Subject: [babel] some lisp/slime progress
Date: Sun, 20 Feb 2011 20:22:54 -0600	[thread overview]
Message-ID: <4D61CC7E.7030109@ccbr.umn.edu> (raw)

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
+	      `(swank:interactive-eval-region-orgmode
+	   	,(buffer-substring-no-properties (point-min) (point-max))))))
         ;; 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


Best Regards,
