Install Coder with Drush
First, make sure Drush is installed correctly:
If you get drush not found or similar, follow Drush's installation instructions.
Now install Coder to Drush's central store:
drush pm-download coder --destination=$HOME/.drush
Clear drush's internal cache so it sees Coder:
drush cache-clear drush
Note that Drush stored Coder's folder inside a hidden .drush folder in your home directory (e.g.: if your username is mparker17 and you use Linux, then Coder will be at /home/mparker17/.drush/coder). You'll need the path to Coder shortly.
Install CodeSniffer with PEAR
First, make sure PEAR is installed correctly:
If you get pear not found or similar, follow PEAR's installation instructions
Now install PHP CodeSniffer:
pear install PHP_CodeSniffer-1.4.2
Install CodeSniffer with Drush
If you've installed Coder through Drush, you can get Drush to install PHPCodeSniffer for you.
Test PHP Codesniffer was installed correctly
To do this, just run:
You should see something like PHP_CodeSniffer version 1.4.1 (stable) by Squiz (http://www.squiz.net). Depending on how you installed it, you may have to give the full path instead of simply phpcs.
Path for php code sniffer.
- sudo ln -sv /home/username/.coder/coder_sniffer/Drupal $(pear config-get php_dir)/PHP/CodeSniffer/Standards/Drupal
Running checks on a file or folder
phpcs --standard=Drupal /path/to/example.module
See also other usage examples for phpcbf etc. Of course that command is annoyingly long, so you can setup a shell alias (see below).
If you installed Coder with Drush, you can run:
drush drupalcs $file_or_folder_to_check
... where $file_or_folder_to_check is a path to a folder containing PHP / CSS / JS code to check against Drupal standards. You can use . to check the current directory.
If that doesn't work, or you didn't install Coder with Drush, you can run:
phpcs --standard=$path_to_coder_module/coder_sniffer/Drupal -- $file_or_folder_to_check
... where $path_to_coder_module is the path to Coder (e.g.: if your username is mparker17 and you use Linux, then it will be at /home/mparker17/.drush/coder)
