Your first Module

Configuring a code machine means configuring a NixOS module. Don't worry, if you've never done this, it is really simple: In your project's git repository, create a file called configuration.nix with the following content:

{ pkgs, ... }: { environment.systemPackages = [ pkgs.neofetch ]; time.timeZone = "Europe/Berlin"; # Time is UTC by default }

For Codchi to be able to pick it up, you also need to create a flake.nix in the root directory of your repository:

{ description = "My awesome code machine"; outputs = { ... }: { nixosModules.myModule = ./configuration.nix; }; }

Make sure that the path to configuration.nix is correct. It must start with ./! Now push both files to a code forge of your choice and create a code machine:

codchi init myMachine https://github.com/my/repo nixosModules.myModule

Notice that nixosModules.myModule is from flake.nix, so make sure they match! Now build the machine and run neofetch:

codchi rebuild myMachine codchi exec myMachine neofetch ▗▄▄▄ ▗▄▄▄▄ ▄▄▄▖ codchi@nixos ▜███▙ ▜███▙ ▟███▛ ------------ ▜███▙ ▜███▙▟███▛ OS: NixOS x86_64 ▜███▙ ▜██████▛ Host: ... ▟█████████████████▙ ▜████▛ ▟▙ Kernel: 6.1.64 ▟███████████████████▙ ▜███▙ ▟██▙ Uptime: ... ▄▄▄▄▖ ▜███▙ ▟███▛ Packages: 383 (nix-system) ▟███▛ ▜██▛ ▟███▛ Shell: bash 5.2.15 ▟███▛ ▜▛ ▟███▛ Resolution: 1920x1080 ▟███████████▛ ▟██████████▙ CPU: ... ▜██████████▛ ▟███████████▛ GPU: ... ▟███▛ ▟▙ ▟███▛ GPU: ... ▟███▛ ▟██▙ ▟███▛ Memory: 19MiB / ... ▟███▛ ▜███▙ ▝▀▀▀▀ ▜██▛ ▜███▙ ▜██████████████████▛ ▜▛ ▟████▙ ▜████████████████▛ ▟██████▙ ▜███▙ ▟███▛▜███▙ ▜███▙ ▟███▛ ▜███▙ ▜███▙ ▝▀▀▀ ▀▀▀▀▘ ▀▀▀▘
