Globally import uasyncio

[Nico]

Hi,

I'm trying to add micropython support to HBMQTT, an MQTT client/broker I've been developing.
One task is to correctly import micropython renamed modules like uasyncio. Therefore, I've added this kind of statements to my python code:

Code: Select all

try:
    import uasyncio as asyncio
except:
    import asyncio
 

This works fine and allow to support both CPython and micropython within the same code.
Problems come with dependencies. For example, HBMQTT uses websockets module which also import asyncio. This fails when importing on microypthon, but I can't fix by modifying this third-party library.
So, i was wondering if there was a way in python to globally replace all "imports asyncio" to import "uasyncio as asyncio". May be byoverriding "__import__". Does anyone know how to do this ?

uasyncio isn't fully compatible with asyncio. If you depend on 3rd-party libraries, you will likely find that they don't work as expected and require porting themselves.

But otherwise, the (hackish) answer to your question should be obvious - create file "asyncio.py" on uPy search path with content "from uasyncio import *".

More sustainable approach is implementing sys.modules (on TODO for some time, patches welcome) and using it.
