• Installation
• Configuration
• Usage
• Fix your code
• Ci
• Baseline

Installation

composer require --dev smile/magento2-smilelab-quality-suite

Configuration

Create three files at the root of your project directory:

• phpcs.xml.dist (example)
• phpmd.xml.dist (example)
• phpstan.neon.dist (example)

Usage

# Check registered vulnerabilities
composer audit

# Analyse php syntax
vendor/bin/parallel-lint --exclude vendor [src path]

# Analyse code style
vendor/bin/phpcs

# Analyse code complexity
vendor/bin/phpmd [src path] text phpmd.xml.dist

# Analyse code logic
vendor/bin/phpstan analyse

Fix your code

A lot of style errors can be fixed automatically by running this command:

vendor/bin/phpcbf --extensions=php,phtml

CI

GitLab Runner

Example of .gitlab-ci.yml file:

  - 'composer install'

sniffers:
    variables:
        COMPOSER_AUTH: $COMPOSER_AUTH
    script:
        - 'composer audit --format=plain'
        - 'vendor/bin/parallel-lint --exclude vendor [src path]'
        - 'vendor/bin/phpcs --extensions=php,phtml'
        - 'vendor/bin/phpmd [src path] text phpmd.xml.dist'
        - 'vendor/bin/phpstan analyse'
    tags:
        - 'php81'

Baseline

If you want to add this coding standard on an existing project, it might be complicated to fix all issues. The baseline is a mechanism that allows you to keep your legacy code as it is and enforces the quality analysis for the code you will add in the future.

❗ It is always better to fix all issues. Baseline are a tweak to help you have a fresh start. But keep in mind that all errors (in the baseline or not) must be corrected eventually.

To generate the baselines, run these commands:

# PHPCS
composer require --dev digitalrevolution/php-codesniffer-baseline
vendor/bin/phpcs --report=\\DR\\CodeSnifferBaseline\\Reports\\Baseline --report-file=phpcs.baseline.xml --extensions=php,phtml

# PHPMD
vendor/bin/phpmd app ansi phpmd.xml.dist --generate-baseline

# PHPSTAN
vendor/bin/phpstan analyse --generate-baseline

For phpstan, you'll need to add the file phpstan-baseline.neon to the include part of the phpstan.neon.dist file and config reportUnmatchedIgnoredErrors: false to the parameters part of the same file.

The baseline files must be added to git.
