A tool to convert python wheels to eggs

Project Description

For when you need an .egg but all you have is a .whl.


Humpty is a command-line utility to convert Python binary wheel packages to eggs.

Currently, the tool is in a “works for me” state. (It is not guaranteed to work for you.)

Development takes place on github. The package is installable from PyPI


The humpty “man page”:

$ humpty --help
Usage: humpty [OPTIONS] WHEELS...

  Convert wheels to eggs.

  -d, --dist-dir DIR  Build eggs into <dir>.  Default is <cwd>/dist.
  --help              Show this message and exit.

Suppose you need an egg of a distribution which has only been uploaded to PyPI as a wheel:

$ pip install --download . publicsuffixlist
  Saved ./publicsuffixlist-0.2.8-py2.py3-none-any.whl
Successfully downloaded publicsuffixlist

$ humpty -dist-dir . publicsuffixlist-0.2.8-py2.py3-none-any.whl
Converting publicsuffixlist-0.2.8-py2.py3-none-any.whl to publicsuffixlist-0.2.8-py2.6.egg

$ easy_install publicsuffixlist-0.2.8-py2.7.egg

Release 0.2 (2017-11-08)

Python 2.6 is no longer supported. We now test under cpython 2.7 and cpython 3.3 through 3.6.

Changed Behavior

  • The strict check for wheel binary compatibility with the current platform has been removed. Now a warning is printed in this case. When running under py35 or py36, distlib sometimes falsely reports that some wheels are not binary compatible. See distlib ticket #93.

Bugs Fixed

  • Fix EggInfo_Legacy.requires to work with recent versions of distlib. With distlib<=0.2.4, distlib.wheel.Wheel.metadata.run_requires is a list of strings, taken from lines of the RFC822 style metadata. With recent versions of distlib, run_requires is a list of dicts in the “JSON” format described in PEP 426. This addresses #1.
  • Always create eggs with zip_safe=False. There currently seems to be no robust way to determine whether a package is zip_safe from its wheel. See #3 for further discussion. (Thank you to immerrr.)
  • Fix parsing of markers in EggInfo_Legacy.requires. Apparently, as of distlib==0.2.6, distlib.markers.interpret no longer handles leading whitespace in the marker string well.
  • Fix failing test test_humpty:TestScriptCopyer.test_copies_script. Apparently, distlib.markers.interpret==0.2.6 now just prepends the new hashbang line to the copied script, but does not remove the original hashbang.
