From the change log on # 3.0.0-BETA1 (2019-11-11)

  • removed the "base_template_class" option on Twig\Environment

I have a custom Template class extend from Twig\Template which override the display() and render() function

public function display(array $context, array $blocks = null)
    {
        $env = $this->env;
        $env->addTemplateStack($this->getTemplateName());

        if (is_array($blocks))
        {
           
            $env->current_inheritance_level++;
            $this->inheritance_level = $env->current_inheritance_level;
            $env->active_inheritance_level = $env->current_inheritance_level;
            parent::display($context, $blocks);
        }
        else {
            // Call to the deepest template or include
            parent::display($context, []);
        }
    }

public function render(array $context)
{
    $env = $this->env;

    $this->inheritance_level = 0;
    $env->active_inheritance_level = 0;
    $env->current_inheritance_level = 0;

    return parent::render($context);
}

But with Twig V3 base_template_class option was removed So I have to use the original display & render function instead. What is the alternative to having these kinds of data on V3

    I've haven't found an answer to this question myself, but it seems you need to use some hooks like `doEnterNode` / `doLeaveNode` as discussed [here](https://stackoverflow.com/questions/58266357/twig-deprecated-base-template-class-how-to-override-or-hook-to-render-with-n). This [question](https://stackoverflow.com/questions/69881387/adding-debug-traces-to-symfony-3-4-twig-templates-during-after-render) has a code example with the nodes – DarkBee Jun 08 '22 at 05:47
