mmd.js is a standalone minimalist Markdown parser written in ~815 bytes of JavaScript.

All the cool kids use Markdown. If you are not familiar with it already, have a look at the original Markdown syntax. Check the source code of this page, it is written in Markdown and parsed using mmd.js.

mmd.js is only small because of its simple design and feature set. Using dirty size optimization tricks it should be possible to reach the 5-600 bytes mark. Maybe smaller. Except that's not the idea. Enough yak shaving!

The input text is split into blocks separated by one or more blank lines. The type of each block is determined by checking the first character of the block. Headers, HTML and paragraphs are handled separetely. Multi line blocks are split using a regular expression. HTML escaping and span elements ( link, images, emphasis ) are processed for each line of the blocks. This allow to be close to the original Markdown syntax.

<script>console.log( mmd('Markdown is **sweet**') );</script>
