Getting Started

Before diving in, ensure that you have Nix installed on your system. If not, you can download and install it from the official Nix website or from the Determinate Systems installer. If running on macOS, you need to have Nix-Darwin installed, as well. You can follow the installation instruction on GitHub.

Clone this repository to your local machine

# New machine without git
nix-shell -p git

# Clone
git clone https://github.com/khaneliman/khanelinix.git
cd khanelinix

# Linux
sudo nixos-rebuild switch --flake .

# MacOS
# First run without nix-darwin:
nix run github:lnl7/nix-darwin#darwin-rebuild -- switch --flake github:khaneliman/khanelinix

darwin-rebuild switch --flake .

 # With nh (Nix Helper)
nh os switch .

# With direnv
flake switch

Features

Here's an overview of what my Nix configuration offers:

• External Dependency Integrations:

  • Khanelivim custom neovim configuration built with nixvim.
  • Access NUR expressions for Firefox addons and other enhancements.
  • Integration with Hyprland and other Wayland compositors.

• macOS Support: Seamlessly configure and manage Nix on macOS using the power of Nix-darwin, also leveraging homebrew for GUI applications.

• Home Manager: Manage your dotfiles, home environment, and user-specific configurations with Home Manager.

• DevShell Support: The flake provides a development shell (devShell) to support maintaining this flake. You can use the devShell for convenient development and maintenance of your Nix environment.

• CI with Cachix: The configuration includes continuous integration (CI) that pushes built artifacts to Cachix. This ensures efficient builds and reduces the need to build dependencies on your local machine.

• Utilize sops-nix: Secret management with sops-nix for secure and encrypted handling of sensitive information.

Customization

My Nix configuration is built using flake-parts, providing a flexible and modular approach to managing your Nix environment. Here's how it works:

• Flake Parts Structure: The configuration uses flake-parts to organize outputs into modular parts, with the main flake definition importing from the flake/ directory for better organization.

• Custom Library: The lib/ directory contains custom library functions and utilities that extend the standard nixpkgs lib, providing additional helpers for system configuration.

• Package Management: The packages/ directory contains custom packages exported by the flake. Each package is built using callPackage and can be used across different system configurations.

• Modular Configurations: The modules/ directory defines reusable NixOS, Darwin, and Home Manager modules. This modular approach allows for consistent configuration across different platforms and systems.

• Overlay System: Custom overlays in the overlays/ directory modify and extend the nixpkgs package set, allowing for package customizations and additions.

• System Configurations: Host-specific configurations are organized in systems/ with separate directories for different architectures (x86_64-linux, aarch64-darwin).

• Home Configurations: User-specific Home Manager configurations in the homes/ directory, organized by user and system architecture.

• Development Environment: A partitioned development environment in flake/dev/ provides development shells, formatting tools, and checks separate from the main flake outputs.

This flake-parts based approach provides excellent modularity and makes it easy to maintain and extend the configuration while keeping related functionality organized.

Exported packages

Run packages directly with:

nix run --extra-experimental-features 'nix-command flakes' github:khaneliman/khanelinix#packageName

Or install from the packages output. For example:

# flake.nix
{
  inputs.khanelinix = {
    url = "github:khaneliman/khanelinix";
    inputs.nixpkgs.follows = "nixpkgs";
  };
}

# configuration.nix
{pkgs, inputs, system, ...}: {
  environment.systemPackages = [
    inputs.khanelinix.packages."${system}".packageName
  ];
}
