Out-of-the-box vim setup is good, but with a few tweaks it gets much better. Install the full version instead of the minimal and also exuberant ctags, which are great for programmers using vim. They let you navigate in the source code like you do in a full fledged IDE .

   1  sudo apt-get install vim exuberant-ctags

Then place the content below into your ~/.vimrc file.

   1  set nocompatible
   2  syntax on
   3  filetype plugin indent on
   4  runtime! macros/matchit.vim
   5  set autoindent          " always set autoindenting on
   6  set smartindent         " smartindent! :)
   7  set nobackup " nobackup
   8  :colorscheme oceandeep
   9  augroup myfiletypes
  10    " Clear old autocmds in group
  11    autocmd!
  12    " autoindent with two spaces, always expand tabs
  13    autocmd FileType ruby,eruby,yaml set ai sw=2 sts=2 et
  14  augroup END
