Question: recipes and tags reflection

[Adirelle]

Say I would like to add recipes to turn all slabs into blocks.

For example, for cobblestone, I would add this recipe:

{
    "type": "crafting_shaped",
    "pattern": [
        "S",
        "S"
    ],
    "key": {
        "S": {
            "item": "minecraft:cobblestone_slab"
        }
    },
    "result": {
        "item": "minecraft:cobblestone"
    }
}

Now, what I really want is a way to automate these recipes creating at loading to support all vanilla and third-party slabs, e.g.:

• for each slab item S (for example all items in the "minecraft:slabs" item tag):
  • find the "crafting_shaped" recipe to create 6 items S,
  • analyze the recipe to find the ingredient I,
  • add a shaped recipe to create 1 I from 2 S.

Does KubeJS support things like "iterating over all items of a tag", "finding a recipe by its result", etc. ?

Edit: removed reference to stairs, as it the same problem, just with different items.
