:set diffopt+=iwhite,algorithm:patience
When whitespace-only churn and noisy line matching make diffs hard to review, tuning diffopt can dramatically improve signal.
:set timeoutlen=300 ttimeoutlen=10
If key mappings feel laggy, many users reduce timeoutlen and stop there.
config #config #mappings #terminal #performance #insert-mode
:set grepformat=%f:%l:%c:%m
When :grep output does not land cleanly in quickfix, the parser format is usually the missing piece.
:set diffopt+=algorithm:patience,indent-heuristic,linematch:60
Default diff settings can produce noisy hunks when code is moved, re-indented, or lightly refactored.
:set sessionoptions-=curdir
When you restore a session with :source Session.
:set viewoptions-=options
When you use :mkview and :loadview, Vim stores more than folds and cursor position.
:set completeopt=menuone,noinsert,noselect
When completion inserts text too early, you lose control over what gets committed and where undo breakpoints land.
:set shortmess+=c
Insert-mode completion can spam the command line with status text like "match 1 of N" and related prompts.
config #config #completion #command-line #options #insert-mode
:set diffopt+=algorithm:histogram,hiddenoff
Default diff behavior is fine for small changes, but larger refactors often produce noisy hunks and annoying warnings about hidden buffers.
:set cedit=<C-y>
Vim's command-line window is invaluable for editing long : commands, search patterns, and complex substitutions with normal-mode tools.
:set sessionoptions+=globals
By default, :mksession restores windows, buffers, and many editor states, but it skips most global variables.
:set jumpoptions=stack,view
By default, jump navigation can feel lossy in long files: you jump back, but folds, topline, and viewport context do not always match what you were looking at b
:set grepprg=rg\ --vimgrep\ --smart-case\ --hidden\ --glob\ !.git
Vim's :grep becomes much more useful when grepprg is tuned for ripgrep and quickfix-compatible output.
:set shada='200,<1000,s100,h
Default ShaDa settings are conservative, which can make long-running workflows lose useful context between sessions.
:set shada
Neovim's ShaDa (Shared Data) file replaces Vim's viminfo and persists session state across restarts — marks, registers, command history, search history, jump
:set listchars=
The listchars option controls exactly which invisible characters Vim highlights when list mode is active.
:set makeprg=
The makeprg option defines the command that :make runs.
function! {name}#{funcname}() in autoload/{name}.vim
Vim's autoload mechanism lets you place functions in autoload/*.
:set viewoptions=cursor,folds,slash,unix
The viewoptions setting is a comma-separated list that determines exactly what :mkview (and the auto-save view pattern) stores in a view file.
:set wildmode=longest:full,full
The wildmode option controls what happens when you press in the command line.
