NAME DD - Dump data structure for debugging VERSION This document describes version 0.002 of DD (from Perl distribution DD), released on 2019-08-01. SYNOPSIS In your code: use DD; # exports dd() and dmp() ... dd $data; # prints data to STDOUT ... my $foo = dd $data; # prints data to STDOUT, also returns it so $foo gets assigned On the command-line: % perl -MDD -E'...; dd $data; ...' DESCRIPTION "DD" is a module with a short name you can use for debugging. It provides "dd()" which dumps data structure to STDOUT, as well as return the original data so you can insert "dd" in the middle of expressions. "DD" can use several kinds of backends. The default is Data::Dump which is chosen because it's a mature module and produces visually nice dumps for debugging. You can also use these other backends: * Data::Dumper * Data::Dump::Color Optional dependency. * Data::Dmp Optional dependency. PACKAGE VARIABLES $BACKEND The backend to use. The default is to use "PERL_DD_BACKEND" environment variable or "Data::Dump" as the fallback default. FUNCTIONS dd dmp ENVIRONMENT PERL_DD_BACKEND Can be used to set the default backend.

BUGS Please report any bugs or feature requests on the bugtracker website When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature. SEE ALSO XXX - basically the same thing but with a different name and defaults. I happen to use "XXX" to mark todo items in source code, so I prefer "DD" instead.
