List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: emacs-devel-bounces+ged-emacs-devel=m.gmane.org@gnu.org Original-Sender: "Emacs-devel" Xref: news.gmane.org gmane.emacs.devel:209446 Archived-At: CEDET stickyfunc-mode appears to be broken after recent commits: e6681b27394a23979c3aef3925f78ef9cd75bd32 (=E2=80=9CNix more uses of = default-FOO variables (Bug#24946)=E2=80=9D), 73d47d22197175f08b2dd62e76d7138872e611d2 (=E2=80=9CRemove obsolete = default-FOO variables=E2=80=9D) Being enamored of stickyfunc-mode, I=E2=80=99m hoping that someone might = point me in the direction of a resolution. What I have so far is only a = partial workaround. Prior to the above commits, CEDET and stickyfunc-mode were enabled = globally via the following lines in my .emacs: (load (concat cedet-load-path "/semantic/loaddefs.el")) (semantic-mode) (mapc (lambda (mode) (funcall mode 1)) '(global-semantic-idle-summary-mode global-semantic-idle-completions-mode global-semantic-idle-scheduler-mode global-semanticdb-minor-mode)) global-semantic-stickyfunc-mode)) (This might be more properly done via customization, but the effect = should be the same) After commits removing the obsolete `default-FOO=E2=80=99 variables, = including `default-header-line-format', Emacs drops into the debugger on = startup as result of the above lines. One work around is to enable = stickyfunc-mode via major mode hooks. E.g., after commenting out the = last line above `global-semantic-stickyfunc-mode=E2=80=99, stickyfunc = mode can be enabled in C mode with the following hook: (defun c-mode-setup () "Adjust C mode environment." (semantic-mode) (make-local-variable 'header-line-format) (setq header-line-format '(:eval (list (propertize " " 'display '((space :align-to 0))) (semantic-stickyfunc-fetch-stickyline)))) (semantic-stickyfunc-mode)) (add-hook 'c-mode-common-hook #'c-mode-setup) Unfortunately, adding this to emacs-lisp-mode-hook causes Emacs to again = drop into the debugger on startup. In fact, whereas stickyfunc-mode = works with C code, it seems not to have worked with Lisp for a while now = (i.e., prior to removal of the `default-FOO=E2=80=99 variables). = Obviously it would help to identify the breaking commit, but I=E2=80=99m = not even sure what time frame to examine. In the mean time, perhaps someone could offer some insight into what=E2=80= =99s going on? Why did removal of the obsolete variable = `default-header-line-format=E2=80=99 wreck such havoc? Should I be = looking at CEDET code, or might the problem be of a more generic nature = that could be affecting other code that I haven=E2=80=99t come across = yet? Once enough information has been gathered, a bug report will be = submitted.
