TYPO3 Using data from ViewHelper in Fluid

How can I use data coming from a custom ViewHelper in my Fluid Template.

I have made a custom ViewHelper that is returning data like this:

{cars: {
0: {car:'VW Golf V TDi 140 GT Sport DSG Van',price:'144900'},
1: {car:'Citroën C5 HDi Elegance',price:'168900'},
2: {car:'Seat Leon TSi Stylance',price:'173000'}
}}

And tried the code below, but it doesn't print anything inf the f:for loop. In FLuid I would like to run through this with a f:for loop. But how do I get my data into the f:for syntax?

<f:alias map="<car:CarInfo length="5" />">
  <table cellpadding="5" cellspacing="0" border="2">
    <f:for each="{cars}" as="car">
      <tr>
        <td>{car.car}</td>
        <td>{car.price}</td>
      </tr>
    </f:for>
  </table>
</f:alias>

Does your ViewHelper return an array or a JSON string? If this is a JSON string you cannot consume variables from it without the use of a third party ViewHelper or JSONVariableProvider (Fluid standalone and TYPO3v8+).

See: Parse an existing JSON string in fluid template?

If your ViewHelper does indeed return an array then the most efficient way to solve your use case is:

<f:for each="{car:carInfo(length: 5)}" as="car">...</f:for>

your <f:alias code is broken. you need to use inline annotation, since you want to access the viewhelper inside an other viewhelper https://wiki.typo3.org/Fluid_Inline_Notation

<f:alias map="{cars: '{car:CarInfo(length:\'5\')}'}">

Also did you include your namespace like this?

{namespace car=Vendor\Extension\ViewHelpers}
