在Emacs中,是否有访问最近打开的文件的命令?

基于pokita的回答,

(defun visit-most-recent-file ()
  "Visits the most recently open file in `recentf-list' that is not already being visited."
  (interactive)
  (let ((buffer-file-name-list (mapcar 'buffer-file-name (buffer-list)))
        most-recent-filename)
    (dolist (filename recentf-list)
      (unless (memq filename buffer-file-name-list)
        (setq most-recent-filename filename)
        (return)))
    (find-file most-recent-filename)))

我还没怎么测试过。

您可以使用recentf软件包来完成此操作:

(require 'recentf)
(defvar my-recentf-counter 0)
(global-set-key (kbd "<M-up>")
        (lambda ()
          (interactive)
          (setq my-recentf-counter (1+ my-recentf-counter))
          (recentf-open-most-recent-file my-recentf-counter)))

您可能会面临这样的问题,即“最近”列表中有您不感兴趣的文件(退出Emacs时保存的临时文件)。使用recentf exclude变量将这些文件从最近打开的文件列表中排除。
