Packaging Boxflat

Help
1

Hi there,
I’d like to package the App Boxflat for the use with NixOS. I tried using pkgs.buildPythonPackage but couldn’t get it to work and then tried to copy and adjust the Oversteer package and couldn’t get it to work.

Then with the help of LLMs I got something like this:

{
  lib,
  stdenv,
  fetchFromGitHub,
  python3,
  gtk4,
  libadwaita,
  cairo,
  gobject-introspection,
  pkg-config,
  wrapGAppsHook4,
  pkexec ? null,
  makeWrapper,
  graphene,
  glib,
  pango,
  gdk-pixbuf,
}:
let
  version = "v1.25.2";
  pythonEnv = python3.withPackages (
    ps: with ps; [
      pyyaml
      psutil
      pyserial
      pycairo
      pygobject3
      evdev
    ]
  );
in
stdenv.mkDerivation {
  inherit version;
  pname = "boxflat";
  src = fetchFromGitHub {
    owner = "lawstorant";
    repo = "boxflat";
    rev = version;
    sha256 = "sha256-EB4Q8BeTZTmjfA+LRUUHdTBxoH+RpOroZZFmsbDk49U=";
  };
  nativeBuildInputs = [
    pkg-config
    wrapGAppsHook4
    gobject-introspection
    makeWrapper
    pythonEnv
  ];
  buildInputs = [
    gtk4
    libadwaita
    cairo
    glib
    graphene
    pango
    gdk-pixbuf
  ];
  installPhase = ''
    # Create necessary directories
    mkdir -p $out/bin
    mkdir -p $out/lib/python${pythonEnv.pythonVersion}/site-packages/boxflat
    mkdir -p $out/share/boxflat/data
    mkdir -p $out/lib/udev/rules.d

    # Copy all project files to site-packages
    cp -r ./* $out/lib/python${pythonEnv.pythonVersion}/site-packages/boxflat/

    # Install the data folder to the correct location
    cp -r data/* $out/share/boxflat/data/

    # Install udev rules
    cp udev/99-boxflat.rules $out/lib/udev/rules.d/99-boxflat.rules

    # Create wrapper script
    makeWrapper ${pythonEnv}/bin/python $out/bin/boxflat \
      --set PYTHONPATH "$out/lib/python${pythonEnv.pythonVersion}/site-packages:${pythonEnv}/${pythonEnv.sitePackages}" \
      --set GI_TYPELIB_PATH "$GI_TYPELIB_PATH:${glib}/lib/girepository-1.0:${gtk4}/lib/girepository-1.0:${libadwaita}/lib/girepository-1.0:${graphene}/lib/girepository-1.0:${glib}/lib/girepository-1.0:${pango}/lib/girepository-1.0:${gdk-pixbuf}/lib/girepository-1.0" \
      --add-flags "$out/lib/python${pythonEnv.pythonVersion}/site-packages/boxflat/entrypoint.py --data-path $out/share/boxflat/data"
  '';

  meta = with lib; {
    homepage = "https://github.com/Lawstorant/boxflat";
    changelog = "https://github.com/Lawstorant/boxflat/releases/tag/${version}";
    description = "Boxflat for Moza Racing. Control your Moza gear settings!";
    mainProgram = "boxflat";
    license = licenses.gpl3;
    maintainers = [ maintainers.jensereal ];
    platforms = platforms.unix;
  };
}

it is now packaging but I’m getting an error when trying to run the program

Data path: /nix/store/96hrr3h4gcskhmg989mzdzfmxlh7q71r-boxflat-v1.25.2/share/boxflat/data

(process:96176): Gtk-WARNING **: 15:27:23.436: Unknown key gtk-modules in /home/<user>/.config/gtk-4.0/settings.ini

(python:96176): Adwaita-WARNING **: 15:27:23.589: Using GtkSettings:gtk-application-prefer-dark-theme with libadwaita is unsupported. Please use AdwStyleManager:color-scheme instead.
Segmentation fault (core dumped)

Someone has an idea what I can do about it? And I’m sure that you can optimize the package, but this is the first time for me trying to package an app.

Any help is appreciated :slight_smile:

With great help of your post and this repo I’ve been able to get something going for now. I’m not quite happy yet as it’s not the latest version.

See here for my progress so far.
