A small wrapper around lib2to3 that provide warnings messages for Python 3 incompatible code.
Project description
# py3kwarn [][travis]
py3kwarn is a small wrapper around lib2to3 to help write Python3 compatible code. It provides flake8-style warning messages.
Currently requires Python 2.7+.
See the [lib2to3][lib2to3] documentation for information on warning messages.
Pull requests are welcome!
## Usage
py3kwarn test.py
## Usage with vim
To use with vim, check out [my syntastic fork][my-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 let g:syntastic_python_checkers=[‘flake8’, ‘py3kwarn’] to your vim config.
## TODO
An option for friendlier messages would be nice.
[A flake8 extension][flake8-ext].
Use argparse to add some smarter options.
Better docs
Make it work with Python 2.6
