[babel] some lisp/slime progress

[babel] some lisp/slime progress

[Erik Iverson]

Hello,

I recently posted on the inability of ob-lisp.el to
submit multiple forms to a running CL session and return
the result.

http://permalink.gmane.org/gmane.emacs.orgmode/37325

I have made some progress in fixing this, but it *required
defining a new function in SLIME, so I do not post this
as a patch to org-mode, since it depends on more than
org-mode*.  I don't know if this is something that truly
belongs in SLIME, so I may follow-up on that mailing list.

NB: this only works when :session is specified.

In SLIME swank.lisp, I define:

(defslimefun interactive-eval-region-orgmode (string)
   (with-buffer-syntax ()
     (with-retry-restart (:msg "Retry SLIME interactive evaluation request.")
       (list (format nil "~{~S~^~%~}" (eval-region string))))))


Then, in ob-lisp.el, apply the following patch.

diff --git a/lisp/ob-lisp.el b/lisp/ob-lisp.el
index 600b79e..2980cc8 100644
--- a/lisp/ob-lisp.el
+++ b/lisp/ob-lisp.el

       (if session
           ;; session evaluation
           (save-window-excursion
-           (cadr (slime-eval `(swank:eval-and-grab-output ,full-body))))
+	   (with-temp-buffer
+	     (insert full-body)
+	     (slime-eval

         ;; external evaluation
         (let ((script-file (org-babel-temp-file "lisp-script-")))
           (with-temp-file script-file

Then, things like the following work, where I assume you've already
started M-x slime.

#+begin_src emacs-lisp :session

(defvar test1 "test1 value")
(defvar test2 "test2 value")
test2

#+end_src

#+results:
: test2 value

Er, not emacs-lisp, just lisp... like the following

#+begin_src lisp :session

(defvar test1 "test1 value")
(defvar test2 "test2 value")
test2

#+end_src

#+results:
: test2 value

It looks like you've inserted an orgmode specific function into slime?
Maybe your slime patch could be changed to the introduction of a new
hook to which this org-mode specific function could be bound?  I imagine
the slime mailing list would know the best solution here.

I think it is reasonable for the :session header argument to be added to
an `org-babel-default-header-args:lisp' variable defined in ob-lisp.
That would remove the need to constantly specify :session.  This is
similar to the ob-clojure approach, which by default always uses a slime
session.

Great, I look forward to playing with this as soon as I find some
time...

Thanks for sharing -- Eric

Hi Erik,

I've had an opportunity to return to Babel support for common lisp
recently.  I just copied over the existing ob-clojure.el file to
ob-lisp.el and changed the clojure/swank specific parts.  The resulting
file seems to work after some initial tests and is exceedingly simple.

If this works for you as well, then I'd propose replacing the existing
ob-lisp.el with this new implementation.

Please let me know what you think.

Thanks -- Eric

This newly attached version includes some slight improvements over the
previous, namely,

- support for declaring the CL package in which evaluation takes place
- support for the ":results output" header argument
- and better handling of non-elisp-parsable results.

Best -- Eric
