The lus_attr_escape() and lus_body_escape() functions escape all problematic characters in (X)HTML: ‘<’,
‘>’, ‘&’, ‘"’; and ‘<’, ‘>’, ‘&’ respectively. They accept a string str of the length len and output
into ob buffer.
All provided renderers come with two flavors, _html producing HTML code (self-closing tags are rendered
like this: <hr>), and _xhtml producing XHTML code (self-closing tags like <hr />).
mkd_html and mkd_xhtml implement standard markdown to (X)HTML translation without any extension.
discount_html and discount_xhtml implement on top of the standard markdown some of the extensions found
in Discount and PHP-Markdown-like tables. Here is a list of all extensions included in these renderers:
• image size specification, by appending "=(width)x(height)" to the link
• pseudo-protocols in links:
• abbr:description for <abbr title="description">...</abbr>
• class:name for <span class="name">...</span>
• id:name for <span id="name">...</span>
• raw:text for verbatim unprocessed text inclusion
• class blocks: blockquotes beginning with %class% will be rendered as a div of the given class(es)
nat_html and nat_xhtml implement on top of Discount extensions and Natasha's own extensions. Here is a
list of these extensions:
• id attribute for headers, using the syntax id#Header text
• class attribute for paragraphs, by putting class name(s) between parenthesis at the very beginning of
the paragraph
• <ins> and <del> spans, using respectively ++ and -- as delimiters (with emphasis-like restrictions,
i.e. an opening delimiter cannot be followed by a whitespace, and a closing delimiter cannot be
preceded by a whitespace)
• plain <span> without attribute, using emphasis-like delimiter |
