======

C-like Structs for JavaScript.

A browser porting of the Node.js [Struct library](https://github.com/xdenser/node-struct).

Install

============

``` 

npm install js-struct-agb

```

    

Example

=======

Define some structure: 

	import Struct from 'js-struct-agb';

 

	var Person = Struct()

		.chars('firstName',10)

		.chars('lastName',10)

		.array('items',3,'chars',10)

		.word16Sle('balance'),

	People = Struct()

		.word8('presentCount')

		.array('list',2,Person);

		

Now allocate buffer for it

	

	People.allocate();

	var buf = People.buffer();

	

Clear buffer to see how it will change later:

	

	var buf = People.buffer();

	for (var i = 0; i < buf.length ; i++) {

  		buf[i] = 0;

	}

	console.log(buf);

	

Output:

	

	

	

Now you can access memory as defined binary structure with `fields` property in a handy manner.		

	var proxy = People.fields;

	proxy.presentCount = 2;

	console.log(buf);

	

Output: 

	

	

	

And so on

	proxy.list[0].firstName = 'John';

	console.log(buf);

	

Output:
