Neovim init.lua Changes

All changes made to ~/.config/nvim/init.lua.

Current file: init.lua

Colorscheme

Replaced folke/tokyonight.nvim (tokyonight-night) with RRethy/base16-nvim (base16-one-light — subdued light theme based on Atom One Light).

Treesitter

Fixed nvim-treesitter config error (attempt to call field 'install' (a nil value)). The lazy-lock.json had a pinned commit from the archived master branch instead of main. Updated the lock file to the correct main branch commit (544320a9) where require('nvim-treesitter').install() exists.

Options

Setting	Value	Purpose
vim.o.wrapscan	false	Don't wrap search past end of file
vim.o.wildmode	'list:longest'	Tab completion: list matches, complete longest common string
vim.o.wildmenu	false	Disable wildmenu (was overriding wildmode)
vim.o.tabstop	4	Tab display width of 4 columns
listchars.tab	' '	Tabs render as plain spaces (invisible)

Keybindings

Key	Action	Description
Y	:e#<CR>	Switch to alternate (last edited) buffer
<C-x>	:bd<CR>	Close current buffer
<C-a>	Telescope buffers	Find existing buffers (fuzzy picker)
<space>so	Telescope live grep	Grep only code files (go, rs, tf, sh, py, toml, mk, bash, sql, Makefile)
<space>sw	Telescope grep_string	Search word under cursor in code files only (same glob filter as <space>so)
<C-u>	:res +6	Increase split height by 6
<C-d>	:res -6	Decrease split height by 6
;;	Copy path to clipboard	Copy current buffer path (as opened) to system clipboard
<space>sc	Telescope commands	Search and execute Ex commands
<Tab> (Telescope)	Toggle selection	Mark/unmark item in Telescope results, move up
<S-Tab> (Telescope)	Toggle selection	Mark/unmark item in Telescope results, move down
<M-q> (Telescope)	Selected → quickfix	Send only selected items to quickfix list and open it (Telescope default)
<space>gd	:DiffviewOpen	Git diff all files against HEAD
<space>gh	:DiffviewFileHistory %	Git commit history for current file

Commands

Command	Action
:Vrc	Open ~/.config/nvim/init.lua

which-key

Customized from kickstart defaults:

• delay = 250 — show which-key popup after 250ms (kickstart default is 0)
• Trimmed spec: removed <leader>c (Code), <leader>d (Document), <leader>r (Rename), <leader>w (Workspace) groups
• Added { 'gr', group = 'LSP Actions', mode = { 'n' } } group
• Added visual mode to <leader>s (Search) group

blink.cmp (completion plugin)

Customized cmdline completion to fix wildmode conflict and improve UX:

cmdline = {
  keymap = {
    ['<Tab>'] = { 'select_and_accept', 'fallback' },
    ['<C-n>'] = { 'select_next', 'fallback' },
    ['<C-p>'] = { 'select_prev', 'fallback' },
  },
  completion = {
    list = { selection = { preselect = true, auto_insert = true } },
    menu = { auto_show = true },
  },
},

• Top match auto-selected and auto-inserted
• <Tab> accepts the selection (instead of <C-y>)
• <C-n>/<C-p> to cycle matches

Added 'buffer' to completion sources so <C-n> also completes words from the current buffer:

sources = {
  default = { 'lsp', 'path', 'snippets', 'buffer' },
},

New Plugins

Plugin	Purpose
sindrets/diffview.nvim	Side-by-side git diff viewer for all files, file history
rafamadriz/friendly-snippets	Premade snippets for many languages (Go, Rust, etc.)

Diff Colors

Fixed unreadable diff highlights (dark backgrounds on light theme). Added termguicolors = true and overrode DiffAdd, DiffDelete, DiffChange, DiffText with light pastel backgrounds via ColorScheme autocmd.

Terminal Title

Set terminal title to NVIM via vim.o.title = true and vim.o.titlestring = 'NVIM'.

LSP Servers

Added to the servers table (user change):

• gopls
• pyright
• rust_analyzer
• stylua

Change Log

2026-03-16

• <space>sw restricted to code files: Changed from bare builtin.grep_string to a wrapped function with glob_pattern filter matching the same file types as <space>so (*.go, *.rs, *.tf, *.sh, *.py, *.toml, *.mk, *.bash, *.sql, Makefile). Previously searched all files in the tree.
• Buffer word completion: Added 'buffer' to blink.cmp sources.default (was { 'lsp', 'path', 'snippets' }). <C-n> now also suggests words from the current buffer, not just LSP/snippets/paths.
• Documentation sync: Added previously undocumented <space>sc (search commands) keybinding and which-key customizations (delay 250ms, trimmed spec, gr LSP Actions group).
• Telescope selection → quickfix: Mapped <Tab>/<S-Tab> to toggle selection in Telescope results. <C-q> sends all results to quickfix (default), <M-q> (Alt-q) sends only selected items (also default).

2026-03-05

• Initial setup: colorscheme, treesitter fix, options, keybindings, commands, blink.cmp cmdline config, new plugins, diff colors, terminal title, LSP servers.
