# slug
Package `slug` generate slug from Unicode string, URL-friendly slugify with
multiple languages support.
[](https://pkg.go.dev/github.com/gosimple/slug)
[](https://github.com/gosimple/slug/actions/workflows/tests.yml)
[](https://codecov.io/gh/gosimple/slug)
[](https://github.com/gosimple/slug/releases)
## Example
```go
package main
import (
"fmt"
"github.com/gosimple/slug"
)
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.Lowercase = false // Keep uppercase characters
deUppercaseText := slug.MakeLang("Diese & Dass", "de")
fmt.Println(deUppercaseText) // Will print: "Diese-und-Dass"
slug.CustomSub = map[string]string{
"water": "sand",
}
textSub := slug.Make("water is hot")
fmt.Println(textSub) // Will print: "sand-is-hot"
}
```
## Design
This library will always returns clean output from any Unicode string
containing only the following ASCII characters:
* numbers: `0-9`
* small letters: `a-z`
* big letters: `A-Z` (only if you set `Lowercase` to `false`)
* minus sign: `-`
* underscore: `_`
Minus sign and underscore characters will never appear at the beginning or
the end of the returned string.
Thanks to context-insensitive transliteration of Unicode characters to ASCII
output returned string is safe for URL slugs and filenames.
## Requests or bugs?
<https://github.com/gosimple/slug/issues>
If your language is missing you could add it in `languages_substitution.go`
file.
In case of missing proper Unicode characters transliteration to ASCII you could
add them to underlying library:
<https://github.com/gosimple/unidecode>.
