1 month ago That's very similar to what I've done in pre-commit, https://flake.parts/options/pre-commit-hooks-nix#opt-perSystem.pre-commit.pkgs
In that one, the pre-commit-hooks modules are loaded into a sub-option settings, which you don't have here, which I think is good, and that's the only real difference.
We could call it a pattern. :+1:
I believe @shivaraj-bh added this because treefmt-nix requires a newer nixpkgs, so for projects that still use older nixpkgs, we could solve that by explicitly passing a
pkgs-latestto treefmt-nix.cc @roberth (this may be a general thing with all flake-parts modules?)
