Settings::getFullTypoScriptFromConfigurationManager() 

\nn\t3::Settings()->getFullTypoScriptFromConfigurationManager(); 

Get complete TypoScript via the Configuration Manager.

A simple wrapper for the core function but with try { ... } catch() Fallback.

Returns the notation with dots. This can be done via | \nn\t3::TypoScript()->convertToPlainArray() into a normal array be converted into a normal array.

// ==> ['plugin.']['example.'][...]
$setup = \nn\t3::Settings()->getFullTypoScriptFromConfigurationManager();
