module Runner


  # The main thing a runner does is <tt>run()</tt>. Each runner will
  # actually take a different number of arguments, so their
  # <tt>run()</tt> signatures will differ. This stub is only here to
  # let you know that it needs to be implemented.
  #
  # @param args [Array<Object>] whatever arguments the real implementation
  #   would take.
  #
  def run(*args)
    raise NotImplementedError
  end


  # Report a message from the given *plugin*. All this does is prefix
  # the message with the plugin name and then print it to stdout.
  #
  # @param plugin [Object] t plugin object that generated the message
  #   we're reporting.
  #
  # @param msg [String] the message to report.
  #
  def report(plugin, msg)
    print "#{plugin.class.to_s()} - "
