如果是org-agenda-mode，請用“ Args超出范圍：0，0”替換為更漂亮的消息

Question

我了解該錯誤消息表示沒有符合搜索條件的待辦事項：

org-agenda-find-same-or-today-or-agenda: Args out of range: 0, 0

有什么方法可以生成更漂亮的消息嗎？

(if (and (eq major-mode 'org-agenda-mode)
      (org-agenda-find-same-or-today-or-agenda: Args out of range: 0, 0) )
  (message "There are no events that match your search criteria."))

Answer 1

您可以使用condition-case來處理該標准錯誤：

 (if (and (eq major-mode 'org-agenda-mode)
          (condition-case err
              (org-agenda-find-same-or-today-or-agenda ...) ; Whatever args you need to pass.
            (args-out-of-range (error "There are no events that match your search criteria"))
            (error (error (error-message-string err)))))
     ...)

但是，聽起來您應該更正代碼，以防止出現該錯誤。 您不能在調用它之前測試到org-agenda-find-same-or-today-or-agenda to org-agenda-find-same-or-today-or-agenda的參數，並僅在該參數有效時才調用它？
