Overview

This class wraps the original OptionParser to “repair” some bad behaviour.

Instance Method Details

#add_officious ⇒ Object

Usually, OptionParser adds default handlers for help, version, etc. This is a undocumented behavoir and some cases not intended, because the default handler also stops execution immediately. Thatswhy we remove some of them.

def add_officious
  super
  base.long.reject! { |_key, _| _key == "help" || _key == "version" }
end

#parse!(argv) ⇒ Object

The original option parser stops processing if it sees any options it does not know. This implementation uses order!, which is a lower level OptionParser method to get the requested behavior. Because #parse uses #parse! internally, this automatically fixes #parse.
