Larva is a selection of helper classes used in Meducation's [pub/sub](http://en.wikipedia.org/wiki/Publish-subscribe_pattern) network. It builds upon [Propono](github.com/meducation/propono) and [Filum](github.com/meducation/filum).

## Installation

Add this line to your application's Gemfile:

    gem 'larva'

And then execute:

    $ bundle install

## Usage

### Listeners

Larva Listeners provide an easy way of listening to a Propono topic and processing the message, complete with lots of logging through Filum.

```ruby
class MyProcessor
  def self.process(message)
  end
end

Larva::Listener.listen(:my_topic, MyProcessor, "queue_suffix")
```
