Has anyone developed a nice way of wrapping the generated java builders to make things a bit nicer in kotlin? At the moment we are doing

val message = with(MyMessage.newBuilder()) {
    someField = 1
    build()
}

I was thinking it would be nicer to do something like....

val message = build(MyMessage) {
   someField = 1
}

... but my Kotlin isn't good enough to be able to write that build function yet 😄

Take a look at https://github.com/marcoferrer/kroto-plus - you can generate dsl style builders using gradle

[Mark Allanson]

Any idea if this works with quarkus-grpc? I'd guess not

[Mark Allanson]

Thanks for the pointer though!

[Dariusz Kuc]

I'd assume you should be able to generate DSL style builders and use it with anything as underlying libs generally still depend on protoc java compiler (e.g. we use kroto+ DSL with grpc-kotlin)

[Mark Allanson]

Yeah I was investigating that right now - if I can wire in the kroto+ message builders

There are words of open-sourcing an "official" Google supported Kotlin proto generators (see on the gRPC-Kotlin issue tracker), but nothing there yet afaik
