Functions

func AskForConfirmation

func AskForConfirmation(s string) (bool, error)

askForConfirmation asks the user for confirmation. A user must type in "yes" or "no" and then press enter. It has fuzzy matching, so "y", "Y", "yes", "YES", and "Yes" all count as confirmations. If the input is not recognized, it will ask again. The function does not return until it gets a valid response from the user.

func EnvExists

func EnvExists(key string) bool

func GetEnv

func GetEnv(key, fallback string) string

func InArray

func InArray(a []string, v string) (ret bool, i int)

* InArray returns true if the value exists in the array

func IsBoolArrayTrue

func IsBoolArrayTrue(array []bool) bool

* IsBoolArrayTrue checks whether the array contains only true elements

func Max

func Max(x, y int64) int64

int64 max function

func Min

func Min(x, y int64) int64

int64 min function

func RandStringBytesMaskImprSrc

func RandStringBytesMaskImprSrc(n int) string

func RemoveCommonElements

func RemoveCommonElements(a, b []string) []string

* RemoveCommonElements removes the common elements and returns the first array

func TruncateString

func TruncateString(str string, n int) string

func YesNoToBool

func YesNoToBool(s string) bool
