pyflakes-vim
============

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
------------------

1. Make sure your ``.vimrc`` has::
 
    filetype on            " enables filetype detection
    filetype plugin on     " enables filetype specific plugins

2. Download the latest release_.

3. If you're using pathogen_, unzip the contents of ``pyflakes-vim.zip`` into
   its own bundle directory, i.e. into ``~/.vim/bundle/pyflakes-vim/``.

   Otherwise 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).

Running from source
-------------------

If you're running pyflakes-vim "from source," you'll need the PyFlakes library
on your PYTHONPATH somewhere.  (It is included in the vim.org zipfile.) I recommend
getting my PyFlakes_ fork, which retains column number information, giving more
specific error locations.
