bufler-list-switch-buffer-action not respected when using bufler-switch-buffer

[Leon-Plickat]

I set bufler-list-switch-buffer-action to '((display-buffer-same-window)), however when switching buffers with bufler-switch-buffer it still acts as if display-buffer-reuse-window is being used (other window displaying the selected buffer is focused, while I want to have the currently selected window display the buffer regardless of whether other windows in the current frame already do so).

According to package, the installed version is 20240312.552.

I searched a bit in the source but couldn't find the issue, I'll continue to look for it though.

Display buffer actions are complicated. Please try to reproduce the problem in a clean Emacs configuration. If you can, then please provide a step-by-step recipe.

[Leon-Plickat]

This can be reproduced in a clean configuration as follows:

Create a directory repro, containing init.el with the following contents (copied from my config):

(use-package package
  :defer t
  :init
  (package-initialize)
  (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
  :custom
  (package-native-compile t))

(use-package bufler
  :defer t
  :ensure t
  :custom
  (bufler-indent-per-level 4)
  (bufler-list-switch-buffer-action '((display-buffer-same-window)))

  :bind (("C-x C-b" . bufler)
	 ("C-x b" . bufler-switch-buffer)))

Then run emacs --init-directory=repro/. Wait until this emacs instance has launched and the packages are installed / compiled. Split via C-x 2. Execute M-x scratch-buffer RET. The focused window will now display the scratch buffer, the other the welcome splash buffer. Press C-x b to call bufler-switch-buffer and type *GN followed by Tab followed by RET. The window showing the splash buffer will be focused, the other window still displays the scratch buffer. The behaviour I would expect is that the focused window remains focused but switches it's buffer to the splash buffer, which is then displayed in both windows.

I hope this is useful enough, let me know if you need anything more.

Or does the "list" in bufler-list-switch-buffer-action imply it's not meant to change the behaviour of bufler-switch-buffer? I could not find a similar variable for that so I assumed this configured both.

[Leon-Plickat]

Ah, I think this is the responsible code for buffer switching (bufler-workspace.el). It does indeed not look at bufler-list-switch-buffer-action.

So this turns out to be a feature request rather than a bug report I guess, sorry for the noise.

That's correct, that option is for the buffer list, not for just any switching command.

We could add an option for that, but take a look at the option switch-to-buffer-obey-display-actions; maybe it would solve this problem for you.
