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.
my $data = get_some_data_from_somewhere(); ... use DDP; p $data; # <-- pretty-prints $data's content to STDERR
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 4 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. 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.
output to many different targets like files, variables or open handles (defaults to STDERR)
keep your customized settings on a
.dataprinterfile that allows different options per module being analyzed!
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.
