This is the development version of Vim's included runtime files for the Ruby acceptance testing framework Cucumber. It provides syntax highlighting, indenting, and some editing commands.
vim-cucumber provides commands to jump from steps to step definitions in feature files.
In normal mode, pressing [<C-d> or ]<C-d> on a step jumps to the
corresponding step definition and replaces the current buffer. <C-W>d or
<C-w><C-d> on a step jumps to its definition in a new split buffer and moves
the cursor there. [d or ]d on a step opens the step definition in a new
split buffer while maintaining the current cursor position.
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/tpope/vim-cucumber.git
