Re: [Color-theme-devel] Problems when switching themes.

[Donald Ephraim Curtis]

I figured out what my be part of the problem.

So one thing that is done by default is that the 'hl-line' face inherits from 
'highlight'.  Well, some themes remove this inheritance and set their own 
color.  Then when another theme gets loaded, which relies on the inheritance, 
the theme is off.



In my emacs config I do the following before changing the theme, so that I can 
get back to the defaults:
(fset 'color-theme-snapshot (color-theme-make-snapshot))

But even loading this snapshot does not restore the inheritance, it just sets 
the background to the originally inherited color



Further, I also tried loading a theme which added a "background" to 'hl-line'.  
If i go in and customize face the hl-line, and uncheck the background, and save 
for current session (or for future sessions) the background reappears.  So 
something is intercepting the call and overwriting that.  I assume that's 
color-theme.  Anyways, if I do a (set-face-attribute ...) then I can force the 
hl-line back to the proper inheritance.


So something seems off.
