cmp-buffer VS cmp-nvim-lsp

sources = cmp.config.sources({ { name = "nvim_lsp", priority = 1, group_index = 1 }, { name = "luasnip" }, { group_index = 2, name = "buffer", priority = 5, option = { -- https://github.com/hrsh7th/cmp-buffer get_bufnrs = function() return vim.api.nvim_list_bufs() end, }, }, { name = "nvim_lsp_signature_help" }, { name = "path" }, }),

cmp-buffer: Completion source. It provides suggestions based on the current file.

Then what is the purpose of using cmp-buffer?

Okay I sat down and did exactly what I said in my previous comment. Essentially it's a complete rewrite of my old code that makes things much more generic and flexible. You can take a look at the PR here: https://github.com/hrsh7th/cmp-buffer/pull/60.

Good work but can you tell how is it different from https://github.com/hrsh7th/cmp-buffer

hrsh7th/cmp-buffer - nvim-cmp source for buffer words

cmp-buffer

nvim-cmp is just the autocompletion engine w/ fuzzy matching and other filtering options. To get items to be filled from cmp you will need sources, for example: hrsh7th/cmp-nvim-lsp plugin will provide items from a LSP server to cmp, so you can get items you can fuzzy match in. Another one is items from buffers: hrsh7th/cmp-buffer

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.
