========================
ModifyLanguagePacksEvent
========================

..  versionadded:: 12.2

The PSR-14 event :php:`\TYPO3\CMS\Install\Service\Event\ModifyLanguagePacksEvent`
allows to ignore extensions or individual language packs for extensions when
downloading language packs.

The options of the :bash:`language:update` 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
=======

Registration of the event:

..  literalinclude:: _ModifyLanguagePacksEvent/_Services.yaml
