- JS Beautifier
----------------
-
-
- Written by Einar Lielmanis, <einar@jsbeautifier.org>
- http://jsbeautifier.org/
-
- Originally converted to javascript by Vital, <vital76@gmail.com>
- "End braces on own line" added by Chris J. Shull, <chrisjshull@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,
- preserve_max_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk,
-
- jslint_happy (default false) - if true, then jslint-stricter mode is enforced.
-
- jslint_happy !jslint_happy
- ---------------------------------
- function () function()
-
- brace_style (default "collapse") - "collapse" | "expand" | "end-expand" | "expand-strict"
- put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line.
-
- expand-strict: put brace on own line even in such cases:
-
- var a =
- {
- a: 5,
- b: 6
- }
- This mode may break your scripts - e.g "return { a: 1 }" will be broken into two lines, so beware.
-
- space_before_conditional (default true) - should the space before conditional statement be added, "if(true)" vs "if (true)",
-
- unescape_strings (default false) - should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65"
-
- e.g
-
- js_beautify(js_source_text, {
- 'indent_size': 1,
- 'indent_char': '\t'
- });
