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.

Chimney 0.7.0 released
Hello, if you have some nice examples could you please check if it's something that would fit any of issues planned for 0.7.1 or create a new one?
-
Smithy4s 0.15.0, now with Smithy 2.0 support
Thankfully, there are some solutions that can help reduce the boilerplate of these manual conversions. For instance, chimney : https://scalalandio.github.io/chimney/

Is it possible to get runnable generated scala code from a macro (chminey to be specific)?
I want to upgrade one project to Scala 3.1, but I'm using the macro heavy chimney (https://github.com/scalalandio/chimney) to reduce the boilerplate, which is not available for Scala 3 yet. My idea was to copy and paste the code that chimney generates on 2.13, and after that uncomment the uses of chimney for now.

From ES6 to Scala: Basics
In my $dayjob we originally used Scala, but I pushed for a couple of new services to be written in TypeScript/Node as it was really hard to hire Scala developers. I'd say it worked well, we even took a somewhat functional approach to building things. We tried fp-ts but that was a bit hardcore (when you are trying to hire TypeScript developers who don't know functional programming), so just built Either and Option types which provided 99% of what we needed.
There are still a few things I miss though:
* Pattern matching and exhaustive checking. Using a switch statement it is possible to define a function that can emulate the compile-time exhaustive checking, but it's still rather weak compared to what you can do in Scala.
* Implicits. Being able to define something that can convert say a UUID to a String or vice versa automatically just feels like magic, especially when dealing with data from third party systems.
* Compiler macros and metaprogramming. It enables tools like Chimney (https://scalalandio.github.io/chimney/) to be built, which I don't think are possible with TypeScript right now.

Ideas for a Scala 3 MapStruct library?
Hi! Are you aware of https://github.com/scalalandio/chimney? I think that's what you are trying to do. Sorry if I misunderstand your message.

Simple, Naïve, and Wrong: More than you wanted to know about Scala Case Classes
And for exactly the same reasons one shouldn't override equals and hashCode in a case class, they shouldn't manually implement an enumeration and instead let a well-tested macro (2.x) or the compiler itself (3.x) handle reliably doing the automated code generation. The more code that is generated by the compiler, the smaller the defects, technical debt, and security vulnerability surface areas.

A survey of programming language enum support
For Scala, check out the enumeratum library (https://github.com/lloydmeta/enumeratum). In my opinion its the best enum implementation I know of. It has all the features defined in the table, and the syntax is really clean. It even supports unique associated values (eg. unique String/Int keys).
What are some alternatives?

Monocle - Optics library for Scala
