BufferPut

===

Pack multibyte binary values into buffers with specific endiannesses.  Based

on the original Put by https://github.com/substack/node-put ...this version

is intended to be a little more conventional in structure and faster

to instantiate and easier for a VM to optimize.  Instantiation of this version

is more that 500x faster than the original as measured on nodejs 0.10.12.

Installation

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

To install with [npm](http://github.com/isaacs/npm):

 

    npm install bufferput

To run the tests with [expresso](http://github.com/visionmedia/expresso):

    expresso

Examples

========

buf.js

------

Build a buffer

    #!/usr/bin/env node

    var BufferPut = require('bufferput');

    var buf = (new BufferPut())

        .word16be(1337)

        .word8(1)

        .pad(5)

        .put(new Buffer('pow', 'ascii'))

        .word32le(9000)

        .buffer()

    ;

    console.log(buf);

Output:

    

stream.js

---------

Send a buffer to a writeable stream

    #!/usr/bin/env node

    var BufferPut = require('bufferput');

    (new BufferPut())

        .word16be(24930)

        .word32le(1717920867)

        .word8(103)

        .write(process.stdout)

    ;

Output:
