## Example

package main

|
||||
"fmt"

)
|
||||
|
||||
func main () {
|
||||
text := slug.Make("Hellö Wörld хелло ворлд")
|
||||
fmt.Println(text) // Will print hello-world-khello-vorld
|
||||
|
||||
someText := slug.Make("影師")
|
||||
fmt.Println(someText) // Will print: ying-shi
|
||||
|
||||
enText := slug.MakeLang("This & that", "en")
|
||||
fmt.Println(enText) // Will print 'this-and-that'
|
||||
|
||||
deText := slug.MakeLang("Diese & Dass", "de")
|
||||
fmt.Println(deText) // Will print 'diese-und-dass'
|

slug.CustomSub = map[string]string{

textSub := slug.Make("water is hot")
