6 Data::Dump::Color - Like Data::Dump, but with color
7
9 This document describes version 0.241 of Data::Dump::Color (from Perl
10 distribution Data-Dump-Color), released on 2018-12-02.
11
13 Use it like you would Data::Dump, e.g.:
14
15 use Data::Dump::Color; dd localtime;
16
18 This module aims to be a drop-in replacement for Data::Dump. It adds
19 colors to dumps. It also adds various visual aids in the comments, e.g.
20 array/hash index, depth indicator, and so on.
21
22 For more information, see Data::Dump. This documentation explains
23 what's different between this module and Data::Dump.
24
26 By default Data::Dump::Color shows array index or hash pair sequence in
27 comments for visual aid, e.g.:
28
29 [
30 "this", # [0]
31 "is", # [1]
32 "a", # [2]
33 "5-element", # [3]
34 "array", # [4]
35 {
36 0 => "with", # .{0}
37 1 => "an", # .{1}
38 2 => "extra", # .{2}
39 3 => "hash", # .{3}
40 4 => "at", # .{4}
41 5 => "the", # .{5}
42 16 => "end", # .{6}
43 }, # [5]
44 ]
45
46 "[]" and "{}" brackets will indicate whether they are indexes to an
47 array or a hash. The dot prefixes will mark depth level.
48
49 To turn this off, set $INDEX to 0:
50
51 [
52 "this",
53 "is",
54 "a",
55 "5-element",
56 "array",
57 {
58 0 => "with",
59 1 => "an",
60 2 => "extra",
61 3 => "hash",
62 4 => "at",
63 5 => "the",
64 16 => "end",
65 },
66 ]
67
69 "$Data::Dump::*" package variables from Data::Dump, like
70 $Data::Dump::TRY_BASE64, etc are now in the "Data::Dump::Color"
71 namespace, e.g. $Data::Dump::Color::TRY_BASE64, etc.
72
73 Additional variables include:
74
75 $COLOR => BOOL (default: undef)
76 Whether to force-enable or disable color. If unset, color output
77 will be determined from $ENV{COLOR} or when in interactive terminal
78 (when "-t STDOUT" is true).
79
80 %COLORS => HASH (default: default colors)
81 Define colors.
82
83 $INDEX => BOOL (default: 1)
84 Whether to add array/hash index visual aid.
85
86 $LENTHRESHOLD => int (default: 500)
87 Add string length visual aid for hash key/hash value/array element
88 if length is at least this value.
89
91 How do I turn off index comments?
92 Set $Data::Dump::Color::INDEX to 0.
93
94 How do I turn off colors?
95 Well, colors is sort of the point of this module. But if you want to
96 turn it off, you can set environment COLOR to 0, or
97 $Data::Dump::Color::COLOR to 0.
98
99 How do I customize colors?
100 Fiddle the colors in %Data::Dump::Color::COLORS. There will probably be
101 proper color theme support in the future (based on
102 SHARYANTO::Role::ColorTheme.
103
105 · NO_COLOR
106
107 Can be used to disable color. Takes precedence over the "COLOR"
108 environment. See <https://no-color.org> for more details.
109
110 · COLOR
111
112 If set, then will force color output on or off. By default, will
113 only output color when in interactive terminal. This is consulted
114 when $COLOR is not set.
