## Quick Start

### Generate All Demos

Use the provided script:

```bash
./examples/vhs/generate_all.sh
```

This will generate all three GIF files automatically.

### Generate Individual Demos

From the project root:

```bash
# Quick demo
vhs examples/vhs/quickstart.tape

# Example demo
vhs examples/vhs/main_menu.tape

# Full demo
vhs examples/vhs/full_demo.tape
```

### View Generated GIFs

```bash
# macOS
open examples/vhs/quickstart.gif

# Linux
xdg-open examples/vhs/quickstart.gif

# Or use your preferred image viewer
```

## Customizing Tapes

### Basic Structure

A VHS tape file consists of commands that control the recording:

```tape
# Settings
Output output.gif
Set Shell "bash"
Set FontSize 14
Set Width 1200
Set Height 800

# Actions
Type "droidtui"
Enter
Sleep 2s
Type "q"
```

### Common Commands

| Command | Description | Example |
|---------|-------------|---------|
| `Output` | Set output filename | `Output demo.gif` |
| `Set` | Configure settings | `Set FontSize 16` |
| `Type` | Type text | `Type "hello"` |
| `Enter` | Press Enter key | `Enter` |
| `Sleep` | Wait duration | `Sleep 1s` |
| `Up/Down` | Arrow keys | `Down 3` |
| `Space` | Press spacebar | `Space` |
| `Backspace` | Press backspace | `Backspace` |
| `Ctrl+C` | Control key combo | `Ctrl+C` |

### Settings

Common VHS settings used in our tapes:

```tape
Set Shell "bash"          # Shell to use
Set FontSize 14           # Terminal font size
Set Width 1200            # Terminal width in pixels
Set Height 800            # Terminal height in pixels
Set Padding 20            # Padding around terminal
Set Theme "Dracula"       # Color theme
Set TypingSpeed 50ms      # Speed of typing
Set PlaybackSpeed 1.0     # Playback speed multiplier
```

### Available Themes

VHS supports many themes:
- `Dracula` (default in our tapes)
- `Nord`
- `Monokai`
- `Solarized Dark`
- `Solarized Light`
- `Gruvbox Dark`
- And many more...

## Creating New Tapes

### Template

```tape
# Output settings
Output examples/vhs/my_demo.gif
Set Shell "bash"
Set FontSize 14
Set Width 1200
Set Height 800
Set Padding 20
Set Theme "Dracula"

# Your demo script
Type "droidtui"
Enter
Sleep 2s

# ... your actions ...

Type "q"
Sleep 1s
```

### Best Practices

1. **Keep it focused** - Each tape should demonstrate one concept
2. **Use appropriate timing** - 500ms-1s for quick actions, 1.5-2s for viewing
3. **Add context** - Use `Type "# Comment"` to explain what's happening
4. **Test multiple times** - Run the tape several times to ensure consistency
5. **Optimize file size** - Shorter recordings = smaller GIFs
6. **Clear state** - Start with `clear` or fresh terminal state
7. **End cleanly** - Always quit the application properly

### Tips for Recording droidtui

```tape
# Wait for startup animation (important!)
Sleep 3s

# Press any key to continue past startup
Space
Sleep 1s

# Use navigation keys
Type "j"    # Move down
Type "k"    # Move up
Enter       # Select/Enter submenu
Backspace   # Go back to main menu
Type "q"    # Quit

# Add pauses to show content
Sleep 1.5s  # Let viewers read
```

## Troubleshooting

### VHS Command Not Found

Ensure VHS is in your PATH:
```bash
which vhs
# If not found, reinstall or check installation
```

### ttyd Not Found

Install ttyd (required by VHS):
```bash
# macOS
brew install ttyd

# Linux
sudo apt install ttyd  # Ubuntu/Debian
```

### GIF Not Generated

Check for errors in the VHS output:
```bash
vhs examples/vhs/quickstart.tape --verbose
```

### Recording Too Long

- Reduce sleep times
- Remove unnecessary navigation
- Focus on key features only

### Application Not Found

Make sure droidtui is built and in PATH:
```bash
cargo build --release
# Or install it
cargo install --path .
```

For the example demos:
```bash
# Make sure you can run the example
cargo run --example main_menu
```

## Output Files

Generated files (`.gif`, `.mp4`, `.webm`) are ignored by git (see `.gitignore`).

To share demos:
1. Generate the GIFs
2. Upload to GitHub releases or issues
3. Or host on image sharing services
