Constants

const AlphaAll = AlphaLower + AlphaUpper + AlphaNum

const AlphaLower = "abcdefghijklmnopqrstuvwxyz"

const AlphaNum = "0123456789"

const AlphaUpper = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

const Token68 = AlphaAll + "-._~+/"

Functions

func AtoInt64

func AtoInt64(s string) int64

AtoInt64 converts a string to Int64.

func AtoUint

func AtoUint(s string) uint

AtoUint converts a string to uint.

func AtoUint64

func AtoUint64(s string) uint64

AtoUint64 converts a string to uint64.

func CamelToKebab

func CamelToKebab(camelCase string) string

CamelToKebab converts a camel case string to kebab case. If it encounters a character that is not legitimate camel case, it ignores it (like numbers, spaces, etc.). Runs of upper case letters are treated as one word.

Example

a := CamelToKebab("AbcDef")
fmt.Println(a)
b := CamelToKebab("AbcDEFghi")
fmt.Println(b)

Output:

abc-def
abc-de-fghi

func CamelToSnake

func CamelToSnake(camelCase string) string

CamelToSnake converts a camel case string to snake case. If it encounters a character that is not legitimate camel case, it ignores it (like numbers, spaces, etc.). Runs of upper case letters are treated as one word. A run of upper case, followed by lower case letters will be treated as if the final character in the upper case run belong with the lower case letters.

Example

a := CamelToSnake("AbcDef")
fmt.Println(a)
b := CamelToSnake("AbcDEFghi")
fmt.Println(b)

Output:

abc_def
abc_de_fghi

func ContainsAnyStrings

func ContainsAnyStrings(haystack string, needles ...string) bool

ContainsAnyStrings returns true if the haystack contains any of the needles

func CryptoString

func CryptoString(source string, n int) string

CryptoString returns a cryptographically secure random string from the given source. Use AlphaAll, AlphaUpper, AlphaLower, or AlphaNum as shortcuts for source.

func EndsWith

func EndsWith(s string, ending string) bool

EndsWith returns true if the string ends with the ending string.

func ExtractNumbers

func ExtractNumbers(in string) (out string)

ExtractNumbers returns a string with the digits contained in the given string.

Example

a := ExtractNumbers("a1b2 c3")
fmt.Println(a)

Output:

123

func HasCharType

func HasCharType(s string, wantUpper, wantLower, wantDigit, wantPunc, wantSymbol bool) bool

HasCharType returns true if the given string has at least one of all the selected char types.

func HasOnlyLetters

func HasOnlyLetters(s string) bool

HasOnlyLetters will return false if any of the characters in the string do not pass the unicode.IsLetter test.

func If

func If(cond bool, trueVal, falseVal string) string

If is like the ternary operator ?. It returns the first string on true, and the second on false.

func Indent

func Indent(s string) string

Indent will indent every line of the string with a tab

func JoinContent

func JoinContent(sep string, items ...string) string

JoinContent joins strings together with the separator sep. Only strings that are not empty strings are joined.

Example

a := JoinContent("+", "this", "", "that")
fmt.Println(a)

Output:

this+that

func KebabToCamel

func KebabToCamel(s string) string

KebabToCamel convert kebab-case words to CamelCase words.

Example

a := KebabToCamel("abc-def")
fmt.Println(a)

Output:

AbcDef

func LcFirst

func LcFirst(s string) string

LcFirst makes sure the first character in the string is lower case.

func PasswordString

func PasswordString(n int) string

PasswordString generates a pseudo random password with the given length using characters that are common in passwords. We attempt to leave out letters that are easily visually confused. Specific letters excluded are lowercase l, upper case I and the number 1, upper case O and the number 0 Also, only easily identifiable and describable symbols are used. It also tries to protect against accidentally creating an easily guessed value by making sure the password has at least one lower-case letter, one upper-case letter, one number, and one symbol. n must be at least 4

func RandomString

func RandomString(source string, n int) string

RandomString generates a pseudo random string of the given length using the given characters. The distribution is not perfect, but works for general purposes

func ReplaceStrings

func ReplaceStrings(s string, searchList []string, replaceList []string) string

ReplaceStrings is a memory efficient string replacer, replacing every string in the searchList with the matching string in the replaceList.

func SnakeToKebab

func SnakeToKebab(s string) string

SnakeToKebab converts snake_case words to kebab-case words.

Example

a := SnakeToKebab("abc_def")
fmt.Println(a)

Output:

abc-def

func StartsWith

func StartsWith(s string, beginning string) bool

StartsWith returns true if the string begins with the beginning string.

func Title

func Title(s string) string

Title is a more advanced titling operation. It will convert underscores to spaces, and add spaces to CamelCase words.

Example

a := Title("do_i_seeYou")
fmt.Println(a)

Output:

Do I See You
