module Responders
  module ControllerMethod
    # Adds the given responders to the current controller's responder, allowing you to cherry-pick
    # which responders you want per controller.
    #
    #   class InvitationsController < ApplicationController
    #     responders :flash, :http_cache
    #   end

    # Takes symbols and strings and translates them to VariableResponder (eg. :flash becomes FlashResponder).
    # Also allows passing in the responders modules in directly, so you could do:
    #
    #    responders FlashResponder, HttpCacheResponder
    #
    # Or a mix of both methods:
    #
    #    responders :flash, MyCustomResponder
