overlay (zipper -> red-black tree) 提案作者似乎棄坑了

之前嘗試,(setq cquery-sem-highlight-method 'overlay) 慢得不能忍( 感覺 'font-lock 也挺慢的) Andreas Politz 有個 對 overlay 使用數據結構的改進 (list zipper? → red-black tree) Re: Overlays as an AA-tree

某個 issue 中 Andreas Politz 提到他放棄了……(以及標題未更正,他的patch據說從 AA tree 改成 red-black tree 了)

(defconst my-cquery-packages '((cquery :location local)))

;; See also https://github.com/jacobdufault/cquery/wiki/Emacs
(defun my-cquery/init-cquery ()
  (require 'lsp-imenu)
  (use-package cquery
    :after lsp-mode
    :config
    ;; overlay is slow
    ;; WAIT https://lists.gnu.org/archive/html/emacs-devel/2017-05/msg00084.html
    (setq cquery-sem-highlight-method 'font-lock)
    ;; cquery.cl cquery--publich-semantic-highlighting is very slow
    (setq cquery-enable-sem-highlight t)
    (setq cquery-extra-init-params '(:enableComments 2 :cacheFormat "msgpack"))
    (add-hook 'c-mode-common-hook #'my-cquery//enable)))

嗯,好像实现起来难度太大,暂时是停滞了
