	end

	def end_date

kcurtin / rspec_macro.vim

Created May 22, 2013 18:40

For anyone working with a test suite that uses the original (soon to be deprecated?) "should" syntax for rspec, this is a nice little macro that will convert shoulds to expects

	" Example:
	" response.body.should have_content("something")
	" expect(response.body).to have_content("something")

	" =================================================
	" Macro that converts rspec "should"s to "expect"s
	" =================================================
	function! ConvertToExpect()
	:normal! dd
	:normal! P
