Not sure what you mean. The Scala example looks nothing like the Clojure examples.

The retention charts show you how much new code is replacing old code, and you can see the releases/rewrites as the code gets replaced.

The charts are very cool. But they’d be more informative if they tracked _interface_ changes. Maybe Scala is more flexible and the code changes are limited to optimizing the underlying implementation while keeping stable interfaces. It’s impossible to tell from the charts.

I really liked those charts, I wonder how you can generate them, whether there's a tool out there that you can just feed a Git repo into or something.

pip install git-of-theseus git clone repo cd repo git-of-theseus-analyze . git-of-theseus-stack-plot cohorts.json

Thank you! This was super useful!
