ampcode-nix

An automatically updated Nix package for Amp. The version, artifact URLs, and SHA-256 hashes are read from Amp's official Homebrew tap every hour.

nix run github:darwin67/ampcode-nix

Amp is distributed as an unfree binary, but this flake enables the package for direct use. The wrapped executable disables Amp's self-update check and adds ripgrep to its PATH, matching the nixpkgs package behavior.

{
  inputs.ampcode.url = "github:darwin67/ampcode-nix";

  outputs = { self, nixpkgs, ampcode, ... }: {
    nixosConfigurations.my-host = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        ({ pkgs, ... }: {
          environment.systemPackages = [ ampcode.packages.${pkgs.system}.default ];
        })
      ];
    };
  };
}

Or consume the overlay and use pkgs.amp-cli:

nixpkgs.overlays = [ ampcode.overlays.default ];
nixpkgs.config.allowUnfree = true;
environment.systemPackages = [ pkgs.amp-cli ];

Flake packages are exposed for x86_64-linux, aarch64-linux, and aarch64-darwin. The updater also retains the tap's x86_64-darwin source for overlay consumers using an older nixpkgs that still supports Intel macOS. Current nixpkgs unstable has dropped that platform. The official tap's linux-x64 binary may require AVX2; unlike nixpkgs, the tap does not publish its baseline build in the formula.

The hourly workflow runs update.py, validates and builds the flake, and commits a changed sources.json back to the default branch. Updates can also be run locally:

python3 update.py
nix flake check

The repository's GitHub Actions settings must allow workflows to write to the repository. Branch protection must either permit the GitHub Actions bot to push or be adjusted to use pull requests instead.
