ibuf-ext.el not loaded

[ehrt74]

on my system i've been having trouble getting perspective to work with ibuffer. i have added the following ibuffer hook:

 (add-hook 'ibuffer-hook
        (lambda ()
          (persp-ibuffer-set-filter-groups)
          (unless (eq ibuffer-sorting-mode 'alphabetic)
            (ibuffer-do-sort-by-alphabetic))))

on opening ibuffer the following error occurs:

persp-ibuffer-generate-filter-groups: Symbol’s function definition is void: ibuffer-remove-duplicates

this seems to be because ibuf-ext.el is not loaded (locate-library confirms this).

to fix this problem i've added a (require 'ibuf-ext) to my init.el. maybe this would be better added somewhere in the perspective code?

I tried fixing this in 460311b, but since I don't use ibuffer regularly, I'm not sure how to test the fix correctly. It should be in MELPA now. Could you please check if that works?

perfect! it works on my system :)

my use-package for perspective was this

  (use-package perspective
      :ensure t
      :bind (("C-x k" . persp-kill-buffer*)
       ("s-[" . persp-prev)
       ("s-]" . persp-next))

      :init
      (persp-mode)
      (setq persp-state-default-file (expand-file-name ".persp" user-emacs-directory))
      (add-hook 'ibuffer-hook
        (lambda ()
          (require 'ibuf-ext) ;; <- fusxado por certigi ke 'ibuf-ext estas sxargita
          (persp-ibuffer-set-filter-groups)
          (unless (eq ibuffer-sorting-mode 'alphabetic)
            (ibuffer-do-sort-by-alphabetic))))
      (add-hook 'kill-emacs-hook #'persp-state-save)
      (persp-state-load persp-state-default-file)
      (persp-switch "main")
      :custom
      (persp-mode-prefix-key (kbd "C-x x")))

i commented out (require 'ibuf-ext), ran org-babel-tangle and restarted. ibuffer works!!!

thank-you!
