Deprecation: #100047 - Deprecated ConditionMatcher classes¶

Description¶

The following classes have been marked as deprecated in TYPO3 v12 and will be removed with v13:

\TYPO3\CMS\Core\Configuration\TypoScript\ConditionMatching\ConditionMatcherInterface
\TYPO3\CMS\Core\Configuration\TypoScript\ConditionMatching\AbstractConditionMatcher
\TYPO3\CMS\Backend\Configuration\TypoScript\ConditionMatching\ConditionMatcher
\TYPO3\CMS\Frontend\Configuration\TypoScript\ConditionMatching\ConditionMatcher

Impact¶

The TYPO3 core only uses these classes within the old TypoScript parser classes, which have been deprecated as well. Using the classes will trigger a deprecation level log entry.

Affected installations¶

There was most likely little need do implement own variants of the above classes, the underlying ExpressionLanguage construct has an own API to add own variables and functions for this TypoScript condition related symfony expression language usage.

Migration¶

No direct migration possible. These classes have been merged into the new TypoScript parser approach, specifically to class \TYPO3\CMS\Core\TypoScript\IncludeTree\Visitor\IncludeTreeConditionMatcherVisitor.

Adding TypoScript related expression language variables and functions should be done using \TYPO3\CMS\Core\ExpressionLanguage\ProviderInterface.
