=head1 NAME

Devel::REPL::Plugin::DataPrinter - Format REPL results with Data::Printer

=head1 VERSION

version 0.005

=head1 SYNOPSIS

In your re.pl config file (usually C<< ~/.re.pl/repl.rc >>):

    load_plugin('DataPrinter');

That's about it. Your re.pl should now give you nicer outputs :)

=head1 CUSTOMIZATION

This plugin also provides a method C<dataprinter_config>, which can
be used to configure L<Data::Printer> for use in L<Devel::REPL>.  For example,
if you don't care for colored output:

    $_REPL->dataprinter_config({
      colored => 0,
    });

Or if you ask for caller_info in your .dataprinter file, but don't want it in
the REPL:

    $_REPL->dataprinter_config({
      caller_info => 0,
    });

See L<Data::Printer/Customization> for configuration options; the values
provided to C<dataprinter_config> override your .dataprinterrc.  C<colored> is
on by default, and the only settings you may not override are
C<use_prototypes> and C<return_value>.  Note that C<dataprinter_config> only
applies to the printing that the REPL does; if you invoke C<p()> in your REPL
session yourself, these settings are B<not> applied.

=head2 Devel::REPL::Plugin::DataPrinter specific customization

=over

=item stringify

If the reference being printed has a stringification overloaded method and you
do not want to use it by default, you can configure an override by setting the
package to zero:

    $_REPL->dataprinter_config({
      stringify => {
        'DateTime' => 0,
      },
    });
