|
|
// 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.

/**
|
|
* class MarkdownIt
|
|
*
|
|
* Main parser/renderer class.
|
|
*
|
|
* ##### Usage
|
|
*
|
|
* ```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:
|
|
* var md = require('markdown-it')();
|
|
* var result = md.render('# markdown-it rulezz!');
|
|
*
|
|
* // 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:
|
|
*
|
|
* ```javascript
|
|
* 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.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>';
|
|
* }
|

* });
