Folks, for years I've been debugging Rev projects with what I now
realise is a rather poor subset of the available facilities:
basically I have set breakpoints, stepped through code using the
debugger, and looked at variables using the Variable Watcher.
Now however I have a tricky 'how did I get here?' type of question
which involves me wanting to know the caller of a particular handler,
and the caller of the caller etc. I think this may perhaps be
accomplished by using the undocumented executionContexts which has
been written about recently. So far, I've noticed that at the top of
the Variable Watcher window there is a dropdown list which may be a
form of this: it gives the names of the objects in which scripts
leading to the breakpoint were executed, and a line number in each.
It doesn't contain the names of any handlers, and AFAIK I can't
display line numbers in scripts, so this is of limited use in a
really large script. In the RR docs the description of the variable
watcher is not long, to say the least, and I don't think there's a
tutorial about it either.
Can anyone point me at a more in-depth description of the debugging
facilities of Rev?
Can't do that, but I can give you a couple more hints.
In the Variable Watcher, just to the right of the drop-down menu of
objects/contexts, there is a button like a scroll of paper. Clicking on
that will take you to the script line of the currently selected context.
Also, in the script editor, you can use the menu View / Go to line ...
to go to a line number. Unfortunately, you can't do that while in
debugger mode - the whole View menu is not enabled at that point.
