Kotlin Cursor Rules

Kotlin-Specific Rules

Cursor rules in Kotlin provide intelligent navigation and manipulation capabilities designed specifically for Android development with Kotlin. These rules help you work more efficiently with Kotlin's unique features, Jetpack Compose, and Android-specific code.

Code Navigation

• Navigate between class and function definitions
• Jump to Compose composable functions
• Move between coroutine scopes and suspending functions
• Quick access to Android lifecycle methods

Smart Selection

• Select Compose UI blocks and modifiers
• Expand selection to include property delegates
• Smart null-safe operator selection
• Extension function navigation

Code Manipulation

• Quick composable function insertion
• Automated coroutine scope handling
• Android component lifecycle management
• Smart cast and safe call handling

Best Practices

• Use Compose-aware navigation
• Leverage coroutine-specific cursor movements
• Utilize Kotlin's smart cast features
• Navigate efficiently through Android components

Examples

// Navigate between composable functions
@Composable
fun CustomButton(
    text: String,
    onClick: () -> Unit,
    modifier: Modifier = Modifier
) {
    Button(
        onClick = onClick,
        modifier = modifier
    ) {
        Text(text = text)
    }
}

// Smart selection of coroutines and Android lifecycle
class MainViewModel : ViewModel() {
    private val _uiState = MutableStateFlow<UiState>(UiState.Loading)
    val uiState: StateFlow<UiState> = _uiState.asStateFlow()

    fun fetchData() {
        viewModelScope.launch {
            try {
                val result = repository.getData()
                _uiState.value = UiState.Success(result)
            } catch (e: Exception) {
                _uiState.value = UiState.Error(e.message)
            }
        }
    }
}

Configuration

Customize Kotlin-specific cursor rules in your settings:

{
  "kotlin.cursorRules": {
    "composeNavigation": true,
    "coroutineAware": true,
    "androidLifecycle": true,
    "nullSafety": true
  }
}
