![Example*
function! GetHTML()
python << EOF
import vim, BeautifulSoup, urllib
handle = urllib.urlopen(vim.current.line)
soup =
BeautifulSoup.BeautifulSoup(handle.read())

Vim and Python
- 1. Vim and Python Derek McLoughlin Jolt Online Gaming 8th June 2011
- 2. Overview ● Intro ● Why use Vim? ● Basic Vim concepts ● Vim is a Game ● General Plugins ● Python Plugins ● How to Organise your plugins ● Resources
- 3. Why Vim? ● It's fast. ● It's portable. Linux, Windows, Mac, DOS, VMS ● It's everywhere – even on production systems ● It's very configurable ● It's very extensible
- 4. Basic Concepts #1 - Modes ● Vim is modal ● It has 5 modes ● Normal ● Insert ● Ex ● Visual ● Select ● You'll find yourself pressing <ESC> a lot :-)
- 5. Basic Concepts #2 - Commands ● Commands follow a pattern: Number + Command + Destination ● E.g. ● 5dw – delete 5 words ● 6w – move forward 6 words ● 7x – delete 7 characters
- 6. Vim is a Game (that you play on text) ● When you play a PC game (e.g. Minecraft) you forget that you need to press specific keys to do something – WASD. After a while, those actions are programmed into your finger muscles. ● You “do”. You don't “think”. ● You can practice Vim movements this with Vim Tetris ● Movement keys are always on the right hand.
- 7. Vim Leverages Unix ● Example: ● :%!sort ● :'<,'>!sort ● :%!awk '{print $3}' ● :%!sed 's/foo/bar/'
- 8. General Plugins NerdTree NerdCommenter NerdTree NerdCommenter Bufferlist Matchit Command-T SnipMate Ack Fugative Tagging & Tagbar Extradite DBExt Gitv Rails.vim
- 9. Python Plugins ● Python Match ● RopeVim ● PyFlakes ● Pydoc ● Pep-8
- 10. Organising Plugins ● Old School – all plugins in same folder – a mess! ● .vim -> doc -> ftplugin -> plugin ● Use Pathogen ● Use Vundle
- 11. Scripting Vim ● Vim has an in-built scripting language ● VimScript or VimL ● It's ugly. ● Use Python instead!
- 12. Example* function! GetHTML() python << EOF import vim, BeautifulSoup, urllib handle = urllib.urlopen(vim.current.line) soup = BeautifulSoup.BeautifulSoup(handle.read()) vim.current.buffer[:] = soup.prettify().split('n') EOF endfunction * I took this from: http://www.builderau.com.au/program/python/soa/Extending-Vim-with-Python/0,2000064084,339283181,00.htm
- 13. Vim is Charityware ● Donations to Vim go to a charity that helps orphans in Uganda. ● If you do like Vim and you feel it is making you more productive, then please donate to this charity. ● The details are on the Vim website.
