## When to Use TUI Mode

### Use TUI when:
- ✅ Checking multiple workflows
- ✅ You want visual feedback
- ✅ Exploring issues interactively
- ✅ Presenting to team members
- ✅ Learning about workflow issues

### Use CLI when:
- ✅ In CI/CD pipelines
- ✅ Scripting/automation
- ✅ Quick single-file checks
- ✅ JSON output needed
- ✅ Pre-commit hooks

## Examples

### Basic Usage
```bash
# Start TUI in current directory
cd your-project
pipecheck --tui
```

### With Options
```bash
# TUI with strict mode
pipecheck --tui --strict

# TUI without Docker checks
pipecheck --tui --no-docker
```

## Tips

1. **Navigation**: Use vim-style keys (`j`/`k`) or arrow keys
2. **Quick exit**: Press `q` or `Esc` anytime
3. **Details**: Press `Enter` or `Space` to see full error details
4. **Scrolling**: Details view automatically wraps long text

| Feature | CLI | TUI |
|---------|-----|-----|
| Speed | ⚡ Instant | ⚡ Instant |
| Multiple files | List output | Interactive list |
| Error details | All at once | On-demand |

## Technical Details

- Built with [ratatui](https://github.com/ratatui-org/ratatui) - Modern Rust TUI framework
- Uses [crossterm](https://github.com/crossterm-rs/crossterm) for terminal control
- Supports all major terminals (iTerm2, Terminal.app, Windows Terminal, etc.)
- Works over SSH
- Respects terminal colors and themes

## Troubleshooting

### TUI doesn't start
```bash
# Check if terminal supports TUI
echo $TERM

# Should output something like: xterm-256color
```

### Colors look wrong
Your terminal might not support 256 colors. Try:
```bash
export TERM=xterm-256color
pipecheck --tui
```

### Keyboard shortcuts don't work
Make sure your terminal is in focus and not capturing the keys.

## Future Enhancements

Coming in future versions:
