Class Method Details

.cache(type) ⇒ Object

Store all comparable items with their compare_value as the key and the item as the value

  • Reject any compare values that contain escapes #{} as that means they have unpacked constants

end

.match_step_to_step_definition_and_transforms(step) ⇒ Object

Given a step object, attempt to match that step to a step transformation

def process
  #
  # Features have already been created when they were parsed. So there
  # is no need to process the feature further. Previously this is where
  # feature steps were matched to step definitions and step definitions
  # were matched to step transforms. This only worked if the feature
  # files were were assured to be processed last which was accomplished
  # by overriding YARD::SourceParser to make it load file in a similar
  # order as Cucumber.
  #
  # As of YARD 0.7.0 this is no longer necessary as there are callbacks
  # that can be registered after all the files have been loaded. That
  # callback _after_parse_list_ is defined below and performs the
  # functionality described above.
