Installing using Nix

Nix users can install Hunk from source instead of using npm.

Install from a flake

1. Add Hunk to your nix flake inputs like such:

{
    inputs = {
        hunk = {
          url = "github:modem-dev/hunk";
          inputs.nixpkgs.follows = "nixpkgs";
        };
    }
}

2. Use in NixOS environment.systemPackages:

{
  environment.systemPackages = [
    inputs.hunk.packages.${pkgs.stdenv.hostPlatform.system}.hunk
  ];
}

Or in Home Manager home.packages:

{
  home.packages = [
    inputs.hunk.packages.${pkgs.stdenv.hostPlatform.system}.hunk
  ];
}

Home Manager

Hunk provides a Home Manager module to manage both the package and its configuration.

1. Add the module to your Home Manager configuration:

{
  imports = [
    inputs.hunk.homeManagerModules.default
  ];

  programs.hunk = {
    enable = true;
    enableGitIntegration = true; # Optional: set hunk as default git pager
    settings = {
      theme = "graphite";
      mode = "split";
      line_numbers = true;
    };
  };
}

enableGitIntegration writes to Home Manager's Git configuration, so it requires Home Manager's Git module to be enabled with programs.git.enable = true;.

Running from a flake

Run Hunk directly with Nix:

nix run github:modem-dev/hunk -- --help

Updating Hunk

Flake users update Hunk by updating their own pinned flake.lock input:

nix flake lock --update-input hunk

Building using Nix

Run nix build to build the default package for the current system. The resulting Hunk binary will be ./result/bin/hunk.

You can also build the named package explicitly:

nix build .#hunk

Maintainer dependency updates

When JavaScript or Bun dependencies change, regenerate the Nix dependency lockfile and commit it with the dependency change:

bun run nix:update-lock

This script requires Nix and runs the flake-pinned bun2nix version from flake.lock.
