# python-struct

[![npm Version](https://badge.fury.io/js/python-struct.png)](https://npmjs.org/package/python-struct)

Packs/Unpacks/Measures structs according to Python's `struct` format

## Installation:

```
npm install --save python-struct
```
  
## Usage example:

```javascript

const struct = require('python-struct');

struct.sizeOf('>iixxQ10sb'); // --> 29

struct.pack('>iixxQ10sb', [1234, 5678, require('long').fromString('12345678901234567890'), 'abcdefg', true]); // --> <Buffer 00 00 04 d2 00 00 16 2e 00 00 ab 54 a9 8c eb 1f 0a d2 61 62 63 64 65 66 67 00 00 00 01>

struct.unpack('>iixxQ10sb', Buffer.from('000004d20000162e0000ab54a98ceb1f0ad26162636465666700000001', 'hex')); // --> [ 1234, 5678, 12345678901234567890, 'abcdefg', 1 ]

```

## Usage in the browser

The `"browser"` entry in `package.json` will automatically redirect to the browser adapter for the package.  
*But* you'll have to `npm i buffer` in your project.

## Notes

When using "native" size & alignment, we do not really have a way to find the native size of alignment of types.  
But it's almost always safe to assume that `node_adapter.js` is compiled for the standard architectures, so `native` behaves like `standard`.

If anyone stumbles across a different case, I'll be happy to review it on that specific instance, and figure out what to do.
