Check Drupal code for deprecations and discover bugs via static analysis
Built on PHPStan, this static analysis tool will check for correctness (e.g. using a class that doesn't exist), deprecation errors, and more.
Why? While there are many static analysis tools out there, none of them run with the Drupal context in mind. This allows checking contrib modules for deprecation errors thrown by core.

You can install this in your project using Composer as a development dependency like so:
composer require mglaman/drupal-check --dev
You can also install this globally using Composer like so:
composer global require mglaman/drupal-check
Refer to Composer's documentation on how to ensure global binaries are in your PATH: https://getcomposer.org/doc/00-intro.md#manual-installation.
This tool works on all Drupal code, but must be executed within the root directory of a Drupal project..
You can run this tool within any Drupal project. But, for best results, create a fresh Drupal directory on the latest Drupal:
composer create-project drupal-composer/drupal-project:8.x-dev drupal --no-interaction --stability=dev cd drupal
drupal-check [OPTIONS] [DIRS]
OPTIONS- See "Options" for allowed values. Specify multiples in sequence, e.g.
DIRS- One or more directories within the root of a Drupal project.
-dCheck deprecations (default)
-eExclude directories. Wildcards work. Separate multiple excluded directories with commas, no spaces. e.g.: */tests/codeception/acceptance/*.php
--drupal-rootPath to Drupal root. Fallback option if drupal-check could not identify Drupal root from the provided path(s).
drupal-check -d web/modules/contrib/address
drupal-check -a web/modules/contrib/address
drupal-check -ad web/modules/contrib/address
