" File: pylint_fn.vim
" Author: Roman 'gryf' Dobosz (gryf73 at gmail.com)
" Version: 1.0
" Last Modified: 2010-09-11
"
" Description: " {{{
"
" Overview
" --------
" This plugin provides ":Pylint" command, which put pylint result into quickfix
" buffer. This function does not uses pylint[1] command line utility, only
" python pylint.lint module is used instead. So it makes the pylint
" egg/package required for running this script.
"
" This script uses python, therefore VIm should be compiled with python
" support. You can check it by issuing ":version" command, and search for
" "+python" inside features list.
"
" Couple of ideas was taken from pyflakes.vim[2] plugin.
"
" Installation
" ------------
" 1. Copy the pylint_fn.vim file to the $HOME/.vim/ftplugin/python or
" $HOME/vimfiles/ftplugin/python or $VIM/vimfiles/ftplugin/python
" directory. If python directory doesn't exists, it should be created.
" Refer to the following Vim help topics for more information about Vim
" plugins:
" :help add-plugin
" :help add-global-plugin
" :help runtimepath
" 2. It should be possible to import pylint from python interpreter (it should
" report no error):
" >>> import pylint
" >>>
" If there are errors, install pylint first. Simplest way to do it, is to
" use easy_install[3] shell command as a root:
" # easy_install pylint
" 3. Restart Vim.
" 4. You can now use the ":Pylint" which will examine current python buffer
" and open quickfix buffer with errors if any.
