Silverstripe CMS 6 polyfill for CMS 5
=====================================

[](#silverstripe-cms-6-polyfill-for-cms-5)

Silverstripe CMS 6 moved a bunch of classes around. e.g.: `SilverStripe\ORM\ArrayList` got moved to `SilverStripe\Model\List\ArrayList`.

So in CMS 5, many classes will now throw deprecation warning about the class being moved to a different namespace. However, since these new classes don't exist yet, you can't fix the deprecation warning without upgrading to CMS 6.

```
public function __construct(array $items = [])
{
    Deprecation::withSuppressedNotice(function () {
        Deprecation::notice('5.4.0', 'Will be renamed to SilverStripe\Model\List\ArrayList', Deprecation::SCOPE_CLASS);
    });

    $this->items = array_values($items ?? []);
    parent::__construct();
}
```

This packages ships copies of the current CMS 5 classes but moved to their CMS 6 namespace. It removes the deprecation warning from the constructor, that way you can adopt the new namespace in CMS 5.

Using this module
-----------------

1. Install the module to your project.

```
composer run archiprocode/silverstripe-six-poylfill
