File: json2.asp

AXE(ASP Xtreme Evolution) JSON parser based on Douglas Crockford json2.js.

This class is the result of Classic ASP JSON topic revisited by Fabio Zendhi
Nagao (nagaozen). JSON2.ASP is a better option over JSON.ASP because it embraces
the AXE philosophy of real collaboration over the languages. It works under the
original json parser, so this class is strict in the standard rules, it also
brings more of the Javascript json feeling to other ASP languages (eg. no more
oJson.getElement("foo") stuff, just oJson.foo and you get it).

Class: JSON

JSON (Javascript Object Notation) is a lightweight data-interchange format. It
is easy for humans to read and write. It is easy for machines to parse and
generate. It is based on a subset of the Javascript Programming Language,
Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is
completely language independent but uses conventions that are familiar to
programmers of the C-family of languages, including C, C++, C#, Java,
Javascript, Perl, Python, and many others. These properties make JSON an ideal
data-interchange language.

Notes:

    - Javascript extensions concept inspired by Troy Foster JSON2.ASP work <http://tforster.wik.is/ASP_Classic_Practices_For_The_21st_Century/JSON4ASP>.
    - Javascript JSON parser is the Douglas Crockford json2.js <http://www.JSON.org/json2.js>, without the first line alert(...) and fixing "this.JSON = {};" to "JSON = {};" to make it JScript compatible.
    - Javascript JSON.toXML is based on the Prof. Stefan Gössner "Converting Between XML and JSON" pragmatic approach <http://www.xml.com/pub/a/2006/05/31/converting-between-xml-and-json.html>.

Function: parse

This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception.

Parameters:

    (string) - Valid JSON text.

Returns:

    (mixed) - a Javascript value, usually an object or array.

Example:

(start code)

dim Info : set Info = JSON.parse(join(array( _
    "{", _
    " ""firstname"": ""Fabio"",", _
    " ""lastname"": ""長尾"",", _
    " ""alive"": true,", _
    " ""age"": 27,", _
    " ""nickname"": ""nagaozen"",", _
    " ""fruits"": [", _
    " ""banana"",", _
    " ""orange"",", _
    " ""apple"",", _
    " ""papaya"",", _
    " ""pineapple""", _
    " ],", _
    " ""complex"": {", _
    " ""real"": 1,", _
    " ""imaginary"": 2", _
    " }", _
    "}" _
)))

Response.write(Info.firstname & vbNewline) ' prints Fabio
Response.write(Info.alive & vbNewline) ' prints True
Response.write(Info.age & vbNewline) ' prints 27
Response.write(Info.fruits.get(0) & vbNewline) ' prints banana
Response.write(Info.fruits.get(1) & vbNewline) ' prints orange
Response.write(Info.complex.real & vbNewline) ' prints 1
Response.write(Info.complex.imaginary & vbNewline) ' prints 2

' You can also enumerate object properties ...

dim key : for each key in Info.keys()
    Response.write( key & vbNewline )
next

' which prints:

' firstname
' lastname
' alive
' age
' nickname
' fruits
' complex

set Info = nothing

(end code)





Function: stringify

This method produces a JSON text from a Javascript value.

Parameters:

    (mixed) - any Javascript value, usually an object or array.
    (mixed) - an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings.
    (mixed) - an optional parameter that specifies the indentation of nested structures. If it is omitted, the text will be packed without extra whitespace. If it is a number, it will specify the number of spaces to indent at each level. If it is a string (such as '\t' or '&nbsp;'), it contains the characters used to indent at each level.

Returns:

    (string) - a string that contains the serialized JSON text.

Example:

(start code)

dim Info : set Info = JSON.parse("{""firstname"":""Fabio"", ""lastname"":""長尾""}")
Info.set "alive", true
Info.set "age", 27
Info.set "nickname", "nagaozen"
Info.set "fruits", array("banana","orange","apple","papaya","pineapple")
Info.set "complex", JSON.parse("{""real"":1, ""imaginary"":1}")

Response.write( JSON.stringify(Info, null, 2) & vbNewline ) ' prints the text below:
'{
' "firstname": "Fabio",
' "lastname": "長尾",
' "alive": true,
' "age": 27,
' "nickname": "nagaozen",
' "fruits": [
' "banana",
' "orange",
' "apple",
' "papaya",
' "pineapple"
' ],
' "complex": {
' "real": 1,
' "imaginary": 1
' }
'}

set Info = nothing

(end code)





Function: toXML

This method produces a XML text from a Javascript value.

Parameters:

    (mixed) - any Javascript value, usually an object or array.
    (string) - an optional parameter that determines what tag should be used as a container for the output. Defaults to none.

Returns:

    (string) - a string that contains the serialized XML text.

Example:

(start code)

dim Info : set Info = JSON.parse("{""firstname"":""Fabio"", ""lastname"":""長尾""}")
Info.set "alive", true
Info.set "age", 27
Info.set "nickname", "nagaozen"
Info.set "fruits", array("banana","orange","apple","papaya","pineapple")
Info.set "complex", JSON.parse("{""real"":1, ""imaginary"":1}")

Response.write( JSON.toXML(Info) & vbNewline ) ' prints the text below:
'<firstname>Fabio</firstname>
'<lastname>長尾</lastname>
'<alive>true</alive>
'<age>27</age>
'<nickname>nagaozen</nickname>
'<fruits>banana</fruits>
'<fruits>orange</fruits>
'<fruits>apple</fruits>
'<fruits>papaya</fruits>
'<fruits>pineapple</fruits>
'<complex>
' <real>1</real>
' <imaginary>1</imaginary>
'</complex>

set Info = nothing

(end code)





Function: minify

This method can be used as a helper to enable comments in json-like
configuration files. According to Douglas Crockford, using comments are fine if
you pipe the code before handing it to your JSON parser. See
<https://plus.google.com/118095276221607585885/posts/RK8qyGVaGSr>

Parameters:

    (string) - a json-like configuration string

Returns:

    (json) - valid minified json

    This file creates a global JSON object containing two methods: stringify
    and parse.

        JSON.stringify(value, replacer, space)
            value any JavaScript value, usually an object or array.

            replacer an optional parameter that determines how object
                        values are stringified for objects. It can be a
                        function or an array of strings.

            space an optional parameter that specifies the indentation
                        of nested structures. If it is omitted, the text will
                        be packed without extra whitespace. If it is a number,
                        it will specify the number of spaces to indent at each
                        level. If it is a string (such as '\t' or '&nbsp;'),
                        it contains the characters used to indent at each level.

            This method produces a JSON text from a JavaScript value.

            When an object value is found, if the object contains a toJSON
            method, its toJSON method will be called and the result will be
            stringified. A toJSON method does not serialize: it returns the
            value represented by the name/value pair that should be serialized,
            or undefined if nothing should be serialized. The toJSON method
            will be passed the key associated with the value, and this will be
            bound to the value

            For example, this would serialize Dates as ISO strings.

                Date.prototype.toJSON = function (key) {
                    function f(n) {
                        // Format integers to have at least two digits.
                        return n < 10 ? '0' + n : n;
                    }

                    return this.getUTCFullYear() + '-' +
                         f(this.getUTCMonth() + 1) + '-' +
                         f(this.getUTCDate()) + 'T' +
                         f(this.getUTCHours()) + ':' +
                         f(this.getUTCMinutes()) + ':' +
                         f(this.getUTCSeconds()) + 'Z';
                };

            You can provide an optional replacer method. It will be passed the
            key and value of each member, with this bound to the containing
            object. The value that is returned from your method will be
            serialized. If your method returns undefined, then the member will
            be excluded from the serialization.

            If the replacer parameter is an array of strings, then it will be
            used to select the members to be serialized. It filters the results
            such that only members with keys listed in the replacer array are
            stringified.

            Values that do not have JSON representations, such as undefined or
            functions, will not be serialized. Such values in objects will be
            dropped; in arrays they will be replaced with null. You can use
            a replacer function to replace those with JSON values.
            JSON.stringify(undefined) returns undefined.

            The optional space parameter produces a stringification of the
            value that is filled with line breaks and indentation to make it
            easier to read.

            If the space parameter is a non-empty string, then that string will
            be used for indentation. If the space parameter is a number, then
            the indentation will be that many spaces.

            Example:

            text = JSON.stringify(['e', {pluribus: 'unum'}]);
            // text is '["e",{"pluribus":"unum"}]'


            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'

            text = JSON.stringify([new Date()], function (key, value) {
                return this[key] instanceof Date ?
                    'Date(' + this[key] + ')' : value;
            });
            // text is '["Date(---current time---)"]'


        JSON.parse(text, reviver)
            This method parses a JSON text to produce an object or array.
            It can throw a SyntaxError exception.

            The optional reviver parameter is a function that can filter and
            transform the results. It receives each of the keys and values,
            and its return value is used instead of the original value.
            If it returns what it received, then the structure is not modified.
            If it returns undefined then the member is deleted.

            Example:

            // Parse the text. Values that look like ISO date strings will
            // be converted to Date objects.

            myData = JSON.parse(text, function (key, value) {
                var a;
                if(typeof value === 'string') {
                    a =
/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
