Logo Interpreter in Java

Torgo is a Logo interpreter written in Java. It uses ANTLR as a language parser and for lexical analysis. The parsed scripts are then walked to interpret the commands.

Torgo is built using Java8.

Some goals for Torgo are:

• to allow people to learn to program
• to show how machines execute programs
• to allow modifications and add to languages to change behaviors

This project was inspired by Tortue.

Torgo currently supports logo; jvmBasic and lisp are in development.
