README

The package provides some Symfony resources for bundles that want to be compatible with both Symfony 4 and 5:

What's inside?

InputBag

The InputBag class was added to the HttpFoundation component in Symfony 5. The polyfill will save you a lot of if (class_exists(InputBag:class)) checks by providing the InputBag class in Symfony 4 as well.

TranslatorInterface

The TranslatorInterface has been moved from the Translation component to the Contracts component in Symfony 5. The polyfill restores the old interface in Symfony 5.

Scope

If you want your Contao extension to be compatible with multiple Contao versions (e.g. 4.9 to 4.13), you will also have to be compatible with both Symfony 4 and 5. Require the polyfill in your composer.json in this case.

License

Contao is licensed under the terms of the LGPLv3.
