@nixCraft hmm... does the example shows SwiftUI in use?

I do wonder when they would allow it for #Windows & #Linux -- could be interesting alternative to #Kotlin

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.
