问题描述

我在写各种实用程序,以及我真的很喜欢彩色文本。没有什么特别的,只是使用转义序列。我创建了一个具有pprint(味精,颜色)函数的简单类。我知道了这里找到codeS 如果它是。你能做的最好是发送 sgr0 复位所有的属性设置为默认(未previous)。上的xterm, sgr0 Esc键[M 。如果要重置的颜色,并不会影响到其他属性,送其上的xterm是 Esc键[39;49米

这些codeS应该不难codeD。您应该使用的terminfo,termcap中或[n]的诅咒。

I'm writing various utilities, and I'm really liking colorized text. Nothing fancy, just using escape sequences. I've created a simple class that has a pprint(msg, color) function. I've got it working rather easily after finding the codes here.

The problem that I'm having is that I should be able to turn off the color after printing. For example, let's say a user runs my program that prints almost everything in the default terminal color, but there is an error, and I want to print the error in red. I prefix my error message with '\033[0;32m', and the message is in red. Unfortunately, all text is red until I change it. That's generally fine while my program is running because I know what color the messages should be. However, the color remains after my program ends. Basically, I'd like to read the current color when my program starts, and restore it when finished. The same way that scripts restore the pwd when exiting.

How do I read the current escape sequence?

System:Red Hat 5.xBashPython 2.3

Thanks for the help.

解决方案

I don't believe that's possible and it's unlikely to be portable if it were. The best you can do is send sgr0 which resets all attributes to default (not previous). On xterms, sgr0 is Esc[m. If you want to reset the colors and not affect other attributes, send op which on xterms is Esc[39;49m.

These codes should not be hardcoded. You should use terminfo, termcap or [n]curses.
