How to embed Ammonite-REPL in Scala 3?

[vaclavsvejcar]

I used embedded Ammonite-REPL with Scala 2.x successfully, but after migrating to Scala 3 I'm having trouble to compile the code using the guide from documentation:

ThisBuild / scalaVersion := "3.1.1"
...
libraryDependencies += "com.lihaoyi" % "ammonite" % "2.5.2" cross CrossVersion.full

Then in code

ammonite.Main(predefCode = code).run("ast" -> ast, "defs" -> defs, "json" -> json)

and I'm getting compile error:

[error] 45 |      ammonite.Main(predefCode = code).run("ast" -> ast, "defs" -> defs, "json" -> json)
[error]    |                                           ^^^^^^^^^^^^
[error]    |                          Found:    (String, dev.svejcar.sjq.model.Node)
[error]    |                          Required: ammonite.util.Bind[?]

It looks that Scala 3 doesn't like either the implicit conversion in ammonite.util.Bind#ammoniteReplArrowBinder or how it uses the TypeTag stuff (which AFAIK is not in Scala 3).

My question is, is Ammonite-REPL supposed to work embedded from Scala 3 code and if yes, what should I do to make it work?

It's possible to work around the arrow binder issue but then we get stuck with "No TypeTag available for Int".

ammonite.Main().run(ammonite.util.Bind("myInt", 1234))

This is fixed in 3.0.0-M0-59-cdeaa580

Confirmed working in 3.0.0-M0-59-cdeaa580 and Scala 3.3.1.
