remarkable ========== [![Build Status](https://travis-ci.org/jonschlinkert/remarkable.svg?branch=master)](https://travis-ci.org/jonschlinkert/remarkable) [![NPM version](https://img.shields.io/npm/v/remarkable.svg)](https://www.npmjs.org/package/remarkable) Markdown parser done right. Fast and easy to extend. __[Live demo](http://jonschlinkert.github.io/remarkable/demo/)__ - Configurable syntax! You can add new rules and even replace existing ones. - Implements [CommonMark](http://commonmark.org/) spec + extentions (strikethrough, tables, URL autolinking, typographer). - Very high speed. ## Install node.js: ```bash npm install remarkable --save ``` bower: ```bash bower install remarkable --save ``` CDNs for browser: [jsDeliver](http://www.jsdelivr.com/#!remarkable "jsDelivr CDN") ## Usage ```js 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 (
) breaks: false, // Convert '\n' in paragraphs into
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!')); // =>

Remarkable rulezz!

``` You can define options via `set` method: ```js 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](http://commonmark.org/) mode: ```js var Remarkable = require('remarkable'); var md = new Remarkable('commonmark'); ``` ### Highligh fenced blocks To highlight content of fenced block, assing function to `highlight` option: ```js 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: ```js 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 // -- → –, --- → — }) ``` 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](https://help.github.com/articles/github-flavored-markdown/#strikethrough) - [Tables](https://help.github.com/articles/github-flavored-markdown/#tables) (GFM) ## References / Thanks Big thanks to [John MacFarlane](https://github.com/jgm) for his work on CommonMark spec and reference implementations. His work saved us a lot of time during this project development. Links: 1. https://github.com/jgm/stmd - reference CommonMark implementations in C & JS, also contains latest spec & online demo. 2. http://talk.commonmark.org - CommonMark forum, good place to collaborate developpers efforts. ## 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: ```js 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: ```js var md = new Remarkable(); md.use(plugin1) .use(plugin2, opts) .use(plugin3); ``` ## Authors - Jon Schlinkert [github/jonschlinkert](https://github.com/jonschlinkert) - Alex Kocharin [github/rlidwka](https://github.com/rlidwka) - Vitaly Puzrin [github/puzrin](https://github.com/puzrin) ## License [MIT](https://github.com/jonschlinkert/remarkable/blob/master/LICENSE)
