Can I filter all consult-buffer-sources when calling consult-buffer ?

[lyndhurst]

Hi,
I hope this question has not been asked already, but I did not find it.

I am not great at Elisp, but I am starting to understand it better, so I thought I would ask. I get how I can add sources to the consult-buffer-sources thanks to the documentation, but I do not think this is what I am looking for.

I am trying to restrict the list of buffers presented by consult-buffer to the current perspective from the persp-mode package. Which means that I would like to apply a filter to all defined consult-buffer-sources. Doom Emacs has a built-in function for that, but I lose all the great consult-buffer narrow actions, as well as some pretty useful configured sources like org-roam buffers.

I can produce the list of buffers I am interested in using (persp-buffers (get-current-persp)), but I do not see how I can use it. Is there a way to pass some kind of filter/validation function to the list of buffers before consult-buffers displays it ?

Thanks for your time, and a great package.

I found this piece of code that works pretty well for my purpose in a persp-mode issue.

I guess that instead of looking for a way to filter or validate buffers within the consult-buffer call, I could simply wrap this call in a context with a limited list of available buffers to begin with; like a let statement I think.

(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)))
