Add Nix Component

How to add a new feature module, host, overlay, package, or NixOS user to this flake. Use when creating any new file under modules/, hosts/, or packages/.

File contents

  1. New feature module: drop modules/{nixos,darwin,home}-modules/<name>.nix wrapped in { ... }: { flake.<class>Modules.<name> = <NixOS module>; }. import-tree picks it up; nothing else to wire.
  2. New host: add the host file(s) under hosts/{nixos,darwin,home/<user>}/ and add a small mkNixos/mkDarwin/mkHome entry to modules/wiring/hosts.nix (system + hostPath, plus sharedPath for HM). System architecture is declared per host (no more hostToSystem heuristic — be explicit).
  3. New overlay: drop modules/overlays/<name>.nix exporting flake.overlays.<name> = final: prev: { ... }.
  4. New package: place the callPackage derivation at packages/<name>.nix and register it via modules/packages/<name>.nix:
    { ... }:
{
  perSystem = { pkgs, ... }: {
    packages.<name> = pkgs.callPackage ../../packages/<name>.nix { };
  };
}
  5. NixOS users: modules/nixos-modules/users-<user>.nix is one self-contained module per user. Enable on a host via modules.users.<user>.enable = true;.
