logs

Based on slog packaging, supports context tracking

Example

var (
    level   slog.LevelVar // info
    syncer  = &lumberjack.Logger{Filename: "logger.log", LocalTime: true, MaxAge: 1}
)

func main() {
	
    defer syncer.Close()
    
    level.Set(logs.ParseLevel("debug"))

    slog.SetDefault(slog.New(WrapHandler(slog.NewJSONHandler(
        io.MultiWriter(os.Stdout, NewWriter(syncer, 10<<10)),
        &slog.HandlerOptions{Level: &level}),
    )))

    slog.DebugContext(ctx, "DebugContext")
    slog.InfoContext(ctx, "InfoContext")
    slog.ErrorContext(ctx, "ErrorContext")
    son := slog.With(slog.String("name", "son"))
    son.ErrorContext(ctx, "son.ErrorContext")
}
