Console Component

Console eases the creation of beautiful and testable command line interfaces.

The Application object manages the CLI application:

use Symfony\Component\Console\Application;

$console = new Application();

The run() method parses the arguments and options passed on the command line and executes the right command.

Registering a new command can easily be done via the register() method, which returns a Command instance:

use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Output\OutputInterface;

        new InputArgument('dir', InputArgument::REQUIRED, 'Directory name'),
    ->setDescription('Displays the files in the given directory')
    ->setCode(function (InputInterface $input, OutputInterface $output) {
        $dir = $input->getArgument('dir');

        $output->writeln(sprintf('Dir listing for <info>%s</info>', $dir));

You can also register new commands via classes.

The component provides a lot of features like output coloring, input and output abstractions (so that you can easily unit-test your commands), validation, automatic help messages, ...
