README

Hardhat SPDX License Identifer

Prepend Solidity source files in Hardhat projects with the SPDX License Identifier specified in package.json.

Versions of this plugin prior to 2.0.0 were released as buidler-spdx-license-identifier.

Installation

yarn add --dev hardhat-spdx-license-identifier

Usage

Load plugin in Hardhat config:

require('hardhat-spdx-license-identifier');

Add configuration under the spdxLicenseIdentifier key:

| option | description | default | |-|-|-| | overwrite | whether to overwrite existing SPDX license identifiers | false | | runOnCompile | whether to automatically prepend identifiers during compilation | false |

spdxLicenseIdentifier: {
  overwrite: true,
  runOnCompile: true,
}

The included Hardhat task may be run manually:

yarn run hardhat prepend-spdx-license

Files which do not contain a license identifier will be prepended with one. Files with a license identifier which does not match that which is specified in package.json may be updated, depending on configuration.
