MacVim

UPDATE: I'm off the Mac for development and onto Ubuntu so now see at the link for the latest version of my .vimrc file for PHP.

MacVim configuration should be put in a file called "gvimrc" in your user directory:

~/.gvimrc

Here are some configurations used for Drupal:

set expandtab
set tabstop=2
set shiftwidth=2
set autoindent
set smartindent
