Subject: bug#71601: 29.1; force-mode-line-update does not refresh names of tab-lines
Date: Sun, 16 Jun 2024 23:58:02 +0100 [thread overview]
Message-ID: <m25xu8sdfp.fsf@gmail.com> (raw)
In an `emacs -Q`, I tried the following code:
(progn
(tab-line-mode)
(setq-local tab-line-tab-name-function
(defun my/tab-name(tab &optional _)
(with-current-buffer tab
(concat (buffer-name) " " (format-time-string "%S"))))))
This works fine and I get the seconds after the buffer-name. However, I seem to have no way of updating the tab-line to cause the names to be refreshed (except to add or remove a tab).
The documentation of `force-mode-line-update` and the `:set` code of `tab-line-tab-name-function` suggest that calling `(force-mode-line-update t)` would do the trick, but on my Emacs, this does not work. Is this a bug or am I misunderstanding the documentation?
I apologize that I am unable to test this on Emacs 30.
