NAME

6       JSON::Color - Encode to colored JSON
7

VERSION

9       This document describes version 0.130 of JSON::Color (from Perl
10       distribution JSON-Color), released on 2020-06-09.
11

SYNOPSIS

13        use JSON::Color qw(encode_json);
14        say encode_json([1, "two", {three => 4}]);
15

DESCRIPTION

17       This module generates JSON, colorized with ANSI escape sequences.
18
19       To change the color, see the %theme in the source code. In theory you
20       can also modify it to colorize using HTML.
21

FUNCTIONS

23   encode_json($data, \%opts) => STR
24       Encode to JSON. Will die on error (e.g. when encountering non-
25       encodeable data like Regexp or file handle).
26
27       Known options:
28
29       •   color_theme => STR
30
31           Pick a color theme, which is a ColorTheme-confirming color theme
32           module. The default is JSON::Color::ColorTheme::default. For
33           example: ColorTheme::Lens::Lighten
34
35       •   pretty => BOOL (default: 0)
36
37           Pretty-print.
38
39       •   linum => BOOL (default: 0)
40
41           Show line number.
42
43       •   sort_by => CODE
44
45           If specified, then sorting of hash keys will be done using this
46           sort subroutine.  This is similar to the "sort_by" option in the
47           JSON module. Note that code is executed in "JSON::Color" namespace,
48           example:
49
50            # reverse sort
51            encode_json(..., {sort_by => sub { $JSON::Color::b cmp $JSON::Color::a }});
52
53           Another example, using Sort::ByExample:
54
55            use Sort::ByExample cmp => {-as => 'by_eg', example => [qw/foo bar baz/]};
56            encode_json(..., {sort_by => sub { by_eg($JSON::Color::a, $JSON::Color::b) }});

FAQ

59   What about loading?
60       Use JSON.
61
62   How to handle non-encodeable data?
63       Use Data::Clean::JSON.
64
65   Why do numbers become strings?
66       Example:
67
68        % perl -MJSON::Color=encode_json -E'say encode_json([1, "1"])'
69        ["1","1"]
70
71       To detect whether a scalar is a number (e.g. differentiate between "1"
72       and 1), the XS module Scalar::Util::LooksLikeNumber is used. This is
73       set as an optional prerequisite, so you'll need to install it
74       separately. After the prerequisite is installed:
75
76        % perl -MJSON::Color=encode_json -E'say encode_json([1, "1"])'
77        [1,"1"]
78

ENVIRONMENT

80   JSON_COLOR_COLOR_THEME
81       Set default color theme. Has precedence over "COLOR_THEME".
82
83   COLOR_THEME
84       Set default color theme.

SEE ALSO

101       To colorize with HTML, you can try Syntax::Highlight::JSON.
102
103       Syntax::SourceHighlight can also colorize JSON/JavaScript to HTML or
104       ANSI escape. It requires the GNU Source-highlight library.
