Send and receive messages without thinking about it

Send messages without really thinking about it. Currently works with Amazon’s SQS.

DSN

You configure your connection using a dsn in the form:

InterfaceName://username:password@?param1=value1&param2=value2

So, to connect to SQS, you would do:

morp.interface.sqs.SQS://AWS_ID:AWS_KEY@

You can also override some default values like region and read_lock:

morp.interface.sqs.SQS://AWS_ID:AWS_KEY@?region=us-west-1&read_lock=120

If you set the environment variable MORP_DSN with your connection dsn then morp will automatically configure itself on first import.

1 Minute Getting Started

Send and receive a Foo message.

First, let’s set our environment variable:

export MORP_DSN=morp.interface.sqs.SQS://AWS_ID:AWS_KEY@

Second, let’s create a Foo class:

import morp

class Foo(morp.Message):
    pass

Third, let’s get Foo ready to receive messages:

while True:
    with Foo.recv() as foo_msg:
        print foo_msg.fields

Fourth, let’s send a message:

f = Foo()
f.some_field = 1
f.some_other_field = 2
f.send()

And we’re done, you can check out the actual example in the /example folder on Github to see similar code to the above in action.
