我通常让 hl-line 采用当前背景的略深一点的色调。这在编辑缓冲区中效果很好。然而,在某些缓冲区,例如 Org 日程表和 Gnus 组缓冲区,我希望使用更漂亮的颜色(代替光标)。
具体来说,我想在 gnus-hl-line 中更改 hl-line 的颜色,而不影响其他缓冲区中 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的建议得出最终解决方案。大部分时间使用中性高亮行,但有时候需要使用粗体高亮行,例如在Gnus和Org日程表中。
