Nix Installation

Install Lix on macOS or Ubuntu using a single command:

curl -sSf -L https://install.lix.systems/lix | sh -s -- install

This will install a complete Lix setup on your system.

Building and Switching

macOS (darwin)

Build macOS configuration

Build the darwin configuration without applying it:

nix build .#mac

Or using darwin-rebuild:

darwin-rebuild build --flake '.#mac'

Switch to macOS configuration

Apply the configuration to your system (requires sudo for system activation):

sudo nix --extra-experimental-features "nix-command flakes" run nix-darwin -- switch --flake '.#mac'

Or if darwin-rebuild is available in your PATH:

darwin-rebuild switch --flake '.#mac'

Linux (NixOS)

Build Linux configuration

Build the NixOS configuration without applying it:

nix build .#nixosConfigurations.linux.config.system.build.toplevel

Or using nixos-rebuild:

sudo nixos-rebuild build --flake '.#linux'

Switch to Linux configuration

Apply the configuration to your system:

sudo nixos-rebuild switch --flake '.#linux'

Configuration

Shared Configuration

The following modules are shared between both platforms:

• Packages: neovim, tmux
• Fonts: Fira Code, JetBrains Mono, Droid Sans Mono
• Nix Settings: Flakes enabled, experimental features

macOS-Specific

• Homebrew management via nix-homebrew
• Spotlight integration for nix-installed applications
• PATH priority to ensure nix packages take precedence
• macOS-specific packages: alacritty, obsidian, mkalias

Linux-Specific

• NixOS system configuration
• Linux-specific packages (add as needed)

Notes

• The quotes around '.#mac' or '.#linux' are required in zsh to prevent glob expansion
• The --extra-experimental-features flag must be passed to nix before run when using nix run
• All module files must be git-tracked for nix flakes to include them
