The package look up in the with-redirected-y-or-n-p was broken because allegro expects keyword package names instead of strings. I changed (symbol-function (find-symbol "y-or-n-p-in-emacs" :swank)) to (symbol-function 'swank:y-or-n-p-in-emacs) because the former did not find the function even after exporting it properly from the swank package.  Not sure why that's broken but the latter works an is shorter. ---  This has been tested with Franz Lisp 8.2 64bit on Emacs 23.3.1  on Mac OSX Snow Leopard.  swank-allegro.lisp |    5 ++---  swank.lisp         |    3 ++-  2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/swank-allegro.lisp b/swank-allegro.lisp index 352859a..af6c54b 100644 --- a/swank-allegro.lisp +++ b/swank-allegro.lisp @@ -642,14 +642,13 @@    ;; As the CL:Y-OR-N-P question is (for some reason) not directly    ;; sent to the Slime user, the function CL:Y-OR-N-P is temporarily    ;; overruled. -  `(let* ((pkg       (find-package "common-lisp")) +  `(let* ((pkg       (find-package :common-lisp))            (saved-pdl (excl::package-definition-lock pkg))            (saved-ynp (symbol-function 'cl:y-or-n-p)))       (setf (excl::package-definition-lock pkg) nil             (symbol-function 'cl:y-or-n-p)   (symbol-function -                                             (find-symbol "y-or-n-p-in-emacs" -                                                          "swank"))) +                                             'swank:y-or-n-p-in-emacs))       (unwind-protect           (progn ,@body) diff --git a/swank.lisp b/swank.lisp index 024903c..e3a5a6d 100644 --- a/swank.lisp +++ b/swank.lisp @@ -65,7 +65,8 @@             #:set-default-directory             #:quit-lisp             #:eval-for-emacs -           #:eval-in-emacs)) +           #:eval-in-emacs +           #:y-or-n-p-in-emacs))  (in-package :swank) --
