SYNOPSIS

9           package Data::Printer::Theme::MyCustomTheme;
10
11           sub colors {
12               return {
13                   array       => '#aabbcc', # array index numbers
14                   number      => '#aabbcc', # numbers
15                   string      => '#aabbcc', # strings
16                   class       => '#aabbcc', # class names
17                   method      => '#aabbcc', # method names
18                   undef       => '#aabbcc', # the 'undef' value
19                   hash        => '#aabbcc', # hash keys
20                   regex       => '#aabbcc', # regular expressions
21                   code        => '#aabbcc', # code references
22                   glob        => '#aabbcc', # globs (usually file handles)
23                   vstring     => '#aabbcc', # version strings (v5.30.1, etc)
24                   lvalue      => '#aabbcc', # lvalue label
25                   format      => '#aabbcc', # format type
26                   repeated    => '#aabbcc', # references to seen values
27                   caller_info => '#aabbcc', # details on what's being printed
28                   weak        => '#aabbcc', # weak references flag
29                   tainted     => '#aabbcc', # tainted flag
30                   unicode     => '#aabbcc', # utf8 flag
31                   escaped     => '#aabbcc', # escaped characters (\t, \n, etc)
32                   brackets    => '#aabbcc', # (), {}, []
33                   separator   => '#aabbcc', # the "," between hash pairs, array elements, etc
34                   quotes      => '#aabbcc', # q(")
35                   unknown     => '#aabbcc', # any (potential) data type unknown to Data::Printer
36               };
37           }
38           1;
39
40       Then in your ".dataprinter" file:
41
42           theme = MyCustomTheme
43
44       That's it! Alternatively, you can load it at runtime:
45
46           use DDP theme => 'MyCustomTheme';
47

DESCRIPTION

49       Data::Printer colorizes your output by default. Originally, the only
50       way to customize colors was to override the default ones. Data::Printer
51       1.0 introduced themes, and now you can pick a theme or create your own.
52
53       Data::Printer comes with several themes for you to choose from:
54
55       •   Material (the default)
56
57       •   Monokai
58
59       •   Solarized
60
61       •   Classic (original pre-1.0 colors)
62
63       Run "examples/try_me.pl" to see them in action on your own terminal!
64

CREATING YOUR THEMES

66       A theme is a module in the "Data::Printer::Theme" namespace. It doesn't
67       have to inherit or load any module. All you have to do is implement a
68       single function, "colors", that returns a hash reference where keys are
69       the expected color labels, and values are the colors you want to use.
70
71       Feel free to copy & paste the code from the SYNOPSIS and customize at
72       will :)
73
74   Customizing Colors
75       Setting any color to "undef" means "Don't colorize this".  Otherwise,
76       the color is a string which can be one of the following:
77
78       Named colors, Term::ANSIColor style (discouraged)
79
80       Only 8 named colors are supported:
81
82       black, red, green, yellow, blue, magenta, cyan, white
83
84       and their "bright_XXX", "on_XXX" and "on_bright_XXX" variants.
85
86       Those are provided only as backards compatibility with older versions
87       of Data::Printer and, because of their limitation, we encourage you to
88       try and use one of the other representations.
89
90       SGR Escape code (Terminal style)
91
92       You may provide any SGR escape sequence, and they will be honored as
93       long as you use double quotes (e.g. "\e[38;5;196m"). You may use this
94       to achieve extra control like blinking, etc. Note, however, that some
95       terminals may not support them.
96
97       An RGB value in one of those formats (Recommended)
98
99           'rgb(0,255,30)'
100           '#00FF3B'
101
102       NOTE: There may not be a real 1:1 conversion between RGB and terminal
103       colors. In those cases we use approximation to achieve the closest
104       option.
