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?
An alternative is to use (untested)

\appendtoks ... \to \everystoptext
