EarthBox

Simple development framework for earthweb
EarthBox is a fork of Truffle code

EarthBox Documentation

Installation

npm install -g earthbox

OS requirement

  • NodeJS 8.0+
  • Windows, Linux, or Mac OS X

Features

Initialize a Customer Earth-Box Project
earthbox init

Download a dApp, ex: metacoin-box
earthbox unbox metacoin

Contract Compiler
earthbox compile


To compile for all contracts, select --compile-all.

Optionally, you can select:
--compile-all: Force compile all contracts.
--network save results to a specific host network

Configuration

To use EarthBox, your dApp has to have a file EarthBox.js in the source root. This special files, tells EarthBox how to connect to nodes and event server, and passes some special parameters, like the default private key. This is an example of EarthBox.js:

module.exports = {
  networks: {
    development: {
// For earthtools/quickstart docker image
      privateKey: 'da146374a75310b9666e834ee4ad0866d6f4035967bfc76217c5a495fff9f0d0',
      userFeePercentage: 30, // or consume_user_resource_percent
      feeLimit: 100000000, // or fee_limit
      originEnergyLimit: 1e8, // or origin_energy_limit
      callValue: 0, // or call_value
      fullNode: "http://127.0.0.1:8090",
      solidityNode: "http://127.0.0.1:8091",
      eventServer: "http://127.0.0.1:8092",
      network_id: "*"
    },
    mainnet: {
// Don't put your private key here, pass it using an env variable, like:
// PK=da146374a75310b9666e834ee4ad0866d6f4035967bfc76217c5a495fff9f0d0 EARTHBox migrate --network mainnet
      privateKey: process.env.PK,
      userFeePercentage: 30,
      feeLimit: 100000000,
      fullNode: "https://www.earth.engineering",
      solidityNode: "https://www.earth.engineering",
      eventServer: "https://www.earth.engineering",
      network_id: "*"
    }
  }
};

Starting from EarthBox 2.1.9, if you are connecting to the same host for full and solidity nodes, and event server, you can set just fullHost:

module.exports = {
  networks: {
    development: {
// For earthtools/quickstart docker image
      privateKey: 'da146374a75310b9666e834ee4ad0866d6f4035967bfc76217c5a495fff9f0d0',
      userFeePercentage: 30,
      feeLimit: 100000000,
      fullHost: "http://127.0.0.1:9090",
      network_id: "*"
    },
    mainnet: {
// Don't put your private key here, pass it using an env variable, like:
// PK=da146374a75310b9666e834ee4ad0866d6f4035967bfc76217c5a495fff9f0d0 EARTHBox migrate --network mainnet
      privateKey: process.env.PK,
      userFeePercentage: 30,
      feeLimit: 100000000,
      fullHost: "https://www.earth.engineering",
      network_id: "*"
    }
  }
};

Notice that the example above uses Earth Quickstart >= 1.1.16, which exposes a mononode on port 9090.

Contract Migration

earthbox migrate

This command will invoke all migration scripts within the migrations directory. If your previous migration was successful, earthbox migrate will invoke a newly created migration. If there is no new migration script, this command will have no operational effect. Instead, you can use the option --reset to restart the migration script.

earthbox migrate --reset

Parameters by contract (introduced in v2.2.2)

It is very important to set the deploying parameters for any contract. In EarthBox 2.2.2+ you can do it modifying the file

migrations/2_deploy_contracts.js

and specifying the parameters you need like in the following example:

var ConvertLib = artifacts.require("./ConvertLib.sol");
var MetaCoin = artifacts.require("./MetaCoin.sol");

module.exports = function(deployer) {
  deployer.deploy(ConvertLib);
  deployer.link(ConvertLib, MetaCoin);
  deployer.deploy(MetaCoin, 10000, {
    fee_limit: 1.1e8,
    userFeePercentage: 31,
    originEnergyLimit: 1.1e8
  });
};

Start Console

This will use the default network to start a console. It will automatically connect to a TVM client. You can use --network to change this.

earthbox console

The console supports the earthbox command. For example, you can invoke migrate --reset in the console. The result is the same as invoking earthbox migrate --reset in the command.

Extra Features in EarthBox console:

  1. All the compiled contracts can be used, just like in development & test, front-end code, or during script migration.

  2. After each command, your contract will be re-loaded. After invoking the migrate --reset command, you can immediately use the new address and binary.

  3. Every returned command's promise will automatically be logged. There is no need to use then(), which simplifies the command.

Testing

To carry out the test, run the following command:

earthbox test

You can also run the test for a specific file:

earthbox test ./path/to/test/file.js

Testing in EarthBox is a bit different than in Truffle. Let's say we want to test the contract Metacoin (from the Metacoin Box that you can download with earthbox unbox metacoin):

contract MetaCoin {
	mapping (address => uint) balances;

	event Transfer(address _from, address _to, uint256 _value);
	event Log(string s);

	constructor() public {
		balances[tx.origin] = 10000;
	}

	function sendCoin(address receiver, uint amount) public returns(bool sufficient) {
		if (balances[msg.sender] < amount) return false;
		balances[msg.sender] -= amount;
		balances[receiver] += amount;
		emit Transfer(msg.sender, receiver, amount);
		return true;
	}

	function getBalanceInEth(address addr) public view returns(uint){
		return ConvertLib.convert(getBalance(addr),2);
	}

	function getBalance(address addr) public view returns(uint) {
		return balances[addr];
	}
}

Now, take a look at the first test in test/metacoin.js:

var MetaCoin = artifacts.require("./MetaCoin.sol");
contract('MetaCoin', function(accounts) {
  it("should put 10000 MetaCoin in the first account", function() {

    return MetaCoin.deployed().then(function(instance) {
      return instance.call('getBalance',[accounts[0]]);
    }).then(function(balance) {
      assert.equal(balance.toNumber(), 10000, "10000 wasn't in the first account");
    });
  });
  // ...

Starting from version 2.0.5, in EarthBox artifacts () the following commands are equivalent:

instance.call('getBalance', accounts[0]);
instance.getBalance(accounts[0]);
instance.getBalance.call(accounts[0]);

and you can pass the address and amount for the method in both the following ways:

instance.sendCoin(address, amount, {from: account[1]});

and

instance.sendCoin([address, amount], {from: account[1]});

How to contribute
