Writing your tests in EDN files
https://biffweb.com/p/edn-tests/
I've previously written about my latest approach to unit tests: [Y]ou define only the input data for your function, and then the expected return value is generated by calling your function. The expected value is saved to an EDN file and checked...
Today the #clojure jet CLI tool to transform between JSON, EDN and Transit is 6 years old!
What would you name a #Clojure library for handling terminal/console codes? A library not as fancy as Lanterna, but in the same family.
Scaffolding, #clojure, 2025.
Datastar has a Clojure SDK and it now works with (the latest) bb: https://github.com/starfederation/datastar-clojure
An exciting new blog post about how to build a simple web "app" using Babashka and CGI.

You've heard of #scala language that works on the jvm. You also heard about scala native target to native (C) and interoping with that world side stepping the #jvm...
Now get ready for #clojure (jvm language) and it's target to Cpp.

#jank programming language - Clojure/LLVM/C++
"Where jank differs from Clojure JVM is that its host is C++ on top of an LLVM-based JIT*
The lovely thing about Clojure (or any LISP for that matter) is that you start with
step 1: learning its data structures,
then you proceed to
step 2: learning the syntax, which you've already done in step 1
I'm revived and alive! Feeling a THOUSAND times better. I've been reading my #tolkien fairy tale book with my #cat. Gotta have that kitty energy. Sometimes I read outloud to him, and he just lays there, being my pillow, flicking his tail and listening to the story :) Now I think I'm going to do some #code in #clojure. I'll be on #SDF listening to #anonradio :D
The Architecture Behind Ooloi: A Quarter-Century in the Making

Now that the backend engine is complete, architecturally speaking, I'm getting increasingly eager to open the source. Itching, in fact. But as that will take a while, the least I can do for you is give you the WELCOME.md file from the source...

Finally got over the hump and was able to re-build my Babashka-based project into a binary with GraalVM. It really does start so much faster that way.
The hump I couldn't get over is tools.build. This is the fourth time I've tried to use it for a project. Even after trying neil and uberdeps and I can't remember what else ... it just wouldn't build an uberjar.
After hours of trying, I switched over to Leiningen and had the uberjar and compiled binary in about 20 minutes.
My project updates for May and June:

A very well-written article that deserves another share: Understanding Polylith through the lens of Hexagonal architecture https://medium.com/@joakimtengstrand/understanding-polylith-through-the-lens-of-hexagonal-architecture-8e7c8757dab1
Since the article was written, the Python tooling for Polylith has support for "all" Package & Dependency management tools out there such as uv, hatch, pixi and not only Poetry.
@shriramk Yeah.. #JaneStreet is the #OCaml company, and #Nubank is the #Clojure company. I need to takeover some FinTech and make it the #Racket company, though that might lead to some awkward audit questions ("What's this Racket you're involved in?") .
FWIW, #upvest is very much a #go company, and for good reasons. ;-)
Introducing python-tap - a tiny Python library useful for REPL Driven Development
Useful when running code on your local machine. With this tool, you can store and process data, such as function input parameters or local variables. This is useful when inspecting code and flows, and when running code in a REPL. You will have all the tapped data available in the session.
Yes, it is inspired by "tap>" in Clojure!
@jackdaniel @NGIZero h'mmm ... Yesterday, not for the first time, I was looking at reimplementing #InterLisp's GRAPHER library in #Clojure. It's doable, but surprisingly difficult. If there was a good Java SVG engine which allowed callbacks through JavaScript or whatever, it would be easier, and *possibly* Batik may do that.
But #CommonLisp in the browser, interacting with SVG in the browser... Now that sounds fun.
