[fzf](https://github.com/junegunn/fzf) changed my life, it can change yours too, if you allow it.

  </div>

## Rationale

What more can be said about [fzf](https://github.com/junegunn/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](https://www.youtube.com/watch?v=qgG5Jhi_Els) by
> [@samoshkin](https://github.com/samoshkin)**

This is my take on the original
[fzf.vim](https://github.com/junegunn/fzf.vim), written in lua for neovim 0.5,
it builds on the elegant
[nvim-fzf](https://github.com/vijaymarupudi/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, to name a few,
[telescope](https://github.com/nvim-telescope/telescope.nvim) or
[vim-clap](https://github.com/liuchengxu/vim-clap)?

As [@junegunn](https://github.com/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

- `Linux` or `MacOS`
- [`neovim`](https://github.com/neovim/neovim/releases) version > 0.5.0
- [`fzf`](https://github.com/junegunn/fzf) version > 0.24.0 **or**
  [`skim`](https://github.com/lotabout/skim) binary installed
- [nvim-web-devicons](https://github.com/kyazdani42/nvim-web-devicons)
  (optional)

### Optional dependencies

- [fd](https://github.com/sharkdp/fd) - better `find` utility
- [rg](https://github.com/BurntSushi/ripgrep) - better `grep` utility
- [bat](https://github.com/sharkdp/bat) - syntax highlighted previews when
  using fzf's native previewer
- [delta](https://github.com/dandavison/delta) - syntax highlighted git pager
  for git status previews
- [viu](https://github.com/atanunq/viu) - terminal image previews (needs to be
  configured via `previewer.builtin.extensions`)
- [ueberzug](https://github.com/seebye/ueberzug) - X11 image previews (needs to
  be configured via `previewer.builtin.extensions`)
- [nvim-dap](https://github.com/mfussenegger/nvim-dap) - for Debug Adapter
  Protocol (DAP) support


## Installation

Using [vim-plug](https://github.com/junegunn/vim-plug)

```vim
Plug 'ibhagwan/fzf-lua', {'branch': 'main'}
" optional for icon support
Plug 'kyazdani42/nvim-web-devicons'
```

Using [packer.nvim](https://github.com/wbthomason/packer.nvim)

```lua
use { 'ibhagwan/fzf-lua',
  -- optional for icon support
  requires = { 'kyazdani42/nvim-web-devicons' }
}
```
> **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):
> ```vim
> Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
> ```
> or with [packer.nvim](https://github.com/wbthomason/packer.nvim):
>```lua
>use = { 'junegunn/fzf', run = './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
:lua require('fzf-lua').files()
-- or using the `FzfLua` vim command:
:FzfLua files
```

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

which can be easily mapped to:
```vim
nnoremap <c-P> <cmd>lua require('fzf-lua').files()<CR>
```

or if using `init.lua`:
```lua
vim.api.nvim_set_keymap('n', '<c-P>',
    "<cmd>lua require('fzf-lua').files()<CR>",
    { noremap = true, silent = true })
```

## Customization

I tried to make it as customizable as possible, if you find you need to change something that isn’t below, open an issue and I’ll do my best to add it.

customization can be achieved by calling the `setup()` function or individually sending parameters to a builtin command, for exmaple:
```lua
:lua require('fzf-lua').files({ fzf_opts = {['--layout'] = 'reverse-list'} })
```

Consult the list below for available settings:
```lua
local actions = require "fzf-lua.actions"
require'fzf-lua'.setup {
  -- fzf_bin         = 'sk',            -- use skim instead of fzf?
                                        -- https://github.com/lotabout/skim

                                        -- can also be sent individually:
                                        -- `<any_function>.({ gl ... })`
  global_resume_query = true,           -- include typed query in `resume`?
  winopts = {
    -- split         = "belowright new",-- open in a split instead?
                                        -- "belowright new"  : split below
                                        -- "aboveleft new"   : split above

## 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:

  code
- [@lukas-reineke](https://github.com/lukas-reineke) for inspiring the
  solution after browsing his
