solidity-upgrade

This is a work in progress Prettier Plugin for Refactoring Solidity 0.4.x code to 0.5.x code. This tool does the following tasks currently:

Change pragma version to ^0.5.0.
Add calldata storage keyword infront of external function parameters and memory infront of other function's parameters that don't already have a defined parameter storage location.

Installation

Install both prettier and solidity-refactor:

npm install --save-dev prettier solidity-refactor

This plugin allows you to configure prettier to your needs. Command with my personal config is

prettier --write --tab-width 4 --print-width 140 '**/*.sol'
