Spend almost the whole day working on #clojure contract project. It's a real pleasure to use cider with integrant for interacting with repl and reloading namespaces. The most satisfying tools I have ever used so far.

I also use eglot and few other #emacs packages, but cider is a piece of cake. I have been donating to it for a few years and would like to continue when I get some spare funds.
