type PrettyTextOptions

type PrettyTextOptions struct {

	// AddSource adds slog.SourceKey attr, same idea as slog.HandlerOptions.AddSource.
	AddSource bool

	// ReplaceAttr is called to rewrite or drop attributes.
	//
	// To drop an attr, return slog.Attr{}.
	//
	// Built-in attrs passed to ReplaceAttr:
	//   - slog.TimeKey
	//   - slog.LevelKey
	//   - slog.SourceKey, when AddSource is true
	//
	// Message is not passed through ReplaceAttr because this handler prints it
	// as the fixed main log text.
	ReplaceAttr func(groups []string, attr slog.Attr) slog.Attr

	// TimeFormat controls timestamp rendering.
	// Default: "2006-01-02 15:04:05".
