如何在Emacs中设置括号的颜色？（如圆括号、花括号、方括号等）

Question

我想指定自定义颜色主题中{}、()和[]的颜色。这是否可能？

尝试：

(font-lock-add-keywords nil '(("\\([\{\}\\[\]\(\)]+\\)" 1 font-lock-keyword-face prepend)))

仅适用于父级匹配：

评估以下表达式或将其放入您的.emacs文件中：

(custom-set-faces
 '(show-paren-match ((t (:background "blue"))))
 '(show-paren-mismatch ((((class color)) (:background "red" :foreground "white")))))

只有当光标位于括号上方时，它才会起作用。或者我漏掉了什么？ - MDCore

哦，你一开始就想要着色。我编辑了答案。试试建议的那个。 - OTZ

我可以让它只在我编辑主题的缓冲区中着色圆括号，而且有时候只着色圆括号吗？如果我将其添加到主题中并打开另一个emacs，它什么也不做。奇怪？！ - MDCore

@MDCore 已编辑。你能再试一次吗？ - OTZ

仍然没有得到乐趣。我已经更新了问题，并提供了完整的源代码。 - MDCore

你可以使用彩虹括号模式(rainbow-delimiters mode)，在Emacs24包系统中，你可以从MELPA安装它，或从以下链接下载rainbow-delimiters.el：

emacswiki-RainbowDelimiters

将rainbow-delimiters.el放置在emacs的加载路径(load-path)中

在你的.emacs文件中编写初始化代码(init code):

(require 'rainbow-delimiters)

(global-rainbow-delimiters-mode)

这导致出现以下错误：符号的函数定义无效：global-rainbow-delimiters-mode。 - Zelphir Kaltstahl
