Functions

func AbsPathify

func AbsPathify(inPath string) string

AbsPathify ...

func CIDRToIPv4Range

func CIDRToIPv4Range(cidr string) (string, string, error)

CIDRToIPv4Range converts CIDR to IPv4 range

func CIDRToLongRange

func CIDRToLongRange(cidr string) (uint32, uint32, error)

CIDRToLongRange converts CIDR to range of long values (representing IPv4 addresses)

func Capitalize

func Capitalize(value string) string

Capitalize makes the first letter of the first word uppercased

func Check

func Check(port int) (status bool, err error)

Check if a port is available

func ExtractRetCode

func ExtractRetCode(err error) (string, int, error)

ExtractRetCode extracts info from the error

func GeneratePassword

func GeneratePassword(length uint8) (string, error)

GeneratePassword generates a password with length at least 12

func IPv4ToLong

func IPv4ToLong(ip string) uint32

IPv4ToLong converts IPv4 to uint32

func IsCIDRRoutable

func IsCIDRRoutable(cidr string) (bool, error)

IsCIDRRoutable tells if the network is routable

func IsEmpty

func IsEmpty(v interface{}) bool

IsEmpty checks whether v is an empty struct

func LazyRemove

func LazyRemove(path string) error

LazyRemove is identical to os.Remove, but doesn't raise an error, and log.Warn every error except "file not found" which is ignored

func LongToIPv4

func LongToIPv4(value uint32) string

LongToIPv4 converts uint32 to IP

func New

func New() (port int, err error)

New gets an available port

func Plural

func Plural(value int) string

Plural returns 's' if value > 1, "" otherwise

func UserConfirmed

func UserConfirmed(msg string) bool

UserConfirmed asks user to confirm
