@doglooksgood Is this version over parinfer open source yet? I'd like to get some of my colleagues to test it 🙂

@dominicm yes, it's open source， on branch smart of parinfer-mode. But I don't think it's the time to deploy to melpa. I need more test on it

file parinfer-smart.el

@dominicm btw, if you have to have a try, remember to byte-compile this file, after byte-compile, it will cost 3080ms to process 2900 loc, otherwise, it will cost 140200ms on my MBP. the old version of parinfer-mode will cost about 1000ms.

I create a repo for trying new parinfer-mode. https://github.com/DogLooksGood/parinfer-mode-demo

@shaunlebron have you given any more thought to https://github.com/shaunlebron/parinfer/issues/92 ?

Oh, I see there's a pr
