About

Our goal is to provide an automated migration for TYPO3 updates.

This should include source code modifications like adjusting old legacy class names to new ones.

Requirements

• composer needs to be installed and inside your $PATH.

Installation

Run:

make install

and copy the vendor/composer/autoload_classaliasmap.php generated by composer in your TYPO3 installation to LegacyClassnames.php in the root of this project.

Usage

Run:

./vendor/bin/phpcbf <path>

This will run the auto fixer recursive for <path> fixing all issues.

Afterwards you should run:

./vendor/bin/phpcs <path>

To get information about possible issues that were not autofixed.

What's included?

Currently we can migrate calls to old legacy class names of the TYPO3 core like Tx_Extbase... to new ones like \TYPO3\Extbase\.... This is done for:

• PHPDocuments, like Includes and annotations for IDEs.

• Inheritance like extends and implements.

• Static calls like t3lib_div:: to \TYPO3\Core\Utility\GeneralUtility.

• Static call also checks for ::class, as technically we just look before the ::.

• Typehints in methods and function like injects.

• instanceof checks.

• Inline comments for IDEs, e.g. /* @var $configurationManager Tx_Extbase_Configuration_ConfigurationManager */

• Instantiation through new.

• Instantiation through makeInstance. Only Classnames in Strings are supported, no ::class.

• Instantiation through ObjectManager, check afterwards as this is static and all function calls using get and create will be adjusted. Might be useful to exclude this sniff and run it separately. Only Classnames in Strings are supported, no ::class.

• use statements.

• catch of legacy class names.

• Convert old legacy class definitions in extensions to namespaces.

• Convert usage of previously converted class definitions. On first run the definition will be converted, on second run the usage. This is due to the fact, that PHPCS might find the definition after the usage, so please run twice.

  NOTE The configured file will be updated after each run, for each converted class, trait and interface definition. See options.

• Add missing vendor to plugin and module registrations and configurations. You might want to set this to non fixable and warning if you already provide the vendor inside a single Variable, together with your extension key, as this is not recognized. So the following will be recognized:

  • $_EXTKEY,
  • $VENDOR . $_EXTKEY,
  • 'VENDOR.' . $_EXTKEY,

  While the following will not:

  • $key = 'Vendor.' . $_EXTKEY;

Also we check for the following deprecated calls:

• Check for create on ObjectManager, which is "stupid" just all create calls are marked with a warning.

Beside the features above which are covered by phpcs and phpcbf, the following linting is also available to generate a report of possible issues and during coding throughphpcs: - Check for usage of removed functions. The functions are configured via yaml files. The location of them is configurable, default is inside the standard itself, and we try to deliver all information. For configuration options seeremovedFunctionConfigFiles. - Check for usage of removed constants. The constants are configured in same way as removed functions. For configuration options seeremovedConstantConfigFiles.
