How to var_dump variables in twig templates?

Question

View layer pattern where you only present what you have been given is fine and all, but how do you know what is available? Is there a \"list all defined variables\" function

Answer 1

You can edit

/vendor/twig/twig/lib/Twig/Extension/Debug.php

and change the var_dump() functions to \Doctrine\Common\Util\Debug::dump()
