I'm seeing a strange problem with this:

fun gitComplete(line: String, cursorIndex: Int): List<String> {
    val words = line.split(" ")
    if (words[0] == "git") return listOf("commit", "status")
            else return emptyList()
}

val result = if (args.size == 2) gitComplete(args[0], args[1].toInt())
    else emptyList()

result

The script above returns a valid result (a list of strings), but if I remove the intermediate result variable:

fun gitComplete(line: String, cursorIndex: Int): List<String> {
    val words = line.split(" ")
    if (words[0] == "git") return listOf("commit", "status")
            else return emptyList()
}

if (args.size == 2) gitComplete(args[0], args[1].toInt())
    else emptyList()

then the result of the evaluation by the engine is null.

This is expected behavior. Script result is the result of the last expression or statement, but the result of statement has type Unit. In JSR-223 settings it is conveyed via null.

Sure but the result of the last expression in the second example is the same as in the first example

Ah, sorry, missed this part. Will try to check it.

I reproduced it, will work on a fix.
