Zerologr
A logr LogSink implementation using Zerolog.
Usage
import (
"os"
"github.com/go-logr/logr"
"github.com/go-logr/zerologr"
"github.com/rs/zerolog"
)
func main() {
zerolog.TimeFieldFormat = zerolog.TimeFormatUnixMs
zerologr.NameFieldName = "logger"
zerologr.NameSeparator = "/"
zerologr.SetMaxV(1)
zl := zerolog.New(os.Stderr)
zl = zl.With().Caller().Timestamp().Logger()
var log logr.Logger = zerologr.New(&zl)
log.Info("Logr in action!", "the answer", 42)
}
Implementation Details
For the most part, concepts in Zerolog correspond directly with those in logr.
V-levels in logr correspond to levels in Zerolog as zerologLevel = 1 - logrV
. logr.V(0)
is equivalent to zerolog.InfoLevel
or 1; logr.V(1)
is equivalent to zerolog.DebugLevel
or 0 (default global level in Zerolog); logr.V(2)
is equivalent to zerolog.TraceLevel
or -1. Higher than 2 V-level is possible but misses some features in Zerolog, e.g. Hooks and Sampling. V-level value is a number and is only logged on Info(), not Error().
