Markdown 扩展

VitePress 带有内置的 Markdown 扩展。

标题锚点

标题会自动应用锚点。可以使用 markdown.anchor 选项配置锚点的渲染。

Custom anchors

To specify a custom anchor tag for a heading instead of using the auto-generated one, add a suffix to the heading:

# Using custom anchors {#my-anchor}
# Using custom anchors {#my-anchor}

This allows you to link to the heading as #my-anchor instead of the default #using-custom-anchors.

内部和外部链接都会被特殊处理。

内部链接将转换为单页导航的路由链接。此外,子目录中包含的每个 index.md 都会自动转换为 index.html,并带有相应的 URL /

例如,给定以下目录结构:

.
├─ index.md
├─ foo
│  ├─ index.md
│  ├─ one.md
│  └─ two.md
└─ bar
   ├─ index.md
   ├─ three.md
   └─ four.md
.
├─ index.md
├─ foo
│  ├─ index.md
│  ├─ one.md
│  └─ two.md
└─ bar
   ├─ index.md
   ├─ three.md
   └─ four.md

假设你现在处于 foo/one.md 文件中:

md
[Home](/) <!-- sends the user to the root index.md -->
[foo](/foo/) <!-- sends the user to index.html of directory foo -->
[foo heading](./#heading) <!-- anchors user to a heading in the foo index file -->
[bar - three](../bar/three) <!-- you can omit extension -->
[bar - three](../bar/three.md) <!-- you can append .md -->
[bar - four](../bar/four.html) <!-- or you can append .html -->
[Home](/) <!-- sends the user to the root index.md -->
[foo](/foo/) <!-- sends the user to index.html of directory foo -->
[foo heading](./#heading) <!-- anchors user to a heading in the foo index file -->
[bar - three](../bar/three) <!-- you can omit extension -->
[bar - three](../bar/three.md) <!-- you can append .md -->
[bar - four](../bar/four.html) <!-- or you can append .html -->

页面后缀

默认情况下,生成的页面和内部链接带有 .html 后缀。

外部链接带有 target="_blank" rel="noreferrer"

Frontmatter

YAML 格式的 frontmatter 开箱即用:

yaml
---
title: Blogging Like a Hacker
lang: en-US
---
---
title: Blogging Like a Hacker
lang: en-US
---

此数据将可用于页面的其余部分,以及所有自定义和主题组件。

更多信息,参见 Frontmatter

GitHub 风格的表格

输入

| Tables        |      Are      |  Cool |
| ------------- | :-----------: | ----: |
| col 3 is      | right-aligned | $1600 |
| col 2 is      |   centered    |   $12 |
| zebra stripes |   are neat    |    $1 |
| Tables        |      Are      |  Cool |
| ------------- | :-----------: | ----: |
| col 3 is      | right-aligned | $1600 |
| col 2 is      |   centered    |   $12 |
| zebra stripes |   are neat    |    $1 |

输出

TablesAreCool
col 3 isright-aligned$1600
col 2 iscentered$12
zebra stripesare neat$1

Emoji 🎉

这里你可以找到所有支持的 emoji 列表

目录表 (TOC)

输入

[[toc]]
[[toc]]

输出

可以使用 markdown.toc 选项配置 TOC 的呈现效果。

自定义容器

自定义容器可以通过它们的类型、标题和内容来定义。

默认标题

输入

md
::: info
This is an info box.
:::

::: tip
This is a tip.
:::

::: warning
This is a warning.
:::

::: danger
This is a dangerous warning.
:::

::: details
This is a details block.
:::
::: info
This is an info box.
:::

::: tip
This is a tip.
:::

::: warning
This is a warning.
:::

::: danger
This is a dangerous warning.
:::

::: details
This is a details block.
:::

输出

INFO

This is an info box.

TIP

This is a tip.

WARNING

This is a warning.

DANGER

This is a dangerous warning.

Details

This is a details block.

自定义标题

可以通过在容器的“类型”之后附加文本来设置自定义标题。

输入

md
::: danger STOP
Danger zone, do not proceed
:::

::: details Click me to view the code
```js
console.log('Hello, VitePress!')
```
:::
::: danger STOP
Danger zone, do not proceed
:::

::: details Click me to view the code
```js
console.log('Hello, VitePress!')
```
:::

输出

STOP

Danger zone, do not proceed

Click me to view the code
js
console.log('Hello, VitePress!')
console.log('Hello, VitePress!')

raw

这是一个特殊的容器,可以用来防止与 VitePress 的样式和路由冲突。这在记录组件库时特别有用。你可能还想查看 whyframe 以获得更好的隔离。

语法

md
::: raw
Wraps in a <div class="vp-raw">
:::
::: raw
Wraps in a <div class="vp-raw">
:::

vp-raw class 也可以直接用于元素。样式隔离目前是可选的:

  • 使用你喜欢的包管理器来安装需要的依赖项:

    sh
    $ npm install -D postcss postcss-prefix-selector
    $ npm install -D postcss postcss-prefix-selector
  • 创建 docs/.postcssrc.cjs 并将以下内容

    js
    module.exports = {
      plugins: {
        'postcss-prefix-selector': {
          prefix: ':not(:where(.vp-raw *))',
          includeFiles: [/vp-doc\.css/],
          transform(prefix, _selector) {
            const [selector, pseudo = ''] = _selector.split(/(:\S*)$/)
            return selector + prefix + pseudo
          }
        }
      }
    }
    module.exports = {
      plugins: {
        'postcss-prefix-selector': {
          prefix: ':not(:where(.vp-raw *))',
          includeFiles: [/vp-doc\.css/],
          transform(prefix, _selector) {
            const [selector, pseudo = ''] = _selector.split(/(:\S*)$/)
            return selector + prefix + pseudo
          }
        }
      }
    }

代码块中的语法高亮

VitePress 使用 Shiki 在 Markdown 代码块中使用彩色文本实现语法高亮。Shiki 支持多种编程语言。你需要做的就是将有效的语言别名附加到代码块的开头:

输入

```js
export default {
  name: 'MyComponent',
  // ...
}
```
```js
export default {
  name: 'MyComponent',
  // ...
}
```
```html
<ul>
  <li v-for="todo in todos" :key="todo.id">
    {{ todo.text }}
  </li>
</ul>
```
```html
<ul>
  <li v-for="todo in todos" :key="todo.id">
    {{ todo.text }}
  </li>
</ul>
```

输出

js
export default {
  name: 'MyComponent'
  // ...
}
export default {
  name: 'MyComponent'
  // ...
}
html
<ul>
  <li v-for="todo in todos" :key="todo.id">
    {{ todo.text }}
  </li>
</ul>
<ul>
  <li v-for="todo in todos" :key="todo.id">
    {{ todo.text }}
  </li>
</ul>

在 Shiki 的代码仓库中,可以找到合法的编程语言列表

还可以全局配置中自定义语法高亮主题。有关详细信息,参见 markdown 选项得到更多信息。

在代码块中实现行高亮

输入

```js{4}
export default {
  data () {
    return {
      msg: 'Highlighted!'
    }
  }
}
```
```js{4}
export default {
  data () {
    return {
      msg: 'Highlighted!'
    }
  }
}
```

输出

js
export default {
  data () {
    return {
      msg: 'Highlighted!'
    }
  }
}
export default {
  data () {
    return {
      msg: 'Highlighted!'
    }
  }
}

除了单行之外,还可以指定多个单行、多行,或两者均指定:

  • 多行:例如 {5-8}{3-10}{10-17}
  • 多个单行:例如 {4,7,9}
  • 多行与单行:例如 {4,7-13,16,23-27,40}

输入

```js{1,4,6-8}
export default { // Highlighted
  data () {
    return {
      msg: `Highlighted!
      This line isn't highlighted,
      but this and the next 2 are.`,
      motd: 'VitePress is awesome',
      lorem: 'ipsum'
    }
  }
}
```
```js{1,4,6-8}
export default { // Highlighted
  data () {
    return {
      msg: `Highlighted!
      This line isn't highlighted,
      but this and the next 2 are.`,
      motd: 'VitePress is awesome',
      lorem: 'ipsum'
    }
  }
}
```

输出

js
export default { // Highlighted
  data () {
    return {
      msg: `Highlighted!
      This line isn't highlighted,
      but this and the next 2 are.`,
      motd: 'VitePress is awesome',
      lorem: 'ipsum',
    }
  }
}
export default { // Highlighted
  data () {
    return {
      msg: `Highlighted!
      This line isn't highlighted,
      but this and the next 2 are.`,
      motd: 'VitePress is awesome',
      lorem: 'ipsum',
    }
  }
}

也可以使用 // [!code hl] 注释实现行高亮。

输入

```js
export default {
  data () {
    return {
      msg: 'Highlighted!' // [!code  hl]
    }
  }
}
```
```js
export default {
  data () {
    return {
      msg: 'Highlighted!' // [!code  hl]
    }
  }
}
```

输出

js
export default {
  data() {
    return {
      msg: 'Highlighted!' 
    }
  }
}
export default {
  data() {
    return {
      msg: 'Highlighted!' 
    }
  }
}

代码块中聚焦

在某一行上添加 // [!code focus] 注释将聚焦它并模糊代码的其他部分。

此外,可以使用 // [!code focus:<lines>] 定义要聚焦的行数。

输入

!code 后面只需要一个空格,为了展示原始的代码而不被实际渲染,这里有两个空格:

```js
export default {
  data () {
    return {
      msg: 'Focused!' // [!code  focus]
    }
  }
}
```
```js
export default {
  data () {
    return {
      msg: 'Focused!' // [!code  focus]
    }
  }
}
```

输出

js
export default {
  data() {
    return {
      msg: 'Focused!' 
    }
  }
}
export default {
  data() {
    return {
      msg: 'Focused!' 
    }
  }
}

代码块中的颜色差异

在某一行添加 // [!code --]// [!code ++] 注释将会为该行创建 diff,同时保留代码块的颜色。

输入

!code 后面只需要一个空格,为了展示原始的代码而不被实际渲染,这里有两个空格。

```js
export default {
  data () {
    return {
      msg: 'Removed' // [!code  --]
      msg: 'Added' // [!code  ++]
    }
  }
}
```
```js
export default {
  data () {
    return {
      msg: 'Removed' // [!code  --]
      msg: 'Added' // [!code  ++]
    }
  }
}
```

输出

js
export default {
  data () {
    return {
      msg: 'Removed' 
      msg: 'Added' 
    }
  }
}
export default {
  data () {
    return {
      msg: 'Removed' 
      msg: 'Added' 
    }
  }
}

高亮“错误”和“警告”

在某一行添加 // [!code warning]// [!code error] 注释将会为该行相应的着色。

输入

!code 后面只需要一个空格,为了展示原始的代码而不被实际渲染,这里有两个空格。

```js
export default {
  data () {
    return {
      msg: 'Error', // [!code  error]
      msg: 'Warning' // [!code  warning]
    }
  }
}
```
```js
export default {
  data () {
    return {
      msg: 'Error', // [!code  error]
      msg: 'Warning' // [!code  warning]
    }
  }
}
```

输出

js
export default {
  data() {
    return {
      msg: 'Error', 
      msg: 'Warning' 
    }
  }
}
export default {
  data() {
    return {
      msg: 'Error', 
      msg: 'Warning' 
    }
  }
}

行号

你可以通过以下配置为每个代码块启用行号:

js
export default {
  markdown: {
    lineNumbers: true
  }
}
export default {
  markdown: {
    lineNumbers: true
  }
}

查看 markdown 选项 获取更多信息。

你可以在你的代码块中添加 :line-numbers / :no-line-numbers 标记来覆盖在配置中的设置。

输入

md
```ts {1}
// line-numbers is disabled by default
const line2 = 'This is line 2'
const line3 = 'This is line 3'
```

```ts:line-numbers {1}
// line-numbers is enabled
const line2 = 'This is line 2'
const line3 = 'This is line 3'
```
```ts {1}
// line-numbers is disabled by default
const line2 = 'This is line 2'
const line3 = 'This is line 3'
```

```ts:line-numbers {1}
// line-numbers is enabled
const line2 = 'This is line 2'
const line3 = 'This is line 3'
```

输出

ts
// line-numbers is disabled by default
const line2 = 'This is line 2'
const line3 = 'This is line 3'
// line-numbers is disabled by default
const line2 = 'This is line 2'
const line3 = 'This is line 3'
ts
// line-numbers is enabled
const line2 = 'This is line 2'
const line3 = 'This is line 3'
// line-numbers is enabled
const line2 = 'This is line 2'
const line3 = 'This is line 3'

导入代码片段

你可以通过下面的语法来从现有文件中导入代码片段:

md
<<< @/filepath
<<< @/filepath

此语法同时支持行高亮

md
<<< @/filepath{highlightLines}
<<< @/filepath{highlightLines}

输入

md
<<< @/snippets/snippet.js{2}
<<< @/snippets/snippet.js{2}

Code file

js
export default function () {
  // ..
}
export default function () {
  // ..
}

输出

js
export default function () {
  // ..
}
export default function () {
  // ..
}

TIP

@ 的值对应于源代码根目录,默认情况下是 VitePress 项目根目录,除非配置了 srcDir。或者你也可以从相对路径导入:

md
<<< ../snippets/snippet.js
<<< ../snippets/snippet.js

你也可以使用 VS Code region 来只包含代码文件的相应部分。你可以在文件目录后面的 # 符号后提供一个自定义的区域名:

输入

md
<<< @/snippets/snippet-with-region.js#snippet{1}
<<< @/snippets/snippet-with-region.js#snippet{1}

Code file

js
// #region snippet
function foo() {
  // ..
}
// #endregion snippet

export default foo
// #region snippet
function foo() {
  // ..
}
// #endregion snippet

export default foo

输出

js
function foo() {
  // ..
}
function foo() {
  // ..
}

你也可以像这样在大括号内({})指定语言:

md
<<< @/snippets/snippet.cs{c#}

<!-- with line highlighting: -->

<<< @/snippets/snippet.cs{1,2,4-6 c#}

<!-- with line numbers: -->

<<< @/snippets/snippet.cs{1,2,4-6 c#:line-numbers}
<<< @/snippets/snippet.cs{c#}

<!-- with line highlighting: -->

<<< @/snippets/snippet.cs{1,2,4-6 c#}

<!-- with line numbers: -->

<<< @/snippets/snippet.cs{1,2,4-6 c#:line-numbers}

如果无法从文件拓展名推测出源语言,这将会很有帮助

代码组

你可以像这样对多个代码块进行分组:

输入

md
::: code-group

```js [config.js]
/**
 * @type {import('vitepress').UserConfig}
 */
const config = {
  // ...
}

export default config
```

```ts [config.ts]
import type { UserConfig } from 'vitepress'

const config: UserConfig = {
  // ...
}

export default config
```

:::
::: code-group

```js [config.js]
/**
 * @type {import('vitepress').UserConfig}
 */
const config = {
  // ...
}

export default config
```

```ts [config.ts]
import type { UserConfig } from 'vitepress'

const config: UserConfig = {
  // ...
}

export default config
```

:::

输出

js
/**
 * @type {import('vitepress').UserConfig}
 */
const config = {
  // ...
}

export default config
/**
 * @type {import('vitepress').UserConfig}
 */
const config = {
  // ...
}

export default config
ts
import type { UserConfig } from 'vitepress'

const config: UserConfig = {
  // ...
}

export default config
import type { UserConfig } from 'vitepress'

const config: UserConfig = {
  // ...
}

export default config

你也可以在代码组中导入代码片段

输入

md
::: code-group

<!-- filename is used as title by default -->

<<< @/snippets/snippet.js

<!-- you can provide a custom one too -->

<<< @/snippets/snippet-with-region.js#snippet{1,2 ts:line-numbers} [snippet with region]

:::
::: code-group

<!-- filename is used as title by default -->

<<< @/snippets/snippet.js

<!-- you can provide a custom one too -->

<<< @/snippets/snippet-with-region.js#snippet{1,2 ts:line-numbers} [snippet with region]

:::

输出

js
export default function () {
  // ..
}
export default function () {
  // ..
}
ts
function foo() {
  // ..
}
function foo() {
  // ..
}

包含 markdown 文件

你可以像这样在一个 markdown 文件中包含另一个 markdown 文件,甚至是内嵌的。

TIP

你也可以使用 @,它的值对应于源代码根目录,默认情况下是 VitePress 项目根目录,除非配置了 srcDir

例如,你可以这样用相对路径包含 Markdown 文件:

输入

md
# Docs {#docs}

## Basics {#basics}

<!--@include: ./parts/basics.md-->
# Docs {#docs}

## Basics {#basics}

<!--@include: ./parts/basics.md-->

另一个文件 (parts/basics.md)

md
Some getting started stuff.

### Configuration {#configuration}

Can be created using `.foorc.json`.
Some getting started stuff.

### Configuration {#configuration}

Can be created using `.foorc.json`.

等价代码

md
# Docs {#docs}

## Basics {#basics}

Some getting started stuff.

### Configuration {#configuration}

Can be created using `.foorc.json`.
# Docs {#docs}

## Basics {#basics}

Some getting started stuff.

### Configuration {#configuration}

Can be created using `.foorc.json`.

It also supports selecting a line range:

Input

md
# Docs

## Basics

<!--@include: ./parts/basics.md{3,}-->
# Docs

## Basics

<!--@include: ./parts/basics.md{3,}-->

Part file (parts/basics.md)

md
Some getting started stuff.

### Configuration

Can be created using `.foorc.json`.
Some getting started stuff.

### Configuration

Can be created using `.foorc.json`.

Equivalent code

md
# Docs

## Basics

### Configuration

Can be created using `.foorc.json`.
# Docs

## Basics

### Configuration

Can be created using `.foorc.json`.

The format of the selected line range can be: {3,}, {,10}, {1,10}

WARNING

如果你指定的文件不存在,这将不会产生错误。因此,在使用这个功能的时候请保证内容按预期呈现。

高级配置

VitePress 使用 markdown-it 作为 Markdown 渲染器。上面提到的很多拓展功能都是通过自定义插件实现的。你可以使用 .vitepress/config.js 中的 markdown 选项来进一步自定义 markdown-it 实例。

js
import markdownItAnchor from 'markdown-it-anchor'
import markdownItFoo from 'markdown-it-foo'

module.exports = {
  markdown: {
    // options for markdown-it-anchor
    // https://github.com/valeriangalliat/markdown-it-anchor#usage
    anchor: {
      permalink: markdownItAnchor.permalink.headerLink()
    },

    // options for @mdit-vue/plugin-toc
    // https://github.com/mdit-vue/mdit-vue/tree/main/packages/plugin-toc#options
    toc: { level: [1, 2] },

    config: (md) => {
      // use more markdown-it plugins!
      md.use(markdownItFoo)
    }
  }
}
import markdownItAnchor from 'markdown-it-anchor'
import markdownItFoo from 'markdown-it-foo'

module.exports = {
  markdown: {
    // options for markdown-it-anchor
    // https://github.com/valeriangalliat/markdown-it-anchor#usage
    anchor: {
      permalink: markdownItAnchor.permalink.headerLink()
    },

    // options for @mdit-vue/plugin-toc
    // https://github.com/mdit-vue/mdit-vue/tree/main/packages/plugin-toc#options
    toc: { level: [1, 2] },

    config: (md) => {
      // use more markdown-it plugins!
      md.use(markdownItFoo)
    }
  }
}

请查看配置参考:站点配置来获取完整的可配置属性列表。
