Code Style

Follow the IntelliJ Coding Guidelines with these IntelliJ-specific rules.

Language

• ALWAYS use Kotlin for new files - Only use Java when modifying existing Java code
• Use idiomatic Kotlin: extension functions, data classes, null safety
• Mark experimental APIs with @ApiStatus.Experimental
• Build scripts Kotlin style: Follow community/platform/build-scripts/kotlin-style-recommendations.md for build-scripts code:
  • Use @JvmField for internal data class fields
  • Use .put()/.get() instead of [] operator
  • Use explicit HashMap/HashSet/LinkedHashMap instead of mutableMapOf()/mutableSetOf()
