在Emacs中更改文本外观：重叠工作，文本属性不 [英] Changing text appearance in Emacs: overlays work, text properties don't

问题描述

我今天在Emacs中试用了文本属性。如果我将光标放在一条文字上，然后使用 M - ：执行以下代码，该行将以粗体重新显示。

I've been experimenting today with text properties in Emacs. If I position the cursor on a line with some text on it and then execute the following code with M-:, the line is redisplayed in bold.

(overlay-put
 (make-overlay
  (line-beginning-position)
  (line-end-position))
 'face 'bold)

但是，如果我擦除叠加层使用（remove-overlays）并执行以下代码，没有任何反应（除了nil一词出现在minibuffer中）。

If, however, I wipe out the overlay with (remove-overlays) and execute the following code, nothing happens (except that the word "nil" appears in the minibuffer).

(put-text-property
 (line-beginning-position)
 (line-end-position)
 'face 'bold)

从我迄今收集的内容中，我期望这两个片段应该产生相同的视觉效果。为什么不这样？

From what I've gleaned so far, I'd expect that these two snippets should produce the same visual results. Why don't they?

推荐答案

当 font-lock-mode 开启， face 属性将被覆盖。

When font-lock-mode is on, the face attribute will be overridden. Try font-lock-face instead:

(put-text-property
 (line-beginning-position)
 (line-end-position)
 'font-lock-face 'bold)
