MKD-EXTENSIONS(7)

NAME
mkd-extensions - Extensions to the Markdown text formatting syntax

DESCRIPTION
This version of markdown has been extended in a few ways by extending existing markup, creating new markup from scratch, and borrowing markup from other markup languages.

  Image dimensions
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
	![alt text](image =/height/x/width/ "title")

  pseudo-protocols
Three 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.

  Pandoc headers
If markdown was configured with --enable-pandoc-header, 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.

  Definition lists
If markdown was configured with --enable-dl-tag, markup for definition lists is enabled. 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.)

  embedded stylesheets
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.

  relaxed emphasis
If markdown was configured with --relaxed-emphasis, the rules for emphasis are changed so that a single _ will not count as a emphasis character if it's in the middle of a word. This is primarily for documenting code, if you don't wish to have to backquote all code references.

  alpha lists
If markdown was configured with --enable-alpha-list, 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>
