I'm not sure on the proper syntax to get this to work. The error is that a suspend function can only be ran inside a coroutine scope. How do I make "runSomething" be a coroutine scope which is one the launch inside starts?

runSomething {
someSuspendFunction()
}

fun runSomething(action: () -> Unit) {
viewModelScope.launch {
try {
busy=true
action()
}
finally {
busy=false
}
}
}

declare your action as suspend () -> Unit, i.e. a suspend lambda

[Andrew]

Thanks, that worked

Or make your function runSomething be an inline function.

[octylFractal]

that seems like the wrong thing to do here since it's using launch and not calling it directly. inline would technically work if runSomething was called in a suspend context, but if it's not it prevents legitimate calls that could use the suspend context in launch

[streetsofboston]

You're right. Looking at it again, making the function inline would probably need to have its action lamba param to be declared noinline, which would defeat the purpose.
