如何获得emacs背景颜色

Question

具体来说,我试图使下面的代码工作:问题是term-default-bg-color(接近代码块的末尾)似乎并不普遍存在所以我试图获得emacs背景颜色并使用它

(defun low-lock-face-phrase-buffer (regexp )
  "Set face of each match of phrase REGEXP to term-default-bg-color to dim it;
  internally it calls to hi-lock-face-phrase-buffer" 
  (interactive
   (list
    (hi-lock-regexp-okay
     (hi-lock-process-phrase
      (read-regexp "Phrase to dim" (car regexp-history))))))
  (unless hi-lock-mode (hi-lock-mode 1))
  (hi-lock-set-pattern regexp 'term-default-bg-color))

Answer 1

一般来说,背景颜色只是(face-attribute 'default :background).

但是,如果您想要在特定位置显示背景颜色,可能会显示一个或多个面,则使用eyedrop-background-at-point库中的函数eyedropper.el.
