Async support

[shomodj]

Interesting tool, I like that it is similar to invoke, I just wish it supported async. Do you think this is complex to add? @pawamoy

[pawamoy]

Interesting idea @shomodj! Could you show a use-case where async support would be useful?

[pawamoy]

I see, thanks! So basically you'd like to define async functions that work as duties, right?

@duty
async def my_task(ctx):
    ...

Have you tried running your coroutines directly with asyncio.run?

@duty
def my_task(ctx):
    ctx.run(asyncio.run, args=[your_coroutine])

[pawamoy]

More concrete example:

import asyncio

# let say you have an async func
async def async_task() -> None:
    print("Sleeping...")
    await asyncio.sleep(1)
    print("done!")

@duty
def async_duty(ctx: Context) -> None:
    # run it like that:
    ctx.run(asyncio.run, args=[async_task()], title="Running an async task")

[shomodj]

yes, exactly, this will support asyncio without any shenanigans

[pawamoy]

I suppose you mean "yes, async def my_duty so that I don't have to asyncio.run"? OK! I'm sure we can do the asyncio.run part ourselves when running the duty 🙂 Doesn't sound like a complicated change. Can you open a feature request?

[shomodj]

sorry, yes

@duty
async def task(ctx: Context) -> None:
    await async.sleep(1)
