Best way to port a scala + swing app to flutter?
Scala used to include a parser combinator library. I don't know whether it comes with a Scala grammar as an example but I'd probably take a day and experiment whether it would be possible to create an AST parser for the Scala grammar.

Mostly a mess of pattern matching. I really need to make some generic tree utilities. Haven't been able to find a decent parser combinator that works in Scala 3 (I usually use fastparse which depends heavily on Scala 2 macros, and scala-parser-combinators works in Scala 3, but I've had a lot of trouble getting it to not be too greedy), so I used the state monad from cats to parse at the bottom of the file, which I think turned out fairly nice.
What are some alternatives?
