LINUX下printf输出字体的特效

时间:2021-06-03 15:02:03

在学习LINUX网络编程的时候我们做了一个聊天系统,当时为了界面更漂亮点,于是在百度上搜索了下关于printf()函数的用法,和大家分享下:

                          给printf的输出加上些特效比如颜色,可以让打印信息更鲜明,在debug的时候特别有用。

                        颜色:

                        #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"

                        比如:

                        printf("\033[31m ####----->> \033[32m" "hello\n"

                        "\033[m");

                        颜色分为背景色和字体色,30~39用来设置字体色,40~49设置背景:

                                背景色                        字体色

                                40: 黑                          30: 黑

                                41: 红                          31: 红

                                42: 绿                          32: 绿

                                43: 黄                          33: 黄

                                44: 蓝                          34: 蓝

                                45: 紫                          35: 紫

                                46: 深绿                      36: 深绿

                                47: 白色                      37: 白色

                        记得在打印完之后,把颜色恢复成NONE,不然再后面的打印都会跟着变色。

                        

                        另外,还可以加一些ANSI控制码。加颜色只是以下控制码中的一种:

                        \033[0m   关闭所有属性  

                        \033[1m   设置高亮度  

                        \033[4m   下划线  

                        \033[5m   闪烁  

                        \033[7m   反显  

                        \033[8m   消隐  

                        \033[30m   --   \033[37m   设置前景色  

                        \033[40m   --   \033[47m   设置背景色  

                        \033[nA   光标上移n行  

                        \033[nB   光标下移n行  

                        \033[nC   光标右移n行  

                        \033[nD   光标左移n行  

                        \033[y;xH设置光标位置  

                        \033[2J   清屏  

                        \033[K   清除从光标到行尾的内容  

                        \033[s   保存光标位置  

                        \033[u   恢复光标位置  

                        \033[?25l   隐藏光标  

                        \033[?25h   显示光标

                        printf( CYAN "current function is %s " GREEN " file line is %d\n" NONE,

                                    __FUNCTION__, __LINE__ );

                        fprintf(stderr, RED "current function is %s " BLUE " file line is %d\n" NONE,

                                    __FUNCTION__, __LINE__ );

                            return 0;
