Requires Iskandert's Utilities 3.3.0.0.0 or newer.

Datapack-driven processing machine (iska_utils:factory): one input stack, player-selected output variant, optional RF/FE per operation. Can also act as an alternative Stonecutter for vanilla minecraft:stonecutting recipes (runtime lookup; not datapack rows).

data/<namespace>/recipe/<any-subfolder>/<name>.json

Required root field (canonical):

"type": "iska_utils:factory"

The mod registers a real Minecraft RecipeType / serializer (iska_utils:factory). Bundle files with a recipes (or legacy sources) array are split by Iskandert's Library into one RecipeManager entry per row before KubeJS/CraftTweaker see them, so each mapping has its own recipe id and can be removed/overridden natively.

• Bundle still allowed: keep several rows in one JSON; Library expands them at load.
• Child ids: always namespace:path_N (continuous array index: _0, _1, …). Optional row "id" stays as JSON metadata only and is not used in the ResourceLocation.
• KubeJS mirrors: after split, each child gets injected results / ingredients (from select / input) plus datapack kubejs/recipe_schema so generic filters work. Prefer those over relying on a single getResultItem().
• KubeJS examples:
  • event.remove({ id: 'iska_utils:factory/factory_sources_0' })
  • event.remove({ output: 'iska_utils:drop_of_entropy' })
  • event.replaceOutput({ type: 'iska_utils:factory' }, 'minecraft:white_dye', 'minecraft:blue_dye')
  • override / add via datapack or event.custom
• Single-entry files: a flat JSON (no recipes array) with input / select is also valid (mirrors injected in place).

Mod convention: data/iska_utils/recipe/factory/ (mappings + shaped crafting for the block).

Reload: /reload or /iska_lib_dev reload.

Output ids that are not registered (e.g. optional mod compat) are skipped at load time; the row is kept if at least one output remains.

Requires Iskandert's Utilities 3.5.0.0.0 or newer.

A) Flat AND / OR — optional mods / stages on the recipe row or on individual select[] entries (per-output gate).

B) DEF_AND / DEF_OR — indexed stages[] / mods[] on the row + top-level if[]. Each branch payload is { "select": [ … ] }. First matching branch supplies the output grid, craft tick, and JEI. select[] flat and if[] on the same row are mutually exclusive (parse warning if both present).

No branch satisfied → input still matches the row but no output variant (empty GUI grid, no craft).

Ancient Table owner: same rules as Ancient Tablet gates — first GUI open assigns owner for automated craft; owner cleared on break.

JEI: shows select[] from the active DEF branch (or flat list); dynamic refresh on JEI / Factory GUI open. Missing mod → row hidden.

Older packs may use "type": "iska_utils:factory_sources" with a sources array and colors entries using "id" instead of "output". Prefer iska_utils:factory + recipes + select for new datapacks.

• Slots: input + output (auto-crafts while input matches a mapping, output has space, and redstone allows).
• Output choice: scroll/select in GUI; last choice per input mapping is remembered.
• Redstone modes (GUI): none / low / high / pulse (one op per rising edge) / disabled.
• Energy: optional RF/FE buffer; when buffer size is 0 in server config, energy is not used.

When enabled in server config (see dev below), the Factory accepts any input that has a vanilla stonecutter recipe (minecraft:stonecutting), if no iska_utils:factory mapping matches first.

• Priority: datapack iska_utils:factory mappings are checked first; stonecutter is a fallback only.
• GUI: same output grid as custom mappings — all stonecutter results for that input appear as selectable variants (1 input item per operation).
• Energy: stonecutter-style operations use 005_factory_stonecutter_energy_per_operation (default 5 RF/op) when the Factory energy buffer is enabled (303_factoryEnergyBuffer > 0). Datapack rows still use each recipe’s energy_per_operation.
• JEI: stonecutter recipes are not listed in the mod Factory JEI category (jei.iska_utils.factory). They stay in vanilla Stonecutter JEI. When 004_factory_stonecutter_enabled is true, the Factory block is also registered as a crafting station for that Stonecutter category (alongside minecraft:stonecutter), so players can see the Factory as an alternative workstation there.

When 004_factory_stonecutter_enabled is false, the Factory only accepts inputs defined by iska_utils:factory datapacks.

Default mappings: data/iska_utils/recipe/factory/factory_sources.json (dye berry → dyes, delivery recycle tag → drop of entropy).

Block crafting (shaped): data/iska_utils/recipe/factory/factory.json — normal minecraft:crafting_shaped, not iska_utils:factory.

Category jei.iska_utils.factory: representative input stack(s) and a 9×3 output grid (up to 27 outputs per page; extra pages when a mapping has more variants). Tag inputs expand to all tag members in JEI. Only datapack iska_utils:factory mappings — not stonecutter fallback recipes.

Stonecutter category (vanilla JEI): shows every minecraft:stonecutting recipe. With stonecutter mode enabled, the Factory item appears as an additional crafting station for that category (see Stonecutter compatibility above). Datapack Factory mappings never duplicate into the Stonecutter list.

If two mappings accept the same input item, the first loaded mapping wins (findSource scan order).
