Issue #5010 has been updated by rosenfeld (Rodrigo Rosenfeld Rosas).


Thomas, I like the idea but there is a shortcoming to this approach when people are using Ruby for performing shell scripting, like sysadmin scripts. It is not fair to force them to install any gem for some common task like this...

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:

http://lee.jarvis.co/slop/

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>
