Oracle Index
by rearth
Oracle Index is a client-side documentation viewer for Fabric and NeoForge that displays plain text pages organized like a ModdedMC.wiki site.
What it does
Pages are plain text files placed in a folder structure that mirrors the ModdedMC.wiki layout, and the mod reads them on the client. The exact folder is set in the mod's configuration. Content can be supplied through a mod's resources or through a resource pack, and the project's GitHub repository includes an example pack.
The viewer opens from a hotkey the player can change, or from an item's tooltip, so reference text can sit next to the item it describes. Parsing is basic, and custom HTML tags are accepted so that wiki content written for ModdedMC.wiki displays without edits. Architectury API must be installed alongside the mod on both loaders. Oracle Index is published for 1.21, 1.21.1 and 26.1.2, and the latest Fabric and NeoForge files are version 2.0.0 for 26.1.2, released 2026-09-14. The code is licensed under Creative Commons Attribution 4.0, so the project is not open source.
Key features
Hotkey and tooltip access
A configurable key opens the viewer, and an item's tooltip can open the page written for that item.
Semantic search
Built-in search matches the meaning of a query rather than only exact words, and it evaluates math expressions typed into the search box.
Wiki-style content and HTML
A basic parser renders pages, and custom HTML tags are supported for wiki-style content.
Cross-linking
Links move between pages and between items, so a reader can follow references across the wiki.
Responsive layout
The interface uses a Minecraft-inspired style, smooth scrolling and layouts that resize to the screen.
