treefmt settings do not include config or configPath

[JayRovacsek]

Currently the treefmt hook does not support a configuration path option that would enable the reference of treefmt.toml. Without running treefmt --init or --config-file the check cannot be utilised in a consistent way if the config file is not committed to the repository

Happy to contribute a PR that adds this if deemed suitable 🙏

The flake-parts module has a special integration that activates when you load both git-hooks.nix and treefmt-nix. Might that help?

It's defined here:

git-hooks.nix/flake-module.nix

Line 72 in 40e6053

hooks.treefmt.package = lib.mkIf (options?treefmt) (lib.mkOverride 900 config.treefmt.build.wrapper);

Thanks for the fast response @roberth, unfortunately I don't utilise flake-parts myself (though I might be misunderstanding how I'd consume the flakeModule code)

Would the project be open to a PR that added a setting for config/configFile akin to the implementation for typos? (ref)
