Range-v3 is an extension of the Standard Template Library that makes its iterators and algorithms more powerful by making them composable. Unlike other range-like solutions which, seek to do away with iterators, in range-v3 ranges are an abstraction layer on top of iterators.

This package provides a lightweight library for calculating the edit distance between two sequences and finding an optimal alignment path for transforming one sequence into another.

Kokkos-fft is an experimental FFT interface for the Kokkos C++ environment. It implements local interfaces between Kokkos and FFT libraries such as FFTW, cufft, hipfft (rocfft), and oneMKL. "Local" means not using MPI, or running within a single MPI process without knowing about MPI.

xsimd provides a unified means for using SIMD features for library authors. Namely, it enables manipulation of batches of numbers with the same arithmetic operators as for single values. It also provides accelerated implementation of common mathematical functions operating on batches.

Magic Enum offers static reflection of enums, with conversions to and from strings, iteration and related functionality.

The AWS Common Runtime (CRT) library provides a C++ wrapper implementation for the following AWS C libraries: aws-c-auth, aws-c-cal, aws-c-common, aws-c-compression, aws-c-event-stream, aws-c-http, aws-c-io, aws-c-mqtt, aws-checksums, and s2n.

c++-gsl contains functions and types that are suggested for use by the C++ Core Guidelines maintained by the Standard C++ Foundation.

Abseil is a collection of C++ library code designed to augment the C++ standard library. The Abseil library code is collected from Google's C++ code base.

cpp-httplib is a C++11 single-file cross platform blocking HTTP/HTTPS library, easy to setup. It can also be used as a single-header library.

SObjectizer is a cross-platform "actor frameworks" for C++. SObjectizer supports not only the Actor Model but also the Publish-Subscribe Model and CSP-like channels. The goal of SObjectizer is to simplify development of concurrent and multithreaded applications in C++.

Lager is a library for value-oriented design implementing the unidirectional data-flow architecture. Apart from a store and various event loops it also provides lenses and cursors.

expected lite is a single-file header-only library for objects that either represent a valid value or an error that can be passed by value. It is intended for use with C++11 and later. The library is based on the std::expected proposal (http://wg21.link/p0323).

This package provides the following implementations of std::function:

• copyable fu2::function

• move-only fu2::unique_function (capable of holding move only types)

• non-owning fu2::function_view (capable of referencing callables in a non owning way)

This package provides a C++ implementation of several hash map and a hash set variants using open addressing and hopscotch hashing to resolve collisions. It is intended to be fast and provides additional features, such as heterogeneous lookups and different growth policies.

Optional lite is a single-file header-only library to represent optional (nullable) objects and pass them by value. The library aims to provide a C++17-like optional for use with C++98 and later. If available, std::optional is used.

This package provides the default libSwell.colortheme file for programs that use swell.

PlutoSVG is a compact and efficient SVG rendering library written in C. It is specifically designed for parsing and rendering SVG documents embedded in OpenType fonts, providing an optimal balance between speed and minimal memory usage. It is also suitable for rendering scalable icons.

This package provides a simple S-Expression parser for C++.

This is a simple C++ library that facilitates parsing command line arguments in a type independent manner.

This package provides a simple gettext replacement that works directly on .po files and doesn't need .mo files pre-generated.

This package provides a reference implementation of std::jthread, a cooperatively interruptible thread that is joined upon destruction.

This package provides a library that portably invokes native file open, folder select and file save dialogs. It allows the specification of a default file name and location, as well as filters with friendly names (such as "source files" or "image files") where supported.

nlohmann::json is a C++ JSON library that provides intuitive syntax and trivial integration.

Abseil is a collection of C++ library code designed to augment the C++ standard library. The Abseil library code is collected from Google's C++ code base.
