Pre-processor tools for the Solidity contract programming language

Aurum

Pre-processor goodness for Solidity

Aurum is a small tool to simplify Solidity programming.

Overview and Usage

Aurum adds #include and #require in Solidity code to reference inherited contracts and external contracts.

Turn monolithic contract files like this:

contract ExternalContract{function someFunction();}

contract Foobarbaz {
  address owner;
  uint somevalue;

  function Foobarbaz() {
    owner = msg.sender;
    somevalue = 31337;
  }
}


contract Foobar is Foobarbaz {

   function callExternal(address eca) {

     ExternalContract ec = ExternalContract(eca);
     ec.someFunction();
   }
}

contract Foobarfizz is Foobarbaz {

}

Into this:

Foobar.aur

#include [Foobarbaz]
#require [ExternalContract]

contract Foobar is Foobarbaz {

   function callExternal(address eca) {

     ExternalContract ec = ExternalContract(eca);
     ec.someFunction();
   }
}

Foobarbaz.lau

contract Foobarbaz {
  address owner;
  uint somevalue;

  function Foobarbaz() {
    owner = msg.sender;
    somevalue = 31337;
  }
}

ExternalContract.aur

contract ExternalContract {
  function someFunction() {

  }
}
