How do you iterate over the dictionary of a stream?


I know less than nothing about Lua, but the following at least compiles.  It may provide a clue.

% !TeX Program=LuaTeX


\directlua

 {%

   local doc = pdfe.open ('Hoi-An TA menu.pdf')

   local stream = doc.Pages [1].Contents


   % this works

   print (stream.Length)


   % this doesn't

   for k, v in pairs (pdfe.dictionarytotable (doc.Pages [1])) do

   print (k, v)

   end

  }


\bye
