Using org-babel with Scheme

Using org-babel with Scheme

[Leo Alekseyev]

Is anyone on the list using a recent org-babel with Scheme?  I
recently started working through SICP, and I'm running into issues
evaluating scheme src  blocks.  Org-babel error buffer pops up with
"ERROR: Wrong number of arguments to #<primitive-generic display>",
and the minibuffer prompts me for a lisp expression.  Is there
anything I need to configure beyond   (org-babel-do-load-languages
'org-babel-load-languages  '((scheme . t)))?

(Running latest org from git in Emacs 24; have Chicken scheme and
guile installed).

I loaded the ob-scheme.el directly (which should be the same as loading
it with org-babel-do-load-languages as above) and the following works
for me.

#+begin_src scheme
  (+ 1 1 1)
#+end_src

#+RESULTS:
: 3

I have guile installed and I have the `scheme-program-name' variable set
to "guile elsewhere in my .emacs init.  I imagine setting the above
variable should enable scheme evaluation.

Best,

while looking into this I did notice that when launching Geiser (a nice
slime-like scheme evaluator) I would sometimes crash my entire Emacs
process by pressing C-g when Geiser prompts for a scheme executable.  I
imagine this is unrelated to your problem, but was certainly surprising.

I am having both of these issues on Emacs 24.  Emacs crashes sometimes on
geiser and babel won't evaluate scheme code as Racket code despite setting
'scheme-program-name and 'org-babel-scheme-cmd to "racket". However, Guile
will work if both of those variables hold "guile".

Any new developments?

I haven't had time to look into this.  I imagine the first issue is a
problem with Geiser.  As for the second issue, note that the value of
the 'org-babel-scheme-cmd variable is only used when external execution
is requested (e.g., when session is set to "none"), otherwise session
evaluation is used (likely using Geiser if Geiser is installed).

Sorry I do not have more time to look into this at the moment.

I you feel like looking to the code, a good starting place would be to
run the command `edebug-eval-top-level-form' within the definition of
`org-babel-execute:scheme' in ob-scheme.el, then running a code block
and stepping through its evaluation.

Best,
