get_git_root_path should support worktrees

[madig]

Git supports the concept of multiple working directories connected to different branches of the same repo: https://git-scm.com/docs/git-worktree.

get_git_root_path currently fails to handle it properly and raises OSError: Unable to determine git repository root for font file ....

how do you use this approach in your workflows Nikolaus?

[chrissimpkins]

It looks like this is config'd via the .git dir in the main directory from which the worktree branches are derived? Wondering if this means that there is a more general / global config approach?

Seems like .git in a worktree is a file with the pointer to the main repo. You can extract the path with https://gitpython.readthedocs.io/en/stable/reference.html?highlight=worktree#git.repo.fun.find_worktree_git_dir from that file. You still have to fiddle with the path though, as it points to somewhere inside the main .git dir.
