Stop infinite loop in AutoCAD using VsCode

carlos_m_gil_p — Sun, 10 Mar 2024 17:24:58 GMT

Hello boys how are you.
I wanted to ask if anyone knows how to get out of an infinite loop in AutoCAD using VsCode.
Today by mistake I was working with the while function and I did not set the condition for it to stop.
So it stayed in an infinite loop in autocad, I stopped debugging in vscode and nothing happened in autocad, I also closed vscode completely and the loop continued in autocad.
I tried with the escape key, enter, all possible but I couldn't stop the cycle, the only thing was to enter the application manager and forcefully close autocad.
If anyone knows a method to stop the loop, I would be grateful if you could tell me how to do it.
Greetings.

A google search said to try Shift+F5.

I just had same problem this morning, restarted 5 times, if there is lots of code in your loop so not obvious why its not working you can do say a X+1 if x= 1000 (EXIT), just put the increment X as part of a IF. The (EXIT) is a valid function and will do just that jump out of your lisp that is running, move the IF X till you find the spot that is not working.

Hello @leeminardi how are you.
I tried to do it with Shift+F5 and it didn't work, I don't know what other option it could be.

It only stops debugging in vscode.

Hello @Sea-Haven how are you.
Yes, it is a very good option, the problem is that I will have to do it whenever I do a while.
In this case, do not place the variable, that is, forget it. And then I couldn't get out of the loop.
That's why I was trying to find an option to stop the loop in AutoCAD.

Excuse my English, I only speak Spanish.

Thanks.

Hola @carlos_m_gil_p , I hope you are well.

Have you tried setting breakpoints at the while statements and check if the variables affecting the condition whether or not to continue the loop are changing as you think they should?

If I have knowledge about this topic, I also know how to work with while.
It was just an oversight, but I am left wondering, if it were to happen to me at some point, what I could do to resolve it.
Thanks for the contributions.

similar things also happen to me regularly.. i always have my vscode linked to my autocad session (F5). When it gets stuck in an infinite loop i just tap the reload button and that usually breaks out of the running lisps.

Yep can occur with lisp also and just use task manager to stop. Tried all the normals ESC CTrl+c Break and so on.

hm, maybe your VSC is not attached to AutoCAD correctly or its not setup correct?
I for example tried this loop and it breaks out as i said

(defun c:whilebreak (/ a) (setq a 0) (while t (setq a (1+ a)) ) )

Hello @EnM4st3r how are you.
Thanks for continuing to help.
In your example the while condition is T, which means that if you press ESC it will return NIL and stop it.
Try this example I show.

(defun c:xxx (/) (setq cont t) (while cont (if (and (not (vl-catch-all-error-p (setq pt (vl-catch-all-apply 'getpoint)))) (not (null pt))) (setq cont t))) (exit))

hm, that rly doesnt work with your example.. thought my example would be the same since hitting ESC also does not work for me with it. Maybe post an issue report here?
