emacs - dired-x：如何设置“也杀死...的缓冲区？” 是没有确认？

Question

如果你删除一个文件foo，dired-x你会被问到Kill buffer of foo, too?。我怎样才能跳过这个问题并总是用 回答它yes？

Answer 1

您可以建议该dired-delete-entry函数，以便在删除之前关闭任何文件缓冲区：

(defadvice dired-delete-entry (before force-clean-up-buffers (file) activate)
  (kill-buffer (get-file-buffer file)))

Elisp 手册将建议描述为“比重新定义整个函数更干净”，如果函数的定义在未来发生变化，它不太可能中断。

只需在 dired-x.el 中重新定义 dired-clean-up-after-deletion。

;; redefine the definition in dired-x.el, so that we are not prompted
;; to remove buffers that were associated with deleted
;; files/directories

(eval-after-load  "dired-x" '(defun dired-clean-up-after-deletion (fn)
  "My. Clean up after a deleted file or directory FN.
Remove expanded subdir of deleted dir, if any."
  (save-excursion (and (cdr dired-subdir-alist)
                       (dired-goto-subdir fn)
                       (dired-kill-subdir)))

  ;; Offer to kill buffer of deleted file FN.
  (if dired-clean-up-buffers-too
      (progn
        (let ((buf (get-file-buffer fn)))
          (and buf
               (save-excursion ; you never know where kill-buffer leaves you
                 (kill-buffer buf))))
        (let ((buf-list (dired-buffers-for-dir (expand-file-name fn)))
              (buf nil))
          (and buf-list
               (while buf-list
                 (save-excursion (kill-buffer (car buf-list)))
                 (setq buf-list (cdr buf-list)))))))
  ;; Anything else?
  ))
