Quark Framework

The Quark Framework (Open Quark) consists of a non-strict functional language and runtime for the Java platform. The framework allows the compilation and evaluation of functional logic on the Java Virtual Machine (JVM), directly or under the control of a regular Java application. The native language (syntax) for the Quark Framework is called CAL. A full range of Java APIs provides the means to invoke the CAL compiler, manipulate workspaces of modules, add metadata and evaluate functional logic. Functional logic is usually dynamically compiled to Java bytecodes and executed directly on the JVM (with some small kernel logic controlling the normal evaluation order). However, an interpreter (G-machine) is also available.
