# 使用 Define 宏自定义 Log 系统
## C/C++ 语言简易版本
注意 "] " 前后要有空格，否则编译错误。
```cpp
#include <stdio.h>
#define LOG_DBG 0
#define LOG_INF 1
#define LOG_WAR 2
#define LOG_ERR 3
#define LOG_NOP 4
#define LOG_LEVEL LOG_DBG
#if (LOG_LEVEL<=LOG_DBG)
#define DLog(tag, ...) printf("[DBG|"#tag "] " __VA_ARGS__)
#else // !(LOG_LEVEL<LOG_DBG)
#define DLog(tag, ...)
#endif // (LOG_LEVEL<LOG_DBG)
#if (LOG_LEVEL<=LOG_INF)
#define ILog(tag, ...) printf("[INF|"#tag "] " __VA_ARGS__)
#else // !(LOG_LEVEL<LOG_INF)
#define ILog(tag, ...)
#endif // (LOG_LEVEL<LOG_INF)
#if (LOG_LEVEL<=LOG_WAR)
#define WLog(tag, ...) printf("[WAR|"#tag "] " __VA_ARGS__)
#else // !(LOG_LEVEL<LOG_WAR)
#define WLog(tag, ...)
#endif // (LOG_LEVEL<LOG_WAR)
#if (LOG_LEVEL<=LOG_ERR)
#define ELog(tag, ...) printf("[ERR|"#tag "] " __VA_ARGS__)
#else // !(LOG_LEVEL<LOG_WAR)
#define ELog(tag, ...)
#endif // (LOG_LEVEL<LOG_WAR)
```
## C++ 带类和函数的扩展版
```cpp
#include <stdio.h>
#define LOG_DBG 0
#define LOG_INF 1
#define LOG_WAR 2
#define LOG_ERR 3
#define LOG_NOP 4
#define LOG_LEVEL LOG_DBG
#if (LOG_LEVEL<=LOG_DBG)
#define DLog0(fmt) printf("[HDBG|%s]" fmt, __PRETTY_FUNCTION__)
#define DLog(fmt, ...) printf("[HDBG|%s]" fmt, __PRETTY_FUNCTION__, __VA_ARGS__)
#else // !(LOG_LEVEL<LOG_DBG)
#define DLog0(fmt)
#define DLog(fmt, ...)
#endif // (LOG_LEVEL<LOG_DBG)
#if (LOG_LEVEL<=LOG_INF)
#define ILog0(fmt) printf("[HINF|%s]" fmt, __PRETTY_FUNCTION__)
#define ILog(fmt, ...) printf("[HINF|%s]" fmt, __PRETTY_FUNCTION__, __VA_ARGS__)
#else // !(LOG_LEVEL<LOG_INF)
#define ILog0(fmt)
#define ILog(fmt, ...)
#endif // (LOG_LEVEL<LOG_INF)
#if (LOG_LEVEL<=LOG_WAR)
#define WLog0(fmt) printf("[HWAR|%s]" fmt, __PRETTY_FUNCTION__)
#define WLog(fmt, ...) printf("[HWAR|%s]" fmt, __PRETTY_FUNCTION__, __VA_ARGS__)
#else // !(LOG_LEVEL<LOG_WAR)
#define WLog0(fmt)
#define WLog(fmt, ...)
#endif // (LOG_LEVEL<LOG_WAR)
#if (LOG_LEVEL<=LOG_ERR)
#define ELog0(fmt) printf("[HERR|%s]" fmt, __PRETTY_FUNCTION__)
#define ELog(fmt, ...) printf("[HERR|%s]" fmt, __PRETTY_FUNCTION__, __VA_ARGS__)
#else // !(LOG_LEVEL<LOG_WAR)
#define ELog0(fmt)
#define ELog(fmt, ...)
#endif // (LOG_LEVEL<LOG_WAR)
