HmacSHA1 returns the HMAC-SHA1 tag for the given message and key, as a base64 encoded string.

func HmacSHA256 ¶

func HmacSHA256(message, key string) string

HmacSHA256 returns the HMAC-SHA256 tag for the given message and key, as a base64 encoded string.

func HtmlEscape ¶

func HtmlEscape(s string) templates.HTML

HtmlEscape escapes s, replacing the characters <, >, &, " and ' and returns the escaped string as templates.HTML type.

func Index ¶

func Index(s, substr string) int

Index returns the index of the first instance of substr in s, or -1 if substr is not present in s.

func IndexAny ¶

func IndexAny(s, chars string) int

IndexAny returns the index of the first instance of any Unicode code point from chars in s, or -1 if no Unicode code point from chars is present in s.

func Join ¶

func Join(elems []string, 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 LastIndex ¶

func LastIndex(s, substr string) int

LastIndex returns the index of the last instance of substr in s, or -1 if substr is not present in s.

func Max ¶

func Max(x, y int) int

Max returns the larger of x or y.

func Md5 ¶

func Md5(src string) string

Md5 returns the MD5 checksum of src as an hexadecimal encoded string.

func Min ¶

func Min(x, y int) int

Min returns the smaller of x or y.

func QueryEscape ¶

func QueryEscape(s string) string

QueryEscape escapes the string so it can be safely placed inside a URL query.

func Replace ¶

func Replace(s, old, new string, n int) string

Replace returns a copy of the string s with the first n non-overlapping instances of old replaced by new. If old is empty, it matches at the beginning of the string and after each UTF-8 sequence, yielding up to k+1 replacements for a k-rune string. If n < 0, there is no limit on the number of replacements.

func ReplaceAll ¶

func ReplaceAll(s, old, new string) string

ReplaceAll returns a copy of the string s with all non-overlapping instances of old replaced by new. If old is empty, it matches at the beginning of the string and after each UTF-8 sequence, yielding up to k+1 replacements for a k-rune string.

func Reverse ¶

func Reverse(data interface{})

Reverse returns the reverse order for data.

func RuneCount ¶

func RuneCount(s string) (n int)

RuneCount returns the number of runes in s. Erroneous and short encodings are treated as single runes of width 1 byte.

func Sha1 ¶

func Sha1(src string) string

Sha1 returns the SHA1 checksum of src as an hexadecimal encoded string.

func Sha256 ¶

func Sha256(s string) string

Sha256 returns the SHA256 checksum of src as an hexadecimal encoded string.

func Sort ¶

func Sort(slice interface{}, less func(i, j int) bool)

Sort sorts the provided slice given the provided less function.

The function panics if the provided interface is not a slice.

func Split ¶

func Split(s, sep string) []string

Split slices s into all substrings separated by sep and returns a slice of the substrings between those separators.

If s does not contain sep and sep is not empty, Split returns a slice of length 1 whose only element is s.

If sep is empty, Split splits after each UTF-8 sequence. If both s and sep are empty, Split returns an empty slice.

It is equivalent to SplitN with a count of -1.

func SplitN ¶

func SplitN(s, sep string, n int) []string

SplitN slices s into substrings separated by sep and returns a slice of the substrings between those separators.

The count determines the number of substrings to return:

n > 0: at most n substrings; the last substring will be the unsplit remainder.
n == 0: the result is nil (zero substrings)
n < 0: all substrings

Edge cases for s and sep (for example, empty strings) are handled as described in the documentation for Split.

func Sprint ¶

func Sprint(a ...interface{}) string

Sprint formats using the default formats for its operands and returns the resulting string. Spaces are added between operands when neither is a string.

func Sprintf ¶

func Sprintf(format string, a ...interface{}) string

Sprintf formats according to a format specifier and returns the resulting string.

func ToKebab ¶

func ToKebab(s string) string

ToKebab returns a copy of the string s in kebab case form.

func ToLower ¶

func ToLower(s string) string

ToLower returns s with all Unicode letters mapped to their lower case.

func ToUpper ¶

func ToUpper(s string) string

ToUpper returns s with all Unicode letters mapped to their upper case.

func Trim ¶

func Trim(s, cutset string) string

Trim returns a slice of the string s with all leading and trailing Unicode code points contained in cutset removed.

func TrimLeft ¶

func TrimLeft(s, cutset string) string

TrimLeft returns a slice of the string s with all leading Unicode code points contained in cutset removed.

To remove a prefix, use TrimPrefix instead.

func TrimPrefix ¶

func TrimPrefix(s, prefix string) string

TrimPrefix returns s without the provided leading prefix string. If s doesn't start with prefix, s is returned unchanged.

func TrimRight ¶

func TrimRight(s, cutset string) string

TrimRight returns a slice of the string s, with all trailing Unicode code points contained in cutset removed.

To remove a suffix, use TrimSuffix instead.

func TrimSuffix ¶

func TrimSuffix(s, suffix string) string

TrimSuffix returns s without the provided trailing suffix string. If s doesn't end with suffix, s is returned unchanged.
