From 5caa25e269d97acd37543a697151ecb816327451 Mon Sep 17 00:00:00 2001 From: John Scott Date: Wed, 1 Mar 2023 11:58:09 +0100 Subject: [PATCH] work around unset SAGE_ROOT in Debian Sage package Bug-Debian: https://bugs.debian.org/972346 Forwarded: https://bugs.kde.org/show_bug.cgi?id=408176#c19 Last-Update: 2021-01-17 In this shell script, '$1' refers to the Sage binary that is to be used. The script is needlessly complex to accommodate for old versions of Sage, and perhaps the author is unaware of Sage's new command-line arguments. Debian's `sage --root` is an empty string, so Cantor fails to start it. This patch is more succinct by starting the Sage shell which sets all variables appropriately, then starting 'sage-ipython' as desired. This way, as opposed to having '#!/usr/bin/sage --sh' as the shebang, still permits usage of local Sage copies.
