emacs - emacs ido-buffer : 按目录分组缓冲区

Question

是否可以在某种树表示中查看按inbuffers分组的开放？directoriesemacs ido-buffer mode

Answer 1

“emacs ido 缓冲模式” ??

你的意思是ibuffer？如果是这样的话...

它不是分组¹，但按文件名排序是一个相当有用的近似值，默认情况下可用。

不幸的是（在我看来）dired 缓冲区不包括在内。您可以通过定义包含它们的排序器的变体来解决此问题，然后重新映射绑定：

(eval-after-load 'ibuffer
  '(progn
     (define-ibuffer-sorter filename/directory/process
       "Sort the buffers by their file name/process name."
       (:description "file name")
       (string-lessp
        (or (buffer-file-name (car a))
            (let ((dir (buffer-local-value 'dired-directory (car a))))
              (if (consp dir) (car dir) dir))
            (let ((pr-a (get-buffer-process (car a))))
              (and (processp pr-a) (process-name pr-a))))
        (or (buffer-file-name (car b))
            (let ((dir (buffer-local-value 'dired-directory (car b))))
              (if (consp dir) (car dir) dir))
            (let ((pr-b (get-buffer-process (car b))))
              (and (processp pr-b) (process-name pr-b))))))

     (define-key ibuffer-mode-map
       [remap ibuffer-do-sort-by-filename/process]
       'ibuffer-do-sort-by-filename/directory/process)))

¹按目录动态分组的功能会很漂亮。
