# Language catalog

HTML: [altophp.com/language/catalog](https://altophp.com/language/catalog/)

The bundled registry contains 62 language definitions. Use the catalog for
selection and discovery; use [Lookup](https://altophp.com/language/lookup.md) when an identifier is already
known.

```php
use Alto\Language\LanguageType;
use Alto\Language\Languages;

$all = Languages::all();
$templates = Languages::ofType(LanguageType::Template);
$javascriptFamily = Languages::children('javascript');
```

`all()` preserves definition loading order. `ofType()` and `children()` return
filtered lists of `Language` objects.
