Transparent convert any asyncio futures and inline yield methods to tornado futures.

Project Description


Write on tornado with asyncio easy.


Transparent convert any asyncio futures and inline yield methods to tornado futures.



import tornado.gen
import asyncio
from tornado.ioloop import IOLoop
from toasyncio.gen import coroutine

def test():
    print('Tornado future')
    yield tornago.gen.sleep(1)
    print('Asyncio future')
    yield from asyncio.sleep(1, loop=IOLoop.current().asyncio_loop)



import asyncio
from tornado.gen import sleep
from toasyncio.testing import gen_test, AsyncTestCase

class TestBasic(AsyncTestCase):
    def test_all_together(self):
        step = 0.1
        count = 10
        t0 = self.io_loop.time()

        for i in range(count):
            yield sleep(step / 2)
            yield from asyncio.sleep(step / 2, loop=self.aio_loop)

        self.assertTrue((t0 + (count * step)) <= self.io_loop.time())
