I'm new to write a smart contract with Ethereum.
According to an official document, compiling a smart contract needs to remove all the line of a source code of the contract like:
var greeterSource = 'contract mortal { address owner; function mortal() { owner = msg.sender; } function kill() { if (msg.sender == owner) suicide(owner); } } contract greeter is mortal { string greeting; function greeter(string _greeting) public { greeting = _greeting; } function greet() constant returns (string) { return greeting; } }'
var greeterCompiled = web3.eth.compile.solidity(greeterSource)
https://ethereum.gitbooks.io/frontier-guide/content/contract_greeter.htmlAs I think the removing process is not *smart*, I want to compile the code itself like:
var greeterCompiled = web3.eth.compile.solidity_infile( "greeter.txt" )
# The function "solidity_infile" does not exists actually,
# but represents what I want to do.
**greeter.txt**
contract
mortal {
/* Define variable owner of the type address*/
address owner;
/* this function is executed at initialization and sets the owner of the contract */
function mortal() { owner = msg.sender; }
/* Function to recover the funds on the contract */
function kill() { if (msg.sender == owner) suicide(owner); }
}
contract greeter is mortal {
/* define variable greeting of the type string */
string greeting;
/* this runs when the contract is executed */
function greeter(string _greeting) public {
greeting = _greeting;
}
/* main function */
function greet() constant returns (string) {
return greeting;
}
}
Does anyone how to do that?
The compiler I'm using is Solidity.

Please try the following on mac. It'll make the contract into the one line.
$ cat input_filename_here | tr -d '\n' > output_filename_here
