The zed editor is a modern and very snappy editor developped in rust. It’s a bit behind more mature emacs/vim/vscode in term of features, though it’s already pretty usable. There is an ocaml extension which I contributed to a little bit.
I’d be curious to know if other people have tried this editor and would be willing to put a little bit of work into the extension. For now I do it mostly for myself. And would probably have more motivation if I knew it’s actually being used by other people too.
