如何在不重新啓動Emacs的情況下查看修改變量ibuffer-saved-filter-groups的結果？

Question

我試圖修改alist ibuffer-saved-filter-groups。但是在我退出ibuffer並評估setq語句之後，當我運行M-x ibuffer時，ibuffer類別不會改變。只有當我徹底重新啓動emacs時纔會反映這些更改。

即修改此列表，需要一個emacs的完整的重新啓動才能生效：

(setq ibuffer-saved-filter-groups 
    (quote (("default" 
      ("Org" ;; all org-related buffers 
     (mode . org-mode) 
     (mode . ruby-mode)) 
      ("Mail" 
       (or ;; mail-related buffers 
       (mode . message-mode) 
       (mode . mail-mode) 
       ;; etc.; all your mail related modes 
       )) 
      ("Emacs" 
       (or 
       (mode . emacs-lisp-mode) 
       )) 
     ("Scratch" 
       (or 
       (mode . lisp-interaction-mode) 
       )) 
      ("ERC" (mode . erc-mode)) 
     ("Consoles" 
     (mode . term-mode)) 
     ("Help" (or (name . "\*Help\*") 
      (name . "\*Apropos\*") 
      (name . "\*info\*") 
      (name . "\*Compile-Log\*") 
      (name . "\*Backtrace\*") 
      (name . "\*Messages\*")))))))

您可以殺死*Ibuffer*緩衝或選擇要使用的過濾器組：

M-x ibuffer 
/R "default"
