🚀 Migration Strategy

Backward Compatibility

• ✅ Direktes Output-Schreiben weiterhin möglich

Gradual Adoption

1. Phase 1: ConsoleResponse verfügbar, optional nutzbar
2. Phase 2: Template-System verfügbar, Commands können migrieren
3. Phase 3: Layout-System verfügbar für komplexe Use Cases

Migration Patterns

// Old: ExitCode + Direct Output
#[ConsoleCommand(name: 'old')]
public function old(ConsoleInput $input, ConsoleOutput $output): ExitCode
{
    $output->writeLine("Done");
    return ExitCode::SUCCESS;
}

// New: ConsoleResponse
#[ConsoleCommand(name: 'new')]
public function new(ConsoleInput $input): ConsoleResponse
{
    return ConsoleTextResponse::success("Done");
}

// Transition: Both
#[ConsoleCommand(name: 'transition')]
public function transition(ConsoleInput $input, ConsoleOutput $output): ConsoleResponse
{
    $output->writeLine("Processing..."); // Progress output
    return ConsoleTextResponse::success("Done"); // Final result
}

📝 Notes & Decisions

Design Decisions

1. String-based Templates (nicht DOM) - Einfacher für Console-Output
2. Method-based Commands - Kompatibel mit #[ConsoleCommand] Attribute
3. Backward Compatible - Beide Return-Typen (ExitCode | ConsoleResponse)
4. Adapter Pattern - Wrapper für bestehende mutable Components
5. Composition - Layout aus Components komponieren, nicht erben

Open Questions

• Template-Caching Strategy?
• Performance-Optimierung für große Outputs?
• ANSI-Code-Handling in Templates?
• Interactive Components in Templates?

Future Enhancements

• Progress Bars in Templates
• Animated Spinners in Templates
• Color Themes für Templates
