Assignment

Write an interpreter in Java for the subset of Scheme used in assignment 4. (In other words, redo the first interpreter from that assignment in Java.)

This assignment has many classes that you will use, but you should only change the file Eval_Exp.java. Javadoc documentation for all of the classes can be found here.

There are five packages in this project:

scheme.parser - Files in there were autogenerated by some tool. You don't need to look at them.
scheme.util - A couple of classes to implement lists.
scheme.absyn - Abstract syntax. Useful to look at the javadoc but should not be touched.
scheme - The top level. It has one file REPL, which simulates a repl.
scheme.interp - This is the meat of the interpreter. Some of the methods in Eval_Exp.java are not done. You need to finish them.

Submission

Turn in the file Eval_Exp.java on the electronic submission page.
