What is the best way to print history of code executed in ammonite repl in previous sessions? I am aware of repl.history but it contains code from current session and I know that ammonite keeps history of previous sessions because snippets from them are available using "up arrow" key.
On Linux or Mac history is stored in your home directory in file ~/.ammonite/history, so you could maybe just load it from file:
import scala.util.Using
import scala.io.Source
val history = Using(Source.fromFile("/path/to/home/.ammonite/history"))(_.getLines)
