用 dmenu 补全 M-x
Code:
(defun dmenu-completing-read (prompt strings)
(let ((temp-stdin-buffer
(generate-new-buffer " *temp-stdin"))
(temp-stdout-buffer
(generate-new-buffer " *temp-stdout")))
(unwind-protect
(progn
(with-current-buffer temp-stdin-buffer
(dolist (s strings)
(insert s ?\n))
(shell-command-on-region (point-min)
(point-max)
(format "dmenu -p '%s'" prompt)
temp-stdout-buffer)
(with-current-buffer temp-stdout-buffer
(buffer-substring-no-properties (point-min)
(line-end-position)))))
(kill-buffer temp-stdin-buffer)
(kill-buffer temp-stdout-buffer))))
(defun dmenu-M-x (prefix command)
(interactive
(list current-prefix-arg
(intern
(dmenu-completing-read
"M-x"
(all-completions "" obarray #'commandp)))))
(and (commandp command) ; Prevent fail of dmenu
(command-execute command)))
实际用处不大，纯粹为了好玩。
