Packages
Binaries
========
Ethereum Go is split up in several sub packages Please refer to each
individual package for more information.
1. [eth](https://github.com/ethereum/go-ethereum)
2. [ethchain](https://github.com/ethereum/go-ethereum/tree/master/ethchain)
3. [ethwire](https://github.com/ethereum/go-ethereum/tree/master/ethwire)
4. [ethdb](https://github.com/ethereum/go-ethereum/tree/master/ethdb)
5. [ethutil](https://github.com/ethereum/go-ethereum/tree/master/ethutil)
6. [ethpipe](https://github.com/ethereum/go-ethereum/tree/master/ethpipe)
7. [ethvm](https://github.com/ethereum/go-ethereum/tree/master/ethvm)
8. [ethtrie](https://github.com/ethereum/go-ethereum/tree/master/ethtrie)
9. [ethreact](https://github.com/ethereum/go-ethereum/tree/master/ethreact)
10. [ethlog](https://github.com/ethereum/go-ethereum/tree/master/ethlog)
Go Ethereum comes with several binaries found in
[cmd](https://github.com/ethereum/go-ethereum/tree/master/cmd):
The [eth](https://github.com/ethereum/go-ethereum) is the top-level package
of the Ethereum protocol. It functions as the Ethereum bootstrapping and
peer communication layer. The [ethchain](https://github.com/ethereum/go-ethereum/tree/master/ethchain)
contains the Ethereum blockchain, block manager, transaction and
transaction handlers. The [ethwire](https://github.com/ethereum/go-ethereum/tree/master/ethwire) contains
the Ethereum [wire protocol](http://wiki.ethereum.org/index.php/Wire_Protocol) which can be used
to hook in to the Ethereum network. [ethutil](https://github.com/ethereum/go-ethereum/tree/master/ethutil) contains
utility functions which are not Ethereum specific. The utility package
contains the [patricia trie](http://wiki.ethereum.org/index.php/Patricia_Tree),
[RLP Encoding](http://wiki.ethereum.org/index.php/RLP) and hex encoding
helpers. The [ethdb](https://github.com/ethereum/go-ethereum/tree/master/ethdb) package
contains the LevelDB interface and memory DB interface.
* `mist` Official Ethereum Browser
* `ethereum` Ethereum CLI
* `ethtest` test tool which runs with the [tests](https://github.com/ethereum/testes) suit:
`cat file | ethtest`.
* `evm` is a generic Ethereum Virtual Machine: `evm -code 60ff60ff -gas
10000 -price 0 -dump`. See `-h` for a detailed description.
* `rlpdump` converts a rlp stream to `interface{}`.
* `peerserver` simple P2P (noi-ethereum) peer server.
* `disasm` disassembles EVM code: `echo "6001" | disasm`

// Package abi implements the Ethereum ABI (Application Binary
// Interface).
//
// The Ethereum ABI is strongly typed, known at compile time
// and static. This ABI will handle basic type casting; unsigned
// to signed and visa versa. It does not handle slice casting such
// as unsigned slice to signed slice. Bit size type casting is also
// handled. ints with a bit size of 32 will be properly cast to int256,
// etc.

This abstracts part of a user's interaction with an account she controls.
It's not an abstraction of core Ethereum accounts data type / logic -
for that see the core processing code of blocks / txs.
Currently this is pretty much a passthrough to the KeyStore2 interface,
and accounts persistence is derived from stored keys' addresses

# Ethereum JavaScript API
This is the Ethereum compatible JavaScript API using `Promise`s
which implements the [Generic JSON RPC](https://github.com/ethereum/wiki/wiki/Generic-JSON-RPC) spec.
For an example see `index.html`.
**Please note this repo is in it's early stage.**
If you'd like to run a WebSocket ethereum node check out
[go-ethereum](https://github.com/ethereum/go-ethereum).
To install ethereum and spawn a node:
```
go get github.com/ethereum/go-ethereum/ethereum
ethereum -ws -loglevel=4
```

# Ethereum JavaScript API
This is the Ethereum compatible [JavaScript API](https://github.com/ethereum/wiki/wiki/JavaScript-API)
which implements the [Generic JSON RPC](https://github.com/ethereum/wiki/wiki/Generic-JSON-RPC) spec. It's available on npm as a node module and also for bower and component as an embeddable js
[![NPM version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url] [![dependency status][dep-image]][dep-url] [![dev dependency status][dep-dev-image]][dep-dev-url]
<!-- [![browser support](https://ci.testling.com/ethereum/ethereum.js.png)](https://ci.testling.com/ethereum/ethereum.js) -->
## Installation
### Node.js
npm install ethereum.js
### For browser
Bower
bower install ethereum.js
Component
component install ethereum/ethereum.js
* Include `ethereum.min.js` in your html file.
* Include [bignumber.js](https://github.com/MikeMcl/bignumber.js/)
## Usage
Require the library:
var web3 = require('web3');
Set a provider (QtProvider, WebSocketProvider, HttpRpcProvider)
var web3.setProvider(new web3.providers.WebSocketProvider('ws://localhost:40404/eth'));
There you go, now you can use it:
```
var coinbase = web3.eth.coinbase;
var balance = web3.eth.balanceAt(coinbase);
```
For another example see `example/index.html`.
## Contribute!
### Requirements
* Node.js
* npm
* gulp (build)
* mocha (tests)
```bash
sudo apt-get update
sudo apt-get install nodejs
sudo apt-get install npm
sudo apt-get install nodejs-legacy
```
### Building (gulp)
```bash
npm run-script build
```
### Testing (mocha)
```bash
npm test
```
**Please note this repo is in it's early stage.**
If you'd like to run a WebSocket ethereum node check out
[go-ethereum](https://github.com/ethereum/go-ethereum).
To install ethereum and spawn a node:
```
go get github.com/ethereum/go-ethereum/ethereum
ethereum -ws -loglevel=4
```
