ConsoleServiceProvider

Provides a Symfony\Component\Console based console for Silex.

Install

Add knplabs/console-service-provider to your composer.json and register the service:

<?php

use Knp\Provider\ConsoleServiceProvider;

$app->register(new ConsoleServiceProvider(), array(
    'console.name'              => 'MyApplication',
    'console.version'           => '1.0.0',
    'console.project_directory' => __DIR__.'/..'
));

?>

You can now copy the console executable in whatever place you see fit, and tweak it to your needs. You will need a way to fetch your silex application, the most common way is to return it from your bootstrap:

<?php

$app = new Silex\Application();

// your beautiful silex bootstrap

return $app;

?>

For the rest of this document, we will assume you do have an app directory, so the console executable will be located at app/console.

Usage

Use the console just like any Symfony\Component based console:

$ app/console my:command

Write commands

Your commands should extend Knp\Command\Command to have access to the 2 useful following commands:

• getSilexApplication, which returns the silex application
• getProjectDirectory, which returns your project's root directory (as configured earlier)

I know, it's a lot to learn, but it's worth the pain.

Register commands

There are two ways of registering commands to the console application.

Directly access the console application from the console executable

Open up app/console, and stuff your commands directly into the console application:

#!/usr/bin/env php
<?php

set_time_limit(0);

$app = require_once __DIR__.'/bootstrap.php';

use My\Command\MyCommand;

$application = $app['console'];
$application->add(new MyCommand());
$application->run();

?>

Use the Event Dispatcher

This way is intended for use by provider developers and exposes an unobstrusive way to register commands in 3 simple steps:

1. Register a listener to the ConsoleEvents::INIT event
2. ???
3. PROFIT!

Example:

<?php

use My\Command\MyCommand;
use Knp\Console\ConsoleEvents;
use Knp\Console\ConsoleEvent;

$app['dispatcher']->addListener(ConsoleEvents::INIT, function(ConsoleEvent $event) {
    $app = $event->getApplication();
    $app->add(new MyCommand());            
});

?>
