Hi I am currently working on a new validation library yet an kotlinlang #server

Hi! I am currently working on a new validation library (yet another) and I want to be sure it fits your expectations. I've created a short survey (5 questions only) to gather facts about validation usage inside Kotlin's ecosystem. I would be really grateful if you could take a few minutes of your time to answer and help me with this project. 🙏 https://forms.gle/wfX9cte8GYhpiQTp6

My hopes/requirements: • No ksp or other compiler hacks. I need less of that in my life not more. • Declarative syntax ala konform is great. we're using that. • Multi-platform is important to us. We put our datamodels in a multi platform library that is used on the web (kotlin-js) and in our spring boot server. We are considering using wasm and compose multiplatform as well. Anything with jvm dependencies is not usable for us.

Thank you to all of you 🙂

@Jilles van Gurp Unfortunately, my library currently involves a small annotation processor, which is required to make the syntax way more readable. However, we could imagine a way for the user to disable the processor and fall back on an API a bit more verbose. Currently, if you have the following models:

Copy code

data class Book(val author: Author)
data class Author(val name: String)

With the KSP processor you can do:

Copy code

Validator<Book> {
    author.name.length {
        between(2, 50)
    }
}

Without it we could imagine a fallback on a Konform-ish syntax:

Copy code

Validator<Book> {
    Book::author + Author::name + String::length {
        between(2, 50)
    }
}
