nvim-parinfer is a Neovim plugin that uses Chris Oakman's parinfer-lua to implement the parinfer algorithm. Parinfer automatically balances parentheses as you type when working in Lisp-family languages. Unlike parinfer-rust, it requires no external dependencies: simply install and go.

nvim-parinfer uses sane defaults that should "just work". You can see the (small) list of configuration knobs in :help parinfer.
