It's vim!

Typical .vimrc
------------------
Here's what a typical ``.vimrc`` looks like for me::
if has('syntax') && (&t_Co > 2)
syntax on
endif
set history=50
set wildmode=list:longest,full
set showmode
set showcmd
set smartcase
set shiftwidth=4
set tabstop=4
set shiftround
set expandtab
set autoindent
autocmd BufRead *.py set smartindent cinwords=if,elif,else,for,while,try,except, finally,def,class
Commands
-------------
Search and replace globally::
:%s/before/after/g
Tricks
-------------
I often want to pull a particular gnarly line or two from another file; here's
the command I use to grab three lines of context around 'phrase'::
:r!grep -A 3 'phrase' ../otherfile.txt
Pasting a lot of text with insert mode if very slow because vim redraws the
terminal for every single character entered (as you would want if you were
actually typing. To paste in the contents of the X11 clipboard you want to use::
"*P
(aka quote, star, uppercase-P) in regular mode. This also solves the
autotabbing problem without ":set paste"! You need to have "+xterm_clipboard"
in your ``vim --version`` output for this to work; the ``vim-gtk`` package on
newer Ubuntus has been compiled with this flag (?).
Sometimes you really need tab characters instead of space indendation (eg, when
editing Makefiles). To use tabs when editing a file use::
:set noexpandtab
If you accidently opened a file you can't write to, you can write out as root
using::
:w !sudo tee %
Search for trailing whitespace, or just strip it all::
/\s\+$
:%s/\s\+$//
Shell Sessions
-------------------
(discovered via
http://www.ktaylor.name/2009/11/vim-screen-lisp-programming-environment.html)
The emacs embeded interpreter mode is very nice for interactively programming
with languages like scheme and python. A similar effect can be achieved with
the `ScreenShell plugin
<http://www.vim.org/scripts/script.php?script_id=2711>`_ and the following
bindings:
vmap <C-c><C-c> :ScreenSend<CR>
nmap <C-c><C-c> vip<C-c><C-c>
nmap <C-x><C-e> :ScreenSend<CR>
`Slimv <http://www.vim.org/scripts/script.php?script_id=2531>`_ is a more
elaborate alternative (SLIME for vim).
Multi-Tab Setup
--------------------
TODO: document my current multi-window configuration, how to re-scale, etc.
``Ctrl-W =`` equalizes window sizes (``Ctrl-W`` is the vierport meta sequence).
Spellcheck
-------------
Do ``set spell`` to start spellchecking in "fly" mode (mispellings
highlighted); do ``set nospell`` to undo.
Hovering over a word in visual, do ``zg`` to add the word to your dictionary,
``z=`` to show suggestions,
