I wish this help you You are correct, Volt does not support bitwise operators. One of workarounds is to create your functions when declaring voltService:
code :
$di->setShared('view', function() {

    $view = new \Phalcon\Mvc\View();

    $view->registerEngines(array(
        '.volt' => 'voltService'
    ));

    return $view;
});

$di->set('voltService', function ($view, $di) {
    // ...

    $volt = new Phalcon\Mvc\View\Engine\Volt($view, $di);
    // ...

    $compiler = $volt->getCompiler();

    $compiler->addFunction('bit_and', function($resolvedArgs, $exprArgs) use ($compiler) {

        return sprintf(
            '(%s & %s)',
            $compiler->expression($exprArgs[0]['expr']),
            $compiler->expression($exprArgs[1]['expr'])
        );

    });

    return $volt;
});
{% if bit_and(2, keyword.getFlags()) %}
    checked="checked"
{% endif %}

wish helps you That comes from the fact that the application cannot find the file main.html in the actual path. If you add the full path it works, however it is inconvenient to do so.
Something like this will work
code :
{% extends  "../views/layouts/main.html" %}
{% extends  "../app/views/layouts/main.html" %}
How can I set own Tag class in Volt (Phalcon)

How can I set own Tag class in Volt (Phalcon)

I wish did fix the issue. First of all: don't use tag as your service name because it's already used by Phalcon's Tag object. Secondly you can use static methods from class.
Below is a working example for myTag using config from my app with changed names for your example.
code :
$di->set(
'view',
function () use ($config) {
    $view = new View();
    $view->setViewsDir($config->application->viewsDir);
    $view->registerEngines(
        array(
            '.volt' => function ($view, $di) use ($config) {

                $volt = new VoltEngine($view, $di);
                $volt->setOptions(
                    array(
                        'compiledPath' => $config->application->cacheDir,
                        'compiledSeparator' => '_',
                        'compileAlways' => false
                    )
                );
                $compiler = $volt->getCompiler();

                // add a function
                $compiler->addFunction(
                    'myTag',
                    function ($resolvedArgs, $exprArgs) {
                        return 'MyTags::mytag(' . $resolvedArgs . ')';
                    }
                );

                // or filter
                $compiler->addFilter(
                    'myFilter',
                    function ($resolvedArgs, $exprArgs) {
                        return 'MyTags::mytag(' . $resolvedArgs . ')';
                    }
                );

                return $volt;
            }
        )
        );

        return $view;
    },
    true
);
class MyTags extends \Phalcon\Tag
{
    /**
     * Look no static keyword here
     */
    public function mytag($params)
    {
       <...>
    }
}
$di->set('mahTag', function() {
    return new MyTags();
};
{{ mahTag.mytag() }}
