Standard Module Pattern

All configuration modules follow the M.setup() pattern:

local M = {}

M.setup = function()
  -- Configuration logic here
end

return M

Plugin Management (lazy.nvim)

Adding a New Plugin

Add to the appropriate category file in lua/plugins/specs/:

-- lua/plugins/specs/tools.lua
return {
  -- Existing plugins...

  {
    "author/plugin-name",
    event = "VeryLazy",           -- Loading strategy
    dependencies = { "dep/name" }, -- Required plugins
    opts = {
      -- Plugin options
    },
    config = function(_, opts)
      require("plugin-name").setup(opts)
    end,
  },
}

Loading Strategies

Plugin Commands

LSP Configuration

See references/lsp.md for complete LSP reference.

LSP Stack

mason.nvim (installer)
    ├── mason-lspconfig.nvim → nvim-lspconfig
    ├── mason-tool-installer.nvim (auto-install)
    └── mason-nvim-dap.nvim → nvim-dap

nvim-lspconfig
    ├── blink.cmp (completion)
    ├── conform.nvim (formatting)
    ├── nvim-lint (linting)
    └── trouble.nvim (diagnostics)

Adding an LSP Server

-- In lua/plugins/specs/lsp.lua, add to mason-tool-installer list:
ensure_installed = {
  "lua_ls",
  "pyright",
  "your_new_server",  -- Add here
}

-- Configure in lspconfig setup:
servers = {
  your_new_server = {
    settings = {
      -- Server-specific settings
    },
  },
}

LSP Keybindings

Keybindings

See references/keybindings.md for complete reference.

Core Navigation

Adding Keybindings

-- In lua/config/keymaps.lua M.setup():
vim.keymap.set('n', '<leader>xx', function()
  -- Your action
end, { desc = 'Description for which-key' })

-- Or in a plugin spec:
keys = {
  { "<leader>xx", "<cmd>Command<CR>", desc = "Description" },
}

Debugging (DAP)

See references/debugging.md for complete reference.

DAP Keybindings

Adding a Debug Adapter

-- In lua/plugins/specs/debug.lua
local dap = require("dap")

dap.adapters.your_adapter = {
  type = "executable",
  command = "path/to/adapter",
}

dap.configurations.your_filetype = {
  {
    type = "your_adapter",
    request = "launch",
    name = "Launch",
    program = "${file}",
  },
}

Performance Optimization

Startup Optimization Layers

Profiling Startup

:Lazy profile

Deferred Loading Pattern

-- In init.lua
vim.defer_fn(function()
  require('config.options').setup()
  require('config.keymaps').setup()
  require('config.autocmds').setup()
end, 0)

Common Tasks

Adding an Autocommand

-- In lua/config/autocmds.lua M.setup():
vim.api.nvim_create_autocmd("FileType", {
  pattern = { "markdown", "text" },
  callback = function()
    vim.opt_local.wrap = true
    vim.opt_local.spell = true
  end,
})

Adding Vim Options

-- In lua/config/options.lua M.setup():
vim.opt.your_option = value

Creating a Utility Function

-- In lua/utils/init.lua
local M = {}

M.your_function = function(args)
  -- Implementation
end

return M

-- Usage: require('utils').your_function(args)
