It's practical uses depend, more of less, on whether or not you are dealing with bytecodes or not. If you are the it's quite useful to see how values are being pushed/popped from the stack. Also the normal debugger executes multiple bytecode instructions at once.

As part of that we need a data structure that holds scopes, for variables but also for other things. It turns out that for the variables part we can map rather nicely to classes, which gives us a bunch of advantages. So for each scope I generate a class. The scope keeps that class in a âvarsâ instance variable (there are never any instances of these classes BTW). When the scope is garbage collected I want to remove the class from the system. So I put #finalize in the scope with the idea to remove the class, but it turns out that âvarsâ is always nil. So in the end it did not work out ... You're probably registering the scope for finalization before setting the vars insvar? The shadow copy is made at the point of registration, so any subsequent assignments to the scope's instvars is not accounted for. Cheers, Henry

wow nice, great job Andrei what are the practical uses for this debugger, does it also allow you change the bytecode as the regular debugger allow you to change code ?

Hi, What do you mean by a Roassal plugin? You mean a debugger dedicated to debugging Roassal problems, or you mean Roassal visualizations for various debuggers? To both the answer is that it is easy to do. If you want to see an example of using a Roassal visualization inside a debugger, you can take a look at the Glamour Debugger, but essentially you just have to create a browser like any other and put in there a Roassal presentation.

As Iâve been asked, Iâll clarify a bit more. When I said it worked before I was actually wrong because I had forgotten to remove some alternative cleanup code (the alternative works but itâs like using a cannon to kill a fly). This is part of the interpreter for Live Robot Programming that Miguel and I are working on. As part of that we need a data structure that holds scopes, for variables but also for other things. It turns out that for the variables part we can map rather nicely to classes, which gives us a bunch of advantages. So for each scope I generate a class. The scope keeps that class in a âvarsâ instance variable (there are never any instances of these classes BTW). When the scope is garbage collected I want to remove the class from the system.

So in the end it did not work out ... > On Jan 15, 2015, at 15:10, Henrik Johansen <henrik.s.johansen(a)veloxit.no> wrote: > > Removing a class you're an instance of might be a bit fishy as well. (as I understand were to be the case if you only implement #finalize), though it'd be nice with some details why it "didn't work out" for Johan. ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

I am quite interested in plugin a Roassal visualization to a debugger. I will discuss with Rosario, but maybe you have worked on something on your side? Would it be hard to have this?

Roassal and super large screen

by Alexandre Bergel

Dear all, We have reached a milestone today. We have been able to make Roassal display on a super large screen gently provided by INRIA Chile. If there would be a contest on displaying Roassal-made visualizations on the largest (and most expensive) super-screen ever, then we will be on a good run. >From the technical point of view, we export SVG and use a cluster-friendly SVG renderer. This expands the range of what can be achieved.

[ANN] A simple debugger for stepping though bytecodes.

by Andrei Chis

Hi all, We've just made a simple debugger for stepping through bytecodes. It's still just the first version so a lot of things can still be improved. More info here: https://chisvasileandrei.wordpress.com/2015/01/15/a-bytecode-debugger/ Cheers, Andrei
