What it is

Ruby is a programming language designed to be pleasant to read and write. Rails, or Ruby on Rails, is a web framework built on it: it gives a new web app a database layer, routing, templates and tests from the start, and favors sensible conventions over configuration. GitHub, Shopify and Basecamp were built with it.

Ruby libraries are called gems; Bundler installs the ones a project needs from its Gemfile.

Why it's here

• Fast to build web apps. rails new gives you a working app in minutes.
• Batteries included. Database migrations, background jobs, mail and tests are part of the framework.
• Ruby itself. A good language for scripts and automation, too.

On CoreDesktop

Ruby and Rails aren't installed for everyone. To add them, run configure languages and answer yes to Ruby on Rails. It installs the latest Ruby with mise (mise use -g ruby@latest), then the Bundler and Rails gems. Each new version of Ruby gets Rails and Bundler automatically, and update moves you to the newest Ruby and updates Rails and Bundler, leaving your other gems as they are.

Machines that had Ruby from an earlier CoreDesktop keep it, and update reinstalls Rails if an earlier move to a new Ruby lost it. If you don't use Ruby, remove it with mise unuse -g ruby.

Start a new app with:

rails new myapp
