One of the coolest features that can make you more productive with NeoVim is autocompletion, so we have some plugins to choose between them based on the performance
- YouCompleteMe
- Coc.nvim
these plugins are great to use but they are very heavy because of Javascript and Python, so I decided to switch to another solution
and the solution is Lua Plugin called nvim-cmp
with this plugin you can add an auto-completion to your neovim with minimal performance, all you have to do is download the language server
Install
before installing the plugins you need to install Lua first
$ sudo pacman -S lua and you need a Plugin manager you can choose between
- vim-plug ( I use this )
- Pathogen
- Vundle
after installing the nvim-cmp plugin you have to install some external plugins
" ~/.config/nvim/init.nvim Plug 'hrsh7th/cmp-nvim-lsp' Plug 'hrsh7th/cmp-buffer' Plug 'hrsh7th/cmp-path' Plug 'hrsh7th/cmp-cmdline' Plug 'hrsh7th/nvim-cmp' Plug 'hrsh7th/vim-vsnip' after installing the server of your language you may need some Lua code to enable it
so you can use this code to copy & paste into your init.nvim file
Also, Don't forget to check this page to get the right server for your language
in my case I'll install rust-analyzer
$ sudo pacman -S rust-analyzer " ~/.config/nvim/init.nvim lua <<EOF -- Setup nvim-cmp. local cmp = require'cmp' cmp.setup({ snippet = { -- REQUIRED - you must specify a snippet engine expand = function(args) vim.fn["vsnip#anonymous"](args.body) -- For `vsnip` users. -- require('luasnip').lsp_expand(args.body) -- For `luasnip` users. -- require('snippy').expand_snippet(args.body) -- For `snippy` users. -- vim.fn["UltiSnips#Anon"](args.body) -- For `ultisnips` users. end, }, mapping = { ['<C-b>'] = cmp.mapping(cmp.mapping.scroll_docs(-4), { 'i', 'c' }), ['<C-f>'] = cmp.mapping(cmp.mapping.scroll_docs(4), { 'i', 'c' }), ['<C-Space>'] = cmp.mapping(cmp.mapping.complete(), { 'i', 'c' }), ['<C-y>'] = cmp.config.disable, -- Specify `cmp.config.disable` if you want to remove the default `<C-y>` mapping.
