Neovim

Neovim Configuration

Config lives at ~/.dotfiles/.config/nvim/, symlinked by GNU Stow, namespaced under kriscard/. Plugin manager is lazy.nvim.

Config Location

~/.dotfiles/.config/nvim/
├── init.lua                  # Entry point — sources all modules
├── lua/kriscard/
│   ├── core/
│   │   ├── options.lua       # vim.opt settings
│   │   ├── keymaps.lua       # vim.keymap.set with {desc = "..."}

│       └── *.lua

Stow package: cd ~/.dotfiles && stow nvim (or whatever the package name is — check ls ~/.dotfiles).

First: classify the branch

• Healthcheck or broken config → use Key Workflows; load references/config.md if needed.
• Plugin add/remove/replacement → load references/plugins.md.
• Startup/performance → load references/performance.md.
• Whole-dotfiles health issue → route to audit; non-Neovim terminal config → route to shell-env.

Do not load all references.

Key Workflows

Validate config

:checkhealth          " full diagnostic
:checkhealth lazy     " plugin manager health
:checkhealth nvim-treesitter
:Lazy                 " plugin status dashboard

Done when health output is captured, any failing provider/plugin is named, and each issue has a fix or next diagnostic command.

Add a plugin

1. Create or edit a file in lua/kriscard/plugins/.
2. Return a lazy.nvim spec table.
3. Save — lazy.nvim auto-detects changes on next start, or run :Lazy sync.
4. Run :checkhealth <plugin> when the plugin provides health checks.

Done when the spec is in the Stow-managed source path, lazy.nvim can sync/load it, and any keymaps/commands include lazy-load boundaries.

Diagnose performance

Run :Lazy profile to see per-plugin load times. For CLI measurement:

nvim --headless --startuptime /tmp/nvim.log +q && sort -k2 -n /tmp/nvim.log | tail -20

Done when before/after startup measurements are recorded, top slow plugins or config files are named, and each recommendation maps to a lazy.nvim event, cmd, keys, or ft boundary or is marked needs deeper profiling.

Fix broken plugin

Move from least destructive to most destructive:

1. :Lazy log — inspect recent install/update errors.
2. :messages — capture Lua errors after startup.
3. :Lazy sync — retry install/update when the error indicates missing or stale plugin state.
4. :Lazy clean — remove unused plugins only after confirming they are no longer referenced.
5. Delete ~/.local/share/nvim/lazy/<plugin> only as a last resort to force reinstall.

Done when the error is reproduced or log output is captured, the least destructive applicable repair has run, and the next startup/checkhealth result is recorded.

Quick Checks (run on every audit)

• Plugins use opts = {} instead of config = function() require("x").setup({}) end where possible
• Keymaps include {desc = "..."} for which-key integration
• LSP plugins are not loaded eagerly (use event = "BufReadPre")
• No duplicate keymaps (:verbose map <key> to check)
• vim.loader.enable() called in init.lua (bytecode cache, free perf)

Completion gate: do not declare Neovim work done until the changed source path, validation command, and result are reported.
