"""Get input from the user and return it.
This is a wrapper around a lot of prompt_toolkit functionality and
can be a replacement for raw_input. (or GNU readline.) If you want
to keep your history across several calls, create one
`~prompt_toolkit.history.History instance and pass it every
time. This function accepts many keyword arguments. Except for the
following. they are a proxy to the arguments of
create_prompt_application().
Parameters
----------
patch_stdout : file-like, optional
Replace ``sys.stdout`` by a proxy that ensures that print
statements from other threads won't destroy the prompt. (They
will be printed above the prompt instead.)
return_asyncio_coroutine : bool, optional
When True, return a asyncio coroutine. (Python >3.3)
Notes
-----
This method was forked from the mainline prompt-toolkit repo.
