# Kotlin Kotlin language support in Zed is provided by the community-maintained [Kotlin extension](https://github.com/zed-extensions/kotlin). Report issues to: [https://github.com/zed-extensions/kotlin/issues](https://github.com/zed-extensions/kotlin/issues) - Tree-sitter: [fwcd/tree-sitter-kotlin](https://github.com/fwcd/tree-sitter-kotlin) - Language Server: [fwcd/kotlin-language-server](https://github.com/fwcd/kotlin-language-server) ## Configuration Workspace configuration options can be passed to the language server via lsp settings in `settings.json`. The following example changes the JVM target from `default` (which is 1.8) to `17`: ```json { "lsp": { "kotlin-language-server": { "settings": { "compiler": { "jvm": { "target": "17" } } } } } } ``` The full list of workspace configuration options can be found [here](https://github.com/fwcd/kotlin-language-server/blob/main/server/src/main/kotlin/org/javacs/kt/Configuration.kt).
