# Bunny, a Ruby RabbitMQ Client Bunny is a synchronous RabbitMQ client that focuses on ease of use. It is feature complete, supports all RabbitMQ 3.0 features and does not have any heavyweight dependencies. ## I Know What RabbitMQ and Bunny are, How Do I Get Started? [Right here](http://rubybunny.info/articles/getting_started.html)! ## What is Bunny Good For? One can use amqp gem to make Ruby applications interoperate with other applications (both Ruby and not). Complexity and size may vary from simple work queues to complex multi-stage data processing workflows that involve many applications built with all kinds of technologies. Specific examples: * Events collectors, metrics & analytics applications can aggregate events produced by various applications (Web and not) in the company network. * A Web application may route messages to a Java app that works with SMS delivery gateways. * MMO games can use flexible routing RabbitMQ provides to propagate event notifications to players and locations. * Price updates from public markets or other sources can be distributed between interested parties, from trading systems to points of sale in a specific geographic region. * Content aggregators may update full-text search and geospatial search indexes by delegating actual indexing work to other applications over RabbitMQ. * Companies may provide streaming/push APIs to their customers, partners or just general public. * Continuous integration systems can distribute builds between multiple machines with various hardware and software configurations using advanced routing features of RabbitMQ. * An application that watches updates from a real-time stream (be it markets data or Twitter stream) can propagate updates to interested parties, including Web applications that display that information in the real time. ## Supported Ruby Versions Bunny 0.9 and more recent versions support * CRuby 1.9.3, 1.9.2, 2.0.0, and 1.8.7 * JRuby 1.7+ * Rubinius 2.0+ ## Supported RabbitMQ Versions Bunny `0.8.x` and later versions only support RabbitMQ 2.x and 3.x. Bunny `0.7.x` and earlier versions support RabbitMQ 1.x and 2.x. ## Project Maturity Bunny is a mature library (started in early 2009) library with a stable public API. Before version 0.9, **a lot** of functionality was missing. Version 0.9 can be considered to be "second birthday" for Bunny as it was rewritten from scratch with over a dozen of preview releases over the course of about a year. We (the maintainers) made our best effort to keep the new version as backwards compatible as possible but within reason. ## Installation & Bundler Dependency ### Most Recent Release [![Gem Version](https://badge.fury.io/rb/bunny.png)](http://badge.fury.io/rb/bunny) ### With Rubygems To install Bunny with RubyGems: ``` gem install bunny ``` ### Bundler Dependency To use Bunny in a project managed with Bundler: ``` ruby gem "bunny", ">= 1.0.0.rc2" ``` ## Quick Start Below is a small snippet that demonstrates how to publish and synchronously consume ("pull API") messages with Bunny. For a 15 minute tutorial using more practical examples, see [Getting Started with RabbitMQ and Ruby using Bunny](http://rubybunny.info/articles/getting_started.html). ``` ruby require "bunny" # Start a communication session with RabbitMQ conn = Bunny.new conn.start # open a channel ch = conn.create_channel # declare a queue q = ch.queue("test1") # publish a message to the default exchange which then gets routed to this queue q.publish("Hello, everybody!") # fetch a message from the queue delivery_info, metadata, payload = q.pop puts "This is the message: #{payload}" # close the connection conn.stop ``` ## Documentation ### Getting Started For a 15 minute tutorial using more practical examples, see [Getting Started with RabbitMQ and Ruby using Bunny](http://rubybunny.info/articles/getting_started.html). ### Guides Other documentation guides are available at [rubybunny.info](http://rubybunny.info): * [Queues and Consumers](http://rubybunny.info/articles/queues.html) * [Exchanges and Publishers](http://rubybunny.info/articles/exchanges.html) * [AMQP 0.9.1 Model Explained](http://www.rabbitmq.com/tutorials/amqp-concepts.html) * [Connecting to RabbitMQ](http://rubybunny.info/articles/connecting.html) * [Error Handling and Recovery](http://rubybunny.info/articles/error_handling.html) * [TLS/SSL Support](http://rubybunny.info/articles/tls.html) * [Bindings](http://rubybunny.info/articles/bindings.html) * [Using RabbitMQ Extensions with Bunny](http://rubybunny.info/articles/extensions.html) * [Durability and Related Matters](http://rubybunny.info/articles/durability.html) ### API Reference [Bunny API Reference](http://reference.rubybunny.info/). ## Community and Getting Help ### Mailing List [Bunny has a mailing list](http://groups.google.com/group/ruby-amqp). We encourage you to also join the [rabbitmq-discuss](https://lists.rabbitmq.com/cgi-bin/mailman/listinfo/rabbitmq-discuss) mailing list. Feel free to ask any questions that you may have. ### IRC For more immediate help, please join `#rabbitmq` on `irc.freenode.net`. ### News & Announcements on Twitter To subscribe for announcements of releases, important changes and so on, please follow [@rubyamqp](https://twitter.com/#!/rubyamqp) on Twitter. More detailed announcements can be found in the blogs * [RabbitMQ Ruby clients blog](http://blog.rubyrabbitmq.info) * [Bunny Blog](http://bunnyamqp.wordpress.com) ### Reporting Issues If you find a bug, poor default, missing feature or find any part of the API inconvenient, please [file an issue](http://github.com/ruby-amqp/bunny/issues) on GitHub. When filing an issue, please specify which Bunny and RabbitMQ versions you are using, provide recent RabbitMQ log file contents if possible, and try to explain what behavior you expected and why. Bonus points for contributing failing test cases. ## Other Ruby RabbitMQ Clients Other widely used Ruby RabbitMQ clients are [March Hare](http://rubymarchhare.info) (JRuby-only) and [amqp gem](http://rubyamqp.info). Both are mature libraries and require RabbitMQ 2.x or 3.x. ## Contributing First, clone the repository and run bundle install --binstubs then set up RabbitMQ vhosts with ./bin/ci/before_build.sh (if needed, set `RABBITMQCTL` env variable to point to `rabbitmqctl` you want to use) and then run tests with CI=true ./bin/rspec -cfs spec After that create a branch and make your changes on it. Once you are done with your changes and all tests pass, submit a pull request on GitHub. ## License Released under the MIT license.
