Think about this:
when is interned gray::original-input-stream-p in:
(ext:without-package-lock ("GRAY") (setf (fdefinition 'gray::original-input-stream-p) ...))
?
I'd propose to put these symbols in a user package: a specific gray-user, or they could as well be left in the current package.
fix-clisp.lisp:
(defpackage #:clim-mop (:use #:clos))
(eval-when (:compile-toplevel :load-toplevel :execute) (loop for sym being the symbols of :clim-mop do (export sym :clim-mop)))
(defpackage #:gray-user (:use))
(ext:without-package-lock ("GRAY")
;; CLIM expects INPUT-STREAM-P to be a generic function. (unless (typep #'input-stream-p 'generic-function) (setf (fdefinition 'gray-user::original-input-stream-p) #'input-stream-p) (fmakunbound 'input-stream-p) (defgeneric input-stream-p (stream) (:method ((stream stream)) (gray-user::original-input-stream-p stream))))
;; CLIM expects OUTPUT-STREAM-P to be a generic function. (unless (typep #'output-stream-p 'generic-function) (setf (fdefinition 'gray-user::original-output-stream-p) #'output-stream-p) (fmakunbound 'output-stream-p) (defgeneric output-stream-p (stream) (:method ((stream stream)) (gray-user::original-output-stream-p stream)))) )
An alternative could be to gensym them.
(defmacro make-generic (funame arguments) (let ((old (gensym (string funame))) (gargs (mapcar (lambda (arg) (if (consp arg) (first arg) arg)) arguments))) `(progn (setf (fdefinition ',old) (function ,funame)) (fmakunbound ',funame) (defgeneric ,funame ,gargs (:method ,arguments (,old ,@gargs))))))
(defpackage #:clim-mop (:use #:clos))
(eval-when (:compile-toplevel :load-toplevel :execute) (loop for sym being the symbols of :clim-mop do (export sym :clim-mop)))
(ext:without-package-lock ("GRAY")
;; CLIM expects INPUT-STREAM-P to be a generic function. (unless (typep #'input-stream-p 'generic-function) (make-generic input-stream-p ((stream stream))))
;; CLIM expects OUTPUT-STREAM-P to be a generic function. (unless (typep #'output-stream-p 'generic-function) (make-generic output-stream-p ((stream stream)))) )
