KSP 範例

取得所有成員函式​

fun KSClassDeclaration.getDeclaredFunctions(): Sequence<KSFunctionDeclaration> =
    declarations.filterIsInstance<KSFunctionDeclaration>()

檢查類別或函式是否為本地（Local）​

fun KSDeclaration.isLocal(): Boolean =
    parentDeclaration != null && parentDeclaration !is KSClassDeclaration

尋找類型別名指向的實際類別或介面宣告​

fun KSTypeAlias.findActualType(): KSClassDeclaration {
    val resolvedType = this.type.resolve().declaration
    return if (resolvedType is KSTypeAlias) {
        resolvedType.findActualType()
    } else {
        resolvedType as KSClassDeclaration
    }
}

收集檔案註解中被抑制的名稱（Suppressed Names）​

// @file:kotlin.Suppress("Example1", "Example2")
fun KSFile.suppressedNames(): Sequence<String> = annotations
    .filter {
        it.shortName.asString() == "Suppress" &&
        it.annotationType.resolve().declaration.qualifiedName?.asString() == "kotlin.Suppress"
    }.flatMap {
        it.arguments.flatMap {
            (it.value as Array<String>).toList()
        }
    }
