Types

type JSONPrinter

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

JSONPrinter is a printer that outputs an object formatted as JSON

func (*JSONPrinter) LogObj

func (j *JSONPrinter) LogObj(log logger.Logger, msgFmt string, obj interface{}) error

LogObj will print the passed object formatted as JSON to the logger.

func (*JSONPrinter) PrintObj

func (j *JSONPrinter) PrintObj(obj interface{}, writer io.Writer) error

PrintObj will print the passed object formatted as JSON to the supplied writer.

func (*JSONPrinter) PrintObjWithKind

func (j *JSONPrinter) PrintObjWithKind(kind string, obj interface{}, writer io.Writer) error

PrintObjWithKind will print the passed object formatted as YAML to the supplied writer. This printer ignores kind argument.

type OutputPrinter

type OutputPrinter interface {
	PrintObjWithKind(kind string, obj interface{}, writer io.Writer) error
	PrintObj(obj interface{}, writer io.Writer) error
	LogObj(log logger.Logger, msgFmt string, obj interface{}) error
}

OutputPrinter is the interface that printer must implement. This allows new printers to be added in the future.

func NewJSONPrinter

func NewJSONPrinter() OutputPrinter

NewJSONPrinter creates a new JsonPrinter with defaults for level of indentation.

func NewPrinter

func NewPrinter(printerType Type) (OutputPrinter, error)

NewPrinter creates a new printer based in the printer type requested.

func NewTablePrinter

func NewTablePrinter() OutputPrinter

NewTablePrinter creates a new TablePrinter with defaults.

func NewYAMLPrinter

func NewYAMLPrinter() OutputPrinter

NewYAMLPrinter creates a new YAMLPrinter

type TablePrinter

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

TablePrinter is a printer that outputs an object formatted as table

func (*TablePrinter) AddColumn

func (t *TablePrinter) AddColumn(name string, getter interface{})

AddColumn adds a column to the table that will be printed

func (*TablePrinter) LogObj

func (t *TablePrinter) LogObj(log logger.Logger, msgFmt string, obj interface{}) error

LogObj will print the passed object formatted as a table to the logger.

func (*TablePrinter) PrintObj

func (t *TablePrinter) PrintObj(obj interface{}, writer io.Writer) error

PrintObj will print the passed object formatted as textual table to the supplied writer.

func (*TablePrinter) PrintObjWithKind

func (t *TablePrinter) PrintObjWithKind(kind string, obj interface{}, writer io.Writer) error

PrintObjWithKind will print the passed object formatted as textual table to the supplied writer.

type Type

type Type = string

Type is the type representing all supported printer types.

type YAMLPrinter

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

YAMLPrinter is a printer that outputs an object formatted as YAML

func (*YAMLPrinter) LogObj

func (y *YAMLPrinter) LogObj(log logger.Logger, msgFmt string, obj interface{}) error

LogObj will print the passed object formatted as YAML to the logger.

func (*YAMLPrinter) PrintObj

func (y *YAMLPrinter) PrintObj(obj interface{}, writer io.Writer) error

PrintObj will print the passed object formatted as YAML to the supplied writer.

func (*YAMLPrinter) PrintObjWithKind

func (y *YAMLPrinter) PrintObjWithKind(kind string, obj interface{}, writer io.Writer) error

PrintObjWithKind will print the passed object formatted as YAML to the supplied writer. This printer ignores kind argument.
