vim-pyflakes

Installation

1. Install pyflakes
2. Copy the file ftplugin/python_pyflakes.vim to your ~/.vim/ftplugin directory

Usage

1. Open a Python file
2. Press <F7> to run pyflakes on it

It shows the errors inside a quickfix window, which will allow your to quickly jump to the error locations by simply pressing [Enter].

Customization

If you don't want to use the <F7> key for pyflakes-checking, simply remap it to another key. It autodetects whether it has been remapped and won't register the <F7> key if so. For example, to remap it to <F3> instead, use:

autocmd FileType python map <buffer> <F3> :call Pyflakes()<CR>

Tips

A tip might be to run the Pyflakes check every time you write a Python file, to enable this, add the following line to your .vimrc file (thanks Godefroid!):

autocmd BufWritePost *.py call Pyflakes()

This plugin goes well together with the following plugins:

• PEP8 (Python coding style checker under <F6>)
• PyUnit (unit test helper under <F8> and <F9>)
