About this Mod

A general utility, GUI and config library for modding on Fabric and Quilt
Features include:
owo-ui, a fully-featured declarative UI library for building dynamic, beautiful screens with blazingly fast development times
owo-config, a built-in, customizable configuration system built on top of owo-ui. It provides many of the same features as Cloth Config while many new conveniences, like server-client config synchronization, added on top
A fully automatic registration system that is designed to be as generic as possible. It is simple and non-verbose to use for basic registries, yet the underlying API tree is flexible and can also be used for many custom registration solutions
Item Group extensions which allow for sub-tabs inside your mod's group as well as a host of other features like custom buttons, textures and item variant handling
A fully-featured networking layer with fully automatic serialization, handshaking to ensure client compatibility and a built-in solution for triggering parametrized particle events in a side-agnostic manner
Client-sided particle helpers that allow for easily composing multi-particle effects
Rich text translations, allowing you to use Minecraft's text component format in your language files to provide styled text without any code
owo is documented in two main ways:
- There is rich, detailed JavaDoc throughout the entire codebase
- There is a wiki with in-depth explanations and tutorials for most of owo's features over at https://docs.wispforest.io/owo/features
