| JS Beautifier | |

| Originally converted to javascript by Vital, <vital76@gmail.com> | |
| You are free to use this in any way you want, in case you find this useful or working for you. | |
| Usage: | |
| js_beautify(js_source_text); | |
| js_beautify(js_source_text, options); | |
| The options are: | |
| indent_size (default 4) — indentation size, | |
| indent_char (default space) — character to indent with, | |
| preserve_newlines (default true) — whether existing line breaks should be preserved, | |
| indent_level (default 0) — initial indentation level, you probably won't need this ever, | |
| space_after_anon_function (default false) — if true, then space is added between "function ()" | |
| (jslint is happy about this); if false, then the common "function()" output is used. | |
| braces_on_own_line (default false) - ANSI / Allman brace style, each opening/closing brace gets its own line. | |
| e.g | |
| js_beautify(js_source_text, {indent_size: 1, indent_char: '\t'}); | |
