To see what’s inside a variable or a Perl object, Data::Dumper is often used.
For inspecting objects, its features are limited.
Data::Printer helps you dump your Perl data structures in a complete, colored and human-friendly way.
This module is not part of the Perl core modules.
To install it on Debian Buster :
apt install libdata-printer-perl
Start using it. Its syntax is simple and pretty straightforward.
For objects, it provides public/private methods details that Data::Dumper does not.
