Functions

func Fold

func Fold(s string) string

Fold transforms all runes to their canonical width. unicode string

func Narrow

func Narrow(s string) string

Narrow transforms all runes to the narrow unicode string

func Or

func Or(arr ...string) string

func SplitAndTrimAsMap

func SplitAndTrimAsMap(s string, sep string) map[string]struct{}

SplitAndTrimAsMap is like SplitAndTrim but returns an map[string]bool where the map key is the string flagment included in

Example

m := SplitAndTrimAsMap("a, b, c ,d,,f,", ",")

_, not := m["z"]
fmt.Println(ok, not)

Output:

true false

func ToSnakeCase

func ToSnakeCase(s string) string

fmt.Println(
	ToSnakeCase("A"),
	ToSnakeCase("FooBar"),
	ToSnakeCase("APIDoc"),
