  • Eval 0.1.0 released

    A more limited way to do runtime evaluation is via the jsr-223 support: https://github.com/lampepfl/dotty/blob/main/tests/run-with-compiler/scripting.scala, you can't reflect on types that way but the advantage is that you don't end up depending on compiler-internals APIs that could change in any patch release.

    https://github.com/lampepfl/dotty/issues/14262 points to https://github.com/invesdwin/invesdwin-context/blob/master/invesdwin-context-parent/invesdwin-context-scala/src/main/java/de/invesdwin/context/scala/pool/WrappedScalaScriptEngine.java which seems to be doing some caching via https://docs.oracle.com/javase/8/docs/api/javax/script/Compilable.html, but I have zero experience with this stuff.

    Note though that our jsr-223 support is currently a bit limited compared to the scala 2 version: https://github.com/lampepfl/dotty/issues/14262

    If you could open an issue at https://github.com/lampepfl/dotty/issues detailing your problems with the bash shell on Windows that would be useful (it's likely our scripts have only been tested with the cmd.exe shell).

    - If you can't generate a quotation and need any strings, then the next option - add compiler to the classpath and use JSR223 scripting API: (example : https://github.com/lampepfl/dotty/blob/master/tests/run-with-compiler/scripting.scala

    The main blocker for such libraries is https://github.com/lampepfl/dotty/issues/11685 now, that also blocks cats-tagless, and hopefully it will be fixed in near future. So if you can wait several months, it would be the easiest choice... so do I :)
  • GraalVM native-image with Scala 3 reflection hell
    3 projects | reddit.com/r/scala | 9 Jan 2022
    See https://github.com/lampepfl/dotty/issues/13985, maybe the graalvm reflection config format could be enriched to support wildcards if it doesn't already?
