support for scala 2.12

[devmacmari]

I couldn't find any scala 2.12 artifact on maven. Is scala 2.12 going to be supported? Thanks : )

Due to the changes in the way that traits are handled, Scala 2.12 has a regression in Specialization which prevented us from releasing the 2.12 build. Scala Specialization ensures high performance when delivering events of primitive types (Int, Double, and Long). So, we're waiting for this issue to be resolved:

scala/bug#10277

While it's possible to disable specialization in the Reactors build with a compiler flag, we decided to postpone the 2.12 release until the above bug is resolved in Scala, since we don't want to release a version with inferior performance. If you really need the 2.12 version, one suggestion is to check out the source, change the version to 2.12 in the project/Build.scala file, add the -no-specialization flag to the list of compiler flags, and build the artifact manually.

I was somewhat worried on using this project, because I thought lack of support for scala 2.12 meant this project was abandoned (or in 'maintenance-only' mode).
But your reply clears things up for me. thanks for the reply : )

ps: should I close this? or should I leave it open for future reference?

You're welcome! No need to close this - it's good to have the plan documented.

I just stumbled upon the Reactors.IO framework today while reading the "Learning Concurrent Programming in Scala" book. However, looks like Scala 2.12 is still not supported which is a deal-breaker. Looks like I will need to go back to Actors then.

Any news on this one? Lack of support for scala 2.12/2.13 is a deal break for me as well. The specialization issue seems to be fixed now. Is no one maintaining this project now?

I'm sorry, I unfortunately do not have the cycles to do the maintenance right now.
I would suggest forking the project, and publishing the 2.12/2.13 version.

That makes sense, thanks! I'm not sure if I'm the person to do it--no cycles either--but I'll mull it over!

Will there be a 2.12/2.13 release at some point?
I'm not hoping for 3... 😅
