Pernalonga

Pernalonga is a simple wrapper for the Ruby gem Bunny. While Bunny has all classes and methods for utilizing an AMQP queuing system, the code for doing so can take up a lot of space and tends to be repeated across many projects.

Usage

Pernalonga sets up the logic of publishing and subscribing to queues and processing messages.

Connection Configuration

Your connection configurations must be environment variables.

Pernalonga uses dotenv to autoload any information you have in a .env file.

A sample .env file would contain the following required variables.

BUNNY_USER=abc
BUNNY_VHOST=abc
BUNNY_PASSWORD=abc
BUNNY_HOST=abc

Consuming

You don’t have to setup all the Bunny objects for Connections, Channels and Queues and arrange your message processing logic within them.

Instead, the only required thing is to simply implement a process_message method in your class. This way, once you call Pernalonga.consume self, "queue_name" to process messages from a queue, Pernalonga will call back your process_message method passing the message as the unique parameter.

Enqueuing

To enqueue messages just use Pernalonga.enqueue "queue_name" message.

Installation

Add this line to your application's Gemfile:

gem 'pernalonga'

And then execute:

$ bundle

Or install it yourself as:

$ gem install pernalonga

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
