EarthCli

Development framework for EARTH. Everything needed to write, compile and deploy smart contracts and tokens. Also includes network management, a full testing framework, configurable build & asset pipeline and more.

Installation

npm install earthcli -g

OS requirement

NodeJS 8.0+

Windows, Linux, or Mac OS X

Features

Initialize a Customer EarthCli Project earthcli init

Download a dApp, ex: coin-box earthcli unbox coin-box

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

module.exports = { networks: { development: { // For earthengineering/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 EarthCli 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.

IMPORTANT

Make sure to copy soljson_v0.5.4.js to ~/.earthcli/solc

cd ~ /.earthcli/solc wget https://raw.githubusercontent.com/EarthEngineering/earth-solc-bin/master/bin/soljson_v0.5.4.js

Contract Migration

earthcli migrate

This command will invoke all migration scripts within the migrations directory. If your previous migration was successful, earthcli 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.

earthcli migrate --reset

Parameters by contract

It is very important to set the deploying parameters for any contract.

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.

earthcli console

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

Extra Features in EarthCli console:

All the compiled contracts can be used, just like in development & test, front-end code, or during script migration. After each command, your contract will be re-loaded. After invoking the migrate --reset command, you can immediately use the new address and binary. 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:

earthcli test

You can also run the test for a specific file：

earthcli test ./path/to/test/file.js

Testing in EarthCli 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 earthcli unbox coin-box ):

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/coin-box.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"); }); }); // ...

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

Fork this repo. Clone your forked repo recursively, to include submodules, for example:

git clone --recurse-submodules -j8 git@github.com:earthengineering/earthcli.git

If you use nvm for Node, please install Node 8, and install lerna globally:

nvm install v8.16.0 nvm use v8.16.0 npm i -g lerna

lerna bootstrap

During the development, for better debugging, you can run the unbuilt version of EarthCli, for example

./earthcli.dev migrate --reset
