I’ve now pushed the work I mentioned to
- GitHub - nix-community/pip2nix: Freeze pip-installable packages into Nix expressions [maintainer=@datakurre]
- GitHub - nix-community/setup.nix: Nixpkgs based build tools for declarative Python packages [maintainer=@datakurre]
I have never known all the use cases for pip2nix, so there must be a lot of issues and polishing left (and I’m also missing PyPI rights for it).
Yet, I managed to package Plone with these with relatively little custom rules: https://github.com/nix-community/setup.nix/blob/36d367f6f7588d00f1de8f011409bd6477a2a5c9/examples/plone/setup.nix
