Load color-theme in init.el

Load color-theme in init.el

[Patrick Wang]

Hi,

I am using emacs 24.1.1 on Mac OS X Lion. I installed color-theme via emacs package and try to load a color theme in init.el. Therefore I added following lines into my init.el

 (require 'color-theme)
 (setq color-theme-is-global t)
 (color-theme-tty-dark)

However, after I restarted emacs, I got an error message "File error: Cannot open load file, color-theme," and color scheme wasn't changed.

It seems that init.el is evaluated before packages are loaded. If I evaluate init.el using "eval-buffer" after emacs is launched, color-theme can be found and color will be changed.

Can anyone give me a hand? Thanks!


Patrick

Patrick, did you ever figure out the solution to this problem?  I am having the same issue.  M - x eval-buffer works great for my .emacs file but it won't load regularly.

Thanks,

Nathan

What is this file "init.el"? Is it the (C-h v) site-run-file? If so, then it's the wrong place for the purpose of setting a colour theme. It might be OK to load here the Elisp code to handle colour themes, i.e., (require 'color-theme).

	The run-time load order is: 1. file described in
	this variable, if non-nil; 2. `~/.emacs'; 3. `default.el'.

When you look up the documentation of site-run-file you'll find some more hints.

The file "~/.emacs" is named by the variable user-init-file.

Hi guys, thanks for replying.  If anyone out there is still searching, I
finally figured out that apparently in Emacs 24 color-theme is (slightly?)
deprecated.  Instead you can load color themes with M - x load-theme, which
provides a bunch of choices.  I enjoy wombat, myself.  I'm using Emacs 24
for OS X.

Cheers,

Nathan

No, color-theme is not at all deprecated.  It has never been part of GNU Emacs,
so GNU Emacs cannot deprecate it.  It is a third-party library, color-theme.el,
and it is still available AFAIK.

What is unfortunate is that GNU Emacs adopted a name, "custom theme", that is so
close to "color theme", which already has a certain following.

Every few weeks someone posts here with questions that involve confusion between
the two.

(Emacs has had "custom themes" for a long time, but until Emacs 24 they had
nothing to do with colors (as in "color theme").  It is the combination of Emacs
24 adopting something similar to what color-theme.el offers plus its inclusion
of that new feature in the grab bag called "custom themes" that seems to lead to
the confusion.)

I see.  Thanks for clarifying.  In my original e-mail I also forgot to
mention that the advice of Peter Dyballa to use a .emacs for customization
was the correct advice.  Thanks Peter.  I got the idea to use
~/.emacs/init.el from the Emacs Starter Kit (
https://github.com/technomancy/emacs-starter-kit/ ).  Presumably it is no
substitute for .emacs.

Thanks again everyone,

Nathan

My advice is to use a separate file, the value of user option `custom-file', for
customizations that are written automatically when you use Customize (e.g., `M-x
customize-option').

That keeps such generated code away from any code that you write in your init
file (~/.emacs).  Let Customize fiddle with `custom-file', and keep your init
file for your own fiddlings.

I believe starting with the following commit:

  commit 2faa2c5d69f36c29cdd3b654f4cc9c4b89c81e5a
  Author: Chong Yidong <cyd@gnu.org>
  Date:   Mon Apr 23 02:04:54 2012 +0800

      * faces.el (face-spec-set): Stop supporting deprecated form of
        third arg.

color-theme stopped working properly with Emacs 24.  I switched to
custom-theme soon after, so I don't know if the situation has changed.

OK, good to know, I guess.  You are reporting that color-theme.el no longer
works with GNU Emacs.  Sorry to hear that.  I was reporting only that (a) GNU
Emacs cannot deprecate color-theme.el (by definition) and (b) color-theme.el is
still available.

But it should be straightforward to update color-theme.el to no longer use
`face-spec-set' (said without bothering to look at the code), should anyone want
to do that.  It should be enough to use `face-set-attribute' (and perhaps
`face-spec-chooose'), to replace using `face-spec-set'.

Of course, there is no guarantee that with just that change color-theme.el will
work with Emacs 24.
