Functions ¶
func Command ¶ added in v1.1.1
func Command() command
Command can be used to print how certain nctl commands can be executed.
func ExitIfErrorf ¶ added in v1.2.0

func PrettyPrintObjects ¶
PrettyPrintObjects prints the supplied objects in "pretty" colored yaml with some metadata, status and other default fields stripped out. If multiple objects are supplied, they will be divided with a yaml divider.
Types ¶
type JSONOutputOptions ¶ added in v1.9.0
type JSONOutputOptions struct {
// PrintSingleItem will print a single item of an array as is
// (without the array notation)
PrintSingleItem bool
}
type OutputFormatType ¶ added in v1.9.0
type OutputFormatType int
type PrintOpts ¶
type PrintOpts struct {
// Out will be used to print to if set instead of stdout.
Out io.Writer
// ExcludeAdditional allows to exclude more fields of the object
ExcludeAdditional [][]string
// format type of the output, e.g. yaml or json
Format OutputFormatType
// JSONOpts defines special options for JSON output
JSONOpts JSONOutputOptions
// AllFields prints all fields of the object.
AllFields bool
}
PrintOpts customizes the printing.
