C語言輸出顏色

命令後界面輸出顏色

嵌入式終端界面輸出日誌時，爲了區分輸出的有用信息、錯誤信息，可以給不同級別的輸出加上不同的顏色，以方便查看。
下面是顏色的定義：

//顏色宏定義
#define NONE         "\033[m"
#define RED          "\033[0;32;31m"
#define LIGHT_RED    "\033[1;31m"
#define GREEN        "\033[0;32;32m"
#define LIGHT_GREEN  "\033[1;32m"
#define BLUE         "\033[0;32;34m"
#define LIGHT_BLUE   "\033[1;34m"
#define DARY_GRAY    "\033[1;30m"
#define CYAN         "\033[0;36m"
#define LIGHT_CYAN   "\033[1;36m"
#define PURPLE       "\033[0;35m"
#define LIGHT_PURPLE "\033[1;35m"
#define BROWN        "\033[0;33m"
#define YELLOW       "\033[1;33m"
#define LIGHT_GRAY   "\033[0;37m"
#define WHITE        "\033[1;37m"

使用方法

如下:

printf(YELLOW"this print msg is yellow!\n"NONE);

這樣打印出來的字符串: “this print msg is yellow!” 就是黃色的。
顏色值放在打印內容開始的雙引號前面，結束時再雙引號後面加上NONE，用於結束顏色作用域.

完成測試代碼

#include <stdio.h>

//顏色宏定義
#define NONE         "\033[m"
#define RED          "\033[0;32;31m"
#define LIGHT_RED    "\033[1;31m"
#define GREEN        "\033[0;32;32m"
#define LIGHT_GREEN  "\033[1;32m"
#define BLUE         "\033[0;32;34m"
#define LIGHT_BLUE   "\033[1;34m"
#define DARY_GRAY    "\033[1;30m"
#define CYAN         "\033[0;36m"
#define LIGHT_CYAN   "\033[1;36m"
#define PURPLE       "\033[0;35m"
#define LIGHT_PURPLE "\033[1;35m"
#define BROWN        "\033[0;33m"
#define YELLOW       "\033[1;33m"
#define LIGHT_GRAY   "\033[0;37m"
#define WHITE        "\033[1;37m"


int main()
{
	printf(RED"紅色****************************\n"NONE);
	printf(LIGHT_RED"亮紅色**************************\n"NONE);
	printf(GREEN"綠色****************************\n"NONE);
	printf(LIGHT_GREEN"亮綠色****************************\n"NONE);

	printf(BLUE"藍色******************************\n"NONE);
	printf(LIGHT_BLUE"亮藍色****************************\n"NONE);

	printf(DARY_GRAY"灰色******************************\n"NONE);
	printf(CYAN"青色*****************************\n"NONE);
	printf(LIGHT_CYAN"亮青色****************************\n"NONE);
	
	printf(PURPLE"紫色*****************************\n"NONE);
	printf(LIGHT_PURPLE"亮紫色****************************\n"NONE);

	printf(BROWN"棕色*****************************\n"NONE);
	printf(YELLOW"黃色****************************\n"NONE);
	printf(LIGHT_GRAY"亮灰色*****************************\n"NONE);
	printf(WHITE"白色****************************\n"NONE);

	return 0;
