Functions

func Debugf

func Debugf(format string, args ...any)

func Err

func Err(err error) slog.Attr

Err returns an Attr that represents an error.

func Errorf

func Errorf(format string, args ...any)

func Fatal

func Fatal(msg string, args ...any)

Fatal for logging fatal errors

func Infof

func Infof(format string, args ...any)

func InitLogger

func InitLogger(debug, disable bool)

InitLogger initialize the logger variable

func Prefix

func Prefix(prefix string) slog.Attr

Prefix returns an Attr that represents a prefix.

func Warnf

func Warnf(format string, args ...any)

func WithContextAttrs

func WithContextAttrs(ctx context.Context, attrs ...slog.Attr) context.Context

WithContextAttrs returns a new context with the given attrs.

func WithContextPrefix

func WithContextPrefix(ctx context.Context, prefix string) context.Context

WithContextPrefix returns a new context with the given prefix.

Types

type ColorHandler

type ColorHandler struct {
	// contains filtered or unexported fields
}

func NewHandler

func NewHandler(out io.Writer, opts *Options) *ColorHandler

func (*ColorHandler) Enabled

func (h *ColorHandler) Enabled(_ context.Context, level slog.Level) bool

func (*ColorHandler) Err

func (h *ColorHandler) Err(r slog.Record) error

Err returns the error from the attrs, if any.

func (*ColorHandler) Handle

func (h *ColorHandler) Handle(ctx context.Context, r slog.Record) error

func (*ColorHandler) Prefix

func (h *ColorHandler) Prefix(ctx context.Context, r slog.Record) string

Prefix returns the prefix from the attrs, if any.

func (*ColorHandler) WithAttrs

func (h *ColorHandler) WithAttrs(attrs []slog.Attr) slog.Handler

func (*ColorHandler) WithGroup

func (h *ColorHandler) WithGroup(name string) slog.Handler

type Logger

type Logger = slog.Logger

Logger is an alias of slog.Logger

func New

func New(h slog.Handler) *Logger

New creates a new Logger with the given non-nil Handler.

func WithPrefix

func WithPrefix(prefix string) *Logger

WithPrefix calls [Logger.With] with the prefix on the default logger.

Note: If WithPrefix is called within init() or during global variable initialization, it will use the default logger of log/slog package before Trivy's logger is set up. In such cases, it's recommended to pass the prefix via WithContextPrefix to ensure the correct logger is used.

type Options

type Options struct {
	// Level reports the minimum level to log.
	// Levels with lower levels are discarded.
	// If nil, the Handler uses [slog.LevelInfo].
	Level slog.Leveler
}

type WriteLogger

type WriteLogger struct {
	// contains filtered or unexported fields
}

WriteLogger is a wrapper around Logger to implement io.Writer

func NewWriteLogger

func NewWriteLogger(logger *Logger) *WriteLogger

NewWriteLogger creates a new WriteLogger

func (*WriteLogger) Write

func (l *WriteLogger) Write(p []byte) (n int, err error)
