The Fastest FizzBuzz in the West: Build Your Own Language with RPLY and RPython

In this talk, you'll learn how I built DIVSPL (Dustin Ingram's Very Special Programming Language), a tongue-in-cheek domain-specific language, which is particularly good for implementing FizzBuzz -- as quickly as possible.

We'll build DIVSPL with RPLY, an implementation of David Beazley's PLY (but with a "cooler" API) and make it compatible with RPython, a restricted subset of the Python programming language. Along the way, you'll learn about lexers, parsers, and grammars, and in the end, you'll know how to build your own programming language.

This talk is for anyone who has ever wondered how computers understand programming languages, or how to create your own programming language. It will be approachable for novices who have never studied programming language design, but will offer tools and concepts that will enable experienced users to actually build their own language, if they so desire.
