Source

This fork is starting out of necessity. To be clear, 8fold is not attempting to hijack the main project.

If the main project appears to pick up again, then we will probably let it go back to those capable hands. In the meantime, this project is here for Marked users to come and collaborate (I hope the folks on the main project are okay). All PRs should be submitted to this repo so we can perform merges into master here and submit those to the main project as well.

marked

A full-featured markdown parser and compiler, written in JavaScript. Built for speed.

Install

npm install marked --save

Usage

Minimal usage:

var marked = require('marked');
console.log(marked('I am using __markdown__.'));
// Outputs: <p>I am using <strong>markdown</strong>.</p>

Example setting options with default values:

var marked = require('marked');
marked.setOptions({
  renderer: new marked.Renderer(),
  gfm: true,
  tables: true,
  breaks: false,
  pedantic: false,
  sanitize: false,
  smartLists: true,
  smartypants: false,
  xhtml: false,
  baseUrl: null
});

console.log(marked('I am using __markdown__.'));

Browser

<!doctype html>
<html>
<head>
  <meta charset="utf-8"/>
  <title>Marked in the browser</title>
  <script src="lib/marked.js"></script>
</head>
<body>
  <div id="content"></div>
  <script>
    document.getElementById('content').innerHTML =
      marked('# Marked in browser\n\nRendered by **marked**.');
  </script>
</body>
</html>

marked(markdownString [,options] [,callback])

markdownString

Type: string

String of markdown source to be compiled.

options

Type: object

Hash of options. Can also be set using the marked.setOptions method as seen above.

callback

Type: function

Function called when the markdownString has been fully parsed when using async highlighting. If the options argument is omitted, this can be used as the second argument.

Options

highlight

Type: function

A function to highlight code blocks. The first example below uses async highlighting with node-pygmentize-bundled, and the second is a synchronous example using highlight.js:

var marked = require('marked');

var markdownString = '```js\n console.log("hello"); \n```';

// Async highlighting with pygmentize-bundled
marked.setOptions({
  highlight: function (code, lang, callback) {
    require('pygmentize-bundled')({ lang: lang, format: 'html' }, code, function (err, result) {
      callback(err, result.toString());
    });
  }
});

// Using async version of marked
marked(markdownString, function (err, content) {
  if (err) throw err;
  console.log(content);
});

// Synchronous highlighting with highlight.js
marked.setOptions({
  highlight: function (code) {
    return require('highlight.js').highlightAuto(code).value;
  }
});

console.log(marked(markdownString));

highlight arguments

code

Type: string

The section of code to pass to the highlighter.

lang

Type: string

The programming language specified in the code block.

callback

Type: function

The callback function to call when using an async highlighter.

renderer

Type: object Default: new Renderer()

An object containing functions to render tokens to HTML.

Overriding renderer methods

The renderer option allows you to render tokens in a custom manner. Here is an example of overriding the default heading token rendering by adding an embedded anchor tag like on GitHub:

var marked = require('marked');
var renderer = new marked.Renderer();

renderer.heading = function (text, level) {
  var escapedText = text.toLowerCase().replace(/[^\w]+/g, '-');

  return '<h' + level + '><a name="' +
                escapedText +
                 '" class="anchor" href="#' +
                 escapedText +
                 '"><span class="header-link"></span></a>' +
                  text + '</h' + level + '>';
},

console.log(marked('# heading+', { renderer: renderer }));

This code will output the following HTML:

<h1>
  <a name="heading-" class="anchor" href="#heading-">
    <span class="header-link"></span>
  </a>
  heading+
</h1>

Block level renderer methods

code(string code, string language)
blockquote(string quote)
html(string html)
heading(string text, number level)
hr()
list(string body, boolean ordered)
listitem(string text)
paragraph(string text)
table(string header, string body)
tablerow(string content)
tablecell(string content, object flags)

flags has the following properties:

{
    header: true || false,
    align: 'center' || 'left' || 'right'
}

Inline level renderer methods

strong(string text)
em(string text)
codespan(string code)
br()
del(string text)
link(string href, string title, string text)
image(string href, string title, string text)

gfm

Type: boolean Default: true

Enable GitHub flavored markdown.
