Configs

You need to configure these in your service:

{
    "PROJECT_ID": "...",
    "SUBSCRIPTION_NAME": "...",
    "TOPIC_NAME": "...",
    "MAX_MESSAGES": ...
}

Where: PROJECT_ID: qordoba project id e.g. qordoba-devel SUBSCRIPTION_NAME: a subscription to pull the messages from e.g. dev4.segment-delegator.gender-tone-pubsub.allLang TOPIC_NAME: where to publish the result messages e.g. dev4.segment-delegator.gender-tone-pubsub-latch.allLang MAX_MESSAGES: The maximum number of messages in the subscriber queue e.g. 100

Use PubSub only

Add this to the service application.py

    ps_connection = QPubSub(
        analyzer,
        white_lister=whitelister,
        category=category,
        verbose=VERBOSE,
        debug=DEBUG,
        ignore_html=IGNORE_HTML,
        sentence_token_limit=SENTENCE_TOKEN_LIMIT,
        ignore_inside_quotes=False
    )

    ps_connection.connect()

Use PubSub with REST

Add this to the service application.py

    rest_connection = QRest(
        analyzer,
        white_lister=whitelister,
        category=category,
        verbose=VERBOSE,
        debug=DEBUG,
        ignore_html=IGNORE_HTML,
        sentence_token_limit=SENTENCE_TOKEN_LIMIT,
        ignore_inside_quotes=False
    )
    ps_connection = QPubSub(
        analyzer,
        white_lister=whitelister,
        category=category,
        verbose=VERBOSE,
        debug=DEBUG,
        ignore_html=IGNORE_HTML,
        sentence_token_limit=SENTENCE_TOKEN_LIMIT,
        ignore_inside_quotes=False
    )

    ps_connection.connect_with_rest(rest_connection)

License

This software is not licensed. If you do not work at Qordoba, you are not legally allowed to use it. Also, it's just helper functions that really won't help you. If something in it does look interesting, and you would like access, open an issue.

TODO

• reduce compile time
• add tests
• handle errors, e.g. publish it to an error topic or return empty issues to the same topic.
