#load_configuration_file(config_file_name = nil, block_for_missing = nil) ⇒ Object

This method takes care of parsing and using the configuration file as values Call this once you know where the config file might be located Take a look at how ‘gym` uses this method

Parameters:

  • config_file_name (String) (defaults to: nil) —

    The name of the configuration file to use (optional)

  • block_for_missing (Block) (defaults to: nil) —

    A ruby block that is called when there is an unkonwn method in the configuration file
