How to get Exception.printStackTrace output to print to console/terminal

RxC over 1 year ago

Apology for this very basic question - but how do i get Execption.printStackTrace to be printed in the console/terminal ?

I mostly need that for debugging purposes, e.g. when I want to identify a specific code-flow to a commonly used function,

and with Java I would simply add the following line to the commonly-used-function code:

new Exception().printStackTrace()

however when i try that with ConnectIQ/MonkeyC nothing gets printed to the console/terminal (when run on sim)

p.s. I am aware of and use the VisualStudio debugger, but sometimes the use of the exception stacktrace is quicker and simpler for a quick troubleshooting

It should go to the console, similar to System.println

does it work for you ? i.e. do you see stacktraces when you run new Exception().printStackTrace() ?

Yes, but not what you think: it only becomes "stack" when you throw it, not when you create it:

        try {
            var ee = new Exception();
            System.println("try:");
            ee.printStackTrace();
            throw ee;
        } catch (e) {
            System.println("catch:");
            e.printStackTrace();
        }

output:

try:
catch:

Stack:
 ....
