Fire periodic callback when lua console receives '\r'

[vadosnaprimer]

If debugger is open, entering commands into lua console becomes problematic. The console only updates on periodic callbacks, and those don't fire frequently enough if lua console has focus. One has to hover the mouse over MAME or debugger window after every lua command not to have to wait for each command to get processed.

I'm not sure how hard this may be do implement though, it'd have to explicitly connect linenoise to MAME via a callback?

@cracyc am I overcomplicating this?

Linenoise runs in it's own thread so it doesn't block the emulation waiting for input. The periodic check is called while the debugger is stopped at https://github.com/mamedev/mame/blob/master/src/emu/debug/debugcpu.cpp#L1666 which is followed by a call to wait_for_debugger. wait_for_debugger at least on windows calls GetMessage which is where things stop. On windows then linenoise could send a message to the debugger window to poke it into action, processEvents on qt platforms. Personally, I decided to live with it rather than deal with the complexity but that's what's happening if you want to try.

I noticed that it does arrive after a few seconds of just waiting too. Is it the timeout for the periodic callback itself, or for debugger auto-updates?

Which platform? On windows the window may just eventually receive a message. It's not going to do anything until GetMessage returns.

Yeah, Windows.
