aiogo 0.1.2

Tiny helper for running your async code

😈 What the heck?

aioGo is the tiny helper library that doing two simple thinks:

• run your async code

and

• correct terminate your async code

Default python asyncio have troubles with this: when you hit Ctrl+C asyncio just cancel all your coroutines.

This can lead to many race conditions and hanging your application at exit point.

📘 How to use?

Install from pypi:

pip install aiogo

or, if you prefer poetry:

poetry add aiogo

And just:

from asyncio import Future
from aiogo import go

async def main(termination: Future[bool]) -> None:
    await termination

if __name__ == "__main__":
    go(main)

That's all. You just wait while termination future was resolved (when your application got SIGINT or SIGTERM).

When you will be use this library in real world, just:

import asyncio

async def main(termination: asyncio.Future[bool]) -> None:
    done, _ = asyncio.wait((termination, your_awesome_read_task), return_when=asyncio.FIRST_COMPLETED)

and check done set.

I want custom event loop (uvloop)!

That I have! Again, just:

import uvloop
from aiogo import go

go(main, event_loop_factory=uvloop.new_event_loop)

I want forced exit!

If you can't write correct exit behaviour, well... Do that:

from aiogo import go
go(main, exit_timeout=10)

And all your coroutines will be got CancelledError, as doing old good asyncio.run.
