Installing and configuring codesniffer

Installing codesniffer in a development environment.¶ ↑

Path examples here are given for a current MAMP installation. Paths may vary on other installations, but the concepts remain valid. Ensure that PEAR is installed on your machine.

From the terminal running which pear will tell you where pear is installed on your machine. On a current MAMP installation this will be in

/Applications/MAMP/bin/php/php5.4.10/bin/pear .

It will simplify things for you if you create a symlink to the executable using

sudo ln -s /Applications/MAMP/bin/php/php5.4.10/bin/pear /usr/bin/pear

Running pear config_show will show the full pear configuration on your screen.

Install CodeSniffer ¶ ↑

Simply run pear ‘install PHP_CodeSniffer’ in a terminal window, and pear will install CodeSniffer on your machine. Run ‘pear config-get php_dir’ to see where your version of pear keeps the files it retrieves. On a current MAMP setup this will be in /Applications/MAMP/bin/php/php5.4.10/share/pear

Add this directory to the path in your php.ini file.

include_path = ".:/Applications/MAMP/bin/php/php5.4.10/share/pear"

CodeSniffer will be easier to use if you add a symlink for this executable as well.

sudo ln -s /Applications/MAMP/bin/php/php5.4.10/bin/phpcs /usr/bin/phpcs.

You can test your installation by typing

phpcs --version

Customizing for Drupal

The final step is to make the Drupal standard available to codesniffer. The standard can be downloaded here ftp.drupal.org/files/projects/drupalcs-7.x-1.x-dev.tar.gz . Uncompress the folder and place it with the default standards supplied by CodeSniffer. To find the directory navigate to the directory identified by running ‘pear config-get php_dir’, then navigate down to PHP/CodeSniffer/Standards. On the current MAMP setup this is /Applications/MAMP/bin/php/php5.4.10/share/pear/PHP/CodeSniffer/Standards
