Imbo Coding Standard

This is the PHP coding standard for the Imbo project and all related tools. The ruleset is enforced using the PHP Coding Standards Fixer tool.

How to setup

First, add this package as a development dependency:

composer require --dev imbo/imbo-coding-standard ^2.0

then, create a PHP-CS-Fixer configuration file named .php-cs-fixer.php local to your repository that includes the following:

<?php declare(strict_types=1);
require 'vendor/autoload.php';

$finder = (new Symfony\Component\Finder\Finder())
    ->files()
    ->name('*.php')
    ->in(__DIR__)
    ->exclude('vendor');

return (new Imbo\CodingStandard\Config())
    ->setFinder($finder);

Adjust the paths if necessary. Now you can run the following command to check the coding standard in your project:

php-cs-fixer fix --dry-run --diff

You can install the php-cs-fixer tool globally with Composer if you so wish:

composer global require friendsofphp/php-cs-fixer

Refer to the documentation for other installation alternatives.

Add step in the GitHub workflow

All Imbo-related projects use GitHub workflows, and checking the coding standard should be a part of that workflow:

name: CI workflow
on: push
jobs:
  php-cs-fixer:
    runs-on: ubuntu-20.04
    name: Check coding standard
    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Setup PHP
        uses: shivammathur/setup-php@v2
        with:
          tools: php-cs-fixer

      - name: Install dependencies
        run: composer install --prefer-dist

      - name: Check coding standard
        run: php-cs-fixer fix --dry-run --diff
