Dotty highlighting for Scala sources?

[armanbilge]

Currently, Scala 3 "Dotty" highlighting is activated only if the sources are marked as dotty:

```dotty

In my case, the problem is that this doesn't work with mdoc:

```dotty mdoc

I'm not sure if there's any good way to resolve this, without sacrificing either Scala 2 or Scala 3 syntax highlighting.

Yes, there is no obvious default, as everyone would have different preferences. I kept the Scala 3 syntax separate for two reasons:

1. The nearly non-existent adoption of Scala 3

2. If they are initially separate, users can still re-configure them to get Scala 3 syntax for a scala code block, the other way round would not be possible. If they are pre-merged you could not "configure them apart".

If you want to switch today, you can do this:

laikaExtensions := Seq(SyntaxHighlighting.withSyntaxBinding("scala", DottySyntax))

Aha, I had a feeling there must be a config for this. Thanks as always!

[armanbilge]

Although, I think that as more projects cross-build for Scala 3 they will be avoiding the Scala 3 keywords. So not sure when, but at some point it's probably okay to flip the switch.

[jenshalm]

At some point, yes. How about "when Spark is on Scala 3" 🙂

If anyone else stumbles here, the method is actually called withSyntaxBinding :)

Btw, sbt-typelevel-site will apply the extension automatically if you are using Scala 3.
