A general purpose tool to set up good feedback loops and share them with your team.

Use the feedback command to set up a feedback loop for your work.

For example, if you are working on a nix build, you might use this feedback loop:

feedback -- nix-build

Usually feedback will correctly figure out which files to watch and which files not to watch, but you can also configure this more precisely.

You can declare feedback loops in the feedback.yaml configuration file to share them with your team. For example, this gives you a flake-based feedback loop:

loops:
  check: nix flake check -L

Then you can just run this command, and not have to remember the full incantation:

feedback check

To see the full reference of options of the configuration file, run feedback --help.

When sharing feedback loops with team members, it is important that no one breaks another's workflow. You can use feedback-test to test out the feedback loops in a one-shot manner, so you can check that they still work on CI. See feedback-test --help for more details.

nix run github:NorfairKing/feedback

Add this to your system flake:

{
  inputs = {
    feedback.url = "github:NorfairKing/feedback?ref=flake";
  };
  outputs = { nixpkgs, feedback, ... }:
    let system = "x86_64-linux";
    in {
      nixosConfigurations.example = nixpkgs.lib.nixosSystem {
        inherit system;
        modules = [
          { environment.systemPackages = [ feedback.packages.${system}.default ]; }
        ];
      };
    };
}
