Functions ¶

func SubCmdRunE ¶

func SubCmdRunE(name string) func(*cobra.Command, []string) error

SubCmdRunE returns a function that handles a case where a subcommand must be specified Without this callback, if a user runs just the command without a subcommand, or with an invalid subcommand, cobra will print usage information, but still exit cleanly. We want to return an error code in these cases so that the user knows that their command was invalid.

func ValidateExactArgNumber ¶

func ValidateExactArgNumber(args []string, supportedArgs []string) error

ValidateExactArgNumber validates that the required top-level arguments are specified
