Question 1

Can you create a minimal Lazy.nvim setup with LSP, completion, Treesitter, and formatting?

Accepted Answer

Yes—here is a compact baseline you can drop into init.lua. It bootstraps Lazy, adds lspconfig, cmp, treesitter, mason, and none-ls with format-on-save.

```
-- Bootstrap Lazy.nvim
local lazypath = vim.fn.stdpath('data') .. '/lazy/lazy.nvim'
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ 'git','clone','--filter=blob:none','https://github.com/folke/lazy.nvim.git','--branch=stable', lazypath })
end
vim.opt.rtp:prepend(lazypath)

require('lazy').setup({
  {'neovim/nvim-lspconfig'},
  {'williamboman/mason.nvim', build = ':MasonUpdate' },
  {'williamboman/mason-lspconfig.nvim'},
  {'hrsh7th/nvim-cmp'}, {'hrsh7th/cmp-nvim-lsp'}, {'L3MON4D3/LuaSnip'},
  {'nvim-treesitter/nvim-treesitter', build = ':TSUpdate'},
  {'nvimtools/none-ls.nvim'},
})

-- LSP + completion
local lsp = require('lspconfig')
local cmp_cap = require('cmp_nvim_lsp').default_capabilities()
require('mason').setup()
require('mason-lspconfig').setup({ ensure_installed = { 'lua_ls','tsserver','pyright' } })
require('mason-lspconfig').setup_handlers({ function(server)
  lsp[server].setup({ capabilities = cmp_cap })
end })

-- Treesitter basics
require('nvim-treesitter.configs').setup({ highlight = { enable = true }, indent = { enable = true } })

-- Formatting (none-ls)
local null = require('null-ls')
null.setup({ sources = { null.builtins.formatting.prettier, null.builtins.formatting.stylua } })

-- Format on save
vim.api.nvim_create_autocmd('BufWritePre', { callback = function()
  vim.lsp.buf.format({ async = false })
end })
```
Tip: replace servers/formatters with what you actually use and set stylua/prettier configs in your repo.

Question 2

How do you help diagnose LSP issues like missing hover or broken formatting?

Accepted Answer

I’ll guide you through targeted checks and fixes:
1) Verify server state: run :LspInfo and :checkhealth; confirm the buffer’s filetype matches server capabilities.
2) Install/update servers: use Mason ( :Mason ) and ensure correct pathing on Windows (check PowerShell execution policy) or macOS/Linux (PATH to Mason bin).
3) Capability mismatches: ensure cmp-nvim-lsp augments capabilities; disable conflicting formatters (e.g., two format-on-save autocommands) or set per-client formatting with vim.lsp.buf.format({ filter = ... }).
4) Minimal repro: start with nvim --clean and load only lspconfig + one server; add plugins back gradually.
5) Logs: enable LSP logs via :lua vim.lsp.set_log_level('debug') and inspect ~/.local/state/nvim/lsp.log.

Question 3

What are robust patterns for keymaps without conflicts?

Accepted Answer

Use vim.keymap.set with descriptive desc labels and a consistent Leader scheme: ``` vim.g.mapleader = ' ' local map = function(mode, lhs, rhs, desc) vim.keymap.set(mode, lhs, rhs, { silent = true, noremap = true, desc = desc }) end map('n','ff', function() require('telescope.builtin').find_files() end, 'Find files') map('n','fg', function() require('telescope.builtin').live_grep() end, 'Live grep') map('n','rn', vim.lsp.buf.rename, 'LSP rename') map({'n','v'},'ca', vim.lsp.buf.code_action, 'Code action') ``` Tips: keep modes explicit, avoid remapping space-heavy defaults you use, group by prefix (f for "find", g for "git"), and add which-key for discoverability.

Question 4

How can you help me master macros efficiently?

Accepted Answer

I provide repeatable recipes and pitfalls to avoid:
• Record: press q + register (e.g., qa), perform edits, then press q to stop.
• Replay: @a once, @@ to repeat the last macro. Use a count like 10@a.
• Edit macros: :let @a = '...'; or paste with Ctrl-r a in command-line to tweak.
• Apply to lines: :%normal @a or :'<,'>normal @a for visual ranges.
• Make macros resilient: navigate with f/t motions and text objects instead of absolute moves; add marks (mA) if you need to jump back.

Question 5

Can you optimize startup and runtime performance?

Accepted Answer

Yes—here’s a quick checklist:
• Enable Lua module loader early: `vim.loader.enable()` (Neovim 0.9+).
• Lazy-load plugins by event/ft/cmd; profile with :Lazy profile and prune unused specs.
• Disable unused providers: `vim.g.loaded_perl_provider = 0`, etc.
• Reduce redraw: set `vim.o.lazyredraw = true` during heavy macros; keep statuscolumn/lightline themes lean.
• Treesitter: limit heavy modules per ft; disable additional regex highlighting with `additional_vim_regex_highlighting = false`.
• Keep LSPs fast: trim large workspace folders, enable root_dir filters, and prefer local tools via Mason.
