+ Style HTML
+---------------
+
+ Written by Nochum Sossonko, (nsossonko@hotmail.com)
+
+ Based on code initially developed by: Einar Lielmanis, <einar@jsbeautifier.org>
+ http://jsbeautifier.org/
+
+ Usage:
+ style_html(html_source);
+
+ style_html(html_source, options);
+
+ The options are:
+ indent_inner_html (default false) — indent <head> and <body> sections,
+ indent_size (default 4) — indentation size,
+ indent_char (default space) — character to indent with,
+ wrap_line_length (default 250) - maximum amount of characters per line (0 = disable)
+ 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"
+ preserve_newlines (default true) - whether existing line breaks before elements should be preserved
+ Only works before elements, not inside tags or for text.
+ max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk
+ indent_handlebars (default false) - format and indent {{#foo}} and {{/foo}}
+
+ e.g.
+
+ style_html(html_source, {
+ 'indent_inner_html': false,
+ 'indent_size': 2,
+ 'indent_char': ' ',
+ 'wrap_line_length': 78,
+ 'brace_style': 'expand',
+ 'unformatted': ['a', 'sub', 'sup', 'b', 'i', 'u'],
+ 'preserve_newlines': true,
+ 'max_preserve_newlines': 5,
+ 'indent_handlebars': false
+ });
