My ZSH setup as a flake and nix-shell

flake.nix

{
  outputs = { self, ... }: {
    homeManagerModules.zsh = import ./zsh.nix;
  };
}

zsh.nix

{ config, pkgs, ... }:

      # Modern replacements
      ls = "eza";
      ll = "eza -l";
      la = "eza -la";
      tree = "eza --tree";

  # Install required packages
  home.packages = with pkgs; [
