Re: [O] org-babel for prolog

[Lawrence Bottorff]

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?

Yes, I typed it wrong. Thank you for bringing it to my attention. I also discovered that it is better to use `org-babel-do-load-languages’ instead as well. I will change the recommendation tomorrow.
