Changing the Default Command
Changing the Default Command¶
The Console component will always run the ListCommand when no command name is
passed. In order to change the default command you just need to pass the command
name to the setDefaultCommand() method:
namespace Acme\Console\Command;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
class HelloWorldCommand extends Command
{
protected function configure()
{
$this->setName('hello:world')
->setDescription('Outputs \'Hello World\'');
}
protected function execute(InputInterface $input, OutputInterface $output)
{
$output->writeln('Hello World');
}
}
Executing the application and changing the default command:
// application.php
use Acme\Console\Command\HelloWorldCommand;
use Symfony\Component\Console\Application;
$command = new HelloWorldCommand();
$application = new Application();
$application->add($command);
$application->setDefaultCommand($command->getName());
$application->run();
Test the new default console command by running the following:
1 | $ php application.php
|
This will print the following to the command line:
1 | Hello World
|
Caution
This feature has a limitation: you cannot pass any argument or option to the default command because they are ignored.
