Question

是否可以获取列表并将其保存在变量中？我跑

(ido-completing-read "prompt: " '("one" "two" "three" "four" "five") nil nil "t")

和ido生成候选人列表{two | three}。我想要这样的东西

(setq my-desired-list (ido-completing-read-silent '("one" "two" "three" "four" "five") nil nil "t"))

执行后my-desired-list的值为("two" "three")。我为ido使用了复杂的设置，它为choices准备了非常特殊的过滤器，我想直接使用结果。

Answer 1

变量`ido-matches'将包含上次调用ido-completed-read时匹配的项目。所以这就是你想要的：

(defun ido-completing-read-silent (prompt choices initial-input)
  (ido-completing-read prompt choices nil nil initial-input)
  ido-matches)

(ido-completing-read-silent "prompt: " '("one" "two" "three" "four" "five") "t")
;; ("two" "three")

Answer 2

(defun eab/wrap-ido-completing-read ()
  (interactive)
  (ido-completing-read prompt choices nil nil initial-input)
  't)

(defun ido-completing-read-silent (prompt choices initial-input)
  (execute-kbd-macro (read-kbd-macro "M-: (eab/wrap-ido-completing-read) RET RET"))
  ido-matches)

(setq result (ido-completing-read-silent "prompt: " '("one" "two" "three" "four" "five") "t"))
;; result => ("two" "three")

我意外地找到了解决方案，并且可以在其他情况下使用，用于ido-completing-read等不同的交互功能。

注意：eval-expression应绑定到M-:。
