toasyncio

Write on tornado with asyncio easy.

About

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

Examples

Using

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

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

IOLoop.current().run_sync(test)

Testing

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


class TestBasic(AsyncTestCase):
    @gen_test
    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())
