iiinova — where your digital self keeps evolving

I have forked and published sbt-revolver with experimental Scala Native support – running long-lived Scala Native processes in the background directly from your sbt build. Things like HTTP servers and UI (e.g. gtk) apps seem to work. Also ported sbt 2 support from upstream.

Recording of my talk from Scalar is up. In the talk, I invite you to a gentle waltz with a 50-year-old sabre-tooth behemoth called C and why Scala should care about learning to communicate with it.

I was able to browse the catalogue without signing up or anything: www.libraryofthings.co.uk/catalogue/br... And can indeed see a thermal camera available near me, which I didn't know about. This will make things interesting.

FWIW I get that in Safari, Chrome, and Firefox :)

I usually find overbaking more problematic for slow tasks. In Scala Native, I experimented with a custom merkle tree hashing of the config to provide detailed feedback about why exactly overbaking occurs: github.com/scala-native... Wonder if something like this (but more generic) can be in sbt 2?

Felt cute, thought I'd do some compile time numbers

Thought I'd see how sharp the bleeding edge is and converted my Scala Native CLI tool build from scala-cli to sbt2. And it works! Machine-wide caching works too, great for Github Actions

Finally got around to do a tool I desperately need – Scala Native-specific interactive binary size explorer. $ sn-sizer serve test-binary Starting server on localhost:52616

I'm a big fan of Decline, but I still think that leaving macro-derived CLIs off the table is incorrect – you can get quite far with enums, case classes, and annotations in small to medium apps. In my projects I use both the raw Decline API and my own derivation mechanism for it.

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...

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...

For something more relatable, here's a Scaladex MCP server: github.com/keynmol/scal.... Note that the model did not get any project descriptions and decided to just wing it.

Anton Sviridov @indoorvivants.com · 11/05/2025

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.

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.

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.

New blog post. Let's call Java/Scala JVM from Scala Native using JNI. Because why not. blog.indoorvivants.com/2025-02-08-j...

Don't just take my word for it – I added a HLJS comparison mode

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...

Demonstration of cue4s - cross-platform Scala 3 library for CLI prompts that works on JS, Native, and the JVM. This demonstration is performed by running the Scala.js version of the library in terminals emulated by Xterm.js

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/...

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
