I am trying to pop to some (input) buffer when opening some (main)
buffer (for a gitter chat client, which is handy for Spacemacs
interactive support). Anyway, I am trying to use a local hook-function
which 'pops up' the input buffer. As I am using pop-to-buffer, the input
buffer should get selected. However, it does not get selected when using
a local hook, while it does work as expected when using the global hook.
I have used the following test code:
(defun pop-up ()
(pop-to-buffer "pop-up"))
(defun test ()
(interactive)
(with-current-buffer (get-buffer-create "test")
(add-hook 'window-configuration-change-hook #'pop-up)))
;; (add-hook 'window-configuration-change-hook #'pop-up nil t)
;; the following line triggers the `pop-up` hook function
(pop-to-buffer "test")))
;; evaluate code to remove the (global) hook
(remove-hook 'window-configuration-change-hook #'pop-up)
So you can start from emacs -Q, evaluate the above code, and do `M-x
test`, as expected the 'pop-up' buffer will be selected.
Now remove the hook (by evaluating the last line), then comment out the
global hook and uncomment the local hook. Again do `M-x test`, this
time, the 'test' buffer, wrongly and inconsistently, will be selected.
To me this behavior looks like a bug.
