unflatten-variable-names 

Class: \CPSIT\Typo3Handlebars\DataProcessing\UnflattenVariableNamesProcessor

Converts dot-separated flat variable names into nested arrays. This is useful when other processors set their as key to a dotted path, representing the intended position in a nested data structure.

dataProcessing {
    10 = menu
    10 {
        as = page.nav.mainMenu
    }

    20 = menu
    20 {
        as = page.nav.footerLinks
        special = directory
        special.value = 42
    }

    90 = unflatten-variable-names
}

After processing, the template receives a nested page object:

{{#each page.nav.mainMenu}}
    <a href="{{link}}">{{title}}</a>
{{/each}}

The processor has no configuration properties and operates on the entire processed data array.
