Mathematic operations using providers

[Einenlum]

Is there an easy way to do something like :

total_item_price_{1..4}:
    value: <current()> * @offer_price_<current()>->value

Should I create a custom provider? If so, can I resolve values before passing them to my provider?

You can give access to the whole loader to your provider and that way it can fetch what's needed programmatically. That's the best way to achieve complex such tasks I think.

The problem with what you would like to do is that the string <current()> * @offer_price_<current()>->value must, besides being parsed and the value resolved, be evaluated. That's not something that will be added. If you want to do this kind of thing, you should add a custom provider:

total_item_price_{1..4}:
    value: <calculateItemValue(<current()>, @offer_price_<current()>)>
