# 
# # JavaScript Object Notation (JSON)
#
# JSON is a lightweight data-interchange format.
#
# A JSON value is one of the following:
# *   Double-quoted text:  `"foo"`.
# *   Number:  `1`, `1.0`, `2.0e2`.
# *   Boolean:  `true`, `false`.
# *   Null: `null`.
# *   Array: an ordered list of values, enclosed by square brackets:
#         ["foo", 1, 1.0, 2.0e2, true, false, null]
#
# *   Object: a collection of name/value pairs, enclosed by curly braces; each
#     name is double-quoted text; the values may be any JSON values:
#         {"a": "foo", "b": 1, "c": 1.0, "d": 2.0e2, "e": true, "f": false, "g": null}
#
#
# A JSON array or object may contain nested arrays, objects, and scalars to any
# depth:
#     {"foo": {"bar": 1, "baz": 2}, "bat": [0, 1, 2]}
#     [{"foo": 0, "bar": 1}, ["baz", 2]]
#
# ## Using Module JSON
#
# To make module JSON available in your code, begin with:
#     require 'json'
#
# All examples here assume that this has been done.
#
# ### Parsing JSON
#
# You can parse a String containing JSON data using either of two methods:
# *   `JSON.parse(source, opts)`
# *   `JSON.parse!(source, opts)`
#
#
# where
# *   `source` is a Ruby object.
# *   `opts` is a Hash object containing options that control both input allowed
#     and output formatting.
#
#
# The difference between the two methods is that JSON.parse! omits some checks
# and may not be safe for some `source` data; use it only for data from trusted
# sources. Use the safer method JSON.parse for less trusted sources.
#
# #### Parsing JSON Arrays
#
# When `source` is a JSON array, JSON.parse by default returns a Ruby Array:
#     json = '["foo", 1, 1.0, 2.0e2, true, false, null]'
#     ruby = JSON.parse(json)
#     ruby # => ["foo", 1, 1.0, 200.0, true, false, nil]
#     ruby.class # => Array
#
# The JSON array may contain nested arrays, objects, and scalars to any depth:
#     json = '[{"foo": 0, "bar": 1}, ["baz", 2]]'
#     JSON.parse(json) # => [{"foo"=>0, "bar"=>1}, ["baz", 2]]
#
# #### Parsing JSON Objects
#
# When the source is a JSON object, JSON.parse by default returns a Ruby Hash:
#     json = '{"a": "foo", "b": 1, "c": 1.0, "d": 2.0e2, "e": true, "f": false, "g": null}'
#     ruby = JSON.parse(json)
#     ruby # => {"a"=>"foo", "b"=>1, "c"=>1.0, "d"=>200.0, "e"=>true, "f"=>false, "g"=>nil}
#     ruby.class # => Hash
#
# The JSON object may contain nested arrays, objects, and scalars to any depth:
#     json = '{"foo": {"bar": 1, "baz": 2}, "bat": [0, 1, 2]}'
#     JSON.parse(json) # => {"foo"=>{"bar"=>1, "baz"=>2}, "bat"=>[0, 1, 2]}
#
# #### Parsing JSON Scalars
#
# When the source is a JSON scalar (not an array or object), JSON.parse returns
# a Ruby scalar.
#
# String:
#     ruby = JSON.parse('"foo"')
#     ruby # => 'foo'
#     ruby.class # => String
#
# Integer:
#     ruby = JSON.parse('1')
#     ruby # => 1
#     ruby.class # => Integer
#
# Float:
#     ruby = JSON.parse('1.0')
#     ruby # => 1.0
#     ruby.class # => Float
#     ruby = JSON.parse('2.0e2')
#     ruby # => 200
#     ruby.class # => Float
#
# Boolean:
#     ruby = JSON.parse('true')
#     ruby # => true
#     ruby.class # => TrueClass
#     ruby = JSON.parse('false')
#     ruby # => false
#     ruby.class # => FalseClass
#
# Null:
#     ruby = JSON.parse('null')
#     ruby # => nil
#     ruby.class # => NilClass
#
# #### Parsing Options
#
# ###### Input Options
#
# Option `max_nesting` (Integer) specifies the maximum nesting depth allowed;
# defaults to `100`; specify `false` to disable depth checking.
#
# With the default, `false`:
#     source = '[0, [1, [2, [3]]]]'
#     ruby = JSON.parse(source)
#     ruby # => [0, [1, [2, [3]]]]
#
# Too deep:
#     # Raises JSON::NestingError (nesting of 2 is too deep):
#     JSON.parse(source, {max_nesting: 1})
#
# Bad value:
#     # Raises TypeError (wrong argument type Symbol (expected Fixnum)):
#     JSON.parse(source, {max_nesting: :foo})
#
# ---
#
# Option `allow_nan` (boolean) specifies whether to allow NaN, Infinity, and
# MinusInfinity in `source`; defaults to `false`.
#
# With the default, `false`:
#     # Raises JSON::ParserError (225: unexpected token at '[NaN]'):
#     JSON.parse('[NaN]')
#     # Raises JSON::ParserError (232: unexpected token at '[Infinity]'):
#     JSON.parse('[Infinity]')
#     # Raises JSON::ParserError (248: unexpected token at '[-Infinity]'):
#     JSON.parse('[-Infinity]')
#
# Allow:
#     source = '[NaN, Infinity, -Infinity]'
#     ruby = JSON.parse(source, {allow_nan: true})
#     ruby # => [NaN, Infinity, -Infinity]
#
# ###### Output Options
#
# Option `symbolize_names` (boolean) specifies whether returned Hash keys should
# be Symbols; defaults to `false` (use Strings).
#
# With the default, `false`:
#     source = '{"a": "foo", "b": 1.0, "c": true, "d": false, "e": null}'
#     ruby = JSON.parse(source)
#     ruby # => {"a"=>"foo", "b"=>1.0, "c"=>true, "d"=>false, "e"=>nil}
#
# Use Symbols:
#     ruby = JSON.parse(source, {symbolize_names: true})
#     ruby # => {:a=>"foo", :b=>1.0, :c=>true, :d=>false, :e=>nil}
#
# ---
#
# Option `object_class` (Class) specifies the Ruby class to be used for each
# JSON object; defaults to Hash.
#
# With the default, Hash:
#     source = '{"a": "foo", "b": 1.0, "c": true, "d": false, "e": null}'
#     ruby = JSON.parse(source)
#     ruby.class # => Hash
#
# Use class OpenStruct:
#     ruby = JSON.parse(source, {object_class: OpenStruct})
#     ruby # => #<OpenStruct a="foo", b=1.0, c=true, d=false, e=nil>
#
# ---
#
# Option `array_class` (Class) specifies the Ruby class to be used for each JSON
# array; defaults to Array.
#
# With the default, Array:
#     source = '["foo", 1.0, true, false, null]'
#     ruby = JSON.parse(source)
#     ruby.class # => Array
#
# Use class Set:
#     ruby = JSON.parse(source, {array_class: Set})
#     ruby # => #<Set: {"foo", 1.0, true, false, nil}>
#
# ---
#
# Option `create_additions` (boolean) specifies whether to use JSON additions in
# parsing. See [\JSON Additions](#module-JSON-label-JSON+Additions).
#
# ### Generating JSON
#
# To generate a Ruby String containing JSON data, use method
# `JSON.generate(source, opts)`, where
# *   `source` is a Ruby object.
# *   `opts` is a Hash object containing options that control both input allowed
#     and output formatting.
#
#
# #### Generating JSON from Arrays
#
# When the source is a Ruby Array, JSON.generate returns a String containing a
# JSON array:
#     ruby = [0, 's', :foo]
#     json = JSON.generate(ruby)
#     json # => '[0,"s","foo"]'
#
# The Ruby Array array may contain nested arrays, hashes, and scalars to any
# depth:
#     ruby = [0, [1, 2], {foo: 3, bar: 4}]
#     json = JSON.generate(ruby)
#     json # => '[0,[1,2],{"foo":3,"bar":4}]'
#
# #### Generating JSON from Hashes
#
# When the source is a Ruby Hash, JSON.generate returns a String containing a
# JSON object:
#     ruby = {foo: 0, bar: 's', baz: :bat}
#     json = JSON.generate(ruby)
#     json # => '{"foo":0,"bar":"s","baz":"bat"}'
#
# The Ruby Hash array may contain nested arrays, hashes, and scalars to any
# depth:
#     ruby = {foo: [0, 1], bar: {baz: 2, bat: 3}, bam: :bad}
#     json = JSON.generate(ruby)
#     json # => '{"foo":[0,1],"bar":{"baz":2,"bat":3},"bam":"bad"}'
#
# #### Generating JSON from Other Objects
#
# When the source is neither an Array nor a Hash, the generated JSON data
# depends on the class of the source.
#
# When the source is a Ruby Integer or Float, JSON.generate returns a String
# containing a JSON number:
#     JSON.generate(42) # => '42'
#     JSON.generate(0.42) # => '0.42'
#
# When the source is a Ruby String, JSON.generate returns a String containing a
# JSON string (with double-quotes):
#     JSON.generate('A string') # => '"A string"'
#
# When the source is `true`, `false` or `nil`, JSON.generate returns a String
# containing the corresponding JSON token:
#     JSON.generate(true) # => 'true'
#     JSON.generate(false) # => 'false'
#     JSON.generate(nil) # => 'null'
#
# When the source is none of the above, JSON.generate returns a String
# containing a JSON string representation of the source:
#     JSON.generate(:foo) # => '"foo"'
#     JSON.generate(Complex(0, 0)) # => '"0+0i"'
#     JSON.generate(Dir.new('.')) # => '"#<Dir>"'
#
# #### Generating Options
#
# ###### Input Options
#
# Option `allow_nan` (boolean) specifies whether `NaN`, `Infinity`, and
# `-Infinity` may be generated; defaults to `false`.
#
# With the default, `false`:
#     # Raises JSON::GeneratorError (920: NaN not allowed in JSON):
#     JSON.generate(JSON::NaN)
#     # Raises JSON::GeneratorError (917: Infinity not allowed in JSON):
#     JSON.generate(JSON::Infinity)
#     # Raises JSON::GeneratorError (917: -Infinity not allowed in JSON):
#     JSON.generate(JSON::MinusInfinity)
#
# Allow:
#     ruby = [Float::NaN, Float::Infinity, Float::MinusInfinity]
#     JSON.generate(ruby, allow_nan: true) # => '[NaN,Infinity,-Infinity]'
#
# ---
#
# Option `max_nesting` (Integer) specifies the maximum nesting depth in `obj`;
# defaults to `100`.
#
# With the default, `100`:
#     obj = [[[[[[0]]]]]]
#     JSON.generate(obj) # => '[[[[[[0]]]]]]'
#
# Too deep:
#     # Raises JSON::NestingError (nesting of 2 is too deep):
#     JSON.generate(obj, max_nesting: 2)
#
# ###### Output Options
#
# The default formatting options generate the most compact JSON data, all on one
# line and with no whitespace.
#
# You can use these formatting options to generate JSON data in a more open
# format, using whitespace. See also JSON.pretty_generate.
#
# *   Option `array_nl` (String) specifies a string (usually a newline) to be
#     inserted after each JSON array; defaults to the empty String, `''`.
# *   Option `object_nl` (String) specifies a string (usually a newline) to be
#     inserted after each JSON object; defaults to the empty String, `''`.
# *   Option `indent` (String) specifies the string (usually spaces) to be used
#     for indentation; defaults to the empty String, `''`; defaults to the empty
#     String, `''`; has no effect unless options `array_nl` or `object_nl`
#     specify newlines.
# *   Option `space` (String) specifies a string (usually a space) to be
#     inserted after the colon in each JSON object's pair; defaults to the empty
#     String, `''`.
# *   Option `space_before` (String) specifies a string (usually a space) to be
#     inserted before the colon in each JSON object's pair; defaults to the
#     empty String, `''`.
#
#
# In this example, `obj` is used first to generate the shortest JSON data (no
# whitespace), then again with all formatting options specified:
#
#     obj = {foo: [:bar, :baz], bat: {bam: 0, bad: 1}}
#     json = JSON.generate(obj)
#     puts 'Compact:', json
#     opts = {
#       array_nl: "\n",
#       object_nl: "\n",
#       indent: '  ',
#       space_before: ' ',
#       space: ' '
#     }
#     puts 'Open:', JSON.generate(obj, opts)
#
# Output:
#     Compact:
#     {"foo":["bar","baz"],"bat":{"bam":0,"bad":1}}
#     Open:
#     {
#       "foo" : [
#         "bar",
#         "baz"
#     ],
#       "bat" : {
#         "bam" : 0,
#         "bad" : 1
#       }
#     }
#
# ## JSON Additions
#
# When you "round trip" a non-String object from Ruby to JSON and back, you have
# a new String, instead of the object you began with:
#     ruby0 = Range.new(0, 2)
#     json = JSON.generate(ruby0)
#     json # => '0..2"'
#     ruby1 = JSON.parse(json)
#     ruby1 # => '0..2'
#     ruby1.class # => String
#
# You can use JSON *additions* to preserve the original object. The addition is
# an extension of a ruby class, so that:
# *   JSON.generate stores more information in the JSON string.
# *   JSON.parse, called with option `create_additions`, uses that information
#     to create a proper Ruby object.
#
#
# This example shows a Range being generated into JSON and parsed back into
# Ruby, both without and with the addition for Range:
#     ruby = Range.new(0, 2)
#     # This passage does not use the addition for Range.
#     json0 = JSON.generate(ruby)
#     ruby0 = JSON.parse(json0)
#     # This passage uses the addition for Range.
#     require 'json/add/range'
#     json1 = JSON.generate(ruby)
#     ruby1 = JSON.parse(json1, create_additions: true)
#     # Make a nice display.
#     display = <<EOT
#     Generated JSON:
#       Without addition:  #{json0} (#{json0.class})
#       With addition:     #{json1} (#{json1.class})
#     Parsed JSON:
#       Without addition:  #{ruby0.inspect} (#{ruby0.class})
#       With addition:     #{ruby1.inspect} (#{ruby1.class})
#     EOT
#     puts display
#
# This output shows the different results:
#     Generated JSON:
#       Without addition:  "0..2" (String)
#       With addition:     {"json_class":"Range","a":[0,2,false]} (String)
#     Parsed JSON:
#       Without addition:  "0..2" (String)
#       With addition:     0..2 (Range)
#
# The JSON module includes additions for certain classes. You can also craft
# custom additions. See [Custom \JSON
# Additions](#module-JSON-label-Custom+JSON+Additions).
#
# ### Built-in Additions
#
# The JSON module includes additions for certain classes. To use an addition,
# `require` its source:
# *   BigDecimal: `require 'json/add/bigdecimal'`
# *   Complex: `require 'json/add/complex'`
# *   Date: `require 'json/add/date'`
# *   DateTime: `require 'json/add/date_time'`
# *   Exception: `require 'json/add/exception'`
# *   OpenStruct: `require 'json/add/ostruct'`
# *   Range: `require 'json/add/range'`
# *   Rational: `require 'json/add/rational'`
# *   Regexp: `require 'json/add/regexp'`
# *   Set: `require 'json/add/set'`
# *   Struct: `require 'json/add/struct'`
# *   Symbol: `require 'json/add/symbol'`
# *   Time: `require 'json/add/time'`
#
#
# To reduce punctuation clutter, the examples below show the generated JSON via
# `puts`, rather than the usual `inspect`,
#
# BigDecimal:
#     require 'json/add/bigdecimal'

# ### Custom JSON Additions
#
# In addition to the JSON additions provided, you can craft JSON additions of
# your own, either for Ruby built-in classes or for user-defined classes.
#
# Here's a user-defined class `Foo`:
#     class Foo
#       attr_accessor :bar, :baz
#       def initialize(bar, baz)
#         self.bar = bar
#         self.baz = baz
#       end
#     end
#
# Here's the JSON addition for it:
#     # Extend class Foo with JSON addition.
#     class Foo
#       # Serialize Foo object with its class name and arguments
#       def to_json(*args)
#         {
#           JSON.create_id  => self.class.name,
#           'a'             => [ bar, baz ]
#         }.to_json(*args)
#       end
#       # Deserialize JSON string by constructing new Foo object with arguments.
#       def self.json_create(object)
#         new(*object['a'])
#       end
#     end
#
# Demonstration:
#     require 'json'
#     # This Foo object has no custom addition.
#     foo0 = Foo.new(0, 1)
#     json0 = JSON.generate(foo0)
#     obj0 = JSON.parse(json0)
#     # Lood the custom addition.
#     require_relative 'foo_addition'
#     # This foo has the custom addition.
#     foo1 = Foo.new(0, 1)
#     json1 = JSON.generate(foo1)
#     obj1 = JSON.parse(json1, create_additions: true)
#     #   Make a nice display.
#     display = <<EOT
#     Generated JSON:
#       Without custom addition:  #{json0} (#{json0.class})
#       With custom addition:     #{json1} (#{json1.class})
#     Parsed JSON:
#       Without custom addition:  #{obj0.inspect} (#{obj0.class})
#       With custom addition:     #{obj1.inspect} (#{obj1.class})
#     EOT
#     puts display
#
# Output:
#
#     Generated JSON:
#       Without custom addition:  "#<Foo:0x0000000006534e80>" (String)
#       With custom addition:     {"json_class":"Foo","a":[0,1]} (String)
#     Parsed JSON:

#

  #         becomes the source.
  #     *   If `source` responds to instance method `to_io`, `source.to_io.read`
  #         becomes the source.
  #     *   If `source` responds to instance method `read`, `source.read` becomes
  #         the source.
  #     *   If both of the following are true, source becomes the String `'null'`:
  #         *   Option `allow_blank` specifies a truthy value.
  #         *   The source, as defined above, is `nil` or the empty String `''`.
  #
  #     *   Otherwise, `source` remains the source.
  #
  # *   Argument `proc`, if given, must be a Proc that accepts one argument. It
  #     will be called recursively with each result (depth-first order). See
  #     details below. BEWARE: This method is meant to serialise data from trusted
  #     user input, like from your own database server or clients under your
  #     control, it could be dangerous to allow untrusted users to pass JSON
  #     sources into it.
  # *   Argument `opts`, if given, contains a Hash of options for the parsing. See
  #     [Parsing Options](#module-JSON-label-Parsing+Options). The default options
  #     can be changed via method JSON.load_default_options=.
