remarkable

Markdown parser done right. Fast and easy to extend.

• Configurable syntax! You can add new rules and even replace existing ones.
• Implements CommonMark spec + extentions:
  • strikeout
  • tables
  • linkify (autoconvert links from text)
  • typographer
• Very high speed.

Live demo

Install

node.js:

npm install remarkable --save

bower:

bower install remarkable --save

Usage

var Remarkable = require('remarkable');

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');

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 });

md.typographer.set({
  singleQuotes: '‘’',
  doubleQuotes: '“”', // «» - russian, „“ - deutch
  copyright:    true, // (c) (C) → ©
  trademark:    true, // (tm) (TM) → ™
  registered:   true, // (r) (R) → ®
  plusminus:    true, // +- → ±
  paragraph:    true, // (p) (P) -> §
  ellipsis:     true, // ... → …
  dupes:        true, // ???????? → ???, !!!!! → !!!, `,,` → `,`
  emDashes:     true  // -- → —
})

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
