That probably means the clojure block is returning nil as the value. I don't know what it means to return something in clojure, but here is what you have to do with Python, for example.
#+BEGIN_SRC python :results value code [1, 2, 3] #+END_SRC #+RESULTS: #+begin_src python None #+end_src You have to explicitly return a value to see it. #+BEGIN_SRC python :results value code return [1, 2, 3] #+END_SRC #+RESULTS: #+begin_src python [1, 2, 3] #+end_src John ----------------------------------- Professor John Kitchin (he/him/his) Doherty Hall A207F Department of Chemical Engineering Carnegie Mellon University Pittsburgh, PA 15213 412-268-7803 @johnkitchin http://kitchingroup.cheme.cmu.edu On Thu, Jun 24, 2021 at 10:31 AM Johannes Brauer <bra...@nordakademie.de> wrote: > What about :results code > The default is a elisp code block so you get syntax coloring > > > That works fore lisp: > > #+begin_src elisp :results code > (list 1 2 (+ 1 2)) > #+end_src > > #+RESULTS: > #+begin_src elisp > (1 2 3) > #+end_src > > But with Clojure I get > > #+begin_src clojure :results code > (list 1 2 (+ 1 2)) > #+end_src > > #+RESULTS: > #+begin_src clojure > nil > #+end_src > >
