Generic leveled logger interface

Usage

Checkout example for details.

go get -u clevergo.tech/log

Standard Logger

StdLogger wraps Go standard logger log.Logger.

import (
    stdlog "log"

    "clevergo.tech/log"
)

var logger log.Logger = log.New(os.Stderr, "", stdlog.LstdFlags)

Logrus

import (
    "clevergo.tech/log"
    "github.com/sirupsen/logrus"
)

var logger log.Logger = logrus.New()

Zap

import (
    "clevergo.tech/log"
    "go.uber.org/zap"
)

var logger log.Logger = zap.NewExample().Sugar()
