推荐答案

我使用以下内容.它与tcaswell的答案类似，但是处理缓冲区修改问题.

I use the following. It's similar to tcaswell's answer, but deals with the buffer modification issue.

(defun set-region-read-only (begin end)
  "Sets the read-only text property on the marked region.

Use `set-region-writeable' to remove this property."
  ;; See https://stackoverflow.com/questions/7410125
  (interactive "r")
  (with-silent-modifications
    (put-text-property begin end 'read-only t)))

(defun set-region-writeable (begin end)
  "Removes the read-only text property from the marked region.

Use `set-region-read-only' to set this property."
  ;; See https://stackoverflow.com/questions/7410125
  (interactive "r")
  (with-silent-modifications
    (remove-text-properties begin end '(read-only t))))
