2 * vkBeautify - javascript plugin to pretty-print or minify text in XML, JSON and CSS formats.
3 *
4 * Version - 0.97.00.beta
5 * Copyright (c) 2012 Vadim Kiryukhin
6 * vkiryukhin @ gmail.com
7 * http://www.eslinstructor.net/vkbeautify/
8 *
9 * Dual licensed under the MIT and GPL licenses:

11 * http://www.gnu.org/licenses/gpl.html
12 *
13 * Pretty print
14 *
15 * vkbeautify.xml(text [,indent_pattern]);
16 * vkbeautify.json(text [,indent_pattern]);
17 * vkbeautify.css(text [,indent_pattern]);
18 * vkbeautify.sql(text [,indent_pattern]);
19 *
20 * @text - String; text to beatufy;
21 * @indent_pattern - Integer | String;
22 * Integer: number of white spaces;
23 * String: character string to visualize indentation ( can also be a set of white spaces )
24 * Minify
25 *
26 * vkbeautify.xmlmin(text [,preserve_comments]);
27 * vkbeautify.jsonmin(text);
28 * vkbeautify.cssmin(text [,preserve_comments]);
29 * vkbeautify.sqlmin(text);
30 *
31 * @text - String; text to minify;
32 * @preserve_comments - Bool; [optional];
33 * Set this flag to true to prevent removing comments from @text ( minxml and mincss functions only. )
34 *
35 * Examples:
36 * vkbeautify.xml(text); // pretty print XML
37 * vkbeautify.json(text, 4 ); // pretty print JSON
38 * vkbeautify.css(text, '. . . .'); // pretty print CSS
39 * vkbeautify.sql(text, '----'); // pretty print SQL
40 *
41 * vkbeautify.xmlmin(text, true);// minify XML, preserve comments
42 * vkbeautify.jsonmin(text);// minify JSON
43 * vkbeautify.cssmin(text);// minify CSS, remove comments ( default )
44 * vkbeautify.sqlmin(text);// minify SQL
45 *
