KSP examples

Get all member functions that are declared directly within a class:

fun KSClassDeclaration.getDeclaredFunctions(): List<KSFunctionDeclaration> { return this.declarations.filterIsInstance<KSFunctionDeclaration>() } 

Determine whether a class or function is local to another function:

fun KSDeclaration.isLocal(): Boolean { return this.parentDeclaration != null && this.parentDeclaration !is KSClassDeclaration } 

Find the actual class or interface declaration that the alias points to recursively:

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

Find out suppressed names in a file annotation:

// @file:kotlin.Suppress("Example1", "Example2") fun KSFile.suppressedNames(): List<String> { val ignoredNames = mutableListOf<String>() annotations.forEach { if (it.shortName.asString() == "Suppress" && it.annotationType.resolve()?.declaration?.qualifiedName?.asString() == "kotlin.Suppress") { it.arguments.forEach { (it.value as List<String>).forEach { ignoredNames.add(it) } } } } return ignoredNames }
