Scala Async and Wartremover

Asked 2018-May-24 at 07:27

I wanted to use scala-async. I also use Wartremover with [Return] enabled. (http://www.wartremover.org/doc/warts.html#return).

Then I added some code to test it:

Seems that the async macro generates return statement under the hood.

You can workaround it by adding @SuppressWarnings(Array("org.wartremover.warts.Return")) above the async block.

QUESTION

Throwaway values - what is the best practice in Scala?

Asked 2017-Jun-25 at 13:54

WartRemover's NonUnitStatements requires that statements that aren't returning unit must have an assignment. OK, but sometimes we have to use annoying Java APIs that both mutate and return a value, and we don't actually hardly ever care about the returned value.

So I end up trying this:

My general thoughts about linting tools is that you should not jump through hoops to satisfy them.

The point is to make your code better, both with fewer bugs and stylistically. But just assigning to var _ = does not achieve this. I would first be sure I really really don't care about the return value, not even asserting that it is what I expect it to be. If I don't, I would just add a @SuppressWarnings(Array("org.wartremover.warts.NonUnitStatements")) and maybe a comment about why and be done with it.

Scala is somewhat unique in that it's a somewhat opinionated language that also tries to integrate with another not-so-opinionated language. This leads to pain points. There are different philosophies to dealing with this, but I tend to not sweat it, and just be aware of and try to isolate the boundaries.

A val definition in Scala expands to a private[this] field with an additional getter. Other than the ValDef you're seeing there should be an additional DefDef method definition with the same name which is the getter on the field.
