Subject: How can i do 'foreach (reverse sort { $hasref->{$a} <=> $hasref->{$b} } keys %{$hasref})..' in ruby

Hi,

I'am new with ruby and want to migrate some of my perlscripts to ruby ;-).

I have a problem with the 'reverse sort' of values of a hashref and hope
that sombody can help me or point me to the right way ;-)

I have found the a nice answer
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/30322

and have try the follwoing commands:

clients.values.sort{|a,b| a[1] <=> b[1]}.each {|k,v|
    puts "#{k} => #{v}"
}

clients.values.sort.reverse.each { |k|
  puts "#{k}"
}

but it looks to me that sort give me only a array back.

Here my perl code which i want to translate:

---
foreach (reverse sort { $hasref->{$a} <=> $hasref->{$b} } keys %{$hasref}){
  printf("% 7i %s\n",$hasref->{$_},      $_);
                     #^^^^^^^Key output  ^^value output  
}
---

Thanks for help

Aleks
