Emacs:如何打破ido迷你冰箱？

我一般都在使用ido-switch-buffer,但有时当候选人太多时, helm-buffers-list更可取.但是打破偶像,召唤掌舵并重新输入丢失的信息是一件麻烦事.

所以我编写了这段代码,它直接在helm中重用ido中输入的信息:

(require 'helm-buffers)
(defun switch-to-helm-buffers-list ()
  "Emulate `helm-buffers-list' call with ido contents as initial input."
  (interactive)
  (let ((str (minibuffer-contents-no-properties)))
    (helm :sources '(helm-source-buffers-list
                     helm-source-ido-virtual-buffers
                     helm-source-buffer-not-found)
          :buffer "*helm buffers*"
          :keymap helm-buffer-map
          :truncate-lines t
          :input str)
    ;; (ido-exit-minibuffer)
    ))

(add-hook
 'ido-setup-hook
 (lambda()
   (define-key ido-buffer-completion-map "\C-i"
     'switch-to-helm-buffers-list)))

一个问题是ido留在迷你缓冲区中.当我ido-exit-minibuffer之前添加一个电话时helm,它没有被调用.当我在之后添加它时,它会重置窗口配置.我怎么解决这个问题？
