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.
