Local Development

If you have come looking for a way to set up your local development environment and use Tide to audit your plugins and themes, that is not a good use case for the platform. A better option would be to install a few Composer packages and run the same code sniffers Tide does. The easiest way would be to add these two files to the root directory inside your plugin or theme.


Create a composer.json file in the project root, and add this code.

  "require-dev": {
    "dealerdirect/phpcodesniffer-composer-installer": "*",
    "phpcompatibility/phpcompatibility-wp": "*",
    "wp-coding-standards/wpcs": "*",
  "scripts": {
    "phpcs": [
      "./vendor/bin/phpcs ${1:.} --standard=.phpcs.ruleset.xml"
    "phpcbf": [
      "./vendor/bin/phpcbf ${1:.} --standard=.phpcs.ruleset.xml"

Install the Composer dependencies:

composer install

PHPCS Ruleset

Create a .phpcs.ruleset.xml file in the project root, add this code, and replace the {{NAME}} and {{SLUG}} with your plugin or theme's name and slug.

<?xml version="1.0"?>
<ruleset name="{{NAME}}">
    <description>Custom ruleset for the {{NAME}} plugin.</description>

Run the PHP Code Sniffer on every file:

composer phpcs

Run the PHP Code Sniffer on a single file:

composer phpcs filename.php

Run PHP Code Beautifier on every file:

composer phpcbf

Run PHP Code Beautifier on a single file:

composer phpcbf filename.php

If you get an error when running these commands see the Help page.
