how to list all loaded modules of a perl program

[Fei Liu]

Hi group, is it possible to list all loaded modules of a perl program?
For example, the perl application could have a very complicated
hierarchy of module structure where each module load different modules
on their own:

i.e
package main
use A;
use C;

package A
use B;

package C
use D;

package B
use BA;
use BB;

package D;
use DA;
use DB;
use DC;

package DA
use DAA;
use DAB;

etc, etc.

Now is it possible within the main program to list all the preloaded
modules via use statement? It's possible to do this by using a parser
to recursively parse through modules with a predefined level, but
idealy a in program complete list could be better.

Please let me know if there is an existing solution for this problem,
thanks!

At any time in a program you may print the contents of %INC, which
will tell you what modules are loaded.

If you want to know every module ever loaded, use an end block, such
as:

END {
print Dumper \%INC;
}


If you wish to know how much time your program spent inside of each
method of each module:

perl -drofile whatever.pl
