Data::Printer::ProfileUser)Contributed Perl DocumenData::Printer::Profile(3pm)

NAME
       Data::Printer::Profile - customize your Data::Printer with code

SYNOPSIS
           package Data::Printer::Profile::MyProfile;

           sub profile {
               return {
                   show_tainted => 1,
                   show_unicode => 0,
                   array_max    => 30,

                   # ...and so on...
               }
           }
           1;

       Then put in your '.dataprinter' file:

           profile = MyProfile

       or load it at compile time:

           use DDP profile => 'MyProfile';

       or anytime during execution:

           p $some_data, profile => 'MyProfile';

DESCRIPTION
       Usually a ".dataprinter" file is enough to customize Data::Printer. But
       sometimes you want to use actual code to create special filters and
       rules, like a dynamic color scheme depending on terminal background or
       even the hour of the day, or a custom message that includes the
       hostname. Who knows!

       Or maybe you just want to be able to upload your settings to CPAN and
       load them easily anywhere, as shown in the SYNOPSIS.

       For all those cases, use a profile class!

   Creating a profile class
       Simply create a module named "Data::Printer::Profile::MyProfile"
       (replacing, of course, "MyProfile" for the name of your profile).

       That class doesn't have to inherit from "Data::Printer::Profile", nor
       add Data::Printer as a dependency. All you have to do is implement a
       subroutine called "profile()" that returns a hash reference with all
       the options you want to use.

   Load order
       Profiles are read first and expanded into their options. So if you have
       a profile called MyProfile with, for example:

           show_tainted = 0
           show_lvalue  = 0

       And your ".dataprinter" file contains something like:

           profile     = MyProfile
           show_lvalue = 1

       The specific 'show_lvalues = 1' will override the other setting in the
       profile and the final outcome will be as if your setup said:

           show_tainted = 0
           show_lvalue  = 1

       However, that is of course only true when the profile is loaded
       together with the other settings. If you set a profile later, for
       instance as an argument to "p()" or "np()", then the profile will
       override any previous settings - though it will still be overriden by
       other inline arguments.
