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}}
|
||
|
|
end_with_newline (false) - end with a newline
|
||
|
|
|
||
|
|
|
||
|
|
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,
