stdlib and colored output in C (8 answers)

Closed 5 years ago.

我开始撰写一份终端文本编辑,像UNIX的第一版编辑,如六版。我的唯一目标是有一段良好的时间,但我希望能够以色体显示案文,因此,我可以强调编辑源码。

我如何能够做到这一点? 是否有这方面的特别意向书IX,或者我是否必须使用纳米材料? (不是)

任何建议? 或许还有某些关于UNIXAP的教科书?

Answer 1

这是一项微小的C方案,说明你如何使用彩色编码:

#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;
}

这里是这样做的另一个途径。有些人更愿意这样做,因为守则是比较清洁的。没有<代码>%s和RESET以色标结束。

#include <stdio.h>

#define RED   "x1B[31m"
#define GRN   "x1B[32m"
#define YEL   "x1B[33m"
#define BLU   "x1B[34m"
#define MAG   "x1B[35m"
#define CYN   "x1B[36m"
#define WHT   "x1B[37m"
#define RESET "x1B[0m"

int main() {
  printf(RED "red
"     RESET);
  printf(GRN "green
"   RESET);
  printf(YEL "yellow
"  RESET);
  printf(BLU "blue
"    RESET);
  printf(MAG "magenta
" RESET);
  printf(CYN "cyan
"    RESET);
  printf(WHT "white
"   RESET);

  return 0;
}

该方案提供以下产出:

这样就很容易做这样的事情:

printf("This is " RED "red" RESET " and this is " BLU "blue" RESET "
");

该行产出如下:

Answer 4

或许希望ANSI彩色代码。大部分的Ednix终端站支持他们。
