Toggle options at runtime about pytest-watch HOT 4 OPEN

Honestly for a while I was a little skeptical of officially adding support for this, since doing so turns the the current non-interactive tool (meaning no dependency on stdin or the terminal that hosts the app) into an interactive one.

Seems there's some interest though, so perhaps it'd be worth the extra complexity. We could add stdin or keyboard event monitoring to the main watch loop.

In theory this should be easy, like how adding a keyboard handler in the main loop of a game is easy. From working on py-getch, I can say, there's a chance keyboard monitoring (e.g. tty / stdin in "raw mode" / etc) won't be so straightforward unfortunately. Pytest-watch is cross platform, so this feature should be too.

Curious, can anyone point to other test runners that do this so we can draw inspiration about how to design the UI and keyboard-monitoring technique?

Makes total sense to me - thought so myself already.

Excellent!

I miss some Re-Run tests shortcut. By example, pressing R, tests re-run the same way when a file change event happens.

Just came across pynput. That could help with cross-platform keyboard monitoring.

Looks like setting up a monitor will run a callback, which is similar to how we handle file events today.
