Depends what "on" means. :)
Remember that LiveCode is dynamically compiled - the only copy of a
script stored with a stack is the source copy, not any tokenized
version. So whenever you open a stack, as part of the unpacking its
scripts are dynamically compiled - and that's when the compilation error
will occur.
That is, if explicitVars is truly on.
If you're just turning it on via Prefs, in recent versions of LC that
merely sets a prefs value that causes explicitVars to be turned on only
for the moment a script is set; at all other times explicitVars isn't
really on at all (see the previous snippet from their IDE I posted that
illustrates that man behind the curtain).
But if you turn it on manually via the Message Box ("set the
explicitVars to true"), then you can see the behavior that happens when
you try to open a stack that has undeclared vars in its scripts - here I
get "can't create a variable with that name (explicitVars)".
So the good news is that RunRev's clever revamp of the IDE means we
never need to think about explicit vars for most projects, so those
turning it "on" via Prefs will never actually have it on unless they
open your script and try to save changes.
But the bad news is that it's just one more difference between how the
IDE works and how the engine works.
So when I wear my T-shirt which reads:
"Know the engine.
Trust the engine.
Use the engine."
...I need to add for the good folks at RunRev:
"If you own the engine
and don't like something in the engine,
change the engine."
:)
PS: Sorry about being over-sensitive about the "trolling" thing. I've
known you for enough years that I should have been able to expect
nothing more than good humor from you. I'd just had a complicated
morning; thank you for replying so gracefully.
