You may be looking at B::Xref. It works well from the command line as: `perl -MO=Xref mytest.pl >mytest.xrf` [download] Dave	[reply] [d/l]

I'd better take a look at that too - in Sub::WrapPackages I have a horrible hack which uses a function from Pod::Coverage to figure out what is defined where. A function which is documented as being subject to future change. Thanks!	[reply]

You might also want to checkout Devel::TraceLoad if you want to find out what modules are loaded. `H:\Perl>perl -MDevel::TraceLoad p10.pl +strict.pm [from: p10.pl 1] +warnings.pm [from: p10.pl 2] +Data/Dumper.pm [from: p10.pl 3] +XSLoader.pm [from: C:/Perl/lib/Data/Dumper.pm 18] +Carp.pm [from: C:/Perl/lib/Data/Dumper.pm 21] +bytes.pm [from: C:/Perl/lib/Data/Dumper.pm 613] +Exporter.pm [from: C:/Perl/lib/Data/Dumper.pm 17] +overload.pm [from: C:/Perl/lib/Data/Dumper.pm 19] +warnings/register.pm [from: C:/Perl/lib/overload.pm 135]` [download] Update: I agree with davido that B::Xref is the way to go. _{janitored by ybiC: Fixed link to CPAN module - [cpan://Devel::Traceload]}	[reply] [d/l] [select]

A while ago, I was doing some refactoring where I needed a listing of all the subs and sub calls in a large program, which seems like almost what you want. I did a huge amount of searching through the Monestary. Here are some previous nodes that might be of help to you: Tabulate sub defs, sub calls in Perl code This seems to be the closes to what you want. It lists "(a) what subroutines are defined in each source file, and (b) what subroutine calls are issued from within each defined subroutine (or from the "main" portion of a given file)". However, I have had some problems with it complaining of syntax errors when there were none. YMMV. Generate a Graph-ical call tree for your *.pm perl modules This generates a tree of all your sub calls. However, it only registers calls that are made with an ampersand: ie. `&sub(@args)`. A reply toward the bottom of the thread suggests first running your code through B::Deparse because it outputs sub calls in this format. sub_graph.pl: perl call graph generator Note that I haven't tried any of these extensively. Good luck! Once it's Turing complete, everything else is just syntactic sugar.	[reply] [d/l]
