Scheme Interpreter

This project implements a Scheme Interpreter for RSR5 in C. The project builds off a linkedlist represented as a cons type (Scheme), and uses Value structs(see value.h) to store information about each token seen in the input. These tokenized inputs(generated using the tokenizer in tokenizer.c) are parsed using a modified/simplified recursive descent parser, and are finally interpreted(see interpreter.c for details). The evaluation is done using an environment (and frame) model.

Limitations

The program does not handle all scheme commands. For details, look at the bindings and special forms in interpreter.c.

Usage

To Run:

1. Go to Directory
2. make interpreter < testFile
3. make memtest < testFile for memory tests using Valgrind.
4. make clean to remove all compiled files.

testFile could be selected from the list of test cases in directory: test-cases

Credits

Big thanks to Kelsey Krantz and Lindsey Chavez for providing solid support. Prof. Jed Yang was an invaluable resource in figuring out problems with the interpreter. All test cases were tested in racket which was an great resource.
