Fireplace Lib
Fireplace Lib is a library mod that holds common functionality other mods can share, so code is kept in one place rather than copied between projects.
What it does
Fireplace Lib collects shared code for mods by The-Fireplace: multithreading helpers, JSON serialization for saving and loading data, and common pieces used by commands, config screens and GUIs. Because this logic lives in one library, a fix made once reaches every mod that depends on it, and developers can switch to a corrected version quickly. The library itself is light: it shows up in the mod list and adds no content for players to see.
The mod is published for Fabric, Forge and Quilt across 37 game versions, 1.14.4 – 1.21.11. Either side can run it, and neither needs it. Required dependencies are Annotated DI and Fabric API on Fabric, and Annotated DI is bundled inside the mod. Cloth Config API and Mod Menu are optional. The code is open source under the MIT License, and the source, issue tracker and wiki are public.
Key features
Shared common code
Commands, config screens and GUIs draw on common functionality kept in one library instead of duplicated in each mod.
Multithreading helpers
Helpers let a task run in parallel so more work completes in a single pass.
JSON serialization
Data is serialized to and from the JSON format, which makes saving and loading data simpler.
Translation management
Translations are handled centrally, so a server can use a language different from the one players set on their clients.
