Laravel-Excel is an integration library for importing and exporting spreadsheet data between Laravel applications and Excel or CSV files. It provides a suite of tools for bidirectional spreadsheet integration, including a system for reading workbooks and mapping data into database models. The library distinguishes itself through a background processing system that handles large imports and exports using chunking and job queues. It supports template-driven exports by converting HTML tables from view templates into spreadsheet cells. The toolset covers broad capabilities for large dataset proc

Reactor Core ist ein Toolkit für reaktive Programmierung und eine nicht-blockierende Grundlage für die Komposition asynchroner Datenpipelines auf der JVM. Es dient als Framework für asynchrone Stream-Verarbeitung und als Backpressure-Managementsystem, das es Entwicklern ermöglicht, Ereignissequenzen zu transformieren, zu filtern und zu kombinieren, während der Datenfluss zwischen Produzenten und Konsumenten reguliert wird, um Ressourcenerschöpfung zu vermeiden. Die Bibliothek differenziert sich durch ein ausgeklügeltes Concurrency-Scheduling-System und nachfragebasierte Flusskontrolle. Sie entkoppelt die Signalverarbeitung von spezifischen Threads unter Verwendung einer Scheduler-Registry und bietet Mechanismen für die kontextbewusste Propagierung unveränderlicher Metadaten über asynchrone Grenzen hinweg. Sie enthält zudem spezialisierte Tools für die Trace-Erfassung zur Assembly-Zeit und Virtual-Time-Scheduling, um das Testen zeitbasierter Operatoren zu erleichtern. Das Projekt deckt ein breites Spektrum an Funktionen ab, einschließlich funktionaler Datenverarbeitung für Sequenzaggregation und Windowing, einer Vielzahl von Fehlerbehebungsstrategien wie exponentiellem Backoff-Retry sowie Dienstprogrammen zur Überbrückung von Legacy-Callback- oder synchronen APIs in reaktive Streams. Zudem bietet es Instrumentierung für Pipeline-Monitoring und eine Suite von Test-Tools zur Verifizierung von Signalsequenzen.

coobjc is an Objective-C coroutine library that provides await methods and generators to simplify asynchronous programming in Objective-C and Swift. It enables the implementation of non-blocking workflows to eliminate nested callbacks and thread blocking. The toolkit includes a non-blocking Foundation wrapper to convert synchronous Foundation and UIKit APIs into suspendable operations. It provides a lazy sequence generator for producing values on demand via yield, as well as a channel-based communication tool for exchanging data between concurrent tasks using buffered and unbuffered channels.

MoreLINQ is a functional programming toolkit and extension library for .NET that augments LINQ to Objects with advanced operators for sequence manipulation and analysis. It provides a set of tools for declarative data transformation, leveraging lazy evaluation and composition to handle complex object sequences. The library is distinguished by its specialized capabilities for combinatorial generation, including the production of permutations, subsets, and Cartesian products. It also provides advanced sequence joining options, such as full, left, and right outer joins, and supports complex data

cppcoro is a C++ coroutine library and concurrency toolkit providing primitives for asynchronous tasks, lazy generators, and non-blocking execution. It functions as an asynchronous I/O framework for managing network sockets and file operations through an event loop. The library features a work-stealing thread pool for distributing tasks across multiple cores and a set of async generators for producing lazy sequences of values both synchronously and asynchronously. It includes a concurrency toolkit with async mutexes, latches, and shared tasks to coordinate multi-threaded execution. Its capab
