Workflow

🎯 CRITICAL: First determine which mode the user needs, then follow the appropriate workflow.

Decision: Which Mode?

Ask the user:

您需要创建什么类型的演示文稿项目？

1. **单个演示文稿** - 创建一个独立的HTML文件
   - 适合：快速分享、一次性演讲、嵌入文档
   
2. **演示文稿仓库** - 创建一个完整的演示文稿管理系统
   - 适合：多个演示文稿、团队库、GitHub Pages发布、演示文稿作品集

请选择：[1] 单个演示文稿  [2] 演示文稿仓库

---

Workflow A: Single Presentation Mode

This workflow uses an interactive, question-guided approach. Always ask questions to understand the user's needs before generating any code.

Step 1: Initial Discovery (Ask Questions)

ALWAYS start by asking these questions to the user:

让我为您创建一个精彩的演示文稿！首先，我需要了解一些信息：

📌 **内容方面：**
1. 演示文稿的主题是什么？
2. 目标受众是谁？（客户、团队、学生、投资人？）
3. 核心信息是什么？（3-5个主要观点）
4. 预计需要多少张幻灯片？（快速演讲5-10张 / 标准演示15-25张 / 长篇讲座30+张）

🎨 **视觉风格：**
5. 您偏好什么视觉风格？
   - □ 专业商务（深色、简约）
   - □ 创意活泼（彩色、动感）
   - □ 极简主义（留白、聚焦）
   - □ 技术感（代码、图表）
   
6. 是否有品牌颜色要求？（如果有，请提供色值）

✨ **动画效果：**
7. 您需要什么程度的动画效果？
   - □ 基础（简单淡入淡出）
   - □ 中等（逐步显示要点）
   - □ 高级（元素变换、数据可视化动画）

🎤 **特殊功能：**
8. 是否需要以下功能？
   - □ 演讲者备注（用于演讲提示）
   - □ 代码高亮显示
   - □ 数学公式支持
   - □ 垂直嵌套幻灯片（章节内子主题）

Wait for user responses before proceeding to Step 2.

Step 2: Content Planning (Collaborative Structure)

Based on user's answers, propose a slide structure and ask for confirmation:

根据您的需求，我建议以下结构：

📋 **建议的幻灯片结构：**

1. 标题页 - [主题]
2. 议程 - 本次演示的内容概览
3. 【第一部分】章节分隔符 - [第一个主要话题]
   ├─ 4. [子主题1]
   ├─ 5. [子主题2]
   └─ 6. [子主题3]
4. 【第二部分】章节分隔符 - [第二个主要话题]
   ├─ 7. [子主题1]
   └─ 8. [子主题2]
5. 总结 - 核心要点回顾
6. 结束页 - 致谢与问答

这个结构符合您的需求吗？是否需要调整？

Wait for user confirmation or adjustment before proceeding.

Step 3: Animation & Feature Selection

Ask about specific animation and feature requirements:

现在让我们确定动画和交互细节：

🎭 **动画配置：**
1. 幻灯片切换效果偏好？
   - slide（滑动，默认）
   - fade（淡入淡出）
   - zoom（缩放）
   - convex（凸出）
   - concave（凹陷）

2. 要点列表是否需要逐条显示？（推荐）
   ☐ 是，要点逐条淡入
   ☐ 否，一次全部显示

3. 是否需要特殊动画？
   ☐ 元素自动变换（数字变化、图形变形）
   ☐ 高亮强调（当前要点高亮）
   ☐ 代码逐行显示

📝 **演讲者功能：**
4. 每张幻灯片是否需要演讲者备注？
   ☐ 是，我会提供每页的讲解提示
   ☐ 否，仅幻灯片内容

选择您需要的选项，我将据此创建演示文稿。

Wait for user's selections.

Step 4: Read the Template

CRITICAL: Before writing any code, read the Reveal.js template file:

templates/viewer-reveal.html

This template contains:

• ✅ Reveal.js integration: CDN links to Reveal.js 5.x core and plugins
• ✅ Theme system: CSS custom properties for brand colors
• ✅ Layout classes: Pre-built styles for all 6 layout types
• ✅ Configuration object: PRESENTATION_CONFIG with all Reveal.js options
• ✅ Plugin setup: Code highlighting, Markdown, Math, Notes, Zoom, Search
• ✅ Full API access: Complete Reveal.js API exposed via window.PresentationAPI

The template is your foundation. Copy it and customize the content sections.

Step 5: Generate Slide Content

Create slides using standard HTML <section> tags within .reveal .slides:

Basic structure:

<div class="reveal">
    <div class="slides">
        <!-- Each <section> is a slide -->
        <section class="slide-title">
            <h1>Title</h1>
        </section>
        
        <section class="slide-content">
            <h2>Content</h2>
            <ul>
                <li class="fragment">Point 1</li>
                <li class="fragment">Point 2</li>
            </ul>
            
            <!-- Speaker notes -->
            <aside class="notes">
                This is what you'll say...
            </aside>
        </section>
        
        <!-- Nested slides (vertical navigation) -->
        <section>
            <section><h2>Main Topic</h2></section>
            <section><h3>Subtopic 1</h3></section>
            <section><h3>Subtopic 2</h3></section>
        </section>
    </div>
</div>

Fragment animations (progressive reveal):

<ul>
    <li class="fragment">Appears first</li>
    <li class="fragment">Appears second</li>
    <li class="fragment fade-in">Fades in</li>
    <li class="fragment fade-up">Slides up</li>
    <li class="fragment highlight-red">Highlights in red</li>
</ul>

Available fragment animations:

• fragment - Basic fade in
• fragment fade-in - Fade in
• fragment fade-out - Fade out
• fragment fade-up - Slide up
• fragment fade-down - Slide down
• fragment grow - Grow larger
• fragment shrink - Shrink smaller
• fragment highlight-red - Highlight in red
• fragment highlight-blue - Highlight in blue
• fragment highlight-current-blue - Highlight current item

Step 6: Configure Presentation

Update the PRESENTATION_CONFIG object:

const PRESENTATION_CONFIG = {
    // Basic info
    title: "Your Presentation Title",
    author: "Your Name",
    date: "2026年2月3日",
    
    // Theme colors
    theme: {
        primary: "#2E86AB",      // Main color
        secondary: "#A23B72",    // Secondary color
        accent: "#F18F01",       // Accent color
        background: "#0a0a0a",   // Background
        text: "#ffffff",         // Text color
        textMuted: "#cccccc"     // Muted text
    },
    
    // Reveal.js options
    revealOptions: {
        transition: 'slide',      // slide/fade/zoom/convex/concave
        controls: true,           // Show arrow controls
        progress: true,           // Show progress bar
        center: true,             // Vertical centering
        slideNumber: 'c/t',       // Show slide numbers
        hash: true,               // URL routing
        
        // Animation speed
        transitionSpeed: 'default', // default/fast/slow
        
        // Auto-advance (0 = disabled)
        autoSlide: 0,
        
        // Plugins (always included)
        plugins: [
            RevealMarkdown,
            RevealHighlight,
            RevealNotes,
            RevealZoom,
            RevealSearch,
            RevealMath.KaTeX
        ]
    }
};

Full configuration options: https://revealjs.com/config/

Step 7: Add Advanced Features (Optional)

Speaker notes (press S to open):

<section>
    <h2>Slide Title</h2>
    <p>Public content...</p>
    
    <aside class="notes">
        Remember to emphasize this point.
        Mention the case study here.
        Time: 2 minutes on this slide.
    </aside>
</section>

Code highlighting with line numbers:

<section>
    <h2>Code Example</h2>
    <pre><code class="language-javascript" data-trim data-line-numbers="1-2|4-6">
function hello(name) {
    console.log(`Hello, ${name}!`);
}

// Usage
hello('World');
    </code></pre>
</section>

Math equations (KaTeX):

<section>
    <h2>Mathematical Formula</h2>
    <p>The quadratic formula:</p>
    <p>$$x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}$$</p>
</section>

Auto-animate (element transitions):

<section data-auto-animate>
    <h2 style="margin-top: 100px;">Animate</h2>
</section>
<section data-auto-animate>
    <h2 style="margin-top: 400px; color: red;">Animate</h2>
</section>

Custom backgrounds:

<section data-background-color="#ff0000">
    <h2>Red Background</h2>
</section>

<section data-background-image="url.jpg">
    <h2>Image Background</h2>
</section>

<section data-background-gradient="linear-gradient(to bottom, #283b95, #17b2c3)">
    <h2>Gradient Background</h2>
</section>

Step 8: Validate and Test

Generate the HTML file and verify:

1. Open in browser - File loads correctly
2. Navigate all slides - Arrow keys work (→ = next, ↓ = nested)
3. Test fragments - Progressive reveals work
4. Speaker view - Press S (opens in new window)
5. Overview mode - Press ESC (thumbnail view)
6. Fullscreen - Press F
7. Search - Press Ctrl+Shift+F
8. Zoom - Alt+Click to zoom in
9. Help overlay - Press ? for shortcuts

Common issues:

• Slides not showing: Check <section> tags are inside .reveal .slides
• Fragments not working: Ensure class="fragment" is set
• Speaker notes not appearing: Press S, check <aside class="notes">
• Code not highlighted: Verify class="language-xxx" on <code>

Step 9: Deliver with Instructions

Provide the HTML file with clear instructions:

File name: [topic]-presentation.html

Output location: Save the HTML file to the docs/ directory in your project

Usage instructions:

🎯 打开方式：在任何现代浏览器中打开此 HTML 文件

⌨️ 快捷键：

Workflow B: Presentation Repository Mode

Use this workflow when the user wants to manage multiple presentations with GitHub Pages deployment.

Step 1: Repository Initialization

Ask initial questions:

让我为您创建一个演示文稿管理仓库！首先：

📁 **仓库基本信息：**
1. 仓库名称是什么？（例如：my-presentations, tech-talks, company-slides）
2. 仓库放在哪个目录？（默认：当前工作目录）
3. 是否要立即创建示例演示文稿？（推荐：是）

📋 **初始内容：**
4. 如果创建示例，主题是什么？
5. 您的GitHub用户名是什么？（用于GitHub Pages配置）

Wait for responses.

Step 2: Create Repository Structure

Create the complete repository structure:

1. Create directories:

mkdir -p {repo-name}/{presentations,templates,scripts,assets/css}

2. Copy template files:

   • scripts/generate-index.js - Index generation script
   • templates/presentation-template.html - Presentation template
   • templates/metadata-template.json - Metadata template
   • templates/index-template.html - Index page template
   • templates/README-template.md - README template
   • templates/.gitignore-template - .gitignore template
   • templates/custom-css-template.css - Custom CSS template

3. Generate package.json with build scripts

4. Create .nojekyll for GitHub Pages

5. Create assets/css/custom.css for shared styles

6. Create README.md with usage instructions

Step 3: Optional - Create Example Presentation

If user requested an example:

1. Create presentations/example-presentation/ directory
2. Copy and customize presentation-template.html → index.html
3. Create metadata.json with provided information
4. Create or generate placeholder thumbnail.png (800x600)

Step 4: Initialize and Build

cd {repo-name}
npm install
npm run build

This generates the initial index.html with the presentation gallery.

Step 5: GitHub Pages Setup Instructions

Provide step-by-step deployment instructions:

📚 仓库已创建！现在设置GitHub Pages：

**1. 初始化Git并推送到GitHub：**
```bash
cd {repo-name}
git init
git add .
git commit -m "Initial commit: Presentation repository"
git remote add origin https://github.com/{username}/{repo-name}.git
git push -u origin main

2. 配置GitHub Pages：

1. 访问 https://github.com/{username}/{repo-name}/settings/pages
2. Source: Deploy from a branch
3. Branch: main / (root)
4. 点击 Save

3. 等待部署（约1-3分钟） 您的演示文稿集合将在以下地址可访问： https://{username}.github.io/{repo-name}/

4. 添加新的演示文稿：

# 创建新演示文稿目录
mkdir presentations/my-new-talk

# 复制模板
cp templates/presentation-template.html presentations/my-new-talk/index.html
cp templates/metadata-template.json presentations/my-new-talk/metadata.json

# 编辑内容和元数据
# 然后重新生成索引并部署
npm run deploy

本地预览：

npm run dev

访问 http://localhost:8080 查看索引页

### Step 6: Optional - Create GitHub Action for Auto-Deploy

**Ask user:**

是否要创建GitHub Action自动部署？ 这样每次push都会自动重新生成索引页。

[是] [否]

If yes, create `.github/workflows/deploy.yml`:

```yaml
name: Generate Index and Deploy

on:
  push:
    branches: [ main ]
  workflow_dispatch:

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    
    steps:
      - name: Checkout
        uses: actions/checkout@v3
      
      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: '18'
      
      - name: Install dependencies
        run: npm install
      
      - name: Generate index
        run: npm run build
      
      - name: Commit and push if changed

reveal.up();              // Navigate up (nested)

State management:

// Get current state
const state = reveal.getState();
console.log(state);  // {indexh: 2, indexv: 0, indexf: 1}

// Get total slides
const total = reveal.getTotalSlides();

// Get current slide element
const currentSlide = reveal.getCurrentSlide();

// Check if at first/last
reveal.isFirstSlide();
reveal.isLastSlide();

Toggle features:

// Toggle overview mode
reveal.toggleOverview();

Design Guidelines

Content Density

Per slide guidelines:

• Title slides: 1 title + 1-2 supporting lines
• Content slides: 1 heading + 3-7 bullet points OR 2-3 paragraphs
• Two-column: 3-5 items per column
• Image slides: 1 image + short description

The 6×6 rule: Maximum 6 bullets with 6 words each

Avoid:

• ❌ Paragraphs longer than 4 lines
• ❌ More than 7 bullet points per slide
• ❌ Tiny font sizes (< 24px)
• ❌ Wall of text
• ❌ Cramped spacing

Animation Best Practices

Use fragments for:

• ✅ Building lists progressively
• ✅ Revealing data points step-by-step
• ✅ Highlighting key information
• ✅ Controlling information flow

Use auto-animate for:

• ✅ Showing transformations
• ✅ Morphing code examples
• ✅ Animating diagrams
• ✅ Data visualizations

Avoid:

• ❌ Excessive animations (don't animate every element)
• ❌ Distracting transitions
• ❌ Animations longer than 1 second
• ❌ Too many concurrent animations

Visual Hierarchy

Create clear structure:

• Large to small: Titles (3em) → Headings (2em) → Body (1em)
• Bold to regular: Important points → Supporting details
• Color emphasis: Accent color → Primary → Body text
• Spacing: More space = more importance

Color and Accessibility

Accessibility requirements:

• Maintain 4.5:1 contrast for normal text
• Maintain 3:1 contrast for large text (18pt+)
• Don't rely solely on color to convey information
• Test with colorblind simulators

Color usage:

• Primary: Headings, links, emphasis
• Secondary: Gradients, backgrounds
• Accent: Call-to-actions, highlights

Troubleshooting

Slides Not Displaying

Issue: Blank screen or no slides appear
Solution:

• Check browser console for JavaScript errors
• Ensure <section> tags are inside .reveal .slides
• Verify CDN links are accessible (internet required)
• Check for unclosed HTML tags

Fragments Not Working

Issue: All content appears at once
Solution:

• Verify class="fragment" is set correctly
• Check that fragments: true in configuration
• Ensure no CSS overrides are hiding fragments
• Test in different browser

Speaker Notes Not Showing

Issue: Press S but no speaker window opens
Solution:

• Check popup blocker settings
• Ensure <aside class="notes"> is inside <section>
• Verify RevealNotes plugin is loaded
• Try opening in a new browser tab manually

Code Not Highlighted

Issue: Code appears as plain text
Solution:

• Add class="language-xxx" to <code> element
• Ensure RevealHighlight plugin is loaded
• Check that CDN for highlight styles is accessible
• Verify language identifier is supported

Navigation Issues

Issue: Arrow keys don't work
Solution:

• Check if presentation has focus (click on it)
• Ensure keyboard: true in configuration
• Check for JavaScript errors in console
• Test in incognito mode (disable extensions)

Vertical Slides Not Showing

Issue: Can't navigate down to nested slides
Solution:

• Ensure slides are properly nested (outer <section> contains inner ones)
• Check for proper HTML structure
• Look for down arrow indicator in controls
• Try pressing ↓ or clicking down arrow

Migration Guide (from Classic Template)

If you have existing presentations using viewer.html, here's how to migrate:

Key Differences

Feature	Classic (viewer.html)	Reveal.js (viewer-reveal.html)
Framework	Custom JavaScript	Reveal.js 5.x
Slides	JavaScript array	HTML <section> tags
Animations	CSS transitions only	Fragments, auto-animate, transitions
Speaker Notes	❌ Not available	✅ Full speaker view (press S)
Overview Mode	❌ Not available	✅ Thumbnail overview (press ESC)
Vertical Slides	❌ Not available	✅ Nested navigation
Code Highlighting	Basic	Highlight.js with line numbers
Math Equations	❌ Not available	✅ KaTeX support
Search	❌ Not available	✅ Full-text search (Ctrl+Shift+F)
Plugins	❌ None	✅ Extensive ecosystem
API Access	Limited	Full Reveal.js API

Migration Steps

1. Convert slide structure:

// OLD (viewer.html)
const SLIDES = [
    {
        layout: "title",
        content: `<h1>Title</h1>`
    }
];

// NEW (viewer-reveal.html)
<section class="slide-title">
    <h1>Title</h1>
</section>

2. Update theme configuration:

// OLD
const PRESENTATION = {
    title: "...",
    theme: { primary: "#...", ... }
};

// NEW
const PRESENTATION_CONFIG = {
    title: "...",
    theme: { primary: "#...", ... },
    revealOptions: { ... }
};

3. Add new features:

• Add class="fragment" for progressive reveals
• Wrap nested content in <section> for vertical navigation
• Add <aside class="notes"> for speaker notes
• Use Reveal.js transitions and animations
