-"""
-Inputhook for running the original asyncio event loop while we're waiting for
-input.
-
-By default, in IPython, we run the prompt with a different asyncio event loop,
-because otherwise we risk that people are freezing the prompt by scheduling bad
-coroutines. E.g., a coroutine that does a while/true and never yield back
-control to the loop. We can't cancel that.
-
-However, sometimes we want the asyncio loop to keep running while waiting for
-a prompt.
-
-The following example will print the numbers from 1 to 10 above the prompt,
-while we are waiting for input. (This works also because we use
-prompt_toolkit`s `patch_stdout`)::
-
- In [1]: import asyncio
-
- In [2]: %gui asyncio
-
- In [3]: async def f():
- ...: for i in range(10):
- ...: await asyncio.sleep(1)
- ...: print(i)
-
-
- In [4]: asyncio.ensure_future(f())
