Subject: Re: Need Help With OptionParser

Try this one:


require 'optparse'

p ARGV
puts

non_wrapper_options = []
opts = OptionParser.new do |opts|

  #wrapper option where value is required:
  opts.on("-t=RANDOM_CHARS") do |val|
    puts "-t option entered with value=#{val}"
  end

  #wrapper option where value is optional:
  opts.on("-y [=RANDOM_CHARS]") do |val|
    puts "-y option entered with value=#{val}"
  end

  #non-wrapper option where value is optional:
  opts.on("-a[=RANDOM_CHARS]") do |val|
    puts "-a option entered with value=#{val}"

    non_wrapper_options << '-a'
    if val
      non_wrapper_options << val
    end

  end
end


opts.parse(ARGV)

ARGV.replace(non_wrapper_options)
puts
p ARGV


--output:--
$ ruby optparseEx2.rb -y -thello -a goodbye
["-y", "-thello", "-a", "goodbye"]

-y option entered with value=
-t option entered with value=hello
-a option entered with value=

["-a"]
