gather inspiration from the best flakes

[dminca]

Seen a lot of professionally written flakes, to name a few

• https://git.sr.ht/~afontaine/home/tree
• https://git.sr.ht/~bwolf/dotfiles/tree
• https://github.com/Mic92/dotfiles
• https://github.com/konradmalik/dotfiles - Konrad even enabled some CI/CD within his configuration with GitHub Actions; might help on identify what can we make the CI do for us #2

In addition, if we're to define options within the flake, here's a list of supported types by Nix

• https://github.com/NixOS/nixpkgs/blob/ea24372d132cf854937ef41d0d4091ca0e8f7ee9/lib/types.nix#L224-L1049

Some conversation from the forum of people trying to modularize home-manager configuration

• Is this a good way to modularize home manager home.nix for home/work?

• Conditional Implementation

 {config, pkgs, lib, ...}:
 
 {
   systemd.services = lib.mkIf (config.networking.hostName == "my-server") {
      ircSession = {
        wantedBy = [ "multi-user.target" ]; 
        after = [ "network.target" ];
        description = "Start the irc client of username.";
        serviceConfig = {
          Type = "forking";
          User = "username";
          ExecStart = ''${pkgs.screen}/bin/screen -dmS irc ${pkgs.irssi}/bin/irssi'';         
          ExecStop = ''${pkgs.screen}/bin/screen -S irc -X quit'';
        };
      };
   };
 
   environment.systemPackages = lib.mkIf (config.networking.hostName == "my-server") [ pkgs.screen ];
 
   # ... usual configuration ...
 }

• Module System and Custom Options

# ./foo.nix
{ config, lib, pkgs, ... }:

with lib;

let
  cfg = config.programs.foo;
in {
  options.programs.foo = {
    enable = mkEnableOption "the foo program";

    package = mkOption {
      type = types.package;
      default = pkgs.hello;
      defaultText = literalExpression "pkgs.hello";
      description = "foo package to use.";
    };

    extraConfig = mkOption {
      default = "";
      example = ''
        foo bar
      '';
      type = types.lines;
      description = ''
        Extra settings for foo.
      '';
    };
  };

  config = mkIf cfg.enable {
    home.packages = [ cfg.package ];
    xdg.configFile."foo/foorc" = mkIf (cfg.extraConfig != "") {
      text = ''
        # Generated by Home Manager.

        ${cfg.extraConfig}
      '';
    };
  };
}

• Option definitions are generally straight-forward bindings of values to option names

config = if config.services.httpd.enable then {
  environment.systemPackages = [ ... ];
  ...
} else {};

asked the Discord community for proposals and I've got this
