Support for submodules

[piotrb]

When running lefthook on a checked out submodule the directory structure is not as expected.

$ lefthook install
SYNCING lefthook.yml
SERVED HOOKS: pre-commit, prepare-commit-msg
open {HOME}/{PROJECT}/{SUBMODULE_NAME}/.git/hooks/pre-commit: not a directory

This is because in a submodule .git is a file with the following content:

gitdir: ../.git/modules/{SUBMODULE_NAME}

It sounds simple enough to have lefthook understand that and just follow that relative path instead and drop the hooks there.

(I did a quick test, that's all that's needed, if you drop the hooks in that folder instead it seems to work as expected)

Thank you for issue @piotrb!
Unfortunately, I'm a little busy in the coming days :(
If you have the opportunity to do PR with a correction, this will be great. I will accept it and release with your fix.

Hi I have one issue with my project structure.
And I'm not sure is it in scope of this enhancement or not.

I'm trying to migrate JavaScript project from Husky. It has following folder structure:

/ my_project_parent
  / .git
  / my_project
       lefthook.yml
       package.json
       ...
...

The problem is that lefthook looking for .git folder in my_project at the moment, while it is actually in parent folder.

It would be nice if it can find parent .git and write hooks there.

Yea, just need to replace calls form getRootDir() to result of that call: git rev-parse --show-toplevel.
In that case GIR_DIR env variable should be supported too.
