go-logger
log for golang on logger,support level and persional 在原生logger包的基础上改变而来 支持级别控制 默认基本为INFO，高级别自动显示低级别的日志，但是低级别的日志是不显示高级别的日志 修改日志在没有另外实例化的情况下，是影响设置后的代码显示，建议只在项目开始处进行配置
自带行号和日志发生时的文件
#Default the info is default info if you didn`t set . you could set the level as :
const (
LvlCrit int32= iota
LvlError
LvlWarn
LvlInfo
LvlDebug
LvlTrace
)
#example
type data struct {
A int
}
func TestLogger(t *testing.T){
Error( "test" ,"why" , data{11})
Warn( "warn" ,"why" , data{11})
Info( "info" ,"why" , data{11})
SetLevel(LvlDebug)
Debug( "debug" ,"why" , data{11})
Trace( "trace" ,"why" , data{11})
log := New( os.Stderr , Lshortfile | LstdFlags , "test ")
log.Error( "test" ,"why" , data{11})
log.Warn( "warn" ,"why" , data{11})
log.Info( "info" ,"why" , data{11})
log.Debug( "debug" ,"why" , data{11})
log.Trace( "trace" ,"why" , data{11})
log.Debug( "debug" ,"why" , data{11})
log.Trace( "trace" ,"why" , data{11})
}

test info 2018/09/17 15:28:25 logger_test.go:22: info [why {11}]
test debug 2018/09/17 15:28:25 logger_test.go:23: debug [why {11}]
test debug 2018/09/17 15:28:25 logger_test.go:25: debug [why {11}]
as you see that didnt print debug and trace if you didnt set the level as trace
of cause that didn`t print trace if you set level as debug
