Find And Replace plugin for neovim

Grug find! Grug replace! Grug happy!

✨ Features

  • Search using the full power of rg
  • Replace using almost the full power of rg. Some flags such as --binary and --json, etc. are blacklisted in order to prevent unexpected output. The UI will warn you and prevent replace when using such flags.
  • Open search results in quickfix list
  • Goto file/line/column of match when pressing <Enter> in normal mode on lines in the results output (keybind configurable).
  • Inline edit result lines and sync them back to their originating file locations using a configurable keybinding.
  • Manual/auto-save search history and reload



Rg teaching you it's ways



🤔 Philosophy

  1. strives for reduced mental overhead. All actions you can take are in your face. As much help as possible is in your face (some configurable). Grug often forget how to do capture groups or which flag does what.
  2. transparency. Does not try to hide away rg and shows error messages from it which are actually quite friendly when you mess up your regex. You can gradually learn rg flags or use existing knowledge from running it in the CLI. You can even input the --help flag to see the full rg help. Grug like!
  3. reuse muscle memory. Does not try to block any type of buffer edits, such as deleting lines, etc. It's very easy to get such things wrong and when you do, Grug becomes unable to modify text in the middle of writing a large regex. Grug mad!! Only ensures graceful recovery in order to preserve basic UI integrity (possible due to the magic of extmarks). Recovery should be simple undo away.
  4. uniformity. only uses one tool, rg, and does not combine with other tools like sed. One should not have to worry about compatibility differences when writing regexes. Additionally it opens the door to use to many fancy rg flags such as different regex engine that would not be possible in a mixed environment. Replacement is achieved by running rg --replace=... --passthrough on each file with configurable number of parallel workers.

⚡️ Requirements

Run :checkhealth grug-far if you see unexpected issues.

📦 Installation

Using lazy.nvim:

    config = function()
        ... options, see Configuration section below ...
        ... there are no required options atm...

⚙️ Configuration

grug-far.nvim comes with the following:

Note on the key mappings: By default, grug-far, will use <localleader> for it's keymaps as that is the vim recommended way for plugins. See

So to use that, make sure you have <localleader> configured. For example, to use , as the local leader:

vim.g.maplocalleader = ','

🚀 Usage

Opening and editing

You can open a new grug-far.nvim vertical split buffer with the :GrugFar command. But possibly best to map a keybind to it for easy triggering. Since it's just a buffer, you can edit in it as you see fit. The UI will try to guide you along and recover gracefully if you do things like ggVGd (delete all lines). Ultimately it leaves the power in your hands, and in any case recovery is just a few u taps away.

You can create multiple such buffers with potentially different searches, which will reflect in each buffer's title (configurable). The buffers should be visible in the buffers list if you need to toggle to them.

Searching and replacing

Search and replace is accomplished by simply typing text on appropriately marked lines. Search will happen in a debounced manner as you type. In the options, you can also specify a minimum number of characters that one has to enter before search is triggered. You can also specify a files filter to narrow down your search and more ripgrep flags to refine it further. Error messages from ripgrep when entering invalid flags and so on are displayed to guide you along.

Note: When replacing matches with the empty string, you will be prompted to confirm, as the change is not visible in the results area due to UI considering it just a search. If you would like to see the actual replacement in the results area, add --replace= to the flags.

Syncing results lines back to originating files

It is possible to sync the text of the lines in the results area back to their originating files. This operation is either done on the current cursor line (Sync Line), or on all lines (Sync All).

A sync will happen only if a line has changed in some way compared to the source file, so if there's either a replacement taking place or you have manually edited it.

Deleting result lines will cause them to be excluded from being synced by Sync All action. This can be a nice way to refine a replacement in some situations if you want to exclude a particular file or some particular matches.

If you don't edit the results list, Sync All and Replace have equivalent outcomes, except for one case. When you do multi-line replace with --multiline and --multiline-dot-all flags, sync won't work so you have to use replace. Essentially the difference it that Replace runs rg --replace=... --passthrough on each file and does not depend at all on what's in the results area. Sync All does a line by line sync based on what's in the results area.

Note: changing the <line-number>:<column>: prefix of result lines will disable sync for that line

Note: sync is disabled when doing multiline replacement (--multiline flag)

Note: if you would like sync to work when doing a replacement with empty string, please add --replace= to the flags.

Opening result lines in quickfix list

Result lines can be opened in the quickfix list. Deleting result lines will cause them not to be included.

Note: changing the <line-number>:<column>: prefix of result lines will remove lines from consideration

Note: quickfix list is disabled when doing multiline replacement (--multiline flag)


grug-far can keep track of your search history. This is done either by manually adding a history entry with History Add action or automatically on certain successful actions like Replace and Sync All.

When you would like to pick one of your history entries to reuse, you can use the History Open action to open the search history as a buffer. From there you can either pick an entry that will be auto-filled in.

Note that you can edit the history buffer and save just like any other buffer if you need to do some cleanup. The format of a history entry is:

<optional comment, ex: My special search>
Search: <text>
Replace: <text>
Files Filter: <text>
Flags: <text>

History entries are separated by one or more empty lines.

Note: grug-far will ignore lines that do not start with the prefixes above


If you inadvertently launched a wrong search/sync/replace, you can abort early using the Abort action.


When you are done, it is recommended to close the buffer with the configured keybinding (see Configuration section above) or just :bd in order to save on resources as some search results can be quite beefy in size. The advantage of using the Close action as opposed to just :bd is that it will ask you to confirm if there is a replace/sync in progress, as those would be aborted.


Note that grug-far.nvim buffers will have filetype=grug-far and history buffers will have filetype=grug-far-history if you need filter/exclude them in any situations.

⚒️ Lua API

For more control, you can programmatically open a grug-far buffer like so:


or if you would like to pre-fill current visual selection as the search text: (note, this will also set --fixed-strings flag as selection can contain special characters)


where opts will be merged with and override the global plugin options configured at setup time.

See here for all the available options

🥪 Cookbook

Launch with the current word under the cursor as the search string

:lua require('grug-far').grug_far({ prefills = { search = vim.fn.expand("<cword>") } })

Launch with the current file as a flag, which limits search/replace to it

:lua require('grug-far').grug_far({ prefills = { flags = vim.fn.expand("%") } })

Launch with the current visual selection, searching only current file

:<C-u>lua require('grug-far').with_visual_selection({ prefills = { flags = vim.fn.expand("%") } })
