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 (defaults to inline tags) - 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']
});
