aioawait

This package implements two primitives (await and spawn) on top of asyncio infrastructure of Python 3. This two functions allow us to call asynchronous functions from synchronous code.

Installation

pip3 install aioawait

Example

from asyncio.tasks import coroutine, sleep, async
from aioawait import await, spawn

@coroutine
def monitor(name, size, total):
    while True:
        print('\ttotal', name, total)
        yield from sleep(1)

@coroutine
def counter(name, size, total):
    """sums into total all numbers from 0 to size"""
    m = async(monitor(name, size, total))

    # monitor could be called using spawn. eg:
    # m = spawn(monitor(name, size, total))

    for n in range(size):
        total[0] += n
        if n % 5 == 0:
            print('sleeping', name, n)
            yield from sleep(2)
        else:
            print('counting', name, n)
            yield

    # stops monitor
    m.cancel()

    return name, 'done', n, total

class Counter:
    """note that this class has no asynchronous code"""

    def __init__(self):
        self.cb = spawn(counter('b', 40, [0]))

    @property
    def counter_a(self):
        return await(counter('a', 20, [0]))

    @property
    def counter_b(self):
        return await(self.cb)

if __name__ == '__main__':
    c = Counter()
    print(c.counter_a)
    print(c.counter_b)
