feature #34819 [Console] Add SingleCommandApplication to ease creation of Single Command Application (lyrixx)
This PR was merged into the 5.1-dev branch. Discussion ---------- [Console] Add SingleCommandApplication to ease creation of Single Command Application | Q | A | ------------- | --- | Branch? | master | Bug fix? | no | New feature? | yes | Deprecations? | no | Tickets | Fix #34293 | License | MIT | Doc PR | --- ```php <?php require __DIR__.'/vendor/autoload.php'; use Symfony\Component\Console\Input\InputArgument; use Symfony\Component\Console\Input\InputInterface; use Symfony\Component\Console\Output\OutputInterface; use Symfony\Component\Console\SingleCommandApplication; (new SingleCommandApplication()) ->setName('My Super Command') // Optional ->setVersion('1.0.0') // Optional ->setProcessTitle('my_proc_title') // Optional ->addArgument('who', InputArgument::OPTIONAL, 'Who', 'World') // Optional ->setCode(function(InputInterface $input, OutputInterface $output) { $output->writeln(sprintf('Hello %s!', $input->getArgument('who'))); }) ->run() ; ``` --- Note: I tried this too, and it works as expected: ```php class MyCommand extends SingleCommandApplication { public function execute(InputInterface $input, OutputInterface $output) { $output->writeln('hello'); return 0; } } new MyCommand(); ``` Commits ------- 4af513d [Console] Add SingleCommandApplication to ease creation of Single Command Application
