The skeleton repository contains an
.editorconfig file at the root. This is used for unifying the coding style for different editors and IDEs, as defined at https://editorconfig.org/.
The file is a recommendation but not a requirement. Customers are welcome to modify or remove as needed based on their team’s needs.
The default content matches the editor configuration used by WordPress core (other than the removal of one file reference that is specific to WordPress core). This helps customers to write code that has a compatible code style to that found in WordPress core, and many themes and plugins.
The use of PHP_CodeSniffer and the WordPress Coding Standards will further help with code style for the many items that are outside of the EditorConfig standard.
