cmp-nvim-lsp VS lspkind.nvim

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.

There's a cmp-icons plugin: https://github.com/onsails/lspkind.nvim and also you can see the cmp documentation inside vim running :h cmp I spend many hours reading each plugin documentation to customize all my plugins. I hope I've helped.

If you are referring specifically to icons in your autocompletion suggestions menu you have to set it to use them. This can be achieved manually with the format key in the nvim-cmp setup (assuming you are using nvim-cmp) or with a plugin like lspkind.nvim

If you use neovim, you can refer to my init.lua; I use vim-go, lsp and other goodies like lspkind to display vscode-like pictograms.

(See [#30](https://github.com/onsails/lspkind-nvim/pull/30)) --before = function (entry, vim_item) --... --return vim_item --end }) }, completion = { autocomplete = true }, })

All the snippets, mapping, formatting and sources part in the above code snippet is expalained nicely in the plugin's documentation. For above code to work, you also have to install lspkind which provides awesome icons in the code completions.

To style the completion popup, you need to add formatting. Going by the cute little scissors, you probably want to install lsp-kind and add something like this to your cmp.setup

I copy pasted the icons from https://github.com/onsails/lspkind-nvim/blob/master/lua/lspkind/init.lua and added the spaces:
