This project was written with Scala and SBT (Simple Build Tool).

It uses the new Command Line Application support in SBT to manage and validate user input as documented here.

This feature requires you to be running at least version 0.12 of SBT. You can find instructions for installing that here

The following commmands run from the root directory of the project will start and play the first few frames of a game,

./sbt @bowling.build.properties
addPlayer Caoilte
addPlayer Walter
addPlayer Donny
start
score 10
score 2
score 8

etc

Because it uses SBT for command line support, command history and Parser Combinator tab completion come for free. For example, after entering score 2 above, pressing tab will display 0-8 as valid completions for the next score.

Once the game has finished it will print the final scores and then start a new game requiring new players names to be entered.

If you want to build the application yourself you will need to run the following commands

rm -rf project/boot/
./sbt
test
publish-local

The first rm removes the cached binaries. There is probably a good workaround for it, but I did not have sufficient time to investigate yet.
