Jsonnet is a templating language extending JSON syntax with variables, conditions, functions and more.

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 header-only single-file std::filesystem compatible helper library, based on the C++17 and C++20 specs, but implemented for C++11, C++14, C++17 or C++20.

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

This package provides useful C++ classes and routines such as argument parser, IO and conversion utilities.

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

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.

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

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

Ada is a fast and spec-compliant URL parser written in C++. Specification for URL parser can be found from the WHATWG website.

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

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.

Rang is a minimal, header only C++ library for terminal goodies.

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 header-only TOML config file parser and serializer for C++17.

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

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

The C++ Actor Framework (CAF) offers a high-level C++17 programming environment using the actor model for concurrent, distributed computation.

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.

Dashel is a data stream helper encapsulation C++ library. It provides a unified access to TCP/UDP sockets, serial ports, console, and files streams. It also allows a server application to wait for any activity on any combination of these streams.

This package provides a fast multi-producer, multi-consumer lock-free concurrent queue for C++11.

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 lightweight library for calculating the edit distance between two sequences and finding an optimal alignment path for transforming one sequence into another.

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