help for editing text.

Here's what works for me...
(defun edit-obj (obj associated-window &optional pkg)
(let* ((*package* (if (symbolp obj)
*package*)) ;; just so package prefix is not printed.
(df (with-output-to-string (s) (pprint obj s))))
(clim::with-menu (str associated-window)
;; set to some arbitrary "nice" size, LUCID comes up with a very
;; small one by default.
(clim::window-set-inside-size str 700 300)
(setf (clim::stream-text-margin str) (clim::window-inside-width str))
;; just to make sure pointer is in the window...
(clim::stream-set-pointer-position* str 100 100)
(clim::with-input-editing (str :initial-contents df)
#+excl (mp::process-run-function "OLD KLUDGE" #'bloody-kludge str)
#+lcl (lcl::make-process :name "OLD KLUDGE" :function #'bloody-kludge
:args (list str))
(defun bloody-kludge (str)
;;; AAAAAAAARGH, MAJOR KLUDGERY to get text displayed
(sleep 1) (clim::window-refresh str))
This works on a SUN with either Allegro or Lucid CL. Also, I think
for LUCID, you need to be careful about the argument to
:initial-contents, if it is a well-formed (expr) list, it may return
immediately, so you may want to do something like (subseq obj 0 (1-
(length obj))) after you've converted obj into a string.
Unfortunately you won't get a cursor. Since this is really primitive,
if you have something that is more than one line long, you'll prolly
have to write something that breaks it up reasonably.
Hope this helps.
