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

This package provides a single-header C++11 library for computing Fast Fourier transformations. It supports multidimensional arrays, different floating point sizes and complex transformations.

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 library provides a header-only unordered set and map data structures for C++.

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 package provides a compatibility header-only library for C++17 string-view.

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.

Highway is a performance-portable, length-agnostic C++ library for SIMD (Single Instruction, Multiple Data) with runtime dispatch.

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.

IceCream-Cpp is a C++ library for printf debugging. It is inspired by the Python library of the same name.

This package provides header-only TOML config file parser and serializer for C++17.

RapidFuzz is a fast string matching library for Python and C++, which is using the string similarity calculations from FuzzyWuzzy.

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.

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

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

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.

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).

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

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

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.

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.
