Types

type DirectoryFlag

type DirectoryFlag struct {
	cli.GenericFlag
	Name   string

	EnvVar string
}

Custom cli.Flag type which expand the received string to an absolute path. e.g. ~/.ethereum -> /home/username/.ethereum

func (DirectoryFlag) Apply

func (self DirectoryFlag) Apply(set *flag.FlagSet)

called by cli library, grabs variable from environment (if in env) and adds variable to flag set for parsing.

func (*DirectoryFlag) Set

func (self *DirectoryFlag) Set(value string)

func (DirectoryFlag) String

func (self DirectoryFlag) String() string

type DirectoryString

type DirectoryString struct {
	Value string
