1018	+ * Converts to and from JSON format.
1019	+ *
1020	+ * JSON (JavaScript Object Notation) is a lightweight data-interchange
1021	+ * format. It is easy for humans to read and write. It is easy for machines
1022	+ * to parse and generate. It is based on a subset of the JavaScript
1023	+ * Programming Language, Standard ECMA-262 3rd Edition - December 1999.
1024	+ * This feature can also be found in Python. JSON is a text format that is
1025	+ * completely language independent but uses conventions that are familiar
1026	+ * to programmers of the C-family of languages, including C, C++, C#, Java,
1027	+ * JavaScript, Perl, TCL, and many others. These properties make JSON an
1028	+ * ideal data-interchange language.
1029	+ *
1030	+ * This package provides a simple encoder and decoder for JSON notation. It
1031	+ * is intended for use with client-side Javascript applications that make
1032	+ * use of HTTPRequest to perform server communication functions - data can
1033	+ * be encoded into JSON notation for use in a client-side javascript, or
1034	+ * decoded from incoming Javascript requests. JSON format is native to
1035	+ * Javascript, and can be directly eval()'ed with no further parsing
1036	+ * overhead
1037	+ *
1038	+ * All strings should be in ASCII or UTF-8 format!

14	+ *
15	+ * Usage: $minified = JSMinPlus::minify($script [, $filename])
16	+ *
17	+ * Versionlog (see also changelog.txt):
18	+ * 23-07-2011 - remove dynamic creation of OP_* and KEYWORD_* defines and declare them on top
19	+ * reduce memory footprint by minifying by block-scope
20	+ * some small byte-saving and performance improvements
21	+ * 12-05-2009 - fixed hook:colon precedence, fixed empty body in loop and if-constructs
22	+ * 18-04-2009 - fixed crashbug in PHP 5.2.9 and several other bugfixes
23	+ * 12-04-2009 - some small bugfixes and performance improvements
24	+ * 09-04-2009 - initial open sourced version 1.0

6	+ *
7	+ * ParseMaster, version 1.0.2 (2005-08-19) Copyright 2005, Dean Edwards
8	+ * a multi-pattern parser.
9	+ * KNOWN BUG: erroneous behavior when using escapeChar with a replacement

17	+ *
18	+ * ----------------------------------------------------------------------
19	+ * changelog:
20	+ * 1.1 : correct a bug, '\0' packed then unpacked becomes '\'.
21	+ * ----------------------------------------------------------------------
22	+ *
23	+ * examples of usage :
24	+ * $myPacker = new JavaScriptPacker($script, 62, true, false);
25	+ * $packed = $myPacker->pack();
26	+ *
27	+ * or

29	+ * $myPacker = new JavaScriptPacker($script, 'Normal', true, false);
30	+ * $packed = $myPacker->pack();
31	+ *
32	+ * or (default values)
33	+ *
34	+ * $myPacker = new JavaScriptPacker($script);
35	+ * $packed = $myPacker->pack();
36	+ *
37	+ *
38	+ * params of the constructor :
39	+ * $script: the JavaScript to pack, string.
40	+ * $encoding: level of encoding, int or string :
41	+ * 0,10,62,95 or 'None', 'Numeric', 'Normal', 'High ASCII'.
42	+ * default: 62.
43	+ * $fastDecode: include the fast decoder in the packed result, boolean.
44	+ * default : true.
45	+ * $specialChars: if you are flagged your private and local variables
46	+ * in the script, boolean.
47	+ * default: false.
48	+ *
49	+ * The pack() method return the compressed JavasScript, as a string.
50	+ *
51	+ * see http://dean.edwards.name/packer/usage/ for more information.
52	+ *
53	+ * Notes :
54	+ * # need PHP 5 . Tested with PHP 5.1.2, 5.1.3, 5.1.4, 5.2.3
55	+ *
56	+ * # The packed result may be different than with the Dean Edwards
57	+ * version, but with the same length. The reason is that the PHP
58	+ * function usort to sort array don't necessarily preserve the
59	+ * original order of two equal member. The Javascript sort function
60	+ * in fact preserve this order (but that's not require by the
61	+ * ECMAScript standard). So the encoded keywords order can be
62	+ * different in the two results.
63	+ *
64	+ * # Be careful with the 'High ASCII' Level encoding if you use
65	+ * UTF-8 in your files...

92	+ * Here are the available options and defaults in the base controller:
93	+ *
94	+ * 'isPublic' : send "public" instead of "private" in Cache-Control
95	+ * headers, allowing shared caches to cache the output. (default true)
96	+ *
97	+ * 'quiet' : set to true to have serve() return an array rather than sending
98	+ * any headers/output (default false)
99	+ *
100	+ * 'encodeOutput' : set to false to disable content encoding, and not send
101	+ * the Vary header (default true)
102	+ *
103	+ * 'encodeMethod' : generally you should let this be determined by
104	+ * HTTP_Encoder (leave null), but you can force a particular encoding
105	+ * to be returned, by setting this to 'gzip' or '' (no encoding)
106	+ *
107	+ * 'encodeLevel' : level of encoding compression (0 to 9, default 9)
108	+ *
109	+ * 'contentTypeCharset' : appended to the Content-Type header sent. Set to a falsey
110	+ * value to remove. (default 'utf-8')
111	+ *
112	+ * 'maxAge' : set this to the number of seconds the client should use its cache
113	+ * before revalidating with the server. This sets Cache-Control: max-age and the
114	+ * Expires header. Unlike the old 'setExpires' setting, this setting will NOT
115	+ * prevent conditional GETs. Note this has nothing to do with server-side caching.
116	+ *
117	+ * 'rewriteCssUris' : If true, serve() will automatically set the 'currentDir'
118	+ * minifier option to enable URI rewriting in CSS files (default true)
119	+ *
120	+ * 'bubbleCssImports' : If true, all @import declarations in combined CSS
121	+ * files will be move to the top. Note this may alter effective CSS values
122	+ * due to a change in order. (default false)
123	+ *
124	+ * 'debug' : set to true to minify all sources with the 'Lines' controller, which
125	+ * eases the debugging of combined files. This also prevents 304 responses.
126	+ * @see Minify_Lines::minify()
127	+ *
128	+ * 'minifiers' : to override Minify's default choice of minifier function for
129	+ * a particular content-type, specify your callback under the key of the
130	+ * content-type:
131	+ * <code>
132	+ * // call customCssMinifier($css) for all CSS minification
133	+ * $options['minifiers'][Minify::TYPE_CSS] = 'customCssMinifier';
134	+ *
135	+ * // don't minify Javascript at all
136	+ * $options['minifiers'][Minify::TYPE_JS] = '';
137	+ * </code>
138	+ *
139	+ * 'minifierOptions' : to send options to the minifier function, specify your options
140	+ * under the key of the content-type. E.g. To send the CSS minifier an option:
141	+ * <code>
142	+ * // give CSS minifier array('optionName' => 'optionValue') as 2nd argument
143	+ * $options['minifierOptions'][Minify::TYPE_CSS]['optionName'] = 'optionValue';
144	+ * </code>
145	+ *
146	+ * 'contentType' : (optional) this is only needed if your file extension is not
147	+ * js/css/html. The given content-type will be sent regardless of source file
148	+ * extension, so this should not be used in a Groups config with other
149	+ * Javascript/CSS files.
150	+ *
151	+ * Any controller options are documented in that controller's setupSources() method.
152	+ *
153	+ * @param mixed $controller instance of subclass of Minify_Controller_Base or string
154	+ * name of controller. E.g. 'Files'
155	+ *
156	+ * @param array $options controller/serve options
