NixOS or Home Manager

As Rong is very experimental, this hasn't been added to nixpkgs. You have create a custom package.

I'm currently working on creating modules for NixOS and Home Manager. For now, you can use this following package snippet to create an overlay.

If you know how to create NixOS modules, consider contributing to the GitHub repository.

  lib,
  buildGoModule,
  installShellFiles,
  fetchFromGitHub,
  stdenv,
}:
buildGoModule {
  pname = "rong";
  version = "0-unstable-2025-07-27";

  src = fetchFromGitHub {
    owner = "Nadim147c";

  };

  vendorHash = "sha256-gT5iAYcUif2PQO6lVJRfUjddeAJc5ZrHg5hmkLkZeME=";

  ldflags = ["-s" "-w"];

  nativeBuildInputs = [installShellFiles];

    installShellCompletion --cmd $out/bin/rong \
        --bash <(echo "$bashComp") \
        --fish <(echo "$fishComp") \
        --zsh <(echo "$zshComp")
  '';

  meta = {
    description = "A Material You color generator";
    homepage = "https://github.com/Nadim147c/rong";
    license = lib.licenses.gpl3Only;
    mainProgram = "rong";
  };
}

Update the hash and revision to latest commit for up-to-date features.
