nvim VS nvim-lspconfig

I've found an example config with vim-mucomplete. Most configs I've found for R seem to use ncm-R, ncm2 and nvim-yarp but I could not make those work at all on my system.

cd ~/.local/share/nvim git init . git submodule init mkdir site/pack/plugins/opt/ git submodule add --depth 1 https://github.com/neovim/nvim-lspconfig site/pack/plugins/opt/nvim-lspconfig

The LSP server is configured by nvim-lspconfig, which is hidden behind lsp-zero.

As for your specific situation, it might be that you're talking about lsp-zero or, more specifically, Mason. Mason is basically a package manager for language servers and it uses npm under the hood. However, if you don't want that kind of bloat on your system, you can do perfectly fine without Mason. In that case, you only install nvim-lspconfig as I describe here, and instead of using Mason to install language servers, you install them manually (system-wide, probably) and point your lspconfig to them. For me, Mason is a nice enough convenience to justify the baggage, but you can easily live without it.

nvim-lspconfig

I like to describe lsp-zero as an opinionated configuration wrapped in a plugin. It was made to reduce the boilerplate code necessary to configure nvim-cmp and nvim-lspconfig.

Working on it ;) https://github.com/neovim/nvim-lspconfig/pull/2381

https://github.com/neovim/nvim-lspconfig: when you know project structure and just need go to definition.

As mentioned by others, there are now some tools that now help alleviate those problems (like https://github.com/VonHeikemen/lsp-zero.nvim) , however I still think debugging and DAP is painful for new users. Something like LspConfig for DAP or a similar simplified experience might help.

You need to set up lsp. It provides all the functions. Check out :h lsp, lspconfig, lsp-zero
