please combine the libs

[saygo-png]

i made 2 custom libs because the one i was using earlier couldnt be made to have config since that only is exposed during module eval, so i had to make another one that exposed. I didnt combine them into one because i was dealing with a stupid sx issue and was sick of it after ~5 hours.

Claude said to do it like this which looks like it would work

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

let
  # Your library functions here
  customLib = {
    mkCustomService = { name }: {
      systemd.services.${name} = {
        description = "Service using ${config.networking.hostName}";
        # ... rest of your service config
      };
    };
    
    mkUserEnv = { username }: {
      users.users.${username} = {
        shell = config.users.defaultShell;
        # ... other user settings
      };
    };
  };
in
# Extend the original lib with your additions
lib.extend (final: prev: customLib)

# flake.nix
{
  description = "System with extended lib";

  outputs = { self, nixpkgs, ... }: {
    nixosConfigurations.myhost = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        # Make the extended lib available to all modules
        ({ lib, config, pkgs, ... }: {
          _module.args.lib = import ./lib {
            inherit (nixpkgs) lib;
            inherit config pkgs;
          };
        })
        
        # Your actual configuration
        ({ lib, ... }: {
          # Now you can use your custom functions directly from lib
          imports = [
            (lib.mkCustomService { name = "myservice"; })
          ];
          
          networking.hostName = "myhost";
        })
      ];
    };
  };
}
