Single Command Applications

[tqmz]

I'd find it generally useful to let Silly support Single Command Applications out of the box.

A simple way of providing this might be offering a Silly\SingleCommandApplication.
Respectively, Silly\Edition\PhpDi\SingleCommandApplication for PHP-DI.

What do you think?

Why not, but how would the single command be defined? It sounds a bit vague for now.

Please check #31 for an approach.

Actually Symfony already provides support for that. I've needed that so I had a look, it's as simple as doing this:

$app->command('run', /* ... */);
$app->setDefaultCommand('run');

I've added it to the documentation.

If you want to use ->setDefaultCommand() and pass parameters then you need to pass the 2nd parameter to setDefaultCommand:

use Symfony\Component\Console\Output\OutputInterface;

$app = new Silly\Application();

$app->command( 'greet [name] [--yell]', function ( $name, $yell, OutputInterface $output ) {

	if ( ! $yell ) {
		return false;
	}

		$output->writeln( $name );
} );

$app->setDefaultCommand( 'greet', true ); // 2nd Parameter: bool $isSingleCommand = false

$app->run();

But then running the sub-command greet requires --:

...so you can't really have sub-commands (and them operate normally) when you make a single command (default) re-direct to a sub-command.
