=====================================
AfterTemplatesHaveBeenDeterminedEvent
=====================================

..  versionadded:: 12.0
    This event is a substitution for the
    :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['Core/TypoScript/TemplateService']['runThroughTemplatesPostProcessing']`
    hook.

The PSR-14 event
:php:`\TYPO3\CMS\Core\TypoScript\IncludeTree\Event\AfterTemplatesHaveBeenDeterminedEvent`
can be used to manipulate :sql:`sys_template` rows. The event receives the list
of resolved :sql:`sys_template` rows and the
:php:`\Psr\Http\Message\ServerRequestInterface` and allows manipulating the
:sql:`sys_template` rows array.

The event is called in the code of the :guilabel:`Site Management > TypoScript`
backend module, for example in the submodule :guilabel:`Included TypoScript`,
and in the frontend.

Extensions using the old hook that want to stay compatible with TYPO3 v11
and v12 can implement both the hook and the event.
