Parse the filename of a distribution

Python Help
1

Given I have a PEP compliant filename of a source distribution or wheel, like in the examples below:

dummypkg-1.0.24+ga45fb6f.master-py3-none-any.whl
dummypkg-1.0.24+ga45fb6f.master-pp310-pypy310_pp73-manylinux_2_17_x86_64.manylinux2014_x86_64.whl
dummypkg-1.0.24.tar.gz

Is there an official tool or library to extract information from that filename like:

  • Canonical package name (dummypkgs)
  • Version (1.0.24)
  • Local version (ga45fb6f.master)
  • ABI
  • Target Interpreters
  • Platform
  • a.s.o.

The packaging package has everything you need to deal with packaging metadata:

>>> from packaging.utils import parse_wheel_filename
>>> parse_wheel_filename("dummypkg-1.0.24+ga45fb6f.master-py3-none-any.whl")
('dummypkg', <Version('1.0.24+ga45fb6f.master')>, (), frozenset({<py3-none-any @ 139823742779584>}))
>>> parse_wheel_filename("dummypkg-1.0.24+ga45fb6f.master-pp310-pypy310_pp73-manylinux_2_17_x86_64.manylinux2014_x86_64.whl")
('dummypkg', <Version('1.0.24+ga45fb6f.master')>, (), frozenset({<pp310-pypy310_pp73-manylinux_2_17_x86_64 @ 139823742814592>, <pp310-pypy310_pp73-manylinux2014_x86_64 @ 139823742814656>}))
