rich repl console

Just to confirm... this would be something to go in the nsc codebase, hence the decision to start with scala-internals

This could give us some nice benefits over working with the raw O/S console such as sensible copy/paste behaviour with ctrl-c & ctrl-v, colour highlighting, menu options to explore and manipulate the classpath, available package space, AST, etc.
It also works around the problem with MS windows where j-line hangs if launched in a spawned process with redirected I/O

If anyone's already started anything like this, or has idea/suggestions/warnings/etc, then I'm happy for the feedback.

I think it'd would be a better plan to make the minimal changes
necessary to the nsc codebase to allow this kind of thing to be done
externally. If nothing else, all of the IDEs would benefit from
something this sort.

I'm not sure why it would go into the nsc codebase. DRMacIver started
a project like this some time ago, though I can't find it now.

Emacs is pretty good at handling the Scala REPL, either from within
the Scala mode, or just from an M-x shell with no configuration. Yes,
on Windows too. Yes, I realise most Windows users won't use emacs.

Got to say, I'm especially liking Mile's suggestion; just push in the relevant hooks to nsc.If we can pull out the existing repl/console stuff as well like MainGenericRunner and the jline dependency then even better!
This would help with IDEs, it would also be useful for allowing a REPL connection to a remote JVM for diagnostic purposes.
The emacs thing is interesting, but seems to be heading in a different direction from my current plans. One of my goals is being able to launch the REPL console directly via the scala maven plugin or SBT with the project classpath already set up.Of course, the emacs plugin would be more than happy to use any new hooks...
