title: Small/toy language compiler/interpreter implemented in Java
body: <p>I'm looking for a small/toy programming language that is implemented in Java. The implementation should preferably not be much more than around a 1000 lines or so. It might e.g. be a simple imperative language, an expression parser/interpreter or something similar. The intention is to use it as an example for a paper I'm writing, and while I could mock up something myself, it would be better to be able to refer to something that already exists. Thanks!</p>
