<markdown.MARKDOWN src charset fontifier>

This example shows how to embed markdown elements into HTML.

The example uses a service that returns an HTML document whose sole element is a markdown text. Before being delivered to the client, the markdown text is parsed and automatically compiled into HTML.


var md = require( hop.markdown );

service mdtag( o ) {
   var name = o && "name" in o ? : "bar";
   return <html>
toto n'est pas content

  * toto
  * tutu ${name}
  * titi
tutu non plus.

console.log( "Go to \"http://%s:%d/hop/mtag\"", hop.hostname, hop.port );
