This is the Python Paho template for the AsyncAPI generator.

It is basically working but may not generate perfect code for every AsyncAPI document. It works correctly with the temperature.yml file included in the samples directory, which demonstrates a subscriber, a publisher, and a payload class with an embedded enum type.

Support for arrays, specifying function names and other features are yet to be implemented.

In the samples directory there is an example of code that is close to what we intend to generate.

To run the sample code, copy config-template.ini to config.ini and enter the connection details.

If no authentication is needed, you need not provide the username and password values.

If no host is given, the template attempts to find an mqtt host in the servers section of the AsyncAPI document to use instead.

Note that this template interprets the AsyncAPI document in conformance with the AsyncAPI Specification. This means that when the template sees a subscribe operation, it will generate code to publish to that operation's channel. It is possible to override this, see the 'view' parameter in the parameters section below.

Install the AsyncAPI Generator

npm install -g @asyncapi/generator

Run the Generator using the Python Paho Template

ag ~/AsyncApiDocument.yaml @asyncapi/python-paho-template

Copy config-template.ini to config.ini and edit it to provide the connection details.

Parameters can be passed to the generator using command line arguments in the form -p param=value -p param2=value2. Here is a list of the parameters that can be used with this template. In some cases these can be put into the AsyncAPI documents using the specification extensions feature. In those cases, the 'info' prefix means that it belongs in the info section of the document.

The following specification extensions are supported. In some cases their value can be provided as a command line parameter. The 'info' prefix means that it belongs in the info section of the document.
