LightIO

LightIO provide green thread to ruby. Like Golang's goroutine, or Crystal's fiber. In LightIO it called beam.

LightIO ship ruby stdlib compatible library under LightIO or LightIO::Library namespace, these libraries provide ability to schedule LightIO beams when IO operations occur.

See Examples for detail.

LightIO also provide a monkey patch, it replace ruby Thread with LightIO::Thread, and also replace IO related classes.

Example:

LightIO::Monkey.patch_all!
# now you can just write normal ruby code
start = Time.now
10.times.map do
  Thread.new do
    `sleep 1`
  end
end.each(&:join)
puts Time.now - start

You Should Know

In fact ruby core team already plan to implement Thread::Green in core language, see https://bugs.ruby-lang.org/issues/13618

It mean if ruby implemented Thread::Green, this library is no meaning to exists. But as a crazy userland implemented green thread library, it bring lot's of fun to me, so I will continue to maintain it, and welcome to use

See Wiki and Roadmap to get more information.

LightIO is build upon nio4r. Get heavily inspired by gevent, async-io.
