The license also allows you to fork it and make changes as needed for legacy support reasons. Instead, use [Twig 3.1.5's native functionality](https://github.com/twigphp/Twig/issues/3192) for arrow functions everywhere. Closure for Craft CMS ===================== [](#closure-for-craft-cms) Allows you to use arrow function closures in Twig While Closure is a bit of a monkey patch, it's a pretty clean/simple one that relies on functionality that is already built into Twig Requirements ------------ [](#requirements) Closure requires Craft CMS 4.x or 5.x Installation ------------ [](#installation) To install Closure, follow these steps: 1. Open your terminal and go to your Craft project: ``` cd /path/to/project ``` 2. Then tell Composer to require the package: ``` composer require nystudio107/craft-closure ``` About Closure ------------- [](#about-closure) Twig supports arrow function closures, but only in the [filter](https://twig.symfony.com/doc/3.x/filters/filter.html), [map](https://twig.symfony.com/doc/3.x/filters/map.html), and [reduce](https://twig.symfony.com/doc/3.x/filters/reduce.html) filters. Twig unfortunately [has no plans](https://github.com/twigphp/Twig/issues/3402) to allow for more widespread usage of arrow function closures. Craft Closure allows you to use arrow function closures anywhere, which is especially useful with [Laravel Collection methods](https://laravel.com/docs/9.x/collections#available-methods), many of which take a closure as a parameter. Using Closure ------------- [](#using-closure) Once you've added the `nystudio107/craft-closure` package to your project, no further setup is needed. This is because it operates as an auto-bootstrapping Yii2 Module. You can then pass an [arrow function](https://timkelty.github.io/twig-tips/10-arrow-fn.html) closure as a parameter to anything that accepts them, such as many [Laravel Collection methods](https://laravel.com/docs/9.x/collections#available-methods): ``` {% set collection = collect(['a', 'b', 'c']) %} {% set contains = collection.contains((value, key) => value == 'z') %} ``` Or you can assign an arrow function closure to a Twig variable for re-use: ``` {% set collection = collect(['a', 'b', 'c']) %} {% set closure = (value, key) => value == 'a' %} {% set contains = collection.contains(closure) %} ``` Using arrow function closures especially useful now that Craft element queries can all return a Collection via the [.collect()](https://docs.craftcms.com/api/v4/craft-db-query.html#method-collect) method.
