Auto-commands, keymaps, options¶

The three files under lua/config/ shape day-to-day editing.

`options.lua`¶

Loads before plugins (event: BeforeLazy). Highlights:

vim.loader.enable()                       -- byte-code cache
g.loaded_python3_provider = 0             -- no python3 provider
g.loaded_perl_provider   = 0
g.loaded_ruby_provider   = 0
g.loaded_node_provider   = 0

g.lazyvim_cmp = "auto"                    -- LazyVim default cmp (blink)
g.lazyvim_picker = "snacks"               -- Snacks picker over Telescope
g.autoformat = true                       -- format on save
g.editorconfig = true                     -- respect .editorconfig

g.gui_font_face = "Iosevka NF"
o.guifont = string.format("%s:h%s", g.gui_font_face, g.gui_font_size)

o.guicursor    = "n-v-c-sm:block,i-ci-ve:ver25,r-cr-o:hor20"
o.splitright   = true
o.splitbelow   = true
o.colorcolumn  = "80,120"                 -- rulers
o.list         = true                     -- show whitespace
o.spell        = true                     -- spell check on
o.showtabline  = 0                        -- no native bufferline
o.laststatus   = 3                        -- global statusline

The whitespace listchars use middle-dot for spaces and >— for tabs:

o.listchars:append({
  tab = ">—", multispace = "·",
  extends = ">", precedes = "<", lead = "·", trail = "·",
})

LSP logging is set to off because the log grows unboundedly when on.

`keymaps.lua`¶

Loaded on VeryLazy. Notable additions on top of LazyVim defaults:

Mode	Mapping	Action
n	`Tab`	Next buffer (uses bufferline if loaded).
n	`Shift`+`Tab`	Previous buffer.
n	`<`	Deindent (`<<`).
n	`>`	Indent (`>>`).
n	`Alt`+`S`	Save without formatting (`:noautocmd w`).
n	`+`	Increment number (`<C-a>`).
n	`-`	Decrement number (`<C-x>`).
n	`U` (capital U)	Redo (`<C-r>`).
n	`Ctrl`+`C`	Yank entire buffer.
n	`Ctrl`+`E`	Select all text.
n	++leader++ `!`	`zg` — add word under cursor to spell dictionary.
n	++leader++ ++at++	`zug` — remove word from spell dictionary.

Mappings are wrapped in a small map() helper that skips registration if a lazy.nvim handler already owns the key, avoiding accidental overrides.

`autocmds.lua`¶

Loaded on VeryLazy. Adds:

Auto-close ephemeral UI¶

When buffers of these filetypes lose focus, their windows close:

lazy, mason, lspinfo, toggleterm, notify

Leader disabled in those filetypes¶

In the same set plus floaterm, both <leader> and <localleader> are bound to <nop> so filetype-specific keybindings don't conflict with global leader mappings.

Quickfix not buflisted¶

The quickfix window doesn't show in :bnext / bufferline rotation.

Terminal sanity¶

In :terminal buffers: listchars cleared, no line numbers, no spell-check.

Trailing whitespace stripped on save¶

autocmd("BufWritePre", {
  pattern = { "*" },
  command = [[%s/\s\+$//e]],
})

Don't continue comments¶

formatoptions-=cro is applied on every BufEnter (both global and buffer-local) so newlines after a comment line never auto-insert a comment leader.

Relative number toggle¶

relativenumber is on in normal mode and off in insert mode, focus-lost, and command-line — implemented as a pair of autocmds in the numbertoggle group.
