如何在ncurses中使用8种以上的颜色? [英] How do i use more than 8 colors in ncurses?

问题描述

我刚刚开始在Linux上使用ncurses.我想使用8种以上的颜色，但是只有8种可用.

I just started to use ncurses on Linux. I wanted to use more than 8 colors, but there were only 8 available.

如何使用更多颜色，或者通过给它们命名来创建自己的颜色并设置其RGB值?

How can I use more colors, or create my own by giving them a names, and set their RGB values?

我尝试使用init_color编辑一种颜色，但这只会替换当前8种颜色中的一种，而不是创建新的颜色.

I tried editing a color with init_color, but that will simply replace one of the current 8 instead of creating new ones.

注意:全局var COLORS的值为256，所以我相信我最多可以使用256种不同的颜色.

Note: the value of the global var COLORS is 256, so I believe I can use up to 256 different colors.

推荐答案

如果您的终端支持，则应该选择(或自定义)具有8种以上颜色的终端描述.实际上，有很多可用的现有终端描述:大多数是为特定终端(或终端仿真器)定制的.

If your terminal supports it, you should choose (or customize) a terminal description which has more than 8 colors. As it is, there are a lot of existing terminal descriptions which could be used: most are customized for particular terminals (or terminal emulators).

如果您的终端支持，相应的描述将具有功能initc.这由库调用init_color使用.在 xterm-256color 条目中，例如:

If your terminal supports it, the corresponding description would have the capability initc. That is used by the library call init_color. The xterm-256color entry has this for instance:

initc=\E]4;%p1%d;rgb\:%p2%{255}%*%{1000}%/%2.2X/%p3%{255}%*%{1000}%/%2.2X/%p4%{255}%*%{1000}%/%2.2X\E\\,

告诉库如何将三个参数转换为转义序列.终端条目由可重复使用的部分构成，例如 xterm + 256color ，因为某些终端缺少您感兴趣的功能.对于这些终端，请 xterm + 256setaf 是合适的.

which tells the library how to translate the three parameters into an escape sequence. The terminal entries are built up from reusable parts such as xterm+256color, because some terminals lack the feature you are interested in. For those, xterm+256setaf is appropriate.

• 为什么只有16种(或256种)颜色?
