Best resource to learn Scalia 3 metaprogramming

• ducktape

  5 393 9.3 Scala

  Automatic and customizable compile time transformations between similar case classes and sealed traits/enums, essentially a thing that glues your code. Scala 3 only. Or is it duct 🤔

I’m looking for small Scala 3 exclusive (mixing it with 2 makes much harder to distinguish) projects with use of metaprogramming where I can learn more and perhaps contribute. Ducktape (https://github.com/arainko/ducktape) is a great example. Any blog posts would be even better.

• dotty

  71 5,669 10.0 Scala

  The Scala 3 compiler, also known as Dotty.

  

Then start playing with reflection API - I suggest having Quotes opened in your IDE, and documentation in your browser. Use showRaw to print expressions you constructed - it will help you understand how to build from ground up when you cannot build something using only expressions.

  Quill for Scala 3

  

Among Scala 3-only macro codebases is proto-quill (Quill for Scala 3). Other than that most libraries will be cross-compiled Scala 2 and Scala 3 because they have to cater to both long-time Scala 2 users as well as those who already migrated.
