The TutsPlus.com site has posted the next part of their series showing the use of the PHP CodeSniffer tool with WordPress. In the first part of the series they introduced "code smells" and build on that in part two with the installation and use of PHP CodeSniffer to detect these smells.
In the first article of this series, we defined code smells and looked at a few examples of what they are and how we may refactor them so the quality of the code is improved.
[…] Ultimately, we’re working towards implementing WordPress-specific code sniffing rules, but before we do that it’s important to familiarize yourself with PHP CodeSniffer. In this article, we’re going to take a look at what PHP CodeSniffer is, how to install it, how to run it against an example script, and how to refactor said script. Then we’ll look at how we’re going to move forward into WordPress-specific code.
The tutorial then shows you how to get the tool installed using Composer, not the PEAR method. They help you install Composer then create the simple project with a
composer.json configuration file defining the dependency. They provide a sample bit of code to run the analysis against and an example of the output showing violations of the coding standard.
