Facebook has released a new library, written in the C programming language that is a layout engine for GUI applications. It is called Yoga and it is aimed at web developers who have used the CSS flex box layout styles. It is possible to use the library with Java, C#, and Objective-C and can be used with React Native.
It handles laying out widgets in grid patterns or other layout styles using flex box styles like flex direction and flex wrap and alignment.
It is possible to integrate Yoga into an existing layout engine.
It’s an open question as to where this fits in if you’re using GTK or Qt to develop a desktop or mobile application.
