Flake Module

flakeModules.default exposes every keyboard in this repo as packages in the importing flake. It requires an input named zmk-config:

# flake.nix
{
  inputs.zmk-config.url = "github:semi710/zmk-config";

  outputs = inputs:
    inputs.nix-wire.mkFlake { inherit inputs; } {
      imports = [ inputs.zmk-config.flakeModules.default ];
    };
}

What you get

Package	Contents
zmk	default keyboard firmware (zmk_left.uf2 + zmk_right.uf2)
zmk-flash	interactive flash helper for the default keyboard (Linux)
zmk-<name>	firmware for keyboard <name>
zmk-flash-<name>	flash helper for keyboard <name> (Linux)

The default keyboard is default in keyboards.nix.

nix build .#zmk           # default keyboard
nix build .#zmk-corne     # explicit
nix run .#zmk-flash       # flash on a Linux host with the keyboard mounted

Adding a keyboard

1. keyboards/<name>/ with west.yml (self.path: <name>), <name>.conf, <name>.keymap, and optional patches/
2. Register it in keyboards.nix:

keyboards = {
  corne = { ... };
  sofle = {
    board = "nice_nano_v2";
    shield = "sofle_%PART% nice_oled";
    zephyrDepsHash = "sha256-...";
    # patches = [ "keyboards/sofle/patches/*.patch" ];
  };
};

1. Run nix build .#sofle, paste the got: hash from the mismatch error
2. Add the keyboard to the CI matrix in .github/workflows/build.yml

Consumers get packages.zmk-sofle on the next input bump - no changes needed in the importing flake.
