I have a file with several lines of scala code — imports, list value assignments, etc. that I often use to initialize some things when using the REPL.
Currently I just open up the file in a text editor and copy-and-paste it into the REPL, but is there a way to do it by calling the external file in a more direct manner so I don’t have to copy-and-paste every time?
In some interactive database tools like SQL Plus, it is done by typing @filename at the prompt. Is there something similar in the Scala REPL? Preceding the filename with @ doesn’t work, eval doesn’t work either.

and you see, that
solves your problem.
In some circumstances, pasting the code might be preferable though, but then
might be your friend then. It helps inserting a whole block without feedback, line by line, until you hit Ctrl + D. In some cases this is significant for the code interpretation.
