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.

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 simple S-Expression parser for C++.

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

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

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

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

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

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.

This package provides a library that portably invokes native file open, folder select and file save dialogs. It allows the specification of a default file name and location, as well as filters with friendly names (such as "source files" or "image files") where supported.

Tweeny is an inbetweening library designed for the creation of complex animations for games and other beautiful interactive software. It leverages features of modern C++ to empower developers with an intuitive API for declaring tweenings of any type of value, as long as they support arithmetic operations. The goal of Tweeny is to provide means to create fluid interpolations when animating position, scale, rotation, frames or other values of screen objects, by setting their values as the tween starting point and then, after each tween step, plugging back the result.

lexy is a parser combinator library for C++17 and later.

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.

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

toml11 is a C++11 (or later) header-only toml parser/encoder depending only on C++ standard library.

• It is compatible to the latest version of TOML v1.0.0.

• It is one of the most TOML standard compliant libraries, tested with a language agnostic test suite for TOML parsers.

• It shows highly informative error messages.

• It has configurable container. You can use any random-access containers and key-value maps as backend containers.

• It optionally preserves comments without any overhead.

• It has configurable serializer that supports comments, inline tables, literal strings and multiline strings.

• It supports user-defined type conversion from/into toml values.

• It correctly handles UTF-8 sequences, with or without BOM.

The BDE Development Environment libraries provide an enhanced implementation of STL containers, vocabulary types for representing common concepts (like dates and times), and building blocks for developing multi-threaded applications and network applications.

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.Note: This package is a major update of the original clipper library.

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.

Xbyak is a C++ header-only JIT assembler for x86(IA-32), x64(AMD64/x86-64) architecture. It supports MASM/NASM-like syntax and advanced instruction sets including AVX-512, APX, and AVX10.2.

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.

This package provides a single-header implementation of C++20's std::span, conforming to the C++20 committee draft. It is compatible with C++11, but will use newer language features if they are available.

AsmJit is a lightweight library for machine code generation written in C++ language. It can generate machine code for X86 and X86_64 architectures with the support for the whole instruction set from legacy MMX to the newest AVX-512 and AMX. It has a type-safe API that allows C++ compiler to do semantic checks at compile-time even before the assembled code is generated or executed. It also provides an optional register allocator that makes it easy to generate complex code without a significant development effort.
