truffle-flatten

Thanks to Nomic Labs for the heavy lifting.

This truffle plugin does very little in addition to what the base tool Nomic Labs has provided.

• It extracts all pragmas to the top of the flattened file
• the highest pragma version is selected
• saves the flattened source into flatten/Flattened.sol

Installation

1. Install the plugin with npm

   npm install truffle-flatten
   

2. Add the plugin to your truffle.js or truffle-config.js file

   module.exports = {
     /* ... rest of truffle-config */
   
     plugins: [
       'truffle-flatten'
     ]
   }

Usage

truffle run flatten <Source.sol>
