10.43, when UTF/Unicode mode is speci-
+                 fied with -u or -U, the PCRE2_UCP option is used by  default.
+                 This means that the POSIX classes in patterns match more than
+                 just  ASCII  characters.  For  example, [:digit:] matches any
+                 Unicode  decimal  digit.  The  --no-ucp   option   suppresses
+                 PCRE2_UCP,  thus restricting the POSIX classes to ASCII char-
+                 acters, as was the case in earlier releases. Note that  there
+                 are  now  more  fine-grained  option settings within patterns
+                 that affect individual classes.  For  example,  when  in  UCP
+                 mode, the sequence (?aP) restricts [:word:] to ASCII letters,
+                 while allowing \w to match Unicode letters and digits.
+
+       -q, --quiet
+                 Work quietly, that is, display nothing except error messages.
+                 The  exit  status  indicates  whether or not any matches were
+                 found.
+
+       -r, --recursive
+                 If any given path is a directory, recursively scan the  files
+                 it  contains, taking note of any --include and --exclude set-
+                 tings. By default, a directory is read as a normal  file;  in
+                 some  operating  systems this gives an immediate end-of-file.
+                 This option is a shorthand for setting the -d option to  "re-
+                 curse".
+
+       --recursion-limit=number
+                 This  is  an obsolete synonym for --depth-limit. See --match-
+                 limit above for details.
+
+       -s, --no-messages
+                 Suppress error  messages  about  non-existent  or  unreadable
+                 files.  Such  files  are quietly skipped. However, the return
+                 code is still 2, even if matches were found in other files.
+
+       -t, --total-count
+                 This option is useful when scanning more than  one  file.  If
+                 used  on its own, -t suppresses all output except for a grand
+                 total number of matching lines (or non-matching lines  if  -v
+                 is used) in all the files. If -t is used with -c, a grand to-
+                 tal  is  output  except  when the previous output is just one
+                 line. In other words, it is not output when just  one  file's
+                 count  is  listed.  If file names are being output, the grand
+                 total is preceded by "TOTAL:". Otherwise, it appears as  just
+                 another  number.  The  -t option is ignored when used with -L
+                 (list files without matches), because the grand  total  would
+                 always be zero.
+
+       -u, --utf Operate in UTF/Unicode mode. This option is available only if
+                 PCRE2 has been compiled with UTF-8 support. All patterns (in-
+                 cluding  those  for  any --exclude and --include options) and
+                 all lines that are scanned must be  valid  strings  of  UTF-8
+                 characters. If an invalid UTF-8 string is encountered, an er-
+                 ror occurs.
+
+       -U, --utf-allow-invalid
+                 As  --utf,  but in addition subject lines may contain invalid
+                 UTF-8 code unit sequences. These can never form part  of  any
+                 pattern  match.  Patterns  themselves, however, must still be
+                 valid UTF-8 strings. This facility allows valid UTF-8 strings
+                 to be sought within arbitrary byte sequences in executable or
+                 other binary files. For more details about matching  in  non-
+                 valid UTF-8 strings, see the pcre2unicode(3) documentation.
+
+       -V, --version
+                 Write  the version numbers of pcre2grep and the PCRE2 library
+                 to the standard output and then exit. Anything  else  on  the
+                 command line is ignored.
+
+       -v, --invert-match
+                 Invert  the  sense  of  the match, so that lines which do not
+                 match any of the patterns are the ones that are  found.  When
+                 this  option  is  set,  options  such  as --only-matching and
+                 --output, which specify parts of a match that are to be  out-
+                 put, are ignored.
+
+       -w, --word-regex, --word-regexp
+                 Force the patterns only to match "words". That is, there must
+                 be  a  word  boundary  at  the  start and end of each matched
+                 string. This is equivalent to having "\b(?:" at the start  of
+                 each  pattern, and ")\b" at the end. This option applies only
+                 to the patterns that are  matched  against  the  contents  of
+                 files;  it does not apply to patterns specified by any of the
+                 --include or --exclude options.
+
+       -x, --line-regex, --line-regexp
+                 Force the patterns to start matching only at  the  beginnings
+                 of  lines,  and  in  addition,  require  them to match entire
+                 lines. In multiline mode the match may be more than one line.
+                 This is equivalent to having "^(?:" at the start of each pat-
+                 tern and ")$" at the end. This option  applies  only  to  the
+                 patterns  that  are matched against the contents of files; it
+                 does not apply to patterns specified by any of the  --include
+                 or --exclude options.
+
+       -Z, --null
+                 Terminate  files names in the regular output with a zero byte
+                 (the NUL character) instead of what  would  normally  appear.
+                 This  is  useful  when  file names contain unusual characters
+                 such as colons, hyphens, or even newlines.  The  option  does
+                 not apply to file names in error messages.
+
+
+ENVIRONMENT VARIABLES
+
+       The environment variables LC_ALL and LC_CTYPE are examined, in that or-
+       der, for a locale. The first one that is set is used. This can be over-
+       ridden by the --locale option. If no locale is set, the PCRE2 library's
+       default (usually the "C" locale) is used.
+
+
+NEWLINES
+
+       The  -N  (--newline) option allows pcre2grep to scan files with newline
+       conventions that differ from the default. This option affects only  the
+       way  scanned files are processed. It does not affect the interpretation
+       of files specified by the -f,  --file-list,  --exclude-from,  or  --in-
+       clude-from options.
+
+       Any  parts  of the scanned input files that are written to the standard
+       output are copied with whatever newline sequences they have in the  in-
+       put.  However,  if  the final line of a file is output, and it does not
+       end with a newline sequence, a newline sequence is added. If  the  new-
+       line  setting  is  CR, LF, CRLF or NUL, that line ending is output; for
+       the other settings (ANYCRLF or ANY) a single NL is used.
+
+       The newline setting does not affect the way in which  pcre2grep  writes
+       newlines  in  informational  messages  to the standard output and error
+       streams.  Under Windows, the standard output is set to  be  binary,  so
+       that  "\r\n" at the ends of output lines that are copied from the input
+       is not converted to "\r\r\n" by the C I/O library. This means that  any
+       messages  written  to the standard output must end with "\r\n". For all
+       other operating systems, and for all messages  to  the  standard  error
+       stream, "\n" is used.
+
+
+OPTIONS COMPATIBILITY WITH GNU GREP
+
+       Many of the short and long forms of pcre2grep's options are the same as
+       in  the GNU grep program. Any long option of the form --xxx-regexp (GNU
+       terminology) is also  available  as  --xxx-regex  (PCRE2  terminology).
+       However,  the  --case-restrict, --depth-limit, -E, --file-list, --file-
+       offsets,   --heap-limit,   --include-dir,   --line-offsets,   --locale,
+       --match-limit,  -M,  --multiline, -N, --newline, --no-ucp, --om-separa-
+       tor, --output, -P, -u, --utf, -U, and --utf-allow-invalid  options  are
+       specific to pcre2grep, as is the use of the --only-matching option with
+       a capturing parentheses number.
+
+       Although  most  of the common options work the same way, a few are dif-
+       ferent in pcre2grep. For example, the --include option's argument is  a
+       glob for GNU grep, but in pcre2grep it is a regular expression to which
+       the  -i  option  applies.  If both the -c and -l options are given, GNU
+       grep lists only file names, without counts,  but  pcre2grep  gives  the
+       counts as well.
+
+
+OPTIONS WITH DATA
+
+       There are four different ways in which an option with data can be spec-
+       ified.   If  a  short  form option is used, the data may follow immedi-
+       ately, or (with one exception) in the next command line item. For exam-
+       ple:
+
+         -f/some/file
+         -f /some/file
+
+       The exception is the -o option, which may appear with or without  data.
+       Because  of this, if data is present, it must follow immediately in the
+       same item, for example -o3.
+
+       If a long form option is used, the data may appear in the same  command
+       line  item,  separated by an equals character, or (with two exceptions)
+       it may appear in the next command line item. For example:
+
+         --file=/some/file
+         --file /some/file
+
+       Note, however, that if you want to supply a file name beginning with  ~
+       as  data  in a shell command, and have the shell expand ~ to a home di-
+       rectory, you must separate the file name from the option,  because  the
+       shell does not treat ~ specially unless it is at the start of an item.
+
+       The  exceptions  to the above are the --colour (or --color) and --only-
+       matching options, for which the data is optional. If one of  these  op-
+       tions  does  have  data,  it  must be given in the first form, using an
+       equals character. Otherwise pcre2grep will assume that it has no data.
+
+
+USING PCRE2'S CALLOUT FACILITY
+
+       pcre2grep has, by default, support for  calling  external  programs  or
+       scripts  or  echoing  specific strings during matching by making use of
+       PCRE2's callout facility. However, this support can  be  completely  or
+       partially  disabled  when  pcre2grep is built. You can find out whether
+       your binary has support for callouts by running it with the --help  op-
+       tion.  If  callout support is completely disabled, all callouts in pat-
+       terns are ignored by pcre2grep.  If the facility is partially disabled,
+       calling external programs is not supported, and callouts  that  request
+       it are ignored.
+
+       A  callout  in a PCRE2 pattern is of the form (?C) where the argu-
+       ment is either a number or a quoted string (see the pcre2callout  docu-
+       mentation  for  details).  Numbered  callouts are ignored by pcre2grep;
+       only callouts with string arguments are useful.
+
+   Echoing a specific string
+
+       Starting the callout string with a pipe character  invokes  an  echoing
+       facility that avoids calling an external program or script. This facil-
+       ity  is  always  available,  provided that callouts were not completely
+       disabled when pcre2grep was built. The rest of the  callout  string  is
+       processed  as  a zero-terminated string, which means it should not con-
+       tain any internal binary zeros. It is written  to  the  output,  having
+       first  been  passed through the same escape processing as text from the
+       --output (-O) option (see above). However, $0 cannot be used to  insert
+       a  matched  substring  because the match is still in progress. Instead,
+       the single character '0' is inserted. Any syntax errors in  the  string
+       (for  example,  a  dollar not followed by another character) causes the
+       callout to be ignored. No terminator is added to the output string,  so
+       if  you want a newline, you must include it explicitly using the escape
+       $n. For example:
+
+         pcre2grep '(.)(..(.))(?C"|[$1] [$2] [$3]$n")' 
+
+       Matching continues normally after the string is output. If you want  to
+       see  only  the  callout output but not any output from an actual match,
+       you should end the pattern with (*FAIL).
+
+   Calling external programs or scripts
+
+       This facility can be independently disabled when pcre2grep is built. It
+       is supported for Windows, where a call to _spawnvp() is used, for  VMS,
+       where  lib$spawn()  is  used,  and  for any Unix-like environment where
+       fork() and execv() are available.
+
+       If the callout string does not start with a pipe (vertical bar) charac-
+       ter, it is parsed into a list of substrings separated by  pipe  charac-
+       ters.  The first substring must be an executable name, with the follow-
+       ing substrings specifying arguments:
+
+         executable_name|arg1|arg2|...
+
+       Any substring (including the executable name) may  contain  escape  se-
+       quences  started  by  a dollar character. These are the same as for the
+       --output (-O) option documented above, except that $0 cannot insert the
+       matched string because the match is still  in  progress.  Instead,  the
+       character '0' is inserted. If you need a literal dollar or pipe charac-
+       ter in any substring, use $$ or $| respectively. Here is an example:
+
+         echo -e "abcde\n12345" | pcre2grep \
+           '(?x)(.)(..(.))
+           (?C"/bin/echo|Arg1: [$1] [$2] [$3]|Arg2: $|${1}$| ($4)")()' -
+
+         Output:
+
+           Arg1: [a] [bcd] [d] Arg2: |a| ()
+           abcde
+           Arg1: [1] [234] [4] Arg2: |1| ()
+           12345
+
+       The  parameters  for the system call that is used to run the program or
+       script are zero-terminated strings. This means that binary zero charac-
+       ters in the callout argument will cause premature termination of  their
+       substrings,  and  therefore should not be present. Any syntax errors in
+       the string (for example, a dollar not followed  by  another  character)
+       causes the callout to be ignored.  If running the program fails for any
+       reason  (including the non-existence of the executable), a local match-
+       ing failure occurs and the matcher backtracks in the normal way.
+
+
+MATCHING ERRORS
+
+       It is possible to supply a regular expression that takes  a  very  long
+       time  to  fail  to  match certain lines. Such patterns normally involve
+       nested indefinite repeats, for example: (a+)*\d when matched against  a
+       line  of a's with no final digit. The PCRE2 matching function has a re-
+       source limit that causes it to abort in these  circumstances.  If  this
+       happens,  pcre2grep  outputs  an error message and the line that caused
+       the problem to the standard error stream. If there  are  more  than  20
+       such errors, pcre2grep gives up.
+
+       The  --match-limit  option  of pcre2grep can be used to set the overall
+       resource limit. There are also other limits that affect the  amount  of
+       memory  used  during  matching;  see the discussion of --heap-limit and
+       --depth-limit above.
+
+
+DIAGNOSTICS
+
+       Exit status is 0 if any matches were found, 1 if no matches were found,
+       and 2 for syntax errors, overlong lines, non-existent  or  inaccessible
+       files  (even if matches were found in other files) or too many matching
+       errors. Using the -s option to suppress error messages about inaccessi-
+       ble files does not affect the return code.
+
+       When  run  under  VMS,  the  return  code  is  placed  in  the   symbol
+       PCRE2GREP_RC  because  VMS  does  not  distinguish  between exit(0) and
+       exit(1).

+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 JUST-IN-TIME COMPILER SUPPORT"
+.rs
+.sp
+Just-in-time compiling is a heavyweight optimization that can greatly speed up
+pattern matching. However, it comes at the cost of extra processing before the
+match is performed, so it is of most benefit when the same pattern is going to
+be matched many times. This does not necessarily mean many calls of a matching
+function; if the pattern is not anchored, matching attempts may take place many
+times at various positions in the subject, even for a single call. Therefore,
+if the subject string is very long, it may still pay to use JIT even for
+one-off matches. JIT support is available for all of the 8-bit, 16-bit and
+32-bit PCRE2 libraries.
+.P
+JIT support applies only to the traditional Perl-compatible matching function.
+It does not apply when the DFA matching function is being used. The code for
+JIT support was written by Zoltan Herczeg.
+.
+.
+.SH "AVAILABILITY OF JIT SUPPORT"
+.rs
+.sp
+JIT support is an optional feature of PCRE2. The "configure" option
+--enable-jit (or equivalent CMake option) must be set when PCRE2 is built if
+you want to use JIT. The support is limited to the following hardware
+platforms:
+.sp
+  ARM 32-bit (v7, and Thumb2)
+  ARM 64-bit
+  IBM s390x 64 bit
+  Intel x86 32-bit and 64-bit
+  LoongArch 64 bit
+  MIPS 32-bit and 64-bit
+  Power PC 32-bit and 64-bit
+  RISC-V 32-bit and 64-bit
+.sp
+If --enable-jit is set on an unsupported platform, compilation fails.
+.P
+A client program can tell if JIT support is available by calling
+\fBpcre2_config()\fP with the PCRE2_CONFIG_JIT option. The result is one if
+PCRE2 was built with JIT support, and zero otherwise. However, having the JIT
+code available does not guarantee that it will be used for any particular
+match. One reason for this is that there are a number of options and pattern
+items that are
+.\" HTML 
+.\" 
+not supported by JIT
+.\"
+(see below). Another reason is that in some environments JIT is unable to get
+memory in which to build its compiled code. The only guarantee from
+\fBpcre2_config()\fP is that if it returns zero, JIT will definitely \fInot\fP
+be used.
+.P
+A simple program does not need to check availability in order to use JIT when
+possible. The API is implemented in a way that falls back to the interpretive
+code if JIT is not available or cannot be used for a given match. For programs
+that need the best possible performance, there is a
+.\" HTML 
+.\" 
+"fast path"
+.\"
+API that is JIT-specific.
+.
+.
+.SH "SIMPLE USE OF JIT"
+.rs
+.sp
+To make use of the JIT support in the simplest way, all you have to do is to
+call \fBpcre2_jit_compile()\fP after successfully compiling a pattern with
+\fBpcre2_compile()\fP. This function has two arguments: the first is the
+compiled pattern pointer that was returned by \fBpcre2_compile()\fP, and the
+second is zero or more of the following option bits: PCRE2_JIT_COMPLETE,
+PCRE2_JIT_PARTIAL_HARD, or PCRE2_JIT_PARTIAL_SOFT.
+.P
+If JIT support is not available, a call to \fBpcre2_jit_compile()\fP does
+nothing and returns PCRE2_ERROR_JIT_BADOPTION. Otherwise, the compiled pattern
+is passed to the JIT compiler, which turns it into machine code that executes
+much faster than the normal interpretive code, but yields exactly the same
+results. The returned value from \fBpcre2_jit_compile()\fP is zero on success,
+or a negative error code.
+.P
+There is a limit to the size of pattern that JIT supports, imposed by the size
+of machine stack that it uses. The exact rules are not documented because they
+may change at any time, in particular, when new optimizations are introduced.
+If a pattern is too big, a call to \fBpcre2_jit_compile()\fP returns
+PCRE2_ERROR_NOMEMORY.
+.P
+PCRE2_JIT_COMPLETE requests the JIT compiler to generate code for complete
+matches. If you want to run partial matches using the PCRE2_PARTIAL_HARD or
+PCRE2_PARTIAL_SOFT options of \fBpcre2_match()\fP, you should set one or both
+of the other options as well as, or instead of PCRE2_JIT_COMPLETE. The JIT
+compiler generates different optimized code for each of the three modes
+(normal, soft partial, hard partial). When \fBpcre2_match()\fP is called, the
+appropriate code is run if it is available. Otherwise, the pattern is matched
+using interpretive code.
+.P
+You can call \fBpcre2_jit_compile()\fP multiple times for the same compiled
+pattern. It does nothing if it has previously compiled code for any of the
+option bits. For example, you can call it once with PCRE2_JIT_COMPLETE and
+(perhaps later, when you find you need partial matching) again with
+PCRE2_JIT_COMPLETE and PCRE2_JIT_PARTIAL_HARD. This time it will ignore
+PCRE2_JIT_COMPLETE and just compile code for partial matching. If
+\fBpcre2_jit_compile()\fP is called with no option bits set, it immediately
+returns zero. This is an alternative way of testing whether JIT is available.
+.P
+At present, it is not possible to free JIT compiled code except when the entire
+compiled pattern is freed by calling \fBpcre2_code_free()\fP.
+.P
+In some circumstances you may need to call additional functions. These are
+described in the section entitled
+.\" HTML 
+.\" 
+"Controlling the JIT stack"
+.\"
+below.
+.P
+There are some \fBpcre2_match()\fP options that are not supported by JIT, and
+there are also some pattern items that JIT cannot handle. Details are given
+.\" HTML 
+.\" 
+below.
+.\"
+In both cases, matching automatically falls back to the interpretive code. If
+you want to know whether JIT was actually used for a particular match, you
+should arrange for a JIT callback function to be set up as described in the
+section entitled
+.\" HTML 
+.\" 
+"Controlling the JIT stack"
+.\"
+below, even if you do not need to supply a non-default JIT stack. Such a
+callback function is called whenever JIT code is about to be obeyed. If the
+match-time options are not right for JIT execution, the callback function is
+not obeyed.
+.P
+If the JIT compiler finds an unsupported item, no JIT data is generated. You
+can find out if JIT compilation was successful for a compiled pattern by
+calling \fBpcre2_pattern_info()\fP with the PCRE2_INFO_JITSIZE option. A
+non-zero result means that JIT compilation was successful. A result of 0 means
+that JIT support is not available, or the pattern was not processed by
+\fBpcre2_jit_compile()\fP, or the JIT compiler was not able to handle the
+pattern. Successful JIT compilation does not, however, guarantee the use of JIT
+at match time because there are some match time options that are not supported
+by JIT.
+.
+.
+.SH "MATCHING SUBJECTS CONTAINING INVALID UTF"
+.rs
+.sp
+When a pattern is compiled with the PCRE2_UTF option, subject strings are
+normally expected to be a valid sequence of UTF code units. By default, this is
+checked at the start of matching and an error is generated if invalid UTF is
+detected. The PCRE2_NO_UTF_CHECK option can be passed to \fBpcre2_match()\fP to
+skip the check (for improved performance) if you are sure that a subject string
+is valid. If this option is used with an invalid string, the result is
+undefined. The calling program may crash or loop or otherwise misbehave.
+.P
+However, a way of running matches on strings that may contain invalid UTF
+sequences is available. Calling \fBpcre2_compile()\fP with the
+PCRE2_MATCH_INVALID_UTF option has two effects: it tells the interpreter in
+\fBpcre2_match()\fP to support invalid UTF, and, if \fBpcre2_jit_compile()\fP
+is subsequently called, the compiled JIT code also supports invalid UTF.
+Details of how this support works, in both the JIT and the interpretive cases,
+is given in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+documentation.
+.P
+There is also an obsolete option for \fBpcre2_jit_compile()\fP called
+PCRE2_JIT_INVALID_UTF, which currently exists only for backward compatibility.
+It is superseded by the \fBpcre2_compile()\fP option PCRE2_MATCH_INVALID_UTF
+and should no longer be used. It may be removed in future.
+.
+.
+.\" HTML 
+.SH "UNSUPPORTED OPTIONS AND PATTERN ITEMS"
+.rs
+.sp
+The \fBpcre2_match()\fP options that are supported for JIT matching are
+PCRE2_COPY_MATCHED_SUBJECT, PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY,
+PCRE2_NOTEMPTY_ATSTART, PCRE2_NO_UTF_CHECK, PCRE2_PARTIAL_HARD, and
+PCRE2_PARTIAL_SOFT. The PCRE2_ANCHORED and PCRE2_ENDANCHORED options are not
+supported at match time.
+.P
+If the PCRE2_NO_JIT option is passed to \fBpcre2_match()\fP it disables the
+use of JIT, forcing matching by the interpreter code.
+.P
+The only unsupported pattern items are \eC (match a single data unit) when
+running in a UTF mode, and a callout immediately before an assertion condition
+in a conditional group.
+.
+.
+.SH "RETURN VALUES FROM JIT MATCHING"
+.rs
+.sp
+When a pattern is matched using JIT, the return values are the same as those
+given by the interpretive \fBpcre2_match()\fP code, with the addition of one
+new error code: PCRE2_ERROR_JIT_STACKLIMIT. This means that the memory used for
+the JIT stack was insufficient. See
+.\" HTML 
+.\" 
+"Controlling the JIT stack"
+.\"
+below for a discussion of JIT stack usage.
+.P
+The error code PCRE2_ERROR_MATCHLIMIT is returned by the JIT code if searching
+a very large pattern tree goes on for too long, as it is in the same
+circumstance when JIT is not used, but the details of exactly what is counted
+are not the same. The PCRE2_ERROR_DEPTHLIMIT error code is never returned
+when JIT matching is used.
+.
+.
+.\" HTML 
+.SH "CONTROLLING THE JIT STACK"
+.rs
+.sp
+When the compiled JIT code runs, it needs a block of memory to use as a stack.
+By default, it uses 32KiB on the machine stack. However, some large or
+complicated patterns need more than this. The error PCRE2_ERROR_JIT_STACKLIMIT
+is given when there is not enough stack. Three functions are provided for
+managing blocks of memory for use as JIT stacks. There is further discussion
+about the use of JIT stacks in the section entitled
+.\" HTML 
+.\" 
+"JIT stack FAQ"
+.\"
+below.
+.P
+The \fBpcre2_jit_stack_create()\fP function creates a JIT stack. Its arguments
+are a starting size, a maximum size, and a general context (for memory
+allocation functions, or NULL for standard memory allocation). It returns a
+pointer to an opaque structure of type \fBpcre2_jit_stack\fP, or NULL if there
+is an error. The \fBpcre2_jit_stack_free()\fP function is used to free a stack
+that is no longer needed. If its argument is NULL, this function returns
+immediately, without doing anything. (For the technically minded: the address
+space is allocated by mmap or VirtualAlloc.) A maximum stack size of 512KiB to
+1MiB should be more than enough for any pattern.
+.P
+The \fBpcre2_jit_stack_assign()\fP function specifies which stack JIT code
+should use. Its arguments are as follows:
+.sp
+  pcre2_match_context  *mcontext
+  pcre2_jit_callback    callback
+  void                 *data
+.sp
+The first argument is a pointer to a match context. When this is subsequently
+passed to a matching function, its information determines which JIT stack is
+used. If this argument is NULL, the function returns immediately, without doing
+anything. There are three cases for the values of the other two options:
+.sp
+  (1) If \fIcallback\fP is NULL and \fIdata\fP is NULL, an internal 32KiB block
+      on the machine stack is used. This is the default when a match
+      context is created.
+.sp
+  (2) If \fIcallback\fP is NULL and \fIdata\fP is not NULL, \fIdata\fP must be
+      a pointer to a valid JIT stack, the result of calling
+      \fBpcre2_jit_stack_create()\fP.
+.sp
+  (3) If \fIcallback\fP is not NULL, it must point to a function that is
+      called with \fIdata\fP as an argument at the start of matching, in
+      order to set up a JIT stack. If the return from the callback
+      function is NULL, the internal 32KiB stack is used; otherwise the
+      return value must be a valid JIT stack, the result of calling
+      \fBpcre2_jit_stack_create()\fP.
+.sp
+A callback function is obeyed whenever JIT code is about to be run; it is not
+obeyed when \fBpcre2_match()\fP is called with options that are incompatible
+for JIT matching. A callback function can therefore be used to determine
+whether a match operation was executed by JIT or by the interpreter.
+.P
+You may safely use the same JIT stack for more than one pattern (either by
+assigning directly or by callback), as long as the patterns are matched
+sequentially in the same thread. Currently, the only way to set up
+non-sequential matches in one thread is to use callouts: if a callout function
+starts another match, that match must use a different JIT stack to the one used
+for currently suspended match(es).
+.P
+In a multithread application, if you do not specify a JIT stack, or if you
+assign or pass back NULL from a callback, that is thread-safe, because each
+thread has its own machine stack. However, if you assign or pass back a
+non-NULL JIT stack, this must be a different stack for each thread so that the
+application is thread-safe.
+.P
+Strictly speaking, even more is allowed. You can assign the same non-NULL stack
+to a match context that is used by any number of patterns, as long as they are
+not used for matching by multiple threads at the same time. For example, you
+could use the same stack in all compiled patterns, with a global mutex in the
+callback to wait until the stack is available for use. However, this is an
+inefficient solution, and not recommended.
+.P
+This is a suggestion for how a multithreaded program that needs to set up
+non-default JIT stacks might operate:
+.sp
+  During thread initialization
+    thread_local_var = pcre2_jit_stack_create(...)
+.sp
+  During thread exit
+    pcre2_jit_stack_free(thread_local_var)
+.sp
+  Use a one-line callback function
+    return thread_local_var
+.sp
+All the functions described in this section do nothing if JIT is not available.
+.
+.
+.\" HTML 
+.SH "JIT STACK FAQ"
+.rs
+.sp
+(1) Why do we need JIT stacks?
+.sp
+PCRE2 (and JIT) is a recursive, depth-first engine, so it needs a stack where
+the local data of the current node is pushed before checking its child nodes.
+Allocating real machine stack on some platforms is difficult. For example, the
+stack chain needs to be updated every time if we extend the stack on PowerPC.
+Although it is possible, its updating time overhead decreases performance. So
+we do the recursion in memory.
+.P
+(2) Why don't we simply allocate blocks of memory with \fBmalloc()\fP?
+.sp
+Modern operating systems have a nice feature: they can reserve an address space
+instead of allocating memory. We can safely allocate memory pages inside this
+address space, so the stack could grow without moving memory data (this is
+important because of pointers). Thus we can allocate 1MiB address space, and
+use only a single memory page (usually 4KiB) if that is enough. However, we can
+still grow up to 1MiB anytime if needed.
+.P
+(3) Who "owns" a JIT stack?
+.sp
+The owner of the stack is the user program, not the JIT studied pattern or
+anything else. The user program must ensure that if a stack is being used by
+\fBpcre2_match()\fP, (that is, it is assigned to a match context that is passed
+to the pattern currently running), that stack must not be used by any other
+threads (to avoid overwriting the same memory area). The best practice for
+multithreaded programs is to allocate a stack for each thread, and return this
+stack through the JIT callback function.
+.P
+(4) When should a JIT stack be freed?
+.sp
+You can free a JIT stack at any time, as long as it will not be used by
+\fBpcre2_match()\fP again. When you assign the stack to a match context, only a
+pointer is set. There is no reference counting or any other magic. You can free
+compiled patterns, contexts, and stacks in any order, anytime.
+Just \fIdo not\fP call \fBpcre2_match()\fP with a match context pointing to an
+already freed stack, as that will cause SEGFAULT. (Also, do not free a stack
+currently used by \fBpcre2_match()\fP in another thread). You can also replace
+the stack in a context at any time when it is not in use. You should free the
+previous stack before assigning a replacement.
+.P
+(5) Should I allocate/free a stack every time before/after calling
+\fBpcre2_match()\fP?
+.sp
+No, because this is too costly in terms of resources. However, you could
+implement some clever idea which release the stack if it is not used in let's
+say two minutes. The JIT callback can help to achieve this without keeping a
+list of patterns.
+.P
+(6) OK, the stack is for long term memory allocation. But what happens if a
+pattern causes stack overflow with a stack of 1MiB? Is that 1MiB kept until the
+stack is freed?
+.sp
+Especially on embedded systems, it might be a good idea to release memory
+sometimes without freeing the stack. There is no API for this at the moment.
+Probably a function call which returns with the currently allocated memory for
+any stack and another which allows releasing memory (shrinking the stack) would
+be a good idea if someone needs this.
+.P
+(7) This is too much of a headache. Isn't there any better solution for JIT
+stack handling?
+.sp
+No, thanks to Windows. If POSIX threads were used everywhere, we could throw
+out this complicated API.
+.
+.
+.SH "FREEING JIT SPECULATIVE MEMORY"
+.rs
+.sp
+.nf
+.B void pcre2_jit_free_unused_memory(pcre2_general_context *\fIgcontext\fP);
+.fi
+.P
+The JIT executable allocator does not free all memory when it is possible. It
+expects new allocations, and keeps some free memory around to improve
+allocation speed. However, in low memory conditions, it might be better to free
+all possible memory. You can cause this to happen by calling
+pcre2_jit_free_unused_memory(). Its argument is a general context, for custom
+memory management, or NULL for standard memory management.
+.
+.

+.SH "JIT FAST PATH API"
+.rs
+.sp
+Because the API described above falls back to interpreted matching when JIT is
+not available, it is convenient for programs that are written for general use
+in many environments. However, calling JIT via \fBpcre2_match()\fP does have a
+performance impact. Programs that are written for use where JIT is known to be
+available, and which need the best possible performance, can instead use a
+"fast path" API to call JIT matching directly instead of calling
+\fBpcre2_match()\fP (obviously only for patterns that have been successfully
+processed by \fBpcre2_jit_compile()\fP).
+.P
+The fast path function is called \fBpcre2_jit_match()\fP, and it takes exactly
+the same arguments as \fBpcre2_match()\fP. However, the subject string must be
+specified with a length; PCRE2_ZERO_TERMINATED is not supported. Unsupported
+option bits (for example, PCRE2_ANCHORED and PCRE2_ENDANCHORED) are ignored, as
+is the PCRE2_NO_JIT option. The return values are also the same as for
+\fBpcre2_match()\fP, plus PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial
+or complete) is requested that was not compiled.
+.P
+When you call \fBpcre2_match()\fP, as well as testing for invalid options, a
+number of other sanity checks are performed on the arguments. For example, if
+the subject pointer is NULL but the length is non-zero, an immediate error is
+given. Also, unless PCRE2_NO_UTF_CHECK is set, a UTF subject string is tested
+for validity. In the interests of speed, these checks do not happen on the JIT
+fast path. If invalid UTF data is passed when PCRE2_MATCH_INVALID_UTF was not
+set for \fBpcre2_compile()\fP, the result is undefined. The program may crash
+or loop or give wrong results. In the absence of PCRE2_MATCH_INVALID_UTF you
+should call \fBpcre2_jit_match()\fP in UTF mode only if you are sure the
+subject is valid.
+.P
+Bypassing the sanity checks and the \fBpcre2_match()\fP wrapping can give
+speedups of more than 10%.

+.TH PCRE2LIMITS 3 "1 August 2023" "PCRE2 10.43"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "SIZE AND OTHER LIMITATIONS"
+.rs
+.sp
+There are some size limitations in PCRE2 but it is hoped that they will never
+in practice be relevant.
+.P
+The maximum size of a compiled pattern is approximately 64 thousand code units
+for the 8-bit and 16-bit libraries if PCRE2 is compiled with the default
+internal linkage size, which is 2 bytes for these libraries. If you want to
+process regular expressions that are truly enormous, you can compile PCRE2 with
+an internal linkage size of 3 or 4 (when building the 16-bit library, 3 is
+rounded up to 4). See the \fBREADME\fP file in the source distribution and the
+.\" HREF
+\fBpcre2build\fP
+.\"
+documentation for details. In these cases the limit is substantially larger.
+However, the speed of execution is slower. In the 32-bit library, the internal
+linkage size is always 4.
+.P
+The maximum length of a source pattern string is essentially unlimited; it is
+the largest number a PCRE2_SIZE variable can hold. However, the program that
+calls \fBpcre2_compile()\fP can specify a smaller limit.
+.P
+The maximum length (in code units) of a subject string is one less than the
+largest number a PCRE2_SIZE variable can hold. PCRE2_SIZE is an unsigned
+integer type, usually defined as size_t. Its maximum value (that is
+~(PCRE2_SIZE)0) is reserved as a special indicator for zero-terminated strings
+and unset offsets.
+.P
+All values in repeating quantifiers must be less than 65536.
+.P
+There are two different limits that apply to branches of lookbehind assertions.
+If every branch in such an assertion matches a fixed number of characters,
+the maximum length of any branch is 65535 characters. If any branch matches a
+variable number of characters, then the maximum matching length for every
+branch is limited. The default limit is set at compile time, defaulting to 255,
+but can be changed by the calling program.
+.P
+There is no limit to the number of parenthesized groups, but there can be no
+more than 65535 capture groups, and there is a limit to the depth of nesting of
+parenthesized subpatterns of all kinds. This is imposed in order to limit the
+amount of system stack used at compile time. The default limit can be specified
+when PCRE2 is built; if not, the default is set to 250. An application can
+change this limit by calling pcre2_set_parens_nest_limit() to set the limit in
+a compile context.
+.P
+The maximum length of name for a named capture group is 32 code units, and the
+maximum number of such groups is 10000.
+.P
+The maximum length of a name in a (*MARK), (*PRUNE), (*SKIP), or (*THEN) verb
+is 255 code units for the 8-bit library and 65535 code units for the 16-bit and
+32-bit libraries.
+.P
+The maximum length of a string argument to a callout is the largest number a
+32-bit unsigned integer can hold.
+.P
+The maximum amount of heap memory used for matching is controlled by the heap
+limit, which can be set in a pattern or in a match context. The default is a
+very large number, effectively unlimited.

+.TH PCRE2MATCHING 3 "19 January 2024" "PCRE2 10.43"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 MATCHING ALGORITHMS"
+.rs
+.sp
+This document describes the two different algorithms that are available in
+PCRE2 for matching a compiled regular expression against a given subject
+string. The "standard" algorithm is the one provided by the \fBpcre2_match()\fP
+function. This works in the same as Perl's matching function, and provide a
+Perl-compatible matching operation. The just-in-time (JIT) optimization that is
+described in the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation is compatible with this function.
+.P
+An alternative algorithm is provided by the \fBpcre2_dfa_match()\fP function;
+it operates in a different way, and is not Perl-compatible. This alternative
+has advantages and disadvantages compared with the standard algorithm, and
+these are described below.
+.P
+When there is only one possible way in which a given subject string can match a
+pattern, the two algorithms give the same answer. A difference arises, however,
+when there are multiple possibilities. For example, if the pattern
+.sp
+  ^<.*>
+.sp
+is matched against the string
+.sp
+    
+.sp
+there are three possible answers. The standard algorithm finds only one of
+them, whereas the alternative algorithm finds all three.
+.
+.
+.SH "REGULAR EXPRESSIONS AS TREES"
+.rs
+.sp
+The set of strings that are matched by a regular expression can be represented
+as a tree structure. An unlimited repetition in the pattern makes the tree of
+infinite size, but it is still a tree. Matching the pattern to a given subject
+string (from a given starting point) can be thought of as a search of the tree.
+There are two ways to search a tree: depth-first and breadth-first, and these
+correspond to the two matching algorithms provided by PCRE2.
+.
+.
+.SH "THE STANDARD MATCHING ALGORITHM"
+.rs
+.sp
+In the terminology of Jeffrey Friedl's book "Mastering Regular Expressions",
+the standard algorithm is an "NFA algorithm". It conducts a depth-first search
+of the pattern tree. That is, it proceeds along a single path through the tree,
+checking that the subject matches what is required. When there is a mismatch,
+the algorithm tries any alternatives at the current point, and if they all
+fail, it backs up to the previous branch point in the tree, and tries the next
+alternative branch at that level. This often involves backing up (moving to the
+left) in the subject string as well. The order in which repetition branches are
+tried is controlled by the greedy or ungreedy nature of the quantifier.
+.P
+If a leaf node is reached, a matching string has been found, and at that point
+the algorithm stops. Thus, if there is more than one possible match, this
+algorithm returns the first one that it finds. Whether this is the shortest,
+the longest, or some intermediate length depends on the way the alternations
+and the greedy or ungreedy repetition quantifiers are specified in the
+pattern.
+.P
+Because it ends up with a single path through the tree, it is relatively
+straightforward for this algorithm to keep track of the substrings that are
+matched by portions of the pattern in parentheses. This provides support for
+capturing parentheses and backreferences.
+.
+.
+.SH "THE ALTERNATIVE MATCHING ALGORITHM"
+.rs
+.sp
+This algorithm conducts a breadth-first search of the tree. Starting from the
+first matching point in the subject, it scans the subject string from left to
+right, once, character by character, and as it does this, it remembers all the
+paths through the tree that represent valid matches. In Friedl's terminology,
+this is a kind of "DFA algorithm", though it is not implemented as a
+traditional finite state machine (it keeps multiple states active
+simultaneously).
+.P
+Although the general principle of this matching algorithm is that it scans the
+subject string only once, without backtracking, there is one exception: when a
+lookaround assertion is encountered, the characters following or preceding the
+current point have to be independently inspected.
+.P
+The scan continues until either the end of the subject is reached, or there are
+no more unterminated paths. At this point, terminated paths represent the
+different matching possibilities (if there are none, the match has failed).
+Thus, if there is more than one possible match, this algorithm finds all of
+them, and in particular, it finds the longest. The matches are returned in
+the output vector in decreasing order of length. There is an option to stop the
+algorithm after the first match (which is necessarily the shortest) is found.
+.P
+Note that the size of vector needed to contain all the results depends on the
+number of simultaneous matches, not on the number of parentheses in the
+pattern. Using \fBpcre2_match_data_create_from_pattern()\fP to create the match
+data block is therefore not advisable when doing DFA matching.
+.P
+Note also that all the matches that are found start at the same point in the
+subject. If the pattern
+.sp
+  cat(er(pillar)?)?
+.sp
+is matched against the string "the caterpillar catchment", the result is the
+three strings "caterpillar", "cater", and "cat" that start at the fifth
+character of the subject. The algorithm does not automatically move on to find
+matches that start at later positions.
+.P
+PCRE2's "auto-possessification" optimization usually applies to character
+repeats at the end of a pattern (as well as internally). For example, the
+pattern "a\ed+" is compiled as if it were "a\ed++" because there is no point
+even considering the possibility of backtracking into the repeated digits. For
+DFA matching, this means that only one possible match is found. If you really
+do want multiple matches in such cases, either use an ungreedy repeat
+("a\ed+?") or set the PCRE2_NO_AUTO_POSSESS option when compiling.
+.P
+There are a number of features of PCRE2 regular expressions that are not
+supported or behave differently in the alternative matching function. Those
+that are not supported cause an error if encountered.
+.P
+1. Because the algorithm finds all possible matches, the greedy or ungreedy
+nature of repetition quantifiers is not relevant (though it may affect
+auto-possessification, as just described). During matching, greedy and ungreedy
+quantifiers are treated in exactly the same way. However, possessive
+quantifiers can make a difference when what follows could also match what is
+quantified, for example in a pattern like this:
+.sp
+  ^a++\ew!
+.sp
+This pattern matches "aaab!" but not "aaa!", which would be matched by a
+non-possessive quantifier. Similarly, if an atomic group is present, it is
+matched as if it were a standalone pattern at the current point, and the
+longest match is then "locked in" for the rest of the overall pattern.
+.P
+2. When dealing with multiple paths through the tree simultaneously, it is not
+straightforward to keep track of captured substrings for the different matching
+possibilities, and PCRE2's implementation of this algorithm does not attempt to
+do this. This means that no captured substrings are available.
+.P
+3. Because no substrings are captured, backreferences within the pattern are
+not supported.
+.P
+4. For the same reason, conditional expressions that use a backreference as the
+condition or test for a specific group recursion are not supported.
+.P
+5. Again for the same reason, script runs are not supported.
+.P
+6. Because many paths through the tree may be active, the \eK escape sequence,
+which resets the start of the match when encountered (but may be on some paths
+and not on others), is not supported.
+.P
+7. Callouts are supported, but the value of the \fIcapture_top\fP field is
+always 1, and the value of the \fIcapture_last\fP field is always 0.
+.P
+8. The \eC escape sequence, which (in the standard algorithm) always matches a
+single code unit, even in a UTF mode, is not supported in these modes, because
+the alternative algorithm moves through the subject string one character (not
+code unit) at a time, for all active paths through the tree.
+.P
+9. Except for (*FAIL), the backtracking control verbs such as (*PRUNE) are not
+supported. (*FAIL) is supported, and behaves like a failing negative assertion.
+.P
+10. The PCRE2_MATCH_INVALID_UTF option for \fBpcre2_compile()\fP is not
+supported by \fBpcre2_dfa_match()\fP.
+.
+.
+.SH "ADVANTAGES OF THE ALTERNATIVE ALGORITHM"
+.rs
+.sp
+The main advantage of the alternative algorithm is that all possible matches
+(at a single point in the subject) are automatically found, and in particular,
+the longest match is found. To find more than one match at the same point using
+the standard algorithm, you have to do kludgy things with callouts.
+.P
+Partial matching is possible with this algorithm, though it has some
+limitations. The
+.\" HREF
+\fBpcre2partial\fP
+.\"
+documentation gives details of partial matching and discusses multi-segment
+matching.
+.
+.
+.SH "DISADVANTAGES OF THE ALTERNATIVE ALGORITHM"
+.rs
+.sp
+The alternative algorithm suffers from a number of disadvantages:
+.P
+1. It is substantially slower than the standard algorithm. This is partly
+because it has to search for all possible matches, but is also because it is
+less susceptible to optimization.
+.P
+2. Capturing parentheses, backreferences, script runs, and matching within
+invalid UTF string are not supported.
+.P
+3. Although atomic groups are supported, their use does not provide the
+performance advantage that it does for the standard algorithm.
+.P
+4. JIT optimization is not supported.

+.TH PCRE2PARTIAL 3 "04 September 2019" "PCRE2 10.34"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions
+.SH "PARTIAL MATCHING IN PCRE2"
+.rs
+.sp
+In normal use of PCRE2, if there is a match up to the end of a subject string,
+but more characters are needed to match the entire pattern, PCRE2_ERROR_NOMATCH
+is returned, just like any other failing match. There are circumstances where
+it might be helpful to distinguish this "partial match" case.
+.P
+One example is an application where the subject string is very long, and not
+all available at once. The requirement here is to be able to do the matching
+segment by segment, but special action is needed when a matched substring spans
+the boundary between two segments.
+.P
+Another example is checking a user input string as it is typed, to ensure that
+it conforms to a required format. Invalid characters can be immediately
+diagnosed and rejected, giving instant feedback.
+.P
+Partial matching is a PCRE2-specific feature; it is not Perl-compatible. It is
+requested by setting one of the PCRE2_PARTIAL_HARD or PCRE2_PARTIAL_SOFT
+options when calling a matching function. The difference between the two
+options is whether or not a partial match is preferred to an alternative
+complete match, though the details differ between the two types of matching
+function. If both options are set, PCRE2_PARTIAL_HARD takes precedence.
+.P
+If you want to use partial matching with just-in-time optimized code, as well
+as setting a partial match option for the matching function, you must also call
+\fBpcre2_jit_compile()\fP with one or both of these options:
+.sp
+  PCRE2_JIT_PARTIAL_HARD
+  PCRE2_JIT_PARTIAL_SOFT
+.sp
+PCRE2_JIT_COMPLETE should also be set if you are going to run non-partial
+matches on the same pattern. Separate code is compiled for each mode. If the
+appropriate JIT mode has not been compiled, interpretive matching code is used.
+.P
+Setting a partial matching option disables two of PCRE2's standard
+optimization hints. PCRE2 remembers the last literal code unit in a pattern,
+and abandons matching immediately if it is not present in the subject string.
+This optimization cannot be used for a subject string that might match only
+partially. PCRE2 also remembers a minimum length of a matching string, and does
+not bother to run the matching function on shorter strings. This optimization
+is also disabled for partial matching.
+.
+.
+.SH "REQUIREMENTS FOR A PARTIAL MATCH"
+.rs
+.sp
+A possible partial match occurs during matching when the end of the subject
+string is reached successfully, but either more characters are needed to
+complete the match, or the addition of more characters might change what is
+matched.
+.P
+Example 1: if the pattern is /abc/ and the subject is "ab", more characters are
+definitely needed to complete a match. In this case both hard and soft matching
+options yield a partial match.
+.P
+Example 2: if the pattern is /ab+/ and the subject is "ab", a complete match
+can be found, but the addition of more characters might change what is
+matched. In this case, only PCRE2_PARTIAL_HARD returns a partial match;
+PCRE2_PARTIAL_SOFT returns the complete match.
+.P
+On reaching the end of the subject, when PCRE2_PARTIAL_HARD is set, if the next
+pattern item is \ez, \eZ, \eb, \eB, or $ there is always a partial match.
+Otherwise, for both options, the next pattern item must be one that inspects a
+character, and at least one of the following must be true:
+.P
+(1) At least one character has already been inspected. An inspected character
+need not form part of the final matched string; lookbehind assertions and the
+\eK escape sequence provide ways of inspecting characters before the start of a
+matched string.
+.P
+(2) The pattern contains one or more lookbehind assertions. This condition
+exists in case there is a lookbehind that inspects characters before the start
+of the match.
+.P
+(3) There is a special case when the whole pattern can match an empty string.
+When the starting point is at the end of the subject, the empty string match is
+a possibility, and if PCRE2_PARTIAL_SOFT is set and neither of the above
+conditions is true, it is returned. However, because adding more characters
+might result in a non-empty match, PCRE2_PARTIAL_HARD returns a partial match,
+which in this case means "there is going to be a match at this point, but until
+some more characters are added, we do not know if it will be an empty string or
+something longer".
+.
+.
+.
+.SH "PARTIAL MATCHING USING pcre2_match()"
+.rs
+.sp
+When a partial matching option is set, the result of calling
+\fBpcre2_match()\fP can be one of the following:
+.TP 2
+\fBA successful match\fP
+A complete match has been found, starting and ending within this subject.
+.TP
+\fBPCRE2_ERROR_NOMATCH\fP
+No match can start anywhere in this subject.
+.TP
+\fBPCRE2_ERROR_PARTIAL\fP
+Adding more characters may result in a complete match that uses one or more
+characters from the end of this subject.
+.P
+When a partial match is returned, the first two elements in the ovector point
+to the portion of the subject that was matched, but the values in the rest of
+the ovector are undefined. The appearance of \eK in the pattern has no effect
+for a partial match. Consider this pattern:
+.sp
+  /abc\eK123/
+.sp
+If it is matched against "456abc123xyz" the result is a complete match, and the
+ovector defines the matched string as "123", because \eK resets the "start of
+match" point. However, if a partial match is requested and the subject string
+is "456abc12", a partial match is found for the string "abc12", because all
+these characters are needed for a subsequent re-match with additional
+characters.
+.P
+If there is more than one partial match, the first one that was found provides
+the data that is returned. Consider this pattern:
+.sp
+  /123\ew+X|dogY/
+.sp
+If this is matched against the subject string "abc123dog", both alternatives
+fail to match, but the end of the subject is reached during matching, so
+PCRE2_ERROR_PARTIAL is returned. The offsets are set to 3 and 9, identifying
+"123dog" as the first partial match. (In this example, there are two partial
+matches, because "dog" on its own partially matches the second alternative.)
+.
+.
+.SS "How a partial match is processed by pcre2_match()"
+.rs
+.sp
+What happens when a partial match is identified depends on which of the two
+partial matching options is set.
+.P
+If PCRE2_PARTIAL_HARD is set, PCRE2_ERROR_PARTIAL is returned as soon as a
+partial match is found, without continuing to search for possible complete
+matches. This option is "hard" because it prefers an earlier partial match over
+a later complete match. For this reason, the assumption is made that the end of
+the supplied subject string is not the true end of the available data, which is
+why \ez, \eZ, \eb, \eB, and $ always give a partial match.
+.P
+If PCRE2_PARTIAL_SOFT is set, the partial match is remembered, but matching
+continues as normal, and other alternatives in the pattern are tried. If no
+complete match can be found, PCRE2_ERROR_PARTIAL is returned instead of
+PCRE2_ERROR_NOMATCH. This option is "soft" because it prefers a complete match
+over a partial match. All the various matching items in a pattern behave as if
+the subject string is potentially complete; \ez, \eZ, and $ match at the end of
+the subject, as normal, and for \eb and \eB the end of the subject is treated
+as a non-alphanumeric.
+.P
+The difference between the two partial matching options can be illustrated by a
+pattern such as:
+.sp
+  /dog(sbody)?/
+.sp
+This matches either "dog" or "dogsbody", greedily (that is, it prefers the
+longer string if possible). If it is matched against the string "dog" with
+PCRE2_PARTIAL_SOFT, it yields a complete match for "dog". However, if
+PCRE2_PARTIAL_HARD is set, the result is PCRE2_ERROR_PARTIAL. On the other
+hand, if the pattern is made ungreedy the result is different:
+.sp
+  /dog(sbody)??/
+.sp
+In this case the result is always a complete match because that is found first,
+and matching never continues after finding a complete match. It might be easier
+to follow this explanation by thinking of the two patterns like this:
+.sp
+  /dog(sbody)?/    is the same as  /dogsbody|dog/
+  /dog(sbody)??/   is the same as  /dog|dogsbody/
+.sp
+The second pattern will never match "dogsbody", because it will always find the
+shorter match first.
+.
+.
+.SS "Example of partial matching using pcre2test"
+.rs
+.sp
+The \fBpcre2test\fP data modifiers \fBpartial_hard\fP (or \fBph\fP) and
+\fBpartial_soft\fP (or \fBps\fP) set PCRE2_PARTIAL_HARD and PCRE2_PARTIAL_SOFT,
+respectively, when calling \fBpcre2_match()\fP. Here is a run of
+\fBpcre2test\fP using a pattern that matches the whole subject in the form of a
+date:
+.sp
+    re> /^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$/
+  data> 25dec3\e=ph
+  Partial match: 23dec3
+  data> 3ju\e=ph
+  Partial match: 3ju
+  data> 3juj\e=ph
+  No match
+.sp
+This example gives the same results for both hard and soft partial matching
+options. Here is an example where there is a difference:
+.sp
+    re> /^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$/
+  data> 25jun04\e=ps
+   0: 25jun04
+   1: jun
+  data> 25jun04\e=ph
+  Partial match: 25jun04
+.sp
+With PCRE2_PARTIAL_SOFT, the subject is matched completely. For
+PCRE2_PARTIAL_HARD, however, the subject is assumed not to be complete, so
+there is only a partial match.
+.
+.
+.
+.SH "MULTI-SEGMENT MATCHING WITH pcre2_match()"
+.rs
+.sp
+PCRE was not originally designed with multi-segment matching in mind. However,
+over time, features (including partial matching) that make multi-segment
+matching possible have been added. A very long string can be searched segment
+by segment by calling \fBpcre2_match()\fP repeatedly, with the aim of achieving
+the same results that would happen if the entire string was available for
+searching all the time. Normally, the strings that are being sought are much
+shorter than each individual segment, and are in the middle of very long
+strings, so the pattern is normally not anchored.
+.P
+Special logic must be implemented to handle a matched substring that spans a
+segment boundary. PCRE2_PARTIAL_HARD should be used, because it returns a
+partial match at the end of a segment whenever there is the possibility of
+changing the match by adding more characters. The PCRE2_NOTBOL option should
+also be set for all but the first segment.
+.P
+When a partial match occurs, the next segment must be added to the current
+subject and the match re-run, using the \fIstartoffset\fP argument of
+\fBpcre2_match()\fP to begin at the point where the partial match started.
+For example:
+.sp
+    re> /\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed/
+  data> ...the date is 23ja\e=ph
+  Partial match: 23ja
+  data> ...the date is 23jan19 and on that day...\e=offset=15
+   0: 23jan19
+   1: jan
+.sp
+Note the use of the \fBoffset\fP modifier to start the new match where the
+partial match was found. In this example, the next segment was added to the one
+in which the partial match was found. This is the most straightforward
+approach, typically using a memory buffer that is twice the size of each
+segment. After a partial match, the first half of the buffer is discarded, the
+second half is moved to the start of the buffer, and a new segment is added
+before repeating the match as in the example above. After a no match, the
+entire buffer can be discarded.
+.P
+If there are memory constraints, you may want to discard text that precedes a
+partial match before adding the next segment. Unfortunately, this is not at
+present straightforward. In cases such as the above, where the pattern does not
+contain any lookbehinds, it is sufficient to retain only the partially matched
+substring. However, if the pattern contains a lookbehind assertion, characters
+that precede the start of the partial match may have been inspected during the
+matching process. When \fBpcre2test\fP displays a partial match, it indicates
+these characters with '<' if the \fBallusedtext\fP modifier is set:
+.sp
+    re> "(?<=123)abc"
+  data> xx123ab\e=ph,allusedtext
+  Partial match: 123ab
+                 <<<
+.sp
+However, the \fBallusedtext\fP modifier is not available for JIT matching,
+because JIT matching does not record the first (or last) consulted characters.
+For this reason, this information is not available via the API. It is therefore
+not possible in general to obtain the exact number of characters that must be
+retained in order to get the right match result. If you cannot retain the
+entire segment, you must find some heuristic way of choosing.
+.P
+If you know the approximate length of the matching substrings, you can use that
+to decide how much text to retain. The only lookbehind information that is
+currently available via the API is the length of the longest individual
+lookbehind in a pattern, but this can be misleading if there are nested
+lookbehinds. The value returned by calling \fBpcre2_pattern_info()\fP with the
+PCRE2_INFO_MAXLOOKBEHIND option is the maximum number of characters (not code
+units) that any individual lookbehind moves back when it is processed. A
+pattern such as "(?<=(? /^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$/
+  data> 23ja\e=dfa,ps
+  Partial match: 23ja
+  data> n05\e=dfa,dfa_restart
+   0: n05
+.sp
+The first call has "23ja" as the subject, and requests partial matching; the
+second call has "n05" as the subject for the continued (restarted) match.
+Notice that when the match is complete, only the last part is shown; PCRE2 does
+not retain the previously partially-matched string. It is up to the calling
+program to do that if it needs to. This means that, for an unanchored pattern,
+if a continued match fails, it is not possible to try again at a new starting
+point. All this facility is capable of doing is continuing with the previous
+match attempt. For example, consider this pattern:
+.sp
+  1234|3789
+.sp
+If the first part of the subject is "ABC123", a partial match of the first
+alternative is found at offset 3. There is no partial match for the second
+alternative, because such a match does not start at the same point in the
+subject string. Attempting to continue with the string "7890" does not yield a
+match because only those alternatives that match at one point in the subject
+are remembered. Depending on the application, this may or may not be what you
+want.
+.P
+If you do want to allow for starting again at the next character, one way of
+doing it is to retain some or all of the segment and try a new complete match,
+as described for \fBpcre2_match()\fP above. Another possibility is to work with
+two buffers. If a partial match at offset \fIn\fP in the first buffer is
+followed by "no match" when PCRE2_DFA_RESTART is used on the second buffer, you
+can then try a new match starting at offset \fIn+1\fP in the first buffer.

+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 REGULAR EXPRESSION DETAILS"
+.rs
+.sp
+The syntax and semantics of the regular expressions that are supported by PCRE2
+are described in detail below. There is a quick-reference syntax summary in the
+.\" HREF
+\fBpcre2syntax\fP
+.\"
+page. PCRE2 tries to match Perl syntax and semantics as closely as it can.
+PCRE2 also supports some alternative regular expression syntax (which does not
+conflict with the Perl syntax) in order to provide some compatibility with
+regular expressions in Python, .NET, and Oniguruma.
+.P
+Perl's regular expressions are described in its own documentation, and regular
+expressions in general are covered in a number of books, some of which have
+copious examples. Jeffrey Friedl's "Mastering Regular Expressions", published
+by O'Reilly, covers regular expressions in great detail. This description of
+PCRE2's regular expressions is intended as reference material.
+.P
+This document discusses the regular expression patterns that are supported by
+PCRE2 when its main matching function, \fBpcre2_match()\fP, is used. PCRE2 also
+has an alternative matching function, \fBpcre2_dfa_match()\fP, which matches
+using a different algorithm that is not Perl-compatible. Some of the features
+discussed below are not available when DFA matching is used. The advantages and
+disadvantages of the alternative function, and how it differs from the normal
+function, are discussed in the
+.\" HREF
+\fBpcre2matching\fP
+.\"
+page.
+.
+.
+.SH "SPECIAL START-OF-PATTERN ITEMS"
+.rs
+.sp
+A number of options that can be passed to \fBpcre2_compile()\fP can also be set
+by special items at the start of a pattern. These are not Perl-compatible, but
+are provided to make these options accessible to pattern writers who are not
+able to change the program that processes the pattern. Any number of these
+items may appear, but they must all be together right at the start of the
+pattern string, and the letters must be in upper case.
+.
+.
+.SS "UTF support"
+.rs
+.sp
+In the 8-bit and 16-bit PCRE2 libraries, characters may be coded either as
+single code units, or as multiple UTF-8 or UTF-16 code units. UTF-32 can be
+specified for the 32-bit library, in which case it constrains the character
+values to valid Unicode code points. To process UTF strings, PCRE2 must be
+built to include Unicode support (which is the default). When using UTF strings
+you must either call the compiling function with one or both of the PCRE2_UTF
+or PCRE2_MATCH_INVALID_UTF options, or the pattern must start with the special
+sequence (*UTF), which is equivalent to setting the relevant PCRE2_UTF. How
+setting a UTF mode affects pattern matching is mentioned in several places
+below. There is also a summary of features in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+page.
+.P
+Some applications that allow their users to supply patterns may wish to
+restrict them to non-UTF data for security reasons. If the PCRE2_NEVER_UTF
+option is passed to \fBpcre2_compile()\fP, (*UTF) is not allowed, and its
+appearance in a pattern causes an error.
+.
+.
+.SS "Unicode property support"
+.rs
+.sp
+Another special sequence that may appear at the start of a pattern is (*UCP).
+This has the same effect as setting the PCRE2_UCP option: it causes sequences
+such as \ed and \ew to use Unicode properties to determine character types,
+instead of recognizing only characters with codes less than 256 via a lookup
+table. If also causes upper/lower casing operations to use Unicode properties
+for characters with code points greater than 127, even when UTF is not set.
+These behaviours can be changed within the pattern; see the section entitled
+.\" HTML 
+.\" 
+"Internal Option Setting"
+.\"
+below.
+.P
+Some applications that allow their users to supply patterns may wish to
+restrict them for security reasons. If the PCRE2_NEVER_UCP option is passed to
+\fBpcre2_compile()\fP, (*UCP) is not allowed, and its appearance in a pattern
+causes an error.
+.
+.
+.SS "Locking out empty string matching"
+.rs
+.sp
+Starting a pattern with (*NOTEMPTY) or (*NOTEMPTY_ATSTART) has the same effect
+as passing the PCRE2_NOTEMPTY or PCRE2_NOTEMPTY_ATSTART option to whichever
+matching function is subsequently called to match the pattern. These options
+lock out the matching of empty strings, either entirely, or only at the start
+of the subject.
+.
+.
+.SS "Disabling auto-possessification"
+.rs
+.sp
+If a pattern starts with (*NO_AUTO_POSSESS), it has the same effect as setting
+the PCRE2_NO_AUTO_POSSESS option. This stops PCRE2 from making quantifiers
+possessive when what follows cannot match the repeated item. For example, by
+default a+b is treated as a++b. For more details, see the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation.
+.
+.
+.SS "Disabling start-up optimizations"
+.rs
+.sp
+If a pattern starts with (*NO_START_OPT), it has the same effect as setting the
+PCRE2_NO_START_OPTIMIZE option. This disables several optimizations for quickly
+reaching "no match" results. For more details, see the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation.
+.
+.
+.SS "Disabling automatic anchoring"
+.rs
+.sp
+If a pattern starts with (*NO_DOTSTAR_ANCHOR), it has the same effect as
+setting the PCRE2_NO_DOTSTAR_ANCHOR option. This disables optimizations that
+apply to patterns whose top-level branches all start with .* (match any number
+of arbitrary characters). For more details, see the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation.
+.
+.
+.SS "Disabling JIT compilation"
+.rs
+.sp
+If a pattern that starts with (*NO_JIT) is successfully compiled, an attempt by
+the application to apply the JIT optimization by calling
+\fBpcre2_jit_compile()\fP is ignored.
+.
+.
+.SS "Setting match resource limits"
+.rs
+.sp
+The \fBpcre2_match()\fP function contains a counter that is incremented every
+time it goes round its main loop. The caller of \fBpcre2_match()\fP can set a
+limit on this counter, which therefore limits the amount of computing resource
+used for a match. The maximum depth of nested backtracking can also be limited;
+this indirectly restricts the amount of heap memory that is used, but there is
+also an explicit memory limit that can be set.
+.P
+These facilities are provided to catch runaway matches that are provoked by
+patterns with huge matching trees. A common example is a pattern with nested
+unlimited repeats applied to a long string that does not match. When one of
+these limits is reached, \fBpcre2_match()\fP gives an error return. The limits
+can also be set by items at the start of the pattern of the form
+.sp
+  (*LIMIT_HEAP=d)
+  (*LIMIT_MATCH=d)
+  (*LIMIT_DEPTH=d)
+.sp
+where d is any number of decimal digits. However, the value of the setting must
+be less than the value set (or defaulted) by the caller of \fBpcre2_match()\fP
+for it to have any effect. In other words, the pattern writer can lower the
+limits set by the programmer, but not raise them. If there is more than one
+setting of one of these limits, the lower value is used. The heap limit is
+specified in kibibytes (units of 1024 bytes).
+.P
+Prior to release 10.30, LIMIT_DEPTH was called LIMIT_RECURSION. This name is
+still recognized for backwards compatibility.
+.P
+The heap limit applies only when the \fBpcre2_match()\fP or
+\fBpcre2_dfa_match()\fP interpreters are used for matching. It does not apply
+to JIT. The match limit is used (but in a different way) when JIT is being
+used, or when \fBpcre2_dfa_match()\fP is called, to limit computing resource
+usage by those matching functions. The depth limit is ignored by JIT but is
+relevant for DFA matching, which uses function recursion for recursions within
+the pattern and for lookaround assertions and atomic groups. In this case, the
+depth limit controls the depth of such recursion.
+.
+.
+.\" HTML 
+.SS "Newline conventions"
+.rs
+.sp
+PCRE2 supports six different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, any
+Unicode newline sequence, or the NUL character (binary zero). The
+.\" HREF
+\fBpcre2api\fP
+.\"
+page has
+.\" HTML 
+.\" 
+further discussion
+.\"
+about newlines, and shows how to set the newline convention when calling
+\fBpcre2_compile()\fP.
+.P
+It is also possible to specify a newline convention by starting a pattern
+string with one of the following sequences:
+.sp
+  (*CR)        carriage return
+  (*LF)        linefeed
+  (*CRLF)      carriage return, followed by linefeed
+  (*ANYCRLF)   any of the three above
+  (*ANY)       all Unicode newline sequences
+  (*NUL)       the NUL character (binary zero)
+.sp
+These override the default and the options given to the compiling function. For
+example, on a Unix system where LF is the default newline sequence, the pattern
+.sp
+  (*CR)a.b
+.sp
+changes the convention to CR. That pattern matches "a\enb" because LF is no
+longer a newline. If more than one of these settings is present, the last one
+is used.
+.P
+The newline convention affects where the circumflex and dollar assertions are
+true. It also affects the interpretation of the dot metacharacter when
+PCRE2_DOTALL is not set, and the behaviour of \eN when not followed by an
+opening brace. However, it does not affect what the \eR escape sequence
+matches. By default, this is any Unicode newline sequence, for Perl
+compatibility. However, this can be changed; see the next section and the
+description of \eR in the section entitled
+.\" HTML 
+.\" 
+"Newline sequences"
+.\"
+below. A change of \eR setting can be combined with a change of newline
+convention.
+.
+.
+.SS "Specifying what \eR matches"
+.rs
+.sp
+It is possible to restrict \eR to match only CR, LF, or CRLF (instead of the
+complete set of Unicode line endings) by setting the option PCRE2_BSR_ANYCRLF
+at compile time. This effect can also be achieved by starting a pattern with
+(*BSR_ANYCRLF). For completeness, (*BSR_UNICODE) is also recognized,
+corresponding to PCRE2_BSR_UNICODE.
+.
+.
+.SH "EBCDIC CHARACTER CODES"
+.rs
+.sp
+PCRE2 can be compiled to run in an environment that uses EBCDIC as its
+character code instead of ASCII or Unicode (typically a mainframe system). In
+the sections below, character code values are ASCII or Unicode; in an EBCDIC
+environment these characters may have different code values, and there are no
+code points greater than 255.
+.
+.
+.SH "CHARACTERS AND METACHARACTERS"
+.rs
+.sp
+A regular expression is a pattern that is matched against a subject string from
+left to right. Most characters stand for themselves in a pattern, and match the
+corresponding characters in the subject. As a trivial example, the pattern
+.sp
+  The quick brown fox
+.sp
+matches a portion of a subject string that is identical to itself. When
+caseless matching is specified (the PCRE2_CASELESS option or (?i) within the
+pattern), letters are matched independently of case. Note that there are two
+ASCII characters, K and S, that, in addition to their lower case ASCII
+equivalents, are case-equivalent with Unicode U+212A (Kelvin sign) and U+017F
+(long S) respectively when either PCRE2_UTF or PCRE2_UCP is set, unless the
+PCRE2_EXTRA_CASELESS_RESTRICT option is in force (either passed to
+\fBpcre2_compile()\fP or set by (?r) within the pattern).
+.P
+The power of regular expressions comes from the ability to include wild cards,
+character classes, alternatives, and repetitions in the pattern. These are
+encoded in the pattern by the use of \fImetacharacters\fP, which do not stand
+for themselves but instead are interpreted in some special way.
+.P
+There are two different sets of metacharacters: those that are recognized
+anywhere in the pattern except within square brackets, and those that are
+recognized within square brackets. Outside square brackets, the metacharacters
+are as follows:
+.sp
+  \e      general escape character with several uses
+  ^      assert start of string (or line, in multiline mode)
+  $      assert end of string (or line, in multiline mode)
+  .      match any character except newline (by default)
+  [      start character class definition
+  |      start of alternative branch
+  (      start group or control verb
+  )      end group or control verb
+  *      0 or more quantifier
+  +      1 or more quantifier; also "possessive quantifier"
+  ?      0 or 1 quantifier; also quantifier minimizer
+  {      potential start of min/max quantifier
+.sp
+Brace characters { and } are also used to enclose data for constructions such
+as \eg{2} or \ek{name}. In almost all uses of braces, space and/or horizontal
+tab characters that follow { or precede } are allowed and are ignored. In the
+case of quantifiers, they may also appear before or after the comma. The
+exception to this is \eu{...} which is an ECMAScript compatibility feature
+that is recognized only when the PCRE2_EXTRA_ALT_BSUX option is set. ECMAScript
+does not ignore such white space; it causes the item to be interpreted as
+literal.
+.P
+Part of a pattern that is in square brackets is called a "character class". In
+a character class the only metacharacters are:
+.sp
+  \e      general escape character
+  ^      negate the class, but only if the first character
+  -      indicates character range
+  [      POSIX character class (if followed by POSIX syntax)
+  ]      terminates the character class
+.sp
+If a pattern is compiled with the PCRE2_EXTENDED option, most white space in
+the pattern, other than in a character class, within a \eQ...\eE sequence, or
+between a # outside a character class and the next newline, inclusive, are
+ignored. An escaping backslash can be used to include a white space or a #
+character as part of the pattern. If the PCRE2_EXTENDED_MORE option is set, the
+same applies, but in addition unescaped space and horizontal tab characters are
+ignored inside a character class. Note: only these two characters are ignored,
+not the full set of pattern white space characters that are ignored outside a
+character class. Option settings can be changed within a pattern; see the
+section entitled
+.\" HTML 
+.\" 
+"Internal Option Setting"
+.\"
+below.
+.P
+The following sections describe the use of each of the metacharacters.
+.
+.
+.SH BACKSLASH
+.rs
+.sp
+The backslash character has several uses. Firstly, if it is followed by a
+character that is not a digit or a letter, it takes away any special meaning
+that character may have. This use of backslash as an escape character applies
+both inside and outside character classes.
+.P
+For example, if you want to match a * character, you must write \e* in the
+pattern. This escaping action applies whether or not the following character
+would otherwise be interpreted as a metacharacter, so it is always safe to
+precede a non-alphanumeric with backslash to specify that it stands for itself.
+In particular, if you want to match a backslash, you write \e\e.
+.P
+Only ASCII digits and letters have any special meaning after a backslash. All
+other characters (in particular, those whose code points are greater than 127)
+are treated as literals.
+.P
+If you want to treat all characters in a sequence as literals, you can do so by
+putting them between \eQ and \eE. Note that this includes white space even when
+the PCRE2_EXTENDED option is set so that most other white space is ignored. The
+behaviour is different from Perl in that $ and @ are handled as literals in
+\eQ...\eE sequences in PCRE2, whereas in Perl, $ and @ cause variable
+interpolation. Also, Perl does "double-quotish backslash interpolation" on any
+backslashes between \eQ and \eE which, its documentation says, "may lead to
+confusing results". PCRE2 treats a backslash between \eQ and \eE just like any
+other character. Note the following examples:
+.sp
+  Pattern            PCRE2 matches   Perl matches
+.sp
+.\" JOIN
+  \eQabc$xyz\eE        abc$xyz        abc followed by the
+                                      contents of $xyz
+  \eQabc\e$xyz\eE       abc\e$xyz       abc\e$xyz
+  \eQabc\eE\e$\eQxyz\eE   abc$xyz        abc$xyz
+  \eQA\eB\eE            A\eB            A\eB
+  \eQ\e\eE              \e              \e\eE
+.sp
+The \eQ...\eE sequence is recognized both inside and outside character classes.
+An isolated \eE that is not preceded by \eQ is ignored. If \eQ is not followed
+by \eE later in the pattern, the literal interpretation continues to the end of
+the pattern (that is, \eE is assumed at the end). If the isolated \eQ is inside
+a character class, this causes an error, because the character class is then
+not terminated by a closing square bracket.
+.
+.
+.\" HTML 
+.SS "Non-printing characters"
+.rs
+.sp
+A second use of backslash provides a way of encoding non-printing characters
+in patterns in a visible manner. There is no restriction on the appearance of
+non-printing characters in a pattern, but when a pattern is being prepared by
+text editing, it is often easier to use one of the following escape sequences
+instead of the binary character it represents. In an ASCII or Unicode
+environment, these escapes are as follows:
+.sp
+  \ea          alarm, that is, the BEL character (hex 07)
+  \ecx         "control-x", where x is a non-control ASCII character
+  \ee          escape (hex 1B)
+  \ef          form feed (hex 0C)
+  \en          linefeed (hex 0A)
+  \er          carriage return (hex 0D) (but see below)
+  \et          tab (hex 09)
+  \e0dd        character with octal code 0dd
+  \eddd        character with octal code ddd, or backreference
+  \eo{ddd..}   character with octal code ddd..
+  \exhh        character with hex code hh
+  \ex{hhh..}   character with hex code hhh..
+  \eN{U+hhh..} character with Unicode hex code point hhh..
+.sp
+By default, after \ex that is not followed by {, from zero to two hexadecimal
+digits are read (letters can be in upper or lower case). Any number of
+hexadecimal digits may appear between \ex{ and }. If a character other than a
+hexadecimal digit appears between \ex{ and }, or if there is no terminating },
+an error occurs.
+.P
+Characters whose code points are less than 256 can be defined by either of the
+two syntaxes for \ex or by an octal sequence. There is no difference in the way
+they are handled. For example, \exdc is exactly the same as \ex{dc} or \e334.
+However, using the braced versions does make such sequences easier to read.
+.P
+Support is available for some ECMAScript (aka JavaScript) escape sequences via
+two compile-time options. If PCRE2_ALT_BSUX is set, the sequence \ex followed
+by { is not recognized. Only if \ex is followed by two hexadecimal digits is it
+recognized as a character escape. Otherwise it is interpreted as a literal "x"
+character. In this mode, support for code points greater than 256 is provided
+by \eu, which must be followed by four hexadecimal digits; otherwise it is
+interpreted as a literal "u" character.
+.P
+PCRE2_EXTRA_ALT_BSUX has the same effect as PCRE2_ALT_BSUX and, in addition,
+\eu{hhh..} is recognized as the character specified by hexadecimal code point.
+There may be any number of hexadecimal digits, but unlike other places that
+also use curly brackets, spaces are not allowed and would result in the string
+being interpreted as a literal. This syntax is from ECMAScript 6.
+.P
+The \eN{U+hhh..} escape sequence is recognized only when PCRE2 is operating in
+UTF mode. Perl also uses \eN{name} to specify characters by Unicode name; PCRE2
+does not support this. Note that when \eN is not followed by an opening brace
+(curly bracket) it has an entirely different meaning, matching any character
+that is not a newline.
+.P
+There are some legacy applications where the escape sequence \er is expected to
+match a newline. If the PCRE2_EXTRA_ESCAPED_CR_IS_LF option is set, \er in a
+pattern is converted to \en so that it matches a LF (linefeed) instead of a CR
+(carriage return) character.
+.P
+An error occurs if \ec is not followed by a character whose ASCII code point
+is in the range 32 to 126. The precise effect of \ecx is as follows: if x is a
+lower case letter, it is converted to upper case. Then bit 6 of the character
+(hex 40) is inverted. Thus \ecA to \ecZ become hex 01 to hex 1A (A is 41, Z is
+5A), but \ec{ becomes hex 3B ({ is 7B), and \ec; becomes hex 7B (; is 3B). If
+the code unit following \ec has a code point less than 32 or greater than 126,
+a compile-time error occurs.
+.P
+When PCRE2 is compiled in EBCDIC mode, \eN{U+hhh..} is not supported. \ea, \ee,
+\ef, \en, \er, and \et generate the appropriate EBCDIC code values. The \ec
+escape is processed as specified for Perl in the \fBperlebcdic\fP document. The
+only characters that are allowed after \ec are A-Z, a-z, or one of @, [, \e, ],
+^, _, or ?. Any other character provokes a compile-time error. The sequence
+\ec@ encodes character code 0; after \ec the letters (in either case) encode
+characters 1-26 (hex 01 to hex 1A); [, \e, ], ^, and _ encode characters 27-31
+(hex 1B to hex 1F), and \ec? becomes either 255 (hex FF) or 95 (hex 5F).
+.P
+Thus, apart from \ec?, these escapes generate the same character code values as
+they do in an ASCII environment, though the meanings of the values mostly
+differ. For example, \ecG always generates code value 7, which is BEL in ASCII
+but DEL in EBCDIC.
+.P
+The sequence \ec? generates DEL (127, hex 7F) in an ASCII environment, but
+because 127 is not a control character in EBCDIC, Perl makes it generate the
+APC character. Unfortunately, there are several variants of EBCDIC. In most of
+them the APC character has the value 255 (hex FF), but in the one Perl calls
+POSIX-BC its value is 95 (hex 5F). If certain other characters have POSIX-BC
+values, PCRE2 makes \ec? generate 95; otherwise it generates 255.
+.P
+After \e0 up to two further octal digits are read. If there are fewer than two
+digits, just those that are present are used. Thus the sequence \e0\ex\e015
+specifies two binary zeros followed by a CR character (code value 13). Make
+sure you supply two digits after the initial zero if the pattern character that
+follows is itself an octal digit.
+.P
+The escape \eo must be followed by a sequence of octal digits, enclosed in
+braces. An error occurs if this is not the case. This escape is a recent
+addition to Perl; it provides way of specifying character code points as octal
+numbers greater than 0777, and it also allows octal numbers and backreferences
+to be unambiguously specified.
+.P
+For greater clarity and unambiguity, it is best to avoid following \e by a
+digit greater than zero. Instead, use \eo{...} or \ex{...} to specify numerical
+character code points, and \eg{...} to specify backreferences. The following
+paragraphs describe the old, ambiguous syntax.
+.P
+The handling of a backslash followed by a digit other than 0 is complicated,
+and Perl has changed over time, causing PCRE2 also to change.
+.P
+Outside a character class, PCRE2 reads the digit and any following digits as a
+decimal number. If the number is less than 10, begins with the digit 8 or 9, or
+if there are at least that many previous capture groups in the expression, the
+entire sequence is taken as a \fIbackreference\fP. A description of how this
+works is given
+.\" HTML 
+.\" 
+later,
+.\"
+following the discussion of
+.\" HTML 
+.\" 
+parenthesized groups.
+.\"
+Otherwise, up to three octal digits are read to form a character code.
+.P
+Inside a character class, PCRE2 handles \e8 and \e9 as the literal characters
+"8" and "9", and otherwise reads up to three octal digits following the
+backslash, using them to generate a data character. Any subsequent digits stand
+for themselves. For example, outside a character class:
+.sp
+  \e040   is another way of writing an ASCII space
+.\" JOIN
+  \e40    is the same, provided there are fewer than 40
+            previous capture groups
+  \e7     is always a backreference
+.\" JOIN
+  \e11    might be a backreference, or another way of
+            writing a tab
+  \e011   is always a tab
+  \e0113  is a tab followed by the character "3"
+.\" JOIN
+  \e113   might be a backreference, otherwise the
+            character with octal code 113
+.\" JOIN
+  \e377   might be a backreference, otherwise
+            the value 255 (decimal)
+  \e81    is always a backreference
+.sp
+Note that octal values of 100 or greater that are specified using this syntax
+must not be introduced by a leading zero, because no more than three octal
+digits are ever read.
+.
+.
+.SS "Constraints on character values"
+.rs
+.sp
+Characters that are specified using octal or hexadecimal numbers are
+limited to certain values, as follows:
+.sp
+  8-bit non-UTF mode    no greater than 0xff
+  16-bit non-UTF mode   no greater than 0xffff
+  32-bit non-UTF mode   no greater than 0xffffffff
+  All UTF modes         no greater than 0x10ffff and a valid code point
+.sp
+Invalid Unicode code points are all those in the range 0xd800 to 0xdfff (the
+so-called "surrogate" code points). The check for these can be disabled by the
+caller of \fBpcre2_compile()\fP by setting the option
+PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES. However, this is possible only in UTF-8
+and UTF-32 modes, because these values are not representable in UTF-16.
+.
+.
+.SS "Escape sequences in character classes"
+.rs
+.sp
+All the sequences that define a single character value can be used both inside
+and outside character classes. In addition, inside a character class, \eb is
+interpreted as the backspace character (hex 08).
+.P
+When not followed by an opening brace, \eN is not allowed in a character class.
+\eB, \eR, and \eX are not special inside a character class. Like other
+unrecognized alphabetic escape sequences, they cause an error. Outside a
+character class, these sequences have different meanings.
+.
+.
+.SS "Unsupported escape sequences"
+.rs
+.sp
+In Perl, the sequences \eF, \el, \eL, \eu, and \eU are recognized by its string
+handler and used to modify the case of following characters. By default, PCRE2
+does not support these escape sequences in patterns. However, if either of the
+PCRE2_ALT_BSUX or PCRE2_EXTRA_ALT_BSUX options is set, \eU matches a "U"
+character, and \eu can be used to define a character by code point, as
+described above.
+.
+.
+.SS "Absolute and relative backreferences"
+.rs
+.sp
+The sequence \eg followed by a signed or unsigned number, optionally enclosed
+in braces, is an absolute or relative backreference. A named backreference
+can be coded as \eg{name}. Backreferences are discussed

+.SS "Generic character types"
+.rs
+.sp
+Another use of backslash is for specifying generic character types:
+.sp
+  \ed     any decimal digit
+  \eD     any character that is not a decimal digit
+  \eh     any horizontal white space character
+  \eH     any character that is not a horizontal white space character
+  \eN     any character that is not a newline
+  \es     any white space character
+  \eS     any character that is not a white space character
+  \ev     any vertical white space character
+  \eV     any character that is not a vertical white space character
+  \ew     any "word" character
+  \eW     any "non-word" character
+.sp
+The \eN escape sequence has the same meaning as
+.\" HTML 
+.\" 
+the "." metacharacter
+.\"
+when PCRE2_DOTALL is not set, but setting PCRE2_DOTALL does not change the
+meaning of \eN. Note that when \eN is followed by an opening brace it has a
+different meaning. See the section entitled
+.\" HTML 
+.\" 
+"Non-printing characters"
+.\"
+above for details. Perl also uses \eN{name} to specify characters by Unicode
+name; PCRE2 does not support this.
+.P
+Each pair of lower and upper case escape sequences partitions the complete set
+of characters into two disjoint sets. Any given character matches one, and only
+one, of each pair. The sequences can appear both inside and outside character
+classes. They each match one character of the appropriate type. If the current
+matching point is at the end of the subject string, all of them fail, because
+there is no character to match.
+.P
+The default \es characters are HT (9), LF (10), VT (11), FF (12), CR (13), and
+space (32), which are defined as white space in the "C" locale. This list may
+vary if locale-specific matching is taking place. For example, in some locales
+the "non-breaking space" character (\exA0) is recognized as white space, and in
+others the VT character is not.
+.P
+A "word" character is an underscore or any character that is a letter or digit.
+By default, the definition of letters and digits is controlled by PCRE2's
+low-valued character tables, and may vary if locale-specific matching is taking
+place (see
+.\" HTML 
+.\" 
+"Locale support"
+.\"
+in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+page). For example, in a French locale such as "fr_FR" in Unix-like systems,
+or "french" in Windows, some character codes greater than 127 are used for
+accented letters, and these are then matched by \ew. The use of locales with
+Unicode is discouraged.
+.P
+By default, characters whose code points are greater than 127 never match \ed,
+\es, or \ew, and always match \eD, \eS, and \eW, although this may be different
+for characters in the range 128-255 when locale-specific matching is happening.
+These escape sequences retain their original meanings from before Unicode
+support was available, mainly for efficiency reasons. If the PCRE2_UCP option
+is set, the behaviour is changed so that Unicode properties are used to
+determine character types, as follows:
+.sp
+  \ed  any character that matches \ep{Nd} (decimal digit)
+  \es  any character that matches \ep{Z} or \eh or \ev
+  \ew  any character that matches \ep{L}, \ep{N}, \ep{Mn}, or \ep{Pc}
+.sp
+The addition of \ep{Mn} (non-spacing mark) and the replacement of an explicit
+test for underscore with a test for \ep{Pc} (connector punctuation) happened in
+PCRE2 release 10.43. This brings PCRE2 into line with Perl.
+.P
+The upper case escapes match the inverse sets of characters. Note that \ed
+matches only decimal digits, whereas \ew matches any Unicode digit, as well as
+other character categories. Note also that PCRE2_UCP affects \eb, and
+\eB because they are defined in terms of \ew and \eW. Matching these sequences
+is noticeably slower when PCRE2_UCP is set.
+.P
+The effect of PCRE2_UCP on any one of these escape sequences can be negated by
+the options PCRE2_EXTRA_ASCII_BSD, PCRE2_EXTRA_ASCII_BSS, and
+PCRE2_EXTRA_ASCII_BSW, respectively. These options can be set and reset within
+a pattern by means of an internal option setting
+.\" HTML 
+.\" 
+(see below).
+.\"
+.P
+The sequences \eh, \eH, \ev, and \eV, in contrast to the other sequences, which
+match only ASCII characters by default, always match a specific list of code
+points, whether or not PCRE2_UCP is set. The horizontal space characters are:
+.sp
+  U+0009     Horizontal tab (HT)
+  U+0020     Space
+  U+00A0     Non-break space
+  U+1680     Ogham space mark

+  U+202F     Narrow no-break space
+  U+205F     Medium mathematical space
+  U+3000     Ideographic space
+.sp
+The vertical space characters are:
+.sp
+  U+000A     Linefeed (LF)
+  U+000B     Vertical tab (VT)
+  U+000C     Form feed (FF)
+  U+000D     Carriage return (CR)
+  U+0085     Next line (NEL)
+  U+2028     Line separator
+  U+2029     Paragraph separator
+.sp
+In 8-bit, non-UTF-8 mode, only the characters with code points less than 256
+are relevant.
+.
+.
+.\" HTML 
+.SS "Newline sequences"
+.rs
+.sp
+Outside a character class, by default, the escape sequence \eR matches any
+Unicode newline sequence. In 8-bit non-UTF-8 mode \eR is equivalent to the
+following:
+.sp
+  (?>\er\en|\en|\ex0b|\ef|\er|\ex85)
+.sp
+This is an example of an "atomic group", details of which are given
+.\" HTML 
+.\" 
+below.
+.\"
+This particular group matches either the two-character sequence CR followed by
+LF, or one of the single characters LF (linefeed, U+000A), VT (vertical tab,
+U+000B), FF (form feed, U+000C), CR (carriage return, U+000D), or NEL (next
+line, U+0085). Because this is an atomic group, the two-character sequence is
+treated as a single unit that cannot be split.
+.P
+In other modes, two additional characters whose code points are greater than 255
+are added: LS (line separator, U+2028) and PS (paragraph separator, U+2029).
+Unicode support is not needed for these characters to be recognized.
+.P
+It is possible to restrict \eR to match only CR, LF, or CRLF (instead of the
+complete set of Unicode line endings) by setting the option PCRE2_BSR_ANYCRLF
+at compile time. (BSR is an abbreviation for "backslash R".) This can be made
+the default when PCRE2 is built; if this is the case, the other behaviour can
+be requested via the PCRE2_BSR_UNICODE option. It is also possible to specify
+these settings by starting a pattern string with one of the following
+sequences:
+.sp
+  (*BSR_ANYCRLF)   CR, LF, or CRLF only
+  (*BSR_UNICODE)   any Unicode newline sequence
+.sp
+These override the default and the options given to the compiling function.
+Note that these special settings, which are not Perl-compatible, are recognized
+only at the very start of a pattern, and that they must be in upper case. If
+more than one of them is present, the last one is used. They can be combined
+with a change of newline convention; for example, a pattern can start with:
+.sp
+  (*ANY)(*BSR_ANYCRLF)
+.sp
+They can also be combined with the (*UTF) or (*UCP) special sequences. Inside a
+character class, \eR is treated as an unrecognized escape sequence, and causes
+an error.
+.
+.
+.\" HTML 
+.SS Unicode character properties
+.rs
+.sp
+When PCRE2 is built with Unicode support (the default), three additional escape
+sequences that match characters with specific properties are available. They
+can be used in any mode, though in 8-bit and 16-bit non-UTF modes these
+sequences are of course limited to testing characters whose code points are
+less than U+0100 and U+10000, respectively. In 32-bit non-UTF mode, code points
+greater than 0x10ffff (the Unicode limit) may be encountered. These are all
+treated as being in the Unknown script and with an unassigned type.
+.P
+Matching characters by Unicode property is not fast, because PCRE2 has to do a
+multistage table lookup in order to find a character's property. That is why
+the traditional escape sequences such as \ed and \ew do not use Unicode
+properties in PCRE2 by default, though you can make them do so by setting the
+PCRE2_UCP option or by starting the pattern with (*UCP).
+.P
+The extra escape sequences that provide property support are:
+.sp
+  \ep{\fIxx\fP}   a character with the \fIxx\fP property
+  \eP{\fIxx\fP}   a character without the \fIxx\fP property
+  \eX       a Unicode extended grapheme cluster
+.sp
+The property names represented by \fIxx\fP above are not case-sensitive, and in
+accordance with Unicode's "loose matching" rules, spaces, hyphens, and
+underscores are ignored. There is support for Unicode script names, Unicode
+general category properties, "Any", which matches any character (including
+newline), Bidi_Class, a number of binary (yes/no) properties, and some special
+PCRE2 properties (described
+.\" HTML 
+.\" 
+below).
+.\"
+Certain other Perl properties such as "InMusicalSymbols" are not supported by
+PCRE2. Note that \eP{Any} does not match any characters, so always causes a
+match failure.
+.
+.
+.
+.SS "Script properties for \ep and \eP"
+.rs
+.sp
+There are three different syntax forms for matching a script. Each Unicode
+character has a basic script and, optionally, a list of other scripts ("Script
+Extensions") with which it is commonly used. Using the Adlam script as an
+example, \ep{sc:Adlam} matches characters whose basic script is Adlam, whereas
+\ep{scx:Adlam} matches, in addition, characters that have Adlam in their
+extensions list. The full names "script" and "script extensions" for the
+property types are recognized, and a equals sign is an alternative to the
+colon. If a script name is given without a property type, for example,
+\ep{Adlam}, it is treated as \ep{scx:Adlam}. Perl changed to this
+interpretation at release 5.26 and PCRE2 changed at release 10.40.
+.P
+Unassigned characters (and in non-UTF 32-bit mode, characters with code points
+greater than 0x10FFFF) are assigned the "Unknown" script. Others that are not
+part of an identified script are lumped together as "Common". The current list
+of recognized script names and their 4-character abbreviations can be obtained
+by running this command:
+.sp
+  pcre2test -LS
+.sp
+.
+.
+.
+.SS "The general category property for \ep and \eP"
+.rs
+.sp
+Each character has exactly one Unicode general category property, specified by
+a two-letter abbreviation. For compatibility with Perl, negation can be
+specified by including a circumflex between the opening brace and the property
+name. For example, \ep{^Lu} is the same as \eP{Lu}.
+.P
+If only one letter is specified with \ep or \eP, it includes all the general
+category properties that start with that letter. In this case, in the absence
+of negation, the curly brackets in the escape sequence are optional; these two
+examples have the same effect:
+.sp
+  \ep{L}
+  \epL
+.sp
+The following general category property codes are supported:
+.sp
+  C     Other

+  Zl    Line separator
+  Zp    Paragraph separator
+  Zs    Space separator
+.sp
+The special property LC, which has the synonym L&, is also supported: it
+matches a character that has the Lu, Ll, or Lt property, in other words, a
+letter that is not classified as a modifier or "other".
+.P
+The Cs (Surrogate) property applies only to characters whose code points are in
+the range U+D800 to U+DFFF. These characters are no different to any other
+character when PCRE2 is not in UTF mode (using the 16-bit or 32-bit library).
+However, they are not valid in Unicode strings and so cannot be tested by PCRE2
+in UTF mode, unless UTF validity checking has been turned off (see the
+discussion of PCRE2_NO_UTF_CHECK in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+page).
+.P
+The long synonyms for property names that Perl supports (such as \ep{Letter})
+are not supported by PCRE2, nor is it permitted to prefix any of these
+properties with "Is".
+.P
+No character that is in the Unicode table has the Cn (unassigned) property.
+Instead, this property is assumed for any code point that is not in the
+Unicode table.
+.P
+Specifying caseless matching does not affect these escape sequences. For
+example, \ep{Lu} always matches only upper case letters. This is different from
+the behaviour of current versions of Perl.

+.SS Extended grapheme clusters
+.rs
+.sp
+The \eX escape matches any number of Unicode characters that form an "extended
+grapheme cluster", and treats the sequence as an atomic group
+.\" HTML 
+.\" 
+(see below).
+.\"
+Unicode supports various kinds of composite character by giving each character
+a grapheme breaking property, and having rules that use these properties to
+define the boundaries of extended grapheme clusters. The rules are defined in
+Unicode Standard Annex 29, "Unicode Text Segmentation". Unicode 11.0.0
+abandoned the use of some previous properties that had been used for emojis.
+Instead it introduced various emoji-specific properties. PCRE2 uses only the
+Extended Pictographic property.
+.P
+\eX always matches at least one character. Then it decides whether to add
+additional characters according to the following rules for ending a cluster:
+.P
+1. End at the end of the subject string.
+.P
+2. Do not end between CR and LF; otherwise end after any control character.
+.P
+3. Do not break Hangul (a Korean script) syllable sequences. Hangul characters
+are of five types: L, V, T, LV, and LVT. An L character may be followed by an
+L, V, LV, or LVT character; an LV or V character may be followed by a V or T
+character; an LVT or T character may be followed only by a T character.
+.P
+4. Do not end before extending characters or spacing marks or the zero-width
+joiner (ZWJ) character. Characters with the "mark" property always have the
+"extend" grapheme breaking property.
+.P
+5. Do not end after prepend characters.
+.P
+6. Do not end within emoji modifier sequences or emoji ZWJ (zero-width
+joiner) sequences. An emoji ZWJ sequence consists of a character with the
+Extended_Pictographic property, optionally followed by one or more characters
+with the Extend property, followed by the ZWJ character, followed by another
+Extended_Pictographic character.
+.P
+7. Do not break within emoji flag sequences. That is, do not break between
+regional indicator (RI) characters if there are an odd number of RI characters
+before the break point.
+.P
+8. Otherwise, end the cluster.
+.
+.
+.\" HTML 
+.SS PCRE2's additional properties
+.rs
+.sp
+As well as the standard Unicode properties described above, PCRE2 supports four
+more that make it possible to convert traditional escape sequences such as \ew
+and \es to use Unicode properties. PCRE2 uses these non-standard, non-Perl
+properties internally when PCRE2_UCP is set. However, they may also be used
+explicitly. These properties are:
+.sp
+  Xan   Any alphanumeric character
+  Xps   Any POSIX space character
+  Xsp   Any Perl space character
+  Xwd   Any Perl "word" character
+.sp
+Xan matches characters that have either the L (letter) or the N (number)
+property. Xps matches the characters tab, linefeed, vertical tab, form feed, or
+carriage return, and any other character that has the Z (separator) property.
+Xsp is the same as Xps; in PCRE1 it used to exclude vertical tab, for Perl
+compatibility, but Perl changed. Xwd matches the same characters as Xan, plus
+those that match Mn (non-spacing mark) or Pc (connector punctuation, which
+includes underscore).
+.P
+There is another non-standard property, Xuc, which matches any character that
+can be represented by a Universal Character Name in C++ and other programming
+languages. These are the characters $, @, ` (grave accent), and all characters
+with Unicode code points greater than or equal to U+00A0, except for the
+surrogates U+D800 to U+DFFF. Note that most base (ASCII) characters are
+excluded. (Universal Character Names are of the form \euHHHH or \eUHHHHHHHH
+where H is a hexadecimal digit. Note that the Xuc property does not match these
+sequences but the characters that they represent.)
+.
+.
+.\" HTML 
+.SS "Resetting the match start"
+.rs
+.sp
+In normal use, the escape sequence \eK causes any previously matched characters
+not to be included in the final matched sequence that is returned. For example,
+the pattern:
+.sp
+  foo\eKbar
+.sp
+matches "foobar", but reports that it has matched "bar". \eK does not interact
+with anchoring in any way. The pattern:
+.sp
+  ^foo\eKbar
+.sp
+matches only when the subject begins with "foobar" (in single line mode),
+though it again reports the matched string as "bar". This feature is similar to
+a lookbehind assertion
+.\" HTML 
+.\" 
+(described below),
+.\"
+but the part of the pattern that precedes \eK is not constrained to match a
+limited number of characters, as is required for a lookbehind assertion. The
+use of \eK does not interfere with the setting of
+.\" HTML 
+.\" 
+captured substrings.
+.\"
+For example, when the pattern
+.sp
+  (foo)\eKbar
+.sp
+matches "foobar", the first substring is still set to "foo".
+.P
+From version 5.32.0 Perl forbids the use of \eK in lookaround assertions. From
+release 10.38 PCRE2 also forbids this by default. However, the
+PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK option can be used when calling
+\fBpcre2_compile()\fP to re-enable the previous behaviour. When this option is
+set, \eK is acted upon when it occurs inside positive assertions, but is
+ignored in negative assertions. Note that when a pattern such as (?=ab\eK)
+matches, the reported start of the match can be greater than the end of the
+match. Using \eK in a lookbehind assertion at the start of a pattern can also
+lead to odd effects. For example, consider this pattern:
+.sp
+  (?<=\eKfoo)bar
+.sp
+If the subject is "foobar", a call to \fBpcre2_match()\fP with a starting
+offset of 3 succeeds and reports the matching string as "foobar", that is, the
+start of the reported match is earlier than where the match started.
+.
+.
+.\" HTML 
+.SS "Simple assertions"
+.rs
+.sp
+The final use of backslash is for certain simple assertions. An assertion
+specifies a condition that has to be met at a particular point in a match,
+without consuming any characters from the subject string. The use of
+groups for more complicated assertions is described
+.\" HTML 
+.\" 
+below.
+.\"
+The backslashed assertions are:
+.sp
+  \eb     matches at a word boundary
+  \eB     matches when not at a word boundary
+  \eA     matches at the start of the subject
+  \eZ     matches at the end of the subject
+          also matches before a newline at the end of the subject
+  \ez     matches only at the end of the subject
+  \eG     matches at the first matching position in the subject
+.sp
+Inside a character class, \eb has a different meaning; it matches the backspace
+character. If any other of these assertions appears in a character class, an
+"invalid escape sequence" error is generated.
+.P
+A word boundary is a position in the subject string where the current character
+and the previous character do not both match \ew or \eW (i.e. one matches
+\ew and the other matches \eW), or the start or end of the string if the
+first or last character matches \ew, respectively. When PCRE2 is built with
+Unicode support, the meanings of \ew and \eW can be changed by setting the
+PCRE2_UCP option. When this is done, it also affects \eb and \eB. Neither PCRE2
+nor Perl has a separate "start of word" or "end of word" metasequence. However,
+whatever follows \eb normally determines which it is. For example, the fragment
+\eba matches "a" at the start of a word.
+.P
+The \eA, \eZ, and \ez assertions differ from the traditional circumflex and
+dollar (described in the next section) in that they only ever match at the very
+start and end of the subject string, whatever options are set. Thus, they are
+independent of multiline mode. These three assertions are not affected by the
+PCRE2_NOTBOL or PCRE2_NOTEOL options, which affect only the behaviour of the
+circumflex and dollar metacharacters. However, if the \fIstartoffset\fP
+argument of \fBpcre2_match()\fP is non-zero, indicating that matching is to
+start at a point other than the beginning of the subject, \eA can never match.
+The difference between \eZ and \ez is that \eZ matches before a newline at the
+end of the string as well as at the very end, whereas \ez matches only at the
+end.
+.P
+The \eG assertion is true only when the current matching position is at the
+start point of the matching process, as specified by the \fIstartoffset\fP
+argument of \fBpcre2_match()\fP. It differs from \eA when the value of
+\fIstartoffset\fP is non-zero. By calling \fBpcre2_match()\fP multiple times
+with appropriate arguments, you can mimic Perl's /g option, and it is in this
+kind of implementation where \eG can be useful.
+.P
+Note, however, that PCRE2's implementation of \eG, being true at the starting
+character of the matching process, is subtly different from Perl's, which
+defines it as true at the end of the previous match. In Perl, these can be
+different when the previously matched string was empty. Because PCRE2 does just
+one match at a time, it cannot reproduce this behaviour.
+.P
+If all the alternatives of a pattern begin with \eG, the expression is anchored
+to the starting match position, and the "anchored" flag is set in the compiled
+regular expression.
+.
+.
+.SH "CIRCUMFLEX AND DOLLAR"
+.rs
+.sp
+The circumflex and dollar metacharacters are zero-width assertions. That is,
+they test for a particular condition being true without consuming any
+characters from the subject string. These two metacharacters are concerned with
+matching the starts and ends of lines. If the newline convention is set so that
+only the two-character sequence CRLF is recognized as a newline, isolated CR
+and LF characters are treated as ordinary data characters, and are not
+recognized as newlines.
+.P
+Outside a character class, in the default matching mode, the circumflex
+character is an assertion that is true only if the current matching point is at
+the start of the subject string. If the \fIstartoffset\fP argument of
+\fBpcre2_match()\fP is non-zero, or if PCRE2_NOTBOL is set, circumflex can
+never match if the PCRE2_MULTILINE option is unset. Inside a character class,
+circumflex has an entirely different meaning
+.\" HTML 
+.\" 
+(see below).
+.\"
+.P
+Circumflex need not be the first character of the pattern if a number of
+alternatives are involved, but it should be the first thing in each alternative
+in which it appears if the pattern is ever to match that branch. If all
+possible alternatives start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is said to be an
+"anchored" pattern. (There are also other constructs that can cause a pattern
+to be anchored.)
+.P
+The dollar character is an assertion that is true only if the current matching
+point is at the end of the subject string, or immediately before a newline at
+the end of the string (by default), unless PCRE2_NOTEOL is set. Note, however,
+that it does not actually match the newline. Dollar need not be the last
+character of the pattern if a number of alternatives are involved, but it
+should be the last item in any branch in which it appears. Dollar has no
+special meaning in a character class.
+.P
+The meaning of dollar can be changed so that it matches only at the very end of
+the string, by setting the PCRE2_DOLLAR_ENDONLY option at compile time. This
+does not affect the \eZ assertion.
+.P
+The meanings of the circumflex and dollar metacharacters are changed if the
+PCRE2_MULTILINE option is set. When this is the case, a dollar character
+matches before any newlines in the string, as well as at the very end, and a
+circumflex matches immediately after internal newlines as well as at the start
+of the subject string. It does not match after a newline that ends the string,
+for compatibility with Perl. However, this can be changed by setting the
+PCRE2_ALT_CIRCUMFLEX option.
+.P
+For example, the pattern /^abc$/ matches the subject string "def\enabc" (where
+\en represents a newline) in multiline mode, but not otherwise. Consequently,
+patterns that are anchored in single line mode because all branches start with
+^ are not anchored in multiline mode, and a match for circumflex is possible
+when the \fIstartoffset\fP argument of \fBpcre2_match()\fP is non-zero. The
+PCRE2_DOLLAR_ENDONLY option is ignored if PCRE2_MULTILINE is set.
+.P
+When the newline convention (see
+.\" HTML 
+.\" 
+"Newline conventions"
+.\"
+below) recognizes the two-character sequence CRLF as a newline, this is
+preferred, even if the single characters CR and LF are also recognized as
+newlines. For example, if the newline convention is "any", a multiline mode
+circumflex matches before "xyz" in the string "abc\er\enxyz" rather than after
+CR, even though CR on its own is a valid newline. (It also matches at the very
+start of the string, of course.)
+.P
+Note that the sequences \eA, \eZ, and \ez can be used to match the start and
+end of the subject in both modes, and if all branches of a pattern start with
+\eA it is always anchored, whether or not PCRE2_MULTILINE is set.
+.
+.
+.\" HTML 
+.SH "FULL STOP (PERIOD, DOT) AND \eN"
+.rs
+.sp
+Outside a character class, a dot in the pattern matches any one character in
+the subject string except (by default) a character that signifies the end of a
+line. One or more characters may be specified as line terminators (see
+.\" HTML 
+.\" 
+"Newline conventions"
+.\"
+above).
+.P
+Dot never matches a single line-ending character. When the two-character
+sequence CRLF is the only line ending, dot does not match CR if it is
+immediately followed by LF, but otherwise it matches all characters (including
+isolated CRs and LFs). When ANYCRLF is selected for line endings, no occurrences
+of CR of LF match dot. When all Unicode line endings are being recognized, dot
+does not match CR or LF or any of the other line ending characters.
+.P
+The behaviour of dot with regard to newlines can be changed. If the
+PCRE2_DOTALL option is set, a dot matches any one character, without exception.
+If the two-character sequence CRLF is present in the subject string, it takes
+two dots to match it.
+.P
+The handling of dot is entirely independent of the handling of circumflex and
+dollar, the only relationship being that they both involve newlines. Dot has no
+special meaning in a character class.
+.P
+The escape sequence \eN when not followed by an opening brace behaves like a
+dot, except that it is not affected by the PCRE2_DOTALL option. In other words,
+it matches any character except one that signifies the end of a line.
+.P
+When \eN is followed by an opening brace it has a different meaning. See the
+section entitled
+.\" HTML 
+.\" 
+"Non-printing characters"
+.\"
+above for details. Perl also uses \eN{name} to specify characters by Unicode
+name; PCRE2 does not support this.
+.
+.
+.SH "MATCHING A SINGLE CODE UNIT"
+.rs
+.sp
+Outside a character class, the escape sequence \eC matches any one code unit,
+whether or not a UTF mode is set. In the 8-bit library, one code unit is one
+byte; in the 16-bit library it is a 16-bit unit; in the 32-bit library it is a
+32-bit unit. Unlike a dot, \eC always matches line-ending characters. The
+feature is provided in Perl in order to match individual bytes in UTF-8 mode,
+but it is unclear how it can usefully be used.
+.P
+Because \eC breaks up characters into individual code units, matching one unit
+with \eC in UTF-8 or UTF-16 mode means that the rest of the string may start
+with a malformed UTF character. This has undefined results, because PCRE2
+assumes that it is matching character by character in a valid UTF string (by
+default it checks the subject string's validity at the start of processing
+unless the PCRE2_NO_UTF_CHECK or PCRE2_MATCH_INVALID_UTF option is used).
+.P
+An application can lock out the use of \eC by setting the
+PCRE2_NEVER_BACKSLASH_C option when compiling a pattern. It is also possible to
+build PCRE2 with the use of \eC permanently disabled.
+.P
+PCRE2 does not allow \eC to appear in lookbehind assertions
+.\" HTML 
+.\" 
+(described below)
+.\"
+in UTF-8 or UTF-16 modes, because this would make it impossible to calculate
+the length of the lookbehind. Neither the alternative matching function
+\fBpcre2_dfa_match()\fP nor the JIT optimizer support \eC in these UTF modes.
+The former gives a match-time error; the latter fails to optimize and so the
+match is always run using the interpreter.
+.P
+In the 32-bit library, however, \eC is always supported (when not explicitly
+locked out) because it always matches a single code unit, whether or not UTF-32
+is specified.
+.P
+In general, the \eC escape sequence is best avoided. However, one way of using
+it that avoids the problem of malformed UTF-8 or UTF-16 characters is to use a
+lookahead to check the length of the next character, as in this pattern, which
+could be used with a UTF-8 string (ignore white space and line breaks):
+.sp
+  (?| (?=[\ex00-\ex7f])(\eC) |
+      (?=[\ex80-\ex{7ff}])(\eC)(\eC) |
+      (?=[\ex{800}-\ex{ffff}])(\eC)(\eC)(\eC) |
+      (?=[\ex{10000}-\ex{1fffff}])(\eC)(\eC)(\eC)(\eC))
+.sp
+In this example, a group that starts with (?| resets the capturing parentheses
+numbers in each alternative (see
+.\" HTML 
+.\" 
+"Duplicate Group Numbers"
+.\"
+below). The assertions at the start of each branch check the next UTF-8
+character for values whose encoding uses 1, 2, 3, or 4 bytes, respectively. The
+character's individual bytes are then captured by the appropriate number of
+\eC groups.
+.
+.
+.\" HTML 
+.SH "SQUARE BRACKETS AND CHARACTER CLASSES"
+.rs
+.sp
+An opening square bracket introduces a character class, terminated by a closing
+square bracket. A closing square bracket on its own is not special by default.
+If a closing square bracket is required as a member of the class, it should be
+the first data character in the class (after an initial circumflex, if present)
+or escaped with a backslash. This means that, by default, an empty class cannot
+be defined. However, if the PCRE2_ALLOW_EMPTY_CLASS option is set, a closing
+square bracket at the start does end the (empty) class.
+.P
+A character class matches a single character in the subject. A matched
+character must be in the set of characters defined by the class, unless the
+first character in the class definition is a circumflex, in which case the
+subject character must not be in the set defined by the class. If a circumflex
+is actually required as a member of the class, ensure it is not the first
+character, or escape it with a backslash.
+.P
+For example, the character class [aeiou] matches any lower case vowel, while
+[^aeiou] matches any character that is not a lower case vowel. Note that a
+circumflex is just a convenient notation for specifying the characters that
+are in the class by enumerating those that are not. A class that starts with a
+circumflex is not an assertion; it still consumes a character from the subject
+string, and therefore it fails if the current pointer is at the end of the
+string.
+.P
+Characters in a class may be specified by their code points using \eo, \ex, or
+\eN{U+hh..} in the usual way. When caseless matching is set, any letters in a
+class represent both their upper case and lower case versions, so for example,
+a caseless [aeiou] matches "A" as well as "a", and a caseless [^aeiou] does not
+match "A", whereas a caseful version would. Note that there are two ASCII
+characters, K and S, that, in addition to their lower case ASCII equivalents,
+are case-equivalent with Unicode U+212A (Kelvin sign) and U+017F (long S)
+respectively when either PCRE2_UTF or PCRE2_UCP is set.
+.P
+Characters that might indicate line breaks are never treated in any special way
+when matching character classes, whatever line-ending sequence is in use, and
+whatever setting of the PCRE2_DOTALL and PCRE2_MULTILINE options is used. A
+class such as [^a] always matches one of these characters.
+.P
+The generic character type escape sequences \ed, \eD, \eh, \eH, \ep, \eP, \es,
+\eS, \ev, \eV, \ew, and \eW may appear in a character class, and add the
+characters that they match to the class. For example, [\edABCDEF] matches any
+hexadecimal digit. In UTF modes, the PCRE2_UCP option affects the meanings of
+\ed, \es, \ew and their upper case partners, just as it does when they appear
+outside a character class, as described in the section entitled
+.\" HTML 
+.\" 
+"Generic character types"
+.\"
+above. The escape sequence \eb has a different meaning inside a character
+class; it matches the backspace character. The sequences \eB, \eR, and \eX are
+not special inside a character class. Like any other unrecognized escape
+sequences, they cause an error. The same is true for \eN when not followed by
+an opening brace.
+.P
+The minus (hyphen) character can be used to specify a range of characters in a
+character class. For example, [d-m] matches any letter between d and m,
+inclusive. If a minus character is required in a class, it must be escaped with
+a backslash or appear in a position where it cannot be interpreted as
+indicating a range, typically as the first or last character in the class,
+or immediately after a range. For example, [b-d-z] matches letters in the range
+b to d, a hyphen character, or z.
+.P
+Perl treats a hyphen as a literal if it appears before or after a POSIX class
+(see below) or before or after a character type escape such as \ed or \eH.
+However, unless the hyphen is the last character in the class, Perl outputs a
+warning in its warning mode, as this is most likely a user error. As PCRE2 has
+no facility for warning, an error is given in these cases.
+.P
+It is not possible to have the literal character "]" as the end character of a
+range. A pattern such as [W-]46] is interpreted as a class of two characters
+("W" and "-") followed by a literal string "46]", so it would match "W46]" or
+"-46]". However, if the "]" is escaped with a backslash it is interpreted as
+the end of range, so [W-\e]46] is interpreted as a class containing a range
+followed by two other characters. The octal or hexadecimal representation of
+"]" can also be used to end a range.
+.P
+Ranges normally include all code points between the start and end characters,
+inclusive. They can also be used for code points specified numerically, for
+example [\e000-\e037]. Ranges can include any characters that are valid for the
+current mode. In any UTF mode, the so-called "surrogate" characters (those
+whose code points lie between 0xd800 and 0xdfff inclusive) may not be specified
+explicitly by default (the PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES option disables
+this check). However, ranges such as [\ex{d7ff}-\ex{e000}], which include the
+surrogates, are always permitted.
+.P
+There is a special case in EBCDIC environments for ranges whose end points are
+both specified as literal letters in the same case. For compatibility with
+Perl, EBCDIC code points within the range that are not letters are omitted. For
+example, [h-k] matches only four characters, even though the codes for h and k
+are 0x88 and 0x92, a range of 11 code points. However, if the range is
+specified numerically, for example, [\ex88-\ex92] or [h-\ex92], all code points
+are included.
+.P
+If a range that includes letters is used when caseless matching is set, it
+matches the letters in either case. For example, [W-c] is equivalent to
+[][\e\e^_`wxyzabc], matched caselessly, and in a non-UTF mode, if character
+tables for a French locale are in use, [\exc8-\excb] matches accented E
+characters in both cases.
+.P
+A circumflex can conveniently be used with the upper case character types to
+specify a more restricted set of characters than the matching lower case type.
+For example, the class [^\eW_] matches any letter or digit, but not underscore,
+whereas [\ew] includes underscore. A positive character class should be read as
+"something OR something OR ..." and a negative class as "NOT something AND NOT
+something AND NOT ...".
+.P
+The only metacharacters that are recognized in character classes are backslash,
+hyphen (only where it can be interpreted as specifying a range), circumflex
+(only at the start), opening square bracket (only when it can be interpreted as
+introducing a POSIX class name, or for a special compatibility feature - see
+the next two sections), and the terminating closing square bracket. However,
+escaping other non-alphanumeric characters does no harm.
+.
+.
+.SH "POSIX CHARACTER CLASSES"
+.rs
+.sp
+Perl supports the POSIX notation for character classes. This uses names
+enclosed by [: and :] within the enclosing square brackets. PCRE2 also supports
+this notation. For example,
+.sp
+  [01[:alpha:]%]
+.sp
+matches "0", "1", any alphabetic character, or "%". The supported class names
+are:
+.sp
+  alnum    letters and digits
+  alpha    letters
+  ascii    character codes 0 - 127
+  blank    space or tab only
+  cntrl    control characters
+  digit    decimal digits (same as \ed)
+  graph    printing characters, excluding space
+  lower    lower case letters
+  print    printing characters, including space
+  punct    printing characters, excluding letters and digits and space
+  space    white space (the same as \es from PCRE2 8.34)
+  upper    upper case letters
+  word     "word" characters (same as \ew)
+  xdigit   hexadecimal digits
+.sp
+The default "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13),
+and space (32). If locale-specific matching is taking place, the list of space
+characters may be different; there may be fewer or more of them. "Space" and
+\es match the same set of characters, as do "word" and \ew.
+.P
+The name "word" is a Perl extension, and "blank" is a GNU extension from Perl
+5.8. Another Perl extension is negation, which is indicated by a ^ character
+after the colon. For example,
+.sp
+  [12[:^digit:]]
+.sp
+matches "1", "2", or any non-digit. PCRE2 (and Perl) also recognize the POSIX
+syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not
+supported, and an error is given if they are encountered.
+.P
+By default, characters with values greater than 127 do not match any of the
+POSIX character classes, although this may be different for characters in the
+range 128-255 when locale-specific matching is happening. However, in UCP mode,
+unless certain options are set (see below), some of the classes are changed so
+that Unicode character properties are used. This is achieved by replacing
+POSIX classes with other sequences, as follows:
+.sp
+  [:alnum:]  becomes  \ep{Xan}
+  [:alpha:]  becomes  \ep{L}
+  [:blank:]  becomes  \eh
+  [:cntrl:]  becomes  \ep{Cc}
+  [:digit:]  becomes  \ep{Nd}
+  [:lower:]  becomes  \ep{Ll}
+  [:space:]  becomes  \ep{Xps}
+  [:upper:]  becomes  \ep{Lu}
+  [:word:]   becomes  \ep{Xwd}
+.sp
+Negated versions, such as [:^alpha:] use \eP instead of \ep. Four other POSIX
+classes are handled specially in UCP mode:
+.TP 10
+[:graph:]

+The other POSIX classes are unchanged by PCRE2_UCP, and match only characters

+There are two options that can be used to restrict the POSIX classes to ASCII

+just [:digit:] and [:xdigit:]. Within a pattern, this can be set and unset by
+(?aT) and (?-aT). The PCRE2_EXTRA_ASCII_POSIX option disables UCP processing
+for all POSIX classes, including [:digit:] and [:xdigit:]. Within a pattern,
+(?aP) and (?-aP) set and unset both these options for consistency.

+.
+.SH "COMPATIBILITY FEATURE FOR WORD BOUNDARIES"
+.rs
+.sp
+In the POSIX.2 compliant library that was included in 4.4BSD Unix, the ugly
+syntax [[:<:]] and [[:>:]] is used for matching "start of word" and "end of
+word". PCRE2 treats these items as follows:
+.sp
+  [[:<:]]  is converted to  \eb(?=\ew)
+  [[:>:]]  is converted to  \eb(?<=\ew)
+.sp
+Only these exact character sequences are recognized. A sequence such as
+[a[:<:]b] provokes error for an unrecognized POSIX class name. This support is
+not compatible with Perl. It is provided to help migrations from other
+environments, and is best not used in any new patterns. Note that \eb matches
+at the start and the end of a word (see
+.\" HTML 
+.\" 
+"Simple assertions"
+.\"
+above), and in a Perl-style pattern the preceding or following character
+normally shows which is wanted, without the need for the assertions that are
+used above in order to give exactly the POSIX behaviour. Note also that the
+PCRE2_UCP option changes the meaning of \ew (and therefore \eb) by default, so
+it also affects these POSIX sequences.
+.
+.
+.SH "VERTICAL BAR"
+.rs
+.sp
+Vertical bar characters are used to separate alternative patterns. For example,
+the pattern
+.sp
+  gilbert|sullivan
+.sp
+matches either "gilbert" or "sullivan". Any number of alternatives may appear,
+and an empty alternative is permitted (matching the empty string). The matching
+process tries each alternative in turn, from left to right, and the first one
+that succeeds is used. If the alternatives are within a group
+.\" HTML

+alternative in the group.
+.
+.
+.\" HTML 
+.SH "INTERNAL OPTION SETTING"
+.rs
+.sp
+The settings of several options can be changed within a pattern by a sequence
+of letters enclosed between "(?" and ")". The following are Perl-compatible,
+and are described in detail in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation. The option letters are:
+.sp
+  i  for PCRE2_CASELESS
+  m  for PCRE2_MULTILINE
+  n  for PCRE2_NO_AUTO_CAPTURE
+  s  for PCRE2_DOTALL
+  x  for PCRE2_EXTENDED
+  xx for PCRE2_EXTENDED_MORE
+.sp
+For example, (?im) sets caseless, multiline matching. It is also possible to
+unset these options by preceding the relevant letters with a hyphen, for
+example (?-im). The two "extended" options are not independent; unsetting
+either one cancels the effects of both of them.
+.P
+A combined setting and unsetting such as (?im-sx), which sets PCRE2_CASELESS
+and PCRE2_MULTILINE while unsetting PCRE2_DOTALL and PCRE2_EXTENDED, is also
+permitted. Only one hyphen may appear in the options string. If a letter
+appears both before and after the hyphen, the option is unset. An empty options
+setting "(?)" is allowed. Needless to say, it has no effect.
+.P
+If the first character following (? is a circumflex, it causes all of the above
+options to be unset. Letters may follow the circumflex to cause some options to
+be re-instated, but a hyphen may not appear.
+.P
+Some PCRE2-specific options can be changed by the same mechanism using these
+pairs or individual letters:
+.sp
+  aD for PCRE2_EXTRA_ASCII_BSD
+  aS for PCRE2_EXTRA_ASCII_BSS
+  aW for PCRE2_EXTRA_ASCII_BSW
+  aP for PCRE2_EXTRA_ASCII_POSIX and PCRE2_EXTRA_ASCII_DIGIT
+  aT for PCRE2_EXTRA_ASCII_DIGIT
+  r  for PCRE2_EXTRA_CASELESS_RESTRICT
+  J  for PCRE2_DUPNAMES
+  U  for PCRE2_UNGREEDY
+.sp
+However, except for 'r', these are not unset by (?^), which is equivalent to
+(?-imnrsx). If 'a' is not followed by any of the upper case letters shown
+above, it sets (or unsets) all the ASCII options.
+.P
+PCRE2_EXTRA_ASCII_DIGIT has no additional effect when PCRE2_EXTRA_ASCII_POSIX
+is set, but including it in (?aP) means that (?-aP) suppresses all ASCII
+restrictions for POSIX classes.
+.P
+When one of these option changes occurs at top level (that is, not inside group
+parentheses), the change applies until a subsequent change, or the end of the
+pattern. An option change within a group (see below for a description of
+groups) affects only that part of the group that follows it. At the end of the
+group these options are reset to the state they were before the group. For
+example,
+.sp
+  (a(?i)b)c
+.sp
+matches abc and aBc and no other strings (assuming PCRE2_CASELESS is not set
+externally). Any changes made in one alternative do carry on into subsequent
+branches within the same group. For example,
+.sp
+  (a(?i)b|c)
+.sp
+matches "ab", "aB", "c", and "C", even though when matching "C" the first
+branch is abandoned before the option setting. This is because the effects of
+option settings happen at compile time. There would be some very weird
+behaviour otherwise.
+.P
+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing group (see the next section), the option letters may
+appear between the "?" and the ":". Thus the two patterns
+.sp
+  (?i:saturday|sunday)
+  (?:(?i)saturday|sunday)
+.sp
+match exactly the same set of strings.
+.P
+\fBNote:\fP There are other PCRE2-specific options, applying to the whole
+pattern, which can be set by the application when the compiling function is
+called. In addition, the pattern can contain special leading sequences such as
+(*CRLF) to override what the application has set or what has been defaulted.
+Details are given in the section entitled
+.\" HTML 
+.\" 
+"Newline sequences"
+.\"
+above. There are also the (*UTF) and (*UCP) leading sequences that can be used
+to set UTF and Unicode property modes; they are equivalent to setting the
+PCRE2_UTF and PCRE2_UCP options, respectively. However, the application can set
+the PCRE2_NEVER_UTF or PCRE2_NEVER_UCP options, which lock out the use of the
+(*UTF) and (*UCP) sequences.
+.
+.
+.\" HTML 
+.SH GROUPS
+.rs
+.sp
+Groups are delimited by parentheses (round brackets), which can be nested.
+Turning part of a pattern into a group does two things:
+.sp
+1. It localizes a set of alternatives. For example, the pattern
+.sp
+  cat(aract|erpillar|)
+.sp
+matches "cataract", "caterpillar", or "cat". Without the parentheses, it would
+match "cataract", "erpillar" or an empty string.
+.sp
+2. It creates a "capture group". This means that, when the whole pattern
+matches, the portion of the subject string that matched the group is passed
+back to the caller, separately from the portion that matched the whole pattern.
+(This applies only to the traditional matching function; the DFA matching
+function does not support capturing.)
+.P
+Opening parentheses are counted from left to right (starting from 1) to obtain
+numbers for capture groups. For example, if the string "the red king" is
+matched against the pattern
+.sp
+  the ((red|white) (king|queen))
+.sp
+the captured substrings are "red king", "red", and "king", and are numbered 1,
+2, and 3, respectively.
+.P
+The fact that plain parentheses fulfil two functions is not always helpful.
+There are often times when grouping is required without capturing. If an
+opening parenthesis is followed by a question mark and a colon, the group
+does not do any capturing, and is not counted when computing the number of any
+subsequent capture groups. For example, if the string "the white queen"
+is matched against the pattern
+.sp
+  the ((?:red|white) (king|queen))
+.sp
+the captured substrings are "white queen" and "queen", and are numbered 1 and
+2. The maximum number of capture groups is 65535.
+.P
+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing group, the option letters may appear between the "?" and the
+":". Thus the two patterns
+.sp
+  (?i:saturday|sunday)
+  (?:(?i)saturday|sunday)
+.sp
+match exactly the same set of strings. Because alternative branches are tried
+from left to right, and options are not reset until the end of the group is
+reached, an option setting in one branch does affect subsequent branches, so
+the above patterns match "SUNDAY" as well as "Saturday".
+.
+.
+.\" HTML 
+.SH "DUPLICATE GROUP NUMBERS"
+.rs
+.sp
+Perl 5.10 introduced a feature whereby each alternative in a group uses the
+same numbers for its capturing parentheses. Such a group starts with (?| and is
+itself a non-capturing group. For example, consider this pattern:
+.sp
+  (?|(Sat)ur|(Sun))day
+.sp
+Because the two alternatives are inside a (?| group, both sets of capturing
+parentheses are numbered one. Thus, when the pattern matches, you can look
+at captured substring number one, whichever alternative matched. This construct
+is useful when you want to capture part, but not all, of one of a number of
+alternatives. Inside a (?| group, parentheses are numbered as usual, but the
+number is reset at the start of each branch. The numbers of any capturing
+parentheses that follow the whole group start after the highest number used in
+any branch. The following example is taken from the Perl documentation. The
+numbers underneath show in which buffer the captured content will be stored.
+.sp
+  # before  ---------------branch-reset----------- after
+  / ( a )  (?| x ( y ) z | (p (q) r) | (t) u (v) ) ( z ) /x
+  # 1            2         2  3        2     3     4
+.sp
+A backreference to a capture group uses the most recent value that is set for
+the group. The following pattern matches "abcabc" or "defdef":
+.sp
+  /(?|(abc)|(def))\e1/
+.sp
+In contrast, a subroutine call to a capture group always refers to the
+first one in the pattern with the given number. The following pattern matches
+"abcabc" or "defabc":
+.sp
+  /(?|(abc)|(def))(?1)/
+.sp
+A relative reference such as (?-1) is no different: it is just a convenient way
+of computing an absolute group number.
+.P
+If a
+.\" HTML 
+.\" 
+condition test
+.\"
+for a group's having matched refers to a non-unique number, the test is
+true if any group with that number has matched.
+.P
+An alternative approach to using this "branch reset" feature is to use
+duplicate named groups, as described in the next section.
+.
+.
+.SH "NAMED CAPTURE GROUPS"
+.rs
+.sp
+Identifying capture groups by number is simple, but it can be very hard to keep
+track of the numbers in complicated patterns. Furthermore, if an expression is
+modified, the numbers may change. To help with this difficulty, PCRE2 supports
+the naming of capture groups. This feature was not added to Perl until release
+5.10. Python had the feature earlier, and PCRE1 introduced it at release 4.0,
+using the Python syntax. PCRE2 supports both the Perl and the Python syntax.
+.P
+In PCRE2, a capture group can be named in one of three ways: (?...) or
+(?'name'...) as in Perl, or (?P...) as in Python. Names may be up to 128
+code units long. When PCRE2_UTF is not set, they may contain only ASCII
+alphanumeric characters and underscores, but must start with a non-digit. When
+PCRE2_UTF is set, the syntax of group names is extended to allow any Unicode
+letter or Unicode decimal digit. In other words, group names must match one of
+these patterns:
+.sp
+  ^[_A-Za-z][_A-Za-z0-9]*\ez   when PCRE2_UTF is not set
+  ^[_\ep{L}][_\ep{L}\ep{Nd}]*\ez  when PCRE2_UTF is set
+.sp
+References to capture groups from other parts of the pattern, such as
+.\" HTML 
+.\" 
+backreferences,
+.\"
+.\" HTML 
+.\" 
+recursion,
+.\"
+and
+.\" HTML 
+.\" 
+conditions,
+.\"
+can all be made by name as well as by number.
+.P
+Named capture groups are allocated numbers as well as names, exactly as
+if the names were not present. In both PCRE2 and Perl, capture groups
+are primarily identified by numbers; any names are just aliases for these
+numbers. The PCRE2 API provides function calls for extracting the complete
+name-to-number translation table from a compiled pattern, as well as
+convenience functions for extracting captured substrings by name.
+.P
+\fBWarning:\fP When more than one capture group has the same number, as
+described in the previous section, a name given to one of them applies to all
+of them. Perl allows identically numbered groups to have different names.
+Consider this pattern, where there are two capture groups, both numbered 1:
+.sp
+  (?|(?aa)|(?bb))
+.sp
+Perl allows this, with both names AA and BB as aliases of group 1. Thus, after
+a successful match, both names yield the same value (either "aa" or "bb").
+.P
+In an attempt to reduce confusion, PCRE2 does not allow the same group number
+to be associated with more than one name. The example above provokes a
+compile-time error. However, there is still scope for confusion. Consider this
+pattern:
+.sp
+  (?|(?aa)|(bb))
+.sp
+Although the second group number 1 is not explicitly named, the name AA is
+still an alias for any group 1. Whether the pattern matches "aa" or "bb", a
+reference by name to group AA yields the matched string.
+.P
+By default, a name must be unique within a pattern, except that duplicate names
+are permitted for groups with the same number, for example:
+.sp
+  (?|(?aa)|(?bb))
+.sp
+The duplicate name constraint can be disabled by setting the PCRE2_DUPNAMES
+option at compile time, or by the use of (?J) within the pattern, as described
+in the section entitled
+.\" HTML 
+.\" 
+"Internal Option Setting"
+.\"
+above.
+.P
+Duplicate names can be useful for patterns where only one instance of the named
+capture group can match. Suppose you want to match the name of a weekday,
+either as a 3-letter abbreviation or as the full name, and in both cases you
+want to extract the abbreviation. This pattern (ignoring the line breaks) does
+the job:
+.sp
+  (?J)
+  (?Mon|Fri|Sun)(?:day)?|
+  (?Tue)(?:sday)?|
+  (?Wed)(?:nesday)?|
+  (?Thu)(?:rsday)?|
+  (?Sat)(?:urday)?
+.sp
+There are five capture groups, but only one is ever set after a match. The
+convenience functions for extracting the data by name returns the substring for
+the first (and in this example, the only) group of that name that matched. This
+saves searching to find which numbered group it was. (An alternative way of
+solving this problem is to use a "branch reset" group, as described in the
+previous section.)
+.P
+If you make a backreference to a non-unique named group from elsewhere in the
+pattern, the groups to which the name refers are checked in the order in which
+they appear in the overall pattern. The first one that is set is used for the
+reference. For example, this pattern matches both "foofoo" and "barbar" but not
+"foobar" or "barfoo":
+.sp
+  (?J)(?:(?foo)|(?bar))\ek
+.sp
+.P
+If you make a subroutine call to a non-unique named group, the one that
+corresponds to the first occurrence of the name is used. In the absence of
+duplicate numbers this is the one with the lowest number.
+.P
+If you use a named reference in a condition
+test (see the
+.\"
+.\" HTML 
+.\" 
+section about conditions
+.\"
+below), either to check whether a capture group has matched, or to check for
+recursion, all groups with the same name are tested. If the condition is true
+for any one of them, the overall condition is true. This is the same behaviour
+as testing by number. For further details of the interfaces for handling named
+capture groups, see the
+.\" HREF
+\fBpcre2api\fP

+documentation.
+.
+.
+.SH REPETITION
+.rs
+.sp
+Repetition is specified by quantifiers, which may follow any one of these
+items:
+.sp
+  a literal data character
+  the dot metacharacter
+  the \eC escape sequence
+  the \eR escape sequence
+  the \eX escape sequence
+  any escape sequence that matches a single character
+  a character class
+  a backreference
+  a parenthesized group (including lookaround assertions)
+  a subroutine call (recursive or otherwise)
+.sp
+If a quantifier does not follow a repeatable item, an error occurs. The
+general repetition quantifier specifies a minimum and maximum number of
+permitted matches by giving two numbers in curly brackets (braces), separated
+by a comma. The numbers must be less than 65536, and the first must be less
+than or equal to the second. For example,
+.sp
+  z{2,4}
+.sp
+matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special
+character. If the second number is omitted, but the comma is present, there is
+no upper limit; if the second number and the comma are both omitted, the
+quantifier specifies an exact number of required matches. Thus
+.sp
+  [aeiou]{3,}
+.sp
+matches at least 3 successive vowels, but may match many more, whereas
+.sp
+  \ed{8}
+.sp
+matches exactly 8 digits. If the first number is omitted, the lower limit is
+taken as zero; in this case the upper limit must be present.
+.sp
+  X{,4} is interpreted as X{0,4}
+.sp
+This is a change in behaviour that happened in Perl 5.34.0 and PCRE2 10.43. In
+earlier versions such a sequence was not interpreted as a quantifier. Other
+regular expression engines may behave either way.
+.P
+If the characters that follow an opening brace do not match the syntax of a
+quantifier, the brace is taken as a literal character. In particular, this
+means that {,} is a literal string of three characters.
+.P
+Note that not every opening brace is potentially the start of a quantifier
+because braces are used in other items such as \eN{U+345} or \ek{name}.
+.P
+In UTF modes, quantifiers apply to characters rather than to individual code
+units. Thus, for example, \ex{100}{2} matches two characters, each of
+which is represented by a two-byte sequence in a UTF-8 string. Similarly,
+\eX{3} matches three Unicode extended grapheme clusters, each of which may be
+several code units long (and they may be of different lengths).
+.P
+The quantifier {0} is permitted, causing the expression to behave as if the
+previous item and the quantifier were not present. This may be useful for
+capture groups that are referenced as
+.\" HTML 
+.\" 
+subroutines
+.\"
+from elsewhere in the pattern (but see also the section entitled
+.\" HTML 
+.\" 
+"Defining capture groups for use by reference only"
+.\"
+below). Except for parenthesized groups, items that have a {0} quantifier are
+omitted from the compiled pattern.
+.P
+For convenience, the three most common quantifiers have single-character
+abbreviations:
+.sp
+  *    is equivalent to {0,}
+  +    is equivalent to {1,}
+  ?    is equivalent to {0,1}
+.sp
+It is possible to construct infinite loops by following a group that can match
+no characters with a quantifier that has no upper limit, for example:
+.sp
+  (a?)*
+.sp
+Earlier versions of Perl and PCRE1 used to give an error at compile time for
+such patterns. However, because there are cases where this can be useful, such
+patterns are now accepted, but whenever an iteration of such a group matches no
+characters, matching moves on to the next item in the pattern instead of
+repeatedly matching an empty string. This does not prevent backtracking into
+any of the iterations if a subsequent item fails to match.
+.P
+By default, quantifiers are "greedy", that is, they match as much as possible
+(up to the maximum number of permitted repetitions), without causing the rest
+of the pattern to fail. The classic example of where this gives problems is in
+trying to match comments in C programs. These appear between /* and */ and
+within the comment, individual * and / characters may appear. An attempt to
+match C comments by applying the pattern
+.sp
+  /\e*.*\e*/
+.sp
+to the string
+.sp
+  /* first comment */  not comment  /* second comment */
+.sp
+fails, because it matches the entire string owing to the greediness of the .*
+item. However, if a quantifier is followed by a question mark, it ceases to be
+greedy, and instead matches the minimum number of times possible, so the
+pattern
+.sp
+  /\e*.*?\e*/
+.sp
+does the right thing with C comments. The meaning of the various quantifiers is
+not otherwise changed, just the preferred number of matches. Do not confuse
+this use of question mark with its use as a quantifier in its own right.
+Because it has two uses, it can sometimes appear doubled, as in
+.sp
+  \ed??\ed
+.sp
+which matches one digit by preference, but can match two if that is the only
+way the rest of the pattern matches.
+.P
+If the PCRE2_UNGREEDY option is set (an option that is not available in Perl),
+the quantifiers are not greedy by default, but individual ones can be made
+greedy by following them with a question mark. In other words, it inverts the
+default behaviour.
+.P
+When a parenthesized group is quantified with a minimum repeat count that
+is greater than 1 or with a limited maximum, more memory is required for the
+compiled pattern, in proportion to the size of the minimum or maximum.
+.P
+If a pattern starts with .* or .{0,} and the PCRE2_DOTALL option (equivalent
+to Perl's /s) is set, thus allowing the dot to match newlines, the pattern is
+implicitly anchored, because whatever follows will be tried against every
+character position in the subject string, so there is no point in retrying the
+overall match at any position after the first. PCRE2 normally treats such a
+pattern as though it were preceded by \eA.
+.P
+In cases where it is known that the subject string contains no newlines, it is
+worth setting PCRE2_DOTALL in order to obtain this optimization, or
+alternatively, using ^ to indicate anchoring explicitly.
+.P
+However, there are some cases where the optimization cannot be used. When .*
+is inside capturing parentheses that are the subject of a backreference
+elsewhere in the pattern, a match at the start may fail where a later one
+succeeds. Consider, for example:
+.sp
+  (.*)abc\e1
+.sp
+If the subject is "xyz123abc123" the match point is the fourth character. For
+this reason, such a pattern is not implicitly anchored.
+.P
+Another case where implicit anchoring is not applied is when the leading .* is
+inside an atomic group. Once again, a match at the start may fail where a later
+one succeeds. Consider this pattern:
+.sp
+  (?>.*?a)b
+.sp
+It matches "ab" in the subject "aab". The use of the backtracking control verbs
+(*PRUNE) and (*SKIP) also disable this optimization, and there is an option,
+PCRE2_NO_DOTSTAR_ANCHOR, to do so explicitly.
+.P
+When a capture group is repeated, the value captured is the substring that
+matched the final iteration. For example, after
+.sp
+  (tweedle[dume]{3}\es*)+
+.sp
+has matched "tweedledum tweedledee" the value of the captured substring is
+"tweedledee". However, if there are nested capture groups, the corresponding
+captured values may have been set in previous iterations. For example, after
+.sp
+  (a|(b))+
+.sp
+matches "aba" the value of the second captured substring is "b".

+.\" HTML 
+.SH "ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS"
+.rs
+.sp
+With both maximizing ("greedy") and minimizing ("ungreedy" or "lazy")
+repetition, failure of what follows normally causes the repeated item to be
+re-evaluated to see if a different number of repeats allows the rest of the
+pattern to match. Sometimes it is useful to prevent this, either to change the
+nature of the match, or to cause it fail earlier than it otherwise might, when
+the author of the pattern knows there is no point in carrying on.
+.P
+Consider, for example, the pattern \ed+foo when applied to the subject line
+.sp
+  123456bar
+.sp
+After matching all 6 digits and then failing to match "foo", the normal
+action of the matcher is to try again with only 5 digits matching the \ed+
+item, and then with 4, and so on, before ultimately failing. "Atomic grouping"
+(a term taken from Jeffrey Friedl's book) provides the means for specifying
+that once a group has matched, it is not to be re-evaluated in this way.
+.P
+If we use atomic grouping for the previous example, the matcher gives up
+immediately on failing to match "foo" the first time. The notation is a kind of
+special parenthesis, starting with (?> as in this example:
+.sp
+  (?>\ed+)foo
+.sp
+Perl 5.28 introduced an experimental alphabetic form starting with (* which may
+be easier to remember:
+.sp
+  (*atomic:\ed+)foo
+.sp
+This kind of parenthesized group "locks up" the part of the pattern it contains
+once it has matched, and a failure further into the pattern is prevented from
+backtracking into it. Backtracking past it to previous items, however, works as
+normal.
+.P
+An alternative description is that a group of this type matches exactly the
+string of characters that an identical standalone pattern would match, if
+anchored at the current point in the subject string.
+.P
+Atomic groups are not capture groups. Simple cases such as the above example
+can be thought of as a maximizing repeat that must swallow everything it can.
+So, while both \ed+ and \ed+? are prepared to adjust the number of digits they
+match in order to make the rest of the pattern match, (?>\ed+) can only match
+an entire sequence of digits.
+.P
+Atomic groups in general can of course contain arbitrarily complicated
+expressions, and can be nested. However, when the contents of an atomic
+group is just a single repeated item, as in the example above, a simpler
+notation, called a "possessive quantifier" can be used. This consists of an
+additional + character following a quantifier. Using this notation, the
+previous example can be rewritten as
+.sp
+  \ed++foo
+.sp
+Note that a possessive quantifier can be used with an entire group, for
+example:
+.sp
+  (abc|xyz){2,3}+
+.sp
+Possessive quantifiers are always greedy; the setting of the PCRE2_UNGREEDY
+option is ignored. They are a convenient notation for the simpler forms of
+atomic group. However, there is no difference in the meaning of a possessive
+quantifier and the equivalent atomic group, though there may be a performance
+difference; possessive quantifiers should be slightly faster.
+.P
+The possessive quantifier syntax is an extension to the Perl 5.8 syntax.
+Jeffrey Friedl originated the idea (and the name) in the first edition of his
+book. Mike McCloskey liked it, so implemented it when he built Sun's Java
+package, and PCRE1 copied it from there. It found its way into Perl at release
+5.10.
+.P
+PCRE2 has an optimization that automatically "possessifies" certain simple
+pattern constructs. For example, the sequence A+B is treated as A++B because
+there is no point in backtracking into a sequence of A's when B must follow.
+This feature can be disabled by the PCRE2_NO_AUTOPOSSESS option, or starting
+the pattern with (*NO_AUTO_POSSESS).
+.P
+When a pattern contains an unlimited repeat inside a group that can itself be
+repeated an unlimited number of times, the use of an atomic group is the only
+way to avoid some failing matches taking a very long time indeed. The pattern
+.sp
+  (\eD+|<\ed+>)*[!?]
+.sp
+matches an unlimited number of substrings that either consist of non-digits, or
+digits enclosed in <>, followed by either ! or ?. When it matches, it runs
+quickly. However, if it is applied to
+.sp
+  aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+.sp
+it takes a long time before reporting failure. This is because the string can
+be divided between the internal \eD+ repeat and the external * repeat in a
+large number of ways, and all have to be tried. (The example uses [!?] rather
+than a single character at the end, because both PCRE2 and Perl have an
+optimization that allows for fast failure when a single character is used. They
+remember the last single character that is required for a match, and fail early
+if it is not present in the string.) If the pattern is changed so that it uses
+an atomic group, like this:
+.sp
+  ((?>\eD+)|<\ed+>)*[!?]
+.sp
+sequences of non-digits cannot be broken, and failure happens quickly.
+.
+.
+.\" HTML 
+.SH "BACKREFERENCES"
+.rs
+.sp
+Outside a character class, a backslash followed by a digit greater than 0 (and
+possibly further digits) is a backreference to a capture group earlier (that
+is, to its left) in the pattern, provided there have been that many previous
+capture groups.
+.P
+However, if the decimal number following the backslash is less than 8, it is
+always taken as a backreference, and causes an error only if there are not that
+many capture groups in the entire pattern. In other words, the group that is
+referenced need not be to the left of the reference for numbers less than 8. A
+"forward backreference" of this type can make sense when a repetition is
+involved and the group to the right has participated in an earlier iteration.
+.P
+It is not possible to have a numerical "forward backreference" to a group whose
+number is 8 or more using this syntax because a sequence such as \e50 is
+interpreted as a character defined in octal. See the subsection entitled
+"Non-printing characters"
+.\" HTML 
+.\" 
+above
+.\"
+for further details of the handling of digits following a backslash. Other
+forms of backreferencing do not suffer from this restriction. In particular,
+there is no problem when named capture groups are used (see below).
+.P
+Another way of avoiding the ambiguity inherent in the use of digits following a
+backslash is to use the \eg escape sequence. This escape must be followed by a
+signed or unsigned number, optionally enclosed in braces. These examples are
+all identical:
+.sp
+  (ring), \e1
+  (ring), \eg1
+  (ring), \eg{1}
+.sp
+An unsigned number specifies an absolute reference without the ambiguity that
+is present in the older syntax. It is also useful when literal digits follow
+the reference. A signed number is a relative reference. Consider this example:
+.sp
+  (abc(def)ghi)\eg{-1}
+.sp
+The sequence \eg{-1} is a reference to the capture group whose number is one
+less than the number of the next group to be started, so in this example (where
+the next group would be numbered 3) is it equivalent to \e2, and \eg{-2} would
+be equivalent to \e1. Note that if this construct is inside a capture group,
+that group is included in the count, so in this example \eg{-2} also refers to
+group 1:
+.sp
+  (A)(\eg{-2}B)
+.sp
+The use of relative references can be helpful in long patterns, and also in
+patterns that are created by joining together fragments that contain references
+within themselves.
+.P
+The sequence \eg{+1} is a reference to the next capture group that is started
+after this item, and \eg{+2} refers to the one after that, and so on. This kind
+of forward reference can be useful in patterns that repeat. Perl does not
+support the use of + in this way.
+.P
+A backreference matches whatever actually most recently matched the capture
+group in the current subject string, rather than anything at all that matches
+the group (see
+.\" HTML 
+.\" 
+"Groups as subroutines"
+.\"
+below for a way of doing that). So the pattern
+.sp
+  (sens|respons)e and \e1ibility
+.sp
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If caseful matching is in force at the time of the
+backreference, the case of letters is relevant. For example,
+.sp
+  ((?i)rah)\es+\e1
+.sp
+matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original
+capture group is matched caselessly.
+.P
+There are several different ways of writing backreferences to named capture
+groups. The .NET syntax is \ek{name}, the Python syntax is (?=name), and the
+original Perl syntax is \ek or \ek'name'. All of these are now supported
+by both Perl and PCRE2. Perl 5.10's unified backreference syntax, in which \eg
+can be used for both numeric and named references, is also supported by PCRE2.
+We could rewrite the above example in any of the following ways:
+.sp
+  (?(?i)rah)\es+\ek
+  (?'p1'(?i)rah)\es+\ek{p1}
+  (?P(?i)rah)\es+(?P=p1)
+  (?(?i)rah)\es+\eg{p1}
+.sp
+A capture group that is referenced by name may appear in the pattern before or
+after the reference.
+.P
+There may be more than one backreference to the same group. If a group has not
+actually been used in a particular match, backreferences to it always fail by
+default. For example, the pattern
+.sp
+  (a|(bc))\e2
+.sp
+always fails if it starts to match "a" rather than "bc". However, if the
+PCRE2_MATCH_UNSET_BACKREF option is set at compile time, a backreference to an
+unset value matches an empty string.
+.P
+Because there may be many capture groups in a pattern, all digits following a
+backslash are taken as part of a potential backreference number. If the pattern
+continues with a digit character, some delimiter must be used to terminate the
+backreference. If the PCRE2_EXTENDED or PCRE2_EXTENDED_MORE option is set, this
+can be white space. Otherwise, the \eg{} syntax or an empty comment (see
+.\" HTML 
+.\" 
+"Comments"
+.\"
+below) can be used.
+.
+.
+.SS "Recursive backreferences"
+.rs
+.sp
+A backreference that occurs inside the group to which it refers fails when the
+group is first used, so, for example, (a\e1) never matches. However, such
+references can be useful inside repeated groups. For example, the pattern
+.sp
+  (a|b\e1)+
+.sp
+matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of
+the group, the backreference matches the character string corresponding to the
+previous iteration. In order for this to work, the pattern must be such that
+the first iteration does not need to match the backreference. This can be done
+using alternation, as in the example above, or by a quantifier with a minimum
+of zero.
+.P
+For versions of PCRE2 less than 10.25, backreferences of this type used to

+.\" HTML 
+.SH ASSERTIONS
+.rs
+.sp
+An assertion is a test on the characters following or preceding the current
+matching point that does not consume any characters. The simple assertions
+coded as \eb, \eB, \eA, \eG, \eZ, \ez, ^ and $ are described
+.\" HTML 
+.\" 
+above.
+.\"
+.P
+More complicated assertions are coded as parenthesized groups. There are two
+kinds: those that look ahead of the current position in the subject string, and
+those that look behind it, and in each case an assertion may be positive (must
+match for the assertion to be true) or negative (must not match for the
+assertion to be true). An assertion group is matched in the normal way,
+and if it is true, matching continues after it, but with the matching position
+in the subject string reset to what it was before the assertion was processed.
+.P
+The Perl-compatible lookaround assertions are atomic. If an assertion is true,
+but there is a subsequent matching failure, there is no backtracking into the
+assertion. However, there are some cases where non-atomic assertions can be
+useful. PCRE2 has some support for these, described in the section entitled
+.\" HTML 
+.\" 
+"Non-atomic assertions"
+.\"
+below, but they are not Perl-compatible.
+.P
+A lookaround assertion may appear as the condition in a
+.\" HTML 
+.\" 
+conditional group
+.\"
+(see below). In this case, the result of matching the assertion determines
+which branch of the condition is followed.
+.P
+Assertion groups are not capture groups. If an assertion contains capture
+groups within it, these are counted for the purposes of numbering the capture
+groups in the whole pattern. Within each branch of an assertion, locally
+captured substrings may be referenced in the usual way. For example, a sequence
+such as (.)\eg{-1} can be used to check that two adjacent characters are the
+same.
+.P
+When a branch within an assertion fails to match, any substrings that were
+captured are discarded (as happens with any pattern branch that fails to
+match). A negative assertion is true only when all its branches fail to match;
+this means that no captured substrings are ever retained after a successful
+negative assertion. When an assertion contains a matching branch, what happens
+depends on the type of assertion.
+.P
+For a positive assertion, internally captured substrings in the successful
+branch are retained, and matching continues with the next pattern item after
+the assertion. For a negative assertion, a matching branch means that the
+assertion is not true. If such an assertion is being used as a condition in a
+.\" HTML 
+.\" 
+conditional group
+.\"
+(see below), captured substrings are retained, because matching continues with
+the "no" branch of the condition. For other failing negative assertions,
+control passes to the previous backtracking point, thus discarding any captured
+strings within the assertion.
+.P
+Most assertion groups may be repeated; though it makes no sense to assert the
+same thing several times, the side effect of capturing in positive assertions
+may occasionally be useful. However, an assertion that forms the condition for
+a conditional group may not be quantified. PCRE2 used to restrict the
+repetition of assertions, but from release 10.35 the only restriction is that
+an unlimited maximum repetition is changed to be one more than the minimum. For
+example, {3,} is treated as {3,4}.
+.
+.
+.SS "Alphabetic assertion names"
+.rs
+.sp
+Traditionally, symbolic sequences such as (?= and (?<= have been used to
+specify lookaround assertions. Perl 5.28 introduced some experimental
+alphabetic alternatives which might be easier to remember. They all start with
+(* instead of (? and must be written using lower case letters. PCRE2 supports
+the following synonyms:
+.sp
+  (*positive_lookahead:  or (*pla: is the same as (?=
+  (*negative_lookahead:  or (*nla: is the same as (?!
+  (*positive_lookbehind: or (*plb: is the same as (?<=

+.SS "Lookbehind assertions"
+.rs
+.sp
+Lookbehind assertions start with (?<= for positive assertions and (?
+.\" 
+(see above)
+.\"
+can be used instead of a lookbehind assertion at the start of a pattern to get
+round the length limit restriction.
+.P
+In UTF-8 and UTF-16 modes, PCRE2 does not allow the \eC escape (which matches a
+single code unit even in a UTF mode) to appear in lookbehind assertions,
+because it makes it impossible to calculate the length of the lookbehind. The
+\eX and \eR escapes, which can match different numbers of code units, are never
+permitted in lookbehinds.
+.P
+.\" HTML 
+.\" 
+"Subroutine"
+.\"
+calls (see below) such as (?2) or (?&X) are permitted in lookbehinds, as long
+as the called capture group matches a limited-length string. However,
+.\" HTML 
+.\" 
+recursion,
+.\"
+that is, a "subroutine" call into a group that is already active,
+is not supported.
+.P
+PCRE2 supports backreferences in lookbehinds, but only if certain conditions
+are met. The PCRE2_MATCH_UNSET_BACKREF option must not be set, there must be no
+use of (?| in the pattern (it creates duplicate group numbers), and if the
+backreference is by name, the name must be unique. Of course, the referenced
+group must itself match a limited length substring. The following pattern
+matches words containing at least two characters that begin and end with the
+same character:
+.sp
+   \eb(\ew)\ew++(?<=\e1)
+.P
+Possessive quantifiers can be used in conjunction with lookbehind assertions to
+specify efficient matching at the end of subject strings. Consider a simple
+pattern such as
+.sp
+  abcd$
+.sp
+when applied to a long string that does not match. Because matching proceeds
+from left to right, PCRE2 will look for each "a" in the subject and then see if
+what follows matches the rest of the pattern. If the pattern is specified as
+.sp
+  ^.*abcd$
+.sp
+the initial .* matches the entire string at first, but when this fails (because
+there is no following "a"), it backtracks to match all but the last character,
+then all but the last two characters, and so on. Once again the search for "a"
+covers the entire string, from right to left, so we are no better off. However,
+if the pattern is written as
+.sp
+  ^.*+(?<=abcd)
+.sp
+there can be no backtracking for the .*+ item because of the possessive
+quantifier; it can match only the entire string. The subsequent lookbehind
+assertion does a single test on the last four characters. If it fails, the
+match fails immediately. For long strings, this approach makes a significant
+difference to the processing time.
+.

+Traditional lookaround assertions are atomic. That is, if an assertion is true,
+but there is a subsequent matching failure, there is no backtracking into the
+assertion. However, there are some cases where non-atomic positive assertions
+can be useful. PCRE2 provides these using the following syntax:
+.sp
+  (*non_atomic_positive_lookahead:  or (*napla: or (?*
+  (*non_atomic_positive_lookbehind: or (*naplb: or (?<*
+.sp
+Consider the problem of finding the right-most word in a string that also
+appears earlier in the string, that is, it must appear at least twice in total.
+This pattern returns the required result as captured substring 1:
+.sp
+  ^(?x)(*napla: .* \eb(\ew++)) (?> .*? \eb\e1\eb ){2}
+.sp
+For a subject such as "word1 word2 word3 word2 word3 word4" the result is
+"word3". How does it work? At the start, ^(?x) anchors the pattern and sets the
+"x" option, which causes white space (introduced for readability) to be
+ignored. Inside the assertion, the greedy .* at first consumes the entire
+string, but then has to backtrack until the rest of the assertion can match a
+word, which is captured by group 1. In other words, when the assertion first
+succeeds, it captures the right-most word in the string.
+.P
+The current matching point is then reset to the start of the subject, and the
+rest of the pattern match checks for two occurrences of the captured word,
+using an ungreedy .*? to scan from the left. If this succeeds, we are done, but
+if the last word in the string does not occur twice, this part of the pattern
+fails. If a traditional atomic lookahead (?= or (*pla: had been used, the
+assertion could not be re-entered, and the whole match would fail. The pattern
+would succeed only if the very last word in the subject was found twice.
+.P
+Using a non-atomic lookahead, however, means that when the last word does not
+occur twice in the string, the lookahead can backtrack and find the second-last
+word, and so on, until either the match succeeds, or all words have been
+tested.
+.P
+Two conditions must be met for a non-atomic assertion to be useful: the
+contents of one or more capturing groups must change after a backtrack into the
+assertion, and there must be a backreference to a changed group later in the
+pattern. If this is not the case, the rest of the pattern match fails exactly
+as before because nothing has changed, so using a non-atomic assertion just
+wastes resources.
+.P
+There is one exception to backtracking into a non-atomic assertion. If an
+(*ACCEPT) control verb is triggered, the assertion succeeds atomically. That
+is, a subsequent match failure cannot backtrack into the assertion.
+.P
+Non-atomic assertions are not supported by the alternative matching function
+\fBpcre2_dfa_match()\fP. They are supported by JIT, but only if they do not
+contain any control verbs such as (*ACCEPT). (This may change in future). Note

+.SH "SCRIPT RUNS"
+.rs
+.sp
+In concept, a script run is a sequence of characters that are all from the same
+Unicode script such as Latin or Greek. However, because some scripts are
+commonly used together, and because some diacritical and other marks are used
+with multiple scripts, it is not that simple. There is a full description of
+the rules that PCRE2 uses in the section entitled
+.\" HTML 
+.\" 
+"Script Runs"
+.\"
+in the
+.\" HREF
+\fBpcre2unicode\fP
+.\"
+documentation.
+.P
+If part of a pattern is enclosed between (*script_run: or (*sr: and a closing
+parenthesis, it fails if the sequence of characters that it matches are not a
+script run. After a failure, normal backtracking occurs. Script runs can be
+used to detect spoofing attacks using characters that look the same, but are
+from different scripts. The string "paypal.com" is an infamous example, where
+the letters could be a mixture of Latin and Cyrillic. This pattern ensures that
+the matched characters in a sequence of non-spaces that follow white space are
+a script run:
+.sp
+  \es+(*sr:\eS+)
+.sp
+To be sure that they are all from the Latin script (for example), a lookahead
+can be used:
+.sp
+  \es+(?=\ep{Latin})(*sr:\eS+)
+.sp
+This works as long as the first character is expected to be a character in that
+script, and not (for example) punctuation, which is allowed with any script. If
+this is not the case, a more creative lookahead is needed. For example, if
+digits, underscore, and dots are permitted at the start:
+.sp
+  \es+(?=[0-9_.]*\ep{Latin})(*sr:\eS+)
+.sp
+.P
+In many cases, backtracking into a script run pattern fragment is not
+desirable. The script run can employ an atomic group to prevent this. Because
+this is a common requirement, a shorthand notation is provided by
+(*atomic_script_run: or (*asr:
+.sp
+  (*asr:...) is the same as (*sr:(?>...))
+.sp
+Note that the atomic group is inside the script run. Putting it outside would
+not prevent backtracking into the script run pattern.
+.P
+Support for script runs is not available if PCRE2 is compiled without Unicode
+support. A compile-time error is given if any of the above constructs is
+encountered. Script runs are not supported by the alternate matching function,
+\fBpcre2_dfa_match()\fP because they use the same mechanism as capturing
+parentheses.

+  (?(condition)yes-pattern)

+.sp
+If the condition is satisfied, the yes-pattern is used; otherwise the
+no-pattern (if present) is used. An absent no-pattern is equivalent to an empty
+string (it always matches). If there are more than two alternatives in the
+group, a compile-time error occurs. Each of the two alternatives may itself
+contain nested groups of any form, including conditional groups; the
+restriction to two alternatives applies only at the level of the condition
+itself. This pattern fragment is an example where the alternatives are complex:
+.sp
+  (?(1) (A|B|C) | (D | (?(2)E|F) | E) )
+.sp
+.P
+There are five kinds of condition: references to capture groups, references to
+recursion, two pseudo-conditions called DEFINE and VERSION, and assertions.
+.
+.
+.SS "Checking for a used capture group by number"
+.rs
+.sp
+If the text between the parentheses consists of a sequence of digits, the
+condition is true if a capture group of that number has previously matched. If
+there is more than one capture group with the same number (see the earlier
+.\"
+.\" HTML 
+.\" 
+section about duplicate group numbers),
+.\"
+the condition is true if any of them have matched. An alternative notation,
+which is a PCRE2 extension, not supported by Perl, is to precede the digits
+with a plus or minus sign. In this case, the group number is relative rather
+than absolute. The most recently opened capture group (which could be enclosing
+this condition) can be referenced by (?(-1), the next most recent by (?(-2),
+and so on. Inside loops it can also make sense to refer to subsequent groups.
+The next capture group to be opened can be referenced as (?(+1), and so on. The
+value zero in any of these forms is not used; it provokes a compile-time error.
+.P
+Consider the following pattern, which contains non-significant white space to
+make it more readable (assume the PCRE2_EXTENDED option) and to divide it into
+three parts for ease of discussion:
+.sp
+  ( \e( )?    [^()]+    (?(1) \e) )
+.sp
+The first part matches an optional opening parenthesis, and if that
+character is present, sets it as the first captured substring. The second part
+matches one or more characters that are not parentheses. The third part is a
+conditional group that tests whether or not the first capture group
+matched. If it did, that is, if subject started with an opening parenthesis,
+the condition is true, and so the yes-pattern is executed and a closing
+parenthesis is required. Otherwise, since no-pattern is not present, the
+conditional group matches nothing. In other words, this pattern matches a
+sequence of non-parentheses, optionally enclosed in parentheses.
+.P
+If you were embedding this pattern in a larger one, you could use a relative
+reference:
+.sp
+  ...other stuff... ( \e( )?    [^()]+    (?(-1) \e) ) ...
+.sp
+This makes the fragment independent of the parentheses in the larger pattern.
+.
+.
+.SS "Checking for a used capture group by name"

+had this facility before Perl, the syntax (?(name)...) is also recognized.
+Note, however, that undelimited names consisting of the letter R followed by
+digits are ambiguous (see the following section). Rewriting the above example
+to use a named group gives this:
+.sp
+  (? \e( )?    [^()]+    (?() \e) )
+.sp
+If the name used in a condition of this kind is a duplicate, the test is
+applied to all groups of the same name, and is true if any one of them has
+matched.
+.
+.
+.SS "Checking for pattern recursion"

+"Recursion" in this sense refers to any subroutine-like call from one part of

+If a condition is the string (R), and there is no capture group with the name
+R, the condition is true if matching is currently in a recursion or subroutine
+call to the whole pattern or any capture group. If digits follow the letter R,

+call is into a group with the given number, which must exist somewhere in the
+overall pattern. This is a contrived example that is equivalent to a+b:
+.sp
+  ((?(R1)a+|(?1)b))
+.sp
+However, in both cases, if there is a capture group with a matching name, the
+condition tests for its being set, as described in the section above, instead
+of testing for recursion. For example, creating a group with the name R1 by
+adding (?) to the above pattern completely changes its meaning.
+.P
+If a name preceded by ampersand follows the letter R, for example:
+.sp
+  (?(R&name)...)
+.sp
+the condition is true if the most recent recursion is into a group of that name
+(which must exist within the pattern).
+.P
+This condition does not check the entire recursion stack. It tests only the
+current level. If the name used in a condition of this kind is a duplicate, the

+used to define subroutines that can be referenced from elsewhere. (The use of

+  \eb (?&byte) (\e.(?&byte)){3} \eb

+The first part of the pattern is a DEFINE group inside which another group
+named "byte" is defined. This matches an individual component of an IPv4
+address (a number less than 256). When matching takes place, this part of the
+pattern is skipped because DEFINE acts like a false condition. The rest of the

+Programs that link with a PCRE2 library can check the version by calling

+  (?(VERSION>=10.4)yes|no)
+.sp
+This pattern matches "yes" if the PCRE2 version is greater or equal to 10.4, or
+"no" otherwise. The fractional part of the version number may not contain more
+than two digits.
+.
+.
+.SS "Assertion conditions"
+.rs
+.sp
+If the condition is not in any of the above formats, it must be a parenthesized
+assertion. This may be a positive or negative lookahead or lookbehind
+assertion. However, it must be a traditional atomic assertion, not one of the
+.\" HTML 
+.\" 
+non-atomic assertions.
+.\"
+.P
+Consider this pattern, again containing non-significant white space, and with
+the two alternatives on the second line:
+.sp
+  (?(?=[^a-z]*[a-z])
+  \ed{2}-[a-z]{3}-\ed{2}  |  \ed{2}-\ed{2}-\ed{2} )
+.sp
+The condition is a positive lookahead assertion that matches an optional
+sequence of non-letters followed by a letter. In other words, it tests for the
+presence of at least one letter in the subject. If a letter is found, the
+subject is matched against the first alternative; otherwise it is matched
+against the second. This pattern matches strings in one of the two forms
+dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits.
+.P
+When an assertion that is a condition contains capture groups, any
+capturing that occurs in a matching branch is retained afterwards, for both
+positive and negative assertions, because matching always continues after the
+assertion, whether it succeeds or fails. (Compare non-conditional assertions,
+for which captures are retained only for positive assertions that succeed.)
+.
+.
+.\" HTML 
+.SH COMMENTS
+.rs
+.sp
+There are two ways of including comments in patterns that are processed by
+PCRE2. In both cases, the start of the comment must not be in a character
+class, nor in the middle of any other sequence of related characters such as
+(?: or a group name or number. The characters that make up a comment play
+no part in the pattern matching.
+.P
+The sequence (?# marks the start of a comment that continues up to the next
+closing parenthesis. Nested parentheses are not permitted. If the
+PCRE2_EXTENDED or PCRE2_EXTENDED_MORE option is set, an unescaped # character
+also introduces a comment, which in this case continues to immediately after
+the next newline character or character sequence in the pattern. Which
+characters are interpreted as newlines is controlled by an option passed to the
+compiling function or by a special sequence at the start of the pattern, as
+described in the section entitled
+.\" HTML 
+.\" 
+"Newline conventions"
+.\"
+above. Note that the end of this type of comment is a literal newline sequence
+in the pattern; escape sequences that happen to represent a newline do not
+count. For example, consider this pattern when PCRE2_EXTENDED is set, and the
+default newline convention (a single linefeed character) is in force:
+.sp
+  abc #comment \en still comment
+.sp
+On encountering the # character, \fBpcre2_compile()\fP skips along, looking for
+a newline in the pattern. The sequence \en is still literal at this stage, so
+it does not terminate the comment. Only an actual character with the code value
+0x0a (the default newline) does so.

+.\" HTML 
+.SH "RECURSIVE PATTERNS"
+.rs
+.sp
+Consider the problem of matching a string in parentheses, allowing for
+unlimited nested parentheses. Without the use of recursion, the best that can
+be done is to use a pattern that matches up to some fixed depth of nesting. It
+is not possible to handle an arbitrary nesting depth.
+.P
+For some time, Perl has provided a facility that allows regular expressions to
+recurse (amongst other things). It does this by interpolating Perl code in the
+expression at run time, and the code can refer to the expression itself. A Perl
+pattern using code interpolation to solve the parentheses problem can be
+created like this:
+.sp
+  $re = qr{\e( (?: (?>[^()]+) | (?p{$re}) )* \e)}x;
+.sp
+The (?p{...}) item interpolates Perl code at run time, and in this case refers
+recursively to the pattern in which it appears.
+.P
+Obviously, PCRE2 cannot support the interpolation of Perl code. Instead, it
+supports special syntax for recursion of the entire pattern, and also for
+individual capture group recursion. After its introduction in PCRE1 and Python,
+this kind of recursion was subsequently introduced into Perl at release 5.10.
+.P
+A special item that consists of (? followed by a number greater than zero and a
+closing parenthesis is a recursive subroutine call of the capture group of the
+given number, provided that it occurs inside that group. (If not, it is a
+.\" HTML 
+.\" 
+non-recursive subroutine
+.\"
+call, which is described in the next section.) The special item (?R) or (?0) is
+a recursive call of the entire regular expression.
+.P
+This PCRE2 pattern solves the nested parentheses problem (assume the
+PCRE2_EXTENDED option is set so that white space is ignored):
+.sp
+  \e( ( [^()]++ | (?R) )* \e)
+.sp
+First it matches an opening parenthesis. Then it matches any number of
+substrings which can either be a sequence of non-parentheses, or a recursive
+match of the pattern itself (that is, a correctly parenthesized substring).
+Finally there is a closing parenthesis. Note the use of a possessive quantifier
+to avoid backtracking into sequences of non-parentheses.
+.P
+If this were part of a larger pattern, you would not want to recurse the entire
+pattern, so instead you could use this:
+.sp
+  ( \e( ( [^()]++ | (?1) )* \e) )
+.sp
+We have put the pattern into parentheses, and caused the recursion to refer to
+them instead of the whole pattern.
+.P
+In a larger pattern, keeping track of parenthesis numbers can be tricky. This
+is made easier by the use of relative references. Instead of (?1) in the
+pattern above you can write (?-2) to refer to the second most recently opened
+parentheses preceding the recursion. In other words, a negative number counts
+capturing parentheses leftwards from the point at which it is encountered.
+.P
+Be aware however, that if
+.\" HTML 
+.\" 
+duplicate capture group numbers
+.\"
+are in use, relative references refer to the earliest group with the
+appropriate number. Consider, for example:
+.sp
+  (?|(a)|(b)) (c) (?-2)
+.sp
+The first two capture groups (a) and (b) are both numbered 1, and group (c)
+is number 2. When the reference (?-2) is encountered, the second most recently
+opened parentheses has the number 1, but it is the first such group (the (a)
+group) to which the recursion refers. This would be the same if an absolute
+reference (?1) was used. In other words, relative references are just a
+shorthand for computing a group number.
+.P
+It is also possible to refer to subsequent capture groups, by writing
+references such as (?+2). However, these cannot be recursive because the
+reference is not inside the parentheses that are referenced. They are always
+.\" HTML 
+.\" 
+non-recursive subroutine
+.\"
+calls, as described in the next section.
+.P
+An alternative approach is to use named parentheses. The Perl syntax for this
+is (?&name); PCRE1's earlier syntax (?P>name) is also supported. We could
+rewrite the above example as follows:
+.sp
+  (? \e( ( [^()]++ | (?&pn) )* \e) )
+.sp
+If there is more than one group with the same name, the earliest one is
+used.
+.P
+The example pattern that we have been looking at contains nested unlimited
+repeats, and so the use of a possessive quantifier for matching strings of
+non-parentheses is important when applying the pattern to strings that do not
+match. For example, when this pattern is applied to
+.sp
+  (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+.sp
+it yields "no match" quickly. However, if a possessive quantifier is not used,
+the match runs for a very long time indeed because there are so many different
+ways the + and * repeats can carve up the subject, and all have to be tested
+before failure can be reported.
+.P
+At the end of a match, the values of capturing parentheses are those from
+the outermost level. If you want to obtain intermediate values, a callout
+function can be used (see below and the
+.\" HREF
+\fBpcre2callout\fP
+.\"
+documentation). If the pattern above is matched against
+.sp
+  (ab(cd)ef)
+.sp
+the value for the inner capturing parentheses (numbered 2) is "ef", which is
+the last value taken on at the top level. If a capture group is not matched at
+the top level, its final captured value is unset, even if it was (temporarily)
+set at a deeper level during the matching process.
+.P
+Do not confuse the (?R) item with the condition (R), which tests for recursion.
+Consider this pattern, which matches text in angle brackets, allowing for
+arbitrary nesting. Only digits are allowed in nested brackets (that is, when
+recursing), whereas any characters are permitted at the outer level.
+.sp
+  < (?: (?(R) \ed++  | [^<>]*+) | (?R)) * >
+.sp
+In this pattern, (?(R) is the start of a conditional group, with two different
+alternatives for the recursive and non-recursive cases. The (?R) item is the
+actual recursive call.
+.
+.
+.\" HTML 
+.SS "Differences in recursion processing between PCRE2 and Perl"
+.rs
+.sp
+Some former differences between PCRE2 and Perl no longer exist.
+.P
+Before release 10.30, recursion processing in PCRE2 differed from Perl in that
+a recursive subroutine call was always treated as an atomic group. That is,
+once it had matched some of the subject string, it was never re-entered, even
+if it contained untried alternatives and there was a subsequent matching
+failure. (Historical note: PCRE implemented recursion before Perl did.)
+.P
+Starting with release 10.30, recursive subroutine calls are no longer treated
+as atomic. That is, they can be re-entered to try unused alternatives if there
+is a matching failure later in the pattern. This is now compatible with the way
+Perl works. If you want a subroutine call to be atomic, you must explicitly
+enclose it in an atomic group.
+.P
+Supporting backtracking into recursions simplifies certain types of recursive
+pattern. For example, this pattern matches palindromic strings:
+.sp
+  ^((.)(?1)\e2|.?)$
+.sp
+The second branch in the group matches a single central character in the
+palindrome when there are an odd number of characters, or nothing when there
+are an even number of characters, but in order to work it has to be able to try
+the second case when the rest of the pattern match fails. If you want to match
+typical palindromic phrases, the pattern has to ignore all non-word characters,
+which can be done like this:
+.sp
+  ^\eW*+((.)\eW*+(?1)\eW*+\e2|\eW*+.?)\eW*+$
+.sp
+If run with the PCRE2_CASELESS option, this pattern matches phrases such as "A
+man, a plan, a canal: Panama!". Note the use of the possessive quantifier *+ to
+avoid backtracking into sequences of non-word characters. Without this, PCRE2
+takes a great deal longer (ten times or more) to match typical phrases, and
+Perl takes so long that you think it has gone into a loop.
+.P
+Another way in which PCRE2 and Perl used to differ in their recursion
+processing is in the handling of captured values. Formerly in Perl, when a
+group was called recursively or as a subroutine (see the next section), it
+had no access to any values that were captured outside the recursion, whereas
+in PCRE2 these values can be referenced. Consider this pattern:
+.sp
+  ^(.)(\e1|a(?2))
+.sp
+This pattern matches "bab". The first capturing parentheses match "b", then in
+the second group, when the backreference \e1 fails to match "b", the second
+alternative matches "a" and then recurses. In the recursion, \e1 does now match
+"b" and so the whole match succeeds. This match used to fail in Perl, but in
+later versions (I tried 5.024) it now works.
+.
+.
+.\" HTML 
+.SH "GROUPS AS SUBROUTINES"
+.rs
+.sp
+If the syntax for a recursive group call (either by number or by name) is used
+outside the parentheses to which it refers, it operates a bit like a subroutine
+in a programming language. More accurately, PCRE2 treats the referenced group
+as an independent subpattern which it tries to match at the current matching
+position. The called group may be defined before or after the reference. A
+numbered reference can be absolute or relative, as in these examples:
+.sp
+  (...(absolute)...)...(?2)...
+  (...(relative)...)...(?-1)...
+  (...(?+1)...(relative)...
+.sp
+An earlier example pointed out that the pattern
+.sp
+  (sens|respons)e and \e1ibility
+.sp
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If instead the pattern
+.sp
+  (sens|respons)e and (?1)ibility
+.sp
+is used, it does match "sense and responsibility" as well as the other two
+strings. Another example is given in the discussion of DEFINE above.
+.P
+Like recursions, subroutine calls used to be treated as atomic, but this
+changed at PCRE2 release 10.30, so backtracking into subroutine calls can now
+occur. However, any capturing parentheses that are set during the subroutine
+call revert to their previous values afterwards.
+.P
+Processing options such as case-independence are fixed when a group is
+defined, so if it is used as a subroutine, such options cannot be changed for
+different calls. For example, consider this pattern:
+.sp
+  (abc)(?i:(?-1))
+.sp
+It matches "abcabc". It does not match "abcABC" because the change of
+processing option does not affect the called group.

+.SH CALLOUTS
+.rs
+.sp
+Perl has a feature whereby using the sequence (?{...}) causes arbitrary Perl
+code to be obeyed in the middle of matching a regular expression. This makes it
+possible, amongst other things, to extract different substrings that match the
+same pair of parentheses when there is a repetition.
+.P
+PCRE2 provides a similar feature, but of course it cannot obey arbitrary Perl
+code. The feature is called "callout". The caller of PCRE2 provides an external
+function by putting its entry point in a match context using the function
+\fBpcre2_set_callout()\fP, and then passing that context to \fBpcre2_match()\fP
+or \fBpcre2_dfa_match()\fP. If no match context is passed, or if the callout
+entry point is set to NULL, callouts are disabled.
+.P
+Within a regular expression, (?C) indicates a point at which the external
+function is to be called. There are two kinds of callout: those with a
+numerical argument and those with a string argument. (?C) on its own with no
+argument is treated as (?C0). A numerical argument allows the application to
+distinguish between different callouts. String arguments were added for release
+10.20 to make it possible for script languages that use PCRE2 to embed short
+scripts within patterns in a similar way to Perl.
+.P
+During matching, when PCRE2 reaches a callout point, the external function is
+called. It is provided with the number or string argument of the callout, the
+position in the pattern, and one item of data that is also set in the match
+block. The callout function may cause matching to proceed, to backtrack, or to
+fail.
+.P
+By default, PCRE2 implements a number of optimizations at matching time, and
+one side-effect is that sometimes callouts are skipped. If you need all
+possible callouts to happen, you need to set options that disable the relevant
+optimizations. More details, including a complete description of the
+programming interface to the callout function, are given in the
+.\" HREF

+documentation.
+.
+.
+.SS "Callouts with numerical arguments"

+If you just want to have a means of identifying different callout points, put a

+callout points:
+.sp
+  (?C1)abc(?C2)def
+.sp
+If the PCRE2_AUTO_CALLOUT flag is passed to \fBpcre2_compile()\fP, numerical
+callouts are automatically installed before each item in the pattern. They are
+all numbered 255. If there is a conditional group in the pattern whose
+condition is an assertion, an additional callout is inserted just before the
+condition. An explicit callout may also be set at this position, as in this
+example:
+.sp
+  (?(?C9)(?=a)abc|def)
+.sp
+Note that this applies only to assertion conditions, not to other types of
+condition.

+A delimited string may be used instead of a number as a callout argument. The
+starting delimiter must be one of ` ' " ^ % # $ { and the ending delimiter is

+.SH "BACKTRACKING CONTROL"
+.rs
+.sp
+There are a number of special "Backtracking Control Verbs" (to use Perl's
+terminology) that modify the behaviour of backtracking during matching. They
+are generally of the form (*VERB) or (*VERB:NAME). Some verbs take either form,
+and may behave differently depending on whether or not a name argument is
+present. The names are not required to be unique within the pattern.
+.P
+By default, for compatibility with Perl, a name is any sequence of characters
+that does not include a closing parenthesis. The name is not processed in
+any way, and it is not possible to include a closing parenthesis in the name.
+This can be changed by setting the PCRE2_ALT_VERBNAMES option, but the result
+is no longer Perl-compatible.
+.P
+When PCRE2_ALT_VERBNAMES is set, backslash processing is applied to verb names
+and only an unescaped closing parenthesis terminates the name. However, the
+only backslash items that are permitted are \eQ, \eE, and sequences such as
+\ex{100} that define character code points. Character type escapes such as \ed
+are faulted.
+.P
+A closing parenthesis can be included in a name either as \e) or between \eQ
+and \eE. In addition to backslash processing, if the PCRE2_EXTENDED or
+PCRE2_EXTENDED_MORE option is also set, unescaped whitespace in verb names is
+skipped, and #-comments are recognized, exactly as in the rest of the pattern.
+PCRE2_EXTENDED and PCRE2_EXTENDED_MORE do not affect verb names unless
+PCRE2_ALT_VERBNAMES is also set.
+.P
+The maximum length of a name is 255 in the 8-bit library and 65535 in the
+16-bit and 32-bit libraries. If the name is empty, that is, if the closing
+parenthesis immediately follows the colon, the effect is as if the colon were
+not there. Any number of these verbs may occur in a pattern. Except for
+(*ACCEPT), they may not be quantified.
+.P
+Since these verbs are specifically related to backtracking, most of them can be
+used only when the pattern is to be matched using the traditional matching
+function, because that uses a backtracking algorithm. With the exception of
+(*FAIL), which behaves like a failing negative assertion, the backtracking

+The following verbs act as soon as they are encountered.

+   (*ACCEPT) or (*ACCEPT:NAME)
+.sp
+This verb causes the match to end successfully, skipping the remainder of the

+subroutine, only that group is ended successfully. Matching then continues
+at the outer level. If (*ACCEPT) in triggered in a positive assertion, the

+.P
+If (*ACCEPT) is inside capturing parentheses, the data so far is captured. For

+This matches "AB", "AAD", or "ACD"; when it matches "AB", "B" is captured by

+  (A(*ACCEPT)??B)C
+.sp
+where A, B, and C may be complex expressions. After matching "A", the matcher
+processes "BC"; if that fails, causing a backtrack, (*ACCEPT) is triggered and

+"succeed on backtrack".
+.P
+\fBWarning:\fP (*ACCEPT) should not be used within a script run group, because
+it causes an immediate exit from the group, bypassing the script run checking.
+.sp
+  (*FAIL) or (*FAIL:NAME)
+.sp
+This verb causes a matching failure, forcing backtracking to occur. It may be
+abbreviated to (*F). It is equivalent to (?!) but easier to read. The Perl
+documentation notes that it is probably useful only when combined with (?{}) or
+(??{}). Those are, of course, Perl features that are not present in PCRE2. The
+nearest equivalent is the callout feature, as for example in this pattern:
+.sp
+  a+(?C)(*FAIL)
+.sp
+A match with the string "aaaa" always fails, but the callout is taken before
+each backtrack happens (in this example, 10 times).
+.P
+(*ACCEPT:NAME) and (*FAIL:NAME) behave the same as (*MARK:NAME)(*ACCEPT) and
+(*MARK:NAME)(*FAIL), respectively, that is, a (*MARK) is recorded just before

+.
+.
+.SS "Recording which path was taken"
+.rs
+.sp
+There is one verb whose main purpose is to track how a match was arrived at,
+though it also has a secondary use in conjunction with advancing the match
+starting point (see (*SKIP) below).
+.sp
+  (*MARK:NAME) or (*:NAME)
+.sp
+A name is always required with this verb. For all the other backtracking
+control verbs, a NAME argument is optional.
+.P
+When a match succeeds, the name of the last-encountered mark name on the
+matching path is passed back to the caller as described in the section entitled

+differences in those cases when (*MARK) is used in conjunction with (*SKIP) as
+described below.
+.P
+The mark name that was last encountered on the matching path is passed back. A
+verb without a NAME argument is ignored for this purpose. Here is an example of
+\fBpcre2test\fP output, where the "mark" modifier requests the retrieval and
+outputting of (*MARK) data:
+.sp
+    re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+  data> XY
+   0: XY
+  MK: A
+  XZ
+   0: XZ
+  MK: B
+.sp
+The (*MARK) name is tagged with "MK:" in this output, and in this example it
+indicates which of the two alternatives matched. This is a more efficient way
+of obtaining this information than putting each alternative in its own
+capturing parentheses.
+.P
+If a verb with a name is encountered in a positive assertion that is true, the
+name is recorded and passed back if it is the last-encountered. This does not
+happen for negative assertions or failing positive assertions.
+.P
+After a partial match or a failed match, the last encountered name in the
+entire match process is returned. For example:
+.sp
+    re> /X(*MARK:A)Y|X(*MARK:B)Z/mark
+  data> XP
+  No match, mark = B
+.sp
+Note that in this unanchored example the mark is retained from the match
+attempt that started at the letter "X" in the subject. Subsequent match
+attempts starting at "P" and then with an empty string do not get as far as the
+(*MARK) item, but nevertheless do not reset it.
+.P
+If you are interested in (*MARK) values after failed matches, you should

+.SS "Verbs that act after backtracking"
+.rs
+.sp
+The following verbs do nothing when they are encountered. Matching continues
+with what follows, but if there is a subsequent match failure, causing a
+backtrack to the verb, a failure is forced. That is, backtracking cannot pass
+to the left of the verb. However, when one of these verbs appears inside an
+atomic group or in a lookaround assertion that is true, its effect is confined
+to that group, because once the group has been matched, there is never any
+backtracking into it. Backtracking from beyond an assertion or an atomic group
+ignores the entire group, and seeks a preceding backtracking point.
+.P
+These verbs differ in exactly what kind of failure occurs when backtracking
+reaches them. The behaviour described below is what happens when the verb is
+not in a subroutine or an assertion. Subsequent sections cover these special
+cases.
+.sp
+  (*COMMIT) or (*COMMIT:NAME)
+.sp
+This verb causes the whole match to fail outright if there is a later matching
+failure that causes backtracking to reach it. Even if the pattern is
+unanchored, no further attempts to find a match by advancing the starting point
+take place. If (*COMMIT) is the only backtracking verb that is encountered,
+once it has been passed \fBpcre2_match()\fP is committed to finding a match at
+the current starting point, or not at all. For example:
+.sp
+  a+(*COMMIT)b
+.sp
+This matches "xxaab" but not "aacaab". It can be thought of as a kind of
+dynamic anchor, or "I've started, so I must finish."
+.P
+The behaviour of (*COMMIT:NAME) is not the same as (*MARK:NAME)(*COMMIT). It is
+like (*MARK:NAME) in that the name is remembered for passing back to the
+caller. However, (*SKIP:NAME) searches only for names that are set with
+(*MARK), ignoring those set by any of the other backtracking verbs.
+.P
+If there is more than one backtracking verb in a pattern, a different one that
+follows (*COMMIT) may be triggered first, so merely passing (*COMMIT) during a
+match does not always guarantee that a match must be at this starting point.
+.P
+Note that (*COMMIT) at the start of a pattern is not the same as an anchor,
+unless PCRE2's start-of-match optimizations are turned off, as shown in this
+output from \fBpcre2test\fP:
+.sp
+    re> /(*COMMIT)abc/
+  data> xyzabc
+   0: abc
+  data>
+  re> /(*COMMIT)abc/no_start_optimize
+  data> xyzabc
+  No match
+.sp
+For the first pattern, PCRE2 knows that any match must start with "a", so the
+optimization skips along the subject to "a" before applying the pattern to the
+first set of data. The match attempt then succeeds. The second pattern disables
+the optimization that skips along to the first character. The pattern is now
+applied starting at "x", and so the (*COMMIT) causes the match to fail without
+trying any other starting points.
+.sp
+  (*PRUNE) or (*PRUNE:NAME)
+.sp
+This verb causes the match to fail at the current starting position in the
+subject if there is a later matching failure that causes backtracking to reach
+it. If the pattern is unanchored, the normal "bumpalong" advance to the next
+starting character then happens. Backtracking can occur as usual to the left of
+(*PRUNE), before it is reached, or when matching to the right of (*PRUNE), but
+if there is no match to the right, backtracking cannot cross (*PRUNE). In
+simple cases, the use of (*PRUNE) is just an alternative to an atomic group or
+possessive quantifier, but there are some uses of (*PRUNE) that cannot be
+expressed in any other way. In an anchored pattern (*PRUNE) has the same effect
+as (*COMMIT).
+.P
+The behaviour of (*PRUNE:NAME) is not the same as (*MARK:NAME)(*PRUNE). It is
+like (*MARK:NAME) in that the name is remembered for passing back to the
+caller. However, (*SKIP:NAME) searches only for names set with (*MARK),
+ignoring those set by other backtracking verbs.
+.sp
+  (*SKIP)
+.sp
+This verb, when given without a name, is like (*PRUNE), except that if the
+pattern is unanchored, the "bumpalong" advance is not to the next character,
+but to the position in the subject where (*SKIP) was encountered. (*SKIP)
+signifies that whatever text was matched leading up to it cannot be part of a
+successful match if there is a later mismatch. Consider:
+.sp
+  a+(*SKIP)b
+.sp
+If the subject is "aaaac...", after the first match attempt fails (starting at
+the first character in the string), the starting point skips on to start the
+next attempt at "c". Note that a possessive quantifier does not have the same
+effect as this example; although it would suppress backtracking during the
+first match attempt, the second attempt would start at the second character
+instead of skipping on to "c".
+.P
+If (*SKIP) is used to specify a new starting position that is the same as the
+starting position of the current match, or (by being inside a lookbehind)
+earlier, the position specified by (*SKIP) is ignored, and instead the normal
+"bumpalong" occurs.
+.sp
+  (*SKIP:NAME)
+.sp
+When (*SKIP) has an associated name, its behaviour is modified. When such a
+(*SKIP) is triggered, the previous path through the pattern is searched for the
+most recent (*MARK) that has the same name. If one is found, the "bumpalong"
+advance is to the subject position that corresponds to that (*MARK) instead of
+to where (*SKIP) was encountered. If no (*MARK) with a matching name is found,
+the (*SKIP) is ignored.
+.P
+The search for a (*MARK) name uses the normal backtracking mechanism, which
+means that it does not see (*MARK) settings that are inside atomic groups or
+assertions, because they are never re-entered by backtracking. Compare the
+following \fBpcre2test\fP examples:
+.sp
+    re> /a(?>(*MARK:X))(*SKIP:X)(*F)|(.)/
+  data: abc
+   0: a
+   1: a
+  data:
+    re> /a(?:(*MARK:X))(*SKIP:X)(*F)|(.)/
+  data: abc
+   0: b
+   1: b
+.sp
+In the first example, the (*MARK) setting is in an atomic group, so it is not
+seen when (*SKIP:X) triggers, causing the (*SKIP) to be ignored. This allows
+the second branch of the pattern to be tried at the first character position.
+In the second example, the (*MARK) setting is not in an atomic group. This
+allows (*SKIP:X) to find the (*MARK) when it backtracks, and this causes a new
+matching attempt to start at the second character. This time, the (*MARK) is
+never seen because "a" does not match "b", so the matcher immediately jumps to
+the second branch of the pattern.
+.P
+Note that (*SKIP:NAME) searches only for names set by (*MARK:NAME). It ignores
+names that are set by other backtracking verbs.
+.sp
+  (*THEN) or (*THEN:NAME)
+.sp
+This verb causes a skip to the next innermost alternative when backtracking
+reaches it. That is, it cancels any further backtracking within the current
+alternative. Its name comes from the observation that it can be used for a
+pattern-based if-then-else block:
+.sp
+  ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+.sp
+If the COND1 pattern matches, FOO is tried (and possibly further items after
+the end of the group if FOO succeeds); on failure, the matcher skips to the
+second alternative and tries COND2, without backtracking into COND1. If that
+succeeds and BAR fails, COND3 is tried. If subsequently BAZ fails, there are no
+more alternatives, so there is a backtrack to whatever came before the entire
+group. If (*THEN) is not inside an alternation, it acts like (*PRUNE).
+.P
+The behaviour of (*THEN:NAME) is not the same as (*MARK:NAME)(*THEN). It is
+like (*MARK:NAME) in that the name is remembered for passing back to the
+caller. However, (*SKIP:NAME) searches only for names set with (*MARK),
+ignoring those set by other backtracking verbs.
+.P
+A group that does not contain a | character is just a part of the enclosing
+alternative; it is not a nested alternation with only one alternative. The
+effect of (*THEN) extends beyond such a group to the enclosing alternative.
+Consider this pattern, where A, B, etc. are complex pattern fragments that do
+not contain any | characters at this level:
+.sp
+  A (B(*THEN)C) | D
+.sp
+If A and B are matched, but there is a failure in C, matching does not
+backtrack into A; instead it moves to the next alternative, that is, D.
+However, if the group containing (*THEN) is given an alternative, it
+behaves differently:
+.sp
+  A (B(*THEN)C | (*FAIL)) | D
+.sp
+The effect of (*THEN) is now confined to the inner group. After a failure in C,
+matching moves to (*FAIL), which causes the whole group to fail because there
+are no more alternatives to try. In this case, matching does backtrack into A.
+.P
+Note that a conditional group is not considered as having two alternatives,
+because only one is ever used. In other words, the | character in a conditional
+group has a different meaning. Ignoring white space, consider:
+.sp
+  ^.*? (?(?=a) a | b(*THEN)c )
+.sp
+If the subject is "ba", this pattern does not match. Because .*? is ungreedy,
+it initially matches zero characters. The condition (?=a) then fails, the
+character "b" is matched, but "c" is not. At this point, matching does not
+backtrack to .*? as might perhaps be expected from the presence of the |
+character. The conditional group is part of the single alternative that
+comprises the whole pattern, and so the match fails. (If there was a backtrack
+into .*?, allowing it to match "b", the match would succeed.)
+.P
+The verbs just described provide four different "strengths" of control when
+subsequent matching fails. (*THEN) is the weakest, carrying on the match at the
+next alternative. (*PRUNE) comes next, failing the match at the current
+starting position, but allowing an advance to the next character (for an
+unanchored pattern). (*SKIP) is similar, except that the advance may be more
+than one character. (*COMMIT) is the strongest, causing the entire match to
+fail.
+.
+.
+.SS "More than one backtracking verb"
+.rs
+.sp
+If more than one backtracking verb is present in a pattern, the one that is
+backtracked onto first acts. For example, consider this pattern, where A, B,
+etc. are complex pattern fragments:
+.sp
+  (A(*COMMIT)B(*THEN)C|ABD)
+.sp
+If A matches but B fails, the backtrack to (*COMMIT) causes the entire match to
+fail. However, if A and B match, but C fails, the backtrack to (*THEN) causes
+the next alternative (ABD) to be tried. This behaviour is consistent, but is
+not always the same as Perl's. It means that if two or more backtracking verbs
+appear in succession, all but the last of them has no effect. Consider this
+example:
+.sp
+  ...(*COMMIT)(*PRUNE)...
+.sp
+If there is a matching failure to the right, backtracking onto (*PRUNE) causes
+it to be triggered, and its action is taken. There can never be a backtrack
+onto (*COMMIT).
+.
+.
+.\" HTML 
+.SS "Backtracking verbs in repeated groups"
+.rs
+.sp
+PCRE2 sometimes differs from Perl in its handling of backtracking verbs in
+repeated groups. For example, consider:
+.sp
+  /(a(*COMMIT)b)+ac/
+.sp
+If the subject is "abac", Perl matches unless its optimizations are disabled,
+but PCRE2 always fails because the (*COMMIT) in the second repeat of the group
+acts.
+.
+.
+.\" HTML 
+.SS "Backtracking verbs in assertions"
+.rs
+.sp
+(*FAIL) in any assertion has its normal effect: it forces an immediate
+backtrack. The behaviour of the other backtracking verbs depends on whether or
+not the assertion is standalone or acting as the condition in a conditional
+group.
+.P
+(*ACCEPT) in a standalone positive assertion causes the assertion to succeed
+without any further processing; captured strings and a mark name (if set) are
+retained. In a standalone negative assertion, (*ACCEPT) causes the assertion to
+fail without any further processing; captured substrings and any mark name are
+discarded.
+.P
+If the assertion is a condition, (*ACCEPT) causes the condition to be true for
+a positive assertion and false for a negative one; captured substrings are
+retained in both cases.
+.P
+The remaining verbs act only when a later failure causes a backtrack to
+reach them. This means that, for the Perl-compatible assertions, their effect
+is confined to the assertion, because Perl lookaround assertions are atomic. A
+backtrack that occurs after such an assertion is complete does not jump back
+into the assertion. Note in particular that a (*MARK) name that is set in an
+assertion is not "seen" by an instance of (*SKIP:NAME) later in the pattern.
+.P
+PCRE2 now supports non-atomic positive assertions, as described in the section
+entitled
+.\" HTML 
+.\" 
+"Non-atomic assertions"
+.\"
+above. These assertions must be standalone (not used as conditions). They are
+not Perl-compatible. For these assertions, a later backtrack does jump back
+into the assertion, and therefore verbs such as (*COMMIT) can be triggered by
+backtracks from later in the pattern.
+.P
+The effect of (*THEN) is not allowed to escape beyond an assertion. If there
+are no more branches to try, (*THEN) causes a positive assertion to be false,
+and a negative assertion to be true.
+.P
+The other backtracking verbs are not treated specially if they appear in a
+standalone positive assertion. In a conditional positive assertion,
+backtracking (from within the assertion) into (*COMMIT), (*SKIP), or (*PRUNE)
+causes the condition to be false. However, for both standalone and conditional
+negative assertions, backtracking into (*COMMIT), (*SKIP), or (*PRUNE) causes
+the assertion to be true, without considering any further alternative branches.
+.
+.
+.\" HTML 
+.SS "Backtracking verbs in subroutines"
+.rs
+.sp
+These behaviours occur whether or not the group is called recursively.
+.P
+(*ACCEPT) in a group called as a subroutine causes the subroutine match to
+succeed without any further processing. Matching then continues after the
+subroutine call. Perl documents this behaviour. Perl's treatment of the other
+verbs in subroutines is different in some cases.
+.P
+(*FAIL) in a group called as a subroutine has its normal effect: it forces
+an immediate backtrack.
+.P
+(*COMMIT), (*SKIP), and (*PRUNE) cause the subroutine match to fail when
+triggered by being backtracked to in a group called as a subroutine. There is
+then a backtrack at the outer level.
+.P
+(*THEN), when triggered, skips to the next alternative in the innermost
+enclosing group that has alternatives (its normal behaviour). However, if there
+is no such group within the subroutine's group, the subroutine match fails and
+there is a backtrack at the outer level.

+.TH PCRE2PERFORM 3 "27 July 2022" "PCRE2 10.41"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 PERFORMANCE"
+.rs
+.sp
+Two aspects of performance are discussed below: memory usage and processing
+time. The way you express your pattern as a regular expression can affect both
+of them.
+.
+.SH "COMPILED PATTERN MEMORY USAGE"
+.rs
+.sp
+Patterns are compiled by PCRE2 into a reasonably efficient interpretive code,
+so that most simple patterns do not use much memory for storing the compiled
+version. However, there is one case where the memory usage of a compiled
+pattern can be unexpectedly large. If a parenthesized group has a quantifier
+with a minimum greater than 1 and/or a limited maximum, the whole group is
+repeated in the compiled code. For example, the pattern
+.sp
+  (abc|def){2,4}
+.sp
+is compiled as if it were
+.sp
+  (abc|def)(abc|def)((abc|def)(abc|def)?)?
+.sp
+(Technical aside: It is done this way so that backtrack points within each of
+the repetitions can be independently maintained.)
+.P
+For regular expressions whose quantifiers use only small numbers, this is not
+usually a problem. However, if the numbers are large, and particularly if such
+repetitions are nested, the memory usage can become an embarrassment. For
+example, the very simple pattern
+.sp
+  ((ab){1,1000}c){1,3}
+.sp
+uses over 50KiB when compiled using the 8-bit library. When PCRE2 is
+compiled with its default internal pointer size of two bytes, the size limit on
+a compiled pattern is 65535 code units in the 8-bit and 16-bit libraries, and
+this is reached with the above pattern if the outer repetition is increased
+from 3 to 4. PCRE2 can be compiled to use larger internal pointers and thus
+handle larger compiled patterns, but it is better to try to rewrite your
+pattern to use less memory if you can.
+.P
+One way of reducing the memory usage for such patterns is to make use of
+PCRE2's
+.\" HTML 
+.\" 
+"subroutine"
+.\"
+facility. Re-writing the above pattern as
+.sp
+  ((ab)(?2){0,999}c)(?1){0,2}
+.sp
+reduces the memory requirements to around 16KiB, and indeed it remains under
+20KiB even with the outer repetition increased to 100. However, this kind of
+pattern is not always exactly equivalent, because any captures within
+subroutine calls are lost when the subroutine completes. If this is not a
+problem, this kind of rewriting will allow you to process patterns that PCRE2
+cannot otherwise handle. The matching performance of the two different versions
+of the pattern are roughly the same. (This applies from release 10.30 - things
+were different in earlier releases.)
+.
+.
+.SH "STACK AND HEAP USAGE AT RUN TIME"
+.rs
+.sp
+From release 10.30, the interpretive (non-JIT) version of \fBpcre2_match()\fP
+uses very little system stack at run time. In earlier releases recursive
+function calls could use a great deal of stack, and this could cause problems,
+but this usage has been eliminated. Backtracking positions are now explicitly
+remembered in memory frames controlled by the code.
+.P
+The size of each frame depends on the size of pointer variables and the number
+of capturing parenthesized groups in the pattern being matched. On a 64-bit
+system the frame size for a pattern with no captures is 128 bytes. For each
+capturing group the size increases by 16 bytes.
+.P
+Until release 10.41, an initial 20KiB frames vector was allocated on the system
+stack, but this still caused some issues for multi-thread applications where
+each thread has a very small stack. From release 10.41 backtracking memory
+frames are always held in heap memory. An initial heap allocation is obtained
+the first time any match data block is passed to \fBpcre2_match()\fP. This is
+remembered with the match data block and re-used if that block is used for
+another match. It is freed when the match data block itself is freed.
+.P
+The size of the initial block is the larger of 20KiB or ten times the pattern's
+frame size, unless the heap limit is less than this, in which case the heap
+limit is used. If the initial block proves to be too small during matching, it
+is replaced by a larger block, subject to the heap limit. The heap limit is
+checked only when a new block is to be allocated. Reducing the heap limit
+between calls to \fBpcre2_match()\fP with the same match data block does not
+affect the saved block.
+.P
+In contrast to \fBpcre2_match()\fP, \fBpcre2_dfa_match()\fP does use recursive
+function calls, but only for processing atomic groups, lookaround assertions,
+and recursion within the pattern. The original version of the code used to
+allocate quite large internal workspace vectors on the stack, which caused some
+problems for some patterns in environments with small stacks. From release
+10.32 the code for \fBpcre2_dfa_match()\fP has been re-factored to use heap
+memory when necessary for internal workspace when recursing, though recursive
+function calls are still used.
+.P
+The "match depth" parameter can be used to limit the depth of function
+recursion, and the "match heap" parameter to limit heap memory in
+\fBpcre2_dfa_match()\fP.
+.
+.
+.SH "PROCESSING TIME"
+.rs
+.sp
+Certain items in regular expression patterns are processed more efficiently
+than others. It is more efficient to use a character class like [aeiou] than a
+set of single-character alternatives such as (a|e|i|o|u). In general, the
+simplest construction that provides the required behaviour is usually the most
+efficient. Jeffrey Friedl's book contains a lot of useful general discussion
+about optimizing regular expressions for efficient performance. This document
+contains a few observations about PCRE2.
+.P
+Using Unicode character properties (the \ep, \eP, and \eX escapes) is slow,
+because PCRE2 has to use a multi-stage table lookup whenever it needs a
+character's property. If you can find an alternative pattern that does not use
+character properties, it will probably be faster.
+.P
+By default, the escape sequences \eb, \ed, \es, and \ew, and the POSIX
+character classes such as [:alpha:] do not use Unicode properties, partly for
+backwards compatibility, and partly for performance reasons. However, you can
+set the PCRE2_UCP option or start the pattern with (*UCP) if you want Unicode
+character properties to be used. This can double the matching time for items
+such as \ed, when matched with \fBpcre2_match()\fP; the performance loss is
+less with a DFA matching function, and in both cases there is not much
+difference for \eb.
+.P
+When a pattern begins with .* not in atomic parentheses, nor in parentheses
+that are the subject of a backreference, and the PCRE2_DOTALL option is set,
+the pattern is implicitly anchored by PCRE2, since it can match only at the
+start of a subject string. If the pattern has multiple top-level branches, they
+must all be anchorable. The optimization can be disabled by the
+PCRE2_NO_DOTSTAR_ANCHOR option, and is automatically disabled if the pattern
+contains (*PRUNE) or (*SKIP).
+.P
+If PCRE2_DOTALL is not set, PCRE2 cannot make this optimization, because the
+dot metacharacter does not then match a newline, and if the subject string
+contains newlines, the pattern may match from the character immediately
+following one of them instead of from the very start. For example, the pattern
+.sp
+  .*second
+.sp
+matches the subject "first\enand second" (where \en stands for a newline
+character), with the match starting at the seventh character. In order to do
+this, PCRE2 has to retry the match starting after every newline in the subject.
+.P
+If you are using such a pattern with subject strings that do not contain
+newlines, the best performance is obtained by setting PCRE2_DOTALL, or starting
+the pattern with ^.* or ^.*? to indicate explicit anchoring. That saves PCRE2
+from having to scan along the subject looking for a newline to restart at.
+.P
+Beware of patterns that contain nested indefinite repeats. These can take a
+long time to run when applied to a string that does not match. Consider the
+pattern fragment
+.sp
+  ^(a+)*
+.sp
+This can match "aaaa" in 16 different ways, and this number increases very
+rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4
+times, and for each of those cases other than 0 or 4, the + repeats can match
+different numbers of times.) When the remainder of the pattern is such that the
+entire match is going to fail, PCRE2 has in principle to try every possible
+variation, and this can take an extremely long time, even for relatively short
+strings.
+.P
+An optimization catches some of the more simple cases such as
+.sp
+  (a+)*b
+.sp
+where a literal character follows. Before embarking on the standard matching
+procedure, PCRE2 checks that there is a "b" later in the subject string, and if
+there is not, it fails the match immediately. However, when there is no
+following literal this optimization cannot be used. You can see the difference
+by comparing the behaviour of
+.sp
+  (a+)*\ed
+.sp
+with the pattern above. The former gives a failure almost instantly when
+applied to a whole line of "a" characters, whereas the latter takes an
+appreciable time with strings longer than about 20 characters.
+.P
+In many cases, the solution to this kind of performance issue is to use an
+atomic group or a possessive quantifier. This can often reduce memory
+requirements as well. As another example, consider this pattern:
+.sp
+  ([^<]|<(?!inet))+
+.sp
+It matches from wherever it starts until it encounters "
+.\" 
+"The match context"
+.\"
+in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation.
+.P
+The \fBpcre2test\fP test program has a modifier called "find_limits" which, if
+applied to a subject line, causes it to find the smallest limits that allow a
+pattern to match. This is done by repeatedly matching with different limits.

+.SH DESCRIPTION
+.rs
+.sp
+This set of functions provides a POSIX-style API for the PCRE2 regular
+expression 8-bit library. There are no POSIX-style wrappers for PCRE2's 16-bit
+and 32-bit libraries. See the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation for a description of PCRE2's native API, which contains much
+additional functionality.
+.P
+\fBIMPORTANT NOTE\fP: The functions described here are NOT thread-safe, and
+should not be used in multi-threaded applications. They are also limited to
+processing subjects that are not bigger than 2GB. Use the native API instead.
+.P
+These functions are wrapper functions that ultimately call the PCRE2 native
+API. Their prototypes are defined in the \fBpcre2posix.h\fP header file, and
+they all have unique names starting with \fBpcre2_\fP. However, the
+\fBpcre2posix.h\fP header also contains macro definitions that convert the
+standard POSIX names such \fBregcomp()\fP into \fBpcre2_regcomp()\fP etc. This
+means that a program can use the usual POSIX names without running the risk of
+accidentally linking with POSIX functions from a different library.
+.P
+On Unix-like systems the PCRE2 POSIX library is called \fBlibpcre2-posix\fP, so
+can be accessed by adding \fB-lpcre2-posix\fP to the command for linking an
+application. Because the POSIX functions call the native ones, it is also
+necessary to add \fB-lpcre2-8\fP.
+.P
+On Windows systems, if you are linking to a DLL version of the library, it is
+recommended that \fBPCRE2POSIX_SHARED\fP is defined before including the
+\fBpcre2posix.h\fP header, as it will allow for a more efficient way to
+invoke the functions by adding the \fB__declspec(dllimport)\fP decorator.
+.P
+Although they were not defined as prototypes in \fBpcre2posix.h\fP, releases
+10.33 to 10.36 of the library contained functions with the POSIX names
+\fBregcomp()\fP etc. These simply passed their arguments to the PCRE2
+functions. These functions were provided for backwards compatibility with
+earlier versions of PCRE2, which had only POSIX names. However, this has proved
+troublesome in situations where a program links with several libraries, some of
+which use PCRE2's POSIX interface while others use the real POSIX functions.
+For this reason, the POSIX names have been removed since release 10.37.
+.P
+Calling the header file \fBpcre2posix.h\fP avoids any conflict with other POSIX
+libraries. It can, of course, be renamed or aliased as \fBregex.h\fP, which is
+the "correct" name, if there is no clash. It provides two structure types,
+\fIregex_t\fP for compiled internal forms, and \fIregmatch_t\fP for returning
+captured substrings. It also defines some constants whose names start with
+"REG_"; these are used for setting options and identifying error codes.
+.
+.
+.SH "USING THE POSIX FUNCTIONS"
+.rs
+.sp
+Note that these functions are just POSIX-style wrappers for PCRE2's native API.
+They do not give POSIX regular expression behaviour, and they are not
+thread-safe or even POSIX compatible.
+.P
+Those POSIX option bits that can reasonably be mapped to PCRE2 native options
+have been implemented. In addition, the option REG_EXTENDED is defined with the
+value zero. This has no effect, but since programs that are written to the
+POSIX interface often use it, this makes it easier to slot in PCRE2 as a
+replacement library. Other POSIX options are not even defined.
+.P
+There are also some options that are not defined by POSIX. These have been
+added at the request of users who want to make use of certain PCRE2-specific
+features via the POSIX calling interface or to add BSD or GNU functionality.
+.P
+When PCRE2 is called via these functions, it is only the API that is POSIX-like
+in style. The syntax and semantics of the regular expressions themselves are
+still those of Perl, subject to the setting of various PCRE2 options, as
+described below. "POSIX-like in style" means that the API approximates to the
+POSIX definition; it is not fully POSIX-compatible, and in multi-unit encoding
+domains it is probably even less compatible.
+.P
+The descriptions below use the actual names of the functions, but, as described
+above, the standard POSIX names (without the \fBpcre2_\fP prefix) may also be
+used.
+.
+.
+.SH "COMPILING A PATTERN"
+.rs
+.sp
+The function \fBpcre2_regcomp()\fP is called to compile a pattern into an
+internal form. By default, the pattern is a C string terminated by a binary
+zero (but see REG_PEND below). The \fIpreg\fP argument is a pointer to a
+\fBregex_t\fP structure that is used as a base for storing information about
+the compiled regular expression. It is also used for input when REG_PEND is
+set. The \fBregex_t\fP structure used by \fBpcre2_regcomp()\fP is defined in
+\fBpcre2posix.h\fP and is not the same as the structure used by other libraries
+that provide POSIX-style matching.
+.P
+The argument \fIcflags\fP is either zero, or contains one or more of the bits
+defined by the following macros:
+.sp
+  REG_DOTALL
+.sp
+The PCRE2_DOTALL option is set when the regular expression is passed for
+compilation to the native function. Note that REG_DOTALL is not part of the
+POSIX standard.
+.sp
+  REG_ICASE
+.sp
+The PCRE2_CASELESS option is set when the regular expression is passed for
+compilation to the native function.
+.sp
+  REG_NEWLINE
+.sp
+The PCRE2_MULTILINE option is set when the regular expression is passed for
+compilation to the native function. Note that this does \fInot\fP mimic the
+defined POSIX behaviour for REG_NEWLINE (see the following section).
+.sp
+  REG_NOSPEC
+.sp
+The PCRE2_LITERAL option is set when the regular expression is passed for
+compilation to the native function. This disables all meta characters in the
+pattern, causing it to be treated as a literal string. The only other options
+that are allowed with REG_NOSPEC are REG_ICASE, REG_NOSUB, REG_PEND, and
+REG_UTF. Note that REG_NOSPEC is not part of the POSIX standard.
+.sp
+  REG_NOSUB
+.sp
+When a pattern that is compiled with this flag is passed to
+\fBpcre2_regexec()\fP for matching, the \fInmatch\fP and \fIpmatch\fP arguments
+are ignored, and no captured strings are returned. Versions of the PCRE library
+prior to 10.22 used to set the PCRE2_NO_AUTO_CAPTURE compile option, but this
+no longer happens because it disables the use of backreferences.
+.sp
+  REG_PEND
+.sp
+If this option is set, the \fBreg_endp\fP field in the \fIpreg\fP structure
+(which has the type const char *) must be set to point to the character beyond
+the end of the pattern before calling \fBpcre2_regcomp()\fP. The pattern itself
+may now contain binary zeros, which are treated as data characters. Without
+REG_PEND, a binary zero terminates the pattern and the \fBre_endp\fP field is
+ignored. This is a GNU extension to the POSIX standard and should be used with
+caution in software intended to be portable to other systems.
+.sp
+  REG_UCP
+.sp
+The PCRE2_UCP option is set when the regular expression is passed for
+compilation to the native function. This causes PCRE2 to use Unicode properties
+when matching \ed, \ew, etc., instead of just recognizing ASCII values. Note
+that REG_UCP is not part of the POSIX standard.
+.sp
+  REG_UNGREEDY
+.sp
+The PCRE2_UNGREEDY option is set when the regular expression is passed for
+compilation to the native function. Note that REG_UNGREEDY is not part of the
+POSIX standard.
+.sp
+  REG_UTF
+.sp
+The PCRE2_UTF option is set when the regular expression is passed for
+compilation to the native function. This causes the pattern itself and all data
+strings used for matching it to be treated as UTF-8 strings. Note that REG_UTF
+is not part of the POSIX standard.
+.P
+In the absence of these flags, no options are passed to the native function.
+This means that the regex is compiled with PCRE2 default semantics. In
+particular, the way it handles newline characters in the subject string is the
+Perl way, not the POSIX way. Note that setting PCRE2_MULTILINE has only
+\fIsome\fP of the effects specified for REG_NEWLINE. It does not affect the way
+newlines are matched by the dot metacharacter (they are not) or by a negative
+class such as [^a] (they are).
+.P
+The yield of \fBpcre2_regcomp()\fP is zero on success, and non-zero otherwise.
+The \fIpreg\fP structure is filled in on success, and one other member of the
+structure (as well as \fIre_endp\fP) is public: \fIre_nsub\fP contains the
+number of capturing subpatterns in the regular expression. Various error codes
+are defined in the header file.
+.P
+NOTE: If the yield of \fBpcre2_regcomp()\fP is non-zero, you must not attempt
+to use the contents of the \fIpreg\fP structure. If, for example, you pass it
+to \fBpcre2_regexec()\fP, the result is undefined and your program is likely to
+crash.
+.
+.
+.SH "MATCHING NEWLINE CHARACTERS"
+.rs
+.sp
+This area is not simple, because POSIX and Perl take different views of things.
+It is not possible to get PCRE2 to obey POSIX semantics, but then PCRE2 was
+never intended to be a POSIX engine. The following table lists the different
+possibilities for matching newline characters in Perl and PCRE2:
+.sp
+                          Default   Change with
+.sp
+  . matches newline          no     PCRE2_DOTALL
+  newline matches [^a]       yes    not changeable
+  $ matches \en at end        yes    PCRE2_DOLLAR_ENDONLY
+  $ matches \en in middle     no     PCRE2_MULTILINE
+  ^ matches \en in middle     no     PCRE2_MULTILINE
+.sp
+This is the equivalent table for a POSIX-compatible pattern matcher:
+.sp
+                          Default   Change with
+.sp
+  . matches newline          yes    REG_NEWLINE
+  newline matches [^a]       yes    REG_NEWLINE
+  $ matches \en at end        no     REG_NEWLINE
+  $ matches \en in middle     no     REG_NEWLINE
+  ^ matches \en in middle     no     REG_NEWLINE
+.sp
+This behaviour is not what happens when PCRE2 is called via its POSIX
+API. By default, PCRE2's behaviour is the same as Perl's, except that there is
+no equivalent for PCRE2_DOLLAR_ENDONLY in Perl. In both PCRE2 and Perl, there
+is no way to stop newline from matching [^a].
+.P
+Default POSIX newline handling can be obtained by setting PCRE2_DOTALL and
+PCRE2_DOLLAR_ENDONLY when calling \fBpcre2_compile()\fP directly, but there is
+no way to make PCRE2 behave exactly as for the REG_NEWLINE action. When using
+the POSIX API, passing REG_NEWLINE to PCRE2's \fBpcre2_regcomp()\fP function
+causes PCRE2_MULTILINE to be passed to \fBpcre2_compile()\fP, and REG_DOTALL
+passes PCRE2_DOTALL. There is no way to pass PCRE2_DOLLAR_ENDONLY.
+.
+.
+.SH "MATCHING A PATTERN"
+.rs
+.sp
+The function \fBpcre2_regexec()\fP is called to match a compiled pattern
+\fIpreg\fP against a given \fIstring\fP, which is by default terminated by a
+zero byte (but see REG_STARTEND below), subject to the options in \fIeflags\fP.
+These can be:
+.sp
+  REG_NOTBOL
+.sp
+The PCRE2_NOTBOL option is set when calling the underlying PCRE2 matching
+function.
+.sp
+  REG_NOTEMPTY
+.sp
+The PCRE2_NOTEMPTY option is set when calling the underlying PCRE2 matching
+function. Note that REG_NOTEMPTY is not part of the POSIX standard. However,
+setting this option can give more POSIX-like behaviour in some situations.
+.sp
+  REG_NOTEOL
+.sp
+The PCRE2_NOTEOL option is set when calling the underlying PCRE2 matching
+function.
+.sp
+  REG_STARTEND
+.sp
+When this option is set, the subject string starts at \fIstring\fP +
+\fIpmatch[0].rm_so\fP and ends at \fIstring\fP + \fIpmatch[0].rm_eo\fP, which
+should point to the first character beyond the string. There may be binary
+zeros within the subject string, and indeed, using REG_STARTEND is the only
+way to pass a subject string that contains a binary zero.
+.P
+Whatever the value of \fIpmatch[0].rm_so\fP, the offsets of the matched string
+and any captured substrings are still given relative to the start of
+\fIstring\fP itself. (Before PCRE2 release 10.30 these were given relative to
+\fIstring\fP + \fIpmatch[0].rm_so\fP, but this differs from other
+implementations.)
+.P
+This is a BSD extension, compatible with but not specified by IEEE Standard
+1003.2 (POSIX.2), and should be used with caution in software intended to be
+portable to other systems. Note that a non-zero \fIrm_so\fP does not imply
+REG_NOTBOL; REG_STARTEND affects only the location and length of the string,
+not how it is matched. Setting REG_STARTEND and passing \fIpmatch\fP as NULL
+are mutually exclusive; the error REG_INVARG is returned.
+.P
+If the pattern was compiled with the REG_NOSUB flag, no data about any matched
+strings is returned. The \fInmatch\fP and \fIpmatch\fP arguments of
+\fBpcre2_regexec()\fP are ignored (except possibly as input for REG_STARTEND).
+.P
+The value of \fInmatch\fP may be zero, and the value \fIpmatch\fP may be NULL
+(unless REG_STARTEND is set); in both these cases no data about any matched
+strings is returned.
+.P
+Otherwise, the portion of the string that was matched, and also any captured
+substrings, are returned via the \fIpmatch\fP argument, which points to an
+array of \fInmatch\fP structures of type \fIregmatch_t\fP, containing the
+members \fIrm_so\fP and \fIrm_eo\fP. These contain the byte offset to the first
+character of each substring and the offset to the first character after the end
+of each substring, respectively. The 0th element of the vector relates to the
+entire portion of \fIstring\fP that was matched; subsequent elements relate to
+the capturing subpatterns of the regular expression. Unused entries in the
+array have both structure members set to -1.
+.P
+\fIregmatch_t\fP as well as the \fIregoff_t\fP typedef it uses are defined in
+\fBpcre2posix.h\fP and are not warranted to have the same size or layout as other
+similarly named types from other libraries that provide POSIX-style matching.
+.P
+A successful match yields a zero return; various error codes are defined in the
+header file, of which REG_NOMATCH is the "expected" failure code.
+.
+.
+.SH "ERROR MESSAGES"
+.rs
+.sp
+The \fBpcre2_regerror()\fP function maps a non-zero errorcode from either
+\fBpcre2_regcomp()\fP or \fBpcre2_regexec()\fP to a printable message. If
+\fIpreg\fP is not NULL, the error should have arisen from the use of that
+structure. A message terminated by a binary zero is placed in \fIerrbuf\fP. If
+the buffer is too short, only the first \fIerrbuf_size\fP - 1 characters of the
+error message are used. The yield of the function is the size of buffer needed
+to hold the whole message, including the terminating zero. This value is
+greater than \fIerrbuf_size\fP if the message was truncated.
+.
+.
+.SH MEMORY USAGE
+.rs
+.sp
+Compiling a regular expression causes memory to be allocated and associated
+with the \fIpreg\fP structure. The function \fBpcre2_regfree()\fP frees all
+such memory, after which \fIpreg\fP may no longer be used as a compiled
+expression.

+.TH PCRE2SAMPLE 3 "02 February 2016" "PCRE2 10.22"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 SAMPLE PROGRAM"
+.rs
+.sp
+A simple, complete demonstration program to get you started with using PCRE2 is
+supplied in the file \fIpcre2demo.c\fP in the \fBsrc\fP directory in the PCRE2
+distribution. A listing of this program is given in the
+.\" HREF
+\fBpcre2demo\fP
+.\"
+documentation. If you do not have a copy of the PCRE2 distribution, you can
+save this listing to re-create the contents of \fIpcre2demo.c\fP.
+.P
+The demonstration program compiles the regular expression that is its
+first argument, and matches it against the subject string in its second
+argument. No PCRE2 options are set, and default character tables are used. If
+matching succeeds, the program outputs the portion of the subject that matched,
+together with the contents of any captured substrings.
+.P
+If the -g option is given on the command line, the program then goes on to
+check for further matches of the same regular expression in the same subject
+string. The logic is a little bit tricky because of the possibility of matching
+an empty string. Comments in the code explain what is going on.
+.P
+The code in \fBpcre2demo.c\fP is an 8-bit program that uses the PCRE2 8-bit
+library. It handles strings and characters that are stored in 8-bit code units.
+By default, one character corresponds to one code unit, but if the pattern
+starts with "(*UTF)", both it and the subject are treated as UTF-8 strings,
+where characters may occupy multiple code units.
+.P
+If PCRE2 is installed in the standard include and library directories for your
+operating system, you should be able to compile the demonstration program using
+a command like this:
+.sp
+  cc -o pcre2demo pcre2demo.c -lpcre2-8
+.sp
+If PCRE2 is installed elsewhere, you may need to add additional options to the
+command line. For example, on a Unix-like system that has PCRE2 installed in
+\fI/usr/local\fP, you can compile the demonstration program using a command
+like this:
+.sp
+.\" JOINSH
+  cc -o pcre2demo -I/usr/local/include pcre2demo.c \e
+     -L/usr/local/lib -lpcre2-8
+.sp
+Once you have built the demonstration program, you can run simple tests like
+this:
+.sp
+  ./pcre2demo 'cat|dog' 'the cat sat on the mat'
+  ./pcre2demo -g 'cat|dog' 'the dog sat on the cat'
+.sp
+Note that there is a much more comprehensive test program, called
+.\" HREF
+\fBpcre2test\fP,
+.\"
+which supports many more facilities for testing regular expressions using all
+three PCRE2 libraries (8-bit, 16-bit, and 32-bit, though not all three need be
+installed). The
+.\" HREF
+\fBpcre2demo\fP
+.\"
+program is provided as a relatively simple coding example.
+.P
+If you try to run
+.\" HREF
+\fBpcre2demo\fP
+.\"
+when PCRE2 is not installed in the standard library directory, you may get an
+error like this on some operating systems (e.g. Solaris):
+.sp
+  ld.so.1: pcre2demo: fatal: libpcre2-8.so.0: open failed: No such file or directory
+.sp
+This is caused by the way shared library support works on those systems. You
+need to add
+.sp
+  -R/usr/local/lib
+.sp
+(for example) to the compile command to get round this problem.

+If you are running an application that uses a large number of regular
+expression patterns, it may be useful to store them in a precompiled form
+instead of having to compile them every time the application is run. However,
+if you are using the just-in-time optimization feature, it is not possible to
+save and reload the JIT data, because it is position-dependent. The host on
+which the patterns are reloaded must be running the same version of PCRE2, with
+the same code unit width, and must also have the same endianness, pointer width
+and PCRE2_SIZE type. For example, patterns compiled on a 32-bit system using
+PCRE2's 16-bit library cannot be reloaded on a 64-bit system, nor can they be
+reloaded using the 8-bit library.
+.P
+Note that "serialization" in PCRE2 does not convert compiled patterns to an
+abstract format like Java or .NET serialization. The serialized output is
+really just a bytecode dump, which is why it can only be reloaded in the same
+environment as the one that created it. Hence the restrictions mentioned above.
+Applications that are not statically linked with a fixed version of PCRE2 must
+be prepared to recompile patterns from their sources, in order to be immune to
+PCRE2 upgrades.
+.
+.
+.SH "SECURITY CONCERNS"
+.rs
+.sp
+The facility for saving and restoring compiled patterns is intended for use
+within individual applications. As such, the data supplied to
+\fBpcre2_serialize_decode()\fP is expected to be trusted data, not data from
+arbitrary external sources. There is only some simple consistency checking, not
+complete validation of what is being re-loaded. Corrupted data may cause
+undefined results. For example, if the length field of a pattern in the
+serialized data is corrupted, the deserializing code may read beyond the end of
+the byte stream that is passed to it.
+.
+.
+.SH "SAVING COMPILED PATTERNS"
+.rs
+.sp
+Before compiled patterns can be saved they must be serialized, which in PCRE2
+means converting the pattern to a stream of bytes. A single byte stream may
+contain any number of compiled patterns, but they must all use the same
+character tables. A single copy of the tables is included in the byte stream
+(its size is 1088 bytes). For more details of character tables, see the
+.\" HTML 
+.\" 
+section on locale support
+.\"
+in the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation.
+.P
+The function \fBpcre2_serialize_encode()\fP creates a serialized byte stream
+from a list of compiled patterns. Its first two arguments specify the list,
+being a pointer to a vector of pointers to compiled patterns, and the length of
+the vector. The third and fourth arguments point to variables which are set to
+point to the created byte stream and its length, respectively. The final
+argument is a pointer to a general context, which can be used to specify custom
+memory management functions. If this argument is NULL, \fBmalloc()\fP is used
+to obtain memory for the byte stream. The yield of the function is the number
+of serialized patterns, or one of the following negative error codes:
+.sp
+  PCRE2_ERROR_BADDATA      the number of patterns is zero or less
+  PCRE2_ERROR_BADMAGIC     mismatch of id bytes in one of the patterns
+  PCRE2_ERROR_NOMEMORY     memory allocation failed
+  PCRE2_ERROR_MIXEDTABLES  the patterns do not all use the same tables
+  PCRE2_ERROR_NULL         the 1st, 3rd, or 4th argument is NULL
+.sp
+PCRE2_ERROR_BADMAGIC means either that a pattern's code has been corrupted, or
+that a slot in the vector does not point to a compiled pattern.
+.P
+Once a set of patterns has been serialized you can save the data in any
+appropriate manner. Here is sample code that compiles two patterns and writes
+them to a file. It assumes that the variable \fIfd\fP refers to a file that is
+open for output. The error checking that should be present in a real
+application has been omitted for simplicity.
+.sp
+  int errorcode;
+  uint8_t *bytes;
+  PCRE2_SIZE erroroffset;
+  PCRE2_SIZE bytescount;
+  pcre2_code *list_of_codes[2];
+  list_of_codes[0] = pcre2_compile("first pattern",
+    PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+  list_of_codes[1] = pcre2_compile("second pattern",
+    PCRE2_ZERO_TERMINATED, 0, &errorcode, &erroroffset, NULL);
+  errorcode = pcre2_serialize_encode(list_of_codes, 2, &bytes,
+    &bytescount, NULL);
+  errorcode = fwrite(bytes, 1, bytescount, fd);
+.sp
+Note that the serialized data is binary data that may contain any of the 256
+possible byte values. On systems that make a distinction between binary and
+non-binary data, be sure that the file is opened for binary output.
+.P
+Serializing a set of patterns leaves the original data untouched, so they can
+still be used for matching. Their memory must eventually be freed in the usual
+way by calling \fBpcre2_code_free()\fP. When you have finished with the byte
+stream, it too must be freed by calling \fBpcre2_serialize_free()\fP. If this
+function is called with a NULL argument, it returns immediately without doing
+anything.
+.
+.
+.SH "RE-USING PRECOMPILED PATTERNS"
+.rs
+.sp
+In order to re-use a set of saved patterns you must first make the serialized
+byte stream available in main memory (for example, by reading from a file). The
+management of this memory block is up to the application. You can use the
+\fBpcre2_serialize_get_number_of_codes()\fP function to find out how many
+compiled patterns are in the serialized data without actually decoding the
+patterns:
+.sp
+  uint8_t *bytes = ;
+  int32_t number_of_codes = pcre2_serialize_get_number_of_codes(bytes);
+.sp
+The \fBpcre2_serialize_decode()\fP function reads a byte stream and recreates
+the compiled patterns in new memory blocks, setting pointers to them in a
+vector. The first two arguments are a pointer to a suitable vector and its
+length, and the third argument points to a byte stream. The final argument is a
+pointer to a general context, which can be used to specify custom memory
+management functions for the decoded patterns. If this argument is NULL,
+\fBmalloc()\fP and \fBfree()\fP are used. After deserialization, the byte
+stream is no longer needed and can be discarded.
+.sp
+  pcre2_code *list_of_codes[2];
+  uint8_t *bytes = ;
+  int32_t number_of_codes =
+    pcre2_serialize_decode(list_of_codes, 2, bytes, NULL);
+.sp
+If the vector is not large enough for all the patterns in the byte stream, it
+is filled with those that fit, and the remainder are ignored. The yield of the
+function is the number of decoded patterns, or one of the following negative
+error codes:
+.sp
+  PCRE2_ERROR_BADDATA    second argument is zero or less
+  PCRE2_ERROR_BADMAGIC   mismatch of id bytes in the data
+  PCRE2_ERROR_BADMODE    mismatch of code unit size or PCRE2 version
+  PCRE2_ERROR_BADSERIALIZEDDATA  other sanity check failure
+  PCRE2_ERROR_MEMORY     memory allocation failed
+  PCRE2_ERROR_NULL       first or third argument is NULL
+.sp
+PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled
+on a system with different endianness.
+.P
+Decoded patterns can be used for matching in the usual way, and must be freed
+by calling \fBpcre2_code_free()\fP. However, be aware that there is a potential
+race issue if you are using multiple patterns that were decoded from a single
+byte stream in a multithreaded application. A single copy of the character
+tables is used by all the decoded patterns and a reference count is used to
+arrange for its memory to be automatically freed when the last pattern is
+freed, but there is no locking on this reference count. Therefore, if you want
+to call \fBpcre2_code_free()\fP for these patterns in different threads, you
+must arrange your own locking, and ensure that \fBpcre2_code_free()\fP cannot
+be called by two threads at the same time.
+.P
+If a pattern was processed by \fBpcre2_jit_compile()\fP before being
+serialized, the JIT data is discarded and so is no longer available after a
+save/restore cycle. You can, however, process a restored pattern with
+\fBpcre2_jit_compile()\fP if you wish.

+.TH PCRE2SYNTAX 3 "12 October 2023" "PCRE2 10.43"
+.SH NAME
+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH "PCRE2 REGULAR EXPRESSION SYNTAX SUMMARY"
+.rs
+.sp
+The full syntax and semantics of the regular expressions that are supported by
+PCRE2 are described in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation. This document contains a quick-reference summary of the syntax.
+.
+.
+.SH "QUOTING"
+.rs
+.sp
+  \ex         where x is non-alphanumeric is a literal x
+  \eQ...\eE    treat enclosed characters as literal
+.sp
+Note that white space inside \eQ...\eE is always treated as literal, even if
+PCRE2_EXTENDED is set, causing most other white space to be ignored.
+.
+.
+.SH "BRACED ITEMS"
+.rs
+.sp
+With one exception, wherever brace characters { and } are required to enclose
+data for constructions such as \eg{2} or \ek{name}, space and/or horizontal tab
+characters that follow { or precede } are allowed and are ignored. In the case
+of quantifiers, they may also appear before or after the comma. The exception
+is \eu{...} which is not Perl-compatible and is recognized only when
+PCRE2_EXTRA_ALT_BSUX is set. This is an ECMAScript compatibility feature, and
+follows ECMAScript's behaviour.
+.
+.
+.SH "ESCAPED CHARACTERS"
+.rs
+.sp
+This table applies to ASCII and Unicode environments. An unrecognized escape
+sequence causes an error.
+.sp
+  \ea         alarm, that is, the BEL character (hex 07)
+  \ecx        "control-x", where x is a non-control ASCII character
+  \ee         escape (hex 1B)
+  \ef         form feed (hex 0C)
+  \en         newline (hex 0A)
+  \er         carriage return (hex 0D)
+  \et         tab (hex 09)
+  \e0dd       character with octal code 0dd
+  \eddd       character with octal code ddd, or backreference
+  \eo{ddd..}  character with octal code ddd..
+  \eN{U+hh..} character with Unicode code point hh.. (Unicode mode only)
+  \exhh       character with hex code hh
+  \ex{hh..}   character with hex code hh..
+.sp
+If PCRE2_ALT_BSUX or PCRE2_EXTRA_ALT_BSUX is set ("ALT_BSUX mode"), the
+following are also recognized:
+.sp
+  \eU         the character "U"
+  \euhhhh     character with hex code hhhh
+  \eu{hh..}   character with hex code hh.. but only for EXTRA_ALT_BSUX
+.sp
+When \ex is not followed by {, from zero to two hexadecimal digits are read,
+but in ALT_BSUX mode \ex must be followed by two hexadecimal digits to be
+recognized as a hexadecimal escape; otherwise it matches a literal "x".
+Likewise, if \eu (in ALT_BSUX mode) is not followed by four hexadecimal digits
+or (in EXTRA_ALT_BSUX mode) a sequence of hex digits in curly brackets, it
+matches a literal "u".
+.P
+Note that \e0dd is always an octal code. The treatment of backslash followed by
+a non-zero digit is complicated; for details see the section
+.\" HTML 
+.\" 
+"Non-printing characters"
+.\"
+in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation, where details of escape processing in EBCDIC environments are
+also given. \eN{U+hh..} is synonymous with \ex{hh..} in PCRE2 but is not
+supported in EBCDIC environments. Note that \eN not followed by an opening
+curly bracket has a different meaning (see below).
+.
+.
+.SH "CHARACTER TYPES"
+.rs
+.sp
+  .          any character except newline;
+               in dotall mode, any character whatsoever
+  \eC         one code unit, even in UTF mode (best avoided)
+  \ed         a decimal digit
+  \eD         a character that is not a decimal digit
+  \eh         a horizontal white space character
+  \eH         a character that is not a horizontal white space character
+  \eN         a character that is not a newline
+  \ep{\fIxx\fP}     a character with the \fIxx\fP property
+  \eP{\fIxx\fP}     a character without the \fIxx\fP property
+  \eR         a newline sequence
+  \es         a white space character
+  \eS         a character that is not a white space character
+  \ev         a vertical white space character
+  \eV         a character that is not a vertical white space character
+  \ew         a "word" character
+  \eW         a "non-word" character
+  \eX         a Unicode extended grapheme cluster
+.sp
+\eC is dangerous because it may leave the current matching point in the middle
+of a UTF-8 or UTF-16 character. The application can lock out the use of \eC by
+setting the PCRE2_NEVER_BACKSLASH_C option. It is also possible to build PCRE2
+with the use of \eC permanently disabled.
+.P
+By default, \ed, \es, and \ew match only ASCII characters, even in UTF-8 mode
+or in the 16-bit and 32-bit libraries. However, if locale-specific matching is
+happening, \es and \ew may also match characters with code points in the range
+128-255. If the PCRE2_UCP option is set, the behaviour of these escape
+sequences is changed to use Unicode properties and they match many more
+characters, but there are some option settings that can restrict individual
+sequences to matching only ASCII characters.
+.P
+Property descriptions in \ep and \eP are matched caselessly; hyphens,
+underscores, and white space are ignored, in accordance with Unicode's "loose
+matching" rules.

+.TH PCRE2TEST 1 "24 April 2024" "PCRE 10.44"
+.SH NAME
+pcre2test - a program for testing Perl-compatible regular expressions.
+.SH SYNOPSIS
+.rs
+.sp
+.B pcre2test "[options] [input file [output file]]"
+.sp
+\fBpcre2test\fP is a test program for the PCRE2 regular expression libraries,
+but it can also be used for experimenting with regular expressions. This
+document describes the features of the test program; for details of the regular
+expressions themselves, see the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation. For details of the PCRE2 library function calls and their
+options, see the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation.
+.P
+The input for \fBpcre2test\fP is a sequence of regular expression patterns and
+subject strings to be matched. There are also command lines for setting
+defaults and controlling some special actions. The output shows the result of
+each match attempt. Modifiers on external or internal command lines, the
+patterns, and the subject lines specify PCRE2 function options, control how the
+subject is processed, and what output is produced.
+.P
+There are many obscure modifiers, some of which are specifically designed for
+use in conjunction with the test script and data files that are distributed as
+part of PCRE2. All the modifiers are documented here, some without much
+justification, but many of them are unlikely to be of use except when testing
+the libraries.
+.
+.
+.SH "PCRE2's 8-BIT, 16-BIT AND 32-BIT LIBRARIES"
+.rs
+.sp
+Different versions of the PCRE2 library can be built to support character
+strings that are encoded in 8-bit, 16-bit, or 32-bit code units. One, two, or
+all three of these libraries may be simultaneously installed. The
+\fBpcre2test\fP program can be used to test all the libraries. However, its own
+input and output are always in 8-bit format. When testing the 16-bit or 32-bit
+libraries, patterns and subject strings are converted to 16-bit or 32-bit
+format before being passed to the library functions. Results are converted back
+to 8-bit code units for output.
+.P
+In the rest of this document, the names of library functions and structures
+are given in generic form, for example, \fBpcre2_compile()\fP. The actual
+names used in the libraries have a suffix _8, _16, or _32, as appropriate.
+.
+.
+.\" HTML 
+.SH "INPUT ENCODING"
+.rs
+.sp
+Input to \fBpcre2test\fP is processed line by line, either by calling the C
+library's \fBfgets()\fP function, or via the \fBlibreadline\fP or \fBlibedit\fP
+library. In some Windows environments character 26 (hex 1A) causes an immediate
+end of file, and no further data is read, so this character should be avoided
+unless you really want that action.
+.P
+The input is processed using C's string functions, so must not contain binary
+zeros, even though in Unix-like environments, \fBfgets()\fP treats any bytes
+other than newline as data characters. An error is generated if a binary zero
+is encountered. By default subject lines are processed for backslash escapes,
+which makes it possible to include any data value in strings that are passed to
+the library for matching. For patterns, there is a facility for specifying some
+or all of the 8-bit input characters as hexadecimal pairs, which makes it
+possible to include binary zeros.
+.
+.
+.SS "Input for the 16-bit and 32-bit libraries"
+.rs
+.sp
+When testing the 16-bit or 32-bit libraries, there is a need to be able to
+generate character code points greater than 255 in the strings that are passed
+to the library. For subject lines, backslash escapes can be used. In addition,
+when the \fButf\fP modifier (see
+.\" HTML 
+.\" 
+"Setting compilation options"
+.\"
+below) is set, the pattern and any following subject lines are interpreted as
+UTF-8 strings and translated to UTF-16 or UTF-32 as appropriate.
+.P
+For non-UTF testing of wide characters, the \fButf8_input\fP modifier can be
+used. This is mutually exclusive with \fButf\fP, and is allowed only in 16-bit
+or 32-bit mode. It causes the pattern and following subject lines to be treated
+as UTF-8 according to the original definition (RFC 2279), which allows for
+character values up to 0x7fffffff. Each character is placed in one 16-bit or
+32-bit code unit (in the 16-bit case, values greater than 0xffff cause an error
+to occur).
+.P
+UTF-8 (in its original definition) is not capable of encoding values greater
+than 0x7fffffff, but such values can be handled by the 32-bit library. When
+testing this library in non-UTF mode with \fButf8_input\fP set, if any
+character is preceded by the byte 0xff (which is an invalid byte in UTF-8)
+0x80000000 is added to the character's value. This is the only way of passing
+such code points in a pattern string. For subject strings, using an escape
+sequence is preferable.
+.
+.
+.SH "COMMAND LINE OPTIONS"
+.rs
+.TP 10
+\fB-8\fP
+If the 8-bit library has been built, this option causes it to be used (this is
+the default). If the 8-bit library has not been built, this option causes an
+error.
+.TP 10
+\fB-16\fP
+If the 16-bit library has been built, this option causes it to be used. If the
+8-bit library has not been built, this is the default. If the 16-bit library
+has not been built, this option causes an error.
+.TP 10
+\fB-32\fP
+If the 32-bit library has been built, this option causes it to be used. If no
+other library has been built, this is the default. If the 32-bit library has
+not been built, this option causes an error.
+.TP 10
+\fB-ac\fP
+Behave as if each pattern has the \fBauto_callout\fP modifier, that is, insert
+automatic callouts into every pattern that is compiled.
+.TP 10
+\fB-AC\fP
+As for \fB-ac\fP, but in addition behave as if each subject line has the
+\fBcallout_extra\fP modifier, that is, show additional information from
+callouts.
+.TP 10
+\fB-b\fP
+Behave as if each pattern has the \fBfullbincode\fP modifier; the full
+internal binary form of the pattern is output after compilation.
+.TP 10
+\fB-C\fP

+about the optional features that are included, and then exit with zero exit
+code. All other options are ignored. If both -C and -LM are present, whichever
+is first is recognized.
+.TP 10
+\fB-C\fP \fIoption\fP
+Output information about a specific build-time option, then exit. This
+functionality is intended for use in scripts such as \fBRunTest\fP. The
+following options output the value and set the exit code as indicated:
+.sp
+  ebcdic-nl  the code for LF (= NL) in an EBCDIC environment:
+               0x15 or 0x25
+               0 if used in an ASCII environment
+               exit code is always 0
+  linksize   the configured internal link size (2, 3, or 4)
+               exit code is set to the link size
+  newline    the default newline setting:
+               CR, LF, CRLF, ANYCRLF, ANY, or NUL

+  pcre2-32     the 32-bit library was built
+  pcre2-8      the 8-bit library was built
+  unicode      Unicode support is available
+.sp
+If an unknown option is given, an error message is output; the exit code is 0.
+.TP 10
+\fB-d\fP
+Behave as if each pattern has the \fBdebug\fP modifier; the internal
+form and information about the compiled pattern is output after compilation;
+\fB-d\fP is equivalent to \fB-b -i\fP.
+.TP 10
+\fB-dfa\fP
+Behave as if each subject line has the \fBdfa\fP modifier; matching is done
+using the \fBpcre2_dfa_match()\fP function instead of the default
+\fBpcre2_match()\fP.
+.TP 10
+\fB-error\fP \fInumber[,number,...]\fP
+Call \fBpcre2_get_error_message()\fP for each of the error numbers in the
+comma-separated list, display the resulting messages on the standard output,
+then exit with zero exit code. The numbers may be positive or negative. This is
+a convenience facility for PCRE2 maintainers.
+.TP 10
+\fB-help\fP
+Output a brief summary these options and then exit.
+.TP 10
+\fB-i\fP
+Behave as if each pattern has the \fBinfo\fP modifier; information about the
+compiled pattern is given after compilation.
+.TP 10
+\fB-jit\fP
+Behave as if each pattern line has the \fBjit\fP modifier; after successful
+compilation, each pattern is passed to the just-in-time compiler, if available.
+.TP 10
+\fB-jitfast\fP
+Behave as if each pattern line has the \fBjitfast\fP modifier; after
+successful compilation, each pattern is passed to the just-in-time compiler, if
+available, and each subject line is passed directly to the JIT matcher via its
+"fast path".
+.TP 10
+\fB-jitverify\fP
+Behave as if each pattern line has the \fBjitverify\fP modifier; after
+successful compilation, each pattern is passed to the just-in-time compiler, if
+available, and the use of JIT for matching is verified.
+.TP 10
+\fB-LM\fP
+List modifiers: write a list of available pattern and subject modifiers to the
+standard output, then exit with zero exit code. All other options are ignored.
+If both -C and any -Lx options are present, whichever is first is recognized.
+.TP 10
+\fB-LP\fP
+List properties: write a list of recognized Unicode properties to the standard
+output, then exit with zero exit code. All other options are ignored. If both
+-C and any -Lx options are present, whichever is first is recognized.
+.TP 10
+\fB-LS\fP
+List scripts: write a list of recognized Unicode script names to the standard
+output, then exit with zero exit code. All other options are ignored. If both
+-C and any -Lx options are present, whichever is first is recognized.
+.TP 10
+\fB-pattern\fP \fImodifier-list\fP
+Behave as if each pattern line contains the given modifiers.
+.TP 10
+\fB-q\fP
+Do not output the version number of \fBpcre2test\fP at the start of execution.
+.TP 10
+\fB-S\fP \fIsize\fP
+On Unix-like systems, set the size of the run-time stack to \fIsize\fP
+mebibytes (units of 1024*1024 bytes).
+.TP 10
+\fB-subject\fP \fImodifier-list\fP
+Behave as if each subject line contains the given modifiers.
+.TP 10
+\fB-t\fP
+Run each compile and match many times with a timer, and output the resulting
+times per compile or match. When JIT is used, separate times are given for the
+initial compile and the JIT compile. You can control the number of iterations
+that are used for timing by following \fB-t\fP with a number (as a separate
+item on the command line). For example, "-t 1000" iterates 1000 times. The
+default is to iterate 500,000 times.
+.TP 10
+\fB-tm\fP
+This is like \fB-t\fP except that it times only the matching phase, not the
+compile phase.
+.TP 10
+\fB-T\fP \fB-TM\fP
+These behave like \fB-t\fP and \fB-tm\fP, but in addition, at the end of a run,
+the total times for all compiles and matches are output.
+.TP 10
+\fB-version\fP
+Output the PCRE2 version number and then exit.
+.
+.
+.SH "DESCRIPTION"
+.rs
+.sp
+If \fBpcre2test\fP is given two filename arguments, it reads from the first and
+writes to the second. If the first name is "-", input is taken from the
+standard input. If \fBpcre2test\fP is given only one argument, it reads from
+that file and writes to stdout. Otherwise, it reads from stdin and writes to
+stdout.
+.P
+When \fBpcre2test\fP is built, a configuration option can specify that it
+should be linked with the \fBlibreadline\fP or \fBlibedit\fP library. When this
+is done, if the input is from a terminal, it is read using the \fBreadline()\fP
+function. This provides line-editing and history facilities. The output from
+the \fB-help\fP option states whether or not \fBreadline()\fP will be used.
+.P
+The program handles any number of tests, each of which consists of a set of
+input lines. Each set starts with a regular expression pattern, followed by any
+number of subject lines to be matched against that pattern. In between sets of
+test data, command lines that begin with # may appear. This file format, with
+some restrictions, can also be processed by the \fBperltest.sh\fP script that
+is distributed with PCRE2 as a means of checking that the behaviour of PCRE2
+and Perl is the same. For a specification of \fBperltest.sh\fP, see the
+comments near its beginning. See also the #perltest command below.
+.P
+When the input is a terminal, \fBpcre2test\fP prompts for each line of input,
+using "re>" to prompt for regular expression patterns, and "data>" to prompt
+for subject lines. Command lines starting with # can be entered only in
+response to the "re>" prompt.
+.P
+Each subject line is matched separately and independently. If you want to do
+multi-line matches, you have to use the \en escape sequence (or \er or \er\en,
+etc., depending on the newline setting) in a single line of input to encode the
+newline sequences. There is no limit on the length of subject lines; the input
+buffer is automatically extended if it is too small. There are replication
+features that makes it possible to generate long repetitive pattern or subject
+lines without having to supply them explicitly.
+.P
+An empty line or the end of the file signals the end of the subject lines for a
+test, at which point a new pattern or command line is expected if there is
+still input to be read.
+.
+.
+.SH "COMMAND LINES"
+.rs
+.sp
+In between sets of test data, a line that begins with # is interpreted as a
+command line. If the first character is followed by white space or an
+exclamation mark, the line is treated as a comment, and ignored. Otherwise, the
+following commands are recognized:
+.sp
+  #forbid_utf
+.sp
+Subsequent patterns automatically have the PCRE2_NEVER_UTF and PCRE2_NEVER_UCP
+options set, which locks out the use of the PCRE2_UTF and PCRE2_UCP options and
+the use of (*UTF) and (*UCP) at the start of patterns. This command also forces
+an error if a subsequent pattern contains any occurrences of \eP, \ep, or \eX,
+which are still supported when PCRE2_UTF is not set, but which require Unicode
+property support to be included in the library.
+.P
+This is a trigger guard that is used in test files to ensure that UTF or
+Unicode property tests are not accidentally added to files that are used when
+Unicode support is not included in the library. Setting PCRE2_NEVER_UTF and
+PCRE2_NEVER_UCP as a default can also be obtained by the use of \fB#pattern\fP;
+the difference is that \fB#forbid_utf\fP cannot be unset, and the automatic
+options are not displayed in pattern information, to avoid cluttering up test
+output.
+.sp
+  #load 
+.sp
+This command is used to load a set of precompiled patterns from a file, as
+described in the section entitled "Saving and restoring compiled patterns"
+.\" HTML 
+.\" 
+below.
+.\"
+.sp
+  #loadtables 
+.sp
+This command is used to load a set of binary character tables that can be
+accessed by the tables=3 qualifier. Such tables can be created by the
+\fBpcre2_dftables\fP program with the -b option.
+.sp
+  #newline_default []
+.sp
+When PCRE2 is built, a default newline convention can be specified. This
+determines which characters and/or character pairs are recognized as indicating
+a newline in a pattern or subject string. The default can be overridden when a
+pattern is compiled. The standard test files contain tests of various newline
+conventions, but the majority of the tests expect a single linefeed to be
+recognized as a newline by default. Without special action the tests would fail
+when PCRE2 is compiled with either CR or CRLF as the default newline.
+.P
+The #newline_default command specifies a list of newline types that are
+acceptable as the default. The types must be one of CR, LF, CRLF, ANYCRLF,
+ANY, or NUL (in upper or lower case), for example:
+.sp
+  #newline_default LF Any anyCRLF
+.sp
+If the default newline is in the list, this command has no effect. Otherwise,
+except when testing the POSIX API, a \fBnewline\fP modifier that specifies the
+first newline convention in the list (LF in the above example) is added to any
+pattern that does not already have a \fBnewline\fP modifier. If the newline
+list is empty, the feature is turned off. This command is present in a number
+of the standard test input files.
+.P
+When the POSIX API is being tested there is no way to override the default
+newline convention, though it is possible to set the newline convention from
+within the pattern. A warning is given if the \fBposix\fP or \fBposix_nosub\fP
+modifier is used when \fB#newline_default\fP would set a default for the
+non-POSIX API.
+.sp
+  #pattern 
+.sp
+This command sets a default modifier list that applies to all subsequent
+patterns. Modifiers on a pattern can change these settings.
+.sp
+  #perltest
+.sp
+This line is used in test files that can also be processed by \fBperltest.sh\fP
+to confirm that Perl gives the same results as PCRE2. Subsequent tests are
+checked for the use of \fBpcre2test\fP features that are incompatible with the
+\fBperltest.sh\fP script.
+.P
+Patterns must use '/' as their delimiter, and only certain modifiers are
+supported. Comment lines, #pattern commands, and #subject commands that set or
+unset "mark" are recognized and acted on. The #perltest, #forbid_utf, and
+#newline_default commands, which are needed in the relevant pcre2test files,
+are silently ignored. All other command lines are ignored, but give a warning
+message. The \fB#perltest\fP command helps detect tests that are accidentally
+put in the wrong file or use the wrong delimiter. For more details of the
+\fBperltest.sh\fP script see the comments it contains.
+.sp
+  #pop []
+  #popcopy []
+.sp
+These commands are used to manipulate the stack of compiled patterns, as
+described in the section entitled "Saving and restoring compiled patterns"
+.\" HTML 
+.\"

+.sp
+  #save

+This command is used to save a set of compiled patterns to a file, as described
+in the section entitled "Saving and restoring compiled patterns"

+.\"
+.sp
+  #subject 
+.sp
+This command sets a default modifier list that applies to all subsequent
+subject lines. Modifiers on a subject line can change these settings.
+.
+.
+.SH "MODIFIER SYNTAX"
+.rs
+.sp
+Modifier lists are used with both pattern and subject lines. Items in a list
+are separated by commas followed by optional white space. Trailing whitespace
+in a modifier list is ignored. Some modifiers may be given for both patterns
+and subject lines, whereas others are valid only for one or the other. Each
+modifier has a long name, for example "anchored", and some of them must be
+followed by an equals sign and a value, for example, "offset=12". Values cannot
+contain comma characters, but may contain spaces. Modifiers that do not take
+values may be preceded by a minus sign to turn off a previous setting.
+.P
+A few of the more common modifiers can also be specified as single letters, for
+example "i" for "caseless". In documentation, following the Perl convention,
+these are written with a slash ("the /i modifier") for clarity. Abbreviated
+modifiers must all be concatenated in the first item of a modifier list. If the
+first item is not recognized as a long modifier name, it is interpreted as a
+sequence of these abbreviations. For example:
+.sp
+  /abc/ig,newline=cr,jit=3
+.sp
+This is a pattern line whose modifier list starts with two one-letter modifiers
+(/i and /g). The lower-case abbreviated modifiers are the same as used in Perl.
+.
+.
+.SH "PATTERN SYNTAX"
+.rs
+.sp
+A pattern line must start with one of the following characters (common symbols,
+excluding pattern meta-characters):
+.sp
+  / ! " ' ` - = _ : ; , % & @ ~
+.sp
+This is interpreted as the pattern's delimiter. A regular expression may be
+continued over several input lines, in which case the newline characters are
+included within it. It is possible to include the delimiter as a literal within
+the pattern by escaping it with a backslash, for example
+.sp
+  /abc\e/def/
+.sp
+If you do this, the escape and the delimiter form part of the pattern, but
+since the delimiters are all non-alphanumeric, the inclusion of the backslash
+does not affect the pattern's interpretation. Note, however, that this trick
+does not work within \eQ...\eE literal bracketing because the backslash will
+itself be interpreted as a literal. If the terminating delimiter is immediately
+followed by a backslash, for example,
+.sp
+  /abc/\e
+.sp
+a backslash is added to the end of the pattern. This is done to provide a way
+of testing the error condition that arises if a pattern finishes with a
+backslash, because
+.sp
+  /abc\e/
+.sp
+is interpreted as the first line of a pattern that starts with "abc/", causing
+pcre2test to read the next line as a continuation of the regular expression.
+.P
+A pattern can be followed by a modifier list (details below).
+.
+.
+.SH "SUBJECT LINE SYNTAX"
+.rs
+.sp
+Before each subject line is passed to \fBpcre2_match()\fP,
+\fBpcre2_dfa_match()\fP, or \fBpcre2_jit_match()\fP, leading and trailing white
+space is removed, and the line is scanned for backslash escapes, unless the
+\fBsubject_literal\fP modifier was set for the pattern. The following provide a
+means of encoding non-printing characters in a visible way:
+.sp
+  \ea         alarm (BEL, \ex07)
+  \eb         backspace (\ex08)
+  \ee         escape (\ex27)
+  \ef         form feed (\ex0c)
+  \en         newline (\ex0a)
+  \er         carriage return (\ex0d)
+  \et         tab (\ex09)
+  \ev         vertical tab (\ex0b)
+  \ennn       octal character (up to 3 octal digits); always
+               a byte unless > 255 in UTF-8 or 16-bit or 32-bit mode
+  \eo{dd...}  octal character (any number of octal digits}
+  \exhh       hexadecimal byte (up to 2 hex digits)
+  \ex{hh...}  hexadecimal character (any number of hex digits)
+.sp
+The use of \ex{hh...} is not dependent on the use of the \fButf\fP modifier on
+the pattern. It is recognized always. There may be any number of hexadecimal
+digits inside the braces; invalid values provoke error messages.
+.P
+Note that \exhh specifies one byte rather than one character in UTF-8 mode;
+this makes it possible to construct invalid UTF-8 sequences for testing
+purposes. On the other hand, \ex{hh} is interpreted as a UTF-8 character in
+UTF-8 mode, generating more than one byte if the value is greater than 127.
+When testing the 8-bit library not in UTF-8 mode, \ex{hh} generates one byte
+for values less than 256, and causes an error for greater values.
+.P
+In UTF-16 mode, all 4-digit \ex{hhhh} values are accepted. This makes it
+possible to construct invalid UTF-16 sequences for testing purposes.
+.P
+In UTF-32 mode, all 4- to 8-digit \ex{...} values are accepted. This makes it
+possible to construct invalid UTF-32 sequences for testing purposes.
+.P
+There is a special backslash sequence that specifies replication of one or more
+characters:
+.sp
+  \e[]{}
+.sp
+This makes it possible to test long strings without having to provide them as
+part of the file. For example:
+.sp
+  \e[abc]{4}
+.sp
+is converted to "abcabcabcabc". This feature does not support nesting. To
+include a closing square bracket in the characters, code it as \ex5D.
+.P
+A backslash followed by an equals sign marks the end of the subject string and
+the start of a modifier list. For example:
+.sp
+  abc\e=notbol,notempty
+.sp
+If the subject string is empty and \e= is followed by whitespace, the line is
+treated as a comment line, and is not used for matching. For example:
+.sp
+  \e= This is a comment.
+  abc\e= This is an invalid modifier list.
+.sp
+A backslash followed by any other non-alphanumeric character just escapes that
+character. A backslash followed by anything else causes an error. However, if
+the very last character in the line is a backslash (and there is no modifier
+list), it is ignored. This gives a way of passing an empty line as data, since
+a real empty line terminates the data input.
+.P
+If the \fBsubject_literal\fP modifier is set for a pattern, all subject lines
+that follow are treated as literals, with no special treatment of backslashes.
+No replication is possible, and any subject modifiers must be set as defaults
+by a \fB#subject\fP command.
+.
+.
+.SH "PATTERN MODIFIERS"
+.rs

+brackets. Setting \fButf\fP in 16-bit or 32-bit mode also causes pattern and

+being passed to library functions.

+.sp
+The effects of these modifiers are described in the following sections.
+.
+.
+.SS "Newline and \eR handling"
+.rs
+.sp
+The \fBbsr\fP modifier specifies what \eR in a pattern should match. If it is
+set to "anycrlf", \eR matches CR, LF, or CRLF only. If it is set to "unicode",
+\eR matches any Unicode newline sequence. The default can be specified when
+PCRE2 is built; if it is not, the default is set to Unicode.
+.P
+The \fBnewline\fP modifier specifies which characters are to be interpreted as
+newlines, both in the pattern and in subject lines. The type must be one of CR,
+LF, CRLF, ANYCRLF, ANY, or NUL (in upper or lower case).
+.
+.
+.SS "Information about a pattern"
+.rs
+.sp
+The \fBdebug\fP modifier is a shorthand for \fBinfo,fullbincode\fP, requesting
+all available information.
+.P
+The \fBbincode\fP modifier causes a representation of the compiled code to be
+output after compilation. This information does not contain length and offset
+values, which ensures that the same output is generated for different internal
+link sizes and different code unit widths. By using \fBbincode\fP, the same
+regression tests can be used in different environments.
+.P
+The \fBfullbincode\fP modifier, by contrast, \fIdoes\fP include length and
+offset values. This is used in a few special tests that run only for specific
+code unit widths and link sizes, and is also useful for one-off tests.
+.P
+The \fBinfo\fP modifier requests information about the compiled pattern
+(whether it is anchored, has a fixed first character, and so on). The
+information is obtained from the \fBpcre2_pattern_info()\fP function. Here are
+some typical examples:
+.sp
+    re> /(?i)(^a|^b)/m,info
+  Capture group count = 1
+  Compile options: multiline
+  Overall options: caseless multiline
+  First code unit at start or follows newline
+  Subject length lower bound = 1
+.sp
+    re> /(?i)abc/info
+  Capture group count = 0
+  Compile options: 
+  Overall options: caseless
+  First code unit = 'a' (caseless)
+  Last code unit = 'c' (caseless)
+  Subject length lower bound = 3
+.sp
+"Compile options" are those specified by modifiers; "overall options" have
+added options that are taken or deduced from the pattern. If both sets of
+options are the same, just a single "options" line is output; if there are no
+options, the line is omitted. "First code unit" is where any match must start;
+if there is more than one they are listed as "starting code units". "Last code
+unit" is the last literal code unit that must be present in any match. This is
+not necessarily the last character. These lines are omitted if no starting or
+ending code units are recorded. The subject length line is omitted when
+\fBno_start_optimize\fP is set because the minimum length is not calculated
+when it can never be used.
+.P
+The \fBframesize\fP modifier shows the size, in bytes, of each storage frame
+used by \fBpcre2_match()\fP for handling backtracking. The size depends on the
+number of capturing parentheses in the pattern. A vector of these frames is
+used at matching time; its overall size is shown when the \fBheaframes_size\fP
+subject modifier is set.
+.P
+The \fBcallout_info\fP modifier requests information about all the callouts in
+the pattern. A list of them is output at the end of any other information that
+is requested. For each callout, either its number or string is given, followed
+by the item that follows it in the pattern.
+.
+.
+.SS "Passing a NULL context"
+.rs
+.sp
+Normally, \fBpcre2test\fP passes a context block to \fBpcre2_compile()\fP. If
+the \fBnull_context\fP modifier is set, however, NULL is passed. This is for
+testing that \fBpcre2_compile()\fP behaves correctly in this case (it uses
+default values).
+.
+.
+.SS "Passing a NULL pattern"
+.rs
+.sp
+The \fBnull_pattern\fP modifier is for testing the behaviour of
+\fBpcre2_compile()\fP when the pattern argument is NULL. The length value
+passed is the default PCRE2_ZERO_TERMINATED unless \fBuse_length\fP is set.
+Any length other than zero causes an error.
+.
+.
+.SS "Specifying pattern characters in hexadecimal"
+.rs
+.sp
+The \fBhex\fP modifier specifies that the characters of the pattern, except for
+substrings enclosed in single or double quotes, are to be interpreted as pairs
+of hexadecimal digits. This feature is provided as a way of creating patterns
+that contain binary zeros and other non-printing characters. White space is
+permitted between pairs of digits. For example, this pattern contains three
+characters:
+.sp
+  /ab 32 59/hex
+.sp
+Parts of such a pattern are taken literally if quoted. This pattern contains
+nine characters, only two of which are specified in hexadecimal:
+.sp
+  /ab "literal" 32/hex
+.sp
+Either single or double quotes may be used. There is no way of including
+the delimiter within a substring. The \fBhex\fP and \fBexpand\fP modifiers are
+mutually exclusive.
+.
+.
+.SS "Specifying the pattern's length"
+.rs
+.sp
+By default, patterns are passed to the compiling functions as zero-terminated
+strings but can be passed by length instead of being zero-terminated. The
+\fBuse_length\fP modifier causes this to happen. Using a length happens
+automatically (whether or not \fBuse_length\fP is set) when \fBhex\fP is set,
+because patterns specified in hexadecimal may contain binary zeros.
+.P
+If \fBhex\fP or \fBuse_length\fP is used with the POSIX wrapper API (see
+.\" HTML 
+.\" 
+"Using the POSIX wrapper API"
+.\"
+below), the REG_PEND extension is used to pass the pattern's length.
+.
+.
+.SS "Specifying a maximum for variable lookbehinds"
+.rs
+.sp
+Variable lookbehind assertions are supported only if, for each one, there is a
+maximum length (in characters) that it can match. There is a limit on this,
+whose default can be set at build time, with an ultimate default of 255. The
+\fBmax_varlookbehind\fP modifier uses the \fBpcre2_set_max_varlookbehind()\fP
+function to change the limit. Lookbehinds whose branches each match a fixed
+length are limited to 65535 characters per branch.
+.
+.
+.SS "Specifying wide characters in 16-bit and 32-bit modes"
+.rs
+.sp
+In 16-bit and 32-bit modes, all input is automatically treated as UTF-8 and
+translated to UTF-16 or UTF-32 when the \fButf\fP modifier is set. For testing
+the 16-bit and 32-bit libraries in non-UTF mode, the \fButf8_input\fP modifier
+can be used. It is mutually exclusive with \fButf\fP. Input lines are
+interpreted as UTF-8 as a means of specifying wide characters. More details are
+given in
+.\" HTML 
+.\" 
+"Input encoding"
+.\"
+above.
+.
+.
+.SS "Generating long repetitive patterns"
+.rs
+.sp
+Some tests use long patterns that are very repetitive. Instead of creating a
+very long input line for such a pattern, you can use a special repetition
+feature, similar to the one described for subject lines above. If the
+\fBexpand\fP modifier is present on a pattern, parts of the pattern that have
+the form
+.sp
+  \e[]{}
+.sp
+are expanded before the pattern is passed to \fBpcre2_compile()\fP. For
+example, \e[AB]{6000} is expanded to "ABAB..." 6000 times. This construction
+cannot be nested. An initial "\e[" sequence is recognized only if "]{" followed
+by decimal digits and "}" is found later in the pattern. If not, the characters
+remain in the pattern unaltered. The \fBexpand\fP and \fBhex\fP modifiers are
+mutually exclusive.
+.P
+If part of an expanded pattern looks like an expansion, but is really part of
+the actual pattern, unwanted expansion can be avoided by giving two values in
+the quantifier. For example, \e[AB]{6000,6000} is not recognized as an
+expansion item.
+.P
+If the \fBinfo\fP modifier is set on an expanded pattern, the result of the
+expansion is included in the information that is output.
+.
+.
+.SS "JIT compilation"
+.rs
+.sp
+Just-in-time (JIT) compiling is a heavyweight optimization that can greatly
+speed up pattern matching. See the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation for details. JIT compiling happens, optionally, after a pattern
+has been successfully compiled into an internal form. The JIT compiler converts
+this to optimized machine code. It needs to know whether the match-time options
+PCRE2_PARTIAL_HARD and PCRE2_PARTIAL_SOFT are going to be used, because
+different code is generated for the different cases. See the \fBpartial\fP
+modifier in "Subject Modifiers"
+.\" HTML 
+.\" 
+below
+.\"
+for details of how these options are specified for each match attempt.
+.P
+JIT compilation is requested by the \fBjit\fP pattern modifier, which may
+optionally be followed by an equals sign and a number in the range 0 to 7.
+The three bits that make up the number specify which of the three JIT operating
+modes are to be compiled:
+.sp
+  1  compile JIT code for non-partial matching
+  2  compile JIT code for soft partial matching
+  4  compile JIT code for hard partial matching
+.sp
+The possible values for the \fBjit\fP modifier are therefore:
+.sp
+  0  disable JIT
+  1  normal matching only
+  2  soft partial matching only
+  3  normal and soft partial matching
+  4  hard partial matching only
+  6  soft and hard partial matching only
+  7  all three modes
+.sp
+If no number is given, 7 is assumed. The phrase "partial matching" means a call
+to \fBpcre2_match()\fP with either the PCRE2_PARTIAL_SOFT or the
+PCRE2_PARTIAL_HARD option set. Note that such a call may return a complete
+match; the options enable the possibility of a partial match, but do not
+require it. Note also that if you request JIT compilation only for partial
+matching (for example, jit=2) but do not set the \fBpartial\fP modifier on a
+subject line, that match will not use JIT code because none was compiled for
+non-partial matching.
+.P
+If JIT compilation is successful, the compiled JIT code will automatically be
+used when an appropriate type of match is run, except when incompatible
+run-time options are specified. For more details, see the
+.\" HREF
+\fBpcre2jit\fP
+.\"
+documentation. See also the \fBjitstack\fP modifier below for a way of
+setting the size of the JIT stack.
+.P
+If the \fBjitfast\fP modifier is specified, matching is done using the JIT
+"fast path" interface, \fBpcre2_jit_match()\fP, which skips some of the sanity
+checks that are done by \fBpcre2_match()\fP, and of course does not work when
+JIT is not supported. If \fBjitfast\fP is specified without \fBjit\fP, jit=7 is
+assumed.
+.P
+If the \fBjitverify\fP modifier is specified, information about the compiled
+pattern shows whether JIT compilation was or was not successful. If
+\fBjitverify\fP is specified without \fBjit\fP, jit=7 is assumed. If JIT
+compilation is successful when \fBjitverify\fP is set, the text "(JIT)" is
+added to the first output line after a match or non match when JIT-compiled
+code was actually used in the match.
+.
+.
+.SS "Setting a locale"
+.rs
+.sp
+The \fBlocale\fP modifier must specify the name of a locale, for example:
+.sp
+  /pattern/locale=fr_FR
+.sp
+The given locale is set, \fBpcre2_maketables()\fP is called to build a set of
+character tables for the locale, and this is then passed to
+\fBpcre2_compile()\fP when compiling the regular expression. The same tables
+are used when matching the following subject lines. The \fBlocale\fP modifier
+applies only to the pattern on which it appears, but can be given in a
+\fB#pattern\fP command if a default is needed. Setting a locale and alternate
+character tables are mutually exclusive.
+.
+.
+.SS "Showing pattern memory"
+.rs
+.sp
+The \fBmemory\fP modifier causes the size in bytes of the memory used to hold
+the compiled pattern to be output. This does not include the size of the
+\fBpcre2_code\fP block; it is just the actual compiled data. If the pattern is
+subsequently passed to the JIT compiler, the size of the JIT compiled code is
+also output. Here is an example:
+.sp
+    re> /a(b)c/jit,memory
+  Memory allocation (code space): 21
+  Memory allocation (JIT code): 1910
+.sp
+.
+.
+.SS "Limiting nested parentheses"
+.rs
+.sp
+The \fBparens_nest_limit\fP modifier sets a limit on the depth of nested
+parentheses in a pattern. Breaching the limit causes a compilation error.
+The default for the library is set when PCRE2 is built, but \fBpcre2test\fP
+sets its own default of 220, which is required for running the standard test
+suite.
+.
+.
+.SS "Limiting the pattern length"
+.rs
+.sp
+The \fBmax_pattern_length\fP modifier sets a limit, in code units, to the
+length of pattern that \fBpcre2_compile()\fP will accept. Breaching the limit
+causes a compilation error. The default is the largest number a PCRE2_SIZE
+variable can hold (essentially unlimited).
+.
+.
+.SS "Limiting the size of a compiled pattern"
+.rs
+.sp
+The \fBmax_pattern_compiled_length\fP modifier sets a limit, in bytes, to the
+amount of memory used by a compiled pattern. Breaching the limit causes a
+compilation error. The default is the largest number a PCRE2_SIZE variable can
+hold (essentially unlimited).
+.
+.
+.\" HTML 
+.SS "Using the POSIX wrapper API"
+.rs
+.sp
+The \fBposix\fP and \fBposix_nosub\fP modifiers cause \fBpcre2test\fP to call
+PCRE2 via the POSIX wrapper API rather than its native API. When
+\fBposix_nosub\fP is used, the POSIX option REG_NOSUB is passed to
+\fBregcomp()\fP. The POSIX wrapper supports only the 8-bit library. Note that
+it does not imply POSIX matching semantics; for more detail see the
+.\" HREF
+\fBpcre2posix\fP
+.\"
+documentation. The following pattern modifiers set options for the
+\fBregcomp()\fP function:
+.sp
+  caseless           REG_ICASE
+  multiline          REG_NEWLINE
+  dotall             REG_DOTALL     )
+  ungreedy           REG_UNGREEDY   ) These options are not part of
+  ucp                REG_UCP        )   the POSIX standard
+  utf                REG_UTF8       )
+.sp
+The \fBregerror_buffsize\fP modifier specifies a size for the error buffer that
+is passed to \fBregerror()\fP in the event of a compilation error. For example:
+.sp
+  /abc/posix,regerror_buffsize=20
+.sp
+This provides a means of testing the behaviour of \fBregerror()\fP when the
+buffer is too small for the error message. If this modifier has not been set, a
+large buffer is used.
+.P
+The \fBaftertext\fP and \fBallaftertext\fP subject modifiers work as described
+below. All other modifiers are either ignored, with a warning message, or cause
+an error.
+.P
+The pattern is passed to \fBregcomp()\fP as a zero-terminated string by
+default, but if the \fBuse_length\fP or \fBhex\fP modifiers are set, the
+REG_PEND extension is used to pass it by length.
+.
+.
+.SS "Testing the stack guard feature"
+.rs
+.sp
+The \fBstackguard\fP modifier is used to test the use of
+\fBpcre2_set_compile_recursion_guard()\fP, a function that is provided to
+enable stack availability to be checked during compilation (see the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation for details). If the number specified by the modifier is greater
+than zero, \fBpcre2_set_compile_recursion_guard()\fP is called to set up
+callback from \fBpcre2_compile()\fP to a local function. The argument it
+receives is the current nesting parenthesis depth; if this is greater than the
+value given by the modifier, non-zero is returned, causing the compilation to
+be aborted.
+.
+.
+.SS "Using alternative character tables"
+.rs
+.sp
+The value specified for the \fBtables\fP modifier must be one of the digits 0,
+1, 2, or 3. It causes a specific set of built-in character tables to be passed
+to \fBpcre2_compile()\fP. This is used in the PCRE2 tests to check behaviour
+with different character tables. The digit specifies the tables as follows:
+.sp
+  0   do not pass any special character tables
+  1   the default ASCII tables, as distributed in
+        pcre2_chartables.c.dist
+  2   a set of tables defining ISO 8859 characters
+  3   a set of tables loaded by the #loadtables command
+.sp
+In tables 2, some characters whose codes are greater than 128 are identified as
+letters, digits, spaces, etc. Tables 3 can be used only after a
+\fB#loadtables\fP command has loaded them from a binary file. Setting alternate
+character tables and a locale are mutually exclusive.
+.
+.
+.SS "Setting certain match controls"
+.rs
+.sp
+The following modifiers are really subject modifiers, and are described under
+"Subject Modifiers" below. However, they may be included in a pattern's
+modifier list, in which case they are applied to every subject line that is
+processed with that pattern. These modifiers do not affect the compilation

+These modifiers may not appear in a \fB#pattern\fP command. If you want them as

+.
+.
+.SS "Specifying literal subject lines"
+.rs
+.sp
+If the \fBsubject_literal\fP modifier is present on a pattern, all the subject
+lines that it matches are taken as literal strings, with no interpretation of
+backslashes. It is not possible to set subject modifiers on such lines, but any
+that are set as defaults by a \fB#subject\fP command are recognized.
+.
+.
+.SS "Saving a compiled pattern"
+.rs
+.sp
+When a pattern with the \fBpush\fP modifier is successfully compiled, it is
+pushed onto a stack of compiled patterns, and \fBpcre2test\fP expects the next
+line to contain a new pattern (or a command) instead of a subject line. This
+facility is used when saving compiled patterns to a file, as described in the
+section entitled "Saving and restoring compiled patterns"
+.\" HTML 
+.\" 
+below.
+.\"
+If \fBpushcopy\fP is used instead of \fBpush\fP, a copy of the compiled
+pattern is stacked, leaving the original as current, ready to match the
+following input lines. This provides a way of testing the
+\fBpcre2_code_copy()\fP function.
+.\"
+The \fBpush\fP and \fBpushcopy \fP modifiers are incompatible with compilation
+modifiers such as \fBglobal\fP that act at match time. Any that are specified
+are ignored (for the stacked copy), with a warning message, except for
+\fBreplace\fP, which causes an error. Note that \fBjitverify\fP, which is
+allowed, does not carry through to any subsequent matching that uses a stacked
+pattern.
+.
+.
+.SS "Testing foreign pattern conversion"
+.rs
+.sp
+The experimental foreign pattern conversion functions in PCRE2 can be tested by
+setting the \fBconvert\fP modifier. Its argument is a colon-separated list of
+options, which set the equivalent option for the \fBpcre2_pattern_convert()\fP
+function:
+.sp
+  glob                    PCRE2_CONVERT_GLOB
+  glob_no_starstar        PCRE2_CONVERT_GLOB_NO_STARSTAR

+  posix_extended          PCRE2_CONVERT_POSIX_EXTENDED
+  unset                   Unset all options
+.sp
+The "unset" value is useful for turning off a default that has been set by a
+\fB#pattern\fP command. When one of these options is set, the input pattern is
+passed to \fBpcre2_pattern_convert()\fP. If the conversion is successful, the
+result is reflected in the output and then passed to \fBpcre2_compile()\fP. The
+normal \fButf\fP and \fBno_utf_check\fP options, if set, cause the
+PCRE2_CONVERT_UTF and PCRE2_CONVERT_NO_UTF_CHECK options to be passed to
+\fBpcre2_pattern_convert()\fP.
+.P
+By default, the conversion function is allowed to allocate a buffer for its
+output. However, if the \fBconvert_length\fP modifier is set to a value greater
+than zero, \fBpcre2test\fP passes a buffer of the given length. This makes it
+possible to test the length check.
+.P
+The \fBconvert_glob_escape\fP and \fBconvert_glob_separator\fP modifiers can be
+used to specify the escape and separator characters for glob processing,
+overriding the defaults, which are operating-system dependent.

+causing REG_NOTBOL, REG_NOTEMPTY, and REG_NOTEOL, respectively, to be passed to
+\fBregexec()\fP. The other modifiers are ignored, with a warning message.
+.P
+There is one additional modifier that can be used with the POSIX wrapper. It is
+ignored (with a warning) if used for non-POSIX matching.
+.sp
+      posix_startend=[:]
+.sp
+This causes the subject string to be passed to \fBregexec()\fP using the
+REG_STARTEND option, which uses offsets to specify which part of the string is
+searched. If only one number is given, the end offset is passed as the end of
+the subject string. For more detail of REG_STARTEND, see the
+.\" HREF
+\fBpcre2posix\fP

+documentation. If the subject string contains binary zeros (coded as escapes
+such as \ex{00} because \fBpcre2test\fP does not support actual binary zeros in

+.sp
+The effects of these modifiers are described in the following sections. When
+matching via the POSIX wrapper API, the \fBaftertext\fP, \fBallaftertext\fP,
+and \fBovector\fP subject modifiers work as described below. All other
+modifiers are either ignored, with a warning message, or cause an error.
+.
+.
+.SS "Showing more text"
+.rs
+.sp
+The \fBaftertext\fP modifier requests that as well as outputting the part of
+the subject string that matched the entire pattern, \fBpcre2test\fP should in
+addition output the remainder of the subject string. This is useful for tests
+where the subject contains multiple copies of the same substring. The
+\fBallaftertext\fP modifier requests the same action for captured substrings as
+well as the main matched substring. In each case the remainder is output on the
+following line with a plus character following the capture number.
+.P
+The \fBallusedtext\fP modifier requests that all the text that was consulted
+during a successful pattern match by the interpreter should be shown, for both
+full and partial matches. This feature is not supported for JIT matching, and
+if requested with JIT it is ignored (with a warning message). Setting this
+modifier affects the output if there is a lookbehind at the start of a match,
+or, for a complete match, a lookahead at the end, or if \eK is used in the
+pattern. Characters that precede or follow the start and end of the actual
+match are indicated in the output by '<' or '>' characters underneath them.
+Here is an example:
+.sp
+    re> /(?<=pqr)abc(?=xyz)/
+  data> 123pqrabcxyz456\e=allusedtext
+   0: pqrabcxyz
+      <<<   >>>
+  data> 123pqrabcxy\e=ph,allusedtext
+  Partial match: pqrabcxy
+                 <<<
+.sp
+The first, complete match shows that the matched string is "abc", with the
+preceding and following strings "pqr" and "xyz" having been consulted during
+the match (when processing the assertions). The partial match can indicate only
+the preceding string.
+.P
+The \fBstartchar\fP modifier requests that the starting character for the match
+be indicated, if it is different to the start of the matched string. The only
+time when this occurs is when \eK has been processed as part of the match. In
+this situation, the output for the matched string is displayed from the
+starting character instead of from the match point, with circumflex characters
+under the earlier characters. For example:
+.sp
+    re> /abc\eKxyz/
+  data> abcxyz\e=startchar
+   0: abcxyz
+      ^^^
+.sp
+Unlike \fBallusedtext\fP, the \fBstartchar\fP modifier can be used with JIT.
+However, these two modifiers are mutually exclusive.
+.
+.
+.SS "Showing the value of all capture groups"
+.rs
+.sp
+The \fBallcaptures\fP modifier requests that the values of all potential
+captured parentheses be output after a match. By default, only those up to the
+highest one actually used in the match are output (corresponding to the return
+code from \fBpcre2_match()\fP). Groups that did not take part in the match
+are output as "". This modifier is not relevant for DFA matching (which
+does no capturing) and does not apply when \fBreplace\fP is specified; it is
+ignored, with a warning message, if present.
+.
+.
+.SS "Showing the entire ovector, for all outcomes"
+.rs
+.sp
+The \fBallvector\fP modifier requests that the entire ovector be shown,
+whatever the outcome of the match. Compare \fBallcaptures\fP, which shows only
+up to the maximum number of capture groups for the pattern, and then only for a
+successful complete non-DFA match. This modifier, which acts after any match
+result, and also for DFA matching, provides a means of checking that there are
+no unexpected modifications to ovector fields. Before each match attempt, the
+ovector is filled with a special value, and if this is found in both elements
+of a capturing pair, "" is output. After a successful match, this
+applies to all groups after the maximum capture group for the pattern. In other
+cases it applies to the entire ovector. After a partial match, the first two
+elements are the only ones that should be set. After a DFA match, the amount of
+ovector that is used depends on the number of matches that were found.
+.
+.
+.SS "Testing pattern callouts"
+.rs
+.sp
+A callout function is supplied when \fBpcre2test\fP calls the library matching
+functions, unless \fBcallout_none\fP is specified. Its behaviour can be
+controlled by various modifiers listed above whose names begin with
+\fBcallout_\fP. Details are given in the section entitled "Callouts"
+.\" HTML 
+.\" 
+below.
+.\"
+Testing callouts from \fBpcre2_substitute()\fP is described separately in
+"Testing the substitution function"
+.\" HTML 
+.\" 
+below.
+.\"
+.
+.
+.SS "Finding all matches in a string"
+.rs
+.sp
+Searching for all possible matches within a subject can be requested by the
+\fBglobal\fP or \fBaltglobal\fP modifier. After finding a match, the matching
+function is called again to search the remainder of the subject. The difference
+between \fBglobal\fP and \fBaltglobal\fP is that the former uses the
+\fIstart_offset\fP argument to \fBpcre2_match()\fP or \fBpcre2_dfa_match()\fP
+to start searching at a new point within the entire string (which is what Perl
+does), whereas the latter passes over a shortened subject. This makes a
+difference to the matching process if the pattern begins with a lookbehind
+assertion (including \eb or \eB).
+.P
+If an empty string is matched, the next match is done with the
+PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set, in order to search for
+another, non-empty, match at the same point in the subject. If this match
+fails, the start offset is advanced, and the normal match is retried. This
+imitates the way Perl handles such cases when using the \fB/g\fP modifier or
+the \fBsplit()\fP function. Normally, the start offset is advanced by one
+character, but if the newline convention recognizes CRLF as a newline, and the
+current character is CR followed by LF, an advance of two characters occurs.
+.
+.
+.SS "Testing substring extraction functions"
+.rs
+.sp
+The \fBcopy\fP and \fBget\fP modifiers can be used to test the
+\fBpcre2_substring_copy_xxx()\fP and \fBpcre2_substring_get_xxx()\fP functions.
+They can be given more than once, and each can specify a capture group name or
+number, for example:
+.sp
+   abcd\e=copy=1,copy=3,get=G1
+.sp
+If the \fB#subject\fP command is used to set default copy and/or get lists,
+these can be unset by specifying a negative number to cancel all numbered
+groups and an empty name to cancel all named groups.
+.P
+The \fBgetall\fP modifier tests \fBpcre2_substring_list_get()\fP, which
+extracts all captured substrings.
+.P
+If the subject line is successfully matched, the substrings extracted by the
+convenience functions are output with C, G, or L after the string number
+instead of a colon. This is in addition to the normal full list. The string
+length (that is, the return from the extraction function) is given in
+parentheses after each substring, followed by the name when the extraction was
+by name.
+.
+.
+.\" HTML 
+.SS "Testing the substitution function"
+.rs
+.sp
+If the \fBreplace\fP modifier is set, the \fBpcre2_substitute()\fP function is
+called instead of one of the matching functions (or after one call of
+\fBpcre2_match()\fP in the case of PCRE2_SUBSTITUTE_MATCHED). Note that
+replacement strings cannot contain commas, because a comma signifies the end of
+a modifier. This is not thought to be an issue in a test program.
+.P
+Specifying a completely empty replacement string disables this modifier.
+However, it is possible to specify an empty replacement by providing a buffer
+length, as described below, for an otherwise empty replacement.
+.P
+Unlike subject strings, \fBpcre2test\fP does not process replacement strings
+for escape sequences. In UTF mode, a replacement string is checked to see if it
+is a valid UTF-8 string. If so, it is correctly converted to a UTF string of
+the appropriate code unit width. If it is not a valid UTF-8 string, the
+individual code units are copied directly. This provides a means of passing an
+invalid UTF-8 string for testing purposes.
+.P
+The following modifiers set options (in additional to the normal match options)
+for \fBpcre2_substitute()\fP:
+.sp
+  global                      PCRE2_SUBSTITUTE_GLOBAL
+  substitute_extended         PCRE2_SUBSTITUTE_EXTENDED
+  substitute_literal          PCRE2_SUBSTITUTE_LITERAL
+  substitute_matched          PCRE2_SUBSTITUTE_MATCHED
+  substitute_overflow_length  PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+  substitute_replacement_only PCRE2_SUBSTITUTE_REPLACEMENT_ONLY
+  substitute_unknown_unset    PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+  substitute_unset_empty      PCRE2_SUBSTITUTE_UNSET_EMPTY
+.sp
+See the
+.\" HREF
+\fBpcre2api\fP
+.\"
+documentation for details of these options.
+.P
+After a successful substitution, the modified string is output, preceded by the
+number of replacements. This may be zero if there were no matches. Here is a
+simple example of a substitution test:
+.sp
+  /abc/replace=xxx
+      =abc=abc=
+   1: =xxx=abc=
+      =abc=abc=\e=global
+   2: =xxx=xxx=
+.sp
+Subject and replacement strings should be kept relatively short (fewer than 256
+characters) for substitution tests, as fixed-size buffers are used. To make it
+easy to test for buffer overflow, if the replacement string starts with a
+number in square brackets, that number is passed to \fBpcre2_substitute()\fP as
+the size of the output buffer, with the replacement string starting at the next
+character. Here is an example that tests the edge case:
+.sp
+  /abc/
+      123abc123\e=replace=[10]XYZ
+   1: 123XYZ123
+      123abc123\e=replace=[9]XYZ
+  Failed: error -47: no more memory
+.sp
+The default action of \fBpcre2_substitute()\fP is to return
+PCRE2_ERROR_NOMEMORY when the output buffer is too small. However, if the
+PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option is set (by using the
+\fBsubstitute_overflow_length\fP modifier), \fBpcre2_substitute()\fP continues
+to go through the motions of matching and substituting (but not doing any
+callouts), in order to compute the size of buffer that is required. When this
+happens, \fBpcre2test\fP shows the required buffer length (which includes space
+for the trailing zero) as part of the error message. For example:
+.sp
+  /abc/substitute_overflow_length
+      123abc123\e=replace=[9]XYZ
+  Failed: error -47: no more memory: 10 code units are needed
+.sp
+A replacement string is ignored with POSIX and DFA matching. Specifying partial
+matching provokes an error return ("bad option value") from
+\fBpcre2_substitute()\fP.
+.
+.
+.SS "Testing substitute callouts"
+.rs
+.sp
+If the \fBsubstitute_callout\fP modifier is set, a substitution callout
+function is set up. The \fBnull_context\fP modifier must not be set, because
+the address of the callout function is passed in a match context. When the
+callout function is called (after each substitution), details of the input
+and output strings are output. For example:
+.sp
+  /abc/g,replace=<$0>,substitute_callout
+      abcdefabcpqr
+   1(1) Old 0 3 "abc" New 0 5 ""
+   2(1) Old 6 9 "abc" New 8 13 ""
+   2: defpqr
+.sp
+The first number on each callout line is the count of matches. The
+parenthesized number is the number of pairs that are set in the ovector (that
+is, one more than the number of capturing groups that were set). Then are
+listed the offsets of the old substring, its contents, and the same for the
+replacement.
+.P
+By default, the substitution callout function returns zero, which accepts the
+replacement and causes matching to continue if /g was used. Two further
+modifiers can be used to test other return values. If \fBsubstitute_skip\fP is
+set to a value greater than zero the callout function returns +1 for the match
+of that number, and similarly \fBsubstitute_stop\fP returns -1. These cause the
+replacement to be rejected, and -1 causes no further matching to take place. If
+either of them are set, \fBsubstitute_callout\fP is assumed. For example:
+.sp
+  /abc/g,replace=<$0>,substitute_skip=1
+      abcdefabcpqr
+   1(1) Old 0 3 "abc" New 0 5 " SKIPPED"
+   2(1) Old 6 9 "abc" New 6 11 ""
+   2: abcdefpqr
+      abcdefabcpqr\e=substitute_stop=1
+   1(1) Old 0 3 "abc" New 0 5 " STOPPED"
+   1: abcdefabcpqr
+.sp
+If both are set for the same number, stop takes precedence. Only a single skip
+or stop is supported, which is sufficient for testing that the feature works.
+.
+.
+.SS "Setting the JIT stack size"
+.rs
+.sp
+The \fBjitstack\fP modifier provides a way of setting the maximum stack size
+that is used by the just-in-time optimization code. It is ignored if JIT
+optimization is not being used. The value is a number of kibibytes (units of
+1024 bytes). Setting zero reverts to the default of 32KiB. Providing a stack
+that is larger than the default is necessary only for very complicated
+patterns. If \fBjitstack\fP is set non-zero on a subject line it overrides any
+value that was set on the pattern.
+.
+.
+.SS "Setting heap, match, and depth limits"
+.rs
+.sp
+The \fBheap_limit\fP, \fBmatch_limit\fP, and \fBdepth_limit\fP modifiers set
+the appropriate limits in the match context. These values are ignored when the
+\fBfind_limits\fP or \fBfind_limits_noheap\fP modifier is specified.
+.
+.
+.SS "Finding minimum limits"
+.rs
+.sp
+If the \fBfind_limits\fP modifier is present on a subject line, \fBpcre2test\fP
+calls the relevant matching function several times, setting different values in
+the match context via \fBpcre2_set_heap_limit()\fP,
+\fBpcre2_set_match_limit()\fP, or \fBpcre2_set_depth_limit()\fP until it finds
+the smallest value for each parameter that allows the match to complete without
+a "limit exceeded" error. The match itself may succeed or fail. An alternative
+modifier, \fBfind_limits_noheap\fP, omits the heap limit. This is used in the
+standard tests, because the minimum heap limit varies between systems. If JIT
+is being used, only the match limit is relevant, and the other two are
+automatically omitted.
+.P
+When using this modifier, the pattern should not contain any limit settings
+such as (*LIMIT_MATCH=...) within it. If such a setting is present and is
+lower than the minimum matching value, the minimum value cannot be found
+because \fBpcre2_set_match_limit()\fP etc. are only able to reduce the value of
+an in-pattern limit; they cannot increase it.
+.P
+For non-DFA matching, the minimum \fIdepth_limit\fP number is a measure of how
+much nested backtracking happens (that is, how deeply the pattern's tree is
+searched). In the case of DFA matching, \fIdepth_limit\fP controls the depth of
+recursive calls of the internal function that is used for handling pattern
+recursion, lookaround assertions, and atomic groups.
+.P
+For non-DFA matching, the \fImatch_limit\fP number is a measure of the amount
+of backtracking that takes place, and learning the minimum value can be
+instructive. For most simple matches, the number is quite small, but for
+patterns with very large numbers of matching possibilities, it can become large
+very quickly with increasing length of subject string. In the case of DFA
+matching, \fImatch_limit\fP controls the total number of calls, both recursive
+and non-recursive, to the internal matching function, thus controlling the
+overall amount of computing resource that is used.
+.P
+For both kinds of matching, the \fIheap_limit\fP number, which is in kibibytes
+(units of 1024 bytes), limits the amount of heap memory used for matching.
+.
+.
+.SS "Showing MARK names"
+.rs
+.sp
+.P
+The \fBmark\fP modifier causes the names from backtracking control verbs that
+are returned from calls to \fBpcre2_match()\fP to be displayed. If a mark is
+returned for a match, non-match, or partial match, \fBpcre2test\fP shows it.
+For a match, it is on a line by itself, tagged with "MK:". Otherwise, it
+is added to the non-match message.
+.
+.
+.SS "Showing memory usage"
+.rs
+.sp
+The \fBmemory\fP modifier causes \fBpcre2test\fP to log the sizes of all heap
+memory allocation and freeing calls that occur during a call to
+\fBpcre2_match()\fP or \fBpcre2_dfa_match()\fP. In the latter case, heap memory
+is used only when a match requires more internal workspace that the default
+allocation on the stack, so in many cases there will be no output. No heap
+memory is allocated during matching with JIT. For this modifier to work, the
+\fBnull_context\fP modifier must not be set on both the pattern and the
+subject, though it can be set on one or the other.
+.
+.
+.SS "Showing the heap frame overall vector size"
+.rs
+.sp
+The \fBheapframes_size\fP modifier is relevant for matches using
+\fBpcre2_match()\fP without JIT. After a match has run (whether successful or
+not) the size, in bytes, of the allocated heap frames vector that is left
+attached to the match data block is shown. If the matching action involved
+several calls to \fBpcre2_match()\fP (for example, global matching or for
+timing) only the final value is shown.
+.P
+This modifier is ignored, with a warning, for POSIX or DFA matching. JIT
+matching does not use the heap frames vector, so the size is always zero,
+unless there was a previous non-JIT match. Note that specifing a size of zero
+for the output vector (see below) causes \fBpcre2test\fP to free its match data
+block (and associated heap frames vector) and allocate a new one.
+.
+.
+.SS "Setting a starting offset"
+.rs
+.sp
+The \fBoffset\fP modifier sets an offset in the subject string at which
+matching starts. Its value is a number of code units, not characters.
+.
+.
+.SS "Setting an offset limit"
+.rs
+.sp
+The \fBoffset_limit\fP modifier sets a limit for unanchored matches. If a match
+cannot be found starting at or before this offset in the subject, a "no match"
+return is given. The data value is a number of code units, not characters. When
+this modifier is used, the \fBuse_offset_limit\fP modifier must have been set
+for the pattern; if not, an error is generated.
+.
+.
+.SS "Setting the size of the output vector"
+.rs
+.sp
+The \fBovector\fP modifier applies only to the subject line in which it
+appears, though of course it can also be used to set a default in a
+\fB#subject\fP command. It specifies the number of pairs of offsets that are
+available for storing matching information. The default is 15.
+.P
+A value of zero is useful when testing the POSIX API because it causes
+\fBregexec()\fP to be called with a NULL capture vector. When not testing the
+POSIX API, a value of zero is used to cause
+\fBpcre2_match_data_create_from_pattern()\fP to be called, in order to create a
+new match block of exactly the right size for the pattern. (It is not possible
+to create a match block with a zero-length ovector; there is always at least
+one pair of offsets.) The old match data block is freed.
+.
+.
+.SS "Passing the subject as zero-terminated"
+.rs
+.sp
+By default, the subject string is passed to a native API matching function with
+its correct length. In order to test the facility for passing a zero-terminated
+string, the \fBzero_terminate\fP modifier is provided. It causes the length to
+be passed as PCRE2_ZERO_TERMINATED. When matching via the POSIX interface,
+this modifier is ignored, with a warning.
+.P
+When testing \fBpcre2_substitute()\fP, this modifier also has the effect of
+passing the replacement string as zero-terminated.
+.
+.
+.SS "Passing a NULL context, subject, or replacement"
+.rs
+.sp
+Normally, \fBpcre2test\fP passes a context block to \fBpcre2_match()\fP,
+\fBpcre2_dfa_match()\fP, \fBpcre2_jit_match()\fP or \fBpcre2_substitute()\fP.
+If the \fBnull_context\fP modifier is set, however, NULL is passed. This is for
+testing that the matching and substitution functions behave correctly in this
+case (they use default values). This modifier cannot be used with the
+\fBfind_limits\fP, \fBfind_limits_noheap\fP, or \fBsubstitute_callout\fP
+modifiers.
+.P
+Similarly, for testing purposes, if the \fBnull_subject\fP or
+\fBnull_replacement\fP modifier is set, the subject or replacement string
+pointers are passed as NULL, respectively, to the relevant functions.
+.
+.
+.SH "THE ALTERNATIVE MATCHING FUNCTION"
+.rs
+.sp
+By default, \fBpcre2test\fP uses the standard PCRE2 matching function,
+\fBpcre2_match()\fP to match each subject line. PCRE2 also supports an
+alternative matching function, \fBpcre2_dfa_match()\fP, which operates in a
+different way, and has some restrictions. The differences between the two
+functions are described in the
+.\" HREF
+\fBpcre2matching\fP
+.\"
+documentation.
+.P
+If the \fBdfa\fP modifier is set, the alternative matching function is used.
+This function finds all possible matches at a given point in the subject. If,
+however, the \fBdfa_shortest\fP modifier is set, processing stops after the
+first match is found. This is always the shortest possible match.
+.
+.
+.SH "DEFAULT OUTPUT FROM pcre2test"
+.rs
+.sp
+This section describes the output when the normal matching function,
+\fBpcre2_match()\fP, is being used.
+.P
+When a match succeeds, \fBpcre2test\fP outputs the list of captured substrings,
+starting with number 0 for the string that matched the whole pattern.
+Otherwise, it outputs "No match" when the return is PCRE2_ERROR_NOMATCH, or
+"Partial match:" followed by the partially matching substring when the
+return is PCRE2_ERROR_PARTIAL. (Note that this is the
+entire substring that was inspected during the partial match; it may include
+characters before the actual match start if a lookbehind assertion, \eK, \eb,
+or \eB was involved.)
+.P
+For any other return, \fBpcre2test\fP outputs the PCRE2 negative error number
+and a short descriptive phrase. If the error is a failed UTF string check, the
+code unit offset of the start of the failing character is also output. Here is
+an example of an interactive \fBpcre2test\fP run.
+.sp
+  $ pcre2test
+  PCRE2 version 10.22 2016-07-29
+.sp
+    re> /^abc(\ed+)/
+  data> abc123
+   0: abc123
+   1: 123
+  data> xyz
+  No match
+.sp
+Unset capturing substrings that are not followed by one that is set are not
+shown by \fBpcre2test\fP unless the \fBallcaptures\fP modifier is specified. In
+the following example, there are two capturing substrings, but when the first
+data line is matched, the second, unset substring is not shown. An "internal"
+unset substring is shown as "", as for the second data line.
+.sp
+    re> /(a)|(b)/
+  data> a
+   0: a
+   1: a
+  data> b
+   0: b
+   1: 
+   2: b
+.sp
+If the strings contain any non-printing characters, they are output as \exhh
+escapes if the value is less than 256 and UTF mode is not set. Otherwise they
+are output as \ex{hh...} escapes. See below for the definition of non-printing
+characters. If the \fBaftertext\fP modifier is set, the output for substring 0
+is followed by the rest of the subject string, identified by "0+" like this:
+.sp
+    re> /cat/aftertext
+  data> cataract
+   0: cat
+   0+ aract
+.sp
+If global matching is requested, the results of successive matching attempts
+are output in sequence, like this:
+.sp
+    re> /\eBi(\ew\ew)/g
+  data> Mississippi
+   0: iss
+   1: ss
+   0: iss
+   1: ss
+   0: ipp
+   1: pp
+.sp
+"No match" is output only if the first match attempt fails. Here is an example
+of a failure message (the offset 4 that is specified by the \fBoffset\fP
+modifier is past the end of the subject string):
+.sp
+    re> /xyz/
+  data> xyz\e=offset=4
+  Error -24 (bad offset value)
+.P
+Note that whereas patterns can be continued over several lines (a plain ">"
+prompt is used for continuations), subject lines may not. However newlines can
+be included in a subject by means of the \en escape (or \er, \er\en, etc.,
+depending on the newline sequence setting).
+.
+.
+.
+.SH "OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION"
+.rs
+.sp
+When the alternative matching function, \fBpcre2_dfa_match()\fP, is used, the
+output consists of a list of all the matches that start at the first point in
+the subject where there is at least one match. For example:
+.sp
+    re> /(tang|tangerine|tan)/
+  data> yellow tangerine\e=dfa
+   0: tangerine
+   1: tang
+   2: tan
+.sp
+Using the normal matching function on this data finds only "tang". The
+longest matching string is always given first (and numbered zero). After a
+PCRE2_ERROR_PARTIAL return, the output is "Partial match:", followed by the
+partially matching substring. Note that this is the entire substring that was
+inspected during the partial match; it may include characters before the actual
+match start if a lookbehind assertion, \eb, or \eB was involved. (\eK is not
+supported for DFA matching.)
+.P
+If global matching is requested, the search for further matches resumes
+at the end of the longest match. For example:
+.sp
+    re> /(tang|tangerine|tan)/g
+  data> yellow tangerine and tangy sultana\e=dfa
+   0: tangerine
+   1: tang
+   2: tan
+   0: tang
+   1: tan
+   0: tan
+.sp
+The alternative matching function does not support substring capture, so the
+modifiers that are concerned with captured substrings are not relevant.
+.
+.
+.SH "RESTARTING AFTER A PARTIAL MATCH"
+.rs
+.sp
+When the alternative matching function has given the PCRE2_ERROR_PARTIAL
+return, indicating that the subject partially matched the pattern, you can
+restart the match with additional subject data by means of the
+\fBdfa_restart\fP modifier. For example:
+.sp
+    re> /^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$/
+  data> 23ja\e=ps,dfa
+  Partial match: 23ja
+  data> n05\e=dfa,dfa_restart
+   0: n05
+.sp
+For further information about partial matching, see the
+.\" HREF
+\fBpcre2partial\fP
+.\"
+documentation.
+.
+.
+.\" HTML 
+.SH CALLOUTS
+.rs
+.sp
+If the pattern contains any callout requests, \fBpcre2test\fP's callout
+function is called during matching unless \fBcallout_none\fP is specified. This
+works with both matching functions, and with JIT, though there are some
+differences in behaviour. The output for callouts with numerical arguments and
+those with string arguments is slightly different.
+.
+.
+.SS "Callouts with numerical arguments"
+.rs
+.sp
+By default, the callout function displays the callout number, the start and
+current positions in the subject text at the callout time, and the next pattern
+item to be tested. For example:
+.sp
+  --->pqrabcdef
+    0    ^  ^     \ed
+.sp
+This output indicates that callout number 0 occurred for a match attempt
+starting at the fourth character of the subject string, when the pointer was at
+the seventh character, and when the next pattern item was \ed. Just
+one circumflex is output if the start and current positions are the same, or if
+the current position precedes the start position, which can happen if the
+callout is in a lookbehind assertion.
+.P
+Callouts numbered 255 are assumed to be automatic callouts, inserted as a
+result of the \fBauto_callout\fP pattern modifier. In this case, instead of
+showing the callout number, the offset in the pattern, preceded by a plus, is
+output. For example:
+.sp
+    re> /\ed?[A-E]\e*/auto_callout
+  data> E*
+  --->E*
+   +0 ^      \ed?
+   +3 ^      [A-E]
+   +8 ^^     \e*
+  +10 ^ ^
+   0: E*
+.sp
+If a pattern contains (*MARK) items, an additional line is output whenever
+a change of latest mark is passed to the callout function. For example:
+.sp
+    re> /a(*MARK:X)bc/auto_callout
+  data> abc
+  --->abc
+   +0 ^       a
+   +1 ^^      (*MARK:X)
+  +10 ^^      b
+  Latest Mark: X
+  +11 ^ ^     c
+  +12 ^  ^
+   0: abc
+.sp
+The mark changes between matching "a" and "b", but stays the same for the rest
+of the match, so nothing more is output. If, as a result of backtracking, the
+mark reverts to being unset, the text "" is output.
+.
+.
+.SS "Callouts with string arguments"
+.rs
+.sp
+The output for a callout with a string argument is similar, except that instead
+of outputting a callout number before the position indicators, the callout
+string and its offset in the pattern string are output before the reflection of
+the subject string, and the subject string is reflected for each callout. For
+example:
+.sp
+    re> /^ab(?C'first')cd(?C"second")ef/
+  data> abcdefg
+  Callout (7): 'first'
+  --->abcdefg
+      ^ ^         c
+  Callout (20): "second"
+  --->abcdefg
+      ^   ^       e
+   0: abcdef
+.sp
+.
+.
+.SS "Callout modifiers"
+.rs
+.sp
+The callout function in \fBpcre2test\fP returns zero (carry on matching) by
+default, but you can use a \fBcallout_fail\fP modifier in a subject line to
+change this and other parameters of the callout (see below).
+.P
+If the \fBcallout_capture\fP modifier is set, the current captured groups are
+output when a callout occurs. This is useful only for non-DFA matching, as
+\fBpcre2_dfa_match()\fP does not support capturing, so no captures are ever
+shown.
+.P
+The normal callout output, showing the callout number or pattern offset (as
+described above) is suppressed if the \fBcallout_no_where\fP modifier is set.
+.P
+When using the interpretive matching function \fBpcre2_match()\fP without JIT,
+setting the \fBcallout_extra\fP modifier causes additional output from
+\fBpcre2test\fP's callout function to be generated. For the first callout in a
+match attempt at a new starting position in the subject, "New match attempt" is
+output. If there has been a backtrack since the last callout (or start of
+matching if this is the first callout), "Backtrack" is output, followed by "No
+other matching paths" if the backtrack ended the previous match attempt. For
+example:
+.sp
+   re> /(a+)b/auto_callout,no_start_optimize,no_auto_possess
+  data> aac\e=callout_extra
+  New match attempt
+  --->aac
+   +0 ^       (
+   +1 ^       a+
+   +3 ^ ^     )
+   +4 ^ ^     b
+  Backtrack
+  --->aac
+   +3 ^^      )
+   +4 ^^      b
+  Backtrack
+  No other matching paths
+  New match attempt
+  --->aac
+   +0  ^      (
+   +1  ^      a+
+   +3  ^^     )
+   +4  ^^     b
+  Backtrack
+  No other matching paths
+  New match attempt
+  --->aac
+   +0   ^     (
+   +1   ^     a+
+  Backtrack
+  No other matching paths
+  New match attempt
+  --->aac
+   +0    ^    (
+   +1    ^    a+
+  No match
+.sp
+Notice that various optimizations must be turned off if you want all possible
+matching paths to be scanned. If \fBno_start_optimize\fP is not used, there is
+an immediate "no match", without any callouts, because the starting
+optimization fails to find "b" in the subject, which it knows must be present
+for any match. If \fBno_auto_possess\fP is not used, the "a+" item is turned
+into "a++", which reduces the number of backtracks.
+.P
+The \fBcallout_extra\fP modifier has no effect if used with the DFA matching
+function, or with JIT.
+.
+.
+.SS "Return values from callouts"
+.rs
+.sp
+The default return from the callout function is zero, which allows matching to
+continue. The \fBcallout_fail\fP modifier can be given one or two numbers. If
+there is only one number, 1 is returned instead of 0 (causing matching to
+backtrack) when a callout of that number is reached. If two numbers (:)
+are given, 1 is returned when callout  is reached and there have been at
+least  callouts. The \fBcallout_error\fP modifier is similar, except that
+PCRE2_ERROR_CALLOUT is returned, causing the entire matching process to be
+aborted. If both these modifiers are set for the same callout number,
+\fBcallout_error\fP takes precedence. Note that callouts with string arguments
+are always given the number zero.
+.P
+The \fBcallout_data\fP modifier can be given an unsigned or a negative number.
+This is set as the "user data" that is passed to the matching function, and
+passed back when the callout function is invoked. Any value other than zero is
+used as a return from \fBpcre2test\fP's callout function.
+.P
+Inserting callouts can be helpful when using \fBpcre2test\fP to check
+complicated regular expressions. For further information about callouts, see
+the
+.\" HREF
+\fBpcre2callout\fP
+.\"
+documentation.
+.
+.
+.
+.SH "NON-PRINTING CHARACTERS"
+.rs
+.sp
+When \fBpcre2test\fP is outputting text in the compiled version of a pattern,
+bytes other than 32-126 are always treated as non-printing characters and are
+therefore shown as hex escapes.
+.P
+When \fBpcre2test\fP is outputting text that is a matched part of a subject
+string, it behaves in the same way, unless a different locale has been set for
+the pattern (using the \fBlocale\fP modifier). In this case, the
+\fBisprint()\fP function is used to distinguish printing and non-printing
+characters.
+.
+.
+.
+.\" HTML 
+.SH "SAVING AND RESTORING COMPILED PATTERNS"
+.rs
+.sp
+It is possible to save compiled patterns on disc or elsewhere, and reload them
+later, subject to a number of restrictions. JIT data cannot be saved. The host
+on which the patterns are reloaded must be running the same version of PCRE2,
+with the same code unit width, and must also have the same endianness, pointer
+width and PCRE2_SIZE type. Before compiled patterns can be saved they must be
+serialized, that is, converted to a stream of bytes. A single byte stream may
+contain any number of compiled patterns, but they must all use the same
+character tables. A single copy of the tables is included in the byte stream
+(its size is 1088 bytes).
+.P
+The functions whose names begin with \fBpcre2_serialize_\fP are used
+for serializing and de-serializing. They are described in the
+.\" HREF
+\fBpcre2serialize\fP
+.\"
+documentation. In this section we describe the features of \fBpcre2test\fP that
+can be used to test these functions.
+.P
+Note that "serialization" in PCRE2 does not convert compiled patterns to an
+abstract format like Java or .NET. It just makes a reloadable byte code stream.
+Hence the restrictions on reloading mentioned above.
+.P
+In \fBpcre2test\fP, when a pattern with \fBpush\fP modifier is successfully
+compiled, it is pushed onto a stack of compiled patterns, and \fBpcre2test\fP
+expects the next line to contain a new pattern (or command) instead of a
+subject line. By contrast, the \fBpushcopy\fP modifier causes a copy of the
+compiled pattern to be stacked, leaving the original available for immediate
+matching. By using \fBpush\fP and/or \fBpushcopy\fP, a number of patterns can
+be compiled and retained. These modifiers are incompatible with \fBposix\fP,
+and control modifiers that act at match time are ignored (with a message) for
+the stacked patterns. The \fBjitverify\fP modifier applies only at compile
+time.
+.P
+The command
+.sp
+  #save 
+.sp
+causes all the stacked patterns to be serialized and the result written to the
+named file. Afterwards, all the stacked patterns are freed. The command
+.sp
+  #load 
+.sp
+reads the data in the file, and then arranges for it to be de-serialized, with
+the resulting compiled patterns added to the pattern stack. The pattern on the
+top of the stack can be retrieved by the #pop command, which must be followed
+by lines of subjects that are to be matched with the pattern, terminated as
+usual by an empty line or end of file. This command may be followed by a
+modifier list containing only
+.\" HTML 
+.\" 
+control modifiers
+.\"
+that act after a pattern has been compiled. In particular, \fBhex\fP,
+\fBposix\fP, \fBposix_nosub\fP, \fBpush\fP, and \fBpushcopy\fP are not allowed,
+nor are any
+.\" HTML 
+.\" 
+option-setting modifiers.
+.\"
+The JIT modifiers are, however permitted. Here is an example that saves and
+reloads two patterns.
+.sp
+  /abc/push
+  /xyz/push
+  #save tempfile
+  #load tempfile
+  #pop info
+  xyz
+.sp
+  #pop jit,bincode
+  abc
+.sp
+If \fBjitverify\fP is used with #pop, it does not automatically imply
+\fBjit\fP, which is different behaviour from when it is used on a pattern.
+.P
+The #popcopy command is analogous to the \fBpushcopy\fP modifier in that it
+makes current a copy of the topmost stack pattern, leaving the original still
+on the stack.

+
+
+NAME
+       pcre2test - a program for testing Perl-compatible regular expressions.
+
+
+SYNOPSIS
+
+       pcre2test [options] [input file [output file]]
+
+       pcre2test is a test program for the PCRE2 regular expression libraries,
+       but  it  can  also  be used for experimenting with regular expressions.
+       This document describes the features of the test program;  for  details
+       of  the regular expressions themselves, see the pcre2pattern documenta-
+       tion. For details of the PCRE2 library function  calls  and  their  op-
+       tions, see the pcre2api documentation.
+
+       The  input  for  pcre2test is a sequence of regular expression patterns
+       and subject strings to be matched. There are  also  command  lines  for
+       setting defaults and controlling some special actions. The output shows
+       the  result  of  each  match attempt. Modifiers on external or internal
+       command lines, the patterns, and the subject lines specify PCRE2  func-
+       tion  options, control how the subject is processed, and what output is
+       produced.
+
+       There are many obscure modifiers, some of which  are  specifically  de-
+       signed  for use in conjunction with the test script and data files that
+       are distributed as part of PCRE2.  All  the  modifiers  are  documented
+       here, some without much justification, but many of them are unlikely to
+       be of use except when testing the libraries.
+
+
+PCRE2's 8-BIT, 16-BIT AND 32-BIT LIBRARIES
+
+       Different versions of the PCRE2 library can be built to support charac-
+       ter  strings  that  are encoded in 8-bit, 16-bit, or 32-bit code units.
+       One, two, or all three of these libraries  may  be  simultaneously  in-
+       stalled.  The  pcre2test program can be used to test all the libraries.
+       However, its own input and output are  always  in  8-bit  format.  When
+       testing  the  16-bit  or 32-bit libraries, patterns and subject strings
+       are converted to 16-bit or 32-bit format before being passed to the li-
+       brary functions. Results are converted back to  8-bit  code  units  for
+       output.
+
+       In the rest of this document, the names of library functions and struc-
+       tures  are given in generic form, for example, pcre2_compile(). The ac-
+       tual names used in the libraries have a suffix _8, _16, or _32, as  ap-
+       propriate.
+
+
+INPUT ENCODING
+
+       Input  to  pcre2test is processed line by line, either by calling the C
+       library's fgets() function, or via the libreadline or libedit  library.
+       In  some Windows environments character 26 (hex 1A) causes an immediate
+       end of file, and no further data is read, so this character  should  be
+       avoided unless you really want that action.
+
+       The  input is processed using C's string functions, so must not contain
+       binary zeros, even though in Unix-like environments, fgets() treats any
+       bytes other than newline as data characters. An error is generated if a
+       binary zero is encountered. By default subject lines are processed  for
+       backslash escapes, which makes it possible to include any data value in
+       strings  that  are  passed  to  the library for matching. For patterns,
+       there is a facility for specifying some or all of the 8-bit input char-
+       acters as hexadecimal pairs, which makes it possible to include  binary
+       zeros.
+
+   Input for the 16-bit and 32-bit libraries
+
+       When testing the 16-bit or 32-bit libraries, there is a need to be able
+       to  generate character code points greater than 255 in the strings that
+       are passed to the library. For subject lines, backslash escapes can  be
+       used.  In addition, when the utf modifier (see "Setting compilation op-
+       tions" below) is set, the pattern and any following subject  lines  are
+       interpreted  as UTF-8 strings and translated to UTF-16 or UTF-32 as ap-
+       propriate.
+
+       For non-UTF testing of wide characters, the utf8_input modifier can  be
+       used.  This  is  mutually  exclusive  with  utf, and is allowed only in
+       16-bit or 32-bit mode. It causes  the  pattern  and  following  subject
+       lines  to be treated as UTF-8 according to the original definition (RFC
+       2279), which allows for character values up to 0x7fffffff. Each charac-
+       ter is placed in one 16-bit or 32-bit code unit (in  the  16-bit  case,
+       values greater than 0xffff cause an error to occur).
+
+       UTF-8  (in  its  original definition) is not capable of encoding values
+       greater than 0x7fffffff, but such values can be handled by  the  32-bit
+       library. When testing this library in non-UTF mode with utf8_input set,
+       if any character is preceded by the byte 0xff (which is an invalid byte
+       in  UTF-8)  0x80000000  is  added to the character's value. This is the
+       only way of passing such code points in a pattern string.  For  subject
+       strings, using an escape sequence is preferable.

+
+COMMAND LINE OPTIONS
+
+       -8        If the 8-bit library has been built, this option causes it to
+                 be  used  (this is the default). If the 8-bit library has not
+                 been built, this option causes an error.
+
+       -16       If the 16-bit library has been built, this option  causes  it
+                 to  be used. If the 8-bit library has not been built, this is
+                 the default. If the 16-bit library has not been  built,  this
+                 option causes an error.
+
+       -32       If  the  32-bit library has been built, this option causes it
+                 to be used. If no other library has been built, this  is  the
+                 default.  If  the 32-bit library has not been built, this op-
+                 tion causes an error.
+
+       -ac       Behave as if each pattern has the auto_callout modifier, that
+                 is, insert automatic callouts into every pattern that is com-
+                 piled.
+
+       -AC       As for -ac, but in addition behave as if  each  subject  line
+                 has  the callout_extra modifier, that is, show additional in-
+                 formation from callouts.
+
+       -b        Behave as if each pattern has the fullbincode  modifier;  the
+                 full internal binary form of the pattern is output after com-
+                 pilation.
+
+       -C        Output  the  version  number  of  the  PCRE2 library, and all
+                 available information about the optional  features  that  are
+                 included,  and  then  exit with zero exit code. All other op-
+                 tions are ignored. If both -C and -LM are present,  whichever
+                 is first is recognized.
+
+       -C option Output  information  about a specific build-time option, then
+                 exit. This functionality is intended for use in scripts  such
+                 as  RunTest.  The  following options output the value and set
+                 the exit code as indicated:
+

+                                exit code is always 0
+
+                 The following options output 1 for true or 0 for  false,  and
+                 set the exit code to the same value:
+
+                   backslash-C  \C is supported (not locked out)

+
+       -d        Behave as if each pattern has the debug modifier; the  inter-
+                 nal form and information about the compiled pattern is output
+                 after compilation; -d is equivalent to -b -i.
+
+       -dfa      Behave as if each subject line has the dfa modifier; matching
+                 is  done  using the pcre2_dfa_match() function instead of the
+                 default pcre2_match().

+                 Call pcre2_get_error_message() for each of the error  numbers
+                 in  the  comma-separated list, display the resulting messages
+                 on the standard output, then exit with zero  exit  code.  The
+                 numbers  may  be  positive or negative. This is a convenience
+                 facility for PCRE2 maintainers.
+
+       -help     Output a brief summary these options and then exit.
+
+       -i        Behave as if each pattern has the info modifier;  information
+                 about the compiled pattern is given after compilation.
+
+       -jit      Behave  as  if  each pattern line has the jit modifier; after
+                 successful compilation, each pattern is passed to  the  just-
+                 in-time compiler, if available.
+
+       -jitfast  Behave  as if each pattern line has the jitfast modifier; af-
+                 ter successful compilation, each pattern  is  passed  to  the
+                 just-in-time compiler, if available, and each subject line is
+                 passed directly to the JIT matcher via its "fast path".
+
+       -jitverify
+                 Behave  as  if  each pattern line has the jitverify modifier;
+                 after successful compilation, each pattern is passed  to  the
+                 just-in-time  compiler,  if available, and the use of JIT for
+                 matching is verified.
+
+       -LM       List modifiers: write a list of available pattern and subject
+                 modifiers to the standard output, then exit  with  zero  exit
+                 code.  All other options are ignored.  If both -C and any -Lx
+                 options are present, whichever is first is recognized.
+
+       -LP       List properties: write a list of recognized  Unicode  proper-
+                 ties  to  the standard output, then exit with zero exit code.
+                 All other options are ignored. If both -C and any -Lx options
+                 are present, whichever is first is recognized.
+
+       -LS       List scripts: write a list of recognized Unicode script names
+                 to the standard output, then exit with zero  exit  code.  All
+                 other options are ignored. If both -C and any -Lx options are
+                 present, whichever is first is recognized.
+
+       -pattern modifier-list
+                 Behave as if each pattern line contains the given modifiers.
+
+       -q        Do not output the version number of pcre2test at the start of
+                 execution.
+
+       -S size   On  Unix-like  systems, set the size of the run-time stack to
+                 size mebibytes (units of 1024*1024 bytes).
+
+       -subject modifier-list
+                 Behave as if each subject line contains the given modifiers.
+
+       -t        Run each compile and match many times with a timer, and  out-
+                 put  the  resulting  times  per compile or match. When JIT is
+                 used, separate times are given for the  initial  compile  and
+                 the  JIT  compile.  You  can control the number of iterations
+                 that are used for timing by following -t with a number (as  a
+                 separate  item  on  the command line). For example, "-t 1000"
+                 iterates 1000 times. The default is to iterate 500,000 times.
+
+       -tm       This is like -t except that it times only the matching phase,
+                 not the compile phase.
+
+       -T -TM    These behave like -t and -tm, but in addition, at the end  of
+                 a  run, the total times for all compiles and matches are out-
+                 put.
+
+       -version  Output the PCRE2 version number and then exit.

+
+DESCRIPTION
+
+       If pcre2test is given two filename arguments, it reads from  the  first
+       and writes to the second. If the first name is "-", input is taken from
+       the  standard  input. If pcre2test is given only one argument, it reads
+       from that file and writes to stdout. Otherwise, it reads from stdin and
+       writes to stdout.
+
+       When pcre2test is built, a configuration option  can  specify  that  it
+       should  be linked with the libreadline or libedit library. When this is
+       done, if the input is from a terminal, it is read using the  readline()
+       function. This provides line-editing and history facilities. The output
+       from the -help option states whether or not readline() will be used.
+
+       The  program  handles  any number of tests, each of which consists of a
+       set of input lines. Each set starts with a regular expression  pattern,
+       followed by any number of subject lines to be matched against that pat-
+       tern. In between sets of test data, command lines that begin with # may
+       appear. This file format, with some restrictions, can also be processed
+       by  the perltest.sh script that is distributed with PCRE2 as a means of
+       checking that the behaviour of PCRE2 and Perl is the same. For a speci-
+       fication of perltest.sh, see the comments near its beginning. See  also
+       the #perltest command below.
+
+       When the input is a terminal, pcre2test prompts for each line of input,
+       using  "re>"  to prompt for regular expression patterns, and "data>" to
+       prompt for subject lines. Command lines starting with # can be  entered
+       only in response to the "re>" prompt.
+
+       Each  subject line is matched separately and independently. If you want
+       to do multi-line matches, you have to use the \n escape sequence (or \r
+       or \r\n, etc., depending on the newline setting) in a  single  line  of
+       input  to encode the newline sequences. There is no limit on the length
+       of subject lines; the input buffer is automatically extended if  it  is
+       too  small.  There  are  replication features that makes it possible to
+       generate long repetitive pattern or subject  lines  without  having  to
+       supply them explicitly.
+
+       An  empty  line  or  the end of the file signals the end of the subject
+       lines for a test, at which point a new pattern or command line  is  ex-
+       pected if there is still input to be read.
+
+
+COMMAND LINES
+
+       In  between sets of test data, a line that begins with # is interpreted
+       as a command line. If the first character is followed by white space or
+       an exclamation mark, the line is treated as  a  comment,  and  ignored.
+       Otherwise, the following commands are recognized:
+
+         #forbid_utf
+
+       Subsequent   patterns   automatically   have  the  PCRE2_NEVER_UTF  and
+       PCRE2_NEVER_UCP options set, which locks out the use of  the  PCRE2_UTF
+       and  PCRE2_UCP options and the use of (*UTF) and (*UCP) at the start of
+       patterns. This command also forces an error  if  a  subsequent  pattern
+       contains  any  occurrences  of \P, \p, or \X, which are still supported
+       when PCRE2_UTF is not set, but which require Unicode  property  support
+       to be included in the library.
+
+       This  is  a trigger guard that is used in test files to ensure that UTF
+       or Unicode property tests are not accidentally added to files that  are
+       used  when  Unicode  support  is  not  included in the library. Setting
+       PCRE2_NEVER_UTF and PCRE2_NEVER_UCP as a default can also  be  obtained
+       by  the  use  of #pattern; the difference is that #forbid_utf cannot be
+       unset, and the automatic options are not displayed in pattern  informa-
+       tion, to avoid cluttering up test output.
+
+         #load 
+
+       This command is used to load a set of precompiled patterns from a file,
+       as  described  in  the  section entitled "Saving and restoring compiled
+       patterns" below.
+
+         #loadtables 
+
+       This command is used to load a set of binary character tables that  can
+       be  accessed  by  the tables=3 qualifier. Such tables can be created by
+       the pcre2_dftables program with the -b option.
+
+         #newline_default []
+
+       When PCRE2 is built, a default newline  convention  can  be  specified.
+       This  determines which characters and/or character pairs are recognized
+       as indicating a newline in a pattern or subject string. The default can
+       be overridden when a pattern is compiled. The standard test files  con-
+       tain  tests  of  various  newline  conventions, but the majority of the
+       tests expect a single linefeed to be recognized as  a  newline  by  de-
+       fault.  Without  special action the tests would fail when PCRE2 is com-
+       piled with either CR or CRLF as the default newline.
+
+       The #newline_default command specifies a list of newline types that are
+       acceptable as the default. The types must be one of CR, LF, CRLF,  ANY-
+       CRLF, ANY, or NUL (in upper or lower case), for example:
+
+         #newline_default LF Any anyCRLF
+
+       If the default newline is in the list, this command has no effect. Oth-
+       erwise,  except  when  testing  the  POSIX API, a newline modifier that
+       specifies the first newline convention in the list (LF in the above ex-
+       ample) is added to any pattern that does not  already  have  a  newline
+       modifier. If the newline list is empty, the feature is turned off. This
+       command is present in a number of the standard test input files.
+
+       When  the POSIX API is being tested there is no way to override the de-
+       fault newline convention, though it is possible to set the newline con-
+       vention from within the pattern. A warning is given  if  the  posix  or
+       posix_nosub  modifier is used when #newline_default would set a default
+       for the non-POSIX API.
+
+         #pattern 
+
+       This command sets a default modifier list that applies  to  all  subse-
+       quent patterns. Modifiers on a pattern can change these settings.
+
+         #perltest
+
+       This  line  is  used  in test files that can also be processed by perl-
+       test.sh to confirm that Perl gives the same results  as  PCRE2.  Subse-
+       quent  tests are checked for the use of pcre2test features that are in-
+       compatible with the perltest.sh script.
+
+       Patterns must use '/' as their delimiter, and  only  certain  modifiers
+       are  supported. Comment lines, #pattern commands, and #subject commands
+       that set or unset "mark" are recognized and acted  on.  The  #perltest,
+       #forbid_utf,  and  #newline_default  commands,  which are needed in the
+       relevant pcre2test files, are silently ignored. All other command lines
+       are ignored, but give a warning message. The  #perltest  command  helps
+       detect  tests  that  are  accidentally put in the wrong file or use the
+       wrong delimiter. For more details of the  perltest.sh  script  see  the
+       comments it contains.
+
+         #pop []
+         #popcopy []
+
+       These  commands  are used to manipulate the stack of compiled patterns,
+       as described in the section entitled  "Saving  and  restoring  compiled
+       patterns" below.
+
+         #save 
+
+       This  command  is used to save a set of compiled patterns to a file, as
+       described in the section entitled "Saving and restoring  compiled  pat-
+       terns" below.
+
+         #subject 
+
+       This  command  sets  a default modifier list that applies to all subse-
+       quent subject lines. Modifiers on a subject line can change these  set-

+MODIFIER SYNTAX
+
+       Modifier lists are used with both pattern and subject lines. Items in a
+       list are separated by commas followed by optional white space. Trailing
+       whitespace  in  a modifier list is ignored. Some modifiers may be given
+       for both patterns and subject lines, whereas others are valid only  for
+       one  or  the  other.  Each  modifier  has a long name, for example "an-
+       chored", and some of them must be followed by  an  equals  sign  and  a
+       value,  for  example,  "offset=12". Values cannot contain comma charac-
+       ters, but may contain spaces. Modifiers that do not take values may  be
+       preceded by a minus sign to turn off a previous setting.
+
+       A few of the more common modifiers can also be specified as single let-
+       ters,  for  example "i" for "caseless". In documentation, following the
+       Perl convention, these are written with a slash ("the /i modifier") for
+       clarity. Abbreviated modifiers must all be concatenated  in  the  first
+       item  of a modifier list. If the first item is not recognized as a long
+       modifier name, it is interpreted as a sequence of these  abbreviations.
+       For example:
+
+         /abc/ig,newline=cr,jit=3
+
+       This  is  a pattern line whose modifier list starts with two one-letter
+       modifiers (/i and /g). The lower-case  abbreviated  modifiers  are  the
+       same as used in Perl.
+
+
+PATTERN SYNTAX
+
+       A  pattern line must start with one of the following characters (common
+       symbols, excluding pattern meta-characters):
+
+         / ! " ' ` - = _ : ; , % & @ ~
+
+       This is interpreted as the pattern's delimiter.  A  regular  expression
+       may  be  continued  over several input lines, in which case the newline
+       characters are included within it. It is possible to include the delim-
+       iter as a literal within the pattern by escaping it with  a  backslash,
+       for example
+
+         /abc\/def/
+
+       If  you do this, the escape and the delimiter form part of the pattern,
+       but since the delimiters are all non-alphanumeric, the inclusion of the
+       backslash does not affect the pattern's interpretation. Note,  however,
+       that this trick does not work within \Q...\E literal bracketing because
+       the backslash will itself be interpreted as a literal. If the terminat-
+       ing delimiter is immediately followed by a backslash, for example,
+
+         /abc/\
+
+       a backslash is added to the end of the pattern. This is done to provide
+       a  way of testing the error condition that arises if a pattern finishes
+       with a backslash, because
+
+         /abc\/
+
+       is interpreted as the first line of a pattern that starts with  "abc/",
+       causing  pcre2test to read the next line as a continuation of the regu-
+       lar expression.
+
+       A pattern can be followed by a modifier list (details below).
+
+
+SUBJECT LINE SYNTAX
+
+       Before each subject line is passed to pcre2_match(), pcre2_dfa_match(),
+       or pcre2_jit_match(), leading and trailing white space is removed,  and
+       the  line  is scanned for backslash escapes, unless the subject_literal
+       modifier was set for the pattern. The following provide a means of  en-
+       coding non-printing characters in a visible way:
+
+         \a         alarm (BEL, \x07)
+         \b         backspace (\x08)
+         \e         escape (\x27)
+         \f         form feed (\x0c)
+         \n         newline (\x0a)
+         \r         carriage return (\x0d)
+         \t         tab (\x09)
+         \v         vertical tab (\x0b)
+         \nnn       octal character (up to 3 octal digits); always
+                      a byte unless > 255 in UTF-8 or 16-bit or 32-bit mode
+         \o{dd...}  octal character (any number of octal digits}
+         \xhh       hexadecimal byte (up to 2 hex digits)
+         \x{hh...}  hexadecimal character (any number of hex digits)
+
+       The use of \x{hh...} is not dependent on the use of the utf modifier on
+       the  pattern. It is recognized always. There may be any number of hexa-
+       decimal digits inside the braces; invalid  values  provoke  error  mes-
+       sages.
+
+       Note  that  \xhh  specifies one byte rather than one character in UTF-8
+       mode; this makes it possible to construct invalid UTF-8  sequences  for
+       testing  purposes.  On the other hand, \x{hh} is interpreted as a UTF-8
+       character in UTF-8 mode, generating more than one byte if the value  is
+       greater  than  127.   When testing the 8-bit library not in UTF-8 mode,
+       \x{hh} generates one byte for values less than 256, and causes an error
+       for greater values.
+
+       In UTF-16 mode, all 4-digit \x{hhhh} values are accepted. This makes it
+       possible to construct invalid UTF-16 sequences for testing purposes.
+
+       In UTF-32 mode, all 4- to 8-digit \x{...}  values  are  accepted.  This
+       makes  it  possible  to  construct invalid UTF-32 sequences for testing
+       purposes.
+
+       There is a special backslash sequence that specifies replication of one
+       or more characters:
+
+         \[]{}
+
+       This makes it possible to test long strings without having  to  provide
+       them as part of the file. For example:
+
+         \[abc]{4}
+
+       is  converted to "abcabcabcabc". This feature does not support nesting.
+       To include a closing square bracket in the characters, code it as \x5D.
+
+       A backslash followed by an equals sign marks the  end  of  the  subject
+       string and the start of a modifier list. For example:
+
+         abc\=notbol,notempty
+
+       If  the  subject  string is empty and \= is followed by whitespace, the
+       line is treated as a comment line, and is not used  for  matching.  For
+       example:
+
+         \= This is a comment.
+         abc\= This is an invalid modifier list.
+
+       A  backslash  followed by any other non-alphanumeric character just es-
+       capes that character. A backslash followed by anything else  causes  an
+       error.  However,  if the very last character in the line is a backslash
+       (and there is no modifier list), it is ignored. This  gives  a  way  of
+       passing  an  empty line as data, since a real empty line terminates the
+       data input.
+
+       If the subject_literal modifier is set for a pattern, all subject lines
+       that follow are treated as literals, with no special treatment of back-
+       slashes.  No replication is possible, and any subject modifiers must be
+       set as defaults by a #subject command.
+
+
+PATTERN MODIFIERS
+
+       There are several types of modifier that can appear in  pattern  lines.
+       Except where noted below, they may also be used in #pattern commands. A
+       pattern's  modifier  list can add to or override default modifiers that
+       were set by a previous #pattern command.
+
+   Setting compilation options
+
+       The following modifiers set options for pcre2_compile(). Most  of  them
+       set  bits  in  the  options  argument of that function, but those whose
+       names start with PCRE2_EXTRA are additional options that are set in the
+       compile context.  Some of these options  have  single-letter  abbrevia-
+       tions.  There  is  special  handling  for /x: if a second x is present,
+       PCRE2_EXTENDED is converted into  PCRE2_EXTENDED_MORE  as  in  Perl.  A
+       third appearance adds PCRE2_EXTENDED as well, though this makes no dif-
+       ference to the way pcre2_compile() behaves. See pcre2api for a descrip-
+       tion of the effects of these options.

+             utf                       set PCRE2_UTF
+
+       As well as turning on the PCRE2_UTF option, the utf modifier causes all
+       non-printing  characters  in  output  strings  to  be printed using the
+       \x{hh...} notation. Otherwise, those less than 0x100 are output in  hex
+       without  the  curly brackets. Setting utf in 16-bit or 32-bit mode also
+       causes pattern and subject  strings  to  be  translated  to  UTF-16  or
+       UTF-32, respectively, before being passed to library functions.
+
+   Setting compilation controls
+
+       The  following  modifiers affect the compilation process or request in-
+       formation about the pattern. There are single-letter abbreviations  for
+       some that are heavily used in the test files.

+             utf8_input                treat input as UTF-8
+
+       The effects of these modifiers are described in the following sections.
+
+   Newline and \R handling
+
+       The  bsr modifier specifies what \R in a pattern should match. If it is
+       set to "anycrlf", \R matches CR, LF, or CRLF only.  If  it  is  set  to
+       "unicode",  \R matches any Unicode newline sequence. The default can be
+       specified when PCRE2 is built; if it is not, the default is set to Uni-
+       code.
+
+       The newline modifier specifies which characters are to  be  interpreted
+       as newlines, both in the pattern and in subject lines. The type must be
+       one of CR, LF, CRLF, ANYCRLF, ANY, or NUL (in upper or lower case).
+
+   Information about a pattern
+
+       The  debug modifier is a shorthand for info,fullbincode, requesting all
+       available information.
+
+       The bincode modifier causes a representation of the compiled code to be
+       output after compilation. This information does not contain length  and
+       offset values, which ensures that the same output is generated for dif-
+       ferent  internal  link  sizes  and different code unit widths. By using
+       bincode, the same regression tests can be used  in  different  environ-
+       ments.
+
+       The  fullbincode  modifier, by contrast, does include length and offset
+       values. This is used in a few special tests that run only for  specific
+       code unit widths and link sizes, and is also useful for one-off tests.
+
+       The  info  modifier  requests  information  about  the compiled pattern
+       (whether it is anchored, has a fixed first character, and so  on).  The
+       information  is  obtained  from the pcre2_pattern_info() function. Here
+       are some typical examples:
+
+           re> /(?i)(^a|^b)/m,info
+         Capture group count = 1
+         Compile options: multiline
+         Overall options: caseless multiline
+         First code unit at start or follows newline
+         Subject length lower bound = 1
+
+           re> /(?i)abc/info
+         Capture group count = 0
+         Compile options: 
+         Overall options: caseless
+         First code unit = 'a' (caseless)
+         Last code unit = 'c' (caseless)
+         Subject length lower bound = 3
+
+       "Compile options" are those specified by modifiers;  "overall  options"
+       have  added options that are taken or deduced from the pattern. If both
+       sets of options are the same, just a single "options" line  is  output;
+       if  there  are  no  options,  the line is omitted. "First code unit" is
+       where any match must start; if there is more than one they  are  listed
+       as  "starting  code  units".  "Last code unit" is the last literal code
+       unit that must be present in any match. This  is  not  necessarily  the
+       last  character.  These lines are omitted if no starting or ending code
+       units  are  recorded.  The  subject  length  line   is   omitted   when
+       no_start_optimize  is  set because the minimum length is not calculated
+       when it can never be used.
+
+       The framesize modifier shows the size, in bytes, of each storage  frame
+       used  by  pcre2_match()  for handling backtracking. The size depends on
+       the number of capturing parentheses in the pattern. A vector  of  these
+       frames  is  used  at  matching time; its overall size is shown when the
+       heaframes_size subject modifier is set.
+
+       The callout_info modifier requests information about all  the  callouts
+       in the pattern. A list of them is output at the end of any other infor-
+       mation that is requested. For each callout, either its number or string
+       is given, followed by the item that follows it in the pattern.
+
+   Passing a NULL context
+
+       Normally,  pcre2test  passes a context block to pcre2_compile(). If the
+       null_context modifier is set, however, NULL  is  passed.  This  is  for
+       testing  that  pcre2_compile()  behaves correctly in this case (it uses
+       default values).
+
+   Passing a NULL pattern
+
+       The null_pattern modifier is for testing the  behaviour  of  pcre2_com-
+       pile()  when  the  pattern argument is NULL. The length value passed is
+       the default PCRE2_ZERO_TERMINATED unless use_length is set.  Any length
+       other than zero causes an error.
+
+   Specifying pattern characters in hexadecimal
+
+       The hex modifier specifies that the characters of the  pattern,  except
+       for  substrings  enclosed  in single or double quotes, are to be inter-
+       preted as pairs of hexadecimal digits. This feature is  provided  as  a
+       way of creating patterns that contain binary zeros and other non-print-
+       ing  characters.  White space is permitted between pairs of digits. For
+       example, this pattern contains three characters:
+
+         /ab 32 59/hex
+
+       Parts of such a pattern are taken literally  if  quoted.  This  pattern
+       contains  nine characters, only two of which are specified in hexadeci-
+       mal:
+
+         /ab "literal" 32/hex
+
+       Either single or double quotes may be used. There is no way of  includ-
+       ing  the delimiter within a substring. The hex and expand modifiers are
+       mutually exclusive.
+
+   Specifying the pattern's length
+
+       By default, patterns are passed to the compiling functions as zero-ter-
+       minated strings but can be passed by length instead of being  zero-ter-
+       minated.  The use_length modifier causes this to happen. Using a length
+       happens automatically (whether or not use_length is set)  when  hex  is
+       set,  because  patterns specified in hexadecimal may contain binary ze-
+       ros.
+
+       If hex or use_length is used with the POSIX wrapper API (see "Using the
+       POSIX wrapper API" below), the REG_PEND extension is used to  pass  the
+       pattern's length.
+
+   Specifying a maximum for variable lookbehinds
+
+       Variable  lookbehind  assertions  are  supported only if, for each one,
+       there is a maximum length (in characters) that it can match. There is a
+       limit on this, whose default can be set at build time, with an ultimate
+       default   of   255.   The   max_varlookbehind   modifier    uses    the
+       pcre2_set_max_varlookbehind() function to change the limit. Lookbehinds
+       whose  branches  each match a fixed length are limited to 65535 charac-
+       ters per branch.
+
+   Specifying wide characters in 16-bit and 32-bit modes
+
+       In 16-bit and 32-bit modes, all input is automatically treated as UTF-8
+       and translated to UTF-16 or UTF-32 when the utf modifier  is  set.  For
+       testing the 16-bit and 32-bit libraries in non-UTF mode, the utf8_input
+       modifier  can  be  used. It is mutually exclusive with utf. Input lines
+       are interpreted as UTF-8 as a means of specifying wide characters. More
+       details are given in "Input encoding" above.
+
+   Generating long repetitive patterns
+
+       Some tests use long patterns that are very repetitive. Instead of  cre-
+       ating  a very long input line for such a pattern, you can use a special
+       repetition feature, similar to the  one  described  for  subject  lines
+       above.  If  the  expand  modifier is present on a pattern, parts of the
+       pattern that have the form
+
+         \[]{}
+
+       are expanded before the pattern is passed to pcre2_compile(). For exam-
+       ple, \[AB]{6000} is expanded to "ABAB..." 6000 times. This construction
+       cannot be nested. An initial "\[" sequence is recognized only  if  "]{"
+       followed  by  decimal  digits and "}" is found later in the pattern. If
+       not, the characters remain in the pattern unaltered. The expand and hex
+       modifiers are mutually exclusive.
+
+       If part of an expanded pattern looks like an expansion, but  is  really
+       part of the actual pattern, unwanted expansion can be avoided by giving
+       two values in the quantifier. For example, \[AB]{6000,6000} is not rec-
+       ognized as an expansion item.
+
+       If  the  info modifier is set on an expanded pattern, the result of the
+       expansion is included in the information that is output.
+
+   JIT compilation
+
+       Just-in-time (JIT) compiling is a  heavyweight  optimization  that  can
+       greatly  speed  up pattern matching. See the pcre2jit documentation for
+       details. JIT compiling happens, optionally, after a  pattern  has  been
+       successfully  compiled into an internal form. The JIT compiler converts
+       this to optimized machine code. It needs to know whether the match-time
+       options PCRE2_PARTIAL_HARD and PCRE2_PARTIAL_SOFT are going to be used,
+       because different code is generated for the different  cases.  See  the
+       partial  modifier in "Subject Modifiers" below for details of how these
+       options are specified for each match attempt.
+
+       JIT compilation is requested by the jit pattern modifier, which may op-
+       tionally be followed by an equals sign and a number in the range  0  to
+       7.   The  three bits that make up the number specify which of the three
+       JIT operating modes are to be compiled:
+
+         1  compile JIT code for non-partial matching
+         2  compile JIT code for soft partial matching
+         4  compile JIT code for hard partial matching
+
+       The possible values for the jit modifier are therefore:
+
+         0  disable JIT
+         1  normal matching only
+         2  soft partial matching only
+         3  normal and soft partial matching
+         4  hard partial matching only
+         6  soft and hard partial matching only
+         7  all three modes
+
+       If no number is given, 7 is  assumed.  The  phrase  "partial  matching"
+       means a call to pcre2_match() with either the PCRE2_PARTIAL_SOFT or the
+       PCRE2_PARTIAL_HARD  option set. Note that such a call may return a com-
+       plete match; the options enable the possibility of a partial match, but
+       do not require it. Note also that if you request JIT  compilation  only
+       for  partial  matching  (for example, jit=2) but do not set the partial
+       modifier on a subject line, that match will not use  JIT  code  because
+       none was compiled for non-partial matching.
+
+       If  JIT compilation is successful, the compiled JIT code will automati-
+       cally be used when an appropriate type of match is run, except when in-
+       compatible run-time options are specified. For more  details,  see  the
+       pcre2jit  documentation. See also the jitstack modifier below for a way
+       of setting the size of the JIT stack.
+
+       If the jitfast modifier is specified, matching is done  using  the  JIT
+       "fast  path" interface, pcre2_jit_match(), which skips some of the san-
+       ity checks that are done by pcre2_match(), and of course does not  work
+       when  JIT  is not supported. If jitfast is specified without jit, jit=7
+       is assumed.
+
+       If the jitverify modifier is specified, information about the  compiled
+       pattern  shows  whether  JIT  compilation was or was not successful. If
+       jitverify is specified without jit, jit=7 is assumed. If  JIT  compila-
+       tion  is successful when jitverify is set, the text "(JIT)" is added to
+       the first output line after a match or non match when JIT-compiled code
+       was actually used in the match.
+
+   Setting a locale
+
+       The locale modifier must specify the name of a locale, for example:
+
+         /pattern/locale=fr_FR
+
+       The given locale is set, pcre2_maketables() is called to build a set of
+       character tables for the locale, and this is then passed to  pcre2_com-
+       pile()  when compiling the regular expression. The same tables are used
+       when matching the following subject lines. The locale modifier  applies
+       only to the pattern on which it appears, but can be given in a #pattern
+       command  if a default is needed. Setting a locale and alternate charac-
+       ter tables are mutually exclusive.
+
+   Showing pattern memory
+
+       The memory modifier causes the size in bytes of the memory used to hold
+       the compiled pattern to be output. This does not include  the  size  of
+       the  pcre2_code block; it is just the actual compiled data. If the pat-
+       tern is subsequently passed to the JIT compiler, the size  of  the  JIT
+       compiled code is also output. Here is an example:
+
+           re> /a(b)c/jit,memory
+         Memory allocation (code space): 21
+         Memory allocation (JIT code): 1910
+
+
+   Limiting nested parentheses
+
+       The  parens_nest_limit  modifier  sets  a  limit on the depth of nested
+       parentheses in a pattern. Breaching the limit causes a compilation  er-
+       ror.   The  default  for  the  library  is set when PCRE2 is built, but
+       pcre2test sets its own default of 220, which is  required  for  running
+       the standard test suite.
+
+   Limiting the pattern length
+
+       The  max_pattern_length  modifier  sets  a limit, in code units, to the
+       length of pattern that pcre2_compile() will accept. Breaching the limit
+       causes a compilation  error.  The  default  is  the  largest  number  a
+       PCRE2_SIZE variable can hold (essentially unlimited).
+
+   Limiting the size of a compiled pattern
+
+       The max_pattern_compiled_length modifier sets a limit, in bytes, to the
+       amount of memory used by a compiled pattern. Breaching the limit causes
+       a  compilation  error.  The  default is the largest number a PCRE2_SIZE
+       variable can hold (essentially unlimited).
+
+   Using the POSIX wrapper API
+
+       The posix and posix_nosub modifiers cause pcre2test to call  PCRE2  via
+       the  POSIX  wrapper API rather than its native API. When posix_nosub is
+       used, the POSIX option REG_NOSUB is  passed  to  regcomp().  The  POSIX
+       wrapper  supports  only  the 8-bit library. Note that it does not imply
+       POSIX matching semantics; for more detail see the pcre2posix documenta-
+       tion. The following pattern modifiers set  options  for  the  regcomp()
+       function:
+
+         caseless           REG_ICASE
+         multiline          REG_NEWLINE
+         dotall             REG_DOTALL     )
+         ungreedy           REG_UNGREEDY   ) These options are not part of
+         ucp                REG_UCP        )   the POSIX standard
+         utf                REG_UTF8       )
+
+       The  regerror_buffsize  modifier  specifies a size for the error buffer
+       that is passed to regerror() in the event of a compilation  error.  For
+       example:
+
+         /abc/posix,regerror_buffsize=20
+
+       This  provides  a means of testing the behaviour of regerror() when the
+       buffer is too small for the error message. If  this  modifier  has  not
+       been set, a large buffer is used.
+
+       The  aftertext and allaftertext subject modifiers work as described be-
+       low. All other modifiers are either ignored, with a warning message, or
+       cause an error.
+
+       The pattern is passed to regcomp() as a zero-terminated string  by  de-
+       fault, but if the use_length or hex modifiers are set, the REG_PEND ex-
+       tension is used to pass it by length.
+
+   Testing the stack guard feature
+
+       The  stackguard  modifier  is  used  to  test the use of pcre2_set_com-
+       pile_recursion_guard(), a function that is  provided  to  enable  stack
+       availability  to  be checked during compilation (see the pcre2api docu-
+       mentation for details). If the number  specified  by  the  modifier  is
+       greater than zero, pcre2_set_compile_recursion_guard() is called to set
+       up  callback  from pcre2_compile() to a local function. The argument it
+       receives is the current nesting parenthesis depth; if this  is  greater
+       than the value given by the modifier, non-zero is returned, causing the
+       compilation to be aborted.
+
+   Using alternative character tables
+
+       The  value  specified for the tables modifier must be one of the digits
+       0, 1, 2, or 3. It causes a specific set of built-in character tables to
+       be passed to pcre2_compile(). This is used in the PCRE2 tests to  check
+       behaviour  with different character tables. The digit specifies the ta-
+       bles as follows:
+
+         0   do not pass any special character tables
+         1   the default ASCII tables, as distributed in
+               pcre2_chartables.c.dist
+         2   a set of tables defining ISO 8859 characters
+         3   a set of tables loaded by the #loadtables command
+
+       In tables 2, some characters whose codes are greater than 128 are iden-
+       tified as letters, digits, spaces, etc. Tables 3 can be used only after
+       a #loadtables command has loaded them from a binary file.  Setting  al-
+       ternate character tables and a locale are mutually exclusive.
+
+   Setting certain match controls
+
+       The following modifiers are really subject modifiers, and are described
+       under  "Subject  Modifiers"  below.  However, they may be included in a
+       pattern's modifier list, in which case they are applied to  every  sub-
+       ject  line  that is processed with that pattern. These modifiers do not
+       affect the compilation process.
+
+             aftertext                   show text after match
+             allaftertext                show text after captures
+             allcaptures                 show all captures
+             allvector                   show the entire ovector
+             allusedtext                 show all consulted text
+             altglobal                   alternative global matching
+         /g  global                      global matching
+             heapframes_size             show match data heapframes size
+             jitstack=                set size of JIT stack
+             mark                        show mark values
+             replace=            specify a replacement string
+             startchar                   show starting character when relevant
+             substitute_callout          use substitution callouts
+             substitute_extended         use PCRE2_SUBSTITUTE_EXTENDED
+             substitute_literal          use PCRE2_SUBSTITUTE_LITERAL
+             substitute_matched          use PCRE2_SUBSTITUTE_MATCHED
+             substitute_overflow_length  use PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+             substitute_replacement_only use PCRE2_SUBSTITUTE_REPLACEMENT_ONLY
+             substitute_skip=         skip substitution 
+             substitute_stop=         skip substitution  and following
+             substitute_unknown_unset    use PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+             substitute_unset_empty      use PCRE2_SUBSTITUTE_UNSET_EMPTY
+
+       These modifiers may not appear in a #pattern command. If you want  them
+       as defaults, set them in a #subject command.
+
+   Specifying literal subject lines
+
+       If  the  subject_literal modifier is present on a pattern, all the sub-
+       ject lines that it matches are taken as literal strings, with no inter-
+       pretation of backslashes. It is not possible to set  subject  modifiers
+       on  such  lines, but any that are set as defaults by a #subject command
+       are recognized.
+
+   Saving a compiled pattern
+
+       When a pattern with the push modifier is successfully compiled,  it  is
+       pushed  onto  a  stack  of compiled patterns, and pcre2test expects the
+       next line to contain a new pattern (or a command) instead of a  subject
+       line. This facility is used when saving compiled patterns to a file, as
+       described  in  the section entitled "Saving and restoring compiled pat-
+       terns" below.  If pushcopy is used instead of push, a copy of the  com-
+       piled  pattern  is  stacked,  leaving the original as current, ready to
+       match the following input lines. This provides a  way  of  testing  the
+       pcre2_code_copy()  function.   The push and pushcopy  modifiers are in-
+       compatible with compilation modifiers such as global that act at  match
+       time. Any that are specified are ignored (for the stacked copy), with a
+       warning  message,  except for replace, which causes an error. Note that
+       jitverify, which is allowed, does not carry through to  any  subsequent
+       matching that uses a stacked pattern.
+
+   Testing foreign pattern conversion
+
+       The  experimental  foreign pattern conversion functions in PCRE2 can be
+       tested by setting the convert modifier. Its argument is  a  colon-sepa-
+       rated  list  of  options,  which  set  the  equivalent  option  for the
+       pcre2_pattern_convert() function:
+
+         glob                    PCRE2_CONVERT_GLOB
+         glob_no_starstar        PCRE2_CONVERT_GLOB_NO_STARSTAR
+         glob_no_wild_separator  PCRE2_CONVERT_GLOB_NO_WILD_SEPARATOR
+         posix_basic             PCRE2_CONVERT_POSIX_BASIC
+         posix_extended          PCRE2_CONVERT_POSIX_EXTENDED
+         unset                   Unset all options
+
+       The "unset" value is useful for turning off a default that has been set
+       by a #pattern command. When one of these options is set, the input pat-
+       tern is passed to pcre2_pattern_convert(). If the  conversion  is  suc-
+       cessful,  the  result  is  reflected  in  the output and then passed to
+       pcre2_compile(). The normal utf and no_utf_check options, if set, cause
+       the PCRE2_CONVERT_UTF  and  PCRE2_CONVERT_NO_UTF_CHECK  options  to  be
+       passed to pcre2_pattern_convert().
+
+       By default, the conversion function is allowed to allocate a buffer for
+       its  output.  However, if the convert_length modifier is set to a value
+       greater than zero, pcre2test passes a buffer of the given length.  This
+       makes it possible to test the length check.
+
+       The  convert_glob_escape  and  convert_glob_separator  modifiers can be
+       used to specify the escape and separator characters for  glob  process-
+       ing, overriding the defaults, which are operating-system dependent.
+
+
+SUBJECT MODIFIERS
+
+       The modifiers that can appear in subject lines and the #subject command
+       are of two types.
+
+   Setting match options
+
+       The    following   modifiers   set   options   for   pcre2_match()   or
+       pcre2_dfa_match(). See pcreapi for a description of their effects.
+
+             anchored                   set PCRE2_ANCHORED
+             endanchored                set PCRE2_ENDANCHORED
+             dfa_restart                set PCRE2_DFA_RESTART
+             dfa_shortest               set PCRE2_DFA_SHORTEST
+             disable_recurseloop_check  set PCRE2_DISABLE_RECURSELOOP_CHECK
+             no_jit                     set PCRE2_NO_JIT
+             no_utf_check               set PCRE2_NO_UTF_CHECK
+             notbol                     set PCRE2_NOTBOL
+             notempty                   set PCRE2_NOTEMPTY
+             notempty_atstart           set PCRE2_NOTEMPTY_ATSTART
+             noteol                     set PCRE2_NOTEOL
+             partial_hard (or ph)       set PCRE2_PARTIAL_HARD
+             partial_soft (or ps)       set PCRE2_PARTIAL_SOFT
+
+       The partial matching modifiers are provided with abbreviations  because
+       they appear frequently in tests.
+
+       If  the posix or posix_nosub modifier was present on the pattern, caus-
+       ing the POSIX wrapper API to be used, the only option-setting modifiers
+       that have any effect are notbol, notempty, and noteol, causing REG_NOT-
+       BOL, REG_NOTEMPTY,  and  REG_NOTEOL,  respectively,  to  be  passed  to
+       regexec(). The other modifiers are ignored, with a warning message.
+
+       There  is one additional modifier that can be used with the POSIX wrap-
+       per. It is ignored (with a warning) if used for non-POSIX matching.
+
+             posix_startend=[:]
+
+       This causes the subject string to be  passed  to  regexec()  using  the
+       REG_STARTEND  option,  which  uses offsets to specify which part of the
+       string is searched. If only one number is  given,  the  end  offset  is
+       passed  as  the end of the subject string. For more detail of REG_STAR-
+       TEND, see the pcre2posix documentation. If the subject string  contains
+       binary  zeros  (coded  as escapes such as \x{00} because pcre2test does
+       not support actual binary zeros in its input), you must use posix_star-
+       tend to specify its length.
+
+   Setting match controls
+
+       The following modifiers affect the matching process  or  request  addi-
+       tional  information.  Some  of  them may also be specified on a pattern
+       line (see above), in which case they apply to every subject  line  that
+       is  matched against that pattern, but can be overridden by modifiers on
+       the subject.

+
+       The effects of these modifiers are described in the following sections.
+       When matching via the POSIX wrapper API, the  aftertext,  allaftertext,
+       and  ovector subject modifiers work as described below. All other modi-
+       fiers are either ignored, with a warning message, or cause an error.
+
+   Showing more text
+
+       The aftertext modifier requests that as well as outputting the part  of
+       the subject string that matched the entire pattern, pcre2test should in
+       addition output the remainder of the subject string. This is useful for
+       tests where the subject contains multiple copies of the same substring.
+       The  allaftertext  modifier  requests the same action for captured sub-
+       strings as well as the main matched substring. In each case the remain-
+       der is output on the following line with a plus character following the
+       capture number.
+
+       The allusedtext modifier requests that all the text that was  consulted
+       during  a  successful pattern match by the interpreter should be shown,
+       for both full and partial matches. This feature is  not  supported  for
+       JIT  matching,  and if requested with JIT it is ignored (with a warning
+       message). Setting this modifier affects the output if there is a  look-
+       behind  at  the start of a match, or, for a complete match, a lookahead
+       at the end, or if \K is used in the pattern. Characters that precede or
+       follow the start and end of the actual match are indicated in the  out-
+       put by '<' or '>' characters underneath them.  Here is an example:
+
+           re> /(?<=pqr)abc(?=xyz)/
+         data> 123pqrabcxyz456\=allusedtext
+          0: pqrabcxyz
+             <<<   >>>
+         data> 123pqrabcxy\=ph,allusedtext
+         Partial match: pqrabcxy
+                        <<<
+
+       The  first, complete match shows that the matched string is "abc", with
+       the preceding and following strings "pqr" and "xyz"  having  been  con-
+       sulted  during  the match (when processing the assertions). The partial
+       match can indicate only the preceding string.
+
+       The startchar modifier requests that the  starting  character  for  the
+       match  be  indicated,  if  it  is different to the start of the matched
+       string. The only time when this occurs is when \K has been processed as
+       part of the match. In this situation, the output for the matched string
+       is displayed from the starting character  instead  of  from  the  match
+       point, with circumflex characters under the earlier characters. For ex-
+       ample:
+
+           re> /abc\Kxyz/
+         data> abcxyz\=startchar
+          0: abcxyz
+             ^^^
+
+       Unlike  allusedtext, the startchar modifier can be used with JIT.  How-
+       ever, these two modifiers are mutually exclusive.
+
+   Showing the value of all capture groups
+
+       The allcaptures modifier requests that the values of all potential cap-
+       tured parentheses be output after a match. By default, only those up to
+       the highest one actually used in the match are output (corresponding to
+       the return code from pcre2_match()). Groups that did not take  part  in
+       the  match  are  output as "". This modifier is not relevant for
+       DFA matching (which does no capturing) and does not apply when  replace
+       is specified; it is ignored, with a warning message, if present.
+
+   Showing the entire ovector, for all outcomes
+
+       The allvector modifier requests that the entire ovector be shown, what-
+       ever the outcome of the match. Compare allcaptures, which shows only up
+       to  the maximum number of capture groups for the pattern, and then only
+       for a successful complete non-DFA match. This modifier, which acts  af-
+       ter  any  match  result, and also for DFA matching, provides a means of
+       checking that there are no unexpected modifications to ovector  fields.
+       Before  each match attempt, the ovector is filled with a special value,
+       and if this is found in  both  elements  of  a  capturing  pair,  ""  is  output.  After  a  successful match, this applies to all
+       groups after the maximum capture group for the pattern. In other  cases
+       it  applies to the entire ovector. After a partial match, the first two
+       elements are the only ones that should be set. After a DFA  match,  the
+       amount  of  ovector  that is used depends on the number of matches that
+       were found.
+
+   Testing pattern callouts
+
+       A callout function is supplied when pcre2test calls the library  match-
+       ing  functions,  unless callout_none is specified. Its behaviour can be
+       controlled by various modifiers listed above  whose  names  begin  with
+       callout_.  Details  are given in the section entitled "Callouts" below.
+       Testing callouts from pcre2_substitute()  is  described  separately  in
+       "Testing the substitution function" below.
+
+   Finding all matches in a string
+
+       Searching for all possible matches within a subject can be requested by
+       the  global  or altglobal modifier. After finding a match, the matching
+       function is called again to search the remainder of  the  subject.  The
+       difference  between  global  and  altglobal is that the former uses the
+       start_offset argument to pcre2_match() or  pcre2_dfa_match()  to  start
+       searching  at  a new point within the entire string (which is what Perl
+       does), whereas the latter passes over a shortened subject. This makes a
+       difference to the matching process if the pattern begins with a lookbe-
+       hind assertion (including \b or \B).
+
+       If an empty string  is  matched,  the  next  match  is  done  with  the
+       PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set, in order to search
+       for another, non-empty, match at the same point in the subject. If this
+       match  fails, the start offset is advanced, and the normal match is re-
+       tried. This imitates the way Perl handles such cases when using the  /g
+       modifier  or  the  split()  function. Normally, the start offset is ad-
+       vanced by one character, but if the newline convention recognizes  CRLF
+       as  a  newline,  and the current character is CR followed by LF, an ad-
+       vance of two characters occurs.
+
+   Testing substring extraction functions
+
+       The copy  and  get  modifiers  can  be  used  to  test  the  pcre2_sub-
+       string_copy_xxx() and pcre2_substring_get_xxx() functions.  They can be
+       given more than once, and each can specify a capture group name or num-
+       ber, for example:
+
+          abcd\=copy=1,copy=3,get=G1
+
+       If  the  #subject command is used to set default copy and/or get lists,
+       these can be unset by specifying a negative number to cancel  all  num-
+       bered groups and an empty name to cancel all named groups.
+
+       The  getall  modifier  tests pcre2_substring_list_get(), which extracts
+       all captured substrings.
+
+       If the subject line is successfully matched, the  substrings  extracted
+       by  the  convenience  functions  are  output  with C, G, or L after the
+       string number instead of a colon. This is in  addition  to  the  normal
+       full  list.  The string length (that is, the return from the extraction
+       function) is given in parentheses after each substring, followed by the
+       name when the extraction was by name.
+
+   Testing the substitution function
+
+       If the replace modifier is  set,  the  pcre2_substitute()  function  is
+       called  instead  of one of the matching functions (or after one call of
+       pcre2_match() in the case of PCRE2_SUBSTITUTE_MATCHED). Note  that  re-
+       placement  strings cannot contain commas, because a comma signifies the
+       end of a modifier. This is not thought to be an issue in  a  test  pro-
+       gram.
+
+       Specifying  a  completely  empty replacement string disables this modi-
+       fier.  However, it is possible to specify an empty replacement by  pro-
+       viding  a buffer length, as described below, for an otherwise empty re-
+       placement.
+
+       Unlike subject strings, pcre2test does not process replacement  strings
+       for  escape  sequences. In UTF mode, a replacement string is checked to
+       see if it is a valid UTF-8 string. If so, it is correctly converted  to
+       a  UTF  string of the appropriate code unit width. If it is not a valid
+       UTF-8 string, the individual code units are copied directly. This  pro-
+       vides a means of passing an invalid UTF-8 string for testing purposes.
+
+       The  following modifiers set options (in additional to the normal match
+       options) for pcre2_substitute():
+
+         global                      PCRE2_SUBSTITUTE_GLOBAL
+         substitute_extended         PCRE2_SUBSTITUTE_EXTENDED
+         substitute_literal          PCRE2_SUBSTITUTE_LITERAL
+         substitute_matched          PCRE2_SUBSTITUTE_MATCHED
+         substitute_overflow_length  PCRE2_SUBSTITUTE_OVERFLOW_LENGTH
+         substitute_replacement_only PCRE2_SUBSTITUTE_REPLACEMENT_ONLY
+         substitute_unknown_unset    PCRE2_SUBSTITUTE_UNKNOWN_UNSET
+         substitute_unset_empty      PCRE2_SUBSTITUTE_UNSET_EMPTY
+
+       See the pcre2api documentation for details of these options.
+
+       After a successful substitution, the modified string  is  output,  pre-
+       ceded  by the number of replacements. This may be zero if there were no
+       matches. Here is a simple example of a substitution test:
+
+         /abc/replace=xxx
+             =abc=abc=
+          1: =xxx=abc=
+             =abc=abc=\=global
+          2: =xxx=xxx=
+
+       Subject and replacement strings should be kept relatively short  (fewer
+       than  256 characters) for substitution tests, as fixed-size buffers are
+       used. To make it easy to test for buffer overflow, if  the  replacement
+       string  starts  with a number in square brackets, that number is passed
+       to pcre2_substitute() as the size of the output buffer,  with  the  re-
+       placement  string  starting  at  the next character. Here is an example
+       that tests the edge case:
+
+         /abc/
+             123abc123\=replace=[10]XYZ
+          1: 123XYZ123
+             123abc123\=replace=[9]XYZ
+         Failed: error -47: no more memory
+
+       The  default  action  of  pcre2_substitute()  is  to  return  PCRE2_ER-
+       ROR_NOMEMORY  when  the  output  buffer  is  too small. However, if the
+       PCRE2_SUBSTITUTE_OVERFLOW_LENGTH option is set (by  using  the  substi-
+       tute_overflow_length  modifier),  pcre2_substitute()  continues  to  go
+       through the motions of matching and substituting  (but  not  doing  any
+       callouts),  in  order  to  compute the size of buffer that is required.
+       When this happens, pcre2test shows the required  buffer  length  (which
+       includes space for the trailing zero) as part of the error message. For
+       example:
+
+         /abc/substitute_overflow_length
+             123abc123\=replace=[9]XYZ
+         Failed: error -47: no more memory: 10 code units are needed
+
+       A replacement string is ignored with POSIX and DFA matching. Specifying
+       partial  matching  provokes  an  error return ("bad option value") from
+       pcre2_substitute().
+
+   Testing substitute callouts
+
+       If the substitute_callout modifier is set, a substitution callout func-
+       tion is set up. The null_context modifier must not be set, because  the
+       address  of the callout function is passed in a match context. When the
+       callout function is called (after each substitution),  details  of  the
+       input and output strings are output. For example:
+
+         /abc/g,replace=<$0>,substitute_callout
+             abcdefabcpqr
+          1(1) Old 0 3 "abc" New 0 5 ""
+          2(1) Old 6 9 "abc" New 8 13 ""
+          2: defpqr
+
+       The  first  number  on  each  callout line is the count of matches. The
+       parenthesized number is the number of pairs that are set in the ovector
+       (that is, one more than the number of capturing groups that were  set).
+       Then are listed the offsets of the old substring, its contents, and the
+       same for the replacement.
+
+       By  default,  the substitution callout function returns zero, which ac-
+       cepts the replacement and causes matching to continue if /g  was  used.
+       Two  further modifiers can be used to test other return values. If sub-
+       stitute_skip is set to a value greater than zero the  callout  function
+       returns  +1 for the match of that number, and similarly substitute_stop
+       returns -1. These cause the replacement to be rejected, and  -1  causes
+       no  further  matching to take place. If either of them are set, substi-
+       tute_callout is assumed. For example:
+
+         /abc/g,replace=<$0>,substitute_skip=1
+             abcdefabcpqr
+          1(1) Old 0 3 "abc" New 0 5 " SKIPPED"
+          2(1) Old 6 9 "abc" New 6 11 ""
+          2: abcdefpqr
+             abcdefabcpqr\=substitute_stop=1
+          1(1) Old 0 3 "abc" New 0 5 " STOPPED"
+          1: abcdefabcpqr
+
+       If both are set for the same number, stop takes precedence. Only a sin-
+       gle skip or stop is supported, which is sufficient for testing that the
+       feature works.
+
+   Setting the JIT stack size
+
+       The jitstack modifier provides a way of setting the maximum stack  size
+       that  is  used  by the just-in-time optimization code. It is ignored if
+       JIT optimization is not being used. The value is a number of  kibibytes
+       (units  of  1024  bytes). Setting zero reverts to the default of 32KiB.
+       Providing a stack that is larger than the default is necessary only for
+       very complicated patterns. If jitstack is set  non-zero  on  a  subject
+       line it overrides any value that was set on the pattern.
+
+   Setting heap, match, and depth limits
+
+       The  heap_limit,  match_limit, and depth_limit modifiers set the appro-
+       priate limits in the match context. These values are ignored  when  the
+       find_limits or find_limits_noheap modifier is specified.
+
+   Finding minimum limits
+
+       If  the  find_limits  modifier  is present on a subject line, pcre2test
+       calls the relevant matching function several times,  setting  different
+       values    in    the    match    context   via   pcre2_set_heap_limit(),
+       pcre2_set_match_limit(), or pcre2_set_depth_limit() until it finds  the
+       smallest  value  for  each  parameter that allows the match to complete
+       without a "limit exceeded" error. The match itself may succeed or fail.
+       An alternative modifier, find_limits_noheap, omits the heap limit. This
+       is used in the standard tests, because the minimum  heap  limit  varies
+       between  systems.  If  JIT is being used, only the match limit is rele-
+       vant, and the other two are automatically omitted.
+
+       When using this modifier, the pattern should not contain any limit set-
+       tings such as (*LIMIT_MATCH=...)  within  it.  If  such  a  setting  is
+       present and is lower than the minimum matching value, the minimum value
+       cannot  be  found because pcre2_set_match_limit() etc. are only able to
+       reduce the value of an in-pattern limit; they cannot increase it.
+
+       For non-DFA matching, the minimum depth_limit number is  a  measure  of
+       how much nested backtracking happens (that is, how deeply the pattern's
+       tree  is  searched).  In the case of DFA matching, depth_limit controls
+       the depth of recursive calls of the internal function that is used  for
+       handling pattern recursion, lookaround assertions, and atomic groups.
+
+       For non-DFA matching, the match_limit number is a measure of the amount
+       of backtracking that takes place, and learning the minimum value can be
+       instructive.  For  most  simple matches, the number is quite small, but
+       for patterns with very large numbers of matching possibilities, it  can
+       become  large very quickly with increasing length of subject string. In
+       the case of DFA matching, match_limit  controls  the  total  number  of
+       calls, both recursive and non-recursive, to the internal matching func-
+       tion, thus controlling the overall amount of computing resource that is
+       used.
+
+       For  both  kinds  of  matching,  the  heap_limit  number,  which  is in
+       kibibytes (units of 1024 bytes), limits the amount of heap memory  used
+       for matching.
+
+   Showing MARK names
+
+
+       The mark modifier causes the names from backtracking control verbs that
+       are  returned from calls to pcre2_match() to be displayed. If a mark is
+       returned for a match, non-match, or partial match, pcre2test shows  it.
+       For  a  match, it is on a line by itself, tagged with "MK:". Otherwise,
+       it is added to the non-match message.
+
+   Showing memory usage
+
+       The memory modifier causes pcre2test to log the sizes of all heap  mem-
+       ory   allocation  and  freeing  calls  that  occur  during  a  call  to
+       pcre2_match() or pcre2_dfa_match(). In the latter case, heap memory  is
+       used  only  when  a match requires more internal workspace that the de-
+       fault allocation on the stack, so in many cases there will be  no  out-
+       put.  No  heap  memory  is allocated during matching with JIT. For this
+       modifier to work, the null_context modifier must not be set on both the
+       pattern and the subject, though it can be set on one or the other.
+
+   Showing the heap frame overall vector size
+
+       The  heapframes_size   modifier   is   relevant   for   matches   using
+       pcre2_match() without JIT. After a match has run (whether successful or
+       not)  the  size,  in bytes, of the allocated heap frames vector that is
+       left attached to the match data block is shown. If the matching  action
+       involved  several  calls to pcre2_match() (for example, global matching
+       or for timing) only the final value is shown.
+
+       This modifier is ignored, with a warning, for POSIX  or  DFA  matching.
+       JIT matching does not use the heap frames vector, so the size is always
+       zero,  unless there was a previous non-JIT match. Note that specifing a
+       size of zero for the output vector (see below) causes pcre2test to free
+       its match data block (and associated heap frames vector) and allocate a
+       new one.
+
+   Setting a starting offset
+
+       The offset modifier sets an offset  in  the  subject  string  at  which
+       matching starts. Its value is a number of code units, not characters.
+
+   Setting an offset limit
+
+       The  offset_limit  modifier  sets  a limit for unanchored matches. If a
+       match cannot be found starting at or before this offset in the subject,
+       a "no match" return is given. The data value is a number of code units,
+       not characters. When this modifier is used, the use_offset_limit  modi-
+       fier must have been set for the pattern; if not, an error is generated.
+
+   Setting the size of the output vector
+
+       The  ovector  modifier applies only to the subject line in which it ap-
+       pears, though of course it can also be used to set a default in a #sub-
+       ject command. It specifies the number of  pairs  of  offsets  that  are
+       available for storing matching information. The default is 15.
+
+       A  value of zero is useful when testing the POSIX API because it causes
+       regexec() to be called with a NULL capture vector. When not testing the
+       POSIX API, a value of  zero  is  used  to  cause  pcre2_match_data_cre-
+       ate_from_pattern()  to  be called, in order to create a new match block
+       of exactly the right size for the pattern. (It is not possible to  cre-
+       ate  a match block with a zero-length ovector; there is always at least
+       one pair of offsets.) The old match data block is freed.
+
+   Passing the subject as zero-terminated
+
+       By default, the subject string is passed to a native API matching func-
+       tion with its correct length. In order to test the facility for passing
+       a zero-terminated string, the zero_terminate modifier is  provided.  It
+       causes  the length to be passed as PCRE2_ZERO_TERMINATED. When matching
+       via the POSIX interface, this modifier is ignored, with a warning.
+
+       When testing pcre2_substitute(), this modifier also has the  effect  of
+       passing the replacement string as zero-terminated.
+
+   Passing a NULL context, subject, or replacement
+
+       Normally,   pcre2test   passes   a   context  block  to  pcre2_match(),
+       pcre2_dfa_match(), pcre2_jit_match()  or  pcre2_substitute().   If  the
+       null_context  modifier  is  set,  however,  NULL is passed. This is for
+       testing that the matching and substitution functions  behave  correctly
+       in  this  case  (they use default values). This modifier cannot be used
+       with the find_limits, find_limits_noheap, or  substitute_callout  modi-
+       fiers.
+
+       Similarly,  for  testing purposes, if the null_subject or null_replace-
+       ment modifier is set, the subject or replacement  string  pointers  are
+       passed as NULL, respectively, to the relevant functions.
+
+
+THE ALTERNATIVE MATCHING FUNCTION
+
+       By  default,  pcre2test  uses  the  standard  PCRE2  matching function,
+       pcre2_match() to match each subject line. PCRE2 also supports an alter-
+       native matching function, pcre2_dfa_match(), which operates in  a  dif-
+       ferent  way, and has some restrictions. The differences between the two
+       functions are described in the pcre2matching documentation.
+
+       If the dfa modifier is set, the alternative matching function is  used.
+       This  function  finds all possible matches at a given point in the sub-
+       ject. If, however, the dfa_shortest modifier is set,  processing  stops
+       after  the  first  match is found. This is always the shortest possible
+       match.
+
+
+DEFAULT OUTPUT FROM pcre2test
+
+       This section describes the output when the  normal  matching  function,
+       pcre2_match(), is being used.
+
+       When  a  match  succeeds,  pcre2test  outputs the list of captured sub-
+       strings, starting with number 0 for the string that matched  the  whole
+       pattern.  Otherwise, it outputs "No match" when the return is PCRE2_ER-
+       ROR_NOMATCH,  or  "Partial  match:"  followed by the partially matching
+       substring when the return is PCRE2_ERROR_PARTIAL. (Note  that  this  is
+       the  entire  substring  that was inspected during the partial match; it
+       may include characters before the actual match start  if  a  lookbehind
+       assertion, \K, \b, or \B was involved.)
+
+       For any other return, pcre2test outputs the PCRE2 negative error number
+       and  a  short  descriptive  phrase. If the error is a failed UTF string
+       check, the code unit offset of the start of the  failing  character  is
+       also output. Here is an example of an interactive pcre2test run.
+
+         $ pcre2test
+         PCRE2 version 10.22 2016-07-29
+
+           re> /^abc(\d+)/
+         data> abc123
+          0: abc123
+          1: 123
+         data> xyz
+         No match
+
+       Unset capturing substrings that are not followed by one that is set are
+       not shown by pcre2test unless the allcaptures modifier is specified. In
+       the following example, there are two capturing substrings, but when the
+       first  data  line is matched, the second, unset substring is not shown.
+       An "internal" unset substring is shown as "", as for the  second
+       data line.
+
+           re> /(a)|(b)/
+         data> a
+          0: a
+          1: a
+         data> b
+          0: b
+          1: 
+          2: b
+
+       If  the strings contain any non-printing characters, they are output as
+       \xhh escapes if the value is less than 256 and UTF  mode  is  not  set.
+       Otherwise they are output as \x{hh...} escapes. See below for the defi-
+       nition  of  non-printing  characters. If the aftertext modifier is set,
+       the output for substring 0 is followed  by  the  rest  of  the  subject
+       string, identified by "0+" like this:
+
+           re> /cat/aftertext
+         data> cataract
+          0: cat
+          0+ aract
+
+       If global matching is requested, the results of successive matching at-
+       tempts are output in sequence, like this:
+
+           re> /\Bi(\w\w)/g
+         data> Mississippi
+          0: iss
+          1: ss
+          0: iss
+          1: ss
+          0: ipp
+          1: pp
+
+       "No  match" is output only if the first match attempt fails. Here is an
+       example of a failure message (the offset 4 that  is  specified  by  the
+       offset modifier is past the end of the subject string):
+
+           re> /xyz/
+         data> xyz\=offset=4
+         Error -24 (bad offset value)
+
+       Note that whereas patterns can be continued over several lines (a plain
+       ">"  prompt  is used for continuations), subject lines may not. However
+       newlines can be included in a subject by means of the \n escape (or \r,
+       \r\n, etc., depending on the newline sequence setting).
+
+
+OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION
+
+       When the alternative matching function, pcre2_dfa_match(), is used, the
+       output consists of a list of all the matches that start  at  the  first
+       point in the subject where there is at least one match. For example:
+
+           re> /(tang|tangerine|tan)/
+         data> yellow tangerine\=dfa
+          0: tangerine
+          1: tang
+          2: tan
+
+       Using  the normal matching function on this data finds only "tang". The
+       longest matching string is always given first (and numbered zero).  Af-
+       ter  a PCRE2_ERROR_PARTIAL return, the output is "Partial match:", fol-
+       lowed by the partially matching substring. Note that this is the entire
+       substring that was inspected during the partial match; it  may  include
+       characters before the actual match start if a lookbehind assertion, \b,
+       or \B was involved. (\K is not supported for DFA matching.)
+
+       If global matching is requested, the search for further matches resumes
+       at the end of the longest match. For example:
+
+           re> /(tang|tangerine|tan)/g
+         data> yellow tangerine and tangy sultana\=dfa
+          0: tangerine
+          1: tang
+          2: tan
+          0: tang
+          1: tan
+          0: tan
+
+       The  alternative  matching function does not support substring capture,
+       so the modifiers that are concerned with captured  substrings  are  not
+       relevant.
+
+
+RESTARTING AFTER A PARTIAL MATCH
+
+       When  the  alternative matching function has given the PCRE2_ERROR_PAR-
+       TIAL return, indicating that the subject partially matched the pattern,
+       you can restart the match with additional subject data by means of  the
+       dfa_restart modifier. For example:
+
+           re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+         data> 23ja\=ps,dfa
+         Partial match: 23ja
+         data> n05\=dfa,dfa_restart
+          0: n05
+
+       For  further  information  about partial matching, see the pcre2partial
+       documentation.
+
+
+CALLOUTS
+
+       If the pattern contains any callout requests, pcre2test's callout func-
+       tion is called during matching unless callout_none is  specified.  This
+       works with both matching functions, and with JIT, though there are some
+       differences  in behaviour. The output for callouts with numerical argu-
+       ments and those with string arguments is slightly different.
+
+   Callouts with numerical arguments
+
+       By default, the callout function displays the callout number, the start
+       and current positions in the subject text at the callout time, and  the
+       next pattern item to be tested. For example:
+
+         --->pqrabcdef
+           0    ^  ^     \d
+
+       This  output  indicates  that callout number 0 occurred for a match at-
+       tempt starting at the fourth character of the subject string, when  the
+       pointer  was  at  the seventh character, and when the next pattern item
+       was \d. Just one circumflex is output if the start  and  current  posi-
+       tions are the same, or if the current position precedes the start posi-
+       tion, which can happen if the callout is in a lookbehind assertion.
+
+       Callouts numbered 255 are assumed to be automatic callouts, inserted as
+       a result of the auto_callout pattern modifier. In this case, instead of
+       showing  the  callout  number, the offset in the pattern, preceded by a
+       plus, is output. For example:
+
+           re> /\d?[A-E]\*/auto_callout
+         data> E*
+         --->E*
+          +0 ^      \d?
+          +3 ^      [A-E]
+          +8 ^^     \*
+         +10 ^ ^
+          0: E*
+
+       If a pattern contains (*MARK) items, an additional line is output when-
+       ever a change of latest mark is passed to the callout function. For ex-
+       ample:
+
+           re> /a(*MARK:X)bc/auto_callout
+         data> abc
+         --->abc
+          +0 ^       a
+          +1 ^^      (*MARK:X)
+         +10 ^^      b
+         Latest Mark: X
+         +11 ^ ^     c
+         +12 ^  ^
+          0: abc
+
+       The mark changes between matching "a" and "b", but stays the  same  for
+       the  rest  of  the match, so nothing more is output. If, as a result of
+       backtracking, the mark reverts to being unset, the  text  ""  is
+       output.
+
+   Callouts with string arguments
+
+       The output for a callout with a string argument is similar, except that
+       instead  of outputting a callout number before the position indicators,
+       the callout string and its offset in the pattern string are output  be-
+       fore  the  reflection  of the subject string, and the subject string is
+       reflected for each callout. For example:
+
+           re> /^ab(?C'first')cd(?C"second")ef/
+         data> abcdefg
+         Callout (7): 'first'
+         --->abcdefg
+             ^ ^         c
+         Callout (20): "second"
+         --->abcdefg
+             ^   ^       e
+          0: abcdef
+
+
+   Callout modifiers
+
+       The callout function in pcre2test returns zero (carry on  matching)  by
+       default,  but  you can use a callout_fail modifier in a subject line to
+       change this and other parameters of the callout (see below).
+
+       If the callout_capture modifier is set, the current captured groups are
+       output when a callout occurs. This is useful only for non-DFA matching,
+       as pcre2_dfa_match() does not support capturing,  so  no  captures  are
+       ever shown.
+
+       The normal callout output, showing the callout number or pattern offset
+       (as  described above) is suppressed if the callout_no_where modifier is
+       set.
+
+       When using the interpretive  matching  function  pcre2_match()  without
+       JIT,  setting  the callout_extra modifier causes additional output from
+       pcre2test's callout function to be generated. For the first callout  in
+       a  match  attempt at a new starting position in the subject, "New match
+       attempt" is output. If there has been a backtrack since the last  call-
+       out (or start of matching if this is the first callout), "Backtrack" is
+       output,  followed  by  "No other matching paths" if the backtrack ended
+       the previous match attempt. For example:
+
+          re> /(a+)b/auto_callout,no_start_optimize,no_auto_possess
+         data> aac\=callout_extra
+         New match attempt
+         --->aac
+          +0 ^       (
+          +1 ^       a+
+          +3 ^ ^     )
+          +4 ^ ^     b
+         Backtrack
+         --->aac
+          +3 ^^      )
+          +4 ^^      b
+         Backtrack
+         No other matching paths
+         New match attempt
+         --->aac
+          +0  ^      (
+          +1  ^      a+
+          +3  ^^     )
+          +4  ^^     b
+         Backtrack
+         No other matching paths
+         New match attempt
+         --->aac
+          +0   ^     (
+          +1   ^     a+
+         Backtrack
+         No other matching paths
+         New match attempt
+         --->aac
+          +0    ^    (
+          +1    ^    a+
+         No match
+
+       Notice that various optimizations must be turned off if  you  want  all
+       possible  matching  paths  to  be  scanned. If no_start_optimize is not
+       used, there is an immediate "no match", without any  callouts,  because
+       the  starting  optimization  fails to find "b" in the subject, which it
+       knows must be present for any match. If no_auto_possess  is  not  used,
+       the  "a+"  item is turned into "a++", which reduces the number of back-
+       tracks.
+
+       The callout_extra modifier has no effect if used with the DFA  matching
+       function, or with JIT.
+
+   Return values from callouts
+
+       The  default  return  from  the  callout function is zero, which allows
+       matching to continue. The callout_fail modifier can be given one or two
+       numbers. If there is only one number, 1 is returned instead of 0 (caus-
+       ing matching to backtrack) when a callout of that number is reached. If
+       two numbers (:) are given, 1 is  returned  when  callout    is
+       reached  and  there  have been at least  callouts. The callout_error
+       modifier is similar, except that PCRE2_ERROR_CALLOUT is returned, caus-
+       ing the entire matching process to be aborted. If both these  modifiers
+       are  set  for  the same callout number, callout_error takes precedence.
+       Note that callouts with string arguments are always  given  the  number
+       zero.
+
+       The  callout_data  modifier can be given an unsigned or a negative num-
+       ber.  This is set as the "user data" that is  passed  to  the  matching
+       function,  and  passed  back  when the callout function is invoked. Any
+       value other than zero is used as  a  return  from  pcre2test's  callout
+       function.
+
+       Inserting callouts can be helpful when using pcre2test to check compli-
+       cated  regular expressions. For further information about callouts, see
+       the pcre2callout documentation.
+
+
+NON-PRINTING CHARACTERS
+
+       When pcre2test is outputting text in the compiled version of a pattern,
+       bytes other than 32-126 are always treated as  non-printing  characters
+       and are therefore shown as hex escapes.
+
+       When  pcre2test  is outputting text that is a matched part of a subject
+       string, it behaves in the same way, unless a different locale has  been
+       set  for the pattern (using the locale modifier). In this case, the is-
+       print() function is used to distinguish printing and non-printing char-
+       acters.
+
+
+SAVING AND RESTORING COMPILED PATTERNS
+
+       It is possible to save compiled patterns on disc or elsewhere, and  re-
+       load  them  later, subject to a number of restrictions. JIT data cannot
+       be saved. The host on which the patterns are reloaded must  be  running
+       the same version of PCRE2, with the same code unit width, and must also
+       have  the  same  endianness,  pointer width and PCRE2_SIZE type. Before
+       compiled patterns can be saved they must be serialized, that  is,  con-
+       verted  to a stream of bytes. A single byte stream may contain any num-
+       ber of compiled patterns, but they must all use the same character  ta-
+       bles.  A  single copy of the tables is included in the byte stream (its
+       size is 1088 bytes).
+
+       The functions whose names begin with pcre2_serialize_ are used for  se-
+       rializing  and de-serializing. They are described in the pcre2serialize
+       documentation. In this section we describe the  features  of  pcre2test
+       that can be used to test these functions.
+
+       Note  that  "serialization" in PCRE2 does not convert compiled patterns
+       to an abstract format like Java or .NET. It  just  makes  a  reloadable
+       byte code stream.  Hence the restrictions on reloading mentioned above.
+
+       In  pcre2test,  when  a pattern with push modifier is successfully com-
+       piled, it is pushed onto a stack of compiled  patterns,  and  pcre2test
+       expects  the next line to contain a new pattern (or command) instead of
+       a subject line. By contrast, the pushcopy modifier causes a copy of the
+       compiled pattern to be stacked, leaving the original available for  im-
+       mediate  matching.  By using push and/or pushcopy, a number of patterns
+       can be compiled and retained. These  modifiers  are  incompatible  with
+       posix, and control modifiers that act at match time are ignored (with a
+       message)  for the stacked patterns. The jitverify modifier applies only
+       at compile time.
+
+       The command
+
+         #save 
+
+       causes all the stacked patterns to be serialized and the result written
+       to the named file. Afterwards, all the stacked patterns are freed.  The
+       command
+
+         #load 
+
+       reads  the  data in the file, and then arranges for it to be de-serial-
+       ized, with the resulting compiled patterns added to the pattern  stack.
+       The  pattern  on the top of the stack can be retrieved by the #pop com-
+       mand, which must be followed by  lines  of  subjects  that  are  to  be
+       matched  with  the pattern, terminated as usual by an empty line or end
+       of file. This command may be followed by  a  modifier  list  containing
+       only  control  modifiers that act after a pattern has been compiled. In
+       particular, hex, posix, posix_nosub, push, and  pushcopy  are  not  al-
+       lowed,  nor  are  any option-setting modifiers.  The JIT modifiers are,
+       however permitted. Here is an example that saves and reloads  two  pat-
+       terns.
+
+         /abc/push
+         /xyz/push
+         #save tempfile
+         #load tempfile
+         #pop info
+         xyz
+
+         #pop jit,bincode
+         abc
+
+       If  jitverify  is  used with #pop, it does not automatically imply jit,
+       which is different behaviour from when it is used on a pattern.
+
+       The #popcopy command is analogous to the pushcopy modifier in  that  it
+       makes current a copy of the topmost stack pattern, leaving the original
+       still on the stack.

+.TH PCRE2UNICODE 3 "04 February 2023" "PCRE2 10.43"
+.SH NAME
+PCRE - Perl-compatible regular expressions (revised API)
+.SH "UNICODE AND UTF SUPPORT"
+.rs
+.sp
+PCRE2 is normally built with Unicode support, though if you do not need it, you
+can build it without, in which case the library will be smaller. With Unicode
+support, PCRE2 has knowledge of Unicode character properties and can process
+strings of text in UTF-8, UTF-16, and UTF-32 format (depending on the code unit
+width), but this is not the default. Unless specifically requested, PCRE2
+treats each code unit in a string as one character.
+.P
+There are two ways of telling PCRE2 to switch to UTF mode, where characters may
+consist of more than one code unit and the range of values is constrained. The
+program can call
+.\" HREF
+\fBpcre2_compile()\fP
+.\"
+with the PCRE2_UTF option, or the pattern may start with the sequence (*UTF).
+However, the latter facility can be locked out by the PCRE2_NEVER_UTF option.
+That is, the programmer can prevent the supplier of the pattern from switching
+to UTF mode.
+.P
+Note that the PCRE2_MATCH_INVALID_UTF option (see
+.\" HTML 
+.\" 
+below)
+.\"
+forces PCRE2_UTF to be set.
+.P
+In UTF mode, both the pattern and any subject strings that are matched against
+it are treated as UTF strings instead of strings of individual one-code-unit
+characters. There are also some other changes to the way characters are
+handled, as documented below.
+.
+.
+.SH "UNICODE PROPERTY SUPPORT"
+.rs
+.sp
+When PCRE2 is built with Unicode support, the escape sequences \ep{..},
+\eP{..}, and \eX can be used. This is not dependent on the PCRE2_UTF setting.
+The Unicode properties that can be tested are a subset of those that Perl
+supports. Currently they are limited to the general category properties such as
+Lu for an upper case letter or Nd for a decimal number, the derived properties
+Any and LC (synonym L&), the Unicode script names such as Arabic or Han,
+Bidi_Class, Bidi_Control, and a few binary properties.
+.P
+The full lists are given in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+and
+.\" HREF
+\fBpcre2syntax\fP
+.\"
+documentation. In general, only the short names for properties are supported.
+For example, \ep{L} matches a letter. Its longer synonym, \ep{Letter}, is not
+supported. Furthermore, in Perl, many properties may optionally be prefixed by
+"Is", for compatibility with Perl 5.6. PCRE2 does not support this.
+.
+.
+.SH "WIDE CHARACTERS AND UTF MODES"
+.rs
+.sp
+Code points less than 256 can be specified in patterns by either braced or
+unbraced hexadecimal escape sequences (for example, \ex{b3} or \exb3). Larger
+values have to use braced sequences. Unbraced octal code points up to \e777 are
+also recognized; larger ones can be coded using \eo{...}.
+.P
+The escape sequence \eN{U+} is recognized as another way of
+specifying a Unicode character by code point in a UTF mode. It is not allowed
+in non-UTF mode.
+.P
+In UTF mode, repeat quantifiers apply to complete UTF characters, not to
+individual code units.
+.P
+In UTF mode, the dot metacharacter matches one UTF character instead of a
+single code unit.
+.P
+In UTF mode, capture group names are not restricted to ASCII, and may contain
+any Unicode letters and decimal digits, as well as underscore.
+.P
+The escape sequence \eC can be used to match a single code unit in UTF mode,
+but its use can lead to some strange effects because it breaks up multi-unit
+characters (see the description of \eC in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation). For this reason, there is a build-time option that disables
+support for \eC completely. There is also a less draconian compile-time option
+for locking out the use of \eC when a pattern is compiled.
+.P
+The use of \eC is not supported by the alternative matching function
+\fBpcre2_dfa_match()\fP when in UTF-8 or UTF-16 mode, that is, when a character
+may consist of more than one code unit. The use of \eC in these modes provokes
+a match-time error. Also, the JIT optimization does not support \eC in these
+modes. If JIT optimization is requested for a UTF-8 or UTF-16 pattern that
+contains \eC, it will not succeed, and so when \fBpcre2_match()\fP is called,
+the matching will be carried out by the interpretive function.
+.P
+The character escapes \eb, \eB, \ed, \eD, \es, \eS, \ew, and \eW correctly test
+characters of any code value, but, by default, the characters that PCRE2
+recognizes as digits, spaces, or word characters remain the same set as in
+non-UTF mode, all with code points less than 256. This remains true even when
+PCRE2 is built to include Unicode support, because to do otherwise would slow
+down matching in many common cases. Note that this also applies to \eb
+and \eB, because they are defined in terms of \ew and \eW. If you want
+to test for a wider sense of, say, "digit", you can use explicit Unicode
+property tests such as \ep{Nd}. Alternatively, if you set the PCRE2_UCP option,
+the way that the character escapes work is changed so that Unicode properties
+are used to determine which characters match, though there are some options
+that suppress this for individual escapes. For details see the section on
+.\" HTML 
+.\" 
+generic character types
+.\"
+in the
+.\" HREF
+\fBpcre2pattern\fP
+.\"
+documentation.
+.P
+Like the escapes, characters that match the POSIX named character classes are
+all low-valued characters unless the PCRE2_UCP option is set, but there is an
+option to override this.
+.P
+In contrast to the character escapes and character classes, the special
+horizontal and vertical white space escapes (\eh, \eH, \ev, and \eV) do match
+all the appropriate Unicode characters, whether or not PCRE2_UCP is set.
+.
+.
+.SH "UNICODE CASE-EQUIVALENCE"
+.rs
+.sp
+If either PCRE2_UTF or PCRE2_UCP is set, upper/lower case processing makes use
+of Unicode properties except for characters whose code points are less than 128
+and that have at most two case-equivalent values. For these, a direct table
+lookup is used for speed. A few Unicode characters such as Greek sigma have
+more than two code points that are case-equivalent, and these are treated
+specially. Setting PCRE2_UCP without PCRE2_UTF allows Unicode-style case
+processing for non-UTF character encodings such as UCS-2.
+.P
+There are two ASCII characters (S and K) that, in addition to their ASCII lower
+case equivalents, have a non-ASCII one as well (long S and Kelvin sign).
+Recognition of these non-ASCII characters as case-equivalent to their ASCII
+counterparts can be disabled by setting the PCRE2_EXTRA_CASELESS_RESTRICT
+option. When this is set, all characters in a case equivalence must either be
+ASCII or non-ASCII; there can be no mixing.
+.
+.
+.\" HTML 
+.SH "SCRIPT RUNS"
+.rs
+.sp
+The pattern constructs (*script_run:...) and (*atomic_script_run:...), with
+synonyms (*sr:...) and (*asr:...), verify that the string matched within the
+parentheses is a script run. In concept, a script run is a sequence of
+characters that are all from the same Unicode script. However, because some
+scripts are commonly used together, and because some diacritical and other
+marks are used with multiple scripts, it is not that simple.
+.P
+Every Unicode character has a Script property, mostly with a value
+corresponding to the name of a script, such as Latin, Greek, or Cyrillic. There
+are also three special values:
+.P
+"Unknown" is used for code points that have not been assigned, and also for the
+surrogate code points. In the PCRE2 32-bit library, characters whose code
+points are greater than the Unicode maximum (U+10FFFF), which are accessible
+only in non-UTF mode, are assigned the Unknown script.
+.P
+"Common" is used for characters that are used with many scripts. These include
+punctuation, emoji, mathematical, musical, and currency symbols, and the ASCII
+digits 0 to 9.
+.P
+"Inherited" is used for characters such as diacritical marks that modify a
+previous character. These are considered to take on the script of the character
+that they modify.
+.P
+Some Inherited characters are used with many scripts, but many of them are only
+normally used with a small number of scripts. For example, U+102E0 (Coptic
+Epact thousands mark) is used only with Arabic and Coptic. In order to make it
+possible to check this, a Unicode property called Script Extension exists. Its
+value is a list of scripts that apply to the character. For the majority of
+characters, the list contains just one script, the same one as the Script
+property. However, for characters such as U+102E0 more than one Script is
+listed. There are also some Common characters that have a single, non-Common
+script in their Script Extension list.
+.P
+The next section describes the basic rules for deciding whether a given string
+of characters is a script run. Note, however, that there are some special cases
+involving the Chinese Han script, and an additional constraint for decimal
+digits. These are covered in subsequent sections.
+.
+.
+.SS "Basic script run rules"
+.rs
+.sp
+A string that is less than two characters long is a script run. This is the
+only case in which an Unknown character can be part of a script run. Longer
+strings are checked using only the Script Extensions property, not the basic
+Script property.
+.P
+If a character's Script Extension property is the single value "Inherited", it
+is always accepted as part of a script run. This is also true for the property
+"Common", subject to the checking of decimal digits described below. All the
+remaining characters in a script run must have at least one script in common in
+their Script Extension lists. In set-theoretic terminology, the intersection of
+all the sets of scripts must not be empty.
+.P
+A simple example is an Internet name such as "google.com". The letters are all
+in the Latin script, and the dot is Common, so this string is a script run.
+However, the Cyrillic letter "o" looks exactly the same as the Latin "o"; a
+string that looks the same, but with Cyrillic "o"s is not a script run.
+.P
+More interesting examples involve characters with more than one script in their
+Script Extension. Consider the following characters:
+.sp
+  U+060C  Arabic comma
+  U+06D4  Arabic full stop
+.sp
+The first has the Script Extension list Arabic, Hanifi Rohingya, Syriac, and
+Thaana; the second has just Arabic and Hanifi Rohingya. Both of them could
+appear in script runs of either Arabic or Hanifi Rohingya. The first could also
+appear in Syriac or Thaana script runs, but the second could not.
+.
+.
+.SS "The Chinese Han script"
+.rs
+.sp
+The Chinese Han script is commonly used in conjunction with other scripts for
+writing certain languages. Japanese uses the Hiragana and Katakana scripts
+together with Han; Korean uses Hangul and Han; Taiwanese Mandarin uses Bopomofo
+and Han. These three combinations are treated as special cases when checking
+script runs and are, in effect, "virtual scripts". Thus, a script run may
+contain a mixture of Hiragana, Katakana, and Han, or a mixture of Hangul and
+Han, or a mixture of Bopomofo and Han, but not, for example, a mixture of
+Hangul and Bopomofo and Han. PCRE2 (like Perl) follows Unicode's Technical
+Standard 39 ("Unicode Security Mechanisms", http://unicode.org/reports/tr39/)
+in allowing such mixtures.
+.
+.
+.SS "Decimal digits"
+.rs
+.sp
+Unicode contains many sets of 10 decimal digits in different scripts, and some
+scripts (including the Common script) contain more than one set. Some of these
+decimal digits them are visually indistinguishable from the common ASCII
+digits. In addition to the script checking described above, if a script run
+contains any decimal digits, they must all come from the same set of 10
+adjacent characters.
+.
+.
+.SH "VALIDITY OF UTF STRINGS"
+.rs
+.sp
+When the PCRE2_UTF option is set, the strings passed as patterns and subjects
+are (by default) checked for validity on entry to the relevant functions. If an
+invalid UTF string is passed, a negative error code is returned. The code unit
+offset to the offending character can be extracted from the match data block by
+calling \fBpcre2_get_startchar()\fP, which is used for this purpose after a UTF
+error.
+.P
+In some situations, you may already know that your strings are valid, and
+therefore want to skip these checks in order to improve performance, for
+example in the case of a long subject string that is being scanned repeatedly.
+If you set the PCRE2_NO_UTF_CHECK option at compile time or at match time,
+PCRE2 assumes that the pattern or subject it is given (respectively) contains
+only valid UTF code unit sequences.
+.P
+If you pass an invalid UTF string when PCRE2_NO_UTF_CHECK is set, the result
+is undefined and your program may crash or loop indefinitely or give incorrect
+results. There is, however, one mode of matching that can handle invalid UTF
+subject strings. This is enabled by passing PCRE2_MATCH_INVALID_UTF to
+\fBpcre2_compile()\fP and is discussed below in the next section. The rest of
+this section covers the case when PCRE2_MATCH_INVALID_UTF is not set.
+.P
+Passing PCRE2_NO_UTF_CHECK to \fBpcre2_compile()\fP just disables the UTF check
+for the pattern; it does not also apply to subject strings. If you want to
+disable the check for a subject string you must pass this same option to
+\fBpcre2_match()\fP or \fBpcre2_dfa_match()\fP.
+.P
+UTF-16 and UTF-32 strings can indicate their endianness by special code knows
+as a byte-order mark (BOM). The PCRE2 functions do not handle this, expecting
+strings to be in host byte order.
+.P
+Unless PCRE2_NO_UTF_CHECK is set, a UTF string is checked before any other
+processing takes place. In the case of \fBpcre2_match()\fP and
+\fBpcre2_dfa_match()\fP calls with a non-zero starting offset, the check is
+applied only to that part of the subject that could be inspected during
+matching, and there is a check that the starting offset points to the first
+code unit of a character or to the end of the subject. If there are no
+lookbehind assertions in the pattern, the check starts at the starting offset.
+Otherwise, it starts at the length of the longest lookbehind before the
+starting offset, or at the start of the subject if there are not that many
+characters before the starting offset. Note that the sequences \eb and \eB are
+one-character lookbehinds.
+.P
+In addition to checking the format of the string, there is a check to ensure
+that all code points lie in the range U+0 to U+10FFFF, excluding the surrogate
+area. The so-called "non-character" code points are not excluded because
+Unicode corrigendum #9 makes it clear that they should not be.
+.P
+Characters in the "Surrogate Area" of Unicode are reserved for use by UTF-16,
+where they are used in pairs to encode code points with values greater than
+0xFFFF. The code points that are encoded by UTF-16 pairs are available
+independently in the UTF-8 and UTF-32 encodings. (In other words, the whole
+surrogate thing is a fudge for UTF-16 which unfortunately messes up UTF-8 and
+UTF-32.)
+.P
+Setting PCRE2_NO_UTF_CHECK at compile time does not disable the error that is
+given if an escape sequence for an invalid Unicode code point is encountered in
+the pattern. If you want to allow escape sequences such as \ex{d800} (a
+surrogate code point) you can set the PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES extra
+option. However, this is possible only in UTF-8 and UTF-32 modes, because these
+values are not representable in UTF-16.
+.

+.SH "MATCHING IN INVALID UTF STRINGS"
+.rs
+.sp
+You can run pattern matches on subject strings that may contain invalid UTF
+sequences if you call \fBpcre2_compile()\fP with the PCRE2_MATCH_INVALID_UTF
+option. This is supported by \fBpcre2_match()\fP, including JIT matching, but
+not by \fBpcre2_dfa_match()\fP. When PCRE2_MATCH_INVALID_UTF is set, it forces
+PCRE2_UTF to be set as well. Note, however, that the pattern itself must be a
+valid UTF string.
+.P
+If you do not set PCRE2_MATCH_INVALID_UTF when calling \fBpcre2_compile\fP, and
+you are not certain that your subject strings are valid UTF sequences, you
+should not make use of the JIT "fast path" function \fBpcre2_jit_match()\fP
+because it bypasses sanity checks, including the one for UTF validity. An
+invalid string may cause undefined behaviour, including looping, crashing, or
+giving the wrong answer.
+.P
+Setting PCRE2_MATCH_INVALID_UTF does not affect what \fBpcre2_compile()\fP
+generates, but if \fBpcre2_jit_compile()\fP is subsequently called, it does
+generate different code. If JIT is not used, the option affects the behaviour
+of the interpretive code in \fBpcre2_match()\fP. When PCRE2_MATCH_INVALID_UTF
+is set at compile time, PCRE2_NO_UTF_CHECK is ignored at match time.
+.P
+In this mode, an invalid code unit sequence in the subject never matches any
+pattern item. It does not match dot, it does not match \ep{Any}, it does not
+even match negative items such as [^X]. A lookbehind assertion fails if it
+encounters an invalid sequence while moving the current point backwards. In
+other words, an invalid UTF code unit sequence acts as a barrier which no match
+can cross.
+.P
+You can also think of this as the subject being split up into fragments of
+valid UTF, delimited internally by invalid code unit sequences. The pattern is
+matched fragment by fragment. The result of a successful match, however, is
+given as code unit offsets in the entire subject string in the usual way. There
+are a few points to consider:
+.P
+The internal boundaries are not interpreted as the beginnings or ends of lines
+and so do not match circumflex or dollar characters in the pattern.
+.P
+If \fBpcre2_match()\fP is called with an offset that points to an invalid
+UTF-sequence, that sequence is skipped, and the match starts at the next valid
+UTF character, or the end of the subject.
+.P
+At internal fragment boundaries, \eb and \eB behave in the same way as at the
+beginning and end of the subject. For example, a sequence such as \ebWORD\eb
+would match an instance of WORD that is surrounded by invalid UTF code units.
+.P
+Using PCRE2_MATCH_INVALID_UTF, an application can run matches on arbitrary
+data, knowing that any matched strings that are returned are valid UTF. This
+can be useful when searching for UTF text in executable or other binary files.
+.P
+Note, however, that the 16-bit and 32-bit PCRE2 libraries process strings as
+sequences of uint16_t or uint32_t code points. They cannot find valid UTF
+sequences within an arbitrary string of bytes unless such sequences are
+suitably aligned.

+# func_quote_arg MODEs ARG
+# ------------------------
+# Quote one ARG to be evaled later.  MODEs argument may contain zero or more
+# specifiers listed below separated by ',' character.  This function returns two
+# values:
+#   i) func_quote_arg_result
+#      double-quoted (when needed), suitable for a subsequent eval
+#  ii) func_quote_arg_unquoted_result
+#      has all characters that are still active within double
+#      quotes backslashified.  Available only if 'unquoted' is specified.
+#
+# Available modes:
+# ----------------
+# 'eval' (default)
+#       - escape shell special characters
+# 'expand'
+#       - the same as 'eval';  but do not quote variable references
+# 'pretty'
+#       - request aesthetic output, i.e. '"a b"' instead of 'a\ b'.  This might
+#         be used later in func_quote to get output like: 'echo "a b"' instead
+#         of 'echo a\ b'.  This is slower than default on some shells.
+# 'unquoted'
+#       - produce also $func_quote_arg_unquoted_result which does not contain
+#         wrapping double-quotes.
+#
+# Examples for 'func_quote_arg pretty,unquoted string':
+#
+#   string      | *_result              | *_unquoted_result
+#   ------------+-----------------------+-------------------

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# Copyright'.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug in processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##

+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed

+# expanded when the contents are evaled.

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also link it with them as well. e.g. you should link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threads programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)

+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

+/* PCRE2 is written in Standard C, but there are a few non-standard things it
+can cope with, allowing it to run on SunOS4 and other "close to standard"
+systems.
+
+In environments that support the GNU autotools, config.h.in is converted into
+config.h by the "configure" script. In environments that use CMake,
+config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
+hand" without using "configure" or CMake, you should copy the distributed
+config.h.generic to config.h, and edit the macro definitions to be the way you
+need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
+so that config.h is included at the start of every source.
+
+Alternatively, you can avoid editing by using -D on the compiler command line
+to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
+but if you do, default values will be taken from config.h for non-boolean
+macros that are not defined on the command line.
+
+Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be
+defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All
+such macros are listed as a commented #undef in config.h.generic. Macros such
+as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
+surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
+
+PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
+HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
+sure both macros are undefined; an emulation function will then be used. */

+/* PCRE2 is written in Standard C, but there are a few non-standard things it
+can cope with, allowing it to run on SunOS4 and other "close to standard"
+systems.
+
+In environments that support the GNU autotools, config.h.in is converted into
+config.h by the "configure" script. In environments that use CMake,
+config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
+hand" without using "configure" or CMake, you should copy the distributed
+config.h.generic to config.h, and edit the macro definitions to be the way you
+need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
+so that config.h is included at the start of every source.
+
+Alternatively, you can avoid editing by using -D on the compiler command line
+to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
+but if you do, default values will be taken from config.h for non-boolean
+macros that are not defined on the command line.
+
+Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be
+defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All
+such macros are listed as a commented #undef in config.h.generic. Macros such
+as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
+surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
+
+PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
+HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
+sure both macros are undefined; an emulation function will then be used. */

+A value of 1 means that auto-possessification is OK. For example, the second

+columns apply to items that cannot be repeated, so there is no need to have
+rows for them. Note that OP_DIGIT etc. are generated only when PCRE_UCP is
+*not* set. When it is set, \d etc. are converted into OP_(NOT_)PROP codes. */

+          Only WORD actually needs all four entries, but using repeats for the

+

+          characters. One or the other is used, depending on whether the check
+          is for a general or a particular category. However, in both cases the
+          category contains more characters than the specials that are defined
+          for the property being tested against. Therefore, it cannot be used
+          in a NOTPROP case.
+
+          Example: the row for WORD contains ucp_L, ucp_N, ucp_P, ucp_Po.

+encountered in a character class. It checks whether this is followed by a
+sequence of characters terminated by a matching ":]" or ".]" or "=]". If we
+reach an unescaped ']' without the special preceding character, return FALSE.
+
+Originally, this function only recognized a sequence of letters between the
+terminators, but it seems that Perl recognizes any sequence of characters,
+though of course unknown POSIX names are subsequently rejected. Perl gives an
+"Unknown POSIX class" error for [:f\oo:] for example, where previously PCRE
+didn't consider this to be a POSIX class. Likewise for [:1234:].
+
+The problem in trying to be exactly like Perl is in the handling of escapes. We
+have to be sure that [abc[:x\]pqr] is *not* treated as containing a POSIX
+class, but [abc[:x\]pqr:]] is (so that an error can be generated). The code
+below handles the special cases \\ and \], but does not try to do any other
+escape processing. This makes it different from Perl for cases such as
+[:l\ower:] where Perl recognizes it as the POSIX class "lower" but PCRE does
+not recognize "l\ower". This is a lesser evil than not diagnosing bad classes
+when Perl does, I think.
+
+A user pointed out that PCRE was rejecting [:a[:digit:]] whereas Perl was not.
+It seems that the appearance of a nested POSIX class supersedes an apparent
+external class. For example, [:a[:digit:]b:] matches "a", "b", ":", or
+a digit. This is handled by returning FALSE if the start of a new group with
+the same terminator is encountered, since the next closing sequence must close
+the nested group, not the outer one.
+
+In Perl, unescaped square brackets may also appear as part of class names. For
+example, [:a[:abc]b:] gives unknown POSIX class "[:abc]b:]". However, for
+[:a[:abc]b][b:] it gives unknown POSIX class "[:abc]b][b:]", which does not
+seem right at all. PCRE does not allow closing square brackets in POSIX class
+names.

+/* This module contains the external function pcre2_dfa_match(), which is an
+alternative matching function that uses a sort of DFA algorithm (not a true
+FSM). This is NOT Perl-compatible, but it has advantages in certain
+applications. */
+
+
+/* NOTE ABOUT PERFORMANCE: A user of this function sent some code that improved
+the performance of his patterns greatly. I could not use it as it stood, as it
+was not thread safe, and made assumptions about pattern sizes. Also, it caused
+test 7 to loop, and test 9 to crash with a segfault.
+
+The issue is the check for duplicate states, which is done by a simple linear
+search up the state list. (Grep for "duplicate" below to find the code.) For
+many patterns, there will never be many states active at one time, so a simple
+linear search is fine. In patterns that have many active states, it might be a
+bottleneck. The suggested code used an indexing scheme to remember which states
+had previously been used for each character, and avoided the linear search when
+it knew there was no chance of a duplicate. This was implemented when adding
+states to the state lists.
+
+I wrote some thread-safe, not-limited code to try something similar at the time
+of checking for duplicates (instead of when adding states), using index vectors
+on the stack. It did give a 13% improvement with one specially constructed
+pattern for certain subject strings, but on other strings and on many of the
+simpler patterns in the test suite it did worse. The major problem, I think,
+was the extra time to initialize the index. This had to be done for each call
+of internal_dfa_match(). (The supplied patch used a static vector, initialized
+only once - I suspect this was the cause of the problems with the tests.)
+
+Overall, I concluded that the gains in some cases did not outweigh the losses
+in others, so I abandoned this code. */

+/***************************************************************************
+Fuzzer driver for PCRE2. Given an arbitrary string of bytes and a length, it
+tries to compile and match it, deriving options from the string itself. If
+STANDALONE is defined, a main program that calls the driver with the contents
+of specified files is compiled, and commentary on what is happening is output.
+If an argument starts with '=' the rest of it it is taken as a literal string
+rather than a file name. This allows easy testing of short strings.

+the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
+is enabled. When UTF-8 support is not enabled, the definitions use character
+literals. Both character and string versions of each character are needed, and
+there are some longer strings as well.
+
+This means that, on EBCDIC platforms, the PCRE2 library can handle either
+EBCDIC, or UTF-8, but not both. To support both in the same compiled library
+would need different lookups depending on whether PCRE2_UTF was set or not.
+This would make it impossible to use characters in switch/case statements,
+which would reduce performance. For a theoretical use (which nobody has asked
+for) in a minority area (EBCDIC platforms), this is not sensible. Any
+application that did need both could compile two versions of the library, using
+macros to give the functions distinct names. */

+Short summary about the backtracking mechanism empolyed by the jit code generator:
+
+The code generator follows the recursive nature of the PERL compatible regular
+expressions. The basic blocks of regular expressions are condition checkers
+whose execute different commands depending on the result of the condition check.
+The relationship between the operators can be horizontal (concatenation) and
+vertical (sub-expression) (See struct backtrack_common for more details).
+
+  'ab' - 'a' and 'b' regexps are concatenated
+  'a+' - 'a' is the sub-expression of the '+' operator
+
+The condition checkers are boolean (true/false) checkers. Machine code is generated
+for the checker itself and for the actions depending on the result of the checker.
+The 'true' case is called as the matching path (expected path), and the other is called as
+the 'backtrack' path. Branch instructions are expesive for all CPUs, so we avoid taken
+branches on the matching path.
+
+ Greedy star operator (*) :
+   Matching path: match happens.
+   Backtrack path: match failed.
+ Non-greedy star operator (*?) :
+   Matching path: no need to perform a match.
+   Backtrack path: match is required.
+
+The following example shows how the code generated for a capturing bracket
+with two alternatives. Let A, B, C, D are arbirary regular expressions, and
+we have the following regular expression:
+
+   A(B|C)D
+
+The generated code will be the following:
+
+ A matching path
+ '(' matching path (pushing arguments to the stack)
+ B matching path
+ ')' matching path (pushing arguments to the stack)
+ D matching path
+ return with successful match
+
+ D backtrack path
+ ')' backtrack path (If we arrived from "C" jump to the backtrack of "C")
+ B backtrack path
+ C expected path
+ jump to D matching path
+ C backtrack path
+ A backtrack path
+
+ Notice, that the order of backtrack code paths are the opposite of the fast
+ code paths. In this way the topmost value on the stack is always belong
+ to the current backtrack code path. The backtrack path must check
+ whether there is a next alternative. If so, it needs to jump back to
+ the matching path eventually. Otherwise it needs to clear out its own stack
+ frame and continue the execution on the backtrack code paths.
+*/
+
+/*
+Saved stack frames:
+
+Atomic blocks and asserts require reloading the values of private data
+when the backtrack mechanism performed. Because of OP_RECURSE, the data
+are not necessarly known in compile time, thus we need a dynamic restore
+mechanism.
+
+The stack frames are stored in a chain list, and have the following format:
+([ capturing bracket offset ][ start value ][ end value ])+ ... [ 0 ] [ previous head ]
+
+Thus we can restore the private data to a particular point in the stack.

+                   "Recursion" in the match() function
+
+The original match() function was highly recursive, but this proved to be the
+source of a number of problems over the years, mostly because of the relatively
+small system stacks that are commonly found. As new features were added to
+patterns, various kludges were invented to reduce the amount of stack used,
+making the code hard to understand in places.
+
+A version did exist that used individual frames on the heap instead of calling
+match() recursively, but this ran substantially slower. The current version is
+a refactoring that uses a vector of frames to remember backtracking points.
+This runs no slower, and possibly even a bit faster than the original recursive
+implementation.
+
+At first, an initial vector of size START_FRAMES_SIZE (enough for maybe 50
+frames) was allocated on the system stack. If this was not big enough, the heap
+was used for a larger vector. However, it turns out that there are environments
+where taking as little as 20KiB from the system stack is an embarrassment.
+After another refactoring, the heap is used exclusively, but a pointer the
+frames vector and its size are cached in the match_data block, so that there is
+no new memory allocation if the same match_data block is used for multiple
+matches (unless the frames vector has to be extended).

+(i.e. something has been matched, even if not part of the actual matched

+property selects a bit from that word like this:
+
+  PRIV(ucp_gbtable)[left-property] & (1u << right-property)
+
+The value is non-zero if a grapheme break is NOT permitted between the relevant
+two code points. The breaking rules are as follows:
+
+1. Break at the start and end of text (pretty obviously).
+
+2. Do not break between a CR and LF; otherwise, break before and after
+   controls.
+
+3. Do not break Hangul syllable sequences, the rules for which are:
+
+    L may be followed by L, V, LV or LVT
+    LV or V may be followed by V or T
+    LVT or T may be followed by T
+
+4. Do not break before extending characters or zero-width-joiner (ZWJ).
+
+The following rules are only for extended grapheme clusters (but that's what we
+are implementing).
+
+5. Do not break before SpacingMarks.
+
+6. Do not break after Prepend characters.
+
+7. Do not break within emoji modifier sequences or emoji zwj sequences. That
+   is, do not break between characters with the Extended_Pictographic property
+   if a ZWJ intervenes. Extend characters are allowed between the characters;
+   this cannot be represented in this table, the code has to deal with it.
+
+8. Do not break within emoji flag sequences. That is, do not break between
+   regional indicator (RI) symbols if there are an odd number of RI characters
+   before the break point. This table encodes "join RI characters"; the code
+   has to deal with checking for previous adjoining RIs.
+
+9. Otherwise, break everywhere.

+/*************************************************
+*           PCRE2 DEMONSTRATION PROGRAM          *
+*************************************************/
+
+/* This is a demonstration program to illustrate a straightforward way of
+using the PCRE2 regular expression library from a C program. See the
+pcre2sample documentation for a short discussion ("man pcre2sample" if you have
+the PCRE2 man pages installed). PCRE2 is a revised API for the library, and is
+incompatible with the original PCRE API.
+
+There are actually three libraries, each supporting a different code unit
+width. This demonstration program uses the 8-bit library. The default is to
+process each code unit as a separate character, but if the pattern begins with
+"(*UTF)", both it and the subject are treated as UTF-8 strings, where
+characters may occupy multiple code units.
+
+In Unix-like environments, if PCRE2 is installed in your standard system
+libraries, you should be able to compile this program using this command:
+
+cc -Wall pcre2demo.c -lpcre2-8 -o pcre2demo
+
+If PCRE2 is not installed in a standard place, it is likely to be installed
+with support for the pkg-config mechanism. If you have pkg-config, you can
+compile this program using this command:
+
+cc -Wall pcre2demo.c `pkg-config --cflags --libs libpcre2-8` -o pcre2demo
+
+If you do not have pkg-config, you may have to use something like this:
+
+cc -Wall pcre2demo.c -I/usr/local/include -L/usr/local/lib \
+  -R/usr/local/lib -lpcre2-8 -o pcre2demo
+
+Replace "/usr/local/include" and "/usr/local/lib" with wherever the include and
+library files for PCRE2 are installed on your system. Only some operating
+systems (Solaris is one) use the -R option.
+
+Building under Windows:
+
+If you want to statically link this program against a non-dll .a file, you must
+define PCRE2_STATIC before including pcre2.h, so in this environment, uncomment
+the following line. */
+
+/* #define PCRE2_STATIC */
+
+/* The PCRE2_CODE_UNIT_WIDTH macro must be defined before including pcre2.h.
+For a program that uses only one code unit width, setting it to 8, 16, or 32
+makes it possible to use generic function names such as pcre2_compile(). Note
+that just changing 8 to 16 (for example) is not sufficient to convert this
+program to process 16-bit characters. Even in a fully 16-bit environment, where
+string-handling functions such as strcmp() and printf() work with 16-bit
+characters, the code for handling the table of named substrings will still need
+to be modified. */

+* If the "-g" option was given on the command line, we want to continue  *
+* to search for additional matches in the subject string, in a similar   *
+* way to the /g option in Perl. This turns out to be trickier than you   *
+* might think because of the possibility of matching an empty string.    *
+* What happens is as follows:                                            *
+*                                                                        *
+* If the previous match was NOT for an empty string, we can just start   *
+* the next match at the end of the previous one.                         *
+*                                                                        *
+* If the previous match WAS for an empty string, we can't do that, as it *
+* would lead to an infinite loop. Instead, a call of pcre2_match() is    *
+* made with the PCRE2_NOTEMPTY_ATSTART and PCRE2_ANCHORED flags set. The *
+* first of these tells PCRE2 that an empty string at the start of the    *
+* subject is not a valid match; other possibilities must be tried. The   *
+* second flag restricts PCRE2 to one match attempt at the initial string *
+* position. If this match succeeds, an alternative to the empty string   *
+* match has been found, and we can print it and proceed round the loop,  *
+* advancing by the length of whatever was found. If this match does not  *
+* succeed, we still stay in the loop, advancing by just one character.   *
+* In UTF-8 mode, which can be set by (*UTF) in the pattern, this may be  *
+* more than one byte.                                                    *
+*                                                                        *
+* However, there is a complication concerned with newlines. When the     *
+* newline convention is such that CRLF is a valid newline, we must       *
+* advance by two characters rather than one. The newline convention can  *
+* be set in the regex by (*CR), etc.; if not, we must find the default.  *

+/* This is a grep program that uses the 8-bit PCRE regular expression library
+via the PCRE2 updated API to do its pattern matching. On Unix-like, Windows,
+and native z/OS systems it can recurse into directories, and in z/OS it can
+handle PDS files.
+
+Note that for native z/OS, in addition to defining the NATIVE_ZOS macro, an
+additional header is required. That header is not included in the main PCRE2
+distribution because other apparatus is needed to compile pcre2grep for z/OS.
+The header can be found in the special z/OS distribution, which is available
+from www.zaconsultants.net or from www.cbttape.org.

+
+Any substring (including the program name) can contain escape sequences
+started by the dollar character. The escape sequences are substituted as

+  decimal number, which must be greater than zero. If the number is greater
+  than the number of capturing substrings, or if the capture is unset, the
+  replacement is empty.
+
+  Any other character is substituted by itself. E.g: $$ is replaced by a single

+
+Alternatively, if string starts with pipe, the remainder is taken as an output
+string, same as --output. This is the only form that is supported if

+This program tests the POSIX wrapper to the PCRE2 regular expression library.
+The main PCRE2 test program is pcre2test, which also tests these function
+calls. This little program is needed to test the case where the client includes
+pcre2posix.h but not pcre2.h, mainly to make sure that it builds successfully.
+However, the code is written as a flexible test program to which extra tests
+can be added.
+
+Compile with -lpcre2-posix -lpcre2-8
+
+If run with no options, there is no output on success, and the return code is
+zero. If any test fails there is output to stderr, and the return code is 1.
+
+For testing purposes, the "-v" option causes verification output to be written
+to stdout. */

+/* PCRE2 is a library of functions to support regular expressions whose syntax
+and semantics are as close as possible to those of the Perl 5 language. In 2014
+the API was completely revised and '2' was added to the name, because the old
+API, which had lasted for 16 years, could not accommodate new requirements. At
+the same time, this testing program was re-designed because its original
+hacked-up (non-) design had also run out of steam.

+/* This program supports testing of the 8-bit, 16-bit, and 32-bit PCRE2
+libraries in a single program, though its input and output are always 8-bit.
+It is different from modules such as pcre2_compile.c in the library itself,
+which are compiled separately for each code unit width. If two widths are
+enabled, for example, pcre2_compile.c is compiled twice. In contrast,
+pcre2test.c is compiled only once, and linked with all the enabled libraries.
+Therefore, it must not make use of any of the macros from pcre2.h or
+pcre2_internal.h that depend on PCRE2_CODE_UNIT_WIDTH. It does, however, make
+use of SUPPORT_PCRE2_8, SUPPORT_PCRE2_16, and SUPPORT_PCRE2_32, to ensure that

+/*
+   This file contains a simple executable memory allocator
+
+   It is assumed, that executable code blocks are usually medium (or sometimes
+   large) memory blocks, and the allocator is not too frequently called (less
+   optimized than other allocators). Thus, using it as a generic allocator is
+   not suggested.
+
+   How does it work:
+     Memory is allocated in continuous memory areas called chunks by alloc_chunk()
+     Chunk format:
+     [ block ][ block ] ... [ block ][ block terminator ]
+
+   All blocks and the block terminator is started with block_header. The block
+   header contains the size of the previous and the next block. These sizes
+   can also contain special values.
+     Block size:
+       0 - The block is a free_block, with a different size member.
+       1 - The block is a block terminator.
+       n - The block is used at the moment, and the value contains its size.
+     Previous block size:
+       0 - This is the first block of the memory chunk.
+       n - The size of the previous block.
+
+   Using these size values we can go forward or backward on the block chain.
+   The unused blocks are stored in a chain list pointed by free_blocks. This
+   list is useful if we need to find a suitable memory area when the allocator
+   is called.
+
+   When a block is freed, the new free block is connected to its adjacent free
+   blocks if possible.
+
+     [ free block ][ used block ][ free block ]
+   and "used block" is freed, the three blocks are connected together:
+     [           one big free block           ]
+*/
+
+/* Expected functions:
+     alloc_chunk / free_chunk :
+       * allocate executable system memory chunks
+       * the size is always divisible by CHUNK_SIZE
+     SLJIT_ALLOCATOR_LOCK / SLJIT_ALLOCATOR_UNLOCK :
+       * provided as part of sljitUtils

+   This file contains a simple W^X executable memory allocator
+
+   In *NIX, MAP_ANON is required (that is considered a feature) so make
+   sure to set the right availability macros for your system or the code
+   will fail to build.
+
+   If your system doesn't support mapping of anonymous pages (ex: IRIX) it
+   is also likely that it doesn't need this allocator and should be using
+   the standard one instead.
+
+   It allocates a separate map for each code block and may waste a lot of
+   memory, because whatever was requested, will be rounded up to the page
+   size (minimum 4KB, but could be even bigger).
+
+   It changes the page permissions (RW <-> RX) as needed and therefore, if you
+   will be updating the code after it has been generated, need to make sure to
+   block any concurrent execution, or could result in a SIGBUS, that could
+   even manifest itself at a different address than the one that was being
+   modified.
+
+   Only use if you are unable to use the regular allocator because of security
+   restrictions and adding exceptions to your application or the system are
+   not possible.

+   This file contains a simple W^X executable memory allocator
+
+   In *NIX, MAP_ANON is required (that is considered a feature) so make
+   sure to set the right availability macros for your system or the code
+   will fail to build.
+
+   If your system doesn't support mapping of anonymous pages (ex: IRIX) it
+   is also likely that it doesn't need this allocator and should be using
+   the standard one instead.
+
+   It allocates a separate map for each code block and may waste a lot of
+   memory, because whatever was requested, will be rounded up to the page
+   size (minimum 4KB, but could be even bigger).
+
+   It changes the page permissions (RW <-> RX) as needed and therefore, if you
+   will be updating the code after it has been generated, need to make sure to
+   block any concurrent execution, or could result in a SIGBUS, that could
+   even manifest itself at a different address than the one that was being
+   modified.
+
+   Only use if you are unable to use the regular allocator because of security
+   restrictions and adding exceptions to your application or the system are
+   not possible.

+   ------------------------------------------------------------------------
+    Stack-Less JIT compiler for multiple architectures (x86, ARM, PowerPC)
+   ------------------------------------------------------------------------
+
+   Short description
+    Advantages:
+      - The execution can be continued from any LIR instruction. In other
+        words, it is possible to jump to any label from anywhere, even from
+        a code fragment, which is compiled later, as long as the compiling
+        context is the same. See sljit_emit_enter for more details.
+      - Supports self modifying code: target of any jump and call
+        instructions and some constant values can be dynamically modified
+        during runtime. See SLJIT_REWRITABLE_JUMP.
+        - although it is not suggested to do it frequently
+        - can be used for inline caching: save an important value once
+          in the instruction stream
+      - A fixed stack space can be allocated for local variables
+      - The compiler is thread-safe
+      - The compiler is highly configurable through preprocessor macros.
+        You can disable unneeded features (multithreading in single
+        threaded applications), and you can use your own system functions
+        (including memory allocators). See sljitConfig.h.
+    Disadvantages:
+      - The compiler is more like a platform independent assembler, so
+        there is no built-in variable management. Registers and stack must
+        be managed manually (the name of the compiler refers to this).
+    In practice:
+      - This approach is very effective for interpreters
+        - One of the saved registers typically points to a stack interface
+        - It can jump to any exception handler anytime (even if it belongs
+          to another function)
+        - Hot paths can be modified during runtime reflecting the changes
+          of the fastest execution path of the dynamic language
+        - SLJIT supports complex memory addressing modes
+        - mainly position and context independent code (except some cases)
+
+    For valgrind users:
+      - pass --smc-check=all argument to valgrind, since JIT is a "self-modifying code"

+  Scratch (R) registers: registers which may not preserve their values
+  across function calls.
+
+  Saved (S) registers: registers which preserve their values across
+  function calls.
+
+  The scratch and saved register sets overlap. The last scratch register
+  is the first saved register, the one before the last is the second saved
+  register, and so on.
+
+  For example, in an architecture with only five registers (A-E), if two
+  are scratch and three saved registers, they will be defined as follows:
+
+    A |   R0   |      |  R0 always represent scratch register A
+    B |   R1   |      |  R1 always represent scratch register B
+    C |  [R2]  |  S2  |  R2 and S2 represent the same physical register C
+    D |  [R3]  |  S1  |  R3 and S1 represent the same physical register D
+    E |  [R4]  |  S0  |  R4 and S0 represent the same physical register E
+
+  Note: SLJIT_NUMBER_OF_SCRATCH_REGISTERS will be 2 and
+        SLJIT_NUMBER_OF_SAVED_REGISTERS will be 3.
+
+  Note: For all supported architectures SLJIT_NUMBER_OF_REGISTERS >= 12
+        and SLJIT_NUMBER_OF_SAVED_REGISTERS >= 6. However, 6 registers
+        are virtual on x86-32. See below.
+
+  The purpose of this definition is convenience: saved registers can
+  be used as extra scratch registers. For example, building in the
+  previous example, four registers can be specified as scratch registers
+  and the fifth one as saved register, allowing any user code which requires
+  four scratch registers to run unmodified. The SLJIT compiler automatically
+  saves the content of the two extra scratch register on the stack. Scratch
+  registers can also be preserved by saving their value on the stack but
+  that needs to be done manually.
+
+  Note: To emphasize that registers assigned to R2-R4 are saved
+        registers, they are enclosed by square brackets.
+
+  Note: sljit_emit_enter and sljit_set_context define whether a register
+        is S or R register. E.g: if in the previous example 3 scratches and
+        1 saved are mapped by sljit_emit_enter, the allowed register set
+        will be: R0-R2 and S0. Although S2 is mapped to the same register
+        than R2, it is not available in that configuration. Furthermore
+        the S1 register cannot be used at all.

+
+/* The following argument type definitions are used by sljit_emit_enter,
+   sljit_set_context, sljit_emit_call, and sljit_emit_icall functions.
+
+   For sljit_emit_call and sljit_emit_icall, the first integer argument
+   must be placed into SLJIT_R0, the second one into SLJIT_R1, and so on.
+   Similarly the first floating point argument must be placed into SLJIT_FR0,
+   the second one into SLJIT_FR1, and so on.
+
+   For sljit_emit_enter, the integer arguments can be stored in scratch
+   or saved registers. Scratch registers are identified by a _R suffix.
+
+   If only saved registers are used, then the allocation mirrors what is
+   done for the "call" functions but using saved registers, meaning that
+   the first integer argument goes to SLJIT_S0, the second one goes into
+   SLJIT_S1, and so on.
+
+   If scratch registers are used, then the way the integer registers are
+   allocated changes so that SLJIT_S0, SLJIT_S1, etc; will be assigned
+   only for the arguments not using scratch registers, while SLJIT_R
+   will be used for the ones using scratch registers.
+
+   Furthermore, the index (shown as "n" above) that will be used for the
+   scratch register depends on how many previous integer registers
+   (scratch or saved) were used already, starting with SLJIT_R0.
+   Eventhough some indexes will be likely skipped, they still need to be
+   accounted for in the scratches parameter of sljit_emit_enter. See below
+   for some examples.
+
+   The floating point arguments always use scratch registers (but not the
+   _R suffix like the integer arguments) and must use SLJIT_FR0, SLJIT_FR1,
+   just like in the "call" functions.
+
+   Note: the mapping for scratch registers is part of the compiler context
+         and therefore a new context after sljit_emit_call/sljit_emit_icall
+         could remove access to some scratch registers that were used as
+         arguments.
+
+   Example function definition:
+     sljit_f32 SLJIT_FUNC example_c_callback(void *arg_a,
+         sljit_f64 arg_b, sljit_u32 arg_c, sljit_f32 arg_d);
+
+   Argument type definition:
+     SLJIT_ARG_RETURN(SLJIT_ARG_TYPE_F32)
+        | SLJIT_ARG_VALUE(SLJIT_ARG_TYPE_P, 1) | SLJIT_ARG_VALUE(SLJIT_ARG_TYPE_F64, 2)
+        | SLJIT_ARG_VALUE(SLJIT_ARG_TYPE_32, 3) | SLJIT_ARG_VALUE(SLJIT_ARG_TYPE_F32, 4)
+
+   Short form of argument type definition:
+     SLJIT_ARGS4(F32, P, F64, 32, F32)
+
+   Argument passing:
+     arg_a must be placed in SLJIT_R0
+     arg_b must be placed in SLJIT_FR0
+     arg_c must be placed in SLJIT_R1
+     arg_d must be placed in SLJIT_FR1
+
+   Examples for argument processing by sljit_emit_enter:
+     SLJIT_ARGS4V(P, 32_R, F32, W)
+     Arguments are placed into: SLJIT_S0, SLJIT_R1, SLJIT_FR0, SLJIT_S1
+     The type of the result is void.
+
+     SLJIT_ARGS4(F32, W, W_R, W, W_R)
+     Arguments are placed into: SLJIT_S0, SLJIT_R1, SLJIT_S1, SLJIT_R3
+     The type of the result is sljit_f32.
+
+     SLJIT_ARGS4(P, W, F32, P_R)
+     Arguments are placed into: SLJIT_FR0, SLJIT_S0, SLJIT_FR1, SLJIT_R1
+     The type of the result is pointer.
+
+     Note: it is recommended to pass the scratch arguments first
+     followed by the saved arguments:
+
+       SLJIT_ARGS4(W, W_R, W_R, W, W)
+       Arguments are placed into: SLJIT_R0, SLJIT_R1, SLJIT_S0, SLJIT_S1

+   (SLJIT_ARGS0 .. SLJIT_ARGS4) macros. Currently maximum four
+   arguments are supported. See the description of SLJIT_ARGSx
+   macros about argument passing. Furthermore the register set

+   and "scratches" argument can be used later. E.g. if "scratches"

+   SLJIT_R0 and SLJIT_R1. The S registers and the floating point
+   registers ("fscratches" and "fsaveds") are specified in a
+   similar manner. The sljit_emit_enter is also capable of
+   allocating a stack space for local data. The "local_size"
+   argument contains the size in bytes of this local area, and
+   it can be accessed using SLJIT_MEM1(SLJIT_SP). The memory
+   area between SLJIT_SP (inclusive) and SLJIT_SP + local_size
+   (exclusive) can be modified freely until the function returns.
+   The stack space is not initialized to zero.

+/* Sets 32 bit operation mode on 64 bit CPUs. This option is ignored on

+   the lower 32 bits of the input registers are used, and the CPU status
+   flags are set according to the 32 bit result. Although the higher 32 bit
+   of the input and the result registers are not defined by SLJIT, it might
+   be defined by the CPU architecture (e.g. MIPS). To satisfy these CPU
+   requirements all source registers must be the result of those operations
+   where this option was also set. Memory loads read 32 bit values rather
+   than 64 bit ones. In other words 32 bit and 64 bit operations cannot be
+   mixed. The only exception is SLJIT_MOV32 which source register can hold
+   any 32 or 64 bit value, and it is converted to a 32 bit compatible format
+   first. When the source and destination registers are the same, this
+   conversion is free (no instructions are emitted) on most CPUs. A 32 bit
+   value can also be converted to a 64 bit value by SLJIT_MOV_S32
+   (sign extension) or SLJIT_MOV_U32 (zero extension).
+
+   As for floating-point operations, this option sets 32 bit single
+   precision mode. Similar to the integer operations, all register arguments
+   must be the result of those operations where this option was also set.
+
+   Note: memory addressing always uses 64 bit values on 64 bit systems so
+         the result of a 32 bit operation must not be used with SLJIT_MEMx
+         macros.
+
+   This option is part of the instruction name, so there is no need to
+   manually set it. E.g:
+
+     SLJIT_ADD32 == (SLJIT_ADD | SLJIT_32) */

+
+/* Many CPUs (x86, ARM, PPC) have status flag bits which can be set according
+   to the result of an operation. Other CPUs (MIPS) do not have status
+   flag bits, and results must be stored in registers. To cover both
+   architecture types efficiently only two flags are defined by SLJIT:
+
+    * Zero (equal) flag: it is set if the result is zero
+    * Variable flag: its value is defined by the arithmetic operation
+
+   SLJIT instructions can set any or both of these flags. The value of
+   these flags is undefined if the instruction does not specify their
+   value. The description of each instruction contains the list of
+   allowed flag types.
+
+   Note: the logical or operation can be used to set flags.
+
+   Example: SLJIT_ADD can set the Z, OVERFLOW, CARRY flags hence
+
+     sljit_op2(..., SLJIT_ADD, ...)
+       Both the zero and variable flags are undefined so they can
+       have any value after the operation is completed.
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_Z, ...)
+       Sets the zero flag if the result is zero, clears it otherwise.
+       The variable flag is undefined.
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_OVERFLOW, ...)
+       Sets the variable flag if an integer overflow occurs, clears
+       it otherwise. The zero flag is undefined.
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_Z | SLJIT_SET_CARRY, ...)
+       Sets the zero flag if the result is zero, clears it otherwise.
+       Sets the variable flag if unsigned overflow (carry) occurs,
+       clears it otherwise.
+
+   Certain instructions (e.g. SLJIT_MOV) does not modify flags, so
+   status flags are unchanged.
+
+   Example:
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_Z, ...)
+     sljit_op1(..., SLJIT_MOV, ...)
+       Zero flag is set according to the result of SLJIT_ADD.
+
+     sljit_op2(..., SLJIT_ADD | SLJIT_SET_Z, ...)
+     sljit_op2(..., SLJIT_ADD, ...)
+       Zero flag has unknown value.
+
+   These flags can be used for code optimization. E.g. a fast loop can be
+   implemented by decreasing a counter register and set the zero flag
+   using a single instruction. The zero register can be used by a
+   conditional jump to restart the loop. A single comparison can set a
+   zero and less flags to check if a value is less, equal, or greater
+   than another value.
+
+   Motivation: although some CPUs can set a large number of flag bits,
+   usually their values are ignored or only a few of them are used. Emulating
+   a large number of flags on systems without a flag register is complicated
+   so SLJIT instructions must specify the flag they want to use and only
+   that flag is computed. The last arithmetic instruction can be repeated if
+   multiple flags need to be checked.

+Rd is the destination register operand, while Rj, Rk and Ra (“a” stands for “additional”) are the source register operands.
+I8/I12/I14/I16/I21/I26 are immediate operands of respective width. The longer I21 and I26 are stored in separate higher and
+lower parts in the instruction word, denoted by the “L” and “H” suffixes. */

+This is a file of miscellaneous text that is used as test data for checking
+that the pcregrep command is working correctly. The file must be more than
+24KiB long so that it needs more than a single read() call to process it. New
+features should be added at the end, because some of the tests involve the
+output of line numbers, and we don't want these to change.
+
+PATTERN at the start of a line.
+In the middle of a line, PATTERN appears.
+
+This pattern is in lower case.
+
+Here follows a whole lot of stuff that makes the file over 24KiB long.

+# This is a specialized test for checking, when PCRE2 is compiled with the
+# EBCDIC option but in an ASCII environment, that newline, white space, and \c
+# functionality is working. It catches cases where explicit values such as 0x0a
+# have been used instead of names like CHAR_LF. Needless to say, it is not a
+# genuine EBCDIC test! In patterns, alphabetic characters that follow a
+# backslash must be in EBCDIC code. In data, NL, NEL, LF, ESC, and DEL must be
+# in EBCDIC, but can of course be specified as escapes.

+systems.
+
+In environments that support the GNU autotools, config.h.in is converted into
+config.h by the "configure" script. In environments that use CMake,
+config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
+hand" without using "configure" or CMake, you should copy the distributed
+config.h.generic to config.h, and edit the macro definitions to be the way you
+need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
+so that config.h is included at the start of every source.
+
+Alternatively, you can avoid editing by using -D on the compiler command line
+to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
+but if you do, default values will be taken from config.h for non-boolean
+macros that are not defined on the command line.
+
+Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be
+defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All
+such macros are listed as a commented #undef in config.h.generic. Macros such
+as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
+surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
