COLLADA-DOM is a C++ library for loading and saving COLLADA documents that can contain 2D, 3D, physics and other types of content.

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

reproc (Redirected Process) is a C/C++ library that simplifies starting, stopping and communicating with external programs. The main use case is executing command line applications directly from C or C++ code and retrieving their output.

ZenLib is a C++ utility library. It includes classes for handling strings, configuration, bit streams, threading, translation, and cross-platform operating system functions.

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.

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

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.

PlutoVG is a standalone 2D vector graphics library in C.

readerwriterqueue provides a lock free queue supporting a two-thread use case (one consuming, one producing). Features include:

• compatible with C++11 (supports moving objects instead of making copies)

• fully generic (templated container of any type); just like std::queue, you never need to allocate memory for elements yourself

• allocates memory up front, in contiguous blocks

• provides a try_enqueue method which is guaranteed never to allocate memory

• provides an enqueue method which can dynamically grow the size of the queue as needed

• Completely wait-free (no compare-and-swap loop). Enqueue and dequeue are always O(1) (not counting memory allocation)

• On x86, the memory barriers compile down to no-ops

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.

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.

This library allows the user to define a command-line interface from a program's help message rather than specifying it programmatically with command-line parsers like getopt and argparse.

JUCE is a C++ application framework for creating applications including VST, VST3, AU, AUv3, AAX and LV2 audio plug-ins and plug-in hosts.

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.

xtl is a C++ header-only template library providing basic tools (containers, algorithms) used by other QuantStack packages.

JNetLib is a portable C++ asynchronous network abstraction layer. It features:

• TCP connections support,

• listening sockets support,

• asynchronous DNS support,

• HTTP serving and getting support,

• Completely asynchronous love for single threaded apps.

This package provides the official implementation for hypr configuration language used in Hyprland.

Folly (acronymed loosely after Facebook Open Source Library) is a library of C++14 components that complements std and Boost.

SafeInt is a class library for C++ that manages integer overflows. It also includes a C library that checks casting, multiplication, division, addition and subtraction for all combinations of signed and unsigned 32-bit and 64-bit integers.

libxsd-frontend is a compiler frontend for the W3C XML Schema definition language. It includes a parser, semantic graph types and a traversal mechanism.

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

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

This package provides a header-only C++ library to parse command line options. It supports the short and long option formats of getopt(), getopt_long() and getopt_long_only().
