# Deprecation: #100047 - Deprecated ConditionMatcher classes {#deprecation-100047-1677607925}

See [forge#100047](https://forge.typo3.org/issues/100047)

## Description {#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 {#impact}

The TYPO3 Core only uses these classes within the old TypoScript parser classes,
which have been [deprecated](https://docs.typo3.org/permalink/changelog:deprecation-99120-1670428555) as well.
Using the classes will trigger a deprecation level log entry.

## Affected installations {#affected-installations}

There was probably little need to implement new variants of the above classes as
the underlying `ExpressionLanguage` construct has its own API to add new
variables and functions for this TypoScript condition related to Symfony expression
language usage.

## Migration {#migration}

No direct migration possible. These classes have been merged into the new
TypoScript parser approach, specifically for 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`.
