Overview

Package zbark provides a wrapper to make zap.Loggers compatible with the bark.Logger interface and a wrapper to make bark.Loggers compatible with zap.Logger interface.

This package is only of interest to users of github.com/uber-common/bark.

Index

• func Barkify(l zap.Logger) bark.Logger
• func Debarkify(bl bark.Logger, lvl zap.Level) zap.Logger

Examples

• Barkify
• Debarkify

Functions

func Barkify

func Barkify(l zap.Logger) bark.Logger

Barkify wraps zap's JSON logger to make it compatible with the bark.Logger interface.

Example

package main

import (
	"github.com/uber-go/zap"
	"github.com/uber-go/zap/zbark"
)

func main() {
	zapLogger := zap.New(zap.NewJSONEncoder(
		zap.NoTime(), // discard timestamps in tests
	))

	// Wrap our structured logger to mimic bark.Logger.
	logger := zbark.Barkify(zapLogger)

	// The wrapped logger has bark's usual fluent API.
	logger.WithField("errors", 0).Infof("%v accepts arbitrary types.", "Bark")

}

Output:

{"level":"info","msg":"Bark accepts arbitrary types.","errors":0}

func Debarkify

func Debarkify(bl bark.Logger, lvl zap.Level) zap.Logger

Debarkify wraps bark.Logger to make it compatible with zap's JSON logger

Example

package main

import (
	"os"

	"github.com/uber-go/zap"
	"github.com/uber-go/zap/zbark"

	"github.com/Sirupsen/logrus"
	"github.com/uber-common/bark"
)

func main() {
	logrusLogger := logrus.New()
	logrusLogger.Out = os.Stdout
	logrusLogger.Formatter = &logrus.JSONFormatter{
		TimestampFormat: "lies",
	}
	barkLogger := bark.NewLoggerFromLogrus(logrusLogger).WithField("errors", 0)
	logger := zbark.Debarkify(barkLogger, zap.DebugLevel)

	// The wrapped logger has zap's actually fluent API.
	logger.Info("Zap accepts", zap.String("typed", "fields"))

}

Output:

{"errors":0,"level":"info","msg":"Zap accepts","time":"lies","typed":"fields"}
