Types

type BaseElement 

type BaseElement interface {
	any
}

BaseElement represent any element that needs to be transform into a requested format. For instance, it could be an event (for trace category) or a report (for the profile/cpu gadget).

type BaseParser 

type BaseParser[E BaseElement] struct {
	// ColumnsWidth are the columns that can be configured to be printed with
	// the width to be used.
	ColumnsWidth map[string]int

	// SeparateWithTabs defines whether the columns has to be separated with the
	// width defined in ColumnsWidth (if false), or with tabs ignoring the width
	// defined in ColumnsWidth (if true).
	SeparateWithTabs bool

	// OutputConfig provides to the parser the flags that describes how to print
	// the gadget's output.
	OutputConfig *OutputConfig
}

BaseParser is a base for a parser that implements the most common methods.

func NewBaseTabParser 

func NewBaseTabParser[E BaseElement](availableColumns []string, outputConfig *OutputConfig) BaseParser[E]

NewBaseTabParser returns a BaseParser configured to print columns separated by tabs.

func NewBaseWidthParser 

func NewBaseWidthParser[E BaseElement](columnsWidth map[string]int, outputConfig *OutputConfig) BaseParser[E]

NewBaseWidthParser returns a BaseParser configured to print columns separated by their predefined with.

func (*BaseParser[E]) BuildColumnsHeader 

func (p *BaseParser[E]) BuildColumnsHeader() string

func (*BaseParser[E]) GetOutputConfig 

func (p *BaseParser[E]) GetOutputConfig() *OutputConfig

func (*BaseParser[E]) Transform 

func (p *BaseParser[E]) Transform(element *E, toColumns func(*E) string) string

type GadgetParser 

type GadgetParser[T any] struct {
	// contains filtered or unexported fields
}

GadgetParser is a parser that helps printing the gadget output in columns using the columns and formatter/textcolumns packages.

func NewGadgetParser 

func NewGadgetParser[T any](outputConfig *OutputConfig, cols *columns.Columns[T], options ...Option) (*GadgetParser[T], error)

func NewGadgetParserWithK8sAndRuntimeInfo added in v0.21.0 

func NewGadgetParserWithK8sAndRuntimeInfo[T any](outputConfig *OutputConfig, columns *columns.Columns[T]) (*GadgetParser[T], error)

func NewGadgetParserWithK8sInfo 

func NewGadgetParserWithK8sInfo[T any](outputConfig *OutputConfig, columns *columns.Columns[T]) (*GadgetParser[T], error)

func NewGadgetParserWithRuntimeInfo 

func NewGadgetParserWithRuntimeInfo[T any](outputConfig *OutputConfig, columns *columns.Columns[T]) (*GadgetParser[T], error)

func (*GadgetParser[T]) BuildColumnsHeader 

func (p *GadgetParser[T]) BuildColumnsHeader() string

func (*GadgetParser[T]) Sort 

func (p *GadgetParser[T]) Sort(entries []*T, sortBy []string)

	// List of columns to print (only meaningful when OutputMode is "columns=...")
	CustomColumns []string

	// Verbose prints additional information
	Verbose bool
}

OutputConfig contains the flags that describes how to print the gadget's output
