+\r
+Very fast, header only, C++ logging library. [](https://travis-ci.org/gabime/spdlog) [](https://ci.appveyor.com/project/gabime/spdlog)\r
+\r
+\r
+\r
+## Install\r
+#### Just copy the headers:\r
+\r
+* Copy the source [folder](https://github.com/gabime/spdlog/tree/v1.x/include/spdlog) to your build tree and use a C++11 compiler.\r
+\r
+#### Or use your favorite package manager:\r
+\r
+* Ubuntu: `apt-get install libspdlog-dev`\r
+* Homebrew: `brew install spdlog`\r
+* FreeBSD: `cd /usr/ports/devel/spdlog/ && make install clean`\r
+* Fedora: `yum install spdlog`\r
+* Gentoo: `emerge dev-libs/spdlog`\r
+* Arch Linux: `yaourt -S spdlog-git`\r
+* vcpkg: `vcpkg install spdlog`\r
+ \r
+\r
+## Platforms\r
+ * Linux, FreeBSD, OpenBSD, Solaris, AIX\r
+ * Windows (msvc 2013+, cygwin)\r
+ * macOS (clang 3.5+)\r
+ * Android\r
+\r
+## Features\r
+* Very fast (see [benchmarks](#benchmarks) below).\r
+* Headers only, just copy and use.\r
+* Feature rich formatting, using the excellent [fmt](https://github.com/fmtlib/fmt) library.\r
+* Fast asynchronous mode (optional)\r
+* [Custom](https://github.com/gabime/spdlog/wiki/3.-Custom-formatting) formatting.\r
+* Multi/Single threaded loggers.\r
+* Various log targets:\r
+ * Rotating log files.\r
+ * Daily log files.\r
+ * Console logging (colors supported).\r
+ * syslog.\r
+ * Windows debugger (```OutputDebugString(..)```)\r
+ * Easily extendable with custom log targets (just implement a single function in the [sink](include/spdlog/sinks/sink.h) interface).\r
+* Severity based filtering - threshold levels can be modified in runtime as well as in compile time.\r
+* Binary data logging.\r
+\r
+\r

+## Usage samples\r
+\r
+#### Basic usage\r
+```c++\r
+#include "spdlog/spdlog.h"\r
+int main() \r
+{\r
+ spdlog::info("Welcome to spdlog!");\r
+ spdlog::error("Some error message with arg: {}", 1);\r
+ \r
+ spdlog::warn("Easy padding in numbers like {:08d}", 12);\r
+ spdlog::critical("Support for int: {0:d}; hex: {0:x}; oct: {0:o}; bin: {0:b}", 42);\r
+ spdlog::info("Support for floats {:03.2f}", 1.23456);\r
+ spdlog::info("Positional args are {1} {0}..", "too", "supported");\r
+ spdlog::info("{:<30}", "left aligned");\r
+ \r
+ spdlog::set_level(spdlog::level::debug); // Set global log level to debug\r
+ spdlog::debug("This message should be displayed.."); \r
+ \r
+ // change log pattern\r
+ spdlog::set_pattern("[%H:%M:%S %z] [%n] [%^---%L---%$] [thread %t] %v");\r
+ \r
+ // Compile time log levels\r
+ // define SPDLOG_ACTIVE_LEVEL to desired level\r
+ SPDLOG_TRACE("Some trace message with param {}", {});\r
+ SPDLOG_DEBUG("Some debug message");\r
+ \r
+}\r
+```\r
+#### create stdout/stderr logger object\r
+```c++\r
+#include "spdlog/spdlog.h"\r
+#include "spdlog/sinks/stdout_color_sinks.h"\r
+void stdout_example()\r
+{\r
+ // create color multi threaded logger\r
+ auto console = spdlog::stdout_color_mt("console"); \r
+ auto err_logger = spdlog::stderr_color_mt("stderr"); \r
+ spdlog::get("console")->info("loggers can be retrieved from a global registry using the spdlog::get(logger_name)");\r
+}\r
+```\r
+---\r
+#### Basic file logger\r
+```c++\r
+#include "spdlog/sinks/basic_file_sink.h"\r
+void basic_logfile_example()\r
+{\r
+ try \r
+ {\r
+ auto my_logger = spdlog::basic_logger_mt("basic_logger", "logs/basic-log.txt");\r
+ }\r
+ catch (const spdlog::spdlog_ex &ex)\r
+ {\r
+ std::cout << "Log init failed: " << ex.what() << std::endl;\r
+ }\r
+}\r
+```\r
+---\r
+#### Rotating files\r
+```c++\r
+#include "spdlog/sinks/rotating_file_sink.h"\r
+void rotating_example()\r
+{\r
+ // Create a file rotating logger with 5mb size max and 3 rotated files\r
+ auto rotating_logger = spdlog::rotating_logger_mt("some_logger_name", "logs/rotating.txt", 1048576 * 5, 3);\r
+}\r
+```\r
+\r
+---\r
+#### Daily files\r
+```c++\r
+\r
+#include "spdlog/sinks/daily_file_sink.h"\r
+void daily_example()\r
+{\r
+ // Create a daily logger - a new file is created every day on 2:30am\r
+ auto daily_logger = spdlog::daily_logger_mt("daily_logger", "logs/daily.txt", 2, 30);\r
+}\r
+\r
+```\r
+\r
+---\r
+#### Cloning loggers \r
+```c++\r
+// clone a logger and give it new name.\r
+// Useful for creating subsystem loggers from some "root" logger\r
+void clone_example()\r
+{\r
+ auto network_logger = spdlog::get("root")->clone("network");\r
+ network_logger->info("Logging network stuff..");\r
+}\r
+```\r
+\r
+---\r
+#### Periodic flush\r
+```c++\r
+// periodically flush all *registered* loggers every 3 seconds:\r
+// warning: only use if all your loggers are thread safe!\r
+spdlog::flush_every(std::chrono::seconds(3));\r
+\r
+```\r
+\r
+---\r
+#### Binary logging\r
+```c++\r
+// log binary data as hex.\r
+// many types of std::container<char> types can be used.\r
+// ranges are supported too.\r
+// format flags:\r
+// {:X} - print in uppercase.\r
+// {:s} - don't separate each byte with space.\r
+// {:p} - don't print the position on each line start.\r
+// {:n} - don't split the output to lines.\r
+\r
+#include "spdlog/fmt/bin_to_hex.h"\r
+\r
+void binary_example()\r
+{\r
+ auto console = spdlog::get("console");\r
+ std::array<char, 80> buf;\r
+ console->info("Binary example: {}", spdlog::to_hex(buf));\r
+ console->info("Another binary example:{:n}", spdlog::to_hex(std::begin(buf), std::begin(buf) + 10));\r
+ // more examples:\r
+ // logger->info("uppercase: {:X}", spdlog::to_hex(buf));\r
+ // logger->info("uppercase, no delimiters: {:Xs}", spdlog::to_hex(buf));\r
+ // logger->info("uppercase, no delimiters, no position info: {:Xsp}", spdlog::to_hex(buf));\r
+}\r
+\r
+```\r
+\r
+---\r
+#### Logger with multi sinks - each with different format and log level\r
+```c++\r
+\r
+// create logger with 2 targets with different log levels and formats.\r
+// the console will show only warnings or errors, while the file will log all.\r
