A simply Solidity library for common string operations.
Install

Usage
To write your custom contracts, import it and attach it to the string type:

import 'solidity-string-util/contracts/StringUtil.sol';
contract YourContract {
using StringUtil for string;
// your custom code
}
You need an ethereum development framework for the above import statements to work! Check out these guides for Truffle, Embark or Buidler.
