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

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

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

)

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
