# wwwBASIC

wwwBASIC is an implementation of BASIC (Beginner's All-purpose Symbolic

Instruction Code) designed to be easy to run on the Web.

## How to use wwwBASIC

You can include wwwBASIC directly in Web pages:

```html

  

    

    

      PRINT "Hello World!"

      FOR i = 1 to 10

        PRINT "Counting "; i

      NEXT i

    

  

```

You can also import wwwBASIC as a Node.js module.

Either install  it via [npm](https://www.npmjs.com/): `npm install -S wwwbasic`

or clone the repository: `git clone https://github.com/google/wwwbasic.git`

Then run your code:

```js

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

`);

```

## Features

It supports a range of features including:

   * Graphics: 24-bit color, PSET, LINE, CIRCLE.

   * Input: INKEY$, GETMOUSE.

   * Source is parsed and compiled to JavaScript at load time.

## Test Suite

wwwBASIC has a "work in progress" test suite.

It can be run with: `./tests/run-tests.sh`.

## But Why?

The immediate trigger for wwwBASIC's existence was

Ed Thelen's Nike Hercules

[simulator](http://ed-thelen.org/NikeSimulation.html#SimBrowser).

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](http://ed-thelen.org/nike-fromBradNelsonSept26.html) to run.

From there, bringing up

[DONKEY.BAS](https://google.github.io/wwwbasic/examples/donkey.html)

seemed a nice logical milestone.

Bringing up GORILLA.BAS and NIBBLES.BAS are a current focus.
