A quick script for fast conversion of punycode from/to ascii and unicode

punycode.rb

#!/usr/bin/env ruby -w

require 'simpleidn'
require 'getoptlong'

opts = GetoptLong.new(
  [ '--help', '-h', GetoptLong::NO_ARGUMENT ],
  [ '--unicode', '-u', GetoptLong::REQUIRED_ARGUMENT ],
  [ '--ascii', '-a', GetoptLong::REQUIRED_ARGUMENT ]
)

opts.each do |opt, arg|
  case opt
  when '--help'
    puts "For converting to punycode use --ascii [parameter]"
    puts "For converting to unicode  use --unicode [parameter]"
    puts "Example: punycode --ascii пипец.рф"
  when '--unicode'
    puts "Result:  #{SimpleIDN.to_unicode(arg)}"
  when '--ascii'
    puts "Result: #{SimpleIDN.to_ascii(arg)}"
  else
    puts "Call up for --help, you're getting crazy!"
  end
