如何在 emacs 中使用 dictem？

我已经安装了 Lubuntu 存储库中的 dictem，但我不知道如何运行它。我想知道它的基本用法、如何添加/删除词典、如何查找 Wiki、Wiktionary、forvo 等网络资源进行发音等。

我目前正在使用 GoldenDict，但如果 emacs 中也有类似的功能就更好了，这样查找结果就可以轻松地在其他文档中使用。

我一直使用 emacs 中的 dict 插件dictem。事实上，dictem README 中有非常好的信息。无论如何，这是我的设置。在使用此代码之前，请安装下面列出的依赖项。顺便说一句，此设置仅联系本地主机服务器，而不联系 Web 资源。

;; ubuntu packages needed
;; dict - client installed by default
;; dictd - server
;; dict-wn - Wordnet dictinory
;; any other dicts you want

(when (executable-find "dictd")            ; check dictd is available
   (require 'dictem))


(setq dictem-server "localhost")
(setq dictem-user-databases-alist
      `(("_en-en"  . ("foldoc" "gcide" "wn"))))

(setq dictem-use-user-databases-only t)

(setq dictem-port   "2628")
(dictem-initialize)

(setq dictem-default-strategy "word")
(setq dictem-use-user-databases-only t)

;; For creating hyperlinks on database names
;; and found matches.
(add-hook 'dictem-postprocess-match-hook
          'dictem-postprocess-match)

;; For highlighting the separator between the definitions found.
;; This also creates hyperlink on database names.
(add-hook 'dictem-postprocess-definition-hook
          'dictem-postprocess-definition-separator)

;; For creating hyperlinks in dictem buffer
;; that contains definitions.
(add-hook 'dictem-postprocess-definition-hook
