It is true that export takes place in a fresh Org-mode buffer, however the header arguments of Org-mode code blocks are guaranteed to be evaluated in the original buffer, so a trick like the following can be used to grab the original buffer. #+begin_src emacs-lisp :var buf=(buffer-file-name (current-buffer)) :exports both (message "buffer %S!" buf) #+end_src This issue should be given more prominence in the Org-mode manual, as it is a common source of confusion.
