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.

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++.

libxsd-frontend is a compiler frontend for the W3C XML Schema definition language. It includes a parser, semantic graph types and a traversal mechanism.

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.

cpp-httplib is a C++11 single-file cross platform blocking HTTP/HTTPS library, easy to setup. It can also be used as a single-header library.

This package provides simple string utilities for C++.

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

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.

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 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.

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

SWELL is a Windows emulation Layer. It provides a set of common APIs, common controls and win32-style extensions.

std::expected is proposed as the preferred way to represent objects which will either have an expected value, or an unexpected value giving information about why something failed. Unfortunately, chaining together many computations which may fail can be verbose, as error-checking code will be mixed in with the actual programming logic. This implementation provides a number of utilities to make coding with expected cleaner.

This package provides a Python library named _jsonnet which can evaluate Jsonnet files and expressions.

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 is a simple C++ library that facilitates parsing command line arguments in a type independent manner.

CLI11 is a command line parser for C++11 and beyond that provides a rich feature set with a simple and intuitive interface.

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.

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.

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.

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.

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

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