About

Jasic is an exercise in simplicity and pedagogy. It is a complete standalone interpreter for a dialect of the original BASIC language that fits inside a single .java file. It handles tokenizing, parsing, interpreting, output, variables, expressions, and flow control, like a full-scale compiler or interpreter, just in miniature. I tried to keep the code simple and readable while still being terse.

If you've ever wanted a gentle introduction to how programming languages work under the hood, Jasic is a good place to start.

Getting Started

You can build Jasic using your big IDE of choice, but the simplest way is just through the command line. Open a command prompt and navigate to the main Jasic directory (where this file is), then do:

javac com/stuffwithstuff/Jasic.java

This compiles the code. To run it, enter:

java com.stuffwithstuff.Jasic

Where it says

java com.stuffwithstuff.Jasic sample/mandel.jas

More Info

The real information about Jasic, including the language syntax and how the interpreter works is all in with the code, so go ahead and read through Jasic.java.
