Dartmouth BASIC interpreter written in Java.
The interpreter supports a major subset of the 4th (and thus earlier) edition of the language. The language is described for instance here .
The project consists of the interpreter build as a library and a simple executable application using it.
Developed to celebrate BASIC's 50th birthday.
To build the project you need Maven 3 and JDK 8.
Sample usage of the library is best shown in the app itself. To use the interpreter app just type:
java -jar jbasic.jar your_script.bas
You can also specify the logging level via (e.g. -log=TRACE) to see exactly what's going on inside.
Ideas, things to be done or fixed are pointed out in the source files. They include:
- support for matrices (
MAT), - support for arrays (
DIM), - parsing scientific notation (eg.
1.2e10), - support for configuring runtime environments,
- refactoring of expression parser.
