    Android Runtime for NativeScript

    Android Runtime for NativeScript

    NativeScript for Android using v8

    Contains the source code for the NativeScript's Android Runtime. NativeScript is a framework that enables developers to write truly native mobile applications for Android and iOS using JavaScript and CSS. Each mobile platform has its own ecosystem and offers completely different development tools and language(s) - Java for Android and Objective C (Swift) for iOS. In order to translate JavaScript code to the corresponding native APIs some kind of proxy mechanism is needed. This is exactly what the "Runtime" parts of NativeScript are responsible for. The Android Runtime may be thought of as "The Bridge" between the JavaScript and Android worlds. A NativeScript application for Android is a standard native package (apk) that besides the JavaScript files embeds the runtime as well.

    Catch2

    Catch2

    A modern, C++-native, test framework for unit-tests, TDD and BDD

    A modern, C++-native, test framework for unit-tests, TDD and BDD - using C++14, C++17 and later (C++11 support is in v2.x branch, and C++03 on the Catch1.x branch). Catch2 is mainly a unit testing framework for C++, but it also provides basic micro-benchmarking features and simple BDD macros. Catch2's main advantage is that using it is both simple and natural. Test names do not have to be valid identifiers, assertions look like normal C++ boolean expressions, and sections provide a nice and local way to share set-up and tear-down code in tests. You are on the devel branch, where the v3 version is being developed. v3 brings a bunch of significant changes, the big one being that Catch2 is no longer a single-header library. Catch2 now behaves as a normal library, with multiple headers and separately compiled implementation.

    An efficient, small mobile key-value storage framework

    MMKV for Android is an efficient, small mobile key-value storage framework developed by WeChat. Works on Android, iOS, macOS, Windows, and POSIX. Efficient. MMKV uses mmap to keep memory synced with file, and protobuf to encode/decode values, making the most of Android to achieve best performance. MMKV supports concurrent read-read and read-write access between processes. Easy-to-use. You can use MMKV as you go. All changes are saved immediately, no sync, no apply calls needed. MMKV contains process locks, encode/decode helpers and mmap logics and nothing more. It's really tidy. MMKV adds about 50K per architecture on App size, and much less when zipped (apk). MMKV is published under the BSD 3-Clause license. Starting from v1.2.8, MMKV has been migrated to Maven Central. Older versions (<= v1.2.7) are still available on JCenter.

    doctest

    doctest

    Fastest feature-rich C++11/14/17/20 single-header testing framework

    doctest is a new C++ testing framework but is by far the fastest both in compile times (by orders of magnitude) and runtime compared to other feature-rich alternatives. It brings the ability of compiled languages such as D / Rust / Nim to have tests written directly in the production code thanks to a fast, transparent and flexible test runner with a clean interface. The framework is and will stay free but needs your support to sustain its development. There are lots of new features and maintenance to do. There are many C++ testing frameworks - Catch, Boost.Test, UnitTest++, cpputest, googletest and others. The key differences between it and other testing frameworks are that it is light and unintrusive. Ultra light on compile times both in terms of including the header and writing thousands of asserts. Doesn't produce any warnings even on the most aggressive warning levels for MSVC/GCC/Clang.

    openFrameworks

    Cross platform toolkit for creative coding in C++

    openFrameworks is a C++ toolkit for creative coding. docs have some documentation around OF usage, per platform things to consider, etc. You should definitely take a look in there; for example, if you are on OSX, read the osx.md. apps and examples are where projects go -- examples contain a variety of tasks that show you how to use OF, and apps is where your own projects will go. libs contain the libraries that OF uses, including the open frameworks core itself. addons are for additional functionality that's not part of the core. export is for DLLs and dylibs that need to be put in each compiled project. The scripts folder has templates and small scripts for automating OF per platform. project generator is a GUI-based tool for doing new projects - this folder is only there in packaged releases.

    Final Cut

    Final Cut

    A text-based widget toolkit

    Library for creating terminal applications with text-based widgets. FINAL CUT is a C++ class library and widget toolkit with full mouse support for creating a text-based user interface. The library supports the programmer to develop an application for the text console. It allows the simultaneous handling of multiple text windows on the screen. The structure of the Qt framework was originally the inspiration for the C++ class design of FINAL CUT. It provides common controls like dialog boxes, push buttons, check boxes, radio buttons, input lines, list boxes, status bars and so on. FINAL CUT uses a virtual terminal to print character via an update method on the screen. It provides (as an overlying layer) virtual windows for the realization of window movements. The update methods only transfer differences to the virtual terminal or physical screen.

    Neutralinojs

    Neutralinojs

    Portable and lightweight cross-platform desktop application

    Neutralinojs is a lightweight and portable desktop application development framework. It lets you develop lightweight cross-platform desktop applications using JavaScript, HTML and CSS. You can extend Neutralinojs with any programming language (via extensions IPC) and use Neutralinojs as a part of any source file (via child processes IPC). In Electron and NWjs, you have to install Node.js and hundreds of dependency libraries. Embedded Chromium and Node.js make simple apps bloaty, in most scenarios, framework weights more than your app source. Neutralinojs offers a lightweight and portable SDK which is an alternative for Electron and NW.js. Neutralinojs doesn't bundle Chromium and uses the existing web browser library in the operating system (Eg: gtk-webkit2 on Linux). Neutralinojs implements a secure WebSocket connection for native operations and embeds a static web server to serve the web content. Also, it offers a built-in JavaScript client library for developers.

    Python bindings for the Chromium Embedded Framework (CEF). CEF Python is an open source project founded by Czarek Tomczak in 2012 to provide Python bindings for the Chromium Embedded Framework (CEF). The Chromium project focuses mainly on Google Chrome application development while CEF focuses on facilitating embedded browser use cases in third-party applications. Lots of applications use CEF control, there are more than 100 million CEF instances installed around the world. There are numerous use cases for CEF. Use it as a modern HTML5 based rendering engine that can act as a replacement for classic desktop GUI frameworks. Think of it as Electron for Python. Embed a web browser widget in a classic Qt / GTK / wxPython desktop application. Use it for automated testing of web applications with more advanced capabilities than Selenium web browser automation due to CEF low level programming APIs.

    Easy-to-use deep learning framework with 3 key features

    MegEngine is a fast, scalable and easy-to-use deep learning framework with 3 key features. You can represent quantization/dynamic shape/image pre-processing and even derivation in one model. After training, just put everything into your model and inference it on any platform at ease. Speed and precision problems won't bother you anymore due to the same core inside. In training, GPU memory usage could go down to one-third at the cost of only one additional line, which enables the DTR algorithm. Gain the lowest memory usage when inferencing a model by leveraging our unique pushdown memory planner. NOTE: MegEngine now supports Python installation on Linux-64bit/Windows-64bit/MacOS(CPU-Only)-10.14+/Android 7+(CPU-Only) platforms with Python from 3.5 to 3.8. On Windows 10 you can either install the Linux distribution through Windows Subsystem for Linux (WSL) or install the Windows distribution directly. Many other platforms are supported for inference.
