Hi list, 
I'm on my way to add a new (intrpreted) lisp dialect to org-babel, but
encounter a few difficulties. Here is my little testprogramm:

---------------------
#+tblname: tbl1
| 1 | 2 | 3 |
|---+---+---|
| 4 | 5 | 6 |
| 7 | 8 | 9 |


# external evaluation (no session)
#+srcname: pico-calc
#+begin_src picolisp :var tab=tbl1 :results value :hlines no 
  (+ (caar tab) (caar (cdr tab)))
#+end_src

# org-babel-error output:
[/tmp/babel-22634XBd/picolisp-script-22634K-K:1] !? (display (prog (let
(tab '((1 2 3) (4 5 6) (7 8 9))) (+ (caar tab) (caar (cdr tab))))))
display -- Undefined


#  with session
#+srcname: pico-calc
#+begin_src picolisp :var tab=tbl1 :results value :hlines no :session "p1"
  (+ (caar tab) (caar (cdr tab)))
#+end_src

#+results: pico-calc
[finishes with no output]

# session buffer:
(prog (let (tab '((1 2 3) (4 5 6) (7 8 9))) 
(+ (caar tab) (caar (cdr tab)))) )
"org-babel-picolisp-eoe"
-> 5
: -> "org-babel-picolisp-eoe"

---------------

I do not know where undefined 'display' comes from in the error message
- seems to be a org-babel internal thing. What can I do about that,
where do I have to look?

The session evaluation works already, but there is a problem with the
eoe string. If I don't use it, Emacs hangs forever - waiting for the
session to return? If I use it, the right value is calculated, but not
returned - because the eoe string is evaluated after the source-body?

Thanks for any tips
Thorsten

Sorry, I encountered the undefined 'display' in source code I copied
from ob-scheme, I deleted it, and then external evaluation succeeded -
but again without output. 
So I seem to be quite close, evaluation work and the right value is
calculated - but not returned yet. 

cheers

I assume you're using `org-babel-comint-with-output' to collect results?
If you're still having issues I'd suggest looking at some of the other
uses of this function in other ob-*.el files for example of ways that
it's use can be customized through code in the BODY section.

Hopefully ":results output" is already working and it is just ":results
value" which requires more work.  "results value" external evaluation
generally works by wrapping the body of the code block in a form which
will collect the result of the code block and print them to STDOUT.
Writing this wrapped body to a temporary file, evaluating this temporary
file, and then collecting the results from STDOUT.  I'd suggest
confirming that each of the above steps are working independently.

I hope the above helps.  Let me know if you run into any more issues.

yes, I use org-babel-comint-with-output more or less in the way it is
used in ob-scheme.el.

No, it isn't working - same thing as with :results value - no error
messages, but nothing is returned either and no output. I have to take a
deeper look at whats happening behind the scenes.

Thanks so far, I'll try to understand the workings of ob.el & friends
better and then hope to get things to work.
