it is possible to remove this need by declaring a single command application::
#!/usr/bin/env php
- setName('My Super Command') // Optional
+ ->setName('File Counter') // Optional
->setVersion('1.0.0') // Optional
- ->addArgument('foo', InputArgument::OPTIONAL, 'The directory')
- ->addOption('bar', null, InputOption::VALUE_REQUIRED)
+ ->addArgument('dir', InputArgument::OPTIONAL, 'The directory', default: '.')
+ ->addOption('all', 'a', InputOption::VALUE_NONE, 'count all files')
->setCode(function (InputInterface $input, OutputInterface $output): int {
- // output arguments and options
+ $dir = realpath($input->getArgument('dir'));
+ $all = $input->getOption('all');
+ $finder = (new Symfony\Component\Finder\Finder())
+ ->in($dir)
+ ->files()
+ ->ignoreVCSIgnored(!$all)
+ ;
+ $count = iterator_count($finder);
+ $output->writeln( "$dir has $count " .
+ ($all ? "files" : "files in source control"));
+ return SingleCommandApplication::SUCCESS;
})
->run();
+Now run it with
+
+ php bin/file-counter.php
+
+ php bin/file-counter.php --all
+
You can still register a command as usual::
#!/usr/bin/env php
