    Windows Package Manager (WinGet)

    Windows Package Manager (WinGet)

    WinGet is the Windows Package Manager

    A package manager is designed to help you save time and frustration. Essentially, it is a set of software tools that help you automate the process of getting software on your machine. You specify which apps you want installed, and it does the work of finding the latest version (or the exact one you specified) and installing it on your machine. The client is distributed within the App Installer package. While this package is pre-installed on Windows, the client will not be made generally available during the Preview period. In order to get automatic updates from the Microsoft Store that contain the client, one must install a Windows 10 Insider build and join the Preview flight ring by signing up. Installer behavior can be different depending on whether you are running winget with administrator privileges. You can also build the client yourself.

    Vcpkg

    Vcpkg

    C++ Library Manager for Windows, Linux, and MacOS

    Vcpkg helps you manage C and C++ libraries on Windows, Linux and MacOS. This tool and ecosystem are constantly evolving, and we always appreciate contributions! After you've gotten vcpkg installed and working, you may wish to add tab completion to your shell. With CMake, you will still need to find_package and the like to use the libraries. Check out the CMake section for more information, including on using CMake with an IDE. In classic mode, vcpkg produces an "installed" tree, whose contents are changed by explicit calls to vcpkg install or vcpkg remove. The installed tree is intended for consumption by any number of projects: for example, installing a bunch of libraries and then using those libraries from Visual Studio, without additional configuration. Because the installed tree is not associated with an individual project, it's similar to tools like brew or apt, except that the installed tree is vcpkg-installation-local, rather than global to a system or user.

    half

    C++ library for half precision floating point arithmetics.

    This is a C++ header-only library to provide an IEEE-754 conformant half-precision floating point type along with corresponding arithmetic operators, type conversions and common mathematical functions. It aims for both efficiency and ease of use, trying to accurately mimic the behaviour of the builtin floating point types at the best performance possible. It automatically uses and provides C++11 features when possible, but stays completely C++98-compatible when neccessary.

    Luau

    Luau

    Fast, small, safe, gradually typed embeddable scripting language

    It is designed to be backward compatible with Lua 5.1, as well as incorporating some features from future Lua releases, but also expands the feature set (most notably with type annotations). Luau is largely implemented from scratch, with the language runtime being a very heavily modified version of Lua 5.1 runtime, with a completely rewritten interpreter and other performance innovations. The runtime mostly preserves Lua 5.1 API, so existing bindings should be more or less compatible with a few caveats. Luau is used by Roblox game developers to write game code, as well as by Roblox engineers to implement large parts of the user-facing application code as well as portions of the editor (Roblox Studio) as plugins. Roblox chose to open-source Luau to foster collaboration within the Roblox community as well as to allow other companies and communities to benefit from the ongoing language and runtime innovation. As a consequence, Luau is now also used by games like Alan Wake 2 and Warframe.

    DirectX-Graphics-Samples

    DirectX-Graphics-Samples

    Samples that demonstrate how to build graphics intensive applications

    This repo contains the DirectX 12 Graphics samples that demonstrate how to build graphics-intensive applications for Windows 10. In the Samples directory, you will find samples that attempt to break off specific features and specific usage scenarios into bite-sized chunks. For example, the ExecuteIndirect sample will show you just enough about execute indirect to get started with that feature without diving too deep into multiengine whereas the nBodyGravity sample will delve into multiengine without touching on the execute indirect feature etc. By doing this, we hope to make it easier to get started with DirectX 12. D3D12 Mesh Shaders sample demonstrates how Mesh shaders can be used to increase the flexibility and performance of the geometry pipeline. D3D12 Variable Rate Shading sample demonstrates how shading rate can be reduced with little or no reduction in visual quality, leading to “free” performance.

    cpp-httplib

    cpp-httplib

    A C++ header-only HTTP/HTTPS server and client library

    A C++11 single-file header-only cross-platform HTTP/HTTPS library. It's extremely easy to setup. Just include the httplib.h file in your code! This is a multi-threaded 'blocking' HTTP library. If you are looking for a 'non-blocking' library, this is not the one that you want. SSL support is available with CPPHTTPLIB_OPENSSL_SUPPORT. libssl and libcrypto should be linked. When using SSL, it seems impossible to avoid SIGPIPE in all cases, since on some operating systems, SIGPIPE can only be suppressed on a per-message basis, but there is no way to make the OpenSSL library do so for its internal communications. If your program needs to avoid being terminated on SIGPIPE, the only fully general way might be to set up a signal handler for SIGPIPE to handle or ignore it yourself. cpp-httplib officially supports only the latest Visual Studio. It might work with former versions of Visual Studio, but I can no longer verify it.

    This repository contains several Arduino libraries I have written to be used in applications. Most of them include example code on how the libraries can be used. Furthermore, this repository contains a few stand-alone applications. For bugs in the libraries, please fill in an issue in Github as that makes it far easier to track them. If possible provide a minimal code snippet that exposes the bug. Add information about the platform used and version etc. Also, proposals for solutions are welcome. For improvements and changes, please provide a pull request. I will try to follow up on them asap but it can take quite some time. Please try to be generic in your improvements and try to see "over the needs of your own application".

    WOFF2

    WOFF2

    This document documents how to run the compression reference code

    woff2 is Google’s reference implementation of the WOFF2 webfont format, the modern, highly compressed container used by browsers to ship OpenType/TrueType fonts efficiently over the network. It integrates specialized transforms for font tables (like glyf/loca and variations data) with Brotli compression to squeeze out as many bytes as possible while preserving exact font fidelity on decode. The repository includes a compact C/C++ library and small command-line tools so you can convert existing TTF/OTF files to WOFF2 and back for testing or build pipelines. Its encoder applies deterministic, spec-compliant transformations that maximize compressibility without altering rendering results, making it safe for production web delivery. The decoder is just as strict, validating headers and table checksums to guard against malformed inputs. Because WOFF2 is now ubiquitous across browsers and CDNs, this repo often serves as the canonical baseline for tooling.

    ArduinoJson

    ArduinoJson

    JSON library for Arduino and embedded C++. Simple and efficient

    ArduinoJson is a C++ JSON library for Arduino and IoT (Internet Of Things). ArduinoJson has a simple and intuitive syntax to handle objects and arrays. ArduinoJson supports both JSON serialization and deserialization. ArduinoJson uses a fixed memory allocation, allowing to work on devices with very little RAM. ArduinoJson can filter large inputs to keep only fields that are relevant to your application, thereby saving a lot of memory. ArduinoJson can parse directly from an input Stream or std::istream. ArduinoJson can produce compact or prettified documents. ArduinoJson works directly with strings stored in program memory. ArduinoJson supports two coding styles, with implicit or explicit casts. ArduinoJson deduplicates strings in the JSON document. When you have several identical keys or values, the JsonDocument only stores one of each. In practice, this feature reduces memory consumption by 20-30%.

    JsonCpp

    JsonCpp

    A C++ library for interacting with JSON

    JSON is a lightweight data-interchange format. It can represent numbers, strings, ordered sequences of values, and collections of name/value pairs. JsonCpp is a C++ library that allows manipulating JSON values, including serialization and deserialization to and from strings. It can also preserve existing comment in unserialization/serialization steps, making it a convenient format to store user input files. The branch 00.11.zis a new branch, its major version number 00 is to show that it is different from 0.y.z and 1.y.z, the main purpose of this branch is to make a balance between the other two branches. Thus, users can use some new features in this new branch that introduced in 1.y.z, but can hardly applied into 0.y.z. You can download and install JsonCpp using the vcpkg dependency manager. The JsonCpp port in vcpkg is kept up to date by Microsoft team members and community contributors.
