# PHP CodeSniffer

Run phpcs on your custom modules

PHP CodeSniffer (<https://github.com/squizlabs/PHP\\_CodeSniffer>) is already included with our D8 project with composer. If you run a `lando composer install` you should have it available at `./vendor/bin/phpcs`

### Local Setup:

1\. You need to specifically download the Drupal coding standards using the coder module. You can do this globally for your computer by running:

```
composer global require drupal/coder:^8.3.1
```

2\. You need to make sure phpcs knows about your newly installed coding standard (note the path below assumes you're using Ubuntu, yours might be different on a mac):

```
./vendor/bin/phpcs --config-set installed_paths ~/.config/composer/vendor/drupal/coder/coder_sniffer/
```

3\. Now you can run this manually against your custom modules:

```
./vendor/bin/phpcs --standard=Drupal docroot/modules/custom/
```
