Simulate "3+4" with InterpreterSimulator

Hi,

I have a InterpreterSimulator start up, in a workspace I type "3+4". From here, I want to step through bytecode per bytecode, when I hit "print". What should I do to achieve this?

Can I debug on the interpreter in the middle of the simulation? Or perhaps I need to put a "self halt" somewhere in the VM source?

Thanks.

I don't really know much about the InterpreterSimulator (and congrats
for getting it going! I never got it running...), but...

I would look for a primitive method somewhere which would cause the
simulated environment to stop and pop a debugger up in the host. You
would then evaluate that in the same method as "3+4".

If this primitive method doesn't exist, you could probably quickly
make one that just does "self halt.".

Try putting a self halt in Interpreter>>primitiveAdd, which should be
called when you evaluate "3+4".

The main interpreter loop is Interpreter>>interpret, which fetches
bytecodes and evaluates them. You can probably put a break in
InterpreterSimulator>>dispatchOn:in: which is called by #interpret
and simulates the big case statement that the interpreter loop
uses to dispatch bytecodes for execution.

Hi,

Here's a page, step by step guide to get InterpreterSimulator work, hope it helps.

That is awesome!

Can I ask very nicely if somebody could put the resulting image up on
http://squeakvm.org in an appropriately findable place, preferably
with a workspace set up with cool bits of code?

Does it specifically need VM version 3.9.2?

Cheers,
Gulik.

Or is it bytecodePrimAdd?

I can easily debug the InterpreterSimulator from the beginning. But, to move from the very beginning to the point where I can debug "3+4" would be very far, long, right? Or are there any way that I can do, to just skip to the part that I'm interested with.

Thank you so much for you help.

Thanks.

Hi, I have a InterpreterSimulator set up. Unzip, and you can play around with it already. Please let me know if you have any problem with it.

I think it does need 3.9 VM specifically, you can search previous nabble post about this.

Thanks.

This is awesome! :-). I'm amazed that computers are fast enough to run
this on a FULL image these days!!!

It runs kind of okay on my 3.11 Linux VM. There seems to be a font
problem; the workspace isn't drawing any text, although you can select
it where text is meant to be. Also event handling is a bit odd; the VM
doesn't seem to react even though CPU usage on the machine is near 0%.

Are you willing to tidy this up enough for putting on e.g.
ftp.squeak.org? I think this image is a great asset! It needs:

* You don't need the "package-cache", "sm" and "cs" directories. All
that stuff is in the image already.
* You can delete SqueakDebug.log.
* I don't know what the file .DS_store is, but its optional too.
* There's a halt in InterpreterSimulator>>lookupMethodInClass:

If you aren't willing to do this, I'll see if I can find free time this week.

Hi,

I will do that.

Halt in lookupMethodInClass: is done on purpose I believe. I'm not sure if it is ok to remove it.

Thanks.

Same here - runs fine on the latest Mac VM, but StrikeFonts do not show correctly.

You should remove the Windows VM from the zip, it's not needed. Anyone interested in this work will have a VM already ;-)

Hi,

Sorry, I miss this sentence previously. The text will show up after awhile. Sometimes, I'll need to rerun InterpreterSimulator for the text in workspace to show up. I tried to type, highlight and printIt, it's fine.

So, that means I remove those files, win VM, leave the image untouched. Is that ok?

Thanks.

Yes, for now. Then I'll ask the web team if we can upload it to ftp.squeak.org.

I'll see if I can work out why the StrikeFonts aren't working.

Actually:

http://askoh.com/mwiki/images/5/50/InterpreterSimulator-image.zip

You only forgot to remove squeak.ini which is only used by the Windows VM.

On the Mac it works with a 4.2.3 VM, but not the experimental 5.0 VM.

Some error when it's trying to simulate directory fetching.

Er, well a bit more information? Or point to a image/changes I can try?

ABSOLUTELY need more coffee, still recovering from an allnighter to get WikiServer on the iPad.
