Scalar DB example

A very small simple CLI application to use Scalar DB. This application supports some commands to create a player and make a player attack another player and etc.

Build

$ ./gradlew installDist

Database schema setup

This tool uses schema-loader. Build schema-loader in advance.

$ SCHEMA_LOADER_JAR_PATH=$HOME/src/scalardb/schema-loader/build/libs/scalardb-schema-loader-4.0.0-SNAPSHOT.jar ./setup.sh 

Execute command

$ cd build/install/scalardb-example-player-battle/
$ bin/scalardb-example-player-battle -h

Optional[Player[id=alice, hp=100, attack=15]]

Delete a player

$ cd build/install/scalardb-example-player-battle/

Optional.empty

Show a player

$ cd build/install/scalardb-example-player-battle/
$ bin/scalardb-example-player-battle --config ../../../scalardb.properties get --id alice

$ bin/scalardb-example-player-battle --config ../../../scalardb.properties get --id bob
Optional[Player[id=bob, hp=200, attack=10]]

Attack another player

$ cd build/install/scalardb-example-player-battle/
