Brew install php cs fixer

To set up php linting, you’ll want to install this PHP CodeSniffer repo and configure with this WordPress Coding Standards repo: . There are a number of ways to do this, whether direct download, Composer, Homebrew, Pear, etc. The following is what works for me on MacOS using Homebrew:

In a terminal window on your Mac, start by updating your Homebrew.

brew doctor

Then install the Code Sniffer:

brew install php-code-sniffer

After that is done, you should be able to check that things installed correctly.

phpcs -i

will show you the Standards that you have installed. You will probably see something like:

The installed coding standards are MySource, PEAR, PSR1, PSR12, PSR2, Squiz, Zend

Once we see the installed standards, we can then download the WordPress Coding Standards. I usually just clone the repo to a directory in the root of my computer, but you can put it anywhere you like, assuming you’ll remember the path.

git clone https://github.com/WordPress-Coding-Standards/WordPress-Coding-Standards.git ~/wpcs

After that is downloaded, you’ll need to tell phpcs where to find the new coding standards. Assuming you downloaded the repo to the folder above, you can enter:

phpcs --config-set installed_paths ~/wpcs

Otherwise, you will need to point to whereever you intalled your WordPress Coding Standards.

Now that you've told phpcs where to find the xml files for WordPress Coding Standards, you can check to see that they are properly found:

phpcs -i

and now you should see:

The installed coding standards are MySource, PEAR, PSR1, PSR12, PSR2, Squiz, Zend, WordPress, WordPress-Extra, WordPress-Docs and WordPress-Core

composer global require "squizlabs/php_codesniffer=*"
phpcs --version

To lint the php files in a folder

phpcbf --extensions=php --standard=WordPress -v ./my-plugin-folder
