Functions

func Context

func Context(ctx context.Context, opts ...interface{}) context.Context

func CtxDebug

func CtxDebug(ctx context.Context, args ...interface{})

CtxDebug uses fmt.Sprint to construct and log a message. The metaInfo in Context will be appended to message as fields.

func CtxDebugf

func CtxDebugf(ctx context.Context, fmt string, args ...interface{})

CtxDebugf uses fmt.Sprintf to log a templated message. The metaInfo in Context will be appended to message as fields.

func CtxDebugw

func CtxDebugw(ctx context.Context, msg string, kvs ...interface{})

CtxDebugw logs a message with some additional context. The variadic key-value pairs are treated as they are in With. The metaInfo in Context will be appended to message as fields.

When debug-level logging is disabled, this is much faster than

s.With(keysAndValues).CtxDebug(msg)

CtxWarnw logs a message with some additional context. The variadic key-value pairs are treated as they are in With. The metaInfo in Context will be appended to message as fields.

func Debug

func Debug(args ...interface{})

Debug uses fmt.Sprint to construct and log a message.

func Debugf

func Debugf(fmt string, args ...interface{})

func Debugw

func Debugw(msg string, kvs ...interface{})

Debugw logs a message with some additional context. The variadic key-value pairs are treated as they are in With.

When debug-level logging is disabled, this is much faster than

s.With(keysAndValues).Debug(msg)

func Error

func Error(args ...interface{})

Error uses fmt.Sprint to construct and log a message.

func Errorf

func Errorf(fmt string, args ...interface{})

Errorf uses fmt.Sprintf to log a templated message.

func Errorw

func Errorw(msg string, kvs ...interface{})

func StandardizePath

func StandardizePath(filePath, serviceName string) string

StandardizePath is meant to decorate given file path by nodeIP/localIP/serviceName so that the returned path is consistent and unified throughout all services under node-real org The path after decoration will be `<file_path>/<node_ip>/<local_ip>/<service_name>.log`

func Stop

func Stop()

Stop flushes any buffered log entries, then stops writer. This method should be called when program stopping. For example,

func main() {
  defer log.Stop()

  log.Init(lvl, path)
}

Types

type AsyncFileWriter

type AsyncFileWriter struct {
	// contains filtered or unexported fields
}

func NewAsyncFileWriter

func NewAsyncFileWriter(filePath string, bufSize int64) *AsyncFileWriter

func (*AsyncFileWriter) Start

func (w *AsyncFileWriter) Start() error

func (*AsyncFileWriter) Stop

func (w *AsyncFileWriter) Stop() error

func (*AsyncFileWriter) Sync

func (w *AsyncFileWriter) Sync() error

func (*AsyncFileWriter) SyncWrite

func (w *AsyncFileWriter) SyncWrite(msg []byte)

func (*AsyncFileWriter) Write

func (w *AsyncFileWriter) Write(msg []byte) (n int, err error)

type AsyncWriter

type AsyncWriter types.AsyncWriter

AsyncWriter uses as log writer

func AddSync

func AddSync(w io.Writer) AsyncWriter

func NewMultiWriteSyncer

func NewMultiWriteSyncer(ws ...AsyncWriter) AsyncWriter

NewMultiWriteSyncer creates a WriteSyncer that duplicates its writes and sync calls, much like io.MultiWriter.

type HourTicker

type HourTicker struct {
	C <-chan time.Time
	// contains filtered or unexported fields
}

func NewHourTicker

func NewHourTicker() *HourTicker

func (*HourTicker) Stop

func (ht *HourTicker) Stop()

func (*HourTicker) Ticker

func (ht *HourTicker) Ticker() <-chan time.Time

type Level

type Level = types.Level

func ParseLevel

func ParseLevel(lvl string) (Level, error)

ParseLevel parses level from string.

type Logger

type Logger = types.Logger

func With

func With(kvs ...interface{}) Logger

With adds a variadic number of fields to the logging context. It accepts loosely-typed key-value pairs. When processing pairs, the first element of the pair is used as the field key and the second as the field value. Note that the keys in key-value pairs should be strings. For example,

 log.With(
   "hello", "world",
   "failure", errors.New("oh no"),
   "count", 42,
   "user", User{Name: "alice"},
   "err", errors.New("error")
)
