NixOS Configurations for My Machines

This repository contains NixOS configurations for my machines, managed through Nix Flakes.

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

Showcase

Hyprland

Gnome

Structure

• flake.nix: The flake itself, defining inputs (such as nixpkgs, home-manager, and hardware-specific optimizations) and outputs for NixOS and Home Manager configurations.
• hosts/: NixOS 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.

Key Inputs

• nixpkgs: Points to the nixos-24.05 channel, providing stable NixOS packages.
• nixpkgs-unstable: Points to the nixos-unstable channel for access to the latest 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.

User Configuration

The flake now includes a users attribute set, defining user-specific information:

users = {
  jdoe = {
    email = "joe.doe@example.com";
    fullName = "Joe Doe";
    gitKey = "A0000000";
    name = "jdoe";
  };
};

This configuration is passed to both NixOS and Home Manager configurations, allowing for consistent user settings across the system.

Usage

Building and Applying NixOS Configurations

To apply a configuration to a specific system, run:

nixos-rebuild switch --flake .#<hostname>

Replace <hostname> with the name of the target machine, e.g., energy or nabokikh-z13.

Managing Home Configuration

Home Manager is used to manage user configurations independently of system configurations. To apply a user configuration, use:

home-manager switch --flake .#<user>@<hostname>

Updating Flakes

To update all flake inputs to their latest versions:

nix flake update

Custom Modules and Configurations

This setup includes various custom modules and configurations:

• Desktop Environments: Supports both Hyprland and GNOME.
• Development Tools: Includes configurations for Neovim, Git, Go, and more.
• System Tools: Configures utilities like Alacritty, Atuin, Bottom, and FZF.
• Audio: Includes EasyEffects for audio enhancement.
• Gaming: Supports Steam and Lutris for gaming on NixOS.
• AI/ML: Includes Ollama for local AI model running.
