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.

Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional

Example

Desfazendo um git push

Não é possível desfazer um push diretamente, como é feito com o commit utilizando o comando $ git reset --soft|mixed|hard hash-do-penultimo-commit

Para desfazer um push são necessários 3 passos:

Utilizar o comando $ git reset --mixed HEAD~1 e em seguida utilizar o comando $ git stash (se preferir pode usar a opção -m "revertendo o push blablabla" para salvar o stash com um contexto do que foi feito
Utilizar o comando $ git revert HEAD~0
Utilizar o comando $ git stash apply
Utilizar o comando $ git push origin sua-branch -f

This list is based on aliases_spec.rb.
