如何在某个位置用缓冲区文件杀死所有缓冲区？

如何在特定位置用缓冲区文件杀死所有缓冲区？

例如，我想用 c:...\dev 中的缓冲区文件和所有到 c:...\dev 的 dired 缓冲区子目录杀死所有缓冲区

或者换句话说，如何遍历 emacs 中所有缓冲区的文件或目录？

谢谢@David @phils。我在 ibuffer

中组合了 elisp 代码和函数

(mapc (lambda (buffer)
    (let ((file-name
           (or (buffer-file-name buffer)
               (with-current-buffer buffer
                 (and
                  (boundp 'dired-directory)
                  (stringp dired-directory)
                  dired-directory))
               )))
      (when (and file-name
                 (string-match "^c:.*?\\dev" file-name))
        (kill-buffer buffer))))
  (buffer-list))

从 elisp 使用：

(mapc (lambda (buffer)
        (let ((file-name
               (or (buffer-file-name buffer)
                   ;; In dired-mode we need `dired-directory' which
                   ;; might be a list and may not be fully expanded.
                   (with-current-buffer buffer
                     (and (eq major-mode 'dired-mode)
                          (expand-file-name
                           (if (consp dired-directory)
                               (car dired-directory)
                             dired-directory)))))))
          (when (and file-name
                     (string-match "^c:\\.*\\dev" file-name))
            (kill-buffer buffer))))
      (buffer-list))
