Publishing¶

publish function¶

Use pyhermes.publish function to publish messages to Hermes.

import pyhermes

@pyhermes.publisher(topic='sample-topic')
def my_function():
    # processing
    pyhermes.publish(my_function._topic, {'result': result})

Note that after using pyhermes.publisher decorator, _topic attribute with the name of the topic is assigned to your function.

autopublishing result of the function¶

You could use auto_publish_result param to automatically publish result of the function to the given topic.

@pyhermes.publisher(topic='sample-topic', auto_publish_result=True)
def my_function():
    return {'result': 'abc'}

In this case, {'result': 'abc'} will be published with sample-topic topic after execution of the function.

Note that result of the function has to be JSON-serializable.
