FYI. NickD offers me this code https://emacs.stackexchange.com/a/81604/15606:I don't think there's code in Emacs which does what you want, so if you really need to check proper pairing you're going to have to write the code. Stefan
(defun ndk/paren-match-p ()
(let ((mismatch (nth 4 (show-paren--default))))
(not mismatch)))
It seems working.
