Package Exports

markdown-it-highlightjs
markdown-it-highlightjs/core
markdown-it-highlightjs/core.js
markdown-it-highlightjs/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (markdown-it-highlightjs) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

markdown-it-highlightjs

Preset to use highlight.js with markdown-it.

Usage

const md = require('markdown-it')()
  .use(require('markdown-it-highlightjs'), opts)

// All code blocks will be highlighted.

The opts object can contain:

Name	Type	Description	Default
`auto`	boolean	Whether to automatically detect language if not specified.	`true`
`code`	boolean	Whether to add the `hljs` class to raw code blocks (not fenced blocks).	`true`
`register`	object	Register other languages which are not included in the standard pack.	`null`
`inline`	boolean	Whether to highlight inline code.	`false`
`hljs`	object	Provide the instance of highlight.js to use for highlighting	`require('highlight.js')`
`ignoreIllegals`	boolean	Forces highlighting to finish even in case of detecting illegal syntax for the language instead of throwing an exception.	`true`

Register languages

const md = require('markdown-it')()
  .use(require('markdown-it-highlightjs'), {
    register: {
      cypher: require('highlightjs-cypher')
    }
  })

Inline code highlighting

You can enable inline code highlighting by setting inline to true:

const md = require('markdown-it')()
  .use(require('markdown-it-highlightjs'), { inline: true })

You can specify the language for inline code using Pandoc syntax:

`x=4`{.js}

Or kramdown IAL syntax:

`x=4`{:.js}

If you do not specify a language, then highlight.js will attempt to guess the language if auto is true (which it is by default).

Usage with markdown-it-attrs

If you use markdown-it-attrs, make sure to include it after markdown-it-highlightjs if you want inline code highlighting to work:

const md = require('markdown-it')()
  .use(require('markdown-it-highlightjs'), { inline: true })
  .use(require('markdown-it-attrs'))

Provide the highlight.js instance

You can specify the hljs option to override the default highlight.js instance with your own:

const hljs = require('highlight.js/lib/core')

hljs.registerLanguage(
  'javascript',
  require('highlight.js/lib/languages/javascript')
)

const md = require('markdown-it')()
  .use(require('markdown-it-highlightjs'), { hljs })

Core plugin

You may import the core markdown-it-highlightjs plugin directly, without any default options. You must specify an instance of highlight.js for the hljs option.

const hljs = require('highlight.js/lib/core')

const md = require('markdown-it')()
  .use(require('markdown-it-highlightjs/core'), { hljs })
