• CPU checker.

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

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

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.

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.

This package provides a single-header C++14 library for saving and loading C++ objects using a binary format.

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

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

A fast & densely stored hashmap and hashset based on robin-hood backward shift deletion for C++17 and later.

The classes ankerl::unordered_dense::map and ankerl::unordered_dense::set are (almost) drop-in replacements of std::unordered_map and std::unordered_set. While they don't have as strong iterator / reference stability guarantees, they are typically much faster. Additionally, there are ankerl::unordered_dense::segmented_map and ankerl::unordered_dense::segmented_set with lower peak memory usage, and stable references (iterators are NOT stable) on insert.

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

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)

sajson is an in-place JSON parser with support for parsing with only a single memory allocation.

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

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).

Async++ is a concurrency framework for C++11.

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.

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.

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

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

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

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

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

A lightweight header-only C++ option parser library, supporting the standard GNU style syntax for options.
