restrict buffers only to frame/window with vertico/consult

[fab6]

Hi,
coming from spacemacs I am used to have only buffers in each frame/window (sorry, I do not understand the difference yet in terms of persp).

With a plain vanilla evil-vertico-consult installation of persp I am having a complete sharing of all buffers and sometimes the open buffer in another window/frame changes when I active in a new frame/window.

Does anyone have a hint how I can get a restriction of the buffers only to the frames/windows? I have the feeling that this might be due to vertico/consult...

Thank you in advance!

Emacs Frame -- is a "System(OS) Window".
Emacs Window -- is a "pane" displaying a part of a buffer inside Emacs Frame.
Emacs Buffer -- is a buffer with text lines of a file.
Perspective -- is a collection of buffers.

So you want your buffer list to be "isolated" between Emacs Frames?
Or you want your perspectives list to be different between Emacs Frames?

thank you for the quick overview!

I want an isolated buffer list for each perspective. At the moment I have all buffers in each perspective when using switch-to-buffer or consult-buffer.

... and when I am writing this, I assume that this is normal and I have to use persp-switch-to-buffer to have isolation and that spacemacs does something in addition to use it in combination with e.g. consult-buffer. Is this right?
Thank you very much!

(defun compleseus/pre-init-persp-mode ()
  (spacemacs|use-package-add-hook persp-mode
    :post-config
    (setq
     spacemacs--persp-display-buffers-func 'spacemacs/compleseus-switch-to-buffer
     spacemacs--persp-display-perspectives-func 'spacemacs/compleseus-spacemacs-layout-layouts)))

I assume it is this spacemacs part which does it

[fab6]

with

(defun spacemacs/compleseus-switch-to-buffer ()
  "`consult-buffer' with buffers provided by persp."
  (interactive)
  (with-persp-buffer-list ()
                          (consult-buffer)))

and

(defvar spacemacs--persp-display-buffers-func 'ignore
  "Function to display buffers in the perspective.")
(defun spacemacs/persp-buffers ()
  "Call the function defined in `spacemacs--persp-display-buffers-func'"
  (interactive)
  (call-interactively spacemacs--persp-display-buffers-func))

Yes, spacemacs/compleseus-switch-to-buffer looks like it will work for you.
Other pieces of code seems to be spacemacs specific.

You may wish to bind this function to C-x b or other keys you like.
Something like:

(with-eval-after-load "persp-mode-autoloads"
  (with-eval-after-load "consult")
     (defun my/consult-switch-to-buffer ()
         "`consult-buffer' with buffers provided by persp."
         (interactive)
         (with-persp-buffer-list () (consult-buffer))
      (global-set-key (kbd "C-x b") #'my/consult-switch-to-buffer)))

There is also consult-buffer-filter as I see which you can customize if above function will not work.

[fab6]

I think this works quite well for me, thank you very much!

It works with consult, but I wonder if there's a way to get it working with just Vertico - i.e. the raw switch-to-buffer and kill-buffer commands.

Thank you! This works perfectly.

I made this solution:

(defvar persp-consult-source
    (list :name     "Persp"
          :narrow   ?s
          :category 'buffer
          :state    #'consult--buffer-state
          :history  'buffer-name-history
          :default  t
          :items
          #'(lambda ()
              (mapcar #'buffer-name
                      (persp-filter-out-bad-buffers)))))
(consult-customize consult--source-buffer :hidden nil :default nil)
(add-to-list 'consult-buffer-sources persp-consult-source)

This adds a new source for consult-buffer labeled "Persp", which shows a list of buffers for that perspective, if any.
If a "Persp" group is shown, the default buffer list is still shown in a group below it. To hide the default buffer list group if a Persp group is shown, set :hidden t in the consult-customize line above.

I like this setup because I can still access the default buffer list with b SPC and use consult-buffer for everything.
