如果是org-agenda-mode，请用“ Args超出范围：0，0”替换为更漂亮的消息

Question

I understand that the error message means there are no todo entries that mach the search criteria:

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

Is there any way to generate a prettier message instead:

(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

You can use condition-case to handle that standard error:

 (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)))))
     ...)

However, it sounds like you should correct the code so that that error is prevented, instead. Can't you test the argument(s) to org-agenda-find-same-or-today-or-agenda before you call it, and call it only if the argument(s) is/are valid?
