This is a helper to compile and deploy smart contracts through geth.
Install solc compiler.
Move solc_helper to somewhere in your path.
To compile your code run
solc_helper contract.sol
This will generate a javascript file and print out a statement like the following.
loadScript('/path/contract.js')Paste this statement into the geth console. Your code will be loaded and your contract will be deployed automatically.
There are also a few helper functions to easily deploy the contracts.
create(abiDefinition);
deploy(account, value, gas, contract, code, input=optional);You can use them to deploy the contract.
var contract = create(compiled.SimpleStorage.info.abiDefinition);
var instance = deploy(eth.coinbase, 0, 10000, contract, compiled.SimpleStorage.code,10);
var instance = deploy(eth.coinbase, 10, 10000, contract, compiled.SimpleStorage.code); // if there are no constructor parameters.To call a function in the contract you can use the call function
call(accountIndex, gas, contractInstance.function, input);
//For example to call using ether from eth.accounts[1]
call(1, 100000, multiplier.multiply, 1, 2);To watch an event you can use the watcher function.
contractInstance.eventName(watcher);To send some ether from your account to another. You can use send function
send(accountIndex, toAccount, valueInEther, gas);
//For example to send some ether from eth.accounts[2]
send(2, '0xb8290f9757b5c9daa11a8016d663829af812fc0e', 10, 30000);Use bal() function to check balance of all accounts.
The script will also printout the gas estimates when you try to compile.
