@drewverlee that’s a good question
tianshu’s plugin is the most active: https://github.com/DogLooksGood/parinfer-mode and I believe it’s the only one porting over the new v3 stuff
spacemacs has parinfer in its dev branch, and it uses tianshu’s plugin (parinfer v1 i believe): https://github.com/syl20bnr/spacemacs/tree/develop/layers/%2Bmisc/parinfer
