Color

[matjaz87]

How to give colors to levels :).

[rdpoor]

If you look at the README.md:

void my_console_logger(ulog_level_t severity, const char *msg) {
     printf("%s [%s]: %s\n",
         get_timestamp(),    // user defined function
         ulog_level_name(severity),
         msg);
}

.... you'll see that each logging function receives the message as well as the logging level. You can use the logging level to choose a color, and then use the ANSI terminal commands to send the escape sequence to set that color.

Here's a stack overflow posting that summarizes the escape sequences for you:

Thank you :)
I do it like that:

#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"

void my_console_logger(ulog_level_t severity, char *msg) {
	switch(severity)
	{
		case ULOG_ERROR_LEVEL:
			printf("[%d] %s%s%s: %s\r\n",
				 HAL_GetTick(),
				 KRED,
				 ulog_level_name(severity),
		                 KNRM,
				 msg);
			break;

		case ULOG_WARNING_LEVEL:
			printf("[%d] %s%s%s: %s\r\n",
				 HAL_GetTick(),
				 KYEL,
				 ulog_level_name(severity),
		                 KNRM,
				 msg);
			break;

		case ULOG_INFO_LEVEL:
			printf("[%d] %s%s%s: %s\r\n",
				 HAL_GetTick(),
				 KGRN,
				 ulog_level_name(severity),
		                 KNRM,
				 msg);
			break;		
		
		default:
			printf("[%d] %s: %s\r\n",
				 HAL_GetTick(),    
				 ulog_level_name(severity),
				 msg);
			break;
	}

}
