Create git commit template according to commit convention

[repparw]

see here for logic

Can create something like that (or below) as .gitmessage and set commit.template in git config, so wen using git commit we get a default template hinting/guiding with commit convention

File location can be changed too.

Template doesn't affect directly passed messages (e.g -m "message")

#«scope»: «summary»

#«motivation for change»

# «scope» can be one of:
#   ci: Changes to GitHub Actions workflows.
#   doc: Changes to the website, README.md, and so on.
#   stylix: Changes in the `stylix` directory, flake.nix, and other global code.
#   Name of target: Changes to code for a particular target.
#   treewide: Changes across many targets.
#
# «summary» should start with a lowercase letter, and should not end with punctuation.

Sounds neat, although I have never seen any project automatically customize .git/ beyond "trivial" pre-commit hooks. I assume the nix develop nature justifies such .git/ modifications. Maybe it would be better to try upstreaming this to https://github.com/cachix/git-hooks.nix and pulling this functionality on our end. Upstreaming this, hopefully helps people beyond just Stylix.

I don't think it's in scope of git hooks? I mean, you could just commit -m and nothing would stop you. it's more a guidance, easier to skip than a pre-commit hook.
either way the template would change according to the convention of each repo, but if upstream thinks they'd like it it would be okay

Searching a little bit more, something like this should be done on a custom .gitconfig, in the repo root.
As modifying .git wouldn't be pushed to the repo
An example I found, it doesn't do much in this case https://github.com/socketstream/socketstream/blob/develop/.gitconfig

Exactly. The nix develop command could ensure that .git/config is properly setup. This is the logic that I meant to be potentially upstreamed to https://github.com/cachix/git-hooks.nix.
