|
13 |
* |
|
14 |
* vkbeautify.xml(text [,indent_pattern]); |
|
15 |
* vkbeautify.json(text [,indent_pattern]); |

* vkbeautify.sql(text [,indent_pattern]); |
|

|
19 |
* @text - String; text to beatufy; |
|
20 |
* @indent_pattern - Integer | String; |
|
21 |
* Integer: number of white spaces; |
|
22 |
* String: character string to visualize indentation ( can also be a set of white spaces ) |
|
23 |
* Minify |
|

|
29 |
* |
|
30 |
* @text - String; text to minify; |
|
31 |
* @preserve_comments - Bool; [optional]; |
|
32 |
* Set this flag to true to prevent removing comments from @text ( minxml and mincss functions only. ) |
|
33 |
* |
|
34 |
* Examples: |
|
35 |
* vkbeautify.xml(text); // pretty print XML |
|
36 |
* vkbeautify.json(text, 4 ); // pretty print JSON |
|
37 |
* vkbeautify.css(text, '. . . .'); // pretty print CSS |
|
38 |
* vkbeautify.sql(text, '----'); // pretty print SQL |
|
39 |
* |
|
40 |
* vkbeautify.xmlmin(text, true);// minify XML, preserve comments |
|
41 |
* vkbeautify.jsonmin(text);// minify JSON |
|
42 |
* vkbeautify.cssmin(text);// minify CSS, remove comments ( default ) |
|
43 |
* vkbeautify.sqlmin(text);// minify SQL |
