It should be trivial to create a Scheme interpreter in Java. Actually, you don't even need a scheme interpreter: you just need a set of classes to represent common Scheme types, and a virtual member function on the base class to print out an s-expression. That way we can use its output directly into a Scheme script that executes the Java code on the t-expr input, slurps its s-expr output, and compares it to the reference s-expr. Not having actually studied Java, though, means that I can't actually do it, LOL. But ANTLR has C++, right? That I could write. ------------------------------------------------------------------------------ Master Java SE, Java EE, Eclipse, Spring, Hibernate, JavaScript, jQuery and much more.
