Re: [O] Conditional source-block execution based on LaTeX document class?

[Eric Schulte]

Hi James,

Maybe you could do something like the following...

#+name: export-hdr-arg-backend-dep
#+begin_src emacs-lisp
(message "do stuff")
#+end_src

#+call: export-hdr-arg-backend-dep() :exports (if (eq 
org-export-current-backend 'beamer) "none" "results")

Best,
