From 4f2214a1d6349884135f0485a36e3bfad31350a2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=EB=A7=88=EB=88=84=EC=97=98?= Date: Wed, 17 Jun 2015 09:30:41 +0200 Subject: [PATCH 39/N] path-conversion: Introduce ability to switch off conversion. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When calling windows native apps from MSYS2, the runtime tries to convert commandline arguments by a specific set of rules. This idea was inherited from the MSys/MinGW project (which is now seemingly stale, yet must be credited with championing this useful feature, see MinGW wiki https://web.archive.org/web/20201112005258/http://www.mingw.org/wiki/Posix_path_conversion). If the user does not want that behavior on a big scale, e.g. inside a Bash script, with the changes introduced in this commit, the user can now set the the environment variable `MSYS_NO_PATHCONV` when calling native windows commands. This is a feature that has been introduced in Git for Windows via https://github.com/git-for-windows/msys2-runtime/pull/11 and it predates support for the `MSYS2_ENV_CONV_EXCL` and `MSYS2_ARG_CONV_EXCL` environment variables in the MSYS2 runtime; Many users find the simplicity of `MSYS_NO_PATHCONV` appealing. So let's teach MSYS2 proper this simple trick that still allows using the sophisticated `MSYS2_*_CONV_EXCL` facilities but also offers a convenient catch-all "just don't convert anything" knob.
