@mdarocha It seems to work now, I would honestly move the shell declaration into a shell.nix file and use that, also I would use Cachix in order to shorten the package fetch times

The following commits 1dc3f57eb5bdb3e30d68ab919a7399b162dd384e, 3033512ea06dc15d14db0a9d6385a09a11790bb8, and fed4efd0c94f336bea2fb4e24fd4e1fa1bf47936 were added in order to verify that the CI indeed passes when no diffs are found, will be dropped later.
Please do not merge it without dropping those commits, as I'd rather not have all of those linted codelines on me only since I was the one who ran treefmt last, especially since I'm not maintainer.

P.S. the commits in which the formatting will be done can be ignored in git blame: https://akrabat.com/ignoring-revisions-with-git-blame/

So this will create commits, if someone forgets to run treefmt? Or will it reject pushes and pull requests?

The validations in the CI will fail and a merge would not be allowed

Looks good! However, I'd prefer using flakes and nix run instead of nix-shell, so that the nixpkgs version defined in flake.lock is used.

Thanks!
For sure, I'm just a Nix noob, so I didn't try doing it by myself

I'll archive this repository now. I created an Issue in the new repository to not forget this pull request. terranix/terranix.github.io#10 < please comment in this issue in the future.
