This library works with Ruby 1.8, Ruby 1.9 and JRuby.

This library was tested primarily with RabbitMQ, although it should be compatible with any
server implementing the AMQP 0-8 spec.

To use with RabbitMQ, first run the server:

  hg clone http://hg.rabbitmq.com/rabbitmq-codegen
  hg clone http://hg.rabbitmq.com/rabbitmq-server
  cd rabbitmq-server
  make run

To get started, refer to the various bundled examples:

  ruby examples/mq/simple.rb     # low-level Queue/Exchange api
  ruby examples/mq/pingpong.rb   # 1-1 communication using amq.direct
  ruby examples/mq/clock.rb      # 1-N communication using amq.fanout
  ruby examples/mq/stocks.rb     # 1-subscriber communication using amq.topic
  ruby examples/mq/hashtable.rb  # simple async rpc layer
  ruby examples/mq/primes.rb 4   # parallelized prime number generation
  ruby examples/mq/logger.rb     # simple logging api

For more details into the lower level AMQP client API, run the simple client example:

  ruby examples/amqp/simple.rb   # low-level AMQP api

Or refer to protocol/doc.txt, which enumerates packets sent between a server and client
during a typical session, in both binary and decoded formats.

To run the test suite:

  rake spec

The lib/amqp/spec.rb file is generated automatically based on the AMQP specification. To generate it:

  rake codegen

This project was inspired by py-amqplib, rabbitmq, qpid and rubbyt.
