[Octave-patch-tracker] [patch #8656] Variable Editor (expanded from Patch #8316)

[Philip Nienhuis]

Follow-up Comment #21, patch #8656 (project octave):

(Sorry I was away for over a week, have to catch up but my daily job has
priority (of course).)

A bug I just hit (a serious one I suppose) is that the variable editor doesn't
cope with cleared variables opened in the variable editor.

>> a = rand (3); b = num2cell (a); b{2, 2} = {1, "a"; "b", true};
>> clear b
>> Variable b not foundVariable b not found


(ignoring the duplicate popups).

Same for variables opened in the variable editor in functions openened in
debug mode. Once the function gets to the end and returns, the variable editor
tab keeps hanging, and has to be closed manually as well.

Apparently the variable editor doesn't get notified that b is gone, or went
out of scope. 

The relevant variable editor tab has to be closed manually before other work
can continue in the terminal.

As to structs, well, too bad :-)  
I find it already immensely useful to browse arrays and to see what happens
inside while debugging, even if only numeric and cell arrays. Thanks again for
your work on this!
