Conventional Commits pre-commit check is not working

[srid]

The second commit in PR #127 has the commit message use same installer - yet the pre-commit check did not catch it, as it doesn't comfort to conventional commits spec.

[srid]

Commit's vanished because I had to force push, but the commit message was literally use same installer.

The hook itself works,

However, if I skip it:

And run the flake check:

... it passes ^

[srid]

I don't think the pre-commit module actually adds a flake check.

Also, https://github.com/convco/convco

We can run this manually

[terlar]

Yeah, when running in a flake check it won't have access to .git/COMMIT_EDITMSG and will therefore not be able to check the commit message. The workaround is to use nix run nixpkgs#pre-commit directly on CI. That is what I found as well, although I was using conform.

[srid]

A PR can have multiple commits, so whatever flake check we add must check all of them.

[srid]

But since git history will be available, perhaps it should be run outside of Nix, in github actions.

This command checks for all the commits on the current branch, starting from main:

cz check --rev-range main..HEAD

[srid]

Cool. We should also consider #134 when deciding between cz and convco.

cz check --rev-range main..HEAD

Can’t do this until NixOS/nix#6900

I have made some progress at https://github.com/juspay/services-flake/tree/cz-check, will wait until there is a reliable way to copy .git to the store.

[srid]

Copying .git to the Nix store sounds like a bad idea in general? We only need history of commit messages, not the whole index (much less copy a variation of it every time to the store).

I doubt we can pass this to flake check in a straightforward way.

One hack to make this work will be to use writeShellApplication and run cz check --rev-range main..HEAD via nix run.
