license

This project provides a composer package with an abstraction of an open-source license.

Installation

Run

composer require --dev ergebnis/license

Usage

Sometimes open source maintainers complain about the burden of managing an open-source project. Sometimes they argue that contributors opening pull requests to update license years unnecessarily increase their workload.

Of course, all of this can be automated, can't it?

Configuration for friendsofphp/php-cs-fixer

With friendsofphp/php-cs-fixer you can use the configuration file .php-cs-fixer.php to

• save the license to a file, e.g. LICENSE or LICENSE.md
• specify a file-level header using the header_comment fixer that will be replaced in PHP files

Here's an example of a .php-cs-fixer.php file for an open-source project using the MIT license type:

<?php

declare(strict_types=1);

/**
 * Copyright (c) 2020-2022 Andreas Möller
 *
 * For the full copyright and license information, please view
 * the LICENSE.md file that was distributed with this source code.
 *
 * @see https://github.com/ergebnis/license
 */

use Ergebnis\License;
use PhpCsFixer\Config;
use PhpCsFixer\Finder;

$license = License\Type\MIT::text(
    __DIR__ . '/LICENSE',
    License\Range::since(
        License\Year::fromString('2020'),
        new DateTimeZone('UTC')
    ),
    License\Holder::fromString('Andreas Möller'),
    License\Url::fromString('https://github.com/ergebnis/license')
);

$license->save();

$finder = Finder::create()->in(__DIR__);

return Config::create()
    ->setFinder($finder)
    ->setRules([
        'header_comment' => [
            'comment_type' => 'PHPDoc',
            'header' => $license->header(),
            'location' => 'after_declare_strict',
            'separate' => 'both',
        ],
    ]);

💡 Also take a look at .php-cs-fixer.php of this project.

Here's an example of a .php-cs-fixer.php file for a closed-source project using the None license type:

<?php

declare(strict_types=1);

/**
 * Copyright (c) 2011-2019 Andreas Möller
 *
 * @see https://github.com/localheinz/localheinz.com
 */

use Ergebnis\License;
use PhpCsFixer\Config;
use PhpCsFixer\Finder;

$license = License\Type\None::text(
    License\Range::since(
        License\Year::fromString('2020'),
        new DateTimeZone('UTC')
    ),
    License\Holder::fromString('Andreas Möller'),
    License\Url::fromString('https://github.com/localheinz/localheinz.com')
);

$finder = Finder::create()->in(__DIR__);

return Config::create()
    ->setFinder($finder)
    ->setRules([
        'header_comment' => [
            'comment_type' => 'PHPDoc',
            'header' => $license->header(),
            'location' => 'after_declare_strict',
            'separate' => 'both',
        ],
    ]);

GitHub Actions

When using GitHub Actions, you can set up a scheduled workflow that opens a pull request to the license year automatically on January 1st:

name: "License"

on:
  schedule:
    - cron: "1 0 1 1 *"

jobs:
  license:
    name: "License"

    runs-on: "ubuntu-latest"

    steps:
      - name: "Checkout"
        uses: "actions/checkout@v2.0.0"

      - name: "Install dependencies with composer"
        run: "composer install --no-interaction --no-progress --no-suggest"

      - name: "Run friendsofphp/php-cs-fixer"
        run: "vendor/bin/php-cs-fixer fix --config=.php-cs-fixer.php --diff --dry-run --verbose"

      - name: "Open pull request updating license year"
        uses: "gr2m/create-or-update-pull-request-action@v1.2.9"
        with:
          author: "Andreas Möller <am@localheinz.com>"
          branch: "feature/license-year"
          body: |
            This PR

            - [x] updates the license year
          commit-message: "Enhancement: Update license year"
          path: "."
          title: "Enhancement: Update license year"
        env:
          GITHUB_TOKEN: "${{ secrets.GITHUB_TOKEN }}"

💡 See crontab.guru if you need help scheduling the workflow.

Note that pull requests opened or commits pushed by GitHub Actions will not trigger a build. As an alternative, you can set up a bot user:

       - name: "Open pull request updating license year"
         uses: "gr2m/create-or-update-pull-request-action@v1.2.9"
         with:
-          author: "Andreas Möller <am@localheinz.com>"
+          author: "ergebnis-bot <bot@ergebn.is>"
           branch: "feature/license-year"
           body: |
             This PR

             - [x] updates the license year
           commit-message: "Enhancement: Update license year"
           path: "."
           title: "Enhancement: Update license year"
         env:
-          GITHUB_TOKEN: "${{ secrets.GITHUB_TOKEN }}"
+          GITHUB_TOKEN: "${{ secrets.ERGEBNIS_BOT_TOKEN }}"
