logrus

A temporary logrus proxy to log/slog. Only used for the transition period until our projects are fully migrated. Please keep in mind this is an incomplete implementation, only functions used in osbuild projects are present.

How to use

package main

import (
	"context"
	"log/slog"
	"os"

	"github.com/osbuild/logging/pkg/logrus"
)

func main() {
	ctx := context.Background()
	slog.SetDefault(slog.New(slog.NewTextHandler(os.Stdout, &slog.HandlerOptions{Level: slog.LevelDebug})))
	logrus.SetDefault(logrus.NewProxy())

	logrus.Trace("a", "b", "c")
	logrus.Debug("a", "b", "c")
	logrus.Info("a", "b", "c")
	logrus.Warn("a", "b", "c")
	logrus.Error("a", "b", "c")
	logrus.Panic("a", "b", "c")

	logrus.Tracef("number: %d", 42)
	logrus.Debugf("number: %d", 42)
	logrus.Infof("number: %d", 42)
	logrus.Warnf("number: %d", 42)
	logrus.Errorf("number: %d", 42)
	logrus.Panicf("number: %d", 42)

	// context is supported and carries fields over to log/slog
	logrus.WithContext(ctx).Trace("msg with context")
	logrus.WithContext(ctx).Debug("msg with context")
	logrus.WithContext(ctx).Info("msg with context")
	logrus.WithContext(ctx).Warn("msg with context")
	logrus.WithContext(ctx).Error("msg with context")
	logrus.WithContext(ctx).Panic("msg with context")

	logrus.WithField("key", "value").Trace("msg with field")
	logrus.WithField("key", "value").Debug("msg with field")
	logrus.WithField("key", "value").Info("msg with field")
	logrus.WithField("key", "value").Warn("msg with field")
	logrus.WithField("key", "value").Error("msg with field")
	logrus.WithField("key", "value").Panic("msg with field")
}

Run the above example with:

go run github.com/osbuild/logging/internal/example_logrus/
