Futures and JRuby: The Omnibus Concurrency Library 0.2.1


#1

Just a quick note that I’ve released version 0.2.1 of the ‘concurrent’
gem, which provides Actors, data-parallel programming, and transparent
futures (plus lazy evaluation) for Ruby. This one adds:

  • Actor timeouts
  • Cleaned up support for Futures
  • Support for JRuby

Downloadables are here:

http://rubyforge.org/frs/?group_id=3690&release_id=12005

I’ll be working on documentation for the next release, but until then,
here’s a brief example of futures in action:

require ‘concurrent/futures’
include Concurrent::Futures

f = Future.async { 3 * 3 } # the block runs in a new thread
f.inspect # => #<Thunk #<Thread:0xdeadcafe run>>
f + 1 # waits for thread to complete, then => 10
f.inspect # => 9

Do you plan on releasing the scheduler dependency soon? :slight_smile:

Incidentally, I’d like to hear from anyone using the library – what
they like and what they don’t. It’ll help me a lot to decide where to
take things.

Also, sorry again about the scheduler mix-up. It should be uploaded
now.

Wow, I thought I’d already released it. Guess not though…
