Extract Static Calls from Latte Templates to FilterProvider

Do you have a static call in your template? It's a hidden filter. Let's decouple it so we can use DI and services as in the rest of project:

vendor/bin/template-checker extract-latte-static-call-to-filter templates

But that's just a dry run... how to apply changes?

vendor/bin/template-checker extract-latte-static-call-to-filter templates --fix

What happens? The static call will be replaced by a Latte filter:

 # any latte file
-{\App\SomeClass::someStaticMethod($value)}
+{$value|someStaticMethod}

The filter will be provided

use App\Contract\Latte\FilterProviderInterface;
use App\SomeClass;

final class SomeMethodFilterProvider implements FilterProviderInterface
{
    public const FILTER_NAME = 'someMethod';

    public function __invoke(string $name): int
    {
        return SomeClass::someStaticMethod($name);
    }

    public function getName(): string
    {
        return self::FILTER_NAME;
    }
}

The file will be generated into /generated directory. Just rename namespaces and copy it to your workflow.
