hi Denis,

Please advise on https://scalameta.org/paradise/ since it is not maintained anymore.

Any plans to move away from it?

[SemanticBeeng]

Trying to upgrade to scalameta 4.0.0 and getting some errors related to paradise.

Please advise if this attempt to upgrade conflicts with anything and what it would take.

UPDATE: scalafmt latest uses scalameta 4.0.0 and no paradise
https://github.com/scalameta/scalafmt/blob/175ee66e048e690aeb8a22f56ab4fd355c219ca8/project/Dependencies.scala#L9

This older fork uses scalameta 1.7.0 and paradise
https://github.com/olafurpg/scalafmt/blob/12ed28a683cd4b45335e48d9d31d789ae9ed2235/project/Dependencies.scala#L8

Point being: so should be a way to migrate from paradise.
Interest to discuss?

@SemanticBeeng unfortunately scalameta/paradise is EOL. Any suggestions regarding another implementations are highly appreciated.

[SemanticBeeng]

Yes, we need a way around/way from paradise.

See typelevel/cats-tagless#6 (comment) and another one below for some research and thinking. Do not miss scalameta/scalagen#22 about cats.

Thoughts?

Trying to use the same approach scalafmt has used to move away from it seems in reach from this high level but you would know better.

If you think is worth pursuing then let us do a code review for how you used it, please.

UPDATE: freestyle uses a similar approach to annotations and boiler plate code generation so they are stuck too with paradise.

Also, I'd like to use such generated code to compile with scalajs to call from Ajax client applications.

http://frees.io/docs/core/algebras/
"For each smart constructor def foo(x: X, y: Y, ...): FS[Z], the @free generates a case class Foo, whose fields are the parameters of the constructor. For those with a background in object-oriented design, this is similar to the Command Pattern."

Do you see any reason why such generated code would not be compiling with scalajs?
