# ylog
一个简单易用的 go 日志库。 [设计](http://yuancoder.com/ylog/)
## Features
- 支持日志级别: debug, info, warning, error
- 支持按日期旋转文件
- 支持 json 格式
- 支持自定义格式和输出
- 代码测试覆盖率 100%
- 线程安全的
- 超越 `sirupsen/logrus` 日志库的性能
## Install
```
go get -u github.com/lyuangg/ylog
```
## Usage
```go
// 基本使用
ylog.Info("hello")
ylog.Infof("hello %d", 1)
ylog.Debug("debug msg..")
ylog.Errorf("err msg: %s, %v", "err", "msg")
// json
ylog.SetFormatter(NewJsonFormatter())
// 自定义字段
ylog.With(Fields{
"requestid" : "123456",
"traceid" : 5555,
}).Info("hello ylog")
// 按日期旋转文件
outer := ylog.NewRotateFile("./testdata", "go-2006-01-02.log", 7)
ylog.SetOuter(outer)
// 设置日志级别
ylog.SetLevel(ylog.ParseLevel("debug"))
ylog.SetLevel(ylog.DebugLevel)
// new logger
newlog := ylog.New()
newlog.SetLevel(ylog.WarnLevel)
// 自定义格式和输出, 实现下面两个接口，调用 SetFormatter，SetOuter 方法
type (
Formatter interface {
Format(r Record) (string, error)
}
Outer interface {
Write(r Record) error
}
)
```
## Test
