In the past I've used gvim for Ruby coding. It's been pretty good, especially with the new tabbed editing and omni complete (bit like intellisense in Visual Studio) introduced in vim 7. However, when I downloaded vim at work, I was missing the secret sauce - a good vimrc. Here's my usual vimrc for ruby:
set nocompatible behave xtermset selectmode=mouse set nu set tabstop=2 set shiftwidth=2 set softtabstop=2 set ai set columns=100 set lines=70 set guifont=Courier:h10 set expandtab set smarttab let g:rubycomplete_rails = 1
Among other things, it makes the default window size bigger, uses a prettier font, sets up auto indenting ruby style, and turns on omni-complete.
By the way, on windows, assuming a default install, vimrc is to be found here:
