Issue #5010 has been updated by Shyouhei Urabe.


I'm neutral about that proposed #to_hash (so far, bit vague), but is definitely far better than removing optparse.  Can you let your proposal be a new ticket?  This thread is already too long to read through.

----------------------------------------
Feature #5010: Add Slop(-like) in stdlib and deprecate current OptionParser API

I always found the OptionParser API not as well designed as it could be.

I've just found this gem:

Much better API and I think we should integrate it to Ruby 2.0.

Take a look at the minimal example shown in OptionParser :

<pre>
  require 'optparse'

  options = {}
  OptionParser.new do |opts|
    opts.banner = "Usage: example.rb [options]"

    opts.on("-v", "--[no-]verbose", "Run verbosely") do |v|
      options[:verbose] = v
    end
  end.parse!

  p options
  p ARGV
</pre>

This is the equivalent in Slop:

<pre>
require 'slop'

opts = Slop.parse do
  banner "Usage: example.rb [options]"
  on :v, :verbose, "Run verbosely", :default => true
end

p opts.to_hash
</pre>
