A flake module to build NixOS, nix-darwin and Home Manager configurations, creating a consistent environment across different devices.

lite-config's Issues

Home modules not installed

Hello again Ye Lite,

I've come up against another issue that seems to stem from Home Manager not being configured out of the box.

I can reproduce this issue with a trivial system zsh module and home git module where I conditionally enable each via a mkEnableOption.

{ config
, lib
, ...
}:
let
  inherit (lib) mkEnableOption mkIf;
  cfg = config.my.system.zsh;
in
{
  options.my.system.zsh = {
    enable = mkEnableOption "zsh";
  };

  config = mkIf cfg.enable {
    programs.zsh.enable = true;
  };
}

{ config
, lib
, ...
}:
let
  inherit (lib) mkEnableOption mkIf;
  cfg = config.my.home.git;
in
{
  options.my.home.git = {
    enable = mkEnableOption "git";
  };

  config = mkIf cfg.enable {
    programs.git.enable = true;
  };
}

I toggle these on in my host configuration and only see the system module taking affect.

{ ... }: {
  my = {
    system = {
      zsh.enable = true;
    };

    home = {
      git.enable = true;
    };
  };
}

I might be missing something; maybe I have more work to do with Home Manager to get modules showing up in the host config?

Incompatiblity with nix-community/emacs-overlay

Hello Lite Ye,

Thank you for open sourcing lite-system. It's exactly what I'm looking for and will DRY up my personal Nix configuration that I plan to open source very soon.

I have unfortunately run into an issue when adding the nix-community/emacs-overlay to my work-in-progress configuration. I've pushed a minimal example to jcf/lite-system-emacs-overlay in case it's helpful.

With nothing more than empty host, home, and system modules, I'm able to produce the following error when checking/building from my flake.nix.

{
  outputs = inputs @ { flake-parts, ... }:
    flake-parts.lib.mkFlake { inherit inputs; } ({ inputs, ... }: {

      ];

        nixpkgs = {

Thank You!

This is exactly the type of tool I was looking for!
There are other "frameworks" to make using nixos/HM easier, but they can have additional complexity and, ironically, more boilerplate nix code.
Or they simply don't look as clean.
Good job!
