Hi, AFAIK, neovim is trying to offload some of it's stuff (autocomplete/linting) to a language server via LSP. They're also offloading syntax highlighting to tree-sitter.
But I highly doubt that this is what you're looking for when you're talking about a "unix-like" editor. The dependancy on tree-sitter is specficially what made me uninstall neovim and switch over to vanilla vim. - NRK
