Component script debugger

Description (last modified by leper)

Component scripts are likely to get complex, so there needs to be a reasonable way to debug them. Currently there's just print() going to stdout, which isn't great.

Ideally there'd be a full graphical debugger with source code display and breakpoints and watches and stepping and so on. But that sounds really complex so maybe something simpler would be a more realistic idea.

The implementation should use (and likely also

The debugger should be able to pause execution. That means the thread running scripts will be paused inside its JS API calls, and the simulation will be in an inconsistent state. We could perhaps allow the engine to keep running (by using a reentrant game loop, or splitting the simulation into a secondary thread), but we'd need to be very careful since the engine isn't currently designed to do that. It might be better to implement the debugger as part of Atlas (which runs in its own independent thread), so it can communicate with an entirely paused engine, and also so it can use wxWidgets for the UI.

Noticed on #jsapi IRC:

Note that any new debugger work on top of jsdbgapi.h is likely to be throw-away code in a month or two! Or three. I think the new API will be much like

I've started working on something like that and would like to get it stable enough to commit until Alpha 13. I'll keep updating the forum thread:

Adds the server-side part of the javascript debugger. Refs #410

In 13239:

The original web GUI for the jsdebugger from contributor mmayfield45. I only removed the jquery demo directory and added some licensing information. This is for an older version of the debuggers server-side part, so it doesn't work anymore. The required modifications will be committed soon. Refs #410

My modifications to the jsdebugger's web GUI. Adds a few features and makes it compatible with the current server-side code. Closes #410

Component: UI & SimulationSimulation

Move tickets to Simulation as UI & Simulation got some sub components.
