Questions tagged [eventmachine]

EventMachine is a fast, reactor pattern library for Ruby programs. It provides non-blocking IO APIs with transparent internal buffers and standard reactor features (such as defer, next_tick and timers). (note to future editors: Eventmachine itself does not use Fibers, and the core does not use threads for any IO, timers or core infrastructure).
