Re: Xtend 2.3 beta
Do I need to use Juno to build it? I've had trouble using Indigo to build it in the past, because of some dependency problems. I think I need to be able to build it to add in the closure extensions I'm using -- unless you guys have folded those in :).

Re: Xtend 2.3 beta
Great going, developers!
Not to steal the limelight from your efforts, but I would like to suggest that (if possible), giving higher priority to language changes might be better than tooling changes at this stage.
In any case, good show!

Re: Xtend 2.3 beta
Thanks, for the kind words.
Which language improvements would you like to see?

From the top of my mind:
- Support for decimal literals
- Type inference for fields
- Traditional for loops
- Something similar to case class from Scala
- Tuples

That's included in the beta.
Yep, that's something we want to do very soon.
- Type inference for fields
What's the motivation?
- Traditional for loops
I always use the range operator when i need an index.
for (x : 0..list.size) {
val ele = list.get(x)
}
- Something similar to case class from Scala
We are going to experiment with a more general support for annotation processing, with which such things can easily be done (and even customized to your needs).
- Tuples
You mean tuple types, as a short cut for
Pair<String, Boolean> and Triple<Foo,Bar,Baz> ?
Not sure if that's worth it. Any examples where the currently available support isn't sufficient?
Thanks,
Sven

Well, I might want to traverse the array with a different stride than 1, or jump over values sometimes, or have two index variables incrementing at different paces. The traditional for loop is very flexible. It is true that the same can be achieved with a while() loop, but the traditional for loop has an easily recognised syntax.
Sounds interesting.
I wasn't aware of Triple, so that's good. Nevertheless, Tuples with arbitrary length will be better. (I understand true arbitrary length Tuples will be difficult, but some sane limit like 22 in Scala is sufficient for practical purposes).
I guess the main thrust of my request is to have a generic syntax for Tuples, so that when I change a binary Tuple (Pair) to say a Ternary Tuple (Triple), I don't have to change the types everywhere. (Type inference does help in some cases, but not always.)
I am coming from a Scala background, but for performance reasons I am stuck with Java for my projects. If Xtend can give me features like Scala (wherever possible) with the raw performance of Java, I would be a happy convert.
cheers,

Re: Xtend 2.3 beta
"'it' and 'this' are not allowed as member names" is this new in the beta?
