Setting color themes specific to a frame

Setting color themes specific to a frame

[Adam]

I am using emacs 24, and really enjoy the new color theme feature.  I
have one little issue, though.  I am using one emacs daemon instance,
and lots of instances.  Some using X11-Frames, some on plain terminals.
Is there any method to get the color theme just enabled on X11-frames,
but fall back to the default color theme on terminals - or, more
general - is there a method to set a color theme only for one specific
frame, without affecting the other frames?

I just had a similar problem, and solved it with some help from this
newsgroup:

I use the same setup like you - one daemon an lots of instances on plain
terminals and X, and use the following code to have different colors on
X:

,-------------------------------------------------------------------
| (defun tj-set-window-type-dependend-emacsclient-colors ()
|     "Sets emacsclient colors for X.
| Background-color is set to black and foreground-color to wheat for
| emacsclient on X"
|     (if (display-graphic-p)
|         (progn
|           (set-background-color "black")
|           (set-foreground-color "wheat"))))
| 
| (add-hook 'server-visit-hook
|           'tj-set-window-type-dependend-emacsclient-colors)
`-------------------------------------------------------------------

Instead of setting background-colors you might be able to change the
color-theme? 

This only works, when visiting a file when calling emacsclient, i.e.

,---------------------------------------
| exec emacsclient -c "/path/to/file.el"
`---------------------------------------

When using only the -c flag without a file argument, the *scratch*
buffer is visited, but the server-visit-hook is not called apparently.

If you are not using emacs --daemon, then I believe the solution lies
in the color-theme library. Setting color-theme-is-global to nil
should give you the behaviour you are looking for. For some hint you
can look here:

my emacs (GNU Emacs 24.0.93.1 (x86_64-unknown-linux-gnu, GTK+ Version
2.20.1)) does not have color-theme-is-global.  It is pretty much what I
want, though.

This does not work here.  This does not overwrite my color theme
settings.

BTW. changing the variables which store my color theme properties does not
work.  Emacs's load-theme, which is called in my init.el, examines the
theme variable and sets all the properties globally.  I need a method to
make load-theme set the theme properties frame-local, so I can call it
in my after-make-frame-functions.

Of course it doesn't. As I mentioned earlier, you have to use the
color-theme elisp library to get that working. :)

To clarify a bit more:

Emacs 24 does _not_ include color-theme.el or color themes, at all.  Emacs
instead created a similar feature that it calls "custom" themes.  The two are
_not_ the same.

Why Emacs did not incorporate color-theme.el or make its similar "custom" theme
feature be compatible with color themes, I cannot tell you.  But you need to
keep the two straight if you want to follow help offered by others on this list.

Heh, for some reason I misjudged from the subject that you're message
is about color-theme.el rather than emacs24 deftheme themes (or
whatever it is called). I consider my thread to be closed and will
participate in this one instead.

Here it link to my message:
 - http://lists.gnu.org/archive/html/help-gnu-emacs/2012-02/msg00237.html

It contains code for color-theme.el and deftheme themes and screenshots
of its effect.

What I like to archive is:
 1. determine whether deftheme themes support having frame specific
    settings.
 2. if not, if it is planned to support that.


Best,
Maik
