Usage

Below is a minimal flake.nix to get started. See example.nix for an example firewalld configuration.

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    firewalld-nix = {
      url = "sourcehut:~prince213/firewalld-nix";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs =
    { nixpkgs, firewalld-nix, ... }:
    {
      nixosConfigurations.system = nixpkgs.lib.nixosSystem {
        modules = [
          firewalld-nix.nixosModules.default
          {
            services.firewalld.enable = true;

            # pick one
            services.firewalld.package = firewalld-nix.packages.x86_64-linux.firewalld;
            nixpkgs.overlays = [ firewalld-nix.overlays.default ];
          }
        ];
      };
    };
}
