Adding and removing breakpoints on runtime?

[astrochili]

It looks like the debugger updates breakpoints only on onDebuggerStop(msg).

Is it possible to update breakpoints on setBreakPointsRequest(response, args) immediately or in some timer function?

I also want run time add remove breakPoints

This is challenging because lua has no built-in event loop. So, there's no straight-forward way to periodically check for incoming breakpoint changes.

A few potential options for supporting this:

• Poll for changes directly in the debug hook. This would slow down execution A LOT. It would probably be unusable.
• Provide a way to set an event loop manually. This would work for environments that have an update callback, but makes debugger setup more complicated.
• If remote debugging via sockets is added (Remote Debugging Support #2), this would likely be possible via that mode.

But what if we will call debugger.poll() from environment by a timer? Not every frame but for every second for example. Would it slow down execution?

I agree with @astrochili . A debugger.pollBreakpoints() would be awesome! The performance penalty for polling once per frame would be neglectable.
This could also totally be opt-in, so If you have an event loop - use it. If not don't - and get the same behaviour like now.

I think this should be do-able and useful. But I won't be able to get to it right away. It's on the roadmap though!

Are there any updates on this? LOVE environment has an update loop inside love.update (called every game loop) where lldebugger can pull for new datas, but user must integrate it themselves.
