I've been using Parinfer with IntelliJ (Cursive) ever since I started developing Clojure professionally back in 2018. The best thing about Parinfer, or at least the implementation in Cursive, is that it doesn't preclude you from also mixing in some Paredit commands too.

When you start out with Clojure/Lisp and you aren't totally used to parenthesis you can just use Parinfer to get editor behaviour similar to developing Python. It removes a major pain point of migrating to a Lisp. It used to be the case that you were forced to learn Paredit pretty much from the start.

I've used it for a number of years, but I do believe that while this is really helpful, it's a little incomplete.

It has gaps around pasting content and how to handle that elegantly as well as comment behaviour, if those two things could be reconciled, it would be even more useful :)...

This is really nice, and I am impressed how much effort went into the documentation, to make the demo nice and interactive.

At first I thought this is something new, because it's cool and I haven't heard of it, even though I'm coding in Clojure for about 3 years now. But this project is already 10 years old and hasn't received much attention for the last few years, which is a pity. I wish it was coming with Calva, my favorite Clojure tooling in VS Code.

After using Parinfer for a few years the editing experience felt less like typing and more like a cross between magic and the scene from Ghost in the Shell with the split hands. It's a real shame they weren't able to add it to Calva.
