Can i stop the execution of Blockly using JSInterpreter?

[whaletalent]

Hello! I wonder if I can create a function that cancels Blockly's step-by-step execution. I'm using JS Interpreter to run custom blocks and it's working perfectly, however, on very long runs, I'd like to cancel execution if possible. How I do a function to cancel the stepInterpreter?

Neil may follow up with another suggestion, but we recommending throwing for infinite loops to break out of execution.

Cheers,

Erik

I'll assume that you have the following code or something like it somewhere in your program:

function nextStep() {
  if (myInterpreter.step()) {
    window.setTimeout(nextStep, 10);
  }
}

Just keep a record of the timeout's process ID:

var pid = 0;
function nextStep() {
  if (myInterpreter.step()) {
    pid = window.setTimeout(nextStep, 10);
  }
}

Then whenever you want to terminate the execution, call:

window.clearTimeout(pid);

TY for help guys! And a special thank you again for Neil, my savior! I've tried everything, except use clearTimeout() function. Sorry for this silly question, you helped me a lot!
