Types

type ColorMode

type ColorMode string

ColorMode defines color mode flags for compact output.

const (
	Always ColorMode = "always" // always enable colored output.
	Never  ColorMode = "never"  // disable colored output.
	Auto   ColorMode = "auto"   // automatically enable / disable colored output based on terminal settings.
)

type Colorer

type Colorer struct {
	Colors  []*color.Color
	Red     *color.Color
	Green   *color.Color
	Blue    *color.Color
	Cyan    *color.Color
	Magenta *color.Color
	Yellow  *color.Color
}

func NewColorer

func NewColorer(when ColorMode) *Colorer

func (*Colorer) ProcessInfo

func (c *Colorer) ProcessInfo(host string, process *tetragon.Process) (string, string)

type CompactEncoder

type CompactEncoder struct {
	Writer      io.Writer
	Colorer     *Colorer
	Timestamps  bool
	StackTraces bool
	ImaHash     bool
}

CompactEncoder encodes tetragon.GetEventsResponse in a short format with emojis and colors.

func NewCompactEncoder

NewCompactEncoder initializes and returns a pointer to CompactEncoder.

func (*CompactEncoder) Encode

func (p *CompactEncoder) Encode(v interface{}) error

Encode implements EventEncoder.Encode.

func (*CompactEncoder) EventToString

func (p *CompactEncoder) EventToString(response *tetragon.GetEventsResponse) (string, error)

type EventEncoder

type EventEncoder interface {
	Encode(v interface{}) error
}

EventEncoder is an interface for encoding tetragon.GetEventsResponse.

type ProtojsonEncoder

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

func NewProtojsonEncoder

func NewProtojsonEncoder(w io.Writer) *ProtojsonEncoder

func (*ProtojsonEncoder) Encode

func (p *ProtojsonEncoder) Encode(v interface{}) error

type TtyEncoder

type TtyEncoder struct {
	Writer io.Writer
	Tty    string
}

func NewTtyEncoder

func NewTtyEncoder(w io.Writer, tty string) *TtyEncoder
