使用emacs查中英文词典

测试环境: mandriva 2009.0 + emacs22
参考:
过程:
1).安装星际译王: sudo urpmi stardict
2).安装星际译王命令行工具: sudo urpmi sdcv
3).安装两套词典：中英和英中，当然你可以装的更多。
urpmi stardict-xdict-en-zh_CN
urpmi stardict-xdict-zh_CN-en
4).编辑~/.emacs文件，加入:

;; author: pluskid
;; 调用 stardict 的命令行程序 sdcv 来查辞典
;; 如果选中了 region 就查询 region 的内容，否则查询当前光标所在的单词
;; 查询结果在一个叫做 *sdcv* 的 buffer 里面显示出来，在这个 buffer 里面
;; 按 q 可以把这个 buffer 放到 buffer 列表末尾，按 d 可以查询单词
(global-set-key (kbd "C-c d") 'kid-sdcv-to-buffer)
(defun kid-sdcv-to-buffer ()
  (interactive)
  (let ((word (if mark-active
                  (buffer-substring-no-properties (region-beginning) (region-end))
                  (current-word nil t))))
    (setq word (read-string (format "Search the dictionary for (default %s): " word)
                            nil nil word))
    (set-buffer (get-buffer-create "*sdcv*"))
    (buffer-disable-undo)
    (erase-buffer)
    (let ((process (start-process-shell-command "sdcv" "*sdcv*" "sdcv" "-n" word)))
      (set-process-sentinel
       process
       (lambda (process signal)
         (when (memq (process-status process) '(exit signal))
           (unless (string= (buffer-name) "*sdcv*")
             (setq kid-sdcv-window-configuration (current-window-configuration))
             (switch-to-buffer-other-window "*sdcv*")
             (local-set-key (kbd "d") 'kid-sdcv-to-buffer)
             (local-set-key (kbd "q") (lambda ()
                                        (interactive)
                                        (bury-buffer)
                                        (unless (null (cdr (window-list))) ; only one window
                                          (delete-window)))))
           (goto-char (point-min))))))))

测试: 进入emacs,C-c d,输入单词，就可以看到结果了。q键退出。
