✨ Sometimes a bit of frustration leads to good questions. This talk looks at what Scala highlighting gets right, what it gets wrong, and why it still matters. Here’s "Tree Sitting will continue until Scala highlighting improves" by Anton Sviridov

New post! Self-contained multi-stage Dockerfiles are rad Post: blog.indoorvivants.com/2025-10-14-s... Repo: github.com/indoorvivant... I use this old approach a lot in my apps (fullstack mostly) and I'm confident it's good enough for most people.

To celebrate the release of Cats Effect for Native 0.5, I rebuilt my web interface for sn-bindgen in Smithy4s and Http4s. Now on Native 0.5, and actually working! Blog post: blog.indoorvivants.com/2025-09-22-s... App: sn-bindgen-web.indoorvivants.com Repo: github.com/indoorvivant...

Here's a live coding session I did for London Scala User Group about Scala Native and how it can interop with C, C++, and even Assembly. Super fun, by the end of it we had a blazing fast HTTP server built with a sprinkle of ARM64 assembly www.youtube.com/watch?v=rRPe...

We have two exciting live-coding talks for you this July! ☀️ Join us on Jul 23rd (Wed) 6pm to see some cutting edge Scala in action from Nicolas Rinaudo and Anton Svirdov! Sign up here: 👇 www.meetup.com/london-scala...

Thank you for attending yesterday's Scala Talks! Thank go to @thetradedesk.bsky.social for having us round for pizza, drinks and a beautiful view. Special thanks go to our fantastic speakers @indoorvivants.com and @noelwelsh.bsky.social . See you next time!

It was great fun to present at @londonscala.bsky.social , talking about modern CLI covenants as I see them, and using Scala Native to build a wonderfully personal snippet manager for myself Code: github.com/indoorvivant... Slides: slides.indoorvivants.com/clis-with-sc...

I had fun contributing the new SimpleTable class to the ScalaSql query library. It lets you drop the `T[_]` from table definitions, and it's based on named tuples and structural types in Scala 3.7. Have a read.

Got invited to Imperial College of London to do some livecoding for students, this time making a simple Electron app with Scala.js searching Scala libraries. github.com/keynmol/scal...

Hello folks 👋 ScalaIO is back for another edition in 2025 🥳 🌐 It will be held at La Grande Crypte, Paris 🇫🇷 on the 17/10/2025 🎟️ Early birds tickets are already open to sales(f: Person => `scala.io`) 🤝 CFP & sponsorships will open very shortly See you soon 😊

I've been playing around with MCP to understand the hype, and wrote a small library (codegen, really): github.com/indoorvivant... This image itself was generated by my CLI (Scala Native btw!) tools, into which I added a mcp subcommand.

🎉Workflows4s is finally out! A Scala library designed for simpler, type-safe, and lightweight workflows. medium.com/business4s-b...

Scala so dead it's not even on the list 😭

"Scala devs deserve the same productivity support as the rest of the JVM world. By joining the Scala Center Advisory Board, we’ll help identify pain points and bring better tools to the community." —Hans Dockter, Gradle CEO scala-lang.org/blog/gradle-...

Try it: keynmol.github.io/scalameta-as... Code: github.com/keynmol/scal... Built with Scala 3, Scala.js, and Laminar

With AST seemingly explorer not maintained, I decided to try and implement it in Scala.js. Lots of fun, until I hit several recursion bugs in my interval tree implementation, and it was hell from that point onwards. This will soon be hosted under Scalameta org and website.

🤝 Rock The JVM x Scala Center 🎓 @rockthejvm.bsky.social Scala courses are now officially recommended on Scala-lang! 🌟 PLUS, 30% of revenue from course purchases goes to the Scala Center to support the Scala community! www.scala-lang.org/blog/2025/02...

Released scala-uri 4.2.0, now with Scala Native 0.5 support: github.com/indoorvivant... The native part currently depends on libidn2, but I'm working on a pure Scala Punycode implementation, to remove dependency on scalajs-dom (and browser) in Scala.js as well.

Functional Programming in #Scala part 3 of 3 about to start (9am Pacific), you can watch on Twitch too: www.twitch.tv/softinio There will be mentions of #Monads and #Effect systems! #BayAreaScala #Meetup #Course #FunctionalProgramming cc @makingthematrix.github.io @scala.intellijidea.com

Two coding artists I most revere collide in an unexpected way.

Scala Days 2025 is heading to Lausanne, Switzerland! From August 19–21, the Scala community will gather at EPFL’s SwissTech Convention Center for top-tier talks, workshops, and networking with co-located events starting on August 18.(1/2)

Updated my little Raylib + Scala 3 Native experiment to use Raylib 5.5 and Scala Native 0.5. Still works! Had to update because of breaking changes in Raylib 5.5, bindings had to be rebuilt. Code: github.com/indoorvivant... Blog: blog.indoorvivants.com/2024-02-05-d...

Happy to announce that @jetbrains.com has joined us as a Golden Sponsor! Thanks for being a part of the #scalarconf adventure 🐟

📯 Scala 3.6 is out! 💪 Improved syntax for givens, context bounds (SIP-64) 💪 Multiple, interleaved type parameter lists (SIP-47) 🧪 Experimental features, such as named tuples 🎉 and more; details: scala-lang.org/news/3.6.2 ⚠️ use 3.6.2; ignore 3.6.1 and 3.6.0

Last night I added a bunch of improvements to my Tree Sitter powered Scala syntax highlighter. Themes, facelift, latest tree-sitter-scala (now with named tuples support!), and a bunch of build niceties. keynmol.github.io/scala-treesi... I plan to write a blogpost about how all of this works.

Here's an interactive cue4s demo running in the browser, using xterm.js and Scala.js! Have a go: keynmol.github.io/cue4s-xterm-... See how it's built: github.com/keynmol/cue4...

Cue4s 0.0.3 is out, and with this version I was able to port dexsearch to it, removing the javascript prompts dependency entirely! cue4s: github.com/neandertech/... dexsearch: github.com/neandertech/...

The thirstrap bot followers really make this new place feel like the old one

Quickest I ever deployed anything probably Mimalyzer: check if a change triggers a MiMa problem Try it: mimalyzer.fly.dev Code: github.com/keynmol/mima... Template: github.com/indoorvivant... It's built in like 40 minutes, so it will constantly crash, bye :P
