Hi Dov,

Yes, see the documentation of the :exports header argument.


Header arguments such as :exports can be set in various different ways.


The difference in behavior you see stems from the value of the variable
org-babel-default-header-args, and the language-specific versions of
that variable. Note below that although :exports in general defaults to
"code", for ditaa this default is overridden to "results". The reason
for which was that ditaa code is typically going to be there to generate
graphics, whereas that is only occasionally true for python.

#+begin_src emacs-lisp :results pp

: ((:session . "none")
:  (:results . "replace")
:  (:exports . "code")
:  (:cache . "no")
:  (:noweb . "no")
:  (:hlines . "no")
:  (:tangle . "no"))

#+begin_src emacs-lisp :results pp

: ((:results . "file")
:  (:exports . "results"))

#+begin_src emacs-lisp :results pp

: nil
