I was aware of the failing formatting check, but that is existing bad formatting and I was loathe to change formatting outside of code I was modifying myself. |

@chris114782 This assumes that the gitdir is a relative path, which might not be true.

I'll try and take a look this weekend, it's been a few months (nearly a year now!) since I looked at this and I need to get my head back into it.

In #200 I highlighted that the library does not support submodules.
This is because in a submodule does not store its .git folder inside the checked out repository, instead .git is a file that has a reference to the actual location of the .git directory.
This is documented here
You can manually reproduce this by doing
git clone --separate-git-dir=/somewhere/else your-repo-urlThis PR adds support for such a set up by detecting that .git is a file instead of a directory and attempting to read the path to the real directory from it.
