Tracing Subs

[Sharad Gupta]

Hi All,

I have a bunch of scripts which calls a sub from a module, and that module in turn would call another sub from someone else and so on. Skimming through them is driving me crazy.

Is there a way i can trace the calling of the routines till N levels.


TIA,
-Sharad

I think this too will not help you much since you dont seem to know what
routine is being called

But What is the bigger Idea, Why do you want to know which modules are
being called.
for eg. When I do a readdir(DIR) , and it gives me What I need , Why am
I bothered what modules does readdir use

The bigger idea is:

I am trying to understand how some of the scripts work.

Now the scripts call some *inhouse* nested subroutine calls. I want to see which routine calls what and try to read them to get a better idea of what they are doing.

I want to rearrange them from this crazy design.

I think you might like Devel::TraceSubs from CPAN and PPM.

Using the caller() function, you can create your own stack trace.

perldoc -f caller
