终端emacs颜色只能使用TERM = xterm-256color [英] Terminal emacs colors only work with TERM=xterm-256color

问题描述

我发现终端emacs没有渲染正确的颜色，除非我明确设置TERM = xterm-256color。我使用gnome-terminal，从我的理解，TERM应设置为gnome-256color。同样地，我倾向于使用tmux，它建议不要使用screen-256color以外的任何TERM设置。不幸的是，这两个设置（在各自的上下文中 - gnome-terminal 或 tmux ）导致emacs有错误的颜色，而vim正确显示颜色。但是，如果我导出TERM = xterm-256color ，这些颜色在emacs中正常工作。

任何人都可以解释发生甚么或提供解决方案？

更新

这是我正在处理的： p>

我可以通过将以下内容添加到我的 init.el 中来获得正确的颜色：

 （defun terminal-init-gnome（）
gnome-terminal的终端初始化函数
 
 ;;这个是一个肮脏的黑客，我不小心绊倒：
 ;;初始化rxvt首先和_then_xterm似乎
 ;;使颜色工作...虽然我不知道为什么
（tty-run-terminal-initialization（selected-frame）rxvt）
 
（tty-run-terminal-initialization（selected-frame）xterm））
  

感觉真的真的错了啊。必须有一个逻辑的解释...

PS

我对terminfo知之甚少以及 $ TERM 在彩色终端行为过程中的确切作用。 如果总是使用 xterm-256color （即使 $ TERM 应该是code> gnome-256color 或 screen-256color ），我会一起去。

解决方案

也许我不了解某些东西，买你为什么不运行这样的emacs：

  TERM = xterm-256color emacs -nw 
  

Emacs有自己的TERM设置，你知道工作。您也可以在shell脚本中创建别名或将其包装。

I've found that terminal emacs does not render the correct colors unless I explicitly set TERM=xterm-256color. I use gnome-terminal, and from what I understand, TERM should be set to gnome-256color. Similarly, I tend to use tmux a lot, which advises against any TERM setting other than screen-256color. Unfortunately, both of those settings (within their respective context - gnome-terminal or tmux) result in emacs having wrong colors, whereas vim displays colors correctly. However, if I export TERM=xterm-256color, the colors work just fine in emacs.

Can anyone explain what's going on, or offer a solution?

Update

Here's what I'm dealing with:

I can get the colors to look correct in the terminal by adding the following to my init.el:

(defun terminal-init-gnome ()
  "Terminal initialization function for gnome-terminal."

  ;; This is a dirty hack that I accidentally stumbled across:
  ;;  initializing "rxvt" first and _then_ "xterm" seems
  ;;  to make the colors work... although I have no idea why.
  (tty-run-terminal-initialization (selected-frame) "rxvt")

  (tty-run-terminal-initialization (selected-frame) "xterm"))

This feels really, really wrong though. There has to be a logical explanation for this...

P.S.

I have very little knowledge of terminfo and the precise role that $TERM plays in the process of color terminal behavior. If it's safe to always use xterm-256color (even when $TERM "should" be gnome-256color or screen-256color), I'll go with that.

解决方案

Maybe I'm not understanding something, buy why don't you run emacs like this:

TERM=xterm-256color emacs -nw

This way Emacs has its own TERM setting that you know works. You can also make an alias or wrap this in shell-script.
