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()

Formatting

  • Indentation: 2 spaces (4 for Go files)
  • Line length: 140 characters max
  • Braces: else/catch/finally on new lines
  • Only in /rustrover directory you must always use standard Kotlin formatting rules with 4 spaces indentation.
