# Simple Log
A very simple log system(golang).
## Install
```bash
go get github.com/lion187chen/simplelog
```
## Demo
```go
package main
import (
"time"
"github.com/lion187chen/simplelog"
)
func CreateLog(file string, LogLevel simplelog.LogLevel) *simplelog.SimpleLog {
switch file {
case "":
return new(simplelog.SimpleLog).InitStd(LogLevel, simplelog.Ltime|simplelog.Lfile|simplelog.Llevel)
default:
return new(simplelog.SimpleLog).InitRotating(file, 1024*10, 10, LogLevel)
}
}
func main() {
log := CreateLog("./log/MS.log", simplelog.LevelInfo)
for i := 0; i < 10000000; i++ {
log.Trace("hello world")
log.Debug("hello world")
log.Info("hello world")
log.Warn("hello world")
log.Error("hello world")
log.Fatal("hello world")
time.Sleep(8 * time.Millisecond)
}
}
```
