def instrument
  @_instrument ||= begin
    ::Sinatra::Base.class_eval do
      alias_method :cs__patched_sinatra_base_call!, :call!
      # publicly available method for Sinatra::Base things -- unfortunately,
      # getting the routes appear to require a lookup every time
      def call! *args
        Contrast::Framework::Sinatra::Patch::Base.map_route(cs__class, settings, *args)
        cs__patched_sinatra_base_call!(*args)
      end
    end
    true
  end
end

.map_route(clazz, settings, *args) ⇒ Object

Use logic copied from Sinatra::Base#process_route to determine which pattern matches the request being invoked by Sinatra::Base#call!

Parameters:

  • clazz (Class) —

    the Class that extends Sinatra::Base in which this route is defined.

  • settings (Object) —

    the Sinatra::Base @settings object.

  • args (Array<Object>) —

    we rely on the @settings object in Sinatra::Base and the env variable passed in as args.
