How to get current template name in a TWIG function

Question

let\'s say I have created a custom twig function: templateName.

$twig = new Twig_Environment($loader);
$twig->addFunction(\'templateName\', new Twig_Func

The solution proposed by Mario A did not work for me, but using debug_backtrace() is a great idea and a little modification made it work with a recent Twig version:

    private function getTwigTemplateName()
{
    foreach (debug_backtrace() as $trace) {
        if (isset($trace['object']) 
             && (strpos($trace['class'], 'TwigTemplate') !== false) 
             && 'Twig_Template' !== get_class($trace['object'])
        ) {
            return $trace['object']->getTemplateName() . "({$trace['line']})";
        }
    }
    return '';
}
