# Building a Modern Neovim Config Neovim has become my editor of choice due to its blazing speed and infinite extensibility. In this post, I'll dissect my configuration, which focuses on a clean UI, robust LSP support, and seamless navigation. ## The Architecture: Lazy.nvim I use **[lazy.nvim](https://github.com/folke/lazy.nvim)** as my plugin manager. It allows for a highly modular structure where every plugin category gets its own file. My `init.lua` is surprisingly simple. It bootstraps `lazy` and imports the plugin specifications: ```lua -- init.lua require("lazy").setup({ { import = "plugins.core" }, -- Themes, Dashboard { import = "plugins.ui" }, -- Neo-tree, Noice { import = "plugins.editing" }, -- Treesitter, Comments { import = "plugins.completion" }, -- Cmp, Snippets { import = "plugins.lsp" }, -- LSP Config { import = "plugins.formatting" }, -- Conform, None-ls { import = "plugins.utilities" }, -- Copilot, Which-key }, { defaults = { lazy = true }, checker = { enabled = false }, }) ``` ## Core Settings Before loading plugins, I set reasonable defaults in `lua/core/options.lua`. A few highlights include: - **`relativenumber = true`**: Essential for relative jumps. - **`clipboard = 'unnamedplus'`**: Syncs the system clipboard with Neovim. - **`scrolloff = 4`**: Keeps context visible above and below the cursor. - **`undofile = true`**: Persists undo history even after closing the file. ## Keymaps & Workflow I've mapped my **Leader key** to ``, which is ergonomic and standard for modern setups. You can find my full list in `lua/core/keymaps.lua`. ### Window Management I avoid using the mouse for window resizing or navigation: ```lua -- Resize with arrows vim.keymap.set("n", "", ":resize -2", opts) vim.keymap.set("n", "", ":resize +2", opts) -- Navigate splits using Leader + hjkl vim.keymap.set("n", "h", ":wincmd h", opts) vim.keymap.set("n", "l", ":wincmd l", opts) ``` ### File Operations Quick saving and quitting are muscle memory: ```lua vim.keymap.set("n", "s", "w", { desc = "Save file" }) vim.keymap.set("n", "q", "q", { desc = "Exit vim" }) ``` ## The Visual Stack Aesthetics play a huge role in productivity. I use the **GitHub Dark Default** theme via `github-nvim-theme` to match the rest of my developer environment. For the interface, I use: - **Neo-tree**: A file explorer that supports git status and icons. - **Lualine**: A fast and configurable status line. - **Noice.nvim**: Replaces the command line with nice popups and notifications. ## Intelligence: LSP & Completion My IDE-like features are powered by **Native LSP** and **nvim-cmp**. I use `mason.nvim` to manage language servers like `clangd` (C++), `pyright` (Python), and `ts_ls` (TypeScript). Formatting is handled by `conform.nvim`, which ensures my code is always clean on save. ```lua -- lua/plugins/formatting.lua format_on_save = function(bufnr) return { timeout_ms = 500, lsp_fallback = true } end ``` I've also integrated **GitHub Copilot** for AI-powered suggestions, mapped to `` for seamless acceptance. ## Conclusion This configuration strikes a balance between a minimal editor and a full-blown IDE. It starts fast, looks great, and provides all the tools I need for heavy coding sessions in C++, Lua, or Web Development.
