Done with the (ugly) spike, now reimplementing my #Kotlin #SymbolProcessing project, with a more sensible design, and with more Tests and TDD (*).

It's great fun when one already knows what works and what does not, and design is the main challenge, not the functionality (not anymore).

(*) I'm still finding it hard to test some parts of the symbol processor, since it runs in the compiler. But that's not a big problem for me right now.

Yesterday, I started to play with #Kotlin symbol processing again, after I didn't manage to create something working ~2 years ago.

This time, I managed to create a proof-of-concept of something I wanted to work on for a long time!

Pretty messy code right now, will clean it up a bit and add more tests, then I'll push it to Codeberg.

New blog post: What's in a parameter name?

Frameworks like Spring MVC and Embabel often rely on method parameter names as a way to implement Convention over Configuration. But in Java and Kotlin, those names are not always available.

I explain the details in this post: https://poutsma-principles.com/blog/2025/09/25/parameter-names/

I created a toy #Java project using #JSpecify

This is what you can express (among others):

https://codeberg.org/michael-simons/javaspektrum/src/commit/14281628ac054dfcaed2c4e3bf951f3329da6b49/jspecify/src/main/java/ac/simons/javaspektrum/jspecify/Calculator.java#L9

One required argument, one optional argument with optional content.

To check it, you need to have #Nullaway https://codeberg.org/michael-simons/javaspektrum/src/commit/14281628ac054dfcaed2c4e3bf951f3329da6b49/jspecify/pom.xml#L319-L341

Build with mvn package -DwithNullaway, to see compile fail (there's test passing null).

Nullaway and modern Java is fun: https://codeberg.org/michael-simons/javaspektrum/src/commit/14281628ac054dfcaed2c4e3bf951f3329da6b49/jspecify/.mvn/jvm.config#L5-L12

Also added #Kotlin code: You can remove the package, and see how it affects what Kotlin sees.
