    8fold-marked

    0.3.9 • Public • Published

    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.

    NPM version

    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.

    tables

    Type: boolean Default: true

    Enable GFM tables. This option requires the gfm option to be true.

    breaks

    Type: boolean Default: false

    Enable GFM line breaks. This option requires the gfm option to be true.

    pedantic

    Type: boolean Default: false

    Conform to obscure parts of markdown.pl as much as possible. Don't fix any of the original markdown bugs or poor behavior.

    sanitize

    Type: boolean Default: false

    Sanitize the output. Ignore any HTML that has been input.

    smartLists

    Type: boolean Default: true

    Use smarter list behavior than the original markdown. May eventually be default with the old behavior moved into pedantic.

    smartypants

    Type: boolean Default: false

    Use "smart" typograhic punctuation for things like quotes and dashes.

    xhtml

    Type: boolean Default: false

    Self-close the tags for void elements (<br/>, <img/>, etc.) with a "/" as required by XHTML.

    baseUrl

    Type: string Default: null

    Replace relative link and image URLs with values resolved against the specified base.

    Access to lexer and parser

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

    var tokens = marked.lexer(text, options);
    console.log(marked.parser(tokens));
    var lexer = new marked.Lexer(options);
    var tokens = lexer.lex(text);
    console.log(tokens);
    console.log(lexer.rules);

    CLI

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

    Philosophy behind marked

    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.

    Benchmarks

    node v0.8.x

    $ node test --bench
    marked completed in 3411ms.
    marked (gfm) completed in 3727ms.
    marked (pedantic) completed in 3201ms.
    robotskirt completed in 808ms.
    showdown (reuse converter) completed in 11954ms.
    showdown (new converter) completed in 17774ms.
    markdown-js completed in 17191ms.

    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.

    Pro level

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

    var tokens = marked.lexer(text, options);
    console.log(marked.parser(tokens));
    var lexer = new marked.Lexer(options);
    var tokens = lexer.lex(text);
    console.log(tokens);
    console.log(lexer.rules);
    $ node
    > require('marked').lexer('> i am using marked.')
    [ { type: 'blockquote_start' },
      { type: 'paragraph',
        text: 'i am using marked.' },
      { type: 'blockquote_end' },
      links: {} ]

    Running Tests & Contributing

    If you want to submit a pull request, make sure your changes pass the test suite. If you're adding a new feature, be sure to add your own test.

    The marked test suite is set up slightly strangely: test/new is for all tests that are not part of the original markdown.pl test suite (this is where your test should go if you make one). test/original is only for the original markdown.pl tests. test/tests houses both types of tests after they have been combined and moved/generated by running node test --fix or marked --test --fix.

    In other words, if you have a test to add, add it to test/new/ and then regenerate the tests with node test --fix. Commit the result. If your test uses a certain feature, for example, maybe it assumes GFM is not enabled, you can add .nogfm to the filename. So, my-test.text becomes my-test.nogfm.text. You can do this with any marked option. Say you want line breaks and smartypants enabled, your filename should be: my-test.breaks.smartypants.text.

    To run the tests:

    cd marked/
    node test
