vimscript config

If vimscript is your jam I'm going to assume you already have some experience configuring Neovim. So I'm going to show you a minimal config that you can copy to your own init.vim.

Note that after you install a language server with mason.nvim there is a good chance the server won't be able to initialize correctly the first time. Try to "refresh" the file with the command :edit, and if that doesn't work restart Neovim.

Make sure you have Neovim v0.8 or greater and download vim-plug (the plugin manager) before you copy this code into your config.

call plug#begin()
  Plug 'neovim/nvim-lspconfig'
  Plug 'williamboman/mason.nvim'
  Plug 'williamboman/mason-lspconfig.nvim'
  Plug 'hrsh7th/nvim-cmp'
  Plug 'hrsh7th/cmp-nvim-lsp'
  Plug 'L3MON4D3/LuaSnip'
  Plug 'VonHeikemen/lsp-zero.nvim', {'branch': 'v3.x'}
call plug#end()
