Functions

func After

func After(value string, a string) (string, error)

After extracts the string after a from value returns value as is and error if a is not found

func Before

func Before(value string, a string) (string, error)

Before extracts the string before a from value returns value as is and error if a is not found

func Between

func Between(value string, a string, b string) (string, error)

Between extracts the string between a and b returns value as is and error if a or b are not found

func ContainsAny

func ContainsAny(s string, ss ...string) bool

ContainsAny returns true if s contains any specified substring.

func ContainsAnyI

func ContainsAnyI(s string, ss ...string) bool

ContainsAnyI returns true if s contains any specified substring (case-insensitive).

func EqualFoldAny

func EqualFoldAny(s string, ss ...string) bool

EqualFoldAny returns true if s is equal to any specified substring

func HasPrefixAny

func HasPrefixAny(s string, prefixes ...string) bool

HasPrefixAny checks if the string starts with any specified prefix

func HasPrefixAnyI

func HasPrefixAnyI(s string, prefixes ...string) bool

HasPrefixAnyI is case insensitive HasPrefixAny

func HasPrefixI

func HasPrefixI(s, prefix string) bool

HasPrefixI is case insensitive HasPrefix

func HasSuffixAny

func HasSuffixAny(s string, suffixes ...string) bool

HasSuffixAny checks if the string ends with any specified suffix

func HasSuffixI

func HasSuffixI(s, suffix string) bool

HasSuffixI is case insensitive HasSuffix

func IndexAny

func IndexAny(s string, seps ...string) (int, string)

IndexAny returns the index of the first instance of any of the specified substrings in s, or -1 if s does not contain any of the substrings.

func IndexAt

func IndexAt(s, sep string, n int) int

IndexAt look for a substring starting at position x

func IsCTRLC

func IsCTRLC(s string) bool

IsCTRLC checks if the string is CTRL+C

func IsPrintable

func IsPrintable(s string) bool

IsPrintable checks if the strings is made only of printable characters

func Join

func Join(elems []interface{}, sep string) string

Join concatenates the elements of its first argument to create a single string. The separator string sep is placed between elements in the resulting string.

func Normalize

func Normalize(data string) string

func NormalizeWithOptions

func NormalizeWithOptions(data string, options NormalizeOptions) string

func ReplaceAll

func ReplaceAll(s, new string, olds ...string) string

ReplaceAll returns a copy of the string s with all instances of old incrementally replaced by new.

func Reverse

func Reverse(s string) string

Reverse the string

func SlideWithLength

func SlideWithLength(s string, l int) chan string

SlideWithLength returns all the strings of the specified length while moving forward the extraction window

func SplitAny

func SplitAny(s string, seps ...string) []string

SplitAny string by a list of separators

func TrimPrefixAny

func TrimPrefixAny(s string, prefixes ...string) string

TrimPrefixAny trims all prefixes from string in order

func TrimSuffixAny

func TrimSuffixAny(s string, suffixes ...string) string

TrimSuffixAny trims all suffixes from string in order

func Truncate

func Truncate(data string, maxSize int) string

Truncate a string to max length
