Zine

Zine bundles helper code that other mod developers can call instead of writing their own. Its RegistryHelper class offers methods for registering content, and RegistryQueue holds registration values until they are needed. DataHelper reads and writes data through byte buffers and mutable objects, and RegistryCodecGroup groups related codecs for dynamic registries.

Data generation support comes from a particle texture provider and a sound list provider, the latter written before Fabric API added its own. The Modify Advancement event lets a mod change existing vanilla advancements, and the VanillaAdvancementModifications class covers simple edits such as adding a food requirement to the Balanced Diet advancement. Fabric API is required, and the mod is built for Fabric only.

Zine runs on client and server, so both the server and every player need it. Files cover 1.21.5 – 26.3 across 12 release versions, with 1.12.0 for 26.3 as the latest. Only the source code is public, and the mod is not open source; it is released under All rights reserved. The author notes that the whole library may change without warning, so it suits projects that accept that risk.
