Devel::Carnivore

Details

Devel::Carnivore 0.09 is libraries software developed by Malte Ubl.
Devel::Carnivore is a Perl module to spy on your hashes (and objects).



SYNOPSIS

use Devel::Carnivore;

sub new_attribute {
my %self : Watch("myName") = ();

bless %self, shift;
}

sub new_functional {
my $self = {};
watch $self, "myName";
bless $self
}

sub new_blessed {
my $self = {};
bless $self;
watch $self, "myName";
return $self;
}

sub new_scalar_attribute {
my $self : Watch("myName") = {};
bless $self
}

This module allows you to debug your hashes and, in particular, your objects based on hashes without using the perl debugger. There are several good reasons to do this. Among them:

1) You're too stupid to use the perl debugger (This is true for me)

2) You're building web applications and the perl debugger doesn't work very well in that environment

Obviously, this module does not provide you with a complete debugger. All it does is helping you keep track of the state changes which occur to your objects.

Output

By default all output is written to STDERR. You may change this behavior by assigning a valid output filehandle to $Devel::Carnivore::OUT.

Everytime the hash which is being watched by this module is assigned to, a message like this is created: > ProgLang: "cool" changed from "Java" to "Perl" at devel.pl line 30

So what does this tell you?

You have a Perl file named devel.pl. On line 30 your code changed the value of the key "cool" from "Java" to "Perl". In order, to identify this hash you optionally named it "ProgLang".

Requirements:
Perl
Devel::Carnivore 0.09 supports english interface languages and works with Linux.

Downloading Devel::Carnivore 0.09 will take several seconds if you use fast ADSL connection.
