p7d-markdown-it-renderer-fence

In code blocks, the <samp> tag is used with the language keywords samp, shell, and console.

To add specific styles to code blocks and display line numbers in code blocks, enclose each line in a span element and set CSS.

Use

It is assumed that you will use highlight.js and markdown-it-attrs together. It will probably work without them though.

import mdit from 'markdown-it'
import mditAttrs from 'markdown-it-attrs'
import highlightjs from 'highlihgtjs'
import mditRendererFence from '@peaceroad/markdown-it-renderer-fence'

const md = mdit({
             langPrefix: 'language-',
             highlight: (str, lang) => {
             if (lang && highlightjs.getLanguage(lang)) {
               try {
                  return highlightjs.highlight(str, { language: lang }).value
               } catch (__) {}
             }
             return ''
           }).use(mditAttrs).use(mditRendererFence)


const htmlCont = md.render('...')

It is also intended to be used in conjunction with @peaceroad/markdown-it-figure-with-p-caption.

Add span elements to display line number, and style attribute.

Add start or data-pre-start attribute by adding attributes used markdown-it-attrs.

```js {.style start="1"}
import mdit from 'markdonw-it'
const md = mdit()
md.render('Nyaan')
```

<pre><code class="language-js style" data-pre-start="1" style="counter-set:pre-line-number 1;"><span class="pre-line"><span class="hljs-keyword">import</span> mdit <span class="hljs-keyword">from</span> <span class="hljs-string">&#x27;markdonw-it&#x27;</span></span>
<span class="pre-line"><span class="hljs-keyword">const</span> md = <span class="hljs-title function_">mdit</span>()</span>
<span class="pre-line">md.<span class="hljs-title function_">render</span>(<span class="hljs-string">&#x27;Nyaan&#x27;</span>)</span>
</code></pre>
