如何设置我的Linux X终端以便Emacs可以访问256种颜色？

Question

当我emacs -nw在X终端窗口中运行时,我要求M-x list-colors-display提供一个微不足道的调色板:

black                                                     
red    
green  
yellow 
blue   
magenta
cyan   
white  

我被告知有可能获得265种颜色.将TERM环境变量设置为xterm-256color不执行任务.什么

Answer 1

据此，ncurses-term除了设置为 之外，TERM您还需要库xterm-256color。

好的，这还有一些其他的事情可以尝试，例如：

The xterm in Ubuntu Edgy does not advertise 256 color support by
default.  To fix this you need to install a 256 color terminfo entry,
and tell xterm to use it:

    apt-get install ncurses-term
    echo XTerm.termName: xterm-256color \
      >>~/.Xdefaults
    xrdb -merge ~/.Xdefaults

和 ：

So you need a file term/screen-256color.el in your load-path.  Emacs
22 expects it to contain a terminal-init-screen defun.  Emacs 21
expects it to contain a bunch of top-level forms.  Here's what I use:

    ;;; This is for GNU Emacs 22
    (defun terminal-init-screen ()
      "Terminal initialization function for screen."
      ;; Use the xterm color initialization code.
      (load "term/xterm")
      (xterm-register-default-colors)
      (tty-set-up-initial-frame-faces))

    ;;; This is for GNU Emacs 21
    (if (= 21 emacs-major-version)
        (load "term/xterm-256color"))

For Emacs 21, you also need to install the xterm-256color.el file from
