Anyone have an example for removal of Java like comments

You could try Scalaparse as a starting point: https://www.lihaoyi.com/fastparse/#ScalaParse

@cbley I tried Fastparse but because I am using Scala 3 (no Scala 2 macros), it was not possible.

Here’s the relevant part of the grammar handling comments: https://github.com/lihaoyi/fastparse/blob/master/scalaparse/src/scalaparse/syntax/Literals.scala#L49-L56

I am aware of the literals (found a reference to thees in a Gitter). I tried something similar here:

see [SOLVED] Parser combinator: removing comments

@cbley

Besides, what is this for? A one time job? You could also use cpp / gcc to remove Java style comments from your source files. (e.g. cpp -P -fpreprocessed your-file.scala > output.scala )

Not a one-time job. Preprocessing text before parsing in Scala.

@cbley

And maybe you should say what you mean with “text”?!

I need to strip illegal comments from a JSON file.

I think my problem is knowing how to combine the literals. My example above fails with:

    val text1 =
      """
        |text1//comment1
        |text2
        |//comment2""".stripMargin
