[NTG-context] Hooking stoptext

8 Oct 2013

      Hello,

I'm trying to hook commands.stoptext()...

Here's a minimal example: why only the first image appears?

----
\startluacode
   local cmd_p
   local tab = {}

   f = function(a)
     if not cmd_p then
       cmd_p = commands.stoptext

       commands.stoptext = function(...)
         context("Hook")

         for _, v in ipairs(tab) do
           context.startTEXpage()
             context.externalfigure{v}
           context.stopTEXpage()
         end

         cmd_p(...)
       end
     end

     table.insert(tab, a)
   end
\stopluacode

\starttext
   A
   \ctxlua{f("cow")}
   \ctxlua{f("hacker")}
\stoptext
----

When I modify the code:

----
...
         for _, v in ipairs(tab) do
           --context.startTEXpage()
             context.externalfigure{v}
           --context.stopTEXpage()
         end
...
----

all figures are shown OK.

Where's the problem?

TIA.

Best regards,

Lukas
