NAME¶
Devel::CallTrace - See what your code's doingSYNOPSIS¶
#!/usr/bin/perl -d:CallTrace package foo; sub bar {print "bar\n";
baz(); } sub baz {
print "boo\n"; } foo::bar();
RATIONALE¶
There are a number of perl modules in the CPAN that are designed to trace a program's execution as it runs. Each uses a different trick to do its job, but none of them quite met my needs. The technique this module uses is quite simple and seems to be quite robust.DB::sub¶
perl will automatically call DB::sub on each subroutine call and leave it up to us to dispatch to where we want to go.Devel::CallTrace::called¶
This routine is called with two parameters:- DEPTH
- The integer "depth" that this call is being called at.
- PARAMS
- A reference to the routine's @INC
BUGS¶
It uses the debugger. How could it not have bugs?SEE ALSO¶
perldebguts, DB, a licensed therapist. trace - Uses source filters. Scares me. Devel::TraceCalls - Very robust API. The code seems to do all sorts of scary magic Debug::Trace - Uses symbol table magic to wrap your functions. Devel::TRaceFuncs - Requires developers to instrument their source files.COPYRIGHT¶
