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.

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.

debug_assert is a C++11 header-only library which provides the DEBUG_ASSERT() macro, which among other features can be selectively enabled in different parts of your code.

ArgAgg is yet another C++ command line argument/option parser. It was written as a simple and idiomatic alternative to other frameworks like getopt, Boost program options, TCLAP, and others. The goal is to achieve the majority of argument parsing needs in a simple manner with an easy to use API.

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

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

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

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.

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

c2ffi is a tool for extracting definitions from C, C++, and Objective C headers for use with foreign function call interfaces. It uses the Clang/LLVM infrastructure to extract the data, and emits it in various formats, including json.

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.

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.

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.

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.

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.

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.

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).

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

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.

frozen is a header-only library that provides zero cost initialization for immutable containers, fixed-size containers, and various algorithms. It provides features such as:

• immutable (also known as frozen), constexpr-compatible versions of std::set, std::unordered_set, std::map and std::unordered_map

• fixed-capacity, constinit-compatible versions of std::map and std::unordered_map with immutable, compile-time selected keys mapped to mutable values.

• zero cost initialization version of std::search for frozen needles using Boyer-Moore or Knuth-Morris-Pratt algorithms.

The unordered_* containers are guaranteed perfect (no hash collision) and the extra storage is linear with respect to the number of keys.

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

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.

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.

fast_float is a header-only C++ library for parsing floating point numbers from strings. It implements the C++ from_chars functions for the float and double types.
