python2nix

Put a PyPI package name in, get a Nix expression out to add to nixpkgs or your private build scripts.

Quick start

• Choose your favorite package from PyPI (like https://pypi.python.org/pypi/thumbor)
• Feed its name to python2nix: python -mpython2nix thumbor
• Use code from stdout as the base for Nix expression (it may need manual tweaks).

nix-shell -p pythonPackages.virtualenv
virtualenv env
env/bin/pip install -r pip.requirements
mkdir -p env/build
env/bin/python -mpython2nix thumbor | tee thumbor.nix

Known issues

• You will need to convert md5 to sha256 manually.
• Tested only with pip==1.5.6.
• May ignore lots of the metadata (e.g. doesn't handle tests_require).
