Building a single Command Application
When building a command line tool, you may not need to provide several commands. In such a case, having to pass the command name each time is tedious. Fortunately, it is possible to remove this need by declaring a single command application:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
#!/usr/bin/env php <?php require __DIR__.'/vendor/autoload.php'; use Symfony\Component\Console\Attribute\Argument; use Symfony\Component\Console\Attribute\Option; use Symfony\Component\Console\Output\OutputInterface; use Symfony\Component\Console\SingleCommandApplication; (new SingleCommandApplication()) ->setName('My Super Command') // Optional ->setVersion('1.0.0') // Optional ->setCode(function (OutputInterface $output, #[Argument] string $foo = 'The directory', #[Option] string $bar = ''): int { // output arguments and options return 0; }) ->run();You can still register a command as usual:
1 2 3 4 5 6 7 8 9 10 11 12 13 14
#!/usr/bin/env php <?php require __DIR__.'/vendor/autoload.php'; use Acme\Command\DefaultCommand; use Symfony\Component\Console\Application; $application = new Application('echo', '1.0.0'); $command = new DefaultCommand(); $application->add($command); $application->setDefaultCommand($command->getName(), true); $application->run();The setDefaultCommand() method accepts a boolean as second parameter. If true, the command echo will then always be used, without having to pass its name.
