Question

在VIM中，可以使用%在调用shell命令时指示当前文件名。任何人都可以指向我的文档方向，显示emacs中的等价物吗？

Answer 1

没有一个。但这是Emacs！所以这里：

(defun my-shell-command-on-current-file (command &optional output-buffer error-buffer)
  "Run a shell command on the current file (or marked dired files).
In the shell command, the file(s) will be substituted wherever a '%' is."
  (interactive (list (read-from-minibuffer "Shell command: "
                                           nil nil nil 'shell-command-history)
                     current-prefix-arg
                     shell-command-default-error-buffer))
  (cond ((buffer-file-name)
         (setq command (replace-regexp-in-string "%" (buffer-file-name) command nil t)))
        ((and (equal major-mode 'dired-mode) (save-excursion (dired-move-to-filename)))
         (setq command (replace-regexp-in-string "%" (mapconcat 'identity (dired-get-marked-files) " ") command nil t))))
  (shell-command command output-buffer error-buffer))

(global-set-key (kbd "M-!") 'my-shell-command-on-current-file)

只要迷你缓冲区希望你输入内容，你就可以使用它（警告：不能用于ido，但显然你总能用例如C-x C-f来解决这个问题）。您也可以在常规缓冲区中使用它。

(defun insert-filename-or-buffername (&optional arg)
  "If the buffer has a file, insert the base name of that file.
  Otherwise insert the buffer name.  With prefix argument, insert the full file name."
  (interactive "P")
  (let* ((buffer (window-buffer (minibuffer-selected-window)))
         (file-path-maybe (buffer-file-name buffer)))
    (insert (if file-path-maybe
                (if arg
                    file-path-maybe
                  (file-name-nondirectory file-path-maybe))
              (buffer-name buffer)))))

(define-key minibuffer-local-map (kbd "C-c f") 'insert-filename-or-buffername)

在我的情况下，使用来自自制软件的emacs 24 gui版本....我看到文件名是（小） - 模式栏左下角的第3项，就在迷你缓冲区的上方。

要查看我的位置，使用ido-mode我只需C-x C-f无需配置。

Emacs相当于VIM的'％`？
