How turn off/on typer phase in scala repl and sbt console

Question

Is it possible to switch phase without exiting from current session? I've tried entering :power mode, but it still doesn't print types.

Answer 1

In SBT just add the following setting:

set scalacOptions in (Compile, console) := "-Xprint:typer"

in REPL you can use :settings -Xprint:typer
