Scalar is a Scala language provider for Cleanroom. It provides Scala 2.11 library for legacy Forge mods.

In 1.12.2, Forge ships a set of seriously outdated Scala libraries. These libraries are removed in Cleanroomm and bundled into this independent mod.

To run legacy mods developed in Scala (OpenComputer, ProjectRed) on Cleanroom, this mod is necessary.

FAQ:

Q: What is Cleanroom?
A: Cleanroom is a 1.12.2 Forge fork, providing faster launch speed, newer toolchain, new APIs and 99% compatibility. Our plan is to make 1.12.2 up-to-date with latest toolchain while adding more feature to Forge & vanilla, so we don't need to care about higher versions' X point release * Y Mod API headache.
Q: How to install Cleanroom?
A: Please follow the instructions in README.
Q: Can I include this in my Forge modpack? Will it crash my Forge pack?
A: Yes, you can, and it is safe! This mod won't be loaded or crash anything in a Forge environment.
Q: Why make another project?
A: Putting Scala 3 provider and Scala 2 provider in same project keep producing confusion and unnecessary crash reports.
Q: Why not just include Scala in the loader?
A: Scala 2.11 is deprecated and can't be compiled against under Java 21+. Our goal is not only providing a runtime but also latest development toolchain, so switching to Scala 3 is important. Make Scala become standalone mods is the only solution here.

Note: mod files marked as "Forge" because CurseForge doesn't support Cleanroom yet.
