These links are converted to internal TYPO3 links (`t3://page...`, `t3://file...`). Installation and configuration ------------------------------ [](#installation-and-configuration) To install the extension, use Composer: ``` composer require plan2net/link-alchemy ``` No configuration is required. The extension automatically hooks into the DataHandler for TCA fields and into the RTE content transformation process. Compatibility ------------- [](#compatibility) Versions 12.0.0 and higher are compatible with the corresponding TYPO3 versions. If you already overwrite the class `RteHtmlParser` in your project, you may need to adjust the XCLASS configuration in `ext_localconf.php`. Usage ----- [](#usage) The extension automatically hooks into the RTE content transformation process. No additional setup is required. When RTE content is processed, external links that refer to internal pages or files will be rewritten to use TYPO3's internal link format. Example ------- [](#example) Here is an example of how the extension transforms a link in an RTE text field: - **Before**: `Link` - **After**: `Link` This ensures that links are correctly handled within the TYPO3 CMS environment, providing better integration and consistency. Internals --------- [](#internals) ### `Plan2net\LinkAlchemy\Xclass\RteHtmlParser` [](#plan2netlinkalchemyxclassrtehtmlparser) This class extends the core `RteHtmlParser` to include custom transformations for internal links. ### `Plan2net\LinkAlchemy\Hooks\DataHandlerHook` [](#plan2netlinkalchemyhooksdatahandlerhook) This class handles the transformation of internal links within TCA `type=link` fields. ### `Plan2net\LinkAlchemy\RteTransformation\InternalLinkTransformation` [](#plan2netlinkalchemyrtetransformationinternallinktransformation) This class handles the transformation of internal links within the RTE content. ### `Plan2net\LinkAlchemy\Service\UrlParser` [](#plan2netlinkalchemyserviceurlparser) This class parses the urls to internal links. TODO ---- [](#todo) - Unit-Tests for UrlParser Acknowledgements ================ [](#acknowledgements) This extension was inspired by [Georg Ringers](https://github.com/georgringer)'s uri2link extension that only transforms TCA `type=link` fields. ### Health Score 47 — FairBetter than 93% of packages Maintenance84 Actively maintained with recent releases Popularity28 Limited adoption so far Community10 Small or concentrated contributor base Maturity54 Maturing project, gaining track record Bus Factor1 Top contributor holds 96.2% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
