Package Exports

remarkable
remarkable/lib/common/utils
remarkable/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (remarkable) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

remarkable

Markdown parser done right. Fast and easy to extend.

Live demo

Configurable syntax! You can add new rules and even replace existing ones.
Implements CommonMark spec + extentions (strikethrough, tables, URL autolinking, typographer).
Very high speed.

Install

node.js:

npm install remarkable --save

bower:

bower install remarkable --save

Usage

var Remarkable = require('remarkable');

// This values are default
var md = new Remarkable({
  html:         false,        // Enable html tags in source
  xhtmlOut:     false,        // Use '/' to close single tags (<br />)
  breaks:       false,        // Convert '\n' in paragraphs into <br>
  langPrefix:   'language-',  // CSS language prefix for fenced blocks
  linkify:      false,        // Autoconvert url-like texts to links
  typographer:  false,        // Enable smartypants and other sweet transforms

  // Highlighter function. Should return escaped html,
  // or '' if input not changed
  highlight: function (/*str, , lang*/) { return ''; }
});

console.log(md.parse('# Remarkable rulezz!'));
// => <h1>Remarkable rulezz!</h1>

You can define options via set method:

var Remarkable = require('remarkable');
var md = new Remarkable();

md.set({
  html: false,
  breaks: true
});

Note. To acheive best performance, don't modify Remarkable instance on the fly. If you need several configurations - create multiple instances and setup each appropriately.

You can also reset parser to strict CommonMark mode:

var Remarkable = require('remarkable');
var md = new Remarkable('commonmark');

Highligh fenced blocks

To highlight content of fenced block, assing function to highlight option:

var Remarkable = require('remarkable');
var hljs       = require('highlight.js') // https://highlightjs.org/

// This values are default
var md = new Remarkable({
  highlight: function (str, lang) {
    if (lang && hljs.getLanguage(lang)) {
      try {
        return hljs.highlight(lang, str).value;
      } catch (__) {}
    }

    try {
      return hljs.highlightAuto(str).value;
    } catch (__) {}

    return ''; // use external default escaping
  }
});

Typorgapher

Though full weigh typograpic replacements are language specific, remarkable provides the most common and universal case coverage:

var Remarkable = require('remarkable');
var md = new Remarkable({ typographer: true });

// This values are default
md.typographer.set({
  singleQuotes: '‘’', // set empty to disable
  doubleQuotes: '“”', // set '«»' for russian, '„“' for deutch, empty to disable
  copyright:    true, // (c) (C) → ©
  trademark:    true, // (tm) (TM) → ™
  registered:   true, // (r) (R) → ®
  plusminus:    true, // +- → ±
  paragraph:    true, // (p) (P) -> §
  ellipsis:     true, // ... → … (also ?.... → ?.., !.... → !..)
  dupes:        true, // ???????? → ???, !!!!! → !!!, `,,` → `,`
  dashes:       true  // -- → &ndash;, --- → &mdash;
})

Of cause, you can add your own rules or replace default one with something more advanced, specific for your language.

More extras

This extentions are enabled by default:

Strikethrough
Tables (GFM)

References / Thanks

Big thanks to John MacFarlane for his work on CommonMark spec and reference implementations. His work saved us a lot of time during this project development.

Development / Modification

Parser consists of several responsibilities chains, filled with rules. You can reconfigure anyone as you wish. Render also can be modified and extended. See source code to understand details. Pay attention to this properties:

Remarkable.block
Remarkable.block.ruler
Remarkable.inline
Remarkable.inline.ruler
Remarkable.typographer
Remarkable.typographer.ruler
Remarkable.linkifier
Remarkable.linkifier.ruler
Remarkable.renderer
Remarkable.renderer.rules

To prettify plugins init, Remarked has .use() helper for curried calls:

var md = new Remarkable();

md.use(plugin1)
  .use(plugin2, opts)
  .use(plugin3);
