Ivy minibuffer is not updated when tying Korean chracters with the input method 'korean-hangul #3057
Description
I had trouble with ivy minibuffer update when typing Korean characters.
For example,
(1) Run (setq default-input-method 'korean-hangul)
(2) Run swiper.
(3) Type "C-\" to execute toggle-input-method.
(4) Type "dkssud" to write a Korean word "안녕".
You can see that the minibuffer is not updated until you type another key such as "<space>" or "C-n", although the word "안녕" occurs in the main buffer such as
안녕하세요.
만나서 반갑습니다.
나중에 연락 할게요.
안녕히 계세요.
However, I've finally found a solution for this problem, and share it.
(1) Copy the latest definition of hangul-insert-character and replace the old one with it.
(2) Modify ivy--minibuffer-setup to update the minibuffer when self-insert-command or hangul-delete-backward-char is called with the "korean-hangul" input method.
(defun self-insert-command--advice-for-korean (&rest args)
(when (equal current-input-method "korean-hangul")
(ivy--queue-exhibit)))
(defun hangul-delete-backward-char--advice-for-korean (&rest args)
(ivy--queue-exhibit))
(defun ivy--minibuffer-setup--advice-for-korean (&rest args)
(advice-add 'self-insert-command :after #'self-insert-command--advice-for-korean)
(advice-add 'hangul-delete-backward-char :after #'hangul-delete-backward-char--advice-for-korean))
(defun ivy--cleanup--advice-for-korean (&rest args)
(advice-remove 'self-insert-command #'self-insert-command--advice-for-korean)
(advice-remove 'hangul-delete-backward-char #'hangul-delete-backward-char--advice-for-korean))
(advice-add 'ivy--minibuffer-setup :after #'ivy--minibuffer-setup--advice-for-korean)
(advice-add 'ivy--cleanup :after #'ivy--cleanup--advice-for-korean)
