la-com-request-parser 0.2.0

A request parser to simplify communication with physics-lab devices

LabAutomation Communication Request Manager

In the context of a physics lab automation project, this package aims to simplify communication with different devices. Communication is based on 0mq and json-based messages. This package is meant to be used in combination with a 0mq-based device server.

Sending a request

The only relevant function to use is ReqParser.request(): Parameters:

• device: to be addressed device name as string (defined in Device Server)
• action: requested action as string ("connect", "disconnect", "test", arbitrary)
• payload: values to be passed for arbitrary action

Returns:

• status: True (successful) or False (communication request failed)
• info: string of more detailed information

Including / Replacing Communication Manager

By using the following import line, the package can be used: from la_com_request_parser.com_request_parser import ReqParser

If you previously used the Communication Manager and it is deeply rooted in the project you can just import the following line to maintain full functionality: from la_com_request_parser.com_request_parser import ReqParser as CommunicationManager
