vim-chef is a Vim plugin which detects Chef cookbook and Chef-Repo files and sets the filetype to 'ruby.chef'. This enables other plugins like Syntastic to work with Chef files, e.g. running Foodcritic automatically on file save.
vim-chef also appends to Vim's 'path' to make 'gf' work on include_recipe lines in Chef recipe files. For example, if you have these lines in your cookbook's recipes/default.rb file:
include_recipe 'git'
include_recipe 'git::source'
include_recipe 'current_cookbook::my_other_recipe''gf' with the cursor on the recipes above would jump to 'git/recipes/default.rb', 'git/recipes/source.rb', and current_cookbook/recipes/my_other_recipe' respectively.
If you don't have a preferred installation method, I recommend installing pathogen.vim, and then simply copy and paste:
cd ~/.vim/bundle
git clone git://github.com/dougireton/vim-chef.git
