Hi,
Observe the following:
ruby -e 'require "optparse"; o = OptionParser.new do |o| o.on("-c=C",
"desc") {|c|} end; o.parse([]); '
(Note the wrapping - it should all be on one line.)
Why doesn't this raise an error? I'm expecting -c to be a compulsory
argument, but OptionParser doesn't seem to mind (when it should, I
thought.)
How do I make OptionParser raise an error if it doesn't receive a '-c'
argument?
