Quilt Standard Libraries (QSL)

Essential standard libraries for the Quilt ecosystem.

The Quilt Standard Libraries gives modders Quilt-exclusive tools to add new and exciting features to their mods.

Note: At the moment, the Quilt Standard Libraries are in beta, meaning issues may arise and should still be treated as experimental. Please make an issue or talk to the QSL team on discord or on the forum before writing any PRs.

Repository structure

The repository has 2 main parts:

• The library folder. This contains all the libraries that are part of the Quilt Standard Libraries.
• The build-logic folder. This is an included build in Gradle and contains most of the buildscript used inside the libraries. This keeps the buildscripts inside the library folder as minimal as possible; definitions of data rather than logic.

Features

Here are multiple charts of features available in QSL which also serves as a comparison chart with Fabric API.

The charts are organized by QSL libraries.
