To work with the repository you will need scala-cli.
After running
scala-cli setup-ide .
you can import the project to the IDE of your choice.
There is a script file that will help prograssing with excercises.
To reset all excercises run
./course.sc reset
To move to the next step in one of the excercises (e.g. 7) run
./course.sc 7 next
To see all options run
./course.sc --help
On windows you may have to use longer form of invocation, so to go to the next stop in excercise 7, run:
scala-cli course.sc -- 7 next
