Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How do I remove the forward reference error in my parser? (20 lines)
Perhaps use Li Haoyi's fastparse instead? https://github.com/com-lihaoyi/fastparse

Parse slightly dirty, poorly escaped XML
You might want to adapt Li Haoyi’s XML parser for fastparse.

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.

Parser generators vs. handwritten parsers: surveying major languages in 2021
Agreed! I would say that parser combinators are the sweet spot and the right choice in most cases.
Scala has them as well, e.g.: https://com-lihaoyi.github.io/fastparse/
And the good thing is, you don't have to learn a completely new language/syntax, you can use the host language's syntax and you have full IDE support as well.
What are some alternatives?
Scallop - a simple Scala CLI parsing library
Parboiled2 - A macro-based PEG parser generator for Scala 2.10+
decline - A composable command-line parser for Scala.
Scala Parser Combinators - simple combinator-based parsing for Scala. formerly part of the Scala standard library, now a separate community-maintained module
Kaitai Struct - Kaitai Struct: declarative language to generate binary data parsers in C++ / C# / Go / Java / JavaScript / Lua / Nim / Perl / PHP / Python / Ruby
atto - friendly little parsers
