March Hare is an idiomatic, fast and well-maintained (J)Ruby DSL on top of the RabbitMQ Java client. It strives to combine strong parts of the Java client with over 4 years of experience using and developing Ruby amqp gem and Bunny.

• Concurrency support on the JVM is excellent, with many tools & approaches available. Lets make use of it.
• RabbitMQ Java client is rock solid and supports every RabbitMQ feature. Very nice.
• It is screaming fast thanks to all the heavy duty being done in the pretty efficient & lightweight Java code.
• It uses synchronous APIs where it makes sense and asynchronous APIs where it makes sense. Some other Ruby RabbitMQ clients only use one or the other.
• amqp gem has certain amount of baggage it cannot drop because of backwards compatibility concerns. March Hare is a clean room design, much more open to radical new ideas.

March Hare is not

• A replacement for the RabbitMQ Java client
• An attempt to re-create 100% of the amqp gem API on top of the Java client
• A "work queue" like Resque
• A cure for cancer

March Hare is not a young project. Extracted from a platform that transports more than a terabyte of data over RabbitMQ every day, it has been around as an open source project since mid-2011 and has reached 2.0 in late 2013.

It is based on the RabbitMQ Java client, which is officially supported by the RabbitMQ team at Pivotal.

gem install march_hare

gem "march_hare", "~> 3.0.0"

MarchHare documentation guides are mostly complete.

Several code examples are available. Our test suite also has many code examples that demonstrate various parts of the API.

API reference is available.

March Hare supports JRuby 9.0 or later.

The project is tested against OpenJDK 8, Oracle JDK 8 and is known to work on OpenJDK 7 and Oracle JDK 7.

See ChangeLog.md.

CI is hosted by travis-ci.org

You'll need a running RabbitMQ instance with all defaults and management plugin enabled on your local machine to run the specs.

To boot one via docker you can use:

$ docker run -p 5672:5672 -p 15672:15672 rabbitmq:3-management

And then you can run the specs using rspec:

$ bundle exec rspec
