Item Alchemy Expansion
by luckfun233
Item Alchemy Expansion is a Fabric add-on for Item Alchemy that lets the Transmutation Table recognize NBT data on items, shulker boxes included.
What it does
The add-on requires Item Alchemy and mcpitanlib 3.3.2 or later, and it needs Fabric API as well. Once installed, the Transmutation Table treats items with different NBT data as distinct, so a stored enchanted or named item is no longer priced the same as a plain one. Shulker box contents are handled too, and a shift preview shows the 9×3 contents of a box when the player holds Shift while hovering over it.
Price handling covers crafting, smelting and other recipes, including custom recipe types defined by other mods. Items without a defined EMC value get one by summing the EMC of their materials. The configuration screen is available through Mod Menu under the Item Alchemy Expansion Experimental category and uses Cloth Config, which lets server owners set display styles and strategies. A confirmation dialog appears the first time the feature is enabled and lists items with manually set EMC values, so the user can keep those values or hand them over to automatic pricing. Potions stored in the table no longer turn into Uncraftable Potions after retrieval.
Installation covers the server and each player's game. It is released under the MIT License and the source code is public. Items that were already in the table without NBT, such as those from the Uncraftable Potions mod, have to be placed in the table again after installation for the fix to apply. Bugs and feature suggestions go to GitHub Issues.
Key features
NBT-aware Transmutation Table
The table distinguishes items by their NBT data, so differently stored items get their own values.
Shulker box preview
Holding Shift over a shulker box displays its nine-by-three contents, and WASD or arrow keys move focus between items.
Automatic price calculation
Recipes from crafting, smelting and mod-defined types are scanned to calculate prices for items without a set EMC value.
Manual EMC check dialog
On first enable, items with manually set EMC values are listed so the user can keep them or switch to automatic pricing.
Batch repricing command
The itemalchemy-expansion reprice command reruns batch pricing if the user accidentally chooses to keep manual values.
