# KotlinLangForge<\/p>\n
> Provides a Kotlin language adapter for Forge and Neoforge<\/p>\n
This mod adds a language adapter for Kotlin and provides multiple libraries.<\/p>\n
## Developer usage<\/p>\n
To add your language adapter to your mod, add the following lines to your
\n(neoforge.)mods.toml.<\/p>\n
**neoforge.mods.toml**<\/p>\n
“`toml
\nmodLoader = “klf”
\nloaderVersion = “1,)”
\n“`<\/p>\n
Now you can init your mod like any other.
\nJust make sure your `@Mod` class is either an object or a class with a public constructor.
\nThe constructor can take the following four arguments (they should never duplicate):<\/p>\n
– IEventBus
\n– ModContainer
\n– KotlinModContainer
\n– Dist<\/p>\n
If you want to implement the libraries in your mod, import the following dependency,
\nmatching the language provider version, your loader and the (latest) version of Kotlin.<\/p>\n
**Versioning**<\/p>\n
The “language provider version” is a version only provided by KotlinLangForge.
\nThis format is not used by Forge or NeoForge and only serves as a simple differentiation variable between the different
\nlanguage provider implementations over the course of the versions of Minecraft.<\/p>\n
| version of Minecraft | language provider version | supported loaders |
\n|———————-|—————————|——————-|
\n| 1.16.5 | 1.0 | Forge |
\n| 1.17.1 – 1.20.4 | 2.0 | Forge, NeoForge |
\n| 1.20.5 – 1.21.8 | 3.0 | NeoForge |
\n| 1.21.9 – 26.x | 3.1 | NeoForge |<\/p>\n

*For lp: <=3.0, you will have to use `modImplementation`.*\n\n### Events\n\nTo use automatic event listener registration, the `@EventBusSubscriber` annotation has to be added on the class\/file.\nKlf then will automatically find all methods that have events in their parameters and will determine which event bus to\nuse.\nAdditionally, you can annotate a method with `@SubscribeEvent` to adjust the listener's parameters.\n\n**Note for Forge developers:** Private event listeners cannot be processed on Forge and will result in a crash!\n\n**Mod Bus:** The mod bus is available via the top-level declaration `dev.nyon.klf.MOD_BUS`.\n\n## Included Libraries\n\n- org.jetbrains.kotlin:kotlin-stdlib:2.3.21\n- org.jetbrains.kotlin:kotlin-stdlib-jdk8:2.3.21\n- org.jetbrains.kotlin:kotlin-stdlib-jdk7:2.3.21\n- org.jetbrains.kotlin:kotlin-reflect:2.3.21\n- org.jetbrains.kotlinx:kotlinx-serialization-core:1.9.0\n- org.jetbrains.kotlinx:kotlinx-serialization-json:1.9.0\n- org.jetbrains.kotlinx:kotlinx-serialization-cbor:1.9.0\n- org.jetbrains.kotlinx:kotlinx-coroutines-core:1.10.2\n- org.jetbrains.kotlinx:kotlinx-coroutines-jdk8:1.10.2\n- org.jetbrains.kotlinx:kotlinx-datetime:0.7.1-0.6.x-compat\n- org.jetbrains.kotlinx:kotlinx-io-core:0.8.0\n- org.jetbrains.kotlinx:kotlinx-io-bytestring:0.8.0\n- org.jetbrains.kotlinx:atomicfu:0.29.0\n\n### Other\n\nIf you need help with any of my mods, just join my [discord server.\n<\/p>\n","protected":false},"excerpt":{"rendered":"
