question about :results scalar

question about :results scalar

[Robert McIntyre]

hi --- I'm working through the org manual and have run into a strange
problem with ":results scalar"

M-x org-version gives "Org-mode version 7.5 (release_7.5.288.gcec8.dirty)".

I've made a code block using #+begin_src emacs-lisp :results scalar,
with the source just being '(1 2 3), but I get back an org-table
instead of the expected : (1 2 3). what am I doing wrong?

a minimal example file can be found here:
 https://gist.github.com/1034648

I also get the same thing when trying the stable Org-mode version 7.5.

sincerely,
--Robert McIntyre

Hi Rob,

Thanks for pointing this out.  The emacs-lisp interaction is so simple
we apparently never implemented checks which are routine in other
languages.  I just pushed up a fix to the git repository so the
":results scalar" header argument combination should now be respected
for emacs-lisp.

Thanks -- Eric

Excellent --- I'm glad that the interaction with emacs-lisp is straightened
out!

I've been continuing working with source blocks and the same problem seems
to be present with clojure interaction.

#+begin_src clojure :exports both :results scalar
(ns whatever)
(defn works? [] true)
#+end_src

#+results:
| function | whatever/works? |


The clojure repl would normally output the text

"#'whatever/works?"

but this is being converted into an org-mode table, ignoring the :results
scalar declaration.

futrhermore, the same test with emacs-lisp also fails as in this example


#+begin_src clojure :results scalar
'(1 2 3)
#+end_src

#+results:
| 1 | 2 | 3 |

-------------------------------------------------------------------------------------------------------


also, although :results scalar still works,  :results verbatim does not work
quite yet for emacs-lisp

#+begin_src emacs-lisp :results scalar
;;(debug t nil)
'(1 2 3)
#+end_src

#+results:
: (1 2 3)


#+begin_src emacs-lisp :results verbatim
;;(debug t nil)
'(1 2 3)
#+end_src

#+results:
| 1 | 2 | 3 |



M-x org-version returns:
Org-mode version 7.5 (release_7.5.414.g56de5.dirty)


Thank you so much for your prompt attention to my last comments!

sincerely,
--Robert McIntyre

Hi Robert,

I've added "verbatim" to the Emacs-lisp support.  The attached patch
should fix the Clojure behavior as well, however since I no longer have
a working clojure install on my system, would you mind confirming it's
behavior before I push it to the git repository?

Thanks -- Eric

Subject: [PATCH] ob-clojure: respect the ":results scalar" header argument

* lisp/ob-clojure.el (org-babel-expand-body:clojure): Move pretty
  printing out of body expansion.
  (org-babel-execute:clojure): Now holds pretty printing logic, and
  respects the ":results scalar" header argument
