tidy_json
A mixin providing (recursive) JSON serialization and pretty printing.
Installation
$ gem install tidy_json
Or, in your Gemfile
:
source 'https://rubygems.org'
# ...
gem 'tidy_json'
# ...
Formatting Options
As of version 0.3.0, most of the same options accepted by JSON.generate
can be passed to #write_json
, #to_tidy_json
, or TidyJson.tidy
.
See the docs for a current list of options and their default values.
Example
require 'tidy_json'
class Jsonable
attr_reader :a, :b
def initialize
@a = { a: 'uno', f: ['I', 'II', 'III', ['i.', 'ii.', 'iii.', { 'ichi': "\u{4e00}", 'ni': "\u{4e8c}", 'san': "\u{4e09}", 'yon': "\u{56db}" }]], c: {}, b: 'dos', e: [[]] }
@b = { z: { iv: 4, ii: 'dos', iii: 3, i: 'uno' }, b: ['deux', 3, '<abbr title="four">IV</abbr>'], a: 1, g: [{ none: [] }], f: %w[x y z] }
end
end

Command Line Usage
After installing the gem, pass the name of a file containing JSON to jtidy
(with or without a file extension). Run jtidy -h
for a complete list of
formatting options:
jtidy FILE[.json] [-d out[.json]] [-i [2,4,6,8,10,12]] [-p [1..8]] [-v [1..8]] [-o D] [-a D] [-m N] [-e] [-A] [-N] [-s] [-f] [-P]
-d, --dest out[.json] Name of output file
-i, --indent [2,4,6,8,10,12] The number of spaces to indent each object member [2]
-p, --prop-name-space [1..8] The number of spaces to put after property names [0]
-v, --value-space [1..8] The number of spaces to put before property values [1]
-o, --object-delim D A string of whitespace to delimit object members [\n]
-a, --array-delim D A string of whitespace to delimit array elements [\n]
-m, --max-nesting N The maximum level of data structure nesting in the generated JSON; 0 == "no depth checking" [100]
-e, --escape Escape /'s [false]
-A, --ascii Generate ASCII characters only [false]
-N, --nan Allow NaN, Infinity and -Infinity [false]
-s, --sort Sort property names [false]
