Hi all;

This is a bit of a long shot; but I’m having an issue with trying to modularize my config in preparation for a new laptop.

In particular the issue I have is around passing a path through to an import statement for a home-managed user.

In particular I’m getting undefinedVariable hmPath; but it doesn’t seem to be having the same issue when I’m mapping groups and shell; so I can only assume that imports has to be treated differently but I’m at a loss.

Any help on what I’ve misunderstood would be greatly appreciated.

Snippet below

{ pkgs, config, options, lib, home-manager, ... }:

with lib; let
  cfg = config.ltp.home;

  user = types.submodule ({name, ...}: {
    options = {
      doas.enable = mkEnableOption {
        default = false;
        type = types.bool;
      };

      groups = mkOption {
        default = [];
        type = types.listOf string;
      };

      shell = mkOption {
        default = pkgs.bash;
        type = types.package;
      };

      hmPath = mkOption {
        type = types.path;
      };
    };
  });
in
{
  options.ltp.home = {
    users = mkOption {
      description = Attrset of home-manager users;
      default = {};
      type = types.attrsOf user;
    };
  };

  config = mkIf (cfg.users != {}) (mkMerge [
    {
      users.users = let mkUser =
        lib.attrsets.mapAttrs'
        (
          name: value:
          lib.attrsets.nameValuePair
            "${builtins.baseNameOf name}"
            {
              isNormalUser = true;
              extraGroups = "${groups}";
              shell = "${shell}";
            }
        )
        cfg.users;
      in
      mkUser;
      
      home-manager.users = let mkHmUser =
        lib.attrsets.mapAttrs'
        (
          name: value:
          lib.attrsets.nameValuePair
            "${builtins.baseNameOf name}"
            {
              imports = [ "${hmPath}" ];
            }
        )
        cfg.users;
      in
      mkHmUser;
    }
  ]);
}

Edit…

Solved the initial issue I was confusing myself and should’ve been using value.hmPath and equivalent inside the lib functions.

Next issue; I’m having is I can’t seem to pass through the path for the home-manager module for the user that is give to the import statement.

Edit 2…

I didn’t manage to get it working how I was doing it so I’ve changed my approach; to implicitly reference the users home-manager base module based on the folder structure e.g. ./hosts/${hostname}/users/${builtins.baseNameOf name}
