wwwBASIC is an implementation of BASIC (Beginner's All-purpose Symbolic Instruction Code) designed to be easy to run on the Web.
You can include wwwBASIC directly in Web pages:
<html> <head> <script src="https://google.github.io/wwwbasic/wwwbasic.js"></script> <script type="text/basic"> PRINT "Hello World!" FOR i = 1 to 10 PRINT "Counting "; i NEXT i </script> </head> </html>
You can also import wwwBASIC as a Node.js module.
Either install it via npm:
npm install -S wwwbasic
or clone the repository:
git clone https://github.com/google/wwwbasic.git
Then run your code:
var basic = require('wwwbasic'); // from NPM // var basic = require('./wwwbasic.js'); // from within the cloned repository directory basic.Basic( ` PRINT "Hello World!" FOR i = 1 to 10 PRINT "Counting "; i NEXT i `);
It supports a range of features including:
wwwBASIC has a "Work-in-progress" test suite.
It can be run with:
The immediate trigger for wwwBASIC's existence was Ed Thelen's Nike Hercules simulator. It had been written in BASIC some time back, then ported to some unknown version of FreeBasic. However, while he had screenshots and source code, it also included a Windows .EXE to a download, and the statement, "guaranteed to be free of viruses" :-/
As it was meant to capture how something historical worked, it seemed unfortunate that something of this sort couldn't just be accessible directly on the web. Various whole system emulators that run on the web are available, but booting a whole system for a small program seemed like overkill.
Hence the first goal was to get this to run.
From there, bringing up DONKEY.BAS seemed a nice logical milestone. Bringing up GORILLA.BAS and NIBBLES.BAS are a current focus.
