Zapr ⚡

A logr implementation using Zap.

Usage

import (
    "fmt"

    "go.uber.org/zap"
    "github.com/go-logr/logr"
    "github.com/directxman12/zapr"
)

func main() {
    var log logr.Logger

    zapLog, err := zap.NewDevelopment()
    if err != nil {
        panic(fmt.Sprintf("who watches the watchmen (%v)?", err))
    }
    log = zapr.NewLogger(zapLog)

    log.Info("Logr in action!", "the answer", 42)
}

Implementation Details

For the most part, concepts in Zap correspond directly with those in logr.

Unlike Zap, all fields must be in the form of suggared fields -- it's illegal to pass a strongly-typed Zap field in a key position to any of the logging methods (Log, Error).

Levels in logr correspond to custom debug levels in Zap. Any given level in logr is represents by its inverse in Zap (zapLevel = -1*logrLevel).

For example V(2) is equivalent to log level -2 in Zap, while V(1) is equivalent to Zap's DebugLevel.

Documentation

Overview

package zapr defines an implementation of the github.com/go-logr/logr interfaces built on top of Zap (go.uber.org/zap).

Usage

A new logr.Logger can be constructed from an existing zap.Logger using the NewLogger function:

log := zapr.NewLogger(someZapLogger)

Implementation Details

For the most part, concepts in Zap correspond directly with those in logr.

Unlike Zap, all fields *must* be in the form of suggared fields -- it's illegal to pass a strongly-typed Zap field in a key position to any of the log methods.

Levels in logr correspond to custom debug levels in Zap. Any given level in logr is represents by its inverse in zap (`zapLevel = -1*logrLevel`). For example V(2) is equivalent to log level -2 in Zap, while V(1) is equivalent to Zap's DebugLevel.
