mkd-extensions man page

Markdown embedded images have been extended to allow specifying the dimensions of the image by adding a new argument =/height/x/width/ to the link description.

The new image syntax is 

Five pseudo-protocols have been added to links

id:

The alt text is marked up and written to the output, wrapped with <a id=id> and </a>.

class:

The alt text is marked up and written to the output, wrapped with <span class=class> and </span>.

raw:

The title is written -- with no further processing -- to the output. The alt text is discarded.

abbr:

The alt text is marked up and written to the output, wrapped with <abbr title=abbr> and </abbr>.

lang:

The alt text s marked up and written to the output, wrapped with <span lang=lang> and </span>.

The markdown source document can have a 3-line Pandoc header in the format of
% title
% author(s)
% date which will be made available to the mkd_doc_title(), mkd_doc_author(), and mkd_doc_date() functions.

A definition list item is defined as =tag=
description (that is a =, followed by text, another =, a newline, 4 spaces of intent, and then more text.)

Alternatively, definition list items are defined as tag : description (This is the format that PHP Markdown Extra uses.)

Stylesheets may be defined and modified in a <style> block. A style block is parsed like any other block level html; <style> starting on column 1, raw html (or, in this case, css) following it, and either ending with a </style> at the end of the line or a </style> at the beginning of a subsequent line.

Be warned that style blocks work like footnote links -- no matter where you define them they are valid for the entire document.

Alphabetic lists (like regular numeric lists, but with alphabetic items) are supported. So:
a. this
b. is
c. an alphabetic
d. list will produce:
<ol type=a>
<li>this</li>
<li>is</li>
<li>an alphabetic</li>
<li>list</li>
</ol>

PHP Markdown Extra tables are supported; input of the form
header|header
------|------
text | text will produce:
<table>
<thead>
<tr>
<th>header</th>
<th>header</th>
</tr>
</thead>
<tbody>
<tr>
<td>text</td>
<td>text</td>
</tr>
</tbody>
</table> The dashed line can also contain : characters for formatting; if a : is at the start of a column, it tells discount to align the cell contents to the left; if it's at the end, it aligns right, and if there's one at the start and at the end, it centers.

A strikethrough syntax is supported in much the same way that ` is used to define a section of code. If you enclose text with two or more tildes, such as ~~erased text~~ it will be written as <del>erased text</del>. Like code sections, you may use as many ~ as you want, but there must be as many starting tildes as closing tildes.

PHP Markdown Extra footnotes are supported. If a footnote link begins with a ^, the first use of that footnote will generate a link down to the bottom of the rendered document, which will contain a numbered footnote with a link back to where the footnote was called.
