✨ Features

Colors/icons, Windows and modern Neovim features support.
Updates on every keystroke of user query and selection.
Multiple variants to avoid manual input:
- Search by visual select.
- Search by cursor word.
- Search by yank text.
- Search by resume last search.
Multiple data sources to avoid restart search flow:
- Exclude or include hiddens/ignores when searching files.
- Local or remote when searching git branches.
- Whole workspace or current buffer only when searching diagnostics.
- ...
And a lot more.

Please see Demo for more use cases.

✅ Requirements

[!NOTE]

This plugins supports latest stable and (possibly) nightly Neovim version.

Neovim ≥ 0.10.
fzf.
nerd-fonts (optional for icons).
curl (optional for preview window label).
rg (optional for live grep, by default use grep).
fd (optional for find files, by default use find).
bat (optional for preview files, by default use cat).
git (mandatory for all git commands).
delta (optional for preview git diff, show, blame).
lsd/eza (optional for file explorer, by default use ls).

Windows

Besides those rust-written commands mentioned above (rg/fd/bat), Windows users will have to install the linux shell environment and core utils, since basic shell commands such as echo, mkdir are internally required.

There're many ways to install portable linux shell and core utils on Windows, personally I would recommend below two methods:

Git for Windows

Install with the below 3 options:

In Select Components, select Associate .sh files to be run with Bash.
In Adjusting your PATH environment, select Use Git and optional Unix tools from the Command Prompt.
In Configuring the terminal emulator to use with Git Bash, select Use Windows's default console window.

After this step, git.exe and builtin linux commands(such as echo.exe, ls.exe, curl.exe) will be available in %PATH%.

scoop

Run below powershell commands:

# scoop
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
irm get.scoop.sh | iex

scoop bucket add extras
scoop install git           # git, bash, sh
scoop install mingw         # echo, grep, find, curl, ls, cat
scoop install coreutils     # echo, grep, find, curl, ls, cat

Fix conflicts between embedded commands from `C:\Windows\System32` and linux commands

Windows actually already provide some builtin commands (find.exe, bash.exe) in C:\Windows\System32 (or %SystemRoot%\system32), but they are not the linux commands they are named after, while could override above installations. To fix it, we need to prioritize (move up) the git or scoop environment variables in %PATH%.

📦 Install

require("lazy").setup({
  -- Optional for icons.
  { "nvim-tree/nvim-web-devicons" },

  -- Optional for 'fzf' command.
  {
    "junegunn/fzf",
    build = function()
      vim.fn["fzf#install"]()
    end,
  },

  {
    "linrongbin16/fzfx.nvim",
    -- Optional to avoid break changes between major versions.
    version = "v8.*",
    dependencies = { "nvim-tree/nvim-web-devicons", 'junegunn/fzf' },
    config = function()
      require("fzfx").setup()
    end,
  },
})

return require("packer").startup(function(use)
  -- Optional for icons.
  use({ "nvim-tree/nvim-web-devicons" })

  -- Optional for 'fzf' command.
  use({
    "junegunn/fzf",
    run = function()
      vim.fn["fzf#install"]()
    end,
  })

  use({
    "linrongbin16/fzfx.nvim",
    -- Optional to avoid break changes between major versions.
    tag = "v8.0.0",
    config = function()
      require("fzfx").setup()
    end,
  })
end)

call plug#begin()

" Optional for icons.
Plug 'nvim-tree/nvim-web-devicons'

" Optional for 'fzf' command.
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }

" Optional to avoid break changes between major versions.
Plug 'linrongbin16/fzfx.nvim', { 'tag': 'v8.0.0' }

call plug#end()

lua require('fzfx').setup()

🚀 Usage

There're multiple commands provided, named with prefix Fzfx. The sub commands indicates the user query's input method, (i.e. the variants) named with below conventions:

Basic variant is named with args, accepts the following arguments as query content. For example search a file named "README.md" with :FzfxFiles args readme<CR>, search a word "fzfx" with :FzfxLiveGrep args fzfx<CR>.
Visual select variant is named with visual, uses visual selection as query content.
Cursor word variant is named with cword, uses the word text under cursor as query content.
Put (i.e. yank text) variant is named with put (just like press the p key), uses the yank text as query content.
Resume last search variant is named with resume, uses the last search content as query content.

[!NOTE]

The args sub command can be omitted if there is no query text, e.g. :FzfxFiles<CR> is equivalent to :FzfxFiles args<CR>.

The visual select variant is the only variant that works in visual mode, other variants work in normal mode.

Below keys are binded by default:

Exit keys (fzf --expect option)
- esc: quit.
- double-click/enter: open/jump to file (or other behaviors for some specific commands).
Preview keys
- ctrl-]: toggle preview.
- ctrl-f: preview half page down.
- ctrl-b: preview half page up.
Select keys
- ctrl-e: toggle select.
- ctrl-a: toggle select all.

🔧 Configuration

To configure options, please use:

require('fzfx').setup(opts)

The opts is an optional lua table that override the default options.

For complete default options, please see config.lua.

For advanced configurations, please check Advanced Configuration.

Create Your Own Command

Here's a minimal example that implement the ls -1 like FzfxLs command:

https://github.com/linrongbin16/fzfx.nvim/assets/6496887/c704e5b2-d82a-45f2-8920-adeec5d3e7c2

require("fzfx").setup()

require("fzfx").register("ls", {
  --- @type fzfx.CommandConfig
  command = {
    name = "FzfxLs",
    desc = "File Explorer (ls -1)",
  },
  variants = {
    {
      name = "args",
      feed = "args",
      default_provider = "filter_hiddens",
    },
    {
      name = "hidden_args",
      feed = "args",
      default_provider = "include_hiddens",
    },
  },
  --- @type table<string, fzfx.ProviderConfig>
  providers = {
    filter_hiddens = {
      key = "ctrl-h",
      provider = { "ls", "--color=always", "-1" },
      provider_type = "COMMAND_ARRAY",
    },
    include_hiddens = {
      key = "ctrl-u",
      provider = { "ls", "--color=always", "-1a" },
      provider_type = "COMMAND_ARRAY",
    },
  },
  --- @type table<string, fzfx.PreviewerConfig>
  previewers = {
    filter_hiddens = {
      previewer = function(line)
        -- each line is either a folder or a file
        return vim.fn.isdirectory(line) > 0 and { "ls", "--color=always", "-lha", line }
          or { "cat", line }
      end,
      previewer_type = "COMMAND_ARRAY",
    },
    include_hiddens = {
      previewer = function(line)
        return vim.fn.isdirectory(line) > 0 and { "ls", "--color=always", "-lha", line }
          or { "cat", line }
      end,
      previewer_type = "COMMAND_ARRAY",
    },
  },
  actions = {
    ["esc"] = function(lines)
      -- do nothing
    end,
    ["enter"] = function(lines)
      for _, line in ipairs(lines) do
        vim.cmd(string.format([[edit %s]], line))
      end
    end,
  },
  fzf_opts = {
    "--multi",
    { "--prompt", "Ls > " },
  },
})

First setup this plugin, then use require("fzfx").register(name, opts}) api to create your own searching command.

For detailed explanation of each components, please see A Generic Schema for Creating FZF Command and schema.lua.

API References

To help easier customizing/integrating, fzfx provides below modules and APIs.

It's highly recommended to use these APIs when you're creating a new searching command, rather than start from scratch, since they are usually robust and take various situations into consideration.

fzfx.cfg: Top-level configurations that directly register the searching command, such as FzfxFiles, FzfxLiveGrep, etc. Each module is an independent configuration.
fzfx.helper: Line-oriented utilities for parsing user input, query results and rendering the lines for (both left side and right side of) the fzf binary. Since a searching command is actually all about the lines: generating, previewing and invoking binded function on the lines.
fzfx.lib: Fundamental infrastructures, fzfx provides a set of plugin-logic non-related infrastructures to help user implement their own logic.
fzfx.commons: Embedded commons.nvim library as a common utility lua library, please refer to the commons.nvim's documentation for more details.

The commons.nvim library was originally part of fzfx.lib, since I found they're so commonly used and I almost need them for every of my Neovim plugins, I extracted them into this library.

Please see API References for more details.

🪲 Known Issues

Please see Known Issues if you encountered any issue.

🍀 Alternatives

[!NOTE]

This plugin no longer supports nvim native buffer previewer since v8.x, I would recommend fzf-lua if you need it.

fzf.vim: Things you can do with fzf and Vim.
fzf-lua: Improved fzf.vim written in lua.
telescope.nvim: Find, Filter, Preview, Pick. All lua, all the time.
