Dear list,
I need to get the number of pages from an external PDF file that I also
define with an \env.
I think I could get something like this.:
\def\Myfilename{\env{filename}}
doc = epdf.open(arg[\MyFilename])
total_pages_ = doc:getNumPages()
\def\Mypages{total_pages}
But mixing both lua and ConTeXt commands the wrong way won’t work.
Sorry, but this is all Greek to me. Although I see how it could be done,
I cannot write the code for this.
Which is the right way to get the code above working?
Many thanks for your help,
Pablo

From my old cut-n-paste module (to format two column pdfs into one column
so that they are easier to read on an eink reader)
\useexternalfigure[cnp:name][\cut!n!paste!parameter\c!name]% Is this really needed?
\getfiguredimensions[cnp:name]%
\edef\cut!n!paste!NOfpages {\noffigurepages}%

Many thanks for your reply, Hans.
It works like charm.
Now I can generate my booklets fully automatic (for the people :-)).
Many thanks again for your help,
Pablo
