languageserver VS cmp-nvim-lsp

I'm not familiar with data science, but I would start with setting up a language server for R: https://github.com/REditorSupport/languageserver . Kate already have a default client configuration for it, so it should work out of the box.

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.

Installed languageserver in R.

Lsp server for R like py-right for python. Check this

I have downloaded the language server from here https://github.com/REditorSupport/languageserver, but don't know where it put it. so form now it's in the "R\R-4.1.3\bin".

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).

You need to add nvim-cmp and cmp-nvim-lsp

I had the exact problem recently with svelte and Astro. I opened an issue that never got any reply.: https://github.com/hrsh7th/cmp-nvim-lsp/issues/56

Plugins Needed: * nvim-lspconfig * nvim-cmp * cmp-nvim-lsp

-- need to install https://github.com/hrsh7th/cmp-nvim-lsp for server in pairs(servers) do lspconfig[server].setup { on_attach = on_attach, capabilities = require("cmp_nvim_lsp").default_capabilities(), settings = servers[server], } end ```

cmp-nvim-lsp: Completion source. Shows data send by the language server.

The default capabilities are from this plugin: https://github.com/hrsh7th/cmp-nvim-lsp

cmp-nvim-lsp: integração com LSP;

nvim-lspconfig is only for configuring the language-servers. You need to add the https://github.com/hrsh7th/cmp-nvim-lsp source to nvim-cmp in order to get lsp completions

Peeking at the code, it is explicitly called out in the function update_capabilities here

Yep. Make sure you have cmp-nvim-lsp installed, as well as an LSP server running.
