.. _asyncio:
Running on top of the `asyncio` event loop
==========================================
.. note::
New in prompt_toolkit 3.0. (In prompt_toolkit 2.0 this was possible using a
work-around).
Prompt_toolkit 3.0 uses asyncio natively. Calling ``Application.run()`` will
automatically run the asyncio event loop.
If however you want to run a prompt_toolkit ``Application`` within an asyncio
environment, you have to call the ``run_async`` method, like this:
.. code:: python
from prompt_toolkit.application import Application
async def main():
# Define application.
application = Application(
...
)
result = await application.run_async()
print(result)
asyncio.get_event_loop().run_until_complete(main())
