Contoh

Parsing meta dasar

Plugin codeMeta() mem-parse string meta setelah identifier bahasa di fenced code block dan mengonversi key yang dikenali menjadi atribut data-* pada elemen <pre>:

import { compile, codeMeta } from "@unifast/node";

const md = `\`\`\`js title="app.ts"
const x = 1;
\`\`\``;

const result = compile(md, { plugins: [codeMeta()] });
console.log(result.output);
// <pre data-lang="js" data-title="app.ts"><code class="language-js">const x = 1;
// </code></pre>

Beberapa atribut meta

Anda dapat menggabungkan beberapa atribut meta seperti title, {1,3-5} untuk highlighting baris, showLineNumbers, diff, dan wordWrap:

import { compile, codeMeta } from "@unifast/node";

const md = `\`\`\`ts title="server.ts" {1,3} showLineNumbers
import express from "express";
const app = express();
app.listen(3000);
\`\`\``;

const result = compile(md, { plugins: [codeMeta()] });
// The <pre> element receives:
//   data-title="server.ts"
//   Lines 1 and 3 get data-highlighted attributes
//   showLineNumbers is recognized as a boolean flag
