C语言日志库logging
简介
logging是一个轻量级的简单易用C语言日志库，支持日志级别、日志格式、日志输出、日志文件等功能。
功能
- 支持日志级别：DEBUG、INFO、WARN、ERROR、FATAL
- 支持日志格式：时间戳、日志级别、日志内容
- 支持日志输出：控制台、文件
- 支持日志文件：自动创建、自动滚动、日志分割
安装
conan安装使用
git clone https://github.com/WangZhongDian/logging.git
cd logging
conan create .
在你的项目的conanfile.txt中添加
[requires]
logging/0.5.0
conan install . --build=missing
cmake安装使用
git clone https://github.com/WangZhongDian/logging.git
cd logging
cmake build -B build . && cd build && cmake --build .
cmake --install .
使用方法
控制台日志
#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;
}
文件日志
#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;
}
日志过滤器
支持添加自定义的过滤器， 目前内置了子串过滤器
过滤器的作用:可以将过滤到的日志重定向到过滤器的专属处理器中
单个子串过滤器
将过滤到的日志重定向到专属处理器中
#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;
}
多个子串过滤器
#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;
