So what is it?

This is the source repository for the book "Game Programming Patterns" by Bob Nystrom. The book covers design patterns, software architecture, and optimization techniques specifically in the context of writing games. It is available to read for free on the web and was also published in print. The repository contains the full text of the book written in Markdown files, a Python script that converts those Markdown files into HTML, a SASS stylesheet, and an HTML template. If you want to build the book locally, you install a few Python packages and run the format script, which processes all the chapters and produces the finished HTML files in an output directory. The script can also run in watch mode and automatically rebuild whenever you make changes to the source files. The author notes in the README that the book is finished and he is no longer actively working on this repository. He is not responding to issues or pull requests, but he does read everything filed and says a second edition is a possibility at some point in the future. He asks that people continue to report bugs even though responses should not be expected. The book itself is aimed at programmers who are writing games and want to learn how to structure their code better. The topics include well-known software design patterns adapted to the specific needs of game development, along with patterns specific to games that are less discussed in general programming literature. The repository has no license information in the README, and the README is brief given that the primary deliverable is the book rather than the tooling.
