Subject: optparse problem grabbing a value

Hi folks,

I'm trying to switch from getoptlong to optparse. I'm having a problem
grabbing a value from the command line. Here's the code:

-----------
cat example.rb

#!/usr/bin/env ruby
require "ostruct"
require "optparse"

options = OpenStruct.new

options.date = false

option_parser = OptionParser.new do |opts|
  opts.on("-d", "--date", String, "Optional: Specify date in format
00-00-00") do |date|
    options.date = date
  end
end

puts "<#{options.date}>"

-------------

If I run:

ruby example.rb -d 12-07-12

I expected the output:

<12-07-12>

instead I saw:

<false>

What am I doing wrong?


best

Jams
