Usage with qtile

Hello! Me again! Sorry about that! 😅

I’d like to custom-build the python-based qtile window manager, but I don’t quite know how to override or merge the derivation below with the default package; with xonsh, there was the package option, but there’s nothing similar for qtile.

let

  # mach-nix = import (builtins.fetchGit {
  #  url = "https://github.com/DavHau/mach-nix/";
  #  ref = "refs/tags/2.3.0";
  # });
  mach-nix = import ../../extras/mach-nix;
  pkgs = mach-nix.nixpkgs;

  # build the xonsh package similar like in nixpkgs
  qtile_pkg = with pkgs.qtile; mach-nix.buildPythonPackage {
    inherit src LC_ALL postPatch postInstall passthru;
    # inherit src LC_ALL postPatch postInstall passthru pythonPath;
    add_requirements = ''
      # cairocffi-xcffib
      cairocffi
      setuptools
      setuptools_scm
      xcffib

      # From https://github.com/NixOS/nixpkgs/issues/45039
      dateutil
      dbus-python
      iwlib
      keyring
      mpd2
      psutil
      pythonwifi
      pyxdg

      # add requirements here
      # ...
    '';
  };

  # build environment with xonsh + python packages from arbitrary sources
  qtile_env = mach-nix.mkPython {
    extra_pkgs = [
      qtile_pkg
      "https://gitlab.com/picotech/nanotech/nanite/-/archive/master/nanite-master.tar.gz"
    ];
  };

  # wrap it again to set the passthru variable correctly
  qtile_wm = with pkgs.qtile; pkgs.buildEnv {
    inherit name passthru;
    paths = [ qtile_env ];
  };

in qtile_wm

Thank you kindly for the help!

No worries. Always happy to help. Looking forward to merge your examples!

Looks fine to me. Didn’t test though
