Easily Validate Questions in Symfony/Console

ValidableQuestion

Easily validate a Symfony/Console Question., _(*1)

Usage

$question = new ValidableQuestion('Who are you?', ['required']);
$question = new ValidableQuestion('How old are you?', ['numeric'], 25);
$question = new ValidableQuestion('Enter your e-mail', ['required', 'email']);

$helper->ask($input, $output, $question);

Why?

Validating a Question in Symfony/Console involves calling setValidator on each Question and passing the function that will actually validate it as an argument, which is awesome when you need to do a somehow complex validation, but quite annoying when you simply want to check if the value is not null, or a number, or an e-mail, etc. ValidableQuestion extends Console's Question, but validates the answer against any rules specified in the background, leaving you with a nice and readable one liner., _(*2)
