Nix Config

This repository contains my nix configurations (for nixOS, macOS, linux and wsl). Nix home-manager is used across all systems to manage my dotfiles and user specific applications. Nix darwin is used to manage my macOS machines.

Installation

MacOS

1. Install Nix:

   sh <(curl -L https://nixos.org/nix/install) 

2. Clone repo and create a custom config

   Clone this repository to your home directory:

   cd ~/.config && git clone https://github.com/CemDK/nix.git && cd nix

   In the flake.nix file add your hostname and username to the darwinConfigurations attribute set. For example, if your username is CoolGuyUser and your hostname is 2010-Macbook, you would add:

   darwinConfigurations = {
     "CoolGuyUser@2010-macbook" = mkDarwinConfig {
       system = "x86_64-darwin"; # or "aarch64-darwin" for M1/M2/M3/M4 Macs
       user = "CoolGuyUser";
       host = "2010-macbook";
       userHost = "CoolGuyUser@2010-macbook";
       home = "/Users/CoolGuyUser";
     };
     # ... other macOS configurations
   };

   Create a new file: /users/CoolGuyUser/home.nix

   { pkgs, user, home, ... }:
   
   # A minimal config might look like this:
   {
     # Import modules that you want to use
     # default.nix is my own bespoke custom made artisinal handcrafted setup
     # so beware that it already contains my configuration for zsh, tmux, zoxide, etc.
     imports = [
       ../../modules/home-manager/default.nix
     ];
   
     home = {
       username = user;
       homeDirectory = home;
     };
   
     # You can manage dotfiles here 
     home.file = { };
   
     # Add packages that are specific to this user here
     home.packages = with pkgs;
       [
         neovim
         go
       ];
   }

3. Run nix-darwin Rebuild:

   Finally, to install nix-darwin and apply your configuration, run the following command:

   sudo nix run nix-darwin/master#darwin-rebuild -- switch --flake ~/.config/nix/.#$(whoami)@$(hostname -I)

   Afterwards, if you include the aliases from my zsh config, you can run these aliased commands nixup, nixswitch and nixclean or the default sudo darwin-rebuild switch --flake ~/.config/nix/.#$(whoami)@$(hostname -I).
