Functions

func CheckErr

func CheckErr(err error)

CheckErr prints a user-friendly error to STDERR and exits with a non-zero exit code. Unrecognized errors will be printed with an "error: " prefix.

This method is generic to the command in use and may be used by non commands.

func DefaultSubCommandRun

DefaultSubCommandRun prints a command's help string to the specified output if no arguments (sub-commands) are provided, or a usage error otherwise.

func MultilineError

func MultilineError(prefix string, err error) string

MultilineError returns a string representing an error that splits sub errors into their own lines. The returned string will end with a newline.

func MultipleErrors

func MultipleErrors(prefix string, errs []error) string

MultipleErrors returns a newline delimited string containing the prefix and referenced errors in standard form.

func RequireNoArguments

func RequireNoArguments(c *cobra.Command, args []string)

RequireNoArguments exits with a usage error if extra arguments are provided.

func StandardErrorMessage

func StandardErrorMessage(err error) (string, bool)

StandardErrorMessage translates common errors into a human readable message, or returns false if the error is not one of the recognized types. It may also log extended information to klog.

This method is generic to the command in use and may be used by non-IAM commands.

func TableWriterDefaultConfig

func TableWriterDefaultConfig(table *tablewriter.Table) *tablewriter.Table

func UsageErrorf

func UsageErrorf(cmd *cobra.Command, format string, args ...interface{}) error
