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" | "none" |
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, or attempt to keep them where they are. |
unformatted (defaults to inline tags) - list of tags, that shouldn't be reformatted |
content_unformatted (defaults to pre tag) - list of tags, that its content 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 |
extra_liners (default [head,body,/html]) -List of tags that should have an extra newline before them. |
|
e.g. |
|
style_html(html_source, { |
'indent_inner_html': false, |
'indent_size': 2, |
'indent_char': ' ', |
'wrap_line_length': 78, |
'brace_style': 'expand', |
'preserve_newlines': true, |
'max_preserve_newlines': 5, |
'indent_handlebars': false, |
'extra_liners': ['/html'] |
}); |
