  "body": "```ts\nimport { codeMeta } from \"@unifast/node\";\n```\n\n## 签名\n\n```ts\nfunction codeMeta(): UnifastPlugin\n```\n\n## 参数\n\n无。\n\n## 用法\n\n```ts\nimport { compile, codeMeta } from \"@unifast/node\";\n\nconst md = `\\`\\`\\`js title=\"example.js\"\nconsole.log(\"hello\");\n\\`\\`\\``;\n\nconst result = compile(md, {\n  plugins: [codeMeta()],\n});\n// The <pre> element gets data-title=\"example.js\"\n```\n\n## 示例\n\n### 基础 meta 解析\n\n`codeMeta()` 插件会解析围栏代码块中语言标识之后的 meta 字符串，并将可识别的键转换为 `<pre>` 元素上的 `data-*` 属性：\n\n```ts\nimport { compile, codeMeta } from \"@unifast/node\";\n\nconst md = `\\`\\`\\`js title=\"app.ts\"\nconst x = 1;\n\\`\\`\\``;\n\nconst result = compile(md, { plugins: [codeMeta()] });\nconsole.log(result.output);\n// <pre data-lang=\"js\" data-title=\"app.ts\"><code class=\"language-js\">const x = 1;\n// </code></pre>\n```\n\n### 多个 meta 属性\n\n你可以组合使用多种 meta 属性，例如 `title`、用于行高亮的 `{1,3-5}`、`showLineNumbers`、`diff` 和 `wordWrap`：\n\n```ts\nimport { compile, codeMeta } from \"@unifast/node\";\n\nconst md = `\\`\\`\\`ts title=\"server.ts\" {1,3} showLineNumbers\nimport express from \"express\";\nconst app = express();\napp.listen(3000);\n\\`\\`\\``;\n\nconst result = compile(md, { plugins: [codeMeta()] });\n// The <pre> element receives:\n//   data-title=\"server.ts\"\n//   Lines 1 and 3 get data-highlighted attributes\n//   showLineNumbers is recognized as a boolean flag\n```",
