/*
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.
e.g.
style_html(html_source, {
'indent_size': 2,
'indent_char': ' ',
'max_char': 78,
'brace_style': 'expand'
});
