  // Changes from joyent/node:
  
  // 1. No leading slash in paths,
  //    e.g. in `url.parse('http://foo?bar')` pathname is ``, not `/`
  
  // 2. Backslashes are not replaced with slashes,
  //    so `http:\\example.org\` is treated like a relative path
  
  // 3. Trailing colon is treated like a part of the path,
  //    i.e. in `http://example.org:foo` pathname is `:foo`
  
  // 4. Nothing is URL-encoded in the resulting object,
  //    (in joyent/node some chars in auth and paths are encoded)
  
  // 5. `url.parse()` does not have `parseQueryString` argument
  
  // 6. Removed extraneous result properties: `host`, `path`, `query`, etc.,
  //    which can be constructed using other parts of the url.

   *
   * ```javascript
   * // node.js, "classic" way:
   * var MarkdownIt = require('markdown-it'),
   *     md = new MarkdownIt();
   * var result = md.render('# markdown-it rulezz!');

   * // node.js, the same, but with sugar:

   *
   * // browser without AMD, added to "window" on script load
   * // Note, there are no dash.
   * var md = window.markdownit();
   * var result = md.render('# markdown-it rulezz!');
   * ```
   *
   * Single line rendering, without paragraph wrap:

   * var md = require('markdown-it')();
   * var result = md.renderInline('__markdown-it__ rulezz!');
   * ```
   **/
  /**
   * new MarkdownIt([presetName, options])
   * - presetName (String): optional, `commonmark` / `zero`
   * - options (Object)
   *
   * Creates parser instanse with given config. Can be called without `new`.
   *
   * ##### presetName
   *
   * MarkdownIt provides named presets as a convenience to quickly
   * enable/disable active syntax rules and options for common use cases.
   *
   * - ["commonmark"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/commonmark.mjs) -
   *   configures parser to strict [CommonMark](http://commonmark.org/) mode.
   * - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.mjs) -
   *   similar to GFM, used when no preset name given. Enables all available rules,
   *   but still without html, typographer & autolinker.
   * - ["zero"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/zero.mjs) -
   *   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.mjs) +
   *   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`. Highlighter function for fenced code blocks.
   *   Highlighter `function (str, lang)` should return escaped HTML. It can also
   *   return empty string if the source was not changed and should be escaped
   *   externaly. 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>` or `<code>`):
   *
   * ```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><code class="hljs">' +
   *                hljs.highlight(str, { language: lang, ignoreIllegals: true }).value +
   *                '</code></pre>';
   *       } catch (__) {}
   *     }
   *
   *     return '<pre><code class="hljs">' + md.utils.escapeHtml(str) + '</code></pre>';
   *   }
   * });
   * ```
