When using ivy-display-function-fallback, ivy-posframe-dispatching-done cannot display hints with ivy-posframe-read-action-by-key

问题描述

使用 ivy-display-function-fallback 的时候，使用 C-o 打开 ivy-posframe-dispatching-done 后，虽然可以正常输入命令，但提示信息会显示为一个透明的矩形框，无法正常显示。

复现

1. 我设置 counsel-describe-variable 使用 ivy-display-function-fallback

   (setq ivy-posframe-display-functions-alist
     '((counsel-describe-variable . ivy-display-function-fallback)))

2. 打开 counsel-describe-variable
3. 使用 C-o 打开 ivy-posframe-dispatching-done
4. 发现显示为透明矩形框

可能的原因

我看了一下 ivy-posframe-dispatching-done 的定义

(defun ivy-posframe-dispatching-done ()
  "Ivy-posframe's `ivy-dispatching-done'."
  (interactive)
  (let ((ivy-read-action-function #'ivy-posframe-read-action-by-key))
    (ivy-dispatching-done)))

由于不使用 ivy-display-function-fallback 的命令没有这个问题，所以我怀疑 ivy-posframe-read-action-by-key 和 ivy-display-function-fallback 有冲突。 在试着把他改成 ivy-hydra-read-action 之后：

(let ((ivy-read-action-function #'ivy-posframe-read-action-by-key))
    (ivy-dispatching-done)))

确实可以正常显示了。 不过，这样的话不使用 ivy-display-function-fallback 的界面就会把提示显示在 minibuffer 中，风格不一致了。

(setq ivy-posframe-hide-minibuffer nil) 测试一下

I haven't used this package for a long time, so I will close this issue.
