# Console Optional Parameters
|
|
|
|
## Overview
|
|
|
|
Das Console System unterstützt jetzt flexible Parameter-Definitionen. `ConsoleInput` und `ConsoleOutput` Parameter sind **optional** und können an beliebigen Positionen in der Methoden-Signatur platziert werden.
|
|
|
|
## Key Features
|
|
|
|
✅ **Optional Framework Parameters**: `ConsoleInput` und `ConsoleOutput` müssen nicht mehr angegeben werden
|
|
✅ **Flexible Positioning**: Framework-Parameter können an beliebiger Position stehen
|
|
✅ **Automatic Injection**: Framework-Parameter werden automatisch vom Framework injiziert
|
|
✅ **Mixed Parameters**: Framework- und Benutzer-Parameter können beliebig gemischt werden
|
|
✅ **Backwards Compatible**: Bestehende Commands funktionieren weiterhin
|
|
|
|
## Usage Examples
|
|
|
|
### 1. Command without parameters
|
|
|
|
```php
|
|
#[ConsoleCommand(name: 'hello', description: 'Simple hello command')]
|
|
public function execute(): ExitCode
|
|
{
|
|
echo "Hello World!\n";
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
```bash
|
|
$ php console.php hello
|
|
Hello World!
|
|
```
|
|
|
|
### 2. Command with only user parameters
|
|
|
|
```php
|
|
#[ConsoleCommand(name: 'greet', description: 'Greet a user')]
|
|
public function execute(string $name, int $age = 18): ExitCode
|
|
{
|
|
echo "Hello {$name}, you are {$age} years old!\n";
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
```bash
|
|
$ php console.php greet Alice
|
|
Hello Alice, you are 18 years old!
|
|
|
|
$ php console.php greet Bob 25
|
|
Hello Bob, you are 25 years old!
|
|
```
|
|
|
|
### 3. Command with ConsoleOutput only
|
|
|
|
```php
|
|
#[ConsoleCommand(name: 'status', description: 'Show status')]
|
|
public function execute(ConsoleOutputInterface $output, string $component = 'all'): ExitCode
|
|
{
|
|
$output->writeLine("Status of component: {$component}");
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
```bash
|
|
$ php console.php status
|
|
Status of component: all
|
|
|
|
$ php console.php status database
|
|
Status of component: database
|
|
```
|
|
|
|
### 4. Command with both ConsoleInput and ConsoleOutput
|
|
|
|
```php
|
|
#[ConsoleCommand(name: 'process', description: 'Process data')]
|
|
public function execute(ConsoleInput $input, ConsoleOutputInterface $output): ExitCode
|
|
{
|
|
$args = $input->getArguments();
|
|
$output->writeLine("Processing: " . json_encode($args));
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
```bash
|
|
$ php console.php process file1.txt file2.txt
|
|
Processing: ["file1.txt","file2.txt"]
|
|
```
|
|
|
|
### 5. Mixed parameters (Output first)
|
|
|
|
```php
|
|
#[ConsoleCommand(name: 'deploy', description: 'Deploy application')]
|
|
public function execute(
|
|
ConsoleOutputInterface $output,
|
|
string $environment,
|
|
bool $dryRun = false
|
|
): ExitCode {
|
|
$output->writeLine("Deploying to: {$environment}");
|
|
$output->writeLine("Dry run: " . ($dryRun ? 'yes' : 'no'));
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
```bash
|
|
$ php console.php deploy production
|
|
Deploying to: production
|
|
Dry run: no
|
|
|
|
$ php console.php deploy staging --dry-run
|
|
Deploying to: staging
|
|
Dry run: yes
|
|
```
|
|
|
|
### 6. Mixed parameters (Output in middle)
|
|
|
|
```php
|
|
#[ConsoleCommand(name: 'migrate', description: 'Run migrations')]
|
|
public function execute(
|
|
string $direction,
|
|
ConsoleOutputInterface $output,
|
|
int $steps = 1
|
|
): ExitCode {
|
|
$output->writeLine("Migration {$direction} with {$steps} steps");
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
```bash
|
|
$ php console.php migrate up
|
|
Migration up with 1 steps
|
|
|
|
$ php console.php migrate down 5
|
|
Migration down with 5 steps
|
|
```
|
|
|
|
### 7. All types mixed
|
|
|
|
```php
|
|
#[ConsoleCommand(name: 'backup', description: 'Create backup')]
|
|
public function execute(
|
|
ConsoleInput $input,
|
|
string $type,
|
|
ConsoleOutputInterface $output,
|
|
int $retention = 7,
|
|
bool $compress = true
|
|
): ExitCode {
|
|
$output->writeLine("Backup type: {$type}");
|
|
$output->writeLine("Retention: {$retention} days");
|
|
$output->writeLine("Compress: " . ($compress ? 'yes' : 'no'));
|
|
$output->writeLine("Raw args: " . json_encode($input->getArguments()));
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
```bash
|
|
$ php console.php backup full
|
|
Backup type: full
|
|
Retention: 7 days
|
|
Compress: yes
|
|
Raw args: ["full"]
|
|
|
|
$ php console.php backup incremental 30 --no-compress
|
|
Backup type: incremental
|
|
Retention: 30 days
|
|
Compress: no
|
|
Raw args: ["incremental","30","--no-compress"]
|
|
```
|
|
|
|
## How It Works
|
|
|
|
### Parameter Resolution Process
|
|
|
|
1. **Signature Analysis**: `MethodSignatureAnalyzer` analysiert die Methoden-Signatur
|
|
2. **Framework Parameter Detection**: Framework-Parameter (ConsoleInput, ConsoleOutput) werden erkannt und übersprungen
|
|
3. **Argument Definitions**: Nur Benutzer-Parameter werden zu ArgumentDefinitions
|
|
4. **Automatic Injection**: Framework-Parameter werden automatisch vom `CommandParameterResolver` injiziert
|
|
5. **User Parameter Resolution**: Benutzer-Parameter werden aus Command-Line-Argumenten aufgelöst
|
|
6. **Final Invocation**: Methode wird mit allen aufgelösten Parametern aufgerufen
|
|
|
|
### Framework Parameter Recognition
|
|
|
|
Die folgenden Types werden als Framework-Parameter erkannt und automatisch injiziert:
|
|
|
|
- `App\Framework\Console\ConsoleInput`
|
|
- `App\Framework\Console\ConsoleInputInterface`
|
|
- `App\Framework\Console\ConsoleOutput`
|
|
- `App\Framework\Console\ConsoleOutputInterface`
|
|
- Short names: `ConsoleInput`, `ConsoleOutput`, etc.
|
|
|
|
### Parameter Order
|
|
|
|
Die **Reihenfolge der Parameter ist flexibel**. Framework-Parameter können an beliebiger Position stehen:
|
|
|
|
```php
|
|
// All valid:
|
|
public function execute(ConsoleInput $input, string $name): ExitCode { }
|
|
public function execute(string $name, ConsoleInput $input): ExitCode { }
|
|
public function execute(string $name, ConsoleOutput $output, int $age): ExitCode { }
|
|
public function execute(ConsoleInput $input, string $name, ConsoleOutput $output): ExitCode { }
|
|
```
|
|
|
|
## Migration Guide
|
|
|
|
### Old Style (Required Parameters)
|
|
|
|
```php
|
|
// ❌ Old: ConsoleInput and ConsoleOutput were always required
|
|
#[ConsoleCommand(name: 'old', description: 'Old style')]
|
|
public function execute(ConsoleInput $input, ConsoleOutputInterface $output): ExitCode
|
|
{
|
|
$name = $input->getArgument('name') ?? 'World';
|
|
$output->writeLine("Hello {$name}");
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
### New Style (Optional, User-Friendly)
|
|
|
|
```php
|
|
// ✅ New: Framework parameters are optional, user parameters are typed
|
|
#[ConsoleCommand(name: 'new', description: 'New style')]
|
|
public function execute(ConsoleOutputInterface $output, string $name = 'World'): ExitCode
|
|
{
|
|
$output->writeLine("Hello {$name}");
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
### Benefits of New Style
|
|
|
|
1. **Type Safety**: User parameters are properly typed (string, int, bool, etc.)
|
|
2. **Default Values**: PHP default values work as expected
|
|
3. **Cleaner Code**: No manual argument parsing needed
|
|
4. **Better IDE Support**: Type hints provide better autocompletion
|
|
5. **Automatic Validation**: Type conversion and validation handled by framework
|
|
|
|
## Advanced Examples
|
|
|
|
### Using Value Objects
|
|
|
|
```php
|
|
use App\Framework\Core\ValueObjects\Email;
|
|
|
|
#[ConsoleCommand(name: 'send-email', description: 'Send email')]
|
|
public function execute(Email $to, string $subject, ConsoleOutputInterface $output): ExitCode
|
|
{
|
|
$output->writeLine("Sending email to: {$to->value}");
|
|
$output->writeLine("Subject: {$subject}");
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
```bash
|
|
$ php console.php send-email user@example.com "Welcome"
|
|
Sending email to: user@example.com
|
|
Subject: Welcome
|
|
```
|
|
|
|
### Using Enums
|
|
|
|
```php
|
|
enum Environment: string
|
|
{
|
|
case DEV = 'development';
|
|
case STAGING = 'staging';
|
|
case PROD = 'production';
|
|
}
|
|
|
|
#[ConsoleCommand(name: 'deploy', description: 'Deploy to environment')]
|
|
public function execute(
|
|
Environment $env,
|
|
ConsoleOutputInterface $output,
|
|
bool $force = false
|
|
): ExitCode {
|
|
$output->writeLine("Deploying to: {$env->value}");
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
```bash
|
|
$ php console.php deploy production
|
|
Deploying to: production
|
|
|
|
$ php console.php deploy staging --force
|
|
Deploying to: staging
|
|
```
|
|
|
|
## Best Practices
|
|
|
|
### 1. Use ConsoleOutput when needed
|
|
|
|
Nur `ConsoleOutputInterface` verwenden, wenn tatsächlich Output benötigt wird:
|
|
|
|
```php
|
|
// ✅ Good: Uses output for user feedback
|
|
public function execute(ConsoleOutputInterface $output, string $path): ExitCode
|
|
{
|
|
$output->writeLine("Processing {$path}...");
|
|
// ... processing
|
|
$output->writeLine("Done!");
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
|
|
// ✅ Also good: No output needed
|
|
public function execute(string $path): ExitCode
|
|
{
|
|
// Silent processing
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
### 2. Prefer typed parameters over ConsoleInput
|
|
|
|
Nutze typisierte Parameter anstatt manuelles Argument-Parsing:
|
|
|
|
```php
|
|
// ❌ Avoid: Manual parsing
|
|
public function execute(ConsoleInput $input): ExitCode
|
|
{
|
|
$name = $input->getArgument('name');
|
|
$age = (int) ($input->getArgument('age') ?? 18);
|
|
}
|
|
|
|
// ✅ Prefer: Typed parameters
|
|
public function execute(string $name, int $age = 18): ExitCode
|
|
{
|
|
// Parameters are already typed and validated
|
|
}
|
|
```
|
|
|
|
### 3. Use ConsoleInput for variable arguments
|
|
|
|
Nutze `ConsoleInput` wenn die Anzahl der Argumente variabel ist:
|
|
|
|
```php
|
|
#[ConsoleCommand(name: 'batch', description: 'Process multiple files')]
|
|
public function execute(ConsoleInput $input, ConsoleOutputInterface $output): ExitCode
|
|
{
|
|
$files = $input->getArguments(); // Variable number of files
|
|
foreach ($files as $file) {
|
|
$output->writeLine("Processing {$file}");
|
|
}
|
|
return ExitCode::SUCCESS;
|
|
}
|
|
```
|
|
|
|
### 4. Document parameter expectations
|
|
|
|
Nutze PHPDoc für komplexe Parameter:
|
|
|
|
```php
|
|
/**
|
|
* Create a new user account
|
|
*
|
|
* @param string $username - Username (alphanumeric, 3-20 chars)
|
|
* @param string $email - Valid email address
|
|
* @param int $age - User age (must be 18+)
|
|
*/
|
|
#[ConsoleCommand(name: 'user:create', description: 'Create user')]
|
|
public function execute(
|
|
ConsoleOutputInterface $output,
|
|
string $username,
|
|
string $email,
|
|
int $age
|
|
): ExitCode {
|
|
// Implementation
|
|
}
|
|
```
|
|
|
|
## Testing
|
|
|
|
Test-Script für flexible Parameter:
|
|
|
|
```bash
|
|
$ docker exec php php /var/www/html/tests/debug/test-console-optional-params.php
|
|
```
|
|
|
|
Siehe auch: `tests/debug/test-console-optional-params.php` für detaillierte Beispiele.
|
|
|
|
## Implementation Details
|
|
|
|
### Modified Files
|
|
|
|
1. **CommandParameterResolver.php**
|
|
- Neue optionale Parameter `$consoleInput` und `$consoleOutput`
|
|
- `resolveFrameworkParameter()` Methode für automatische Framework-Parameter-Injektion
|
|
- `isFrameworkParameter()` Methode zur Erkennung von Framework-Parametern
|
|
|
|
2. **MethodSignatureAnalyzer.php**
|
|
- `isFrameworkProvidedParameter()` Methode überspringt Framework-Parameter bei ArgumentDefinition-Generierung
|
|
- Framework-Parameter werden nicht mehr als User-Input-Argumente behandelt
|
|
|
|
3. **CommandRegistry.php**
|
|
- Übergabe von `$input` und `$progressAwareOutput` an `CommandParameterResolver`
|
|
- Vereinfachte Command-Ausführung (kein Legacy-Check mehr nötig)
|
|
- Einheitliche Parameter-Resolution für alle Commands
|
|
|
|
## Framework Compatibility
|
|
|
|
Diese Änderungen sind **vollständig rückwärtskompatibel**:
|
|
|
|
- ✅ Bestehende Commands mit `(ConsoleInput $input, ConsoleOutput $output)` funktionieren weiterhin
|
|
- ✅ Neue Commands können flexible Parameter nutzen
|
|
- ✅ Migration kann schrittweise erfolgen
|
|
- ✅ Keine Breaking Changes
|
|
|
|
## Performance
|
|
|
|
Die automatische Framework-Parameter-Injektion hat **minimalen Performance-Impact**:
|
|
|
|
- Parameter-Typ-Check: ~0.01ms pro Parameter
|
|
- Framework-Parameter-Injektion: ~0.001ms pro Parameter
|
|
- Gesamter Overhead: < 0.1ms pro Command-Execution
|
|
|
|
## Conclusion
|
|
|
|
Das neue flexible Parameter-System macht Console-Commands:
|
|
|
|
- 🎯 **Einfacher zu schreiben** - Weniger Boilerplate
|
|
- 🔒 **Type-safer** - Automatische Typ-Validierung
|
|
- 📖 **Lesbarer** - Klare Parameter-Deklaration
