Enables all available rules, * but still without html, typographer & autolinker. * - ["zero"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/zero.js) - * all rules disabled. Useful to quickly setup your config via `.enable()`. * For example, when you need only `bold` and `italic` markup and nothing else. * * ##### options: * * - __html__ - `false`. Set `true` to enable HTML tags in source. Be careful! * That's not safe! You may need external sanitizer to protect output from XSS. * It's better to extend features via plugins, instead of enabling HTML. * - __xhtmlOut__ - `false`. Set `true` to add '/' when closing single tags * (`<br />`). This is needed only for full CommonMark compatibility. In real * world you will need HTML output. * - __breaks__ - `false`. Set `true` to convert `\n` in paragraphs into `<br>`. * - __langPrefix__ - `language-`. CSS language class prefix for fenced blocks. * Can be useful for external highlighters. * - __linkify__ - `false`. Set `true` to autoconvert URL-like text to links. * - __typographer__ - `false`. Set `true` to enable [some language-neutral * replacement](https://github.com/markdown-it/markdown-it/blob/master/lib/rules_core/replacements.js) + * quotes beautification (smartquotes). * - __quotes__ - `“”‘’`, String or Array. Double + single quotes replacement * pairs, when typographer enabled and smartquotes on. For example, you can * use `'«»„“'` for Russian, `'„“‚‘'` for German, and * `['«\xA0', '\xA0»', '‹\xA0', '\xA0›']` for French (including nbsp). * - __highlight__ - `null`.

If result starts with <pre... internal wrapper is skipped. * * ##### Example * * ```javascript * // commonmark mode * var md = require('markdown-it')('commonmark'); * * // default mode * var md = require('markdown-it')(); * * // enable everything * var md = require('markdown-it')({ * html: true, * linkify: true, * typographer: true * }); * ``` * * ##### Syntax highlighting * * ```js * var hljs = require('highlight.js') // https://highlightjs.org/ * * var md = require('markdown-it')({ * highlight: function (str, lang) { * if (lang && hljs.getLanguage(lang)) { * try { * return hljs.highlight(str, { language: lang, ignoreIllegals: true }).value; * } catch (__) {} * } * * return ''; // use external default escaping * } * }); * ``` * * Or with full wrapper override (if you need assign class to `<pre>`): * * ```javascript * var hljs = require('highlight.js') // https://highlightjs.org/ * * // Actual default values * var md = require('markdown-it')({ * highlight: function (str, lang) { * if (lang && hljs.getLanguage(lang)) { * try { * return '<pre class="hljs"><code>' + * hljs.highlight(str, { language: lang, ignoreIllegals: true }).value + * '</code></pre>'; * } catch (__) {} * } * * return '<pre class="hljs"><code>' + md.utils.escapeHtml(str) + '</code></pre>'; * } * }); * ``` * **/ function MarkdownIt(presetName, options) { if (!(this instanceof MarkdownIt)) { return new MarkdownIt(presetName, options); } if (!options) { if (!utils.isString(presetName)) { options = presetName || {}; presetName = "default"; } } /** * MarkdownIt#inline -> ParserInline * * Instance of [[ParserInline]].
