language-ext is a functional programming framework for C# that provides a suite of immutable data structures and monadic types. It enables the implementation of pure functional programming patterns, utilizing containers to manage side effects, optional values, and error handling. The library is distinguished by its advanced concurrency and state management tools, including a software transactional memory system and lock-free atomic references. It also provides specialized utilities for distributed systems, such as vector clocks for causality tracking and deterministic data conflict resolution

re-frame ist ein funktionales Framework für den Bau von Single-Page-Anwendungen in ClojureScript. Es bietet eine zentralisierte, unveränderliche Datenbank, die als Single Source of Truth für den gesamten Anwendungszustand dient und einen strikten, unidirektionalen Datenfluss erzwingt, bei dem Events Zustandsübergänge und nachfolgende View-Updates auslösen. Das Framework zeichnet sich durch einen reaktiven Signal-Graphen und eine Interceptor-basierte Middleware-Pipeline aus. Indem Anwendungslogik als Sequenz datengetriebener Events und deklarativer Side-Effects behandelt wird, entkoppelt es die Geschäftslogik von der View-Schicht. Diese Architektur ermöglicht es Entwicklern, komplexe Zustandsübergänge und externe Operationen durch reine Funktionen zu verwalten, wobei sichergestellt wird, dass Side-Effects von einem separaten Interpreter statt durch imperative Aufrufe ausgeführt werden. Das System umfasst eine umfassende Suite an Funktionen für das Management der Anwendungsarchitektur, einschließlich reaktiver Datenableitung, abonnementbasierter View-Reconciliation und eventgesteuertem Zustandsmanagement. Es unterstützt fortgeschrittene Entwicklungs-Workflows wie Event-Tracing, State-Checkpointing und die Möglichkeit, Side-Effects für isolierte Tests zu stubben. Das Projekt ist für die Integration mit React konzipiert und nutzt Virtual-DOM-Reconciliation, um Benutzeroberflächen effizient zu aktualisieren. Es bietet ein robustes Set an Utilities für den Umgang mit Cross-Cutting Concerns, die Verwaltung komplexer Datenfluss-Graphen und die Koordination asynchroner Operationen innerhalb einer vorhersagbaren, sequenziellen Event-Pipeline.

Dieses Projekt ist ein CSS-Stylesheet-Compiler, der Sass-Quellcode in Standard-CSS umwandelt. Er bietet den primären Mechanismus für die Stilkonvertierung und implementiert Syntaxregeln für Webbrowser und Anwendungen. Der Compiler unterstützt ein modulbasiertes Abhängigkeitssystem, das dedizierte Namespaces für Kapselung nutzt und Kollisionen im globalen Scope verhindert. Er enthält spezialisierte Engines für die Konvertierung von Farbmodellen sowie fortgeschrittene mathematische Berechnungen, einschließlich Trigonometrie und Logarithmen. Die Funktionen decken eine breite Palette an Build- und Analyse-Tools ab, darunter die Generierung von Source Maps, Dateisystemüberwachung für automatische Neukompilierung sowie die Möglichkeit, die Kompilierung direkt im Webbrowser auszuführen.
