You can join #debian-java to see daily updates on kotlin. I tend to discuss my design decisions there.
I am currently working on packaging the last 2 dependency packages of kotlin from intellij-community.
Intellij-community is quite a massive source and we need 6 packages from it. Right now 4 are done, I have only pushed the changes of last 3 to the repo here ->
I'll push the changes of the 4th package today as I only finished it yesterday and it needs a little refinement. I'll update the blog with the intellij-community packages as well. Thanks for your interest.
Regards,
Saif
