Signalled by by cache versions of parser wrapper functions inc/parserutils.php. Syntax plugins can use this event to provide their own assistance to DokuWiki's cache validity logic when the syntax extension adds other dependencies to the rendered page.

$data is a cache object – refer inc/cache.php.

For handling the event, key properties of the cache object are:

• page, if present the wiki page id, may not always be present, e.g. when called for locale XHTML files
• file, source file
• mode, renderer mode (e.g. 'XHTML') or 'i' for instructions
• depends, array of dependencies used to determine cache validity

The following plugins are known to handle this event and their source code may be a good start for understanding and implementing a handler yourself.

• include
• indexmenu

• Action Plugins
• Events
