Functions

func DataDir

func DataDir() string

DataDir retuns the data directory iff one is set.

func DataDirOrPwd

func DataDirOrPwd() (string, error)

DataDirOrPwd returns the data directory iff one is set, pwd otherwise.

func EarlyLogAndExit

func EarlyLogAndExit(err error)

EarlyLogAndExit logs the error and exits.

Note: This routine should only be used prior to the logging system being initialized.

func ExportEntity

func ExportEntity(signerBackend, entityDir string) error

ExportEntity creates an empty entity from the public key of the signer generated with the specified backend, and writes it to a file in entityDir.

func GetInputReader

func GetInputReader(cmd *cobra.Command, cfg string) (io.ReadCloser, bool, error)

GetInputReader will open a file if the config string is set, and otherwise return os.Stdin.

func GetOutputWriter

func GetOutputWriter(cmd *cobra.Command, cfg string) (io.WriteCloser, bool, error)

GetOutputWriter will create a file if the config string is set, and otherwise return os.Stdout.

func GetUserConfirmation

func GetUserConfirmation(prompt string) bool

GetUserConfirmation displays the prompt, and scans the input for the user's confirmation, until the user either explicitly confirms or rejects the prompt.

Note: If standard input is not a tty, this will omit displaying the prompt, and assume the user entered yes.

func Init

func Init() error

Init initializes the common environment across all commands.

func InitConfig

func InitConfig()

InitConfig initializes the command configuration.

WARNING: This is exposed for the benefit of tests and the interface is not guaranteed to be stable.

func IsNodeCmd() bool

IsNodeCmd returns true iff the current command is the ekiden node.

func Isatty

func Isatty(fd uintptr) bool

Isatty returns true iff the provided file descriptor is a terminal.

func LoadEntity

func LoadEntity(signerBackend, entityDir string) (*entity.Entity, signature.Signer, error)

LoadEntity loads the entity and it's signer.

func Logger

func Logger() *logging.Logger
