languageserver VS nvim-lspconfig

Symbol outline by LSP Client: It can connect to any LSP "server" (runs locally) which implements LSP protocol (https://microsoft.github.io/language-server-protocol/), and supports "stdin" communication. A number of LSP server configuration is provided by default (including R), but user can extend, and override this configuration. As long as the LSP servers are properly installed (kate will start them) and the Kate LSP client configuration is set up properly should work. LSP also provides other IDE-like features (like code completion, jump to symbol definition, diagnostic/linter messages) etc. I found an LSP server for R (https://github.com/REditorSupport/languageserver), you may want to give it a shot.

You'd need: - hrsh7th/nvim-cmp with set up LSP source (hrsh7th/cmp-nvim-lsp). - neovim/nvim-lspconfig. - R language server installed. This is a regular R package, can be installed from CRAN.

Besides a common modern Neovim "IDE setup", some other useful R-specific tools: - languageserver R package for LSP integration. - styler R package for code formatting. Somewhat slow and lacks some features, but seems to be the best current solution.

First of all, make sure that you actually use r_language_server. For that, at least install languageserver R package (run R from command line and execute install.packages("languageserver")) and set up r_language_server with nvim-lspconfig. I think after that you should be able to see some diagnostic information.

The truth is that most editors will use R language server underneath ( https://github.com/REditorSupport/languageserver ) so it's more what layout you prefer than what functionalities an editor has to offer.

Other plugins/utilities can fill in some of the other gaps. In the screenshot below, I'm using NvimTree to browse files, and I'm also currently using Neovim's native LSP client (in Neovim 0.5.0) with r_language_server installed (configured with the Neovim team's plugin nvim-lspconfig).

Figuring out what should be added is... an art (e.g. mason expects "bash-language-server", treesitter "bash", lspconfig "bashls"). The official docs with the official naming can be helpful here (nvim-lspconfig , treesitter , mason )

-- install plugins local plugins = { "https://github.com/rebelot/kanagawa.nvim", -- add any other plugins here { "https://github.com/neovim/nvim-lspconfig", config = function() require("lspconfig").tsserver.setup({}) end, }, } require("lazy").setup(plugins, { root = root .. "/plugins", })

you can use nvim-lspcofig for LSP support, mason.nvim for installing LSP servers, linters, formatters and debug adapters. nvim-cmp for completions, luasnip for snippets, null-ls for configuring your formatter and linters , lsp-inlayhints for inlay hints.

neovim/nvim-lspconfig is used for LSP configuration. In particular, lsp-zero.nvim is not needed. But in the configuration, the keybindings from both packages are linked and listed.

And just to clarify (not sure if this information is useful to you), lsp-zero only adds to the LSP server settings for the "capabilities" property and an on_attach function. Anything else is provided by nvim-lspconfig or mason-lspconfig.

Hello! I recently started using nvim after using vim on and off for some time. I've been using LazyVim since it seemed to have a good baseline configuration for me. I mostly develop in Java so I wanted to get additional features by using nvim-jdtls instead of the bundled nvim-lspconfig.

For those who don't know, lsp-zero is a plugin that bundles a configuration for nvim-lspconfig and nvim-cmp. The original idea was to make a setup for the built-in LSP client that didn't require too much effort.

To be fair nvim-lspconfig does make it easy to "connect" a language server with Neovim. That's all you need (and the language server itself, of course). People really struggle with the autocompletion part. Trying to replicate the exact behaviour of other editors is not that easy.

The coolest thing I've done is now I can code scheme lisp with help from my own LSP server named named scheme-langserver. With nvim-lspconfig and many other plugins, developing is really friendly. And many convenient fucntionalities such as autocompletion, goto definition are really helped and will help other lisp coder. Now, I hope my work will make NeoVim the better lisp editor than Emacs Lol.
