treefmt nix configuration

This repo is for users that use both Nix and treefmt.

It contains a mapping from programs to treefmt.toml formatter entries, maintained by the community.

Quick Usage

This returns a treefmt instance with terraform configured to format *.tf files:

{ nixpkgs, treefmt-nix, ... }:
treefmt-nix.lib.mkWrapper nixpkgs {
  # Used to find the project root
  projectRootFile = ".git/config";
  # Enable the terraform formatter
  programs.terraform.enable = true;
  # Override the default package
  programs.terraform.package = nixpkgs.terraform_1_0;
  # Override the default settings generated by the above option
  settings.formatter.terraform.excludes = ["hello.tf"];
}
