Implement debugger command to skip expression execution

Post #1 of 4 (176 views)

Hello Perl5-porters,

1. Here is a problem
Time to time while debugging I want to skip function execution without restarting application.

line 1: some_code();
line 2: # I reach function I do not want to be called:
line 3: this_should_not_be_called();
line 4: next

2. Here is the syntax that I'm proposing
Would be very helpful if I could run some 'goto line4' command to skip expression execution at line 3.

3. Here are the benefits of this
This will save huge of time, becaue I will not stop debugging, comment out line 3 and start application and debugging from begining.

4. Here are potential problems
None.

Thanks.

Doesn't that just break at that line if the condition is true, not actually
skip the line?

I was looking through the POD and I didn't find anything that would help
the OP with that exact request.

You're right. I misunderstood it as asking to "skip over" in terms of debug flow. Those commands do indeed not help there.
