|
31 * @text - String; text to minify;
|

|
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 )
|
|
|
