    • 

  • 

      

    • 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.
    • 

  • 

  • 


    • 

  • configures parser to strict CommonMark mode.
    • 

  • 


    • 

  • similar to GFM, used when no preset name given. Enables all available rules,
    • 

  • but still without html, typographer & autolinker.
    • 

  • 


    • 

  • 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
    

    • 

  • 

  • 

    

    • 

  • // 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
    

    • 

  • 

  • 

    

    • 

  • var hljs = require('highlight.js') // https://highlightjs.org/
    • 

  • 

  • var md = require('markdown-it')({
    •

// 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.
