Mkinterface NPM

MkInterface

A tool for lazy guys to update all interfaces of smart contracts at once.

Installation

npm install -g mkinterface

This tool required truffle, make sure you've already got it.

npm install -g truffle

Configuration

This version had supported solidity compiler 0.5.0 and truffle 5.0.0. To esablishing new feature, we need you to create mkinterface.json in the root of your project.

E.g

{
  "minVersion": "0.4.11",
  "maxVersion": "0.6.0",
  "supportSolc5": true
}

Version configuration

mkinterface will find all .sol files, then update old style of pragma to the new one.

E.g.

Configuration	Before	After
`{"minVersion": "0.4.11","maxVersion": "0.6.0"}`	`pragma solidity ^0.4.3;`	`pragma solidity >= 0.4.11 <= 0.6.0;`
`{"minVersion": "0.4.11", "supportSolc5": true}`	`pragma solidity ^0.4.3;`	`pragma solidity >= 0.4.11;`
`{"minVersion": "0.4.11", "supportSolc5": false}`	`pragma solidity ^0.4.3;`	`pragma solidity ^0.4.11;`
`{}`	`pragma solidity ^0.4.3;`	`pragma solidity ^0.4.3;`

Solc compatible

New version of solc have some changes, old version of contract's interface won't work properly.

E.g.

function readProposal(uint256 _id) public view returns (bytes);

Result of truffle compile all

MyContractInterface.sol:13:65: TypeError: Data location must be "memory" for return parameter in function, but none was given.
    function readProposal(uint256 _id) public view returns (bytes);
                                                            ^---^

supportSolc5: true will change interface into:

function readProposal(uint256 _id) public view returns (bytes memory);

Expected result:

pragma solidity >= 0.4.24 <= 0.6.0;


contract MigrationsInterface {
  //Events
  
  //Public methods
  function last_completed_migration() public view returns (uint256);
  function owner() public view returns (address);
  function setCompleted(uint256  completed) public;
  function upgrade(address  new_address) public;
  function test(bytes memory  data, uint256[] memory  dis) public returns (string memory);
}
