Rascal implementation of the MiniJava subset of Java

Currently provides:

• syntax (concrete), module lang::minijava::Syntax
• dynamic semantics (purely functional definitional interpreter), module lang::minijava::Interpreter, tested by lang::minijava::tests::Interpreter
• a funcon translation, module lang::minijava::FunconTranslation, tested by lang::minijava::tests::FunconTranslation

The tests use the example programs in examples/ which are also valid Java programs. The semantic descriptions provided by the definitional interpreter and by the funcon translation for the (unextended) minijava language should match the semantics of Java.
