What is amq-protocol.

amq-protocol is an AMQP 0.9.1 serialization library for Ruby. It is not an AMQP client: amq-protocol only handles serialization and deserialization.

If you want to write your own AMQP client, this gem will handle all the serialization needs for you, including RabbitMQ extensions to AMQP 0.9.1.

Supported Ruby Versions

amq-protocol 1.9.2 was the last version to support Ruby 1.8 and 1.9. amq-protocol 2.0.0 and later only supports Ruby 2.0+.


gem install amq-protocol


Make sure you have Python, pip and the mako templating package installed:

pip install mako

amq-protocol uses RabbitMQ protocol code generation library that is in Python, so there is some Python involved in the build.

To regenerate lib/amq/protocol/client.rb from the source (codegen/* files), run


To make changes, do not edit client.rb directly. Instead, edit the codegen/protocol.rb.pytemplate and regenerate.

To run tests, use

bundle install --binstubs
./bin/rspec -c spec spec
