Constructor Details

#initialize(arg_list) ⇒ ConfigFile

Create the config file object. args is the list of arguments from the command line.

The following command line options are handled early here rather than later at the time most command options are processed.

  • –config-file and –config-file==NAME – Obviously these need to be handled by the ConfigFile object to ensure we get the right config file.

  • –backtrace – Backtrace needs to be turned on early so that errors before normal option parsing can be properly handled.

  • –debug – Enable Ruby level debug messages. Handled early for the same reason as –backtrace.
