Software Design by Example in Roc

Software Design by Example in Roc

The best way to learn design in any field is to study examples. These lessons therefore build scale models of tools that programmers use every day to show how experienced software designers think. Along the way, they introduce some fundamental concepts about pure functional languages that most programmers have never encountered. SDXRoc is a sequel to previous books in JavaScript and Python.

FAQ

• Why Roc rather than a more established language like Haskell, Clojure, or Elixir? One of the lessons from the previous books is that a large language can make design harder to see: core ideas might actually have been clearer if those books had used a smaller language like Lua. This book is also partly an experiment: can a project like this early in a language's development accelerate its evolution by drawing attention to oversights and sources of friction while the language is still malleable?

• What license are we using? The code is covered by the MIT License, so it can be copied, remixed, extended, and incorporated into other projects (both open and closed source). The prose (i.e., the text of the lessons) is covered by the CC-BY-NC-ND License, which means it is free to read but people must cite us as the source if they quote or copy it, cannot republish it commercially without our permission, and cannot create derivative works (e.g., translations) without our permission. We may remove some of these restrictions once we have a contract with a publisher, but they are in place now because it's much easier to relax a license after the fact than to tighten one up.

• How do I propose a topic? Create an issue with "topic proposal:" in its title and a brief description of what you'd like to cover. Greg will triage issues, start discussions, and identify overlaps.

• How do I know what topics are taken? Look at the "Topics" section of this file or for issues marked assigned in our repository.

• What if I don't have an idea but still want to contribute? Issues labeled help wanted in our repo are topic proposals in search of authors. If you are interested in taking one of these on, please add a comment to the issue and mention @gvwilson to start discussion.

• Where should code and notes go? For now, each topic should go in a subdirectory of the root directory whose name is a short hyphenated slug, e.g., editor or http-server. Each topic should be a standalone project; please include an index.md Markdown file with point-form notes about the design of the code.
