The method addDelegate() does not exist on Railt\Parser\GrammarInterface. Did you maybe mean delegate()?

It seems like you code against a concrete implementation and not the interface Railt\Parser\Ast\NodeInterface as the method first() does only exist in the following implementations of said interface: Railt\Compiler\Grammar\Delegate\IncludeDelegate, Railt\Compiler\Grammar\Delegate\RuleDelegate, Railt\Compiler\Grammar\Delegate\TokenDelegate, Railt\Parser\Ast\Rule.

            ->first('RuleName')
            ->first('T_NAME')
            ->getValue();
    }

    /**
     * @return bool
     */
    public function isKept(): bool
    {
        return (bool)$this->first('ShouldKeep');
    }

    /**
     * @return null|string
     */
    public function getDelegate(): ?string
    {
        $delegate = $this->first('RuleDelegate');

        if ($delegate instanceof RuleInterface) {
            return $delegate->first('T_NAME')->getValue();

The method getValue() does not exist on Railt\Parser\Ast\NodeInterface. Did you maybe mean getValues()?

        }

        return null;
    }
