Development help with Theme Sniffer

Theme Sniffer is a tool that helps reviewers and developers check the themes they are reviewing/developing against several coding standards.

The last stable version (0.1.5) is still using the old version of the WordPress Coding Standards, and a lot has changed since then. For close to a year now I’ve been working on upgrading the plugin a bit, and the new version is nearing completion.

The new version has updated codebase, updated coding standards (updated WPCS and added WPThemeReview standard as well), newer version of PHP_CodeSniffer which brings some performance updates and some other tweaks.
Even though the majority of the plugin is functional, it still has some issues.

This is where I need your help.

The new PHPCS has a different way of running the sniffer, using the Runner class and the Config class. For Theme Sniffer to perform the sniffing process it needs to write it’s own runner.

The issue I’m having is that some of the custom config settings are not working properly.
One way you can help is to see what could be the issue with this.

How to setup the development of the Theme Sniffer?

To start working on the development of the plugin you need to have a development environment. I’m using VVV, you can work on whatever works the best for you.

Steps to reproduce:

1. Go to your plugins folder and clone the repository

git clone

2. Go to the directory

cd theme-sniffer

3. Checkout development branch

git checkout development

4. Go to theme-sniffer folder and run composer install, npm install and npm run build (in that order)

5. Activate your plugin and test away

Anything you find you can report in the opened pull request, or in the slack #themereview channel.

Thank you!
