In reply to @gavinrogers:matrix.org
ok i got a working flake.nix in my /etc/nixos but when i put in the example in the README i get an error

{
  inputs = {
    home-manager.url = "github:nix-community/home-manager";
    nix-doom-emacs.url = "github:nix-community/nix-doom-emacs";
  };
  outputs = {
    self,
    nixpkgs,
    home-manager,
    nix-doom-emacs,
    ...
  }:
 {
    nixosConfigurations.nixos = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        home-manager.nixosModules.home-manager
        ({
          home-manager.users.chran = nixpkgs.lib.mkMerge [
            nix-doom-emacs.hmModule
              {
              programs.doom-emacs = {
                enable = true;
                doomPrivateDir = ./doom.d;
              };
            }
          ];
        })
      ./configuration.nix

    };

Well, hello again! I'm starting to have some time again which is why I'm prograrmming some hobby projects lately, mainly using Idris 2, and I thought to boot up Doom Emacs (i don't yet have enough free time to start working on the documentation PR again unfortrunately, though i see you're making some progress, though somewhat slow. keep going!). For whatever reason, the pictured error below appears when running idris2-mode. But... I do depend on prop-menu in my configuration:

doom-emacs = {
  enable = true;
  doomPrivateDir = ./doom;
  extraPackages = \[ pkgs.mu ];
  emacsPackage = pkgs.emacsPgtkNativeComp;
  emacsPackagesOverlay = self: super: {
    idris2-mode = self.trivialBuild {
      pname = "idris2-mode";
      ename = "idris2-mode";
      version = "0.0.0";
      buildInputs = \[ self.prop-menu ];
      src = pkgs.fetchFromGitHub {
        owner = "idris-community";
        repo = "idris2-mode";
        rev = "4a3f9cdb1a155da59824e39f0ac78ccf72f2ca97";
        sha256 = "sha256-TxsGaG2fBRWWP9aas59kiNnUVD4ZdNlwwaFbM4+n81c=";
      };
    };
  };
};

any idea what's going wrong?
