NixOS Configuration

My personal NixOS configuration featuring:

• Flakes for reproducible builds
• Home Manager integration
• Modular structure with separate NixOS and Home Manager components
• Catppuccin theming (Macchiato Lavender variant)

Installation

Option 1: Clean Install (Wipes existing configuration)

sudo rm -rf /etc/nixos
sudo git clone https://github.com/win-hafus/nixos-config /etc/nixos
# Edit configuration files:
#   - Set username in hosts/<your-host>.nix
#   - Configure options in modules/nixos/core.nix
sudo nixos-rebuild switch --flake /etc/nixos#hfv5

Option 2: Integrate with Existing Configuration

1. Clone the repository:

git clone https://github.com/win-hafus/nixos-config

2. Import desired modules into your configuration
3. Ensure all inputs are declared in your flake.nix

Flake Inputs

{
  inputs = {
    nixpkgs.url = "nixpkgs/nixos-unstable";
    catppuccin.url = "github:catppuccin/nix";
    minegrub-world-sel-theme.url = "github:Lxtharia/minegrub-world-sel-theme";
    spicetify-nix.url = "github:Gerg-L/spicetify-nix";
    zen-browser = {
      url = "github:0xc000022070/zen-browser-flake";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    home-manager = {
      url = "github:nix-community/home-manager";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs =
    {
      self,
      nixpkgs,
      home-manager,
      minegrub-world-sel-theme,
      catppuccin,
      zen-browser,
      spicetify-nix,
    }@inputs:
    {
      nixosConfigurations.nixos = nixpkgs.lib.nixosSystem {
        system = "x86_64-linux";
        specialArgs = { inherit inputs; };
        modules = [
          ./hosts/default/configuration.nix
          catppuccin.nixosModules.catppuccin
          home-manager.nixosModules.home-manager
          minegrub-world-sel-theme.nixosModules.default
          spicetify-nix.nixosModules.default
          {
            home-manager.extraSpecialArgs = { inherit inputs; };
            home-manager.users.hfv5 = {
              imports = [
                ./hosts/default/home.nix
                catppuccin.homeModules.catppuccin
                spicetify-nix.homeManagerModules.default
              ];
            };
          }
        ];
      };
    };
}

Features

• Automatic Home Manager build from system configuration
• Shared packages between NixOS and Home Manager
• ${username} variables for easy customization
• Catppuccin theming for:
  • GTK applications
  • SDDM login manager
  • Terminal tools (via catppuccin-nix)
• Dual desktop environment support:
  • Default: Hyprland

Notes

1. Replace all instances of ${username} with your actual username
2. Wallpapers are managed through SWWW - configure in home.nix
