Bug report for the gRPC plugin

we will cover everything in the end

That’s great to hear. But some of the things I did in the community plugin was code heavy, I worry that they might be philosophically incompatible with the rest of Gatling.

Speaking of philosophy, what do you think about the use of lens+expression with ScalaPB generated messages?

Compare the following Scala snippet:

for {
  firstName <- session("firstName").validate[String]
  lastName <- session("lastName").validate[String]
} yield Greeting(firstName, lastName)

and the corresponding Kotlin code:

greeting {
    firstName = session.get("firstName") ?: "null"
    lastName = session.get("lastName") ?: "null"
}

In the Scala version firstName appears 3 times (will be four if you use named arguments) - twice are intermediate variables; and the type String has to be provided explicitly. It doesn’t sit well with me that the Scala code is more verbose than the Kotlin version.

But I also know that the lens magic I did was confusing for many. I’d love to hear your thoughts on that.
