ModifyLanguagePacksEvent
New in version 12.2
The PSR-14 event \TYPO3\
allows to ignore extensions or individual language packs for extensions when
downloading language packs.
The options of the language: command can be used to further
restrict the download (ignore additional extensions or download only certain
languages), but not to ignore decisions made by the event.
Example
<?php
declare(strict_types=1);
namespace MyVendor\MyExtension\Install\EventListener;
use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Install\Service\Event\ModifyLanguagePacksEvent;
#[AsEventListener(
identifier: 'my-extension/modify-language-packs',
)]
final readonly class MyEventListener
{
public function __invoke(ModifyLanguagePacksEvent $event): void
{
$extensions = $event->getExtensions();
foreach ($extensions as $key => $extension) {
// Do not download language packs from Core extensions
if ($extension['type'] === 'typo3-cms-framework') {
$event->removeExtension($key);
}
}
// Remove German language pack from EXT:styleguide
$event->removeIsoFromExtension('de', 'styleguide');
}
}
New in version 13.0
The PHP attribute \TYPO3\ has been
introduced to tag a PHP class as an event listener. Alternatively, or if you
need to be compatible with older TYPO3 versions, you can also register an
event listener via the Configuration/ file. Switch to
an older version of this page for an example or have a look at the section
Implementing an event listener in your extension.
