[Cuis-dev] Some discussion on mini debugger

[Hilaire Fernandes]

Hi Juan, folks,

In my mini-debugger for simple-human-being, there is one problematic 
behavior.

 From the debugger, when an error, the user can't step over the next 
instruction when using the step button. In the picture bellow the "Step" 
button has the same behavior of "step over" in the traditional debugger. 
I would expect Step to lead to the next line.

I was wondering if the suspended process should not be resumed once the 
debugger is in place?

So I just added,  "ex resume" after the debugger is installed, during 
the exception handling. And it works! Now when the user presses the 
"Step" button, the debuggers step to the next line, after the error. But 
now, if the user insist to step on error, this leads to recursive 
debugger call.

So in that case, I decided to not resume the process, instead stop the 
existing debugger and inform the user to fix error. A bit sub optimal 
but user should stop stepping at this point and fix previous error. With 
kids and newbies, they will put the system on its knee in an eye blink

Interested on opinion and idea.
