The AWS SDK for C++ provides a C++11 interface to the AWS API. AWS provides on-demand computing infrastructure and software services including database, analytic, and machine learning technologies.

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.

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

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

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

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.

This package provides a C++ implementation of several hash map and a hash set variants using open addressing and hopscotch hashing to resolve collisions. It is intended to be fast and provides additional features, such as heterogeneous lookups and different growth policies.

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

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

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.

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.

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.

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

This package provides simple property input/output utilities for C++.

This package provides the cmake imports needed to build bloomberg-bde.

This package provides a C++ implementation of a hash map and a hash set which preserve the order of insertion. It is intended for efficient ordered insertions and lookup, while sacrifing performance for ordered erase operations.

Range-v3 is an extension of the Standard Template Library that makes its iterators and algorithms more powerful by making them composable. Unlike other range-like solutions which, seek to do away with iterators, in range-v3 ranges are an abstraction layer on top of iterators.

CastXML is a C-family abstract syntax tree XML output tool. This project is maintained by Kitware in support of ITK, the Insight Segmentation and Registration Toolkit.

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.

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.

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.

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.

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.

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.
