Implementing Ranges and Views

Wednesday, September 18 • 16:45 - 17:45 MDT

by Roi Barkan

Summary of the talk:

Since `ranges` were introduced to C++20, a new paradigm was presented to us C++ developers. This paradigm, [sequence oriented programming](https://cppcast.com/sequence_oriented_programming/) allows easy expression of useful algorithms, helps us decompose problems into smaller-clearer sub-problems and has the potential of increasing the readability and maintainability of solutions we develop to difficult problems.

Though rich and diverse, the set of tools in our `ranges` toolbox is at its infancy, and the robust design of the library makes it possible for us to extend it with algorithms and views on our own. Doing so can increase our productivity, enrich our vocabulary and also be fun and challenging.

In this talk I'll discuss the structure of the ranges library in terms of its main `concept`s and how it was designed to be extensible (especially as on C++23).

We will focus on the implementation `range views`, and go over several examples of how new views which aren't part of the standard should be designed and implemented, in a way that fits with the rest of the `ranges` library.

Join me in the development of range adapters as we learn about range categories, concepts, adapters, customization-point-objects and range-adapter-closures.
