# C语言日志库logging [English](README.en.md) ## 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 ```shell git clone https://github.com/WangZhongDian/logging.git cd logging conan create . ``` 在你的项目的conanfile.txt中添加 ```txt [requires] logging/0.5.0 ``` ```shell conan install . --build=missing ``` ### cmake安装使用 ```shell 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 ```c #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 ```c #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 ```c #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 ```c #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; } ```
