This library works with Ruby 1.8, Ruby 1.9, JRuby and Rubinius, and is licensed under the Ruby License.

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/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/multiclock.rb # header based routing (new rabbitmq feature)
  ruby examples/mq/ack.rb        # using ack
  ruby examples/mq/pop.rb        # pop off messages one at a time

  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
  ruby examples/mq/internal.rb   # low-level Queue/Exchange 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.
