smqueue¶ ↑

github.com/seanohalpin/smqueue

version 0.3.0

DESCRIPTION¶ ↑

Implements a simple protocol for using message queues, with adapters for ActiveMQ, Spread and stdio (for testing).

This is a bare-bones release to share with my colleagues - apologies for the lack of documentation and tests.

FEATURES¶ ↑

• simple to use

• designed primarily for pipeline processing

• compatible with Rails

• comes with a modified stomp.rb library (rstomp.rb)

BUGS¶ ↑

• let me know!

SYNOPSIS¶ ↑

require 'smqueue'
config = YAML::load(File.read('config.yml'))
input_queue = SMQueue(config[:input])
output_queue = SMQueue(config[:output])
input_queue.get do |msg|
   # do something with msg
   new_msg = msg.body
   output_queue.put new_msg
end

Configuration¶ ↑

The easiest way to configure SMQueue is to use YAML files. An example can be found in ./examples/config/example_config.yml.

To find out the complete set of options each adapter supports, for now you’ll have to read the source in ./lib/smqueue/adapters/*.rb.

REQUIREMENTS¶ ↑

• depends on doodle >= 0.1.9

• you need access to an ActiveMQ message broker or Spread publisher

• development uses bones gem

INSTALL¶ ↑

For runtime:

sudo gem install doodle smqueue

For development:

sudo gem install bones
