Class Browser for Perl

[saragwyn]

Hi all -

I've been Googling myself silly trying to find an IDE or other tool that allows one to navigate up and down a class hierarchy for a Perl project (for Linux).

The only thing we have found is Perly-Sense, which is an Emacs plug in and not as GUI friendly as we would like. That plug in does allow one to jump to base class methods overridden in the child class and lists the parents of a derived class.

Apps that have 'Code Browsing' do not necessarily support this feature (such as Komodo or Eclipse with EPIC).

I have consulted the spreadsheet on Perl tools that is posted on Perl Monks, but it does not call out that feature specifically.

Thanks

If no existing tools have that feature, you could try something like Padre, which have this feature in their TODO list. I don't think it's done yet, but maybe you could help/encourage them to work on that feature next?

Parsing Perl files located in subdirectories of a particular directory might be fairly straightforward (with the caveat that only perl can parse Perl): you can find Perl files using File::Find, and then parse them with adamk's excellent PPI. Visualizing it and plugging it into Padre will be the (only!) hard bits.

Your help in adding such capabilities to Padre is surely welcome!

I had actually perused the thread referred to in the last post, and it mainly contains references to visualization tools and not code editing/browsing tools.

Another dependency-list tool - and not really a gui - is scandeps.pl from Module::ScanDeps, which is used in PAR-Packer.
For example I use

scandeps.pl $(perldoc -l CGI)

on my commandline to find CGI module-dependencies and perldoc -m CGI to list contents of a module, here CGI.

My guess is that you can get some of what you want with Exhuberant Ctags. I use the Exhuberant Ctags plugin for vim, and it displays a very readable structured view. A project I discovered called "inheritanCe" attempts to leverage this for what it sounds like you want. It might not be as IDE-y as you want, but it's a start.

Has anyone used Perl::Tags with vim? Does it provide class browsing?

For inspecting module subs and class methods, I use Class::Inspector in a script like so:

#!/usr/bin/perl
use strict;
use warnings;
use Class::Inspector;
use English qw( -no_match_vars );

for my $class_name ( @ARGV ) {
    chomp $class_name;
    print "$class_name:\n";
    eval {
        eval "require $class_name";
    };
    if ( $EVAL_ERROR ) {
        print "Unable to load class $class_name! ($EVAL_ERROR)\n";
        next;
    }

    my $method_names_ref = Class::Inspector->methods( $class_name, 'full' );
    if ( !defined $method_names_ref ) {
        print "No methods for class $class_name!\n";
        next;
    }

    my @method_names = @{ $method_names_ref };
    for my $method_name ( sort @method_names ) {
        print "\t$method_name\n";
    }
}
