Logger.h //////////////////////////////////////////////////////////////////////////////////////////////// Description.

Contains basic functionality for categorized logging to console. The logging statements will either print to stdout or to stderr depending on the category of the message.

Logging should be done through the different macros, NOT through the log_internal function!

All messages will be following the specified format: <category>: <file>: <function>: <line_number>: user specified message.

Example: [INFO ]: main.cpp : main : 7: User specified message

The logs must be written with printf syntax, which can be found here: http://en.cppreference.com/w/cpp/io/c/fprintf

note, you must use .c_str() or .data() when sending a std::string to "%s".

Example of usage: #include <string> #include "logger.h"

int main() { std::string str = "hey"; LOG_DEBUG("Logging debug: %s yas", str.c_str()); return 0; }

Will return something like: [DEBUG]: main.cpp : main : 7: Logging debug: hey yas

#define LOG_DEBUG	(	fmt,
		...
	)	log_internal(stdout, "DEBUG", LOG_COLOR_FG_CYAN, __FILE__, __func__, __LINE__, fmt, ##__VA_ARGS__);

Prints debug information to stdout.

Use this for debug related information, can be turned off by defining LOG_NO_DEBUG before including logger.h

#define LOG_ERROR	(	fmt,
		...
	)

Value:

{                                                                                                       \
    log_internal(stderr, "ERROR", LOG_COLOR_FG_RED, __FILE__, __func__, __LINE__, fmt, ##__VA_ARGS__);  \
    LOG_TERMINAL_PAUSE;                                                                                 \
    std::exit(EXIT_FAILURE);                                                                            \
}

Prints the specified error to stderr and terminates the program.

This error is supposed to be used for unrecoverable errors.

#define LOG_INFO	(	fmt,
		...
	)	log_internal(stdout, "INFO", LOG_COLOR_FG_WHITE, __FILE__, __func__, __LINE__, fmt, ##__VA_ARGS__);

Prints regular info to stdout.

#define LOG_TERMINAL_PAUSE

Convenience macro for letting the console "hang" on windows systems.

#define LOG_WARN	(	fmt,
		...
	)	log_internal(stderr, "WARN", LOG_COLOR_FG_YELLOW, __FILE__, __func__, __LINE__, fmt, ##__VA_ARGS__);

Prints the specified warning to stderr. Use for non breaking situations.

Function Documentation

void log_internal	(	FILE *	file,
		const char *	type,
		const char *	color,
		const char *	filepath,
		const char *	func,

		const char *	fmt,
			...
	)

Actual function which is called by log macros.

Note: ATTENTION! Do not use this function! You are supposed to use the logger macros!
