Written by Einar Lielmanis, <einar@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: should the space before conditional statement be added, "if(true)" vs "if (true)"
e.g
js_beautify(js_source_text, {
'indent_size': 1,
'indent_char': '\t'
});

Style HTML
---------------
Written by Nochum Sossonko, (nsossonko@hotmail.com)
Based on code initially developed by: Einar Lielmanis, <elfz@laacz.lv>
http://jsbeautifier.org/
You are free to use this in any way you want, in case you find this useful or working for you.
Usage:
style_html(html_source);
style_html(html_source, options);
The options are:
indent_size (default 4) ?? indentation size,
indent_char (default space) ?? character to indent with,
max_char (default 70) - maximum amount of characters per line,
brace_style (default "collapse") - "collapse" | "expand" | "end-expand"
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.
unformatted (default ['a']) - list of tags, that shouldn't be reformatted
indent_scripts (default normal) - "keep"|"separate"|"normal"
e.g.
style_html(html_source, {
'indent_size': 2,
'indent_char': ' ',
'max_char': 78,
'brace_style': 'expand',
'unformatted': ['a', 'sub', 'sup', 'b', 'i', 'u']

You are free to use this in any way you want, in case you find this useful or working for you.
Usage:

The options are:
indent_size (default 4) ?? indentation size,
indent_char (default space) ?? character to indent with,
e.g
css_beautify(css_source_text, {

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: should the space before conditional statement be added, "if(true)" vs "if (true)"
e.g
js_beautify(js_source_text, {
'indent_size': 1,
'indent_char': '\t'
});

Written by Nochum Sossonko, (nsossonko@hotmail.com)
Based on code initially developed by: Einar Lielmanis, <elfz@laacz.lv>
http://jsbeautifier.org/
You are free to use this in any way you want, in case you find this useful or working for you.
Usage:
style_html(html_source);
style_html(html_source, options);
The options are:
indent_size (default 4) ?? indentation size,
indent_char (default space) ?? character to indent with,
max_char (default 70) - maximum amount of characters per line,
brace_style (default "collapse") - "collapse" | "expand" | "end-expand"
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.
unformatted (default ['a']) - list of tags, that shouldn't be reformatted
indent_scripts (default normal) - "keep"|"separate"|"normal"
e.g.
style_html(html_source, {
'indent_size': 2,
'indent_char': ' ',
'max_char': 78,
'brace_style': 'expand',
'unformatted': ['a', 'sub', 'sup', 'b', 'i', 'u']
});

You are free to use this in any way you want, in case you find this useful or working for you.
Usage:

The options are:
indent_size (default 4) ?? indentation size,

css_beautify(css_source_text, {
