Data::Printer

Data::Printer is a Perl module to pretty-print Perl data structures and objects in full color, in a way that is properly formatted to be inspected by a human.

Basic Usage:

    my $data = get_some_data_from_somewhere();
    ...
    use DDP; p $data;  # <-- pretty-prints $data's content to STDERR

See Data::Printer in action

Main features:

Variable dumps designed for easy parsing by the human brain, not a machine;
Highly customizable, from indentation size to depth level. You can even rename the exported p() function!
Beautiful (and customizable) colors to highlight variable dumps and make issues stand-out quickly on your console. Comes bundled with several themes for you to pick.
Filters for specific data structures and objects to make debugging much, much easier. Includes filters for several popular classes from CPAN like JSON::*, URI, HTTP::*, LWP, Digest::*, DBI and DBIx::Class, printing what really matters to developers debugging code. It also lets you create your own custom filters easily.
Lets you inspect information that's otherwise difficult to find/debug in Perl 5, like circular references, reference counting (refcount), weak/read-only information, even estimated data size - all to help you spot issues with your data like leaks without having to know a lot about internal data structures or install heavy-weight tools like Devel::Gladiator.
keep your custom settings on a .dataprinter file that allows different options per module being analyzed! You may also create a custom profile class with your preferences and filters and upload it to CPAN.
output to many different targets like files, variables or open handles (defaults to STDERR). You can send your dumps to the screen or anywhere else, and customize this setting on a per-project or even per-module basis, like print everything from Some::Module to a debug.log file with extra info, and everything else to STDERR.
Easy to learn, easy to master. Seriously, what you already know cover about 90% of all use cases.
Works on Perl 5.8 and later Because you can't control where you debug, we try our best to be compatible with all versions of Perl 5.
Best of all? No non-core dependencies, Zero. Nada. so don't worry about adding extra weight to your project, as Data::Printer can be easily added/removed.
