easylogger使用

EasyLogger简单使用

移植

1. 下载源码

   git clone git@github.com:armink/EasyLogger.git
   

2. 将c文件和头文件复制到项目中，并包含相应的头文件路径

   

3. 修改elog_cfg.h（不需要的直接注释）

   #ifndef _ELOG_CFG_H_
   #define _ELOG_CFG_H_
   /*---------------------------------------------------------------------------*/
   /* enable log output. */
   #define ELOG_OUTPUT_ENABLE
   /* setting static output log level. range: from ELOG_LVL_ASSERT to ELOG_LVL_VERBOSE */
   #define ELOG_OUTPUT_LVL                          ELOG_LVL_VERBOSE
   /* enable assert check */
   #define ELOG_ASSERT_ENABLE
   /* buffer size for every line's log */
   #define ELOG_LINE_BUF_SIZE                       256
   /* output line number max length */
   #define ELOG_LINE_NUM_MAX_LEN                    5
   /* output filter's tag max length */
   #define ELOG_FILTER_TAG_MAX_LEN                  30
   /* output filter's keyword max length */
   #define ELOG_FILTER_KW_MAX_LEN                   16
   /* output filter's tag level max num */
   #define ELOG_FILTER_TAG_LVL_MAX_NUM              5
   /* output newline sign */
   #define ELOG_NEWLINE_SIGN                        "\n"
   /*---------------------------------------------------------------------------*/
   /* enable log color */
   #define ELOG_COLOR_ENABLE
   /* change the some level logs to not default color if you want */
   #define ELOG_COLOR_ASSERT                        (F_MAGENTA B_NULL S_NORMAL)
   #define ELOG_COLOR_ERROR                         (F_RED B_NULL S_BLINK)
   #define ELOG_COLOR_WARN                          (F_YELLOW B_NULL S_NORMAL)
   #define ELOG_COLOR_INFO                          (F_CYAN B_NULL S_NORMAL)
   #define ELOG_COLOR_DEBUG                         (F_GREEN B_NULL S_NORMAL)
   #define ELOG_COLOR_VERBOSE                       (F_BLUE B_NULL S_NORMAL)
   /*---------------------------------------------------------------------------*/
   ///* enable asynchronous output mode */
   //#define ELOG_ASYNC_OUTPUT_ENABLE
   ///* the highest output level for async mode, other level will sync output */
   //#define ELOG_ASYNC_OUTPUT_LVL                    ELOG_LVL_ASSERT
   ///* buffer size for asynchronous output mode */
   //#define ELOG_ASYNC_OUTPUT_BUF_SIZE               (ELOG_LINE_BUF_SIZE * 10)
   ///* each asynchronous output's log which must end with newline sign */
   //#define ELOG_ASYNC_LINE_OUTPUT
   ///* asynchronous output mode using POSIX pthread implementation */
   //#define ELOG_ASYNC_OUTPUT_USING_PTHREAD
   ///*---------------------------------------------------------------------------*/
   ///* enable buffered output mode */
   //#define ELOG_BUF_OUTPUT_ENABLE
   ///* buffer size for buffered output mode */
   //#define ELOG_BUF_OUTPUT_BUF_SIZE                 (ELOG_LINE_BUF_SIZE * 10)
   

4. 修改elog_port.c

   #include "main.h"			//hal_gettick()声明
   #include "printf.h"			//printf()声明
   uint8_t timestamp_s[10];	//时间戳字符串
   
   //输出接口
   void elog_port_output(const char *log, size_t size) {
       /* add your code here */
       printf("%.*s",size,log);
   }
   //输出上锁
   void elog_port_output_lock(void) {
       
       /* add your code here */
       //关闭全局中断(裸机)
   	__set_PRIMASK(1);
   }
   //输出关锁
   void elog_port_output_lock(void) {
       
       /* add your code here */
       //关闭全局中断(裸机)
   	__set_PRIMASK(1);
   }
   //获取时间戳
   const char *elog_port_get_time(void) {
       
       /* add your code here */
   	snprintf((char *)timestamp_s,sizeof(timestamp_s),"%09lu",HAL_GetTick());//获取tick计数值作为时间戳，09lu:32位无符号整形(字符串为9位)
   	return (char *)timestamp_s;
   }
   
   //其他接口：获取进程号，线程号等根据需要添加
   

5. 初始化

   elog_init();								//elog初始化
   elog_set_text_color_enabled(true);			//使能文本颜色输出
   elog_set_fmt(ELOG_LVL_ASSERT, ELOG_FMT_ALL);//设置输出格式
   elog_set_fmt(ELOG_LVL_ERROR, ELOG_FMT_LVL | ELOG_FMT_TAG | ELOG_FMT_TIME);
   elog_set_fmt(ELOG_LVL_WARN, ELOG_FMT_LVL | ELOG_FMT_TAG | ELOG_FMT_TIME);
   elog_set_fmt(ELOG_LVL_INFO, ELOG_FMT_LVL | ELOG_FMT_TAG | ELOG_FMT_TIME);
   elog_set_fmt(ELOG_LVL_DEBUG, ELOG_FMT_ALL & ~(ELOG_FMT_FUNC | ELOG_FMT_T_INFO | ELOG_FMT_P_INFO));
   elog_set_fmt(ELOG_LVL_VERBOSE, ELOG_FMT_ALL & ~(ELOG_FMT_FUNC | ELOG_FMT_T_INFO | ELOG_FMT_P_INFO));
   elog_start();								//elog启动
   

运行效果

1. 等级
2. 标签
3. 时间戳
4. 进程
5. 线程
6. 目录
7. 行号
8. 函数名
9. 输出

注意事项

当引入第三方printf库作为elog的输出时，要把该库的头文件包含到elog_cfg.h
