I'm just a Prolog beginner, but this:
#+begin_src prolog
edge(a,b).
edge(a,e).
edge(b,d).
edge(b,c).
edge(c,a).
edge(e,b).
tedge(Node1,Node2) :-
edge(Node1,SomeNode),
edge(SomeNode,Node2).
#+end_src
keeps giving me this:
executing Prolog code block...
executing Prolog source code block
org-babel-execute:prolog: Wrong type argument: char-or-string-p, ni
BTW, should it be
(eval-after-load 'org
'(require 'ob-prolog))
or
(eval-after-load "org"
'(require 'ob-prolog))
. . . org in quotes?
