Variables

var DisallowedLabelCharacters = regexp.MustCompile("[^a-z0-9-]")

DisallowedLabelCharacters regex of chars not allowed in lables

Functions

func CheckMark

func CheckMark() string

CheckMark returns the check mark unicode character. We could configure this to use no color or avoid unicode using platform, env vars or config?

func DiffSlices

func DiffSlices(oldSlice []string, newSlice []string) ([]string, []string)

DiffSlices compares the two slices and returns an array of items to delete from the old slice and a slice of new values to add to

func EnsureStringArrayContains

func EnsureStringArrayContains(slice []string, token string) []string

EnsureStringArrayContains appends token to slice if token isn't already in slice

func ExtractKeyValuePairs

func ExtractKeyValuePairs(values []string, sep string) (map[string]string, error)

ExtractKeyValuePairs creates a map of an string array assuming that each array element is of the form <key><sep><value>. An error is returned is a array element cannot be split into a key/value pair using the specified separator.

func FirstNotEmptyString

func FirstNotEmptyString(values ...string) string

FirstNotEmptyString returns the first non empty string or the empty string if none can be found

func HasPrefix

func HasPrefix(text string, prefixes ...string) bool

HasPrefix returns true if the given string has one of the prefixes

func HasSuffix

func HasSuffix(text string, suffixes ...string) bool

HasSuffix returns true if the given string has one of the suffixes

func IsValidUrl

func IsValidUrl(s string) bool

IsValidUrl tests a string to determine if it is a well-structured url or not.

func ParseBool

func ParseBool(text string) (bool, error)

ParseBool parses the boolean string. Returns false if the string is empty

func RandStringBytesMaskImprSrc

func RandStringBytesMaskImprSrc(n int) (string, error)

RandStringBytesMaskImprSrc returns a random hexadecimal string of length n.

func RegexpSplit

func RegexpSplit(text string, regexSeperator string) []string

RegexpSplit splits a string into an array using the regexSep as a separator

func RemoveStringFromSlice

func RemoveStringFromSlice(strings []string, toRemove string) []string

RemoveStringFromSlice removes the first occurrence of the specified string from a slice, if it exists and returns the result

func ReplaceAllStringSubmatchFunc

func ReplaceAllStringSubmatchFunc(re *regexp.Regexp, str string, repl func(groups []Group) []string) string

ReplaceAllStringSubmatchFunc will replace all the submatches found in str by re by calling repl and replacing each submatch with the result. Both the argument and the result of repl ignore the entire match (i.e. the item at index 0 is the first submatch)

func ReverseStrings

func ReverseStrings(a []string)

func SanitizeURL

func SanitizeURL(unsanitizedUrl string) string

SanitizeURL sanitizes by stripping the user and password

func StringArrayToLower(values []string) []string

StringArrayToLower returns a string slice with all the values converted to lower case

func StringArraysEqual

func StringArraysEqual(a1 []string, a2 []string) bool

StringArraysEqual returns true if the two string slices are equal

func StringContainsAny

func StringContainsAny(text string, includes []string, excludes []string) bool

StringContainsAny returns true if the given text contains the includes/excludes lists
