aiocron provide a decorator to run function at time:
>>> @aiocron.crontab('*/30 * * * *')
... @asyncio.coroutine
... def attime():
... print('run')
>>> asyncio.get_event_loop().run_forever()
You can also use it as an object:
>>> @aiocron.crontab('1 9 * * 1-5', start=False)
... @asyncio.coroutine
... def attime():
... print('run')
>>> attime.start()
>>> asyncio.get_event_loop().run_forever()
Your function still be available at attime.func
You can also yield from a crontab. In this case, your coroutine can accept arguments:
>>> @aiocron.crontab('0 9,10 * * * mon,fri', start=False)
... @asyncio.coroutine
... def attime(i):
... print('run %i' % i)
>>> @asyncio.coroutine
... def once():
... try:
... res = yield from attime.next(1)
... except Exception as e:
... print('It failed (%r)' % e)
... else:
... print(res)
>>> asyncio.get_event_loop().run_forever()
Finally you can use it as a sleep coroutine. The following will wait until next hour:
>>> yield from crontab('0 * * * *').next()
If you don't like the decorator magic you can set the function by yourself:
>>> cron = crontab('0 * * * *', func=yourcoroutine, start=False)
Notice that unlike standard unix crontab you can specify seconds at the 6th position.
aiocron use croniter. Refer to
it's documentation to know more about crontab format.
