YAML Config
YAML Config is a configuration library that lets mod developers define and manage settings in the YAML file format, with a GUI for editing them.
What it does
Developers use the library to create configuration files written in YAML, a format chosen for its readability. Players can open a graphical screen to browse and change those settings without editing text files by hand. The library handles reading and writing the files, so a mod built on it does not need its own parser.
Supported values include the primitive types boolean, int, float, double and String, along with ResourceLocation and Registry entries, collections such as List and Map, and LocalDateTime for dates and times. When a setting is changed on a server, the new value is pushed to connected clients so both sides stay in step. The library is a dependency rather than a standalone feature: it is required by 6 other mods, including Arc Lib, Item Restrictions, Jobs+, GriefLogger and Tiny Mob Farm Remastered. It is published for Fabric and NeoForge across 13 release versions, 1.21 – 26.3, and the code is under the Apache License 2.0, so it is open source.
Key features

Configuration values are written as YAML text, which keeps the stored settings legible to people reading the file.
Graphical settings screen
A screen lists configuration entries so players can view and adjust values without opening a text editor.
Typed configuration values
Primitive values, registry identifiers, lists, maps and date-time values can all be stored as configuration entries.

Use cases
Mod configuration
A mod author can declare its options once and let players change them in a screen instead of a text file.
Server administration
Server owners can adjust mod settings in one place and have clients receive the updated values.
Who it’s for: Mod developers who want a YAML-based configuration system with a graphical editor, and server owners who manage configuration for several mods.
