asyncio event loop isn't closed on exit

See original GitHub issue

When run with Python 3.8.5 on Ubuntu 20.04 LTS, the event loop isn’t closed when the example is quit by pressing q.

Following error is output and the program exists:

/usr/lib/python3.8/asyncio/base_events:654: ResourceWarning: unclosed event loop <_UnixSelectorEventLoop running=False closed=False debug=False>

The terminal is then printing raw bytes (?) of the mouse movement anytime you move the cursor over the window.

I’m not sure if it’s the Python version or some difference between Linux and OSX.

(In order to run the example I had to patch src/textual/_parser.py, because the type hint list[str] isn’t supported in 3.8. I just replaced it with list.)

Yeah, there is an entire shutdown procedure I need to figure out.

Not sure if you know this, but if your terminal gets messed up like this you can enter “reset” command.

That’s fixed in a branch I’m working on.
