parinfer

[Suya1671]

when working with lisps, https://github.com/eraserhd/parinfer-rust is a great tool to make the experience much better. Maybe there could be a way to directly interface with parinfer-rust since its well, rust and has a lib.rs file. Although it doesn't seem to reexport many functions.

If it is decided that the plugin scripting language will be some variant of lisp, native integration with parinfer would be nice to have. Otherwise a plugin would be the appropriate path. Either way a plugin system will have to be put in place first.

Adding to this conversation in the event the plugin system does end up being a lisp variant.

Another option to consider when implementing s-expression structural editing might be something similar to guns/vim-sexp but with bindings similar to those provided by tpope/vim-sexp-mappings-for-regular-people as they potentially align better with the Helix defaults.

Another potential project to take inspiration from is abo-abo/lispy which is an Emacs plugin that uses vim-like key bindings.
