How to display the pages of a particular section in another PDF?
I can use this code to display page 5 from a PDF:\externalfigure[filename.pdf][page=5]I am making a teacher's guide for a workbook (workbook.pdf). I need to be able to display on the page all pages of a particular section. The teacher's guide uses the same section titles as the workbook, e.g.: 17-A: Title 17-B: Title In other words, there is 1:1 pairing of section titles in the teacher's guide and the workbook. Is there any way to tell ConTeXt to display all of the pages for a particular section? \externalfigure[filename.pdf][section=17A] --Joel
Don’t know about ConTeXt. But maybe you might want to have a look at pdftk. You could try to produce per-section pdfs and include those.
Best,
Denis

Use a loop in Lua or TeX: https://wiki.contextgarden.net/System_Macros/Loops_and_Recursion \dostepwiserecurse {5} {17} {1} {\externalfigure[filename.pdf][page=\recurselevel]} or \startluacode for s=5, 17 do context.externalfigure({"filename.pdf"},{page=s}) end \stopluacode (untested) Hraban

Hi Hans, it would be great to have something like: \loadsection [1] [2] [3] 1 FILE 2 REFERENCE 3 inherits from \setupexternalfigure Just in case it may be relevant to the discussion. Many thanks for your help, Pablo

Hi Hans,
it would be great to have something like:
\loadsection [1] [2] [3]
1 FILE 2 REFERENCE 3 inherits from \setupexternalfigure
Just in case it may be relevant to the discussion.

That would be great for me.
keep in mind that it is also a biut fragile as one never know where the last one ends
I wondered whether \doifreference{\lastsectionpage[file][reference]} would make sense here, but this would probably be a way of unnecesarily complicating things... Many thanks for your help, Pablo

Thanks so much! It took some work for me to figure out how to make it work, but it now works great!

Many thanks for the implementation, Hans. https://wiki.contextgarden.net/Including_pages_from_PDF_documents contains the new information (please, Joel, could you check whether the explanation is clear?). But I’m afraid I’m seeing a potential problem here, if the source PDF is doublesided, \lastsectionpage from a reference may be an empty page. Many thanks for your help, Pablo
