Hi!
I'm still again using "which-func" and always find it very convenient!
I often compare files with "ediff" and I noticed that, in ediff-mode,
the keys ' ' 'DEL' 'j' change the point of buffers A B C
but the "which-func" part of their mode-line is not updated
because "which-func-update" updates only the "selected-window".
I first tried to change "which-func-update" using the commented line
(with "walk-windows") or my function "which-func-update-ediff-windows"
(see below). It worked correctly but refreshed the modeline only
after a second (the delay of the which-func-update-timer).
So, I found it more appropriate to use the "ediff-select-hook"
and added the following code (anywhere in "which-func.el"):
(defun which-func-update-ediff-windows ()
"Update the Which-Function mode display for the ediff'ed windows."
(when (eq major-mode 'ediff-mode)
;; In ediff-mode, the selected window is the "*Ediff Control Panel*"!
;; We should also update the other windows.
(when ediff-window-A
(which-func-update-1 ediff-window-A))
(when ediff-window-B
(which-func-update-1 ediff-window-B))
(when ediff-window-C
(which-func-update-1 ediff-window-C))))
(add-hook 'ediff-select-hook 'which-func-update-ediff-windows)
As I'm not familiar with patches, could you fix it, please?
