Creating a command

Creating your own custom commands is easy. Commands are defined in classes extending Symfony\Component\Console\Command\Command within your bundle. Below is a worked example to create a basic command to ouput some text to the terminal.

namespace Custom\MyBundle\Command;

use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

class MyCustomCommand extends Command
{
    protected function configure()
    {
        $this->setName('my-custom-command')
            ->setDescription('A custom command');
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $output->write('This is my custom command.');
    }
}

The commands must be registered as services and tagged with the console.command tag:

MyBundle\Command\MyCustomCommand:
    tags:
        - { name: console.command }

If you didn't do so already, you must ensure that your Bundle is registered with the Jadu application:

<bundles xmlns:config="http://www.jadu.co.uk/schema/config">
    <core config:type="array">
        <item key="my-bundle">Custom\MyBundle</item>
    </core>

Make sure you clear the cache to update the site's configuration. You should now see your command listed within php cli.php list.

You can now run the command via cli.php:

$ php cli.php my-custom-command
This is my custom command.
