在twig扩展中获取模板名称

Question

Is it possible to get the name of the template that is calling a method in a twig extension?

Example:

private $templateInUse;

public function __construct(){
    $templateInUse = $this->someMagicalFunction();
}

/**
 * {@inheritdoc}
 */
public function getName() {
    return 'twig_extension';
}

public function getTokenParsers()
{
    return array(new TokenParser($this->templateInUse));
}

It would up eventually have an output of some:file:path.html.twig

Answer 1

As it turns out, you can get the template name from the stream itself.

class FooTokenParser extends Twig_TokenParser
{

    public function parse(Twig_Token $token)
    {

        $this->parser->getStream()->getFilename();
    }
}
