`default' in theme face specs

`default' in theme face specs

[Frank Terbeck]

Hey group,

with defining face specs for themes, the manual says:

  ‘default’
       This element of SPEC doesn’t match any terminal; instead, it
       specifies defaults that apply to all terminals. This element, if
       used, must be the first element of SPEC. Each of the following
       elements can override any or all of these defaults.

So I tried that, and it seems that the ‘override’ part doesn't quite
work as advertised. When this didn't seem to work, I created a minimal
theme, in which I'm doing this:

#+BEGIN_SRC elisp
    (custom-set-theme-faces 'foobar
       '(default ((default :slant normal
                           :weight bold
                           :foreground "white"
                           :background "black")
                  (t :foreground "blue"))))
#+END_SRC

As per the manual, I'd expect the "blue" foreground definition in the
‘t’ clause to override the default definition from the ‘default’ clause.
But that's not the case, the foreground colour is "white" after loading
the theme.

Am I misreading the manual, doing something wrong, or is this a bug?

In case it matters, "M-x version" returns:

  GNU Emacs 24.3.50.1 (x86_64-pc-linux-gnu, GTK+ Version 3.4.2) of
  2013-12-25 on jim, modified by Debian

This really doesn't seem to work as documented.  The info manual
says that overriding defaults is possible.

I first thought there is something wrong with your definition, but it
seems ok.  Also, when I change it to use

   (t :background "blue")

and enable your sample theme with lots of open frames, the background
flickers blue for a moment, then it gets black.

So I think you should make a bug report.

Thanks for your assessment. I just did that.
