Functions ¶
func After ¶
After returns the substring after the first occurrence of a specified string in the source string
Example:
After("hello world", "o") -> " world"
func AfterLast ¶
AfterLast returns the substring after the last occurrence of a specified string in the source string
Example:
AfterLast("hello world", "o") -> "rld"
func Before ¶
Before returns the string before the first occurrence of ch.
Example:
Before("no-separator", "-") -> "no"
func BeforeLast ¶
BeforeLast returns the string before the last occurrence of ch.
Example:
BeforeLast("abcabc", "c") -> "abcab"
func BytesToString ¶
BytesToString converts the byte slice to string without memory alloc.
func CamelCase ¶
CamelCase converts string to camelCase string. Non letters and numbers will be ignored.
Example: "!@#" -> "" "&FOO:BAR$BAZ" -> "fooBarBaz" "hello_world" -> "helloWorld"
func Capitalize ¶
Capitalize converts first character of string to upper case and the remaining to lower case.
Example: "hello" -> "Hello" "GoLang" -> "Golang"
func Concat ¶
Concat uses the strings.Builder to concatenate the input strings.
- `length` is the expected length of the concatenated string.
- If unsure about the length of string to be concatenated, length set to 0 / negetive number.
func ContainChinese ¶
ContainChinese check if the string contains Chinese characters.
func ContainLetter ¶
ContainLetter checks if the string contains any letters (a-zA-Z).
func ContainLower ¶
ContainLower checks if the string contains any lower letters (a-z).
func ContainNumber ¶
ContainNumber checks if the string contains any numbers (0-9).
func ContainUpper ¶
ContainUpper checks if the string contains any upper letters (A-Z).
func ContainsAll ¶
ContainsAll checks if the string contains all substrings.
func ContainsAny ¶
ContainsAny checks if the string contains any substring.
func Ellipsis ¶
Ellipsis returns a string with ellipsis if the string is longer than the specified size.
func HammingDistance ¶
HammingDistance returns the Hamming distance between two strings.
func HasPrefixAny ¶
HasPrefixAny checks if the string has any of the given prefixes.
func HasSuffixAny ¶
HasSuffixAny checks if the string has any of the given suffixes.
func HideString ¶
HideString hides the string between beg and end with the hideChar.
Example:
HideString({"hello world", 3, 7, "*") -> "hel****orld"
func IndexOffset ¶
IndexOffset return the index of the first occurrence of the substring in the string after offset, or -1 if not found.
func IsAllLower ¶
IsAllLower checks if the string is all lower letters (a-z).
func IsAllUpper ¶
IsAllUpper checks if the string is all upper letters (A-Z).
func IsAmericanExpress ¶
IsAmericanExpress check if a give string is a valid american expression card nubmer or not.
func IsBase64URL ¶
IsBase64URL check if the string is a valid RUL-safe Base64 encoded string.
func IsChinaUnionPay ¶
IsChinaUnionPay check if a give string is a valid china union pay nubmer or not.
func IsChineseIDNum ¶
IsChineseIDNum check if the string is a valid Chinese ID card number.
func IsChineseMobile ¶
IsChineseMobile check if the string is a valid Chinese mobile phone number.
func IsChinesePhone ¶
IsChinesePhone check if the string is chinese phone number. Valid chinese phone is xxx-xxxxxxxx or xxxx-xxxxxxx.
func IsCreditCard ¶
IsCreditCard check if the string is credit card.
func IsEmptyString ¶
IsEmptyString check if the string is empty.
func IsFloatStr ¶
IsFloatStr check if the string can convert to a float.
func IsGBK ¶
IsGBK check if data encoding is gbk Note: this function is implemented by whether double bytes fall within the encoding range of gbk, while each byte of utf-8 encoding format falls within the encoding range of gbk. Therefore, utf8.valid() should be called first to check whether it is not utf-8 encoding, and then call IsGBK() to check gbk encoding. like below *
data := []byte("你好")
if utf8.Valid(data) {
fmt.Println("data encoding is utf-8")
}else if(IsGBK(data)) {
fmt.Println("data encoding is GBK")
}
fmt.Println("data encoding is unknown")
*
func IsInt ¶
IsInt check if value is a integer (int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64, uintptr) or not.
func IsMasterCard ¶
IsMasterCard check if a give string is a valid master card nubmer or not.
func IsNotSpace ¶
IsNotSpace checks if the string is not whitespace, empty or not.
func IsNumberStr ¶
IsNumberStr check if the string can convert to a number.
func IsRegexMatch ¶
IsRegexMatch check if the string match the regexp.
func IsSpace ¶
IsSpace checks if the string is whitespace, empty or not.
Example: "" -> true " \t\n\r" -> true
func IsStrongPassword ¶

("abc123",`(\w)(\w)(\w)`) -> [][]string{{"abc", "a", "b", "c"}, {"123", "1", "2", "3"}}
func RemoveNonPrintable ¶
RemoveNonPrintable removes all non-printable characters from the string.
func RemoveWhiteSpace ¶
RemoveWhiteSpace removes withespace from the string. When rmAll is true, all whitespaces are removed, otherwise only consective whitespaces are removed.
Example:
RemoveWhiteSpace(" hello world ", false) -> "hello world"
