Dear Christine (and CC list),
Thank you!

That's very interesting way to solve the problem using LaTeX. Thank you
for sharing this. At the moment I'm leaning more towards solving it
using emacs lisp.

Thank you again. I'm thinking of a function like following. I'm using
comments to express the programming detail that I don't know how to do
yet.
(deffun org-latex-export-to-pdf-exam ()
(interactive)
# do some emacs lisp to add \printanswers to the end of org document
header, i.e., adding a line of #+LATEX_HEADER: \printanswers
(org-latex-export-to-pdf)
# do some emacs lips to move the foo.pdf to foo-with_solutions.pdf
# do some emacs lisp to add \noprintanswers to the end of org document
header, i.e., removing the line of #+LATEX_HEADER: \printanswers and
adding a line of #+LATEX_HEADER: \noprintanswers
(org-latex-export-to-pdf)
# remove the line of #+LATEX_HEADER: \noprintanswers
)
I don't know enough emacs lisp to fill in the details here for now.
However, I think this would be a way to do it within emacs. So each time
I call org-latex-export-to-pdf-exam, it would export two PDF files, one
with solutions and one without.
What do you think?
Yours sincerely,
Xianwen
