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.

SafeInt is a class library for C++ that manages integer overflows. It also includes a C library that checks casting, multiplication, division, addition and subtraction for all combinations of signed and unsigned 32-bit and 64-bit integers.

Those tools are meant to be used by solver developers to e.g. load MFront behaviours from external shared libraries and retrieve all relevant meta data function.

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

This library provides a header-only unordered set and map data structures for C++.

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

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

cpp-mustache is a Mustache implementation for C++ 11 and above. It is header only and has zero dependencies. It provides a templated string type for compatibility with any STL-like string (std::string, std::wstring, etc).

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.

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.

expected lite is a single-file header-only library for objects that either represent a valid value or an error that can be passed by value. It is intended for use with C++11 and later. The library is based on the std::expected proposal (http://wg21.link/p0323).

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

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

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

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.

Async++ is a concurrency framework for C++11.

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 C++ implementation of a hash map and a hash set with open addressing and sparse quadratic probing. It is intended to be memory efficient and provides additional features, such as heterogeneous lookups and different growth policies.

The Permuted Congruential Generator (PCG) extends the Linear Congruential Generator (LCG) with a permutation function to increase output randomness while retaining speed, simplicity, and conciseness.

This package provides a simple S-Expression parser for C++.

scn is a text parsing library for C++. It can be used as a safe alternative to scanf or as a fast alternative to IOStreams, analogous to fmt.

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.

KokkosKernels implements local computational kernels for linear algebra and graph operations, using the Kokkos shared-memory parallel programming model. "Local" means not using MPI, or running within a single MPI process without knowing about MPI.
