Subject: 23.0.90; custom-set-faces inhibits faces differences between X11 and console clients
Date: Sun,  8 Feb 2009 11:52:19 +0100 (CET)

I use a main X11 emacs with clients (sometime X11, sometime console)
which attach to it. I want to have "black on white" X11 clients and
"white on black" console clients. (Actually, I don't care what Emacs
does with console colors, I just want it to preserves my terminal
defaults and I do use black background terminals.)

If I have *no* custom-set-faces section in my .emacs the default
configuration just does what I want.
- I start main X11 emacs (which is white on black)
- I start console clients (which are black on white, respecting the
  terminal)

... but I do need to customize faces, because I want the font in X11
to be smaller than the default. As soon as I add a
(custom-set-faces...) to my ~/.emacs, no matter _what_ I write into
it, the above doesn't work anymore. More precisely it seems that the
first kind of emacs which gets launched (X11 vs console) fixes once
and for all foreground and background colors. Hence:

- if I start the first emacs on X11, I'll the have "black on white"
  console clients
- if I start the first emacs on console, everything is fine again

My feeling is that there is a quite profund issue here of separation
of the initialization code, which looks like to be centralized while
it should be (to some extent) split and partly executed by clients.

... but more practically I'm also looking for workarounds :-)

TIA,
Cheers.

This is, indeed, a problem.  Tthe customize-face facility ought to allow
you to specify terminal-dependent face settings.  Hopefully, someone
will write such an enhancement, but this will probably not happen before
the upcoming 23.1 release.

One workaround that I can suggest is to reset the defface spec of the
face within your .emacs file, like this:

 (put 'font-lock-comment-face 'face-defface-spec nil)
 (defface font-lock-comment-face
   '((((class color) (background light))
      (:foreground "green"))
     (((class color) (background dark))
      (:foreground "yellow"))
     (t (:weight bold :slant italic)))
   "Font Lock mode face used to highlight comments."
   :group 'font-lock-faces)

The changes that you make this way will not apply to the first frame,
but they will apply to subsequent frames.

Do M-x customize-face RET font-lock-comment-face RET
Then middle-click on "state" and select "for all kinds of displays": you
can then give distinct settings for different circumstances.

Many thanks, starting from this tip I indeed found the correct
solution.

Actually, what I needed is to override *all* faces for console mode,
with respect to what happens in the X11 world. I just followed your
suggestion, using "'default" as the font face instead of
"'font-lock-comment-face".

So, in the end, it was not a bug, I'm therefore closing the bug with
this post.

Cheers.
