A package level structured log/slog handler for Go

pkgslog

A package level structured log handler for log/slog.
pkgslog adds the ability to set minimum log level requirement per package.

Example

textHandler := slog.NewTextHandler(os.Stdout, nil)
packageMap := map[string]slog.Level{
    "github.com/reugn/pkgslog/internal":  slog.LevelWarn,
    "github.com/reugn/pkgslog/pkg":       slog.LevelDebug,
    "github.com/reugn/pkgslog/pkg/inner": slog.LevelInfo,
}
logger := slog.New(pkgslog.NewPackageHandler(textHandler, packageMap))
