Hi Matthew,
You're not missing anything obvious, there are two points which are
keeping this from succeeding.
First, emacs-lisp did not support the ":results output", however I've
just pushed up a patch which adds this support to emacs-lisp code
blocks.
Second, you have ":export output" below, when you should have ":results
output", and if you do want to change export options the header argument
is ":exports" (plural) not ":export". I really need to implement some
sort of highlighting to catch these small header-argument errors as
they're extremely common.
With the latest Org-mode the following should work.
#+begin_src emacs-lisp :results output
(let ((dog (sqrt 2))
(cat 7))
(print (format "%s %f" "Dog: " (eval dog)))
(print (format "%s %d" "Cat: " (eval cat)) nil)
(print "Fish."))
#+end_src
#+results:
:
: "Dog: 1.414214"
:
: "Cat: 7"
:
: "Fish."
Although I'd recommend returning the value as a list
#+begin_src emacs-lisp
(let ((dog (sqrt 2))
(cat 7))
`((dog ,dog)
(cat ,cat)
(fish)))
#+end_src
#+results:
| dog | 1.4142135623730951 |
| cat | 7 |
| fish | |
Cheers -- Eric
