tl::optional provides a single-header implementation of the std::optional for C++11/14/17, with support for monadic operations added in C++23.

This package provides a header-only single-file std::filesystem compatible helper library, based on the C++17 and C++20 specs, but implemented for C++11, C++14, C++17 or C++20.

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.

Taskflow is a C++ library for writing parallel and heterogeneous task programs.

libcppgenerate is a library for generating C++ code from C++.

This package provides header only C++ binary serialization library. It is designed around the networking requirements for real-time data delivery, especially for games.

This package contains an implementation of the parallel external-memory suffix array construction algorithm called pSAscan. The algorithm is based on the sequential external-memory suffix array construction algorithm called SAscan.

MFront is a code generator which translates a set of closely related domain specific languages into plain C++ on top of the TFEL library.

Zug is a C++ library providing transducers, that is, composable sequential transformations.

This package contains a C++11 multiple-producer-multiple-consumer lockless queues header library based on circular buffer with std::atomic.

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

This package provides a C++ library for utilities used across Hyprland ecosystem.

Kokkos Core implements a programming model in C++ for writing performance portable applications targeting all major HPC platforms. For that purpose it provides abstractions for both parallel execution of code and data management. Kokkos is designed to target complex node architectures with N-level memory hierarchies and multiple types of execution resources.

The Clipper library performs line & polygon clipping - intersection, union, difference & exclusive-or, and line & polygon offsetting. The library is based on Vatti's clipping algorithm.Note: This package is a major update of the original clipper library.

Rct is a set of C++ tools that provide nicer (more Qt-like) APIs on top of Standard Template Library (STL) classes.

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

The Parsing Expression Grammar Template Library (PEGTL) is a zero-dependency C++ header-only parser combinator library for creating parsers according to a Parsing Expression Grammar (PEG).

This package provides useful C++ classes and routines such as argument parser, IO and conversion utilities.

type_safe is a C++ header-only library which provides abstractions for defining more appropriate types, thus allowing C++'s type system to prevent more bugs.

This package provides a header-only implementation of std::variant (formerly boost::variant) for C++11/14.

SWELL is a Windows emulation Layer. It provides a set of common APIs, common controls and win32-style extensions.

Fifo_map is a C++ header only library for associative container which uses the order in which keys were inserted to the container as ordering relation.

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.
