hey folks,

i'm working on migrating some PSI code from K1 to K2.

The usecase is this:

fun foo() {
  GlobalScope.launch {
    // anonymous suspend function <===
    try {
      delay(1_000)
    } catch (_: Exception) {
      // general error handling
    }
  }
}

I need to be able to tell if the try-block is running within a suspend function (as is this case).

I have this so far:

// visitTryExpression
val function = expression.getParentOfType<KtFunction>(strict = true) ?: return
analyze(function) {
  val symbol: KaAnonymousFunctionSymbol = function.symbol
  // symbol.isSuspend does not exist
}

I noticed that KaAnonymousFunctionSymbol.isSuspend does not exist, even though KaNamedFunctionSymbol.isSuspend exists.

My question is: how does one get whether an anonymous function/lambda is a suspend function in the analysis API?e

Hi! Unfortunately there’s no easy “built-in” way to do the thing that you want to do via Analysis API

Let me share some utilities with you which we use internally to solve the same task
