Hardhat plugin to find compiler outputs of contracts.

What

This plugin will help you with reviews and implementations by giving compiler outputs of contracts.

npm install hardhat-finder

Install the plugin via yarn:

yarn add hardhat-finder

Import the plugin in your hardhat.config.js:

require("hardhat-finder");

Or if you are using TypeScript, in your hardhat.config.ts:

import "hardhat-finder";

Tasks

This plugin adds the finder task to Hardhat:

Usage: hardhat [GLOBAL OPTIONS] finder [--colorify] [--compact] [--depth <INT>] [--include-dependencies] [--max-string-length <INT>] [--name <STRING>] [--no-compile] [--path <INPUTFILE>] [--prettify] [...outputs]
$ hardhat finder --prettify --colorify contracts/Example.sol Example abi bytecode

Environment extensions

This plugin extends the Hardhat Runtime Environment by adding an finder field whose type is Finder.

Configuration

This plugin extends the HardhatUserConfig's FinderUserConfig object with the finder field.

This is an example of how to set it:

module.exports = {
  finder: {
    contract: {
      path: "contracts/Example.sol",
      name: "Example",
    },
    outputs: [
      "metadata",
      "storage-layout",
      "dependencies-info",
      "source-code",
      "fully-qualified-name",
      "method-identifiers",
    ],
    depth: Infinity,
    maxStringLength: Infinity,
    includeDependencies: false,
    colorify: false,
    prettify: false,
    compact: false,
    noCompile: false,
    runOnCompile: false,
  },
};
Option Type Default Description
outputs String[] ["artifact", "build-info", "abi", "metadata", "bytecode", "bytecode-runtime", "link-references", "link-references-runtime", "immutable-references", "immutable-references-runtime", "source-code", "dependencies-source-code", "dependencies-info", "settings", "solc-version", "ast", "method-identifiers", "opcodes", "opcodes-runtime", "storage-layout", "fully-qualified-name", "developer-document", "user-document", "generated-sources", "generated-sources-runtime", "source-map", "source-map-runtime"] Types of output the contract wants to print.
depth Number Infinity The maximum number of nested JSON objects to be printed in outputs.
maxStringLength Number Infinity The maximum number of string lengths to be printed in outputs.
includeDependencies Boolean false Include contract dependencies in outputs.
colorify Boolean false Colorize the outputs.
prettify Boolean false Beautify the outputs.
compact Boolean false Compact the outputs.
noCompile Boolean false Don't compile before running this task.
runOnCompile Boolean false Run finder task during compile task.

Usage

There are no additional steps you need to take for this plugin to work.

Install it and access finder through the Hardhat Runtime Environment anywhere you need it (tasks, scripts, tests, etc).

import { finder } from "hardhat";

async function main() {
  const contractPath = "contracts/ExampleLibrary.sol";
  const contractName = "ExampleLibrary";
  await finder.setFor({
    contractPath,
    contractName,
  });

  console.log(finder.getUserDocument());
  console.log(finder.getDeveloperDocument());
}
