Features

Search and replace in the current buffer using ripgrep.
Uses common regex syntax — no more dealing with arcane vim regex.
Incremental preview of matched strings and replacements, live count of matches.
Popup window instead of command line. This entails:
- Syntax highlighting of the regex.
- Editing with vim motions.
- No more dealing with delimiters.
Sensible defaults: entire buffer (%), all matches in a line (/g), case-sensitive (/I).
Range support
History of previous substitutions.
Performant: In a file with 5000 lines and thousands of matches, still performs blazingly fast.™
Regex101 integration: Open the planned substitution in a pre-configured regex101 browser-tab for debugging.
Quality-of-Life features: automatic prefill of the escaped cursorword, adaptive popup window width, visual emphasis of the active range, …

Syntax comparison:

# all three are equivalent

# vim's :substitute
:% s/\(foo\)bar\(\.\)\@!/\1baz/gI

# vim's :substitute (very magic mode)
:% s/\v(foo)bar(\.)@!/\1baz/gI

# rip-substitute
(foo)bar(?!\.)
$1baz

Installation

Requirements

ripgrep with pcre2 support
- homebrew: brew install ripgrep (already includes pcre2 by default)
- cargo: cargo install ripgrep --features "pcre2"
- You can also use this plugin without pcre2 by setting regexOptions.pcre2 = false in the plugin config.
nvim >= 0.10
:TSInstall regex (only needed for syntax highlighting)

-- lazy.nvim
{
	"chrisgrieser/nvim-rip-substitute",
	cmd = "RipSubstitute",
	keys = {
		{
			"<leader>fs",
			function() require("rip-substitute").sub() end,
			mode = { "n", "x" },
			desc = " rip substitute",
		},
	},
},

Configuration

require("rip-substitute").setup {
	popupWin = {
		title = " rip-substitute",
		border = "single",
		matchCountHlGroup = "Keyword",
		noMatchHlGroup = "ErrorMsg",
		hideSearchReplaceLabels = false,
		position = "bottom", -- "top"|"bottom"
	},
	prefill = {
		normal = "cursorWord", -- "cursorWord"|false
		visual = "selectionFirstLine", -- "selectionFirstLine"|false
		startInReplaceLineIfPrefill = false,
	},
	keymaps = {
		-- normal & visual mode
		confirm = "<CR>",
		abort = "q",
		prevSubst = "<Up>",
		nextSubst = "<Down>",
		openAtRegex101 = "R",
		insertModeConfirm = "<C-CR>", -- (except this one, obviously)
	},
	incrementalPreview = {
		matchHlGroup = "IncSearch",
		rangeBackdrop = {
			enabled = true,
			blend = 50, -- between 0 and 100
		},
	},
	regexOptions = {
		-- pcre2 enables lookarounds and backreferences, but performs slower
		pcre2 = true,
		---@type "case-sensitive"|"ignore-case"|"smart-case"
		casing = "case-sensitive",
		-- disable if you use named capture groups (see README for details)
		autoBraceSimpleCaptureGroups = true,
	},
	editingBehavior = {
		-- Experimental. When typing `()` in the `search` line, automatically
		-- adds `$n` to the `replace` line.
		autoCaptureGroups = false,
	},
	notificationOnSuccess = true,
}

[!NOTE] Any ripgrep config file set via RIPGREP_CONFIG_PATH is ignored by this plugin.

Usage

lua function

vim.keymap.set(
	{ "n", "x" },
	"<leader>fs",
	function() require("rip-substitute").sub() end,
	{ desc = " rip substitute" }
)

Normal mode: prefills the cursorword.
Visual mode: prefills the selection.
Visual line mode: replacements are only applied to the selected lines (the selection is used as range).

Ex command
Alternatively, you can use the ex command :RipSubstitute, which also accepts a range argument. Note that when using the ex command, visual mode and visual line mode both pass a range. To prefill the current selection, you therefore need to use the lua function.

" Substitute in entire file. Prefills the cursorword.
:RipSubstitute

" Substitute in line range of the visual selection.
:'<,'>RipSubstitute

" Substitute in given range (in this case: current line to end of file).
:.,$ RipSubstitute

You can also pass a prefill for the search value, in which case the prefill is not escaped.

:RipSubstitute prefilled string

Advanced

autoBraceSimpleCaptureGroups
A gotcha of ripgrep's regex syntax is that it treats $1a as the named capture group "1a" and not as the first capture group followed by the letter "a." (See ripgrep's man page on --replace for details.)

If regexOptions.autoBraceSimpleCaptureGroups = true (the default), rip-substitute automatically changes $1a to ${1}a, to make writing the regex more intuitive. However, if you regularly use named capture groups, you may want to disable this setting.

Filetype
The popup window uses the filetype rip-substitute. This can be useful, for instance, to disable auto-pairing plugins in the popup window.

Limitations

--multiline and various other flags are not supported yet.
This plugin only searches the current buffer. To search and replace in multiple files via ripgrep, use grug-far.nvim.
