For many projects or even Symfony components, the full functionality of the OptionsResolver is overkill. Nevertheless, the component contains code that is very useful, but not easily accessible.
I suggest to make the validate* methods in the OptionsResolver class accessible through a simple low-level API such as:
use Symfony\Component\OptionsResolver\Options;
// throws MissingOptionsException if the option(s) is (are) missing
Options::require($options, 'toTz');
// throws InvalidOptionsException if any of the options have an invalid type
Options::validateTypes($options, array(
'fromTz' => 'string',
'toTz' => 'string',
'dateFormat' => 'string',
'timeFormat' => 'string',
'calendar' => array('null', 'integer'),
));
// throws InvalidOptionsException if any of the options contain an invalid value
Options::validateValues($options, array(
'calendar' => array(
\IntlDateFormatter::GREGORIAN,
\IntlDateFormatter::TRADITIONAL,
),
));
// throws InvalidOptionsException if any of the given options is not known
$options = Options::resolve($options, array(
'fromTz' => null,
'toTz' => null,
'dateFormat' => \IntlDateFormatter::MEDIUM,
'timeFormat' => \IntlDateFormatter::SHORT,
'calendar' => \IntlDateFormatter::GREGORIAN,
));Opinions?
