A Vim plugin for checking Python code on the fly.
PyFlakes catches common Python errors like mistyping a variable name or accessing a local before it is bound, and also gives warnings for things like unused imports.
pyflakes-vim uses the output from PyFlakes to highlight errors in your code. To locate errors quickly, use quickfix commands like :cc.
Make sure to check vim.org for the latest updates.
Quick Installation
Make sure your .vimrc has:
filetype on " enables filetype detection filetype plugin on " enables filetype specific plugins
Download the latest release.
Unzip pyflakes.vim and the pyflakes directory into ~/.vim/ftplugin/python (or somewhere similar on your runtime path that will be sourced for Python files).
Installation
If you downloaded this from vim.org, then just drop the contents of the zip file into ~/.vim/ftplugin/python.
Otherwise, if you're running "from source," you'll need PyFlakes on your PYTHONPATH somewhere. I recommend getting my PyFlakes fork, which retains column number information and has therfore has more specific error locations.
Hacking
git clone git://github.com/kevinw/pyflakes-vim.git cd pyflakes-vim git clone git://github.com/kevinw/pyflakes.git
