接近一年过去了,又突然想起这个主意来,可能是由于英文依旧没什么长进。
为了方便使用,把原来的 setq
整理成了一个 Minor Mode:
(defun bing-dict-eldoc-documentation-function ()
(let ((word (word-at-point)))
;; 太短的单词不查
(when (and word (> (length word) 4))
(bing-dict-brief word))
nil))
;; 注意一次只有一个 eldoc mode backend 生效
(define-minor-mode bing-dict-eldoc-mode
"Use bing-dict as backend of eldoc."
:lighter " Bing Dict"
(if bing-dict-eldoc-mode
(progn (setq-local eldoc-documentation-function
#'bing-dict-eldoc-documentation-function)
(eldoc-mode +1))
(setq-local eldoc-documentation-function #'ignore)
(eldoc-mode -1)))
