nix: patch nix directly for experimental features
The bash wrapper was causing issues with deploy-rs and the
experimental-features option in the config was causing hercules-ci to
spit out a bunch of junk in the logs. Patching nix with the default
values required for flakes fixes both of these issues.

Packages

Similar to modules, the pkgs directory mirrors the upstream nixpkgs/pkgs, and for the same reason; if you ever want to upstream your package, it's as simple as dropping it into the nixpkgs/pkgs directory.

The only minor difference is that, instead of adding the callPackage call to all-packages.nix, you just add it the the default.nix in this directory, which is defined as a simple overlay.

This overlay is set as the default overlay output attribute for the flake. And all the packages are exported via packages.<system>.<pkg-name>, for all the supported systems listed in the package's meta.platforms attribute.

And, as usual, every package in the overlay is also available to any NixOS host.

Example

pkgs/development/libraries/libinih/default.nix:

{ stdenv, meson, ninja, fetchFromGitHub, ... }:
let version = "r50";
in
stdenv.mkDerivation {
  pname = "libinih";
  inherit version;

  src = fetchFromGitHub {
    owner = "benhoyt";
    repo = "inih";
    rev = "${version}";
    hash = "sha256-GF+TVEysaXJxSBBjMsTr2IQvRKlzdEu3rlPQ88PE3nI=";
  };

  buildInputs = [ meson ninja ];

  mesonFlags = ''
    -Ddefault_library=shared
    -Ddistro_install=true
  '';

  meta = with stdenv.lib; {
    description = "Simple .INI file parser in C";
    homepage = "https://github.com/benhoyt/inih";
    maintainers = [ maintainers.nrdxp ];
    license = licenses.bsd3;
    platforms = platforms.all;
    inherit version;
  };
}

pkgs/default.nix:

final: prev: {
  libinih = prev.callPackage ./development/libraries/libinih { };
}
