  # Registers jQuery.Turbolinks by monkey-patching jQuery's
  # `ready` handler. (Internal)
  #
  # [1] Trigger the stored `ready` events on first load.
  # [2] Override `$(function)` and `$(document).ready(function)` by
  #     registering callbacks under a new event called `turbo:ready`.
  #
  register: ->
    $(@onLoad) #[1]
    $.fn.ready = @addCallback #[2]

# Use with Turbolinks.
