Contract compilation is described in detail here; an example may look like:
./geth --datadir ~/eth/ --loglevel 6 --logtostderr=true --rpc --rpcport 8100 --rpccorsdomain '*' --mine console 2>> ~/eth/eth.log
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_compileSolidity","params":["contract test { function multiply(uint a) returns(uint d) { return a * 7; } }"],"id":1}' http://127.0.0.1:8100
(make sure you are connecting to the right ports).
Contract deployment is shown here:
source = "contract test { function multiply(uint a) returns(uint d) { return a * 7; } }"
// compile with solc
contract = eth.compile.solidity(source).test
// create contract object
var MyContract = eth.contract(contract.info.abiDefinition)
// extracts info from contract, save the json serialisation in the given file,
contenthash = admin.saveInfo(contract.info, "~/dapps/shared/contracts/test/info.json")
// send off the contract to the blockchain
MyContract.new({from: primaryAccount, data: contract.code}, function(error, contract){
if(!error && contract.address) {
// calculates the content hash and registers it with the code hash in `HashReg`
// it uses address to send the transaction.
// returns the content hash that we use to register a url
admin.register(primaryAccount, contract.address, contenthash)
// here you deploy ~/dapps/shared/contracts/test/info.json to a url
admin.registerUrl(primaryAccount, hash, url)
}
});
