Subject: [ruby-core:56020] [ruby-trunk - Feature #8639] Add Queue#each


Issue #8639 has been updated by rkh (Konstantin Haase).


+1 for the feature, should have gone into CommonRuby, I think.

Feature #8639: Add Queue#each

I was fiddling around with Queue the other day and realized it doesn't have an #each method. So I made one: https://github.com/ruby/ruby/pull/361

As for why, it makes for a convenient way to build consumer processes:

  inq = Queue.new
  outq = Queue.new
  doubler = Thread.new do
    inq.each do |n|
      outq << n + n
    end
  end

My PR also returns an Enumerator when no block is given, and handles the non_block argument.

I'm sure there's some good reason that this method wasn't there already, so feel free to explain.

Also, this is my first Ruby feature ticket so please let me know if I'm missing any points of protocol.

Thanks!
