What's New in Ruby 3.2's IRB? — Still a fundamental part of Ruby, the IRB ‘Interactive Ruby’ prompt now lives in its own repo and has its own release schedule. Nonetheless, v1.6 will be Ruby 3.2’s included version and has a variety of enhancements to keep an eye on.

Read This Post 'Unless' You're Not A Ruby Developer — Does the double negative in the title mean we should or shouldn't read it? This is exactly the kind of confusion this post is criticizing, suggesting that the unless keyword be tossed away. Ouch. Controversial.

  • As much as Shopify loves and supports Ruby, they're embracing Rust too, taking on Rust as their official systems programming language, and joining the Rust Foundation. They talk about the contrast between Ruby and Rust in the post too.

  • A 🐦 very neat example of some Ruby 3.2-flavored code from Victor Shepelev. Equally readable and modern.

  • First Ruby Friend is a worthwhile program to pair up experienced Rubyist mentors and new Rubyists.

  • Kevin Newton's fascinating Advent of YARV series has continued with a look at the internals behind global variables, constants and class and instance variables.

👾  Building Games with DragonRuby — The DragonRuby Game Toolkit is a Ruby implementation/framework for building 2D games and other graphical experiences.

Elixir-Style Pipelines in 9 Lines of Ruby — This is definitely a refined (ed: groan..) approach to pipelines, also using currying to give a nice syntax but a potential debugging headache.

How to Use Alpine.js with Rails and Turbo — We liked Simon’s own description: “For apps not needing Stimulus.js and just using Turbo, the Alpine.js framework offers the right amount of JavaScript to make your apps sparkle.” This is a nice introduction, and Alpine.js is a neat library providing quite a light attribute-driven touch to interactivity.

Smashing: A Sinatra Based Framework for Dashboards — Billed as the ‘spiritual successor’ to Dashing, a Shopify project, Smashing is designed for creating dashboards that look good on big screens (such as a TV in your office). A Ruby DSL is used to fetch data from various sources, and you get a drag and drop interface for laying out the dashboard.
