LucreConfluent

Build Status Maven Central

statement

LucreConfluent is (C)opyright 2009–2015 Hanns Holger Rutz. It is released under the GNU Lesser General Public License v2.1+.

LucreConfluent provides a transactional, durable, and confluently persistent memory framework for the Scala programming language. It implements a transform which was described by Fiat/Kaplan and which is extended with the support for the representation of multiplicities and quasi-retroactive fluent references as well as event propagation (provided separately through the ConfluentReactive library). It uses LucreSTM for the transactional layer, and builds on top of data structures provided by the LucreData project. The overall target is integration with a system for computer music composition.

building

Builds with sbt 0.13 against Scala 2.11, 2.10, using standard sbt targets. The dependencies, LucreData and FingerTree should be found automatically by sbt.

linking

The following dependency is necessary:

resolvers += "Oracle Repository" at "http://download.oracle.com/maven"

"de.sciss" %% "lucreconfluent" % v

The current version v is "2.11.3".

previous versions / tags

Note: see tag v0.14 for the example using actual audio file regions and sonogram view. The current version is a rework based on a new modularisation.
