TYPO3 Coding Standards Package ============================== |Continuous Integration (CI)| |Core Synchronization| |Coverage Status| You know the feeling: You work on your own extension, and then contribute to TYPO3, and TYPO3 delivers all the nice things to check for proper coding standards. Well, same happens to all of us! Luckily, TYPO3 has this configuration in Core, and it’s now available separately - ready to plug-and-play for you! It does not matter if you’re an extension developer, or a TYPO3 contributor, or working on your TYPO3 project. Installation ------------ As this is a composer package, execute ``composer req --dev typo3/coding-standards`` in your composer project. What’s in the package? ---------------------- The coding guidelines that are used in TYPO3 Core development. Instead of putting this information in our main repository, it should be helpful to apply certain rules to other projects as well. TYPO3 is more than just TYPO3 Core! PHP-CS-Fixer rules ~~~~~~~~~~~~~~~~~~ Making sure your PHP files apply to the same rules. .editorconfig ~~~~~~~~~~~~~ If you work on a team, and you use different IDE settings, ``.editorconfig`` helps you to have the same settings across all editors. It does not matter if it is VS-Code, vim or PhpStorm. Setting up the TYPO3 rulesets as boilerplate ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Our coding standards file can set this up for you. Run .. code:: bash composer exec typo3-coding-standards project or .. code:: bash composer exec typo3-coding-standards extension or if you want to update the rules, use the ``-f`` option .. code:: bash composer exec -- typo3-coding-standards extension -f Have a look at the newly created files in your root folder: - .php-cs-fixer.php - .editorconfig For projects, the folder ``src`` is configured by default, but you can accommodate where your extensions or PHP code resides in. For extensions, PHP-CS-Fixer scans the whole base directory. In addition, you can configure your PHP-CS-Fixer cache file folder and other configurations just like with PHP-CS-Fixer. You can decide to commit them to your Git repository, which is the recommended way. Executing the PHP-CS-Fixer -------------------------- Once you’ve followed the step above, running PHP CS Fixer works like this: .. code:: bash composer exec php-cs-fixer Leave a note on how you set it up on GitHub Actions or GitLab CI/CD so this document can be even more helpful for everybody. What’s next? ------------ We’d love to ship out license headers for all PHP files, however there are certain limitations (namespace must be underneath the license headers), which why this option is not enabled by default. A note about our standards -------------------------- PHP Coding Guidelines ~~~~~~~~~~~~~~~~~~~~~ TYPO3’s coding guidelines have evolved over time. And we are happy to have PHP-FIG and PSR-1/PSR-2 and PSR-12. That’s why we’re committed to following these guidelines. However, there are some more rules that we think are good: - Remove leading slashes in use clauses. - PHP single-line arrays should not have trailing comma. - Single-line whitespace before closing semicolon are prohibited. - Remove unused use statements in the PHP source code - Ensure Concatenation to have at least one whitespace around - Remove trailing whitespace at the end of blank lines. Video Tutorial -------------- |TYPO3-Tutorial - The TYPO3 Coding Standards Package| Maintaining and Development of this package ------------------------------------------- This package is not meant to be updated regularly, since talking about coding guidelines takes a lot of time, and is usual a matter of taste. Nonetheless, you can always open up an issue if you feel like we’re missing out on something. A GitHub action automatically synchronizes the files with the TYPO3 Core. Please do not open pull requests for these changes, but push your changes to the TYPO3 Core. Development ~~~~~~~~~~~ The source code comes with a DDEV Local configuration that makes using Composer and switching PHP versions very easy. For more information about DDEV, see the `documentation `__. In the ``composer.json`` many scripts are predefined to run the CI locally before you push erroneous changes. Additionally some fix commands are integrated. Manually update the files from the core ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The synchronization job is scheduled once per night. It can also be started manually on the ``Actions`` tab on GitHub by selecting ``Core Synchronization`` and running the workflow on the main branch. License & Thanks ---------------- This package is available under the MIT license, since it relies heavily on the PHP-CS-Fixer code. In addition, I would like to thank the TYPO3 Core Team that kickstarted this set of rules in 2015, and to the creators and maintainers of PHP-CS-Fixer package.
