customize themed face

customize themed face

[Joost Kremers]

Hi,

I'm trying to customize the face `bm-face` (from the bm.el package from
<https://github.com/joodland/bm>), but somehow I can't get rid of the
fore- and background colors. I'm using the anti-zenburn-theme, which
somehow seems to have something to do with the problem.

If I run `emacs -Q` and then load the file bm.el, I can use Customize to
unset the colors and add an underline. If I load anti-zenburn-theme.el,
the colors are set to those specified in the theme and they stay that
way, even if I uncheck them in the Customize buffer.

Only doing 

(set-face-attribute 'bm-face nil :underline t :foreground nil :background nil)

works, i.e., explicitly setting fore- and background to nil.

Is this expected behaviour for themed faces? Or should I report this as
a bug?

Emacs is 24.3, BTW.

I don't get it - why are you setting *both* fore- and
background to nil? Won't that mean that text in that
"face" can't be read?

This is how I set all my faces. I don't like custom (in
particular the fullbuffer UI) but that doesn't mean I
can't use it in a way I like it, in my .emacs:

(custom-set-faces
 ;;; DIRED
 '(dired-directory ((t (:foreground "blue"    :bold t))))
 '(dired-header    ((t (:foreground "green"   :bold t))))
 '(dired-ignored   ((t (:foreground "magenta" :bold nil))))
 ; etc.
)

If it is changed and evaluated, change is instantaneous.

I don't know if this related to your question, though.

No, it means that the default fore- and background color are used. It
should be the same thing as unchecking the boxes for fore- and
background color in Customize, but for some reason, when I do that, the
themed color remain.

OK, but why don't you just set the color to whatever
color you like?

Because I don't want to. ;-) I want bm-type bookmarks to be marked with
underline, but the colors of the characters I'm putting the bookmark on
should remain the same, whatever they are. This works as long as I don't
load the anti-zenburn theme (I haven't tried with other themes,
something I probably should do... I just wanted to know if this is a
known problem or not.)

Aha, OK. I didn't even know there were themes for Emacs!
