java-leaderboard

Leaderboards backed by Redis in Java, http://redis.io.

Builds off ideas proposed in http://blog.agoragames.com/2011/01/01/creating-high-score-tables-leaderboards-using-redis/.

Installation

You should be able to use the following as a dependency in your Maven pom.xml:

<dependency>
  <groupId>com.agoragames</groupId>
  <artifactId>leaderboard</artifactId>
  <version>2.0.1</version>
</dependency>

Make sure your redis server is running! Redis configuration is outside the scope of this README, but check out the Redis documentation, http://redis.io/documentation.

Compatibility

The JAR has been built under OS X using the following Java Runtime:

java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07-334-10M3326)
Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-334, mixed mode)

Usage

For now, look at the Scala leaderboard documentation, https://github.com/agoragames/scala-leaderboard, or the tests for usage.

Future Ideas

Contributing to java-leaderboard

Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
Fork the project
Start a feature/bugfix branch
Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the pom.xml, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
