UNIX 终端应用程序中的彩色文本 [英] Color text in terminal applications in UNIX

问题描述

我开始编写终端文本编辑器，类似于 UNIX 的第一个文本编辑器，例如 vi.我唯一的目标是玩得开心，但我希望能够以彩色显示文本，这样我就可以在编辑源代码时突出显示语法.

I started to write a terminal text editor, something like the first text editors for UNIX, such as vi. My only goal is to have a good time, but I want to be able to show text in color, so I can have syntax highlighting for editing source code.

我怎样才能做到这一点?是否有一些特殊的 POSIX API，或者我必须使用 ncurses?(我宁愿不要)

How can I achieve this? Is there some special POSIX API for this, or do I have to use ncurses? (I'd rather not)

有什么建议吗?也许有一些关于 UNIX API 的教科书?

Any advice? Maybe some textbooks on the UNIX API?

推荐答案

这是一个说明如何使用颜色代码的小 C 程序:

This is a little C program that illustrates how you could use color codes:

#include <stdio.h>

#define KNRM  "x1B[0m"
#define KRED  "x1B[31m"
#define KGRN  "x1B[32m"
#define KYEL  "x1B[33m"
#define KBLU  "x1B[34m"
#define KMAG  "x1B[35m"
#define KCYN  "x1B[36m"
#define KWHT  "x1B[37m"

int main()
{
    printf("%sred
", KRED);
    printf("%sgreen
", KGRN);
    printf("%syellow
", KYEL);
    printf("%sblue
", KBLU);
    printf("%smagenta
", KMAG);
    printf("%scyan
", KCYN);
    printf("%swhite
", KWHT);
    printf("%snormal
", KNRM);

    return 0;
}
