ALIOT-PY: The python implementation of the Aliot library!

What is Aliot?

Before everything else, aliot is a fancy websocket written in python that aims to facilitate iot focused exchanges between a server and a client

Installation

1. create a python virtual environment
   • run the command py -m venv venv
2. add aliot in a folder in your project (replace $FOLDER in the command by the name of your folder)
3. run the command pip install ./$FOLDER

Creating my first Aliot program

1. create an object ObjConnecte

Creating an endpoint (or, like we call it here, a protocol)

1. Create a function that takes some parameters

   # my function will take money ($) and give cookies for every 2$ received
   def give_cookies_for_money(money: int):
       return {"cookies": money // 2}
   

2. Register your function as a protocol by decorating it with the on_recv decorator in your ObjConnecte that you created for your project and pass the id of your protocol in the argument of the decorator

   # here, I chose that my function will be protocol 34
   @my_iot.on_recv(action_id=34)
   def give_cookies_for_money(money: int):
       return {"cookies": money // 2}
   

3. As of now, my function give_cookies_for_money doesn't return anything to the server, if I want to send back my cookies, I have to ways:

   1. use the function my_iot.send()

   @my_iot.on_recv(action_id=34)
   def give_cookies_for_money(money: int):
       my_iot.send({"cookies": money // 2})
   

   1. set the convenience parameter send_result to True in the decorator

   @my_iot.on_recv(action_id=34, send_result=True)
   def give_cookies_for_money(money: int):
       return {"cookies": money // 2}
   

   1. You're all set! Now repeat and enjoy! 🎉

Order of execution (once run() is called)

1. obj.on_start()

• On receive:
  1. [ interceptor.intercept_recv() ]
  2. decoder.decode_event(event: dict) -> AliotEvent
  3. controller.handle_event(event: AliotEvent) -> None
  4. decoder.decode_data(data: dict) -> T
• On send:
  1. encoder.encode_data(data: Any) -> dict
  2. encode.encode_event()
  3. obj.__send_event() -> None
