loops - How to break outer cycle in Ruby?

Question

In Perl, there is an ability to break an outer cycle like this:

AAA: for my $stuff (@otherstuff) {
         for my $foo (@bar) {
             last AAA if (somethingbad());
         }
      }

(syntax may be wrong), which uses a loop label to break the outer loop from inside the inner loop. Is there anything similar in Ruby?

Answer 1

Consider throw/catch. Normally the outside loop in the below code will run five times, but with throw you can change it to whatever you like, breaking it in the process. Consider this perfectly valid ruby code:

catch (:done) do
  5.times { |i|
    5.times { |j|
      puts "#{i} #{j}"
      throw :done if i + j > 5
    }
  }
end
