The Unofficial 37signals/DHH Rails Style Guide

About This Document

This style guide was generated by Claude Code through deep analysis of the Fizzy codebase - 37signals' open-source project management tool.

Why Fizzy matters: While 37signals has long advocated for "vanilla Rails" and opinionated software design, their production codebases (Basecamp, HEY, etc.) have historically been closed source. Fizzy changes that. For the first time, developers can study a real 37signals/DHH-style Rails application - not just blog posts and conference talks, but actual production code with all its patterns, trade-offs, and deliberate omissions.

# config/initializers/route_format.rb
#
# Global route formatting override for Rails routing.
#
# This hooks into ActionDispatch::Routing::Mapper::Mapping and mutates the
# Journey AST in place so that underscored literal path segments are
# dasherized. It affects *all* routes (get, resources, scope, etc.)
# because they all end up as a Journey AST passed into Mapping.

Namespaces 101

Introduction

Ruby has recently merged namespaces as an experimental feature that is disabled by default, as of this writing.

This is a non-trivial development driven by @matz himself, and mainly implemented by @tagomoris, who just became a Ruby committer (🎉).

The feature has been cooking for a long time, with a first ticket opened a couple of years ago (#19744) and a revised one opened just last week (#21311).
