C language logging library logging
brief
Logging is a lightweight and easy-to-use C language log library that supports log level, log format, log output, log files, and other functions.
function
- Support log levels: DEBUG, INFO, Warning, ERROR, FATAL
- Support log formats: timestamp, log level, log content
- Support log output: console, file
- Support log files: automatic creation, automatic scrolling, log segmentation
install
- Conan
conan create .
- cmake
git clone https://github.com/WangZhongDian/logging.git
cd logging
cmake build -B build . && cd build && cmake --build .
cmake --install .
usage
console log
#include "logging.h"
int main() {
Logger *logger = newDefaultLogger("testLogger", LOG_DEBUG);
log_info("This is an info message");
log_error("This is an error message%s", "123");
log_fatal("This is an fatal message");
log_debug("This is a debug message");
log_warning("This is a warning message%s", "123");
destroyDefaultLogger();
return 0;
}
file log
#include "logging.h"
#include "logging/logging-handler.h"
int main() {
Logger *logger = newDefaultLogger("testLogger", LOG_DEBUG);
logger->addHandler(loggingHandlerFile("test1", 1024*1024));
log_info("This is an info message");
log_error("This is an error message%s", "123");
log_fatal("This is an fatal message");
log_debug("This is a debug message");
log_warning("This is a warning message%s", "123");
destroyDefaultLogger();
return 0;
}
Logging filter
Support adding custom filters, currently with built-in substring filters The function of an filter is to redirect filtered logs to the filter's dedicated processor
example
Redirects filtered logs to a dedicated file processor
#include "logging.h"
#include <stdio.h>
int main() {
Logger *logger = newDefaultLogger("testLogger", LOG_DEBUG);
log_info("This is an info message");
log_error("This is an error message%s", "123");
log_fatal("This is an fatal message");
log_debug("This is a debug message");
log_warning("This is a warning message%s", "123");
char *test1[] = {"123", "tt", NULL};
log_filter *tint = loggingFilterSubStr(
test1,
LOG_DEBUG,
loggingHandlerFile("test_interceptor", 1024 * 1024),
true);
logger->addFilter(tint);
printf("\n");
printf("filter added\n");
printf("\n");
log_info("This is an info message");
log_error("This is an error message%s", "123");
log_fatal("This is an fatal message");
log_debug("This is a debug message");
log_warning("This is a warning message%s", "123");
destroyDefaultLogger();
return 0;
}
Multiple substring filters
#include "logging.h"
#include <stdbool.h>
#include <stdio.h>
#include <time.h>
int main() {
Logger *logger = newDefaultLogger("testLogger", LOG_DEBUG);
log_info("This is an info message");
log_error("This is an error message%s", "123");
log_fatal("This is an fatal message");
log_debug("This is a debug message");
log_warning("This is a warning message%s", "123");
char *test1[] = {"This",NULL};
log_filter *tint = loggingFilterSubStr(
test1,
LOG_DEBUG,
loggingHandlerFile("test_interceptor", 1024 * 1024),
false);
logger->addFilter(tint);
char *test2[] = {"123",NULL};
log_filter *tint1 = loggingFilterSubStr(
test2,
LOG_DEBUG,
loggingHandlerFile("test_interceptor1", 1024 * 1024),
true);
logger->addFilter(tint1);
printf("\n");
printf("filter added\n");
printf("\n");
log_info("This is an info message");
log_error("This is an error message%s", "123");
log_fatal("This is an fatal message");
log_debug("This is a debug message");
log_warning("This is a warning message%s", "123");
destroyDefaultLogger();
return 0;
}
