amqp-hermes's Introduction

amqp-hermes¶ ↑

A wrapper around ruby-amqp to make pub/sub live more easy.

Synopsis¶ ↑

Sending a message¶ ↑

# plain and simple
tr = AMQP::Hermes::Transmitter.new("test.queue.testing")
tr.transmit "payload"

# or as json
tr.transmit { :foo => "bar", :quex => "stuff" }.to_json

# with AMQP options
tr.transmit "payload", :persistent => true

# on a different queue
tr.transmit "payload", :routing_key => "test.queue.real"

Receiving a message with the simple build in handler¶ ↑

re = AMQP::Hermes::Receiver.new("test.queue")  # will listen on routing_key
                                               # test.queue.* be default
while !re.messages.any?
  sleep 0.1
end

puts re.messages.first.payload

Receiving with a custom handler¶ ↑

class MyCustomHandler
  def receive(message)
    if message.headers.routing_key =~ /test/
      $stderr.puts "Just a test, nothing to worry about"
      $stderr.puts message.payload

    else
      # ... do something incredible

    end
  end
end

re = AMQP::Hermes::Receiver.new("test.queue",
  :handler => MyCustomHandler.new
)

while(true); 
  # the receiver is at the ball now
end

Contributing to amqp-hermes¶ ↑

Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet.
Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it.
Fork the project.
Start a feature/bugfix branch.
Commit and push until you are happy with your contribution.
Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
