iiinova — where your digital self keeps evolving

Having built developer tools for half my career (literally!), I decided to build something “useless” this time. Today I’m announcing RubyLens, a gem that turns your Ruby codebase into a galaxy, as either a page or a video! Here’s an example using Discourse：

Haven’t posted my workout for a while. Did 70kg and (maybe) 72.5kg weighted pullup yesterday 😙

The biggest visible change is type information next to method documentation. RBS signatures now show up in both HTML and `ri`, and Aliki presents method entries as signature cards.

RDoc 8.0.0 is out now. This is the biggest RDoc release in years, and it brings together a lot of the Ruby documentation work I talked about at RubyKaigi. Also, RDoc now has a logo!

In the next release, cctop will help you clean up stale worktrees from your finished sessions!

After weeks of work, Ruby’s master documentation now displays rbs signatures! We will release this feature in RDoc 8.0 soon as well. So any projects using rbs (inline or .rbs files) can benefit from it too. Check it on docs.ruby-lang.org/en/master

RDoc server mode with live reload is almost ready for ruby/ruby. Currently `make html` takes 30-60s and you have to rerun it after every change. With `make html-server`, you get instant live reload. (Just found a bug with page links, but it's getting there) Here is a demo:

Yesterday I released cctop v0.11.0 with a redesign and 4 color schemes! If you want a lightweight macos app to help you monitor Claude Code/opencode sessions with keyboard navigation, give cctop a try: github.com/st0012/cctop

RDoc has always supported Markdown as a markup language. But its support was buggy and lacks documentation. After a year of addressing various related issues, I was able to rewrite a doc for it. I think we'll soon be able to migrate from RDoc to Markdown. ruby.github.io/rdoc/doc/mar...

I'm very honored to have received this year's RubyPrize from Matz's hands in Matsue last Thursday, recognizing my work on Ruby and its development tools. I can still remember how nervous I was asking Matz for a picture back in 2016 😂 Time really flies (Photo from @hsbt.org ❤️)

Finally got a full #frontlever after entire year of training 😵 Skill difficulties from my experience: frontlever >> one arm pullup >>>>> muscle up

Never imagined I could do a 200% bodyweight pull-up (my weight + 60 kg plates) even in my early twenties—yet at 31, I got it today 😛

It’s been 6 years since my last visit, and @asakusarb still gave me the warmest welcome! Same good vibes, delicious food, and wonderful #rubyfriends. Grateful to be back in such a lovely community 🥰

Tomorrow I’m flying to Matsuyama for @rubykaigi with a 100-day 🇯🇵 streak on Duolingo. Still can’t hold a conversation, but hopefully I’ll understand signs and menus a bit better!

Spent my weekend improving the Ruby MCP prototype to allow: - Fuzzy searching classes - Query class details like ancestors, methods, definitions - Query method details like params, owner, and comments Will try to get it released as experimental feature before RubyKaigi 😁

PoC: A Ruby MCP server (powered by Ruby LSP) interacting with the Cursor agent. Ruby MCP can provide your project's: - Dependencies - Indexed classes/modules/methods - Runtime info (powered by a Rails add-on) - Anything else supported by other add-ons to the client. Thoughts?

Every week, I spend at least a few hours to make the RDoc codebase a little bit better.

Not that it changes anything, but I’m happy to have become the #1 contributor to IRB on all metrics (PRs, commits, lines added, and lines removed) 😄

Almost got this combo (almost because my front-lever dipped). It’d be amazing if I can get it before Ruby 3.4’s release at Christmas 😁

Do you use IRB's integration with debug.gem (irb:rdbg)? Reference: github.com/ruby/irb?tab... Can't do poll here yet, so let me know what you think about it by commenting below 👇

Let’s give Ruby’s English documentation new homepages! If this is accepted in time, it’ll be applied to the upcoming Ruby 3.4 documentation. We can then explore ways to backport similar changes to older Ruby versions. PR: github.com/ruby/ruby/pu...

A good language’s default tooling should cover most of its developers’ needs right out of the box 🙂

Earlier this week, RDoc and docs.ruby-lang.org received a great contribution from Alexis Bernard (@alexis_bernard on Twitter): An ancestors list in the class page's sidebar! Once we added a similar section for descendants, navigating between classes will be a much smoother experience.
