# NOE.ED Neovim Expert

Expert assistance for the NOE.ED Neovim configuration - a LazyVim-based setup with extensive customizations.

## Configuration Location

```
/Users/ed/.dotfiles/nvim/.config/nvim/
```

## Architecture Overview

NOE.ED uses a three-level plugin loading system (`lua/config/lazy.lua`):

1. **Core LazyVim** - `lazyvim.plugins`
2. **Custom plugins** - `lua/plugins/` (organized by category)
3. **Language configs** - `lua/plugins/languages/`

### Directory Structure

```

## Key Files

| File | Purpose |
|------|---------|
| `lazyvim.json` | Enabled LazyVim extras (32 extras) |
| `lazy-lock.json` | Plugin version lockfile |
| `lua/config/keymaps.lua` | Custom keybindings |
| `lua/plugins/ui/lualine.lua` | Custom statusline (253 lines) |
| `lua/plugins/ui/lualine/neoed.lua` | Theme adapter |

## Quick Reference

### Adding a New Plugin

Create file in appropriate category under `lua/plugins/`:

```lua
return {
  "author/plugin-name",
  event = "VeryLazy",
  opts = {
    -- options
  },
}
```

### Extending LSP Server Config

Create/edit file in `lua/plugins/languages/`:

```lua
return {
  {
    "neovim/nvim-lspconfig",
    opts = {
      servers = {
        servername = {
          settings = { servername = { option = value } },
        },
      },
    },
  },
}
```

### Adding a Keymap

Edit `lua/config/keymaps.lua`:

```lua
local set = vim.keymap.set
set("n", "<leader>xx", "<cmd>Command<cr>", { desc = "Description" })

-- For which-key groups:
local wk = require("which-key")
wk.add({ { "<leader>x", group = "Group Name", icon = { icon = "X", color = "blue" } } })
```

### Disabling a Plugin

Add to `lua/plugins/disabled.lua`:

```lua
return {
  { "plugin/name", enabled = false },
}
```
