logrus

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. Features:

• Basic functions and methods implemented.
• Context support.
• Fields are ignored.

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)

	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/
