# Table of contents

You can use the `Toc` component to generate a table of contents for your slides:

```html
<Toc minDepth="1" maxDepth="1"></Toc>
```

The title will be inferred from your slide content, or you can override it with `title` and `level` in your frontmatter.

::right::

<Toc v-click minDepth="1" maxDepth="2"></Toc>

# Code

Use code snippets and get the highlighting directly, and even types hover!

```ts {all|5|7|7-8|10|all} twoslash
// TwoSlash enables TypeScript hover information
// and errors in markdown code blocks
// More at https://shiki.style/packages/twoslash

import { computed, ref } from 'vue'

const count = ref(0)
const doubled = computed(() => count.value * 2)

doubled.value = 2
```

<arrow v-click="[4, 5]" x1="350" y1="310" x2="195" y2="334" color="#953" width="2" arrowSize="1" />

<!-- This allow you to embed external code blocks -->
<<< @/snippets/external.ts#snippet

<!-- Footer -->

<!--
Notes can also sync with clicks

[click] This will be highlighted after the first click

[click] Highlighted with `count = ref(0)`

# Shiki Magic Move

Powered by [shiki-magic-move](https://shiki-magic-move.netlify.app/), Slidev supports animations across multiple code snippets.

Add multiple code blocks and wrap them with <code>````md magic-move</code> (four backticks) to enable the magic move. For example:

````md magic-move {lines: true}
```ts {*|2|*}
// step 1
const author = reactive({
  name: 'John Doe',
  books: [
    'Vue 2 - Advanced Guide',
    'Vue 3 - Basic Guide',
    'Vue 4 - The Mystery'
  ]
})
```

```ts {*|1-2|3-4|3-4,8}
// step 2
export default {
  data() {
    return {
      author: {
        name: 'John Doe',
        books: [
          'Vue 2 - Advanced Guide',
          'Vue 3 - Basic Guide',
          'Vue 4 - The Mystery'
        ]
      }
    }
  }
}
```

```ts
// step 3
export default {
  data: () => ({
    author: {
      name: 'John Doe',
      books: [
        'Vue 2 - Advanced Guide',
        'Vue 3 - Basic Guide',
        'Vue 4 - The Mystery'
      ]
    }
  })
}
```

Non-code blocks are ignored.

```vue
<!-- step 4 -->
<script setup>
const author = {
  name: 'John Doe',
  books: [
    'Vue 2 - Advanced Guide',
    'Vue 3 - Basic Guide',
    'Vue 4 - The Mystery'
  ]
}
</script>
```
````

# Components

<div grid="~ cols-2 gap-4">
<div>

You can use Vue components directly inside your slides.

We have provided a few built-in components like `<Tweet/>` and `<Youtube/>` that you can use directly. And adding your custom components is also super easy.

```html
<Counter :count="10" />
```

<!-- ./components/Counter.vue -->
<Counter :count="10" m="t-4" />

Check out [the guides](https://sli.dev/builtin/components.html) for more.

</div>
<div>

```html
<Tweet id="1390115482657726468" />
```

<Tweet id="1390115482657726468" scale="0.65" />

</div>
</div>

<!--
Presenter note with **bold**, *italic*, and ~~striked~~ text.

Also, HTML elements are valid:
<div class="flex w-full">
  <span style="flex-grow: 1;">Left content</span>
  <span>Right content</span>
</div>
-->

# Themes

Slidev comes with powerful theming support. Themes can provide styles, layouts, components, or even configurations for tools. Switching between themes by just **one edit** in your frontmatter:

<div grid="~ cols-2 gap-2" m="t-2">

```yaml
---
theme: default
---
```

```yaml
---
theme: seriph
---
```

<img border="rounded" src="https://github.com/slidevjs/themes/blob/main/screenshots/theme-default/01.png?raw=true" alt="">

<img border="rounded" src="https://github.com/slidevjs/themes/blob/main/screenshots/theme-seriph/01.png?raw=true" alt="">

</div>

# Clicks Animations

You can add `v-click` to elements to add a click animation.

<div v-click>

This shows up when you click the slide:

```html
<div v-click>This shows up when you click the slide.</div>
```

</div>

<br>

<v-click>

The <span v-mark.red="3"><code>v-mark</code> directive</span>
also allows you to add
<span v-mark.circle.orange="4">inline marks</span>
, powered by [Rough Notation](https://roughnotation.com/):

```html
<span v-mark.underline.orange>inline markers</span>
```

</v-click>

<div mt-20 v-click>

# Motions

Motion animations are powered by [@vueuse/motion](https://motion.vueuse.org/), triggered by `v-motion` directive.

```html
<div
  v-motion
  :initial="{ x: -80 }"
  :enter="{ x: 0 }"
  :click-3="{ x: 80 }"
  :leave="{ x: 1000 }"
>
  Slidev
</div>
```

<div class="w-60 relative">
  <div class="relative w-40 h-40">
    <img
      v-motion
      :initial="{ x: 800, y: -100, scale: 1.5, rotate: -50 }"
      :enter="final"

<!-- vue script setup scripts can be directly used in markdown, and will only affects current page -->
<script setup lang="ts">

# Monaco Editor

Slidev provides built-in Monaco Editor support.

Add `{monaco}` to the code block to turn it into an editor:

```ts {monaco}
import { ref } from 'vue'
import { emptyArray } from './external'

const arr = ref(emptyArray(10))
```

Use `{monaco-run}` to create an editor that can execute the code directly in the slide:

```ts {monaco-run}
import { version } from 'vue'
import { emptyArray, sayHello } from './external'

sayHello()
console.log(`vue ${version}`)
console.log(emptyArray<number>(10).reduce(fib => [...fib, fib.at(-1)! + fib.at(-2)!], [1, 1]))
```
