JS Beautifier
---------------
Written by Einar Lielmanis, <[email protected]>
http://jsbeautifier.org/
Originally converted to javascript by Vital, <[email protected]>
Rewritten by Austin Cheney on 30 Jan 2011 for use with:
http://prettydiff.com/prettydiff.js
You are free to use this in any way you want, in case you find this
useful or working for you.
Options:
Options are properties of a single object literal named "args".
* args.insize (default 4) — indentation size
* args.inchar (default space) — character to indent with
* args.preserve (default true) — whether existing line breaks should
be preserved
* args.preserve_max (default unlimited) - maximum number of line
breaks to be preserved in one chunk
* args.inlevel (default 0) — initial indentation level, you probably
won't need this ever
* args.space (default false) — if true, then space is added between
"function ()" (jslint is happy about this); if false, then the common
"function()" output is used.
* args.braces (default false) - ANSI / Allman brace style, each
opening/closing brace gets its own line.
* args.inarray --- unknown
* args.comments - whether or not comments should be indented. Values
are "indent" or "noindent"
Variable summary is not provided a scope by js_beautify. It is
intended for use in closure to provide an analysis report for use
external to the js_beautify function.
