Support pyproject.toml as requirement format

[DavHau]

Some projects use pyproject.toml instead of requirements.txt to specify their requirements. It would be great to support this format.

This also needs to be added to the crawler.

Relevant PEPs:
PEP-518

Is there any progress on this issue?

How can I use mach-nix if a package does not have a setup.py but pyproject.toml only?

[DavHau]

Hey, unfortunately there is no progress on this so far. PR's are welcome.

As long as your package's build backend is supported by pkgs.buildPythonPackage, then you can also use mach-nix.buildPythonPackage.
Just provide the list of requirements via requirements argument.
You probably have to pass format = "pyproject" as well. See mk-python-derivation.nix in nixpkgs

Thank you!
