Stopping debugger when loop reaches nth iteration

[MJLM]

Hello.

 

Can somebody tell me whether the visual lisp debugger supports braking based on a conditional criterion? Say I want to break when the counter of a loop running reaches the nth iteration.

 

Thanks

You could build it into your lisp.

 

(setq i 0)
(setq rep "Yes")
(while (eq rep "Yes")
  
  ;code you want to loop

  (setq i (1+ i))
  (if (> i 500)      ;check to continue every 500 loops
    (progn
      (setq i 0)
      (initget "Yes No")
      (setq rep
        (cond
          ((getkword "\nContinue? [Yes/No]: ")) ( "Yes")
        )
      )
    )
  )
)

Thanks but I want the debugger to let me continue with inspection of the code while running by using (shift+) F8, animate etc...

I guess this is not really an option with VL IDE like for instance Visual studio, right?

IDK use BricsCAD

Take a look at this code. Click on the end of the indicated lines, next to the last ")" then press F9 to set the breakpoint.

Then run the code and when it stops, press ctrl+F8 to continue.

(setq i 1 s 0)
(while (<= i 20)
  (setq s (+ s i))
  (setq i (1+ i))
  (cond
    ((= i 10)
      (princ "\nFirst stop");<-- Breakpoint
    )
    ((= i 15)
     (princ "\nSecond stop");<-- Breakpoint
    )
  )
)

Following all steps above, this is what I got on the console

0 
First stop
_1_$ 

Second stop
_1_$ 

nil 
_$ i s
21
210
_$
