Those are use cases that we explicitly did not want to support since they cause language fragmentation, with many possible dialects supported by macros. I am sure there are good use cases for this, but overall I believe allowing this would be detrimental to the language ecosystem as a whole.

Scala 2 macro type class derivation for `Coder[P <: Product]` ends with error `P does not take parameters`

Asked 2021-May-07 at 13:54

I am a starter with Scala 2 Macros (before I switch to Dotty) who after trying out the shapeless type class derivation wanted to go one step beyond and write a macro that can generate a type class instances for any scala.Product without it.

(for the sake of example let's ignore nested recursive types, so my goal is flat case classes.)

My type class is an abstract class Coder[T] (e.g. trait with encode() / decode()).

So the generated code for:

How to setup different Scala versions on the same machine?

Asked 2021-May-04 at 22:22

I want to follow the book on Scala[1] but it uses Scala 3 and I have Scala 2 installed. I want to use both the versions, something on the lines of python2 and python3.

I tried installing Scala3 on my local using the official source but I could only grasp the project-level working directory. The sbt prompt does not work like a REPL would and I can only open REPL using Scala 2 (I checked the version everytime).

How do I open the REPL of Scala3 given I cannot uninstall Scala2?

...

ANSWER

Answered 2021-May-04 at 22:22

The sbt prompt does not work like a REPL

If you execute sbt console from within project directory it will drop you into REPL version corresponding to the project's scalaVersion. For example, executing sbt console within project created with sbt new lampepfl/dotty.g8 would start Scala 3 REPL.

but I could only grasp the project-level working directory

For system-wide installation first install coursier and then execute cs install scala3-repl. This will install Scala 3 REPL alongside the Scala 2 one. Now Scala 3 REPL can be started with scala3-repl command whilst Scala 2 REPL simply with scala command.

QUESTION

How do existential types overlap with path-dependent types?

Asked 2021-Apr-18 at 14:36

Starting Scala 3 existential types have been dropped and one of the reasons is stated as

Existential types largely overlap with path-dependent types, so the gain of having them is relatively minor.

Given "largely", so not always, I was wondering if a concrete example can be provided demonstrating how to rewrite an existential type as path-dependent type, and an example when such replacement is not possible?
