#### 介绍
开箱即用的zap logger，基于tony bai的文章

#### 软件架构
软件架构说明


#### 安装教程

需要使用时，import路径是：gitee.com/alemond/log

安装执行：

```shell
go get gitee.com/alemond/log
```

#### 使用说明

1.  log.Zap*默认使用Logger: std；std默认为输出到stderr，debuglevel，console fmt，需要手动输入msg与filed
2.  log.*默认使用Logger: std sugar，与上述配置相同，提供interface输入

写入文档：

```go
file, err := os.OpenFile("./demo1.log", os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0644)
if err != nil {
    panic(err)
}

logger := log.New(file, log.InfoLevel, log.JsonFmt)	
// logger := log.New(file, log.InfoLevel, log.JsonFmt, log.AddCallerSkip(1))

log.ResetDefault(logger)
log.Info("demo")
```

多文件写入：

```go
 file1, err := os.OpenFile("./access.log", os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0644)
 if err != nil {
     panic(err)
 }
 file2, err := os.OpenFile("./error.log", os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0644)
 if err != nil {
     panic(err)
 }
 
 var tops = []log.TeeOption{
     {
         W: file1,
         Lef: func(lvl log.Level) bool {
             return lvl <= log.InfoLevel
         },
     },
     {
         W: file2,
         Lef: func(lvl log.Level) bool {
             return lvl > log.InfoLevel
         },
     },
 }
 
 logger := log.NewTee(tops)
 log.ResetDefault(logger)
```

文件rotate

```go
    var tops = []log.TeeOption{
        {
            Filename: "access.log",
            Ropt: log.RotateOptions{
                MaxSize:    1,
                MaxAge:     1,
                MaxBackups: 3,
                Compress:   true,
            },
            Lef: func(lvl log.Level) bool {
                return lvl <= log.InfoLevel
            },
        },
        {
            Filename: "error.log",
            Ropt: log.RotateOptions{
                MaxSize:    1,
                MaxAge:     1,
                MaxBackups: 3,
                Compress:   true,
            },
            Lef: func(lvl log.Level) bool {
                return lvl > log.InfoLevel
            },
        },
    }

    logger := log.NewTeeWithRotate(tops)
    log.ResetDefault(logger)
```
