Flake Inputs

• nixpkgs (nixos-unstable)
• home-manager (master)
• nix-darwin
• nix-homebrew
• nixos-wsl
• zen-browser

The Nix implementation used is Lix.

Initial Install

Prerequisites

Install Nix with flakes support. The Determinate Systems installer is recommended as it enables flakes by default.

nix-darwin (macOS)

git clone https://github.com/Marfien/dotfiles.git ~/.dotfiles
cd ~/.dotfiles
nix run nix-darwin -- switch --flake .#mac

After the initial build, use darwin-rebuild directly:

darwin-rebuild switch --flake ~/.dotfiles#mac

NixOS (WSL)

1. Install NixOS-WSL following their instructions.
2. Clone and apply the configuration:

git clone https://github.com/Marfien/dotfiles.git ~/.dotfiles
cd ~/.dotfiles
sudo nixos-rebuild switch --flake .#wsl-soptim

Home-Manager (standalone)

If you only want the home-manager configuration without a full system rebuild:

git clone https://github.com/Marfien/dotfiles.git ~/.dotfiles
cd ~/.dotfiles
nix run home-manager -- switch --flake .#<username>

Note: Standalone home-manager configurations are not currently exported by this flake. Use the full system commands above.

How to Upgrade

Update all flake inputs to their latest versions and rebuild:

cd ~/.dotfiles
nix flake update

Then apply the updated configuration:

# macOS
darwin-rebuild switch --flake ~/.dotfiles#mac

# NixOS / WSL
sudo nixos-rebuild switch --flake ~/.dotfiles#wsl-soptim

To update a single input:

nix flake update home-manager
