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

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

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.

RTTR stands for Run Time Type Reflection. It describes the ability of a computer program to introspect and modify an object at runtime. It is also the name of the library itself, which is written in C++.

Taskflow is a C++ library for writing parallel and heterogeneous task programs.

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.

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.

LunaSVG is an SVG rendering library in C++, designed to be lightweight and portable, offering efficient rendering and manipulation of Scalable Vector Graphics (SVG) files.

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.

This package implements a generic template for extended width signed and unsigned integral types. Up to 63 limbs of any built-in integer type are supported, and can be used to build powers of two like int128_t, uint256_t, but also somewhat esoteric types such as int24_t, uint80_t, or uint1536_t. The provided types can be used in much the same way as basic integer types.

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

mcpp is Matsui's CPP implementation precisely conformed to standards.

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

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

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

This package provides a base64 stream encoder/decoder written in C99.

CodeSynthesis XSD (also known as libxsd or xsdcxx) is an XML Schema to C++ data binding compiler. Provided with an XML instance specification (XML Schema), it generates C++ classes that represent the given vocabulary as well as XML parsing and serialization code. The data stored in XML can then be accessed using types and functions that semantically correspond to an application domain rather than dealing with the intricacies of reading and writing XML.

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.

cli is a domain-specific language (DSL) for defining command line interfaces of C++ programs. It allows you to describe the options that your program supports, their types, default values, and documentation.

This package provides the official implementation for hypr configuration language used in Hyprland.

cpplint is a command-line tool to check C/C++ files for style issues following Google’s C++ style guide. While Google maintains its own version of the tool, this is a fork that aims to be more responsive and make cpplint usable in wider contexts.

This package provides a header-only implementation of std::variant (formerly boost::variant) for C++11/14.

tl::optional provides a single-header implementation of the std::optional for C++11/14/17, with support for monadic operations added in C++23.

This package provides a simple argument parser for C++.
