Hexpose

Hexpose is a library addon for Hex Casting. It adds scrying patterns that report information about entities, blocks and containers, and it defines new iota types that other addons can pass between spells. Text iotas hold strings, including Minecraft text formatting, and item stack iotas hold the contents of an item, which lets other addons read and process item data through one interface. MoreIotas is also required, and the mod depends on Hex Casting to provide the casting system.

The identifier iota represents a resource name such as minecraft:diamond. Spells can use it for type checks on items, blocks, entities, dimensions and villager types. Hexpose also adds particle and sound handling that other addons rely on. Because it only serves as a library, the mod has no effect on its own, and it does nothing until another addon or a spell uses its patterns.

Both sides need the mod, since clients and servers run it together. Files are published for Fabric and Quilt on 1.20.1 only, with 3.0.0 for Fabric and 2.0.0 for Quilt as the latest builds.
