py3support 0.1.1

Check which of your dependencies already support python 3.

Usage

Example:

$ py3support requirements.txt

Python 3 support level: 50% (2/4)

Python 3
========
  requests==1.0.4
  docutils==0.10

Python 2
========
  Flask==0.9

Unknown
=======
  PIL==1.1.6

How it works

The only easy way to tell if package supports python 3 is to trust author’s classifiers. This tool hits PyPI index to check what python versions do your dependencies support.

Caveats

Some packages might support python 3, but do not have required metadata, some packages might state py3 support, but it’s not there yet (gunicorn). After all, a lot of package authors don’t provide python version classifiers at all.

Todo

• If not requirements.txt exists make use of pip freeze
• Check python 3 compatibility for latest version in PyPI
• Handle development versions -e
• Search for python 3 forks at github
• Handle package names with wrong CaSe (?)
