Subject: [git-gui] bug report: "Open existing repository" dialog fails on submodules
Message-ID: <CAMto89Dvz-u+at4CPLGQRak4niOJk1trSCn2wQugLUnD1h=Fjw@mail.gmail.com>

Hi,

This bug report concerns git-gui. Apologies if this is not the right
mailing-list.

By submodule I mean a repository for which .git is not a regular Git
directory, but rather a "gitdir: ..." file.
While running "git gui" from such a directory will work fine, trying
to open it from the choose_repository window will fail with "Not a Git
repository". This is because of the simplistic implementation of proc
_is_git in lib/choose_repository.tcl.

I suggest fixing that function, or using Git directly to perform that
check, for instance checking "git rev-parse --show-toplevel". I'd
attempt a patch but my tcl-fu is weak.

Best
