Getting the resources required for carft

[SLywnow]

Is there an easy way to get all the initial resources that are required for crafting? Not "iron plate" or "battery", and how much iron, oil, etc needed for crafting? Or can I only find them after 1000 "for"? I only need to get the original resources, which are written, as an example, in creative mode, instead of ingredients.
And I need to get it in data.lua, not in scripts

Recursive script like:
1. All raw resources
2. All items, that use 1. resources
3. All items, that use items from 2.
Etc.

By every iteration write previous resource items and amounts of them.

Some of the big modpacks are very likely to have infinite loops to convert between (waste) products and production chains. A simple example: (H2O) -> (H + 2O) -> (H2O). And no, there is no easy way. You should tell what problem you're actually trying to solve. If you just want to assign a "score" to each item look at the team production scenario.
