Sorry for the noise, I solved it with Lua. The cld manual even 
contains a combinations example.


The Lua method is also simpler than a TeX based alternative.

\starttext

\startcollecting
%
\startcollect
\startcombination[3*1]
\stopcollect
%
\dorecurse{3}
  {\startcollect
   {\externalfigure[dummy]}{}
   \stopcollect}
%
\startcollect
\stopcombination
\stopcollect
%
\stopcollecting

\stoptext

[NTG-context] dorecurse within combination

2022-07-07 Thread Henning Hraban Ramm via ntg-context 

Hi, I’d like to place pages from a multipage PDF in a combination:

\startcombination[3*1]
\dorecurse{3}{%
  {\externalfigure[multipage][width=\textwidth/3,page=\recurselevel]}{}
}
\stopcombination

That doesn’t work, because ConTeXt expects a { after \startcombination. 
(“A left brace was mandatory here, so I've put one in.”)

I guess I need some expansion, but \expanded doesn’t help.

How can I do this?

Hraban
