Description:
Following my previous talk ( • Anthony Cros - Gallia:... ) at Scala Days last year, two major pieces of feedback emerged for Gallia (github.com/galliaproject/gall... one was the need for performance improvements (for another talk) and the other was migration to Scala 3. The strong demand for the latter surprised me as I did not expect the community to have adopted it so quickly, and so successfully. I therefore decided to tackle the migration first, albeit not without some hesitation and some serious apprehension.
In this talk I will highlight my journey tackling this endeavor in concrete terms (where does one start?), lessons I've learned for other projects that will also need migration, and the positive/negative aspects of the overall process. As the title of the presentation suggests, I would rate my overall experience as quite positive. This was unexpected because while Scala 3 looked great on paper, this kind of migration can be an extremely frustrating experience irrespective of the context.
I will briefly introduce how certain features worked before (e.g. the now defunct `scala.reflect.{api,runtime}`) prior to showing the new approach(s), as well as why I chose to handle certain problems the way I did, notably when it came to reflection and macros.
