in reply to (Debugging, Tracing, Trace, Instrumenting) Automatic tracing of my Perl code?

Why do you want to do this? If you're looking to trace the program flow, check out the built-in debugger. You can step through your program, set breakpoints on lines, subroutines, and conditionals. You can also print stack backtraces and print complex data structures on the fly to verify that they're correct.

I suspect that a lot of people overlook the usefulness of the debugger as many questions that are answered here would quickly be resolved with a quick debugger session.

Check it out. It will quickly become your best friend. And yes, if you step through your program, it will automatically say what line the program is on at all times :) In fact, everything that you describe in your title is contained in the debugger.

    I have to agree with Ovid. As with everything else, why reinvent the wheel? Not only does the build-in debbuger work very well, its already there.

    I'm on Win32, so I decided to give ActiveState's debugger a shot, and I have found it not only to be a solid app, but a very very useful tool while trying to figure where things went sour in my apps.

    The idea of printing line by line does sound like a cool challenge though, but only as one of those I-wonder-if-this-can-be-done? things...
