Hi All,

Quick progress report.

1. I created a mockup of Bert's SqueakJS. Its stubbed out, but the run and help button work. If anybody can tell me where to pull the current context from the vm sim, I can replace the bottom middle panel with that.
It currently uses:

SimpleHierarchicalListMorph on: [ Array with: (ObjectExplorerWrapper with: (self model vm) name: 'root' model: (self model vm) parent: nil) ] where 'vm' is the running StackInterpreterSimulator.

So something like:

SimpleHierarchicalListMorph on: [ Array with: (ObjectExplorerWrapper with: (self model vm getTheActiveContext) name: 'root' model: (self model vm somethingOrOtherToHangTheActiveContextUnder) parent: nil) ]

would be appreciated if its easy.


2. Ah, events, events, events...how do I know thee...let me count the ways.

Standard Morphic events are created by HandMorph>>processEvents when invoked by  WorldState doOneCycleNowFor:

HandMorph grabs the raw evtBuf array off the Sensor (exactly as I forwarded in round one of this) and then wraps them to make them handy for Morphic. Unfortunately what is handy for Morphic is not handy for the VM Simulator.

2.a. The obvious solution is to reverse the wrapping. I do not see any existing work that does this, and it looks a bit daunting. My hunch is that I will have to do it. At that point, you can ridicule my lack of low-level bit fiddling experience.

2.a.1 Unfortunately, HandMorph's addEventListener/sendListenEvent/handleListenEvent event broadcasting framework sends these wrapped events.

2.b. I modified HandMorph and added a parallel event broadcasting/listener framework with addPrimitiveEventListener/sendListenPrimitiveEvent/handleListenPrimitiveEvent and that works just fine. I am able to subscribe to the primitive events from
my Morph's model and forward them to the vm simulator--just like with my previous approach with EventSensor.

2.b.1 I am going to continue with this for a bit, as next up, I think I can improve performance by injecting only those events that fall within the bounds of the ImageMorph that houses the simulated World. I will be on that tomorrow.

2.c. Tim R. requested a means to feed events directly to the simulator. The eventListener framework in HandMorph can be ported to the GUI in 10 minutes, so there is hope there.

3. After 2.b.1, I am going to see about injecting Morphic Events that only occur on the ImageMorph that houses the simulated World. I started with this approach initially, but chickened out when I saw the wrapping task and went with  the 2 series instead.

I will try to get a clean copy of my code to you all in a couple of days. I have a lot of missteps in my work due to the various approaches I am trying, so its a bit messy at the moment.


Anyway, that's the update.


cordially,
