markdown-it-inject-linenumbers v0.3.0

markdown-it-inject-linenumbers

Insert line numbers to support sync scrolling for the markdown-it markdown parser.

Inject the source line numbers into the final HTML. This gives you the anchor points to implement synchronized scrolling.

lorem => <p class="line" data-source-line="0">lorem</p>

Inline elements are not supported. Only the following block level elements are currently supported:

• headings
• paragraphs
• list items
• tables

This plugin was built using the markdown-it demo sync scrolling as a starting point.

Install

node.js, browser:

npm install markdown-it-inject-linenumbers --save
bower install markdown-it-inject-linenumbers --save

Use

var md = require('markdown-it')()
            .use(require('markdown-it-inject-linenumbers'));

md.render('lorem') // => '<p class="source-line" data-source-line="0">lorem</p>'

Differences in browser. If you load script directly into the page, without package system, module will add itself globally as window.markdownitInjectLinenumbers.
