MetaPost - a language grammar for highlight.js

October 13, 2024 ยท View on GitHub

MetaPost refers to both a programming language and the interpreter of the MetaPost programming language. Both are derived from Donald Knuth's Metafont language and interpreter. MetaPost produces vector graphic diagrams from a geometric/algebraic description. The language shares Metafont's declarative syntax for manipulating lines, curves, points and geometric transformations.

Usage

Simply include the Highlight.js library in your webpage or Node app, then load this module.

Static website or simple usage

Simply load the module after loading Highlight.js. You'll use the minified version found in the dist directory. This module is just a CDN build of the language, so it will register itself as the Javascript is loaded.

<script type="text/javascript" src="/path/to/highlight.min.js"></script>
<script type="text/javascript" charset="UTF-8"
  src="/path/to/highlightjs-metapost/dist/metapost.min.js"></script>
<script type="text/javascript">
  hljs.highlightAll();
</script>

Using directly from the UNPKG CDN

<script type="text/javascript"
  src="https://unpkg.com/highlightjs-cypher/dist/metapost.min.js"></script>

With Node or another build system

If you're using Node / Webpack / Rollup / Browserify, etc, simply require the language module, then register it with Highlight.js.

var hljs = require('highlightjs');
var hljsMetapost = require('highlightjs-metapost');

hljs.registerLanguage("metapost", hljsMetapost);
hljs.highlightAll();

React

You need to import both Highlight.js and third-party language like Metapost:

import React, {Component} from 'react'
import 'highlight.js/scss/darcula.scss' # your favourite theme
import metapost from './metapost'
import hljs from 'highlight.js'
hljs.registerLanguage('metapost', metapost);

class Highlighter extends Component
{
  constructor(props)
  {
    super(props);
    hljs.highlightAll();
  }

  render()
  {
    let {children} = this.props;
    return
    {
      <pre ref={(node) => this.node = node}>
        <code className="metapost">
          {children}
        </code>
      </pre>
    }
  }
}

export default Highlighter;
