emacs - 选择窗口时做一些事情

Question

我一直在浏览 the available hooks ，但当您切换窗口时，它们似乎都没有触发。

我想做的是为所选窗口激活次要模式:

(defvar active-window (frame-selected-window))

(defun active-window-switch (&rest _)
  (when active-window
    (with-selected-window active-window
      (active-window-mode nil)))
  (setq active-window (frame-selected-window))
  (active-window-mode t))

(define-minor-mode active-window-mode
  "Minor mode to distinguish the selected window."
  :global nil :group 'active-window :init-value nil :lighter " Active")

(add-hook 'window-configuration-change-hook #'active-window-switch)

(provide 'active-window)

我可以使用什么钩子(Hook)或函数来代替 window-configuration-change-hook(它只在我创建或退出窗口时触发)？

select-window 是一种在许多情况下内部使用的操作，可能在单个命令中使用数千次。您并不真正关心所选窗口的所有时间，而是仅在不运行命令时才关心。因此，更好的 Hook 位置是 post-command-hook。
