+        end_with_newline (false)          - end with a newline

+
+  Written by Nochum Sossonko, (nsossonko@hotmail.com)
+
+  Based on code initially developed by: Einar Lielmanis, 
+    http://jsbeautifier.org/
+
+  Usage:
+    style_html(html_source);
+
+    style_html(html_source, options);
+
+  The options are:
+    indent_inner_html (default false)  — indent  and  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
+    });

+
+
+  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,
+    max_preserve_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"
+            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.
+
+    space_before_conditional (default true) - should the space before conditional statement be added, "if(true)" vs "if (true)",
+
+    unescape_strings (default false) - should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65"
+
+    wrap_line_length (default unlimited) - lines should wrap at next opportunity after this number of characters.
+          NOTE: This is not a hard limit. Lines will continue until a point where a newline would
+                be preserved if it were present.
