Makes normal color theme works on terminal

color-theme-approximate

Better degration for color theme in terminal. Inspired by: Vim's CSApprox http://www.vim.org/scripts/script.php?script_id=2390

Color themes usually defined in 24bit, while terminals normally only support 256 colors (8bit). Emacs' default degration algorithm doesn't work well in some systems, especially Linux. This package provides a better degration results by alter the default degrading algorithm.

Preview with Twilight Anti-Bright Theme by Jim Myhrberg

Note that I only encountered the problem in Linux, on Mac OS X the degration seems to work so you don't need this package.

Installation and Usage

Emacs 24

• Install the package via MELPA, or add the package's directory to load-path

• Add to your Emacs init file:

    (color-theme-approximate-on)
  

Note: I test this only on Emacs 24.1 and above. Pull requests for supporting other versions are welcomed.

color-theme-approximate's Issues

Approximations don't work on initial startup

Even with this fairly minimal init.el I simply can't get the approximation to work without having to do some manual work after starting emacs:

(require 'package)
(setq package-archives '(("melpa-unstable" . "http://unstable.melpa.org/packages/")))
(package-initialize)
(unless package-archive-contents (package-refresh-contents))
(unless (package-installed-p 'color-theme-approximate) (package-install 'color-theme-approximate))
(unless (package-installed-p 'sublime-themes) (package-install 'sublime-themes))
(color-theme-approximate-on)
(load-theme 'spolsky t)

Result after emacs -nw and the above init.el: default-approximated theme. Re-enabling the theme e.g. with M-x enable-theme causes the approximation to kick in, but I haven't found a way of getting it to work automatically. I tried using tty-setup-hook to delay calling load-theme but it didn't affect the end result.

emacs --version reports "GNU Emacs 24.4.1".

Am I doing something wrong?
