Example usage with requirements-dev.txt

[edmundmiller]

Hello, I'm trying to use mach-nix to add a flake for this package https://github.com/nf-core/tools

The problem is, they use a requirements-dev.txt. How should both the requirements.txt and requirements-dev.txt be included in the nix environment?

How about this (untested):

  mach-nix.mkPython {
    ...
    requirements = ''
      ${builtins.readFile "${src}/requirements.txt"}
      ${builtins.readFile "${src}/requirements-dev.txt"}
    '';
  };
```.

I came up with

          requirements = ''
            ${builtins.readFile ./requirements.txt}
            ${builtins.readFile ./requirements-dev.txt}
            python-lsp-server
            rich-click
            black
          '';

But I still can't do nix develop and then pytest, just checking that that's a good workflow.
