That's partly normal: objc-mode is not in `which-func-modes'. But if you add `objc-mode' to which-func-modes, indeed the function name still doesn't show up in the mode-line (whereas it did in Emacs-23, so this is a regression). > Also, M-x imenu-add-menubar-index says: Error in > menu-bar-update-hook (imenu-update-menubar): (wrong-type-argument > integerp nil) I can indeed reproduce it (I used the src/nsfont.m file as sample ObjC file). Hopefully Alan can figure it out Stefan The imenu error has the following backtrace: Debugger entered--Lisp error: (wrong-type-argument integerp nil) match-beginning(nil) (funcall func (match-beginning langnum) (match-end langnum)) (setq str (funcall func (match-beginning langnum) (match-end langnum))) (while (re-search-backward cc-imenu-objc-generic-expression nil t) (setq langnum (if (match-beginning OBJC) OBJC (cond ((match-beginning Cproto) Cproto) ((match-beginning Cgeneralfunc) Cgeneralfunc) ((match-beginning Cnoreturn) Cnoreturn)))) (setq str (funcall func (match-beginning langnum) (match-end langnum))) (cond ((not (eq langnum OBJC)) (setq clist (cons (cons str (match-beginning langnum)) clist))) ((eq (aref str 0) 45) (setq str (concat "-" (cc-imenu-objc-method-to-selector str))) (setq methodlist (cons (cons str (match-beginning langnum)) methodlist))) ((eq (aref str 0) 43) (setq str (concat "+" (cc-imenu-objc-method-to-selector str))) (setq methodlist (cons (cons str (match-beginning langnum)) methodlist))) ((eq (aref str 0) 64) (setq classcount (1+ classcount)) (cond ((and (> (length str) implen) (string= (substring str 0 implen) "@implementation")) (setq str (substring str implen) str2 "@implementation")) ((string= (substring str 0 intflen) "@interface") (setq str (substring str intflen) str2 "@interface")) ((string= (substring str 0 prtlen) "@protocol") (setq str (substring str prtlen) str2 "@protocol"))) (setq str (cc-imenu-objc-remove-white-space str)) (setq methodlist (cons (cons str2 (match-beginning langnum)) methodlist)) (setq toplist (cons nil (cons (cons str methodlist) toplist)) methodlist nil)))) (let (methodlist clist (OBJC cc-imenu-objc-generic-expression-objc-base-index) (Cnoreturn cc-imenu-objc-generic-expression-noreturn-index) (Cgeneralfunc cc-imenu-objc-generic-expression-general-func-index) (Cproto cc-imenu-objc-generic-expression-proto-index) langnum (classcount 0) toplist str str2 (intflen (length "@interface")) (implen (length "@implementation")) (prtlen (length "@protocol")) (func (if (fboundp (quote buffer-substring-no-properties)) (quote buffer-substring-no-properties) (quote buffer-substring)))) (goto-char (point-max)) (while (re-search-backward cc-imenu-objc-generic-expression nil t) (setq langnum (if (match-beginning OBJC) OBJC (cond ((match-beginning Cproto) Cproto) ((match-beginning Cgeneralfunc) Cgeneralfunc) ((match-beginning Cnoreturn) Cnoreturn)))) (setq str (funcall func (match-beginning langnum) (match-end langnum))) (cond ((not (eq langnum OBJC)) (setq clist (cons (cons str (match-beginning langnum)) clist))) ((eq (aref str 0) 45) (setq str (concat "-" (cc-imenu-objc-method-to-selector str))) (setq methodlist (cons (cons str (match-beginning langnum)) methodlist))) ((eq (aref str 0) 43) (setq str (concat "+" (cc-imenu-objc-method-to-selector str))) (setq methodlist (cons (cons str (match-beginning langnum)) methodlist))) ((eq (aref str 0) 64) (setq classcount (1+ classcount)) (cond ((and (> ... implen) (string= ...

Brilliant diagnosis, absolutely right! Thanks. There're some pretty non-standard coding techniques in that file. ;-) Here's the final bit of the fix; please try it out if you haven't done already, and let me know whether it works fully. > BTW, the warning > ,---- > | ;; *Warning for cc-mode developers* > | ;; > | ;; `cc-imenu-objc-generic-expression' elements depend on > | .... > `---- > should be placed in front of cc-imenu-c++-generic-expression to be of > any use.

Hi Alan, Looks like c-defun-name still doesn't work right for objc-mode. Could you take a look at the patch from Jan Djärv in Bug#9032? Thanks.
