在Emacs中获取光标下的字体

Question

我一直在开发自己的自定义颜色主题,如果我能得到一个影响光标下文本的字体列表,那将非常有用.

类似Textmate的显示当前范围命令.

这样可以省去Mx自定义面部和查看可用选项的麻烦,猜测哪一个会影响我当前的单词.

有任何想法吗？

Answer 1

what-cursor-position 带有前缀参数显示面下的点,以及其他信息.

键盘快捷键是Cu Cx =

示例输出(face属性显示在最后一段中):

             position: 5356 of 25376 (21%), column: 4
            character: r (displayed as r) (codepoint 114, #o162, #x72)
    preferred charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x72
               syntax: w    which means: word
             category: .:Base, L:Left-to-right (strong), a:ASCII, l:Latin, r:Roman
          buffer code: #x72
            file code: #x72 (encoded by coding system undecided-unix)
              display: by this font (glyph code)
    nil:-apple-Monaco-medium-normal-normal-*-12-*-*-*-m-0-iso10646-1 (#x55)

Character code properties: customize what to show
  name: LATIN SMALL LETTER R
  general-category: Ll (Letter, Lowercase)
  decomposition: (114) ('r')

There are text properties here:
  face                 org-level-2
  fontified            t

Answer 2

Mx describe-face

Answer 3

您可以what-face使用以下代码进行定义:

(defun what-face (pos)
  (interactive "d")
  (let ((face (or (get-char-property (pos) 'read-face-name)
                  (get-char-property (pos) 'face))))
    (if face (message "Face: %s" face) (message "No face at %d" pos))))

之后,

M-x what-face

将打印当前点找到的面部.

(感谢thedz指出它what-face没有内置.)

Trey的脸是在正确的轨道上.它让我收到邮件列表上的一封电子邮件:

(defun what-face (pos)
    (interactive "d")
        (let ((face (or (get-char-property (point) 'read-face-name)
            (get-char-property (point) 'face))))
    (if face (message "Face: %s" face) (message "No face at %d" pos))))
