Emacs hl-line:在本地更改颜色

我通常让hl-line采用稍暗的当前背景色调。这在编辑缓冲区时效果很好。但是,在某些缓冲区中,例如Org议程和Gnus组缓冲区,我想使用更漂亮的颜色(代替光标)。

具体来说,我想改变gnus-hl-line 中hl-line的颜色,而不会影响其他缓冲区中hl-line的颜色。

(add-hook 'gnus-summary-mode-hook 'gnus-hl-line)
(add-hook 'gnus-group-mode-hook 'gnus-hl-line)

(defun gnus-hl-line ()
  (hl-line-mode 1)
  (set (make-local-variable 'line-move-visual) nil)
  (setq cursor-type nil))

谢谢,

使用Phil的建议的最终解决方案。它大多数时间使用中性hl线,但有时可以看到粗体hl线,例如在Gnus和Org议程中

;; From emacs-wiki:
(defun shade-color (intensity)
  "print the #rgb color of the background, dimmed according to intensity"
  (interactive "nIntensity of the shade : ")
  (apply 'format "#%02x%02x%02x"
         (mapcar (lambda (x)
                   (if (> (lsh x -8) intensity)
                       (- (lsh x -8) intensity)
                     0))
                 (color-values (cdr (assoc 'background-color (frame-parameters)))))))

(defface hl-line-highlight-face
  '((t :inherit highlight))
  "Face for highlighting the current line with `hl-line-fancy-highlight'."
  :group 'hl-line)

  (hl-line-mode))

hl-line-face是一个包含要用于hl-line-mode的面的变量,因此我们可以在这些模式下将该变量设为缓冲区 - 并为其指定一个新的自定义面。

您可以像这样创建一个新面孔:

(defface gnus-hl-line
  '((t :inherit hl-line))
  "Face for highlighting the current line with `gnus-hl-line'."
  :group 'hl-line)

并使用 M-x customize-face RET gnus-hl-line RET

进行自定义

然后在gnus-hl-line函数中添加此内容(在调用hl-line-mode之前看起来最合理)。

(set (make-local-variable 'hl-line-face) 'gnus-hl-line)
