Integrate with pre-commit framework

[TribuneX]

Feature Request

Summary

We heavily automate our git related tooling with pre-commit. Wouldn't this be a good fit for git-sumi as well?

Motivation

pre-commit is a widely used framework for commit hooks. It also makes it easy to discover new hooks (given the project meets certain requirements).

Detailed Description

Implementing a pre-commit hook is straight forward.

Additional Context

I could also provide a PR if thats a desired feature.

Hi Sascha!

I've seen pre-commit used in many projects, so I think it would make sense to integrate git-sumi with it!

I'd definitely take a PR for this. I can help with documentation or any questions/issues. Let me know!

[TribuneX]

Great. I'll take a look and will provide an PR for this. I do not have experience with rust / cargo yet. But thats solvable 😃.

[welpo]

Great! Do not hesitate to reach out for help!!

I started looking into this. It looks like pre-commit does not pass the commit message but a file which may contain the commit message, which makes sense, since the commit message can span multiple lines:

prepare-commit-msg hooks will be passed a single filename -- this file may be empty or it could contain the commit message from -m or from other templates. prepare-commit-msg hooks can modify the contents of this file to change what will be committed.

See docs

Seems that git sumi does not have a cli flag yet to cope with this case. Any ideas how to integrate it with pre-commit this way?

Now it does :)

After #198 you can use --file.
