Rehype asciimath
This plugin is inspired from rehype-katex.
Install
This package is ESM only. In Node.js (version 16+), install with npm:
npm install @widcardw/rehype-asciimathUse
Say our document input.html contains:
<p>
Lift(<code class="language-math">L</code>) can be determined by Lift Coefficient
(<code class="language-math">C_L</code>) like the following equation.
</p>
<pre><code class="language-math">
L = \frac{1}{2} \rho v^2 S C_L
</code></pre>…and our module example.js contains:
import rehypeDocument from 'rehype-document'
import rehypeKatex from 'rehype-katex'
import rehypeParse from 'rehype-parse'
import rehypeStringify from 'rehype-stringify'
import {read, write} from 'to-vfile'
import {unified} from 'unified'
const file = await unified()
.use(rehypeParse, {fragment: true})
.use(rehypeDocument, {
// Get the latest one from: <https://katex.org/docs/browser>.
css: 'https://cdn.jsdelivr.net/npm/[email protected]/dist/katex.min.css'
})
.use(rehypeKatex)
.use(rehypeStringify)
.process(await read('input.html'))
file.basename = 'output.html'
await write(file)…then running node example.js creates an output.html with:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>input</title>
<meta content="width=device-width, initial-scale=1" name="viewport">
<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/katex.min.css" rel="stylesheet">
</head>
<body>
<p>
Lift(<span class="katex"><!--…--></span>) can be determined by Lift Coefficient
(<span class="katex"><!--…--></span>) like the following equation.
</p>
<span class="katex-display"><!--…--></span>
</body>
</html>…open output.html in a browser to see the rendered math.
