Is there a way of displaying a list of the variable names available in a particular page. I have come from Smarty where the debug option lists them really simply which makes it clear whether you have mistyped a variable or whether it is just not available to the page.

I can see this should be possible by using the twig dump function. But I cant get it to work despite setting the debug value in the twig environemnt. Has anyone else got the twig dump command to work?

This would be very helpful.

Also, I see there is a "meta" tab, and I know there's an issue been raised on GitHub #45 for this to be accessed, so hopefully that will happen soon :)
