This MVC (Model-View-Controller) architecture for Jupyter interactive widgets allowed us to reuse all of the frontend implementation, by simply providing an alternative backend in C++, implementing the same messaging protocol. The MVC (Model View Controller) architecture of Jupyter widgets, and synchronization with the backend Views of that widget model are instantiated upon display. The state of the object in the backend is synchronized with the state of the JavaScript frontend object. Jupyter widgets are special objects that trigger the creation of a counterpart JavaScript model object in the Jupyter frontend upon creation. Interactive C++ for Data Science (LLVM blog), by Vassil Vassilev, David Lange, Simeon Ehrig, and Sylvain Corlay - Interpreted C++ for GIS with Jupyter (Jupyter blog), by Martin Renou Using the RAII pattern for a widget library Interactive workflows for C++ with Jupyter (Jupyter blog), by Sylvain Corlay, Loic Gouarin, Johan Mabille, and Wolf Vollprecht. a plea for allowing the overloading of the dot operator in C++, to enable better proxy types.įor readers interested in knowing more about interpreted C++, we recommend the following posts:.an original implementation of the observer pattern, xproperty,.

an original application of CRTP ( Curiously Recurring Template Pattern),.discussions on value semantics and RAII ( Resource Acquisition Is Initialization),.In this article, we dive into some of the C++ techniques used in the implementation of the xwidgets library, including Simple interactive widgets at play in JupyterLab with the xeus-cling C++ kernel
