The Pimple edition

As explained in the dependency injection documentation, Silly can work with any dependency injection container.

However in order to provide an easy way to get started we provide a "Pimple edition" that is already configured with the Pimple container.

Pimple provides less features than the PHP-DI edition (for example no autowiring) but might interest those already familiar with it, e.g. Silex users.

Installation

$ composer require mnapoli/silly-pimple

Usage

You can store command callables in the container:

class MyCommand
{
    public function execute($name, OutputInterface $output)
    {
        if ($name) {
            $text = 'Hello, '.$name;
        } else {
            $text = 'Hello';
        }

        $output->writeln($text);
    }
}

$app = new Silly\Edition\Pimple\Application();
$pimple = $app->getContainer();

$pimple['command.greet'] = function () {
    return new MyCommand();
};

$app->command('greet [name]', 'command.greet');

$app->run();

Dependency injection in parameters

You can also use dependency injection in parameters:

use Psr\Logger\LoggerInterface;

// ...

$pimple = $app->getContainer();

$pimple['dbHost'] = 'localhost';
$pimple[LoggerInterface::class] = function () {
    new Monolog\Logger(/* ... */);
};

$app->command('greet [name]', function ($name, $dbHost, LoggerInterface $logger) {
    // ...
});

$app->run();

Dependency injection in parameters follows the precedence rules explained in the dependency injection documentation:

  • command parameters are matched in priority using the parameter names ($name)
  • then container entries are matched using the callable type-hint (Psr\Logger\LoggerInterface)
  • finally container entries are matched using the parameter names ($dbHost)
