> I didn’t know how to get an array (or indexed table or whatever you call it) in ConTeXt/Tex. My problem is now with context(context.noffigurepages). It doesn’t produce an integer so n is being compared to nil. Am I calling it wrong? All I want to do is call \noffigurepages from the lua side. Is there something I am missing?
For a more low-level interface to finding the number of pages, see:
