Introduction

This is not another markdown parser.

Well, okay, yes it is. But it handles a lot more than you're probably used to finding in just a single package. This generator can process Markdown files written in:

• The standard Gruber syntax
• The GitHub Flavored Markdown syntax (including language-specific codeblock fences)

It also does some "non-traditional" work, too, that I find pretty damn useful:

• Inline metadata support (something Maruku does not do). By this I mean you can add an ID to anything; for example, this format:
  Here is [a very special]{: #special .words1 .class1 lie=false} piece of text!
  Produces this text:
  <p>Here is <span id="special" class="words1 class1" lie="false">a very special</span> piece of text
  Maruku only allowed you to do inline IDs for stylized text, like code, strong, or emphasis. Now, if you wrap your text in [ ] brackets, you can continue to add Maruku metadata syntax and expect it to work.(NOT YET SUPPORTED)

• Strikethroughs, using ~~. For example, This is a ~~strikethrough~~ turns into This is a <del>strikethrough</del>

• Tables, with support for left,right, and center alignment (NOT YET SUPPORTED)

• Conversion of Note: , Tip: , and Warning: blocks into Twitter Bootstrap alert blocks. Awesome!

• Build-time highlighting of <pre> code blocks. Enabled by default, see below for configuration instructions.

• [[keys: ]] converts keyboard characters into a pretty-printed format

• [[menu: ]] converts a comma-seprated list into a pretty-printed menu

• Markdown wrapped in <div marked="1"> is processed.

• Width and height attributes can be added to images with <x, y>

namp was forked from marked, which is a super-fast Markdown parser that handles all the standard GFM syntax.

For a demonstration of all the additional add-ons, take a look at the /doc folder.

Usage and Configuration

First, install from npm:

npm install namp

Then, add the module via a require() statement, feed it a file, and let it go:

var namp = require('namp');
var fs = require('fs');

fs.readFile("SYNTAX.md", "utf8", function (err, data) {
  if (!err) {
    var output = namp(data, {highlight: true } );
    fs.writeFileSync("SYNTAX.html", output.html);

    console.log("Finished! By the way, I found this metadata:\n" + console.log(output.metadata));
  }
});

That's it! Notice that the converter takes two parameters:

• data, the contents of the Markdown file
• options, an object containing the following properties:
  • highlight enables build-time syntax highlighting for code blocks (this is true by default). This uses the highlight.js processor, so you'll still need to define your own CSS for colors

The result of the conversion is an object with two properties:

• html, the transformed HTML
• metadata, an object containing the document metadata values (undefined if there's none)

Document Metadata Handling

A special note must be made for the way document metadata blocks are handled. These are a list of arbitrary Key: Value mappings defined at the very start of a document. They are optional, but can be useful as content to be used in other locations. doc/SYNTAX.md shows how you can define these properties.

Here's the original marked README:

marked

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

Benchmarks

node v0.4.x

$ node test --bench
marked completed in 12071ms.
showdown (reuse converter) completed in 27387ms.
showdown (new converter) completed in 75617ms.
markdown-js completed in 70069ms.

node v0.6.x

$ node test --bench
marked completed in 6448ms.
marked (gfm) completed in 7357ms.
marked (pedantic) completed in 6092ms.
discount completed in 7314ms.
showdown (reuse converter) completed in 16018ms.
showdown (new converter) completed in 18234ms.
markdown-js completed in 24270ms.

Marked is now faster than Discount, which is written in C.

For those feeling skeptical: These benchmarks run the entire markdown test suite 1000 times. The test suite tests every feature. It doesn't cater to specific aspects.

Install

$ npm install marked

Another Javascript Markdown Parser

The point of marked was to create a markdown compiler where it was possible to frequently parse huge chunks of markdown without having to worry about caching the compiled output somehow...or blocking for an unnecesarily long time.

marked is very concise and still implements all markdown features. It is also now fully compatible with the client-side.

marked more or less passes the official markdown test suite in its entirety. This is important because a surprising number of markdown compilers cannot pass more than a few tests. It was very difficult to get marked as compliant as it is. It could have cut corners in several areas for the sake of performance, but did not in order to be exactly what you expect in terms of a markdown rendering. In fact, this is why marked could be considered at a disadvantage in the benchmarks above.

Along with implementing every markdown feature, marked also implements GFM features.

Options

marked has 4 different switches which change behavior.

• pedantic: Conform to obscure parts of markdown.pl as much as possible. Don't fix any of the original markdown bugs or poor behavior.
• gfm: Enable github flavored markdown (enabled by default).
• sanitize: Sanitize the output. Ignore any HTML that has been input.
• highlight: A callback to highlight code blocks.

None of the above are mutually exclusive/inclusive.

Usage

// Set default options
marked.setOptions({
  gfm: true,
  pedantic: false,
  sanitize: true,
  // callback for code highlighter
  highlight: function(code, lang) {
    if (lang === 'js') {
      return javascriptHighlighter(code);
    }
    return code;
  }
});
console.log(marked('i am using __markdown__.'));

You also have direct access to the lexer and parser if you so desire.

var tokens = marked.lexer(text);
console.log(marked.parser(tokens));

$ node
> require('marked').lexer('> i am using marked.')
[ { type: 'blockquote_start' },
  { type: 'paragraph',
    text: 'i am using marked.' },
  { type: 'blockquote_end' },
  links: {} ]

CLI

$ marked -o hello.html
hello world
^D
$ cat hello.html
<p>hello world</p>
