Emacs的Python模式语法高亮 [英] Emacs Python-mode syntax highlighting

问题描述

我在Ubuntu 10.04桌面计算机上安装了GNU Emacs 23（包 emacs23 ），并且包 emacs23-nox 安装在Ubuntu 10.04无头服务器上（未安装X）。两个安装都具有相同的〜/ .emacs 文件。我在两台电脑上运行了 -nw 的Emacs。我没有在任一机器上安装 python-mode ，因为我的理解是这包含在Emacs 23中。

I have GNU Emacs 23 (package emacs23) installed on an Ubuntu 10.04 desktop machine and package emacs23-nox installed on an Ubuntu 10.04 headless server (no X installed). Both installations have the same ~/.emacs file. I run Emacs with -nw on both computers. I don't have python-mode installed on either machine as my understanding is that this is included in Emacs 23.

在台式机上，Python中的注释（以＃开头）以红色突出显示。在服务器上，注释以纯文本形式显示，如所有其他未突出显示的文本。关于为什么在服务器（ nox ）安装时没有正确突出评论的建议？

On the desktop machine, comments in Python (starting with #) are highlighted in red. On the server, comments appear in plain white text like all other non-highlighted text. Any suggestions as to why comments are not being highlighted correctly on the server (nox) installation?

更新：这似乎是与终端有关的问题。从终止者通过屏幕替换 ssh 进入服务器机器 byobu 。如果我使用 TERM =xterm-256coloremacs 在服务器上运行emacs，那么注释将突出显示，但所有其他颜色看起来都很奇怪。

Update: This appears to be a terminal-related issue. I ssh into the server machine from terminator via the screen replacement byobu. If I run emacs on the server with TERM="xterm-256color" emacs, then comments are highlighted, but all the other colours look very strange.

更新：添加export TERM =xterm-256color已解决现在的语法高亮现在有非常奇怪的颜色：紫色淡紫色和浅棕色。我现在的绿色线条亮点条现在是淡淡的淡黄色/绿色。注释以红色突出显示：）

Update: Adding `export TERM="xterm-256color" "solved" this. The syntax highlighting now has very strange colours though: purples lilacs and light browns. My green current line highlight bar is now a light pale yellow/green. Comments are highlighted in red though :)

更新：已解决。设置 TERM =xterm-color code>产生正确颜色，包括注释。服务器默认为 TERM 的值screen-bce，而不突出显示注释。

Update: Solved. Setting TERM="xterm-color" produces "proper" colors, including highlighting of comments. The server was defaulting to a value of "screen-bce" for TERM which was not highlighting comments.

Update：Unsolved。 byobu 为各种功能键提供了键盘绑定，可以轻松创建新的屏幕会话并在它们之间切换。当 TERM 设置为 xterm-color 时，这些功能键不再有效。所以我想我只需要在Emacs的Python代码中看到不高兴的评论。

Update: Unsolved. byobu provides keybindings for various function keys to easily create new screen sessions and switch between them. When TERM is set to xterm-color, these function keys no longer work. So I guess I'll just have to be happy with unhighlighted comments in Python code in Emacs.

推荐答案

对于我运行 emacs -nw 从 byobu 与 TERM = xterm 产生正确语法高亮的颜色（python和bash中的注释都不仅仅是＃），功能键也可以工作。注意我设置 TERM 作为运行emacs的别名的一部分，而不是一般在 .bashrc 中设置：

For me running emacs -nw from inside byobu with TERM=xterm produced the correct colours for syntax highlighting (the comments in python and bash are all red not just the #) and the function keys work. Note I set TERM as part of an alias for running emacs rather than setting it generally in .bashrc:

alias emacs ='TERM = xterm; emacs -nw'

另请参阅这篇文章：终端emacs颜色只能使用TERM = xterm-256color
