fzf <https://github.com/junegunn/fzf> changed my life, it can change yours too,
if you allow it.
------------------------------------------------------------------------------
RATIONALE *fzf-lua-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 couldnt 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 *fzf-lua-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 youre 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
hadnt failed me once, it never hangs and can handle almost anything you
throw at it. That, and colorful file icons and git indicators!.
------------------------------------------------------------------------------
DEPENDENCIES *fzf-lua-dependencies*
- `Linux` or `MacOS` only, see nvim-fzf's How it
works <https://github.com/vijaymarupudi/nvim-fzf#How-it-works>
- `fzf` <https://github.com/junegunn/fzf> or
`skim` <https://github.com/lotabout/skim> binary installed
- nvim-fzf <https://github.com/vijaymarupudi/nvim-fzf>
- nvim-web-devicons <https://github.com/kyazdani42/nvim-web-devicons>
(optional)
OPTIONAL DEPENDENCIES *fzf-lua-optional-dependencies*
Recommended optional utilities:
- fd <https://github.com/sharkdp/fd> - better performance `find` utility
- bat <https://github.com/sharkdp/bat> - for colorful syntax highlighted previews
- ripgrep <https://github.com/BurntSushi/ripgrep> - for better grep-like searches
------------------------------------------------------------------------------
INSTALLATION *fzf-lua-installation*
Using vim-plug <https://github.com/junegunn/vim-plug>
>
Plug 'ibhagwan/fzf-lua'
Plug 'vijaymarupudi/nvim-fzf'
Plug 'kyazdani42/nvim-web-devicons'
<
Using packer.nvim <https://github.com/wbthomason/packer.nvim>
>
use { 'ibhagwan/fzf-lua',
requires = {
'vijaymarupudi/nvim-fzf',
'kyazdani42/nvim-web-devicons' } -- optional for icons
}
<
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 <https://github.com/wbthomason/packer.nvim>:
>
use = { 'junegunn/fzf', run = './install --bin', }
<
------------------------------------------------------------------------------
USAGE *fzf-lua-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 :
>
vim.api.nvim_set_keymap('n', '<c-P>',
"<cmd>lua require('fzf-lua').files()<CR>",
{ noremap = true, silent = true })

CUSTOMIZATION *fzf-lua-customization*
I tried to make it as customizable as possible, if you find you need to change
something that isnt below, open an issue and Ill 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 require('fzf-lua').files({ fzf_opts = {['--layout'] = 'reverse-list'} })
<
Consult the list below for available settings:
>

CREDITS *fzf-lua-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 <https://github.com/vijaymarupudi/> for his wonderful
nvim-fzf <https://github.com/vijaymarupudi/nvim-fzf> plugin which is in the
core of this plugin

list here and for borrowing some of his
nvim-telescope <https://github.com/nvim-telescope/telescope.nvim> provider
code
- @lukas-reineke <https://github.com/lukas-reineke> for inspiring the
solution after browsing his
dotfiles <https://github.com/lukas-reineke/dotfiles> and coming across his
fuzzy.lua <https://github.com/lukas-reineke/dotfiles/blob/master/vim/lua/fuzzy.lua>
, and while we're, also here for his great lua plugin
