I have been tracking those changes in 2.11 as well. We would need a simple wrapper around ILoop, set the Yreplclassbased flag, an HttpServer to export the repl-outdir, bind sc into repl namespace and maybe little more initialization (customizing repl init code in 2.11 is not as trivial as the <=2.10 versions, but still doable.) Still, even with all this, it should be much simpler than pulling in and refactoring everything like today. I already have a prototype for this in my working tree, still needs integration testing. > BTW did the non-REPL parts run fine on 2.11? > Currently fighting to get all the dependencies in 2.11. Quick pointer where I can get sources for akka-*-X.Y-shared-protobuf? Also, what's the smallest set of dependencies to build the smallest testable subset of the project?
