Convert multi-language text to a US-ASCII, lowercase, hyphenated, URI-friendly "slug".

[![built with nix](https://builtwithnix.org/badge.svg)](https://builtwithnix.org)

## Usage

### Library

There are `Data.Text` and `Data.String` library interfaces to `slugger` that
have plenty of examples in [`the test file`](./test/SluggerTest.hs), and here
are some simple examples.

Example of `Data.String.Slugger`:

```haskell
import qualified Data.String.Slugger as SluggerString

SluggerString.toSlug "Hey there,   world!"
-- "hey-there-world"

SluggerString.toSlug "GARÇON - déjà , Forêt — Zoë"
-- "garcon-deja-foret-zoe"
```

Example of `Data.Text.Slugger`:

```haskell
import qualified Data.Text as T
import qualified Data.Text.Slugger as SluggerText

SluggerText.toSlug (T.pack "Hey there,   world!")
-- "hey-there-world"

SluggerText.toSlug (T.pack "GARÇON - déjà , Forêt — Zoë")
-- "garcon-deja-foret-zoe"
```

### Executable

```sh
λ slugger "Hey there,   world!"
hey-there-world

λ slugger "Pijamalı hasta yağız şoföre çabucak güvendi"
pijamali-hasta-yagiz-sofore-cabucak-guvendi
```
