I don't see a problem with the default face definitions, at least not with display of search matches. (I've read the stack-overflow question, and I still am not sure what is the problem, since hl-line's background is rather light, and should be very different from any reasonable foreground.) Maybe you use some theme that is a factor here, or maybe your face customizations are involved. IOW, please show a complete recipe for reproducing the problem (it is also advisable to post that with "M-x report-emacs-bug RET", so the issue is recorded by the Emacs issue tracker). Thanks. ^ permalink raw reply [flat|nested] 8+ messages in thread

Yes, it is face related. And hl-line can dim good faces (often for highlight use). 1. Open emacs with “-Q” arg 2. In the scratch buffer, eval the following form: (progn (text-mode) (hl-line-mode) (defface test-face '((((class color) (background light)) :foreground "darkseagreen2" :background "black") (((class color) (background dark)) :foreground "darkolivegreen" :background "white") (t :inverse-video t)) "test face") (set-text-properties (point-min) (point-max) `(face test-face))) 3. Then move cursor across lines in buffer. Foreground color of text is the same as background color set by hl-line-mode, and text can’t be seen.

If you must set the foreground of the text the same as the background of the hl-line face, then customize the hl-line face to define the "distant foreground" color for it. E.g., I defined the "distant foreground" to be black, and the problem went away. ^ permalink raw reply [flat|nested] 8+ messages in thread

That's because you've chosen the distant foreground poorly. Look, you can always shoot yourself in the foot if you intentionally arrange your colors to produce bad contrast. That doesn't prove anything, certainly not that there's a bug or a missing feature. If you play with colors, you need to choose them carefully, that's all. ^ permalink raw reply [flat|nested] 8+ messages in thread

I think let hl-line ignoring text with non-default background color will be better. I will file a bug for it. Thanks.
