Rapid YAML
Library to parse and emit YAML, and do it fast
Or ryml, for short. ryml is a C++ library to parse and emit YAML, and do it fast, on everything from x64 to bare-metal chips without operating system. (If you are looking to use your programs with a YAML tree as a configuration tree with override facilities, take a look at c4conf). ryml parses both read-only and in-situ source buffers; the resulting data nodes hold only views to sub-ranges of the source buffer. No string copies or duplications are done, and no virtual functions are used. The data tree is a flat index-based structure stored in a single array. Serialization happens only at your direct request, after parsing / before emitting. Internally, the data tree representation stores only string views and has no knowledge of types, but of course, every node can have a YAML type tag. ryml makes it easy and fast to read and modify the data tree. -

Cutelyst
Web Framework built on top of Qt, using the approach of Catalyst
Create fast and modern web applications that share the same code as your desktop or mobile apps. Why have two or more development teams focused on a specific platform when you can have a single team coding the same code, sharing skills and lines of code. With Qt, you already can write applications for Windows, Linux, Android, MacOS, and iOS using the same source code, Cutelyst allows you to share your C++ code with your web application. Cutelyst has a WSGI server that supports HTTP/1.1, HTTP/2, FastCGI, and WebSockets, it can even be embedded in your application if you like. It also features a plugin for uWSGI which gives us support for HTTP/1.0, FastCGI, and uWSGI protocols but is slower and doesn't support WebSockets. Running standalone or behind a web server is really easy. With your application logic written in C++ your application get's really small, a full CMS (like this one) uses around 5MB of RAM which can be shared with other instances of the same application. -

Nano JSON
Lightweight, facility, high performance golang based game server
Nano is an easy-to-use, fast, lightweight game server networking library for Go. It provides a core network architecture and a series of tools and libraries that can help developers eliminate boring duplicate work for common underlying logic. The goal of nano is to improve development efficiency by eliminating the need to spend time on repetitious network-related programming. Nano was designed for server-side applications like real-time games, social games, mobile games, etc of all sizes. In fact, the nano application is a collection of Components, and a component is a bundle of handlers, once you register a component to nano, nano will register all methods that can be converted to Handler to nano service container. -

Spots
Spots is a cross-platform view controller framework
Spots is a cross-platform view controller framework for building component-based UIs. The internal architecture is built using generic view models that can be transformed both to and from JSON. So, moving your UI declaration to a backend is as easy as pie. Data source and delegate setup is handled by Spots, so there is no need for you to do that manually. The public API is jam-packed with convenience methods for performing mutation, it is as easy as working with a regular collection type. At the top level of Spots, you have the SpotsController which is the replacement for your view controller. -

QBooru
Simple viewer app for most Booru Sites, coded in Qt C++
QBooru is a lightweight Windows and Linux client that allows users to see pictures from most booru sites, and download them, for example : - Gelbooru - Danbooru - Konachan - Yandere - Safebooru - Rule34 At the moment, it supports 4 APIs : - Gelbooru - Danbooru 2 - Moebooru - Derpibooru Searchs are done by the JSON APIs. Thumbnails are cached locally, and are re-used by the program if needed. Interface The current interface allows users to chose how many pictures they want, within 3-5 rows and 5-8 columns. The recommended size is 3*5, as it fits perfectly the smallest window size. Search tab example : http://puu.sh/cK0pj.jpg Users can change nearly all the parameters through the Option tab, or by editing the configuration.json file. Boorus can be added, edited, and deleted through the Booru tab in the software, but they can also be edited manually in the configuration file. -
