JS Is there a way to abort endless loops?

[moniuch]

Shame on me, but this happens. Ienter an endless loop and the whole computer is spinning off. If I kill the process, I'll lose unsaved changes. Is there any [poor] developer interrupt key to press to kill running scripts in ESTK2?

[Plus, I'd gladly see document recovery, oh well...]

I don't think you can stop a running JavaScript except by closing the application. What you can do is to add an artificial upper limit, so let's say you have a while loop,

while (condition) { /*do something*/ }

Then you can change it to:
var i=0;
while (condition && i<1000000) { /*do something*/; i++;}
if (i==1000000) { /* Present some error message */ }

It's not the best solution in the world, but it will at least guarantee that you won't get into an endless loop.

Another option, use $.bp(condition);
If condition is true, the script stops.

That's some workaround, thanks. Although I'd welcome an environment shortcut.

I found that when I'm testing a script for Adobe apps, it helps to have an alerts within such a loop. Even though one may call it a "crude debug", when a prompt comes up within Adobe app, I am able to switch to ESTK and press stop. That saves the butt too.

I've never tried with Illustrator, but in InDesign the escape key will
break out of a script.
