@override
Future<bool?> execute(String caller, String propertyOrFunction, List<dynamic> arguments) async
{
  if (scope == null) return null;
  var function = propertyOrFunction.toLowerCase().trim();
  switch (function)
  {
    // show template
    case "showtemplate":
      showTemplate();
      return true;
  }
  return super.execute(caller, propertyOrFunction, arguments);
}
