Introduction to LSP

Language Server Protocol (LSP) is a powerful feature that provides intelligent code completion, diagnostics, and more. NyxVim makes it easy to configure and use LSP for various programming languages.
Before diving into LSP configuration, it’s recommended to familiarize yourself with the basics of LSP and its benefits for development.

​
Setting Up LSP Servers

To get started with LSP configuration in NyxVim:
  1. Review the lspconfig repository for general LSP setup information.
  2. Check the configs.md to ensure your language’s LSP server is supported.

​
Plugin Configuration

To modify the lspconfig setup, add the following to your plugin configuration: 
{
  "neovim/nvim-lspconfig",
   config = function()
      require("nyxvim.configs.lspconfig").defaults()
      require "configs.lspconfig"
   end,
},

​
LSP Server Configuration

Create a file named configs/lspconfig.lua with the following structure: 
local configs = require("nyxvim.configs.lspconfig")

local on_attach = configs.on_attach
local on_init = configs.on_init
local capabilities = configs.capabilities

local lspconfig = require "lspconfig"
local servers = { "html", "cssls", "clangd"}

for _, lsp in ipairs(servers) do
  lspconfig[lsp].setup {
    on_init = on_init,
    on_attach = on_attach,
    capabilities = capabilities,
  }
end
The loop in the configuration above allows you to set up multiple LSP servers efficiently. Without it, you’d need to manually configure each server individually.

​
Mason.nvim Integration

mason.nvim is a powerful tool for managing LSP servers, DAP servers, linters, and formatters in Neovim. To install LSP servers and tools using Mason:
  1. Open NyxVim
  2. Run the command :MasonInstallAll
After installing binaries with Mason, you’ll need to configure them to work properly with LSP, conform.nvim, nvim-lint, nvim-dap, etc. The specific configuration depends on what you’ve installed.
NyxVim provides language configuration for Lua out of the box. For other languages, you’ll need to set up the configuration yourself.

​
Customizing LSP Behavior

You can customize LSP behavior by modifying the on_attach function or adjusting server-specific settings. Here’s an example of how you might customize the HTML LSP server: 
lspconfig.html.setup {
  on_attach = on_attach,
  capabilities = capabilities,
  filetypes = { "html", "templ" },  -- Add support for templ files
  init_options = {
    configurationSection = { "html", "css", "javascript" },
    embeddedLanguages = {
      css = true,
      javascript = true
    },
  }
}

​
Troubleshooting

If you encounter issues with LSP:
  1. Check the :LspInfo command output for server status
  2. Verify that the LSP server is installed correctly
  3. Review your configuration for any errors
Use :checkhealth in NyxVim to diagnose potential issues with your setup, including LSP-related problems.
