// 1. No leading slash in paths,

// 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.

**/
/**
* 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.js) -
* configures parser to strict [CommonMark](http://commonmark.org/) mode.
* - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.js) -
* 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.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`. 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>`):
*
* ```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>';
* }
* });
* ```
