py3kwarn 0.1.1

A small wrapper around lib2to3 that provide warnings messages for Python 3 incompatibilities

py3kwarn is a small wrapper around lib2to3 to help write Python3 compatible code. It provides flake8-style warning messages.

See the lib2to3 documentation for information on warning messages.

Pull requests are welcome!

Installation

Requires Python 2.7+

$ pip install py3kwarn

…or to install from the git repository:

$ git clone git://github.com/liamcurry/py3kwarn.git
$ cd py3kwarn
$ make install

Usage from the command line

$ py3kwarn [filename]

Usage with vim

To use with vim, check out my syntastic fork which adds py3kwarn as a syntax checker for python. If you want to use py3kwarn and syntastic with another syntax checker (like flake8), then you will have to add this to your vim config:

let g:syntastic_python_checkers=['flake8', 'py3kwarn']

TODO

• An option for friendlier messages would be nice.

• A flake8 extension.

• Use argparse to add some smarter options.

• Better docs

• Make it work with Python 2.6
