Wanted to share a quick tool that I wrote to remove the tedious nature of creating python derivations for packages that will be submitted to nixos/nixpkgs. Was wondering of other such tools that exist? I have seen pip2nix and pypi2nix but they seem more oriented toward developing outside of nixpkgs.
It is at https://github.com/costrouc/nixpkgs-dev-tools/blob/master/python/python-package-init.py python-package-init.py will create a default.nix in the current directory. It parses the pypi json api along with mock running setup.py to get all of the dependencies. It gets 80-90% of the work done for you and removes the boring tedious stuff.
For a simple example python-package-init.py filterpy will grab the latest filterpy release from pypi.
{ pkgs
, buildPythonPackage
, fetchPypi
, numpy
, scipy
, matplotlib
}:
buildPythonPackage rec {
pname = "filterpy";
version = "1.4.5";
src = fetchPypi {
inherit pname version;
sha256 = "4f2a4d39e4ea601b9ab42b2db08b5918a9538c168cff1c6895ae26646f3d73b1";
};
buildInputs = [ ];
checkInputs = [ ];
propagatedBuildInputs = [ numpy scipy matplotlib ];
meta = with pkgs.lib; {
description = "Kalman filtering and optimal estimation library";
homepage = https://github.com/rlabbe/filterpy;
license = licenses.MIT;
# maintainers = [ maintainers. ];
};
}
It also handles complex examples well too. python-package-init.py hacking --version 1.0.0
