Miniaudio is an audio playback and capture library for C and C++. It is made up of a single source file and has no external dependencies.

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

ChaiScript is one of the only embedded scripting language designed from the ground up to directly target C++ and take advantage of modern C++ development techniques. Being a native C++ application, it has some advantages over existing embedded scripting languages:

1. Uses a header-only approach, which makes it easy to integrate with existing projects.

2. Maintains type safety between your C++ application and the user scripts.

3. Supports a variety of C++ techniques including callbacks, overloaded functions, class methods, and stl containers.

scn is a text parsing library for C++. It can be used as a safe alternative to scanf or as a fast alternative to IOStreams, analogous to fmt.

This package provides a collection of C++ libraries intended to be useful for building network-based applications.

CastXML is a C-family abstract syntax tree XML output tool. This project is maintained by Kitware in support of ITK, the Insight Segmentation and Registration Toolkit.

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.

ccls is a server implementing the Language Server Protocol (LSP) for C, C++ and Objective-C languages. It uses clang to perform static code analysis and supports cross references, hierarchies, completion and syntax highlighting. ccls is derived from cquery which is not maintained anymore.

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

Immer is a library of persistent and immutable data structures written in C++.

libcutl is a C++ utility library. It contains a collection of generic and independent components such as meta-programming tests, smart pointers, containers, compiler building blocks, etc.

Hyprgraphics is a small C++ library with graphics/resource related utilities used across the hypr* ecosystem.

The C++ Actor Framework (CAF) offers a high-level C++17 programming environment using the actor model for concurrent, distributed computation.

tinyformat is a type-safe printf replacement library in a single C++ header file. Design goals include:

• Type-safety and extensibility for user defined types

• C99 printf compatibility, to the extent possible using std::ostream

• POSIX extension for positional arguments

• Simplicity and minimalism; a single header file to include and distribute with your projects

• Augment rather than replace the standard stream formatting mechanism

• C++98 support, with optional C++11 niceties

json_dto library is a small header-only helper for converting data between JSON representation and C++ structs. DTO stands for data transfer object.

libconfini is an INI file parser library written in C. It focuses on standardization and parsing exactness and is at ease with almost every type of file containing key/value pairs.

This package provides a header-only library to retrieve the file names of XDG base directories, such as XDG_CONFIG_HOME.

SysCmdLine is a C++ command line parser that is inspired by QCommandLineParser from Qt and System.CommandLine from C#. It has features such as:

• Support sub-commands

• Support case-insensitive parsing

• Support global options

• Support mutually exclusive options

• Support short options and group flags

• Support help text customization

• Support localization

• Simple tips for typo correction

• Highly configurable

• Friendly interface

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.

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

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.

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++.

FunctionalPlus is a header-only library for simplifying functional programming in C++.

The Permuted Congruential Generator (PCG) extends the Linear Congruential Generator (LCG) with a permutation function to increase output randomness while retaining speed, simplicity, and conciseness.
