Thanks! It works. I have finished it. Here is the code.
(defvar sdcv-replace-template ",$|^`|\\.$|^'|'$|\\?$")
(defvar emacs-window-name "@EMACS@")
(defun display-message-seconds (message seconds #!optional attributes)
  "Display message for N seconds."
  (display-message message attributes)
  (make-timer (lambda () (display-message))
(defun sdcv-get-word ()
  "Get the word from current-word in emacs or selection or user input."
  (let* ((stream (make-string-output-stream))
         (process (make-process stream))
         (title "Enter String ")
         (word "")
         (result ""))
    (if (string= (window-name (input-focus)) emacs-window-name)
          (call-process process nil "emacsclient" "-e"
                        "(with-current-buffer (window-buffer 
(current-word nil t))")
          (setq word (get-output-stream-string stream))
          (setq word (string-replace "^\"(.+)\"\n" "\\1" word)))
      (setq word (string-replace sdcv-replace-template ""
(x-get-selection 'PRIMARY))))
    (setq word (string-replace sdcv-replace-template "" word))
    (setq title (concat title "(" word "):" ))
    (setq result (prompt-for-string title))
    (if (string= result "")
(defun sdcv-search ()
  "Search word with sdcv."
  (let* ((word (sdcv-get-word))
         (output (make-string-output-stream))
         (proc (make-process output))
         (errmsg "NO definite result. Try again.")
         (msg-attr '((position . (0 . 0)) (background . "LightGoldenrod1")
(foreground . "black"))))
    (call-process proc nil "sdcv" "-n" "--data-dir"
"~/.stardict/dic/stardict-langdao-ec-gb-2.4.2/" word)
    (setq output (get-output-stream-string output))
    (if (> (when (string-match "Found \(..?\) items" output)
             (string->number (expand-last-match "\\1")))
        (display-message-seconds errmsg 2 msg-attr)
      (display-message-seconds output 5 msg-attr))))
This is librep, it's like elisp, used in sawfish wm. Maybe it's
useless for you at all. Just have a look. ;)
