GTNH's Forgelin
by mitchej123
GTNH's Forgelin is a library mod for Forge 1.7.10 that lets other mods be written in Kotlin.
What it does
Forgelin supplies a Forge language adapter, so a Kotlin object class can act as the main class of a mod. Other mods rely on it for the Kotlin standard library and its companion libraries, which Forgelin packs into its own jar instead of requiring each dependent mod to carry them. Forgelin adds no content of its own. Other mods in a modlist require it to be installed. A server running it needs every connecting player to have it too. Its license is the GNU Lesser General Public License v3.0 only, and the project is open source.
