I suggest we create a Python packages folder where we add one package file for each one and handle that automatically.

One way we can do that is using and use that to add that to the Python namespace automatically. Take a look at how we do it back in our project:

...
      perSystem = { self', config, system, pkgs, ... }: {
        _module.args.pkgs = import inputs.nixpkgs {
          inherit system;
          overlays = [
            (_: prev: {
              python3 = prev.python3.override {
                packageOverrides = _: _:
                  inputs.by-name.lib.trivial prev.python3Packages.callPackage ./pkgs/python-by-name;
              };
            })
          ];
        };
...

It would allow you to have one folder for each package and make it easy to go upstream in the future.

your fork @maxhbr works for me on nixpkgs stable (nixos-24.11) and with zephyr 4.1.0.

The only problem I have noticed so far is an evaluation warning for invalid ruff constraints, but the dev shell seems to be working fine.

works for me aswell thanks @maxhbr

it tested it for zephyr-4.1.0 and nixpkgs-unstable:
the gcovr package will move to top level in nixpkgs, with these changes it worked:
