Quickstart

To quickly test this plugin without changing your configuration run (will run in it's own sandbox with the default keybinds below):

[!NOTE] it's good practice to first read the script before running sh -c directly from the web

sh -c "$(curl -s https://raw.githubusercontent.com/ibhagwan/fzf-lua/main/scripts/mini.sh)"

Coming from fzf.vim?

Easy! run :FzfLua setup_fzfvim_cmds and use the same familiar commands used by fzf.vim, i.e. :Files, :Rg, etc.

Using the builtin fzf-vim profile will also create fzf.vim's user commands, i.e. require("fzf-lua").setup({ "fzf-vim" })

Rationale

What more can be said about fzf? It is the single most impactful tool for my command line workflow, once I started using fzf I couldn’t see myself living without it.

To understand fzf properly I highly recommended fzf screencast by @samoshkin

This is my take on the original fzf.vim, written in lua for neovim 0.5, it builds on the elegant nvim-fzf as an async interface to create a performant and lightweight fzf client for neovim that rivals any of the new shiny fuzzy finders for neovim.

Why Fzf-Lua

... and not telescope or any other vim/neovim household name?

As @junegunn himself put it, “because you can and you love fzf”.

If you’re happy with your current setup there is absolutely no reason to switch.

That said, without taking anything away from the greatness of other plugins I found it more efficient having a uniform experience between my shell and my nvim. In addition fzf has been a rock for me since I started using it and hadn’t failed me once, it never hangs and can handle almost anything you throw at it. That, and colorful file icons and git indicators!.

Dependencies

• neovim version > 0.5.0
• fzf version > 0.25 or skim binary installed
• nvim-web-devicons or mini.icons (optional)

Optional dependencies

• fd - better find utility
• rg - better grep utility
• bat - syntax highlighted previews when using fzf's native previewer
• delta - syntax highlighted git pager for git status previews
• nvim-dap - for Debug Adapter Protocol (DAP) support
• nvim-treesitter-context - for viewing treesitter context within the previewer
• render-markdown.nvim or markview.nvim - for rendering markdown files in the previewer

Below are a few optional dependencies for viewing media files (which you need to configure in previewer.builtin.extensions):

• chafa - terminal image previewer (recommended, supports most file formats)
• viu - terminal image previewer
• ueberzugpp - terminal image previewer using X11/Wayland child windows, sixels, kitty and iterm2

Windows Notes

• rg is required for grep and tags

• git for Windows is required for git (though installing git-bash|sh is not required).

• Installation of dependencies (fzf, rg, fd, etc) is possible via scoop, chocolatey or winget-cli

• Although almost everything works on Windows exactly as the *NIX/OSX check out the Windows README for known issues and limitations.

Installation

Using vim-plug

Plug 'ibhagwan/fzf-lua', {'branch': 'main'}
" optional for icon support
Plug 'nvim-tree/nvim-web-devicons'
" or if using mini.icons/mini.nvim
" Plug 'echasnovski/mini.icons'

Using packer.nvim

use { "ibhagwan/fzf-lua",
  -- optional for icon support
  requires = { "nvim-tree/nvim-web-devicons" }
  -- or if using mini.icons/mini.nvim
  -- requires = { "echasnovski/mini.icons" }
}

Using lazy.nvim

{
  "ibhagwan/fzf-lua",
  -- optional for icon support
  dependencies = { "nvim-tree/nvim-web-devicons" },
  config = function()
    -- calling `setup` is optional for customization
    require("fzf-lua").setup({})
  end
}

[!NOTE] if you already have fzf installed you do not need to install fzf or fzf.vim, however if you do not have it installed, you only need fzf which can be installed with (fzf.vim is not a requirement nor conflict):

Plug "junegunn/fzf", { "do": { -> fzf#install() } }

or with packer.nvim:

use = { "junegunn/fzf", run = "./install --bin" }

or with lazy.nvim

{ "junegunn/fzf", build = "./install --bin" }

Usage

Fzf-lua aims to be as plug and play as possible with sane defaults, you can run any fzf-lua command like this:

:lua require('fzf-lua').files()
-- or using the `FzfLua` vim command:
:FzfLua files

or with arguments:

:lua require('fzf-lua').files({ cwd = '~/.config' })
-- or using the `FzfLua` vim command:
:FzfLua files cwd=~/.config

which can be easily mapped to:

nnoremap <c-P> <cmd>lua require('fzf-lua').files()<CR>

or if using init.lua:

Neovim versions below 0.7 can use vim.api.nvim_set_keymap instead

vim.keymap.set("n", "<c-P>", require('fzf-lua').files, { desc = "Fzf Files" })
-- Or, with args
vim.keymap.set("n", "<c-P>", function() require('fzf-lua').files({ ... }) end, { desc = "Fzf Files" })

Resume

Resuming work from where you left off is as easy as:

:lua require('fzf-lua').resume()
-- or
:FzfLua resume

Alternatively, resuming work on a specific provider:

:lua require('fzf-lua').files({ resume = true })
-- or
:FzfLua files resume=true

Customization

ADVANCED CUSTOMIZATION : to create your own fzf-lua commands see Wiki/ADVANCED

Customization can be achieved by calling the setup() function (optional) or individually sending parameters to a builtin command, A few examples below:

Different fzf layout:

:lua require('fzf-lua').files({ fzf_opts = {['--layout'] = 'reverse-list'} })

Using files with a different command and working directory:

:lua require'fzf-lua'.files({ prompt="LS> ", cmd = "ls", cwd="~/<folder>" })

Using live_grep with git grep:

:lua require'fzf-lua'.live_grep({ cmd = "git grep --line-number --column --color=always" })

colorschemes with non-default window size:

:lua require'fzf-lua'.colorschemes({ winopts = { height=0.33, width=0.33 } })

Use setup() If you wish for a setting to persist and not have to send it using the call arguments, e.g:

require('fzf-lua').setup{
  winopts = {
    ...
  }
}

Can also be called from a .vim file:

lua << EOF
require('fzf-lua').setup{
  ...
}
EOF

Profiles

Conveniently, fzf-lua comes with a set of preconfigured profiles, notably:

Use :FzfLua profiles to experiment with the different profiles, once you've found what you like and wish to make the profile persist, send a string argument at the first index of the table sent to the setup function:

[!NOTE] setup can be called multiple times for profile "live" switching

require('fzf-lua').setup({'fzf-native'})

You can also start with a profile as "baseline" and customize it, for example, telescope defaults with bat previewer:

:lua require"fzf-lua".setup({"telescope",winopts={preview={default="bat"}}})

Combining of profiles is also available by sending table instead of string as the first argument:

:lua require"fzf-lua".setup({{"telescope","fzf-native"},winopts={fullscreen=true}})

See profiles for more info.

Insert-mode Completion

Fzf-lua comes with a set of completion functions for paths/files and lines from open buffers as well as custom completion, for example, set path/completion using <C-x><C-f>:

inoremap <c-x><c-f> <cmd>lua require("fzf-lua").complete_path()<cr>

Or in all modes using lua:

vim.keymap.set({ "n", "v", "i" }, "<C-x><C-f>",
  function() require("fzf-lua").complete_path() end,
  { silent = true, desc = "Fuzzy complete path" })

Or with a custom command and preview:

[!NOTE] only complete_file supports a previewer

vim.keymap.set({ "i" }, "<C-x><C-f>",
  function()
    require("fzf-lua").complete_file({
      cmd = "rg --files",
      winopts = { preview = { hidden = "nohidden" } }
    })
  end, { silent = true, desc = "Fuzzy complete file" })

Custom Completion

Every fzf-lua function can be easily converted to a completion function by sending complete = true in the options:

By default fzf-lua will insert the entry at the cursor location as if you used p to paste the selected entry.

require("fzf-lua").fzf_exec({"foo", "bar"}, {complete = true})

Custom completion is possible using a custom completion callback, the example below will replace the text from the current cursor column with the selected entry:

require("fzf-lua").fzf_exec({"foo", "bar"}, {
  -- @param selected: the selected entry or entries
  -- @param opts: fzf-lua caller/provider options
  -- @param line: originating buffer completed line
  -- @param col: originating cursor column location
  -- @return newline: will replace the current buffer line
  -- @return newcol?: optional, sets the new cursor column
  complete = function(selected, opts, line, col)
    local newline = line:sub(1, col) .. selected[1]
    -- set cursor to EOL, since `nvim_win_set_cursor`
    -- is 0-based we have to lower the col value by 1
    return newline, #newline - 1
  end
})

Default Options

If you're still having issues and/or questions do not hesitate to open an issue and I'll be more than happy to help.

Highlights

FzfLua conveniently creates the below highlights, each hlgroup can be temporarily overridden by its corresponding winopts option:

^{_{*Not a highlight group, RGB color from nvim_get_color_map}}

These can be easily customized either via the lua API:

:lua vim.api.nvim_set_hl(0, "FzfLuaBorder", { link = "FloatBorder" })

Or vimscript:

:hi! link FzfLuaBorder FloatBorder

If you wish to override a highlight without having to modify your colorscheme highlights, set the corresponding hls override or specify it directly via a call argument.

Temporary highlight override:

:lua require'fzf-lua'.files({ hls={preview_title="IncSearch"} })

Permanent global override via setup:

require('fzf-lua').setup {
  hls = { border = "FloatBorder" }
}

Fzf Colors

Fzf's terminal colors are controlled by fzf's --color flag which can be configured during setup via fzf_colors.

Set to true to have fzf-lua automatically generate an fzf colorscheme from your current Neovim colorscheme:

require("fzf-lua").setup({ fzf_colors = true })
-- Or in the direct call options
:lua require("fzf-lua").files({ fzf_colors = true })
:FzfLua files fzf_colors=true

Customizing the fzf colorscheme (see man fzf for all color options):

require('fzf-lua').setup {
  fzf_colors = {
    -- First existing highlight group will be used
    -- values in 3rd+ index will be passed raw
    -- i.e:  `--color fg+:#010101:bold:underline`
    ["fg+"] = { "fg" , { "Comment", "Normal" }, "bold", "underline" },
    -- It is also possible to pass raw values directly
    ["gutter"] = "-1"
  }
}

Conveniently, fzf-lua can also be configured using fzf.vim's g:fzf_colors, i.e:

-- Similarly, first existing highlight group will be used
:lua vim.g.fzf_colors = { ["gutter"] = { "bg", "DoesNotExist", "IncSearch" } }

However, the above doesn't allow combining both neovim highlights and raw args, if you're only using fzf-lua we can hijack g:fzf_colors to accept fzf-lua style values (i.e. table at 2nd index and 3rd+ raw args):

:lua vim.g.fzf_colors = { ["fg+"] = { "fg", { "ErrorMsg" }, "bold", "underline" } }

Credits

Big thank you to all those I borrowed code/ideas from, I read so many configs and plugin codes that I probably forgot where I found some samples from so if I missed your name feel free to contact me and I'll add it below:

• @vijaymarupudi for his wonderful nvim-fzf plugin which is at the core of this plugin
• @tjdevries for too many great things to list here and for borrowing some of his nvim-telescope provider code
• @lukas-reineke for inspiring the solution after browsing his dotfiles and coming across his fuzzy.lua , and while we're, also here for his great lua plugin indent-blankline
• @sindrets for borrowing utilities from his fantastic lua plugin diffview.nvim
• @kevinhwang91 for using his previewer code as baseline for the builtin previewer and his must have plugin nvim-bqf
