get the list of methods and variables

[v.muthukumaran]

Hi,

I have the child "child.pm" file. Inside this pm file it calls the parent packages with

use base parent.pm

From "parent.pm", it calls its parent packages with

use base grandparent.pm

Is there any way to get the all the methods and variables list to print from the child.pm

Regards
Muthu

Class::Inspector might also help.  For example:

#!/usr/bin/perl -l

package PkgA;

sub fooA {}
sub barA {}

package PkgB;

use base "PkgA";
sub fooB {}

package PkgC;

use base "PkgB";
sub barC {}


package main;

use Class::Inspector;

print for @{ Class::Inspector->methods('PkgC', 'full') };

__END__
PkgA::barA
PkgC::barC
PkgA::fooA
PkgB::fooB

Or, if you want to call it from within the child package (PkgC):

...
package PkgC;
...
use Class::Inspector;
print for @{ Class::Inspector->methods(__PACKAGE__, 'full') };

To get a list of methods and variables from child.pm, I would use Devel::Symdump. Here's an example:

#!/usr/bin/perl 

use strict;
use warnings;
use Data::Dumper::Concise;

require Devel::Symdump;

my @packs = qw(Data::Dumper::Concise);
my $obj   = Devel::Symdump->new(@packs);

my @array = $obj->scalars;
@array = $obj->arrays;
@array = $obj->hashes;

my $string = $obj->as_string;
print $string, "\n";

I substituted Data::Dumper::Concisefor Grandparent::Parent::Child; also, make sure that you "use" the package just below use warnings.

Depending on your needs, you may also find these threads helpful:

• Analyzing large Perl code base.
• Becoming familiar with a too-big codebase?

More such links are available at Reverse Engineering Stuff.

PAR installs the scandeps.pl program which can be called on any Perl file and it will list the dependencies.

You could take this dependency list and check for sub or (my|our|local) declarations, thus listing your methods and vars.

That's the first approach that comes to mind, (because I've been fiddling with PAR recently), hope it helps

scandeps lists modules/files, not methods/variables
