A modern programming language that makes developers happier.

kotlinlang

as an example how would I build this?
```message DateRange {
  // The beginning of the date range
  google.type.Date from = 1 [(validate.rules).message.required = true];

  // The end of the date range
  google.type.Date until = 2 [(validate.rules).message.required = true];
}```


The generated class isn't particularly helpful:

by default, you would use `grpc-java` way of using builders
```DateRange.newBuilder()
  // set your fields using their builders
  .build()```

if you use the `grpc-kotlin` then you should be able to use the generated DSL which should be something among the lines
```dateRange {
  from = ...
  unti = ...
}```

Thanks, the second one seems to be the right path, but now I have to figure out how to create a `com.google.type.Date` ; doesn't seem to use the DSL syntax and none of the constructors appear to be the right approach, but maybe I'm missing one

Wait I think I have it:
```val dateRange = dateRange {
            from = newBuilder().setDay(7).setMonth(7).setYear(2022).build()
            until = newBuilder().setDay(12).setMonth(7).setYear(2022).build()
        }```
I guess what I don't get it when I'm supposed to be using the DSL syntax like `dateRange { ... } ` instead of the other builder syntax

I'd imagine you should also have
```date {
  day = 7
  month = 7
  year = 2022
}```


*unless google protos are treated in some custom special way

yeah that doesn't seem to work, unfortunately

I suspect this comes down to your build system and how Google's protos are built by it

You'll need to run the Kotlin proto compiler on them to get those DSL "factories"
