NAME

Data::Printer::Theme - create your own color themes for DDP!

SYNOPSIS

package Data::Printer::Theme::MyCustomTheme;

sub colors {
    return {
        array       => '#aabbcc', # array index numbers
        number      => '#aabbcc', # numbers
        string      => '#aabbcc', # strings
        class       => '#aabbcc', # class names
        method      => '#aabbcc', # method names
        undef       => '#aabbcc', # the 'undef' value
        hash        => '#aabbcc', # hash keys
        regex       => '#aabbcc', # regular expressions
        code        => '#aabbcc', # code references
        glob        => '#aabbcc', # globs (usually file handles)
        vstring     => '#aabbcc', # version strings (v5.30.1, etc)
        lvalue      => '#aabbcc', # lvalue label
        format      => '#aabbcc', # format type
        repeated    => '#aabbcc', # references to seen values
        caller_info => '#aabbcc', # details on what's being printed
        weak        => '#aabbcc', # weak references flag
        tainted     => '#aabbcc', # tainted flag
        unicode     => '#aabbcc', # utf8 flag
        escaped     => '#aabbcc', # escaped characters (\t, \n, etc)
        brackets    => '#aabbcc', # (), {}, []
        separator   => '#aabbcc', # the "," between hash pairs, array elements, etc
        quotes      => '#aabbcc', # q(")
        unknown     => '#aabbcc', # any (potential) data type unknown to Data::Printer
    };
}
1;

Then in your .dataprinter file:

theme = MyCustomTheme

That's it! Alternatively, you can load it at runtime:

use DDP theme => 'MyCustomTheme';

DESCRIPTION

Data::Printer colorizes your output by default. Originally, the only way to customize colors was to override the default ones. Data::Printer 1.0 introduced themes, and now you can pick a theme or create your own.

Data::Printer comes with several themes for you to choose from:

Run examples/try_me.pl to see them in action on your own terminal!

CREATING YOUR THEMES

A theme is a module in the Data::Printer::Theme namespace. It doesn't have to inherit or load any module. All you have to do is implement a single function, colors, that returns a hash reference where keys are the expected color labels, and values are the colors you want to use.

Feel free to copy & paste the code from the SYNOPSIS and customize at will :)

Customizing Colors

Setting any color to undef means "Don't colorize this". Otherwise, the color is a string which can be one of the following:

Named colors, Term::ANSIColor style (discouraged)

Only 8 named colors are supported:

black, red, green, yellow, blue, magenta, cyan, white

and their bright_XXX, on_XXX and on_bright_XXX variants.

Those are provided only as backards compatibility with older versions of Data::Printer and, because of their limitation, we encourage you to try and use one of the other representations.

SGR Escape code (Terminal style)

You may provide any SGR escape sequence, and they will be honored as long as you use double quotes (e.g. "\e[38;5;196m"). You may use this to achieve extra control like blinking, etc. Note, however, that some terminals may not support them.

An RGB value in one of those formats (Recommended)

'rgb(0,255,30)'
'#00FF3B'

NOTE: There may not be a real 1:1 conversion between RGB and terminal colors. In those cases we use approximation to achieve the closest option.

PUBLIC INTERFACE

This module is not meant for public use. The following documentation is mostly for developers of Data::Printer itself.

  • new( %params ) - creates a new theme object

    my $theme = Data::Printer::Theme->new(
    name            => 'Material',
    color_level     => 1,
    color_overrides => { ... },
);

  • name - displays the theme name.

  • customized - true if theme has at least one color override.

  • color_for( $label ) - displays the color as-is.

  • sgr_color_for( $label ) - prints the SGR (terminal) color modifier.

  • color_reset - prints the SGR (terminal) color reset modifier.
