Plot is a simple implementation of Scheme designed to teach the basics of implementing an interpretive programming language.
Making an interpreted language consists of a few steps that include building the following pieces.
- Lexical Analyzer
- Parser
- Environment Module
- Evaluator
Plot's interpreter will be written in Java 1.8, and will utilize new features in Java like lambdas.
This is a 5 part workshop. In the first workshop we'll explain how to run the project, and go over a simple BNF notation for our language's grammar. And in each of the following workshops we'll implement each module. The full code will be available before the workshop.
This git repository will have the full source available upon the first workshop. Important completed events will be tagged with their module names, so you can work at your own speed.
During the workshop, we'll program everything until the next subsequent version and explain it as we go. Important modules and what commit their found in are in the table below:
| Module | Commit Hash |
|---|---|
| Grammar | 9f8c99c |
| Lexical Analyzer | e887b04 |
| Parser | 77f2afc |
| Environment Module | 234b741 |
| Evaluator | 7bc1bdb |
Additional functionality to the language is encouraged, however the author leaves it up to those experimenting with languages to implement additional functionality.
If you'd like to contribute, create an issue, fork the repository and issue a pull request. We'll do our best to review it.
