Unified
Unified ist eine Syntaxbaum-Verarbeitungs-Engine und ein Content-Ökosystem, das entwickelt wurde, um Textinhalte zu parsen, zu transformieren und zu serialisieren. Es fungiert als Plugin-basierte Content-Pipeline, die Rohtext in strukturierte abstrakte Syntaxbäume (ASTs) unter Verwendung einfacher JavaScript-Objekte für die programmatische Inspektion und Modifikation konvertiert.
Das Projekt zeichnet sich durch eine modulare Architektur aus, die eine ökosystemübergreifende Übersetzung ermöglicht, wodurch Syntaxbäume zwischen verschiedenen Spezifikationen wie HTML und Markdown konvertiert werden können. Es nutzt ein System aus unveränderlichem Prozessor-Cloning und geteilten Zustandscontainern, wodurch sichergestellt wird, dass Verarbeitungspipelines erweitert und angepasst werden können, ohne die ursprünglichen Konfigurationen zu verändern.
Das System bietet umfassende Funktionen für das Syntaxbaum-Management, einschließlich Depth-First-Traversierung, CSS-basierter Knotenauswahl und rekursiver Transformationen. Die Verarbeitungsoberfläche erstreckt sich auf die Analyse natürlicher Sprache, das Parsen von GitHub Flavored Markdown und die Abbildung von Syntaxbäumen auf virtuelle DOM-Elemente für die Browser-Visualisierung.
Die Verarbeitungslogik kann über Modul-Bundler oder CDNs in Webanwendungen integriert werden.
Features
