py3kwarn 0.1.3

A small wrapper around lib2to3 to help write Python 3 compatible code.

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:

$ pip install -e git+git://github.com/liamcurry/py3kwarn.git#egg=py3kwarn

Usage from the command line

$ py3kwarn [filename]

Usage with vim

You can use py3kwarn with syntastic. If you want to use py3kwarn 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

• Friendlier messages.

• A flake8 extension.

• Use argparse to add smarter options.

• Make it work with Python 2.6

• Flags to ignore certain errors

• Compatibility mode, where warning messages provide suggestions to write forwards compatible code. Make this the default.

• Make it faster. Right now it is quite slow compared to other syntax checkers. Major refactoring may be necessary.

• tox support
