RegistryLib

RegistryLib is a fluent registration library for NeoForge that consolidates item, block, fluid, block entity, and datagen registration into a single builder chain.

REGISTRYLIB.item("copper_coin", Item::new)
    .lang("Copper Coin")
    .defaultModel()
    .addDefaultTab()
    .register();

One chain. One place. Everything registered.

Why RegistryLib?

Without RegistryLib	With RegistryLib
Separate DeferredRegister calls for each registry	One RegistryCore entry point
Manual DataProvider registration for lang, models, loot, tags	Datagen integrated into the builder chain
Scattered boilerplate across multiple classes	Everything in one fluent chain
Easy to forget a step (missing model, lang, creative tab—	Builder guides you through all common configuration

I'm new to RegistryLib

Start with the beginner tutorials —they'll get you from zero to a working item in 5 minutes:

1. Installation & Setup —Add the dependency and create your RegistryCore
2. Your First Item —Register a simple item
3. Your First Block —Register a block with a BlockItem
4. Understanding the Chain —How the fluent API works

I know the basics, show me more

Jump into intermediate tutorials for real-world patterns:

• Group System —Share defaults across entries
• Tooltip System —Multi-section tooltips
• Multi-Language Support —Add extra locales
• Recipes and Tags —Datagen integration

I need to do something specific

How-to guides are task-focused references:

• Register Items | Register Blocks | Register Fluids
• Register Block Entities | Register Advancements

I need API details

Reference pages provide lookup tables and method signatures:
