That sounds very useful and it's not something that vim gives you out of the box but I'm not sure that anything you're describing is not possible via LSP plugins and extensions.

Running a server to automatically search for duplicate code sounds exactly like the kind of task that LSP can handle.

Since VSCode has tools for deep flow analysis (although I can't say how they compare to Intellij) then I'm pretty sure I can access them from neovim.

Maybe if I was a Java developer something like Intellij would look more attractive but I've never really been impressed with the rest of the JetBrains IDE family.

Horses for courses I guess. If there's some tool you want that's only available in Intellij then that's what you'll use.

All of that is of course theoretically possible with LSP or other vim extensions. It's just that nobody did it.

Another thing is the level of integration. There are many tools which offer static analysis, duplicate detection etc. But it's completely different level of usability when you see this info immediately as you type.

People already use LSP in vim/neovim. Realtime feedback as you type is a thing in vim.

Here is an example for typescript users.

Again this does require you to configure things and that may not be what you want to spend your time doing but it's perfectly possible.

Also I'll add that I'm not arguing that vim is better than any other particular IDE or editor, just that IDE like features can easily be added.

Yeah, I know that you can use LSP in vim. But LSP for most languages is a far cry from what you can get in "real" IDEs.

It's always "LSP could be just as good" or "support for that can be easily added" - but it's just not happening - nobody does the work to make that just as good.
