There are many, many Babel examples, but I can't seem to find this functionality: A function in a Lisp code block in one org file is to be called from a Lisp code block in another org file. Is this possible? I know you can stick stuff into your personal "Library of Babel," but I just want to write a Lisp block that calls a function from another org file. I'll have SLIME running, of course. file1.org: ... #+begin_src lisp (defun foo () (...)) #+end_src is then called from. . . file2.org: ... #+begin_src lisp (defun baa () (foo)) #+end_src LB
