Congrats to the scala community and the team that worked on this.

If there's a feature you'd like to see in a future release, you can suggest it here: https://groups.google.com/forum/?hl=en#!forum/scala-ide-dev

Great, thanks for the info!

Finally IntelliJ Scala got a serious competitor.

The features in the video look great, hopefully they also work like that in practice!

Looks great and tooling might be a reason for me to try to pick up Scala again.

But part of the post (supporting 3 different versions Scala versions, with different IDE branches for each and the combinatorial result) resonated with me and reminded me of the recent (?) article about the inability of mixing libraries compiled with different versions of Scala.

If someone from the team is here: How hard is this problem affecting the IDE project?

IntelliJ IDEA FTW!

I think it's great they're making the kinds of improvements the community has been asking for. Then again, I too read that list and thought "isn't that what I take for granted in IntelliJ?"

The problem affects us not at all, as we build from source.

The compatibility problem is a different one: Unlike almost everybody else, Scala IDE uses the standard Scala compiler in presentation mode. That compiler has undergone changes from 2.8 to 2.9 to trunk. The IDE needs to work with all three versions.

What's "presentation mode"?

Using various parts of the original compiler as a asynchronous, interruptible, focused service for use in IDE.

This fixes the problems usually occurring when people have to re-implement type checkers/compilers, see for example the problems when Eclipse's Java stuff disagrees with javac or ecj creates different bytecode and breaks assumptions of other tools.

IntelliJ is very good for Scala, more responsive too. One of the intellij plugin updates did get very confused and was falsely highlighting errors in my project, haven't checked for a more recent update, but it was fairly recent. Glad to see the eclipse plugin getting some tlc, since most java devs love using eclipse even in cases where it's not the best choice.
