The Abbreviations extension adds the ability to define abbreviations. Specifically, any defined abbreviation is wrapped in an <abbr> tag.

The Abbreviations extension is included in the standard Markdown library.


Abbreviations are defined using the syntax established in PHP Markdown Extra.

Thus, the following text (taken from the above referenced PHP documentation):

The HTML specification
is maintained by the W3C.

*[HTML]: Hyper Text Markup Language
*[W3C]:  World Wide Web Consortium

will be rendered as:

<p>The <abbr title="Hyper Text Markup Language">HTML</abbr> specification
is maintained by the <abbr title="World Wide Web Consortium">W3C</abbr>.</p>


See Extensions for general extension usage, specify markdown.extensions.abbr as the name of the extension.

This extension does not accept any special configuration options.
