How to add capybara dsl syntax highlighting to vim syntax highlighting?

I'm using Tim Pope's rails.vim plugin and for the most part it highlights nearly everything I want, except Capybara's new DSL which contains keywords like feature, scenario, background etc.

I don't want to create a new syntax file just for those two keyword开发者_StackOverflow中文版s, just need to add them to the existing one.

Found rails.vim file which holds syntax stuff and added the keywords.

elseif buffer.type_name('spec') syn keyword rubyRailsTestMethod describe context it its specify shared_examples_for it_should_behave_like before after subject fixtures controller_name helper_name feature scenario background
