hello,
i try to understand the difference of everybeforeoutput and everafteroutput to
inject some pages. it seems as there is no difference.
\the\everybeforeoutput is placed after the output of the page:
\newtoks\Before
\appendtoks
\the\Before
\global\Before\emptytoks
\to\everybeforeoutput
\newtoks\After
\appendtoks
\the\After
\global\After\emptytoks
\to\everyafteroutput
\starttext
\input{knuth}\par
\appendtoks{before}\to\Before
\appendtoks{after}\to\After
\stoptext
this code in page-otr.mkvi seems to put it before the content:
\def\page_otf_set_engine_output_routine#content%
{\global\output
{\inotrtrue
\the\everybeforeoutput
#content\relax
\the\everyafteroutput}}
can this be fixed?
there is nothing wrong .. you feed something in the output routine there
you can try to use one of the other \before\after ones but be aware of
possible interferences with tex's state, hold content etc ...
\startpostponing ... might do what you want
