This repository contains NixOS and nix-darwin configurations for my machines, managed through Nix Flakes.

It is structured to easily accommodate multiple machines and user configurations, leveraging nixpkgs, home-manager, nix-darwin, and various other community contributions for a seamless experience across NixOS and macOS.

• flake.nix: The flake itself, defining inputs and outputs for NixOS, nix-darwin, and Home Manager configurations.
• hosts/: NixOS and nix-darwin configurations for each machine, including system-specific settings.
• home/: Home Manager configurations for user-specific settings and applications.
• files/: Miscellaneous configuration files and scripts used across various applications and services.
• flake.lock: Lock file ensuring reproducible builds by pinning input versions.
• overlays/: Custom Nix overlays for package modifications or additions.

• nixpkgs: Points to the nixos-unstable channel for access to the latest packages.
• nixpkgs-stable: Points to the nixos-24.05 channel, providing stable NixOS packages.
• home-manager: Manages user-specific configurations, following the nixpkgs input (release-24.05).
• hardware: Optimizes settings for different hardware configurations.
• catppuccin: Provides global Catppuccin theme integration.
• spicetify-nix: Enhances Spotify client customization.
• darwin: Enables nix-darwin for macOS system configuration.
• nix-homebrew: Integrates Homebrew package management with nix-darwin.

To add a new machine with a new user to your NixOS or nix-darwin configuration, follow these steps:

1. Update flake.nix:

   a. Add the new user to the users attribute set:

   users = {
     # Existing users...
     newuser = {
       email = "newuser@example.com";
       fullName = "New User";
       gitKey = "YOUR_GIT_KEY";
       name = "newuser";
     };
   };

   b. Add the new machine to the appropriate configuration set:

   For NixOS:

   nixosConfigurations = {
     # Existing configurations...
     newmachine = mkNixosConfiguration "newmachine" "newuser";
   };

   For nix-darwin:

   darwinConfigurations = {
     # Existing configurations...
     newmachine = mkDarwinConfiguration "newmachine" "newuser";
   };

   c. Add the new home configuration:

   homeConfigurations = {
     # Existing configurations...
     "newuser@newmachine" = mkHomeConfiguration "x86_64-linux" "newuser" "newmachine";
   };

2. Create System Configuration:

   a. Create a new directory under hosts/ for your machine:

   mkdir -p hosts/newmachine

   b. Create configuration.nix in this directory:

   touch hosts/newmachine/configuration.nix

   c. Add the basic configuration to configuration.nix:

   For NixOS:

   { config, pkgs, ... }:
   
   {
     imports = [
       ./hardware-configuration.nix
       ../modules/common.nix
       # Add other relevant modules
     ];
   
     # Add machine-specific configurations here
   }

   For nix-darwin:

   { config, pkgs, ... }:
   
   {
     imports = [
       ../modules/common.nix
       # Add other relevant modules
     ];
   
     # Add machine-specific configurations here
   }

   d. For NixOS, generate hardware-configuration.nix:

   sudo nixos-generate-config --show-hardware-config > hosts/newmachine/hardware-configuration.nix

3. Create Home Manager Configuration:

   a. Create a new file for the user's home configuration:

   mkdir -p home/newuser
   touch home/newuser/newmachine.nix

   b. Add basic home configuration:

   { config, pkgs, ... }:
   
   {
     imports = [
       ../modules/common.nix
       # Add other relevant modules
     ];
   
     # Add user-specific configurations here
   }

4. Building and Applying Configurations:

   a. Do not forget to check-in new files in git by running git add .

   b. Build and switch to the new system configuration:

   For NixOS:

   sudo nixos-rebuild switch --flake .#newmachine

   For nix-darwin:

   darwin-rebuild switch --flake .#newmachine

   c. Build and switch to the new Home Manager configuration:

   home-manager switch --flake .#newuser@newmachine

To update all flake inputs to their latest versions:

nix flake update

For example, to enable Alacritty and Neovim in your home configuration:

{ config, pkgs, ... }:

{
  imports = [
    ./modules/alacritty.nix
    ./modules/neovim.nix
    # Other modules...
  ];

  # Additional configurations...
}
